Description

Technical Field

[0001] This utility model relates to the field of scraper machine technology, and in particular to a scraper machine for waste material recycling in the preparation of zinc oxide. Background Technology

[0002] Zinc oxide production often uses zinc-containing waste as raw material. Direct discharge of tailings not only wastes resources but may also cause environmental pollution. Tailings return scraper is mainly used in the recycling and transportation of tailings during the zinc oxide production process. It is especially suitable for the process of preparing zinc oxide from zinc-containing waste (such as zinc-containing paint slag, zinc slag and other hazardous solid wastes).

[0003] In existing zinc oxide tailings return scraper machines, zinc oxide particles of different diameters are screened through a sieve. Qualified zinc oxide particles pass through the sieve and enter the collection vehicle, thus completing the preparation and collection of zinc oxide particles. However, due to prolonged use of the sieve, some larger zinc oxide particles or foreign objects may clog the sieve holes, affecting the screening rate and effect, which is not conducive to the normal progress of zinc oxide preparation. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: In the use of existing zinc oxide tailings return scraper machines, zinc oxide particles of different diameters are screened through a sieve. Qualified zinc oxide particles pass through the sieve and enter the collection vehicle, thus completing the preparation and collection of zinc oxide particles. However, due to prolonged use of the sieve, some larger zinc oxide particles or foreign objects can clog the sieve holes, affecting the screening rate and effect, and hindering the normal progress of zinc oxide preparation. Therefore, this invention proposes a zinc oxide tailings return scraper machine.

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

[0006] A scraper conveyor for waste material recycling in the preparation of zinc oxide includes a scraper conveyor housing and a support, wherein the support is fixedly connected to the scraper conveyor housing;

[0007] The scraper conveyor housing is equipped with a vibrating component, which includes a screening screen, a cylinder, a push rod, a fixed rod, and an impact rod. A partition is fixedly connected to the inner wall of the scraper conveyor housing. Multiple fixed rods are fixedly connected to the inner wall of the scraper conveyor housing. Multiple cylinders are fixedly connected to the inner wall of the scraper conveyor housing. The push rod is slidably connected inside the cylinder. A straight spring is fixedly connected between the push rod and the inner wall of the cylinder. The screening screen is fixedly connected between the multiple push rods. One end of the fixed rod, which passes through the screening screen, is fixedly connected to the impact rod. The fixed rod is slidably connected to the screening screen.

[0008] Preferably, the scraper conveyor housing is fixedly connected to a collection vehicle, the impact rod is U-shaped, two sliding rods are fixedly connected inside the impact rod, and a connecting block is slidably connected to the outer surface of the sliding rod.

[0009] Preferably, the connecting block passes through the impact rod and is slidably connected to the impact rod, and a brush plate is fixedly connected between the two connecting blocks, the brush plate being slidably connected to the screening screen.

[0010] Preferably, a collection box is fixedly connected to the outer surface of the screening screen, and a pull plate is fixedly connected to the outer surface of the brush plate. The pull plate passes through the outer shell of the scraper machine and is slidably connected to the outer shell of the scraper machine.

[0011] Preferably, a movable block is fixedly connected to the outer surface of the screening screen, a through hole is opened on the outer surface of the scraper conveyor housing, the movable block is slidably connected in the through hole, a rotating shaft is rotatably connected to the outer surface of the scraper conveyor housing, an eccentric wheel is fixedly connected to the outer surface of the rotating shaft, and a pressure plate is fixedly connected to one end of the movable block that passes through the through hole.

[0012] Preferably, the pressure plate is slidably connected to the outer surface of the scraper conveyor housing, the eccentric wheel is slidably connected to the pressure plate, and the outer surface of the rotating shaft is provided with a rotating handle.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the combined action of components such as the rotating shaft, straight spring, and push rod, continuous vibration is generated between the screening screen and the impact rod. This vibration is ultimately transmitted to the screening hole and acts on the zinc oxide particles or foreign objects inside the screening hole, causing them to detach from the screening hole and preventing them from clogging the screening hole. This completes the initial cleaning of the screening screen, improves the continuous use of the screening screen, increases screening efficiency, and thus improves the preparation efficiency of zinc oxide particles.

[0015] 2. Through the coordinated action of parts such as sliding rods, brush plates, and pull plates, particles or foreign objects on the screening screen are allowed to enter the collection box through the discharge port, preventing the accumulation of particles or foreign objects and the blockage of the screening holes. Workers can clean the screening screen without opening the outer casing of the scraper conveyor, improving cleaning efficiency and reducing cleaning difficulty. Attached Figure Description

[0021] 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.

[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0023] Reference Figure 1 A scraper conveyor for waste material recycling in the preparation of zinc oxide includes a scraper conveyor housing 1 and a support 2. The support 2 is fixedly connected to the scraper conveyor housing 1 and is made of steel structure, which can stably support the scraper conveyor housing 1. A discharge port is opened on the lower surface of the scraper conveyor housing 1. A collection cart 3 is fixedly connected to the scraper conveyor housing 1. The lower surface of the collection cart 3 is provided with pulleys to facilitate workers to pull the collection cart 3. At the same time, the collection cart 3 is directly facing the discharge port of the scraper conveyor housing 1.

