[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for removing impurities from the cooling water of a precooling machine.

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

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] A device for removing impurities from cooling water in a precooling machine, such as Figures 1 to 6As shown, the device includes a box body 1, with a partition 4 welded to the bottom of the box body 1 and a telescopic pipe installed on the top of the box body 1. A drain pipe 27 is welded to the inner wall of the partition 4, and a drain tray 13 is welded to the top of the drain pipe 27. A sealing gasket 25 is fixed to the top of the drain tray 13. A guide rod 10 is welded to the outer wall of the top of the box body 1, and the telescopic pipe and the guide rod 10 are slidably connected. A connecting seat 24 is slidably connected to the outer wall of the guide rod 10, and a filter screen 26 is welded to the inner wall of the connecting seat 24. The telescopic component, the connecting seat 24, and the guide rod 10 are limited by a limiting component.

[0030] The cooling water for the precooler can be transported using telescopic pipe fittings. When it is necessary to remove impurities from the cooling water for the precooler, the connecting seat 24 and the guide rod 10 are first slidably connected. The guide rod 10 is used to position the connecting seat 24. When the bottom of the connecting seat 24 moves to fit against the surface of the sealing gasket 25, the sealing gasket 25 improves the sealing between the connecting seat 24 and the drain pan 13, preventing leakage during the removal of impurities from the cooling water for the precooler.

[0031] After the connector 24 is installed, the telescopic pipe is slid along the guide rod 10 so that the bottom of the telescopic pipe and the top of the connector 24 fit together. The limiting component limits the telescopic component, the connector 24 and the guide rod 10 to ensure the relative stability of the three. When the precooling water is input through the telescopic pipe, the filter screen 26 can filter the impurities in the precooling water. After the precooling water is filtered, it enters the drain pan 13 and the drain pipe 27 after passing through the connector 24.

[0032] The telescopic pipe fitting includes a bracket 2 and a flange 9. The bracket 2 is fixed to the top outer wall of the box 1 by bolts, and the flange 9 is welded to one end of the bracket 2. The bottom of the flange 9 is fixed with a telescopic corrugated pipe 8, and the bottom of the telescopic corrugated pipe 8 is fixed with a sealing seat 20. The sealing seat 20 and the guide rod 10 are slidably connected, and the bottom of the sealing seat 20 is fixed with a sealing gasket 22.

[0033] The telescopic bellows 8 can extend and retract. Therefore, after the flange 9 is fixed to the top of the box 1 by the bracket 2, the telescopic bellows 8 can be used to slide the connection between the connecting seat 24 and the guide rod 10. This allows the sealing seat 20 and the guide rod 10 to slide together until the sealing gasket 22 at the bottom of the sealing seat 20 and the top of the connecting seat 24 are in contact. When it is necessary to remove impurities from the precooling water, the flange 9 can be connected to the precooling water delivery pipe (not shown).

[0034] The limiting assembly includes a handle 3, a rotating disk 23, and a rotating shaft 28. The rotating shaft 28 is rotatably connected to the inner wall of a through hole on one side of the housing 1. A torsion spring 16 is installed between the outer circumference of the rotating shaft 28 and the side wall of the housing 1. The handle 3 is welded to one end of the rotating shaft 28. The rotating disk 23 is fixed to the other end of the rotating shaft 28 by a pin. Sliding rods 12 are slidably connected to both sides of the housing 1. A U-shaped frame 19 is welded to one end of the sliding rod 12. A swing arm 11 is rotatably connected between the U-shaped frame 19 and the rotating disk 23. A limiting rod 7 is welded to the end of the sliding rod 12 away from the U-shaped frame 19 through a drive plate 6. A limiting groove 21 that cooperates with the limiting rod 7 is opened on the side wall of the sealing seat 20.

