Description

Technical Field

[0001] This utility model relates to the technical field of impurity separation equipment, specifically to an impurity separation device for cleaning chemical fiber raw materials. Background Technology

[0002] In the production of synthetic fibers, the cleanliness of raw materials has a crucial impact on the quality of the final product. To improve the quality of synthetic fibers, it is necessary to thoroughly clean the raw materials to remove impurities and particulate matter.

[0003] Traditional impurity separation devices typically employ filtration to achieve this purpose. The mixed chemical fiber raw material liquor is passed downwards through the filter, where the filter medium traps particulate matter and impurities, trapping them at the top while the clean liquid flows out. However, this traditional filtration method has significant drawbacks. First, as the filtration process continues, more and more impurities accumulate on the filter, slowing down the filtration speed and reducing efficiency. Second, when the filter becomes heavily contaminated with impurities, it must be shut down for cleaning or replacement of the filter medium. This not only increases operational complexity but also significantly reduces production efficiency. Furthermore, frequent shutdowns for cleaning increase production costs and impact the stability of the production process.

[0004] Therefore, developing a new type of impurity separation device can effectively solve the problems existing in the current technology, realize continuous operation and efficient filtration, and is of great significance for improving the automation level and economic benefits of chemical fiber production. Summary of the Invention

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] An impurity separation device for cleaning chemical fiber raw materials, comprising:

[0007] A separation tank, wherein a feed pipe is connected to one side of the separation tank and a drain pipe is connected to the other side of the separation tank, and an overflow port is provided on the side wall of the separation tank above the drain pipe;

[0008] A zigzag plate is fixed between the inner sidewalls of the separation tank. The zigzag plate consists of an inclined section and a horizontal section. The horizontal section has a rectangular channel. The connection position between the feed pipe and the separation tank is located below the inclined section, and the overflow port is located above the horizontal section.

[0009] A filtration mechanism is disposed within the rectangular channel, and the filtration mechanism is detachable.

[0010] A water-pressing mechanism is used to press raw material liquid into a filtration mechanism. The water-pressing mechanism includes a fixed cylinder that is fixedly embedded in the inclined section of the folded plate. A hydraulic cylinder is installed on the top of the fixed cylinder. The piston end of the hydraulic cylinder is connected to a squeezing column, which is movably disposed inside the fixed cylinder.

[0011] Furthermore, the filtration mechanism includes a rectangular frame placed on the horizontal section of the folded plate, a mounting box is fixedly embedded in the hollow part of the middle of the rectangular frame, water passage holes are evenly distributed on the upper and lower sides of the mounting box, block activated carbon is provided inside the mounting box, and filter screens are fixed at equal intervals at the bottom of the rectangular frame, with the bottom end of the filter screen penetrating through a rectangular channel and abutting against the bottom of the separation tank.

[0012] Furthermore, one side of the mounting box has an open structure.

[0013] Furthermore, lifting plates are fixed on both sides of the top of the rectangular frame, and a clamping member is provided on one side of the fixed cylinder, the clamping member being used to clamp and fix the lifting plates.

[0014] Furthermore, the clamping member includes a C-shaped plate fixed to the outer wall of the fixed cylinder. A rectangular notch is constructed above the side of the C-shaped plate away from the fixed cylinder, and an installation rod is fixed between the inner walls of the rectangular notch. A torsion spring is sleeved in the middle of the installation rod, and extrusion plates are rotatably connected to both sides of the installation rod. One end of the torsion spring abuts against the inner wall of the C-shaped plate, and the other end abuts against the top of the extrusion plate.

[0015] Furthermore, the extrusion column has a hollow structure and its upper end is conical.

