[0002] In traditional bean processing, impurity removal and washing are usually separate steps, requiring manual transfer of the sieved beans to washing equipment, which is inefficient and labor-intensive. Existing sieve equipment mostly uses single-layer screens, making it difficult to achieve multi-stage sorting; while washing equipment typically relies solely on mechanical stirring, resulting in limited cleaning effectiveness. Therefore, there is an urgent need for an automated device that can combine multi-stage sieve removal and washing. Utility Model Content

The equipment is equipped with a screening box and a cleaning tank. Soybean raw materials screened in the screening box are directly transported to the cleaning tank for washing. The impurity removal and cleaning processes are continuous, avoiding the need for manual handling of the soybean raw materials to the cleaning equipment after impurity removal, thus saving manpower and improving processing efficiency. The equipment uses two screens with different apertures to screen the soybean raw materials twice, improving the impurity removal efficiency. A rotating shaft drives the spiral blades to rotate, while air is injected into the cleaning tank through an air pipe, causing the material in the cleaning tank to tumble. The combination of mechanical and pneumatic forces enhances the stirring force, resulting in better cleaning and improved cleaning efficiency for the soybean raw materials.

A hopper is installed on the top of the screening box. A vertical rod is installed at each of the four corners of the screening box, and a spring column is installed at the top of each rod. A first screen and a second screen are respectively installed obliquely on the four vertical rods. The first screen has a plurality of screen holes (I) evenly distributed, and the second screen has a plurality of screen holes (II) evenly distributed. The diameter of the first screen holes is larger than that of the second screen holes. A vibrating motor is installed at the bottom of each screen. A discharge port (I) is provided on the side wall of the screening box corresponding to the end of the first screen. A collection box is installed on the side wall of the box corresponding to the first discharge port. A second discharge port is set on the side wall of the screening box corresponding to the end of the second screen. A guide plate is inclinedly set on the side wall of the screening box corresponding to the second discharge port. The guide plate overlaps the side wall of the washing box. An air pipe is spirally installed at the bottom of the washing box. One end of the air pipe passes through the side wall of the washing box and is connected to a blower. Several bubble nozzles are installed on the side wall of the air pipe. A rotating shaft is installed on the inner wall of the washing box. A servo motor is connected to one end of the rotating shaft. Spiral blades are set on the rotating shaft. A drain pipe is set on the side wall of the washing box. A solenoid valve is installed on the drain pipe.

[0006] Furthermore, each of the four corners of each screen has a through hole.
[0007] Furthermore, a receiving tray is installed inside the screening box.
[0008] Furthermore, a feed inlet is provided on the side wall of the cleaning tank corresponding to the position of the guide plate.

