Description

Technical Field

[0001] This application relates to the field of precious metal recycling technology, for example to a solid-liquid separation device for precious metal recycling. Background Technology

[0002] Precious metals are being used more and more widely in traditional industries and modern high-tech industries. In modern electronics industries such as electronics, communication, aerospace, chemical, medical, automotive exhaust purification, and fiberglass, more and more electronic components can use precious metals as raw materials. They play a unique role, especially in the fields of electronics, new energy and environmental protection. Although the amount used is small, it plays an irreplaceable key role and is known as the "vitamin of industry".

[0003] However, precious metals are relatively rare, with limited reserves on Earth. They cannot be artificially synthesized, and their mining is costly and difficult. Therefore, precious metal recycling has become a key way to save energy.

[0004] Currently, hydrometallurgical recovery of precious metals (such as gold, silver, and platinum group metals) requires steps such as acid / alkali leaching, solid-liquid separation, and electrolytic deposition. Among these steps, solid-liquid separation is the key process, directly affecting the recovery rate and operating costs of precious metals.

[0005] For example, the patent technology with application number 202323136289.3, entitled "A Solid-Liquid Separation Device for Precious Metal Recycling", is a solid-liquid separation device for precious metal recycling. The device is equipped with three layers of screen plates, and the diameter of the screen holes in the three layers of screen plates decreases from top to bottom, making the filtration more fine and allowing fine solid particles to be filtered out. At the same time as filtration, the transmission component drives the screen plates to move back and forth, increasing the rolling speed of solid particles on the screen plates and preventing solid particles from accumulating on the screen plates.

[0006] However, the device requires disassembling the entire unit to clean the filter screen, which is cumbersome and inefficient. While the reciprocating movement of the sieve plate can prevent solid particles from accumulating on the sieve plate, precious metals are very likely to fly out of the collection box due to inertia during the reciprocating movement, affecting the collection effect.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

[0030] Currently, hydrometallurgical recovery of precious metals (such as gold, silver, and platinum group metals) requires steps such as acid / alkali leaching, solid-liquid separation, and electrolytic deposition. Among these steps, solid-liquid separation is the key process, directly affecting the recovery rate and operating costs of precious metals.

[0031] For example, the patent technology with application number 202323136289.3, entitled "A Solid-Liquid Separation Device for Precious Metal Recycling", is a solid-liquid separation device for precious metal recycling. The device is equipped with three layers of screen plates, and the diameter of the screen holes in the three layers of screen plates decreases from top to bottom, making the filtration more fine and allowing fine solid particles to be filtered out. At the same time as filtration, the transmission component drives the screen plates to move back and forth, increasing the rolling speed of solid particles on the screen plates and preventing solid particles from accumulating on the screen plates.

[0032] However, the device requires disassembling the entire unit to clean the filter screen, which is cumbersome and inefficient. While the reciprocating movement of the sieve plate can prevent solid particles from accumulating on the sieve plate, precious metals are very likely to fly out of the collection box due to inertia during the reciprocating movement, affecting the collection effect.

[0033] Therefore, the design concept of this application is to redesign the filter screen so that the entire device can be cleaned without disassembling it, which saves more time and effort.

[0034] like Figure 1 As shown, this application provides a solid-liquid separation device for precious metal recycling, including a separation box 1 with an upper opening. An inclined filter screen 2 is installed inside the separation box 1. A collection port 3 is connected to the lower left side of the inclined filter screen 2, and a collection box 4 is installed at the collection port 3. A lifting plate is connected to the upper right side of the inclined filter screen 2, and the lifting plate is connected to a lifting mechanism. A liquid collection tank 5 is connected to the bottom of the separation box 1. The bottom of the separation box 1 adopts a funnel-shaped liquid collection trough 101, with a discharge port at the bottom. A liquid collection tank inlet 501 is opened at the top of the liquid collection tank 5. The area of ​​the liquid collection tank inlet 501 is larger than the discharge port at the bottom of the liquid collection trough 101. This design facilitates the downward flow of liquid from the liquid collection trough 101 to the liquid collection tank 5 during vibration of the separation box 1, avoiding splashing.

[0035] The inclined filter screen 2 has at least two layers; the multi-layer design is more conducive to screening out solid particles of different sizes; each layer of inclined filter screen 2 corresponds to a collection port 3 and a collection box 4.

[0036] The collection port 3 is located on the left side wall of the separation box 1. When in use, solid particles that do not pass through the mesh of the inclined filter screen 2 will move towards the lower left side along the inclined filter screen 2 and eventually fall into the collection box 4.

[0037] The inclined filter screen 2 is connected to a mounting base 6 on its right side, and the mounting base 6 is threadedly connected to the lifting plate. In use, each layer of inclined filter screen 2 can be disassembled and assembled by connecting bolts, which is convenient for cleaning and replacing the inclined filter screen 2.

[0038] The lifting plate includes a vertical plate 7 threadedly connected to the mounting base 6 and a 7-shaped plate 8 connected to the vertical plate 7. The 7-shaped plate 8 is connected to the lifting mechanism. The lifting mechanism is a ball screw slide 9, and the nut seat of the ball screw slide 9 is connected to the 7-shaped plate 8.

[0039] When in use, start the ball screw slide 9 to raise and lower the 7-shaped plate 8, which in turn raises and lowers the inclined filter screen 2, making it easy for later maintenance, cleaning and replacement.

[0040] The bottom of the collection tank 5 is connected to a drain valve 10; when in use, the drain valve 10 is connected to an output pump to discharge the waste liquid inside the collection tank 5.

[0041] The bottom of the separation box 1 is provided with a vibration motor 11 and an elastic base. The elastic base includes an upper connecting block 12 connected to the bottom of the separation box 1, a spring 13 connected to the upper connecting block 12, and a lower connecting block 14 connected to the spring 13. The lower connecting block 14 is connected to the liquid collection tank 5.

[0042] When in use, start the vibration motor 11 to vibrate the separation box 1, thereby assisting in material screening and better preventing material from accumulating on the inclined filter screen 2.

[0043] In this application, a mixture of precious metal solid and liquid enters and falls onto the inclined filter screen 2. Under the action of its own gravity, the precious metal solid particles pass through the collection port 3 and fall obliquely into the collection box 4. When the precious metal solid particles accumulate on the inclined filter screen 2, the vibration motor 11 can be turned on to vibrate the separation box 1.

[0044] This application designs the inclined filter screen 2 as a lifting type, so that the entire equipment does not need to be disassembled, and the filter screen can be cleaned, which saves more time and effort. Moreover, the vibration motor 11 is used to vibrate the separation box 1 to avoid the accumulation of materials on the inclined filter screen 2, avoiding the drawback of the precious metal flying out of the collection box due to inertia and affecting the collection effect in the solid-liquid separation device patent technology for precious metal recycling in application number 202323136289.3.
