Detailed description of the invention
Below in conjunction with Fig. 1 to Fig. 5, vacuum filter of the present invention is described in further detail.
As shown in Figure 1, vacuum filter of the present invention, comprises cavity 11, top board 4, quick-actuating closure 5, even flow plate 2, cooling tube 6, filter core 5, vavuum pump 8.
Cavity 11 is cylindrical shell, bottom surface is cambered outwards arc, side is provided with air inlet 1, bottom surface is provided with gas outlet 7, air inlet 1 is connected with specific gas pipeline by control valve 9, gas outlet 7 is connected with vavuum pump 8 by control valve 9, thus under the effect of vavuum pump 8, specific process gas enters cavity 11 from air inlet 1.
Center in cavity 11 is provided with filter core 5, and filter core 5 is cylindrical shell, and sidewall is provided with filter bores, and in order to increase the area of filtration, improve the efficiency of filtering, the sidewall of filter core 5 is accordion, as shown in Figure 5.
As the bottom mounting plate 13 in Fig. 2 cavity 11, installing plate 13 is circumferentially welded in the lower arcuate surface of cavity 11, installing plate 11 center is fixed with nut 15, and screw thread depression bar 16 is spirally connected axially across filter core 5 and nut 15 from filter core 5 end face, thus is fixed on installing plate 13 by filter core 5.For the ease of picking and placeing of filter core 5, installing plate 13 end face is circumferentially with the guide plate 14 of setting.Filter core 5 bottom surface is ring surface, be tightly connected by sealing gasket 12 between ring surface and installing plate 13, installing plate 12 is opening except the structure of hold-down nut 15, thus make to communicate with gas outlet 7 large area in filter core 5, make the outflow filter more fast of the gas after filtration, filter efficiency is further enhanced.
Cavity 11 inherence is closed on air inlet 1 place and is provided with even flow plate 2, and process gas enters cavity 11 from air inlet 1, through even flow plate 2, around the filter core that gas is evenly distributed in cavity 11 more, and increased efficiency.
Be provided with cooling tube 6 in filter core 5 outside, cooling tube 6 from along filter core 5 circumference from and lower winding, the two ends of cooling tube 6 are led to outside cavity 11 respectively.As shown in Figure 3, at the fixed cover 21 of cooling tube 6 outside weldings tubulose on cavity 11 outer wall, cooling tube 6 leads in fixed cover 21, cooling tube 6 is followed successively by fixed cover 21, the spacer 19 communicated with cooling tube 6 and pipe joint 25, three's internal diameter is identical, spacer 19 is identical with the external diameter of pipe joint 25 and be all greater than the external diameter of cooling tube 6, the internal diameter of fixed cover 21 and the external diameter of this three adapt, cooling tube 6, O RunddichtringO 17 is provided with between spacer 19 and pipe joint 25, because spacer 19 external diameter is greater than cooling tube 6, therefore 0 type circle both sides between spacer 19 and cooling tube 6 are inwall and spacer 19 end face of fixed cover 21, be provided with locking nut 18 outside fixed cover 21, tighten locking nut 18, thus the O RunddichtringO 17 between pipe joint 25, spacer 19 and cooling tube 6 is compressed, play sealing function.O RunddichtringO 17 wherein between fixed cover 21 and spacer 19 plays the effect sealing gas in outside air and cavity, and fixed cover 21 internal diameter is chamfered transition face, can play better sealing effectiveness; O RunddichtringO 17 between spacer 19 and pipe joint 25 plays the effect sealing cooling medium, enters in cooling tube with ensureing cooling medium ne-leakage.Also be provided with pad 20 between locking nut 18 and pipe joint 25, be convenient to adjustable pipe joint 25, spacer 19 and the error in length between cooling tube and fixed cover 21.
As shown in Figure 4, cavity 11 top is provided with cavity flange 23, and top cover 4 is connected with cavity 11 by bolt 24.
Top cover 4 bottom surface is circumferentially provided with a circle groove, is provided with O RunddichtringO 7 in groove, between top cover 4 and cavity flange 23 under the effect of bolt 24, completes sealing by O RunddichtringO 7.When only needing to carry out overhauling on a large scale except filter core 5 in whole cavity 11, just the bolt 24 of top cover 4 all need be screwed down.
For the ease of opening soon top cover 4, conveniently overhaul filter core 5, top cover 4 is annular cover, and top cover 4 top is also provided with quick-actuating closure 3, and quick-actuating closure 3 is connected with top cover 4 by HOOK BOLTS 22.In like manner structure between top cover 4 and cavity flange 23, is provided with O RunddichtringO 7 between quick-actuating closure 3 and top cover 4; And quick-actuating closure 3 end face is circumferentially with the groove matched with the eave tile of HOOK BOLTS 22, thus when eave tile embeds in groove and HOOK BOLTS 22 is tightened, between quick-actuating closure 3 and top cover 4, complete sealing.And when filter core is cleaned or more renew cartridge time, only need loosen HOOK BOLTS 22 eave tile is spun out from the groove at quick-actuating closure 3 top, can open quick-actuating closure 3 to overhaul, tighten HOOK BOLTS 22 again after Awaiting Overhaul, whole process is convenient, fast, efficient.
As shown in Figure 1, quick-actuating closure 3 top is also provided with vent valve 10, when needs are to when overhauling in cavity 11, can open vent valve 10 and abolish process environments in cavity 11, make cavity 11 external and internal pressure identical, thus open top cover 4 or quick-actuating closure 3.
During work, under the draft effect of vavuum pump 8, gas enters cavity 11 by air inlet 1, gas is first through even flow plate 2, pass from the gap between cooling tube 6 after gas uniform dispersion, high-temperature gas cools fast, enters filter core 5 subsequently complete filtration by the sidewall of filter core 5, can remove the gas containing corrosivity or harmfulness (really up to the mark, chance moisture change is glutinous) dust granules in gas;
For the situation that dust in up-stream system is too much, often need frequently to change and cleaning filter core 5, replacement operation of the present invention is simple, quick, first up-stream system and the control valve between vavuum pump 8 and cavity 11 9, and cut-out associates with upstream and downstream system; Then vent valve 10 is opened, vacuum breaker; Without the need to other instruments, hand turns on quick-actuating closure 3 upper hookhead bolt 22, can open quick-actuating closure 3; Hand turns on screw thread depression bar 16, i.e. replaceable cartridge 5.
Vacuum filter of the present invention has the effect of vacuum, water-cooled, Chalk-dust filtering:
1. vacuum.Equipment sealing property, withstand voltage properties all meet high-vacuum apparatus standard, and interface adopts standard to connect soon, easy to connect, efficient, and top cover adopts vacuum flange to compress the sealing of O RunddichtringO, and adopts HOOK BOLTS so that fast assembling-disassembling; Intake-outlet adopts locking nut to screw, and compresses O RunddichtringO, reaches the double effects of vacuum seal and water pipe sealing.
2. water-cooled.Outside filter core, close arrangement cooling water pipe, makes high-temperature gas first lower the temperature before entering filter core; Avoid the destruction to filter core, vavuum pump, upstream and downstream system;
3. dedusting.Air inlet, under the draft effect of vavuum pump, by even flow plate, water cooling tube, sucks and enters filter core, after filtration after net filtration, enter vavuum pump, discharge, thus avoid high temperature, corrosivity and harmfulness dust granules to the destruction of vavuum pump, upstream and downstream system.
As mentioned above, plan content given in conjunction with the accompanying drawings and embodiments, can derive similar technical scheme.In every case be the content not departing from technical solution of the present invention, any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
