[0002] Corn, commonly known as corncob, maize, corn cob, and corn, originated in the areas along the Andes in Mexico and Peru in Latin America. With the development of the world's shipping industry, corn gradually spread to all parts of the world and became one of the most important food crops. Corn is rich in protein, fat, vitamins, trace elements, fiber, and polysaccharides, etc., and has great potential for developing high-nutrition and high-biological-function foods.

Specific embodiments

[0028] The technical solutions of this patent will be further described in detail below in conjunction with specific embodiments: Embodiment 1

[0029] Please refer to Figure 1-8, A sewage pressure filtration treatment device for the corn processing process, including a working box 1, a guide pipe 3 is fixed on the working box 1, a liquid collecting tank 2 and a slag block collecting box 15 are installed at the bottom of the working box 1. It is characterized in that, on the working box 1, an upper roller II 37 and a lower roller II 38 are rotatably installed. On both the upper roller II 37 and the lower roller II 38, a transmission gear 12 is coaxially fixed. The two transmission gears 12 are meshed and connected. A transverse elastic component is installed on the working box 1. An upper roller I 22 is rotatably installed on the transverse elastic component. A squeezing belt 21 is drivingly connected between the upper roller I 22 and the upper roller II 37. On the working box 1, a lower roller I 20 is rotatably installed below the upper roller I 22. A pressure filter belt 11 is drivingly connected between the lower roller I 20 and the lower roller II 38 above the liquid collecting tank 2. The lower port of the guide pipe 3 corresponds to the pressure filter belt 11. A support plate 44 for supporting the pressure filter belt 11 is fixed on the working box 1. A translation frame 8 is reciprocatingly slidably installed on the working box 1. An elevating frame 18 is vertically slidably installed on the translation frame 8 through a vertical elastic component. A pressure roller 19 in contact with the squeezing belt 21 is rotatably installed at the bottom of the elevating frame 18. A baffle plate 10 is rotatably installed on the guide pipe 3. An elastic support component is connected between the baffle plate 10 and the guide pipe 3. A transverse guide rod 33 is fixed on the working box 1. A sleeve block 29 is slidably sleeved on the transverse guide rod 33. A pushing plate 9 is fixed on the sleeve block 29. The lower end of the pushing plate 9 is in transverse contact with the baffle plate 10. A sleeve 4 corresponding to the pushing plate 9 transversely is fixed on the translation frame 8.

[0030] When this device is in use, during the corn processing process, after preliminary processes such as sedimentation and filtration, the muddy sludge obtained enters the guide pipe 3. After the baffle plate 10 is opened, the sludge enters the pressure filter belt 11. The transmission squeezing belt 21 is driven to move by the upper roller I and the upper roller II 37, and the pressure filter belt 11 is driven to move by the lower roller I 20 and the lower roller II 38, so as to realize the pressure filtration operation on the sludge between the squeezing belt 21 and the pressure filter belt 11.

[0031] Among them, a gear box 5 is fixed on the working box 1. A threaded rod 7 threadedly connected with the sleeve 4 is rotatably installed on the gear box 5. Two transmission bevel gears 39 inside the gear box 5 are coaxially fixed on the threaded rod 7. An idler bevel gear 40 that alternately meshes with the two transmission bevel gears 39 is rotatably installed inside the gear box 5. A double-shaft motor 6 for driving the idler bevel gear 40 is fixed on the gear box 5.

[0032] By setting the double-shaft motor 6, the threaded rod 7 can be driven to rotate. The threaded rod 7 drives the sleeve 4 to drive the translation frame 8 to linearly move horizontally, so as to realize the linear movement of the pressure roller 19 and push and press the squeezing belt 21, promoting the full pressure filtration operation of the sludge.

[0033] Specifically, the biaxial motor 6 can drive the incomplete bevel gear 40 to rotate. The incomplete bevel gear 40 alternately meshes with two transmission bevel gears 39. At this time, the transmission bevel gear 39 drives the threaded rod 7 to rotate clockwise and counterclockwise alternately, so that the translation frame 8 can move back and forth horizontally, realizing the reciprocating movement of the pressing roller 19, and promoting the repeated pressure filtration operation of the sludge.

[0034] Furthermore, the vertical elastic component of the device includes a column 25 vertically penetrating the translation frame 8. A vertical spring 26 is fixedly connected between the column 25 and the lifting frame 18. A horizontally arranged limiting block 16 is fixed on the working box 1. An inclined groove I24 and an inclined groove II45 are formed on the limiting block 16 and are arranged obliquely upward. The inclined groove II45 and the inclined groove I24 are parallel to each other. The inclined groove I24 and the inclined groove II45 penetrate the limiting block 16. A guiding roller 23 in contact with the limiting block 16 is rotatably installed on the lifting frame 18. A guiding inclined plate 46 at the lower end of the inclined groove I24 is fixedly installed at the bottom of the limiting block 16.

[0035] Through the above settings, as Figure 4 shown, during the process of the translation frame 8 moving to the right, the guiding roller 23 moves to the right and the vertical spring 26 vertically pushes down on the lifting frame 18. At this time, the pressing roller 19 vertically presses the extrusion belt 21, so that the extrusion belt 21 presses the sludge downward, thereby realizing the pressure filtration operation of the extrusion belt 21 and the pressure filter belt 11 on the sludge. When the guiding roller 23 abuts against the guiding inclined plate 46, the guiding roller 23 enters the inclined groove I24 and moves upward until the guiding roller 23 moves above the limiting block 16. During this process, the pressing roller 19 does not push against the extrusion belt 21, and there is an interval between the extrusion belt 21 and the pressure filter belt 11, which is convenient for the sludge to enter. When the translation frame 8 moves to the left, the guiding roller 23 moves to the left accordingly. When the guiding roller 23 moves into the inclined groove II45, the guiding roller 23 moves obliquely downward until the guiding roller 23 enters below the limiting block 16, and then the translation frame 8 moves to the right. In this way, by means of the abutting pressure of the guiding roller 23, the pressure filter belt 11 and the extrusion belt 21 perform repeated pressure filtration operations on the sludge.

