Title: Device for accelerating mixing and dissolving process of liquid water

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a device for accelerating mixing and dissolving processes of liquid water and powder poured into the water, and more particularly, to a device for accelerating mixing and dissolving processes of liquid water that is adapted to be mounted on a planetary impeller for a mixer as the existing liquid water dissolving device to more rapidly mix and dissolve the liquid water and the powder poured in the water. 
     2. Background of the Related Art 
     Typically, a liquid water mixer, which is adapted to mix two or more kinds of liquid water and powder inclusive of syringe liquid, includes a mixer body, and an impeller having a plurality of through-holes formed thereon shaft-disposed on the mixer body so as to uniformly mix the two kinds of liquid water supplied to the mixer body, a shaft adapted to connect an output shaft of a motor disposed at one side of the impeller to a housing by means of a bearing so as to rotate the impeller, and a plurality of sealing means like O-rings adapted to prevent the liquid water from being introduced into the shaft disposed on the mixer body and the housing. According to the conventional mixer, however, the driving unit for driving the motor and the impeller is complicated in configuration, which raises the manufacturing cost and makes it hard to perform the assembling and manufacturing processes, and after the mixing has been finished, further, if the mixture is left for a predetermined period of time, the mixed liquid water is hardened into the mixer body, which causes the rotation of the impeller to be interfered. Thus, if the impeller is not driven by means of the interference of the hardened mixture, overload is applied to the motor to cause serious troubles such as malfunctions, breakdown of impeller, electrical leakage, and the like. So as to solve the above-mentioned problems, therefore, there has been proposed Korean Patent No. 017951 entitled ‘planetary impeller for a mixer’, wherein the impeller is open on the top portion thereof in such a manner as to form cooling passages inwardly from the open top portion thereof, through which cooling water is introduced, and a plurality of blades is formed radially along the outer periphery of the impeller in such a manner as to be brought into partial contact with the outer periphery of the impeller, while the upper and lower sides of each blade being spaced apart from the outer periphery of the impeller, thereby preventing foreign matters from being naturally accumulated on the impeller through the vortexes generated by the rotation of the impeller, optimizing the effects of the vortexes generated during the rotation of the impeller, and greatly improving the mixing efficiency of the mixer. 
     The prior art, Korean Patent No. 017951 provides an excellent dissolving efficiency, but if the dissolving time is more shortened, the productivity can be more improved. Therefore, there is a need for the development of a device capable of more reducing the dissolving time. 
     SUMMARY OF THE INVENTION 
     Accordingly, the present invention has been made in view of the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a device for accelerating mixing and dissolving processes of liquid water that is adapted to be mounted on a planetary impeller for a mixer, as disclosed in Korean Patent No. 017951, to more rapidly mix and dissolve the liquid water and the powder poured in the water. 
     To accomplish the above object, according to the present invention, there is provided a device for accelerating mixing and dissolving processes of liquid water and powder, which is adapted to be mounted to cover an impeller therewith, the impeller having an output shaft disposed on a shaft of a motor, a fixing means fitted around the top end periphery of the output shaft, a bearing shaft fitted to the top end periphery of the fixing means, a plurality of blades formed radially along the outer periphery of an impeller body coupled to the bearing shaft, and two or more cooling passages formed on the top surface of the impeller body so as to introduce cooling water thereinto. The device includes a main body formed in a bottle cap shape including a top surface and a side periphery surface, and a shaft disposed at a center of an upper portion of the main body in such a manner as to be inserted into a shaft insertion groove formed at a center of an impeller.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The present invention relates to a device for accelerating mixing and dissolving processes of liquid water that is adapted to be mounted on a planetary impeller for a mixer as the existing liquid water dissolving device to more rapidly mix and dissolve the liquid water and the powder poured in the water. Hereinafter, an explanation on the device according to the present invention will be in detail given with reference to the attached drawings.

