Description

Technical Field

[0001] This utility model relates to the field of cooling water recovery technology, specifically a cooling water recovery device for the production of polyethylene sheathed cables. Background Technology

[0002] Cooling water used in the production of polyethylene sheathed cables is a liquid used to cool the polyethylene sheath during the cable manufacturing process. It typically employs a circulating water system, possessing excellent cooling performance, rapidly removing heat from the cable surface, allowing the polyethylene sheath to quickly solidify and set, ensuring its appearance quality and performance. Simultaneously, the cooling water also acts as a cleaner, preventing impurities from adhering to the cable surface. Furthermore, by adding additives such as corrosion inhibitors, the cooling equipment can be protected, extending its service life.

[0003] A cooling water recovery device, authorized by announcement number CN214914156U, includes a filter sedimentation tank, a fixed frame, and support legs. The fixed frame is fixedly connected to the upper inner side of the filter sedimentation tank. A filter frame is slidably connected to the upper end of the fixed frame, and a filter screen is fixedly connected to the inner side of the filter frame. A first motor is fixedly connected to the lower end of the filter sedimentation tank. A threaded shaft is fixedly connected to the upper end of the output shaft of the first motor. A lifting sleeve is spirally connected to the outer side of the threaded shaft, and a sedimentation plate is fixedly connected to the upper end of the lifting sleeve. In this invention, the filter screen, threaded shaft, and sedimentation plate effectively filter small impurities such as debris in the cooling water. The sedimentation plate allows fine dust and other impurities to settle. Simultaneously, the rotation of the threaded shaft allows the settled cooling water to flow out slowly, thus achieving effective filtration of the cooling water.

[0004] As shown in the above equipment, although the existing cooling water recovery device for polyethylene sheathed cable production uses a filter screen to filter out small impurities such as debris in the cooling water and uses a sedimentation plate to settle out tiny dust particles and other impurities, as the cooling water is continuously filtered, impurities gradually accumulate on the filter screen, causing the filter screen to become clogged, which slows down the filtration speed of the cooling water and reduces the recovery efficiency.

[0032] The filtrate cleaning mechanism 6 includes a filtrate chamber 61, which is located inside the recovery and processing tank 1. A discharge box 62 is fixedly installed on the outer wall of the filtrate chamber 61.

A cleaning assembly 66 is provided on the outer wall of the filtrate chamber 61, and a limit groove 67 is provided on the outer wall of the filtrate chamber 61.

[0033] The cleaning assembly 66 includes a fixed base 661, which is fixedly installed on the outer wall of the filtrate chamber 61. A threaded rod 662 is rotatably connected to the outer wall of the fixed base 661. A drive motor 663 is fixedly installed on the outer wall of the fixed base 661.

Subsequently, the cool air is delivered into the cooling tank 8 via the air supply pipe 92 and heat dissipation plate 96 to neutralize the hot air, accelerating the cooling of the cooling water. After cooling, the cooling water is transported to the recycling tank 1 via the infusion pipe 4. During transport, the flow rate of the cooling water can be adjusted via the throttle valve 5. After entering the recycling tank 1, the cooling water falls by gravity and is cooled by the sieve plates A65 and B69. Impurities in the water are screened, and then the cooling water through the screen plate is transported to the recovery box 12 for collection via the drop plate 11 and the through pipe 14. The screened impurities, after being screened by the cooling water, are driven by the drive motor 663 to rotate the threaded rod 662 at its output end. With the help of the limiting groove plate 664, the sliding groove 666 and the limiting sliding groove 67, the two-layer cleaning plate 665 connected to the threaded wall of the threaded rod 662 moves, sweeping the impurities on the outer walls of the screen plate A65 and the screen plate B69 into the discharge box 62. Then, the impurities are transported to the conveying box 68 by the falling and conveying pipe 610, and then transported to the waste box 13 for collection via the through pipe 14 below the conveying box 68.
