Description

Technical Field

[0001] This utility model relates to the field of cooling roller cleaning technology, and in particular to a self-cleaning device for condensation on the surface of a cooling roller. Background Technology

[0002] Cooling rollers are mainly used to cool and lower the temperature of various processed materials, such as thin metal sheets, plastic films, and paper. During the production process, such as after rolling or coating, the materials are often at a high temperature. The cooling roller absorbs the heat of the material through internal cooling medium circulation, such as water cooling or oil cooling, and cools it rapidly to a suitable temperature. This achieves the purpose of stabilizing material properties, improving the internal structure of the material, facilitating further processing or winding, and ensuring that the quality of the produced products meets the requirements.

[0003] There are several problems to be solved in existing condensation cleaning devices for cooling roller surfaces. On the one hand, poor scraper adhesion is a prominent issue. During the cleaning process, the scraper cannot be flexibly adjusted according to the actual conditions of the cooling roller surface, such as uneven condensation thickness or minor surface protrusions. This results in the scraper not always being in close contact with the cooling roller surface, which not only affects the scraping effect of condensation removal but may also leave condensation residue in some areas, making thorough cleaning impossible.

[0004] Therefore, in view of the problems of poor scraper adhesion and non-recycling of water resources in existing cooling roller surface condensation cleaning devices, there is a need for a cooling roller surface condensation cleaning device that can solve the above problems. Utility Model Content

[0005] In order to solve the problem of self-cleaning devices for condensation on the surface of cooling rollers in the prior art, this application provides a solution that solves the problems of poor scraper adhesion, inability to utilize water resources, and waste of water resources in the existing cooling roller surface condensation cleaning devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A self-cleaning device for condensation on the surface of a cooling roller includes a base plate. Support columns are fixedly connected to the four corners of the top of the base plate. A worktable is fixedly connected to the top of each support column. Mounting plates are fixedly connected to the left and right sides of the top of the worktable. Sleeves are connected to the mounting plates via lifting components. Sliding rods are slidably connected to the inner walls of each sleeve. Springs are provided on the inner walls of each sleeve. A scraper is fixedly connected to the front end of each sliding rod. A drainage groove is formed on the inner wall of the scraper. The scraper and its front inner wall are inclined. A connecting pipe is fixedly connected to the right outer wall of the scraper.

[0008] As a further improvement of this utility model, the rear ends of the springs are all connected to the inner wall of the sleeve, and the front ends of the springs are all connected to the rear outer wall of the slide rod.

[0009] As a further improvement of this utility model, the lifting assembly includes a motor fixedly connected to the top of the left mounting plate, the drive end of the motor is fixedly connected to a threaded rod, and the bottom end of the threaded rod is rotatably connected to the inner wall of the mounting plate.

[0010] As a further improvement of this utility model, the lifting assembly also includes a fixing rod fixedly connected to the inner wall of the right mounting plate, and both the fixing rod and the threaded rod are provided with sliding blocks on their outer walls.

[0011] As a further improvement of this utility model, the inner wall of the sliding block on the left is threadedly connected to the outer wall of the threaded rod, the inner wall of the sliding block on the right is slidably connected to the outer wall of the fixed rod, and the rear end of the sleeve is fixedly connected to the inner wall of the sliding block.

[0012] As a further improvement of this utility model, a collection box is fixedly connected to the top of the base plate, a cover is fixedly connected to the top of the collection box, and the bottom end of the connecting pipe passes through the inner wall of the right side of the collection box and is fixedly connected to the inner wall of the collection box.

[0013] As a further improvement of this utility model, a filter plate is fixedly connected to the top of the inner wall of the collection box, an activated carbon filter layer is fixedly connected to the bottom of the inner wall of the collection box, and a drain pipe for connecting an external condenser pipe is fixedly connected to the left inner wall of the collection box.

[0014] As a further improvement of this utility model, the top left and right sides of the workbench are fixedly connected to fixing blocks, and the inner wall of the opposite side of the fixing blocks is equipped with a main cooling roller.

[0015] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0016] 1. In this utility model, the sliding fit between the sleeve and the slide bar and the buffering and restoring effect of the spring enable the scraper to flexibly adapt to the state of the roller surface and maintain a close fit, ensuring a stable cleaning effect; the design of the inclined surface and the drainage groove optimizes the condensate collection and discharge process, improves liquid treatment efficiency, and ensures the continuous and efficient operation of the device.

[0017] 2. In this utility model, the liquid flowing into the collection box can be initially filtered by the filter plate, and the activated carbon filter layer further improves the quality of the liquid.

