Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a high-efficiency filtering solid-liquid separation agricultural machinery and equipment. Background Art

[0002] Chinese patent document CN210786444U, publication (announcement) date: 2020.06.19, is an agricultural solid-liquid separator disclosed by our company, including an auger and a filter screen. The auger is installed on the frame by rotating the shaft, the filter screen is mounted on the outside of the auger, and the filter screen is fixed to the frame. The rotating shaft of the auger is connected to the output shaft of the motor for transmission. When the auger rotates, the material is squeezed to achieve solid-liquid separation.

[0003] However, during use, there are the following deficiencies: First, during operation, solid-liquid separation is achieved only through extrusion filtration through the auger 20 and the filter screen 13 located outside the auger. The material close to the filter screen has a better filtration effect, but the material close to the central axis of the auger is far away from the filter screen, resulting in a poor solid-liquid separation effect; second, during use, some plant fibers are often attached and entangled inside the filter screen, causing the filter screen to be blocked, thereby further affecting the solid-liquid separation effect of the material.

[0004] In order to solve the above problems, the technical personnel of our company proposed the present application of a high-efficiency filtration solid-liquid separation agricultural machinery equipment. Summary of the invention

[0005] The main purpose of the present invention is to provide a high-efficiency filtering solid-liquid separation agricultural machinery equipment to solve at least one of the above-mentioned technical problems.

[0007] A collecting box is installed at one end of the discharge port of the central shaft, and the discharge port extends into the collecting box. The central shaft and the collecting box are rotatably connected through a bearing. A manifold is connected to the bottom of the collecting box, and the manifold is connected and fixed to the discharge pipe of the solid-liquid separator.

[0008] A scraping device is installed inside the central shaft, and the scraping device includes a fixed rod and a scraper. At least one scraper is axially arranged on the outer wall of the fixed rod. A limiting hole is arranged at one end of the connecting shaft located inside the central shaft. One end of the fixed rod is movably extended into the limiting hole, and the other end is fixedly connected to the collecting box. The scraper contacts the inner wall of the central shaft.

[0009] A cutting portion is arranged on the outer edge of the spiral blade and on one side close to the liquid discharge port of the central axis.

[0010] The cutting portion is provided with a notch.

[0011] The spiral blade is provided with a radial deformation seam.

[0012] The outside of the auger is also provided with a slag cleaning device, which is used to clean the filter screen outside the auger.

[0013] The slag cleaning device comprises a cleaning pipe, which is installed on the outside of the filter screen. The cleaning pipe is provided with a nozzle, which faces the filter screen.

[0014] The slag cleaning device also includes a supporting ring, a rotating ring, a grooved fixed ring and a rotating grooved ring. The supporting ring and the grooved fixed ring are respectively fixedly mounted on both sides of the filter box of the solid-liquid separator. The first ring groove on the grooved fixed ring faces one side of the supporting ring. The rotating ring is rotatably mounted on the supporting ring. The second ring groove of the rotating grooved ring faces the grooved fixed ring. The rotating grooved ring is rotatably buckled on the grooved fixed ring through the second ring groove.

The grooved fixed ring is provided with an input hole connected to the first ring groove. The rotating ring, the rotating grooved ring and the cleaning pipe are rotated by a rotating structure. In use, the input hole is connected to pressurized water or compressed air through a pipeline.

[0015] The rotating structure comprises a driver and ring teeth arranged on the outer circumference of a rotating grooved ring. The driver is installed outside the filter box. The input shaft of the driver extends into the filter box and is equipped with gears. The gears mesh with the ring teeth for transmission.

[0016] The present invention has the following beneficial effects: 1. When the motor of the solid-liquid separator of the present invention drives the auger to rotate, the material between the auger and the filter screen is squeezed, the liquid in the material close to the filter screen is filtered and discharged through the filter screen, and the liquid in the material far from the filter screen enters the central axis through the filter holes on the central axis and is finally discharged from the drain port, thereby improving the effect of solid-liquid separation.

When in use, the input hole is connected to pressurized water or compressed air through a pipeline, so that backwashing can be performed when the filter screen needs to be cleaned. Since the filter screen is fixed, and the cleaning pipe in this embodiment is rotating, the filter screen can be backwashed more completely and comprehensively, further improving the solid-liquid separation effect of the material.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1: See also Figure 1 , 2 4. The present invention provides a high-efficiency filtration solid-liquid separation agricultural machinery equipment, including an auger 20, wherein the auger 20 includes a central shaft 21 and a spiral blade 22 fixedly connected to the central shaft 21, wherein the central shaft 21 is a tubular structure, and a plurality of filter holes 211 are arranged on the central shaft 21, and a connecting shaft 23 is fixedly connected to one end of the central shaft 21, and the connecting shaft 23 closes one end of the central shaft 21, and the other end of the central shaft 21 is opened to form a liquid discharge port, and a motor for driving the auger 20 to rotate is transmission-connected to the connecting shaft 23.

