Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and in particular to a hoisting machine with a dust collection function. Background Technology

[0002] A bucket elevator is a continuous conveying machine that uses a series of buckets fixed to a traction chain or conveyor belt to transport bulk materials upward in a vertical or near-vertical direction. The lower part of the bucket elevator casing has a feed inlet, and the upper part has a discharge outlet. When the buckets pass the highest point, the centrifugal force during rotation and the force of gravity they experience will tilt the material into the discharge outlet, from which it will be discharged.

[0003] Traditional vertical elevators have certain drawbacks in the conveying of materials that easily generate dust, such as grains and mineral powders: dust adhering to the surface of the material is easily dispersed inside the elevator during the lifting process; conventional fixed cleaning devices have blind spots and are prone to wear on the conveyor belt; and dust removal systems using single-point negative pressure adsorption are difficult to cover multiple pollution sources such as dust generated during feeding, dust dispersed during discharging, and dust accumulated inside the equipment, resulting in insufficient dust removal efficiency.

[0004] Therefore, it is necessary to provide a lifting machine with a dust collection function to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a hoist with a dust collection function, which solves the problems of secondary dust dispersion caused by incomplete cleaning of the conveyor belt surface, wear and tear on the conveyor belt caused by the cleaning device, and low dust removal efficiency caused by insufficient coverage of multiple dust sources by the single-point dust removal system.

A first installation area 7 and a second installation area 9 are provided on the side of the lifting machine body 1. An air jet assembly 8 is provided in the first installation area 7, and an adjustable cleaning assembly 10 is provided in the second installation area 9, which together clean the surface of the lifting section 4 passing over the return ramp 6. A guide ramp 11 is provided below the return ramp 6. A discharge port 12 is provided at the bottom of the lifting machine body 1, and a partition plate 13 is provided at the discharge port 12 to block the impurities that are cleaned down. A feeding section 14 and a dust collection section 15 are provided on the outside of the lifting machine body 1.

[0030] Material enters the lifting section 4 from the feeding section 14 and is conveyed to the discharge ramp 5 to leave. After the jet assembly 8 removes the dust from the surface of the lifting section 4, the adjustable cleaning assembly 10 performs a second cleaning. After cleaning, the residual dust is discharged through the return ramp 6 and the guide ramp 11. The dust suction section 15 adsorbs the dust, impurities, dust and materials that have not been lifted by the lifting section 4 and leave the discharge port 12 from both sides of the partition plate 13.

[0031] The lifting section 4 includes a first drive motor 41 and a support roller 42. The support roller 42 is rotatably connected to the side plate 2. A conveyor belt 43 is provided on the outer side of the support roller 42. A plurality of equally spaced bearing plates 44 are provided on the conveyor belt 43, which will drive the material entering from the feeding section 14 to move upward.

[0032] The lifting section 4 uses a first drive motor 41 to drive the support roller 42 to drive the conveyor belt 43 to rotate, and the equally spaced bearing plates 44 form a continuous material carrying unit.

[0033] The jet assembly 8 includes an air extractor 81 with an air inlet 82 and multiple equally spaced airflow nozzles at the output end of the air extractor 81, which blow air onto the surface of the conveyor belt 43 above the return slope 6 to blow away the adhering dust.

[0034] The jet assembly 8 uses compressed air generated by the air extractor 81 to form a fan-shaped air curtain through multiple sets of airflow nozzles, which can perform non-contact cleaning of the surface of the conveyor belt 43 and remove attached dust.

[0035] The adjustable cleaning assembly 10 includes a second drive motor 101 and a moving rod 1010. The output end of the second drive motor 101 is connected to a drive shaft 102. The end of the drive shaft 102 is fixedly connected to a first turntable 103. The first turntable 103 is provided with an adjusting screw 104 and a limiting plate 105.

[0036] The adjustable sweeping assembly 10 drives the first turntable 103 to rotate via the second drive motor 101. Then, the second turntable 107, which is offset from the center of the first turntable 103, cooperates with the annular limiting groove 108 to achieve the reciprocating motion of the moving rod 1010. Rotating the adjusting screw 104 causes the moving block 106 to slide along the limiting plate 105, thereby adjusting the distance between the center of the second turntable 107 and the first turntable 103, thus achieving the purpose of adjusting the reciprocating motion distance of the roller sweeping brush 1012.

[0037] The feeding section 14 includes a telescopic rod 141, a closed cover plate 142, and a feeding hopper 143. The telescopic rod 141 and the closed cover plate 142 are rotatably connected to the elevator body 1, and the feeding hopper 143 is fixedly connected to the side plate 2.

[0038] The feeding section 14 achieves intelligent adjustment of the opening of the feeding hopper 143 through the linkage design of the telescopic rod 141 and the closed cover plate 142, preventing dust from overflowing.

[0039] The dust collection unit 15 includes a dust collection fan 151 and a dust collection box 152. A first pipe 153 and a second pipe 154 are connected to the dust collection box 152.

After cleaning, the residual dust is discharged through the return ramp 6 and the guide ramp 11. The dust suction section 15 adsorbs the dust, impurities, dust and materials that have not been lifted by the lifting section 4 and leave the discharge port 12 from both sides of the partition plate 13.

[0043] Compared with related technologies, the lifting machine with dust collection function provided by this utility model has the following advantages:

[0044] Beneficial effects:
