Description

Technical Field

[0001] This utility model relates to the technical field of indium-containing waste treatment and resource recycling equipment, and in particular to a high-efficiency collection device for filter residue after acid leaching and pressure filtration of indium-containing waste. Background Technology

[0002] After acid leaching, indium-containing waste can be separated into solid and liquid phases by pressure filtration. The resulting filter residue contains not only unreacted impurities but may also contain some valuable metals. If this filter residue is not effectively collected, it will not only waste resources but also potentially pollute the environment with its harmful substances. Therefore, efficient collection of the filter residue is essential.

[0003] In existing technologies, filter residue collection devices used for pressure filtration of indium-containing waste after acid leaching often lack effective auxiliary cleaning mechanisms for their filter components. Filter residue easily clogs the mesh of the filter components, and residual filter residue on the surface of the filter components is difficult to remove, thus affecting the ventilation and filter residue collection efficiency of the device, and increasing the cost and difficulty of manual cleaning. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency collection device for filter residue after acid leaching and pressure filtration of indium-containing waste.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency collection device for filter residue from indium-containing waste after acid leaching and pressure filtration includes a collection pipe with an installation frame via a discharge port. The collection pipe contains a movable groove and a rotating groove. A sliding rod is located within the movable groove, and a sliding plate is slidably mounted on the sliding rod via an elastic mechanism. A filter screen is fixedly mounted between the two sliding plates. Two collection grooves are located on the filter screen. A first motor and a second motor are fixedly mounted on the outer wall of the collection pipe. A rotating shaft connected to the first motor is rotatably mounted within the collection pipe, and the rotating shaft is connected to the filter screen via a contact mechanism. A reciprocating screw connected to the second motor is rotatably mounted within the rotating groove. A movable frame is threadedly mounted on the reciprocating screw via a limiting mechanism. The movable frame has a connecting groove, and a connecting rod is located within the connecting groove via a connecting mechanism. A scraper is fixedly mounted on the connecting rod.

[0007] Preferably, the elastic mechanism includes a first spring sleeved on the outside of the slide bar, with both ends of the first spring connected to the inner wall of the movable groove and the outer wall of the slide plate, respectively.

[0008] Preferably, the contact mechanism includes a cam fixedly mounted on a rotating shaft, and the bottom of the filter screen is provided with an arc-shaped block corresponding to the cam.

[0009] Preferably, the limiting mechanism includes a limiting rod fixedly disposed in the rotating groove, and the limiting rod slides through the movable frame.

[0010] Preferably, the connecting mechanism includes a second spring disposed in the connecting groove, with both ends of the second spring connected to the inner wall of the connecting groove and the outer wall of the connecting rod, respectively.

[0011] Preferably, baffles are fixedly provided on both the upper and lower end faces of the filter screen, and the baffles are in sealed sliding contact with the collection pipe.

[0012] The beneficial effects of this utility model are:

[0013] 1. The filter screen moves up and down reciprocally under the action of the cam and the first spring, which can shake off the blockage in the mesh. At the same time, the scraper moves back and forth driven by components such as the reciprocating screw, pushing the filter residue remaining on the surface of the filter screen to the collection tank. This realizes the simultaneous operation of filtration, shaking off blockage and scraping off residue, which greatly improves the efficiency of filter residue collection.

[0014] 2. The cam and the first spring work together to make the filter screen vibrate by moving up and down, which can promptly remove the blockage in the mesh, prevent the filter screen from being affected by blockage, and extend the service life of the filter screen.

[0015] 3. The second spring in the connecting mechanism ensures that the scraper always stays in contact with the surface of the filter screen during the lifting and lowering process, ensuring the thorough removal of residues and reducing the residue of filter cake on the surface of the filter screen.

[0016] 4. The baffle always blocks the moving slot to prevent materials from entering the moving slot and affecting the movement of components such as the slide plate; the rotating slot is set at an angle downward to prevent objects from entering and affecting components such as the reciprocating screw, thus ensuring the stable operation of the internal structure of the device.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5 A high-efficiency collection device for filter residue from indium-containing waste after acid leaching and pressure filtration includes a collection pipe 1. A mounting frame 3 is provided on the collection pipe 1 via a discharge port 2. The collection pipe 1 contains a movable groove 12 and a rotating groove 22. A sliding rod 13 is provided in the movable groove 12. A sliding plate 21 is slidably mounted on the sliding rod 13 via an elastic mechanism. A filter screen 6 is fixedly mounted between the two sliding plates 21. Two collection grooves 7 are provided on the filter screen 6. A first motor 4 and a second motor 5 are fixedly mounted on the outer wall of the collection pipe 1. A rotating shaft 8 connected to the first motor 4 is rotatably mounted inside the collection pipe 1. The rotating shaft 8 is connected to the filter screen 6 via a contact mechanism. A reciprocating screw 15 connected to the second motor 5 is rotatably mounted inside the rotating groove 22. A movable frame 17 is threadedly mounted on the reciprocating screw 15 via a limiting mechanism. The movable frame 17 has a connecting groove 18. A connecting rod 19 is provided in the connecting groove 18 via a connecting mechanism. A scraper 11 is fixedly mounted on the connecting rod 19.

