Problems solved by technology

[0002] The regeneration of foundry used sand can effectively solve the problem of shortage of sand resources. Due to the cost problem of the existing used sand regeneration device, mechanical equipment still accounts for the vast majority in the production process, and most of the mechanical equipment structure is relatively complicated, and the recovery efficiency The quality of the recovered used sand is also relatively poor, and most of the equipment's sand input and sand output methods are intermittent, which greatly affects the efficiency of used sand recovery and regeneration

Abstract

The invention discloses an efficient double rotation regeneration device for foundry used sand. The efficient double rotation regeneration device for the foundry used sand comprises a vertically arranged sand cylinder, a rotating shaft arranged on the center axis of the sand cylinder, a first rotary motor coaxially connected to the top end of the rotating shaft, a transmission gear arranged at the position of the geometric center of the bottom of the sand cylinder, a second rotary motor in transmission cooperation with the transmission gear, and a sand cylinder support; first downwards-inclined crushing and stirring rods are arranged above the rotating shaft; the position, below the first crushing and stirring rods, on the rotating shaft is provided with spiral blades; the inner wall of the sand cylinder is provided with second downwards-inclined crushing and stirring rods; slide rails are arranged on the sand cylinder in a horizontal encircling manner; and slide grooves matched with the slide rails are arranged on the sand cylinder support. According to the efficient double rotation regeneration device for the foundry used sand, due to opposite rotation of the sand cylinder and the rotating shaft, the foundry used sand achieves sufficient friction, an inert membrane on the surface of the used sand is more effectively removed, the regeneration quality and efficiency of the used sand is improved, and regeneration of the used sand can be continuously performed.

Description

technical field [0001] The invention relates to a recycling device for used casting sand, in particular to a double-rotation recycling device for high-efficiency casting used sand. Background technique [0002] The regeneration of foundry used sand can effectively solve the problem of shortage of sand resources. Due to the cost problem of the existing used sand regeneration device, mechanical equipment still accounts for the vast majority in the production process, and most of the mechanical equipment structure is relatively complicated, and the recovery efficiency The quality of the recovered used sand is also relatively poor, and most of the equipment's sand input and sand output methods are intermittent, which greatly affects the efficiency of used sand recovery and regeneration. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-efficiency dual-rotation regeneration device for used sand in casting, which ...
