Abstract

The utility model relates to the heating equipment, and in particular relates to a pipeline type steam and water mixer. The steam and water mixer is mounted on a hot water pipeline, and comprises a hot water inlet at one end of the shell, wherein the side face of the steam and water mixer is a steam inlet, and the other end of the steam and water mixer is an outlet; in the shell, the left end, the right end and the middle are provided with ring-type locating plates, insertion bars are inserted among the locating plates, and the insertion bars are radially distributed in a ring form along the locating plates and form an angle of inclination. The steam and water mixer has the advantages of using loose joints, being convenient to install and disassemble, being wide in application range, being excellent in steam and water mixing effect, having fewer components and being more healthful.

Description

Steam heater

Technical field

The utility model relates to firing equipment, particularly a kind of duct type steam heater.

Background technology

The duct type steam heater is a kind of direct-type firing equipment on pipeline that is installed in, and has the characteristics such as the thermal efficiency is high, noise is low, installation simply, does not take up space, and is widely used in heating system in heating, air-conditioning.

Traditional steam heater core component mostly is Rafael nozzle, and current fully mix rear outflow with the steam that sprays into from inclined hole, are filled with metal packing in housing, eliminates noise.Blender improves mostly to be the filler between its shell and jet pipe is improved, as CN90215997, filling be the unordered stainless steel filament of a certain amount of arrangement.201010579191.3 1 kinds of steam water mixed heating devices and for example, comprise a carbonated drink heating clamber, be respectively equipped with water inlet pipe, air inlet pipe and outlet pipe with flange on the locular wall of this carbonated drink heating clamber, be provided with a convergent jet pipe in water inlet pipe, be provided with a mixing tube in outlet pipe, be provided with the hybrid chamber with the taper import in the body of this mixing tube, the outlet of convergent jet pipe is positioned at the taper import of mixing tube, and the inner tubal wall of the outer tube wall of its convergent nozzle exit and the import of mixing tube taper consists of a ring-type daraf(reciprocal of farad) that de Laval noz(zle).Healed water sprays after the decompression of convergent jet pipe, acceleration and enters mixing tube, vapor stream adiabatic expansion in your de Laval noz(zle) of ring-type daraf(reciprocal of farad) enters in mixing tube with the supersonic speed ejection, sharply mix with healed water and emit the latent heat of vaporization and be condensed into water, healed water absorbs the latent heat of vaporization and heats up.

In prior art, if steam heater is connected to the words of sterilization machine, the sanitary conditions of steam heater there is higher requirement, particularly wherein filler can make health often not reach index, therefore how to make the structure in steam heater few, and can reach the effect of steam-water mixing, be a problem that faces at present.

The utility model content

Technical problem to be solved in the utility model is: a kind of steam heater is provided.

The utility model solves described a kind of steam heater by following proposal, be loaded on the hot water line, can connect sterilization machine, comprise the hot water inlet that is positioned at shell one end, the steam inlet of side, the other end is outlet, in described shell, left and right two ends and medium position are provided with ring-like spacer, are inserted with cutting between described spacer, and described cutting is radial annular spread and forms the inclination angle along spacer.After hot water enters steam heater from hot water inlet, pass through from the shell center; And steam enters steam heater from the steam inlet of side direction, after running into described cutting, enters the shell center between the gap of different directions from transplanting a cutting, thereby forms steam-water mixing.

On the such scheme basis, described hot water inlet and outlet are equipped with loose joint, are convenient to pipeline and connect.

On the such scheme basis, described cutting is fixed, and the gap between transplanting a cutting equates, as long as the gap between cutting makes steam pass through.

On the such scheme basis, described spacer does not rotate, and described cutting is not rotated, and steam can enter the shell center from transplanting a cutting outside all angles.

The utility model superiority is: (1) adopts loose joint, is easy for installation and removal; (2) application is wide; (3) the steam-water mixing effect is good; (4) parts are few, and are much cleaner.

Fig. 2 is the utility model cross-sectional schematic;

Fig. 3 is spacer and cutting location diagram;

Attached number in the figure explanation:

1---hot water inlet; 2---steam inlet;

3---outlet; 4---loose joint;

51---shell; 52---transplant a cutting;

53---end socket; 54---spacer;

541,542,543---the left, center, right spacer.

The specific embodiment

Below in conjunction with description of drawings, the utility model is further illustrated.

Be that the utility model formalness and Fig. 2 are as shown in the utility model cross-sectional schematic as Fig. 1, a kind of steam heater is loaded on the hot water line, can connect sterilization machine, comprise the hot water inlet 1 that is positioned at shell 51 1 ends, the side is steam inlet 2, the other end is outlet 3, wherein:

In described shell 51, left and right two ends and medium position are provided with the ring-like spacer 541 in left, center, right, 542,543, as shown in Fig. 3 spacer and cutting location diagram, be inserted with between described spacer 54 and transplant a cutting 52, described cutting 52 is radial annular spread and forms the inclination angle along spacer 54.

Shown in Figure 2, export 3 places and be provided with end socket 53, be provided with spacer 54 in described shell 51, two ends are provided with ring-like spacer 541,543, and medium position is provided with ring-like spacer 542, is inserted with between described spacer 54 to transplant a cutting 52.

After hot water enters steam heater from hot water inlet 1, pass through from shell 51 centers, if as shown in Figure 3, namely pass through from spacer 54 centers; And steam enters steam heater from the steam inlet 2 of side direction, after running into described cutting 52, enters shell 51 centers between the gap of 52 different directions from transplanting a cutting, thereby forms steam-water mixing.

On the such scheme basis, described hot water inlet 1 is provided with loose joint 4, for convenience of connecting pipe and dismounting, also is provided with the loose joint (not shown) in outlet 3.

On the such scheme basis, described cutting 52 gaps are fixed, and make steam pass through as long as transplant a cutting the gap of 52.

On the such scheme basis, described spacer 54 does not rotate, and described cutting 52 is not rotated, and steam can enter the shell center from transplanting a cutting outside all angles.
