Mud pit, plunger pump, the second check valve and electromagnetic flowmeter are sequentially communicated.
It is further preferred that the Centrifugal Pump and lift are higher than plunger pump.Still more preferably, the centrifugal pump
280 sides of maximum stream flow/hour, 110 meters of H-Max.Still more preferably, the plunger pump discharge is 30~150 sides/small
When.
Second aspect, the present invention provides a kind of plate and frame filter press, it is characterised in that：Including multiple filter press plates and filter cloth,
Multiple filter press plates are mutually coaxially arranged in parallel, and filter press plate both ends of the surface are provided with sunk type press filtration chamber, and filter cloth is set to adjacent two
Between a filter press plate and be covered in sunk type press filtration chamber surface, offered among filter press plate through feed opening, plate and frame filter press into
Expects pipe is connected to through feed opening.
The third aspect, the present invention provides a kind of charging filter-pressing methods, using the sheet frame pressure described in first aspect present invention
Filter feed system, first starts centrifugal pump, when Centrifugal Pump is reduced to the maximum actual flow of plunger pump, closes centrifugation
Pump, opening plunger pump.
The plate and frame filter press feed system and plate and frame filter press and charging filter-pressing method of the present invention has compared with the existing technology
There is following advantageous effect：
(1) setting in parallel centrifugal pump and plunger pump is fed, profit in charging early period of plate and frame filter press using centrifugal pump
Quick filler is carried out with the big flow of centrifugal pump；The later stage is fed in plate and frame filter press, when the pressure rising of plate and frame filter press, centrifugation
When pump starts to feed with low-flow high-lift, centrifugal pump is stopped using, uses plunger pump charging instead；
(2) by using the combining form of centrifugal pump+plunger pump, consider the big flow advantage for both utilizing centrifugal pump, carry out
Fast Filling slurry, and plunger pump stability of flow can be utilized, the advantages of pressure gradually rises, carries out the press filtration in later stage, passes through this
Kind combines to realize the raising of powder feeding efficiency, simple in structure, can effectively reduce charging energy consumption, shortens feed time.

Specific implementation mode
Below in conjunction with the attached drawing in embodiment of the present invention, the technical solution in embodiment of the present invention is carried out clear
Chu is fully described by, it is clear that described embodiment is only some embodiments of the invention, rather than whole realities
Apply mode.Based on the embodiment in the present invention, those of ordinary skill in the art institute without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, on the one hand, the present invention provides a kind of plate and frame filter press feed systems comprising is sequentially communicated
It is single to be homogenized mud pit 1, centrifugal pump 2, the first check valve 3, electromagnetic flowmeter 4, plate and frame filter press feed pipe 5, plunger pump 6 and second
To valve 7.
Wherein, it is homogenized mud pit 1, the prior art can be used in storage homogenizing mud.
Centrifugal pump 2, big using flow, lift is high, the high-power pump housing, specifically, 2 maximum stream flow of centrifugal pump, 280 side/small
When, 110 meters of H-Max.
First check valve 3 plays the role of reversely ending, and prevents mud from flowing back, the prior art can be used.
Electromagnetic flowmeter 4, measures mud flow rate, and the prior art can be used.
Plate and frame filter press feed pipe 5 carries out feeding to plate and frame filter press, the prior art can be used.
Homogenizing mud pit 1, centrifugal pump 2, the first check valve 3, electromagnetic flowmeter 4 and plate and frame filter press feed pipe 5 connect successively
It is logical.It is homogenized mud to extract out through centrifugal pump 2, import in plate and frame filter press.
Plunger pump 6 comes into operation in pressure-filtering process, specifically, 2 flow of centrifugal pump and lift are higher than plunger pump 6.Specifically
, 6 flow of plunger pump is 30~150 sides/hour.
Second check valve 7 plays the role of reversely ending, prevents mud from flowing back, the prior art can be used.
Electromagnetic flowmeter 4, measures mud flow rate, and the prior art can be used.
Homogenizing mud pit 1, plunger pump 6, the second check valve 7 and electromagnetic flowmeter 4 are sequentially communicated.
As shown in Fig. 2, in conjunction with Fig. 3, plate and frame filter press of the invention, including multiple filter press plates 8 and filter cloth 9, multiple press filtrations
Plate 8 is mutually coaxially arranged in parallel, and 8 both ends of the surface of filter press plate are provided with sunk type press filtration chamber 81, and filter cloth 9 is set to two adjacent pressures
Between filter plate 8 and it is covered in 81 surface of sunk type press filtration chamber, is offered through feed opening 82, plate and frame filter press among filter press plate 8
Feed pipe 5 is connected to through feed opening 82.
The charging filter-pressing method of the present invention is as follows：
First start centrifugal pump 1, mud squeezes into sheet frame pressure by the first check valve 3 by plate and frame filter press feed pipe 5 at this time
Filter, since 1 flow of centrifugal pump is big, according to the performance curve of pump, centrifugal pump 1 opens big flow charging at this time, with into fill out
Expect more and more, filter press sunk type press filtration chamber 81 is gradually full of by slurry, and pressure starts to be gradually increasing, at this time centrifugal pump 1
Flow starts to gradually decrease.In whole process, the energy consumption of centrifugal pump 1 is relatively high always, waits for that 1 flow of centrifugal pump is reduced to plunger pump
When 6 maximum actual flow, centrifugal pump 1, opening plunger pump 6 are closed.Since 6 power of plunger pump is less than centrifugal pump 1, and flow is equal
Even stabilization, this stage, which uses the charging of plunger pump 6 instead, just reduces feed time, reduces energy consumption, improves powder feeding efficiency.
The foregoing is merely the better embodiments of the present invention, are not intended to limit the invention, all the present invention's
Within spirit and principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
