A resin sand processing production line

Abstract

The invention discloses a resin sand processing production line, which includes an old sand recovery and regeneration device, a new sand conveying device and a pneumatic device, and the old sand recovery and regeneration device includes a drum shakeout machine, a vibration regeneration machine, a suspension magnetic separator, and a rotor regeneration machine The old sand is crushed by the vibrating regenerator after being shaken out from the drum shakeout machine, then regenerated by the rotor regenerator after being demagnetized by the magnetic separator, and finally mixed with new sand and then entered into the double-arm sand mixer by means of an air supply device; the drum One side of the shakeout machine is fed with heated compressed air to evaporate water; the pneumatic device provides the compressed air required by the drum shakeout machine and the industrial air for the air delivery device through the air compressor. The resin sand processing production line of the present invention uses pneumatic devices to install different compressed air to the drum shakeout machine and air delivery device, rationally utilizes resources, reduces damage to molded castings, and improves the recycling value of resin sand.

Description

technical field [0001] The invention relates to the field of pig iron casting, in particular to a resin sand processing production line. Background technique [0002] Resin sand is particles made of thermoplastic acrylic or thermosetting amine materials. Resin sand can cast more than 70% of tools. In the process of producing resin sand casting tools, a lot of waste resin sand will be produced. If the waste resin sand is not treated, it will not only It will cause a lot of waste of resources and cause environmental pollution. After the resin sand is poured to form a mold, if the binder in it has not undergone irreversible changes, it only needs to remove impurities, and the original performance can be restored after ash absorption, cooling and re-mixing; and the use of chemically hardened sand molds and For sand cores, the hardening reaction of the binder is irreversible. In this case, the old resin sand cannot be reused simply, and resin sand recycling equipment and product...

[0002] Resin sand is particles made of thermoplastic acrylic or thermosetting amine materials. Resin sand can cast more than 70% of tools. In the process of producing resin sand casting tools, a lot of waste resin sand will be produced. If the waste resin sand is not treated, it will not only It will cause a lot of waste of resources and cause environmental pollution

After the resin sand is poured to form a mold, if the binder in it has not undergone irreversible changes, it only needs to remove impurities, and the original performance can be restored after ash absorption, cooling and re-mixing; and the use of chemically hardened sand molds and For sand cores, the hardening reaction of the binder is irreversible. In this case, the old resin sand cannot be reused simply, and resin sand recycling equipment and production lines are required.
