Description

Technical Field

[0001] This utility model relates to the field of tofu production technology, specifically to a wastewater recycling and treatment device for tofu production and processing. Background Technology

[0002] In the production process of soy products, a large amount of water is usually used to continuously rinse and soak soybeans. The wastewater generated after the production of soy products contains a lot of impurities, so wastewater recycling and treatment devices are needed to recycle and treat the production wastewater.

[0003] As disclosed in CN216571845U, a wastewater recycling and treatment device for tofu production includes a water tank. An inlet pipe is installed on one side of the top of the water tank. A support plate is installed on the inner wall of the water tank near the inlet pipe. A rotating shaft is rotatably connected between the support plate and one side of the inner wall of the water tank. Multiple blades are installed on the circumference of the outer surface of the rotating shaft. The beneficial effects of this invention are: by forming a pusher plate with the rotating plate and the rectangular frame, impurities accumulated on the partition are pushed and squeezed, and the filtered wastewater is pushed into the water tank for collection, resulting in smaller impurities and preventing them from clogging the filter holes on the partition.

[0004] Although the aforementioned patent relies on the impact force of the incoming water flow on the blades to achieve cleaning, although tofu wastewater contains impurities, its flow rate and pressure are usually low and unstable. Once the filter residue begins to accumulate on the baffle, the force required to push the rectangular frame will be much greater than the torque generated by the water flow. This can easily cause the shaft to fail to start or become stuck due to insufficient torque, paralyzing the entire self-cleaning mechanism, and ultimately the filter holes will still be clogged. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater recycling and treatment device for tofu production and processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A wastewater recycling and treatment device for tofu production and processing, comprising: A processing tank, with a vertical partition fixedly connected in the middle, and a filter plate movably mounted on the upper end of the processing tank via a moving mechanism; A frame is located on the left side of the filter plate, and a spraying mechanism is provided between the frame and the treatment tank; A flipping mechanism is provided between the filter plate and the moving mechanism.

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.

[0013] like Figure 1-4 As shown, this utility model provides a technical solution: A wastewater recycling and treatment device for tofu production includes a treatment tank 1, with a vertical partition 2 fixedly connected to its middle. A filter plate 3 is movably mounted on the upper end of the treatment tank 1 via a moving mechanism. The moving mechanism includes a lead screw 5 rotatably connected to the left top end of the treatment tank 1 via bearings, and a guide rod 6 fixedly connected to the right top end of the treatment tank 1. A slider 7 is threaded onto the lead screw 5, and a guide block 8 is slidably fitted onto the guide rod 6. The two ends of the filter plate 3 are rotatably connected to the slider 7 and the guide block 8 respectively via rotating shafts. A motor 9 is fixedly connected to the upper left corner of the front of the treatment tank 1, and the output shaft of the motor 9 is fixedly connected to the lead screw 5. A frame 4 is located to the left of the filter plate 3. A spraying mechanism is provided between the frame 4 and the treatment tank 1. The spraying mechanism includes a slurry pump 10 fixedly connected to the back of the top of the frame 4, and a spray pipe 11 horizontally arranged on the front of the top of the frame 4. The frame 4 is fixedly connected to the left top end of the slider 7, and the input end of the spray pipe 11 is connected to the slurry pump 10. The output end is connected to the filter plate 3. The spraying mechanism also includes a clean water tank 12 located on one side of the front of the partition plate 2 and a wastewater tank 13 located on the back of the partition plate 2. The bottom end of the wastewater tank 13 near the slurry pump 10 is fixedly connected to a slurry pump pipe 14. The output end of the slurry pump pipe 14 is connected to a bellows pipe 16 and a clean water pipe 17 respectively through a reversing valve 15. The output end of the bellows pipe 16 is connected to the input end of the slurry pump 10. A flipping mechanism is provided between the filter plate 3 and the moving mechanism. The flipping mechanism includes... Positioning blocks 18 are fixedly connected to the upper and lower ends of the middle of both sides of the filter plate 3. A threaded hole 19 is opened through the middle of the positioning block 18. The upper and lower ends of the slider 7 and the guide block 8 are fixedly connected to the middle of the middle of the upper and lower ends. The fixing seat 20 and the positioning block 18 are fixedly connected by the locking screw 21. A drain outlet 22 is fixedly connected to the bottom of the front of the treatment tank 1. The drain outlet 22 is connected to the clean water tank 12. A water inlet pipe 23 is fixedly connected to the upper back of the treatment tank 1. The water inlet pipe 23 is connected to the wastewater tank 13. In this embodiment, by using the filter plate 3 in conjunction with the flipping mechanism, the filter plate can be quickly flipped 180° and automatically cleaned, which solves the problem of the complicated and cumbersome cleaning process of traditional filter devices, significantly improves maintenance efficiency and reduces the intensity of manual operation.

