    An improved plansifter having an open trough-shaped housing (12) on which is centrally mounted an oscillation generator having a drive motor (40) and a rotary and balance weight (41) for imparting oscillation movement to the housing (12). A pair of sieve stacks (23), each having a plurality of individual sieves (4), is mounted on the floor (16) of the housing (12) stradling the oscillation generator. The housing (12) is suspended for free oscillation. In a preferred construction, the rotary unbalance weight (41) is accelerated by the drive motor (40) to operational speed in a short period of time in order to preclude adverse resonance effects. The deleterious effects which might occur to the structure as it goes through its resonance frequency during acceleration and deceleration of the rotary unbalance weight (41) can be further minimized by providing a suspension means comprising an elastic suspension element (26) at one of four positions on the housing (12). Each element (26) may include a plurality of circularly cylindrical plastic bars ( 25) extending parallelly from a point or locus of affixation on the housing (12). In one preferred embodiment, first and second ends of the bars (25) can be secured at the point or locus of affixation to the housing (12) and an external support (22) respectively by means of a plurality of facing clamping members (27, 28, 29) with facing clamping surfaces having contours (31) formed therein to accommodate and securely retain therebetween the plastic bars (25).

    I ..
    The invention relates to the classification of fine materials by size and can be used in the food, chemical, metallurgical and other industries. five
    A screening is known which includes a body, a stack of sieves disposed adjacent to each other, a vibrator, a screen installed between the stacks, and a drive. The sieving frame is made symmetrical and suspended on four supports II.
    The closest to the proposed invention in its technical essence and the achieved result is a flat sieving structure including a body fixed on packages of supports connected to the side walls of the body with fastening elements 20. The casing contains two stacks of sieves, a vibrator and a drive on the lid that covers the area between the stacks of sieves 12.
    The disadvantages of these seedlings are the difficult access to the stack of sieves, as well as the low efficiency and stability of the classification process.
    The purpose of the invention is the efficiency and stability of the classification process.

    Claims (2)
    [1]
    The goal is achieved by the fact that in a flat screening, including a case, mounted on packages of supports, connected to the sides of the case by means of fasteners, two piles of screens installed in the case, a vibrator with a drive, located in the area between the piles of screens, covered with a cover, the case sieving is made in the form of a tray at the bottom of which the drive is fixed, and the side walls of the housing are equipped with tires located at the corners. The supports are made of elastic material. Fasteners can be fixed in the bottom area of the housing. either in the middle of the sidewalls of the body, or in the sidewalls of the body in a plane passing through the center of the rasseev body. Each support consists of four round rods, and the fastening elements are provided with clamps with a form corresponding to the rods. In addition, the side walls of the hull cover half the height of the stack of sieves, and the tires have a height of 1/3 to 1/2 of the height of the stack of sieves. FIG. 1 shows a flat sieving with two piles of sieves mounted on supports, a general view; in fig. 2 is the same, side view, in FIG. 3 - the same, top view; in fig. - body, made in the form of a tray; in fig. 5 shows the fastening element in FIG. 6 - leaning on supports; in fig. 7 is a variant of suspension to the ceiling beam; in FIG. 8, a variant of suspension to the frame structure is, in FIG. 9 - flat sieving with two piles of sieves suspended on elastic supports, general view. Flat sieving 1 has a left 2 and right 3 piles of individual sieves k. Both piles have an upper closure 5 with inlets 6 that are connected through elastic cuffs 7 to the corresponding product feeding elements 8. The discharge UNITS of racks 9 which are connected to stationary downpipes 11 through elastic cuffs 10. In the left sieve stack, For example, for ten sieves, 2 inlet ports 6 are in operation. The right stack, the sieve is fed only from one supply pipe of product 8. From this, different load conditions arise between the right 3 and left .2 sieve stacks. The flat screening body 12 is made in the form of an open up tray (.fig.) And has side walls 13, as well as a solid bottom I. Section 15 of the drive installation is covered above the lid 16. At the extreme four corners there is one bus 17 to hold the stack of sieves. The tires are fastened with a screw 18. Case 12 rests on four straight supports 19, which are held in the upper fasteners 20 directly on the side walls 13 of the sieving body, and in the lower fastened directly on the bottom of fasteners 21 The upper fasteners 20 are fixed on the side wall 13 through the wing flange 22 and four screws 23. The supports 19 consist of four plastic rods 2k assembled in one package by means of fasteners 20 and 21. The fastening element 20 comprises a clamping plate 2 made of three parts 5, the middle clamping member 26 and the clamping backplate 27, which are clamped together with a screw 28. All clamping parts have circular recesses 29- molded respectively by plastic rods 24. The rods have fiberglass inside, extending in the longitudinal direction and laid in a special artificial resin. Bottom fasteners 21 have a structure similar to the upper, and through leg 30 are mounted on a foundation, the four legs are not connected to each other. The required number of sieves (the optimal number is between 10-15) is clamped by means of clamping rods 31, screw 32 and safety screw 33. The height of section 15 is approximately 2/3 of the height of the largest stack of sieves. The drive motor 3 is installed at the bottom 1 of the housing in section 15 and, via a belt pulley 35, is associated with an imbalance of carbon dioxide, which is located in bearings 37 and 38 on the lid and bottom of section 15. The imbalance consists of a body 39, in which whether lead is welded. For special cases, an axial imbalance 36 is provided by means of clamping rings Q on the shaft 41. Depending on the purpose of the application, as well as on the existing production conditions, the sieving can be mounted on elastic supports, or suspended as a free vibrator on the frame structure. ceiling elements. Flat sieving works as follows. . A stack of the required number of sieves is completed and clamped by means of clamping rods 31, which can be set aside to replace the sieves. When starting the engine 3, an imbalance 36 is rotated, causing oscillating sieving along an arc in its own plane. Through the inlets 6, the material to be classified is fed to the sieves. The classified material is unloaded through the discharge units. The lotus form of the body provides quick access to individual sieves for their replacement or cleaning. The stack of screens is fully visible, which allows to control the classification process. Affordability and controllability of screening are improved by making the side walls of the housing angled outwards. The reduced dimensions of the hull and the installation of a cable at the bottom allow the center of gravity of the whole structure to be lowered. All the above design features of the flat sieving make it more reliable and simple, and also provide high quality classification. Claim 1. Flat sieve, comprising a cusp fixed on packages of supports connected to the sides of the case with fasteners, two headbands installed in the case, a vibrator with a drive located on the section between the piles of sieves covered with a lid, characterized in that, in order to increase the efficiency and stability of the classification process, the scatter casing is made in the form of a tray, at the bottom of which the drive is fixed, and the side walls of the casing are equipped with tires located at the corners, while the supports are made of astichnogo, material. 2. Rassev according to claim 1, characterized in that the fastening elements are fixed in the zone of the bottom of the case. 3. The reshuffling of claim 1, of which the fastening elements are fastened in the middle of the sidewalls of the case. .