[0011] Furthermore, the controller is equipped with several operation buttons.
[0012] As can be seen from the above technical solution, this application provides a high-efficiency soybean impurity removal and cleaning linkage device for tofu production, including: a screening box and a cleaning box, which are installed on a base plate. A hopper is provided on the top of the screening box, and soybean raw materials enter the screening box through the hopper. A vertical rod is provided at each of the four corners of the screening box, and a spring column is installed on the top of each vertical rod. A first screen and a second screen are respectively installed obliquely on the four vertical rods. The two screens are sequentially installed and fixed on the four vertical rods through four through holes on each screen. The first screen is located above the second screen. The spring column enhances the stability of the screen and the vertical rod during vibration. A number of screen holes 1 are evenly arranged on the first screen, and a number of screen holes 2 are evenly arranged on the second screen. A vibration motor is installed at the bottom of each screen. A discharge port 1 is located on the side wall of the screening box, corresponding to the end of the first screen. A collection box is installed on the side wall of the screening box corresponding to the discharge port 1. A discharge port 2 is located on the side wall of the screening box, corresponding to the end of the second screen. A guide plate is inclinedly installed on the side wall of the screening box corresponding to the discharge port 2, and the guide plate overlaps the side wall of the washing box. Before the bean raw material enters the screening box, the controller starts two vibration motors, which drive the two screens to vibrate. The bean raw material enters the screening box and falls onto the first screen. The vibration of the first screen causes the small-sized bean raw material to fall through the first screen hole into the second screen below. Larger-sized impurities continue to travel along the inclined screen and enter the collection box from the discharge port 1. The vibration of the second screen causes the small-sized impurities in the bean raw material to fall through the second screen hole into the collection box below. In the feed tray, qualified bean raw materials continuously move along the second screen and are discharged from the second outlet. They are then guided into the washing tank via an inclined guide plate. After being screened in the screening box, the bean raw materials are directly transported to the washing tank for washing. The impurity removal and washing processes are continuous, avoiding the need for manual handling of the bean raw materials to the washing equipment for further washing after impurity removal, saving manpower and improving processing efficiency. Two screens with different apertures are used to screen the bean raw materials twice, improving the impurity removal efficiency. An air pipe is spirally installed at the bottom of the washing tank, with one end of the air pipe passing through the side wall of the washing tank and connected to a blower. Several bubble nozzles are installed on the side wall of the air pipe. A rotating shaft is installed on the inner wall of the washing tank, with one end connected to a servo motor. Spiral blades are installed on the rotating shaft before the screened bean raw materials enter the washing tank. The controller activates the blower and servo motor. The gas generated by the blower enters the air pipe and is released through the bubble nozzle, causing the water in the washing tank to churn, which in turn tumbles the material. The motor rotates, driving the shaft and spiral blades to agitate and transport the material in the washing tank. The combination of mechanical and pneumatic forces enhances the agitation, resulting in better cleaning and improved efficiency for the bean raw materials. A drain pipe with a solenoid valve is installed on the side wall of the washing tank. A discharge port is located on the side wall corresponding to the position of the shaft. After the bean raw materials are cleaned, the controller opens the solenoid valve on the drain pipe, allowing the water in the washing tank to drain out.The controller shuts down the blower, opens the sealing cover on the discharge port, and the motor drives the rotating shaft and spiral blades to transport the bean raw materials, which are then discharged through the discharge port. An external controller connects the screening box and washing box. The vibrating motor, servo motor, and blower are wired to the controller, and the solenoid valves are electrically connected to the controller. The controller controls the operating status of the vibrating motor, servo motor, blower, and solenoid valves, thereby ensuring the smooth progress of impurity removal and washing of the bean raw materials.
[0013] In summary, the beneficial effects of this application are as follows:
[0014] 1. The equipment is equipped with a screening box and a washing tank. The raw beans after screening in the screening box are transported to the washing tank for direct washing. The impurity removal and washing processes are continuous, avoiding the need for manual handling of the raw beans to the washing equipment after impurity removal, saving manpower and improving processing efficiency.
[0015] 2. The screening box is equipped with two screens with different apertures to screen the bean raw materials twice, thereby improving the efficiency of removing impurities from the bean raw materials.
[0016] 3. The washing tank is equipped with a rotating shaft and an air pipe. When the bean raw materials are washed in the washing tank, the rotating shaft drives the spiral blades to rotate and the air pipe injects gas into the washing tank, causing the materials in the washing tank to tumble. The combination of mechanical and pneumatic forces increases the stirring force, resulting in better washing effect and improving the washing efficiency of bean raw materials.

