Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater separation and recovery device for precious metal recovery. Background Technology

[0002] Precious metals are present in grinding wastewater in the semiconductor industry, requiring separation and recovery. Currently, centrifuges are generally used for solid-liquid separation of materials. In existing technology, centrifuges typically operate by using a motor spindle to drive the internal filter cartridges to rotate at high speed, thereby centrifuging the materials. However, due to the strong centrifugal force, the separated metal sludge particles tend to adhere to the inner wall of the filter cartridges, making them difficult to remove and prone to clogging the filter pores, affecting filtration efficiency. In severe cases, it can even lead to filter cartridge blockage and prevent normal filtration and separation, presenting certain drawbacks. Utility Model Content

[0003] The purpose of this invention is to provide a wastewater separation and recovery device for precious metal recycling, which can efficiently separate and discharge precious metals in wastewater for recovery, effectively preventing the problem of filter cartridge clogging.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A wastewater separation and recovery device for precious metal recycling is provided, comprising: a main housing, a filter cartridge, a motor, and a scraper. The filter cartridge is vertically rotatably connected to the main housing and driven by the motor. The side wall of the filter cartridge has evenly distributed filter holes, and the top of the filter cartridge has an open structure. The scraper is vertically arranged below the upper wall of the main housing and is in close contact with the inner wall of the filter cartridge. A discharge pipe is arranged below the middle of the filter cartridge, and the lower end of the discharge pipe extends out of the main housing. A drain pipe for drainage is arranged at the bottom side of the main housing, and a feed inlet is arranged at the top of the main housing.

[0021] Reference Figures 1-2This utility model provides a wastewater separation and recovery device for precious metal recycling, characterized in that it includes: a main housing 1, a filter cylinder 2, a motor 3, and a scraper 4. The filter cylinder 2 is vertically rotatably connected to the main housing 1 and driven by the motor 3. The side wall of the filter cylinder 2 is evenly distributed with filter holes. The top of the filter cylinder 2 is an open structure. The scraper 4 is vertically arranged below the upper wall of the main housing 1. The scraper 4 is in close contact with the inner wall of the filter cylinder 2. A discharge pipe 5 is arranged below the middle of the filter cylinder 2. The lower end of the discharge pipe 5 extends out of the main housing 1. A drain pipe 6 for drainage is arranged at the bottom side of the main housing 1. A feed inlet 7 is arranged at the top of the main housing 1.

[0022] In the above technical solution, a scraper 4 is installed inside the main housing 1, closely attached to the inner wall of the filter cylinder 2, and a discharge pipe 5 is installed at the lower middle of the filter cylinder 2, extending out of the main housing 1. A drain pipe 6 is installed at the bottom side of the main housing 1. When wastewater separation and recycling are performed, wastewater is poured into the filter cylinder 2 from the inlet 7 of the main housing 1. The motor 3 drives the filter cylinder 2 to rotate, centrifugally filtering and separating the wastewater. Metal sludge particles in the wastewater are filtered and retained in the filter cylinder 2, while the remaining wastewater is centrifugally ejected from the filter holes into the main housing 1 and discharged from the drain pipe 6. During the centrifugal filtration and separation process of the filter cylinder 2, the scraper 4 scrapes off the metal sludge particles attached to the inner wall of the filter cylinder 2, preventing blockage of the filter holes. After the centrifugal filtration and separation is completed, the discharge pipe 5 is opened, and the filtered metal sludge particles can be smoothly discharged from the filter cylinder 2 for recycling. This achieves the function of efficiently separating and discharging precious metals in wastewater for recycling, and effectively prevents the filter cylinder 2 from clogging.

[0023] In some embodiments, a fixing ring 8 is fixed to the upper part of the main housing 1, and the upper outer periphery of the filter cartridge 2 is rotatably connected to the fixing ring 8 via a bearing. This structural design allows the filter cartridge 2 to rotate centrifugally stably and smoothly.

[0024] Furthermore, a raised truncated cone is provided at the bottom of the main housing 1, and the bottom of the filter cartridge 2 is rotatably connected to the top of the truncated cone via a bearing. This structural design not only ensures that the filter cartridge 2 can rotate stably and smoothly during centrifugal rotation, but also allows the wastewater ejected by centrifugation to flow smoothly to the outer periphery of the main housing 1 and be discharged from the drain pipe 6, reducing or preventing wastewater from seeping or leaking from the connection between the filter cartridge 2 and the main housing 1.

[0025] In some embodiments, a transmission chamber 9 is provided below the main housing 1, and the lower end of the discharge pipe 5 passes through the transmission chamber 9. A driven gear 10 is fixed to the outer periphery of the discharge pipe 5, and the driven gear 10 is located inside the transmission chamber 9. A driving gear 11 driven by the motor 3 is provided inside the transmission chamber 9, and the driving gear 11 meshes with the driven gear 10. The motor 3 drives the filter cartridge 2 to rotate through the meshing structure of the driving gear 11 and the driven gear 10, which has a simple structure and stable operation.

[0026] In some embodiments, a vertical fixing rod 12 is fixed to the lower part of the upper wall of the main housing 1. Multiple horizontal connecting rods 13 are distributed sequentially from top to bottom on one side of the fixing rod 12. The scraper 4 is fixedly connected to the ends of the multiple connecting rods 13 away from the fixing rod 12. This structural design allows the scraper 4 to be firmly and tightly attached to the inner wall of the filter cartridge 2. In other embodiments, a vertical fixing rod 12 is fixed to the lower part of the upper wall of the main housing 1. Multiple horizontal elastic telescopic rods are distributed sequentially from top to bottom on one side of the fixing rod 12. The scraper 4 is hinged to the ends of the multiple elastic telescopic rods away from the fixing rod 12, and the hinged axis is horizontal. This elastic telescopic rod connection structure ensures that even when the filter cartridge 2 shakes during rotation, the scraper 4 remains firmly attached to the inner wall of the filter cartridge 2.

[0027] In some embodiments, the bottom of the main housing 1 is provided with support feet 14.

[0028] In some embodiments, a cover plate 15 is rotatably connected to one side of the feed inlet 7, and a handle is provided on the top of the cover plate 15.
