Title: Carcass cremator

Description:
BACKGROUND OF THIS INVENTION 
     This invention relates to a carcass cremator, and more particularly to a cremator for animal remains which can be burned quickly with strong flames. 
     Domestic animals and poultry are often dead because of fowl pest, septicemic plague, and other epidemical pestilence. The carcasses which are poured with oil are disposed on a large pan, and the carcasses are burned. If the carcasses are too large, they must be cut into small pieces before they are burned. However, the smell of the burning oil is stink and the smaze is very concentrated. It takes a long period of time in order to burn the carcasses completely. Therefore, it wastes oil and time in conventional carcass cremation. 
     SUMMARY OF THIS INVENTION 
     The main object of this invetion is to provide a carcass cremator which can concentrate strong flames to cremate the carcasses almost completely. 
     Another object of this invention is to provide a carcass cremator which can cremate the carcasses in an array. 
     A further object of this invention is to provide a carcass cremator which can cremate the carcasses quickly at very low cost.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The features of this invention are described as follows. An inner chamber is defined by fireproof materials such as fireproof bricks, stones, clinkers and firebricks. The fireproof materials which become the walls of the inner chamber surround the inner chamber, and the inner chamber is thus formed. At least two thirds of the inner chamber is buried underground. A tube that supports the metal bowl is disposed approximately at the center of the inner chamber. A metal bowl is disposed on the tube. A top cover covers the top portion of the inner chamber. A flame inlet is formed at the lower portion of the fireproof wall. A vortex space or helix space is formed in the inner chamber in order to allow the strengthening and concentration of the flames. 
     A preferred embodiment of this invention is described in the following paragraphs. 
     Referring to FIGS. 1 to 3, a large cave which has predetermined depth underground is formed. The periphery of the large cave is paved by fireproof material such as firebricks 1 to form a fireproof wall. The fireproof wall forms an inner chamber 2 therein. Referring to FIG. 2, a flame inlet 11 is formed at the lower portion of the wall which is under the height(h) from the bottom of the wall. A vortex (or eddy) space 21 which flares gradually and upwardly along the wall is formed in the interior of the inner chamber 2. A tube 3 that supports a metal bowl 4 is disposed approximately at the center of the inner chamber 2. The top portion of the tube 3 is flat so that a metal bowl 4 can be disposed on the tube 3. A top cover 5 which has a central hole 51 is disposed on the top portion of the inner chamber 2. The central hole 51 has a diameter smaller than that of the top portion of the bowl 4. Therefore, spacing 7 is formed between the top cover 5 and the bowl 4 so that the flames can spread out. A plurality of gaps 52 are formed on the top portion of the top cover 5 to allow the expansion and contraction of the top cover 5. 
     Referring to FIGS. 2 and 3, a carcass 6 is placed on the top cover 5, and a combustion machine is disposed at the flame inlet 11 to ignite strong flames 8. The flames 8 spread upwardly along the vortex space 21 and spread outwardly along the spacing 7 so that the middle portion of the carcass 6 is burned by the rapid and strong flames 8. Referring to FIG. 4, the middle portion of the carcass 6 is burned by the flames 8. Referring to FIG. 5, the middle portion of the carcass 6 is softened and descended into the bowl 4 gradually. The bowl 4 burns the remains of the carcass 6 continuously with strong flames and high temperatures. Referring to FIG. 6, a hollow metal barrel 9 covers the central hole 51 of the top cover 5 to form a top chamber after the carcass 6 falls down to the bowl 4 so that the flames 8 can be concentrated in the inner chamber 2. Therefore, the carcass 6 is completely cremated. The ash can be easily removed from the bowl 4 after the carcass 6 is cremated completely. FIG. 7 shows an array of the carcasses 6 which are placed on the top cover 5 and are ready for cremation. It is very convenient to cremate an array of the carcasses with the assembly of this invention. Furthermore, the vortex space can concentrate and strengthen the flames. The strong and concentrated flames can cremate the carcasses very quickly at very low cost.
