Description

Technical Field

[0001] The present invention relates to the technical field of silo equipment, and in particular to a silo dredging device. Background Art

[0002] In the field of coal mine production and circulation, silos are one of the main material (coal, gangue, etc.) storage facilities. Silos usually adopt a vertical structure with a cylindrical upper part and a closed lower part. Materials are fed in from the upper part and discharged from the lower part. Feeding equipment is usually installed at the lower discharge port. During the storage of materials in the silo, if the materials are stored for a long time, the materials contain moisture, or the material blocks are of different sizes and shapes, the resistance to the materials falling at the closed end of the silo will increase, causing the materials to squeeze each other. When the resistance caused by the squeezing exceeds the gravity of the upper materials, the upper materials will no longer fall, forming a dome-shaped fault in the coal bunker, namely a dome-shaped silo.

[0003] At present, the methods for solving bunker bulges include explosive blasting, air cannon vibration method and manual poking bunker mouth clearing method. Among them: explosive vibration blasting method is easy to collapse bunker mouth and bunker wall, causing safety hazards; air cannon vibration method has the problem of treating local bunker bulges, and the treatment effect is not great when there is a lot of material in the bunker, and the failure rate is high, it occupies a large space, and it cannot be installed in the bunker underground; the manual poking bunker mouth clearing method has limitations, and can only treat a small amount of material bulges, but cannot handle a large amount of material bulges, and is dangerous. Once the gangue bunker is unblocked, a large amount of gangue will gush out, threatening the lives of people.

[0004] Therefore, a reliable and safe solution for dredging the canopy is urgently needed. Summary of the Invention

[0005] The present invention aims to solve the problem of silo bloating that the existing technology cannot solve safely and reliably, and provides a silo dredging device that can solve the problem of silo bloating in real time, reliably and safely.

[0006] The technical solution of the present invention is: a silo dredging device, including a dredging component and a power component, the dredging component is arranged in the silo from the upper opening to the lower opening of the silo, and the power component includes a first power component and a second power component, the first power component and the second power component are respectively installed at the upper opening and the lower opening of the silo, the upper end of the dredging component is connected to the first power component, and the lower end of the dredging component is connected to the second power component, and the power component can drive the dredging component to move up and down in the silo.

[0007] The dredging component includes a traction member and a material-dispersing protrusion. A plurality of material-dispersing protrusions are arranged at intervals in the length direction of the portion of the traction member located in the silo, and the material-dispersing protrusions are fixed on the traction member.

[0008] The material separation protrusions are arranged at intervals of 1 meter to 5 meters, preferably at intervals of 2 meters to 3 meters.

[0009] The material-reducing protrusions may be in the shape of a disc, a truncated cone, a spindle or a sphere.

[0010] The traction member includes a steel wire rope, a round link chain or other flexible connecting members.

[0011] A sleeve is provided at the location where the traction member passes through the feeding device, which plays a guiding and sealing role for the traction member.

[0012] The outer cylinder of the sleeve is a steel cylinder, and the inner lining sleeve is made of polyurethane, polyethylene polymer, polytetrafluoroethylene or copper.

[0013] The power component is a winch, a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0014] The first power component is movably arranged at the upper opening of the silo.

[0015] The first power component is provided with a roller, and the upper opening of the silo is provided with a guide rail that cooperates with the roller. The first power component can move along the guide rail to expand the dredging area.

[0016] The silo dredging device also includes a force sensor, which is arranged at the connection between the dredging component and the power component, or on the dredging component, or on the power component. The force sensor measures the pulling force of the power component on the dredging component. By measuring the pulling force of the power component on the dredging component, the material level height in the silo can be calculated.

[0017] During use, the first power component relaxes the traction component, and the second power component pulls the traction component downward for a certain distance. Then, the second power component relaxes the traction component, and the first power component pulls the traction component upward for a certain distance. This cycle repeats, and the traction component and the material-dispersing protrusions fixed on the traction component destroy the material bin during the up and down movement, thereby achieving the effect of dredging.

[0018] The beneficial effects of the present invention are:

[0019] 1. The dredging components run through the entire silo vertically, and can effectively dredge material silos at different heights with high efficiency and good dredging effect.

[0020] 2. The process of clearing the bunker can be realized automatically without manual intervention, which is highly safe.

[0021] 3. There is no blasting vibration during dredging, which will not cause damage to the structure of the silo.

[0022] 4. It can be installed and used for silos above and below the well, with good versatility. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The traction member 1.1 is a steel wire rope 1.11, and may also be a round link chain or other flexible connecting member.

[0036] The traction member 1.1 is provided with a sleeve 4 at the location where it passes through the feeding device, which plays a guiding and sealing role for the traction member 1.1.