[0025] The elastic mechanism includes a first spring 14 sleeved on the outside of the slide bar 13, with both ends of the first spring 14 connected to the inner wall of the movable groove 12 and the outer wall of the slide plate 21, respectively. The elastic potential energy provided by the first spring 14 enables the slide plate 21 to be pressed down and reset.

[0026] The contact mechanism includes a cam 9 fixedly mounted on the rotating shaft 8, and an arc-shaped block corresponding to the cam 9 is provided at the bottom of the filter screen 6. The cam 9, in conjunction with the arc-shaped block, enables the filter screen 6 to reciprocate upwards.

[0027] The limiting mechanism includes a limiting rod 16 fixedly installed in the rotating groove 22, which slides through the movable frame 17. The limiting rod 16 limits the movable frame 17, preventing it from rotating with the reciprocating screw 15.

[0028] As shown in the figure, the movable frame 17 is equivalent to an irregularly shaped lead screw sleeve, and the rotating groove 22 is set at an angle downwards to effectively prevent objects from entering and affecting components such as the reciprocating lead screw 15.

[0029] The connecting mechanism includes a second spring 20 disposed within the connecting groove 18, with both ends of the second spring 20 connected to the inner wall of the connecting groove 18 and the outer wall of the connecting rod 19, respectively. The elastic potential energy provided by the second spring 20 ensures that the connecting rod 19 can move vertically relative to the movable frame 17. When the filter screen 6 is raised or lowered, the scraper 11 is raised or lowered synchronously and always in contact with the surface of the filter screen 6.

[0030] Both the upper and lower ends of the filter screen 6 are fixedly equipped with baffles 10, which are in sealed sliding contact with the collection pipe 1. The baffles 10 always block the movable groove 12 to prevent material from entering.

[0031] When this utility model is used, the filter residue produced by pressure filtration after acid leaching of indium-containing waste enters the collection pipe 1 vertically and first passes through the filter screen 6. The filter screen 6 filters the filter residue, and larger filter residues are intercepted on the surface of the filter screen 6, while some small filter residues may be embedded in the mesh.

[0032] The first motor 4 starts, driving the rotating shaft 8 to rotate. The cam 9 on the rotating shaft 8 rotates accordingly. When the protruding part of the cam 9 contacts the arc-shaped block at the bottom of the filter screen 6, it pushes the filter screen 6 to move upward. At this time, the slide plate 21 slides along the slide rod 13 in the movable groove 12, and the first spring 14 is compressed. When the protruding part of the cam 9 disengages from the arc-shaped block, under the action of the elastic potential energy of the first spring 14, the slide plate 21 drives the filter screen 6 to descend and reset. This process is repeated to realize the up-and-down reciprocating motion of the filter screen 6, using vibration to shake off the blockage embedded in the mesh.

[0033] Simultaneously, the second motor 5 starts, driving the reciprocating screw 15 to rotate within the rotating groove 22. Due to the limiting effect of the limiting rod 16 on the moving frame 17, the moving frame 17 does not rotate with the reciprocating screw 15, but instead performs reciprocating linear motion along the reciprocating screw 15 and the limiting rod 16. When the moving frame 17 moves, it drives the scraper 11 to move back and forth on the surface of the filter screen 6 through the connecting rod 19. During the up-and-down reciprocating motion of the filter screen 6, the second spring 20 in the connecting mechanism provides elastic potential energy, allowing the connecting rod 19 to move vertically relative to the moving frame 17, ensuring that the scraper 11 always adheres to the surface of the filter screen 6, pushing the filter residue remaining on the surface of the filter screen 6 into the collection groove 7.

[0034] Throughout the process, the baffle 10 and the collecting pipe 1 are in sealed sliding contact, always blocking the movable groove 12 to prevent materials from entering the movable groove 12 and affecting the movement of components such as the slide plate 21; the rotating groove 22 is set at an angle downwards to effectively prevent objects from entering and affecting the normal operation of components such as the reciprocating screw 15.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
