Definitions
- the invention relates to a plan sifter for the mechanical separation of piece goods of different piece or grain sizes into selectable size classes.
- a plan sifter for the mechanical separation of piece goods of different piece or grain sizes into selectable size classes.
- Such a plan sifter is known to be equipped with a screen box inclined more or less against a horizontal comparison plane, in which one or more screens with different mesh sizes are inserted.
- the screen box has at least one raw material inlet. At least one material outlet is then provided for the screened material.
- the sieve box carries out an oscillating movement, as a result of which the material subjected to the sieving moves from the inlet to the outlet or the outlets of the sieve box.
- the invention seeks to remedy this.
- bie invention as defined in the claims, particularly in the characterizing part of claim 1 or claim 2, solves the problem of a plan sifter having a simplest possible mounting of the screen box, as well as extremely simple Siebkastenantrieb even for relatively g horses Siebkastenkombinationen of very powerful plansifters to create by the drive mediating the oscillating movement also serves at least partially as a suspension, the propagation of the oscillating movement to the environment of the plan sifter system is prevented by compensating for the vibrations in the system itself.
- Vibration compensation is achieved, which is further improved by using flyweights arranged on the shafts as antagonists with regard to the respective instantaneous movement of the sieve boxes.
- the plan sifter according to the invention has the further advantage that the guiding of the end or ends of the sieve boxes facing away from the respective shaft can be carried out as simply as possible by means of suspensions, supports, bearings or the like, because seen in the longitudinal direction of the sieve boxes Longitudinal as well as transverse and
- Transverse movement to both composite movement of the respective distal end of the screen box is determined by the drive from the drive by the desired screen material run. Further advantages are also mentioned in connection with the description of the figures. Seen overall, the invention is characterized by simplification, cheaper, improvement in quality and the desired freedom from maintenance, as well as by error elimination with respect to vibration propagation, while simultaneously improving the smoothness of even large plan sifter units. By closely interacting the drive device with the vibrating parts while simultaneously using the drive device as an essential holder for these parts, a new path in plan sifter construction is taken, which not only simplifies but also makes the plan sifter more compact.
- This plan sifter contains two screen boxes 1 and 2 arranged one above the other, an upper screen box (1) and a lower screen box (2). They are designed as closed sieve boxes and have a similar design. Corresponding parts of the sieve boxes are designated with the same reference numbers below.

Between the upper edge of this partition wall 27 and the front wall 29 of the upper screen box 1 one of the inlet openings 18 is provided for the lower screen box 2. Under this opening 18, an inlet opening 30 is arranged in the ceiling 10 of the lower screen box 2 for the raw material to be treated in the lower screen box 2.
- the respective intermediate floor 11 of the screen box 1 or 2 contains two screens 32 and 33 lying next to one another. The type of screens and the size of their meshes can be selected in accordance with the respective purpose.
- the screens 32 and 33 are accessible or exchangeable through openings (not shown) in the side walls of the screen boxes 1 and 2. The screening of raw material in the respective screen box proceeds in a manner known per se. The course of the screening is therefore not described in detail.
- the respective sieve box 1 or 2 is surrounded by a frame 60, the focus of which is approximately coincident with that of the respective sieve box.

- FIGS. 7 and 8 Another drive device 104 is shown in FIGS. 7 and 8 shown.
- the front part of the support structure 158 has two superimposed longitudinal beams 180 and 181, which are provided with bearings 182 for two shafts 183 and 184.
- the spacing of the carriers 180 and 181 from one another is substantially smaller than the height of the support structure 158, so that the drive shafts 183 and 184 can be made short.
- On the lower ends of the shafts projecting from the lower bearings 188, 135 and 186 are placed, which are wrapped in a tension element 169, which also wraps around the disk on the drive motor 187.
- the drive motor 187 drives the shafts 183 and 184 in the same direction.
- the part of the shafts 183 and 184 protruding from the upper bearings 182 is each provided with an offset 190 (also FIG. 8) which act as an eccentric.
- This offset 190 lies in a bearing 191 which is surrounded by a sleeve 192.
- This sleeve 192 is attached to the underside of the flange 161 of the frame 160, which is connected to the sieve box 101 and 102, respectively.
- the advantage of this embodiment of the drive device 104 over the drive device according to FIGS. 4 to 6 is that only the end part or offset 190 of the short shafts 183 and 184 has to be inserted into the sleeves 192 on the flange 161. In the first embodiment of the drive device, approximately half the length of the shaft 162 or 163 had to be passed through the flange 161, which in practice caused problems can prepare.
- Shafts 183 and 184 are provided with flyweights 193 and 194, of which the first flyweights 193 are located on the upstanding part of shafts 183 and 184.
