Description

Technical Field

[0001] This invention relates to the field of water washing and purification, specifically to a water washing and purification component for separating starch from wheat flour and its usage method. Background Technology

[0002] Purification refers to the process of separating impurities from a mixture to increase its purity. As an important chemical method, purification plays a crucial role not only in chemical research but also in chemical production. Many important chemical research projects and chemical production processes are based on purification.

[0003] For example, patent document CN216395393U discloses a water washing and purification system, including a housing with a feeding hopper at the top, connecting frames on the lower side walls of the housing, a base plate on the bottom wall of the two connecting frames, a collection box above the base plate, and a groove between the center of the upper and lower side walls of the housing. A first filtration mechanism is located above the groove, and a second filtration mechanism is located below the groove. This invention, with its well-designed guiding feeding mechanism, achieves high feeding efficiency during actual feeding operations. Furthermore, its well-designed water washing and filtration purification mechanisms also result in high efficiency during water washing and purification operations, and facilitate disassembly. Additionally, the well-designed collection mechanism makes it convenient to collect the purified liquid after water washing.

[0004] For example, the wheat starch washing and purification process disclosed in CN111171165A involves the following steps: First, wheat flour and fresh water are mixed to form a paste; the paste is then centrifuged in a three-phase horizontal screw centrifuge to obtain a mixture of gluten powder and B starch, A starch, and pentosan-based process water; the gluten powder and B starch mixture, A starch, and pentosan-based process water are then further separated to finally obtain fiber powder, gluten powder, B starch, and A starch. The above invention first uses a three-phase horizontal screw centrifuge to centrifuge the paste. After the initial centrifugation, the gluten powder and B starch mixture, A starch, and pentosan-based process water require further separation to fully purify the various substances in the wheat starch, thus ensuring sufficient recycling in the wheat starch purification process and guaranteeing complete purification of the wheat starch.

[0005] However, the aforementioned patent documents still have the following shortcomings in practical application:

[0006] Before washing, wheat flour cannot effectively filter impurities, which may result in the presence of certain impurities in the wheat flour, affecting its quality and consequently the efficiency of the washing process. Summary of the Invention

[0007] The purpose of this invention is to provide a water washing and purification component for separating starch from wheat flour and a method for using it, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a water washing and purification component for separating starch from wheat flour, comprising a base, a water washing tank provided on the upper surface of the base, and a screening component for screening wheat flour provided on the upper end of the water washing tank;

[0009] The screening assembly includes a screening box and a dual-axis motor. The left output end of the dual-axis motor is provided with an eccentric block via a pin. The screening box is slidably connected to the washing tank. A spring damper is provided in the middle of the rear end of the screening box. A screen is provided in the middle of the inner wall of the screening box. A reciprocating screw is rotatably connected to the upper rear end of the screening box. A displacement rod is threadedly connected to the reciprocating screw. A turntable is rotatably connected to the lower end of the displacement rod via a pin. A swing rod is rotatably connected to the upper side of the front end face of the turntable via a pin. A flipping plate is provided on the lower end face of the swing rod.

[0010] The washing tank is also equipped with a stirring assembly, which includes a stirring shaft, stirring blades on both the left and right sides of the stirring shaft, and brush plates at both ends of the stirring blades.

[0011] A slider is provided on the bottom side of the screening box away from the stirring shaft. The slider extends into the screening box and is connected to one end of the screen. A limiting component is provided below the screen to prevent the screen from falling downward. A pressure sensor is provided on the brush plate to detect the pressure value of the washing tank on the brush plate. Telescopic components are provided in both the eccentric block and the first connecting rod to control the extension and retraction of the eccentric block and the first connecting rod.

