DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-8 This embodiment provides a processing chamber A and a collecting chamber B, and the processing chamber A and the collecting chamber B are separated by a middle partition 10, that is, the middle partition 10 serves as the bottom wall of the processing chamber A and the top wall of the collecting chamber B.

[0020] The processing chamber A is provided with a crushing cylinder 1, a conveying channel 11, a bearing frame 12 and a liquid collecting box 7, and the collecting chamber B is provided with a filter 6 and a liquid storage box 8. The bearing frame 12 is connected to the upper end surface of the middle partition 10, and the filter 6 and the liquid storage box 8 are connected to the lower end surface of the middle partition 10. The front end of the crushing cylinder 1 is mounted above the bearing frame 12, and the liquid collecting box 7 is placed in the bearing frame 12, so that the space is fully utilized, so that the processing chamber A has a compact structure and good stability.

[0021] Separate hatches 13 are respectively provided in front of the above-mentioned crushing cylinder 1 and the conveying channel 11, and a separate hatch 13 is provided on the upper liquid of the collecting chamber B.

[0022] The liquid collecting tank 7 can store clean water. The liquid collecting tank 7 is connected to the crushing cylinder 1 through a pipeline provided with a water pump. The water pump sprays clean water into the crushing cylinder 1 to achieve a cleaning effect. The liquid storage tank 8 is arranged below the liquid collecting tank 7. The liquid storage tank 8 contains decomposition liquid and fermentation liquid for decomposing and fermenting the processed material in the crushing cylinder 1. The filter 6 is arranged behind the liquid storage tank 8 for purifying the gas in the crushing cylinder 1.

[0023] The above-mentioned crushing cylinder 1 is provided with a rotating blade 101 and a fixed blade 102. The rotating blade 101 is rotatably connected in the crushing cylinder 1, and the fixed blade 102 is fixedly connected to the inner wall surface of the crushing cylinder 1. The crushing effect of solid and liquid kitchen waste is achieved by the rotating blade 101 and the fixed blade 102. The transmission channel 11 is located below the crushing cylinder 1, and the crushing cylinder 1 is connected to the collection chamber B through the transmission channel 11. The processed material after being processed by the crushing cylinder 1 enters the collection chamber B for collection through the transmission channel 11. Specifically, a retractable baffle is provided at the bottom of the crushing cylinder 1. When the kitchen waste in the crushing cylinder 1 is processed, the baffle is opened, so that the processed material enters the collection chamber B through the transmission channel 11.

[0024] A heater 2 is provided on the outer bottom surface of the above-mentioned crushing cylinder 1, and a condenser 3 is also provided in the processing chamber A. The condenser 3 is located above the crushing cylinder 1, and the bottom end of the condenser 3 is connected to the liquid collecting tank 7 through a pipeline. The liquid in the crushing cylinder 1 is converted into water vapor through the heater 2 to achieve solid-liquid separation of solid and liquid kitchen waste, and then condensed through the condenser 3 to form condensed water, which flows into the liquid collecting tank 7 along the pipeline for storage and can be used for subsequent cleaning of the crushing cylinder 1. This design allows the liquid part to be effectively volatilized and condensed, making the solid component drier, thereby facilitating subsequent processing and improving the processing efficiency of kitchen waste.

[0025] The processing chamber A comprises a top cover plate 9 located above the crushing cylinder 1, and an exhaust path 4 and a return air path 5 are arranged in the top cover plate 9. The input end of the exhaust path 4 is an exhaust port 401, which is located above the front end of the crushing cylinder 1; the output end of the return air path 5 is a return air port 501, which is located above the front end of the crushing cylinder 1. The crushing cylinder 1 is connected to the condenser 3 through the exhaust path 4, and a fan 402 is arranged on the exhaust path 4. The fan 402 blows air toward the condenser 3, so that the water vapor in the crushing cylinder 1 is transported to the condenser 3.

