Thermal-insulation microsphere particle grading device

Abstract

The invention discloses a thermal-insulation microsphere particle grading device. The device is characterized in that a grading channel is provided with at least two levels of vertically arranged turning channels, the front and rear side walls of the turning channels are aligned to the front and rear edges of receiving hoppers respectively, each of the left side wall and the right side wall of each turning channel is formed by connecting vertical upper sections and lower sections inclined leftwards, air outlets are formed in the connection positions of the upper sections and the lower sections of the left side wall of each turning channel, air inlets are formed in the connection positions of the upper sections and the lower sections of the right side wall of each turning channel, horizontal air pipes are connected to the air inlets and connected with a fan or a compressed air tank, lower edges of the left and right side walls of the bottommost turning channel are aligned to the left and right edges of receiving hopper groups, the upper edge of the turning channel at the lower part is connected with the lower edge of the turning channel at the upper part, and a falling hopper is connected with the upper edge of the topmost turning channel through a conical cover and is provided with a falling channel having the same width as the inside dimension of the front and rear part of the turning channel. The thermal-insulation microsphere particle grading device can realize grading, can realize one-time multi-grade separation, is high in efficiency and can remove dust.

[0002] In the field of construction, thermal insulation boards as thermal insulation materials are constantly being updated with the advancement of technology. Thermal insulation boards based on vitrified microbeads have gradually become the market leader due to their excellent characteristics. Vitrified microbeads are made of ore in an electric furnace Puffing occurs under the heating method, the surface of the particles melts and the pores are vitrified and closed, the gloss is smooth, and the interior is a porous cavity structure, which has the advantages of light weight, heat insulation, fire prevention, high strength, low water absorption, etc., and the physical and chemical properties are very stable, and the service life is long. , is very suitable as a lightweight aggregate for insulation boards in the new building materials industry. During production, vitrified microbeads are mixed with adhesives, etc., and then pressed to form insulation boards with excellent performance; due to the size of vitrified microbeads It is not uniform. Under the influence of transport and vibration, the vitrified microbeads are easy to stratify according to the particle size, which will cause the uneven distribution of the size particles in the insulation board and affect the quality of the insulation board. In order to make the particles For uniform distribution, different particles are generally mixed together before production, which involves size grading of vitrified microbeads. There are still relatively few equipment in this regard, and these still need to be solved technically.
