Problems solved by technology

When the filter capacity of the dust collector on the top of the warehouse is insufficient, the pressure in the powder storage chamber will be higher than the opening pressure of the safety valve in an instant, the safety valve will open, and the powder-air mixture will leak out through the safety valve. When the pressure of the cavity is too high, it may also cause the top of the powder tank to be torn or opened, resulting in immeasurable losses and a great safety hazard

Abstract

The invention relates to a powder tank which comprises a silo, a feeding pipe, a safety valve and a dust collector, wherein the silo forms a powder storage cavity, the feeding pipe is communicated with the powder storage cavity, and the dust collector is mounted between the powder storage cavity and the outside; and a buffer box is arranged on the silo, the buffer box is provided with an inlet and an outlet, the inlet is communicated with the upper part of the powder storage cavity, the outlet is communicated with the lower part of the powder storage cavity through a buffer pipeline, and a dust remover is arranged on the buffer box. According to the powder tank, the buffer box is arranged on the silo, so that air pressure produced under the condition that pressure is kept down is subjected to buffer processing through the buffer box; and at the same time, by the aid of the action of the dust remover on the buffer box, the pressure of the powder storage cavity cannot be higher than the opening pressure of the safety valve at an instant, so that the safety valve cannot be opened, and a powder and air mixture cannot leak through the safety valve.

Description

technical field [0001] The invention belongs to the technical field of construction machinery, and in particular relates to a powder tank. Background technique [0002] At present, the dust collector used in the powder tank of the mixing station is a dust collector on the top of the warehouse, that is, a dust collector is installed on the top of the large tank. During use, the high-pressure gas containing a large amount of dust directly enters the dust collector, and after being filtered by the filter element, the gas is discharged into the atmosphere, and the dust falls back into the large tank. [0003] Under normal circumstances, the requirements for the filtration capacity of the warehouse roof dust collector are relatively low. The dust collector on the top of the warehouse can discharge the air in the powder-air mixture in time, so that the pressure in the powder storage chamber is lower than the opening pressure of the safety valve; and then the safety valve can be k...
