Description
Technical Field
The utility model belongs to the technical field of the building, a concrete mixing plant cement tank dust collector is related to.
Background
The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.
Concrete, referred to as "concrete" for short: refers to the general name of engineering composite materials formed by cementing aggregate into a whole by cementing materials. The term concrete generally refers to cement as the cementing material and sand and stone as the aggregate; the cement concrete is also called as common concrete and is obtained by mixing the cement concrete and water (which can contain additives and admixture) according to a certain proportion and stirring.
The cement silo in the concrete mixing plant is generally used in bulk cement storage of the concrete mixing plant, and the bulk cement silo is a closed tank for storing bulk materials. The material conveying of the cement tank takes high-pressure air as a power source, and the pressure in the tank is greater than the atmospheric pressure in the conveying process. In the conventional structure, compressed air in a cement tank is released outwards through a bin top dust remover installed at the top of the cement tank.
during the process of conveying materials into a cement tank, roof fall accidents often occur. The main reasons for roof fall accidents are two: 1. when dust in the cement tank blocks a filter element in the dust remover at the top of the silo along with the high-pressure air in the discharge process, the high-pressure air in the cement tank cannot be discharged, so that the pressure in the cement tank gradually rises, and roof fall is generated. 2. If when filling the material in to the cement jar, even the staff hears the cement jar and beats full alarm, stops the feeding immediately, also can appear the condition of roof fall, causes the extravagant and environmental destruction of material, and the storehouse top dust remover that will irritate the top alone still flies, still has the potential safety hazard that the people was hindered to the junk when dropping.
For reason 1, current solution is at cement jar top installation safety relief valve, and when the filter core in the dust remover of storehouse top was blockked up by the dust, opened safety relief valve, can reduce the pressure in the cement jar to avoid the roof fall accident. However to reason 2, even install safety relief valve, but because the cement jar has been filled with the material, open safety relief valve this moment and can lead to the jam of safety relief valve, from making safety relief valve's pressure release effect inefficacy, pressure in the cement jar is higher than atmospheric pressure simultaneously for the material gets into the storehouse top dust remover, blocks up the passageway that gaseous entering dust remover, thereby causes the roof fall accident, and this reason belongs to human negligence completely, and is unavoidable, does not have the solution of this roof fall reason temporarily.
