However, in actual use, due to the movement of the coolant, it may contact with impurities in the pipeline during the movement and drive the impurities to flow. When there are too many impurities, the heat dissipation effect may be affected. Utility Model Content

[0006] Preferably, the filter plate is arranged between the fixed plate and the limit plate, and the upper outer wall of the filter plate contacts the lower outer wall of the limit plate in the initial state. By setting the position of the filter plate, it is ensured that the filter plate will not move excessively under the drive of the water flow, so that the spring 1 is damaged under the pulling of the filter plate, thereby ensuring the service life of the parts.

[0007] Preferably, the anti-stop assembly includes a trapezoidal block, which is slidably connected to the filter plate, the trapezoidal block is fixedly connected to a control block, a spring 2 is fixedly connected below the control block, one end of the spring 2 away from the control block is fixedly connected to the inner wall of the filter plate, an alarm is fixedly connected to the outer wall of the water tank, and the switch of the alarm is arranged above the fixed plate.

[0010] The utility model provides a cooling device for circulating and filtering coolant, which has the following beneficial effects:

[0011] (1) The utility model provides a filtering mechanism. When the filter plate is blocked, the water flow drives the filter plate to move downward, and pulls the pull rope, so that the rotating rod rotates and the scraper scrapes away the impurities on the filter plate, thereby achieving the effect of automatically cleaning the filter plate.

[0012] (2) The utility model sets an anti-stop component. After the filter plate is completely blocked, the water flow pushes the trapezoidal block, so that a gap is generated between the trapezoidal block and the filter plate after the trapezoidal block moves downward, so that condensed water can flow out through the gap between the trapezoidal block and the filter plate to achieve a circulation effect. At the same time, the alarm switch is long pressed to make the alarm sound, ensuring that the cooling effect can still be achieved before the staff handles the impurities.

DETAILED DESCRIPTION

[0019] 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 of the embodiments.

[0020] Embodiment 1

[0021] See also Figure 1-4A cooling device for circulating and filtering a coolant comprises a water tank 1 and a water pipe 2. A circulating pump 3 is fixedly connected to the inner wall of the water tank 1. The water suction port of the circulating pump 3 is communicated with the water outlet of the water pipe 2. The bottom of the water tank 1 is communicated with the water inlet of the water pipe 2. A filtering mechanism 4 is arranged inside the water tank 1. The filtering mechanism 4 comprises a filtering plate 41. A spring 42 is fixedly connected to the bottom of the filtering plate 41. A fixing plate 43 is fixedly connected to the inner wall of the water tank 1. The upper end of the fixing plate 43 is fixedly connected to the spring 42. The fixed plate 43 is fixedly connected with a pull rope 44, and a rotating rod 45 is rotatably connected to the inner wall of the water tank 1. The rotating rod 45 is slidably connected with a scraper 46. The scraper 46 is slidably connected to the upper outer wall of the filter plate 41. The filter plate 41 is a solid plate-like object at the periphery and the center. The scraper 46 is slidably connected to the annular slideway opened on the solid plate-like object of the filter plate 41, and the outer wall of the scraper 46 contacts the upper surface of the filter screen in the middle of the filter plate 41. By adjusting the filter plate 41 and the scraper 46, the filter plate 41 and the scraper 46 are connected to each other. The connection relationship and position setting ensure that the scraper 46 can move up and down under the drive of the filter plate 41 without affecting the scraping effect. The end of the pull rope 44 away from the fixed plate 43 is fixedly connected to the outer wall of the rotating rod 45. The filter plate 41 is provided with an anti-stop component 47. The inner wall of the water tank 1 is fixedly connected with a limit plate 48. The filter plate 41 is arranged between the fixed plate 43 and the limit plate 48, and the upper outer wall of the filter plate 41 contacts the lower outer wall of the limit plate 48 in the initial state. By setting the position of the filter plate 41, it is ensured that the filter plate 41 will not move excessively under the drive of the water flow, so that the spring 1 42 is damaged under the pull of the filter plate 41, and the service life of the parts is guaranteed. The rotating rod 45 is connected to the inner wall of the water tank 1 through a torsion spring 49. After the filter plate 41 is blocked, the water flow drives the filter plate 41 to move downward, and pulls the pull rope 44, so that the rotating rod 45 rotates and then the scraper 46 scrapes the impurities on the filter plate 41, thereby achieving the effect of automatically cleaning the filter plate 41.

