Description

Detachable high efficiency powder throws and adds ejector Technical Field The utility model relates to the technical field of powder medicament adding, in particular to a detachable high-efficiency powder adding ejector. Background In the tap water or sewage treatment industry, powder medicaments like active carbon, potassium permanganate, PAM and the like are needed to be added in an emergency, so as to remove pollutants, improve water quality, kill harmful microorganisms, accelerate the treatment process or cope with emergency, for example, the powder active carbon can absorb organic pollutants and residual chlorine in water, recover the normal state of source water, and the flocculant and coagulant aid can strengthen solid-liquid separation, promote the precipitation and filtration of suspended matters and improve the treatment efficiency, so that powder throwing equipment is needed. Chinese patent discloses a jet device for ozone mixing (grant bulletin number CN 221254124U), in which the jet pipe includes an inflow section for connecting with a water inlet pipe and a jet section connected with the inflow section, an ozone introducing air passage is provided above the inflow section and is communicated with the inflow section, a check valve is provided in the ozone introducing air passage, a built-in interception net is detachably provided at one end of the inflow section away from the jet section, a sewage drain is provided below the inflow section and is communicated with the inflow section, and a guide plate extends from the inner wall of the inflow section obliquely toward the central axis of the inflow section, and the jet device is corrosion-resistant and anti-blocking, but is inconvenient to detach, thereby being inconvenient to overhaul. Disclosure of utility model The utility model aims to provide a detachable high-efficiency powder feeding ejector so as to solve the problems in the background technology. In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a detachable high efficiency powder throws and adds ejector, is including mixing the suction chamber, the one end embedding of mixing the suction chamber is provided with the choke, and is provided with the subassembly of intaking at the other end embedding of mixing the suction chamber, the upper end of mixing the suction chamber is provided with the feed inlet, the one end of choke is provided with the diffuser, the inboard that is close to the choke of subassembly of intaking is provided with venturi jet nozzle, and the inboard that the choke was kept away from to the inboard of subassembly of intaking is provided with the water inlet, the inboard that is close to the one end of intaking the subassembly of choke is provided with the mixing inlet, the inboard that the choke was kept away from to the inboard of diffuser is provided with the liquid outlet. As a still further proposal of the utility model, the venturi jet nozzle and the mixing inlet are both positioned in the mixing suction chamber, and the venturi jet nozzle corresponds to the mixing inlet. As a still further scheme of the utility model, one end of the outer side of the mixing suction chamber, which is far away from the throat pipe, is connected with a first sealing flange in a threaded engagement manner, and the first sealing flange is fixedly connected with the water inlet component through a fastening bolt. As a still further proposal of the utility model, the mixing suction chamber is connected with the throat pipe and the throat pipe is connected with the diffuser pipe through screw thread engagement. As a still further proposal of the utility model, one end of the outer side of the diffuser pipe far away from the throat pipe is connected with a second sealing flange through threaded engagement. Compared with the prior art, the utility model has the beneficial effects that: The water inlet component, the first sealing flange, the throat pipe, the diffuser pipe, the mixing suction chamber and the second sealing flange can be detached, so that the installation and the overhaul of the inside of the ejector are convenient; The jet carrier is sprayed into the mixing suction chamber through the Venturi jet nozzle, high-speed kinetic energy and shearing force are formed, the powder material and air are sucked into the mixing suction chamber 7 together from the feeding port under the strong negative pressure caused by the high-speed kinetic energy and shearing force, the powder material and the jet carrier are initially mixed in the mixing suction chamber, and then enter into the throat and the diffuser pipe for further mixing in sequence, so that the jet mixed liquid medicine with high efficiency, low energy consumption of gas, solid and liquid phases is formed, the powder is further fed in high efficiency, and the utilization rate of the powder medicament can be effectively improved.
