Definitions

  • the invention relates to a device for cleaning screens, in particular the screens of plan sifters in mills, which act as freely movable cleaning elements in a screen box with a base plate and fine material discharge and an insert screen frame.
  • a plan sifter especially the large plan sifter or square plan sifter, is a large cube shape with large flat elements and is a special separating device, which is characteristic for the sifting of grist-like, semolina and flour-like products in the milling process technology, and for sorting different types of grains such as wheat, Rye, corn, barley, etc. is used.
  • the belt piece receives a rattling and noise-generating, intensive traveling movement due to the oscillating or circular movement of the entire plan sifter. In this way, the mesh openings with the fringed ends of the belt pieces are kept free or clean.
  • the metal grille and the metal button have an important function for the movement of the screen cleaner. The movement also creates a disadvantage as a disadvantage audible noise.
  • Sieve cleaning pieces made of plastic in various forms are also known and work in the same way.
  • plan sifter is the machine that requires the greatest effort in terms of cleaning.
  • great importance has been attached to the fact that the processing machines are as self-cleaning as possible, but can be cleaned easily and with little effort if necessary.
  • the screen frames of plan sifter screens today have a smooth floor on which the freely movable floor clearers rest. There are usually corrugated grids or support grids for support between the bottom and the covering of the screen arranged by cleaning elements. From EP-A-330 846, however, designs without corrugated mesh are already known.
  • the cleaning elements can e.g. braided belt material, which is provided with a metal button on the underside and which start to vibrate when moving over the corrugated grille, so that they hit the screen covering lightly and clean it. This also causes a significant level of noise.
  • Screen cleaner in the form of equilateral triangles US-PS 2086199
  • screen cleaners can also have the basic shape of a three-armed star, without the use of corrugated grids, and consist of elastic material.
  • these sieve cleaners are supported on the smooth sieve bottom with a stem-like foot.
  • the cantilevered arms of the star achieve a high moment of inertia during the tilting movement with a relatively low overall weight, so that sufficiently violent blows are exerted on the fabric.
  • the arms of these screen cleaners are provided with recesses that quickly clog and require additional cleaning.
  • the invention was based on the object of designing a device for cleaning sieves, in particular the sieve frame - so-called sieve cleaners - in such a way that the disadvantages of the prior art described are avoided, the handling and in particular the cleaning performance and the self-cleaning of the sieve cleaners should be improved.
  • the solution according to the invention is characterized in that the arms of the screen cleaner have a largely square cross-sectional shape with a roof-shaped elevation.
  • This roof-like elevation in turn preferably has a triangular, trapezoidal or round cross section.
  • the roof-shaped elevation of the arms prevents the regrind from sticking to the sieve cleaner (sanitation) and also improves the cleaning performance. Furthermore, the bending behavior of the arms can be adapted to the requirements and kept constant. The fact that such a solution is not obvious is shown solely by the development of screen cleaners to date, which does not reveal any comparable simple and reliable solutions.
  • the sieve cleaner can be placed on the base plate in the clearing fields.
  • the screen cleaner is provided with a wobble foot, which is preferably made of non-metal material, which is arranged in the area of the vertical axis of gravity of the screen cleaner, for the purpose that a constant change of screen fabric cleaning and floor clearing takes place due to the corresponding wobbling movements.
  • the screen cleaner is designed as a boomerang with two projecting arms which have cleaning means for the screen fabric projecting upwards, a bottom and slot clearing nose preferably being arranged on the screen cleaner opposite to the projecting arms.
  • a second embodiment it has a three-arm design, with cleaning agents for the screen fabric being arranged on at least two arms and one arm having a bottom and slot clearing nose which is extended outwards.
  • it is designed with 4 arms, with at least one arm having an elongated bottom and slot clearing nose.
  • the previous optimal function was obtained when the arms have a cross-section with a roof-shaped elevation, with the tip up and the wide part down. This not only supports the product movement over the base plate, but also helps that the screen cleaner stays clean even without product buildup.
  • the arms preferably have different cleaning agents, for example bristles or knobs and / or cleaning ribs. Floor cleaning is optimal if a sliding foot is only arranged on one arm.
  • the screen cleaner should be built slightly lower than the free height between the floor and the screen covering. So that both the bottom and the screen fabric are processed equally, the screen cleaner is provided with a wobble foot in the central area, so that the extreme ends of the arms next to the horizontal movement of the screen cleaner above the bottom in a constant interplay of up and down movements, up and down, work on both levels.
