Raw material classifying and transporting device for thermal insulation material manufacturing

Abstract

The invention discloses a raw material classifying and transporting device for thermal insulation material manufacturing. The raw material classifying and transporting device comprises a base, supporting legs distributed in a rectangular shape are fixedly connected to the outer wall of the top of the base, a shell is fixedly connected to the outer walls of the tops of the supporting legs, a dust collection box is fixedly connected to the outer wall of the top of the shell, and a draught fan is fixedly connected to the outer wall of one side of the dust collection box; the input end of the draught fan communicates with the dust collection box, a first mounting hole is formed in the inner wall of the bottom of the dust collection box, an air pipe is fixedly connected to the inner wall of thefirst mounting hole, and a dust collection disc is fixedly connected to one end of the air pipe; and a filter screen is arranged on the inner wall of the dust collection box. According to the raw material classifying and transporting device, through arranging the draught fan, air in the dust collection box can be exhausted through the draught fan, so that the interior of the dust collection box is in a negative pressure state, the dust collection disc can generate suction force, crushed raw materials can be subjected to dust collection, and the influence on people and the environment during transportation of the raw materials is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of sorting and transporting devices, in particular to a raw material sorting and transporting device for manufacturing thermal insulation materials. Background technique [0002] The traditional thermal insulation materials are mainly to increase the gas phase void ratio and reduce the thermal conductivity and conductivity coefficient. In order to increase convective heat transfer and radiation heat transfer in the use environment, fiber-based thermal insulation materials must have a thicker coating; while profile-based inorganic thermal insulation materials need to be assembled and constructed, there are many seams, which damage the appearance and waterproof. Poor performance, short service life and other defects. [0003] Expanded perlite is a natural acidic vitreous volcanic lava, a non-metallic mineral, which can be used as a high-efficiency thermal insulation and cold insulation filling material. After...

Problems solved by technology

In order to increase convective heat transfer and radiation heat transfer in the use environment, fiber-based thermal insulation materials must have a thicker coating; while profile-based inorganic thermal insulation materials need to be assembled and constructed, there are many seams, which damage the appearance and waterproof. Defects such as poor performance and short service life

[0003] Expanded perlite is a natural acidic vitreous volcanic lava, a non-metallic mineral, which can be used as a high-efficiency thermal insulation and cold insulation filling material. After being mined from the mine, it needs to be mechanically crushed and then processed into ore sand with a certain particle size distribution. After crushing, it needs For classified transportation, the traditional classification transportation device cannot remove dust from the crushed raw materials, which will affect people and the environment during transportation.