[0034] Through the above structure, when the motor of the solid-liquid separator 10 drives the auger 20 to rotate, the material between the auger 20 and the filter screen 13 is squeezed, the liquid in the material close to the filter screen is filtered and discharged through the filter screen 13, and the liquid in the material far from the filter screen enters the central axis 21 through the filter hole 211 on the central axis 21, and is finally discharged from the drain port, thereby improving the solid-liquid separation effect.

[0035] Further, in order to facilitate the collection of the liquid discharged from the drain port, see Figure 1 A collecting box 30 is installed at one end of the discharge port of the central shaft 21, and the discharge port extends into the collecting box 30. The central shaft 21 and the collecting box 30 are rotatably connected through the bearing 31. A manifold 32 is connected to the bottom of the collecting box 30, and the manifold 32 is connected and fixed to the discharge pipe 12 of the solid-liquid separator. The collecting box 30 can also be fixedly supported by the manifold 32. Of course, in order to facilitate later inspection and maintenance, a docking flange can be provided on the manifold 32 for docking. When the collecting box 30 needs to be disassembled, the docking flange of the manifold 32 is first disassembled to disconnect the manifold 32.

[0036] Embodiment 2: Based on Example 1, see Figure 1 A scraper device 40 is installed inside the central shaft 21. The scraper device 40 facilitates cleaning of the inner wall of the central shaft 21 to prevent sediment from clogging the filter hole 211.

[0037] Specifically, in this embodiment, see Figure 1 , 3 The scraper device 40 includes a fixed rod 41 and a scraper 42. At least one scraper 42 is axially arranged on the outer wall of the fixed rod 41. A limiting hole 231 is arranged at one end of the connecting shaft 23 located inside the central shaft 21. One end of the fixed rod 41 movably extends into the limiting hole 231, and the other end is fixedly connected to the collecting box 30. The scraper 42 contacts the inner wall of the central shaft 21.

[0038] When in use, the auger 20 rotates, and the collecting box 30 is fixedly connected to the drain pipe 12 because the manifold 32 is fixedly connected to the collecting box 30, and the fixed rod 41 is fixedly connected to the collecting box 30 for support. Therefore, when the auger 20 rotates, the scraper device 40 does not rotate, so that the inside of the central shaft 21 is cleaned by the scraper 42, and the fallen sediment is carried out of the drain port with the liquid flow.

[0039] In this embodiment, a flange is provided at one end of the fixing rod 41 connected to the collection box 30 , and the end is a screw structure. The screw structure passes through the collection box 30 and a nut is installed to connect and fix the fixing rod 41 to the collection box 30 .

[0040] Embodiment 3: Based on Example 1 or Example 2, see Figure 4 , 5 , the outer edge of the spiral blade 22, and a cutting portion 221 is provided on the side close to the discharge port of the central shaft 21. The cutting portion 221 is similar to the shape of a knife edge. When the auger 20 rotates, the plant fibers entangled in the filter screen 13 are cut off by the cutting portion 221, so that the plant fibers are easy to separate from the filter screen 13, so as to pass through the filter screen 13, thereby improving the effect of solid-liquid separation.

[0041] Further, see Figure 6 The cutting portion 221 is provided with a notch 222 , so that the cutting portion 221 forms a sawtooth shape, which is convenient for more effectively cutting off the plant fibers entangled inside the filter screen 13 .

[0042] Further, see Figure 4 The spiral blade 22 is provided with a radial deformation seam 223. By providing the deformation seam 223, the spiral blade 22 can be slightly deformed toward the feeding side when extruding the material, so that the cutting part 221 is deformed toward the feeding side, and the distance between the cutting part 221 and the inside of the filter screen 13 is reduced, so that the plant fibers inside the filter screen 13 are cut more cleanly.

[0043] Embodiment 4: Based on Example 1, 2 or 3, see Figure 1 A slag cleaning device 50 is also provided outside the auger 20, and the slag cleaning device 50 is used to clean the filter screen 13 outside the auger 20.

[0044] In one solution, the slag cleaning device 50 includes a cleaning pipe 55, which is installed outside the filter screen 13. The cleaning pipe 55 is provided with a nozzle 551, and the nozzle 551 faces the filter screen 13. In this solution, a plurality of cleaning pipes 55 can be provided, surrounding the filter screen 13, and by connecting pressurized water or compressed air to each cleaning pipe 55, backwashing can be performed when the filter screen 13 needs to be cleaned.

