Flowing-assisting material bin with built-in inclination-angle-adjustable baffle mechanisms

Abstract

The invention discloses a flowing-assisting material bin with built-in inclination-angle-adjustable baffle mechanisms. The flowing-assisting material bin comprises a flowing-assisting material bin body, at least two layers of inclination-angle-adjustable baffle mechanisms are arranged in a cylinder section of the flowing-assisting material bin body, each inclination-angle-adjustable baffle mechanism comprises at least three adjustable baffles which are uniformly arranged at intervals, the upper portions of the adjustable baffles are movably arranged on the inner wall of the cylinder section through connecting pieces, and the lower portions of the adjustable baffles are connected with one ends of hydraulic rods; and the other ends of the hydraulic rods penetrate out of the flowing-assistingmaterial bin body and is connected with hydraulic cylinders, the hydraulic cylinders are connected with a PLC, and the PLC controls the hydraulic cylinders to work. By the adoption of the technology,the inclination-angle-adjustable baffle mechanisms can achieve a multi-layer storage mode by controlling different inclination angle combinations by the PLC, the filling height of each layer of materials is reduced, the uniform material accumulation density is facilitated, material flowing is better facilitated, and the requirement that the materials go in first and go out first can also be met.

Description

technical field [0001] The invention belongs to the technical field of material storage equipment, and specifically relates to a flow-aiding silo with a built-in tilt-angle adjustable baffle mechanism with adjustable discharge size and smooth discharge, which is suitable for enterprises that need to store materials in chemical, pharmaceutical, and grain industries. It can also be applied to other storage facilities to improve the flow of materials. Background technique [0002] At present, the widely used cylindrical silo is more suitable for granular materials with good fluidity. This kind of materials can form a whole flow under the action of gravity. The advantages are: first-in first-out materials, stable flow, uniform material density, etc. . When conveying other materials with poor fluidity, it is easy to form funnel flow, tubular flow, diffusion flow, arching and other phenomena in the cylindrical silo, resulting in non-first-in first-out of materials, uneven dischar...

AI Technical Summary

Problems solved by technology

When conveying other materials with poor fluidity, it is easy to form funnel flow, tubular flow, diffusion flow, arching and other phenomena in the cylindrical silo, resulting in non-first-in first-out of materials, uneven discharge density, and inability to discharge. Unfavorable factors such as stable flow

The existing measures to improve the fluidity of the silo mainly include: (1) Using the vibration of the silo wall to aid flow. The disadvantage is that in the process of continuous beating and vibration, the material will vibrate more and more solidly, which is not conducive to the material flow

(2) The compressed air arch breaker on the warehouse wall is used to assist flow. The disadvantages are: the compressed air needs to be dehumidified, the compressed air consumes a lot of air, the dust in the warehouse is relatively large, and the material density caused by local injection is not uniform. High power consumption, high noise, etc.

(3) Add unloading mechanical equipment at the outlet of the cone bottom of the silo, such as screw unloader, disc scraper, etc., all of which use mechanical power to provide flow aid. The disadvantages are: uneven material discharge, equipment Lubricating oil leaks polluting materials, tight layout of silo outlet space, etc.

The disadvantage is that the diameter of the discharge port is virtually reduced, resulting in a decrease in the discharge rate

If the material is easy to stick to the wall, it is easy to form arches and other phenomena here, which is not conducive to the flow of materials

(5) There are measures to provide unloading power such as screw unloaders in the silo, but this method has many restrictions. If the height of the silo is high, the shaft diameter of the screw unloader, etc. will be larger and the drive power will be larger. major unfavorable factors
