A method for manufacturing a primary filter mechanism and a quartz glass purification device

Abstract

The invention provides a primary filtering device which has high purity after purification, cannot produce secondary pollution in a manufacturing process and is high in airtightness after manufacturing is finished, a manufacturing method of the primary filtering device and a quartz glass purifying device. A primary filtering mechanism comprises a first filter body communicated with a material storage mechanism as well as a plurality of sieve plates which are arranged in the first filter body. The quartz glass purifying device comprises a material storage mechanism, a primary filtering mechanism communicated with the material storage mechanism, a secondary filtering mechanism communicated with the primary filtering mechanism and a condensing mechanism communicated with the secondary filtering mechanism. The primary filtering device, the manufacturing method of the primary filtering device and the quartz glass purifying device which are provided by the invention have the advantages that the purification degree is high, the yield is high, the pollution is slight and the airtightness is good.

Description

technical field [0001] The invention relates to the field of purification of chemical raw materials, in particular to a primary filter device, a manufacturing method and a quartz glass purification device. Background technique [0002] Quartz glass is an important new material of modern science and technology, providing a large number of key materials for high-tech fields such as electric light source, electronics, laser and aerospace; [0003] In the prior art, chemical raw material purification equipment made of quartz glass is generally designed with a packing type, which not only has low purity of raw material purification, but also has high pollution; [0004] Moreover, during the manufacturing process of the equipment, the components are manufactured by manual welding, and manual welding is more difficult. The main disadvantages are: [0005] 1. The purified product requires high purity, and the secondary pollution caused by manual welding needs to be overcome during ...

AI Technical Summary

Problems solved by technology

[0006] 2. Due to the large overall size of the equipment, it is difficult to ensure the verticality by manual welding;

[0007] 3. Since the interface is directly welded with electrodes, the thickness of the interface is uneven, and it is easy to leak air after long-term use;

[0008] 4. Direct welding, the quartz surface is easy to be polluted, which affects the precision of liquid purification;

[0009] 5. It is easy to burst during manual welding;

[0010] 6. The manual welding time is long, the product is in direct contact with the flame, it is easy to cause crystallization, the product cleanliness is not enough, and the product purity is affected