[0014] Furthermore, the locking screw 21, the positioning block 18 and the fixed seat 20 work together to form a mechanical connection structure that can be quickly released and locked, which solves the technical problem of complicated disassembly procedures required for filter plate maintenance and realizes convenient maintenance of the equipment.

[0015] Working principle: Wastewater enters the wastewater tank 13 through the inlet pipe 23. At this time, the filter plate 3 is located above the clean water tank 12. The slurry pump 10 draws wastewater from the wastewater tank 13 through the slurry pumping pipe 14, and delivers it to the spray pipe 11 through the reversing valve 15 and the bellows 16, spraying it downwards. The wastewater is filtered by the filter plate 3 below and flows into the clean water tank 12. Solid impurities are trapped on the surface of the filter plate 3. When the filter plate 3 needs to be cleaned, the motor 9 is started to drive the lead screw 5 to rotate, driving the slider 7 and the guide block 8 to move to the right, thereby moving the filter plate 3 along with the frame 4 to the top of the wastewater tank 13. Then, the operator loosens the locking screw 21 to release the positioning block 18 from the fixed seat 20, and controls the filter plate 3 to rotate 180° around the axis to set it up. The surface filter cake is poured into the waste residue collection area of ​​the wastewater tank 13; then the filter plate 21 is fixed in the new position after being flipped using the locking screw 21; then the clean water pipe 17 is connected to the corrugated pipe 16 by operating the reversing valve 15, and the slurry pump 10 draws clean water from the clean water tank 12 and sprays it downward through the spray pipe 11. If it is necessary to increase the rinsing area, a sprayer can be installed at the output end of the spray pipe 11 to backwash the filter plate 3 that has been flipped below, remove residual impurities, and the wastewater after rinsing falls back into the wastewater tank 13; after the backwashing is completed, the motor 9 drives the filter plate 3 to move to the left and reset to the top of the clean water tank 12, ready to enter the next filtration cycle, while the filtered clean water in the clean water tank 12 is discharged and recycled through the drain outlet 22.

[0016] It should be noted that in the specific implementation of this technical solution, the control methods for motor 9 and slurry pump 10 can be configured with conventional PLC controllers, relay control cabinets, or single-chip microcomputer control systems found in existing technologies. Although these automatic control units are not described in detail in the technical solution, they are supporting components that can be conventionally selected by those skilled in the art based on actual automation needs. Their selection and wiring control logic follow well-known technologies in this field and do not affect the implementation of the core innovation of this solution. In practical applications, this control system is mainly used to coordinate the forward and reverse rotation of the motor, the start and stop of the slurry pump, and the switching of the reversing valve. However, its specific type and connection method can be adjusted according to production requirements, all of which fall within the reasonable extension scope of this technical solution.

[0017] It should be further noted that conventional float level sensors, ultrasonic level gauges, or hydrostatic level transmitters, as used in existing technologies, can be installed inside the wastewater tank 13 and the clean water tank 12. Although these level detection elements are not described in detail in the technical solution, they are sensing devices that can be conventionally selected by those skilled in the art based on actual level monitoring and linkage control needs. Their installation and signal feedback follow well-known techniques in this field and do not affect the implementation of the core innovation of this solution. In practical applications, the level sensor is mainly used to realize high-level alarms, automatic pump start / stop, or system linkage protection, but its specific type and installation location can be adjusted according to the tank structure, all of which fall within the reasonable extension range of this technical solution.

[0018] It should be further noted that conventional bellows-type telescopic dust covers, folding protective covers, or accordion-type protective covers, as well as other existing technologies, can be installed on the exterior of the lead screw 5 and guide rod 6. Although these protective devices are not described in detail in the technical solution, they are standard accessories that can be routinely selected by those skilled in the art based on the actual needs of transmission components for contamination prevention and extended lifespan. Their fixing and telescopic functions follow well-known technologies in this field and do not affect the implementation of the core innovation of this solution. In practical applications, the telescopic dust cover is mainly used to isolate wastewater vapor and solid impurities to protect precision transmission components, but its specific material and sealing method can be adjusted according to the severity of the environment, all of which fall within the reasonable extension range of this technical solution.

[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
