Description
Technical field
The present invention relates to be used for catch the catcher of the resin that falls into the water of pure water manufacture process, more specifically refer to a kind of auto-clearing type resin catching device.
Background technology
In the technical process of preparation pure water, to use ion exchange resin.These resin price costlinesses, equipment amount (just need several tons in the ion exchange tower) greatly, change once and will hundreds of thousands unit arrive millions of units, and therefore will try one's best rationally prolongs its service time to reduce cost.But As time goes on, resin can be constantly aging, and under the effect of water impact, resin can constantly be broken into littler particle, adds resin smaller in the original resin, causes the particle of minor diameter more and more, more and more littler.These tiny resin particles can be escaped from the inlet pipe, drain pipe of the upper, middle and lower of ion exchange tower; resin catcher is exactly to play to be specifically designed to catch these tiny resin particles; in order to avoid they enter into next technological process; influence the pure water quality; avoiding causing adverse effect to the user who uses pure water, is the important barrier in the pure water technology.
The Chinese invention patent specification of Granted publication CN 2289783Y and Granted publication CN 2172155Y discloses negative pressure backpulsing resin catcher and high efficiency resin catcher respectively, though these two kinds of resin catchers respectively have characteristics, effect with certain seizure resin, but all can't realize the resin of jumping a queue is removed; Though Granted publication CN 2289783Y negative pressure backpulsing resin catcher adopts the mode of negative pressure recoil to clear up resin catcher, can't reach desirable effect.
Fig. 1 is a kind of resin catcher of the prior art, mainly is made up of housing 1, seizure filter screen 7, cover plate 106.The similar three-way pipe of housing 1 shape has inlet tube 101, outlet 102, path 10 7, opening 109 is installed.Inlet tube 101 is communicated with installation path 10 7 straight lines, outlet 102 and installation path 10 7 vertical connections, the opening 109 of the relative inlet tube 101 of passage is installed in cover plate 106 shutoff, thereby forms successively through inlet tube 101, the flowing water passage of path 10 7, outlet 102 is installed.Catching filter screen 7 is core structure, is installed on to install in the path 10 7.Flowing into the flowing water of installing in the path 10 7 need could flow out from outlet 102 through this filtration (capture resin that is about in the flowing water falls) of catching filter screen 7.
The gap of catching between the filter element 708 of filter screen 7 is generally 0.25 millimeter, and resin has and has certain elasticity, can be out of shape.Under the impact of high-velocity flow, tiny resin is just jumped the queue in the gap between the filter element 708, will influence system discharge when the resins in the middle of filter element 708 of jumping the queue are more and more, just must clear up removal to the resin of jumping the queue when acquiring a certain degree.Because catcher is made up of very many filter elements 708, this just makes when removing catcher very difficult.The resin of removing in the catcher filter core has two kinds of methods, the one, artificial rejecting usually; The 2nd, fire is roasting.Filter element 708 finedraws have more than 110 meter long after launching, the artificial very difficulty that seems of rejecting.Though fire is roasting quicker, also needs the long time, can produce a large amount of toxic and harmfuls simultaneously, and can pollute filter core.
In addition; clearing up filter element 708 must whole system stop transport completely; from system, split out the filter core of resin catcher; after getting rid of tiny resin again; also filter core to be restored and install back original system. this need shut down and whole pure water of emptying ion exchange towers; the time of whole emptying ion exchange tower needs 2; 3 hours; take the process of catcher apart and want 1 at least; 2 hours; also to install again; the time of the cost of cleaning filter element also will be grown doubly a lot; often removing a catcher just needs one day to several days time. and this had both wasted pure water; load has been missed the production time again. in large-scale pure water processing project; have a plurality of treatment systems; each treatment system has a plurality of resin catchers again, and each resin catcher all need carry out the cleaning of filter core, and each cleaning all will spend long time; it is over a year, extremely unfavorable to producing obviously.
Again as shown in Figure 1, catch filter screen 7 by being located at PVC flange 108 positioning supports that path 10 7 two ends are installed, PVC flange 108 passes through pad 211 sealings with installation path 10 7.Size L is a shell sizes among the figure, size L ' catches filter screen length, because the flexible variable shell sizes L that causes of PVC flange 108 and pad 211 is either large or small, and filter screen length dimension L ' is constant, so in practical work process, site examining and repairing is difficult to make size L and L ' just right.As size L just in time the time, then size L ' be not greatly is exactly little, if size L ' little could leak resin, if size L ' big will squeeze bad catching filter screen.After filter core damages, both increased the cost of maintenance, and also be unfavorable for producing.

