Description

TECHNICAL FIELD

[0001] The application relates to the technical field of dust conveying, in particular to a dust conveying device for a mine bag-type dust collector. BACKGROUND

[0002] In the production process of mining and processing, a large amount of dust is generated. In order to protect the environment and the health of workers, a bag-type dust collector is usually used to treat dust-containing gas. The bag-type dust collector captures dust particles in the dust-containing gas through a filter bag. Over time, a large amount of dust accumulates on the filter bag. These dusts need to be removed and treated regularly to ensure the normal operation and dust removal efficiency of the bag-type dust collector.

[0003] At present, a screw conveyor is generally used to convey the dust in the mine bag-type dust collector. A motor drives the rotation of a screw shaft, and the screw blades on the screw shaft push the dust to move along the conveying groove or conveying pipeline. The dust is conveyed from the inlet to the outlet under the pushing of the rotating screw blades. For example, in some small mine bag-type dust collector supporting equipment, the dust enters the inlet of the screw conveyor and is gradually pushed to the discharge port by the screw blades.

[0004] For example, the patent with publication number CN220222367U specifically discloses a screw conveyor, which comprises a screw conveyor body, an anti-blocking mechanism, a second driving motor, a second rotating rod, a discharge port, a lead screw, and an adjusting plate. The setting of the adjusting plate ensures that the lumps condensed in the material are broken up, thereby ensuring that the material does not block when entering the screw conveyor body.

[0005] In the dust conveying process of the above patent, the environmental humidity of the mine is not constant, but fluctuates. When the environmental humidity increases, the mine dust will be affected, and its humidity will also increase. At this time, the physical properties of the dust will change, and the flowability will obviously deteriorate. In this case, when the dust with increased humidity enters the screw conveyor and is conveyed to the discharge port position, due to the high humidity of the dust, its viscosity will increase, and when passing through the discharge port, it will tend to adhere to the inner wall of the discharge port. With the passage of time and the continuous accumulation of dust, the adhered dust will gradually gather together to form lumps, which will seriously hinder the normal passage of subsequent dust, thereby causing the discharge port to be blocked. Therefore, a dust conveying device for a mine bag-type dust collector needs to be designed to solve the above problems.

[0006] It should be noted that the above information disclosed in this background section is only used to understand the background technology of the present application, and therefore, it can contain information that does not constitute prior art. SUMMARY

[0025] A discharge port 15 is formed at one end of the screw conveyor body 1, a first driving member 13 is fixedly installed at one end of the screw conveyor body 1, which can be a motor, an output end of the first driving member 13 penetrates one end of the screw conveyor body 1, a screw conveying shaft 14 is fixedly installed at the output end of the first driving member 13, the screw conveying shaft 14 is inside the screw conveyor body 1, and screw blades (not marked in the figure) are fixedly installed on the screw conveying shaft 14;

[0026] When the screw conveying shaft 14 rotates, the screw blades on the screw conveying shaft 14 will push the ash from one side of the feed inlet 12 to the other side of the discharge port 15, because of the shape and rotation characteristics of the screw blades, an axial propulsion force is generated on the ash, so that the ash advances in the axial direction in the screw conveyor body 1, and with the continuous rotation of the screw conveying shaft 14, the ash entering from the feed inlet 12 is continuously pushed to the discharge port 15, realizing the conveying function of the ash collected by the bag dust collector;

[0027] A anti-blocking assembly 2 is installed in the discharge port 15, the anti-blocking assembly 2 includes a discharge pipe 21 fixedly installed in the discharge port 15, the discharge pipe 21 is conical, a fixed ring 22 is fixedly sleeved and installed on the discharge pipe 21, an installation plate 23 is fixedly installed on the side of the fixed ring 22, a second driving member 24 is fixedly installed on the side of the installation plate 23, a first gear 25 is fixedly installed on the output end of the second driving member 24, and the first gear 25 can rotate with the output end of the second driving member 24;

[0028] A second gear 26 is bearingly installed on the discharge pipe 21, the second gear 26 is engaged with the first gear 25, the second gear 26 is suitable for synchronous rotation with the rotation of the first gear 25, two groups of supporting members 210 are fixedly installed symmetrically at the bottom of the second gear 26, an installation seat 211 is fixedly installed on the supporting member 210, and a clamping ring 212 is movably inserted into the installation seat 211, the clamping ring 212 has an insertion end, a screw groove is formed on the insertion end, the clamping ring 212 is movably inserted into the installation seat 211 through the insertion end, and a nut 213 is threadedly connected to the insertion end;

[0030] When the second drive 24 (usually motor) starts to work, its output end starts to rotate, since the first gear 25 is fixedly installed on the output end of the second drive 24, so the first gear 25 will rotate with the output end of the second drive 24, when the first gear 25 rotates, it will drive the second gear 26 to rotate synchronously. The second gear 26 is installed on the discharge pipe 21 through the bearing, which ensures the smoothness of its rotation.

[0031] The bottom of the second gear 26 is symmetrically fixedly installed with two groups of supporting members 210, the mounting seat 211 on the supporting member 210 provides the mounting position for the clasp 212, the clasp 212 is movably inserted into the mounting seat 211 through its insertion end, and the clasp 212 is fixed on the mounting seat 211 by using the nut 213 and the screw groove thread connection, and one end of the fixed rod 29 is fixedly installed on the clasp 212, the first scraper arm rod 27 is installed on the fixed rod 29, and the second scraper arm rod 28 is connected between the two groups of first scraper arm rod 27, thus forming a scraper arm rod structure.

When dust or accumulated dust appears in the discharge pipe 21 of the discharge port 15, the rotating first scraper arm rod 27 and the second scraper arm rod 28 will scrape the inner wall of the discharge pipe 21. Since the discharge pipe 21 is conical, the rotating scraper arm rod can clean the accumulated dust on the pipe wall from different angles. The first scraper arm rod 27 can remove the accumulated dust in the local area of the pipe wall, and the second scraper arm rod 28 can further expand the cleaning range to remove the accumulated dust that may accumulate on the pipe wall.

[0033] The rotating scraping of the scraper arm rod can prevent the accumulated dust from sticking and accumulating in the discharge pipe 21 of the discharge port 15, so that the accumulated dust can smoothly pass through the discharge pipe 21 and avoid the blockage of the discharge port 15 due to the accumulation of the accumulated dust. Even if the accumulated dust has certain viscosity or humidity, the continuous scraping of the scraper arm rod can ensure the smoothness of the discharge port 15, thereby ensuring the normal operation of the entire screw conveyor;

[0034] At the same time, the scraper arm rod is connected with the mounting seat 211 by means of bolt connection through the clasp 212, which can replace and disassemble the scraper arm rod used for a long time;