- the second flywheel weights 194 are attached to that part of the shafts 183 and 184 which is located between the supports 180 and 181 and thus between the upper and lower bearing points 182 and 188.
- the respective swing weight 193 or 194 has a support disk 195 which is attached to the shaft 183 or 184 via a hub.
- the support disc 195 is provided with holes through which fasteners 196 for flat fittings 197 pass.
- These flat shaped pieces 197 (FIG. 9) have the shape of segments with openings 199 for the fastening elements 196.
- the size of the central angle alpha of the segment 197 is selected in accordance with the desired unbalance.
- the size of the imbalance of such swing weights 193 and 194 can also be influenced by the number of fittings 197 attached to the support plate 195.
- the raw material is introduced into the common filling opening 123 when the plan sifter is started, where the ratio of the quantities of the raw material fed to the individual sieve boxes 101 and 102 is determined by the position of the distribution flap 119.
- the raw material is moving then through the respective inlet pipe 116 to the inlet openings 118, where the quantity of the raw material fed to the respective sieving unit 105 to 107 is determined with the aid of the presetting flap 114 and the blocking flaps 117.
- the first sieving unit 105 reaches the raw material via the inlet opening 118 on the far right. This raw material then reaches the sieves 132 and 133 which are inserted in the intermediate base 111 of this sieving unit 105.
- the smaller constituents of the raw material fall through the meshes of the sieves 132 and 133 and reach the bottom 112 of this sieving unit 105. Since the entire sieve box 101 or 102 has a slight inclination and since all intermediate floors 111 and floors 112 run parallel to it, the material moves as a result of the circular oscillating movements of the sieve boxes 101 and 102 caused by the drive device 104 against the ejection part 120 of the plan sifter. Pieces of the material that did not fall through the sieves 132 and 133 reach the level of the intermediate floor 101 as far as the discharge section 120 of the sieve box 101 and 102, respectively.
- the width of the flow of these pieces which extends across the entire width of the sieving unit 105 in the middle part of the sieve box, is reduced in the ejection section 120 of the sieving unit by the converging walls 135 and 136 and occurs in the region of the rear edges 141 and 142 of these 135 and 136 into the outlet channel 143 for the coarse fraction.
- the coarse passes through this outlet channel 143 Fraction up to the corresponding first outlet nozzle 121 on the outside of the sieve box 101 or 102.
- the flow of the fine fraction initially also extends over the entire width of the sieve unit 105.
- the discharge section 120 there is the plow-shaped body 145 arranged in the center, which forms the Stream divided into two sub-streams of the fine fraction.
- this body 145 deflects these partial flows to the side. Since there are no side walls on the bottom of the sieve unit 105 in this area of the discharge section 120, the partial flows of the fine fraction from this sieve unit 105 fall out into the lateral outlet channels 150 and 151. As a result, they reach the corresponding second outlet connection 122 of the sieve boxes, which is located on the underside thereof.
- the raw material enters the middle sieving unit 106 through the middle inlet opening 118 and then between the front wall 124 and the partition wall 127. After the raw material has passed through the opening 128 in the bottom 112, it reaches the sieves 132 and 133 of the middle sieving unit 106
- the separation process here is the same as for the first sieving unit 105.
- the raw material enters the third sieving unit 107 through the left filling opening 118 and through the openings 130 and 131.
- the separation process is essentially the same as for the two previous sieving units 105 and 106. The only one The difference here is that the fine fraction goes directly to the corresponding second outlet connection 122 arrives.
- the screen box is set in a circular oscillating motion by the eccentrics 166 or bends 190.
- the respective sieve box hangs on pendulum rods 103.
- the sieve box swings about sc in the steady state, as if it were stored approximately in the middle. This means that one half of the sieve box, for example the half that extends from the eccentric to the said central point of the sieve box, carries out a circular movement in one direction, while the other half of the sieve box carries out an opposite circular movement.
- the raw material in the first half of the screen box is moved in a circular direction, while in the second half of the screen box it is moved in the opposite direction.
- This causes thorough mixing of the raw material.
- the diameter of the circles that the screenings carry out decreases from the beginning of the screen box to its middle point, while behind this center the diameter of the circular movement increases again.
- the flywheels 172, 173, 193 and 194 balance those loads on the shafts 162, 163, 183 and 184 which are caused by the drive of the sieve boxes 101 and 102 connected to this is caused.
- two systems are arranged next to one another, each having a screen box 101 or 102 and a drive shaft 162, 163 or 183, 184 with the flywheel weights.
- the drive of the shafts is carried out by the motor by means of toothed belts, chains or the like.
