Description

A wastewater treatment device for grinding mills used in the preparation of high-magnification aluminum alloy samples Technical Field

[0001] This utility model relates to the field of aluminum alloy production technology, specifically to a wastewater treatment device for grinding mills used in the preparation of high-magnification aluminum alloy samples. Background Technology

[0002] The preparation of high-magnification aluminum alloy samples is a crucial step in material microstructure analysis and quality inspection. The preparation process typically involves multiple steps, including coarse grinding, fine grinding, coarse polishing, and fine polishing. The coarse and fine grinding stages require grinding with sandpaper on a grinding machine. To prevent sample overheating and reduce friction between the sandpaper and the sample, continuous water cooling and lubrication are necessary. This process generates a large amount of wastewater containing solid particulate impurities. Direct discharge of this wastewater not only wastes water resources but also causes serious environmental pollution due to particulate pollutants such as alumina and silicon carbide. Currently, some companies use centralized treatment methods, discharging grinding wastewater into industrial wastewater systems. However, the alumina and silicon carbide particles in the wastewater easily settle, often causing pipeline blockages during wastewater transport, significantly increasing the operation and maintenance costs and malfunction risks of industrial wastewater treatment systems. While various grinding wastewater treatment solutions exist in existing technologies, they all suffer from significant drawbacks: some methods rely on complex filtration devices and frequent filter replacements, resulting in high equipment operating costs and making them difficult for enterprises to widely adopt; furthermore, although some methods consider the treatment of resin components in the wastewater, their application in actual high-magnification aluminum alloy sample preparation is extremely low due to the high cost and low efficiency of resin. In addition, large aluminum processing enterprises, limited by the cost of automated equipment and the complexity of processes, still generally use manual grinding methods, resulting in relatively simple impurities in the grinding wastewater, mainly consisting of broken sandpaper fibers, alumina, silicon carbide, corundum, and a small amount of aluminum alloy metal particles. Most of these impurities have good settling characteristics, and the trace amounts dissolved in water do not significantly affect the cooling and lubrication functions of the circulating water in the grinding process. Therefore, developing a treatment device that is simple in structure, easy to operate, has low consumable costs, and enables wastewater recycling is of great significance for solving the environmental pollution and resource waste problems in the preparation of high-magnification aluminum alloy samples. Summary of the Invention

[0003] This invention provides a wastewater treatment device for grinding mills used in the preparation of high-magnification aluminum alloy samples, in order to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A wastewater treatment device for a grinding machine used to prepare high-magnification aluminum alloy samples includes a sedimentation tank, a water storage tank on one side of the sedimentation tank, a filter screen horizontally and detachably installed on the upper side of the sedimentation tank, a sedimentation tank inlet pipe passing through the filter screen, an inclined sedimentation platform fixed at the bottom of the sedimentation tank, with the top surface of the sedimentation platform facing the bottom end of the sedimentation tank inlet pipe, a sedimentation tank outlet pipe connected to the top side of the sedimentation tank, and the sedimentation tank outlet pipe extending into the left tank of the water storage tank, a circulation pump installed in the right tank of the water storage tank, and the circulation pump also connected to the water storage tank outlet pipe.

[0006] Furthermore, the filter screen has an inlet pipe hole, and the inlet pipe of the sedimentation tank is installed through the inlet pipe hole.

[0007] Furthermore, multiple water inlet pipe fixing rings are fixedly provided on the inner wall of the sedimentation tank, and the water inlet pipe of the sedimentation tank and the water inlet pipe fixing rings are fixedly connected.

[0008] Furthermore, a sedimentation tank outlet hole is provided on the top side of the outer side of the sedimentation tank, and the sedimentation tank outlet pipe is connected to the sedimentation tank outlet hole.

[0009] Furthermore, a drainage hole for the sedimentation tank is provided at the bottom of the sedimentation tank.

[0010] Furthermore, the water storage tank is equipped with a baffle plate, and the left tank body of the water storage tank is located on one side of the baffle plate, while the right tank body of the water storage tank is located on the other side of the baffle plate.

[0011] Furthermore, a drain hole for the water storage tank is also provided at the bottom of the right side of the water storage tank.

