[0002] Nylon FDY is a type of fully drawn yarn that is widely used in the textile industry. FDY is an abbreviation for Fully Drawn Yarn. Nylon FDY refers to chemical fiber filaments made from nylon raw materials through a specific one-step spinning and drawing process.

[0003] In the existing technology, nylon FDY component filtration devices are mainly used to filter molten nylon polymer during the nylon FDY production process. Since nylon polymer needs to maintain a certain temperature in the molten state to ensure its fluidity and spinnability, the filtration device is usually equipped with a heating device, such as electric heating wire or heat transfer oil heating, to keep the melt at a stable temperature during the filtration process. However, when the filter component needs to be replaced, its surface temperature may be high, and the operator needs to wait for it to cool down naturally before replacement, which reduces the efficiency of use.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Filter structure 3 includes a top cover 301. Two sliding plates 313 are fixedly installed through and on the top of the top cover 301. A top plate 305 is fixedly installed on the top of the two sliding plates 313. A limiting groove 306 is formed inside the top plate 305. First springs 307 are fixedly installed on both sides inside the limiting groove 306. A movable plate 308 is fixedly installed at one end of each first spring 307.

A push plate 311 is fixedly installed at one end of each second spring 310. A [missing information - likely a device or component] is fixedly installed on the top of the push plate 311. A pressure plate 312 is provided, with its top end penetrating the top plate 305. A slide plate 320 is fixedly installed at the bottom of the slide plate 313. An operating groove 317 is provided on the side of the slide plate 320 opposite to the slide plate 313. A limit plate 318 is provided inside the operating groove 317. The top of the limit plate 318 is fixedly connected to the moving plate 308. A locking block 319 is fixedly installed on the outer wall of the limit plate 318.

Two connecting rings 315 are fixedly installed on the outer wall of the filter screen 314. A locking groove 316 is provided on the inner wall of the connecting rings 315.

[0026] The effect achieved by the entire embodiment 1 is as follows: when the filter screen 314 needs to be replaced, the operator removes the top cover 301, the filter screen 314 leaves the housing 1, and then the operator presses down the pressure plate 312, the push plate 311 descends, the two inclined surfaces of the push plate 311 contact the two moving plates 308 respectively, pushing the two moving plates 308 to move, and then the limiting plate 318 drives the locking block 319 to leave the slot 316. At this time, the filter screen 314 can be completely removed. The new filter screen 314 is placed between the two sliding plates 313, the insert plate 320 enters the connecting ring 315, the inclined surface of the locking block 319 contacts the inner wall of the connecting ring 315, the first spring 307 is compressed, and when the locking block 319 moves to the side of the slot 316, the elastic force of the first spring 307 pushes the locking block 319 into the slot 316, thus completing the installation, which is convenient for installation and removal and prevents burns.

[0027] Example 2, as Figures 1-5 As shown, further, two connecting structures 4 are provided on the outside of the housing 1. The connecting structure 4 includes a lifting plate 401. The outer wall of the lifting plate 401 is fixedly connected to the top cover 301. A control plate 410 is provided at the bottom of the lifting plate 401. The outer wall of the control plate 410 is fixedly connected to the housing 1.

[0028] Furthermore, a connecting plate 402 is fixedly installed at the bottom of the lifting plate 401, and a fixing groove 403 is provided on the outer wall of the connecting plate 402.

[0029] Furthermore, the top of the control plate 410 is provided with a connecting groove 404, the inner wall of the connecting groove 404 is provided with a control groove 405, the inner wall of the control groove 405 is provided with a threaded hole 406, a threaded rod 407 is threadedly connected inside the threaded hole 406, a handle 409 is fixedly installed at one end of the threaded rod 407, and a fixing block 408 is movably connected to the other end of the threaded rod 407 away from the handle 409.

[0030] Furthermore, a sealing ring 304 is fixedly installed at the bottom of the top cover 301, and a sealing groove 7 is provided on the top of the housing 1 to improve the sealing performance.

[0031] Furthermore, a discharge pipe 8 is installed through and fixedly mounted on the bottom surface of the housing 1, and a first solenoid valve 9 is provided at the bottom of the discharge pipe 8. A feed pipe 302 is installed through and fixedly mounted on the top of the top cover 301, and a second solenoid valve 303 is provided at the top of the feed pipe 302.

[0032] Furthermore, an electric heating plate 5 is provided on the outer wall of the shell 1, and three evenly distributed support frames 2 are fixedly installed at the bottom of the shell 1.

[0033] The effect achieved by the entire embodiment 2 is that when installing the top cover 301, the worker inserts the two connecting plates 402 into the two connecting slots 404 respectively, and then the worker rotates the two handles 409. The handles 409 drive the threaded rod 407 to rotate, so that the threaded rod 407 moves along the threaded hole 406, thereby driving the fixing block 408 into the fixing slot 403. In this way, the installation can be completed, and the sealing ring 304 enters the sealing slot 7, which improves the installation efficiency and sealing performance.

[0034] Working principle: When in use, the operator pours the nylon polymer into the housing 1 through the feed pipe 302. The electric heating plate 5 starts to heat the nylon polymer, so that the melt maintains a stable temperature during the filtration process. The filter screen 314 intercepts impurities, gels, incompletely polymerized particles and other substances in the melt, and the melt leaves through the discharge pipe 8. When the filter screen 314 needs to be replaced, the operator removes the top cover 301, and the filter screen 314 leaves the housing 1. Then, the operator presses down the pressure plate 312, and the push plate 311 descends. The two inclined surfaces of the push plate 311 contact the two moving plates 308 respectively, pushing the two moving plates 308 to move. Then, through the limiting plate 318, the locking block 319 is driven to leave the slot 316. At this time, the filter screen 314 can be removed. The new filter screen 314 is placed between the two sliding plates 313, and the insert plate 320 enters the connecting ring 315. The inclined surface of the locking block 319 contacts the inner wall of the connecting ring 315, and the first spring 307 is compressed. When the locking block 319 moves to the side of the slot 316, the elastic force of the first spring 307 pushes the locking block 319 into the slot 316. This completes the installation, which is convenient for installation and removal and prevents burns. When installing the top cover 301, the worker inserts the two connecting plates 402 into the two connecting slots 404 respectively. Then, the worker rotates the two handles 409, which drives the threaded rod 407 to rotate, causing the threaded rod 407 to move along the threaded hole 406, thereby driving the fixing block 408 into the fixing slot 403. This completes the installation, and the sealing ring 304 enters the sealing slot 7, improving installation efficiency and sealing performance.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
