Description

Technical Field

[0001] The present application relates to the technical field of solid-liquid separation, and in particular to a solid-liquid separation device. Background Art

[0002] There are various main types of solid-liquid separation equipment. Some use the density difference between solid particles and liquid to allow solid particles to naturally settle to the bottom of the container under the action of gravity, thereby achieving solid-liquid separation; others use media (such as filter screens, filter cloths, etc.) to retain solid particles on their surface, thereby achieving solid-liquid separation.

[0003] In the related technology, as described in Chinese patent application number CN201911375256.X, after the material enters the trough-type filter body, the reciprocating circular motion of the two groups of movable bars A and B is used to ensure the smoothness of the filter seam, so that the filtrate is discharged from the filter seam into the filtrate trough as much as possible, and the remaining material overflows from the upper edge of the rear wall.

[0004] With respect to the above-mentioned related technologies, the tank-type filter is used as a tank body of a flocculation mixing tank. The bottom of the tank-type filter device is the main filtration channel, but it is easy for materials to be retained and the filter seams to be blocked by precipitated sludge. Summary of the invention

[0005] In order to solve the above technical problems, the present application provides a solid-liquid separation device.

[0006] The present application provides a solid-liquid separation device, which adopts the following technical solution: A solid-liquid separation device comprises a conveying platform with a filter, a baffle installed above the conveying platform, and a driving assembly, wherein the length direction of the baffle extends along the width direction of the conveying platform, the baffle is provided with one or more baffles, the baffle is provided with a protrusion for cutting into materials, and the protrusions are distributed in multiple intervals along the length direction of the baffle, and the driving assembly is used to drive the baffle to perform reciprocating circular motion downward, forward, upward, and backward. After the protrusion cuts into the material downward, it moves forward in the conveying direction and leaves the material by moving upward, so that the protrusion intermittently cuts into the material on the conveying platform.

[0007] By adopting the above technical solution, the driving component drives the baffle plate to perform reciprocating circular motion downward, forward, upward and backward. During the period when the baffle plate is in contact with the material, the material is continuously piled up to form a baffle dam body, so that the baffle plate can block the water accumulated on the surface of the material while also causing the material to be piled up into multiple baffle dam bodies at intervals along the direction of the conveying platform. The baffle dam bodies can have a certain baffle effect, and with the reciprocating circular motion of the baffle plate, the accumulation of the baffle dam bodies forms a dynamic balance; when the protruding portion of the baffle plate cuts into the material, the protruding portion can also scratch grooves on the material, causing the accumulated water in the material to gather in the grooves and be filtered out from the conveying platform, thereby improving the filtration effect of the conveying platform.

[0008] Optionally, the conveying platform is arranged to be tilted downward from the starting end to the end end, so that the material placed on the conveying platform can flow forward along the conveying direction of the conveying platform.

[0009] The adoption of the above technical solution helps the natural flow of materials during the transportation process, reduces the accumulation and retention of materials on the transportation platform, and improves the transportation efficiency and solid-liquid separation effect.

[0010] Optionally, at least two groups of the baffles are provided, and the protrusions of the baffles are staggered with each other, so that the grooves drawn by the protrusions on the material are at different positions.

[0011] By adopting the above technical solution, due to the mutual misalignment of the protrusions, when the two groups of baffles come into contact with the material and move relative to each other, the positions of the grooves drawn on the material by the protrusions of each group of baffles are different, which helps to further speed up the water filtration speed of the material and avoid repeatedly drawing the same groove at the same position.

[0012] Optionally, the protrusion is bent toward the conveying direction of the conveying platform to reduce the adhesion of materials to the protrusion.

[0013] By adopting the above technical solution, when the protrusion leaves the material, the material leaves the protrusion smoothly.

[0014] Optionally, the driving component includes: a set of first drive shafts, having two or more; A driving source, mounted on the conveying platform, for driving a group of the first driving shafts to rotate at the same speed and in the same direction; A guide plate group, comprising two or more guide plates, the spoiler being fixedly connected to the guide plate group, and the number of spoilers connected to the guide plate group comprising one or more; Among them, the guide plate is connected to a group of the first driving shafts through an eccentric mechanism, so that when the first driving shaft rotates, it drives the guide plate to perform circular motion, and the spoiler connected to the guide plate group performs downward, forward, upward and backward circular motion.

[0015] Optionally, the guide plate groups are provided in two or more groups, and the eccentric mechanisms of different guide plate groups have different eccentric directions relative to the first drive shaft, so that the movement trajectories of the spoilers of different groups are staggered.

[0016] By adopting the above technical solution, the solid-liquid separation efficiency is improved, and it also helps to avoid local accumulation and retention of materials during the transportation process.