[0016] Furthermore, a one-way valve is installed on the feed pipe near the separation tank.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention utilizes a water-pressing mechanism to squeeze the liquid in the tank, causing the liquid level to rise and pass through a rectangular channel. The filtration mechanism can effectively intercept particulate matter and impurities, allowing clean liquid to pass smoothly and flow out from the overflow port. Due to gravity, particulate matter cannot adhere to the filtration device, thus eliminating the need for frequent replacement or cleaning of the filtration device. This further reduces downtime and improves production efficiency, making it highly practical.

[0019] The filter mechanism of this utility model adopts a multi-stage filtration mechanism, which can significantly improve the filtration effect. In addition, the detachable design of the filter mechanism makes maintenance and replacement simple and quick, reducing the difficulty of operation and maintenance costs. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] This application provides an impurity separation device for cleaning chemical fiber raw materials, mainly addressing the problem in existing technologies where, as the filtration process progresses, more and more impurities accumulate on the filter device, leading to a slowdown in filtration speed and a decrease in filtration efficiency. Secondly, when the filter device is adsorbed or covered with a large amount of impurities, it must be shut down for cleaning or replacement of the filter media. This not only increases operational complexity but also significantly reduces production efficiency. Furthermore, frequent shutdowns for cleaning increase production costs. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-5 Please provide a detailed explanation:

[0028] An impurity separation device for cleaning chemical fiber raw materials, comprising:

[0029] Separation tank 1, with a feed pipe 101 connected to one side of the separation tank 1 and a drain pipe 102 connected to the other side of the separation tank 1. An overflow port 103 is provided on the side wall of the separation tank 1 above the drain pipe 102.

[0030] The folded plate 2 is fixed between the inner side walls of the separation tank 1. The folded plate 2 consists of an inclined section and a horizontal section. The horizontal section has a rectangular channel 201. The connection position between the feed pipe 101 and the separation tank 1 is located below the inclined section, and the overflow port 103 is located above the horizontal section.

[0031] The filter mechanism 3 is set inside the rectangular channel 201. The filter mechanism 3 is detachable. The filter mechanism 3 includes a rectangular frame 301 placed on the horizontal section of the folded plate 2. A mounting box 302 is fixedly embedded in the hollow part of the middle of the rectangular frame 301. Water passage holes 3021 are evenly distributed on the upper and lower sides of the mounting box 302. Block activated carbon 303 is set inside the mounting box 302. Filter screens 304 are fixed at equal intervals at the bottom of the rectangular frame 301. The bottom end of the filter screen 304 penetrates the rectangular channel 201 and abuts against the bottom of the separation tank 1.

[0032] The water pressing mechanism 4 is used to press the raw material liquid into the filter mechanism 3. The water pressing mechanism 4 includes a fixed cylinder 401 fixedly embedded in the inclined section of the folded plate 2. A hydraulic cylinder 402 is installed on the top of the fixed cylinder 401. The piston end of the hydraulic cylinder 402 is connected to a squeezing column 403. The squeezing column 403 is movably arranged inside the fixed cylinder 401.

[0033] Workflow Description

[0034] Raw material input: The chemical fiber raw material mixed with impurities is transported into the separation tank 1 through the feed pipe 101;

[0035] Liquid level rise: The water pressure mechanism 4 is activated to squeeze the chemical fiber raw material mixture in the separation tank 1, causing the liquid level to rise;

[0036] Filtration process: As the liquid level rises, the chemical fiber raw material mixture passes through the rectangular channel 201. At this time, the filtration mechanism 3 set in the rectangular channel 201 starts to work, intercepting particulate matter and impurities, allowing the clean liquid to pass through smoothly. The filter screen 304 can perform preliminary filtration of the chemical fiber raw material, and the block activated carbon 303 can perform deep filtration of the chemical fiber raw material. The multi-stage filtration mechanism has a better filtration effect.

[0037] Cleaning liquid collection: The filtered clean chemical fiber raw material flows out from the overflow port 103 and is collected for subsequent use;

[0038] Impurity discharge: Particles or impurities remaining at the bottom of the separation tank 1 are discharged through the drain pipe 102.