[0024] Reference Figure 3-4 The scraper conveyor housing 1 is equipped with a vibrating component, which includes a screening screen 5, a cylinder 6, a push rod 7, a fixing rod 9, and an impact rod 10. A partition 4 is fixedly connected to the inner wall of the scraper conveyor housing 1. Multiple fixing rods 9 are fixedly connected to the inner wall of the scraper conveyor housing 1, with three fixing rods in total. Multiple cylinders 6 are fixedly connected to the inner wall of the scraper conveyor housing 1, with four cylinders in total, corresponding to the four corners of the screening screen 5. Figure 4As shown, push rod 7 is slidably connected inside cylinder 6. A straight spring 8 is fixedly connected between push rod 7 and the inner wall of cylinder 6. The straight spring 8 has a large elastic force. The elastic force of multiple straight springs 8 can make the screening screen 5 quickly reset and generate a certain impact force. The screening screen 5 is fixedly connected between multiple push rods 7. Multiple screening holes are opened on the outer surface of the screening screen 5. The screening holes are of the same size. One end of the fixing rod 9 passes through the screening screen 5 and is fixedly connected to the impact rod 10. The fixing rod 9 is slidably connected to the screening screen 5.

[0025] Reference Figure 3 The impact rod 10 is U-shaped. Two sliding rods 11 are fixedly connected inside the impact rod 10. The outer surface of the sliding rod 11 is relatively smooth. A connecting block 12 is slidably connected to the outer surface of the sliding rod 11. The connecting block 12 passes through the impact rod 10 and is slidably connected to the impact rod 10. A brush plate 13 is fixedly connected between the two connecting blocks 12. The lower end of the brush plate 13 is provided with multiple bristles. The brush plate 13 is slidably connected to the screening screen 5. A collection box 15 is fixedly connected to the outer surface of the screening screen 5. A pull plate 14 is fixedly connected to the outer surface of the brush plate 13. The pull plate 14 passes through the scraper machine housing 1 and is slidably connected to the scraper machine housing 1.

[0026] Reference Figure 1-2 A movable block 16 is fixedly connected to the outer surface of the screening screen 5. A through hole is opened on the outer surface of the scraper conveyor housing 1, and the movable block 16 is slidably connected within the through hole. A rotating shaft 18 is rotatably connected to the outer surface of the scraper conveyor housing 1. Figure 2 As shown, an eccentric wheel 19 is fixedly connected to the outer surface of the rotating shaft 18, and a pressure plate 17 is fixedly connected to one end of the moving block 16 that passes through the through hole. The pressure plate 17 is slidably connected to the outer surface of the scraper machine housing 1. The eccentric wheel 19 is slidably connected to the pressure plate 17, and a rotating handle is provided on the outer surface of the rotating shaft 18.

[0027] In this invention, when the screening screen 5 inside the scraper conveyor housing 1 needs cleaning, the rotating shaft 18 is first rotated by turning the handle. The rotation of the rotating shaft 18 drives the eccentric wheel 19 to rotate, and the rotation of the eccentric wheel 19 begins to squeeze the pressure plate 17. The movement of the pressure plate 17 causes the screening screen 5 to move downwards. The downward movement of the screening screen 5 causes the push rod 7 to squeeze the straight spring 8 inside the cylinder 6. The straight spring 8 is compressed and deformed under pressure. When the rotating shaft 18 drives the eccentric wheel 19 away from the pressure plate 17, the pressure plate 17 is no longer under pressure, and the straight spring 8 springs back to its original position. Under the action of force, the screening screen 5 is reset and impacts the impact rod 10. The impact between the screening screen 5 and the impact rod 10 generates vibration, which is transmitted to the screening screen 5. As the rotating shaft 18 continues to rotate, this vibration will continue to be generated and eventually transmitted to the position of the screening hole, acting on the zinc oxide particles or foreign objects in the screening hole, causing them to detach from the screening hole and preventing them from clogging the screening hole. This completes the initial cleaning of the screening screen 5, improves the continuous use of the screening screen 5, improves the screening efficiency, and thus improves the preparation efficiency of zinc oxide particles.

[0028] After the sieving holes are cleared, to prevent larger diameter zinc oxide particles or foreign objects from continuing to clog them, they need to be collected and cleaned promptly. By pulling the brush plate 14, the brush bristles on the brush plate 13 will move the zinc oxide particles or foreign objects to one end of the sieving screen 5. Since there is a discharge port between the collection box 15 and the sieving screen 5, these particles or foreign objects enter the collection box 15 through the discharge port, ensuring the surface of the sieving screen 5 is clean and preventing the accumulation of particles or foreign objects that could clog the sieving holes. Workers can clean the sieving screen 5 without opening the scraper machine housing 1, improving cleaning efficiency and reducing cleaning difficulty. At the same time, the vibration generated by the sieving screen 5 will also act on the brush plate 13, shaking off the particles or foreign objects on the brush plate 13, improving the continuous working capacity of the brush plate 13.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0030] 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.