  • the arms are provided with a plastic impact head at their extreme ends.
  • this serves as protection for the fabric cleaning agent in the form of knobs or brushes, on the other hand, it enables the sieve frame to be as low as possible, and it supports the jumping movement of the sieve cleaner so that the element is not damaged.
  • the invention is particularly advantageously used in a plan sifter, the housing of which has a plurality of sieve stacks, each consisting of a larger number of sieve boxes with a base plate, sieve frame and sieve channels and having a rectangular or square shape, the sieve frames covered with sieve fabric in relation to the sieve box are interchangeable and the sieve boxes above the base plate together with the sieve frames form free diarrhea and product discharge spaces into which sieve cleaners can be placed, resting on the flat base plate, the sieve frames being designed to be rust-free to reduce the sound pressure from the source noise.
  • a screen box 1 has a plurality of discharge channels, two discharge channels for the screen repulsion or for the coarse material, 2A and 2A 'and a discharge channel 2F for the screen diarrhea or the fine material.
  • a sieve frame 3 is drawn in Figure 2 in a slightly inclined position and represents a laying movement of the sieve frame 3 on the sieve box 1.
  • the inner surface of the sieve box 1, below the sieve frame, is closed with a flat base plate 4, so that the fine material or the sieve diarrhea can only be cleared from the base plate 4 through lateral slot openings 5 (FIG. 3).
  • Sieve cleaners 6 and 6 ' are placed on the base plate 4 before the sieve frame 3 is inserted.
  • the screen cleaners 6 and 6 ' have a double function, with a scraper foot 7 the screen diarrhea on the flat base plate 4 is to be cleared out. According to the example in FIGS.
  • the sieve box 1 has web strips 12 'directly above the floor, which divide the surface of the base plate 4 into three longitudinal fields. These web strips 12 'serve primarily to increase the stability of the base plate 4.
  • the sieve frame 3 also has web strips 12 which are arranged exactly above the web strips 12 of the base plate.
  • the sieve frames additionally have transverse web strips 13. This results in the example of FIGS. 1-4 not only clearing fields B, D and F, as they result from the web strips 12 'of the base plate 4, but also by the additional subdivision of the Sieve frame 3 with the cross bars 13 additional clearing fields A, C and E.
  • the number of clearing fields (A ... F) is thus determined by the corresponding subdivisions of the insert sieve frame. It is crucial that a screen cleaner 6 is inserted in each of the common clearing fields formed in this way, which combines, both keeps the screen fabric free at the top and clears the bottom at the bottom.
  • Figures 3 and 4 each show a section of Figure 2, two screen boxes 1 are placed on top of each other.
  • a sieve frame 3 is inserted in each of the sieve boxes 1, so that a free product fall-through and discharge space 11 is formed between the sieve cloth 10 and the base plate 4, in which the sieve cleaners 6, 6 'etc. can move freely.
  • the scraper foot 7 of the screen cleaners 6, 6 ' also has the function here of removing the fine material from the cleaning field B to A or. D to C resp. F to promote E, which is easily possible because the cross bars 13 are arranged only on the sieve frame 3 and not on the base plate, so that a slot 5 'is formed at the corresponding location above the base plate.
  • the screen cleaner has a wobble foot 14 in its central area, so that the screen cleaner alternately fulfills the corresponding function once by slightly tilting movements upwards and downwards and, apart from friction and inertia forces, can move freely over the flat base plate 4.
  • a multi-armed design of the screen cleaners 6, 6 ' has the great advantage that every surface part of the screen fabric is just as in the bottom plate, up to the outermost corners is kept clean.
  • the screen cleaners ensure an optimal cleaning effect in all room directions.
  • the relatively large mass of the screen cleaner 6, 6 ', as well as the low-friction base plate support a very intensive movement of the screen cleaner 6, 6'. Even during long periods of operation, the screen cleaner is able to keep the screen mesh and base plate clean.
  • FIG. 5 shows an almost ideal clearing or cleaning field division with 9 fields, the sieve fabric 10 being shown only over half the sieve frame 3.
  • the length of a cleaning field is denoted by Län and the width by Bre. Considerable forces are used to cover the screen.
  • the sieve frames are made from thin and light metal strips, which relates in particular to the frame profiles 13, 13 'and 14.