[0017] Optionally, the conveying platform is formed by two groups of movable bars stacked alternately; adjacent movable bars in the same group are separated by gaskets, and the thickness of the gaskets is greater than the thickness of the movable bars in the other group, so as to form filter gaps; The conveying platform comprises a guide grid and a group of second driving shafts, wherein the group of second driving shafts is connected to the guide grid through an eccentric mechanism, and the guide grid is connected to the movable grid of the same group through a series rod; The driving source includes a motor and a gear transmission group. The motor drives a group of the first driving shafts and a group of the second driving shafts to move synchronously through the gear transmission group.

[0018] By adopting the above technical solution, a group of first drive shafts and a group of second drive shafts share a driving source, which can make the mechanical structure more compact and improve space utilization.

[0019] Optionally, a filtrate collecting plate trough is installed below the conveying platform, and the filtrate collecting plate trough is arranged to be inclined downward.

[0020] By adopting the above technical scheme, the filtrate collecting plate trough can collect the filtrate and discharge the filtrate uniformly. When the filtrate flows along the filtrate collecting plate trough, more filtrate falls from the starting end of the conveying platform, which can also flush the mud residue on the filtrate collecting plate trough.

[0021] Optionally, there are at least two groups of conveying platforms, and among two adjacent groups of conveying platforms, the end of one group of conveying platforms is located above the beginning of the other group of conveying platforms; the filtrate collection plate troughs and the conveying platforms are arranged correspondingly, and among two adjacent groups of filtrate collection plate troughs, the end of one filtrate collection plate trough and the beginning of the other filtrate collection plate trough are stacked.

[0022] By adopting the above technical solution, multiple groups of conveying platforms are set up to extend the time for solid-liquid separation of materials. The conveying platform is equipped with a baffle, so that the material can always leave smoothly and stably, and the filtrate can also flush the mud residue downward along the inclined state and take the mud residue away together.

[0023] Optionally, it also includes a flocculation mixing tank, which is provided with a distribution mechanism at its discharge port, and is located above the starting end of the conveying platform. The distribution mechanism includes a distribution box, a baffle and an overflow plate. The distribution box has a feed port and a discharge port. There is a gap between the baffle and the bottom of the distribution box, and there is a gap between the overflow plate and the top wall of the distribution box. The material passes through the baffle and the overflow plate in turn. The overflow plate is a bent plate-shaped structure. The overflow plate has a first inclined surface and a second inclined surface, and the first inclined surface faces the feed port.

[0024] By adopting the above technical solution, after the material is received by the distribution mechanism, the material is first spread in the distribution box, and the baffle has a shielding effect on the falling material to reduce the splashing of the material. The material can leave the distribution box only after it overflows the overflow plate. The first inclined surface can guide the material to leave the distribution box and reduce the accumulation of the material at the bottom of the overflow plate. The second inclined surface further buffers the material so that the material can fall smoothly onto the conveying platform.

[0025] In summary, the present application includes at least one of the following beneficial effects: 1. The material moves along with the movement of the conveying platform. When the conveying platform tilts downward to convey the material, the material itself also has a flow speed, making the filter residue after solid-liquid separation move forward more smoothly; 2. The forward compound-moving baffle contacts the surface of the material, and the baffle can block the water on the surface of the material. During the contact between the material and the baffle, the material can also pile up to form a baffle dam, reducing the flow rate of the material itself. In addition, the protrusion plows grooves on the material, and the water accumulated in the material can gather in the grooves, which can not only make the filter residue move forward smoothly, but also speed up the water filtration of the material; 3. The material is buffered by the material distribution mechanism and then spread on the conveying platform, which can make the material more evenly distributed on the conveying platform.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1 -Attached Figure 7 This application is described in further detail.

[0029] The embodiment of the present application discloses a solid-liquid separation device.

[0030] Reference Figure 1 and Figure 2 A solid-liquid separation device includes a conveying platform 20 with a filtering function, a baffle 40 installed above the conveying platform 20, and a driving assembly 50. The length direction of the baffle 40 extends along the width direction of the conveying platform 20. The baffle 40 is provided with a plurality of protrusions 41 for cutting into materials at intervals along its length, and a gap is left between two adjacent protrusions 41 for materials to pass through. The driving assembly 50 is used to drive the baffle 40 to perform reciprocating circular motion downward, forward, upward, and backward, and to leave the material by moving upward, so that the protrusions 41 intermittently cut into the material on the conveying platform 20.

[0031] The spoiler 40 and the protrusion 41 of the embodiment of the present application are combined into a plowing structure, and the end of the protrusion 41 is serrated. The protrusion 41 is bent toward the conveying direction of the conveying platform 20 to reduce the adhesion of materials to the protrusion 41. In terms of spatial layout, the protrusion 41 of the spoiler 40 may also be arranged in a wavy shape or other irregular shapes to ensure that a better dislocation effect and gully position difference can be achieved during the material processing process.

