Embodiment
The total design of the utility model is: mortar jar 2 is divided into two cavitys, between be provided with pressure difference valve.When the mortar liquid level of a cavity is too low, pressure difference valve is opened and puts into the mortar of another cavity, to prevent finding time of mortar pump.Three kinds of embodiments are introduced below around this design.
The first embodiment: as shown in Figure 1, this differential anti-mortar pump of finding time, its main body is a mortar jar 2, the top of mortar jar 2 is relative with the outlet of ore pulp pipe 1, the below of mortar jar 2 is provided with mortar pump 6, entrance 7 bottom in mortar jar 2 of mortar pump 6, be characterized in: in described mortar jar 2, establish dividing plate 3, space in tank is divided into main chamber 4 and 5 two, attached chamber part, the top gap 10 of dividing plate 3, the bottom of dividing plate 3 is provided with spilled water hole 8, and dividing plate 3 side, main chamber 4 and spilled water hole 8 opposite position are equipped with pressure difference valve 9.Fig. 3 is visible for composition graphs 2: pressure difference valve 9 has the sliding sleeve 11 of tubulose, and sliding sleeve 11 outer end is provided with end cap 12, and end cap 12 preferably has through hole 13, so that ore pulp enters sliding sleeve 11.Sliding sleeve 11 lower wall has discharge opening 14, and the inside of sliding sleeve 11 is provided with piston plate 15, and the plate face around the inner side surface of piston plate 15 and spilled water hole 8 is close fit face.
Composition graphs 4 is visible: during work, and ore pulp sends into the main chamber 4 of mortar jar 2 from ore pulp pipe 1, is extracted out, be sent to subsequent processing by pipeline by mortar pump 6 below.Attached chamber 5 can be injected when the mineral syrup liquid in main chamber 4 exceedes gap 10.Because the piston plate 15 inside now pressure difference valve 9 has attached on dividing plate 3, enclose spilled water hole 8, the ore pulp inside main chamber 4 and attached chamber 5 is not by spilled water hole 8.Composition graphs 5 is visible: when the quantity of ore pulp reduces or interrupts, when the liquid level in main chamber 4 drops to gap less than 10, when liquid level in attached chamber 5 is higher than main chamber liquid level certain distance, the pressure acting on side, piston plate 15 attached chamber is greater than the pressure of side, main chamber, namely piston plate 15 is open, ore pulp in attached chamber 5 will pour main chamber 4, extends the time that main chamber ore pulp is found time.Because the minimizing of ore pulp supply or the time of interruption are very limited, suitably supplement the short period that namely can pass over ore pulp, the ore pulp quantity in mortar jar 2 can return to the state shown in Fig. 4, so repeatedly, the fault of finding time of mortar pump 6 can be prevented, ensure the continuous firing of mortar pump 6.
The second embodiment: the differential anti-mortar pump of finding time shown in Fig. 6 Fig. 7, substantially identical with the first embodiment, difference is: be provided with spring 17 between pressure difference valve 9 end cap 12 and piston plate 15.In addition, between end cap 12 and sliding sleeve 11, preferably adopt screw-thread fit, the pressure of spring 17 can be adjusted more easily.The gap 10 on dividing plate 3 top is provided with the filter screen 16 that can intercept gravel and pass through, and can prevent sand grains from entering attached chamber 5, namely there will not be the precipitation of sand grains in attached chamber 5, to ensure the mobility of material in chamber, is also conducive to the airtight performance keeping piston plate 15.
During work, the counteracted by pressure of spring 17 hydraulic pressure in the attached chamber of part, enhance the closed performance of piston plate 15 pairs of spilled water holes 8, increase the liquid level distance causing piston plate 15 to be opened, when ore pulp in whole main chamber 4 is taken out most soon, attached chamber 5 just can be opened supplementary, the frequent movement of piston plate can be prevented, both can working life of elongate member, the effect of large portion volume in tank can be given full play to again, also can prevent fault of finding time when the time of ore pulp shortage is longer, the equipment of significantly improving is prevented finding time the performance of fault.
The third embodiment: the differential anti-mortar pump of finding time shown in Fig. 8, substantially identical with the second embodiment, difference is: for magnetic enclosed coordinates between the dividing plate 3 of piston plate 15 and spilled water hole 8 periphery.That is, have magnetic attraction between piston plate 15 and spilled water hole 8, closed performance is better.Certainly, the mode that magnetic force coordinates is a lot, can be piston plate 15 is lifting magnets, and dividing plate 3 is iron plates.Also can be dividing plate 3 spilled water hole 8 around be provided with magnet ring 18, piston plate 15 is irony dish.The size of magnetic flux can set according to the demand of the height of tank body and liquid level difference.
The effect adopting magnetic force to coordinate is the same with the spring of precedent, can offset the hydraulic pressure in the attached chamber of part, enhance the closed performance of piston plate 15 pairs of spilled water holes 8, increase the liquid level distance causing piston plate 15 to be opened, and the equipment of significantly improving is prevented finding time the performance of fault.Its advantage instead of spring, and structure is more simple, works more reliable.
4th kind of embodiment: as shown in Figure 9, be provided with mortar pump automatic control device 19 in mortar jar 2.When ore pulp supply discontinuity overlong time, so that the water in attached chamber 5 is used up, when the liquid level inside mortar pump 6 drops to below critical altitude, mortar pump automatic control device 19 auto-action, makes mortar pump 6 shut down.Mortar pump automatic control device 19 auto-action after ore pulp supply recovers, mortar pump 6 Auto Power On.Obviously, this automatic control device has multiple, exemplifies the simplest mode of one in figure: be provided with the float 20 with mortar liquid surface lifting in tank in mortar jar 2, and the push rod 21 of interlock is housed above float 20, and push rod 21 matches with the power switch 22 of mortar pump 6.When liquid level is lower than transition point, the descending disconnecting power switch 22 of push rod 21, mortar pump 6 is shut down.After liquid level crosses transition point, the up switch 22 that switches on power of push rod 21, mortar pump 6 starts.Adopt this structure, the accident of finding time of mortar pump 6 can be avoided, but due to the unsuitable frequent start-stop of mortar pump, this device is preferably combined with embodiment above, only lay in ore pulp when being also finished in ore pulp supply discontinuity, could this device be started.Therefore, the transition point set by this device lower than the opening point of attached chamber 5 spilled water hole 8, like this, should can avoid fault of finding time in unattended situation, keeps the continuous firing of mortar pump.