[0012] This invention uses a pressure sensor on a brush plate to monitor the washing of wheat flour in a washing tank. If the pressure is less than a preset value, it indicates that the screen is clogged. By controlling the telescopic components on the eccentric block and the first connecting rod, the brush plate and the slider come into contact, pushing the slider to cause the screen to collide with the flipping plate, shaking off the wheat flour clogged on the screen. When the pressure is greater than the preset value, it indicates that the wheat flour content is too high. By controlling the telescopic components on the first connecting rod to extend, the centrifugal force on the brush plate increases synchronously, thereby improving the brush plate's scraping effect on the wheat flour adsorbed on the side wall of the washing tank. This effectively removes the wheat flour adsorbed on the side wall of the washing tank and allows for thorough washing, avoiding the problem of incomplete washing of wheat flour due to a wheat flour to water mixing ratio lower than the preset value.

[0013] Preferably, the left output end of the dual-axis motor is provided with an eccentric block and a rotating bevel gear via a pin shaft. A pressing plate is provided in the middle of the lower side of the right end face of the screening box. The eccentric block and the rotating bevel gear are both rotatably connected to a fixing plate via a pin shaft. The lower end face of the fixing plate is fixedly connected to the washing tank. A grooved cylinder is rotatably connected to the right end of the fixing plate. A driven bevel gear is sleeved and provided at the lower end of the grooved cylinder. The driven bevel gear meshes with the rotating bevel gear. A protruding rod is inserted into and slidably connected to the grooved cylinder. A first bevel gear is sleeved and provided at the upper end of the protruding rod. The protruding rod is rotatably connected to the screening box. A second bevel gear is sleeved and provided at the right end of the reciprocating screw. The second bevel gear meshes with the first bevel gear.

[0014] Preferably, a fixed rod is slidably connected to the upper end of the displacement rod, and both ends of the fixed rod are fixedly connected to the screening box.

[0015] Preferably, a second gear is provided at the connection between the turntable and the displacement rod via a pin, and a second rack is provided on the upper side of the rear end face of the inner cavity wall of the screening box, with the second rack meshing with the second gear.

[0016] Preferably, the right output end of the dual-shaft motor is provided with a second connecting rod via a pin, the upper right end of the second connecting rod is rotatably connected to a first connecting rod via a pin, the lower right end of the first connecting rod is rotatably connected to an L-shaped block via a pin, the middle left end of the L-shaped block is slidably connected to a limit rod, the lower end face of the limit rod is fixedly connected to the washing tank, the upper end of the stirring shaft is sleeved with and provided with a driving bevel gear, the right end of the L-shaped block is rotatably connected to a speed bevel gear and a first gear via a pin, and the middle upper end face of the washing tank is provided with a first rack, the first rack and the first gear mesh with each other.

[0017] Preferably, a rectangular plate is provided at the end of the stirring blade away from the stirring shaft, and sliding columns are slidably connected to both the upper and lower ends of the rectangular plate. Brush plates are provided on the opposite ends of the sliding columns on the left and right sides. Springs are sleeved on the sliding columns, and the two ends of the springs are fixedly connected to the rectangular plate and the sliding columns, respectively.

[0018] Preferably, a water tank is provided in the middle of the rear side of the upper end face of the washing tank, a water pump is connected to the middle of the rear end of the water tank, a hose is connected to the water outlet of the water pump, the hose passes through and is slidably connected to the washing tank, an annular pipe is connected to the lower end of the hose, an L-shaped plate is provided in the middle of the upper right side of the annular pipe, and the left end of the L-shaped plate is fixedly connected to the stirring shaft.

[0019] Preferably, a nozzle is provided at the lower end of the annular tube.

[0020] Preferably, a liquid outlet pipe is provided at the lower middle part of the washing tank, and a valve is provided on the liquid outlet pipe.

[0021] A method for using a water washing and purification component for separating starch from wheat flour includes the following specific steps:

[0022] S1. Add wheat flour to the screening box and start the dual-shaft motor. The dual-shaft motor drives the eccentric block to rotate, so that the eccentric block continuously squeezes the extrusion plate, causing the screening box to slide upward and return to its original position under the action of the spring damper. This causes the screening box to vibrate, screening the wheat flour and filtering out impurities in the wheat flour.

