Description

Technical Field

[0001] This utility model relates to the field of fermentation technology, and in particular to a screening and cleaning device. Background Technology

[0002] Fermentation of fermented bean curd mainly relies on enzymes secreted by microorganisms, which catalyze complex changes in the components of the tofu and seasonings. Proteins hydrolyze, and sugars ferment to produce ethanol and various alcohols, which then combine with organic acids to synthesize esters, giving fermented bean curd its unique flavor and mellow taste. In the production of fermented bean curd, screening and cleaning equipment is crucial. It can clean the machine to ensure the cleanliness of the materials, laying a solid foundation for subsequent processes and ensuring the smooth operation of fermented bean curd production.

[0003] Traditional methods of screening and cleaning fermented bean curd mostly rely on manual operation, requiring staff to select and clean each block of tofu individually. This method not only consumes a lot of labor and increases labor costs, but also takes a long time and is inefficient, making it difficult to meet the needs of large-scale production. The nozzle spacing in existing screening and cleaning equipment is mostly fixed, making it difficult to adapt to different sizes of tofu, resulting in uneven cleaning coverage and affecting the cleaning effect.

[0004] Therefore, those skilled in the art have provided a screening and cleaning device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a screening and cleaning device that adjusts the nozzle spacing through an adjustment mechanism and allows the filter to move continuously, preventing it from becoming clogged.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A screening and cleaning device includes a main body, an adjustment mechanism inside the main body, the adjustment mechanism including two connecting frames and four connecting parts, multiple connecting blocks rotatably arranged on both sides of the four connecting parts, two bidirectional lead screws rotatably arranged inside the main body, a first motor fixedly arranged at the rear end inside the main body, and two sliders threadedly connected to the outside of the two bidirectional lead screws.

[0008] The first motor output end is provided with a first linkage mechanism, the second motor is fixedly provided at the rear end inside the main body of the equipment, the second motor output end is provided with a second linkage mechanism, two rotating shafts are rotatably provided at one end of the main body of the equipment near the connecting frame, multiple cams are fixedly provided on the outside of the two rotating shafts, and filters are slidably provided inside the two connecting frames.

[0009] Furthermore, the four sliders are rotatably disposed on opposite sides between the four connectors, and the multiple connectors are slidably disposed inside the main body of the device along with the exterior of the four sliders.

[0010] Furthermore, each of the connecting blocks has a second nozzle fixedly installed at its lower end, and one of the two bidirectional lead screws has its rear end fixedly installed at the output end of the first motor.

[0011] Furthermore, one of the two rotating shafts is fixedly mounted at the rear end of the second motor output end, and a handle is fixedly mounted at the front end of both connecting frames.

[0012] Furthermore, multiple springs are fixedly installed at the lower ends of both filters, and the lower ends of the multiple springs are respectively fixedly installed inside the lower ends of the two connecting frames, while the two connecting frames are slidably installed inside the main body of the device.

[0013] Furthermore, an inlet valve is fixedly installed at the front end of the main body of the equipment, and an outlet valve is fixedly installed at the end of the front end of the main body of the equipment away from the inlet valve.

[0014] Furthermore, a first conveyor belt is provided at the upper end of the main body of the equipment, and a second conveyor belt is provided at the lower end of the main body of the equipment. Multiple first nozzles are provided at both ends of the first and second conveyor belts. A flap is fixedly provided on the side of the main body of the equipment away from the first motor.

[0016] This utility model has the following beneficial effects:

[0017] 1. The screening and cleaning equipment proposed in this utility model allows for the adjustment of the distance between the second nozzles. A first motor drives a first linkage mechanism and a bidirectional lead screw to rotate, causing a slider to move the connecting piece in the opposite direction. This, in turn, causes the connecting block to slide inside the main body of the equipment, automatically changing the spacing between the second nozzles. This allows the equipment to be customized according to different sizes of tofu, ensuring optimal cleaning results, improving the applicability and flexibility of the equipment. Furthermore, automated operation replaces traditional manual selection and cleaning, significantly reducing labor requirements and improving work efficiency.

