A kind of integral casting process of water ring vacuum pump

Abstract

The invention belongs to the technical field of casting, and specifically relates to an integral casting process of a water ring vacuum pump. The sand mixer used in the process includes a support frame, a shell, a material inlet, a material outlet, a No. 1 pipe and a No. 1 motor The middle position inside the support frame is rotatably connected with a shell, and the bottom of the shell is fixedly connected with a grinding disc; one side of the shell is installed with a No. 1 motor, and the output end of the shell and the No. 1 motor is meshed through gears to realize The shell rotates; when the raw sand moves with the shell, because the blades are inclined upward, the raw sand will move to the blades and then roll down, increasing the movement intensity of the raw sand in the shell; after the raw sand moves to the blades, the The through-hole will screen the sand, and leave the large-grained sand to continue grinding and extrusion. The finer sand will pass through the through-hole, and another blade will knead it to wrap the additive, improve the quality of sand mixing, and further improve the sand mixing efficiency. , Reduce sand mixing time, thereby reducing production costs.

Description

Integral casting process of a water ring vacuum pump technical field The invention belongs to casting technical field, specifically a kind of integral casting process of water ring vacuum pump. Background technique Casting is a kind of metal thermal processing technology that human beings have mastered earlier, and has a history of about 6,000 years; Between 1700 BC and 1000 BC, it has entered the heyday of bronze casting, and the technology has reached a very high level; casting It refers to the processing method of melting solid metal into a liquid state and pouring it into a casting mold of a specific shape, and waiting for it to solidify and form; the cast metal includes: Copper, iron, aluminum, tin, lead, etc. Common casting materials are raw sand, clay, water glass, resin and other auxiliary materials; special casting Casting molds include: investment casting, lost foam casting, metal mold casting, ceramic mold casting, etc.; casting defects have always been a ...

AI Technical Summary

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology and solve the problem that when the particle size of the original sand is not uniform, the required processing time will also increase, resulting in an increase in the mixing time after adding additives and reducing the sand mixing efficiency.
