Embodiment
As shown in Figure 1, the online automatic backwashing filter of the utility model hydraulic pressure of the colliery equipment forms a plank frame on the whole; For the ease of installation and maintenance, reduction difficulty of processing, complete machine comprises four parts, and utilizes screw that each several part is connected and fixed.As shown in Figure 1, on-line automatic backwash filter comprises valve component 2, electromagnetic priority valve 3, connects the transition plate 1 and the connecting plate 4 that is connected with the exterior mechanical interface of valve component 2 and electromagnetic priority valve 3 and transmitting control liquid, electromagnetic priority valve 3 is arranged in valve component 2 sides, selected electromagnetic priority valve 3 can be consistent with the electromagnetic priority valve of combining on the electric liquid main control valve of adopting in the electrohydraulic control system, reduces the kind of electromagnetic priority valve.Simultaneously also installing space be can reduce, dismounting and maintenance are convenient to.The working solution mouth of electromagnetic priority valve 3 communicates with liquid road on the transition plate 1, and then enters main valve plug and realize the backwash action.
Shown in Fig. 2 (a)-Fig. 2 (b), valve component 2 is disassembled to be joint 21, air filtering core assembly 22, valve body 23, element kit 24 and main valve plug 25, and the structure of each several part and position relation are as follows:
As shown in Figure 3, the filter main valve plug mainly comprises: nut 31, snap ring 32, push rod 33, upper valve sleeve 34, spool 35, sealing seat 36, lower valve sleeve 37, spring 38, and the structure of each several part and position relation are as follows:
By the main valve plug structure of on-line automatic backwash filter as can be seen, the main valve plug 25 of valve component adopts the plug-in mounting spool design, nut 31 is main valve plug and valve body 23 connecting element, simultaneously joint 21 is by realizing the communication of main valve plug 25 control liquid and electromagnetic priority valve 3 control liquid, the epicoele of arrival main valve plug 25 with being sealed and matched of nut 31; Push rod 33 slides in upper valve sleeve 34 under the effect of control liquid; Spool 35 drives lower slider at push rod 33, realizes the keying between spool 35 and the sealing seat 36; Spring 38 is installed between lower valve sleeve 37 and the spool 35, realizes resetting of spool 35; Fixing between upper valve sleeve 34 and the lower valve sleeve 37 by being threaded, be connected by snap ring 32 between nut 31 and upper valve sleeve 34, the lower valve sleeve 37.Provided a kind of state position of main valve plug 25 in the drawings, on-line automatic backwash filter is in normal filtration feed flow state.This moment, spool 35 contacted with sealing seat 36, and high pressure liquid directly enters element kit 24 backs for toward the working solution mouth by spool 35, does not communicate with the backwash mouth.When the control liquid confession liquid that is connected with joint 21 on the nut 31, push rod 33 promotes spools 35 and breaks away from sealing seat 36, push rod 33 under the control action of hydraulic force with sealing seat 36 contact seals.This moment, the working solution mouth communicated with the backwash mouth, and the high pressure liquid entering hole is closed, and finishes the backwash working state.
As shown in Figure 4, high pressure liquid entering hole P, backwash mouth X and the working solution mouth A on this on-line automatic backwash filter valve component all adopts cloudy end connector structural design.Its working principle is: the high pressure liquid entering hole P on the complete machine valve component is the high pressure liquid entering hole of complete machine, under the normal filtration working state, high pressure liquid enters element kit through the working solution mouth that the main valve plug liquid entering hole on the valve component flows through on the main valve plug, and then is supplied toward electric liquid main control valve group by the working solution mouth A on the valve component.
When carrying out backwash when work, the liquid entering hole of electromagnetic priority valve 3 communicates with working solution mouth A on the valve component 2 via transition plate 1, and the liquid return hole of electromagnetic priority valve 3 communicates with backwash mouth X on the valve component 2 through transition plate 1.Emulsified liquid after filtering enters in the electromagnetic priority valve 3, is communicated with main valve plug 25 joints on the valve component 2 by the liquid road on the transition plate 1, and control liquid enters main valve plug 25 upper ends.And then promote push rod 33 and in valve pocket, slide, and drive spool 35 and break away from push rod 33 and sealing seat 36 contact seals with sealing seat 36.At this moment, the working solution mouth on the main valve plug 25 communicates with backwash mouth X on the main valve plug 25.And then communicate with backwash mouth on the valve component 2.And one of them filter core still is in proper functioning and filters state on this moment valve component 2, another is then because push rod 33 on the main valve plug 25 and sealing seat 36 sealings, high pressure liquid entering hole P on main valve plug 25 liquid entering holes and the valve component 2 is cut off, be not in the filtration state.According to hydrokinetics, at this moment, the emulsified liquid part after the element kit 24 that is in the normal filtration state filters can flow to the cut element kit 24 of liquid entering hole, realizes the backwash work of this element kit 24.
In the utility model, push-in element kit can also be changed to the element kit of inipple;
In addition, shown in Fig. 5-6, the utility model is by following variation or substitute and can produce the structural type that makes new advances.
As shown in Figure 5, on-line automatic backwash filter comprises element kit 51, valve component 52, electromagnetic priority valve 53 and transition plate 54, on function, can realize function of the present utility model, be the thickness that cost has further reduced backwash filter to increase length on the structure, inner flow passage auxiliary hole processing simultaneously is longer.The function of each component is identical with the function of the above-mentioned Fig. 1 component of the utility model.
As shown in Figure 6, on-line automatic backwash filter comprises valve component 61, electromagnetic priority valve 62, filter core valve body 63 and element kit 64, and the online backflushing of this state is washed filter valve body assembly 61 and processed separately with filter core valve body 64, has reduced difficulty of processing.Simultaneously, the effect of transition plate is changed on valve component 61.Can realize function of the present utility model on the function.
