[0021] Example 1 A preferred embodiment of the cooling tower for the air compressor station in the chemical workshop provided by this utility model is as follows: Figures 1 to 6As shown: The air compressor station cooling tower in the chemical workshop includes a tower body 12; a cooling water output pipe 6 fixedly connected to one side of the bottom end of the tower body 12, a cleaning pipe 4 fixedly connected to the lower end of one side of the tower body 12, and a drain pipe 7 fixedly connected to the other side of the bottom end of the tower body 12; a cleaning assembly 5 assembled inside the lower end of the tower body 12, which is used for scraping and cleaning the lower end of the inner wall of the tower body 12; and ventilation slots 14 opened at equal angles at the lower end of the tower body 12, with filter grids engaged on the inner wall of the ventilation slots 14. 2. Filter cotton 3 is inserted inside the filter grid 2; the mounting assembly 8 is assembled on the filter grid 2 and the ventilation slot 14, and the mounting assembly 8 is used to detach and install the filter grid 2 from the inner wall of the ventilation slot 14; the packing 9 is fixedly connected to the upper end of the inner wall of the tower body 12, and the inner wall of the tower body 12 above the packing 9 is fixedly connected to the water distribution frame 10, and the top side of the water distribution frame 10 is fixedly connected to a cooling water delivery pipe 1 extending to the outside of the tower body 12, and the top of the inside of the tower body 12 is fixedly connected to a fan 13.

[0022] It should be noted that some existing cooling towers in air compressor stations of chemical workshops still have certain shortcomings in actual use. After long-term use, some scale and impurities will accumulate in the water collection pan at the bottom of the cooling tower. These impurities will affect the circulation and transportation of cooling water. However, cleaning them is currently quite cumbersome and inconvenient, and will increase the labor intensity of the staff.

[0023] In a further preferred embodiment of this utility model, the cleaning component 5 includes: a drive motor 501 fixedly connected to the middle position of the bottom end of the tower body 12, the output end of the drive motor 501 extending into the interior of the tower body 12 and fixedly connected to a rotating rod 506 via a coupling, a bolt hole 504 being provided at the middle position of the top end of the rotating rod 506, and a slot 505 being provided on one side of the top end of the rotating rod 506; a fixing sleeve 508 engaging with the upper surface of the rotating rod 506, a fixing bolt 503 being movably connected to the top end of the fixing sleeve 508 and threadedly engaged with the inside of the bolt hole 504, a locking block 507 being fixedly connected to one side of the inner wall of the fixing sleeve 508, and a scraper 502 being fixedly connected to one side of the bottom end of the fixing sleeve 508.

[0024] In this embodiment, cleaning fluid is added through cleaning pipe 4, and after a period of reaction, drive motor 501 is started to drive rotating rod 506 to rotate, thereby causing fixed sleeve 508 and scraper 502 to rotate, scraping and cleaning the lower end of the inner wall of tower body 12, scraping off the scale and impurities adhering thereto. Then, the valve on drain pipe 7 is opened, and scraper 502 continues to rotate, discharging sewage and impurities together through drain pipe 7.

[0025] In a further preferred embodiment of the present invention, the scraper 502 is L-shaped, and one side of the scraper 502 is arc-shaped.

[0026] In this embodiment, an L-shaped scraper 502 is used to facilitate scraping and cleaning of the inner bottom wall and the lower end of the inner wall of the tower body 12.

[0027] In a further preferred embodiment of the present invention, the card block 507 and the card slot 505 form an engaging structure, and the card slot 505 and the card block 507 are convex in shape.

[0028] In this embodiment, the engagement between the convex locking block 507 and the inside of the locking groove 505 is used to improve the engagement strength between the fixing sleeve 508 and the top of the rotating rod 506.

[0029] Example 2 Based on Example 1, a preferred embodiment of the cooling tower for the air compressor station in the chemical workshop provided by this utility model is as follows: Figures 1 to 6 As shown: The installation component 8 includes: positioning grooves 801 symmetrically opened on both sides of the bottom wall of the ventilation slot 14; an installation groove 805 is opened inside the tower body 12 on the inner wall of the positioning groove 801; an installation spring 806 is fixedly connected to the inner wall of the installation groove 805; an installation block 802 extending into the positioning groove 801 is fixedly connected to one end of the installation spring 806; a lever 807 extending to the outside of the tower body 12 is fixedly connected to one side of the installation block 802; and positioning blocks 808 symmetrically fixedly connected on both sides of the bottom end of the filter grid 2; an installation hole 809 is opened on one side of the positioning block 808.