[0018] 2. The screening and cleaning equipment proposed in this utility model, when the second motor is running, causes the rotating shaft to rotate inside the main body of the equipment through the second linkage mechanism, and also drives multiple cams to rotate accordingly. During the rotation of the cams, the filter screen will be pushed, causing it to move up and down reciprocally inside the connecting frame, thereby ensuring the normal filtration function of the filter screen, reducing equipment failures caused by residue clogging the filter screen, extending the service life of the filter screen, and also reducing the frequency and cost of equipment maintenance.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-5One embodiment provided by this utility model:

[0029] A screening and cleaning device includes a main body 1. An adjustment mechanism 4 is provided inside the main body 1. The adjustment mechanism 4 includes two connecting frames 401 and four connecting parts 410. Multiple connecting blocks 408 are rotatably arranged on both sides of the four connecting parts 410. Two bidirectional lead screws 402 are rotatably arranged inside the main body 1. A first motor 13 is fixedly arranged at the rear end inside the main body 1. Two sliders 407 are threadedly connected to the two bidirectional lead screws 402. The four sliders 407 are rotatably arranged on opposite sides between the four connecting parts 410. The multiple connecting blocks 408 and the four sliders 407 are slidably arranged inside the main body 1. A second nozzle 409 is fixedly arranged at the lower end of the multiple connecting blocks 408. One of the two bidirectional lead screws 402 is fixedly arranged at the output end of the first motor 13. A first linkage mechanism 14 is provided at the output end of the first motor 13.

[0030] Specifically, when it is necessary to adjust the spacing between the second nozzles 409, the first motor 13 is started, driving the first linkage mechanism 14 and the bidirectional lead screw 402 to operate. The first linkage mechanism 14 consists of a synchronous belt and a synchronous pulley. Since the external thread of the bidirectional lead screw 402 is connected to the slider 407, when the bidirectional lead screw 402 rotates, the two sliders 407 will move in opposite directions along the bidirectional lead screw 402 inside the main body 1 of the equipment, causing the connecting piece 410 to drive the connecting block 408 to slide inside the main body 1 of the equipment. The sliding of the connecting block 408 will synchronously drive the second nozzles 409 at its lower end to move, thereby changing the spacing between the second nozzles 409, ensuring that the cleaning area can fully cover the tofu, effectively improving the cleaning efficiency. This allows the equipment to flexibly adjust the coverage of the cleaning area according to the size and shape of the tofu, adapting to different cleaning needs and improving the versatility and practicality of the equipment.

[0031] Reference Figures 1-6 The equipment body 1 has a second motor 15 fixedly installed at the rear end inside. The output end of the second motor 15 is provided with a second linkage mechanism 16. The equipment body 1 has two rotating shafts 404 rotatably installed at one end near the connecting frame 401. Multiple cams 406 are fixedly installed on the outside of each of the two rotating shafts 404. Filter screens 405 are slidably installed inside each of the two connecting frames 401. The rear end of one of the two rotating shafts 404 is fixedly installed at the output end of the second motor 15. Handles 403 are fixedly installed at the front end of each of the two connecting frames 401. Multiple springs 411 are fixedly installed at the lower end of each of the two filter screens 405. The lower ends of the multiple springs 411 are respectively fixedly installed at the lower end of the two connecting frames 401. The outside of the two connecting frames 401 is slidably installed inside the equipment body 1.

[0032] Specifically, when the second motor 15 operates, it activates the second linkage mechanism 16, causing the rotating shaft 404 to rotate inside the main body 1 of the equipment. The second linkage mechanism 16 consists of a synchronous belt and a synchronous pulley. When the rotating shaft 404 rotates, multiple cams 406 fixed externally also rotate. The cams 406 press the filter screen 405, causing the filter screen 405 to reciprocate up and down inside the connecting frame 401. During this process, the spring 411 is stretched and squeezed, thereby effectively preventing residue from clogging the filter screen 405, ensuring the continuous and stable operation of the screening process, reducing the frequency and cost of equipment maintenance, and improving production efficiency. When replacing the filter screen 405, it is only necessary to remove the filter screen 405 from the main body 1 through the handle 403, which is convenient to operate.

[0033] Reference Figures 1-3 A water inlet valve 2 is fixedly installed at the front end of the main body 1, and a water outlet valve 3 is fixedly installed at the end of the main body 1 away from the water inlet valve 2. A first conveyor belt 9 is installed at the upper end of the inside of the main body 1, and a second conveyor belt 10 is installed at the lower end of the inside of the main body 1. Multiple first nozzles 8 are installed at both ends of the first conveyor belt 9 and the second conveyor belt 10. A flap 11 is fixedly installed on the side of the inside of the main body 1 away from the first motor 13. A water pump 12 is fixedly installed at the rear end of the inside of the main body 1. A control valve 7 is installed at the output end of the water pump 12. A slide plate 6 is installed on the side of the main body 1 away from the water pump 12. A placement box 5 is installed on one side of the slide plate 6.

