Abstract

The invention relates to a dual-tank dense-phase pneumatic conveying device, which is particularly used for conveying powder and dry materials in the forms of fine particles, and belongs to the technical field of machinery equipment. The dual-tank dense-phase pneumatic conveying device comprises a tank body, wherein the upper end of the tank body is connected with a single-direction feeding tube through an upper flange; the lower end of the tank body is connected with a discharging tube through a lower flange; the side face of the tank body is connected with a suction and exhaust valve through a suction and exhaust valve seat; an air cylinder is fixed at the upper end of the single-direction feeding tube; a piston rod of the air cylinder is used for driving an upper conical valve core at the lower end to move up and down through a connecting rod; the side face of the single-direction feeding tube is connected with a telescopic tube through a feeding hole flange; a spring base is fixed in the discharging tube; a rubber air spring is arranged on the lower spring base; the upper end of the rubber air spring is connected with an upper spring base; the upper end of the upper spring base is connected with a lower conical valve; and the rubber air spring can be used for driving the lower conical valve to move up and down. The dual-tank dense-phase pneumatic conveying device has the advantages of simple, compact and reasonable structure, stability, reliability, high production efficiency, good use effect, small floor area, convenience in installing and maintaining, and continuous conveying of materials.

Description

technical field [0001] The invention relates to a double-tank dense-phase pneumatic conveying device, which is used for conveying powder and fine granular dry materials, and belongs to the technical field of mechanical equipment. Background technique [0002] The high-dense phase pneumatic conveying device is a sand conveying system that is widely developed and used in China. In the sand transportation production of resin sand, sodium silicate sand and other dry and new sand required by other processes, the use of high-density phase pneumatic conveying devices is very environmentally friendly, and the materials are completely operated in airtight containers and management. It has the characteristics of long conveying distance, large vertical height and small conveying loss. Another feature of the high-density phase pneumatic conveying device is that it has little environmental pollution, and the sand and dust are decomposed into the sand storage through the dust collector, ...
