DETAILED DESCRIPTION

[0029] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts under the premise that no creative efforts are made, belong to the scope of protection of the present application.

[0030] Referring to Figs. 1-6, the embodiment provides a gas purification structure of a kitchen solid-liquid waste processor, which comprises a treatment cabin, the treatment cabin is internally provided with a crushing cylinder 1, a heater 2, a condenser 3 and a liquid collecting tank 7.

[0031] The heater 2 is arranged on the outer bottom surface of the crushing cylinder 1, and the condenser 3 is arranged above the crushing cylinder 1. The heater 2 is used to convert the liquid in the crushing cylinder 1 into water vapor, so as to realize solid-liquid separation of the kitchen solid-liquid waste, and then the condenser 3 is used to condense the water vapor to form condensed water. This design can effectively volatilize and condense the liquid part, and make the solid component drier, so as to facilitate subsequent processing and improve the processing efficiency of the kitchen waste.

[0032] The treatment cabin comprises a top cover plate 9 arranged above the crushing cylinder 1, and the top cover plate 9 is internally provided with an air extraction path 4 and an air return path 5. The input end of the air extraction path 4 is an air extraction port 41, which is arranged above the front end of the crushing cylinder 1, and the output end of the air return path 5 is an air return port 51, which is arranged above the front end of the crushing cylinder 1. This design makes full use of the space, and improves the compactness and stability of the structure. The air extraction port 41 is arranged in communication with the condenser 3 through the air extraction path 4, and a fan 42 is arranged on the air extraction path 4. The fan 42 is used to send air to the condenser 3, so that the water vapor in the crushing cylinder 1 is transported into the condenser 3.

[0033] The input end of the liquid collecting tank 7 is in communication with the bottom of the condenser 3, the output end of the liquid collecting tank 7 is in communication with the crushing cylinder 1, and the condensed water flows into the liquid collecting tank 7 for subsequent cleaning of the crushing cylinder 1.

[0034] The condenser 3 is arranged below the filter 6, and the filter 6 is provided with a filter air inlet 63 and a filter air return port 64. The condenser 3 is connected with the filter air inlet 63 through a lower air path 34, and the filter air return port 64 is sequentially connected with an upper air path 66 and the air return path 5.

[0035] Specifically, the gas output end of the condenser 3 is connected with not only the lower air path 34, but also the air return path 5. 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 are provided with an on-off controller. The on-off controller divides the gas output end of the condenser 3 into two paths to form a wet cycle and a dry cycle. A moisture detector is arranged on the gas output end of the condenser 3, which is used to detect the moisture in the gas after passing through the condenser 3, so as to select the wet cycle or the dry cycle.

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

[0037] Dry cycle: when the moisture in the gas after passing through the condenser 3 is low, the communication between the condenser 3 and the return air path 5 is blocked, the communication between the condenser 3 and the lower air path 34 is communicated, the communication between the upper air path 66 and the return air path 5 is communicated, and the gas passing through the condenser 3 enters the filter 6 after being filtered through the lower air path 34, and then enters the crushing cylinder 1 along the upper air path 66 and the return air path 5.

[0038] When the moisture in the gas after passing through the condenser 3 is too much, the wet cycle is performed, and when the moisture content is detected to be lower than the set value, the dry cycle is switched, which is designed to prevent the filter 6 from being saturated due to the absorption of too much moisture, thereby reducing the effectiveness of adsorbing odors.

[0039] The inlet end of the filter 6 is connected with a filter inlet air path 61, and the outlet end is connected with a filter return air path 62. One end of the filter inlet air path 61 is in communication with the lower air path 34, and the other end is in communication with the filter inlet 63. One end of the filter return air path 62 is in communication with the upper air path 66, and the other end is in communication with the filter return air outlet 64.

[0040] A water suction port 611 is provided on the filter inlet air path 61, and the liquid at the water suction port 611 is collected into the liquid collecting tank 7 by the water pump, so as to avoid the liquid flowing into the activated carbon in the filter 6, thereby causing the activated carbon to be ineffective.

[0041] Two pieces of activated carbon are installed in the filter 6, in order to increase the filtering area and improve the adsorption capacity of impurities (such as odors and harmful substances) in the gas. The two pieces of activated carbon are communicated through the connecting air duct 65, which ensures that the gas can flow effectively when passing through the filter 6, and ensures that the gas can fully contact the two pieces of activated carbon, thereby improving the filtering effect. The filtered gas returns to the crushing cylinder 1.

[0042] The condenser 3 is provided with a condensing inlet 31, and a condensing outlet pipeline 32 is communicated in front of the condenser 3. One end of the condensing outlet pipeline 32 is connected with the condenser 3, and the other end is connected with the top cover plate 9. The bottom end of the condenser 3 is provided with a collecting nozzle 33, and is communicated with the liquid collecting tank 7 located below the condenser 3 through a pipeline. The air suction path 4 is communicated with the condensing inlet 31, and the water vapor in the crushing cylinder 1 enters the condenser 3 from the condensing inlet 31 to be condensed into condensed water, and the condensed water flows into the liquid collecting tank 7 through the collecting nozzle 33 for storage for subsequent cleaning of the crushing cylinder 1.

[0043] The input end of the lower air passage 34 is connected with the top cover plate 9, and the output end is communicated with the filter air inlet 63. The input end of the upper air passage 66 is communicated with the filter air outlet 64, and the output end is connected with the top cover plate 9. The output end of the condensing outlet pipeline 32, the input end of the lower air passage 34 and the output end of the upper air passage 66 are all located in front of the condenser 3. Moreover, a switch controller is arranged at the connection of the output end of the condensing outlet pipeline 32, the input end of the lower air passage 34, the output end of the upper air passage 66 and the input end of the return air passage 5. The switch controller is a wind valve control piece 52, which controls the switch between the four pipelines.

[0044] Wet cycle: when the water content in the gas after passing through the condenser 3 is too much, the communication between the condensing outlet pipeline 32 and the return air passage 5 is opened, the communication between the condensing outlet pipeline 32 and the lower air passage 34 is blocked, and the communication between the upper air passage 66 and the return air passage 5 is blocked. After the gas passes through the condenser 3, it directly enters the crushing cylinder 1 through the return air passage 5.

[0045] Dry cycle: when the water content in the gas after passing through the condenser 3 is low, the communication between the condensing outlet pipeline 32 and the return air passage 5 is blocked, the communication between the condensing outlet pipeline 32 and the lower air passage 34 is opened, and the communication between the upper air passage 66 and the return air passage 5 is opened. After the gas passes through the condenser 3, it enters the filter 6 through the condensing outlet pipeline 32 and the lower air passage 34 in sequence, and then enters the crushing cylinder 1 through the upper air passage 66 and the return air passage 5 in sequence, realizing the internal circulation of the gas, continuously filtering the gas, and avoiding the leakage of the gas to the outside and the emission of odor.
