Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower water inlet, in particular to a cross-flow cooling tower water inlet device. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It cools by exchanging heat between water and air flow to produce steam, which evaporates and takes away heat to achieve evaporative heat dissipation.

[0003] The existing filter plate is welded inside the filter housing, which can fix the position of the filter plate. However, the filter plate needs to be replaced after long-term use. When replacing, the filter plate needs to be cut, which takes a lot of time to replace.

[0004] The prior art proposes a Chinese patent with publication number CN220437229U to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a cross-flow cooling tower water inlet device, including a cooling tower body and a supporting iron frame, the front end of the cooling tower body is threadedly connected with a handrail frame, the top surface of the cooling tower body is fixedly connected with a water inlet pipe, the right side surface of the water inlet pipe is threadedly connected with a connecting mechanism, the inner wall surface of the connecting mechanism is threadedly connected with a filtering mechanism, the supporting iron frame is threadedly connected to the bottom surface of the cooling tower body, and the filtering mechanism includes a limit unit and a filtering unit, and the limit unit and the filtering unit are arranged in sequence from front to back. The cross-flow cooling tower water inlet device, by providing a filter plate, a metal latch and a connecting block, can plug the filter plate, can quickly replace the filter plate, and is convenient to clean the surface of the filter plate, thereby increasing the use time of the device, allowing the filter plate to slide inside the filter housing, and can reduce the wear of the filter plate.

[0005] Although the prior art can quickly replace the filter plate and facilitate cleaning the surface of the filter plate, thereby increasing the service life of the device, the staff is required to disassemble the filter plate each time it is cleaned. After cleaning, it needs to be installed again before the cooling tower can be cooled again. This increases the labor intensity of the staff and affects the overall efficiency of the cooling tower.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The present invention is further described in detail below in conjunction with the embodiments:

[0029] Example 1

[0030] like Figure 1-5 As shown, the utility model provides a cross-flow cooling tower water inlet device, including a cooling tower water inlet filter device 1, a hydraulic push rod 2 and a filter plate 7, the outer wall of the filter plate 7 is fixedly connected to the inner wall of the cooling tower water inlet filter device 1, and a cleaning assembly 8 is arranged below the filter plate 7.

[0031] The cleaning assembly 8 includes a cleaning roller 9 for cleaning the bottom surface of the filter plate 7, a brush strip shrapnel 10 rotatably connected to the outer wall at both ends of the cleaning roller 9, a gear 11 fixedly connected at both ends of the cleaning roller 9, and a rack 12 meshing with the bottom surface of the gear 11.

[0032] One side of the brush strip spring 10 is fixedly connected to a connecting rod 3, the outer wall of the connecting rod 3 is movably connected to the front of the cooling tower water inlet filter device 1 through a sealing shaft 4, and the other end of the connecting rod 3 is fixedly connected to the telescopic end of the hydraulic push rod 2.

[0033] The outer wall of the cleaning roller 9 is staggered with external scraping strips 14 distributed alternately with the brush strips, one side of the brush strip spring 10 is fixedly connected with an elastic scraper 15, and the inner wall of the elastic scraper 15 is fixedly connected with a reset spring 16 fixedly connected to one side of the brush strip spring 10. In the process of the cleaning roller 9 rotating and moving forward, the external scraping strips 14 on its outer wall will overlap the top side of the elastic scraper 15 during the rotation process, and at the same time, the elastic scraper 15 is intermittently hit, and the elastic scraper 15 is reset by the reset spring 16. The elastic scraper 15 is divided into two groups, which are respectively placed on both sides of the brush strip spring 10, so as to scrape and clean the external scraping strips 14 and the brush strips, which is convenient for the subsequent cleaning roller 9 to clean the filter plate 7.

[0034] One end of the brush bar spring piece 10 is fixedly connected to a side slider 17, the inner wall of the rack 12 is provided with a side slide groove 13, and the outer wall of the side slider 17 is slidably connected to the inner wall of the side slide groove 13. During the cleaning process of the filter plate 7, the bottom of the cooling tower water inlet filter device 1 can be connected to a sewage pipe to discharge the blockage in the cleaning process without disassembling the filter plate 7, thereby avoiding the problem of efficiency impact on the operation of the equipment caused by disassembly and installation.

[0035] Example 2

[0036] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, one side of the rack 12 is fixedly connected to the inner wall of the cooling tower water inlet filter device 1.

[0037] The outer wall of the hydraulic push rod 2 is fixedly connected to the outer wall of the cooling tower water inlet filter device 1 through a mounting seat.

[0038] A water inlet pipe 5 is fixedly connected to one side of the cooling tower water inlet filter device 1 , and a water outlet pipe 6 is fixedly connected to the other side of the cooling tower water inlet filter device 1 .

[0039] The following is a detailed description of the working principle of the cross-flow cooling tower water inlet device.

[0040] like Figure 1-5 As shown, during use, when the filter plate 7 needs to be cleaned, the external power supply starts the hydraulic push rod 2, so that the hydraulic push rod 2 pushes the connecting pull rod 3 to drive the cleaning roller 9 on the brush strip spring 10 to move forward. The cleaning roller 9 will drive the gear 11 in the process of moving forward, and the gear 11 will be affected by the rack 12, driving the cleaning roller 9 to rotate and move forward. At this time, the brush strip on the outer wall of the cleaning roller 9 and the external scraper strip 14 will scrape and clean the bottom surface of the filter plate 7. Since the cleaning roller 9 is in the process of rotating and moving forward, the brush strip on the cleaning roller 9 and the external scraper strip 14 can quickly and evenly clean the blockage on the cleaning roller 9.

[0041] When the cleaning roller 9 is reset, it is turned over to perform a second cleaning on the bottom surface of the filter plate 7, thereby further improving the cleaning effect.

[0042] During the cleaning process of the filter plate 7, the bottom of the cooling tower water inlet filter device 1 can be connected to the sewage pipe to discharge the blockages in the cleaning process without disassembling the filter plate 7, thereby avoiding the problem of efficiency impact on equipment operation caused by disassembly and installation.

[0043] During the process of the cleaning roller 9 rotating forward, the external scraper strip 14 on its outer wall will overlap the top side of the elastic scraper plate 15 during the rotation process, and at the same time intermittently hit the elastic scraper plate 15, and the elastic scraper plate 15 is reset by the reset spring 16. The elastic scraper plate 15 is divided into two groups, which are respectively placed on both sides of the brush bar shrapnel 10, so as to scrape and clean the external scraper strip 14 and the brush bar, thereby facilitating the subsequent cleaning roller 9 to clean the filter plate 7.

[0044] When the brush strip 10 moves forward, the side slider 17 slides on the inner wall of the side slot 13 to guide and limit the movement of the brush strip 10 so that the moving trajectory of the cleaning roller 9 can be parallel to the bottom surface of the filter plate 7.

[0045] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
