Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically a zinc oxide tailings filter press with an automatic slag discharge mechanism. Background Technology

[0002] The industrial production process of zinc oxide, such as the direct method, uses impure zinc-containing compounds such as calamine or byproducts of zinc refining as raw materials. These compounds are heated with carbon to reduce zinc vapor, which is then oxidized to zinc oxide. This process generates a large amount of tailings. Hot-dip galvanizing plants and electrolytic zinc plants also produce tailings containing zinc oxide, such as zinc ash and zinc slag, during the production process. The main components are zinc oxide, metallic zinc, and some impurities.

[0003] The core purpose of zinc oxide tailings filtration is to achieve solid-liquid separation through mechanical pressure, reduce the moisture content of the tailings, create conditions for subsequent treatment, transportation and resource utilization, and reduce the risk of environmental pollution. Filtration is usually carried out using a filter press. During the filtration process, zinc oxide tailings will physically adhere to the filter press frame. Washing will allow the tailings to re-blend with water. While manual tapping can effectively reduce tailings adhesion, it is labor-intensive and poses operational safety issues. Therefore, secondary technical improvements have been made to the existing filter press technology to enable it to smoothly remove most of the adhered tailings. Summary of the Invention

[0004] The purpose of this invention is to provide a zinc oxide tailings filter press with an automatic slag discharge mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A zinc oxide tailings filter press with an automatic slag discharge mechanism includes a frame, a main unit, a pressing device, a frame plate, and a pulling plate mechanism. The frame is equipped with a pressing device, and a movable pulling plate mechanism is installed on the crossbeam of the frame via a slide rail. A frame plate is installed on the crossbeam, and handles are installed on both sides of the frame plate. A rail for supporting the horizontal movement of the handles is provided on the crossbeam, and an assembly groove is opened inside the rail. A slag shaking mechanism is installed in the assembly groove. The slag-removing mechanism includes a crank arm, a linkage shaft, and an electric push rod. The crank arm is rotatably installed in the mounting slot of the track. The bottom end of the crank arm is rotatably connected through the linkage shaft, which is rotatably connected to the telescopic end of the electric push rod. The electric push rod is rotatably connected to the crossbeam through bearing a.

[0006] As a further embodiment of this utility model: the handle includes a mounting base, a bracket, a grooved wheel, and a support arm. The handle is installed on the frame plate by bolts. The mounting base is fixed to the bracket. A grooved wheel that can roll on a track is rotatably installed on the bracket. A support arm with increased height and located above the pull plate mechanism is provided on the other side of the bracket.

[0007] As a further improvement of this utility model: the groove depth of the groove wheel is greater than the height of the protrusion from the track after the crank arm rotates, the height of the track is adapted to the groove depth of the groove wheel, and anti-detachment extension plates are installed on the bracket on both sides below the groove wheel.

[0008] As a further embodiment of this utility model: the curved arm is rotatably connected to the track via bearing b, and the curved arm rotates with bearing b as the fulcrum. The curved arm is rotatably connected to the linkage shaft via bearing c. When the linkage shaft drives the curved arm to rotate clockwise with bearing b as the fulcrum, the top of the curved arm extends out of the track to form a protruding part. When the linkage shaft drives the curved arm to rotate counterclockwise with bearing b as the fulcrum, the top of the curved arm retracts back into the track.

[0009] As a further improvement of this utility model: the plate pulling mechanism comprises a movable box, a hydraulic cylinder and a limiting end, wherein the limiting end is installed in the movable box through the hydraulic cylinder, and there are two sets of limiting ends installed in the hydraulic cylinder.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This zinc oxide tailings filter press with an automatic slag discharge mechanism adds a slag shaking mechanism to the existing technology. It utilizes the positioning function of the main unit and the plate pulling mechanism to control the slag shaking mechanism to perform the operation of the frame plate transfer and replacement. During the process of the plate pulling mechanism dragging the frame plate, the tailings are shaken off by the slag shaking mechanism, thereby realizing the function of automatic slag discharge.

