Definitions

  • the subject invention relates to a device for cleaning the at least one screen belt in a paper production plant, in which the sieve belt is guided over rollers with at least one the sieve belt adjacent vacuum chamber and at least one in the vacuum chamber arranged spray nozzle, through which a Cleaning liquid, especially water, can be applied.
  • From US no. 6,099,691 A is a device for cleaning the sieve belt a plant for paper production known, which consists of four vacuum chambers consists of two on each side of a screen belt are arranged and in which there are spray nozzles through which water is sprayed onto both surfaces of the belt, causing this is cleaned.
  • the water applied through the spray nozzles becomes fed to a separator from the vacuum chambers.
  • it will Air belt in one of the vacuum chambers to dry it.
  • the object of the invention is therefore a device for cleaning the at least one sieve belt in a system for To create paper, through which the known state of the art Disadvantages inherent in technology can be avoided.
  • This is according to the invention achieved in that the at least one vacuum chamber radially outside one of the rollers over which the screen belt goes to the beginning of the system is returned, is arranged, which is in the effective range sieve belt located in this vacuum chamber at least over a large part its length lies against this roller.
  • the at least one vacuum chamber is preferably opposite the one above the roller-guided screen belt by means of transverse to the direction of movement of the screen belt aligned sealing strips sealed. Furthermore lies preferably the sieve belt located in the area of the first vacuum chamber over the length of this vacuum chamber to the roller. It is also preferred the angle of the beam direction of the at least one in the first vacuum chamber spray nozzle arranged on a spray tube in the direction of movement of the sieve belt adjustable.
  • At least one second vacuum chamber is provided. It can the sieve belt located in the area of the first vacuum chamber its entire length against the roller and can be effective Area of the at least one second vacuum chamber area of the sieve belt rest against the roller over part of its length and over another part of its length be lifted off the roller.
  • the at least one first vacuum chamber and the at least one second vacuum chamber are connected to a common vacuum source via a suction channel, furthermore control devices are arranged between the at least one first vacuum chamber and the at least one second vacuum chamber and the vacuum source, which are designed as flaps, for example can be pivoted about axes oriented approximately at right angles, and at least part of the at least one second vacuum chamber is designed with a cross section that increases transversely to the direction of movement of the sieve belt.
  • the at least one second vacuum chamber is preferably designed with a height that increases transversely to the direction of movement of the sieve belt, if at least some of the edges of the walls of the vacuum chambers assigned to the sieve belt and oriented transversely to its direction of movement are sealed with respect to the sieve belt by means of sealing strips, the sealing strips are attached to them the edges of the walls of the vacuum chambers associated with preferably T-shaped grooves, by means of which they are pushed onto the edges of the side walls of the vacuum chambers, and at least part of the sealing strips is asymmetrical.
  • the spray tube is preferably designed with needle jet nozzles and with flat jet nozzles.
  • FIG. 1 shows a plant for paper production according to the invention, which has a first screen belt 1 and a second screen belt 2.
  • These two sieve belts 1 and 2 which are closed in themselves, are moved over a plurality of guide or deflecting rollers 11 and 21 assigned to them at the same speed of, for example, about 40 m / sec, in the region of the rollers 11a and 21a are guided to one another and are separated from one another in the region of the rollers 11b and 21b.
  • a spray nozzle 3 In the area in which the two sieve belts 1 and 2 are moved adjacent to one another there are a spray nozzle 3.
  • a plurality of suction boxes 4 are provided on both sides of the sieve belts 1 and 2.
  • a further spray nozzle 3a and a suction box 4a are arranged in the further course of the first screen belt 1.
  • cleaning devices 5 for the two screen belts 1 and 2 are arranged in the region of the guide rollers 11c and 21c.
  • the first screen belt 1 and the second screen belt 2 can be assigned further cleaning devices of this type.
  • the cleaning devices 5 are provided, which are explained below are:
  • the two vacuum chambers are attached 51 and 52 connected to a common suction channel 61, which leads to a Water separator and leads to a vacuum source.
  • the Control flaps 62 and 63 At the connection of the Suction channel 5 to the two vacuum chambers 51 and 52 are the Control flaps 62 and 63, the control flap 62 about the axis 62a and Control flap 63 can be pivoted about axis 63a perpendicular to axis 62a are.
  • the control flaps 62 and 63 can do this in the chambers 51 and 52 prevailing vacuum can be controlled.
  • the spray tube 56 is oscillating can be pushed back and forth, the amplitude of the oscillatory movement approximately the distance of the spray nozzles 57 provided in the spray tube 56 from one another is equal to.
  • the second vacuum chamber 52 formed with a sloping bottom 52a. This ensures that the suction effect of the second vacuum chamber 52 over the Width of the belt 1 is approximately the same size.
  • the filter belt 1 is in the suction area of the first Vacuum chamber 51 over its entire length to the roller 11c.
  • the upper edges are the side walls of the vacuum chambers 51 and 52 are T-shaped formed and the sealing strips 53, 54 and 55 are profiled with opposite profiles Grooves formed.
  • the sealing strips 53, 54 and 55 on the upper edges of the side walls of the vacuum chambers 51 and 52 be postponed.
  • the sealing strip 55 is opposite their groove is asymmetrical. Depending on the position of the Sealing strip 55 can be pushed onto the associated side wall the effective width of the effective range of the belt 1 second vacuum chamber 52 can be set with the values s and sl.
  • the spray tube 56a with a first group of needle jet nozzles 57a and a second group of flat jet nozzles 57b, which are mutually offset in the longitudinal direction of the spray tube 56a and the rays of which enclose an acute angle of approximately 10 ° with one another. Furthermore, the levels of the jets of the flat jet nozzles close 57b with the plane formed by the jets of the needle jet nozzles 57a an angle of about 5 °.
  • the spray tube 56 located in the vacuum chamber 51 is on this side of the sieve belt 1 is a cleaning liquid, in particular water, sprayed, which however does not pass through the sieve belt 1, but from this also due to the centrifugal force caused by the deflection of the occurs at high speed moving belt 1, on the same side emerges again and via the vacuum chamber 51 and the suction line 61 is discharged.
  • the cleaning liquid on the one Side on which the impurities are located very good efficiency is achieved.
  • To achieve an optimal Cleaning effect can be the direction of the rays of the cleaning liquid with respect to the direction of movement of the sieve belt 1 in the range of the angle ⁇ can be set.
  • the spray tube 56 performs an oscillating adjustment transversely to the direction of movement of the belt 1, whereby Sieve belt 1 is covered over its entire width by the cleaning liquid becomes.
  • the cleaning liquid removes dirt from the sieve belt 1 removed.
  • the screen belt 1 reaches the area of the second Vacuum chamber 52, which is placed between the sealing strips 54 and 55 comes into effect.
  • the sieve belt 1 is only in a first part to the roller 11c, whereas in the second part of the Roller 11c is lifted off. In this area, on the one hand, this is in the sieve belt 1 water is sucked out and on the other hand becomes air from the outside sucked in, whereby the filter belt 1 is dried.
  • the action of the vacuum chambers 51 and 52 is controlled by means of the control flaps 62 and 63 controlled. Since the second vacuum chamber 52 with one in Suction direction widening cross-section is formed across the width the sieve belt 1 achieves a constant suction effect.
  • a device is thus created which is compared to known cleaning devices has a simplified constructive training, making it cheaper to manufacture and taking up less space, which are more effective and economical as well as in operation is cheaper and with which damage to the sieve belt, which opposite Damage is very sensitive, to be avoided as far as possible.