[0023] S2. Simultaneously, the rotating bevel gear and the driven bevel gear work together to make the grooved cylinder and the convex rod rotate at the same time, and the convex rod slides relative to the grooved cylinder, so that the first bevel gear and the second bevel gear rotate continuously, causing the reciprocating screw to rotate, and the displacement rod to move back and forth. When the displacement rod moves, the second gear rotates under the action of the second rack, which makes the turntable rotate, and the flipping plate moves left and right while also oscillating, turning over the wheat flour to avoid the accumulation of wheat flour and affecting the screening efficiency.

[0024] S3. After the wheat flour enters the washing tank, the water pump is started. The water pump draws water from the tank, which is then routed through a hose to the annular tube and sprayed from the nozzle. Simultaneously, the output of the dual-shaft motor on the right side causes the second and first connecting rods to rotate, making the L-shaped block slide back and forth on the limit rod. This causes the first gear to rotate under the action of the first rack, and the stirring shaft to move up and down and rotate back and forth under the action of the speed bevel gear and the drive bevel gear. This causes the annular tube to rotate back and forth, expanding the spray range of the water flow and making it more uniform. Then, the stirring blades move up and down, expanding the longitudinal stirring range, and the reciprocating rotation makes the wheat flour move more vigorously, thus uniformly stirring the wheat flour and water for washing. At the same time, under the action of the spring, the brush plate fits into the inside of the washing tank, scraping off the wheat flour adhering to the inner wall of the cavity to prevent it from sticking.

[0025] S4. After rinsing with water, open the drain pipe to discharge the liquid.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. In this invention, wheat flour is added to the screening box, and a dual-shaft motor is started simultaneously. The dual-shaft motor drives the eccentric block to rotate, causing the eccentric block to continuously squeeze the extrusion plate, making the screening box slide upwards. Under the action of the spring damper, it returns to its original position, thus causing the screening box to vibrate and screen the wheat flour, filtering out impurities. Simultaneously, the rotating bevel gear and the driven bevel gear work together to make the grooved cylinder and the protruding rod rotate at the same time, and the protruding rod slides relative to the grooved cylinder, causing the first bevel gear and the second bevel gear to rotate continuously, causing the reciprocating screw to rotate, and causing the displacement rod to move back and forth. When the displacement rod moves, the second gear rotates under the action of the second rack, which makes the turntable rotate. The pin shaft drives the swing rod to slide on the grooved block, causing the flipping plate to move left and right while swinging, turning the wheat flour, avoiding the accumulation of wheat flour and affecting the screening efficiency. Thus, it can achieve a highly efficient impurity filtration effect on the wheat flour to be washed, ensuring the quality of the wheat flour and avoiding the situation where impurities in the wheat flour affect the washing efficiency.

[0028] 2. In this invention, after wheat flour enters the washing tank, the water pump is started. The water pump draws water from the tank, which flows through a hose to the annular tube and is sprayed from the nozzle. Simultaneously, the output of the dual-shaft motor on the right side causes the second and first connecting rods to rotate, making the L-shaped block slide back and forth on the limiting rod. This causes the first gear to rotate under the action of the first rack, and the stirring shaft to move up and down and rotate back and forth under the action of the rotating bevel gear and the driving bevel gear. This causes the annular tube to rotate back and forth, expanding the spray range of the water flow and making it more uniform. Then, the vertical movement of the stirring blades expands the longitudinal stirring range, and the reciprocating rotation makes the wheat flour move more vigorously, thus uniformly stirring the wheat flour and water for washing. At the same time, under the action of the spring, the brush plate fits into the inside of the washing tank, scraping off the wheat flour adhering to the inner wall of the tank to prevent adhesion. After washing, the outlet pipe is opened to discharge the water. This achieves a uniform washing and purification effect on the wheat flour, improving the washing efficiency of the wheat flour.

Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0043] Example 1

[0044] Please see Figure 1-10 The present invention provides a technical solution:

[0045] A water washing and purification component for separating starch from wheat flour includes a base 2, a water washing tank 1 on the upper surface of the base 2, and a screening component for screening wheat flour on the upper end of the water washing tank 1.

