Definitions

  • the invention relates to a device for plan sifter consisting of a plan sifter screen, which has a sieve box with a base plate and fine material discharge, an insert screen frame and freely movable cleaning screens. has elements.
  • a plan sifter especially the large plan sifter or square plan sifter, is a large cube shape with large surface 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 wall 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. As a disadvantage, the movement also creates an audible noise.
  • Sieve cleaning pieces made of plastic in various forms are also known and work in the same way.
  • plan sifters work. For example, a freshly covered screen frame regularly works better, since not only the wear on the covering but also the degree of tension in the screen fabric is important. Experience shows, however, that a plan sifter has natural performance limits even in the best condition.
  • the intensity of the oscillating movement that is to say the maximum acceleration, is also limited, on the one hand by the maximum permissible forces in the plan sifter housing, and on the other hand by the movement behavior of the goods. Accelerating forces that are too strong impede the free flow of the material.
  • the performance data are given.
  • the object of the invention was now to develop a concept which allows an increase in performance for a given screen box volume, but which is intended to improve handling and in particular the complex of questions of cleaning.
  • the solution according to the invention is characterized in that the screen frame is only provided with a one-sided covering and preferably has at least in one direction web divisions for the formation of a Corresponding number of cleaning fields for screen and base plate, the cleaning element (s) lying on the base plate being or being insertable into the cleaning field (s).
  • the sieve box and sieve frame preferably have matching web strip subdivisions, for a two-sided fines product discharge.
  • the sieve frame can be provided with additional transverse subdivisions to form a plurality of cleaning fields and a corresponding number of cleaning elements, for example 2-9, preferably 6-12, cleaning fields with a preferably approximately square shape being formed.
  • the insert screen frame is very particularly preferably designed as a metal frame, especially as an aluminum or light metal frame.
  • the new insert sieve frame should have sufficient inherent rigidity.
  • the insert sieve frame can now be cleaned with ease for the first time because it can be easily removed from the sieve box and especially because the sieve mesh can now be cleaned on both sides with little effort, for example by brushing or compressed air. If the insert frame is made of metal, this part can also be treated completely separately with water, hot steam, etc., which was previously difficult due to the wooden construction.
  • the sieve frame with the sieve fabric closes the sieve box flush at the top.
  • the result is a clean tension of the stacks and stable stacks.
  • the insert screen frame is also possible to design the insert screen frame as a metal-wood composite, but this is disadvantageous in terms of cost.
  • the sieve frame and sieve box are preferably matched to one another in such a way that the former can be placed loosely on or into the sieve box, or can be inserted, although a quick-release connection can still have certain advantages.
  • the screen frame is advantageously produced from light metal profiles as a welded joint.
  • the sieve box is designed in a manner known per se as a dimensionally stable and dimensionally stable wooden frame and has 1 to 3 lateral channels, the surfaces in contact with the product preferably being coated with plastic.
  • the base plate of the sieve frame can be made of metal, that is, sheet metal. In special cases, the base plate can also be made of plastic.
  • a very particularly preferred core point of the invention lies in the cleaning element itself, which can be inserted into the clearing fields lying on the base plate.
  • the cleaning element is provided with a wobble foot, which is preferably made of non-metal material, which is arranged in the region of the vertical axis of gravity of the cleaning element, for the purpose that a constant change of screen fabric cleaning and floor clearing takes place due to the corresponding wobbling movements.
  • the cleaning element is designed as a boomerang with two projecting arms which have cleaning agents for the screen fabric protruding upwards, preferably on the Cleaning element, a bottom and slot clearing nose is arranged opposite the projecting arms.
  • it is made up of three arms, with at least two arms upwards with cleaning agent for the screen fabric, and one arm having a bottom and slot clearing nose which is extended outwards.
  • a fourth embodiment it is designed with four arms, at least one arm having an elongated bottom and slot clearing nose.
  • the previous optimal function was when the arms have a roof-like cross-section with the tip upwards and the broad part downwards. This not only supports the product movement over the base plate, but also helps the cleaning element to remain 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 the bottom and screen fabric are processed equally, the screen cleaner is provided with a wobble in the middle area, so that the extreme ends of the arms next to the horizontal movement of the screen cleaner above the floor in a constant interplay of up and down movements, up and down below, edit both levels.
  • the arms are provided with a plastic impact head at their extreme ends.
  • this serves as protection for the tissue 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 cleaning element so that the element is not damaged.
  • the device has a plurality of sieve stacks arranged in a plan sifter housing, each of which consists of a larger number of sieve boxes with a base plate, sieve frame and sieve channels and have a rectangular or square shape and is characterized in that the sieve mesh covered sieve frame in relation to the sieve box are interchangeable and the sieve box above the base plate together with the sieve frame form free diarrhea and product discharge spaces can be inserted into the sieve cleaner, lying on the flat base plate, the sieve frame being designed to be rust-free to reduce the sound pressure from the source noise.
  • a noise level of a plan sifter according to the invention surprisingly resulted in only a little more than 72 dB (A), compared to 84 dB (A) with comparable plan sifters the state of the art.
  • An important measure is seen in the choice of special screen cleaners, preferably made of non-metal material, and the screen frame without the previous metal support gratings for the screen fabric cleaners. There are no longer any relative movements from metal to metal.

Abstract

La présente invention concerne un tamis plan de grande taille, ou carré, (17) comportant un grand nombre de piles de cribles (16), avec par exemple plus de 20 caisses (1). Il est proposé de réaliser des cadres (3) sans grille porteuse qui seraient conçus de manière à permettre, une fois tendus, leur échange et leur pose sur ou dans leurs caisses (1). Il se forme ainsi un espace (11) entre la gaze métallique (10) et une plaque de fond plate (4) qui permet le libre passage ou l'évacuation du produit qui traverse le tamis. Les nettoyeurs de tamis (6, 6') sont posés ou insérés sur la plaque de fond plate (4). Dans un mode particulièrement préféré, les cadres (3) sont réalisés en métal. Les nettoyeurs de tamis (6, 6') nettoient la gaze métallique (10) et évacuent le produit sur la plaque de fond (4). A cet effet, des formes à 2, 3 ou 4 bras sont proposées.