Detailed Implementation
[0023] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0024] As can be seen from the above technical solutions, see [link / reference]. Figures 1-3 .
[0025] Example 1:
[0026] This is a high-efficiency soybean cleaning and washing system for tofu production, comprising: a screening box 1 and a washing box 2, which are mounted on a base plate. A hopper 3 is located at the top of the screening box 1, through which soybean raw materials enter the screening box 1. Four uprights 4 are located at the four corners of the screening box 1, each topped with a spring column 5. A first screen 6 and a second screen 7 are respectively installed obliquely on the four uprights 4. The two screens are sequentially fixed to the four uprights 4 through four through-holes on each screen. The first screen 6 is positioned above the second screen 7. The spring columns 5 enhance the stability of the screens and uprights 4 during vibration. The first screen 6 has a number of uniformly distributed screen holes (I), and the second screen 7 has a number of uniformly distributed screen holes (II). The I screen holes have a larger diameter. The different aperture sizes of the sieve holes (second screen) are used to grade and screen the bean raw materials, thereby improving the screening effect. A vibrating motor is installed at the bottom of each sieve. A discharge port (first outlet) is located on the side wall of the screening box 1 corresponding to the end of the first sieve 6. A collection box is installed on the side wall of the screening box 1 corresponding to the discharge port (first outlet). A discharge port (second outlet) is located on the side wall of the screening box 1 corresponding to the end of the second sieve 7. A guide plate (9) is inclinedly installed on the side wall of the screening box 1 corresponding to the discharge port (second outlet). The guide plate (9) overlaps the side wall of the washing box 2. Before the bean raw materials enter the screening box 1, the controller 8 starts two vibrating motors, which drive the two sieves to vibrate. The bean raw materials enter the screening box 1 and fall onto the first sieve 6. The vibration of the first sieve 6 causes smaller bean raw materials to fall through the sieve hole (first outlet) below. On the second screen 7, larger impurities continue to travel along the inclined first screen and enter the collection box from the discharge port 1. The vibration of the second screen 7 causes smaller impurities in the bean raw material to fall through the screen holes 2 into the receiving tray below. Qualified bean raw material continues to travel along the second screen 7 and is discharged from the discharge port 2. It is then guided into the washing box 2 by the inclined guide plate 9. The bean raw material after being screened by the screening box 1 is transported to the washing tank for direct washing. The impurity removal and washing processes are continuous, avoiding the need for manual handling to the washing equipment after impurity removal, saving manpower and improving processing efficiency. The bean raw material is screened twice using two screens with different apertures, improving the impurity removal efficiency. An air pipe 10 is coiled at the bottom of the washing box 2. A blower 16 is connected to the side wall of the washing tank 2 at one end. Several bubble nozzles 11 are installed on the side wall of the air pipe 10. A rotating shaft 12 is installed on the inner wall of the washing tank 2. A servo motor 14 is connected to one end of the rotating shaft 12. Spiral blades 13 are installed on the rotating shaft 12. Before the screened bean raw materials enter the washing tank 2, the controller 8 controls the blower 16 and the servo motor 14 to turn on. The gas generated by the blower 16 enters the air pipe 10 and is released by the bubble nozzles 11, causing the water in the washing tank to tumble, which in turn drives the material to tumble. The rotation of the motor drives the rotating shaft 12 and the spiral blades 13 to rotate, stirring and conveying the material in the washing tank 2. The gas injected into the washing tank through the air pipe 10 and the rotation of the spiral blades 13 driven by the rotating shaft 12 cause the material in the washing tank to tumble.Combining mechanical and pneumatic techniques enhances the stirring force, resulting in better cleaning effects and improved cleaning efficiency for the soybean raw materials. A drain pipe with a solenoid valve is installed on the side wall of the cleaning tank 2. A discharge port 15 is located on the side wall of the cleaning tank 2 corresponding to the position of the rotating shaft 12. After the soybean raw materials are cleaned, the controller 8 opens the solenoid valve on the drain pipe, allowing the water in the cleaning tank 2 to drain out. After draining, the controller 8 shuts off the blower 16, opens the sealing cover on the discharge port 15, and the motor drives the rotating shaft 12 and the spiral blades 13 to rotate and transport the soybean raw materials, allowing them to be discharged through the discharge port 15.
[0027] The screening box 1 and the washing box 2 are connected to a controller 8. The vibration motor, servo motor 14 and blower 16 are connected to the controller 8. The solenoid valve is electrically connected to the controller 8. The controller 8 controls the working status of the vibration motor, servo motor 14, blower 16 and solenoid valve, thereby ensuring the smooth progress of the impurity removal and washing of the bean raw materials.
[0028] In a preferred embodiment, each of the four corners of the screen is provided with a through hole, and the four through holes fix the screen to the four uprights 4 so that it can screen the bean raw materials.
[0029] In a preferred embodiment, a receiving tray is provided inside the screening box 1. The receiving tray collects small-diameter impurities screened by the second screen hole. The receiving tray can be pulled out and processed later.
[0030] In a preferred embodiment, a feed inlet is provided on the side wall of the washing tank 2 corresponding to the position of the guide plate. The guide plate 9 overlaps the feed inlet of the washing tank to introduce the bean raw material into the washing tank 2.
[0031] In a preferred embodiment, the discharge port 15 is provided with a sealing cover, which ensures the sealing of the discharge port 15 of the cleaning tank 2 and prevents it from leaking water.
[0032] In a preferred embodiment, a filter screen is provided at the location where the drain pipe is connected to the side wall of the washing tank 2. When the washing tank 2 is drained, the filter screen filters the bean raw material to prevent the bean raw material from being discharged during drainage.
[0033] In a preferred embodiment, the controller 8 is provided with several operation buttons, each of which controls the working status of the various devices.
