Abstract

The invention relates to a venturi treatment powder pump for tangentially feeding powder, which comprises a powder pump body. The powder pump is provided with a powder input channel, a venturi tube, a pump cavity and an airflow input channel; the tail of the venturi tube is arranged in the pump cavity; an air-powder mixture inlet is arranged at the tail of the venturi tube, and an air-powder mixture outlet is arranged at the front end of the venturi tube; a nozzle is arranged at the right rear of the air-powder mixture inlet and the middle of a rear bottom wall of the pump cavity; the nozzle is arranged at the tail end of the airflow input channel; and a powder outlet which is located at the end of the airflow input channel is arranged at the side wall of the pump cavity. The venturi treatment powder pump is characterized in that the pump cavity is a circular cross section; and a powder feeding direction of the powder outlet is tangent to the side wall of the pump cavity. The powder is sprinkled to the pump cavity like a spiral line shape; compressed air brought by the nozzle provides a negative pressure for the powder and meanwhile plays a role of stirring, so that the powder is mixed better; and abrasion of the powder to a tube wall is small, service life of parts is prolonged, and working is high-efficient and reliable.

But there is following shortcoming in its structure of venturi powder pump of using now: such as Fig. 2, shown in Figure 3, powder input channel 44 be positioned at pump inner chamber 45 belows, the two ends of powder input channel 44 arrange respectively powder input port 47 and powder delivery outlet 46, powder delivery outlet 46 powder feeding perpendicular directions intersect at the air-flow of nozzle 43 outputs, cause powder 2 at the close tube wall of Venturi tube 5 interior meetings, compressed air can be near Venturi tube 5 centers, it is inhomogeneous that the gas powder mixes, and 2 pairs of powder inner chambers 44 of powder, Venturi tube 5 inner wall abrasion are fast.

3, summary of the invention

The object of the present invention is to provide a kind of venturi powder pump that tangentially advances powder, it is more even that it can make the gas powder mix, and reduces pressure-air to pump inner chamber and Venturi tube inner wall abrasion, increases the service life, and efficient work is reliable.

The present invention by following technical solution scheme realizes:

A kind of venturi powder pump that tangentially advances powder, it comprises the powder pump housing, this powder pump housing has a powder input channel, Venturi tube, pump inner chamber and air-flow input channel, the afterbody of Venturi tube is installed in pump inner chamber the inside, the afterbody of Venturi tube is provided with gas powder mixture entrance, front end arranges the outlet of gas powder mixture, dead astern at gas powder mixture entrance, the middle part of the rear diapire of pump inner chamber is equipped with nozzle, nozzle is installed in the end of air-flow input channel, the powder delivery outlet that is positioned at powder input channel end is arranged on the sidewall of pump inner chamber, the pump inner chamber is circular cross-section, and the powder feeding direction of powder delivery outlet and the sidewall of pump inner chamber are tangent.

Powder input channel described above and the sidewall of pump inner chamber are tangent.

Powder input channel described above is vertical bar shaped passage from lower to upper.

Powder delivery outlet described above has a plurality of, along the pump lumen shaft to spaced apart.

The present invention compared with prior art has following advantage: 1, the pump inner chamber is circular cross-section, the powder feeding direction of powder delivery outlet and the sidewall of pump inner chamber are tangent, the quilt that powder resembles zigzag shape spills to pump housing inner chamber, when the compressed air of being introduced by nozzle provides negative pressure to powder powder there is a stirring, make powder obtain better to mix, then be transferred away from the outlet of gas powder mixture.Gas powder mixture everywhere mixed proportion in pump housing inner chamber, Venturi tube is substantially suitable, can not form powder in the outer part and air-flow by the phenomenon at center, powder is little to transducer wall ' s abrasion, prolongs part service life, efficient work is reliable; 2, the sidewall of whole powder input channel and pump inner chamber is tangent, simple in structure, handling ease; 3) the powder delivery outlet has a plurality ofly, along the pump lumen shaft to spaced apart, can regulate like this mixed proportion of gas powder mixture.
