Description

Technical Field

[0001] This utility model relates to the field of filter press equipment technology, and in particular to a cutting waste liquid filter residue treatment system. Background Technology

[0002] Silicon wafer factories generate a large amount of cutting waste fluid when cutting silicon wafers. This cutting waste fluid contains substances such as oil and heavy metals. Direct discharge of such fluid will pollute the ecological environment and requires treatment.

[0003] The treatment process for cutting fluid includes filtration. Filtration produces filter residue. This residue contains metal powder, which has recycling value. However, it also contains a large amount of water. This high-moisture residue is highly adhesive and easily adheres to conveyor belts, transport vehicles, and the inner walls of pipes, causing blockages and slippage, requiring frequent cleaning of transport equipment. Furthermore, the high water content of the residue also makes it highly fluid, increasing the risk of leakage during transport and polluting roads and the surrounding environment.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a cutting waste liquid filter residue treatment system to facilitate the transportation of filter residue.

[0006] The technical solution of this utility model is as follows:

[0007] The cutting waste fluid filter residue treatment system includes:

[0008] The dewatering mechanism includes a frame, a filter roller assembly mounted on the frame, and a first filter cloth and a second filter cloth arranged around the filter roller assembly; at least two pressing rollers are arranged in parallel within the filter roller assembly.

[0009] The material bin has a pressure plate and a push plate inside; the pressure plate is connected to a vertically arranged hydraulic cylinder; the push plate is connected to a horizontally arranged hydraulic cylinder; the movement paths of the pressure plate and the push plate intersect.

[0010] The feeding hopper connects the interior of the dewatering mechanism and the material box;

[0011] The first filter cloth and the second filter cloth pass through the gap between adjacent rolling rollers simultaneously; filter residue is disposed between the first filter cloth and the second filter cloth; after the first filter cloth and the second filter cloth pass through the adjacent rolling rollers, the filter residue between the first filter cloth and the second filter cloth falls into the feeding hopper and enters the material box.

[0012] A further technical solution is that the frame is also provided with a first roller group and a second roller group; the first roller group and the second roller group are respectively provided with guide rollers parallel to the pressing roller; the first filter cloth is wound on the first roller group and the filter press roller group; the second filter cloth is wound on the second roller group and the filter press roller group.

[0013] A further technical solution is that the first roller group and the second roller group are arranged on opposite sides of the filter press roller group; the rotation direction of the guide roller in the first roller group is opposite to the rotation direction of the guide roller in the second roller group.

[0014] A further technical solution is that the pressing rollers in the filter press roller group are arranged in the same plane; two sets of the filter press roller groups are arranged in parallel on the frame; and the pressing rollers between the two sets of the filter press roller groups are staggered.

[0015] A further technical solution is that the frame is also provided with a feed hopper; the outlet of the feed hopper is located between the first filter cloth and the second filter cloth.

[0016] A further technical solution is that the bottom plate of the feeding hopper is inclined; the end of the bottom plate near the dewatering mechanism is higher than the end of the bottom plate near the material box.

[0017] A further technical solution is that the first filter cloth and the second filter cloth begin to move away from each other after passing through the adjacent rolling rollers; the opening of the feeding hopper is located below the position where the first filter cloth and the second filter cloth begin to move away from each other; the outlet of the feeding hopper communicates with the interior of the material box; the opening of the feeding hopper is larger than the outlet of the feeding hopper.

[0018] A further technical solution is that two first protrusions are extended from one surface of the pressure plate; the telescopic rod of the hydraulic cylinder connected to the pressure plate extends between the two first protrusions and is bolted to the first protrusions.

[0019] A further technical solution is that two second protrusions are extended from one surface of the push plate; the telescopic rod of the hydraulic rod connected to the push plate extends between the two second protrusions and is bolted to the second protrusions.

[0020] A further technical solution is to provide an anti-blocking opening at the bottom of the material box, near the end of the hydraulic cylinder connected to the push plate.

[0021] The beneficial technical effects of this utility model are as follows:

[0022] (1) The cutting waste fluid filter residue treatment system of this utility model is equipped with a dewatering mechanism. The dewatering mechanism squeezes out most of the water from the filter residue, reducing its moisture content and thus decreasing its viscosity and fluidity, facilitating its transfer and recycling. A material bin is also provided. The dewatered filter residue enters the material bin along the feeding hopper. A pressure plate squeezes the dewatered filter residue in the bin, pressing it into blocks. A pusher plate then pushes the blocks of filter residue out of the bin. The blocky filter residue is less prone to scattering, resulting in less loss during long-distance transportation.

[0023] (2) Further, two sets of filter press rollers are arranged in parallel on the frame, and the rollers between the two sets of filter press rollers are staggered. When the first filter cloth and the second filter cloth pass through the staggered rollers, the first filter cloth and the second filter cloth are bent at a large angle to fully squeeze the moisture of the filter residue between the first filter cloth and the second filter cloth.

