Abstract
The utility model relates to a magnetic dust remover connected in series between a vacuum apparatus and an oil-sealed type vacuum pump, which comprises a framework shell body (10) which is composed of two connected loop pipe-shaped wind channels. The magnetic dust remover is mainly used for removing industrial magnetic dust so as to protect vacuum pumps. The framework shell body (10) is provided with connecting pipes (7, 8) for connecting a vacuum apparatus with a vacuum pump. Vacuum valve gates (1-6) are distributed in the wind channels. Both sides of the upper loop wind channel are provided with a magnetic field device formed by buckling two magnetic poles. The magnetic poles are composed of the magnet bodies (13) of the water cooling pipe of a magnetic yoke fixing strap. The center strength of the magnetic field is 1000-1500 gausses. The magnetic dust remover which does not reduce the effective pumping speed of an air extracting system has the advantages of simple structure and good dust-removing effect.
Description
The utility model belongs to dedusting technology equipment, particularly a kind ofly be used for preventing that industrial magnetic dust from sucking the magnetic dust-cleaning equipment of the vavuum pump of vacuum equipment, can be widely used in vacuum metallurgy stove, vacuum sintering furnace, vacuum heat, vacuum welding and meet sb. at the airport etc. on the used vacuum equipment.
In vacuum metling, sintering, in the heat treatment process, produce a large amount of metal particles, industrial dust such as slag bits, because of these dust generally can both be adsorbed by magnetic field, so we are referred to as the magnetic dust, it is to vacuum equipment, particularly vavuum pump will cause damage, for preventing corrosion and the wearing and tearing of dust to vavuum pump, generally be between vacuum equipment and oil seal type vavuum pump, to be connected in series vacuum cleaner, as cyclone dust collectors, wet scrubber, rough cleaners etc. are though these dedusters can be removed dust to a certain extent, but can seriously reduce the effective pumping speed of vacuum-pumping system, influence the normal operation of equipment.Advantages such as the employing electrostatic precipitator has the efficiency of dust collection height, and draft loss is little, but because its complex structure costs an arm and a leg, be unfavorable for applying.
The purpose of this utility model provides a kind of simple in structure, can effectively remove industrial magnetic dust, and don't reduces the magnetic dust-cleaning equipment of extract system effective pumping speed.
The purpose of this utility model is achieved by the following technical solution.
The magnetic field with certain magnetic field intensity that utilizes neodymium iron boron magnetic body to set up is adsorbed industrial magnetic dust and is reached dedusting purpose principle.The framework housing of forming by two tubular air channels of continuous ring-type, the top has takes over the gas that is input into metallic dust, fastening the magnetic field device of forming by two magnetic poles respectively on the outer wall of last ring air channel, both sides, the magnetic dust is adsorbed on the inside pipe wall during through magnetic field, the gas of cleaning is taken over by the vavuum pump on the middle air channel and is sucked vavuum pump, is provided with the vacuum valve of several control gas flows and scarfing cinder operation in the air channel.Scarfing cinder work can hocket, and promptly closes respective valves, removes a side magnetic field device, and then the dust on the inwall falls automatically according to the gravity effect, enters scum pipe and discharges, and this moment, the opposite side magnetic field device was still in operate as normal.
Each magnetic pole is all formed by fixing magnet in the semicircle yoke identical with the wind channel tube external diameter, and magnet selects for use NdFeB material to make, and is provided with cooling water pipe in the magnet.
The utility model is compared with prior art equipment has following remarkable advantage: simple in structure, compact, cost is low, no energy consumption, reliable operation, efficiency of dust collection can reach 99%; No matter to the industrial magnetic dust under the room temperature; still the metallurgy industry of high temperature (500 ℃) contains the waste gas of magnetic dust; can both reach desirable dust removing effects; do not reduce the effective pumping speed of vacuum-pumping system; can protect vavuum pump effectively; prolong its service life, thereby whole vacuum equipment production efficiency is improved, reduced operating cost.
Fig. 1, magnetic dust-cleaning equipment structure chart
Among the figure: 1～6 vacuum valve; 7,8, take over; 9, scum pipe; 10, housing; 11, yoke; 12, cooling water pipe; 13, magnet.
Now in conjunction with the accompanying drawings and embodiments the utility model is done an explanation.
As shown in Figure 1, form framework housing 10 by two ring-type tubular air channels that join, there is the adapter 7 that connects vacuum equipment the top; Distribute in the air channel vacuum valve 1～6 is being set; Fastening magnetic field device A and the B that forms by two magnetic poles respectively on the outer wall in last ring air channel, both sides; On the middle air channel adapter 8 that links to each other with vavuum pump is arranged; There is scum pipe 9 the housing below.Each magnetic pole all is to be made of fixed magnets 13 in the semicircle yoke identical with the wind channel tube external diameter 11, and cooling water pipe 12 is arranged in the magnet.Two magnetic pole absorption are buckled on the wind channel tube outer wall and form magnetic field device.Magnet is made by NdFeB material.Central magnetic field intensity is 1000～1500 Gausses.
Operation of the present utility model: start vavuum pump, the gas G that vacuum equipment includes work magnetic dust enters the air channel through taking over 7, vacuum valve 1,4 shuntings through opening enter A, B magnetic field, the magnetic dust is attracted on the tube wall, because valve 3,6 is closed, the valve 2,5 of the clean gas after the dedusting (air-flow) through opening confluxes and takes over 8 suction vavuum pumps in vavuum pump.Because its water conservancy diversion cross section is big, so can not reduce the effective pumping speed of vacuum-pumping system.Again owing to there being good cooling system (12) that magnet is cooled off, so can be in high temperature (500 ℃) or hyperbar, operate as normal under the negative pressure condition.
Scarfing cinder is handled and can be carried out at any time, and as valve-off 1,2,3, Open valve 4,5,6 is removed magnetic field device A, and the magnetic dirt that is then adsorbing on the tube wall falls under the gravity effect automatically, is discharged by scum pipe 9, as a same reason, can remove opposite side slag dirt.Obviously, the scarfing cinder operation can hocket under non-stop-machine situation.
A kind of embodiment now is provided.
This magnetic dust-cleaning equipment is serially connected between φ 120 high temperature sintering furnaces and the 2X-30 type oil seal type vavuum pump, is extracted into the vacuum of 0.12Pa, required time is about 80 minutes.Through using more than a year, pumping fluid still cleans.Pump chamber is not seen wearing and tearing.Under the same condition of work, do not adorn this deduster, pumping fluid two weeks～1 the thick blackout that month promptly becomes sticky, pump chamber has appreciable wear.
