[0036] It also includes an air supply device for supplying fresh air into the mixing chamber 11 and an exhaust device for exhausting waste gas to the outside of the mixing chamber 11.

[0037] As a specific implementation, the combustion device is a diesel burner 71, which is fixed in the combustion chamber 12, and the fuel nozzle of the diesel burner 71 faces the mixing chamber 11, ensuring that the diesel burner 71 is aimed at the kitchen waste in the mixing chamber 11 when burning.

[0038] Specifically in this embodiment, the feeding funnel 13 is arranged on the top of the mixing chamber 11 to facilitate adding kitchen waste into the mixing chamber 11 .

[0039] Furthermore, if Figure 3 and Figure 5 As shown, the present embodiment also includes a sealing plate 31 for sealing the feed funnel 13, and the bottom of the feed funnel 13 is provided with an escape opening (not shown in the figure) for the sealing plate 31 to pass through, and the sealing plate 31 is slidably arranged in the escape opening, and a second drive motor 33 is fixedly arranged on one side of the feed funnel 13, and the second drive motor 33 is connected with a gear (not shown in the figure), and the sealing plate 31 is provided with a rack 32 extending along the sliding direction of the sealing plate 31, and the gear is meshed with the rack 32.

When the sealing plate 31 moves to the inside of the feed funnel 13 through the avoidance port, the funnel mouth of the feed funnel 13 is sealed to prevent the exhaust gas from escaping from the feed funnel 13 when the kitchen waste is burned in the mixing chamber, thereby ensuring the combustion efficiency and combustion effect; when the sealing plate 31 is away from the feed funnel 13, the feed funnel 13 is in an open state, and kitchen waste materials can be added to the mixing chamber 11 through the feed funnel 13.

[0040] Preferably, the second driving motor 33 is connected with a gear via a reducer.

[0041] Specifically in this embodiment, the discharge port 14 is arranged on one side of the mixing chamber 11 and close to the bottom of the mixing chamber 11. A sealing door 41 for sealing the discharge port 14 is slidably provided on the outer side of the mixing chamber 11, and also includes an electric push rod 42 for driving the sealing door 41 to move.

[0042] Specifically, the two sides of the discharge port 14 are respectively provided with limit seats 44 arranged parallel to each other, and the inner side of the limit seat 44 (the side opposite to the two limit seats 44 is the inner side) is provided with a guide groove (not shown in the figure) that slides with the sealing door 41, and the two sides of the sealing door 41 are respectively slidably set in the corresponding guide grooves to ensure that the sealing door 41 can be close to the outer wall of the mixing chamber 11 and form a seal for the discharge port 14.

[0043] Specifically, a connection seat 43 is provided on the outer side of the mixing chamber 11, the electric push rod 42 is hinged on the connection seat 43, and the driving arm of the electric push rod 42 is hinged with the sealing door 41.

[0046] As a specific implementation, the air delivery device includes a fresh air blower 51, and the fresh air blower 51 is connected to the mixing chamber 11 through an air filter 52. The fresh air blower 51 is fixed to the outside of the mixing chamber 11 through a fastener, and the fresh air blower 51 and the air filter 52, and the air filter 52 and the mixing chamber 11 are connected in series through ventilation ducts.

[0047] As a specific implementation, the exhaust device includes a muffler 61 and a dust removal pipe 62 which are connected in series with the stirring chamber 11 .

[0048] It should be noted that the present embodiment also includes a controller 81 for controlling the operation of the first drive motor 24, the second drive motor 33, the electric push rod 42, the fresh air fan 51, and the diesel burner 71. The operation process of the controller 81 is through the electronic control system. The system adopts SIMATICS7200PLC, touch screen control and temperature acquisition sensor, and online moisture tester. It is fully automatic. The detection signals of the system include: material moisture content, material temperature, combustion temperature, exhaust temperature, fresh air temperature, pressure in the mixing bin, etc. The field sensor converts the above parameters into voltage or current values ​​and inputs them into the PLC.

The above system, touch screen control and temperature acquisition sensor, and online moisture tester belong to the existing conventional technology, and their specific setting methods are not described in detail here.

[0049] Working principle: When in use, the kitchen waste is lifted by a hoist or a forklift and then fed into the mixing chamber 11 through the feeding funnel 13. After the feeding is completed, the feeding funnel 13 drives the sealing plate 31 to automatically operate through the second driving motor 33 so that the feeding funnel 13 is automatically closed to achieve a sealing effect;

[0050] The diesel burner 71 in the combustion chamber 12 automatically ignites and burns to generate a heat source. The diesel burner 71 burns and decomposes the food waste in the mixing chamber 11. The first drive motor 24 drives the mixing shaft 21 and the spiral blades 22 to rotate, stirring the food waste so that the food waste is heated, burned and decomposed more evenly. The fresh air blower 51 is started at the same time to transport the filtered air through the filter element 52 into the mixing chamber 11, so as to burn, heat and supplement oxygen to the mixing chamber 11.

[0051] The odor and water vapor generated by the combustion and decomposition of the kitchen waste rise through the pipe connected to the combustion chamber 12 to the muffler 61, and are discharged from the combustion chamber 12 through the dust removal pipe 62 after silencer. The remaining ash and residue that retain a part of the heat remain at the bottom of the mixing chamber 11, and the second batch of processed materials are supplementarily heated at the bottom of the tank, thereby achieving the purpose of energy saving and consumption reduction.

[0052] After the material reaction is completed, the sealing door 41 is opened by the electric push rod 42 , and by controlling the forward and reverse rotation of the first drive motor 24 , the forward and reverse rotation settings of the spiral blade 22 are further controlled to discharge all the materials from the discharge port 14 .

[0053] The spiral blade 22 rotates alternately forward and reverse at a speed of about 4.3r / min. The fresh air blower 51 runs at a low speed to form a slight negative pressure in the mixing chamber 11. After the material is added from the feed hopper 13, the feed door is closed; the fresh air blower 51 and the diesel burner 71 are turned on, and the material is evenly stirred by the spiral blades while being heated by the heat energy from the diesel burner 71 and the remaining heat energy at the bottom of the tank, which promotes the high-temperature rapid aerobic fermentation of the material and the vaporization of the internal water; the evaporated humid gas (with fermentation odor) is deodorized and dehumidified by the high-temperature combustion chamber 12, and after passing through the muffler 61 and the dust removal pipe 62, it is treated by external deodorization and reaches the discharge standard. The remaining material is discharged from the discharge port 14 after reaching the moisture content requirement.

[0054] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
