Description
Technical Field
[0001] This utility model belongs to the field of flour processing technology, specifically relating to a raw material cleaning device for wheat flour production. Background Technology
[0002] Wheat is used as a raw material for wheat flour production. During wheat flour production, it is necessary to remove the floating wheat mixed in with the wheat. Floating wheat, also known as husk wheat or white wheat, is the husk that floats on top of the wheat when it is washed. It is caused by the loose, cracked or moldy husks around the wheat, which causes the wheat to lose its weight and float when the wheat is washed. In the current technology, people need to hold a net basket to continuously drain the floating wheat from the top, which is complicated and not conducive to long-term operation. Utility Model Content
[0003] The purpose of this invention is to provide a raw material cleaning device for wheat flour production, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A raw material cleaning device for wheat flour production includes a cleaning tank. A primary filter screen is connected to the lower part of the inner cavity of the cleaning tank. A partition mechanism is provided above the primary filter screen. The partition mechanism includes a secondary filter screen, a strip-shaped groove, a primary contact switch, and a strip-shaped plate. The strip-shaped groove is located on the right side of the cleaning tank. The secondary filter screen passes through the strip-shaped groove and is positioned above the primary filter screen. The primary contact switch is embedded in the left wall of the inner cavity of the cleaning tank. The strip-shaped plate is connected to the left side of the bottom end of the secondary filter screen and is flush with the primary contact switch. The right side of the secondary filter screen is connected to... The device has a telescopic mechanism, which includes a longitudinal plate, an assembly plate, and a drive motor. The longitudinal plate is located on the right side of the cleaning tank and is connected to the secondary filter. The assembly plate is fixedly connected to the rear left side of the cleaning tank by positioning bolts. The drive motor is fixedly connected to the left side of the assembly plate by positioning bolts. Drain pipes are equidistantly connected to the bottom right side of the cleaning tank, and a primary solenoid valve is installed on the drain pipe. A feed hopper is connected to the middle of the top of the cleaning tank. Water inlet pipes are symmetrically connected to the left and right sides of the top of the cleaning tank, and a secondary solenoid valve is installed on the water inlet pipe.
[0006] Preferably, the partition mechanism further includes an inclined panel and a connecting slot. The inclined panel is symmetrically arranged on both sides of the inner cavity of the washing tank and is located at the top of the secondary filter. The connecting slot is opened on the left side wall of the inner cavity of the washing tank and its left end penetrates through the washing tank. The connecting slot is located below the primary contact switch. A tertiary filter is provided in the connecting slot. The inclined panel restricts the secondary filter, improving its stability. The tertiary filter makes it difficult for wheat and floating wheat to enter the connecting slot.
[0007] Preferably, the partition mechanism further includes a square tube, an opening, and an exhaust pipe. The square tube is connected to the left side of the cleaning tank, the opening is located on the lower right side of the square tube and is connected to the connecting slot, and the exhaust pipe is connected to the middle of the top of the square tube. Water enters the square tube through the opening, and the exhaust pipe ensures that the float can rise and fall within the cavity of the square tube.
[0008] Preferably, the partition mechanism further includes an overhead plate, a float, and a secondary contact switch. The overhead plate is symmetrically connected to the lower part of the inner cavity of the square tube and is located above the opening. The float is located at the top of the overhead plate, and the secondary contact switch is embedded at the top of the left side wall of the inner cavity of the square tube. The water liquid drives the float to rise, and when the float rises to the top of the inner cavity of the square tube, the float contacts the secondary contact switch.
[0009] Preferably, the telescopic mechanism further includes a sleeve, a screw, a transition plate, a stabilizing frame, and a transverse strip. The transition plate is connected to the rear side of the longitudinal plate, and the sleeve bearing is connected to the left side of the transition plate. The left end of the screw is connected to the output end of the drive motor, and the right end of the screw passes through the assembly plate and is located inside the sleeve. The screw is threadedly connected to the sleeve via an external thread. The stabilizing frame is symmetrically connected to the outer wall of the sleeve, and the front side of the stabilizing frame slides against the rear side wall of the cleaning tank. The transverse strip slides within a slot on the side of the stabilizing frame opposite to the cleaning tank and is connected to the cleaning tank. The drive motor drives the screw to rotate. Due to the threaded connection between the outer wall of the screw and the inner wall of the sleeve, the rotation of the screw causes the sleeve to move to the left, thereby causing the transition plate, the longitudinal plate, and the secondary filter to move to the left. The stability of the sleeve is enhanced by the stabilizing frame and the transverse strip.
