Definitions
- the invention relates to a sieve cleaner for cleaning a sieve surface of a sieve box, which contains the sieve surface and a sieve bottom.
- a screen cleaner can be adapted for cleaning a screen surface of the screen box of a Plansich ⁇ ters.
- the invention relates to a sieving unit and a method for upgrading or converting a sieve box.
- Movable sieve cleaners which can be placed on a sieve bottom of a sieve box and with the aid of which a sieve surface of the sieve box can be cleaned, are known per se.
- Such screens are stackable and can be arranged for example as a stack of sieves in sifters to sift granular to meh ⁇ celled products into various fractions and qualities to separation or NEN.
- the screen cleaners absorb the oscillating movements of the plansifter and the sieve boxes and thus move randomly around on the sieve tray, repeatedly bouncing off the sieve frame.
- Generic sieve cleaner are for example from the
- brushes are used rather for finer screen surfaces with mesh sizes in the range of, for example, 85 to 250 ym and knobs for coarser screening surfaces with mesh sizes of, for example 250 ym or more.
- Similar screen cleaners in which the cleaning takes place by knobs or brushes striking the screen surface, are also described in DE 10 2006 005 970 A1, US Pat. No. 6,095,339 A,
- EP 0 536 803 B1 EP 2 465 616 A1, WO 99/28053 A1
- WO 2010/045284 AI discloses. This sieve cleaners are composed of simp ⁇ chen geometric figures, such as balls, cylinders and polyhedra. However, tests with at least similar screen cleaners have shown that they are more likely to clog the screen surface.
- the sieve cleaner should clean the sieve surface as efficiently as possible without damaging it or the sieve frame. ene requirements for the processing of foodstuffs.
- a sieve cleaner is designed for cleaning a sieve surface of a sieve box which contains the sieve surface and a sieve bottom.
- the sieve cleaner can be designed, for example, for cleaning a sieve surface, such as a sieve fabric, a sieve box of a plan sifter.
- the sieve cleaner contains a wobble foot which extends along a main axis of the sieve cleaner and is designed such that it can be placed on the sieve bottom and the sieve cleaner can be tilted around this wobble root.
- the said main axis can be, for example, a heavy axis of the sieve cleaner.
- the sieve cleaner Minim ⁇ least includes a cleaning member having a cleaning area, wherein the or each cleaning area including a plurality of cleaning surfaces to clean the screen surface.
- the cleaning surfaces are each formed for at least a linear contact with the screen surface and separated from each other by slots formed in the cleaning region.
- a linear contact is understood here and below to mean a one-dimensional contact-in contrast to a point-like, ie, zero-dimensional, contact which exists between a rounded knot or bristle end known from the prior art and a flat screen surface.
- the Formulie ⁇ tion "at least linearly" here includes also flat, so two-dimensional contacts.
- the at least linear contact leads to the cleaning ⁇ supply surfaces during rotation about the main axis of the sieve cleaner cover an area, so two-dimensional area of the screen surface.
- a substantial proportion of the cleaning is achieved by stripping the fine material from the screen surface, which has passed through them.
- Tapping as is the case with the knobs known from the prior art, can thus rather be neglected.
- the slots formed between the starsflä ⁇ chen thereby ensure that the fines can partially pass through these slots. This prevents that the fines from the cleaning areas is merely scanned into the screen surface or that the screen surface is pushed away from Siebrei ⁇ niger due to the accumulating fines.
- the screen cleaners according to the invention thus have the advantage that they can clean the screen surface at least as well or even more efficiently than was possible from the state of the art.
- This advantage is also screening areas, especially mesh with small mesh sizes ⁇ ren, were used for the prior art screen cleaner with brushes, so especially for screen surfaces with a mesh size of less than 250 .mu.m, preferably less than
- the wobble foot can be rounded, which simplifies tipping and increases the freedom of movement of the sieve cleaner.
- the cleaning area preferably contains no brushes. Consequently, since no bristles can tear out, the screen cleaner can thereby meet hygiene requirements.
- the slots extend in a slot direction which enclose an angle with respect to the major axis of an angle which is in the range of 0 ° to 90 °, preferably 30 ° to 60 ° and more preferably 40 ° to 50, and more particularly preferably 45 °.
- Such angles provide more stripping edges, which are particularly useful in different directions of movement.
- the cleaning surfaces sweep in each case an imaginary cleaning line in a direction radial with respect to the main axis.
- the ratio of the radial distance between two adjacent cleaning lines and the radial length of the cleaning lines is in the range of 50% and 100%, more preferably 90% and 95%.
- the cleaning members in particular below nor ⁇ läuterten preferred cleaning arms may be parallel to the main axis ⁇ have a height, and the slits can be parallel to the major axis have a depth.
- the ratio between the depth of the slots and the height of the starsele ⁇ elements, in particular the cleaning arms greater than 0% and less than or equal to 20%; Preferably, the ratio is about 10%. The larger this ratio is, the lower the sliding friction between screen cleaner and screen surface and the setting of the fine material and at a given level of cleaning elements the less there is a risk of stagnation of Siebreini ⁇ gers. On the other hand, conditions that are too large would cause the fines to accumulate too much in the slots.
- the slots of one and the same cleaning element run parallel to one another.
- the screen cleaner has a central area containing the main axis with a top opposite the wobble foot, which is recessed relative to the cleaning surfaces such that it can not be brought into contact with the screen surface, in particular can not be brought into contact with a substantially flat screen surface is.
