Title: Industrial dust-collector

Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to an industrial dust-collector with innovatory features, and more particularly to an industrial dust-collector which can efficiently collect solid industrial waste in a dust-collecting bag and can be conveniently operated for the bag of solid industrial waste to be taken out for retrieve and treatment, so as to save time and labor. 
   2. Brief Description of the Prior Art 
   At present, in common factories, raw materials,such as plastic grains, soya beans, or metal scraps will fall on the ground while machines being operated. These solid industrial waste must be disposed by industrial dust-collectors. 
   Referring to  FIG. 1 , a conventional industrial dust-collector is composed by a main body  10 , an upper cover  101 , a motor  102 , a fan  103 , a filtering device  104  and a floating ball  105 . The upper cover  101  is installed on the top of the main body  10 , the motor  102  under the upper cover  101 , the fan  103  under the motor  102 , and the filtering device  104  and the floating ball  105  under the fan  103 . 
   Referring to  FIG. 2 , while being operated, the motor  102  and the fan  103  of the conventional dust-collector are started to suck the solid industrial waste  106  through the suction pipe  107  to the chamber  108  inside the main body  10 . When the collected solid industrial waste  106  reaches a certain height, the cover  101  is opened for the solid industrial waste  106  to be dumped or shoveled, as shown in FIG.  3 . 
   However, there are following drawbacks in the above-described structure and operation of the conventional industrial dust-collector 
   1. When the chamber inside the main body is filled with solid industrial waste, it is necessary to open the upper cover to dump or shovel the solid industrial waste. Since the main body is considerably weighty, it takes time and pain to do so. 
   2. It wastes time and labor to retrieve and treat the dumped solid industrial waste. 
   SUMMARY OF THE INVENTION 
   Therefore, the objective of the present invention is to provide an industrial dust-collector that can substantially obviate the drawbacks of the related conventional industrial dust-collector. 
   An objective of the present invention is to provide an industrial dust-collector that can efficiently collect solid industrial waste in a dust-collecting bag. 
   Another objective of the present invention is to provide an industrial dust-collector which can be conveniently operated for the bag of solid industrial waste to be taken out for retrieve and treatment, so as to save time and labor. 
   Accordingly, an industrial dust-collector in the present invention is provided with an air blower in the bottom of the base. An air-inlet line and an air-out line are provided at the front of the air blower. A cover is provided on the top of the base, a sucking pipe is provided at the top of the cover, and both sides of the cover are respectively provided with a buckle article. A door and a pushing rod are provided at the exterior of the base. The characteristic lies in that an air-guiding block is provided in the bottom of the cover, a plurality of air-guiding holes are provided in the bottom of air-guiding block, an elastic ring is provided at the bottom of the air-guiding block to secure the top section of a dust-collecting bag and a sleeve tube, the sleeve tube is hollow, and a plurality of through holes are provided around the sleeve tube.