[0031] Example 1: Refer to Figure 1 - Figure 3 A self-cleaning device for condensation on the surface of a cooling roller includes a base plate 1. Support columns 2 are fixedly connected to the four corners of the top of the base plate 1. A worktable 3 is fixedly connected to the top of each support column 2. Mounting plates 6 are fixedly connected to the left and right sides of the top of the worktable 3. Sleeves 11 are connected to the mounting plates 6 via lifting components. Slide rods 12 are slidably connected to the inner walls of the sleeves 11. Springs 13 are provided on the inner walls of the sleeves 11. A scraper 14 is fixedly connected to the front end of each slide rod 12. A connecting pipe 15 is fixedly connected to the right outer wall of the scraper 14. The rear ends of each spring 13 are connected to the inner wall of the sleeve 11, and the front ends of each spring 13 are connected to the rear outer wall of the slide rod 12. (Refer to...) Figure 4 The inner wall of the scraper 14 is provided with a drainage groove 22, and the scraper 14 and the front inner wall are set as inclined surfaces 21.

[0032] The lifting assembly includes a motor 7 fixedly connected to the top of the left mounting plate 6. A threaded rod 8 is fixedly connected to the drive end of the motor 7. The bottom end of the threaded rod 8 is rotatably connected to the inner wall of the mounting plate 6. The lifting assembly also includes a fixed rod 9 fixedly connected to the inner wall of the right mounting plate 6. Sliding blocks 10 are provided on the outer walls of both the fixed rod 9 and the threaded rod 8. The inner wall of the left sliding block 10 is threadedly connected to the outer wall of the threaded rod 8, and the inner wall of the right sliding block 10 is slidably connected to the outer wall of the fixed rod 9. The rear ends of the sleeve 11 are fixedly connected to the inner walls of the sliding blocks 10.

[0033] The top left and right sides of the workbench 3 are fixedly connected to the fixing blocks 4, and the main cooling rollers 5 are installed on the inner wall of the opposite side of the fixing blocks 4.

[0034] Specifically, the base plate 1 serves as the bottom support for the entire device, and the support column 2 firmly supports the workbench 3, providing a stable bearing platform for the various components subsequently installed on the workbench 3, ensuring the stability of the entire device structure. The workbench 3 provides an installation surface for the mounting plate 6, ensuring that the lifting assembly can reliably drive the scraper 14 and other components to move up and down during operation, realizing the cleaning operation on the surface of the main cooling roller 5. The mounting plate 6 serves as the mounting carrier for the various components of the lifting assembly. After the motor 7 is started, it can drive the threaded rod 8 to rotate. Through the threaded connection, the left sliding block 10 moves up and down along the threaded rod 8, while the right sliding block 10 slides up and down synchronously along the fixed rod 9, thereby realizing that the entire lifting assembly drives the sleeve 11 and other subsequent components to move up and down, thereby adjusting the vertical position of the scraper 14 on the surface of the main cooling roller 5 to meet the cleaning needs at different heights. At the same time, when it is not necessary to clean the main cooling roller 5, the motor 7 is started to raise the position of the scraper 14.

[0035] The sleeve 11 provides a guide channel for the slide bar 12, allowing the slide bar 12 to slide smoothly back and forth along the inner wall of the sleeve 11. This ensures that the scraper 14 connected to the front end of the slide bar 12 can flexibly adjust its position within a certain range when it contacts the surface of the main cooling roller 5, adapting to the actual conditions of the surface of the main cooling roller 5 and the force changes during the scraping process of condensation. The spring 13 plays a buffering and resetting role between the sleeve 11 and the slide bar 12. When the scraper 14 encounters different resistances while scraping condensation off the surface of the main cooling roller 5, such as uneven condensation thickness or small protrusions on the surface of the main cooling roller 5, the spring 13 can buffer the external force through extension and contraction, preventing damage to components such as the scraper 14 due to excessive force. Simultaneously, after the force is applied, it can push the slide bar 12 to reset, ensuring that the scraper 14 always maintains good contact with the surface of the main cooling roller 5, facilitating continuous and effective cleaning. The inclined surface 21 helps guide the condensate scraped off the surface of the main cooling roller 5 towards the drainage trough 22, accelerating the collection and discharge of liquid and optimizing the scraper 14's collection of condensate. The collection and discharge functions make the liquid handling during the entire cleaning process more reasonable and efficient, ensuring that the cleaning device can work continuously and stably. The drainage groove 22 inside the scraper 14 plays the role of collecting and gathering condensed water, so that the condensed water scraped off by the scraper 14 can first be concentrated in the drainage groove 22, and then discharged more smoothly through the connecting pipe 15, improving the efficiency and orderliness of drainage, and ensuring the continuity of liquid handling during the cleaning process. The setting of the sleeve 11, spring 13, inclined surface 21 and drainage groove 22 facilitates the flexible adjustment of the scraper 14 position, buffers external force, fits the roller surface, and drains water efficiently, ensuring the continuous and stable operation of the cleaning device.

