Described impeller 7 and filtering board 6 alternative arrangement successively, and the quantity of impeller 7 is than the quantity of filtering board 6 many 1; On central shaft 8, every 5 filtering boards 6, washing filter plate 9 is installed.Also can follow according to user's requirement and material filtering, concentrated technique needs, carry out the increase and decrease adjustment of filtering board 6, washing filter plate 9 and impeller 7 quantity.
As Fig. 7 and 8, the washing filter plate 9 arranging in multiple purpose aeroplane can be realized filter cake is washed.Adding a washing filter plate 9 is to wash, and it is two to wash that several, interval filter plate adds a washing filter plate 9 again, just adds several washing filter plates 9 as needs repeatedly wash more.
Filter medium is all installed in described filtering board 6 both sides, and described filter medium is filter cloth; Described filtering board 6 and washing filter plate 9 are equipped with bearing bar in both sides, top separately, and both are all suspended between described front support plate and rear support plate by two bearing bars; The bottom of described filtering board 6 and washing filter plate 9 is equipped with filtrate arm 3, and described filtering board 6 connects described filtrate manifold 17 by filtrate arm 3; Described washing filter plate 9 tops are provided with water filling port.
On described reduction box 11, torque tester 14 is installed, the torque of the central shaft 8 that described control valve 13 detects according to torque tester 14 regulates openings of sizes automatically.
Described multiple purpose aeroplane also comprises hydraulic power unit 20, and described hydraulic power unit 20 is pressed into hydraulic jack 1 by oil inlet pipe by hydraulic oil, and hydraulic jack 1 promotes movable pressing board 5 and compresses every filtering board 6.
Described filtrate manifold 17 is provided with triple valve 19, realizes the backwash of filtrate by switch three-way valve 19, and then realizes filter cloth regeneration; Filter cloth regeneration method can be filtrate backwash, can be also blow-back.
Described filtrate manifold's 17 ends are filtrate (liquid, and described control valve 13 one end connect rear branching holder 10 by pipeline, and the other end connects slurry outlet; The practicable automatic control of control valve 13 and manual adjustments control.
The material that central shaft 8 adopts is 0Cr13Al, it is with the alloy preparation that carbon content is 0.075%, silicone content is 0.94%, manganese content is 0.97%, phosphorus content is 0.035%, sulfur content is 0.025%, chromium content is 14.0%, surplus is iron, and described percentage is percetage by weight.
Operation principle is as follows:
1, adopt the principle of cross-flow filtration.Cross-flow filtration is exactly directly to filter with filter cloth (filter medium).In the time filtering, on filter cloth, do not stop or stop less filter cake.This filter type, continuous charging slurry is chronic, does not need to stop to unload filter cake, and filter efficiency is very high.The isolated by filtration machinery of current domestic use, what major part was used absolutely is cake filtration principle.But filter cake is reaching after certain thickness, slip is just difficult to filter, and must lay down filter cake and carry out next circulating filtration.
2, the machine is in the time filtering operation, and slip is to add from the charging aperture of movable pressing board, and the running trend of slip is as shown in Fig. 9 arrow.The rotary centrifugal force that pressure by charge pump and central shaft impeller are rotated, promotes slip and flows to the each filtering board of postorder, and slip is in the mobile process of operation, and (liquid-solid separation) filtered in the effect that is subject to filtering board inside and outside differential pressure.Slip finally flow to the discharging opening of rear branching holder.What discharging opening flowed out is the slip after filtering and concentrating, and filtrate is flowed out from filter plate below filtrate (liquid.
3, the filter chamber pressure of the machine is from the pressure of charge pump.By regulating the switching mouth size of discharging opening control valve, control the load size of discharging opening, just can obtain the needed whole pressure of filter chamber.Between two filter clothes of filter plate, be empty, direct-connected logical with filter plate below liquid outlet.Filtrate manifold is connected with filtrate receiver, and filtrate receiver blow-by is with no pressure, so the inside and outside pressure reduction that just formed of filter cloth.When filtration, under the pressure-acting of filter chamber, filtrate sees through filter cloth and flows in the filter plate of hollow, flows out through filtrate (liquid, and the liquid in slip is separated by filter cloth.Slip after separation is realized concentrated.
4, the machine is provided with central shaft torque measuring ability.It is low that the solids in pulp of charging has height to have, and torque when central shaft rotates also has height to be had low.Automatically control the control valve of discharging opening by the torque size of inspection center's axle.When torque is large, control valve opening strengthens automatically; Torque hour, control valve turns down automatically.By the automatic control to control valve, can make the solids in pulp after concentrating more stable.(torque detector and control valve regulate automatically)
5, the operating pressure of the machine design is 0.8MPa.In the time that filtering and concentrating starts, need adjustment slowly and increase filter chamber pressure, the discharging that reaches technological requirement contains and working pressure admittedly.It is mainly the automatic regulating valve that regulates discharging opening.As little in filter chamber internal pressure, slurry outlet containing low, is pressed line unit by manual mode admittedly, and pipe clip valve is clamped, and reduces slip discharge rate.When adjustment, also to, in conjunction with charging pump lift and flow, coordinate and regulate by frequency control and control valve.Adjusting reaches after technological requirement, is transformed into automatic control program and normally moves.(control valve manual adjustments)
6, when the machine runs to some cycles, the amount of filtrate of discharge reduces to a certain amount of, and when filter chamber internal pressure rises to certain value, the state of being blocked appears in filter cloth, will carry out filter cloth regeneration.The backwash of filter cloth regeneration available water, also can use compressed air blowback.When filter cloth regeneration, first stop feed pump, manually tune up the automatic regulating valve opening of slurry outlet, switch the triple valve of filtrate (liquid to relevant interface, be connected and carry out filter cloth regeneration with the water recoiling or gas.
7, as user requires filter cake to wash, can increase washing filter plate, according to the needs of filtering and concentrating and washing process, filter plate and washing filter plates be synthesized to filtration, concentrated, washing mode, also repeatedly washing mode of one-tenth capable of being combined.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit, although the utility model is had been described in detail with reference to above-described embodiment, those of ordinary skill in the field are to be understood that: still can modify or be equal to replacement detailed description of the invention of the present utility model, and do not depart from any amendment of the utility model spirit and scope or be equal to replacement, it all should be encompassed in the middle of claim scope of the present utility model.
