Problems solved by technology

According to French experts, the completion and use of this new type of garbage disposal site will greatly improve the quality of special garbage disposal in France and reduce the pollution caused by garbage disposal to the atmosphere. Garbage is put directly into the incinerator. This way of putting in garbage will cause the crushed garbage to accumulate in one place, thus affecting the pyrolysis efficiency of the garbage in the incinerator. At the same time, domestic garbage is often mixed with a lot of water. If it will bring The domestic waste with moisture is directly put into the incinerator, which will reduce the temperature in the incinerator, thereby reducing the pyrolysis efficiency of domestic waste and increasing the generation of polluting gases

Embodiment 1

[0043] Such as figure 1 , image 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the blanking mechanism 4 includes a blanking motor 41, a blanking pipe 42, and a blanking screw 43. The lower end of the blanking pipe 42 is connected to the top side of the incinerator 6 by bolts, and the blanking motor 41 is connected to the blanking pipe 42 by bolts. One end, one end of the feeding screw 43 is connected to the inner side of the feeding pipe 42 through a bearing, and the rotating part of the feeding motor 41 is used to drive the feeding screw 43 to rotate inside the feeding pipe 42, so as to push and discharge the crushed domestic waste Drying mechanism 2 comprises drying box 21, feeding motor 22, feeding roller 23, feeding belt 24, and drying box 21 upper end is installed on the feeding pipe 42 upper side, and feeding motor 22 is connected to drying box 21 lower end front side by bolt, and feeding roller 23 Connected to the inner side of the drying box 21 throu...

Embodiment 2

[0046] Such as figure 2 , Figure 4 As shown, the difference between Embodiment 2 and Embodiment 1 is that the drive mechanism 5 includes a drive motor 51, a fixed mount 52, a pulley 513, and a belt 514, and the fixed mount 52 is installed on the top of the incinerator 6, and the drive motor 51 is connected to the On the fixed frame 52, the pulley 513 is connected to the rotating part of the driving motor 51 and the rotating tube 12 by a key, and the belt 514 is arranged on the outside of the pulley 513, and the driving motor 51 is supported and fixed by the fixed frame 52, and the driving motor 51 is used to rotate part to drive the pulley 513 to rotate, and the transmission of the pulley 513 and the belt 514 to drive the rotating tube 12 to rotate.

Abstract

The invention discloses a low-temperature pyrolysis device for reduction treatment of urban domestic wastes. The low-temperature pyrolysis device comprises a drying mechanism, a discharging mechanism, a driving mechanism for providing power for discharging of the domestic wastes, an incinerator and an air inlet pipe, wherein the drying mechanism is located on one side of the incinerator, and the discharging mechanism is located on one side of the top of the incinerator. For the low-temperature pyrolysis device disclosed by the invention, gas produced by pyrolysis is fed into a drying box through a gas feeding pipe and a pipe frame, so that the domestic wastes to be put into the incinerator is heated and dried, and then the whole pyrolysis efficiency is improved; and cold water is fed into a rotating pipe and a cavity of a rotating plate through a rotating connector, heated water is guided outsides through a water outlet pipe, and the rotating pipe is used for driving the rotating plate to rotate on a partition plate at the same time, so that the crushed domestic wastes are evenly scattered in the incinerator and then are evenly heated and decomposed.

Description

technical field [0001] The invention relates to the field of domestic waste reduction treatment, in particular to a low-temperature pyrolysis device used for the reduction treatment of urban domestic waste. Background technique [0002] Pyrolysis After nearly ten years of research and construction, France's first pyrolysis waste disposal site is expected to be put into use in Eure-Loire within this year. According to French experts, the completion and use of this new type of waste disposal site will greatly improve the quality of special waste disposal in France and reduce the pollution caused by waste disposal to the atmosphere. Garbage is put directly into the incinerator. This way of putting in garbage will cause the crushed garbage to accumulate in one place, thereby affecting the pyrolysis efficiency of the garbage in the incinerator. At the same time, domestic garbage is often mixed with a lot of water. If it will bring If the domestic waste with moisture is directly ...
