Description
Technical field
The present invention relates to a kind of casting water mist device, relate to specifically a kind of utilize compressed air as power, can grow mold cools down apart from pipeline transmission with twin-stage atomised spray generator.
Background technology
The water smoke producing method mainly contains ultrasonic atomizatio, pressure atomization and compression atomizing, and wherein ultrasonic atomizatio is to utilize ultrasonic vibration to water generates cavitation corrosion phenomenon, and then lets cracked bubble form droplet, makes water fogging; Pressure atomization is to rely on very big pressure differential to make water fogging, and these two kinds of atomizing types all exist water smoke can't grow Distance Transmission, the uneven shortcoming of atomizing particle.Compression atomizing is to utilize compressed air to pass through the tiny mouth of pipe to form high velocity air, and the negative pressure of generation drives liquid and is ejected into together on the obstacle, under high-speed impact, splashes towards periphery to make drop become vaporific particulate to spray from escape pipe; This atomizing type water fog particle is even; But, limited the transmission range after water smoke sprays because after the slim pipe diameter that compressed air the passes through expansion, speed descends; Water smoke only can be dispersed in outlet nearby, can not satisfy water smoke length and transmit apart from pipeline.
In industries such as casting, the mold cools down mode is mainly used air cooling, water-cooled but.Air can will cool off a little through open pipeline and be provided with flexibly, but because the exchange capability of heat of air is poor, cooling capacity is limited, is difficult to reach the requirement of quick cooling.Water-cooled but has higher cooling capacity, but the cooling duct that water-cooled need be sealed causes water-cooled but to be difficult to be applicable to the cooling point layout of complex product mould structure, is difficult to reach the requirement of fixed point cooling.Water smoke is cooled to a kind of emerging mold cools down mode; The cooling duct that has higher cooling effectiveness and need not seal; Can realize mould fixed point, efficient cooling, but the water smoke that atomizer structure in the market produces can not satisfy fixed point, multidigit, long mold cools down instructions for use apart from the pipeline transmission.
Summary of the invention
The problem that the present invention solves provide a kind of utilize compressed air as power, can grow twin-stage atomised spray generator architecture apart from pipeline transmission, the multiple spot of can reallocating cooling usefulness; To satisfy the requirement of complicated die water smoke pipeline transmission back multiple spot cooling, improve cooling effectiveness.
The present invention casts water fog generator, is made up of compressed air hand-hole, compressed air dispensing orifice, undergauge hole A, undergauge hole B, hole enlargement hole A, hole enlargement hole B, blasthole, link block, water smoke outlet opening.
The compressed air hand-hole connects compressed air piping; The compressed air dispensing orifice is distributed to undergauge hole A and undergauge hole B with compressed air; Blasthole connects supply channel; Undergauge hole A and hole enlargement hole A form one-level atomizing structure, and undergauge hole B and hole enlargement hole B form secondary atomizing structure; One-level water smoke transmission hole is the water smoke of secondary atomizing transmission one-level atomizing; The water smoke outlet opening is as the water smoke outlet of secondary atomizing back; Link block is used for sealing; Water fog generator matrix adopting stainless steel.
Hole enlargement hole A and undergauge hole A diameter ratio are more than or equal to 5; Guarantee that one-level atomizing structure can produce the water smoke of fine particle; Hole enlargement hole B and undergauge hole B diameter ratio make that smaller or equal to 2 the compressed-air actuated speed loss of secondary atomizing structure is very little, can very high flowing velocity be provided for the water smoke after the secondary atomizing; Water smoke after the secondary atomizing has high kinetic energy, and secondary atomizing structure also plays the water smoke of one-level atomizing output is assisted atomizing functions once more simultaneously.Secondly the present invention has advantage simple in structure, that processing and fabricating is easy, cost is low.
Benefit of the present invention is, can high speed, refinement, pipeline transmission at a distance, cooling effectiveness is high, cost is low twin-stage atomised spray generator architecture be provided for mold cooling system.

The specific embodiment
This is shown in Figure 1, a kind of casting water fog generator of the present invention, and compressed air hand-hole 6 connects compressed air piping; Compressed air dispensing orifice 5 is distributed to undergauge hole A4, undergauge hole B8 with compressed air; Blasthole 3 connects supply channel; Undergauge hole A4 and hole enlargement hole A2 form one-level atomizing structure, and undergauge hole B8 and hole enlargement hole B10 form secondary atomizing structure; One-level water smoke transmission hole 1 is the water smoke of secondary atomizing transmission one-level atomizing; Water smoke outlet opening 11 is as the water smoke outlet of secondary atomizing back; Link block A7, link block B9, link block C 12 are used for sealing; 13 matrix supporting roles of stainless steel base.
Hole enlargement hole A2 and undergauge hole A4 diameter ratio guarantee that more than or equal to 5 one-level atomizing structure can produce the water smoke of fine particle.The compressed air volume is expanded rapidly, and speed sharply descends and forms big negative pressure, and water is sucked from blasthole 3, and water is atomized into tiny particle.
Hole enlargement hole B10 and undergauge hole B8 diameter ratio make that smaller or equal to 2 the compressed-air actuated speed loss of secondary atomizing structure is very little, form less negative pressure simultaneously; The water smoke of one-level atomizing is sucked; Atomizing is quickened once more, can very high flowing velocity be provided for the water smoke after the secondary atomizing, has higher kinetic energy; Through twice atomizing and have high-speed spray stream, insert the mold cools down pipeline to water smoke outlet opening 11.
