Description

Technical Field

[0001] This utility model belongs to the field of hopper cleaning technology, and in particular relates to a hopper cleaning and dust removal device. Background Technology

[0002] A hopper is a device specifically designed for storing and conveying various materials, such as coal, ore, chemical raw materials, and cement. Its main structure is typically made of robust steel plates. However, during long-term use, dust and other impurities tend to accumulate inside the hopper, in the outlet area, and in the connected pipes and related equipment. If not treated promptly, these accumulations can eventually cause blockages, affecting the smooth operation of the equipment and compromising the cleanliness of the working environment.

[0003] Currently, the cleaning and dust removal work for the feeding hopper is generally carried out manually, that is, on-site staff directly use cleaning tools to manually clean the discharge port and the inside of the feeding hopper.

[0004] However, although this method is simple to operate, its significant drawbacks are low efficiency and a greatly increased physical burden on operators. Therefore, finding a more efficient dust removal method that reduces manual labor intensity is particularly important. Based on the above problems, a hopper dust removal device is proposed. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a hopper cleaning and dust removal device, which solves the technical problem that the existing hopper cleaning and dust removal work generally adopts manual cleaning, which is inefficient and greatly increases the physical burden on operators.

[0006] To achieve the above objectives, a hopper cleaning and dust removal device is provided according to an embodiment of the first aspect of the present invention, comprising a frame body and a cleaning and dust removal mechanism;

[0007] The cleaning and dust removal mechanism includes a dust hood, a scraper, a dust collection box fixedly connected to the vehicle frame, and a pair of corrugated dust collection pipes fixedly connected to the top surface of the dust collection box and fixedly connected at the other end to the outside of the dust hood.

[0008] The scraper includes a rotating column rotatably disposed in the middle of the dust collection hood port and an I-shaped scraper fixedly sleeved on the rotating column;

[0009] The dust collection box is equipped with a connected barrier zone and a negative pressure zone. A barrier filter element is fixedly connected in the barrier zone, and a power suction pump is fixedly connected in the negative pressure zone.

[0010] Further improvement lies in that the bottom surface of the dust cover is fixedly connected with a direct current servo motor one, and the main shaft of the direct current servo motor one is connected with the rotating column.

[0011] Further improvement lies in that a downward extending mounting groove is formed at the surface edge of the dust cover, and a telescopic cylinder is slidably arranged in the mounting groove.

[0012] Further improvement lies in that a ring of barrier cloth is fixedly connected to the inner wall surface of the telescopic cylinder, and the bottom surface of the barrier cloth is fixedly connected to the inner wall surface of the dust cover.

[0013] Further improvement lies in that a ring of compression springs is fixedly connected to the inner wall of the bottom surface of the mounting groove, and the bottom surface of the telescopic cylinder is fixedly connected to the top surface of each compression spring.

[0014] Further improvement lies in that the lifting assembly further comprises a lifting cylinder fixedly connected to the frame body, a machine plate fixedly connected to the bottom surface of the lifting cylinder port, a lifting lead screw rotatably arranged at the middle part of the surface of the machine plate, and a lifting column screwed on the lifting lead screw.

[0015] Further improvement lies in that the bottom surface of the dust cover is fixedly connected with a guide seat, the guide seat is movably inserted into the lifting cylinder port, and the bottom surface is fixedly connected with the top surface of the lifting column.

[0016] Further improvement lies in that the bottom surface of the machine plate is fixedly connected with a direct current servo motor two, and the main shaft of the direct current servo motor two is connected with the lifting lead screw.

[0017] Further improvement lies in that a guide column is fixedly connected in parallel on the machine plate and located on both sides of the lifting column, and a guide pipe is movably arranged on the guide column.

[0018] Further improvement lies in that the top end of each guide pipe is fixedly connected with the bottom surface of the guide seat.

[0019] Compared with the prior art, the dust cover has the advantages that:

[0020] The direct current servo motor two is started to drive the lifting lead screw to rotate, so as to adjust the lifting column, the guide seat on the top of the lifting column and the dust cover to lift together until the telescopic cylinder is closely sleeved on the discharge port of the discharge hopper, and the scraper is closely attached to the inner wall of the discharge port. It is worth noting that a ring of compression springs is arranged in the mounting groove, and the bottom surface of the telescopic cylinder is fixedly connected with the top surface of each compression spring. This design allows the telescopic cylinder to adapt to discharge ports of discharge hoppers with different lengths by compressing the compression springs, thereby increasing the versatility of the equipment.

[0021] Next, the DC servo motor one is started, the scraper is driven to work, the I-shaped scraper in the scraper is used for effectively scraping the impurities and dust remaining on the inner wall of the discharge port. At the same time, the power suction pump in the dust removal box starts to work, generates negative pressure suction, sucks the scraped impurities and dust, and deposits them on the barrier filter core. After the cleaning operation is completed, unified treatment is carried out. This design not only greatly simplifies the cleaning process of the discharge port of the lower hopper, but also significantly reduces the labor intensity and greatly improves the cleaning efficiency.

[0034] As shown in FIG. 1, Figure 2 As shown in FIG. 1,

[0035] The lifting assembly comprises a lifting cylinder 2 fixedly connected to the frame body 3, a machine plate 21 fixedly connected to the bottom surface of the port of the lifting cylinder 2, a lifting lead screw 22 rotatably arranged in the middle part of the surface of the machine plate 21, and a lifting column 23 threadedly sleeved on the lifting lead screw 22;
