Abstract
The invention discloses a protective device of a belt type filter friction belt, which comprises a driving wheel, a bend wheel and a friction belt assembled on the bend wheel, wherein a separating board is arranged in the position between the driving wheel and the bend wheel and near to the outer circumferential surface of the bend wheel; a clearance is formed between the separating board and the friction belt on the bend wheel; and the shape of the separating board is matched with that of the end part of the bend wheel. According to the device, the separating board is arranged in the position between the driving wheel and the bend wheel and near to the outer circumferential surface of the bend wheel, so that when the bend wheel rotates counterclockwise along with the driving wheel, the slack friction belt at the left end of the bend wheel slips continuously under the guidance of the separating board rather than curls due to stacking and enters into the clearance between the driving wheel and the gummed tape, and friction belt damage is avoided accordingly. The device has a simple structure, is convenient to mount, and is steady and reliable in operation.
Description
Technical field
The present invention relates to band filter, especially a kind of band filter friction band protective device.
Background technology
Above the band filter adhesive tape filter cloth is arranged, filtrate is collected on the adhesive tape, and the adhesive tape upper surface has groove, and is middle porose, and the vacuum box of adhesive tape below vacuumizes by vavuum pump, and filtrate is taken away.Slide unit is arranged above the vacuum box, is the friction band between slide unit and the adhesive tape, because vacuum produces attraction, slide unit reduces the frictional force between vacuum box and the friction band, and the friction band reduces the frictional force of adhesive tape operation.
But, along with the adhesive tape driving wheel is rotated counterclockwise, the operation of drive adhesive tape, friction band frictionally moves by identical direction with adhesive tape, and the distance between adhesive tape driving wheel and the friction band bend wheel is closer, and the friction band is harder, in the running, friction band is easy to drop on driving wheel, with the driving wheel rotation and be squeezed between driving wheel and the adhesive tape, along with the continuous rotation of adhesive tape driving wheel, friction is with indrawn length increasing until breaking.And each time of changing friction band and slide unit about 24 to 32 hours, lose bigger.
Summary of the invention
At the deficiencies in the prior art part, the present invention aims to provide a kind of band filter friction band protective device, and when guaranteeing that the adhesive tape driving wheel is rotated counterclockwise, the friction band keeps isolating with driving wheel, and the friction band is not involved between driving wheel and the adhesive tape.
For solving the problems of the technologies described above; the technical solution used in the present invention: a kind of band filter friction band protective device; comprise driving wheel, bend wheel and be assemblied in friction band on the bend wheel; between driving wheel and bend wheel, near outside the bend wheel outer circumference surface division board is set; gapped between the friction band on division board and the bend wheel, the shape of division board and bend wheel end shape are complementary.
Adopt said apparatus, owing between driving wheel and bend wheel, near outside the bend wheel outer circumference surface division board is set, like this, when bend wheel is rotated counterclockwise with driving wheel, friction band slippage continuously under the guiding of division board that the bend wheel left end is lax, can not pile up and produce to curl and enter between driving wheel and the adhesive tape, having stopped the damage that therefore the friction band causes.
This apparatus structure is simple, is convenient to stable and reliable operation is installed.
Description of drawings
Fig. 1 is prior art friction band assembly structure schematic diagram;
Fig. 2 is structural representation of the present invention;
In the accompanying drawing: 5 adhesive tapes, 6 bolts, 7 vacuum boxs, 8 chutes are with in 4 frictions of 1 driving wheel, 2 division boards, 3 bend wheels.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
In Fig. 1, above the adhesive tape 5 filter cloth is arranged, filtrate is collected on the adhesive tape 5, and adhesive tape 5 upper surfaces have groove, and are middle porose, and the vacuum box of adhesive tape 5 belows 7 vacuumizes by vavuum pump, and filtrate is taken away.Along with adhesive tape 5 driving wheels are rotated counterclockwise, friction moves by identical direction with adhesive tape 5 with 4 frictionallies, because the distance between driving wheel 1 and the bend wheel 3 is closer, and friction is with 4 harder, in the running, friction is with 4 to be easy to drop on driving wheel 1, rotates and is squeezed between driving wheel 1 and the adhesive tape 5 with driving wheel 1 and cause damage.
In Fig. 2, between driving wheel 1 and bend wheel 3, near outside bend wheel 3 outer circumference surfaces division board 2 is set, the friction on division board 2 and the bend wheel 3 is gapped between being with 4, division board 2 curved shapes, the shape of division board 2 and bend wheel 3 end shapes are complementary; It is polytetrafluoroethylene (PTFE) that division board 2 adopts materials, corrosion-resistant, wear-resistant, coefficient of friction is less; Division board 2 is fixing by bolt 6, and bolt 6 is installed in the chute 8 of bend wheel 3.Like this, when bend wheel 3 was rotated counterclockwise with driving wheel 1, the lax friction of bend wheel 3 left ends was with 4 slippages continuously under the guiding of division board 2, can not pile up and produced to curl and enter between driving wheel 1 and the adhesive tape 5.