[0034] Specifically, during cleaning, the water inlet valve 2 is opened first, and water flows into the equipment body 1. The water flows through the second nozzle 409 and the first nozzle 8 above it, continuously injecting into the lower area inside the equipment body 1 until the upper end of the second conveyor belt 10 is filled with water. When the water pump 12 is started, it can transport the water at the lower end of the second conveyor belt 10 through the pipeline to the control valve 7 at the output end. Then, the water is sprayed out from the second nozzle 409 and the first nozzle 8 at the upper end of the first conveyor belt 9, so that the upper end of the first conveyor belt 9 is also gradually filled with water, realizing the reuse of water and reducing the waste of water resources. In addition, the surfaces of the first conveyor belt 9 and the second conveyor belt 10 are provided with holes. These holes facilitate the water to flow down and can discharge the sewage in the cleaning process in time, avoiding the accumulation of sewage on the conveyor belt, which helps to maintain a good cleaning environment and ensure the cleaning effect.

[0035] After the preparation work is completed, the tofu is placed on the upper end of the first conveyor belt 9, which will move the tofu toward the flip plate 11. During the movement of the tofu, the first nozzles 8 on both sides inside the main body 1 will perform preliminary cleaning on both sides of the tofu, and the water sprayed by the first nozzles 8 will form convection to reduce the crushing of the tofu. When the tofu moves to a specific position, the second nozzle 409 will clean the upper end of the tofu. When the tofu moves to the flip plate 11, it will stick to the surface of the flip plate 11 and then slide along the flip plate 11 toward the second conveyor belt 10 to flip the tofu. The second conveyor belt 10 continues to move the tofu. During this process, the first nozzles 8 and the second nozzles 409 will perform a second rinse on the tofu. Finally, the cleaned tofu slides into the placement box 5 through the slide plate 6. After the cleaning is completed, the water outlet valve 3 is opened to discharge the sewage inside the main body 1.

[0036] The first nozzle 8 and the second nozzle 409 enable multi-directional cleaning of the tofu, ensuring that all parts of the tofu are thoroughly cleaned, resulting in good cleaning effect and improving the quality of pre-processing in fermented bean curd production.

[0037] Working principle: In operation, first open the water inlet valve 2 to allow water to enter the main body 1 of the equipment. The water will continuously flow into the lower part of the main body 1 through the second nozzle 409 and the first nozzle 8 above it, thus filling the upper part of the second conveyor belt 10 with water. The water pump 12 starts, guiding the water from the lower part of the second conveyor belt 10 through its input end to the control valve 7 at its output end, and spraying it out from the second nozzle 409 and the first nozzle 8 at the upper end of the first conveyor belt 9, gradually filling the upper part of the first conveyor belt 9 with water. Simultaneously, place tofu on the upper part of the first conveyor belt 9, and then connect the first conveyor belt 9 with the second... When the conveyor belt 10 operates, the operation of the first conveyor belt 9 will move the tofu at its upper end toward the flip plate 11. When the tofu is moving, the first nozzles 8 on both sides inside the main body 1 will clean the sides of the tofu. When it reaches a certain position, the second nozzle 409 will clean its upper end. When the tofu moves onto the flip plate 11, it will adhere to its surface and then slide toward the second transmission belt, thereby turning the tofu over. The second transmission belt will drive the tofu to move, so that the first nozzles 8 and the second nozzles 409 will rinse it a second time. Finally, the tofu will enter the placement box 5 through the slide plate 6.

[0038] When it is necessary to adjust the spacing between the second nozzles 409, the first motor 13 is started, which drives the first linkage mechanism 14 and the bidirectional lead screw 402 to operate, thereby causing the slider 407 outside the bidirectional lead screw 402 to move in the opposite direction. The movement of the slider 407 will drive the connecting block 408 to slide inside the main body 1 through the connector 410. The sliding of the connecting block 408 will synchronously drive the second nozzles 409 at its lower end to move, thereby changing the spacing between the second nozzles 409 to ensure full coverage of the cleaning area.

[0039] When the second motor 15 is running, it will activate the second linkage mechanism 16, causing the rotating shaft 404 to rotate inside the main body 1 of the equipment. The rotation of the rotating shaft 404 will cause multiple cams 406 on its outside to rotate. The rotation of the cams 406 will periodically press the filter screen 405, causing it to move up and down inside the connecting frame 401, and stretching and squeezing the spring 411, thereby preventing the residue at its upper end from clogging the filter screen 405.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