[0036] The transverse elastic component of the device includes a sliding frame 34 slidably installed horizontally on the working box 1. The upper roller I22 is rotatably installed on the sliding frame 34. A limiting plate 36 is fixed on the working box 1. A transverse spring 35 is fixedly connected between the limiting plate 36 and the sliding frame 34. During the process of the pressing roller 19 pressing down the extrusion belt 21, the transverse spring 35 is elastically compressed. When the pressing roller 19 moves upward, the transverse spring 35 elastically returns to its original state, so that the extrusion belt 21 can always maintain a tight state and have a flat extrusion surface, and at the same time can ensure the stable conveying effect of the extrusion belt 21, greatly improving the pressure filtration effect on the sludge.

[0037] In addition, an incomplete gear 14 is rotatably mounted on the working box 1. The incomplete gear 14 is drivingly connected to the output shaft of the dual-axis motor 6 through a pulley mechanism 13. The incomplete gear 14 intermittently meshes with the transmission gear 12. A ratchet wheel 41 is coaxially fixed on the lower roller II 38. A pawl 42 is rotatably mounted on the working box 1 through a torsion spring 43. The pawl 42 abuts against the ratchet teeth of the ratchet wheel 41.

[0038] The dual-axis motor 6 drives the incomplete gear 14 to rotate through the pulley mechanism 13. The incomplete gear 14 intermittently meshes with one of the transmission gears 12. At this time, the two transmission gears 12 rotate in opposite directions, realizing the reverse rotation of the upper roller II 37 and the lower roller II 38, so that the extrusion belt 21 and the pressure filter belt 11 convey the sludge, and the extrusion belt 21 and the pressure filter belt 11 can convey the sludge step by step, avoiding the accumulation of sludge, and realizing the segmented conveying and pressure filtration operations of the sludge. Embodiment 2

[0039] Please refer to Figure 1-8 , on the basis of Embodiment 1, in addition, the elastic support assembly of the device includes a vertical slider 30 vertically and slidably mounted on the material guide pipe 3. A support rod 28 is hinged between the vertical slider 30 and the baffle plate 10. A bottom plate 32 is fixed on the material guide pipe 3. A support spring 31 is fixedly connected between the bottom plate 32 and the vertical slider 30.

[0040] During the process of the threaded transmission between the threaded rod 7 and the sleeve 4, the sleeve 4 moves horizontally back and forth. When the sleeve 4 moves towards the pushing plate 9 to push it, the pushing plate 9 pushes the baffle plate 10. At this time, the baffle plate 10 rotates clockwise, realizing the opening of the material guide pipe 3. The sludge in the material guide pipe 3 slides along the baffle plate 10 into the space between the extrusion belt 21 and the pressure filter belt 11 for blanking. When the sleeve 4 moves in the direction away from the pushing plate 9, under the support of the support spring 31, the support rod 28 pushes the baffle plate 10 to reset, and at this time, the blanking stops. By repeating the above actions, the intermittent blanking effect of the sludge is realized, effectively avoiding the accumulation of sludge and ensuring the full pressure filtration of the sludge subsequently.

[0041] In addition, the baffle plate 10 is inclined. A plurality of equally spaced partition plates 27 are fixedly installed on the baffle plate 10. The upper ends of the partition plates 27 abut against the bottom of the pushing plate 9. The arranged partition plates 27 can separate the sludge to be dropped, realizing the uniform blanking effect of the sludge, so that the extrusion belt 21 and the pressure filter belt 11 can filter the sludge more evenly.

[0042] In addition, two scraping plates 17 are fixed to the end of the working box 1 above the slag block collecting box 15. The two scraping plates 17 are respectively in contact with the right ends of the pressure filter belt 11 and the extrusion belt 21. The sludge after pressure filtration forms slag blocks and falls into the slag block collecting box 15. The scraping plates 17 can scrape and clean the surface slag blocks of the extrusion belt 21 and the pressure filter belt 11, effectively promoting the falling and collection of the slag blocks.

[0043] In summary, through the horizontal reciprocating movement of the translation frame 8, the pressing roller 19 presses the extrusion belt 21 downward under the pushing action of the vertical elastic component, so that the extrusion belt 21 and the pressure filter belt 11 can perform pressure filtration on the sludge between them. During the horizontal reciprocating movement of the pressing roller 19, repeated pressure filtration of the sludge is realized. Under the limiting action of the limiting block 16, when the pressing roller 19 slides to the right, it slides while pushing the extrusion belt 21. When the pressing roller 19 slides to the left, the pressing roller 19 moves upward and does not push the extrusion belt 21, which is convenient for the sludge to enter between the extrusion belt 21 and the pressure filter belt 11, achieving the effect of gradually and repeatedly pressure filtering the sludge and greatly improving the degree of full pressure filtration of the sludge. By setting the horizontal movement of the sleeve 4 to push the pushing plate 9, the pushing plate 9 slides by pushing against the baffle plate 10, which can not only intermittently convey the sludge by deflecting the baffle plate 10, but also the partition plate 27 on the baffle plate 10 can shunt the falling sludge, enabling the sludge to achieve the effect of uniform cloth placement, avoiding the accumulation of sludge, and effectively improving the degree of full pressure filtration of the sludge.