[0030] In this embodiment, the filter grid 2 is pulled by the handle on the filter grid 2 to detach it from the ventilation groove 14, which facilitates the disassembly and cleaning of the filter grid 2 and the removal and replacement of the filter cotton 3. During installation, the filter grid 2 is snapped into the ventilation groove 14, and the elastic force of the installation spring 806 is used to make the installation block 802 slide into the installation hole 809, so as to realize the quick assembly and disassembly of the filter grid 2 and the ventilation groove 14.

[0031] In a further preferred embodiment of the present invention, the mounting block 802 and the mounting hole 809 form an engaging structure, and the mounting block 802 and the mounting hole 809 are symmetrically distributed about the vertical central axis of the ventilation groove 14.

[0032] In this embodiment, the engagement between the mounting block 802 and the mounting hole 809 ensures the secure and stable engagement between the positioning block 808 and the positioning groove 801.

[0033] In a further preferred embodiment of the present invention, a sliding groove 804 is provided on the inner wall of the mounting groove 805, and two ends of one side of the mounting block 802 are fixedly connected to sliders 803 that slide in cooperation with the inside of the sliding groove 804.

[0034] In this embodiment, the sliding of the slider 803 inside the groove 804 is used to improve the smoothness of the sliding of the mounting block 802.

[0035] In a further preferred embodiment of the present invention, the positioning block 808 and the positioning groove 801 form an engaging structure, and one end of the positioning groove 801 and the positioning block 808 are arc-shaped.

[0036] In this embodiment, the use of the arc-shaped positioning groove 801 and positioning block 808 ensures that the filter grid 2 will not protrude from the surface of the tower body 12 after it is engaged with the positioning block 808.

[0037] In a further preferred embodiment of the present invention, water baffles 11 are fixedly connected at equal intervals to the upper end of the inner wall of the tower body 12, and the shape of the water baffles 11 is an inverted V shape.

[0038] In this embodiment, the use of the inverted V-shaped baffle plate 11 can reduce the discharge of water vapor and improve the water resource utilization rate.

[0039] In summary, firstly, the cooling water delivery pipe 1 and cooling water output pipe 6 are connected to the cooling water circulation pipe of the air compressor station. Then, the hot cooling water is delivered to the inside of the water distribution frame 10 through the cooling water delivery pipe 1 and then sprayed evenly downwards. At the same time, the fan 13 is started to filter the outside air through the filter grid 2 and filter cotton 3 and then enter the tower body 12 and be delivered upwards. The air then exchanges heat with the sprayed water, so that the air after heat exchange is discharged through the top of the tower body 12. The water after heat exchange is cooled and flows to the lower end of the tower body 12 for storage. At the same time, the inverted V-shaped baffle 11 can deflect the diffused water vapor, reduce the discharge of water vapor, and improve the water resource utilization rate. Meanwhile, when cleaning is required, first stop the supply of cooling water between the air compressor station and the tower body 12, then add cleaning fluid through the cleaning pipe 4, and after a period of reaction, start the drive motor 501 to drive the rotating rod 506 to rotate, which in turn causes the fixed sleeve 508 and scraper 502 to rotate, scraping and cleaning the lower end of the inner wall of the tower body 12 to remove the scale and impurities adhering to it. Then open the valve on the drain pipe 7, and at the same time, the scraper 502 continues to rotate, discharging the sewage and impurities together through the drain pipe 7. At the same time, the fixing bolt 503 can be loosened with a screwdriver or other tools until it is completely separated from the bolt hole 504. Then pull the fixed sleeve 508 to separate it from the rotating rod 506, making it easy to disassemble the scraper 502 and the fixed sleeve 508 for maintenance or replacement. When installing, put the fixed sleeve 508 on the rotating rod 506 and make the locking block 507 lock into the slot 505. Then tighten the fixing bolt 503 into the bolt hole 504. Furthermore, when cleaning and maintenance of the filter grid 2 and filter cotton 3 are required, the mounting block 802 can be slid inside the mounting groove 805 by moving the locking block 507 to compress the mounting spring 806 until it is completely disengaged from the mounting hole 809. Then, the filter grid 2 can be pulled by the handle on the filter grid 2 to disengage it from the ventilation groove 14, making it easy to disassemble and clean the filter grid 2 and remove and replace the filter cotton 3. During installation, the mounting block 802 is slid by moving the locking block 507 first, and then the filter grid 2 is locked into the ventilation groove 14. Then, the positioning block 808 is locked into the positioning groove 801. After that, the locking block 807 is released, and the mounting block 802 is slid into the mounting hole 809 by the elastic force of the mounting spring 806, so that the filter grid 2 and the ventilation groove 14 can be quickly disassembled and assembled.
