Abstract

The invention provides a frictional regenerator which can be used for treating used sands by virtue of dry reclamation. The frictional regenerator is simple in structure, low in energy consumption, low in cost and good in regeneration effect. The equipment provided by the invention comprises a housing, wherein a sand feeding hopper is mounted on the housing. The frictional regenerator is characterized by further comprising a refiner plate, a transmission shaft and a driving device, wherein the refiner plate comprises a fixed refiner plate and a movable refiner plate which are arranged in the housing; the fixed refiner plate is fixedly arranged on the inner wall of the housing, sand guide holes communicated with the sand feeding hopper are formed, the movable refiner plate is mounted on the end part at one side of a transmission shaft and is parallel to the fixed refiner plate; the end part at the other side of the transmission shaft is supported on the support device, and the transmission shaft is driven by the driving device.

Description

technical field [0001] The invention relates to recycling and processing equipment for used sand in casting production, in particular to dry recycling equipment, in particular to a friction recycling machine. Background technique [0002] There are many existing ways to regenerate old sand, mainly including dry regeneration, wet regeneration, thermal regeneration and chemical regeneration. Dry regeneration has simple equipment, but the quality of regenerated sand is poor; wet regeneration, thermal regeneration Reclaimed sand is of high quality after regeneration by chemical method and regeneration method, but the equipment is complicated, energy consumption is high, and cost is high. Contents of the invention [0003] In view of the above problems, the present invention provides a friction regenerator, which utilizes a dry method to regenerate old sand, has simple equipment structure, low energy consumption, low cost, and good regeneration effect at the same time. [0004...
