Description

Pneumatic blowing device for preventing material blockage

Technical Field

The utility model relates to a technical field is carried to the material, specifically indicates an anti-blocking's strength sweeps device.

Background

During the transportation of the material, the material may normally be flowable. However, when the materials are wet, the water content is increased, the bin body oblique angle is too large, the viscosity and the friction force of the bin body oblique angle are increased, the fluidity is reduced, a large amount of materials are easily covered when passing through the discharging port at the same time to form broken materials, and in addition, the materials can be extruded by gravity to be stuck on the bin wall, so that a small amount of materials are stuck on the bin wall more and more thickly for a long time, and a wall is formed. If a thick binder is formed, the binder is difficult to treat at a later stage or needs to be manually treated by shutdown equipment, and in this case, the binder has great influence on the operation and economy of a company and the production safety. In addition, sundries in the materials are easy to block at a lower discharge hole, so that the flowability of the materials is influenced, and the materials are broken.

For the above problems, the existing methods mainly include:

1. a loosening machine: hydraulic pressure loosening machine promotes the rake teeth of installing in the storehouse through hydraulic equipment and clears up hydraulic equipment trouble many to the material, installs the inside hydraulic push rod in storehouse and has inversely formed the strong point of putty, sizing. When the material is stored in the material bin, the hydraulic push rod can move back and forth in the material, and the acting force is not on most of the material. The hydraulic movement frequency is limited, and the material is blocked back and forth once in one minute.

2. Air cannon: the air cannon releases compressed air instantly to generate impact force so as to achieve the purposes that the arch breaking bin only has sticky materials on the bin wall, and the bin cleaning effect is obvious when a gap is formed in the middle of the bin, but only local cleaning can be realized. The bin is blocked, and compressed air cannot penetrate into the material when no gap exists in the middle of the arch lapping material, so that the air cannon cannot be cleaned effectively; moreover, the instantaneous release noise is large; the dust is not environment-friendly, and the dust in the bin cannot be controlled.

3. A vibration motor: the vibrating motor is used for gradually separating the adhesive adhered to the bin wall by the vibration generated by the motor when passing through the eccentric wheel. When the material storage in the bin is large, throwing of the eccentric wheel only can act on the surface of the bin wall, the bin wall is easy to tear, and the frequency of motor burnout, maintenance and maintenance is too high; the effect is obviously low.

4. The pneumatic purging device comprises: the pneumatic blowing device uses high-pressure gas to blow 360 degrees to the place where the material bin wall is easy to aggregate, the working of the pneumatic blowing device adopts an automatic control mode, when the movable impact head is opened, the high-pressure gas is sprayed to the periphery, and after blowing is finished, the impact head returns to the original position through a reset pressure spring, but in the process, the material is easy to enter a cavity, and the membrane of the electromagnetic valve is easy to be damaged.