[0013] Please see Figures 1-5 In this embodiment of the present invention, a zinc oxide tailings filter press with an automatic slag discharge mechanism includes a frame 1, a main unit 3, a pressing device 4, a frame plate 5, and a pulling plate mechanism 7. The frame 1 is equipped with the pressing device 4. A movable pulling plate mechanism 7 is installed on the crossbeam 2 of the frame 1 via a slide rail 11. The crossbeam 2 is equipped with a frame plate 5. Handles 6 are installed on both sides of the frame plate 5. The crossbeam 2 is provided with a track 9 for supporting the horizontal movement of the handles 6. An assembly groove 10 is opened inside the track 9. A slag shaking mechanism is installed in the assembly groove 10. The slag-shaking mechanism includes a curved arm 12, a linkage shaft 8, and an electric push rod 15. The curved arm 12 is rotatably installed in the assembly slot 10 of the track 9. The bottom end of the curved arm 12 is rotatably connected to the linkage shaft 8, which is rotatably connected to the telescopic end of the electric push rod 15. The electric push rod 15 is rotatably connected to the crossbeam 2 through the bearing a16. During normal operation, the handle 6 slides smoothly on the track 9. When the pulling plate mechanism 7 separates the frame plates 5 for sequential slag discharge, the electric push rod 15 pushes the linkage shaft 8 to rotate the curved arm 12. The rotating part of the curved arm 12 protrudes. When the pulling plate mechanism 7 moves the frame plate 5 past the protruding curved arm 12, it will experience a process of being lifted and then falling. During this process, the impact force of the frame plate 5 falling will shake off the tail slag. Since there are many frame plates, when most of them have been moved to the head, the remaining frame plate movement cannot pass through the slag-shaking mechanism. Therefore, multiple slag-shaking mechanisms are set in the crossbeam 2, and the operation is controlled by the main unit 3.

[0014] In a preferred embodiment, the handle 6 includes a mounting base 601, a bracket 602, a grooved wheel 603, and a support arm 604. The handle 6 is bolted to the frame plate 5. The mounting base 601 is fixed to the bracket 602. The grooved wheel 603, which can roll on the track 9, is rotatably mounted on the bracket 602. The other side of the bracket 602 is provided with a support arm 604, which is heightened and located above the pull plate mechanism 7. The groove depth of the grooved wheel 603 is greater than the height of the curved arm 12 protruding from the track 9 after rotation. The height of the track 9 is adapted to the groove depth of the grooved wheel 603. Anti-derailment extension plates 605 are installed on both sides below the grooved wheel 603 on the bracket 602. When the frame plate performs the slag shaking action, the conventional grooved wheel 603 may derail during the fall of the curved arm 12. To avoid this phenomenon, the depth of the grooved wheel 603 and the height of the track 9 are increased to ensure safe operation. At the same time, the anti-derailment extension plates 605 are configured to prevent derailment.

[0015] In a preferred embodiment, the crank arm 12 is rotatably connected to the track 9 via bearing b13. The crank arm 12 rotates around bearing b13 as a fulcrum. The crank arm 12 is rotatably connected to the linkage shaft 8 via bearing c14. When the linkage shaft 8 drives the crank arm 12 to rotate clockwise around bearing b13, the top of the crank arm 12 extends out of the track 9 to form a protruding part. When the linkage shaft 8 drives the crank arm 12 to rotate counterclockwise around bearing b13, the top of the crank arm 12 retracts back to the track 9. The crank arm 12 changes the horizontal height of the frame plate during movement by rotating, thereby achieving slag removal. The electric push rod 15 is electrically connected to the host 3, and the host 3 controls the retraction of the electric push rod 15.

[0016] In a preferred embodiment, the plate-pulling mechanism 7 comprises a movable housing 701, a hydraulic cylinder 702, and a limiting end 703. The limiting end 703 is installed inside the movable housing 701 via the hydraulic cylinder 702. There are two sets of hydraulic cylinders 702 with limiting ends 703 installed. The plate-pulling mechanism 7 is existing technology. This application uses a hydraulic plate-pulling mechanism, which is controlled and positioned by a proximity switch, encoder, and hydraulic valve. The stroke positioning of the plate-pulling mechanism 7 controls the extension and retraction of the electric push rods 15 of multiple slag-shaking mechanisms. The slag-shaking mechanisms located near the beginning and end of the stroke of the frame plate 5 are not activated to avoid damage to the slag-shaking mechanisms due to prolonged pressure from the gravity of the frame plate 5. The slag-shaking mechanisms in the middle of the frame plate 5's movement stroke are pushed up for operation. As the frame plate 5 moves, the slag-shaking mechanisms are replaced.

[0017] It should be noted that all the above embodiments belong to the same utility model concept, and the descriptions of each embodiment have different focuses. Where the description in a particular embodiment is not detailed, please refer to the description in other embodiments.

[0018] The above embodiments merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