[0010] Preferably, a stepper motor is provided in the middle of the bottom of the cleaning tank. The output end of the stepper motor is connected to a rotating shaft. The top of the rotating shaft passes through the bottom of the cleaning tank and the primary filter. A scraper is connected to the outer wall of the rotating shaft in a circumferential array. The scraper is located at the top of the primary filter. When the stepper motor is turned on, the wheat on the top of the primary filter is agitated through the rotating shaft and the scraper, causing the wheat to flow between the primary and secondary filters, thereby enhancing the effect of separating dust from the surface of the wheat and improving the cleaning quality.
[0011] Preferably, the front side of the washing box is provided with a collection slot, and there are two sets of collection slots. The bottom surface of the upper collection slot is flush with the top surface of the secondary filter screen, and the bottom surface of the lower collection slot is flush with the top surface of the primary filter screen. The collection slot is equipped with a box door. By opening the box door, the wheat on the top of the primary filter screen and the floating wheat on the top of the secondary filter screen can be collected.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, this utility model monitors the water volume through a separation mechanism and separates the floating wheat on the upper layer of the water from the sinking wheat through a secondary filter screen, thereby ensuring the separation of wheat from the floating wheat during wheat washing and ensuring the washing effect. Furthermore, the wheat on the top of the primary filter screen is agitated by a stepper motor, a rotating shaft, and a scraper, causing the wheat to flow between the primary and secondary filter screens, thereby enhancing the effect of separating dust from the wheat surface and improving the washing quality.

[0022] Example 1
[0023] Please see Figures 1-8 As shown, a raw material cleaning device for wheat flour production includes a cleaning tank 1. A primary filter 2 is connected to the lower part of the inner cavity of the cleaning tank 1. A partition mechanism is provided above the primary filter 2. The partition mechanism includes a secondary filter 3, a strip-shaped groove 4, a primary contact switch 5, and a strip plate 6.

The primary contact switch 5 is embedded in the left wall of the inner cavity of the cleaning tank 1. The strip plate 6 is connected to the left side of the bottom end of the secondary filter 3, and the strip plate 6 is flush with the primary contact switch 5. An extension is connected to the right side of the secondary filter 3. The telescopic mechanism includes a longitudinal plate 7, an assembly plate 8, and a drive motor 9. The longitudinal plate 7 is located on the right side of the cleaning tank 1 and is connected to the secondary filter 3. The assembly plate 8 is fixedly connected to the rear left side of the cleaning tank 1 by positioning bolts. The drive motor 9 is fixedly connected to the left side of the assembly plate 8 by positioning bolts. Drain pipes 10 are equidistantly connected to the bottom right side of the cleaning tank 1. A primary solenoid valve 11 is installed on the drain pipe 10. A feed hopper 12 is connected to the middle of the top of the cleaning tank 1. Water inlet pipes 13 are symmetrically connected to the left and right sides of the top of the cleaning tank 1. A secondary solenoid valve 14 is installed on the water inlet pipe 13.
[0024] refer to Figure 3 , Figure 5 and Figure 6 As shown, the partition mechanism also includes an inclined panel 15 and a connecting slot 16. The inclined panel 15 is symmetrically arranged on both sides of the inner cavity of the washing tank 1, and the inclined panel 15 is located at the top of the secondary filter 3. The connecting slot 16 is opened on the left side wall of the inner cavity of the washing tank 1, and the left end of the connecting slot 16 penetrates the washing tank 1. The connecting slot 16 is located below the primary contact switch 5. A tertiary filter 17 is provided in the connecting slot 16. The inclined panel 15 restricts the secondary filter 3, improving the stability of the secondary filter. The setting of the tertiary filter 17 makes it difficult for wheat and floating wheat to enter the connecting slot 16.
[0025] refer to Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, the partition mechanism also includes a square tube 18, an opening 19, and an exhaust pipe 20. The square tube 18 is connected to the left side of the cleaning tank 1, the opening 19 is opened on the lower right side of the square tube 18, and the opening 19 is connected to the connecting slot 16. The exhaust pipe 20 is connected to the middle of the top of the square tube 18. Water enters the square tube 18 through the opening 19. The exhaust pipe 20 ensures that the float 22 can rise and fall inside the square tube 18.
[0026] refer to Figure 5 and Figure 8 As shown, the partition mechanism also includes an overhead plate 21, a float 22, and a secondary contact switch 23. The overhead plate 21 is symmetrically connected to the lower part of the inner cavity of the square tube 18, and the overhead plate 21 is located above the opening 19. The float 22 is located on the top of the overhead plate 21. The secondary contact switch 23 is embedded in the top of the left side wall of the inner cavity of the square tube 18. The water liquid drives the float 22 to rise. When the float 22 rises to the top of the inner cavity of the square tube 18, the float 22 contacts the secondary contact switch 23.