[0035] During the installation of the connecting seat 24, the operator first holds the handle 3 to rotate the rotating shaft 28 and the rotating disk 23. The swing arm 11 can convert the circular motion of the rotating disk 23 into the linear motion of the slide rod 12 and the U-shaped frame 19, thereby causing the limiting rod 7 to move away from the guide rod 10. After the connecting seat 24 is installed and the sealing gasket 22 and the top of the connecting seat 24 are in contact, the handle 3 is released. The rebound force of the torsion spring 16 causes the two sets of limiting rods 7 to move relative to each other. Finally, the two sets of limiting rods 7 are inserted into the inner walls of the limiting grooves 21 on both sides of the sealing seat 20, thereby using the limiting rods 7 and the limiting grooves 21 to limit the telescopic component, the connecting seat 24 and the guide rod 10.

[0036] The bottom of the partition 4 is welded to the box body 5, and a drain valve 14 is fixed to one side of the outer wall of the box body 5 by bolts.

[0037] The precooling water after impurity removal can be stored in the second box 5. When the precooling water after impurity removal is needed, the drain valve 14 is opened to discharge the precooling water after impurity removal.

[0038] Working principle: First, the connecting seat 24 is slidably connected along the guide rod 10. The guide rod 10 is used to precisely position the connecting seat 24. When the bottom of the connecting seat 24 moves to a tight fit with the surface of the sealing gasket 25, the sealing gasket 25 will significantly improve the sealing performance between the connecting seat 24 and the drain pan 13, effectively preventing leakage of the precooling water during the impurity removal process. Utilizing the telescopic properties of the telescopic bellows 8, the sealing seat 20 is slid along the guide rod 10 to a tight fit with the top of the connecting seat 24. At this time, a seal is formed between the sealing gasket 22 at the bottom of the sealing seat 20 and the top of the connecting seat 24, ensuring the sealing performance of the precooling water during the transportation process. During the installation of the connecting seat 24, the handle 3 is held to rotate the rotating shaft 28 and the rotating disk 23. The swing arm 11 converts the circular motion of the rotating disk 23 into the linear motion of the slide rod 12 and the U-shaped frame 19. The movement causes the limiting rod 7 to move away from the guide rod 10. After the connecting seat 24 is installed and the sealing gasket 22 is tightly fitted to the top of the connecting seat 24, the release handle 3 uses the rebound force of the torsion spring 16 to make the two sets of limiting rods 7 move relative to each other, and finally insert into the inner wall of the limiting groove 21 on both sides of the sealing seat 20, so as to achieve stable limiting between the telescopic component, the connecting seat 24 and the guide rod 10. The flange 9 is connected to the precooling machine cooling water supply pipeline. When the precooling machine cooling water passes through the connecting seat 24, the filter screen 26 is used to filter the impurities in the water. The filtered precooling machine cooling water flows into the second box 5 through the drain pan 13 and the drain pipe 27 for storage. The second box 5 is used to store the precooling machine cooling water after impurity removal. When the precooling machine cooling water after impurity removal is needed, simply open the drain valve 14 on one side of the second box 5, and the cooling water can be discharged smoothly for subsequent use.

[0039] Example 2

[0040] A precooling machine cooling water impurity removal device, to facilitate the removal of the connecting seat 24 and filter screen 26 from the guide rod 10, such as... Figures 1 to 6 As shown, this embodiment makes the following additions based on embodiment 1: the outer circumference of the rotating shaft 28 is fixed with an arc-shaped extrusion plate 15 by a pin, and the side wall of the sealing seat 20 is fixed with a sliding plate 18 by screws, and the bottom of the sliding plate 18 is fixed with a lifting plate 17 by screws.

[0041] When it is necessary to remove the connecting seat 24 and the filter screen 26 to clean the impurities trapped on the surface of the filter screen 26, when the handle 3 is held and the rotating shaft 28 is rotated, the rotating shaft 28 causes the arc-shaped extrusion plate 15 to rotate synchronously. When the limiting rod 7 and its corresponding limiting groove 21 are separated from each other, the arc-shaped extrusion plate 15 moves toward the bottom of the lifting plate 17. The arc-shaped extrusion plate 15 can be used to lift the lifting plate 17 and the sliding plate 18, so that when the connecting seat 24 and the filter screen 26 are removed, the sealing seat 20 is in a lifted state by the lifting plate 17 and the sliding plate 18, which makes it easy to remove the connecting seat 24 and the filter screen 26 from the guide rod 10.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
