Description

Technical Field

[0001] This utility model relates to the field of filter cloth cleaning technology, and in particular to a gypsum cleaning device for a dewatering machine and a dewatering machine. Background Technology

[0002] In the field of gypsum dewatering, traditional dewatering machine scraper devices mainly use angle steel and polyester board connected by bolts. The distance between the scraper and the filter cloth is adjusted manually to determine the device. Although this can roughly meet the basic dewatering requirements, it has many significant drawbacks.

[0003] Because the scraper is bolted to the angle steel, it cannot automatically adjust the distance between itself and the filter cloth, resulting in uneven pressure distribution. A large amount of gypsum residue moves with the filter cloth and is difficult to remove, returning to the desulfurization system and causing filter cloth blockage. This reduces the filter cloth's air permeability and significantly decreases the vacuum level, severely impacting dewatering efficiency and quality. Additional cleaning of residual gypsum is required, consuming significant water resources and increasing labor costs. If rinsing is not timely, the filter cloth will suffer severe wear, further shortening its lifespan and creating a vicious cycle. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a gypsum cleaning device and a dehydrator to solve the above-mentioned technical problem.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A gypsum cleaning device for a dewatering machine includes: a scraper, a crossbeam, a fixed side plate, a main beam, and turnbuckles; the scraper is fixedly connected to the crossbeam, the crossbeam is rotatably mounted in the fixed side plate, and the fixed side plate is fixedly connected to the main beam; swing arms are fixedly connected to both ends of the crossbeam, a chain is fixedly connected to each swing arm, a torsion spring is connected to each chain through the turnbuckles, and each torsion spring is mounted on the main beam; a conveyor roller is rotatably mounted on the main beam, and a filter cloth is provided on the conveyor roller; the torsion springs indirectly apply an elastic force to the crossbeam to rotate it until the scraper and the filter cloth are in contact.

[0006] The beneficial effects of this invention are as follows: When the filter cloth passes between the scraper and the conveyor roller, the filter cloth and the solid plaster on it lift the scraper at a certain angle. Then, under the combined action of the swing arm, chain, and turnbuckle, the torsion spring rotates. Because the torsion spring stores energy, it generates a rotational force opposite to the direction of rotation. This rotational force is transmitted to the crossbeam via the turnbuckle, chain, and swing arm, allowing the scraper to adhere tightly to the filter cloth, thus achieving automatic adjustment of the distance between the scraper and the filter cloth. This device can precisely control the angle and pressure of the scraper, ensuring that the solid plaster separates smoothly from the surface of the filter cloth, effectively preventing damage to the filter cloth due to excessive local pressure, and guaranteeing the integrity and service life of the filter cloth.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, mounting plates are rotatably connected to both ends of the conveyor roller, and the mounting plates are fixedly connected to the main beam.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the connection between the conveyor roller and the main beam is realized through the mounting plate.

[0010] Furthermore, the device also includes a baffle and a spring. The baffle is fixedly connected to the conveyor roller, and the spring is fitted onto the conveyor roller and disposed between the baffle and the mounting plate.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, during operation, the vibration of the spring can effectively remove the solid plaster adhering to the connection between the conveyor roller and the mounting plate.

[0012] Furthermore, the device also includes a fixing plate, which is fixedly connected to the crossbeam and the scraper respectively.

[0013] The beneficial effect of adopting the above-mentioned further solution is that a stable connection between the crossbeam and the scraper is achieved through the fixing plate.

[0014] Furthermore, two fixed side plates are provided, and the two fixed side plates are respectively provided on both sides of the crossbeam.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by setting two fixed side plates, a stable connection between the crossbeam and the main beam can be achieved.

[0016] Furthermore, the device also includes a bearing, and the crossbeam is rotatably connected to the fixed side plate via the bearing.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the rotational connection between the crossbeam and the fixed side plate is achieved through bearings.

