Continuous resin sand mixing machine and sand mixing method

Abstract

The invention discloses a continuous resin sand mixing machine and a sand mixing method. The continuous resin sand mixing machine comprises a feeding box and a sand mixing barrel which are arranged horizontally, wherein a rotating device is arranged on the upper part of a supporting device; the feeding box is mounted on the rotating device; a feeding opening is formed in the top of the feeding boxand is connected with a feeder system; a motor is mounted on the horizontal side of the feeding box; the other opposite side of the feeding box communicates with the sand mixing barrel; the cross section of the sand mixing barrel is U-shaped; the resin sand cannot be adhered easily; the space is large; large space is reserved in the upper part of the sand mixing barrel to remove dust and odor effectively; the continuous resin sand mixing machine is environmentally friendly; the sand mixing method is simple and efficient; and the product cost is low.

Description

technical field [0001] The invention belongs to the technical field of sand mixers, and in particular relates to a resin sand continuous sand mixer and a sand mixing method. Background technique [0002] Sand casting is a casting method that produces castings in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. The resin sand mixer is a machine used to mix sand, resin, curing agent and other binders, so as to obtain qualified molding sand for molding. The existing resin sand sand mixer has the disadvantages of low working efficiency, high amount of resin and curing agent, and uneven mixing; not only the production efficiency is low, but the production cost is also very high, and the burned binder after pouring will pollute the atmosphere Also very serious. Many manufacturers have increased the capacity of the mixing tank in order to improve efficiency, but it has increased the processing time and cannot effectively improve prod...

AI Technical Summary

Problems solved by technology

The existing resin sand sand mixer has the disadvantages of low working efficiency, high amount of resin and curing agent, and uneven mixing; not only the production efficiency is low, but the production cost is also very high, and the burned binder after pouring will pollute the atmosphere also very serious

Many manufacturers have increased the capacity of the mixing tank in order to improve efficiency, but it has increased the processing time and cannot effectively improve production efficiency; it cannot effectively reduce the amount of resin and curing agent added
