DETAILED DESCRIPTION

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Example:

[0027] like Figures 1 to 5 As shown, this embodiment provides a slurry filtering device for soybean grinding, including a box body 1, a mounting seat 2 is provided in the box body 1, a mounting frame A3 with a higher left side and a lower right side is installed on the mounting seat 2, a filter cloth A4 is provided on the middle opening of the mounting frame, the filter cloth A4 is flush with the upper surface of the mounting frame A3, a through hole 5 communicating with each other from top to bottom is provided on the mounting seat 2, the through hole 5 is below the filter cloth A4, a liquid outlet component A6 is provided on the top left side of the box body 1, the liquid outlet of the liquid outlet component A6 points to the filter cloth A4 and the spraying direction is perpendicular to the upper surface of the filter cloth A4, a liquid outlet component B7 is provided on the top left end of the mounting seat 2, the liquid outlet of the liquid outlet component B7 points to the filter cloth A4 and the spraying direction is perpendicular to the upper surface of the filter cloth A4 The surface of the box body 1 is flush, and a liquid extraction component A8 is provided on the top of the box body 1 for alternately extracting liquid from a distant slurry source to the liquid outlet component A6 and the liquid outlet component B7. A waste outlet 9 is provided on the right side of the box body 1 and is aligned with the right end of the mounting frame A3. The box body 1 is provided with a return port 11 below the waste outlet 9. A waste storage box 10 covering the waste outlet 9 and the return port 11 is provided on the right side outside the box body 1. A mounting frame B12 of a similar shape is installed on the return port 11. A filter cloth B13 is provided at the middle opening of the mounting frame B12. The bottom of the waste storage box 10 is shaped like an inclined surface inclined downward toward the return port 11. A liquid extraction component B14 is provided on the left side outside the box body 1. The liquid inlet of the liquid extraction component B14 leads to the top of the bottom of the box body 1, and an observation window 15 is provided on the front side of the box body 1.

[0028] By using the liquid pumping assembly A8, the liquid outlet assembly A6 and the liquid outlet assembly B7 in combination, slurry flows with different spraying directions are alternately produced, so that the upper surface of the filter cloth A4 that plays the role of filtering slurry is cleaned when the device is running, so that the device can perform the slurry filtering operation for a long time, and the slurry filtering efficiency is improved; the slurry is sprayed onto the filter cloth A4 through the liquid outlet assembly A6 and the liquid outlet assembly B7 respectively under the drive of the liquid pumping assembly A8, and the slurry sprayed from the liquid outlet assembly A6 has a spraying direction perpendicular to the filter cloth A4, so the slurry is buffered and decelerated by the filter cloth A4 and then slowly flows along the upper surface of the filter cloth A4. The slurry flows slowly. During the flow, the slurry passes through the filter cloth A4 and flows to the bottom of the box body 1. The slurry sprayed from the liquid outlet component B7 has a spraying direction that is flush with the upper surface of the filter cloth A4. Therefore, the slurry can wash the upper surface of the filter cloth A4 at a relatively high speed, and wash the impurities accumulated on the upper surface of the filter cloth A4 to the waste outlet 9 at the right end and send them to the waste storage box 10. The slurry flowing into the waste storage box 10 can flow back to the bottom of the box body 1 through the reflux port 11. The filter cloth B13 blocks the impurities in the waste storage box 10. The slurry accumulated at the bottom of the box body 1 is finally pumped out of the box body 1 by the liquid pumping component B14.

[0029] Furthermore, the liquid extraction component A8 includes a liquid extraction pump A16, an infusion tube A17, an infusion tube B18, a liquid discharge tube A19, a liquid discharge tube B20 and a three-way valve 21. The liquid extraction pump A16 and the three-way valve 21 are provided on the top of the box body 1. The inlet of the liquid extraction pump A16 is connected to the infusion tube A17 leading to a distant slurry source, and the outlet of the liquid extraction pump A16 is connected to the infusion tube B18 leading to the three-way valve 21. Among the two valve ports of the three-way valve 21 that are not connected to the infusion tube B18, one is connected to the liquid discharge tube A19 leading to the liquid outlet component A6, and the other is connected to the liquid discharge tube B20 leading to the liquid outlet component B7.