[0046] The screening assembly includes a screening box 22 and a dual-axis motor 14. The screening box 22 is slidably connected to the washing tank 1. A spring damper 21 is provided in the middle of the rear end of the screening box 22. A screen 27 is provided in the middle of the inner wall of the screening box 22. A reciprocating screw 25 is rotatably connected to the upper rear end of the screening box 22. A displacement rod 45 is threadedly connected to the reciprocating screw 25. A turntable 31 is rotatably connected to the lower end of the displacement rod 45 through a pin. A swing rod 32 is rotatably connected to the upper side of the front end face of the turntable 31 through a pin. A flipping plate 30 is provided on the lower end face of the swing rod 32.

[0047] The washing tank 1 is also equipped with a stirring assembly, which includes a stirring shaft 5, and stirring blades 37 are provided on both the left and right sides of the stirring shaft 5.

[0048] In this embodiment, as Figures 1-5 As shown, the left output end of the dual-axis motor 14 is provided with an eccentric block 17 and a rotating bevel gear 19 via a pin. The middle of the lower side of the right end face of the screening box 22 is provided with a pressing plate 18. The eccentric block 17 and the rotating bevel gear 19 are both rotatably connected to a fixing plate 16 via a pin. The lower end face of the fixing plate 16 is fixedly connected to the washing tank 1. The right end of the fixing plate 16 is rotatably connected to a grooved cylinder 15. The lower end of the grooved cylinder 15 is fitted with and provided with a driven bevel gear 20. The driven bevel gear 20 and the rotating bevel gear 19 mesh with each other. The grooved cylinder 15 is inserted into and slidably connected with a protrusion rod 42. The upper end of the protrusion rod 42 is fitted with and provided with a first bevel gear 23. The protrusion rod 42 is rotatably connected to the screening box 22. The right end of the reciprocating screw 25 is fitted with and provided with a second bevel gear 24. The second bevel gear 24 and the first bevel gear 23 mesh with each other.

[0049] A fixed rod 26 is slidably connected to the upper end of the displacement rod 45, and both ends of the fixed rod 26 are fixedly connected to the screening box 22.

[0050] A second gear 29 is provided at the connection between the turntable 31 and the displacement rod 45 via a pin, and a second rack 28 is provided on the upper side of the rear end face of the inner cavity wall of the screening box 22. The second rack 28 and the second gear 29 mesh with each other.

[0051] In use, wheat flour is added to the screening box 22, and the dual-shaft motor 14 is started simultaneously. The dual-shaft motor 14 drives the eccentric block 17 to rotate, causing the eccentric block 17 to continuously squeeze the extrusion plate 18, making the screening box 22 slide upwards. Under the action of the spring damper 21, it returns to its original position, thus causing the screening box 22 to vibrate and screen the wheat flour, filtering out impurities. At the same time, the rotating bevel gear 19 and the driven bevel gear 20 work together to make the grooved cylinder 15 and the protruding rod 42 rotate simultaneously, and the protruding rod 42 slides relative to the grooved cylinder 15, thus making the first... The first bevel gear 23 and the second bevel gear 24 rotate continuously, causing the reciprocating screw 25 to rotate, which in turn causes the displacement rod 45 to move back and forth. When the displacement rod 45 moves, the second gear 29 rotates under the action of the second rack 28, which in turn causes the turntable 31 to rotate. This causes the flipping plate 30 to move horizontally and horizontally while also oscillating, thus turning over the wheat flour and preventing the accumulation of wheat flour from affecting the screening efficiency. This achieves a highly efficient impurity filtration effect on the wheat flour to be washed, ensuring the quality of the wheat flour and preventing impurities in the wheat flour from affecting the washing efficiency.

[0052] In this embodiment, as Figure 2 , Figure 6-10 As shown, the right output end of the dual-shaft motor 14 is connected to the second connecting rod 13 via a pin. The upper right end of the second connecting rod 13 is connected to the first connecting rod 12 via a pin. The lower right end of the first connecting rod 12 is connected to the L-shaped block 11 via a pin. The L-shaped block 11 is provided with a sliding groove that matches the pin. The middle left end of the L-shaped block 11 is slidably connected to the limiting rod 10. The lower end face of the limiting rod 10 is fixedly connected to the washing tank 1. The upper end of the stirring shaft 5 is fitted with and provided with the driving bevel gear 9. The right end of the L-shaped block 11 is rotatably connected to the rotational bevel gear 8 and the first gear 7 via a pin. The middle upper end face of the washing tank 1 is provided with the first rack 6, and the first rack 6 and the first gear 7 mesh with each other.

