Abstract

The invention relates to a material distributor, which comprises a motor or pneumatic rotary driver with output rotation shaft vertical with horizontal line, a distributing disc and a mounting support, wherein the shaft is provided with one or two distributing discs rotating horizontally, the rotary driver and the distributing disc are fixed at the bottom of a material hopper via the mounting support, the distributing disc is ellipse or oviform, the ratio between a long shaft and a short shaft is 1:0.35-0.99. The material distributor can be fixed at the top of upright container (as storage bin or bin), to uniformly distribute particle materials in the container that uniformly distributing the particles of each layer, thereby improving transmission efficiency, improving the stuff density of particles in the upright container for at least 10%, and preventing particle materials from crank caused by serious impact.

Description

Stock distributor

One, technical field

The present invention relates to a kind of distribution device of bulk cargo material shipment.

Two, background technology

The scheme of existing bulk cargo material shipment in silo or barrel is as follows: CN2532044 relates to improved disk feeder, relates to the disk feeder that the card center does not have buildup, and its improvement is at disk card middle part taper bulk cargo body is arranged.And be not suitable in stacking to large-sized silo.

Material carrier loader more general in the prior art is: vertical vessel adopts lifting appliance that charging hopper is lifted by crane the container entrance top, in bulk cargos such as granule materials are bled container from bell mouth, utilization manually installs the material footwear and in device material is paved, there is very big drawback in this type of feed, material enters reactor in the mode of vertical landing, material puts in order in a jumble, cause loading density inhomogeneous, cause the phenomenon of the overheated or channel of local temperature easily, and vertical drop is clashed into later on easily mutually, material is pulverized, the use of material is exerted an influence.

CN1412098 is the wieldy automated dispensing machine that utilizes rotating disk, comprises a fixed sturcture, and this fixed sturcture has at least one product around its axis rotation and keeps disk, also has at least one baffle plate and is used to collect the product of having selected.Described machine sets in advance at least one guide piece and is used for making container to slide, and takes an assembling position to, and the user can open baffle plate and arrive described assembling position.

Three, summary of the invention

The present invention seeks to: propose a kind of stock distributor, be installed in the charging hopper bottom to vertical vessel or feed bin shipment bulk cargo, a kind of pneumatic or electrically operated stock distributor that is applicable to the large-sized silo shipment or stacks bulk cargo is proposed, especially improve loading density, and make loading density even, and make and after falling, can not cause cracked because of bump mutually as high molecule plastic pellet etc.

The technology of the present invention solution is: stock distributor, comprise motor or pneumatic rotary drive device, the S. A. of its output is perpendicular to horizon, be provided with the material seeding dish that one to two horizontally rotates on axle, rotating driving device and material seeding dish all are fixed on bottom on the charging hopper by mounting bracket.

Improvement of the present invention is: the shape of material seeding dish is oval or avette, and the ratio of major and minor axis is 1: 0.35-0.99, especially 1: 0.6-0.80 is better.Be provided with the material seeding tooth on the surface of material seeding dish, all along oval or avette center-point excessively radially, the sum of the tooth of material seeding tooth is that the 4-24 bar is better to the tooth trace of every tooth of material seeding tooth, the even or uneven distribution on oval or avette plane.All there is radial groove in two between cog, and when the material seeding dish was placed, the more uniform groove from then on of material spilt.The cross section of vertical this groove can be triangle profile of tooth line, especially right-angled triangle teeth outline.

Its working process: (1) particle radially falls in the storage bin container with certain parabolic path, (2) material bed when surface in material drops to storage bin container, because certain speed and whereabouts mode can fully plug the gap, (3) material particles is arranged with certain orientation in container.

Operation sheet: material enters after the pneumatic material distributing box from top to bottom, because the motor that action of gravity is rotated along the centre moves down, makes granule materials be dispersed in the inside of vertical vessel uniformly through nethermost material casting dish then.

The invention has the beneficial effects as follows: device is fixed in vertical vessel (as feed bin or warehouse) top, make particulate matter can be evenly distributed in internal tank, be that every layer of particle is all relatively more even, Zhuan Yun efficient height not only, and increased the loading density of vertical vessel internal particle, can improve loading density more than 10%; And pellet can be not cracked because of violent bump.

Pneumatic rotary drive device 1, S. A. 2, plunging joint 3, pneumatic pump block 4, following material seeding dish 5, feed bin 6, feed bin push up 6-1, feed bin frame 7, pneumatic tube 8, mounting bracket 9, material seeding dish tooth 10, go up material seeding dish 11, dowel 12, connect and coil device 13, maximum gauge material seeding district 14, minimum diameter material seeding district 15.

Five, the specific embodiment

Be the structure of two material seeding dishes among Fig. 1, total is equipped with the bottom at charging hopper, fixes by mounting bracket 9 and charging hopper.Two material seeding dishes can coaxial drive or by the sleeve drive configuration, the dish that last material seeding dish and following material seeding dish are different-diameters, go up material seeding dish diameter among Fig. 1 greater than following material seeding dish, last material seeding dish central part is dowel or the radial shelf that hollows out, to material seeding dish work down, comparatively speaking, the material seeding of last material seeding dish is scattered from the central blanking of last dish, material seeding in the major diameter scope, and material seeding dish material seeding in the minor diameter scope down.

Connect and to coil the connecting strap that device 13 is perpendicular to dish, minimumly be provided with that three connecting straps will be gone up material seeding and time material seeding dish is connected, two material seeding dishes are coaxial with rotational speed.

Adopt motor or air motor to regulate the rotation actuating speed, motor adopts buncher, and air motor is by the speed of suction quantity control air motor.The radius that regulating control pellet by rotating speed broadcasts.

Material seeding dish 5 has maximum gauge material seeding district 14 and minimum diameter material seeding district 15 among Fig. 2.Lower wall does not then have hollow out.