[0012] This utility model has the following beneficial effects:

[0013] This utility model device mainly consists of a sedimentation tank with an inclined sedimentation platform inside. A water storage tank divided into left and right sections is located outside the sedimentation tank. When treating wastewater from grinding high-magnification aluminum alloy samples, the wastewater enters the sedimentation tank through the inlet pipe and undergoes sedimentation on the sedimentation platform, achieving effective solid-liquid separation. After passing through a filter screen, the filtered wastewater then enters the left and right water storage tanks for further sedimentation and filtration, further filtering particulate impurities. Finally, the clarified filtered water is pumped out for reuse. The entire wastewater treatment process is fast and efficient, improving the overall economy of the sample grinding process. It solves the problem of low overall sample preparation efficiency caused by poor treatment effects and low economic efficiency in current methods for treating wastewater from grinding machines in the preparation of high-magnification aluminum alloy samples.

[0014] This utility model's wastewater treatment device for grinding mills used for high-magnification aluminum alloy samples has significant beneficial effects. Through targeted design, it fully utilizes the characteristic that impurities in wastewater are easy to settle, and adopts low-cost, low-complexity solid-liquid separation technology, avoiding the use of complex filtration devices and a large amount of consumables, thus greatly reducing the wastewater treatment costs for enterprises. The device has a simple structure and is easy to operate, and can efficiently separate particulate pollutants such as alumina and silicon carbide, effectively preventing pipeline blockage during wastewater treatment. At the same time, it realizes the recycling of water resources, which not only reduces water waste but also eliminates the environmental pollution hazards caused by direct discharge of wastewater. It greatly meets the dual needs of aluminum alloy processing enterprises for green production and cost reduction and efficiency improvement, and has high practicality and promotion value.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] As shown in Figure 1, a wastewater treatment device for a grinding machine used to prepare high-magnification aluminum alloy samples includes a sedimentation tank 4, a water storage tank 11 on one side of the sedimentation tank 4, a filter screen 1 horizontally and detachably installed on the upper side of the interior of the sedimentation tank 4, a sedimentation tank inlet pipe 2 passing through the filter screen 1, an inclined sedimentation platform 6 fixedly installed at the bottom of the sedimentation tank 4, and the top surface of the sedimentation platform 6 and the bottom end of the sedimentation tank inlet pipe 2 facing each other, a sedimentation tank outlet pipe 9 connected to the top side of the exterior of the sedimentation tank 4, and the sedimentation tank outlet pipe 9 extending into the left tank body 10 of the water storage tank 11, a circulation pump 16 installed in the right tank body 14 of the water storage tank 11, and the circulation pump 16 is also connected to the water storage tank outlet pipe 12.

[0020] The filter screen 1 has a water inlet hole 3, and the sedimentation tank water inlet pipe 2 is installed through the water inlet hole 3.

[0021] Multiple water inlet pipe fixing rings 5 ​​are fixedly installed on the inner wall of the sedimentation tank 4, and the sedimentation tank water inlet pipe 2 and the water inlet pipe fixing rings 5 ​​are fixedly connected.

[0022] The sedimentation tank 4 has a sedimentation tank outlet hole 8 on its outer top side, and the sedimentation tank outlet pipe 9 is connected to the sedimentation tank outlet hole 8.

[0023] The bottom of the sedimentation tank 4 is provided with a sedimentation tank drain hole 7.

[0024] The water storage tank 11 is equipped with a water baffle plate 13, and the left tank body 10 of the water storage tank is located on one side of the water baffle plate 13, while the right tank body 14 of the water storage tank is located on the other side of the water baffle plate 13.

[0025] The bottom of the right tank body 14 of the water storage tank is also provided with a water storage tank drain hole 15.