[0045] Embodiment 5: The difference between this embodiment and embodiment 4 is that, see Figure 1 , 78. The slag cleaning device 50 also includes a support ring 51, a rotating ring 52, a grooved fixed ring 53 and a rotating grooved ring 54. The support ring 51 and the grooved fixed ring 53 are respectively fixedly installed on both sides of the filter box 11 of the solid-liquid separator. The first ring groove 531 on the grooved fixed ring 53 faces one side of the support ring 51. The rotating ring 52 is rotatably installed on the support ring 51. The second ring groove 541 of the rotating grooved ring 54 faces the grooved fixed ring 53. The rotating grooved ring 54 is rotatably buckled through the second ring groove 541. On the grooved fixed ring 53, the cleaning pipe 55 is fixedly connected and supported between the rotating ring 52 and the rotating grooved ring 54, and the cleaning pipe 55 is connected to the first ring groove 531. The grooved fixed ring 53 is provided with an input hole 532 connected to the first ring groove 531. The rotating ring 52, the rotating grooved ring 54 and the cleaning pipe 55 rotate through the rotating structure; in the use state, the input hole 532 is connected to the pressurized water or compressed air through the pipeline, so that the filter screen 13 needs to be cleaned and backwashed. Since the filter screen 13 is fixed, and the cleaning pipe 55 in this embodiment is rotating, the filter screen 13 can be backwashed and cleaned more completely and comprehensively, and the solid-liquid separation effect of the material is further improved.

[0046] In this embodiment, see Figure 8 There are two or three cleaning pipes 55, and the pressurized water or compressed air introduced from the input hole 532 enters the annular cavity surrounded by the first annular groove 531 and the second annular groove 541. Since the cleaning pipe 55 is connected to the first annular groove 531, the pressurized water or compressed air in the annular cavity enters each cleaning pipe 55, and is then sprayed out from the nozzle 551.

[0047] Further, Figure 8 In the embodiment, a ring-shaped sealing groove 543 is provided on the side of the second annular groove 541 that contacts the grooved fixing ring 53 , and a sealing ring 544 is installed in the sealing groove 543 , thereby improving the sealing performance between the grooved fixing ring 53 and the rotating grooved ring 54 .

[0048] In this embodiment, see Figure 8 The rotating structure includes a driver 56 and a ring gear 542 arranged on the outer circumference of the rotating grooved ring 54. The driver 56 is installed outside the filter box 11. The input shaft of the driver 56 extends into the filter box 11 and is installed with a gear 561. The gear 561 is meshed with the ring gear 542 for transmission. The driver 56 adopts a reduction motor.

[0049] The method for using the high-efficiency filtering solid-liquid separation agricultural machinery equipment of the present invention is as follows: When the motor of the solid-liquid separator 10 drives the auger 20 to rotate, the material between the auger 20 and the filter screen 13 is squeezed, the liquid in the material close to the filter screen is filtered and discharged through the filter screen 13, and the liquid in the material far from the filter screen enters the central axis 21 through the filter hole 211 on the central axis 21, and is finally discharged from the drain port, thereby improving the solid-liquid separation effect.

[0050] When the auger 20 rotates, the scraper device 40 does not rotate, so that the interior of the central shaft 21 is cleaned by the scraper 42 to prevent the sediment from clogging the filter hole 211, and the fallen sediment is carried out of the discharge port along with the liquid flow.

[0051] If there are particles, such as sand, blocking the filter hole 211, the collection box 30 and the scraper device 40 are removed when not in operation, and then a high-pressure water pipe and a compressed air pipe are connected through the discharge port of the central axis 21 to back-blow the filter hole 211 to remove the particles blocking the filter hole 211.

[0052] The cutting portion 221 on the spiral blade 22 of the auger 20 is similar to a knife edge. When the auger 20 rotates, the cutting portion 221 cuts off the plant fibers entangled in the filter screen 13, making it easier for the plant fibers to escape from the filter screen 13, thereby passing through the filter screen 13 and improving the solid-liquid separation effect. In addition, since the spiral blade 22 is provided with a deformation seam 223, the spiral blade 22 can be slightly deformed toward the feed side when squeezing the material, so that the cutting portion 221 is deformed toward the feed side, reducing the distance between the cutting portion 221 and the inside of the filter screen 13, so that the plant fibers inside the filter screen 13 are cut more cleanly.

[0053] A slag cleaning device 50 is also provided on the outside of the auger 20. When it is not in operation, the driver 56 is started to drive the gear 561 to rotate, thereby driving the rotating grooved ring 54 to rotate, thereby driving the cleaning pipe 55 to rotate. Since the nozzle 551 is facing the filter screen 13, pressurized water or compressed air is introduced through the input hole 532, thereby rotating the filter screen 13 for complete and comprehensive backwash cleaning, thereby further improving the solid-liquid separation effect of the material.
