Abstract
The utility model discloses a spiral guide blade, which is provided with a central column. At least three spiral water distributing blades are circumferentially and evenly distributed on the central column; outer spiral angles ranging from 20 degrees to 25 degrees are arranged at the positions of external circles of the water distributing blades; inner spiral angles ranging from 35 degrees to 40 degrees are arranged at the intersected positions of the water distributing blades with the central column; the outer circular surfaces of the water distributing blades are conical; a flow guide conical hole and a jet hole are arranged at the center of the central column; water surfaces of the water distributing blades are arranged on one side at a large end of the flow guide conical hole; and a small end of the flow guide conical hole is connected with the jet hole. The water distributing blades and a conical inner cavity of a spray nozzle can be fixed in an interference fit mode, the arrangement of the jet hole leads water flow to form rotary flow and jet flow for interaction, and atomizing efficiency is further improved so that the spiral guide blade solves the problems that an existing guide blade of an atomizer sprayer is insufficient in water flow momentum exchange when in use, difficult for further improving atomizing efficiency and complicated in spray nozzle processing technique caused by guide blade installation.
Description
Technical field
The utility model relates to the used spirally-guided blade of a kind of cooling tower shower nozzle that atomizes.
Background technology
As everyone knows, the atomizing of water one class I liquid I mainly relies on and rotatablely moves and produce, the basic skills that water generates is rotatablely moved mainly is tangential introduction-type and directing vane chip, use the shower nozzle of tangential introduction-type blade to adopt the lengthening design for the convenient impurity of removing in the water, the rotary speed that will inevitably consume part energy during use and slow down water, influence atomizing effect, and be difficult to remove the foreign material that accumulate, for this reason, people select atomizing effect better, the Guide vane type nozzle of being convenient to dismantle cleaning has substituted tangential introduction-type shower nozzle, but when reality is used, aqueous fluid is just from shape injection in the shape of a spiral between two guide vanes, form the round rotating flow in the eddy flow chamber, and the anhydrous ejection in the center of guide vane, do not become injection stream, aqueous fluid momentum-exchange deficiency, be difficult to further improve nebulization efficiency, guide vane is pressed abd fixed in the nozzle body by trim ring simultaneously, be easy to generate loosening and do not press tightly, moreover installation for the guide vane that satisfies this structure, the lumen orifice of nozzle body has two steps, cause the processing technology of nozzle body comparatively complicated, add and repeatedly to adjust the tool position man-hour, be unfavorable for improving machining accuracy.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of spirally-guided blade is provided, with the guide vane that solves existing atomizer shower nozzle aqueous fluid momentum-exchange deficiency in use, be difficult to further improve nebulization efficiency, and cause comparatively complicated problems of nozzle body processing technology because guide vane is installed.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of spirally-guided blade, has center column, center column circumferentially is evenly equipped with at least three spiral helicine splitter vanes, the cylindrical place of splitter vane has 20 °～25 ° outer spiral angle, splitter vane and center column intersection have 35 °～40 ° inner-spiral angle, the periphery of splitter vane is conical, the center of center column is provided with water conservancy diversion taper hole and spray-hole, big end one side of water conservancy diversion taper hole is the upstream face of splitter vane, and the small end and the spray-hole of water conservancy diversion taper hole join.
Furtherly, described center column circumferentially uniform spiral helicine splitter vane quantity is four, and the outer spiral angle of splitter vane is 24 °, and inner-spiral angle is 39 °.
The conical gradient of the periphery of described splitter vane is 1: 20.
The coning angle of described water conservancy diversion taper hole is 60 °.
Described upstream face is a knife-edge.
The beneficial effects of the utility model are: the utility model is because the periphery of splitter vane is taper shape, can take the mode of interference fit to fix with the conical internal cavity of nozzle body, easy for installation, also simplified the processing technology of nozzle body, the aqueous fluid that is arranged so that of spray-hole sprays back formation rotating flow and injection stream interaction, help the momentum-exchange between hydrone, thereby further improved the nebulization efficiency of aqueous fluid.

The specific embodiment.
In conjunction with the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
As Fig. 1～a kind of spirally-guided blade shown in Figure 3, center column 1 and four spiral helicine splitter vanes 2 with integrative-structure, splitter vane 2 is distributed on the circumferential of center column 1, the periphery of splitter vane 2 is conical, its gradient is 1: 20, can adopt the interference mount with the conical internal cavity of nozzle body, easy for installation simple, also simplified the processing technology of nozzle body, and the inwall of space between adjacent two splitter vanes 2 and nozzle body has constituted four independently flow channel for liquids, the outer spiral angle that has 24 ° at the cylindrical place of splitter vane 2, splitter vane 2 and center column intersection have 39 ° inner-spiral angle, both existence differential seat angle about 15 ° of having an appointment, can impel aqueous fluid in runner, to flow, form four strands of rotating flows, in fact in the flow process of aqueous fluid, not only aqueous fluid self exists viscous friction, also there is friction to exist between aqueous fluid and the flow path wall, speed difference separately, intermolecular momentum-exchange takes place between adjacent stream thigh, exchange heat or mass exchange, make original just active hydrone more active, thereby make the fluid water molecular excitation produce gas and improve evaporation efficiency.
Be provided with water conservancy diversion taper hole 3 and spray-hole 4 at center column 1 center, the coning angle of described water conservancy diversion taper hole 3 is 60 °, the small end of water conservancy diversion taper hole 3 and spray-hole 4 join, water conservancy diversion taper hole 3, do the decompressing speed-increasing motion from the aqueous fluid that water conservancy diversion taper hole 3 big ends enter, the jet that can form one very high speed sprays from spray-hole 4, the injection stream of ejection is expanded in the space and is flowed, and interacts with four strands of rotating flows, has improved the momentum-exchange and the vaporization evaporation efficiency of hydrone.
Big end one side at water conservancy diversion taper hole 3 is the upstream face 5 of splitter vane 2, described upstream face 5 is a knife-edge, can make the inlet resistance of aqueous fluid significantly reduce, can not produce vortex phenomenon, help improving the pace of aqueous fluid and the momentum-exchange between fluid molecule.
Above-mentioned embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed in the protection domain of the present utility model.
