Pearlite transfer and filling device and method for oxygen station refrigerator

Abstract

The invention provides a pearlite transfer and filling device for an oxygen station refrigerator and a method. The device comprises a three-dimensional refrigerator; the top end of the refrigerator is an opening structure; a funnel is mounted; a transmission system is arranged above the funnel, and includes a transportation belt, a power system and a belt bracket system, wherein the transportation belt is aslant arranged, the bottom end of the transportation belt is connected with the pearlite filling device, and the top end of the transportation belt is aligned to the funnel; multiple transportation hoppers are arranged on the surface of the transportation belt at equal intervals; the transportation hoppers are of semi-closed structures, and are provided with baffle plates at the tops; and a guide pipe extends from the bottom of the funnel into an appointed position in the refrigerator. The invention further discloses a method adopting the device to operate. The device is simple in structure, is safe and efficient in pearlite transfer process, reduces the staff operation intensity, improves the working efficiency, reduces the safety risk, reduces the intermediate link of aerial pearlite filling, reduces the pollution, and facilitates environmental protection.

Description

technical field [0001] The invention relates to the field of pearlite sand transfer and filling technology, in particular to a pearlite sand transfer and filling device and method for an oxygen station cold box. Background technique [0002] Pearlescent sand, also known as expanded perlite, is a kind of material with a honeycomb structure inside and a white spherical loose granular material formed by vitreous lava after crushing and high-temperature combustion expansion. It is colorless, odorless, sound-absorbing, non-combustible, and non-corrosive. It is widely used due to its extremely low thermal conductivity, reliable chemical stability, good filling fluidity and extremely low bulk density. Especially in cryogenic engineering and air separation equipment as a thermal insulation material, it is irreplaceable by other substances. [0003] Since pearlite is a particle with low density and good fluidity, it is easy to fly, invade the five sense organs, cause sore eyes, thr...

AI Technical Summary

Problems solved by technology

[0004] In the oxygen station project, the filling volume of pearlite in the cold box is very large, and often hundreds of tons (thousands of m3) are needed. Using conventional winches, cranes and manual cooperation to transfer to the top of the cold box is very heavy, and the construction efficiency is low. Higher cost and greater risk
