[0021] Specifically, the installation process of the cluster jet mixer of the present invention is as follows: first, insert the nozzle 11 into the first through hole 8, and fix the nozzle 11 on the first blind flange 6 with a bolt, and the bolt head is immersed in the first threaded countersunk hole 13. Then, the first annular boss 12 on the nozzle 11 is corresponding to the first annular groove 21 on the water inlet pipe body 2 and plugged together. At this time, the third through hole 20 corresponds to the inlet of the nozzle 11. Then, the first blind flange 6 and the third blind flange 19 are bolted together. Then, insert the throat 14 into the second through hole 9 and fix the throat 14 on the second blind flange 7 with a bolt, and the bolt head is immersed in the second threaded countersunk hole 16. Then, one end of the throat 14 is inserted into the fourth through hole 25 on the water outlet pipe body 3 until the second annular boss 15 on the throat 14 is inserted into the second annular groove 26 on the water outlet pipe body 3. Finally, the second blind flange 7 and the fourth blind flange 24 are bolted together. At this point, the entire cluster jet mixer is installed.

[0022] Furthermore, the ejector tube 4 is welded on the mixing chamber body 1 and is connected to the mixing chamber 5 . When a negative pressure is formed in the mixing chamber 5 , the gas, liquid or solid to be ejected will enter the mixing chamber 5 through the ejector tube 4 .

[0027] Furthermore, the nozzle 11 and the throat 14 are made of stainless steel or polyethylene, which has good acid and alkali resistance, good anti-corrosion effect, and can extend the service life.

[0028] This jet mixer adopts the principle of Venturi tube, with pressurized water flow as the incident fluid entering the mixing chamber through the water inlet pipe body, and forming negative pressure in the mixing chamber, and continuously drawing the gas, liquid or solid into the mixing chamber through the ejector pipe for uniform mixing, and then discharged from the water outlet of the water outlet pipe body to the dosing point. The bundled jet mixer of the utility model greatly improves the jet ejection specific surface area and the ejection efficiency by installing multiple nozzles and throat pipes while ensuring the ejection, dispersion, mixing and conveying capabilities of the jet mixer; in addition, by arranging the first through hole and the second through hole relative to each other, and setting the first through hole The aperture of the hole is the same as the outer diameter of the nozzle, and the aperture of the second through hole is the same as the outer diameter of the throat, which ensures that the center points of the nozzle and the throat are located on the same central axis, thereby improving the precision of the jet mixer. At the same time, when the nozzle and the throat are fixed, a countersunk structure is adopted, and the connecting bolts are located in the countersunk holes. When the water inlet pipe body and the water outlet pipe body are flange-connected to the mixing chamber pipe body, the annular bosses on the nozzle and the throat are located in the annular groove, and the annular bosses are clamped and pressed, so that the pressure at the connection between the nozzle and the throat is diffused to the entire structure, effectively preventing the structural deformation and offset caused by the pressure of the bolts, and extending the service life of the equipment.
