The same pole faces of the permanent magnets are opposite for enhancing the gradient of a magnetic field and a heat exchange effect. The utility model can be used for lubrication systems and fluid drive systems of various mechanism devices for decreasing oil temperature. Oil purification can be achieved.
Description
The utility model relates to the shell-and-tube cooling purifier of controlling the oily gentle dustiness of hydraulic drive and lubricating system in the plant equipment.
The temperature of lubricating system, Hydraulic Power Transmission System fluid and cleanliness factor are two key factors that influence the plant equipment reliability.The temperature of fluid is too high, its viscosity is descended, the bearing capacity of oil film reduces, greasy property descends, the leakage of aggravation Hydraulic Power Transmission System and the wearing and tearing of machinery, and the irony particle that wearing and tearing produce is the major pollutants of fluid, it not only causes the obstruction of hydraulic system valve port and stuck, and be the strongest particle that pollutes wearing and tearing, so the temperature of control transmission and lubricating system fluid and cleanliness factor are the keys that improves the plant equipment reliability.
Traditional hydraulic system often adopts cooler to strengthen cooling, yet the volume of various coolers in the market is all bigger, and heat transfer efficiency is lower, is unsuitable for the use of mechanical system; Adopted shell-side enhanced heat exchange device later on, in heat-transfer pipe outside ribbing, to increase heat exchange area, for further limit fluid is mobile to strengthen the shell-side heat exchange, people adopt straight flow-stopping plate or arc flow-stopping plate, what make the shell-side medium mobilely crosses tube bank, do tortuous motion, the local mixing of fluid strengthened, turbulence level is deepened, and fully contact with tube wall, to realize strengthening heat exchange.Because flowing of shell-side is very complicated, nearly all research all must be based on experiment, and this brings a lot of troubles to research work.
The purpose of this utility model is: a kind of shell-and-tube cooling purifier is provided, add a certain amount of poly-magnetic porous media in the liquid flow channel for oil of shell-and-tube cooling purifier, and in central tube or heat-transfer pipe, arrange suitable magnetic field, to improve heat exchange effect, improve the shell-and-tube cooling purifier of the hydraulic drive and the lubricating system cooling of the ferromagnetic pollutant ability of seizure.
The purpose of this utility model is achieved in that a kind of shell-and-tube cooling purifier, mainly comprise: housing, heat-transfer pipe is housed in the housing, central tube reaches and be provided with flow-stopping plate on the internal perisporium of housing, between central tube and heat-transfer pipe, be filled with poly-magnetic porous medium, in central tube and heat-transfer pipe, be furnished with permanent magnet.
The purpose of this utility model can also realize by following scheme:
Above-mentioned permanent magnet is arranged in parallel within the central tube, and identical pole-face is relative.
Above-mentioned permanent magnet is arranged in parallel within the heat-transfer pipe, and identical pole-face is relative.
The optimal porosity of above-mentioned poly-magnetic porous medium is between 0.8-1.
Above-mentioned flow-stopping plate can be straight flow-stopping plate or spiral flow-stopping plate.
The optimal helical angle of above-mentioned spiral flow-stopping plate is between 30 °～50 °.
Above-mentioned heat-transfer pipe is made with outer low rib copper tube.
The pole-face that permanent magnet is identical is relative, and the magnetic line of force is stretched out, and fully magnetization gathers magnetic porous medium, and it is integrated to realize that cooling and magnetic force purify.
Because the utility model has added a certain amount of poly-magnetic porous medium and arranged suitable magnetic field in central tube or heat-transfer pipe in the liquid flow channel for oil of shell-and-tube cooling purifier, make porous media play following effect: 1. with the heat transferred cooling wall in the fluid, 2. strengthen the disturbance of convection current, strengthen heat convection, 3. improve field gradients, promptly improve the ability of catching ferromagnetic pollutant in the fluid.
Make magnetic field play following effect simultaneously: 1. to catch the ferromagnetism contamination particle in the fluid, 2. improve the heat exchanger effectiveness of cooling purifier, 3. cooling water is magnetized, prevention is at the heat-transfer pipe encrustation, thereby maintenance high heat-transfer performance, 4. cooling purifier is used for mining machinery, and magnetized water can improve the dirt ability of going out.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1: a kind of shell-and-tube cooling purifier, mainly comprise: housing 9, heat-transfer pipe 5 is housed in the housing 9, central tube 13 reaches and be provided with flow-stopping plate 8 on the internal perisporium of housing 9, between central tube 13 and heat-transfer pipe 5, be filled with poly-magnetic porous medium 6, in central tube 13 and heat-transfer pipe 5, be furnished with permanent magnet 7.
Above-mentioned permanent magnet 7 is arranged in parallel within the central tube 13, and identical pole-face is relative.
Above-mentioned permanent magnet 7 is arranged in parallel within the heat-transfer pipe 5, and identical pole-face is relative.The magnetic line of force is stretched out, fully the poly-magnetic porous medium 6 of magnetization.
The optimal porosity of above-mentioned poly-magnetic porous medium 6 is between 0.8-1.Littler porosity can cause the speed of flow resistance to rise.
Above-mentioned flow-stopping plate 8 can be straight flow-stopping plate or spiral flow-stopping plate.
The optimal helical angle of above-mentioned spiral flow-stopping plate is between 30 °～50 °.The porosity of the swing angle of spiral plate and poly-magnetic porous medium 6 is important structure key elements of cooling purifier.
Above-mentioned heat-transfer pipe 5 usefulness low rib copper tube are outward made.Other element all adopts the stainless steel manufacturing, avoids the influence to magnetic field.The slit of permanent magnet 7 in the central tube 13 and tube wall allows cooling water to flow through in addition, makes central tube 13 can make heat-transfer pipe, makes permanent magnet obtain cooling simultaneously.
During assembling, a plurality of heat-transfer pipes 5 are evenly distributed on the circumference of air supported head 11, link to each other with air supported head 11, central tube 13 places in the middle of each heat-transfer pipe 5 and with air supported head 11 and links to each other, after being filled with a certain amount of poly-magnetic porous medium 6 between each pipe, be enclosed in the lump in the housing 9, load onto gland 14, end cap 3 then, bolting on gets final product, and cooling water enters each heat-transfer pipe 5 by the water inlet 2 on the end cap 3, all elements in the cooling housing, flowed out by delivery port 1 then, oil is flowed through from the oil-in 10 on the housing and is gathered magnetic porous medium 6, realizes that cooling and magnetic force purify.Flow out from oil-out 4 then, when needing the dirt in the cleaning housing, take off bleeder plug 12 and get final product.
The utility model adopts above structure, the experiment proved that: the average filtration of cooling purifier compares β