[0018] Furthermore, the device also includes a spring fixing plate, on which the torsion spring is mounted, and the spring fixing plate is fixedly connected to the main beam.

[0019] The advantage of adopting the above-mentioned further solution is that the torsion spring can be installed through the spring fixing plate.

[0020] Furthermore, the spring fixing plate includes a base plate, a mounting shaft, and an end plate. The base plate is fixedly connected to the main beam. One end of the mounting shaft is fixedly connected to the base plate. The torsion spring is fitted onto the mounting shaft. The other end of the mounting shaft is fixedly connected to one end of the end plate. A side plate is fixedly connected to the other end of the end plate. The side plate is arranged parallel to the mounting shaft. One end of the torsion spring abuts against the side plate. The other end of the torsion spring is fixedly connected to the turnbuckle.

[0021] The beneficial effects of adopting the above-mentioned further solution are as follows: by setting an installation shaft, the torsion spring can rotate around the installation shaft as the center, and an end plate is set to limit the torsion spring; one end of the torsion spring is fixedly connected to the turnbuckle, and the other end abuts against the side plate. When the turnbuckle applies tension to the torsion spring, the torsion spring rotates and stores energy. When the tension disappears, the energy is released to generate rotational force, thereby achieving rotational reset.

[0022] Furthermore, the device also includes mounting bolts, and the fixed side plate is fixedly connected to the main beam by the mounting bolts, with anti-corrosion plugs installed at the ends of the mounting bolts.

[0023] The beneficial effects of adopting the above-mentioned further solution are: the connection between the fixed side plate and the main beam is achieved by installing bolts, and anti-corrosion plugs are installed at the ends of the bolts to protect them.

[0024] To solve the above-mentioned technical problems, this utility model also proposes a dehydrator, including a gypsum cleaning device for a dehydrator as described above. Attached Figure Description

[0028] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] Example 1

[0030] like Figure 1As shown, this embodiment provides a gypsum cleaning device for a dehydrator, including: a scraper 1, a crossbeam 2, a fixed side plate 3, a main beam, and turnbuckles 4; the scraper 1 is fixedly connected to the crossbeam 2, the crossbeam 2 is rotatably mounted in the fixed side plate 3, and the fixed side plate 3 is fixedly connected to the main beam; swing arms 5 are fixedly connected to both ends of the crossbeam 2, a chain 6 is fixedly connected to each swing arm 5, and a torsion spring 7 is connected to each chain 6 through the turnbuckles 4, and each torsion spring 7 is mounted on the main beam; a conveyor roller 8 is rotatably mounted on the main beam, and a filter cloth is provided on the conveyor roller 8; the torsion spring 7 indirectly applies an elastic force to the crossbeam 2 to rotate it until the scraper 1 is in contact with the filter cloth.

[0031] The scraper 1 is fixedly connected to the crossbeam 2 by fastening bolts. The scraper 1 is an arc-shaped flexible scraper 1, made of polyether high-performance polymer, which has excellent wear resistance.

[0032] Optionally, in this embodiment, the device further includes a fixing plate 12, which is fixedly connected to the crossbeam 2 and the scraper 1 respectively. The fixing plate 12 achieves a stable connection between the crossbeam 2 and the scraper 1. The fixing plate 12 has multiple anti-vibration holes.

[0033] Optionally, in this embodiment, two fixed side plates 3 are provided, with each fixed side plate 3 positioned on one side of the crossbeam 2. The fixed side plates 3 are used to support the crossbeam 2, and by providing two fixed side plates 3, a stable connection between the crossbeam 2 and the main beam is achieved.

[0034] The device also includes bearings, and the crossbeam 2 is rotatably connected to the fixed side plate 3 via the bearings. The rotatable connection between the crossbeam 2 and the fixed side plate 3 is achieved through the bearings. In this embodiment, a thrust bearing is used.