[0032] There is one or more spoiler 40. When there is more than one spoiler 40, the protrusions 41 on the spoiler 40 are mutually staggered, and when all the protrusions 41 cut into the material, the grooves drawn by the protrusions 41 on the material are at different positions.

[0033] The conveying platform 20 is arranged to be tilted downward from the beginning to the end, so that the material placed on the conveying platform 20 can flow forward along the conveying direction of the conveying platform 20. The baffle 40 makes a reciprocating circular motion downward, forward, upward, and backward, and the protrusion 41 cuts into the material. The baffle 40 contacts the surface of the material, and the baffle 40 can have a certain flow blocking effect on the material, especially for the water that has not been filtered on the material. During the contact between the baffle 40 and the material, the material is piled up to form a baffle dam body, and the baffle dam body can also have a certain flow blocking effect. And with the reciprocating circular motion of the baffle 40, the accumulation of the baffle dam body forms a dynamic balance, so that the material can move forward smoothly along the conveying platform 20 tilted downward. At the same time, the protrusion 41 contacts the material, plowing a series of gullies on the material laid flat on the conveying platform 20, and the accumulated water gathers in the gullies, and then seeps out from the filter seam near the gullies, greatly accelerating the water filtering speed of the conveying platform 20.

[0034] Reference Figure 2 The driving assembly 50 includes a group of first driving shafts 51, a driving source 53 and a group of guide plates 52. The driving source 53 is installed on the conveying platform 20; the spoiler 40 is fixedly connected to the guide plate 52 group through a connecting rod 42. The number of spoilers 40 connected to the guide plate 52 group includes one or more. The guide plate 52 is connected to a group of first driving shafts 51 through an eccentric mechanism 60. The driving source 53 drives a group of first driving shafts 51 to rotate at the same speed and in the same direction, so that when the first driving shaft 51 rotates, it drives a group of guide plates 52 to perform circular motion. The spoiler 40 connected to the guide plate 52 performs reciprocating circular motion downward, forward, upward and backward.

[0035] Reference Figure 2 , a group of first drive shafts 51 has two or more, and a group of first drive shafts 51 in the embodiment of the present application is two. There are two or more groups of guide plates 52, and the guide plates 52 in the embodiment of the present application are set as two groups, and each group of guide plates 52 is connected to two spoilers 40. The two groups of guide plates 52 share a group of first drive shafts 51, and the eccentric mechanisms 60 of the two groups of guide plates 52 have different eccentric directions relative to the first drive shaft 51, so that the movement trajectories of spoilers 40 in different groups are staggered.

[0036] Reference Figure 3The conveying platform 20 is formed by two groups of movable bars 21 stacked alternately, and baffles 22 are arranged on both sides of the conveying platform 20. Each adjacent movable bar 21 in the same group of movable bars 21 is separated by a gasket, and the thickness of the gasket is greater than the thickness of the other group of movable bars 21, thereby forming a filter seam. The conveying platform 20 includes a guide bar 23 and a group of second drive shafts 24, and a group of second drive shafts 24 is connected to the guide bar 23 through an eccentric mechanism 60. A group of movable bars 21 corresponds to two guide bars 23, and the two guide bars 23 are connected to the movable bars 21 of the same group through a series rod 25. When the second drive shaft 24 rotates, a group of movable bars 21 performs a reciprocating circular motion downward, forward, upward, and backward.

[0037] The two groups of movable bars 21 share a second drive shaft 24 , and the eccentric mechanisms 60 of the two groups of movable bars 21 have different eccentric directions relative to the second drive shaft 24 , so that the movement trajectories of the two groups of movable bars 21 intersect, so that the conveying platform 20 can convey materials smoothly.

[0038] Specifically, the eccentric mechanism 60 is an eccentric bearing, the guide plate 52 and the outer ring of the eccentric bearing are fixedly connected, the first drive shaft 51 and the inner ring of the eccentric bearing on the guide plate 52 are fixedly connected; the guide bar 23 and the outer ring of the eccentric bearing are fixedly connected, and the second drive shaft 24 and the inner ring of the eccentric bearing on the guide bar 23 are fixedly connected.

[0039] Reference Figure 4 A group of first drive shafts 51 and a group of second drive shafts 24 are arranged in parallel, and the driving source 53 includes a motor and a gear transmission group. The motor drives a group of first drive shafts 51 and a group of drive shafts to move synchronously through the gear transmission group. The gear transmission assembly includes a driving gear and a driven gear. The output shaft of the motor is coaxially fixedly connected to the driving gear, and the driven gear is coaxially fixedly connected to the first drive shaft 51 and the second drive shaft 24. When the motor is turned on, the driving gear rotates, thereby driving a group of first drive shafts 51 and a group of second drive shafts 24 to move synchronously.

