Wet-pressing molding centralized drainage vacuum system

Abstract

The invention discloses a wet-pressing molding centralized vacuum drainage system, comprising double-vacuum pump groups, a vacuum tank, a moisture separator and a valve. The technical points of the system are as follows: the outlet ends of two groups of double-vacuum pumps arranged in parallel are communicated by a three-way valve, a negative pressure vacuum tank and the moisture separator in turn, and the outlet ends on the top part of the moisture separator is communicated with the inlet ends of at least two hydraulic press moulds arranged in parallel by an anti-corrosion pipeline and the valve; the vacuum degree in the system is maintained in a constant range; and the end part of a water drain pipe at the bottom part of the moisture separator is also provided with a flip-style drainage door with a rubber gasket. The vacuum drainage system reduces the work noise, power consumption and floor area of the pumps; the reciprocating vacuum pump groups are connected with a large vacuum tank through the three-way valve to keep the vacuum degree of the whole system stable, thereby improving the molding efficiency in pressing slugs; meanwhile, all pipelines adopt PC plastic pipes and the mode of embedding pipes underground, thereby reducing the amount of the maintenance of the pipelines.

Description

technical field [0001] The invention relates to the technical field of drainage vacuum system design, in particular to a wet-press forming centralized drainage system that can improve blank forming efficiency and reduce energy consumption, noise and maintenance in the wet forming process of permanent magnet ferrite vacuum system. Background technique [0002] The technology of permanent magnet ferrite has been quite mature so far, but the production of high-performance permanent magnet ferrite products still widely adopts the molding process of wet pressing magnetic field. In order to ensure the blank quality and production efficiency, a vacuum drainage system is used in the wet pressing process. At present, the vast majority of manufacturers still use water ring vacuum pumps to vacuumize and drain each hydraulic press, but this method has disadvantages such as low vacuum efficiency, large floor space, large working noise, and heavy maintenance workload, which is not conduc...