[0027] refer to Figures 3-7 As shown, the telescopic mechanism also includes a sleeve 24, a screw 25, a transition plate 26, a stabilizing frame 27, and a transverse strip 28. The transition plate 26 is connected to the rear side of the longitudinal plate 7. The sleeve 24 is bearing-connected to the left side of the transition plate 26. The left end of the screw 25 is connected to the output end of the drive motor 9. The right end of the screw 25 passes through the mounting plate 8 and is located inside the sleeve 24. The screw 25 is threaded to the sleeve 24 via an external thread. The stabilizing frame 27 is symmetrically connected to the outer wall of the sleeve 24, and the front of the stabilizing frame 27... The side is slidably engaged with the rear side wall of the cleaning tank 1, and the transverse strip 28 is slidably engaged in the groove of the stabilizing frame 27 on one side of the cleaning tank 1. The transverse strip 28 is connected to the cleaning tank 1. The drive motor 9 drives the screw 25 to rotate. Since the outer wall of the screw 25 is threadedly connected to the inner wall of the sleeve 24, the rotation of the screw 25 causes the sleeve 24 to move to the left, thereby causing the transition plate 26, the longitudinal plate 7 and the secondary filter 3 to move to the left. The stability of the sleeve is enhanced by the stabilizing frame 27 and the transverse strip 28.
[0028] refer to Figure 3 and Figure 5 As shown, a stepper motor 29 is located in the middle of the bottom of the cleaning tank 1. The output end of the stepper motor 29 is connected to a rotating shaft 30. The top of the rotating shaft 30 passes through the bottom of the cleaning tank 1 and the primary filter 2. A scraper 31 is connected to the outer wall of the rotating shaft 30 in a circumferential array. The scraper 31 is located at the top of the primary filter 2. When the stepper motor 29 is turned on, the wheat on the top of the primary filter 2 is agitated through the rotating shaft 30 and the scraper 31, causing the wheat to flow between the primary filter 2 and the secondary filter 3, thereby enhancing the effect of separating dust from the surface of the wheat and improving the cleaning quality.
[0029] refer to Figure 1 and Figure 2 As shown, the front side of the washing box 1 is provided with a collection slot 32, and there are two sets of collection slots 32. The bottom surface of the upper collection slot 32 is flush with the top surface of the secondary filter screen 3, and the bottom surface of the lower collection slot 32 is flush with the top surface of the primary filter screen 2. The collection slot 32 is equipped with a box door 33. By opening the box door 33, the wheat on the top of the primary filter screen 2 and the floating wheat on the top of the secondary filter screen 3 can be collected.
[0030] Working principle: Wheat is poured into the washing tank 1 through the feed hopper 12. The wheat falls to the top of the primary filter screen 2. Water is then introduced into the washing tank 1 through the water inlet pipe 13 to rinse the wheat. As the amount of water increases, the water level gradually rises. The inner cavity of the square tube 18 is connected to the inner cavity of the washing tank 1 through the connecting slot 16 and the opening 19. The water causes the float 22 to rise. When the float 22 reaches the top of the inner cavity of the square tube 18, it contacts the secondary contact switch 23. The secondary contact switch 23 sends a signal to the peripheral terminal. The peripheral terminal receives the signal and controls the drive motor 9 to start. The drive motor 9 drives the screw 25 to rotate. Since the outer wall of the screw 25 is threadedly connected to the inner wall of the sleeve 24, the rotation of the screw 25 causes the sleeve 24 to move to the left. This causes the transition plate 26, the longitudinal plate 7, and the secondary filter 3 to move to the left. When the strip plate 6 contacts the primary contact switch 5, the primary contact switch 5 sends a signal to the peripheral terminal. The peripheral terminal receives the signal and controls the secondary solenoid valve 14 to close, stopping the water intake. The stepper motor 29 turns on and stirs the wheat on top of the primary filter 2 through the rotating shaft 30 and the scraper 31, causing the wheat to flow between the primary filter 2 and the secondary filter 3, thereby enhancing the effect of separating dust from the surface of the wheat and improving the cleaning quality. After cleaning, the primary solenoid valve 11 is opened, allowing the water to flow to the bottom of the primary filter 2 and carry the dust out through the drain pipe 10. The box door 33 is opened to collect the wheat on top of the primary filter 2 and the floating wheat on top of the secondary filter 3.