The main effect of inside components 3 is to catch filter screen 7 for safe and reliable installation, avoid the incompatibility of shell dimension and seizure filter screen 7 length dimensions, main means are to guarantee that earlier the filter screen size guarantees shell dimension again, separately carry out, and can not leak resin and squeeze bad phenomenon of catching filter screen 7.Be fixed with carrier base 301 in the inside of back-up ring 105, carrier base 301 is parts that are similar to flange-like.Be fixed with many guide-localization bars 302 on carrier base 301, the right side of guide-localization bar 302 is fixed with pivot flange 304.Pivot flange 304 is fixed on the inwall that path 10 7 is installed by a plurality of feets 303.Carrier base 301, guide-localization bar 302, feet 303, pivot flange 304 are fixed as one, and also can be connected as a single entity with housing 1.Have inner cover plate 305 in the outside of pivot flange 304, inner cover plate 305 has the hole.The end that guide-localization bar 302 is positioned at pivot flange 304 is processed into screw thread.When catching filter screen 7 and opening axis 4 after inside components 3 installs, inner cover plate 305 is installed on the guide-localization bar 302 by nut, fix and seal catching filter screen 7, opening axis 4 passes from the hole of inner cover plate 305, and the hole of sealing ring 205 and 208 pairs of inner cover plate 305 of gland and the gap between the opening axis 4 seal.
Catch filter screen 7 and be installed in the cage that the guide-localization bar 302 of inside components 3 forms, effect is that convection cell filters, and that is to say the seizure effect of finishing herein resin, can not catch out them but catch filter screen 7, and just intercept.Catch filter screen 7 and comprise filter element 708 and filter element support 700, filter element 708 is fixed on the filter element support 700, and filter element 708 has identical a lot of, and distributes with certain uniform gap.Filter element support 700 is made of left and right end ring 701,704 and a plurality of cross bars 707 of being welded between the left and right end ring 701,704, the fixing filter element 708 that evenly is intervally arranged in a plurality of cross bar 707 formed cages.All filter elements 708 that are fixed on the cross bar 707 constitute the seizure filter core, fluid flows through from the gap of filter element 708, with the filtration that realizes convection cell and to the seizure effect of resin, the resin particle that this resin catcher captures just is clipped in the centre of two adjacent filter elements 708.In left end ring 701, be fixed with left bearing ring 703, pass through fixedly right bearing ring 706 of right support 705 in the right-hand member ring 704 by left socle 702.Left bearing ring 703 is used to install opening axis 4 with right bearing ring 706.Between left end ring 701 and carrier base 301, seal by pad 201; Between right-hand member ring 704 and inner cover plate 305, seal by pad 202.In order to prevent to catch the filter screen rotation taking place in the filter screen 7, can install a pin 709 additional in right-hand member ring 704 and inner cover plate 305.The inner space of catching filter screen 7 forms filter ante-chamber C.
Opening axis 4 mainly contains three effects, and the one, fixedly catch out parts 8; The 2nd, derive by catching out the resin that parts 8 reject out; The 3rd, transmit to rotate, make and catch out parts 8 and can rotate around opening axis 4.Wherein, the left half of opening axis 4 is installed on left bearing ring 703 and the right bearing ring 706 and with them and forms sliding bearing.The right half of opening axis 4 has axis hole 406 and passes in the middle perforate of inner cover plate 305 and cover plate 106, and axis hole 406 has formed export cavity E.Between opening axis 4 and inner cover plate 305, seal by sealing ring 205 and gland 208.Between opening axis 4 and cover plate 106, seal by sealing ring 206 and gland 209.Be processed with the axle collar 402,403 on the opening axis 4, play, can adopt additive method here, such as using jump ring, nut, the shaft shoulder etc. the location of opening axis 4 with respect to seizure filter screen 7.
The main effect of catching out parts 8 is to catch out the resin of jumping the queue between the filter element 708 of catching filter screen 7, that is to say and catches out the resin that the seizure filter screen is intercepted, and the resin that these are caught out is discharged in the axis hole 406 of opening axis 4.As shown in Figure 7 and Figure 8, catching out parts 8 mainly is made of gear shaping 805 and derivation tube 803.Derive tube 803 and press close to catch the inwall of filter screen 7, have an axial slit on it, on the inwall of deriving tube 803, be fixed with central strip 806.Gear shaping 805 has identical a lot of, and an end is fixed on the central strip 806, and an end stretches out from slit, inserts between two adjacent filter elements 708, and can rotate around opening axis 4 in the gap of filter element 708.Gear shaping 805 also can directly be fixed on the edge of slit.Gear shaping 805 has certain length and thinner, but also has certain elasticity.Like this when gear shaping 805 with deriving tube 803 when opening axis 4 rotates, can adapt to the installation machining deviation (that is to say and be difficult to guarantee that the gap of all filter elements all is to be on the vertical plane of the very high opening axis of same precision 4) of filter element 708.Derive tube 803 left ends and be fixed on by left connecting plate 801 on the axle collar 402 of opening axis 4, derive tube 803 right-hand members and be fixed on by right connecting plate 802 on the axle collar 403 of opening axis 4, derive tube 803 and can do gyration around the central shaft of opening axis 4.Derive between tube 803 and the opening axis 4 and be communicated with by tube connector 804.Derive tube 803 middle cavitys and form collecting chamber D.