[0040] Reference Figure 1 A filtrate collecting plate trough 30 is installed below the conveying platform 20. The filtrate collecting plate trough 30 is arranged to be inclined downward, so as to facilitate the uniform discharge of the filtered water filtered by the conveying platform 20. The conveying platform 20 of the embodiment of the present application is provided with two groups, and the end of one group of conveying platforms 20 is located above the beginning of the other group of conveying platforms 20.

[0041] Reference Figure 1 and Figure 5The filtrate collecting plate trough 30 and the conveying platform 20 are arranged correspondingly, and the end of one filtrate collecting plate trough 30 is stacked with the beginning of another filtrate collecting plate trough 30. The conveying platform 20 at a higher position has more filtrate, and when the filtrate flows along the inclined filtrate collecting plate trough 30, the filtrate can flush the mud residue on the filtrate collecting plate trough 30.

[0042] The conveying platform 20 can also use a conveyor belt with distributed water filtering holes. The conveyor belt is sleeved with active rollers and transmission rollers, and a motor is used to drive the active roller to rotate. The conveyor belt is a prior art and will not be described in detail in this application.

[0043] Reference Figure 1 The solid-liquid separation device also includes a flocculation mixing tank 10 . The flocculation mixing tank 10 is provided with a material distribution mechanism 70 at its own discharge port. The material distribution mechanism 70 is located above the starting end of the conveying platform 20 .

[0044] Reference Figure 6 and Figure 7 The material distributing mechanism 70 includes a material distributing box 71, a baffle 72 and an overflow plate 73. There is a gap between the baffle 72 and the lower surface of the material distributing box 71, and there is a gap between the overflow plate 73 and the upper surface of the material distributing box 71. The material distributing box 71 has a feed inlet and a discharge port. The feed inlet is located on the upper end surface of the material distributing box 71, and the discharge port is located on the side wall of the material distributing box 71. The baffle 72 is close to the feed inlet, and the sludge passes through the baffle 72 and the overflow plate 73 in turn. When the material enters the material distributing box 71, the baffle 72 has a preliminary buffering effect on the material. The material is first spread in the material distributing box 71, and only after the material overflows the overflow plate 73 can it leave the material distributing box 71 through the discharge port and flow into the conveying platform 20.

[0045] The overflow plate 73 is a bent plate-shaped structure, and has a first inclined surface and a second inclined surface, with the first inclined surface facing the feed port. The first inclined surface is used to guide the material to move in the direction of the discharge port. As the material is continuously conveyed into the material distribution box 71, the material can also have an upward flushing force, reducing the accumulation of some materials at the bottom of the overflow plate 73. The second inclined surface further buffers and guides the material. Through the cooperation of the material distribution box 71, the baffle 72 and the overflow plate 73, the material distribution mechanism 70 has a buffering function for the material before distributing the material to the conveying platform 20.

[0046] The implementation principle of a solid-liquid separation device in the embodiment of the present application is: The sludge and the flocculant are fully mixed and stirred in the flocculation mixing tank 10 to form flocs, which are then laid on the conveying platform 20 through the material distribution mechanism 70. The movement trajectories of the two sets of movable bars 21 are staggered, and the materials can be smoothly pushed forward for transportation in conjunction with the inclination angle of the conveying platform 20 itself. At the same time, the filtering gaps formed by the movable bars 21 can be kept unobstructed, ensuring that the water filtering process is smooth and unobstructed. The filtered water flows to a lower place through the filtrate collecting plate trough 30 at the bottom, and the filtrate of multiple conveying platforms 20 can be discharged uniformly. In addition, the baffle 40 makes a reciprocating circular motion downward, forward, upward and backward along the material conveying direction, and the protrusion 41 can cut into the flat material surface. The baffle 40 itself has a certain baffle effect. During the contact between the baffle 40 and the material surface, the material pile forms a baffle dam body, and with the reciprocating circular motion of the baffle 40, the accumulation of the baffle dam body forms a dynamic balance. The baffle dam body can also play a baffle effect, reduce the flow speed of the material itself, and try to make the material move with the movement of the downward inclined conveying platform 20, and the protrusion 41 can also plow grooves in the flat material, greatly accelerating the water filtration speed; the baffle 40 staggered front and back not only increases the number of baffle dam bodies, but also makes the grooves plowed by the material on the conveying platform 20 more uniform, and to a certain extent, pushes the filter residue forward, so that the entire device can achieve smoother and faster water filtration, and the filter residue moves forward more smoothly.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