- the said top does not form a cleaning surface for cleaning the screen surface. Namely would cause this came already in the untilted state of Siebrei ⁇ niger in contact with the screen surface at the top of the middle showing off ⁇ ches existing non nistsetti against the cleaning surfaces of the tire-depth cleaning surfaces. This would lead to ei ⁇ nem braking or even clamping of the sieve cleaner between the sieve plate and sieve surface.
- the screen cleaner contains at least three cleaning ⁇ elements, in particular at least three, as described below in detail cleaning arms.
- each of the at least three cleaning elements is provided with a respective Rei ⁇ nists Kunststoff, each cleaning area including a plurality of cleaning surfaces to clean the screen surface.
- the cleaning surfaces are arranged and cleared ⁇ forms that at standstill of the Siebkastens (ie in particular in the absence of movements of the sieve box, which support the sieving) and taut strained Sieb Properties the cleaning surfaces of at least two of the cleaning elements, but not the cleaning surfaces of all cleaning elements , at the same time in contact with the screen surface are or can be brought In this case, essentially all cleaning surfaces of these cleaning elements are in contact with the screen surface or can be brought.
- substantially all means that at least 50%, preferably at least 70%, more preferably at least 90% and particularly preferably sämtli ⁇ che cleaning surfaces of said two cleaning elements in contact with the screen surface are.
- two cleaning ⁇ elements is a single cleaning surface in contact with the screen surface only. in this way, the contact with the screen surface and thus the cleaning effect can be increased.
- the screen cleaner is made of a sufficiently elastic material.
- a relatively soft polyurethane such as from an Elastollan®, which is available from BASF.
- Elastollan® is also permitted for the processing of food, such as For example, cereal or milled grain products.
- Elastic Ma ⁇ terialien have that a screen frame of the screen box is less damaged by the toast of the sieve cleaner among others the advantage.
- the screen cleaners according to the invention can be produced, for example, in an injection molding process.
- the screen cleaner at an odd ⁇ number of cleaning elements, in particular cleaning arms on.
- the number above is preferably at least three and be ⁇ Sonder preferably precisely three.
- the cleaning elements are uniformly distributed in the circumferential direction. This structure is particularly simple and enables an advantageous compromise between the cleaning effect and the clearance formed between the cleaning elements, in particular the cleaning arms. Is / are also provided with particular advantage that / the cleaning ⁇ eiementie) is provided as a cleaning arm (s) formed is / are of / the main axis extends from a central area of the sieve cleaner containing radially outwards / extend. This also contributes to the mentioned advantageous compromise.
- the cleaning surfaces are arranged in a single row along the cleaning arms. This is just ⁇ if a sufficiently low sliding friction between the screen cleaner and screen surface scored, which prevents clogging of the slots by the fines and a stoppage of the screen cleaner.
- the cleaning arms may have a length which is in the range of 5 to 15 cm, preferably 6.5 to 7.5 cm. Further, be ⁇ vorzugt the cleaning areas have a radial length, wherein the ratio of the radial length is the length of the washing arms is in the range of 50 to 100%, preferably about 85%.
- impact protectors can be arranged at the outer ends of the cleaning elements, in particular the cleaning arms. This can reduce the risk that the cleaning surfaces will wear due to contact with the screen frame.
- the impact contactors can be formed for example as reinforcements of the cleaning ⁇ elements in a direction perpendicular to the main axis.
- Sieve cleaner have at least one scraper for clearing located on the sieve bottom fines through an opening formed in a sieve frame of the sieve box clearing. ⁇ advantageous way legally disposed such Aus Hurmö réelle at the end of a cleaning supply ⁇ poor.
- the sieve cleaner is integrally formed. This he ⁇ facilitates its production and further reduces the risk of loss of individual components.
- Another aspect of the invention relates to a screening unit.
- This contains at least one sieve pan with a sieve bottom and a sieve surface, in particular a forming fabric, as well min ⁇ least one sieve cleaner, which can be placed or placed on the perforated bottom.
- the screen cleaner of the screen unit according to the invention has at least three cleaning elements, in particular three cleaning arms, with a respective cleaning area, each cleaning area having a plurality of cleaning surfaces for cleaning the screen area.
- the cleaning surfaces are arranged and designed such that when the screen box is at a standstill (ie in the absence of the movements of the screen box that support screening) and when the screen surface is stretched tightly, the cleaning surfaces of at least two of the cleaning surfaces but not the cleaning surfaces of all cleaning elements, at the same time in contact with the screen surface or can be brought, in which case substantially all cleaning surfaces of these cleaning elements are in contact with the screen surface or can be brought.
- the sieve cleaner comprises at least three cleaning members and the sieve cleaner and the screen box are designed and coordinated so that at standstill of the screen box (ie in particular the absence of the movements of the Siebkas ⁇ least that support the seven ), with a correctly clamped screen surface and at the resting of the foot on the sieve bottom swash the cleaning surfaces of all the cleaning elements a distance of less than 5 mm, preferably less than 3 mm, particularly before Trains t ⁇ have less than 1.4 mm from the screen surface. Because of this small maximum distance from the screen surface, the vertical to the screen surface, ie in particular vertical Geschwin ⁇ speed component is limited, with the cleaning surfaces impinge on the screen surface when the screen cleaner tilts around the wobble.
- the mesh size of the screen surface in particular of the screen fabric, is less than 250 ⁇ m, preferably less than 180 ⁇ m, more preferably less than 150 ⁇ m, even more preferably less than 125 ym and more preferably less than 90 ym.
