DETAILED DESCRIPTION

[0025] The technical solution of the utility model will be clearly and completely described below through specific implementation methods.

[0026] The utility model provides a domestic waste incinerator, comprising a feeding furnace 1 and a processing furnace 2, and its specific structure is as follows Figure 1 and 2As shown, the feed furnace and the treatment furnace are cylindrical with the same height, and the feed furnace is arranged above the treatment furnace; a garbage inlet 3 is arranged on the top of the feed furnace for domestic garbage to enter. The treatment furnace is connected from top to bottom with an incineration chamber 4, a transition chamber 5 and an evaporation slag chamber 6. Four oxygen supply pipes 7 and an ignition port 8 are arranged on the side wall of the treatment furnace 2 corresponding to the incineration chamber, an oxygen supply pipe 7 is arranged on the side wall corresponding to the transition chamber, and two smoke outlet pipes 9, a slag furnace door 10 and an incineration barrier device are arranged on the side wall corresponding to the evaporation slag chamber. The incineration barrier device is used to prevent the garbage from burning and to discharge the slag produced after burning downward into the evaporation slag chamber.

[0027] The incineration chamber 4 of the utility model is funnel-shaped. Specifically, the incineration chamber is formed by a cylindrical space at the top and an inverted truncated cone-shaped space at the bottom. Figure 3 and 4 As shown, four oxygen supply pipes 7 corresponding to the incineration chamber are evenly arranged on the side wall of the incineration chamber along the circumference, and are arranged in the cylindrical part of the incineration chamber. The ignition port 8 is connected to the inclined part (inverted truncated cone part) of the incineration chamber and is located below the oxygen supply pipe. When igniting, the ignition port is connected to the burner, and the burner ignites and burns the garbage in the combustion chamber through the ignition port 8. Most of the garbage is mainly burned in the inverted truncated cone part in the incineration chamber and the top of the cylinder forming the transition chamber.

[0028] The transition chamber of the utility model is formed by a cylinder 11, the top of the outer side of the cylinder is connected to the bottom of the incineration chamber, the inner side forms the transition chamber, the outer side of the cylinder and the side wall of the treatment furnace form an interlayer 12, the oxygen supply pipe corresponding to the transition chamber is connected to the interlayer 12, and the cylinder side is evenly provided with a number of oxygen supply ports 13 connecting the transition chamber and the interlayer. At the beginning of combustion, part of the garbage is burned in the transition chamber, and the ash produced after combustion and the ash produced by the incineration chamber are gradually accumulated in the transition chamber, so most of the garbage is burned in the incineration chamber.

[0029] The oxygen supply pipes 7 on the incineration chamber and the transition chamber are connected to the blower to input the air with high oxygen content from the outside into the furnace to support combustion, so that the garbage in the furnace burns more fully and comprehensively. The oxygen supply pipe located in the transition chamber first inputs air into the interlayer, and the air in the interlayer then enters the transition chamber through each oxygen supply port to support combustion.

[0030] The blower and the burner are both prior art, and the introduction of air and ignition and combustion through the blower and the burner are both prior art, so they are not described here and are not shown in the accompanying drawings.

[0031] Two smoke outlet pipes 9 are symmetrically arranged on the side wall of the evaporation slag discharge chamber 6. The slag discharge furnace door 10 is arranged on the side wall of the lower part of the evaporation slag discharge chamber. The slag discharge furnace door 10 is used to discharge the slag produced after combustion into the furnace.

[0032] The burning barrier device comprises two rotating rods 14 arranged in parallel on both sides of the slag discharge furnace door. Figure 5 As shown, the two ends of the two rotating rods penetrate the side wall of the treatment furnace and can rotate on the side wall of the treatment furnace. The middle part of each rotating rod evenly extends a number of mutually parallel blocking members 15 in the same direction (when not counterweighted, the blocking members face downward). When it is necessary to burn garbage, the two rotating rods are rotated so that the blocking members on the two rotating rods are close to each other to form a blocking surface 16 set at the bottom of the transition chamber.

[0033] When the blocking surface 16 is formed, counterweights 17 are arranged at both ends of the blocking rod to ensure that the blocking surface is formed to block the garbage from burning.

[0034] Preferably, the utility model further comprises two hot air pipes 18, which are symmetrically arranged on the upper side wall of the feeding furnace. Hot air is introduced into the hot air pipe to dry the incoming garbage. The smoke outlet pipe on the evaporation and slag discharge chamber can be connected to the hot air pipe for hot air circulation, or connected to other smoke treatment devices for smoke treatment before exhausting. Alternatively, one smoke outlet pipe can be connected to the hot air pipe for hot air circulation of the incinerator, and the other smoke outlet pipe can be connected to other devices for smoke treatment.

[0035] The hot blast furnace of the utility model also includes a sewage pipe 19, which is arranged at the lower part of the side wall of the evaporation and slag discharge chamber. Sewage can be introduced, and the sewage is evaporated by the high temperature generated by incineration, and then the slag generated by evaporation and the slag after incineration are discharged together, which has rich functions.

[0036] The height of the treatment furnace and the feeding furnace of the utility model are both 5m. The inclination angle of the inclined edge at the bottom of the incineration chamber is 145 degrees.

[0037] The use principle of the utility model is as follows: when it is necessary to burn garbage, the rotating rod is rotated so that the baffles on the two rotating rods are close to each other to form a baffle surface, and counterweights are set at both ends of the rotating rod to ensure the continuous formation of the baffle surface. The garbage is put into the garbage inlet at the top of the feeding furnace, and the hot air input by the hot air pipe is used to dry the incoming garbage, and then the garbage is ignited and burned through the ignition port. The garbage is mainly burned in the incineration chamber and the transition chamber. During the combustion process, air is introduced through the oxygen supply pipe to assist combustion, so that the garbage in the incineration chamber and the transition chamber can be burned more comprehensively and fully. Part of the slag generated during the combustion process can fall downward into the evaporation slag discharge chamber through the gap between the baffles. After the combustion is completed, the counterweight is removed, and the rotating rod is rotated so that the baffle opens the baffle surface downward, and the remaining slag accumulated in the transition chamber is discharged to the evaporation slag discharge chamber, and discharged through the slag discharge furnace door. The domestic garbage incinerator of the utility model can process domestic garbage more efficiently and fully. It solves the problem that a large amount of domestic garbage occupies land and pollutes the environment.

[0038] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field should fall within the protection scope of the present invention. The technical contents for which protection is sought in the present invention have been fully recorded in the technical requirements.
