It is connected with one end of 6 shaft of segmental support, the second cylinder 9 is allowed to work when needing, segmental support 6 is made to overturn 90 °；It is hollow if you need to remove
When the sediment being detained in piston rod 5, segmental support 6 is allowed to be in top position, introduces compressed air from the second inlet duct 49, and beat
Begin to rehearse slag ball valve 1, allows outside sediment discharge machine；
Shuttle valve component is stuck in rotary drum using the frictional resistance of lower seal 17 and upper seal 21 and 11 inner hole of rotary drum cylindrical section
The top of component, mandril 42 overcomes the active force of the first spring 15 at this time, withstands 23 lower end surface of liqiud outlet head, makes intermediate spool 43
Male cone (strobilus masculinus) and shuttle valve upper half 20 inner conical surface between form circumferential weld 16, reserve overflow ducts for clarified solution；
Before the operation of shuttle valve discharging tubular type solid-liquid separating machine, if needed can refrigerant inlet 44 from below into annular collet 12
Add refrigerant, used refrigerant overflows from the refrigerant exit 19 of top, takes away 46 internal cause rotor high speed rotation of casing and rub with air
The heat wiped and generated；When needing, vacuum pump can also be connected on vacuum suction mouth 10, allow casing 46 is interior to form low vacuum shape
State reduces the friction of rotary drum and air；
When shuttle valve discharging tubular type solid-liquid separating machine works, drum assembly high speed rotation is mounted on liqiud outlet head 23 and logical with overflow
Effect of the slide valve 41 that road 37 intersects vertically by powerful centrifugal force, and the active force of third spring 40 is overcome to press to third bullet
Spring abutment 39 is prepared to open overflow ducts 37 for clarified solution overflow；Suspension introduces rotary drum through feeding-passage 47, to liquid
When tank depth reaches overflow ducts 37, clarified solution starts overflow, and outside 38 discharge machine of drain pipe, through separation after a period of time
Later, when detecting that clarified solution becomes cloudy, stop feeding and drum assembly is allowed to stop operating, be mounted on liqiud outlet head 23 at this time
Slide valve 41 it is mobile towards the center line of main shaft 35 under the action of third spring 40 and close overflow ducts 37, remain in simultaneously
The liquid on sediment surface collapses in drum assembly, and enters 46 bottom of casing from the lower mouth of rotary drum conical section 7, by being arranged in machine
Outside the 4 discharge machine of raffinate passing away 3 and valve of 46 bottom of shell；The movement of second cylinder 9 pushes segmental support 6 to rotate by the arm of force
90 °, the hollow piston rod 5 being mounted in cylinder block 2 is allowed to rise, makes the sealing ring 25 for being mounted on 5 top of hollow piston rod and turn

Movement drives crossbeam 30 to driving air inlet head 61 to move down, be mounted on inner cone sealing ring 58 below air inlet head first with
The hollow tube outer cone 57 of hollow tube 26 contacts, and presses second spring 27 by 29 inner ring of ball bearing being mounted on hollow tube 26
Contracting, so that shuttle valve component be pushed to move down a small distance, reserves a closing between liqiud outlet head 23 and shuttle valve upper half 20
Space, the mandril 42 being fixed on intermediate spool 43 rise under the action of the first spring 15 with intermediate spool 43, close
Circumferential weld 16, after hollow tube 26 is depressed into extreme position to the air inlet head 61 on crossbeam 30, by inlet channel 60 to hollow tube
26 gas supply, are pushed into downwards rotary drum conical section 7 for shuttle valve component, to sediment is squeezed out out of rotary drum, and successively through hollow piston
Bar 5 and deslagging ball valve 1 will be outside most of sediment discharge machines；
Hollow piston rod 5 retreats to downwards extreme position, then drives the shaft of segmental support 6 to rotate 90 ° to figure using the second cylinder 9
1 shows position, and hollow piston rod 5 moves again up, and the sealing ring 25 in portion mounted thereto and the segmental support of 6 lower section of segmental support are close
It closes cone 48 and constitutes sealing, compressed air is entered the hollow part of hollow piston rod 5 by the second inlet duct 49, will remain in that
In sediment by outside 1 extruder of deslagging ball valve；
Hollow piston rod 5 retreats to downwards extreme position again, allows sealing ring 25 and the closely sealed cone 48 of segmental support to disengage, utilizes the second gas
Cylinder 9 drives the shaft of segmental support 6 to be rotated by 90 °, and hollow piston rod 5 moves up, and makes sealing ring 25 and rotary drum conical section 7 thereon
It being tightly engaged into, compressed air introduces in rotary drum from the second inlet duct 49, and push shuttle valve component to be moved upward to extreme position, this
When, because 42 end of mandril being mounted on intermediate spool 43 is contacted with the lower plane of liqiud outlet head 23, press the first spring 15
Contracting, circumferential weld 16 are opened, and are prepared for next working cycles of seperator.
In the present embodiment, the compressed air introduced by pneumatic device pushes shuttle valve component to paste drum inner wall and moves down with removal
Solid phase, the big technical problem of headroom needed for not only solving the workshop for placing centrifugal separator, and solve in rotary drum and be easy
The technical issues of remaining solid phase or sediment；It first passes through the first cylinder driving crossbeam to move down to drive hollow tube to move down, and then pushes
Shuttle valve component move down a small distance make between liqiud outlet head and shuttle valve formed an enclosure space, then by compressed air into
Enter confined space and shuttle valve component patch drum inner wall is pushed to move down with removal solid phase, so that total height of solid-liquid separating machine is able to substantially
Reduce, compared to the centrifugal separator in background technique, working depth can reduce one third or more, and it is non-that solid phase is discharged
Often easily and fast, the time of discharge solid phase is shortened；After separation of solid and liquid, without removing solid phase by dismounting drum assembly, this
The non-cutting time for not only having saved a large amount of separation of solid and liquid is separated by solid-liquid separation, every progress compared to using common channel separator
It is primary to be separated by solid-liquid separation working cycles, can at least save 20 minutes non-cutting times, and operator without directly contact solid phase or
Sediment will not pollute solid-phase material or separation product, and the present apparatus can also easily carry out incumbent firms and sterilizing in place,
