Abstract
The utility model discloses a steam injector in the production technology of rice bran oil. The steam injector comprises a nozzle and a mixing pipe which are connected with each other through a screwed joint, wherein a drainage hole is formed in the mixing pipe, corresponding to the outlet of the nozzle; the nozzle comprises a contraction segment in the shape of an inverted taper, and the length of the contraction segment is 2-6 times outlet diameter of the nozzle. The steam injector is high in efficiency.
Description
Technical field
The utility model relates to injector technical field, is specifically related to the steam jet ejector in a kind of rice bran oil production technology.
Background technology
Steam jet ejector, is widely used in weaving, papermaking, oil, thermoelectricity etc. and usings in the industry of steam as power, is mainly used to promote vapor recycle, improves low-pressure steam pressure.Steam jet ejector is mainly comprised of nozzle and mixing tube, and steam, in nozzle enters mixing tube, then enters heat exchanger by mixing tube, for the normal temperature solution in heating heat exchanger cylindrical shell.In rice bran oil production technology, need to rice bran crude oil be heated with steam, with the solvent containing in evaporation rice bran crude oil, thereby improve the purity of rice bran oil, in the production technology of rice bran oil, the structure of nozzle is larger to the performance impact of steam jet ejector, and in prior art, existence is because of the problem of the efficiency of the structure influence steam jet ejector of nozzle.
Utility model content
The purpose of this utility model is to overcome above shortcoming, and the steam jet ejector in a kind of rice bran oil production technology that can raise the efficiency is provided.
The technical solution of the utility model is:
Steam jet ejector in a kind of rice bran oil production technology, comprise nozzle and mixing tube, described nozzle is connected by nipple with described mixing tube, on the described mixing tube corresponding with the exit position of described nozzle, be provided with conduction hole, described nozzle comprises contraction section, described contraction section is back taper, and the 2-6 of the outlet diameter that the length of described contraction section is described nozzle doubly.
Further, the inwall of described nipple is provided with the first screw thread, and described nipple is threaded by described first with described nozzle; The outer wall of described nipple is provided with the second screw thread, and described nipple is threaded by described second with described mixing tube.
Further, described nozzle is ceramic material.
Steam jet ejector in the rice bran oil production technology that the utility model provides, tool has the following advantages:
1, the steam jet ejector in the rice bran oil production technology that the utility model provides, comprise nozzle and mixing tube, described nozzle is connected by nipple with described mixing tube, on described mixing tube corresponding to the exit position of described nozzle, be provided with conduction hole, described nozzle comprises contraction section, described contraction section is back taper, and the 2-6 of the outlet diameter that the length of described contraction section is described nozzle doubly.By the length of appropriate design nozzle and the ratio of jet expansion diameter, make the jet coefficient of nozzle enough large, the driving fluid entering from conduction hole fully mixes fast with steam, thereby has improved the efficiency of steam jet ejector, and the efficiency of heating surface that has improved heat exchanger.
2, the steam jet ejector in the rice bran oil production technology that the utility model provides, the inwall of described nipple is provided with the first screw thread, and described nipple is threaded by described first with described nozzle; The outer wall of described nipple is provided with the second screw thread, and described nipple is threaded by described second with described mixing tube.Nozzle is connected with nipple by screw thread respectively with mixing tube, simple in structure, easy to connect, and when nozzle wear or stop up while need to change, it is convenient to change.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the steam jet ejector in the utility model rice bran oil production technology;
Reference numeral: 1-nozzle, 2-mixing tube, 3-nipple, 4-conduction hole.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
The specific embodiment
In conjunction with Fig. 1, steam jet ejector in a kind of rice bran oil production technology, comprise nozzle 1 and mixing tube 2, nozzle 1 is connected by nipple 3 with mixing tube 2, on the mixing tube 2 corresponding with the exit position of nozzle 1, be provided with conduction hole 4, nozzle comprises contraction section, and contraction section is back taper, and the 2-6 of the outlet diameter that the length of contraction section is nozzle doubly.
Conduction hole is set on mixing tube, and steam sprays from nozzle, and heat exchanger inner barrel divides rice bran crude oil to be entered in mixing tube by injection by conduction hole, and steam enters in cylindrical shell after fully mixing with rice bran crude oil, for heating the normal temperature rice bran crude oil in cylindrical shell.By the length of appropriate design nozzle and the ratio of jet expansion diameter, make the jet coefficient of nozzle enough large, the driving fluid entering from conduction hole fully mixes fast with steam, thereby has improved the efficiency of steam jet ejector, and the efficiency of heating surface of heat exchanger.
Conduction hole can be set to several, is evenly distributed on the mixing tube corresponding with the exit position of nozzle, as bloop, reduces the noise that steam jet ejector produces in running.
In the present embodiment, the inwall of nipple is provided with the first screw thread, and nipple is threaded by first with nozzle; The outer wall of nipple is provided with the second screw thread, and nipple is threaded by second with mixing tube.In accompanying drawing, the first screw thread and the second screw thread do not show.Nozzle is connected with nipple by screw thread respectively with mixing tube, simple in structure, easy to connect, and when nozzle wear or stop up while need to change, it is convenient to change.Except the technical scheme of the present embodiment, nozzle can also be welded to connect with nipple.
In the present embodiment, nozzle 1 is preferably ceramic material, and ceramic material is high temperature resistant, and corrosion-resistant, long service life.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing, be equal to replacement etc., within all should being included in protection domain of the present utility model in protection domain of the present utility model.
