Abstract

The invention discloses a distributing device with dual functions of distribution and sieving. The device comprises a base, an organism and a dynamic working pair which are arranged on the base, wherein a feed hopper, a case cover, an undersized compost discharging hopper and an oversized compost discharging hopper are arranged on the organism from top to bottom; and the dynamic working pair comprises a motor, a coupler, a full-cover bearing seat, rotors and a stifle bearing seat, wherein the rotors are supported on the full-cover bearing seat and the stifle bearing seat, connected with the motor through the coupler, sieve plates are fixedly connected with the rotors, and sieve pores are formed in the space between the adjacent sieve plates. The distributing device disclosed by the invention achieves the dual functions of distributing and sieving in the same equipment, avoids the over-grinding phenomenon of fine material effectively, reduces the power consumption of a crusher, and saves the cost.

Description

Have the distributing device of cloth and screening dual-use function concurrently

Technical field

The present invention relates to a kind of distributing device, particularly a kind of distributing device that is applicable to the industrial circles such as thermal power generation and Coal Chemical Industry.

Background technology

Circulating fluidized bed boiler because of its have applicable coal extensively, mechanization and the characteristics such as automaticity is higher, environmental pollution is little, since the sixties in last century, just use at China's part power equipment successively, be generalized to rapidly the fields such as thermal power generation and Coal Chemical Industry now.

by current technology, in the coal handling system of circulating fluidized bed boiler front end, for guaranteeing the fine crusher nominal output, the fine crusher front end adopts board-like distributing device or vibrations distributing device to carry out cloth mostly, both all can only play the effect of cloth, can't the fine particle in supplied materials be sieved, and the circulating fluidized bed boiler burning is coal grain rather than coal dust, the supplied materials epigranular that provides after crusher in crushing is provided for it, otherwise easily cause fine particle to enter into fine crusher and participate in fragmentation together with bulky grain, material occurs and cross the phenomenon of pulverizing, crushing is increased, also indirectly caused the increase of disintegrating machine power consumption, production cost is higher, inefficiency in small, broken bits.

Summary of the invention

For above-mentioned deficiency, the invention provides a kind of cloth and screening dual-use function and energy-efficient distributing device of having concurrently.

The present invention realizes by such technical scheme: a kind of distributing device that has cloth and screening dual-use function concurrently, the body and the dynamically working that comprise base, be arranged on base are paid, wherein, the feed hopper, case lid, screenings discharge bucket and the oversize discharge bucket that arrange from top to bottom on body.

Be further, described dynamically working is paid and is comprised motor, shaft coupling, logical bearing block, rotor and the stifle bearing block of covering, wherein, rotor bearing is arranged on logical the lid on bearing block and stifle bearing block, and be connected with motor by shaft coupling, be fixedly connected with sieve plate on described rotor, the gap between adjacent sieve plate forms sieve aperture, is used for little material is carried out cloth and screening.

Be further, described feed hopper, dynamically working pay screenings discharge bucket and oversize discharge bucket from top to bottom ladder arrange, form the nature angle of declination, thereby can make material roll and fall to preacceleration under the acting in conjunction of the rotational component of rotor and material self gravitation, better realize cloth and screening.

Be further, described case lid comprises lid and access door, and wherein, lid is arranged on body, and access door is arranged on lid, conveniently the internal structure of distributing device is overhauled.

Be further, described dynamically working is paid and is some groups, and every group of structure is identical, disposed at equal distance arranged side by side, thus can further sieve material.

Further that described base, body, feed hopper, screenings discharge bucket and oversize discharge bucket are weldment independently separately, facilitate in use procedure these parts are overhauled separately or change.

owing to having adopted said structure, beneficial effect of the present invention is: adopt the feed hopper that arranges from top to bottom, case lid, the combining structures such as screenings discharge bucket and oversize discharge bucket, make the material of coming from feed hopper pay under the acting in conjunction of the rotational component of rotor and material self gravitation at dynamically working, material rolls to preacceleration, large material arrives the oversize discharge bucket, escape and enter disintegrating machine and carry out fragmentation, discharge the sieve aperture that little material forms between sieve plate, drop to the screenings discharge bucket, no longer enter disintegrating machine, therefore, realized the dual-use function of cloth and screening in same equipment, effectively avoided tiny material to cross the phenomenon of pulverizing, more reduced the power consumption of disintegrating machine, save cost.

The specific embodiment

In order more to be expressly understood purpose of the present invention, technical scheme and beneficial effect, the present invention is described further below in conjunction with accompanying drawing, but protection scope of the present invention is not limited in following examples.

A kind of distributing device that has cloth and screening dual-use function concurrently, the body 5 and the dynamically working that comprise base 1, are arranged on base 1 pay 6, wherein, the feed hopper 3, case lid 4, screenings discharge bucket 2 and the oversize discharge bucket 7 that arrange from top to bottom on body 5; Wherein, described dynamically working is paid 6 and is comprised motor 10, shaft coupling 11, logical bearing block 12, rotor 13 and the stifle bearing block 14 of covering, wherein, rotor 13 supportings are arranged on logical the lid on bearing block 12 and stifle bearing block 14, and be connected with motor 10 by shaft coupling 11, be fixedly connected with sieve plate 15 on described rotor 13, the gap between adjacent sieve plate 15 forms sieve aperture 16; Described feed hopper 3, dynamically working pay 6 with screenings discharge bucket 2 and oversize discharge bucket 7 from top to bottom ladder arrange, form the nature angle of declination; Described case lid 4 comprises lid 8 and access door 9, and wherein, lid 8 is arranged on body 5, and access door 9 is arranged on lid 8; Described dynamically working is paid 6 and be can be some groups, and every group of structure is identical, side by side disposed at equal distance; Described base 1, body 5, feed hopper 3, screenings discharge bucket 2 and oversize discharge bucket 7 are weldment independently separately.

when its work, at first starter motor 10, the power of motor 10 outputs is delivered to rotor 13 by shaft coupling 11, rotor 13 begins rotation, and produce a rotational component forward, material in the trend in distributing device as shown in the arrow in Fig. 4, fall on rotor 13 from the material that feed hopper 3 transportations are come, under the acting in conjunction of this rotational component and material self gravitation, material rolls forward and falls, large material arrives oversize discharge bucket 7 and therefrom discharges, enter disintegrating machine and carry out fragmentation, little material is discharged from the sieve aperture 16 between sieve plate 15 in the rolling process, drop to screenings discharge bucket 2, no longer enter disintegrating machine, thereby the mistake crushing phenomenon of having avoided tiny material to enter disintegrating machine and having occurred, correspondingly also reduced the power consumption of disintegrating machine, save cost, realized that same equipment reaches the dual-use function of cloth and screening simultaneously.
