Embodiment
The total design of the present invention is: mortar jar 2 is divided into two cavitys, between be provided with valve for pressure difference.When a sky
When the mortar liquid level in chamber is too low, valve for pressure difference is opened and is put into the mortar of another cavity, to prevent taking out of mortar pump
Empty.Three kinds of embodiments are introduced below around this design.
The first embodiment: as it is shown in figure 1, this differential anti-evacuation mortar pump, its main body is a mortar
Tank 2, the top of mortar jar 2 is relative with the outlet of ore pulp pipe 1, and the lower section of mortar jar 2 is provided with mortar pump 6,
The entrance 7 of mortar pump 6, in the interior bottom of mortar jar 2, is characterized in: set dividing plate 3 in described mortar jar 2,
Space in tank is divided into main chamber 4 and 5 two, attached chamber part, the top gap 10 of dividing plate 3, dividing plate 3 times
Portion is provided with spilled water hole 8, and place relative with spilled water hole 8, side, dividing plate 3 main chamber 4 is equipped with valve for pressure difference 9.In conjunction with Fig. 2
Fig. 3 is visible: valve for pressure difference 9 has the sliding sleeve 11 of tubulose, sliding sleeve 11 outer end to be provided with end cap 12, and end cap 12 is best
Have through hole 13, in order to ore pulp enters sliding sleeve 11.Sliding sleeve 11 lower wall has discharge opening 14, sliding sleeve 11
The inside be provided with piston plate 15, the plate face around the medial surface of piston plate 15 and spilled water hole 8 is close fit face.
Visible in conjunction with Fig. 4: during work, ore pulp sends into the main chamber 4 of mortar jar 2 from ore pulp pipe 1, by following
Mortar pump 6 is extracted out, is sent to subsequent processing by pipeline.When the mineral syrup liquid in main chamber 4 exceedes gap 10 i.e.
Attached chamber 5 can be injected.Owing to the piston plate 15 inside now valve for pressure difference 9 has attached on dividing plate 3, enclose
Spilled water hole 8, the ore pulp inside main chamber 4 and attached chamber 5 can not pass through spilled water hole 8.Visible in conjunction with Fig. 5: to work as ore deposit
The quantity of slurry reduces or interrupts, and when the liquid level in main chamber 4 drops to gap less than 10, the liquid level in attached chamber 5 is higher than
During main chamber liquid level certain distance, act on the pressure pressure more than side, main chamber of side, piston plate 15 attached chamber,
Piston plate 15 is i.e. open, and the ore pulp in attached chamber 5 will pour main chamber 4, extend that main chamber ore pulp evacuates time
Between.Owing to the time reducing or interrupting of ore pulp supply is the most limited, suitably supplements and can cross the short of ore pulp
Lacking the period, the ore pulp quantity in mortar jar 2 can return to the state shown in Fig. 4, the most repeatedly, Ji Kefang
The only evacuation fault of mortar pump 6, it is ensured that the continuous firing of mortar pump 6.
The second embodiment: the differential anti-evacuation mortar pump shown in Fig. 6 Fig. 7, basic with the first embodiment
Identical, except that: it is provided with spring 17 between valve for pressure difference 9 end cap 12 and piston plate 15.Additionally, end
Preferably with threaded engagement between lid 12 and sliding sleeve 11, can more easily adjust the pressure of spring 17.Every
The gap 10 on plate 3 top is provided with and can intercept the screen pack 16 that gravel passes through, and is possible to prevent sand grains to enter attached
Chamber 5, does not i.e. have the precipitation of sand grains in attached chamber 5, to ensure the mobility of material in chamber, be also beneficial to protect
Hold the airtight performance of piston plate 15.
During work, the counteracted by pressure of spring 17 hydraulic pressure in the attached chamber of part, enhance piston plate 15 to spilled water hole
The closed performance of 8, increases the liquid level distance causing piston plate 15 to be opened, and the ore pulp in whole main chamber 4 is fast
When taking out most, attached chamber 5 just can be opened supplementary, is possible to prevent the frequent movement of piston plate, both can having made of elongate member
With the life-span, the effect of big portion volume in tank can be given full play to again, in the case of the time of ore pulp shortage is longer also
It is possible to prevent to evacuate fault, the performance of the equipment that significantly improves anti-evacuation fault.
The third embodiment: the differential anti-evacuation mortar pump shown in Fig. 8, essentially identical with the second embodiment,
Except that: coordinate for magnetic enclosed between the dividing plate 3 of piston plate 15 and spilled water hole 8 periphery.Namely
Saying have magnetic force to attract between piston plate 15 and spilled water hole 8, closed performance is more preferable.Certainly, magnetic force coordinates
Mode is a lot, can be piston plate 15 be lifting magnet, dividing plate 3 is iron plate.It can also be dividing plate 3
Spilled water hole 8 is provided around magnet ring 18, and piston plate 15 is irony dish.The size of magnetic flux can be according to tank body
Height and liquid level difference demand set.
Use the effect that magnetic force coordinates as the spring of precedent, the hydraulic pressure in the attached chamber of part can be offset, strengthen
The piston plate 15 closed performance to spilled water hole 8, increases the liquid level distance causing piston plate 15 to be opened, aobvious
Write the performance of raising equipment anti-evacuation fault.Its advantage has been that instead of spring, and structure is simpler, and work is more
Reliably.
4th kind of embodiment: as it is shown in figure 9, be provided with mortar pump self-con-tained unit 19 in mortar jar 2.Work as ore pulp
Supply discontinuity overlong time, so that the water in attached chamber 5 is used up, the liquid level inside mortar pump 6 drops to critical height
Time below Du, mortar pump self-con-tained unit 19 auto-action, make mortar pump 6 shut down.After ore pulp supply recovers
Mortar pump self-con-tained unit 19 auto-action, mortar pump 6 Auto Power On.Obviously, this self-con-tained unit has multiple,
Figure enumerates a kind of simplest mode: be provided with the float 20 of mortar liquid surface lifting in tank in mortar jar 2,
Equipped with the push rod 21 of linkage above float 20, push rod 21 matches with the power switch 22 of mortar pump 6.When
When liquid level is less than critical point, the descending disconnecting power switch of push rod 21 22, mortar pump 6 is shut down.When liquid level is crossed
After critical point, the up switch 22 that switches on power of push rod 21, mortar pump 6 starts.Use this structure, can keep away
Exempt from the evacuation accident of mortar pump 6, but due to the unsuitable frequently start-stop of mortar pump, this device reality preferably and above
Execute example to be used in combination, only in the case of ore pulp supply discontinuity and deposit ore pulp are also finished, this dress could be started
Put.Therefore, the critical point set by this device should be less than the opening point of attached chamber 5 spilled water hole 8, such that
Can avoid evacuating fault in the case of unmanned, keep the continuous firing of mortar pump.
