Regenerated sand surface impurity cleaning device

Abstract

The reclaimed sand surface impurity cleaning device comprises a box body, a first rotating rod, a second rotating rod and a third rotating rod are sequentially and rotationally connected between the front portion and the rear portion of the inner wall of the box body from left to right, a motor is fixedly connected to the back face of the box body, and the output end of the motor is fixedly connected with one end of the first rotating rod; the invention relates to the technical field of reclaimed sand. According to the reclaimed sand surface impurity cleaning device, the cleaning mechanism comprises a concentric-square-shaped plate and a hydraulic oil cylinder, when the concentric-square-shaped plate moves up and down, air blown out by an air blower can be driven to move up and down, the air blowing range of the air blower can be expanded, more waste is blown and discharged, and the cleaning efficiency is improved. And a partition plate is connected to the bottom of one side of the inner wall of the box body and located on a rotating rod below the discharging pipe, during discharging, only one side of the partition plate needs to be lifted, internal sand grains can roll towards one side, the sand grains can be conveniently discharged out of the box body, adsorbed waste is filtered, and pollution to a production workshop can be reduced.

Description

Technical field [0001] The present invention relates to the field of regenerative sand, in particular a regenerative sand surface impurity cleaning device. Background technique [0002] After the regeneration sand, the casting production is subject to the old sand, sand castings that can be educed back, and the extension of the old sand, the old sand use of the old sand, the use of the old sand, the use of 1 to 7 tons, basically In two ways, that is, the old sand returns and the old sand regeneration, the mold is after the casting, if the binder in most sand is not inversely changed, then as long as the impurities are removed, ascetrating and refurbishment Mixing can restore the original properties, this treatment is called old sand, generally only clay bonded sand can be reused, chemically hardened sand and core (such as oil sand, water glass) Sand and all kinds of sand and cores made of various resin sands), the hardening reaction of its binder is irreversible, and the old sand...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a device for cleaning impurities on the surface of reclaimed sand, which solves the problem that the blowers are concentrated in one place, so that the range of blowing is small, the internal waste discharge rate is low, and there will be more waste Adsorbed on the surface of the cabinet, it is inconvenient to clean up