[0022] When in use, when it is necessary to start the equipment, the staff starts the circulation pump 3, so that the condensed water starts to circulate under the drive of the circulation pump 3. After the condensed water enters the water tank 1 during the circulation process, it passes through the filter plate 41 and then enters the water inlet of the water pipe 2. When the filter plate 41 is blocked during use, since the condensed water cannot pass through the filter plate 41, the condensed water drives the filter plate 41 to move downward. At this time, the filter plate 41 pulls the pull rope 44, so that the pull rope 44 drives the rotating rod 45 to rotate. Since the filter plate 41 is slidably connected to the scraper 46, when the filter plate 41 is blocked, the condensed water cannot pass through the filter plate 41. Therefore, the condensed water drives the filter plate 41 to move downward. At this time, the filter plate 41 pulls the pull rope 44, so that the pull rope 44 drives the rotating rod 45 to rotate. Since the filter plate 41 is slidably connected to the scraper 46, when the filter plate 41 is blocked, the condensed water drives the filter plate 41 to move downward. The scraper 46 is driven downward by the plate 41 during the downward movement. Since the rotating rod 45 and the scraper 46 are slidably connected, the scraper 46 rotates accordingly when the rotating rod 45 rotates, and contacts the upper outer wall of the filter plate 41 during the rotation, thereby achieving the effect of cleaning the filter plate 41. When the filter plate 41 is cleaned, the condensed water flows out through the filter plate 41. At this time, the filter plate 41 is automatically reset under the drive of the spring 42, and the pull rope 44 is in a loose state. At this time, the rotating rod 45 is automatically reset under the drive of the torsion spring 49, thereby ensuring that the device can be automatically reused.

[0023] Embodiment 2

[0024] See also Figure 1-5The anti-stop assembly 47 comprises a trapezoidal block 471, which is slidably connected to the filter plate 41. The cross-sectional shape of the trapezoidal block 471 is a trapezoid, and the shorter bottom side of the trapezoidal block 471 is arranged at the top. By setting the shape of the trapezoidal block 471, it is ensured that when the filter plate 41 is blocked, the trapezoidal block 471 can create a gap between the trapezoidal block 471 and the filter plate 41 under the push of the water flow, thereby achieving the expected effect. The trapezoidal block 471 is fixedly connected to a control block 472, and a spring 2 473 is fixedly connected to the bottom of the control block 472. The end of the spring 2 473 away from the control block 472 is fixedly connected to the inner wall of the filter plate 41. The elastic force of the spring 2 473 is greater than the elastic force of the spring 1 42. By setting the elastic force of the spring 2 473, it is ensured that the trapezoidal block 471 will be squeezed under the action of external force only when the filter plate 41 moves to a position where it cannot move downward, so as to ensure that the filter plate 41 is blocked only when the filter plate 41 is cleaned. The trapezoidal block 471 can move only after it is invalid. An alarm 474 is fixedly connected to the outer wall of the water tank 1. The switch of the alarm 474 is set above the fixed plate 43. The switch of the alarm 474 is in the closed state in the initial state. The switch of the alarm 474 is made of rubber. When the switch of the alarm 474 is in the long-pressed state, the alarm 474 sounds an alarm, and when it is short-pressed or not pressed, the alarm 474 does not sound, ensuring that when blocked impurities are generated on the filter plate 41 but the alarm 474 is in a state where it can be automatically cleaned, the alarm 474 will not sound. After the filter plate 41 is completely blocked, the water flow pushes the trapezoidal block 471, so that after the trapezoidal block 471 moves downward, a gap is generated between the filter plate 41, so that the condensed water can flow out through the gap between the trapezoidal block 471 and the filter plate 41 to achieve a circulation effect. At the same time, long pressing the alarm 474 switch makes the alarm 474 sound, ensuring that the cooling effect can still be achieved before the staff handles the impurities.

[0025] During use, on the basis of Example 1, when the impurities on the filter plate 41 cannot be scraped off by the scraper 46, the filter plate 41 is driven by the condensed water to move downward. When the filter plate 41 moves to a state where it cannot move further downward, the water flow pushes the trapezoidal block 471 to move downward, thereby creating a gap between the trapezoidal block 471 and the filter plate 41. At this time, the condensed water flows out through the gap between the trapezoidal block 471 and the filter plate 41 to achieve a circulation effect. At the same time, the filter plate 41 long presses the switch of the alarm 474, causing the alarm 474 to sound, reminding the staff to deal with the impurities on the filter plate 41.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
