Description

Technical Field

[0001] This utility model relates to the field of bar and wire rolling technology, specifically a special dust collection box. Background Technology

[0002] During the steel rolling mill production process, sawing steel generates a large amount of sawdust. If this waste is not cleaned up in a timely manner, it will not only affect the production environment but may also threaten equipment operation and product quality. Dust collection boxes, as a highly efficient industrial dust removal device, are of significant necessity and practicality in cleaning sawdust.

[0003] The dust collection box can collect sawdust in a timely manner through negative pressure suction, reducing the dust concentration in the workshop and eliminating the risk of explosion. If sawdust accumulates in the equipment guide rails, transmission parts or inside the motor, it will aggravate mechanical wear, causing equipment to jam, overheat or even stop. The dust collection box can clean sawdust in real time, extend the equipment life and reduce maintenance costs.

[0004] However, existing dust collection boxes still have many limitations. The sawdust produced by steel rolling sawing may contain a mixture of metal scraps, grease, coolant and other substances, which has a certain stickiness, making it difficult to clean the sawdust and taking too long to dump, thus increasing the difficulty of manual labor. High-temperature sawdust can deform the internal lining plates, and replacement and maintenance require machine shutdown, which affects production efficiency and increases time costs.

[0005] Therefore, there is an urgent need to develop a dedicated dust collection box to solve the problems of difficult sawdust cleaning and deformation of internal lining plates in existing technologies. Utility Model Content

[0006] In view of the above facts, in order to solve the problems of difficult sawdust cleaning and deformation of internal lining plates in the prior art, this utility model designs a special dust collection box.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A special dust collection box includes a dust collection box body, a first lifting plate, a second lifting plate, a third lifting plate, a reinforcing rib plate, and a lining plate;

[0009] The main body of the dust collection box is a cuboid structure with an opening on the right side. The top is provided with an inclined slope, and the first lifting plates are provided on both sides of the inclined slope. The bottom is provided with a chamfered slope, and the second lifting plates are provided on both sides of the chamfered slope. The third lifting plate is provided at the center of the bottom left side of the main body of the dust collection box.

[0010] The bottom surface, chamfered surface, and right side of the dust collection box body are provided with protrusions, and the front, back, left side, and inclined surface of the dust collection box body are provided with reinforcing ribs, which are connected to the protrusions.

[0011] The two longitudinal reinforcing ribs are arranged perpendicularly to the several transverse reinforcing ribs;

[0012] The dust collection box body is equipped with a lining plate inside, forming an inwardly tightening trapezoidal structure.

[0013] Furthermore, the bottom of the reinforcing rib is alternately provided with gaps.

[0014] Furthermore, the height of the protrusion is consistent with the height of the reinforcing rib.

[0015] Furthermore, the liner plate is made of Q345D low-alloy high-strength structural steel plate.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model is equipped with reinforcing ribs, which divide the dust collection box into smaller stress units, disperse the stress generated by negative pressure, and avoid local deformation.

[0018] 2. The bottom of the reinforcing rib in this utility model is provided with a gap to eliminate thermal expansion and contraction stress, avoid structural damage caused by rigid connection, facilitate inspection, maintenance and cleaning, and improve the convenience of operation.

[0019] 3. The internal structure of this utility model is trapezoidal, which utilizes the weight of the sawdust to achieve gravity sliding, avoiding the accumulation of dust in the traditional flat-bottom structure. It can remove all sawdust in one dumping, reducing the sawdust dumping time from 40-120 minutes to 10-15 minutes, thus improving the efficiency of sawdust cleaning.

[0020] 4. This utility model can increase output, with the 850 rolling line increasing production by 3802 tons per year.

[0021] 5. This utility model can extend the service life by more than 3 times, reduce the cost of steel consumption per ton from the original 2.16 yuan / ton to 0.61 yuan / ton, and reduce the annual spare parts cost by 139,500 yuan. Attached Figure Description