     As shown in  FIG. 2 , a device  100  for accelerating mixing and dissolving processes of liquid water according to the present invention includes: a main body  110  formed in a bottle-cap shape including a top surface and a side periphery surface; a shaft  120  disposed at the center of the upper portion of the main body  110  in such a manner as to be inserted into a shaft insertion groove  13  formed at the center of an impeller  10  to rotate the device  100  in the opposite direction to the rotating direction of the impeller  10 ; two or more introducing portions  130  formed on the top surface of the main body  110  to introduce the liquid water and the powder into the device  100 ; and two or more discharging portions  140  formed along the side periphery surface of the main body  110  to discharge the liquid water and the powder introduced into the device  100  through the two or more introducing portions  130  to the outside of the device  100 . 
     Now, an explanation on the operation of the device according to the present invention will be given. 
     First, the impeller  10  as disclosed in Korean Patent No. 017951 is disposed inside a tank (not shown) into which the liquid water and another liquid water, or the liquid water and powder (hereinafter, referred simply to as ‘liquid water’) are contained. As shown in  FIGS. 1 and 3 , the impeller  10  has an output shaft  1  disposed on a shaft of a motor, a fixing means  2  fitted around the top end periphery of the output shaft  1 , a bearing shaft  3  fitted to the top end periphery of the fixing means  2 , a bearing  4  to be disposed around the bearing shaft  3 , and a plurality of blades  11  formed radially along the outer periphery of an impeller body  5  coupled to the bearing shaft  3 . The impeller body  5  includes a top surface  52  and a side surface  54 . Two or more cooling passages  12  are formed on the top surface  52  of the impeller body  5  so as to introduce cooling water into the impeller body  5 . The impeller  10  further includes a shaft insertion groove  13 . And, the main body  110  of the device  100  according to the present invention is provided to cover the impeller  10  from the top side thereof. Next, the shaft  120  of the device  100  is inserted into the shaft insertion groove  13  of the impeller  10  and serves to rotate the device  100  in the opposite direction to the rotating direction of the impeller  10 . The method for rotating the device  100  in the opposite direction to the rotating direction of the impeller  10  is well known in the art, and therefore, it is not explained anymore for the brevity of the description. 
     After that, the impeller  10  rotates the liquid water existing inside the tank to generate vortexes by which the liquid water is mixed, and the liquid water mixed inside the tank is sucked into the vortexes generated by the rotation of the device  100  according to the present invention. Next, the liquid water is rotatingly introduced into the device  100  according to the present invention through the two or more introducing portions  130  and is more rapidly rotated by means of the impeller  10 , thereby allowing the mixing and dissolving processes of the liquid water to be accelerated. As shown in  FIG. 4 , the main body  110  of the device  100  has a top surface  112  and a side periphery surface  114 , and the top surface  112  has the two or more introducing portions  130 . The mixed and dissolved liquid water is pushed by the liquid water continuously introduced through the two or more discharging portions  140  and is discharged to the interior of the tank. The discharged liquid water to the interior of the tank is mixed with the liquid water existing in the interior of the tank. The mixed and dissolved liquid water is introduced again into the device  100  according to the present invention through the two or more introducing portions  130  and is mixed and dissolved again inside the device  100 . Next, the mixed and dissolved liquid water is discharged again through the two or more discharging portions  140 . The processes are repeatedly carried out. 
     The mixing and dissolving processes of the liquid water are carried out repeatedly through the device  100  as well as the impeller  10 , so that the liquid water can be more rapidly mixed. In more detail, the mixing and dissolving processes of the liquid water through only the impeller  10  are carried out for 15 to 20 minutes, but the mixing and dissolving processes of the liquid water through both of the device  100  and the impeller  10  are carried out just for 3 to 5 minutes, which greatly reduces the time required for the mixing and dissolving processes of the liquid water. 
     As described above, there is provided the device for accelerating mixing and dissolving processes of liquid water that is adapted to be mounted on the planetary impeller for the existing mixer, thereby substantially reducing the mixing and dissolving time carried out for 15 to 20 minutes to that for 3 to 5 minutes. 
     While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