[0030] The three-way valve 21 is manipulated to alternately change the connection state between the pump A16 and the liquid outlet assembly A6 and between the pump A16 and the liquid outlet assembly A6, so as to achieve the effect of alternately spraying slurry from the liquid outlet assembly A6 and the liquid outlet assembly B7. The pump A16 delivers the slurry to the three-way valve 21 through the infusion pipe A17 and the infusion pipe B18. When the pump A16 is connected to the liquid outlet assembly A6, the slurry passing through the three-way valve 21 flows to the liquid outlet assembly A6 through the liquid delivery pipe A19. When the pump A16 is connected to the liquid outlet assembly B7, the slurry passing through the three-way valve 21 flows to the liquid outlet assembly B7 through the liquid delivery pipe B20.

[0031] Furthermore, the liquid outlet component A6 includes a liquid separating box A22 and a liquid outlet head A23. The liquid separating box A22 is provided on the left side of the top of the box body 1. There is a cavity inside the liquid separating box A22. The top of the liquid separating box A22 is connected to a liquid discharge pipe A19 connected to the internal cavity thereof. The bottom of the liquid separating box A22 is evenly provided with liquid outlet heads A23 facing the filter cloth A4, and the liquid outlet head A23 is connected to the cavity inside the liquid separating box A22.

[0032] The slurry flows into the cavity inside the liquid separation box A22 along the liquid flow pipe A19, and then is evenly sprayed onto the left side of the filter cloth A4 from each liquid outlet head A23, and slowly flows to the right along the filter cloth A4 after being buffered and decelerated. During this flow process, the slurry gradually passes through the filter cloth A4, and impurities are left on the upper surface of the filter cloth A.

[0033] Furthermore, the liquid outlet component B7 includes a liquid separator box B24 and a liquid outlet head B25. The liquid separator box B24 is provided at the left end of the top of the mounting seat 2. The liquid separator box B24 has a cavity inside. The top of the liquid separator box B24 is connected to a liquid discharge pipe B20 connected to the internal cavity. The liquid outlet heads B25 are evenly arranged from front to back on one side of the liquid separator box B24 facing the filter cloth A4. The liquid outlet heads B25 are connected to the cavity inside the liquid separator box B24.

[0034] The slurry flows into the cavity inside the liquid separation box B24 along the liquid flow pipe B20, and then is evenly sprayed onto the filter cloth A4 from each liquid outlet head B25. When the slurry flows rapidly to the right along the upper surface of the filter cloth A4, it can carry the impurities on the filter cloth A4 together, and finally flush the impurities into the waste storage box 10 through the waste discharge port 9. The slurry that flows into the waste storage box 10 flows into the bottom of the box body through the filter cloth B13.

[0035] Furthermore, a mounting groove 26 corresponding to the shape of the outer edge of the mounting frame A3 is provided on the top of the mounting seat 2 outside the through opening 5, and the mounting frame A3 is placed in the mounting groove 26. A maintenance port 27 is provided on the right side of the box body 1, and a double door 28 is hinged on the maintenance port 27. The closing part of the double door 28 is provided with corresponding locks 29, and the two door panels of the double door 28 are respectively provided with a handle 30.

[0036] During subsequent cleaning, the staff can easily replace the installation frame A3 placed in the installation slot 26 through the maintenance opening 27. When the maintenance opening 27 needs to be opened, the staff can unlock the lock 29 and hold the handle 30 to open the double door 28.

[0037] Furthermore, a waste taking-out opening 31 is provided at the top of the waste storage box 10 , a sealing door 32 is hinged on the waste taking-out opening 31 , and a handle groove 33 is provided on the sealing door 32 .

