Description

Technical Field

[0001] This utility model relates to the field of lubrication technology for texturing machines, and in particular to an oil circulation and filtration device for texturing machines. Background Technology

[0002] Lubricants are used in texturing machines to improve fiber processing performance and enhance product quality during operation, while reducing friction and wear on the equipment to ensure smooth operation. However, during use, additives in the lubricant may react chemically with the base oil components, producing acidic substances or non-oil-soluble deposits, altering the original properties of the lubricant and leading to decreased lubrication efficiency. With prolonged use, impurities produced by the decomposition of additives may accelerate oil oxidation, shortening the lubricant's lifespan.

[0003] In existing texturing machines, the lubricant after conditioning contains unfiltered protective layer debris or oxidation products that directly enter the lubrication system, exacerbating equipment wear. At the same time, the lubricant is prone to absorbing moisture after contact with air, and the moisture causes the additives to hydrolyze, producing precipitates and reducing transparency. Frequent addition of chemical additives is required to maintain performance, significantly increasing operating costs. Utility Model Content

[0023] Please see Figures 1-2 In this embodiment, the anti-reverse mechanism 2 includes an oil inlet pipe 201; an overflow hole 202 is circumferentially opened at the end of the oil inlet pipe 201, and a number of retention hooks 203 are arranged around the inner wall of the oil inlet pipe 201. A number of hook holes 205 for accommodating the retention hooks 203 are opened on the side wall of the inner pipe 204. The oil inlet pipe 201 and the inner pipe 204 are connected by the retention hooks 203. A pull rod 206 is fixedly connected to the top end of the inner pipe 204. A float 207 is hinged to the top end of the pull rod 206. A float ball 208 is passed through the end of the float 207. The end of the float 207 that is hinged to the pull rod 206 is curved and crank-shaped, providing a large axial force.

[0024] Please see Figures 3-4In this embodiment, the extraction mechanism 3 includes a first drive motor 301, a pump head 302, and a mesh tap 303; the bottom of the oil tank 1 is provided with a mesh tap 303, which is connected to the pump head 302 through a pipe, and the input shaft of the pump head 302 and the output shaft of the first drive motor 301 are coaxially rigidly connected.

[0025] The three-stage filtration mechanism 4 includes a primary filter cartridge 401, a secondary filter cartridge 402, and a tertiary filter cartridge 403 connected in series. Each filter cartridge contains a composite filter rod 404 with filtration accuracies of 10µm, 5µm, and 1µm, respectively. The bottom of the composite filter rod 404 is connected to an outflow layer 405, and the top of the composite filter rod 404 is equipped with a quick-release cap 406. A handle 407 is integrated on the cap 406 of the composite filter rod 404.

[0026] Please see Figures 1-5 In this embodiment, the coalescing separation mechanism 5 includes a centrifuge body 501; an oil inlet 502 is provided on the upper part of the centrifuge body 501; a coalescing filter 503 is provided in the middle of the centrifuge body 501, a separation filter 504 is sleeved on the outside of the coalescing filter 503, a drain valve 505 is connected to the bottom of the coalescing filter 503, an oil outlet 506 is provided on the outside of the separation filter 504, and a centrifugal shaft 507 is fixedly connected to the top of the coalescing filter 503; a belt 509 is sleeved on the outside of the output shaft of the second drive motor 508 and the centrifugal shaft 507, and the output shaft of the second drive motor 508 drives the belt 509 to rotate, thereby causing the centrifugal shaft 507 to rotate; an oil outlet pipe with a solenoid valve 601 is provided in the middle of the oil storage tank 6, a liquid level sensor 602 is provided in the oil storage tank 6, and a waste discharge pipe 101 is provided at the bottom of the oil inlet tank 1.

[0027] When in operation, this device is connected to the lubrication system of the texturing machine. When oil is introduced, the oil flows out through the hook hole 205 of the inner tube 204, passes through the overflow hole 202 of the oil inlet pipe 201, and flows into the oil tank 1. The first drive motor 301 drives the pump head 302 to draw the oil in the oil tank 1 into the pipeline through the mesh tap 303, while filtering out larger solid impurities. The oil passes through the three-stage filtration mechanism 4 in sequence. The composite filter element rod 404 is made of ceramic carbon rod material to adsorb debris and oxidation products. The three-stage gradient achieves the gradient interception from 10μm to 5μm and then to 1μm. The treated oil enters the oil inlet chamber 502 through the pipeline. Under the high-speed rotation of the centrifuge body 501, the coalescing filter 503 coalesces tiny water droplets under the centrifugal force field. The coalescing filter 503 can be made of high-density gradient glass fiber filter element. The separation filter 504 introduces the water phase into the drain valve 505, and the oil phase enters the oil storage tank 6 through the oil outlet 506.

[0028] It is also considered that when the oil level in the oil tank 1 is too high, the float 208 floats with the liquid level and drives the inner tube 204 to rise and fall through the pull rod 206, blocking the oil from entering the oil tank 1; when the oil is immersed in the oil tank 6, the solenoid valve 601 is opened to discharge the oil; large impurities at the bottom of the oil tank 1 are discharged through the waste discharge pipe 101.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.
