[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Refer to Figures 1-6 , this embodiment provides a gas purification structure for a kitchen waste solid-liquid waste processor, including a processing chamber, in which a shredding cylinder 1, a heater 2, a condenser 3 and a liquid collection tank 7 are arranged.

[0031] The above-mentioned heater 2 is arranged on the outer bottom surface of the shredding cylinder 1, and the condenser 3 is arranged above the shredding cylinder 1. The liquid in the shredding cylinder 1 is converted into water vapor by the heater 2 to realize the solid-liquid separation of kitchen waste solid-liquid waste, and then condensed into condensed water by the condenser 3. Such a design enables the liquid part to be effectively volatilized and condensed, making the solid component drier, thus facilitating subsequent processing and improving the processing efficiency of kitchen waste.

[0032] The above-mentioned processing chamber includes a top cover plate 9 located above the shredding cylinder 1, and an exhaust air duct 4 and a return air duct 5 are arranged in the top cover plate 9. The input end of the exhaust air duct 4 is an exhaust air inlet 41, which is located above the front end of the shredding cylinder 1; the output end of the return air duct 5 is a return air inlet 51, which is located above the front end of the shredding cylinder 1. This design makes full use of space and improves the structural compactness and stability. The exhaust air inlet 41 is communicated with the condenser 3 through the exhaust air duct 4, and a fan 42 is arranged on the exhaust air duct 4, and the fan 42 is used to intake air towards the condenser 3, so that the water vapor in the shredding cylinder 1 is transported into the condenser 3.

[0033] The input end of the above-mentioned liquid collection tank 7 is communicated with the bottom of the condenser 3, and the output end of the liquid collection tank 7 is communicated with the shredding cylinder 1, and the condensed water flows into the liquid collection tank 7 for subsequent cleaning of the shredding cylinder 1.

[0034] A filter 6 is provided below the above-mentioned condenser 3, and a filter air inlet 63 and a filter air return outlet 64 are provided on the filter 6. The condenser 3 is connected to the filter air inlet 63 through a lower air path 34, and the filter air return outlet 64 is sequentially connected to an upper air path 66 and an air return path 5.

[0035] Specifically, the gas output end of the above-mentioned condenser 3 is not only connected to the lower air path 34, but also connected to the air return path 5. On the gas output end of the condenser 3, the input end of the air return path 5, the input end of the lower air path 34, and the output end of the upper air path 66, on-off controllers are provided. The gas output end of the condenser 3 is divided into two paths by the on-off controllers to form a wet cycle and a dry cycle. A moisture detector is provided at the gas output end of the condenser 3 to detect the moisture in the gas after passing through the condenser 3, so as to select a wet cycle or a dry cycle.

[0036] Wet cycle: When there is too much moisture in the gas after passing through the condenser 3, the connection between the condenser 3 and the air return path 5 is established, the connection between the condenser 3 and the lower air path 34 is blocked, and the connection between the upper air path 66 and the air return path 5 is blocked. After the gas passes through the condenser 3, it directly enters the crushing cylinder 1 through the air return path 5.

[0037] Dry cycle: When the moisture in the gas after passing through the condenser 3 is low, the connection between the condenser 3 and the air return path 5 is blocked, the connection between the condenser 3 and the lower air path 34 is established, and the connection between the upper air path 66 and the air return path 5 is established. After the gas passes through the condenser 3, it enters the filter 6 through the lower air path 34 for filtration, and then enters the crushing cylinder 1 along the upper air path 66 and the air return path 5 in sequence.

[0038] When there is too much moisture in the gas after passing through the condenser 3, a wet cycle is performed until it is detected that the moisture content is lower than the set value, and then it is switched to a dry cycle. This design is to prevent the filter 6 from being saturated due to excessive adsorption of moisture, resulting in a weakened efficacy of adsorbing odors.

[0039] The inlet end of the above-mentioned filter 6 is connected to a filter air inlet path 61, and its outlet end is connected to a filter air return path 62. One end of the filter air inlet path 61 is connected and arranged with the lower air path 34, and the other end is connected and arranged with the filter air inlet 63. One end of the filter air return path 62 is connected and arranged with the upper air path 66, and the other end is connected and arranged with the filter air return outlet 64.

[0040] A liquid extraction port 611 is provided on the above-mentioned filter air inlet path 61, and the liquid at the liquid extraction port 611 is collected into a liquid collection tank 7 by a water pump, so as to prevent the liquid from flowing into the activated carbon in the filter 6, resulting in the failure of the activated carbon.

[0041] There are two pieces of activated carbon, upper and lower, installed inside the above-mentioned filter 6. In order to increase the filtration area and thus improve the adsorption capacity for impurities (such as odors and harmful substances) in the gas. These two pieces of activated carbon are connected through a connecting air duct 65 to ensure that when the gas passes through the filter 6, it can flow effectively to ensure that the gas can fully contact the two pieces of activated carbon, improving the filtration effect. The gas after filtration returns to the shredding cylinder 1.

[0042] A condensation inlet 31 is provided on the above-mentioned condenser 3, and a condensation outlet pipeline 32 is connected in front of the condenser 3. One end of the condensation outlet pipeline 32 is connected to the condenser 3, and the other end is connected to the top cover plate 9. A collection nozzle 33 is provided at the bottom end of the condenser 3, and is connected through a pipeline to a liquid collection tank 7 located below the condenser 3. The exhaust air duct 4 is connected to the condensation inlet 31. The water vapor in the shredding cylinder 1 enters the condenser 3 from the condensation inlet 31 and condenses into condensed water. The condensed water flows into the liquid collection tank 7 from the collection nozzle 33 for storage and is used for subsequent cleaning of the shredding cylinder 1.

[0043] The input end of the lower air duct 34 is connected to the top cover plate 9, and its output end is connected to the filter air inlet 63. The input end of the upper air duct 66 is connected to the filter air return port 64, and its output end is connected to the top cover plate 9. The output end of the condensation outlet pipeline 32, the input end of the lower air duct 34, and the output end of the upper air duct 66 are all located in front of the condenser 3. Moreover, a on-off controller is provided at the connection of the output end of the condensation outlet pipeline 32, the input end of the lower air duct 34, the output end of the upper air duct 66, and the input end of the return air duct 5. The on-off controller is a wind valve control piece 52 to control the on-off between these 4 pipelines.

[0044] Wet cycle: When there is too much moisture in the gas after passing through the condenser 3, the condensation outlet pipeline 32 is connected to the return air duct 5, the condensation outlet pipeline 32 is blocked from the lower air duct 34, and the upper air duct 66 and the return air duct 5 are blocked. After the gas passes through the condenser 3, it directly enters the shredding cylinder 1 through the return air duct 5.

[0045] Dry cycle: When the moisture in the gas after passing through the condenser 3 is low, the condensation outlet pipeline 32 is blocked from the return air duct 5, the condensation outlet pipeline 32 is connected to the lower air duct 34, and the upper air duct 66 and the return air duct 5 are connected. After the gas passes through the condenser 3, it enters the filter 6 through the condensation outlet pipeline 32 and the lower air duct 34 in sequence, and then enters the shredding cylinder 1 through the upper air duct 66 and the return air duct 5 in sequence, realizing the internal circulation of the gas and continuously filtering the gas to avoid gas leakage to the outside and odor leakage.

[0047] A bearing frame 8 is provided below the above-mentioned crushing cylinder 1. The front end of the crushing cylinder 1 is placed above the bearing frame 8, and the liquid collection tank 7 is embedded in the bearing frame 8, making full use of the space and enabling the treatment chamber to have a compact structure and good stability.