[0024] (3) Furthermore, an anti-clogging port is also added to the bottom of the hopper. After the pusher plate extends in to push the blocky filter cake out of the hopper, it needs to retract and return to its original position. When the pusher plate returns to its original position, it may bring back some of the scattered filter cake. This part of the filter cake that is brought back can be discharged along the anti-clogging port, avoiding the accumulation of filter cake between the pusher plate and the hydraulic cylinder, which would affect the normal operation of the pusher plate.

Therefore, they should not be construed as limitations on this utility model.

[0032] Figure 1 A three-dimensional structural schematic diagram of a cutting waste fluid filter residue treatment system according to an embodiment of the present disclosure is shown. Figure 2 A partially enlarged view of a cutting fluid filter residue treatment system according to an embodiment of the present disclosure is shown at point A. Figure 3 A vertical cross-sectional view of the material bin is shown in a cutting fluid filter residue treatment system according to an embodiment of this disclosure. Please refer to... Figure 1 , Figure 2 and Figure 3 The cutting waste fluid filter residue treatment system includes a dewatering mechanism 1, comprising a frame 11, a filter press roller assembly 15 mounted on the frame 11, and a first filter cloth 12 and a second filter cloth 13 arranged around the filter press roller assembly 15. At least two pressing rollers 151 are arranged in parallel within the filter press roller assembly 15. A material bin 3 contains a pressure plate 4 and a push plate 5. The pressure plate 4 is connected to a vertically arranged hydraulic cylinder 42. The push plate 5 is connected to a horizontally arranged hydraulic cylinder 42. The movement paths of the pressure plate 4 and the push plate 5 intersect. A support 32 is mounted on the material bin 3, and the hydraulic cylinders 42 connecting the pressure plate 4 are mounted on the support 32. A feeding hopper 2 connects the dewatering mechanism 1 and the interior of the material bin 3.

[0033] In this process, the first filter cloth 12 and the second filter cloth 13 simultaneously pass through the gap between adjacent pressing rollers 151. The filter residue is placed between the first filter cloth 12 and the second filter cloth 13. As the first filter cloth 12 and the second filter cloth 13 pass through the adjacent pressing rollers 151, the filter residue between the first filter cloth 12 and the second filter cloth 13 is squeezed by the adjacent pressing rollers 151 to expel water. After the water is expelled, the moisture content of the filter residue decreases, thereby reducing the stickiness and fluidity of the filter residue. This facilitates the transfer and recycling of the filter residue. After the first filter cloth 12 and the second filter cloth 13 pass through the adjacent pressing rollers 151, the filter residue between the first filter cloth 12 and the second filter cloth 13 falls into the feeding hopper 2 and enters the material box 3. The dehydrated filter residue enters the material box 3 along the feeding hopper 2, where the pressure plate 4 squeezes the dehydrated filter residue in the material box 3, pressing the filter residue into blocks, and the push plate 5 pushes the blocks of filter residue out of the material box 3. The blocky filter residue is less likely to scatter, resulting in less loss during long-distance transportation.

[0034] Specifically, along the path of the pusher plate 5, the material box 3 has an opening and a door plate 31. When the pressure plate 4 squeezes the filter residue, the door plate 31 closes, and the filter residue is squeezed into blocks within the material box 3. When the pusher plate 5 pushes out the filter residue, the door plate 31 opens, and the filter residue is pushed out of the material box 3 by the pusher plate 5. The opening on the box body connects to the feeding hopper 2. A roller shutter door plate 31 (not shown in the figure) is provided at this opening position. One end of the roller shutter door plate 31 is connected to the material box 3, and the other end of the roller shutter door plate 31 is connected to the pressure plate 4. When the pressure plate 4 falls to squeeze the filter residue, the roller shutter door plate 31 falls to prevent the filter residue from falling above the pressure plate 4. When the pressure plate 4 moves upward, the roller shutter door plate 31 opens. When the pusher plate 5 pushes out the blocky filter residue, the upward movement of the pressure plate 4 is not yet complete, and at this time the roller shutter door plate 31 is still disconnected from the feeding hopper 2 and the box body. The roller shutter door plate 31 only opens completely after the pusher plate 5 retracts, preventing the filter residue from falling behind the pusher plate 5.

[0035] Please refer to Figure 1 and Figure 2 The frame 11 is also equipped with a first roller group 14 and a second roller group 16. Guide rollers 141, parallel to the pressing roller 151, are respectively installed within the first roller group 14 and the second roller group 16. A first filter cloth 12 is wound around the first roller group 14 and the filter press roller group 15. A second filter cloth 13 is wound around the second roller group 16 and the filter press roller group 15. The first roller group 14 and the second roller group 16 are located on opposite sides of the filter press roller group 15. The rotation direction of the guide rollers 141 in the first roller group 14 is opposite to the rotation direction of the guide rollers 141 in the second roller group 16. The first roller group 14, the second roller group 16, and the filter press roller group 15 drive the first filter cloth 12 and the second filter cloth 13 to rotate, thereby causing the filter residue between the first filter cloth 12 and the second filter cloth 13 to pass through the pressing roller 151 and squeeze out the water. Specifically, both the guide roller 141 and the pressing roller 151 are connected to a motor, which drives the guide roller 141 and the pressing roller 151 to rotate.

