The wastewater treatment device has problems such as uneven mixing and low filtration efficiency when mixing the purifying agent and filtering the wastewater, which cannot meet the production needs. Therefore, a semiconductor grinding wastewater treatment device is proposed to solve the problems mentioned above. Summary of the Invention

It solves the problems of existing semiconductor grinding wastewater treatment devices, which require effective purification treatment before discharge or recycling due to the large amount of particulate matter and chemical impurities in the semiconductor grinding wastewater. The wastewater treatment device also suffers from uneven mixing and low filtration efficiency when mixing the purifying agent and filtering the wastewater, thus failing to meet production needs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a semiconductor grinding wastewater treatment device, comprising a tank, a sealing cover detachably installed on the upper surface of the tank, and a controller fixedly installed outside the tank. A mixing mechanism is provided outside the tank, and a pressurizing mechanism extending into the tank is provided on the upper surface of the sealing cover.

[0015] Compared with the prior art, the present invention provides a semiconductor grinding wastewater treatment device, which has the following beneficial effects:

[0016] 1. This semiconductor grinding wastewater treatment device starts the drive motor through the controller, which drives the rotating disk to rotate. Under the drive of the connecting rod and the rotating disk, the frame can reciprocate in the mixing tank.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4 This embodiment of a semiconductor grinding wastewater treatment device includes a tank 1, a sealing cover 2 detachably installed on the upper surface of the tank 1, and a controller 3 fixedly installed on the outside of the tank 1. A mixing mechanism is provided on the outside of the tank 1, and a pressurizing mechanism extending into the inside of the tank 1 is provided on the upper surface of the sealing cover 2. The mixing mechanism includes a mixing box 4 fixedly installed on the outside of the tank 1, a drive motor 5 fixedly installed on the outside of the mixing box 4, a rotating disk 6 fixedly installed on the output shaft of the drive motor 5, a connecting rod 7 hinged to the upper surface of the rotating disk 6, and a frame 8 hinged to the end of the connecting rod 7 away from the rotating disk 6.

[0025] The mixing tank 4 is externally fixedly connected to a connecting seat. The drive motor 5 is bolted to the upper surface of the connecting seat, and the connecting rod 7 is oscillatingly connected to the upper surface of the rotating disk 6. The controller 3 starts the drive motor 5, causing the rotating disk 6 to rotate. This causes the frame 8 to reciprocate within the mixing tank 4 under the influence of the connecting rod 7 and the rotating disk 6. This reciprocating motion generates strong vibrations and shear forces between the wastewater and the purifying agent, achieving rapid and uniform mixing, improving mixing efficiency, ensuring effective wastewater treatment, and achieving the advantage of high-efficiency treatment.

[0026] Specifically, the frame 8 is oscillatingly connected to the inside of the mixing tank 4. The frame 8 has several through holes inside, and its outer diameter matches the inner diameter of the mixing tank 4. The reciprocating motion of the frame 8 ensures thorough contact and mixing between the wastewater and the purifying agent, preventing localized excessively high or low concentrations and thus improving the overall wastewater treatment effect. Vibration mixing prevents particulate matter from settling in the wastewater, keeping it suspended during mixing and further enhancing the purifying agent's effectiveness. For semiconductor grinding wastewater containing large amounts of particulate matter and chemical impurities, vibration mixing better disperses the particles, allowing the purifying agent to effectively target the impurities in the wastewater.

[0027] It should be noted that slides 9 are fixedly connected to both the left and right sides of the frame 8. The slides 9 are in the shape of an inverted U and are slidably connected to the mixing box 4.

[0028] In this embodiment, the pressurization mechanism includes a fixed base 10 fixedly connected to the top of the sealing cover 2, a servo motor 11 fixedly installed on the back of the fixed base 10, a transmission gear 12 fixedly connected to the output shaft of the servo motor 11, a driven gear 13 rotatably connected to the outside of the fixed base 10, a connecting shaft 14 rotatably connected to the outside of the driven gear 13, a piston rod 15 rotatably connected to the left end of the connecting shaft 14, and a pressure plate 16 fixedly connected to the bottom end of the piston rod 15. The servo motor 11 is started by the controller 3, driving the transmission gear 12 to rotate. The driven gear 13 and the connecting shaft 14 drive the piston rod 15 to reciprocate up and down. The pressure plate 16 at the bottom of the piston rod 15 moves up and down within the tank 1, pressurizing and filtering the wastewater. This allows the wastewater to pass through layers such as the filter screen 20 for rapid filtration, removing tiny particles and pollutants. This effectively increases the filtration pressure, accelerates the filtration speed, and improves the filtration efficiency, achieving the advantages of high practicality.

[0029] The servo motor 11 is electrically connected to the controller 3, the transmission gear 12 and the driven gear 13 are meshed with each other, and the piston rod 15 is slidably connected to the upper surface of the sealing cover 2 and extends into the interior of the tank 1.

[0030] Specifically, a limiting plate 17 is fixedly connected inside the tank 1, and a conveying pipe is fixedly connected between the tank 1 and the mixing box 4. The limiting plate 17 has an opening inside that matches the piston rod 15. The reciprocating motion of the piston rod 15 ensures that the wastewater is evenly pressurized within the filtration chamber, preventing excessively high or low pressure in certain areas, thereby improving the overall wastewater treatment effect. Pressure filtration prevents the sedimentation of particulate matter in the wastewater, keeping it suspended during the filtration process and further enhancing the filtration efficiency.

[0031] In this embodiment, a filter assembly is provided at the bottom of the tank 1. The filter assembly includes a connecting pipe 19 fixedly connected to the bottom of the tank 1, a filter box 18 fixedly connected to the bottom of the connecting pipe 19, and two filter screens 20 slidably connected inside the filter box 18. The filter box 18 has an inspection port adapted to the filter screens 20, and an inspection plate is detachably installed on the outside of the inspection port. By providing two filter screens 20, the filtration efficiency can be further improved. The inspection port also facilitates the replacement and maintenance of the filter screens 20.

[0032] The working principle of the above embodiments is as follows:

[0033] During use, wastewater enters the mixing tank 4. The controller 3 starts the drive motor 5, which drives the rotating disk 6 to rotate. This causes the frame 8 to reciprocate within the mixing tank 4 under the influence of the connecting rod 7 and the rotating disk 6. This reciprocating motion generates strong vibration and shear force between the wastewater and the purifying agent, thus achieving rapid and uniform mixing. The mixed wastewater flows into the tank 1 through the delivery pipe. The controller 3 starts the servo motor 11, which drives the transmission gear 12 to rotate. Through the driven gear 13 and the connecting shaft 14, the piston rod 15 moves up and down reciprocally. The pressure plate 16 at the bottom of the piston rod 15 moves up and down within the tank 1, pressurizing and filtering the wastewater. This allows the wastewater to undergo rapid filtration through layers such as the filter screen 20, removing tiny particles and pollutants from the wastewater.

[0034] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.

[0035] Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing public power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
