Description

Technical Field

[0001] The utility model relates to the technical field of ejector equipment, in particular to a rotating ejector core. Background Art

[0002] Existing ejectors mostly adopt the Venturi structure, also called Venturi mixer, which consists of three parts: nozzle, suction chamber and diffuser. The working fluid with a certain pressure is ejected at high speed through the nozzle, so that the pressure energy is converted into velocity energy, and a vacuum is formed in the nozzle outlet area, thereby sucking out the pumped medium. The two streams of medium are mixed and exchanged with energy in the diffuser, and the velocity energy is restored to pressure energy, and finally discharged at a pressure higher than the atmospheric pressure.

[0003] The mixing effect or energy exchange effect of the ejector is related to the selection of the ejector model, that is, the suction pressure corresponding to the model. If different suction pressures are required, enhanced or weakened, to achieve ejectors with different mixing effects or energy exchange effects, it is necessary to prepare multiple models of ejectors with multiple suction pressures, which increases the equipment cost for the enterprise. Therefore, the existing ejectors need to be improved. Utility Model Content

[0004] The utility model aims to provide a rotary jet core with adjustable suction of the pumping medium and high practicality, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A rotating jet core, comprising an ejector swirl core located in an ejector nozzle, the ejector swirl core comprising a connecting end and a cylindrical body guide, a plurality of spaced connecting bodies are arranged between the connecting end and the body guide, an external thread is arranged on the outer side of the connecting end, and an internal thread connected to the external thread is arranged at the water inlet of the ejector nozzle;

[0007] A fluid passage is provided inside the connecting end portion for allowing fluid to pass through, the fluid passage being connected to an external water pipe and a suction chamber, a plurality of fluid passages are provided on the outer circumferential side surface of the guiding body and are symmetrical along the axis of the guiding body, and the fluid passage is in a longitudinal arc structure from one end close to the connecting end portion to the other end; the connector corresponds to the position of the fluid passage, and a buffer arc groove is provided at the end face of the connecting end portion close to the guiding body and corresponding to the position of the fluid passage, the fluid passage is in a longitudinal arc shape, and the offset angle is 3-5°.

[0008] The outer side surface of the circumference of the guide body is provided with a plurality of fluid passages symmetrically along the axis of the guide body. The fluid passage is replaced by a longitudinal arc structure from one end close to the connection end to the other end. The outer side surface of the circumference of the guide body is provided with a plurality of guide plates with a longitudinal arc structure. The guide plates are symmetrically arranged about the axis of the guide body, and fluid passages are formed between the guide plates. The guide plates are longitudinally arc-shaped, and the offset angle is 3-5°.

[0009] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0010] The utility model adds an ejector swirl core which is easy to disassemble in the ejector. If ordinary medium suction pressure is required, it is not installed, and if the suction pressure needs to be further increased, it is installed. Compared with the prior art, an ejector and an ejector swirl core located inside are matched with each other to realize suction pressure adjustment. The whole design is very clever and more practical.

[0011] The structure of the ejector swirl core is also relatively simple. It only uses a fluid passage that is symmetrical along the centerline of the guide body axis. The fluid passage is a longitudinal arc structure from one end close to the connecting end to the other end. Due to the guidance of the fluid passage, the speed will gradually increase, changing the flow direction of the incoming fluid, and a flow similar to a vortex will be generated. This rotational motion makes the outflowing water flow more dispersed and increases the surface area. If used for mixing, it further increases the mixing effect with the liquid drawn into the ejector. If used for vacuuming, the gas in the container can be extracted faster.

The fluid channel 10 is in a longitudinal arc shape with an offset angle of 3-5°. Example 2

[0025] When it is necessary to increase the suction pressure, that is, to improve the mixing effect or the vacuuming effect, the ejector swirl core is installed in the nozzle of the ejector, and they are threadedly connected for easy disassembly. Then the fluid flows into the fluid channel from the liquid inlet end of the ejector, and then flows out from between the connecting end 4 and the body guide 5.

If used for vacuuming, it can extract the gas in its container faster.
