Gas distribution device for medical treatment

Abstract

The invention discloses a gas distribution device for medical treatment, which comprises a mounting plate and an air hole. A circle of vertically arranged first connecting rods is arranged on the mounting plate, and horizontally arranged connecting rods are connected between the first connecting rods. The second connecting rod, the second connecting rod is provided with multiple sets of vertically arranged fixed rods, the fixed rods are connected with the telescopic rods, one end of the telescopic rods is connected with the anti-blocking kit, and the anti-blocking The kit is provided with a first purge pipe with an opening downward, and the upper end of the anti-blocking kit is provided with a second purge pipe which is arranged obliquely. Purge to prevent the accumulation and agglomeration of particles around the air hole, and avoid the occurrence of air hole blockage. When it is not in use, the anti-blocking kit is connected to the air hole to prevent particles from slipping in and the air hole is blocked by particles.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a gas distribution device for medical treatment. Background technique [0002] In the fluidized bed production process, the gas distribution plate is an important component to ensure a good and stable fluidized state of the gas-solid fluidized bed, which directly affects the flow pattern and fluidized uniformity of the particles in the fluidized bed. The key components that must be considered in reactor design, the gas distribution plate determines the frequency of bubble generation and the initial state of gas-solid contact, and the internal components directly affect the entire flow state. In the prior art, the distribution plate of the fluidized bed inside the reactor is in the shape of a circular flat plate, a circular truncated distribution plate, and a funnel-shaped inverted conical structure. During use, the distribution plate is often blocked, resulting in fluidiz...

AI Technical Summary

Problems solved by technology

In the prior art, the distribution plate of the fluidized bed inside the reactor is in the shape of a circular flat plate, a circular truncated distribution plate, and a funnel-shaped inverted conical structure. During use, the distribution plate is often blocked, resulting in fluidization. The state is poor, which affects the yield of the reaction and increases the production cost. When the distribution plate is seriously blocked, it is necessary to stop the machine and manually clean the distribution plate. The cleaning process is time-consuming and labor-intensive, and there is a certain degree of danger.