[0039] This impurity separation device for cleaning chemical fiber raw materials uses a water pressure mechanism 4 to squeeze the liquid in the tank, causing the liquid level to rise and pass through a rectangular channel 201. The filter mechanism 3 can effectively intercept particulate matter and impurities, allowing the clean liquid to pass smoothly and flow out from the overflow port 103. Due to gravity, particulate matter cannot adhere to the filter device, so there is no need to frequently replace or clean the filter device, further reducing downtime and improving production efficiency, making it highly practical.

[0040] like Figure 5 As shown, in some embodiments, one side of the mounting box 302 is an open structure. More specifically, since activated carbon gradually becomes saturated during use, its filtration effect will decrease accordingly. Therefore, it needs to be regenerated or replaced regularly to ensure continuous and efficient filtration performance. The open structure allows staff to easily remove the old activated carbon and put in the new activated carbon without using special tools or performing complicated disassembly operations, thereby simplifying the maintenance process and reducing maintenance costs.

[0041] like Figure 2 As shown, in some embodiments, lifting plates 305 are fixed on both sides of the top of the rectangular frame 301, and a clamping member 5 is provided on one side of the fixed cylinder 401. The clamping member 5 is used to clamp and fix the lifting plate 305. More specifically, the design of the lifting plate 305 facilitates the removal and installation of the filter mechanism 3 by the operator during daily operation. By simply lifting the lifting plate 305, the operator can easily remove the entire filter mechanism 3 from the device without using complicated tools or performing cumbersome operating procedures. This not only improves work efficiency but also reduces the difficulty of operation, making maintenance work more convenient and efficient. The clamping member 5 is specifically used to clamp and fix the lifting plate 305, thereby ensuring that the filter mechanism 3 will not loosen or shift during the entire operation process. This design not only improves the stability and reliability of the device but also ensures the consistency and efficiency of the filtration effect. Even during long-term operation, the filter mechanism 3 can maintain its original position and state.

[0042] like Figure 2As shown, in some embodiments, the clamping member 5 includes a C-shaped plate 501 fixed to the outer wall of the fixed cylinder 401. A rectangular notch is constructed above the side of the C-shaped plate 501 away from the fixed cylinder 401, and an installation rod 502 is fixed between the inner walls of the rectangular notch. A torsion spring 503 is sleeved in the middle of the installation rod 502, and a pressing plate 504 is rotatably connected to both sides of the installation rod 502. One end of the torsion spring 503 abuts against the inner wall of the C-shaped plate 501, and the other end abuts against the top of the pressing plate 504. More specifically, one end of the torsion spring 503 abuts against the inner wall of the C-shaped plate 501, and the other end abuts against the top of the pressing plate 504. This arrangement allows the torsion spring 503 to provide continuous elastic force to the pressing plate 504. Under the elastic force of the torsion spring 503, the pressing plate 504 can always maintain pressure on the lifting plate 305, thereby completing the clamping work.

[0043] like Figure 4 As shown, in some embodiments, the extrusion column 403 has a hollow structure and its upper end is conical. More specifically, the extrusion column 403 adopts a hollow structure. This design not only reduces the overall weight and material cost, but also reduces energy consumption. The conical design makes it less likely for impurities or liquids to remain at the top. Because the conical structure has a good self-cleaning function, when liquid flows through the top of the cone, it can flow down smoothly without leaving dead corners or residues.

[0044] like Figure 1 As shown, in some embodiments, a one-way valve 1011 is installed near the separation tank 1 on the feed pipe 101. More specifically, when the water pressing mechanism 4 starts working, the hydraulic cylinder 402 pushes the extrusion column 403 downward to extrude the chemical fiber raw material mixture in the separation tank 1. At this time, due to the action of the one-way valve 101, the chemical fiber raw material cannot flow back to the raw material source or other parts through the feed pipe 101, but is restricted in the separation tank 1 to continue to be filtered and processed.

[0045] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
