The utility model discloses a material distributor with material distributing and sieving dual functions. The material distributor comprises a base, a machine body and a power working pair, wherein the machine body and the power working pair are arranged on the base; a charging hopper, a box cover, an undersize material discharging hopper and an oversize material discharging hopper are arranged on the machine body from top to bottom in sequence; the power working pair comprises a motor, a shaft coupler, an open cover bearing base, a rotor and a closed cover bearing base, wherein the rotor is arranged on the open cover bearing base and the closed cover bearing base in a supported manner, and connected with the motor by the shaft coupler; sieve plates are fixedly connected on the rotor; and sieves holes are formed in a gap between the adjacent sieve plates. The material distributor has material distributing and sieving dual functions in the same device, can be used for effectively avoiding an over-crushing phenomenon of fine materials, reducing the crusher power consumption and saving the cost.

Description

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

Technical field

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

Background technology

Circulating fluidized bed boiler because of its have suitable coal extensively, mechanization and characteristics such as automaticity is higher, environmental pollution is little, since the sixties in last century, just use at China part power plant equipment successively, be generalized to fields such as thermal power generation and Coal Chemical Industry rapidly 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 the 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, participates in fragmentation otherwise cause fine particle to enter into fine crusher easily with bulky grain, the phenomenon that material is crossed pulverizing occurs, crushing is increased, also caused the increase of disintegrating machine power consumption indirectly, production cost is higher, inefficiency in small, broken bits.

The utility model content

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

The utility model is to realize 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 installed on the base are paid, wherein, feed hopper, case lid, screenings discharge bucket and the oversize discharge bucket that arranges from top to bottom on the body.

Further be, 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 installed in logical the lid on bearing block and the stifle bearing block, and be connected with motor by shaft coupling, be fixedly connected with sieve plate on the described rotor, the gap between the adjacent sieve plate forms sieve aperture, is used for little material is carried out cloth and screening.

Further be, 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 under the acting in conjunction of the rotational component of rotor and material self gravitation to the preacceleration rolling and fall, better realize cloth and screening.

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

Further be, 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 be that described base, body, feed hopper, screenings discharge bucket and oversize discharge bucket are weldment independently separately, make things convenient in the use these parts are overhauled separately or change.

Owing to adopted said structure, the beneficial effects of the utility model are: adopt the feed hopper that arranges from top to bottom, case lid, 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, big 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, in same equipment, realized the dual-use function of cloth and screening, effectively avoid tiny material to cross the phenomenon of pulverizing, more reduced the power consumption of disintegrating machine, saved cost.

The specific embodiment

In order to be expressly understood the purpose of this utility model, technical scheme and beneficial effect more, below in conjunction with accompanying drawing the utility model is described further, but protection domain of the present utility model 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 installed on the 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 the 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 installed in logical the lid on bearing block 12 and the stifle bearing block 14, and be connected with motor 10 by shaft coupling 11, be fixedly connected with sieve plate 15 on the described rotor 13, the gap between the 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 installed on the body 5, and access door 9 is arranged on the 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 the distributing device shown in the arrow among Fig. 4, fall on the 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, big 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 the sieve plate 15 in the rolling process, drops to screenings discharge bucket 2, no longer enters 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, saved cost, realized that same equipment reaches the dual-use function of cloth and screening simultaneously.