The right-hand member of opening axis 4, the external derivation parts 5 of promptly terminal connection.External derivation parts 5 mainly are to control discharging this process of resin, are made of external support 501, outer joint chair 502, external lid 503.Outer joint chair 502 one connect external support 501, and external support 501 is fixed on the housing 1 or on the cover plate 106 or other position.External lid 503 has import and outlet.The end of opening axis 4 inserts in the import of external lid, and by gland 210 and sealing ring 207 sealings.One end of outer joint chair 502 connects the outlet of external lid 503 and by pad 204 sealings, the other end connects valve 504, and valve 504 connects delivery pipe 505 again.Valve 505 is electronic or operated pneumatic valve.External lid 503 forms external control chamber F with outer joint chair 502.
The right section part somewhere that opening axis 4 stretches out housing 1 has keyway 404, and key 601 is installed, and a worm gear 602 (or other can transmission gear) is installed simultaneously, and is fastening by nut 405.Worm gear 602 can drive with motor 604 and speed change gear 603.The base 605 of motor 604 can be fixed on the housing 1 or on the cover plate 106.Above-mentioned worm gear 602, speed change gear 603, motor 604 have constituted the drive disk assembly 6 of this resin catching device.Can drive opening axis 4 when motor 604 rotates rotates.Opening axis 4 can drive derivation tube 803 and rotate together when rotating.
Again as shown in Figure 2, because seizure filter screen 7 has been installed, and the two ends of seizure filter screen 7 encapsulate by pad 201,202 and inner cover plate 305.After the water that has resin is like this come in from intake antrum A, want to arrive in the water chamber B, must be earlier ante-chamber C after filtration, also must be through the gap between the filter element 708.Current are exactly the process that resin is caught through the process in the gap between the filter element 708.The resin that is caught in will be jumped the queue in the gap of filter element 708.Shown in white arrow among the figure.
Again as shown in Figure 5 and Figure 6 because gear shaping 805 has been inserted in the gap between the filter element 708, when gear shaping 805 with deriving tube 803 when opening axis 4 rotates.Gear shaping 805 will streak in the gap between the filter element 708, picks out the resin in the gap of filter element 708 of jumping the queue.This move just can be finished in the several seconds.
As Fig. 2 and in conjunction with Fig. 7 and Fig. 8, in the time will discharging resin, open valve 504 earlier, at this moment collecting chamber D is by export cavity E, external control chamber F is in communication with the outside, collecting chamber D internal pressure is very low, and (the pressure size is roughly identical with the external world, about 0.1MPa), and water chamber B and the interior pressure also very high (approximately 0.5MPa) of filter ante-chamber C, the existence of this pressure reduction makes sub-fraction current in the main current from the slit of the deriving tube 803 into derivation tube 803 that recoils, these sub-fraction current have been carried resin secretly, export cavity E flows through, external control chamber F, valve 504 is discharged to the outside then, shown in black arrow among the figure.Thereby the cleaning that realizes resin is rejected and is discharged.
Can when arriving, this pressure difference value flow to a certain degree will send the automaton that signal (then jumped the queue seriously or acquire a certain degree by resin in the gap between the filter element 8 of explanation seizure parts 7 at this moment) is given motor 604 and valve 504 with the pressure difference value flow between pressure-detecting device or pressure difference detection device or flow detector measurement inlet tube 101 and the outlet 102.Automaton is opened valve 504 and starter motor 604 according to this signal, so just can realize automatically rejecting and discharging resin.
Owing to do not need to pull down seizure filter screen 7 in the process of rejecting resin and in to the resin discharging process of rejecting, therefore do not need to shut down, only being that utilization production is current just can rush out the resin of rejecting with pressure differential space outerpace.