[0026] The sedimentation tank 4 of this device is mainly used for sedimentation and filtration of impurities in wastewater. The water storage tank 11 is used for secondary sedimentation and storage of water, as well as recycling. The sedimentation tank 4 is a square tank with a sedimentation tank outlet 8 designed on the upper right side of the tank. The sedimentation tank outlet 8 is connected to a sedimentation tank outlet pipe 9, which is inserted into the water storage tank 11 to allow water in the sedimentation tank 4 to overflow into the water storage tank 11. A filter screen 1 is installed below the sedimentation tank outlet 8, horizontally covering the entire sedimentation tank 4. The filter screen 1 is composed of multiple layers of gauze with a frame and is removable. It is used to filter floating objects such as sandpaper on the water surface. A water inlet pipe hole 3 is designed on the left side of the filter screen 1. The water inlet pipe hole 3 is used to insert the sedimentation tank outlet 8 into the water storage tank 11. Wastewater enters sedimentation tank 4 through sedimentation tank inlet pipe 2. A pipe fixing ring 5 is designed on the lower left side of sedimentation tank 4 to secure the pipe's insertion position. Below the fixing ring 5 is a sedimentation platform 6. The front end of sedimentation platform 6 slopes downwards at a 45° angle from the left side of the tank wall, while the rear end extends vertically downwards to the bottom of the tank. One edge of the outlet of sedimentation tank inlet pipe 2 rests against the sedimentation platform 6 below, ensuring that wastewater is close to the platform when entering the tank, preventing impurities from being stirred up. Impurities are carried downwards along the slope of sedimentation platform 6 by the water flow and settle at the bottom of the tank. A sedimentation tank drain hole 7 is designed on the lower front side of sedimentation tank 4, normally blocked, for draining water when cleaning sedimentation tank 4. The water storage tank 11 is connected to the sedimentation tank 4 via the sedimentation tank outlet pipe 9. The water storage tank 11 is larger than the sedimentation tank. A baffle plate 13 is inserted into the middle right of the water storage tank 11. The baffle plate 13 is half the height of the water storage tank, dividing the lower part of the water storage tank 11 into two tanks, left and right. The left tank 10 is larger than the right tank 14. The sedimentation tank outlet pipe 9 is inserted into the bottom of the left tank 10. After the water enters the left tank 10, it undergoes secondary sedimentation. A circulation pump 16 is installed at the bottom right side of the right tank 14. The circulation pump 16 pumps water into the water storage tank outlet pipe 12 and delivers the water to the grinder spray pipe for recycling. The presence of the baffle plate 13 also prevents the circulation pump 16 from disturbing the secondary sedimentation impurities at the bottom of the left tank 10. A water storage tank drain hole 15 is designed at the lower front side of the tank. It is normally blocked and used for draining water when cleaning the water storage tank 11.

[0027] In practical application, this invention is used in a metallographic sample pre-grinding machine for high-magnification aluminum alloy sample grinding. The machine model is GM-2. One end of the sedimentation tank inlet pipe 2 is inserted into the drain outlet of the GM-2 metallographic sample pre-grinding machine, and the other end passes through the inlet pipe hole 3 of the filter screen 1 and the inlet pipe fixing ring 5 of the sedimentation tank 4, and is inserted into the sedimentation tank 4 so that the pipe opening rests against the sedimentation platform 6. During operation, wastewater flows out from the drain outlet of the GM-2 metallographic sample pre-grinding machine, flows through the sedimentation tank inlet pipe 2, and onto the sedimentation platform 6 of the sedimentation tank 4. Because the sedimentation platform 6 is a 45° slope, the sediment slides down the sedimentation platform 6 with the water flow to the bottom of the sedimentation tank 4. There is no water flow disturbance inside the tank, and the sediment is fixed. As the wastewater volume increases, the water level in the sedimentation tank 4 slowly rises, and the upper layer of water gradually becomes clearer. Some floating debris, such as broken sandpaper, may appear on the surface. When the water level reaches the filter screen 1, the floating debris is filtered below the filter screen. The filter screen is basically clean of large particles and floating impurities on the water surface. When the water volume increases again, the sediment... The filtered water will flow out from outlet 8 of the sedimentation tank and enter the water storage tank 11. The left tank 10 of the water storage tank performs secondary sedimentation and filtration. Once the left tank 10 is full, the water will automatically flow into the right tank 14 of the water storage tank until the entire water storage tank 11 is full. When needed, the circulation pump 16 in the right tank 14 of the water storage tank will be turned on to pump the water into the spray pipe of the metallographic pre-grinding machine, achieving water recycling. Because this grinding step involves coarse and fine grinding, the presence of tiny particles in the water will not affect the grinding process. Effects; Furthermore, when it is necessary to clean the filter screen 1, simply remove the filter screen 1, remove the floating objects on the water, clean the filter screen and reinstall it; when cleaning the sediment in the sedimentation tank 4, open the sedimentation tank drain hole 7, drain the remaining water in the tank, remove the sediment at the bottom of the tank, clean the tank body, and close the sedimentation tank drain hole 7; when cleaning the water storage tank 11, pull out the baffle plate 13, open the water storage tank drain hole 15, clean the tank body, and then close the water storage tank drain hole 15.