[0053] A rectangular plate 38 is provided at the end of the stirring blade 37 away from the stirring shaft 5. Sliding columns 39 are slidably connected to both the upper and lower ends of the rectangular plate 38. Brush plates 41 are provided on the ends of the sliding columns 39 on the left and right sides that are far apart from each other. Springs 40 are sleeved on the sliding columns 39. The two ends of the springs 40 are fixedly connected to the rectangular plate 38 and the sliding columns 39 respectively.

[0054] A water tank 3 is provided in the middle of the rear side of the upper end of the washing tank 1. A water pump 43 is connected to the middle of the rear end of the water tank 3. A hose 44 is connected to the water outlet of the water pump 43. The hose 44 passes through and is slidably connected to the washing tank 1. An annular pipe 35 is connected to the lower end of the hose 44. An L-shaped plate 34 is provided in the middle of the upper right side of the annular pipe 35. The left end of the L-shaped plate 34 is fixedly connected to the stirring shaft 5.

[0055] A nozzle 36 is provided at the lower end of the annular tube 35.

[0056] A liquid outlet pipe 4 is provided at the lower middle part of the water washing tank 1, and a valve is provided on the liquid outlet pipe 4.

[0057] In use, wheat flour enters the washing tank 1, then the water pump 43 is started. The water pump 43 draws water from the water tank 3, which flows through the hose 44 to the annular tube 35 and is sprayed out from the nozzle 36. Simultaneously, under the action of the output end on the right side of the dual-shaft motor 14, the second connecting rod 13 and the first connecting rod 12 rotate, causing the L-shaped block 11 to slide back and forth on the limiting rod 10. This causes the first gear 7 to rotate under the action of the first rack 6, and under the action of the rotational bevel gear 8 and the driving bevel gear 9, the stirring shaft 5 moves up and down and rotates back and forth, thus causing the annular tube 35 to rotate back and forth. The spray range of the water flow is expanded, making it more uniform. Then, under the action of the vertical movement of the stirring blades 37, the longitudinal stirring range is expanded, and the reciprocating rotation makes the wheat flour move more vigorously, so that the wheat flour and water can be evenly stirred and washed. At the same time, under the action of the spring 40, the brush plate 41 is made to fit against the inside of the washing tank 1, scraping off the wheat flour adhering to the inner wall of the tank and preventing it from sticking. After the washing is completed, the liquid outlet pipe 4 is opened to discharge the water. This can achieve a uniform washing and purification effect on the wheat flour and improve the washing efficiency of the wheat flour.

[0058] A method for using a water washing and purification component for separating starch from wheat flour includes the following specific steps:

[0059] S1. Add wheat flour to the screening box 22 and start the dual-shaft motor 14. The dual-shaft motor 14 drives the eccentric block 17 to rotate, so that the eccentric block 17 continuously squeezes the extrusion plate 18, causing the screening box 22 to slide upward and return to its original position under the action of the spring damper 21. This causes the screening box 22 to vibrate, screening the wheat flour and filtering out impurities in the wheat flour.

[0060] S2. Simultaneously, the rotating bevel gear 19 and the driven bevel gear 20 work together to make the grooved cylinder 15 and the protruding rod 42 rotate at the same time, and the protruding rod 42 slides relative to the grooved cylinder 15, so that the first bevel gear 23 and the second bevel gear 24 rotate continuously, causing the reciprocating screw 25 to rotate, and causing the displacement rod 45 to move back and forth. When the displacement rod 45 moves, the second gear 29 rotates under the action of the second rack 28, which makes the turntable 31 rotate, and the flipping plate 30 moves left and right while also oscillating, turning over the wheat flour to avoid the accumulation of wheat flour and affecting the screening efficiency.