[0036] Preferably, the pressing rollers 151 within the filter press roller assembly 15 are arranged in the same plane. Two sets of filter press roller assemblies 15 are arranged in parallel on the frame 11. The pressing rollers 151 between the two sets of filter press roller assemblies 15 are staggered. When the first filter cloth 12 and the second filter cloth 13 pass through the staggered pressing rollers 151, the first filter cloth 12 and the second filter cloth 13 are bent at a large angle to fully squeeze out the moisture from the filter residue between the first filter cloth 12 and the second filter cloth 13.

[0037] Please refer to Figure 1 and Figure 2 The frame 11 is also equipped with a feed hopper 17. The outlet of the feed hopper 17 is located between the first filter cloth 12 and the second filter cloth 13. Feeding the filter residue into the feed hopper 17 precisely places the filter residue between the first filter cloth 12 and the second filter cloth 13, which facilitates feeding.

[0038] Preferably, the bottom plate 21 of the feeding hopper 2 is inclined. The end of the bottom plate 21 near the dewatering mechanism 1 is higher than the end of the bottom plate 21 near the material box 3. After the filter residue dewatered on the dewatering mechanism 1 falls into the feeding hopper 2, it automatically slides into the box body along the bottom plate 21 under the action of gravity.

[0039] More preferably, the first filter cloth 12 and the second filter cloth 13 begin to move away from each other after passing through the adjacent pressing rollers 151. The opening of the feeding hopper 2 is located below the position where the first filter cloth 12 and the second filter cloth 13 begin to move away. The dewatered filter cake automatically falls into the feeding hopper 2 without any further operation. The outlet of the feeding hopper 2 connects to the interior of the material box 3. The opening of the feeding hopper 2 is larger than the outlet of the feeding hopper 2 to receive the dewatered filter cake from the dewatering mechanism 1, reducing the probability of filter cake scattering.

[0040] Please refer to Figure 1 and Figure 3 Two first protrusions 41 extend from one surface of the pressure plate 4. The telescopic rod 43 of the hydraulic cylinder 42, which connects to the pressure plate 4, extends between the two first protrusions 41 and is bolted to the first protrusions 41. Specifically, both the first protrusions 41 and the telescopic rod 43 have through holes, and threaded fasteners 44 pass through both the first protrusions 41 and the telescopic rod 43 along the through holes to connect the pressure plate 4 and the hydraulic cylinder 42. The threaded fasteners 44 can be bolts or nuts.

[0041] Preferably, two second protrusions 51 extend from one surface of the push plate 5. A telescopic rod 43, connecting the hydraulic rod of the push plate 5, extends between the two second protrusions 51 and is bolted to the second protrusions 51. Specifically, both the second protrusions 51 and the telescopic rod 43 have through holes, and threaded fasteners 44 pass through both the second protrusions 51 and the telescopic rod 43 along the through holes to connect the pressure plate 4 and the hydraulic cylinder 42. The threaded fasteners 44 can be bolts or nuts.

[0042] More preferably, an anti-clogging port 33 is provided at the bottom of the material box 3, near the end of the hydraulic cylinder 42 connected to the push plate 5. After the push plate 5 extends into the material box 3 to push out the blocky filter cake, it needs to retract to its original position. When the push plate 5 retracts, it may bring back some of the scattered filter cake. This part of the filter cake brought back can be discharged along the anti-clogging port 33, avoiding the accumulation of filter cake between the push plate 5 and the hydraulic cylinder 42, which would affect the normal operation of the push plate 5.

[0043] The specific workflow of this utility model is as follows:

[0044] During filter cake processing, the operator or feeding mechanism feeds the filter cake into the hopper 17. The filter cake entering the hopper 17 falls onto the surface of the first filter cloth 12 near the second filter cloth 13. The motor drives the guide roller 141 and the pressing roller 151 to rotate continuously, and the rotating guide roller 141 and the pressing roller 151 drive the first filter cloth 12 and the second filter cloth 13 to rotate. The first filter cloth 12 rotates around the filter press roller group 15 and the first roller group 14, and the second filter cloth 13 rotates around the filter press roller group 15 and the second roller group 16. As the first filter cloth 12 and the second filter cloth 13 pass through the gap between the adjacent pressing rollers 151, the filter cake between the first filter cloth 12 and the second filter cloth 13 is squeezed out of the water by the pressing rollers 151. After passing through the gap between the adjacent pressing rollers 151, the first filter cloth 12 and the second filter cloth 13 separate, and the filter cake between the first filter cloth 12 and the second filter cloth 13 falls into the feeding hopper 2. The filter cake falling into the feeding hopper 2 slides along the inclined bottom plate 21 into the material box 3. At this time, the hydraulic cylinder 42 drives the pressure plate 4 to fall and squeeze the filter residue in the material box 3, and the filter residue is squeezed into a block shape in the material box 3. Then the door panel 31 is opened, the hydraulic cylinder 42 drives the push plate 5 to move, and the push plate 5 pushes the block-shaped filter residue out of the material box 3.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