[0035] This device also includes mounting bolts. The fixed side plate 3 is fixedly connected to the main beam by the mounting bolts, and anti-corrosion plugs are installed at the ends of the mounting bolts. The mounting bolts connect the fixed side plate 3 to the main beam, and the anti-corrosion plugs at the ends of the mounting bolts protect the mounting bolts.

[0036] Optionally, in an embodiment, the device further includes a spring fixing plate, on which the torsion spring 7 is mounted, and the spring fixing plate is fixedly connected to the main beam.

[0037] Specifically, the spring fixing plate includes a base plate 13, a mounting shaft 14, and an end plate 15. The base plate 13 is fixedly connected to the main beam. One end of the mounting shaft 14 is fixedly connected to the base plate 13. A torsion spring 7 is fitted onto the mounting shaft 14. The other end of the mounting shaft 14 is fixedly connected to one end of the end plate 15. A side plate 16 is fixedly connected to the other end of the end plate 15. The side plate 16 is set parallel to the mounting shaft 14. One end of the torsion spring 7 abuts against the side plate 16. The other end of the torsion spring 7 is fixedly connected to the turnbuckle 4.

[0038] By setting the mounting shaft 14, the torsion spring 7 can rotate around the mounting shaft 14, and the end plate 15 is set to limit the torsion spring 7. One end of the torsion spring 7 is fixedly connected to the turnbuckle 4, and the other end abuts against the side plate 16. When the turnbuckle 4 applies a tension force to the torsion spring 7, the torsion spring 7 rotates and stores energy. When the tension force is removed, the energy is released to generate rotational force, realizing rotational reset.

[0039] Optionally, in this embodiment, mounting plates 9 are rotatably connected to both ends of the conveyor roller 8, and the mounting plates 9 are fixedly connected to the main beam. The connection between the conveyor roller 8 and the main beam is achieved through the mounting plates 9.

[0040] The device also includes a baffle 10 and a spring 11. The baffle 10 is fixedly connected to the conveyor roller 8, and the spring 11 is fitted onto the conveyor roller 8. The spring 11 is located between the baffle 10 and the mounting plate 9.

[0041] During operation, the conveyor roller 8 rotates, and as the conveyor roller 8 rotates, the spring 11 vibrates. The vibration of the spring 11 effectively removes the solid plaster adhering to the connection between the conveyor roller 8 and the mounting plate 9.

[0042] After the device is installed, as follows Figure 1 As shown, chain 6 and turnbuckle 4 are aligned in a straight line. The ends of swing arm 5, chain 6, turnbuckle 4, and torsion spring 7 together form a "Z" shape. Under the influence of gravity, scraper 1 is in contact with conveyor roller 8, at which point chain 6 is taut. In actual operation, the overall length of turnbuckle 4 and chain 6 can be adjusted by adjusting turnbuckle 4.

[0043] During use, the filter cloth passes between the scraper 1 and the conveyor roller 8. Due to the thickness of the filter cloth and solid plaster, the scraper 1 is raised at a certain angle. This causes the crossbeam 2 to rotate, which in turn drives the swing arm 5 to rotate. The swing arm 5 pulls the chain 6 and the turnbuckle 4, which transmits the tension to the torsion spring 7, causing the torsion spring 7 to rotate. This rotation stores energy in the torsion spring 7, generating a rotational force opposite to the direction of rotation. This rotational force is transmitted to the crossbeam 2 via the turnbuckle 4, chain 6, and swing arm 5, ensuring that the scraper 1 adheres tightly to the filter cloth.

[0044] In summary, this device is suitable for cleaning gypsum in vacuum belt dewatering machines, and it achieves automatic adjustment of the distance between the scraper 1 and the filter cloth. This device can precisely control the angle and pressure of the scraper 1, so that solid gypsum can be smoothly separated from the surface of the filter cloth, effectively preventing damage to the filter cloth due to excessive local pressure, and ensuring the integrity and service life of the filter cloth.