[0061] S3. After the wheat flour enters the washing tank 1, the water pump 43 is started. The water pump 43 draws water from the water tank 3, which is then sent through the hose 44 to the annular tube 35 and sprayed out from the nozzle 36. At the same time, the second connecting rod 13 and the first connecting rod 12 are rotated by the output end of the dual-shaft motor 14, causing the L-shaped block 11 to slide back and forth on the limit rod 10. This causes the first gear 7 to rotate under the action of the first rack 6. Under the action of the rotational bevel gear 8 and the driving bevel gear 9, the stirring shaft 5 moves up and down and rotates back and forth, causing the annular tube 35 to rotate back and forth, expanding the spray range of the water flow and making it more uniform. Then, under the action of the up and down movement of the stirring blade 37, the longitudinal stirring range is expanded, and under the action of the reciprocating rotation, the movement of the wheat flour is made more intense, so that the wheat flour and water can be evenly stirred and washed. At the same time, under the action of the spring 40, the brush plate 41 is made to fit against the inside of the washing tank 1 to scrape off the wheat flour adhering to its inner wall and prevent it from sticking.

[0062] S4. After rinsing with water, open the outlet pipe 4 to drain the liquid.

[0063] Working principle of this invention: During use, wheat flour is added to the screening box 22, and the dual-shaft motor 14 is started simultaneously. The dual-shaft motor 14 drives the eccentric block 17 to rotate, causing the eccentric block 17 to continuously press the extrusion plate 18, making the screening box 22 slide upwards. Under the action of the spring damper 21, it returns to its original position, thus causing the screening box 22 to vibrate and screen the wheat flour, filtering out impurities. Simultaneously, the rotating bevel gear 19 and the driven bevel gear 20 work together to cause the grooved cylinder 15 and the protruding rod 42 to rotate simultaneously. The protruding rod 42 slides relative to the grooved cylinder 15, causing the first bevel gear 23 and the second bevel gear 24 to rotate continuously, causing the reciprocating screw 25 to rotate, and the displacement rod 45 to move left and right back and forth. When the displacement rod 45 moves, the second gear 29 rotates under the action of the second rack 28, causing the turntable 31 to rotate. This causes the turning plate 30 to move left and right while also oscillating, turning over the wheat flour and preventing accumulation that would affect screening efficiency. The wheat flour then enters the water... After washing tank 1, water pump 43 is started. Water pump 43 draws water out of water tank 3, which flows through hose 44 to annular pipe 35 and is sprayed out from nozzle 36. At the same time, under the action of the right output end of dual-shaft motor 14, the second connecting rod 13 and the first connecting rod 12 rotate, causing L-shaped block 11 to slide back and forth on limit rod 10. This causes the first gear 7 to rotate under the action of first rack 6, and under the action of rotational bevel gear 8 and driving bevel gear 9, the stirring shaft 5 moves up and down and rotates back and forth. The reciprocating rotation of the annular tube 35 expands the spray range of the water flow, making it more uniform. Then, under the action of the vertical translation of the stirring blade 37, the longitudinal stirring range is expanded, and the reciprocating rotation makes the wheat flour move more vigorously, so that the wheat flour and water can be evenly stirred for washing. At the same time, under the action of the spring 40, the brush plate 41 is made to fit against the inside of the washing tank 1 to scrape off the wheat flour adhering to its inner wall and prevent it from sticking. After the washing is completed, the liquid outlet pipe 4 is opened to discharge the water.

[0064] Example 2

[0065] During actual use, operators found that when washing wheat flour with this device, the mixing ratio of wheat flour and impurities added to the screening box 22 varies each time. Therefore, when washing wheat flour, a certain amount of water needs to be added to the washing tank 1 according to the net content of the wheat flour. If the mixing ratio of wheat flour to water is lower than the preset value, it indicates that there is too much wheat flour, which will lead to incomplete washing and excessive starch content in the mixture, preventing effective separation of wheat flour from starch. If the mixing ratio of wheat flour to water is higher than the preset value, it indicates that there is too little wheat flour, causing the wheat flour to be diluted in the water and unusable. Therefore, to solve the above technical problems, the device was improved according to the method described in this embodiment.