[0026] The filter 6 is provided with a filter air inlet 603 and a filter air return port 604. The gas output end of the condenser 3 is connected to the filter air inlet 603 through the downwind path 304, and the filter air return port 604 is connected to the upwind path 606 and the return air path 5 in sequence.

[0027] The gas output end of the above-mentioned condenser 3 is not only connected to the downwind path 304, but also connected to the return air path 5. The gas output end of the condenser 3, the input end of the return air path 5, the input end of the downwind path 304, and the output end of the upwind path 606 are provided with an on-off controller. The gas output end of the condenser 3 is divided into two paths to form a wet cycle and a dry cycle through the on-off controller. 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.

[0028] Wet cycle: When there is too much moisture in the gas after passing through the condenser 3, the condenser 3 is connected to the return air path 5, the condenser 3 and the downwind path 304 are blocked, and the upwind path 606 and the return air path 5 are blocked. After passing through the condenser 3, the gas directly enters the crushing cylinder 1 through the return air path 5.

[0029] Dry cycle: When the moisture content of the gas after passing through the condenser 3 is low, the condenser 3 and the return air path 5 are blocked, the condenser 3 and the downwind path 304 are connected, and the upwind path 606 and the return air path 5 are connected. After passing through the condenser 3, the gas enters the filter 6 through the downwind path 304 for filtration, and then enters the crushing cylinder 1 along the upwind path 606 and the return air path 5 in turn.

[0030] When there is too much moisture in the gas after passing through the condenser 3, a wet cycle is performed until the moisture content is detected to be lower than the set value, and then it is switched to a dry cycle. This design is to prevent the filter 6 from becoming saturated due to adsorption of excessive moisture, thereby reducing the effectiveness of adsorbing odors.

[0031] The inlet end of the above-mentioned filter 6 is connected to a filter air inlet path 601, and the outlet end thereof is connected to a filter return air path 602. One end of the filter air inlet path 601 is connected to the downwind path 304, and the other end thereof is connected to the filter air inlet port 603. One end of the filter return air path 602 is connected to the upwind path 606, and the other end thereof is connected to the filter return air port 604.

[0032] The filter air inlet 601 is provided with a water pumping port 6011, and the liquid at the water pumping port 6011 is collected into the liquid collecting box 7 by a water pump to prevent the liquid from flowing into the activated carbon in the filter 6, thereby causing the activated carbon to become ineffective.

[0033] The filter 6 is provided with two upper and lower activated carbons to increase the filtering area and thus improve the adsorption capacity of impurities (such as odor and harmful substances) in the gas. The two activated carbons are connected by a connecting air duct 605 to ensure that the gas can flow effectively when passing through the filter 6 and ensure that the gas can fully contact the two activated carbons, thereby improving the filtering effect, and the filtered gas returns to the crushing cylinder 1.

[0034] The condenser 3 is provided with a condensation inlet 301, and a condensation outlet pipeline 302 is connected in front of the condenser 3. One end of the condensation outlet pipeline 302 is connected to the condenser 3, and the other end is connected to the top cover plate 9. A collecting nozzle 303 is provided at the bottom of the condenser 3, and is connected to the liquid collecting tank 7 located below the condenser 3 through a pipeline. The exhaust path 4 is connected to the condensation inlet 301, and the water vapor in the crushing cylinder 1 enters from the condensation inlet 301 to condense into condensed water, and the condensed water flows from the collecting nozzle 303 into the liquid collecting tank 7 for storage for subsequent cleaning of the crushing cylinder 1.

[0035] The input end of the downwind path 304 is connected to the top cover plate 9, and the output end thereof is connected to the filter air inlet 603. The input end of the upwind path 606 is connected to the filter return air port 604, and the output end thereof is connected to the top cover plate 9. The output end of the condensation outlet pipeline 302, the input end of the downwind path 304, and the output end of the upwind path 606 are all located in front of the condenser 3. Moreover, an on-off controller is provided at the connection of the output end of the condensation outlet pipeline 302, the input end of the downwind path 304, the output end of the upwind path 606, and the input end of the return air path 5. The on-off controller is a wind valve control sheet 502 to control the on-off between the four pipelines.

