Detailed description of the invention
Referring to figs. 1 through Fig. 3, a kind of raise steam injector of the utility model embodiment is described further.
A kind of raise steam injector, as shown in Figure 1, comprises and drives steam inlet duct 1, receiving chamber 2, driving fluid air inlet pipe 3, mixing chamber 4 and diffuser casing 5, drive steam inlet duct 1 to be provided with nozzle 11.Steam cleaning appliance 6 is provided with in receiving chamber 2, this cleaning device 6 comprises unidirectional cleaning mechanism 61, two-way cleaning mechanism 62 and steam inlet duct 7, wherein, this unidirectional cleaning mechanism 61 comprises unidirectional clean pipe 611, be opened in the first lancing door 612 on unidirectional clean pipe 611, this first lancing door 612 sprays clean steam towards the inwall of receiving chamber 2, this two-way cleaning mechanism 62 comprises two-way clean pipe 621, be opened in two row second lancing doors 622 on two-way clean pipe 621, wherein, each row second lancing door 622 is provided with multiple, two row second lancing doors 622 with the central axis of two-way clean pipe 621 for symmetry axis is symmetrical set, this two row second lancing door 622 is towards unidirectional cleaning mechanism 61 and the outer wall injection driving steam inlet duct 7 simultaneously, this unidirectional clean pipe 611 is all communicated with the chamber 21 that receiving chamber 2 offers with two-way clean pipe 621, to clean in steam injection chamber 21 by steam inlet duct 7, then enter in unidirectional clean pipe 611 and two-way clean pipe 621.
Shown in composition graphs 2 to Fig. 3, and the outer wall of steam inlet duct 7 can be driven to carry out comprehensive cleaning to receiving chamber 2 inwall by the unidirectional cleaning mechanism 61 that arranges in receiving chamber 2 and two-way cleaning mechanism 62, clean steam can be ejected into the inner wall surface of receiving chamber 2 by the first lancing door 612 offered on unidirectional clean pipe 611 by the unidirectional cleaning structure 61 that the position near receiving chamber 2 inwall connects, and makes the solid particle of the attachment of receiving chamber 2 inwall depart under the impact of air-flow thus dispose; Simultaneously, two-way cleaning mechanism 62 is arranged with at driving the outer of steam inlet duct 7, can be cleared up towards a side of two-way cleaning mechanism 62 outer wall and unidirectional cleaning mechanism 61 that drive steam inlet duct 1 by two row second lancing doors 622 arranged for symmetry axis with the central axis of two-way clean pipe 621 simultaneously simultaneously, make the effect of cleaning more thoroughly good.
Further optimization such scheme, in the present embodiment, second lancing door 622 is obliquely installed at an angle on two-way clean pipe 621, the angle of this inclination can be 45 ° or 60 °, in order to reduce the difficulty of processing and ensure the effect of cleaning, the second lancing door 622 is 45 ° and is obliquely installed towards mixing chamber 4.Like this, when the second lancing door 622 can make when carrying out cleaning steam clean steam can continue motion towards mixing chamber 4 direction after running into stop, thus the kinetic energy of clean steam is increased, cleaned impurity can effectively be removed.Meanwhile, the vapor stream of unidirectional cleaning mechanism 61 in cleaning course can be driven at the clean steam moved towards mixing chamber 4, overall cleaning effect is improved further.
The operation principle of raise steam injector is: driving steam by driving steam inlet duct 7, being sprayed by nozzle 11.Because injection effect, driving fluid enters receiving chamber 2 from driving fluid air inlet pipe 3, and follow drive steam enter mixing chamber 4.In mixing chamber 4, a part of kinetic energy of working steam passes to driving fluid, and forms fluid-mixing.In mixing chamber 4, fluid-mixing speed is gradually balanced, and enters diffuser casing 5, raises with pressure simultaneously.The pressure of fluid-mixing when diffuser casing 5 exports will be greater than the pressure of receiving chamber 2 jet body.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
