Description

Technical Field

[0001] This utility model relates to the field of powder drug dosing technology, specifically a detachable high-efficiency powder dosing jet. Background Technology

[0002] In the tap water or wastewater treatment industry, there are situations where it is necessary to add powdered agents such as activated carbon, potassium permanganate, and PAM in an emergency to remove pollutants, improve water quality, kill harmful microorganisms, accelerate the treatment process, or respond to emergencies. For example, powdered activated carbon can adsorb organic pollutants and residual chlorine in water, restoring the source water to its normal state. Flocculants and coagulants can enhance solid-liquid separation, promote the sedimentation and filtration of suspended solids, and improve treatment efficiency. These situations require the use of powder dosing equipment.

[0003] Chinese patent discloses an ejector device for ozone mixing (authorization announcement number CN221254124U). In this patented technology, the ejector tube includes an inlet section for connecting to the water inlet pipe and an ejector section connecting to the inlet section. An ozone inlet duct is located above and connected to the inlet section. A check valve is located in the ozone inlet duct. An internal interceptor is detachably located at the end of the inlet section away from the ejector section. A drain outlet is located below and connected to the inlet section. A guide plate extends obliquely from the inner wall of the inlet section toward the central axis of the inlet section. The ejector device is corrosion-resistant and anti-clogging, but it is inconvenient to disassemble, thus making it inconvenient to maintain. Utility Model Content

[0004] The purpose of this invention is to provide a detachable, high-efficiency powder feeding jet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A detachable high-efficiency powder dosing jet includes a mixing suction chamber, a throat tube embedded at one end of the mixing suction chamber, and a water inlet assembly embedded at the other end of the mixing suction chamber. A feed inlet is located at the upper end of the mixing suction chamber. A diffuser tube is located at one end of the throat tube. A Venturi jet nozzle is located on the inner side of the water inlet assembly near the throat tube, and a water inlet is located on the inner side of the water inlet assembly away from the throat tube. A mixing inlet is located on the inner side of the throat tube near the water inlet assembly, and a liquid outlet is located on the inner side of the diffuser tube away from the throat tube.

[0007] As a further embodiment of this invention: both the Venturi jet nozzle and the mixing inlet are located inside the mixing suction chamber, and the Venturi jet nozzle and the mixing inlet correspond to each other.

[0008] As a further embodiment of this utility model: the outer end of the mixing inhalation chamber away from the throat is connected to a first sealing flange by thread engagement, and the first sealing flange and the water inlet assembly are fixedly connected by fastening bolts.

[0009] As a further improvement of this invention, the mixing inhalation chamber and the larynx, as well as the larynx and the diffuser tube, are connected by threaded engagement.

[0010] As a further improvement of this utility model, the outer end of the diffuser tube away from the throat tube is connected to a second sealing flange by thread engagement.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this invention, the water inlet assembly, the first sealing flange, the throat, the diffuser, the mixing suction chamber, and the second sealing flange are all detachable, which facilitates the installation and maintenance of the jet ejector's interior.

[0013] The jet carrier is injected into the mixing and suction chamber through a Venturi jet nozzle, generating high-speed kinetic energy and shear force. The resulting strong negative pressure draws the powder material and air together from the feed inlet into the mixing and suction chamber 7, allowing the powder material and jet carrier to undergo preliminary mixing in the mixing and suction chamber. After further mixing in the throat and diffuser, a high-efficiency, low-energy-consumption jet-mixed drug solution with gas, solid, and liquid phases is formed, thereby achieving high-efficiency powder addition and effectively improving the utilization rate of powdered drugs.

[0016] Please see Figure 1In this embodiment of the present invention, a detachable high-efficiency powder dosing jet includes a mixing suction chamber 7. A throat 4 is embedded at one end of the mixing suction chamber 7, and a water inlet assembly 1 is embedded at the other end. An inlet 12 is located at the upper end of the mixing suction chamber 7. A diffuser 5 is located at one end of the throat 4. A Venturi jet nozzle 3 is located on the inner side of the water inlet assembly 1 near the throat 4, and a water inlet 11 is located on the inner side of the water inlet assembly 1 away from the throat 4. A mixing inlet 13 is located on the inner side of the throat 4 near the water inlet assembly 1, and an outlet is located on the inner side of the diffuser 5 away from the throat 4. The jet carrier (such as pressurized water) enters the water inlet assembly 1 through the inlet 11 and is sprayed into the mixing and suction chamber 7 through the venturi jet nozzle 3. The high-speed kinetic energy and shear force create a strong negative pressure that draws the powder material and air together from the feed inlet 12 into the mixing and suction chamber 7. This allows the powder material and the jet carrier to be initially mixed in the mixing and suction chamber 7. Then, the powder material enters the throat tube 4 and the diffuser tube 5 through the mixing inlet 13 in sequence. After further mixing, a high-efficiency, low-energy-consumption jet mixed liquid is formed in the gas-solid-liquid three-phase system. Finally, the liquid is discharged from the outlet 6 and transported to the set position, thereby achieving high-efficiency powder addition.

[0017] Preferably, the Venturi jet nozzle 3 and the mixing inlet 13 are both located inside the mixing suction chamber 7, and the Venturi jet nozzle 3 and the mixing inlet 13 correspond to each other. In this way, high-speed kinetic energy and shear force can be generated inside the mixing suction chamber 7 through the Venturi jet nozzle 3, and the powder material is mixed with the jet carrier and then sprayed into the mixing inlet 13.

[0018] Preferably, the outer end of the mixing suction chamber 7 away from the throat 4 is connected to a first sealing flange 2 by thread engagement. The first sealing flange 2 and the water inlet assembly 1 are fixedly connected by fastening bolts 9. The water inlet assembly 1 can be connected to the external jet carrier through the first sealing flange 2. When the fastening bolts 9 are loosened counterclockwise, the water inlet assembly 1 can be removed from the mixing suction chamber 7. Then, the first sealing flange 2 can be removed from the mixing suction chamber 7 by rotating it counterclockwise, which facilitates the installation and maintenance of the jet injector.

[0019] Preferably, the mixing chamber 7 and the throat tube 4, as well as the throat tube 4 and the diffuser tube 5, are connected by threaded engagement, so that the throat tube 4 can be removed from the mixing chamber 7, and the diffuser tube 5 can be removed from the throat tube 4, thereby facilitating the installation and maintenance of the jet injector.

[0020] Preferably, the outer end of the diffuser tube 5 away from the throat tube 4 is connected to a second sealing flange 8 by thread engagement. The second sealing flange 8 is connected to the external liquid outlet pipe, so that the medicine solution that is uniformly mixed in the diffuser tube 5 can be delivered to the set position through the liquid outlet pipe.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
