Abstract

The utility model relates to a cylindrical roller screen which is used to separate coarse granules and fine granules, wherein a central shaft spoke type cylinder of a traditional roller screen is changed, a steel tube ring and a frication wheel are used to form a cylinder with a plurality of steel tubes through fasteners and tube buckles, and then are arranged on two groups of rollers which are matched with the frication wheel through the frication wheel. One group of rollers is driven by a motor, then, the rollers drive the frication wheel, and thereby the cylinder and a screen mesh are rotated. The other group of rollers is manufactured into eccentric wheels and generates vibration when the rollers are rotated with the frication wheel cooperatively.

Description

The rolling cylinder sieve

Affiliated technical field:

The utility model relates to the mechanical device of the rolling cylinder sieve material type of thickness pellet separation.

Background technology

At present, producing shale brick is to have 9 band iron rings and 12 reinforcing bar welderings to make 2 meters of diameters, long 4.5 meters cylinders with rolling cylinder sieve structure, and binds screen cloth in the outside, and each band iron ring inboard is connected on 1 central shaft by 6 spokes respectively.The two ends of central shaft have bearing rack-mount, and by motor and decelerator driven rotary, thereby the rotational circle screen cloth makes its work.Blocking the pellet of sieve screen apertures is hit down by several sections flat rubber beltings playing the bar drive of rolling cylinder sieve side top.General rolling cylinder sieve is because the use of central shaft makes support must be longer than cylinder, adds that an end also will install decelerator and motor, strengthened support occupation space and material.The bearings mounted two ends of central shaft are the place of rolling cylinder sieve material turnover just again, be unfavorable for the installation of miscellaneous equipment, central shaft is connected with cylinder and must finishes by spoke, spoke all be welded superincumbent, it has increased material and welding sequence, can't be disassembled into the zero member of being convenient to transport after generally producing drum screen and being welded.

The utility model content;

Owing to rolling cylinder sieves constructional reason, cause rolling cylinder sieve dismounting difficulty, take the factory building space of increasing, increase material cost and cost of transportation.

The utility model has been cancelled central shaft and spoke in order to overcome above deficiency, uses steel pipe and steel pipe circle instead and forms cylinder jointly with friction pulley, and cylinder is placed on two groups of rollers that cooperate with friction pulley by friction pulley.Wherein one group of roller is by driven by motor, and another group is made eccentric wheel by roller, and purpose is to produce vibration with the friction pulley synergic rotation time, i.e. the bulky grain material of realization removing obstruction screen cloth can solve granule again and become doming effect, thereby improves the operating efficiency of material screening machine.The utility model fully is used in material on the critical piece----cylinder, has saved lot of materials when improving the cylinder performance.Cylinder is fitted together by fastener set, is convenient to assembly and disassembly.

The beneficial effects of the utility model are: save material, be convenient to transportation and stock.

The specific embodiment

Steel pipe circle (1) and friction pulley (4) are by the cylinder of fastener (2) and pipe thread (19), 4.5 meters of steel pipe (9) assembling growth, 2 meters of internal diameters, and screen cloth (17) is tied up cylinder inner wall (iron wire is tied up on steel pipe (9) and screen cloth fixed mount (18)) by iron wire.Friction pulley (4) the outer rubber strip (5) of riveting over increases the friction pulley coefficient of friction, and two friction pulleys (4) on the cylinder are placed on two groups of rollers (16) and eccentric roller (8) that appropriate length and span arranged.Big belt pulley roller (11) realizes that with roller (16) axis of rolling (15) is connected, big belt pulley roller (11) directly drives big belt pulley roller (11) and the common promotion of roller (16) and Na Tong and screen cloth rotation by motor (13) by V-belt (12), the cylinder that rotates drives eccentric roller (8) again.Eccentric roller (8) forces cylinder and screen cloth up-down vibration, and support (7) is installed in the both sides of fines groove respectively, is fixed by mixed earth and foundation bolt.Support laterally forms 17 with level and spends angles, allows the import of cylinder be higher than the outlet of coarse fodder.By the rotation of cylinder, coarse fodder can be rolled into the coarse fodder outlet, and eccentric roller axle (10) is connected on the support (7) with rolling bearing, bearing block (3) with roller shaft (15) two ends.Motor (13) is fixing by electric machine support (14).
