Anti-corrosion fluid conveying machine for chemical production

Abstract

The invention relates to an anti-corrosion fluid conveying machine for chemical production. The machine comprises a material box, a controller, an air inlet pipe, a transverse pipe, a vertical pipe, aliquid outlet pipe and a liquid injection mechanism. A compression mechanism comprises a swing assembly, a swing rod and two compression assemblies, wherein the compression assembly comprises a compression pipe, an air injection pipe, a compression plate, a vertical rod and a lantern ring; and a purification mechanism comprises a filter screen, a rotating assembly, a cross rod, a circular ring, arotating rod and a plurality of springs. According to the anti-corrosion fluid conveying machine for chemical production, the compression plate continuously presses a solution in the material box into the liquid outlet pipe through taking air as a medium through the compression mechanism, so that the conveying function is realized, and the compression plate is prevented from being corroded due tothe contact with the solution; moreover, the air entering the vertical pipe is purified through a filtering mechanism, the rotating rod can be driven to rotate through the rotating assembly, the filter screen is cleaned and dredged, and it is ensured that the air circulation is smooth, so that the practicability of the equipment is further improved.

Description

technical field [0001] The invention relates to the field of chemical production equipment, in particular to an anti-corrosion fluid conveying machine for chemical production. Background technique [0002] In the chemical production process, fluid transportation is the most common and even indispensable unit operation. Fluid conveying machinery is a device that does work to the fluid to increase the mechanical energy of the fluid. Therefore, after the fluid conveying machinery is running, the fluid can obtain energy to overcome the loss of mechanical energy along the fluid conveying process, increase the potential energy and increase the liquid pressure (or decompression, etc. ). Generally, the machinery that transports liquid is called a pump; the machine that transports gas is called a fan, blower, compressor and vacuum pump according to the pressure it generates.

Problems solved by technology

[0003] Traditional liquid conveying machinery, that is, during the operation of the pump, most of them rely on the rotation of the impeller to generate negative pressure. The liquid is sucked into the pump casing and then discharged from the discharge pipe. The impeller is in contact with the liquid. The remaining part transports the liquid, and these liquids are in contact with the impeller, which is easy to corrode the impeller and reduce the transport efficiency of the liquid transport machinery. After long-term use, it will also cause equipment damage, which in turn will reduce the practicability of the existing chemical production fluid transport machinery
