Crushing and recycling protection device for polystyrene foam board

Abstract

The invention relates to the technical field of polystyrene, and discloses a crushing and recycling protection device for a polystyrene foam board. The crushing and recycling protection device comprises a shell, a material storage box is fixedly connected to the interior of the shell, a spotlight is fixedly connected to the interior of the material storage box, a photosensitive assembly is fixedly connected to the interior of the material storage box, and an electromagnetic valve is fixedly connected to the exterior of the material storage box. Under the interaction of all structures of the device, after entering the device, the polystyrene foam board can be finely crushed through a crushing wheel, the rotating speed of the crushing wheel is detected under the action of a box body and a movable block, when the rotating speed of the crushing wheel is high, the crushing wheel can be decelerated in time under the action between a rotating disc and a stop block, so that the effects that the rotating speed of the crushing wheel can be detected in real time, the crushing wheel can be decelerated when the rotating speed of the crushing wheel is too high are achieved, and then normal machining is guaranteed.

Description

technical field [0001] The invention relates to the technical field of polystyrene, in particular to a crushing recovery protection device for polystyrene foam boards. Background technique [0002] Polystyrene foam board, also known as foam board and EPS board, is a white object formed by heating and pre-expanding in a mold from expandable polystyrene beads containing a volatile liquid foaming agent. The structural characteristics of holes are mainly used for building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, decoration and carving, etc. are very widely used. [0003] Because polystyrene is not easy to be decomposed, the original waste materials need to be decomposed and reprocessed in the production of the current polystyrene foam board, but the existing crushing device cannot crush the foam board more finely, so it will In the production process, it takes more time to dissolve polystyrene w...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a crushing and recycling protection device for polystyrene foam boards, which can detect the rotation speed of the crushing wheel in real time, and can slow down the crushing wheel when the rotation speed is too fast , The advantage of being able to quantitatively inject solvent into the device solves the problems that the speed of the grinding wheel cannot be detected, the speed of the grinding wheel cannot be slowed down when it rotates too fast, and the amount of injected solvent cannot be determined
