Description

Technical Field

[0001] This utility model belongs to the field of cooling equipment technology, specifically a device for cleaning sediments from a circulating cooling water cooling rack. Background Technology

[0002] Circulating cooling water cooling racks are commonly used heat dissipation devices in industrial production. They achieve heat exchange by circulating cooling water in cooling pipes, ensuring the stable operation of subsequent production equipment. During long-term use, calcium and magnesium ions, microorganisms and impurities in the circulating cooling water are prone to deposit on the inner wall of the cooling pipes, forming deposits such as scale and biological slime.

[0003] In practical use, most existing cooling water rack sediment cleaning devices are designed with a fixed height, and the horizontal height of the cleaning components cannot be adjusted. Fixed-height cleaning devices can only be used for cooling pipes of a single height. When dealing with cooling water racks of different heights, different sizes of cleaning devices need to be replaced, resulting in limited cleaning range, poor versatility, and increased equipment investment costs and maintenance difficulties for enterprises.

[0004] To address this issue, we propose a device for cleaning sediment from a circulating cooling water cooling rack. Utility Model Content

[0005] The purpose of this invention is to provide a device for cleaning sediment from a circulating cooling water rack, in order to solve the technical problem that in the prior art, most cleaning devices are designed at a fixed height and the vertical position of the cleaning components cannot be adjusted.

[0006] To solve the above technical problems, the technical solution of this utility model is as follows: a circulating cooling water cooling rack sediment cleaning device, including a support frame and a cooling water frame. Two auxiliary blocks are fixedly connected to both sides of the support frame. Each auxiliary block has a connecting block slidably disposed therein and a vertically disposed threaded rod rotatably connected thereto. The threaded rod is threadedly connected inside the connecting block. A servo motor is fixedly connected to the upper surface of the auxiliary block. The output end of the servo motor is fixedly connected to the upper end of the threaded rod. The two sides of the cooling water frame are respectively fixedly connected to the sides of the two connecting blocks. A support plate is fixedly connected inside the cooling water frame. Two cooling pipes are disposed on the upper surface of the support plate. A horizontal plate is fixedly connected to the inner side of the support frame. Two electric push rods are fixedly connected to the side of the horizontal plate near the cooling pipes. A cleaning brush head is fixedly connected to the telescopic end of each electric push rod. An elastic rubber is fixedly connected to the outer surface of each cleaning brush head.

[0007] Furthermore, each of the auxiliary blocks has a reinforcing groove inside, and a reinforcing bolt is slidably connected inside each of the reinforcing grooves. Each of the reinforcing bolts is threadedly connected to one side of the connecting block.

[0008] Furthermore, each of the threaded rods has an auxiliary bearing fitted on its outer surface, and each of the auxiliary bearings is embedded inside the auxiliary block.

[0009] Furthermore, two sturdy blocks are fixedly connected to the outer surface of each cooling pipe, and the bottom surface of each sturdy block is fixedly connected to the upper surface of the support plate.

[0010] Furthermore, a water outlet pipe is provided on the left side of the cooling pipe, and a water inlet pipe is provided on the right side of the cooling pipe.

[0011] Furthermore, both the outlet pipe and the inlet pipe are fixedly connected to a regulating valve, both ends of each cooling pipe are fixedly connected to a first flange, and the outer surfaces of both the outlet pipe and the inlet pipe are fixedly connected to three second flanges. The outer surface of each first flange is provided with multiple locking bolts, and the ends of each group of locking bolts that are close to each other pass through the second flange and are threadedly connected to the first flange.

[0012] This utility model has the following advantages compared with the prior art:

[0013] 1. This utility model, by setting a servo motor to drive a threaded rod, drives the connecting block and cooling water frame to lift and lower as a whole, realizing flexible adjustment of the working height of the cooling pipe. This allows the cleaning device to be adapted to cooling water frames of different heights, improving the equipment's versatility and reducing the cost of equipping multiple sets of specialized equipment for different specifications. An electric push rod drives a cleaning brush head with elastic rubber to perform reciprocating cleaning of the inner wall of the cooling pipe. This design replaces the traditional, inefficient, and heavy manual cleaning method, not only providing high cleaning efficiency and uniform results but also reducing the skill requirements and labor intensity of operators. The elastic rubber material covering the cleaning brush head effectively scrapes away deposits while avoiding scratches to the inner wall of the cooling pipe caused by rigid scraping due to its flexibility, thus extending the service life of the cooling pipe while ensuring cleaning effectiveness.