[0066] A slider 46 is provided on the bottom side of the screening box 22 away from the stirring shaft 5. The slider 46 extends into the screening box 22 and is connected to one end of the screen 27. A limiting component is provided below the screen 27 to limit the screen 27 from falling downward. A pressure sensor is provided on the brush plate 41 to detect the pressure value of the washing tank 1 on the brush plate 41. Telescopic components are provided in both the eccentric block 17 and the first connecting rod 12 to control the extension and retraction of the eccentric block 17 and the first connecting rod 12.

[0067] First, wheat flour containing impurities is fed into the screening box 22. The dual-shaft motor 14 is controlled to synchronously drive the eccentric block 17 and the first connecting rod 12 to rotate. During the rotation of the eccentric block 17, the extrusion plate 18 is continuously extruded, and the spring damper 21 causes the screening box 22 to reciprocate up and down. At the same time, the reciprocating screw 25 is rotated by the rotation of the bevel gear 19. This causes the flipping plate 30 to move left and right and flip up and down in the screening box 22 through the displacement rod 45 and the second gear 29, thereby effectively separating the wheat flour from the impurities. The rotation of the first connecting rod 12 causes the L-shaped block 11 to reciprocate up and down on the limit rod 10. The first rack 6 and the first gear 7 cause the stirring shaft 5 to reciprocate up and down in the washing tank 1 and rotate, thereby fully mixing and stirring the wheat flour falling into the screening box 22 with the water in the washing tank 1, improving the washing effect of the wheat flour.

[0068] Secondly, the pressure sensor installed on the brush plate 41 is used to detect the pressure value of the brush plate 41 in real time. Since the amount of water sprayed from the nozzle 36 remains constant in the initial state, if the pressure value of the brush plate 41 is detected to be greater than the preset range, it indicates that the water content in the solution in the washing tank 1 is too low, resulting in a viscous solution. Wheat flour is adsorbed on the side wall of the washing tank 1 during the stirring process. At this time, the water output of the nozzle 36 is increased and the end of the first connecting rod 12 near the L-shaped block 11 is controlled to extend. During this process, the rotation speed of the stirring shaft 5 is matched with the travel speed of the first gear 7 on the first rack 6, and the travel speed of the first gear 7 is matched with the travel speed of the dual-shaft motor 14. The rotational speed is matched, and when the first connecting rod 12 extends, the travel speed of the first gear 7 will be affected by the rotational speed of the dual-shaft motor 14 and the extension length of the first connecting rod 12, thereby increasing the travel speed of the first gear 7, increasing the rotational speed and vertical movement range of the stirring shaft 5. At this time, due to the increased rotational speed of the stirring shaft 5, the centrifugal force on the brush plate 41 will also increase synchronously, thereby improving the scraping effect of the brush plate 41 on the wheat flour adsorbed on the side wall of the washing tank 1, scraping off the wheat flour adsorbed on the side wall of the washing tank 1 and making it fully washed, effectively avoiding the problem of incomplete washing of wheat flour due to the mixing ratio of wheat flour and water being lower than the preset value.

[0069] It should be noted that by controlling the first connecting rod 12 to extend and increase the water content in the washing tank 1, the brush plate 41 can rotate rapidly in the washing tank 1 while the amount of material fed into the screening box 22 remains unchanged, so that the mixing ratio of wheat flour and water in the washing tank 1 is restored to the preset range.

