Spray feeder Spray feeder Stainless steel feeder Pneumatic conveying

Jet feeders, also known as Venturi jet compensators, produce adsorption and cause air flow when gas blows through a barrier and the pressure near the port above the leeward side of the barrier is relatively low. It reduces the gas flow from coarse to fine to accelerate the gas flow rate, so that the gas forms a vacuum area at the back of the Venturi tube outlet. When this vacuum zone is close to the workpiece, it will have a certain adsorption effect on the workpiece. High-pressure air enters through the venturi inlet and a small portion exits through a nozzle with a small cross-section. With the gradual reduction of the cross section, the pressure of the compressed air decreases and the flow rate increases. At this time, a vacuum degree is generated in the inlet of the adsorption chamber, causing the surrounding air to be sucked into the Venturi tube. With the compressed air flowing into the diffusion chamber, the flow rate of the gas is reduced, and then the airflow oscillation is reduced by the muffler.
 

Principle:

When gas blows through a barrier, the pressure near the port above the leeward side of the barrier is relatively low, resulting in adsorption and flow of air. The principle of Venturi tube is actually very simple, it is to change the gas flow from coarse to fine, so as to speed up the gas flow rate, so that the gas forms a vacuum zone at the back of Venturi tube outlet. When this vacuum zone is close to the workpiece, it will have a certain adsorption effect on the workpiece. High-pressure air enters through the venturi inlet and a small portion exits through a nozzle with a small cross-section. With the gradual reduction of the cross section, the pressure of the compressed air decreases and the flow rate increases. At this time, a vacuum degree is generated in the inlet of the adsorption chamber, causing the surrounding air to be sucked into the Venturi tube. With the compressed air flowing into the diffusion chamber, the flow rate of the gas is reduced, and then the airflow oscillation is reduced by the muffler.

Applications:

The injectors used in the ash and slag removal system of power plants usually use water as the conveying medium, that is, hydraulic injectors. Also known as hydraulic air extractors. Hydraulic ejector is used for hydraulic ash removal system, conveying ash slurry to ash pump front pool or dewatering bin. Its output is 30-50m3/h. nbsp;

Pros:
1)No moving parts, simple structure and small size;
2)The material receiving port is in the high negative pressure area, so the upper hopper can be in an open state, and the material can be continuously sucked;
3)After the diffusion pipe becomes positive pressure, dust removal equipment configuration is relatively simple;
