DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] See also Figures 1 to 6 A cooling device for a rough rolling roller table includes a roll stand 1 and a recovery pipe 5. A roll body 2 is rotatably installed inside the roll stand 1. A spray device 4 is provided on the roll stand 1. A receiving pool 3 is provided directly below the roll body 2 of the roll stand 1. The roll stand 1 supports and allows the roll body 2 to rotate therein for guiding and processing rolled materials. The recovery pipe 5 is responsible for drawing back the used coolant from the receiving pool 3 for recycling. It is worth noting that there should be a corresponding pump body to provide power, which is not described here.

[0026] A accommodating cavity 12 is provided inside the receiving pool 3, and the spraying device 4 is located on the roller frame 1. The specific structure of the spraying device 4 is similar to that in CN222198305U and will not be repeated here. The spraying device 4 is used to spray coolant onto the surface of the rotating roller body 2 to reduce its temperature and prevent deformation or damage of the material caused by high temperature. The roller frame 1 is provided with a receiving pool 3 directly below the roller body 2. The receiving pool 3 is placed directly below the roller body 2 and is used to collect the coolant sprayed by the spraying device 4 and flowing through the roller body 2.

[0027] A sliding frame 13 is slidably installed inside the receiving pool 3, and a plug-in plate 14 is movably installed on the sliding frame 13. A filter plate 15 is inlaid and installed on the plug-in plate 14. The sliding frame 13 can slide inside the receiving pool 3 to facilitate adjustment of the position of the filter plate 15. The plug-in plate 14 is movably connected to the sliding frame 13, so that it can be removed from the sliding frame 13 to facilitate cleaning or replacement of the filter plate 15.

[0028] The receiving pool 3 is provided with a driving mechanism, which controls the movement of the sliding frame 13 so that the filter plate 15 can be moved to a position convenient for cleaning, thereby simplifying the cleaning process.

[0029] A connecting pipe 6 is embedded in the receiving pool 3, which is connected to the recovery pipe 5, and an electric control valve 10 is installed on the connecting pipe 6. The connecting pipe 6 guides the coolant in the receiving pool 3 to the recovery pipe 5, and the electric control valve 10 controls the process to ensure that the coolant flows only when needed.

[0030] It is worth noting that there should be a corresponding device for controlling the liquid level inside the receiving pool 3 so that the maximum liquid level of the coolant cannot be higher than the height of the filter plate 15, thereby preventing the coolant from being discharged directly without being filtered.

[0031] When in use, the sliding frame 13 and the filter plate 15 need to be placed on the side close to the connecting pipe 6, so that when the coolant is recovered, the filter plate 15 can intercept the iron filings in the fluid to prevent them from mixing into the coolant circulation system and causing unnecessary damage.

[0032] The length of the receiving pool 3 is greater than the length of the roller frame 1, and the side of the receiving pool 3 facing the drive motor 7 is smoothly exposed from the roller frame 1, leaving space for operation. The longer receiving pool 3 design provides a larger coolant collection area, and its excess part leaves enough space for the operator to carry out necessary cleaning and maintenance work.

[0033] The driving mechanism includes a driving motor 7 and a threaded rod 18. There are two threaded rods 18. A pulley 9 is installed between the two threaded rods 18 through a synchronous belt 8. Nut pairs 16 are threadedly installed on the two threaded rods 18. The nut pairs 16 are fixedly connected to the sliding frame 13. The driving motor 7 is installed on the receiving pool 3, and the shaft output end of the driving motor 7 is fixedly connected to one of the threaded rods 18.

[0034] Preferably, tooth transmission or chain transmission can be adopted between the pulley 9 and the synchronous belt 8 to ensure the stability of the operation of the synchronous belt 8.

[0035] When the drive motor 7 is started, it drives the corresponding threaded rod 18 to rotate, and the synchronous belt 8 and the pulley 9 are used to keep the two threaded rods 18 running synchronously, thereby pushing the nut pair 16 together with the sliding frame 13 to move linearly along the threaded rod 18, thereby adjusting the position of the filter plate 15, so that it moves to the side with operating space for easy cleaning and maintenance.

[0036] Scraping plates 17 are embedded and installed on the three surfaces of the sliding frame 13 that are in contact with the receiving pool 3. The scraping plates 17 are tightly against the receiving pool 3.

[0037] When the sliding frame 13 moves, it forms a plane to move the impurities in the drive, so that these impurities can be concentrated and moved to the side with the operating space. The operator can use shovels, electromagnets and other materials to perform quick cleaning activities, and the scraper plate 17 can remove the residues on the inner wall of the receiving pool 3 during the movement of the sliding frame 13 to ensure the cleanliness of the inside of the receiving pool 3.

[0038] An electric telescopic rod 11 is provided at the bottom of the receiving pool 3, and the other end of the electric telescopic rod 11 is fixedly mounted on the roller frame 1. The electric telescopic rod 11 can adjust the height position of the receiving pool 3 relative to the roller body 2, so that the bottom of the roller body 2 can directly contact the coolant inside the receiving pool 3. In conjunction with the rotating roller body 2, the effect of immersion cooling can be achieved, which can be carried out synchronously or asynchronously with the spray cooling to ensure the cooling effect and adapt to different operating requirements.

[0039] A handle 19 is fixedly mounted on the plug board 14 , and the handle 19 facilitates manual operation of the plug board 14 , making it easier to insert the plug board into or remove it from the sliding frame 13 , thereby improving the efficiency of maintenance work.

[0040] The working process of the present invention is as follows: the spraying device 4 sprays coolant onto the surface of the roller body 2 that needs to be cooled to reduce its temperature and prevent deformation or damage of the material caused by high temperature. The coolant flows through the roller body 2 under the action of gravity and then drips into the receiving pool 3.

[0041] The coolant after preliminary filtration is drawn into the recovery pipe 5 through the connecting pipe 6. The electric control valve 10 controls the flow of the coolant to ensure that the coolant flows only when needed, thereby realizing the recycling of the coolant. The pump body (not described in detail) provides power to support this process. During this process, the filter plate 15 can perform preliminary filtration of iron filings and other impurities in the coolant.

[0042] When cleaning is required, the drive motor 7 starts to drive the threaded rod 18 to rotate, and the synchronous belt 8 and the pulley 9 are used to keep the two threaded rods 18 running synchronously, thereby pushing the nut pair 16 together with the sliding frame 13 to move linearly along the threaded rod 18, so that the filter plate 15 can be moved to a position convenient for cleaning, simplifying the cleaning process, and the handle 19 on the plug-in plate 14 facilitates manual operation, so that the plug-in plate 14 can be easily inserted or pulled out from the sliding frame 13, making it easy to clean or replace the filter plate 15 and improving the efficiency of maintenance work.

[0043] When the sliding frame 13 moves, the scraping plates 17 embedded on its three surfaces are tightly against the inner wall of the receiving pool 3, removing the residue on the inner wall, ensuring the cleanliness of the inside of the receiving pool 3, and moving the impurities to the side with operating space for subsequent cleaning.

[0044] The electric telescopic rod 11 can adjust the height of the receiving pool 3 relative to the roller body 2, so that part of the coolant directly contacts the roller body 2 for immersion cooling. This process can be carried out synchronously or asynchronously with the spray cooling to adapt to different operating requirements.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