[0036] Wet cycle: When there is too much moisture in the gas after passing through the condenser 3, the condensation outlet pipe 302 is connected to the return air path 5, the condensation outlet pipe 302 and the downwind path 304 are blocked, and the upwind path 606 and the return air path 5 are blocked. After passing through the condenser 3, the gas directly enters the crushing cylinder 1 through the return air path 5.

[0037] Dry cycle: When the moisture content of the gas after passing through the condenser 3 is low, the condensation outlet pipe 302 and the return air path 5 are blocked, the condensation outlet pipe 302 and the downwind path 304 are connected, and the upwind path 606 and the return air path 5 are connected. After the gas passes through the condenser 3, it enters the filter 6 along the condensation outlet pipe 302 and the downwind path 304 in turn for filtration, and then enters the crushing cylinder 1 along the upwind path 606 and the return air path 5 in turn, realizing the internal circulation of the gas and continuously filtering the gas to avoid gas leakage to the outside and odor leakage.

[0038] See also Figure 9-11 The bottom of the liquid storage box 8 is recessed inward to separate the liquid storage box 8 into a first liquid storage area 801 and a second liquid storage area 802. The first liquid storage area 801 stores decomposition liquid, and the second liquid storage area 802 stores fermentation liquid. The decomposition liquid sprayed on the kitchen waste can help decompose the waste and remove certain oil and salt components. The fermentation liquid can help the waste to further ferment. These two liquids can help the waste to be converted into fertilizer with more fertility.

[0039] The liquid storage box 8 is provided with a first liquid outlet 8011 and a second liquid outlet 8021. The first liquid outlet 8011 is connected to the first liquid storage area 801 through a pipeline, and the second liquid outlet 8021 is connected to the second liquid storage area 802 through a pipeline. Furthermore, a partition plate 803 is provided above the inner cavity. The partition plate 803 is detachable, which further increases the spacing height between the first liquid storage area 801 and the second liquid storage area 802 and improves the storage capacity. At the same time, a through hole is provided on the partition plate 803, which is used to clamp the pipeline to prevent it from being loose.

[0040] The top plate is provided with a first liquid spraying port 804 and a second liquid spraying port 805. The first liquid spraying port 804 is connected to the liquid storage tank 8 through a pipeline, and the second liquid spraying port 805 is connected to the liquid collecting tank 7 through a pipeline. Liquid is sprayed into the inside of the crushing cylinder 1 through the first liquid spraying port 804 and the second liquid spraying port 805. In order to avoid the decomposition liquid and the fermentation liquid from polluting the sprayed clean water, the first liquid spraying port 804 is used to spray the decomposition liquid and the fermentation liquid, and the second liquid spraying port 805 is used to spray the clean water.

[0041] For further information, see Fig.12 A spray box 14 is provided below the condenser 3 to receive the condensed water discharged from the condenser 3. The output end of the spray box 14 is connected to the liquid collecting tank 7. Part of the condensed water in the spray box 14 is discharged to the surrounding environment in the form of spray, and the other part of the condensed water can be stored in the liquid collecting tank 7. The liquid collecting tank 7 and the spray box 14 are respectively provided with water level detection devices to monitor the liquid level in real time. A sprayer is provided in the spray box 14 to discharge the liquid in the spray box 14 in the form of spray. When the water level monitoring device detects that the water in the liquid collecting tank 7 is full, and when the condensed water in the spray box 14 reaches a certain height (i.e., the set starting water level), the sprayer is triggered to start and discharge the condensed water into the surrounding environment in the form of spray, thereby reducing the liquid capacity in the spray box 14. Among them, the spray box 14 and the liquid collecting tank 7 can be disassembled, and the internal condensed water is dumped according to actual conditions.
