Description

Technical Field

[0001] The utility model belongs to the technical field of gas distributors, in particular to a gas distributor. Background Art

[0002] There are many types and structural forms of gas distributors. Their function is to evenly distribute gas. They are widely used in the chemical industry, such as in fermentation tanks.

[0003] At present, the gas distributor of the fermentation tank has some shortcomings, such as its gas distribution area is small, and the gas distribution area needs to be improved; when the tube body is flushed after use, it is easy to accumulate material residue, which will breed bacteria, affect the next use or cause a certain degree of pollution to the next material; the gas distributor is generally an integrated structure, and since the tank mouth of the tank body is generally much smaller than the diameter of the tank body, the gas distributor needs to be installed after entering from the tank mouth, so the volume of the gas distributor cannot be too large, which will also affect the distribution of the gas to a certain extent. Utility Model Content

[0004] The utility model provides a gas distributor which can solve the problems pointed out in the background technology.

[0005] A gas distributor comprises a shell, an air inlet end and a plurality of air outlet holes, wherein the shell comprises a top surface body and a bottom surface body, the top surface body is a conical body, the plurality of air outlet holes are evenly distributed on the top surface body, the air outlet holes are all connected to an air guide pipe, and the air guide pipe comprises a straight pipe at the bottom and an inclined pipe at the top.

[0006] Preferably, the top surface body is an arc body.

[0007] Preferably, an air outlet gap is provided between the top surface body and the bottom surface body, and the bottom surface body has a discharge slope.

[0008] Preferably, the cross-section of the bottom body is conical or arc-shaped.

[0009] Preferably, a circle of air outlet gap is provided between the top surface body and the bottom surface body, and the top surface body and the bottom surface body are connected via a plurality of connecting seats, and the connecting seats are provided with connecting grooves.

[0010] Preferably, the shell is composed of at least two halves.

[0011] Beneficial effects: The utility model provides a gas distributor having the following advantages:

[0012] The conical top surface or the arc top surface enables the ejected airflow to be spread in a "trumpet shape", thus expanding the gas distribution area;

[0013] An air guide pipe with an inclined tube on the upper part is provided so that the ejected airflow can flow in a "spiral shape", thereby expanding the gas distribution area and performing a certain spiral stirring on the material, thereby improving the stirring effect;

[0014] The air outlet gap is set to spray air in the radial direction, expanding the distribution range of the gas. In addition, when cleaning, the residual slag flows out from the air outlet gap. Combined with the discharge slope, the discharge can be as clean as possible, effectively avoiding bacterial growth;

[0015] The shell is composed of at least two halves, which is convenient for entering through the tank opening and allows the gas distributor to be designed to have a larger volume. BRIEF DESCRIPTION OF THE DRAWINGS