[0038] During subsequent cleaning, the staff can conveniently clean the impurities accumulated in the waste storage box 10 and clean the filter cloth B13 on the filter frame B located on the reflux port 11 through the waste outlet 31 .

[0039] Furthermore, the mounting frame B12 can be assembled and disassembled from the reflux port 11 . A buckle 37 is provided on the mounting frame B12 . A slot 38 corresponding to the buckle 37 is provided on the upper side of the reflux port 11 of the box body 1 . The buckle 37 is inserted into the slot 38 .

[0040] The staff can install and remove the installation frame B12 on the return port 11 through the waste port 31. After the installation frame B12 is removed, it is more convenient to clean the filter cloth B13. When the installation frame B12 is installed on the return port 11, the buckle 37 and the slot 38 are used together to help the installation frame B12 stay stably on the return port 11. Specifically, a blocking block is provided at the return port 11 inside the box body 1, and the blocking block blocks the installation frame B12 to prevent the installation frame B12 from mistakenly entering the box body 1 from the return port 11.

[0041] Furthermore, the liquid extraction component B14 includes a liquid extraction pump B34, a drainage pipe A35 and a drainage pipe B36. The liquid extraction pump B34 is provided on the left side outside the box body 1. The inlet of the liquid extraction pump B34 is connected to the drainage pipe A35 leading to the upper bottom of the box body 1, and the outlet of the liquid extraction pump B34 is connected to the drainage pipe B36 leading to the subsequent treatment of the slurry.

[0042] The liquid pump B34 extracts the slurry stored at the bottom of the box body 1 through the liquid discharge pipe A35, and then sends the extracted slurry to the subsequent treatment through the liquid discharge pipe B36.

[0043] Furthermore, the bottom of the box body 1 is shaped as a slope with a lower left side and a higher right side, and the port of the drainage pipe A35 on the inner side of the box body 1 is located above the left side of the bottom of the box body 1. The bottom of the box body 1 is shaped as a slope that slopes downward from the right side to the left side, so that the slurry can flow to the position of the liquid outlet pipe A on the left side as much as possible, so that the slurry can be more conveniently pumped from the drainage pipe A35 to the liquid pump B34, reducing the amount of slurry remaining in the box body 1.

[0044] Furthermore, the outer edges of the front and rear sides of the installation frame are provided with side plates 39 that are inclined downward toward the middle, and the side plates 39 are provided with sealing strips 40 facing outward, and the sealing strips 40 are closely attached to the inner walls of the front and rear sides of the box body 1. The sealing strips 40 are used to improve the sealing performance, reduce the probability of the slurry passing through the gap between the installation frame A3 and the inner wall of the box body 1, and the slurry splashed to the front and rear sides flows back along the side plates 39 to the filter cloth A4 in the middle of the installation frame A3, thereby improving the filtering effect.

[0045] The working principle and use process of this utility model:

[0046] When filtering, the staff starts the liquid pump A16 and the liquid pump B34, and operates the three-way valve regularly to control whether the liquid pump A16 is connected to the liquid outlet component A6 or the liquid outlet component B7. Since the filter cloth A4 is the main filtering component, the time for the liquid outlet component A6 to spray the slurry once should be much longer than the time for the liquid outlet component B7 to spray the slurry once, so that more slurry can flow to the bottom of the box body 1 after being filtered by the filter cloth A4. Because there will be more impurities in the waste storage box 10 before cleaning, the slurry passing speed of the filter cloth B13 is slow, so only enough slurry is guaranteed to wash away the impurities on the filter cloth A4, so as to limit the slurry flowing into the waste storage box and reduce the impact on the filtering efficiency. When cleaning afterwards, the staff replaces the installation frame A3 from the maintenance port 27, cleans the waste storage box 10 from the waste removal port 31, and replaces the installation frame B12.

[0047] The above are only specific application examples of the utility model, and do not constitute any limitation on the protection scope of the utility model. Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the utility model.
