Description

Technical Field

[0001] The utility model belongs to the technical field of purification treatment devices, and particularly relates to a cooling water reflux purification treatment device. Background Art

[0002] During the circuit board processing, a cooling device is required to cool the processing equipment and the circuit board, etc., so as to ensure that the processing equipment and the circuit board can be in a stable state.

[0003] Chinese Patent with Publication No. CN221014772U discloses an industrial circulating water treatment device, which includes a treatment tank. In the middle of the inner wall at the top of the treatment tank, a motor is fixedly connected. The driving end of the motor is fixedly connected with a rotating rod. The bottom end of the rotating rod is fixedly connected with a connecting ring. The outer diameters of the left and right ends of the connecting ring are fixedly connected with connecting rods. One end of the outer side of each connecting rod is fixedly connected with a connecting column. By starting the motor to drive the rotating rod to rotate, the rotating rod is connected to the connecting ring, and the connecting ring is connected to the connecting rods. When the rotating rod rotates, it drives the connecting rods to rotate. The connecting rods are connected to the connecting columns, and the cleaning rods are connected to the connecting columns. When the connecting rods rotate, they drive the cleaning rods to rotate, and during the process of cleaning the inner wall, scale can be removed, preventing the scale from affecting the tank body, and reducing the labor intensity of the staff and improving work efficiency.

[0004] However, in the actual use process, although the scale adhered to the inner wall can be scraped off by the scraping method, the scale still exists in the treatment tank, resulting in the probability that the scale adheres to the inner wall or the hollow filter column at any time, and the area after scraping is still likely to be adhered by the scale, that is, the scale that cannot be discharged from the treatment tank will reduce the filtering effect of the hollow filter column. Content of the Utility Model

[0005] The utility model aims to provide a cooling water reflux purification treatment device to solve the problem that the scale that cannot be discharged from the treatment tank will reduce the filtering effect mentioned above.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A cooling water reflux purification treatment device includes a treatment tank, and also includes

[0007] A scraping mechanism, which includes a driving unit and a scraping unit. The driving unit is installed on the top of the treatment tank, and the scraping unit is installed in the treatment tank. The driving unit is used to drive the scraping unit to rotate;

[0008] A collection mechanism, which includes a collection box and a filter bag. A receiving groove is opened on the outer wall of the treatment tank, and two water permeable holes communicating with the receiving groove are opened on the inner wall of the treatment tank. The collection box is fixed in the receiving groove, the filter bag is installed in the collection box, the filter bag has an opening, and the opening corresponds to one of the water permeable holes.

[0009] Principle and effect of this technical solution:

[0010] 1. The inner side of the treatment tank is scraped by a scraping mechanism. At the same time, the rotation of the scraping unit can drive the stored water inside the treatment tank to rotate in one direction, so that the scale scraped off will not sink to the bottom, but rotate with the rotation of the water flow, and there will be a certain undulation. And through the setting of the collection mechanism, the scale or impurities will enter the collection mechanism under the action of centrifugal force during rotation and be intercepted by the collection mechanism, thus avoiding the situation that the scale and impurities float randomly in the treatment tank after being scraped, which affects the filtration effect, that is, improving the filtration effect of the treatment tank.

[0011] 2. By opening two water-permeable holes and making the opening of the filter bag correspond to one water-permeable hole, when the accumulated water in the treatment tank rotates in one direction, the accumulated water and impurities in the treatment tank will first enter the water-permeable hole at the opening of the filter bag under the action of centrifugal force, and then flow out from the water-permeable hole on the other side of the stored water, and the impurities are intercepted by the filter bag, thus cleaning and removing the impurities and scale in the treatment tank, thereby improving the filtration effect of the treatment tank.

[0012] The present utility model is further provided that: the scraping unit includes a rotating frame and an outer scraping plate. The rotating frame is rotatably installed in the treatment tank. The rotating frame is connected to the driving unit. The outer scraping plate is installed on the side wall of the rotating frame, and the outer scraping plate abuts against the inner wall of the treatment tank.

[0013] Principle and effect of this technical solution: By connecting the rotating frame to the driving unit, the rotation of the rotating frame can drive the outer scraping plate to scrape the inner wall of the treatment tank, so that the scale and impurities adhering to the inner wall of the treatment tank can rotate with the rotation of the internal stored water, so that the scale can enter the collection bag under the drive of centrifugal force during rotation, or precipitate to the bottom of the inner side of the treatment tank, and then the scale and impurities are discharged through subsequent drainage and slag discharge.

[0014] The present utility model is further provided that: the scraping unit further includes a bottom scraping plate. The cross-section of the rotating frame is in an inverted U shape, and the bottom scraping plate is fixed to the bottom end of the rotating frame.

[0015] Principle and effect of this technical solution: Through the setting of the bottom scraping plate, the impurities and scale deposited at the bottom of the inner side of the treatment tank can be scraped and driven, so that the deposited impurities and scale can be collected by the collection mechanism under the drive of rotation. At the same time, the scale accumulated at the bottom of the treatment tank can be softened, making it easier for subsequent drainage and scale removal.

[0016] The present utility model is further provided that: the bottom of the bottom scraping plate has a notch, and a ball is installed in the notch. The ball abuts against the inner bottom surface of the treatment tank.

[0017] Principle and effect of this technical solution: Through the settings of the notch and the ball, the bottom scraper and the bottom inside the treatment tank are converted into rolling contact, reducing the friction. At the same time, the bottom surface of the bottom scraper can be slightly higher than the bottom inside the treatment tank, so that the bottom scraper can rotate more smoothly.

[0018] The present utility model is further configured as: The interior of the treatment tank has a hollow filter column. The hollow filter column is located inside the rotating frame. The scraping unit further includes an inner scraper. The inner scraper is fixed to the bottom scraper and abuts against the outer wall of the hollow filter column.

[0019] Principle and effect of this technical solution: Through the setting of the inner scraper, when the scraping unit rotates, it can not only scrape the inner wall of the treatment tank, but also scrape the outer wall of the hollow filter column, thereby removing impurities and scale adhering to the outer wall of the hollow filter column, and then improving the filtering efficiency of the hollow filter column.

[0020] The present utility model is further configured as: The cross-section of the inner scraper is in an inverted U shape, and the top surface inside the inner scraper abuts against the top surface of the hollow filter column.

[0021] Principle and effect of this technical solution: By making the top surface inside the inner scraper abut against the top surface of the hollow filter column, when the scraping unit rotates, it can synchronously drive the inner scraper to scrape the top surface of the hollow filter column, thereby preventing scale or other impurities from accumulating on the top surface of the hollow filter column and affecting the filtering effect of the hollow filter column.

[0022] The present utility model is further configured as: The driving unit includes a motor and a rotating shaft. The motor is fixed to the top surface of the treatment tank. The rotating shaft is rotatably installed at the top of the treatment tank, and one end of the rotating shaft is connected to the movable end of the motor, and the other end of the rotating shaft is connected to the scraping unit.

[0023] Principle and effect of this technical solution: The motor drives the rotating shaft to rotate, so that the rotating shaft can extend into the treatment tank to drive the scraping unit to rotate, and at the same time, the rotation of the scraping unit drives the stored water and scale in the treatment tank to rotate.