[0070] Finally, when the pressure value detected on the brush plate 41 is less than the preset range, it indicates that the screen 27 is clogged, causing a large amount of wheat flour to be unable to fall into the washing tank 1 through the screen 27. At this time, by controlling the telescopic component set on the eccentric block 17, the end of the eccentric block 17 away from the center retracts towards the center, thereby causing the screening box 22 to lose the squeezing support of the eccentric block 17. The screening box 22 will move towards the washing tank 1 under the action of gravity. At this time, the bottom of the screening box 22 will move into the interior of the washing tank 1. During this process, by controlling the telescopic component located on the first connecting rod 12, the side near the L-shaped block 11 is extended, increasing the range of motion of the L-shaped block 11 on the limiting rod 10, thereby causing the stirring shaft 5 to drive the brush plate 41 to move upwards significantly. The screen 22 moves downwards and reciprocates. Since the bottom of the screening box 22 is located inside the washing tank 1, when the brush plate 41 moves upwards and rotates inside the washing tank 1, the top of the brush plate 41 will contact the bottom of the screening box 22 and squeeze the slider 46 located at the bottom of the screening box 22, causing the slider 46 to move upwards. This causes the slider 46 to drive one side of the screen 27 to move upwards inside the screening box 22, so that the screen 27 contacts the rotating flip plate 30. The rotating flip plate 30 causes the screen 27 to deform, squeezing out the wheat flour that is blocked on the screen 27. This effectively clears the blockage of the screen 27 and solves the problem of the screen 27 being blocked, which prevents a large amount of wheat flour from falling into the washing tank 1 and affects the washing effect of the wheat flour.

[0071] It should be noted that this invention uses a pressure sensor on the brush plate 41 to monitor the washing of wheat flour in the washing tank 1. If the pressure value is less than a preset value, it indicates that the screen 27 is clogged. By controlling the telescopic components on the eccentric block 17 and the first connecting rod 12, the brush plate 41 and the slider 46 are brought into contact, and the slider 46 is pushed to cause the screen 27 to collide with the flipping plate 30, shaking off the wheat flour clogged on the screen 27. When the pressure value is greater than the preset value, it indicates that the wheat flour content is too high. By controlling the telescopic components on the first connecting rod 12 to extend, the centrifugal force on the brush plate 41 is increased synchronously, thereby improving the scraping effect of the brush plate 41 on the wheat flour adsorbed on the side wall of the washing tank 1. The wheat flour adsorbed on the side wall of the washing tank 1 is scraped off and thoroughly washed, effectively avoiding the problem of incomplete washing of wheat flour due to the mixing ratio of wheat flour and water being lower than the preset value.

[0072] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

9. A method of using a wheat flour starch separation and purification assembly by washing, wherein the method employs the wheat flour starch separation and purification assembly as described in any one of claims 1-8 for washing, characterized in that, The specific steps include: S1. Add wheat flour to the screening box and start the dual-shaft motor. The dual-shaft motor drives the eccentric block to rotate, so that the eccentric block continuously squeezes the extrusion plate, causing the screening box to slide upward and return to its original position under the action of the spring damper. This causes the screening box to vibrate, screening the wheat flour and filtering out impurities in the wheat flour. S2. Simultaneously, the rotating bevel gear and the driven bevel gear work together to make the grooved cylinder and the convex rod rotate at the same time, and the convex rod slides relative to the grooved cylinder, so that the first bevel gear and the second bevel gear rotate continuously, causing the reciprocating screw to rotate, and the displacement rod to move back and forth. When the displacement rod moves, the second gear rotates under the action of the second rack, which makes the turntable rotate, and the flipping plate moves left and right while also oscillating, turning over the wheat flour to avoid the accumulation of wheat flour and affecting the screening efficiency. S3. After the wheat flour enters the washing tank, the water pump is started. The water pump draws water from the tank, which is then routed through a hose to the annular tube and sprayed from the nozzle. Simultaneously, the output of the dual-shaft motor on the right side causes the second and first connecting rods to rotate, making the L-shaped block slide back and forth on the limit rod. This causes the first gear to rotate under the action of the first rack, and the stirring shaft to move up and down and rotate back and forth under the action of the speed bevel gear and the drive bevel gear. This causes the annular tube to rotate back and forth, expanding the spray range of the water flow and making it more uniform. Then, the stirring blades move up and down, expanding the longitudinal stirring range, and the reciprocating rotation makes the wheat flour move more vigorously, thus uniformly stirring the wheat flour and water for washing. At the same time, under the action of the spring, the brush plate fits into the inside of the washing tank, scraping off the wheat flour adhering to the inner wall of the cavity to prevent it from sticking. S4. After rinsing with water, open the outlet pipe to drain the liquid.
