High-precision low-temperature crushing device for production of glass substrate frame

Abstract

The invention discloses a high-precision low-temperature crushing device for production of a glass substrate frame. The high-precision low-temperature crushing device comprises a feeding drum, a coarse material crushing drum, a fine material crushing drum and cooling drums, wherein tapered material distribution trays are connected with and arranged at the bottom end of the feeding drum; a plurality of parallel crushing rollers are uniformly arranged in the interior of the coarse material crushing drum at equal intervals; air inlet pipes are respectively connected with and arranged on the sidesurfaces of the fine material crushing drum; external air compressed by air compressors is sucked into the fine material crushing drum by the air inlet pipes; the air outlet end of each air inlet pipeis provided with a metal air outlet seat; the inner wall of each cooling drum is provided with heat conducting plates which are in connection through connecting plates; a heat-dissipating groove is arranged between the connecting plates and each cooling drum; the interior of each heat-dissipating groove is provided with a communicating pipe; a liquid nitrogen drum is connected with and arranged at the external end of each communicating pipe; a hollow cooling seat is connected with and arranged at the bottom end of each liquid nitrogen drum; and each air inlet pipe penetrates through and is connected with a hollow cooling seat. Thus, through combination of multiple crushing manners, the high-precision low-temperature crushing device provided by the invention realizes high-precision low-temperature crushing, cools an air flow used for crushing at the same time, and improves the quality of low-temperature crushing.

Description

technical field [0001] The invention relates to the technical field of crushing, in particular to a high-precision low-temperature crushing device used for the production of glass substrate frames. Background technique [0002] In the production of glass substrate racks, the raw materials need to be pulverized first in order to achieve better production quality, and in the pulverization process, the specific temperature needs to be controlled so as not to affect the final product due to the high temperature during the pulverization process quality. This is because the temperature of the production system will directly affect the quality and production efficiency of the product. Due to the different performance and forming process requirements of various glass substrate racks, the requirements for the crushing environment are also different. For most glass substrates with lower requirements The frame can only be crushed directly, but for the glass substrate frame with high q...

Problems solved by technology

[0004] However, the general low-temperature pulverization device only adopts single-time pulverization, which cannot achieve the required pulverization accuracy. At the same time, the heat in the pulverization process cannot be removed in time, which is not conducive to the realization of low-temperature pulverization.