  • the sieve frames 3 have a covering on one side only, namely the sieve fabric tension. On the opposite side, the sieve frame is open, so that the sieve fabric 10 is now equally freely accessible and easy to clean on both sides for the first time when inserting or replacing sieve frames.
  • the entire light metal frame can be produced in one piece using a metal die-casting process or, preferably, as a welded construction. It is very important that the frame allows a minimal deflection in the elastic area due to the tensile forces from the screen covering, which supports the maintenance of the tension in the screen fabric during operation. The deflection is symbolically indicated by line 15 ( Figure 5). For a screen change, a larger number of reserve screen frames 3 with different coverings must be kept ready.
  • the fact that the sieve frames have sufficient inherent rigidity with very thin frame profiles and only about half the thickness D compared to the known sieve frames means that they require little space for replacement storage, as can be seen from FIG. 6 is.
  • the web strips 12, 12 ' are expediently also produced from a corresponding metal profile, which can be a solid or hollow profile.
  • a corresponding metal profile which can be a solid or hollow profile.
  • the use of an all-metal frame has proven to be particularly advantageous. Such a frame has high flexural rigidity if a corresponding elasticity value is preferred.
  • the screen frame can also be designed as a metal, wood or metal-plastic composite.
  • FIG. 7 shows a stack of 8 sieve boxes 1 stacked one on top of the other, 3-arm sieve cleaners being inserted.
  • FIG. 8 shows an entire square plan sifter, the door 18 for a sieve compartment being removed and an entire sieve stack 16 being visible.
  • the sieve stack 16 has a sieve box 1 in a known square plan sifter 24. With the sieve box, the number of sieve boxes and sieve frames can be increased by at least 10% while maintaining the space for product conveyance above the sieve and at the same height of the plan sifter housing.
  • the entire plan sifter 17 has a swing drive, not shown, which forces all screens to have a circular movement, for which purpose the plan sifter 17 is suspended on bars 19 as a cantilever.
  • the goods are fed to the sieve stacks via inlet connectors 20, 20 'etc. and the sorted goods are discharged via discharge connectors 21, 21' etc.
  • a screen cleaner is designed as a boomerang 30, with two typical, angled cleaning arms 31, respectively. 31 '.
  • the two arms are provided with knobs 32, which have the function of screen fabric cleaning.
  • the boomerang 30 is provided in the vertical axis of gravity S with a wobble foot 14 which is a dimension "X" of a few millimeters compared to the two support feet 33 and. 33 'protrudes.
  • the boomerang 30 opposite to the two arms 31, respectively.
  • 31 ' has a bottom and slot broaching nose 34 which projects so far that the corresponding part of the fine material passes through the slot 5 can push through, as expressed in Figure 9c.
  • the boomerang 30 has an arch 36 in the direction of the bottom and slot clearing nose 34.
  • the cleaning element it is very advantageous if only the wobble foot 14 protrudes, but the support feet 33, 33 'and the lower floor clearing edge 37 of the slot and floor clearing nose 34 are of identical height. This creates a free interplay between the operational elements, and it results statistically, with very high accuracy, corresponding to approximately the same number of work assignments.
  • the knobs 32 are simultaneously in use for cleaning the screen fabric 1 and the bottom and slot clearing nose 34 for cleaning the slot 5.
  • FIG. 10 shows a 3-star 40 in which three arms 41, 41 'and 41' 'are offset by 120 ° to one another.
  • each of the arms is designed on the outside as a baffle head 42, which is the actual abutment part for the screen cleaner.
  • the arms 41, 41 'and 41' 'each have a roof-like shape in cross section.
  • FIGS. 11-11b show a 4-star 50. Arms 51 and 51 'are of identical design, arm 51''is similar, but has a cleaning rib 52 instead of the cleaning knobs. In analogy to the 3-star 40, the arm 51 '''additionally has a bottom and slot clearing nose 34. In FIG. 11a, the knobs 32 are used for cleaning the screen fabric, whereas in FIG. 11b bristles which are on the arm 51 '''are inserted, clean the screen fabric 10.
  • FIG. 11 shows the 4-star cleaner 50 in the phase of cleaning a corner of the bottom 4 of the sieve box 5 pushed, by the relative movement BS between the 4-star cleaner 50 and the plan sifter or the bottom 4 according to arrow BP. It is possible to build screen cleaners with even more arms, but these no longer have any advantages in terms of cleaning intensity.
