Description

Technical Field

[0001] This application relates to the field of melt filter technology, and in particular to a counter-current melt filter performance improvement device. Background Technology

[0002] In the production of polymer materials such as plastics and synthetic fibers, countercurrent melt filters are key equipment for ensuring melt purity and product quality. With the development of the new materials industry, the market's requirements for the precision and stability of polymer products are becoming increasingly stringent, highlighting the performance shortcomings of traditional countercurrent melt filters.

[0003] In practical use, it has been found that traditional filter cartridges or filter plates lack an effective cleaning mechanism when intercepting impurities and gel particles in the melt. Impurities accumulate on the filter surface to form a filter cake, which leads to a rapid increase in filtration resistance, a significant decrease in melt flow, and consequently a reduction in filtration performance. Therefore, we propose a counter-current melt filter performance enhancement device to solve the above problems. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of existing technologies, such as the accumulation of impurities on the filter surface forming a filter cake, which leads to a rapid increase in filtration resistance, a significant decrease in melt flow rate, and consequently a reduction in filtration performance. Therefore, this application proposes a counter-current melt filter performance enhancement device.

[0010] A further feature of this application is that a unclogging rod is provided on the stirring shaft, and the unclogging rod is located inside the feed pipe.

[0011] By adopting the above technical solution and installing a dredging rod, the feed pipe can be cleared, ensuring that the melt flows smoothly into the filter box. This effectively avoids blockage caused by high-viscosity melt stagnation or solidification in the pipe.

[0012] A further feature of this application is that the gear mechanism includes two bevel gears, and bevel gears are fixedly sleeved on both the stirring shaft and the right end of the rotating shaft.

A door is provided on the front side of the filter box 1.

[0027] Specifically, the stirring mechanism includes a stirring shaft 203 and a stirring rod 204. The stirring shaft 203 is fixedly installed on the output shaft of the motor 202. The bottom end of the stirring shaft 203 extends into the discharge pipe 4. The stirring rod 204 is provided on the stirring shaft 203 and is located in the storage tank 2. A gear mechanism is provided between the stirring shaft 203 and the rotating shaft 5.

[0028] Specifically, a unclogging rod 401 is provided on the stirring shaft 203, and the unclogging rod 401 is located inside the feed pipe 4.

[0029] Specifically, the gear mechanism includes two bevel gears 501. Both the stirring shaft 203 and the right end of the rotating shaft 5 are fixedly fitted with bevel gears 501. The bevel gears 501 are located above the partition plate 201, and the two bevel gears 501 mesh with each other.

[0030] Specifically, the reciprocating mechanism includes a reciprocating lead screw 301 and a lead screw seat 302. The same reciprocating lead screw 301 is rotatably installed on the inner walls of both sides of the functional box 3. The reciprocating lead screw 301 is located below the rotating shaft 5. The lead screw seat 302 is threaded onto the reciprocating lead screw 301. A slide rod 303 is fixedly installed on the top right side of the lead screw seat 302. The right end of the slide rod 303 extends into the filter box 1. The slide rod 303 is located above the filter plate 102.

The rotating shaft 5 then drives the reciprocating screw 301 to rotate through the transmission mechanism composed of transmission wheel 502 and transmission belt 503. As the reciprocating screw 301 rotates, the screw seat 302 can make linear reciprocating motion along the axial direction, thereby driving the slide bar 303 and the right end gear seat 304 and combing teeth 305 to make periodic reciprocating motion above the filter plate 102. When the melt enters the filter box 1 through the feed pipe 4 and passes through the filter plate 102, the reciprocating motion of the combing teeth 305 can dynamically comb the surface of the filter plate 102, which can realize the purpose of timely combing and intercepting impurities on the surface of the filter holes, preventing impurities from accumulating and forming filter cake, thus increasing the filtration resistance. The filtered clean melt can be discharged from the device through the discharge pipe 7. When maintenance is required, the filter plate 102 can be quickly replaced by opening the door on the front side of the filter box 1.