[0036] The fixing block 4 limits and supports the main cooling roller 5 from both sides, so that the main cooling roller 5 can be stably positioned above the worktable 3, preventing axial or radial displacement during operation or cleaning, ensuring that the scraper 14 can perform stable and orderly cleaning work along the surface of the main cooling roller 5, and guaranteeing the cleaning effect and normal performance of the main cooling roller 5.

[0037] Example 2: Refer to Figure 1 , Figure 2 and Figure 5 A collection box 16 is fixedly connected to the top of the base plate 1, and a cover 17 is fixedly connected to the top of the collection box 16. The bottom end of the connecting pipe 15 passes through the inner wall of the right side of the collection box 16 and is fixedly connected to the inner wall of the collection box 16. A filter plate 18 is fixedly connected to the top of the inner wall of the collection box 16, and an activated carbon filter layer 19 is fixedly connected to the bottom of the inner wall of the collection box 16. A drain pipe 20 for connecting to an external condenser pipe is fixedly connected to the inner wall of the left side of the collection box 16.

[0038] Specifically, the base plate 1 provides a stable foundation for the collection box 16, ensuring that the collection box 16 is stably positioned in the appropriate location within the entire device. This facilitates the subsequent collection and treatment of liquids and other substances discharged from the connecting pipe 15. The cover 17 seals the collection box 16, preventing external impurities from entering the collection box 16 and facilitating subsequent liquid treatment operations. The connecting pipe 15 serves as a transport channel for the liquid discharged from the scraper 14, transporting the condensate and other liquids scraped down and collected by the scraper 14 to the collection box 16, thus transferring the liquid from the cleaning area to the collection area and facilitating subsequent unified liquid treatment.

[0039] The filter plate 18 can perform preliminary filtration on the liquid flowing into the collection tank 16 from the connecting pipe 15, intercepting larger particulate impurities that may be carried in the liquid, preventing these impurities from continuing to deposit in the collection tank 16 or flowing out with the subsequently discharged liquid, ensuring that the liquid in the collection tank 16 is relatively pure and that the subsequent processing steps can proceed normally. The activated carbon filter layer 19 can further adsorb and treat the filtered liquid flowing into the collection tank 16, improving the quality of the liquid and making the liquid discharged from the collection tank 16 cleaner, reducing adverse effects on the external environment. The drain pipe 20 serves as the channel for the discharged liquid after treatment in the collection tank 16, transporting the filtered liquid to the external condenser pipe, and then back to the main cooling roller 5 for water recycling, reducing water waste.

[0040] Working principle: The base plate 1 supports the worktable 3 via the support column 2. The main cooling roller 5 is installed on the fixed block 4 on the worktable 3. When the main cooling roller 5 is working, condensation occurs on its surface. When cleaning is required, the motor 7 at the top of the left mounting plate 6 starts, driving the threaded rod 8 to rotate. The left sliding block 10 moves up and down along the threaded rod 8, and the right sliding block 10 slides synchronously along the fixed rod 9, causing the sleeve 11 to descend. This causes the scraper 14 at the front end of the slide rod 12 to contact the surface of the main cooling roller 5. The scraper 14 moves axially along the main cooling roller 5 with the sleeve 11, and the slide rod 12 slides inside the sleeve 11. The spring 13 gently pushes down the slide rod 12. The scraper 14 is subjected to force and made to adhere to the roller surface. The inclined surface 21 guides the condensed water into the drainage trough 22, and then into the collection box 16 through the connecting pipe 15. The filter plate 18 in the collection box 16 filters liquid impurities, and the activated carbon filter layer 19 adsorbs odors and residual impurities. The treated liquid is connected to the external condenser pipe through the left drain pipe 20 and is transported back to the main cooling roller 5 for recycling. When cleaning is not required, the motor 7 rotates in the reverse direction to drive the sleeve 11 to rise, so that the scraper 14 is removed from the surface of the main cooling roller 5. The cover 17 keeps the collection box 16 sealed, and the entire device maintains a stable operating state.