[0014] 2. This utility model provides stable radial support for the threaded rod by setting an auxiliary bearing, ensuring smooth transmission; through the cooperation of the reinforcing bolt and the reinforcing groove, the connecting block can be locked after the height is adjusted to the correct position, effectively preventing accidental displacement of the equipment during operation or cleaning, and ensuring the stability and accuracy of the cleaning operation.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figures 1 to 5 The device shown is a sediment cleaning device for a circulating cooling water rack, comprising a support frame 1 and a cooling water frame 6. Two auxiliary blocks 2 are fixedly connected to both sides of the support frame 1. Each auxiliary block 2 is a hollow cubic block. A connecting block 5 is slidably disposed within each auxiliary block 2, and a vertically arranged threaded rod 3 is rotatably connected to it. The threaded rod 3 is threaded into the connecting block 5. A servo motor 4 is fixedly connected to the upper surface of the auxiliary block 2. The two servo motors 4 are configured in a master-slave mode for synchronous control. The output end of the servo motor 4 is fixedly connected to the upper end of the threaded rod 3. The cooling water frame 6 is fixedly connected to the sides of the two connecting blocks 5 respectively. A support plate 8 is fixedly connected inside the cooling water frame 6. Two cooling pipes 9 are disposed on the upper surface of the support plate 8. The inner side of the support frame 1 is fixedly connected to... There is a horizontal plate 18, and two electric push rods 19 are fixedly connected to the side of the horizontal plate 18 near the cooling pipe 9. Each electric push rod 19 has a cleaning brush head 20 fixedly connected to its telescopic end. Each cleaning brush head 20 has an elastic rubber 21 fixedly connected to its outer surface. The horizontal plate 18 provides a stable mounting carrier for the electric push rods 19 to prevent them from shifting. The electric push rods 19 move laterally through the telescopic belt and cleaning brush head 20 to clean the deposits on the cooling pipe 9. The elastic rubber 21 is flexible, fits the pipe wall to prevent scratches, increases the friction between the brush head and the deposits, improves the cleaning effect, and reduces dead corners.

[0023] To assist in limiting and fixing the horizontal position of the connecting block 5, each auxiliary block 2 has a reinforcing groove 7 inside. The width of the reinforcing groove 7 is adapted to the size of the reinforcing bolt 22. Each reinforcing groove 7 is slidably connected with a reinforcing bolt 22. Each reinforcing bolt 22 is threadedly connected to one side of the connecting block 5. When the reinforcing bolt 22 is tightened, the bottom of the reinforcing bolt 22 gradually approaches and contacts the outside of the reinforcing groove 7. Through contact friction, the position of the connecting block 5 is fixed.

[0024] Each threaded rod 3 has an auxiliary bearing 11 fitted on its outer surface, and each auxiliary bearing 11 is embedded inside the auxiliary block 2. This provides radial support to the threaded rod 3 to prevent tilting and wobbling, ensuring stable rotation, while also reducing friction between the two, lowering the load on the servo motor 4, improving power efficiency, reducing wear, and extending component life.

[0025] Two sturdy blocks 12 are fixedly connected to the outer surface of each cooling pipe 9. The bottom surface of each sturdy block 12 is fixedly connected to the upper surface of the support plate 8. The two sturdy blocks 12 fix the cooling pipe 9 to the support plate 8 to prevent the cooling pipe 9 from falling off due to water flow or vibration, ensuring the heat dissipation posture and efficiency, and avoiding water leakage.

[0026] A water outlet pipe 13 is provided on the left side of the cooling pipe 9, and a water inlet pipe 14 is provided on the right side of the cooling pipe 9. The water inlet pipe 14 delivers hot water to be cooled, and the water outlet pipe 13 discharges cooled warm water. The two form a circulation channel to ensure that the cooling pipe 9 continuously dissipates heat and provides a guarantee for the stability of the production equipment.

[0027] Both the outlet pipe 13 and the inlet pipe 14 are internally connected to regulating valves 15, which control the cooling water flow to adapt to different heat dissipation requirements. Each cooling pipe 9 has a first flange 10 fixedly connected to both ends. Three second flanges 16 are fixedly connected to the outer surfaces of both the outlet pipe 13 and the inlet pipe 14. Each first flange 10 has multiple locking bolts 17 on its outer surface. The ends of each set of locking bolts 17 that are close to each other pass through a second flange 16 and are threadedly connected to a first flange 10. This flange connection ensures a tight seal while facilitating disassembly and assembly during maintenance and replacement, simplifying the maintenance process for the cooling pipes 9.

[0028] The specific working process of this utility model is as follows: In use, the servo motor 4 is started, driving the threaded rod 3 to rotate inside the auxiliary block 2. Since the connecting block 5 is threadedly connected to the threaded rod 3 and slidably connected inside the auxiliary block 2, the rotation of the threaded rod 3 drives the connecting block 5 to move vertically along the auxiliary block 2, thereby driving the cooling water frame 6 between the two connecting blocks 5 to move synchronously. When the cooling pipe 9 on the cooling water frame 6 reaches the target height, the servo motor 4 is stopped, and the reinforcing bolt 22 is slid along the reinforcing groove 7 and screwed into the connecting block 5 to lock the position of the connecting block 5, completing the height adjustment. Hot water to be cooled is supplied to the cooling pipe 9 through the water inlet pipe 14. The regulating valve 15 is rotated according to the heat dissipation requirements to control the flow rate of cooling water in the water inlet pipe 14. During the flow of hot water in the cooling pipe 9, heat is exchanged with the outside air. The water is cooled and discharged through the outlet pipe 13. The regulating valve 15 on the outlet pipe 13 can adjust the water flow rate to ensure stable circulation of water in the cooling pipe 9. When deposits appear on the inner wall of the cooling pipe 9, the locking bolts 17 on the first flange 10 and the second flange 16 are unscrewed to separate the cooling pipe 9 from the outlet pipe 13 and the inlet pipe 14. Then, the electric push rod 19 on the horizontal plate 18 is activated. The extension end of the electric push rod 19 drives the cleaning brush head 20 to move towards the cooling pipe 9. The elastic rubber 21 on the outer surface of the cleaning brush head 20 fits against the inner wall of the cooling pipe 9. As the electric push rod 19 continues to extend and retract, the cleaning brush head 20 slides laterally along the inner wall of the cooling pipe 9 to physically remove deposits such as scale and biological slime. After cleaning, the electric push rod 19 is controlled to retract, driving the cleaning brush head 20 to reset.
