Body channel 65 is passed through the lower chambers 62 of cylinder 6, and as gas is constantly passed through lower chambers 62, the gas in lower chambers 62 can push work
Plug 69 moves up, and synchronous drive piston rod 61 and pulling bag holder 4 move up, until filter bag 5 is pulled upwardly to and initially loosens by pulling bag holder 4
State；
Then motor is rotated by sprocket wheel and chain-driving main shaft 2, and main shaft 2 drives rotary drum 3, cylinder 6 and the synchronization of pulling bag holder 4 to turn
Dynamic, when 3 rotating speed of rotary drum reaches charging rotating speed, distributing device 15 starts cloth and stops when the filtrate in rotary drum 3 reaches a certain amount of
Only 15 cloth of distributing device；Then motor is made to pass through sprocket wheel and 2 high-speed rotation of chain-driving main shaft, under the action of the centrifugal force, rotary drum 3
Filtrate in interior filtrate can pass through the filter opening for being attached to the filter bag 5 on 3 inner wall of rotary drum and the filter opening on rotary drum 3, and be filtered in rotary drum 3
Solid phase in material, which is then filtered to stay and be constantly trapped on filter bag by filter bag, forms cake layer, after filtrate reaches separation requirement, makes
Motor drives main shaft 2, rotary drum 3, cylinder 6 and pulling bag holder 4 to slowly run, then by gas successively through the first connection tracheae 7 with
The duct 101 on circular passage 8, pressing plate 10, second upper chamber's gas passage 68, second between spindle through-hole connect tracheae 9
And first upper chamber's gas passage 67 be passed through the upper chamber 63 of cylinder 6, as gas is constantly passed through upper chamber 63, in upper chamber 63
Gas piston 69 can be pushed to move down, synchronous drive piston rod 61 and pulling bag holder 4 move down, until pulling bag holder 4 draws filter bag 5
To straight shape is collapsed, state through the first connection tracheae 7 and lower chambers gas passage 65 as shown in figure 3, then again lead to gas successively
The lower chambers 62 for entering cylinder 6, as gas is constantly passed through lower chambers 62, the gas in lower chambers 62 can push piston 69 to move up,
Synchronous drive piston rod 61 and pulling bag holder 4 move up, until filter bag 5 is pulled upwardly to initial relaxation state, shape by pulling bag holder 4
State makes cylinder 6 drive the lower bag mouth of filter bag 5 to move back and forth up and down by pulling bag holder 4, makes as shown in Figure 1, the above-mentioned action of repetition
Filter bag 5 generates shake and chatter, to shake off the cake layer being trapped on filter bag 5, realizes the regeneration of filter bag.
It is an advantage of the invention that：（1）The cylinder being arranged on the outside of spindle top and the gas circuit being arranged in main shaft can be real
Now pulling bag holder is moved up and down, it is simple in structure, it is convenient to install and maintain；（2）Since as long as the through-hole in main shaft meets gas
Smoothly circulation, need not be compared with high manufacturing accuracy, thus greatly reduces the production cost of main shaft；（3）Due to making in main shaft
Aperture for the through-hole of gas passage is relatively small, and then increases the intensity of main shaft so that main shaft is not easy in use
It is damaged, not only extends the service life of main shaft, but also reduce enterprise's production cost；（4）By pulling bag holder with
Be arranged between cylinder to the guide rod that is oriented to, moreover it is possible to the concentricity for greatly increasing main shaft, rotary drum and pulling bag holder three carries
The high operation stability of equipment.
