Heating type stock bin breathing device

Abstract

The invention discloses a heating type stock bin breathing device. The heating stock bin breathing device comprises a body system composed of an inner shell, an outer shell, a filter element, a connection flange, a filter element fixing flange and a cover plate, a heating system composed of a hot fluid medium inlet pipeline, a hot fluid medium outlet pipe and a jacket formed by the inner shell and the outer shell or a heating system composed of a tracing pipe, aluminum foil and a heat-preserving layer, and an ash removing system composed of a cylinder, an electromagnetic valve, a pulse pipeline and an exhausting pipeline. The heating type stock bin breathing device has the beneficial effects that the breathing device is simple in device technology and elements can be maintained and replaced conveniently; vibration dust removal or pulse jet cleaning dust removal is performed, powder attached to the filter element can be cleared away regularly, and equipment resistance cannot be increased; after the temperature of the wall face of the inner shell and the temperature around the filter element are raised properly, water vapor carried by airflow in a stock bin cannot form water drops on the surface of an object, and therefore the situations that bag pasting happens to the filter element and the inner shell and the exhausting pipeline cake and are blocked cannot be caused; and the frequency of overhead work is greatly reduced, and workloads and dangerousness of maintenance are reduced.

Description

technical field [0001] The invention relates to the technical field of silos, in particular to a heated silo breathing device. Background technique [0002] In the field of powder technology, loading, unloading, transportation, storage, use, technical equipment matching in each link must give full play to the potential of the equipment, short transit cycle and high utilization rate, in order to meet the production requirements. [0003] In production practice, when the material is loaded and unloaded, the volume of the gas in the silo is changing, and a breathing device is needed to balance the pressure inside and outside the silo. During the material loading process, the gas needs to be discharged out of the warehouse through the breathing device; during the material unloading process, the gas outside the warehouse needs to be sucked into the warehouse through the breathing device. The finished material usually has a certain temperature and moisture, and the moisture is ea...

AI Technical Summary

Problems solved by technology

[0010] (1) The air outside the silo cannot enter the silo, and a certain degree of vacuum in the silo will cause the materials in the silo to be unable to be discharged out of the silo smoothly;

[0011] (2) The pressure inside the silo cannot be discharged to the outside of the silo, which will cause unsmooth loading, frequent action of the safety valve, dust escape to the outside of the silo, and pollute the environment;

[0012] (3) The replacement and maintenance workload is huge, and the wet powder sticks to the inside of the breathing device, which is difficult to clean up, and it is a high-altitude operation, which poses certain safety hazards
