Abstract

The utility model relates to a water jet suction apparatus, belonging to the vacuum technology of fluid jet. The utility model is composed of a water inlet, a nozzle, a mixing chamber, a pressure water chamber, a suction opening, an annular nozzle, a converging pipe and a diffusion pipe. The utility model is characterized in that the pressure water chamber (5) is additionally arranged on the periphery of the converging pipe (9), and the pressure water chamber (5) is transited with the diffusion pipe (10) by a circular arc, the circular arc transition place and the converging pipe (9) form the annular nozzle (7), water in the pressure water chamber (5) is sprayed onto an inner wall of the diffusion pipe (10) from the annular nozzle (7), and a layer of high-speed circular water flow is attached to a wall of the diffusion pipe. The layer of the flow causes the kinetic energy of high-speed gas-water to be changed into potential energy in the diffusion pipe. The utility model reduces energy loss and achieves the goal of energy saving.

Description

Water jet air ejector

The utility model relates to the fluid jet vacuum technique, particularly a kind of water jet air ejector.

Water jet air ejector is to spray from nozzle with press water in the prior art, in mixing chamber with the air mixing of certain vacuum degree, through convergence pipe, throat, diffusing tube, enter atmosphere at last, its energy is lost in the kinetic energy that the air-water mixture that flows out at a high speed diffusing tube is taken away mostly, next is the energy consumption that rubs and produced between the emitted water of nozzle and the energy loss that restrains pipe collision generation and water and the tube wall, and therefore, efficient is low especially.

The purpose of this utility model is: a kind of annular nozzle (7) of setting up above diffusing tube is provided, make the diffusing tube inwall add one deck high speed ring-type current, impel the kinetic energy of air-water mixture in diffusing tube, to change potential energy into, reduce energy loss, reach purpose of energy saving.

Formation of the present utility model: by water intake, nozzle, mixing chamber, the pressure hydroecium, bleeding point, annular nozzle, the convergence pipe, diffusing tube is formed, in the top of pressure hydroecium (3) is water intake (1), the below is nozzle (2), the below of nozzle (2) is mixing chamber (4), mixing chamber-side has bleeding point (6), the below is a convergence pipe (9), the below of convergence pipe (9) is diffusing tube (10), on the circumference of convergence pipe (9), pressure hydroecium (5) is arranged, pressure hydroecium (5) lower end and diffusing tube (10) top are arc transition, the lower end circumferential of arc transition place and convergence pipe (9) is nozzle (7) circlewise, and a side of pressure hydroecium (5) has water intake (8).

Compared with the prior art, the utility model is simple in structure, volume is little, good energy-conserving effect, and higher efficient is all arranged from the rough vacuum to the high vacuum.

Accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is accompanying drawing 1 annular nozzle enlarged views.

Embodiment of the present utility model: as shown in Figure 1, pressure hydroecium (3) top is a water 1 (1) into, the below is nozzle (2), the below of nozzle is mixing chamber (4), mixing chamber (4) one sides have bleeding point (6), and below convergence pipe (9) is pressure hydroecium (5) on the circumference of convergence pipe, pressure hydroecium (5) and convergence pipe (9) lower end form annular nozzle (7), the little head end of conical diffusing tube (10) and pressure hydroecium (5) arc transition.During work, press water enters pressure hydroecium (3) and (5) from water intake (1) and (8), and the water that enters pressure hydroecium (3) enters mixing chamber (4) from nozzle (2), with the air mixing of certain vacuum degree, and enters diffusing tube (10) through convergence pipe (9).The water that enters pressure hydroecium (5) enters diffusing tube (10) from annular nozzle (7) along tube wall, makes the diffusion tube wall adhere to one deck high speed ring-type current, and this layer current directly do not contact the high speed air-water mixture with the diffusion tube wall, can reduce energy loss.
