The disk centrifuge control method of the present embodiment, as shown in Fig. 2 whole system is according to figure operation, wherein heavy line
Represent that the valve member is in running order, a deslagging cycle is a circulation, and above-mentioned sequential is performed repeatedly by PLC controls.The party
Method comprises the following steps：The first step, electric control box 30 control the motor 20 of disk centrifuge to start, and then control charging is pneumatic
Valve 1 automatically opens up with discharging pneumatic operated valve 4, while controls the sealing startup of water solenoid valve 12 sealing water is entered by operation water inlet and divide
Disembark piston base, piston base is full of water, by separator drum bore seal, material is separated by material inlet into dish-style
Feed separation is carried out in the rotary drum inner chamber of machine, the clear liquid after separation is discharged by separation purified liquor outlet, and solid slag is gathered in seperator
On rotatory drum wall.Piston a is provided with the bottom of rotary drum inner chamber, valve element and valve body be installed on the outside of piston a, piston a and valve element it
Between form piston a bottom space, the bottom space connects with the sealing aquaporin being arranged on valve element, seals aquaporin and pass through
Pipeline is connected with valve V1, and the top cavity volume between bottom space connection valve element and valve body, is set between piston a and rotatory drum wall
Have sealed nylon ring b, valve element, valve body side wall on be provided with a passage through valve element and valve body, be provided with valve in passage
Valve element c and nylon valve d are sequentially installed with body e, valve body e from inside to outside, there is cavity volume, the appearance between valve element c and its valve body e
Chamber connects the lower cavity between valve element and valve body, and the lower cavity between valve element and valve body is connected by pipeline with valve V2,
And valve body is provided with spilled water hole, the lower cavity between spilled water hole connection valve element and valve body.When seperator normally separates, such as Fig. 4
It is shown, open valve V1（Valve V1 plays sealing function, that is, seals water solenoid valve 12）, operate the sealed aquaporin of water and enter piston a
Bottom space, piston a bottoms is full of water, due to the effect of centrifugal force, the water of piston a bottoms generates huge to piston a
Hydraulic coupling F2, this hydraulic coupling F2 is more than hydraulic coupling F1 caused by the material of rotary drum inner chamber, therefore piston a is support, top
Sealed nylon ring b has been lived, has ensured that rotary drum inner chamber carries out feed separation in the case of sealing.Meanwhile valve element c is produced by its own
Centrifugal force F ensure that nylon valve d is not leaked.After feeding the opening of pneumatic operated valve 1, separating liquid is constantly separated into rotary drum, Gu
Body particle is separated from separating liquid, and accumulates on rotatory drum wall, and clear liquid is mutually discharged by centripetal discharge pump.
Second step, feed separation for a period of time after, electric control box 30 judge rotary drum inner chamber whether need carry out deslagging, if
Deslagging is needed, then the control of electric appliance control box 30 is opened water solenoid valve 13 and started, and deslagging water is separated by operation water inlet into dish-style
Open seperator piston in machine, solid slag enters slag phase collector 23 on separator drum wall after piston is opened, then through slag phase
Outlet is discharged into slag case 21, and then control sealing water solenoid valve 12 starts seals to separator drum inner chamber, sealing one
The control flushing startup flushing water of water solenoid valve 11 is entered in seperator by flushing water inlet after fixing time rushes to rotary drum inner chamber
Wash, feed separation EP (end of program), if not needing deslagging, continue feed separation.When the deslagging cycle starts, as shown in figure 5,
Open valve V2 and open deslagging（Valve V2 is unlatching water solenoid valve 13）, deslagging water enters valve through the lower cavity between valve element and valve body
Cavity volume between core c and its valve body e, deslagging water is filled with the cavity volume, centrifugal force F3 surpasses caused by deslagging water in the cavity volume
Valve element c itself centrifugal force F is crossed, valve element c is moved inwards, and nylon valve d is turned on, formed with logical between nylon valve d and valve element c
Road, the passage are connected by the top cavity volume between valve element and valve body with piston a bottom spaces, the work of such piston a bottoms
It is discharged with water through nylon valve d, hydraulic coupling F2 is gradually reduced with effect water discharge, and a deslagging water part is arranged by spilled water hole
Go out outside rotary drum, another part is full of the lower cavity between valve element and valve body.In tapping process, as shown in fig. 6, piston a bottoms
Effect water is gradually drained, and hydraulic coupling F2 gradually becomes smaller than hydraulic coupling F1, and piston a is to moving down in the presence of hydraulic coupling F1
Dynamic, rotary drum carries out deslagging, and solid particle is discharged outside rotary drum by the ash pit on rotatory drum wall, is then shut off valve V2, valve element and valve
Deslagging water is gradually discharged by spilled water hole in lower cavity between body, and centrifugal force F3 is gradually reduced, valve element c centrifugal force F by
Gradually it is more than centrifugal force F3, therefore valve element c is displaced outwardly, and enclose nylon valve d.Meanwhile open valve V1, operation water by positioned at
Sealing aquaporin on valve element enters piston a bottom space, and is gradually filled with piston a bottoms, and hydraulic coupling F2 becomes larger, envelope
The separated space on piston a tops is closed.During deslagging end cycle, as shown in fig. 7, hydraulic coupling F2 is produced more than rotary drum inner chamber material
Raw hydraulic coupling F1, piston a are returned to the position of closing, and piston a upper and lower cavities have been filled with liquid, and interface location returns to just
Normal mask work state, whole tapping process terminate.
Whether the liquid level information of slag case 21 that 3rd step, electric control box 30 gather according to liquid level sensor 17 judges slag case 21
Deslagging is needed, if desired deslagging, then control pulp pump 16 to start, slag liquid in slag case 21 is discharged, otherwise, control pulp pump 16, which is in, to close
Closed state.
After 4th step, feed separation EP (end of program), the control of electric control box 30 charging pneumatic operated valve 1 and discharging pneumatic operated valve 4 close
Close, while control CIP feed liquors pneumatic operated valve 2, CIP to go out hydraulic pneumatic valve 5 and cleaning water outs valve and open, in separator drum inner chamber
Band slag flushing water is first discharged by cleaning water outs, and the rotary drum inner chamber that CIP cleaning fluids are entered seperator by the import of CIP cleaning fluids again is entered
Row CIP cleaning procedures, the residual dirt being adhered on rotatory drum wall is removed, the CIP cleaning fluids after cleaning are arranged by CIP rinse liquid outlets
Go out.
5th step, the control of electric control box 30 are opened water solenoid valve 13 and started, and deslagging water is entered by operation water inlet to be separated
Machine opens seperator piston, and the residual dirt after CIP cleanings is discharged into slag case 21 through slag phase outlet, is controlled after waiting certain time