Embodiment 2
Embodiment 2 has introduced a kind of another kind of auto-clearing type resin catching device relatively simple for structure, as shown in Figure 9, the differently place of it and embodiment 1 is, saved inside components 3, catching filter screen 7 is directly installed in the installation path 10 7, be that right-hand member ring 704 directly is fixed on cover plate 106 inboards by bolt or welding manner, left end ring 701 directly connects pad 201, and pad 201 is replaced on the back-up ring 105.The cross section of this pad 201 can be V-arrangement or Y shape.Different in addition places are, the terminal valve 504 that directly connects of opening axis 4, and valve 504 is hand-operated valves, opening axis 4 is not installed worm gear 602 and is driven by motor 604 and speed change gear 603; Pressure-detecting device also useless or pressure difference detection device or flow detector are measured the pressure difference value flow between inlet tube 101 and the outlet 102.Other structure is identical with embodiment 1, and all are by manual operations for this resin catchers, can reach the condition that does not need to stop production equally and clean out the purpose of catching the resin on the filter screen 7 within following a few minutes fast.
Above-mentioned is that to exemplify is more representational embodiment, but the shortcoming of embodiment 2 is to catch filter screen 7 can form cantilever beams and be subject to vibration, the poor and difficult assurance sealing effectiveness of stability.Though and embodiment 1 structure is complicated, catch the fixing reliable of parts 7, impact and the vibration that can bear current, and good airproof performance.
Needing explanation, opening axis 4 is directly to connect valve 504 or to connect valves 504 through external derivation parts 5 be distinguishing, need specifically be provided with according to actual conditions.
When adopting hand rotation opening axis 4 and valve 504 to adopt manually-operated gate, can be directly installed on valve 504 on the opening axis 4, in this case, valve 504 can rotate with opening axis 4, but this point not too can influence the rotation of discharging and opening axis 4.
When adopting when full-automatic in two kinds of situation, after turning over a circle to have cleared up resin, opening axis 4 forwards during auto-reverse again time origin-location, electronic or operated pneumatic valve can be directly installed on the opening axis 4.In this case, valve 504 rotational angles are little, even certain rotation has taken place, also can not have influence on control.But want the continuous equidirectional rotation then must adopt when opening axis 4 and connect valve 504 through external derivation parts 5, not so the continuous rotation of valve 504 will cause being difficult to allow carrying out continuously automatically, because be electronic or pneumatic tube connector or the line all wanted, the phenomenon of " twisting fried dough twist " can appear in these pipes or line.
By the detailed description of above-mentioned two embodiment, can know that the present invention has following beneficial effect:
1, at first be to play basic seizure effect, can pure water unfinished work and the finished product in the technical process be filtered, and the resin in these fluids is caught, avoid resin to enter into next technological process.
2, can easily remove the resin of jumping the queue apace.Removed when jumping the queue resin in the past, difficulty is very big.And this device can high-speed and high-efficiency jump the queue resin between filter element of removing.The process that whole in the past this resin catcher of dismounting is also removed the resin of jumping the queue needs half a day at least, only just can reach predetermined purpose now with one or two minute, the process of removing resin is shortened more than 98%, increase work efficiency greatly, also greatly reduce labour intensity simultaneously.
3, the cleaning removal process that must not stop production and just can finish the resin of jumping the queue.Removing in the past needs system to stop production to shut down, can influence normally carrying out of production like this when jumping the queue resin, and can jump the queue when the producing removing of resin of this device does not influence the operation of production.Have 7 series with pure water system, each serial production capacity is 230m3/ hour, and the pure water price is 30 yuan/m
3, and needed calculate in 6 hours with original each the wait with the time of handling, use this present invention, surplus the benefit that time produced that each reset procedure is saved just has 40,000 yuan.
4, can increase substantially production capacity.Because it is a process gradually that resin clip is filled in filter element, is not just to block the seizure filter core quickly, neither removes once the phenomenon of jumping the queue and catch filter core.That is to say that normal production capacity is 230m
3/ hour, resin takes place jumps the queue and catches after filter screen stops up, production capacity can descend gradually, production capacity from 230 drop to 200 again to 150 again to 120 ... resin was very inconvenient because cleaning is in the past jumped the queue, so can be in the low cleaning removal work that ability is stopped up resin to catcher in can not be low again of production capacity.This influence production is greatly removed the resin of jumping the queue if utilize this device back just can clear up timely.Thereby improve production capacity greatly, this benefit that produces on the one hand also is very huge.
5, the whole process of removing in the past the resin of jumping the queue all needs manually to carry out, and adopt can realize behind the present invention unattended nobody start to finish the removing of the whole resin of jumping the queue, realize automatic operating.Whole in the past process will expend the labour cost of thousands of units at least, and only needs zero several years of zero point electricity just can finish after adopting this device, has saved cost of labor.
