Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings, to enable those skilled in the art referring to explanation
Book text can be implemented accordingly.
A kind of urea granules screening plant, including cabinet 13, screening slideway 14, blower 8 and dust treatment system, the case
Screening slideway 14 is fixedly connected with inside body 13, screening slideway 14 is obliquely installed, and it is two layers that the screening slideway 14, which divides, and upper layer is
It is provided with the sieve 19 of several apertures, lower layer is powder channel 18, and screening 14 two sides of slideway are provided with rib 20, and the powder of lower layer is logical
Road 18 is pierced by 13 side of cabinet, and powder channel 18 exports lower part and is provided with powder collecting vessel 7, and the bottom end of sieve 19 is provided with herringbone
Shape shunting 21,21 exit of herringbone shunting are provided with particle conveyance conduit 15, and 13 top side of cabinet is provided with the first funnel
1,15 lower part of particle conveyance conduit is provided with the second funnel 16, and 16 side of the second funnel passes through in connecting rod 17 and cabinet 13
Side is fixedly connected, and is fixedly connected with blower 8 on 13 side of cabinet of 16 downside of the second funnel, 13 bottom of cabinet is provided with
Partition 11, the partition 11 is vertical with the wind direction of blower 8, and 13 lower part of cabinet is divided into the first collection space and second and received by partition 11
Collect space, first collection space is respectively arranged with close to blower 8, first collection space and the second collection space lower part
Third funnel 10 and the 4th funnel 12, the dust treatment system include exhaust fan 22, air draft pipe 3 and recovery pond 4, recovery pond
4 inside are equipped with absorbing liquid 5, and described 3 one end of air draft pipe is connected to 13 top of cabinet, and the other end is connected to 4 top of recovery pond simultaneously
4 bottom of recovery pond is extended down into, exhaust fan 22 is set on air draft pipe 3.
In this embodiment, cabinet 13 is used as frame structure, can guarantee all screening work all in cabinet
Portion carries out, and in this way keeps apart inner screen time-sharing environment and external working environment, prevents the dust of urea and meaning from influencing outer
The working environment in portion, while can will sieve the dust flown upward generated in work by dust treatment system and be retracted to recycling
It in pond 4, is recycled after being absorbed by absorbing liquid 5, the first funnel 1 is for the semi-finished product urea granules after being just granulated
Into the channel of cabinet 13, sieves slideway 14 and be used to screen out the powder in semi-finished product urea granules, the screening inclination of slideway 14 is set
It sets, upper layer is the sieve 19 for being provided with several apertures, and lower layer is powder channel 18, can be by the self weight of urea granules, along inclining
Oblique sieve 19 scrolls down through, during rolling, the powder that is attached to urea granules surface or is blended between urea granules
Face falls into the powder channel 18 of lower layer by the sieve pore of sieve 19 due to small volume, is transported to powder by powder channel 18
In collecting vessel 7, it is used for recycling and reusing, the urea granules of the large grained on upper layer to be scrolled down through along 19 surface of sieve, sieved
19 bottom of net is provided with herringbone shunting 21, and urea granules are shunted at herringbone shunting 21, to two side rolls, passes through people
The outlet in font shunting 21 enters particle conveyance conduit 15, and the rib 20 of screening 14 two sides of slideway can prevent urea granules to be scattered
Slideway 14 is sieved out, and the second funnel 16 is used to collect particle conveyance conduit 15 and collects the urea granules of coming, and blower 8 is as selection by winnowing
Capital equipment, for providing wind-force, the urea granules that the outlet of the second funnel 16 comes out are fallen downwards, because what is blown out by blower 7
Wind is caused urea granules to do parabolic motion in this way by the power of horizontal direction, due to the weight of hollow bead and residual shape particle
Relatively light, speed is bigger, falls in from farther away second collection space of blower 7, is used for reproduction, quality after the collection of the 4th funnel 12
Preferable urea granules fall in the first collection space, collect through third funnel 10 and are transported to subsequent workshop section later.
First funnel 1 and 16 outlet at bottom of the second funnel are flat mouth shape, and the outlet of flat mouth shape can make urea
A sake shape is formed when grain is fallen down, and urea granules can so more dispersed on the sieve 19 of screening slideway 14,
The wind-force that urea granules can be made to be subject to is more uniform, reaches better screening effect.
It is provided on the sieve 19 of 1 lower part of medial surface and the first funnel of first funnel 1 and the second funnel 16
One layer of rubber pad 9, urea granules are fallen from above, and rubber pad 9 can play certain buffer function, prevent urea granules again
It is broken.
It is toroidal at the suction opening 2 at 13 top of cabinet, toroidal has the function of gas collection, can play more
The effect of good sucking dust.
4 side of recovery pond is provided with probe tube 6, for being sampled detection to the absorbing liquid inside recovery pond 4, examines
Its saturation degree is surveyed, so that the absorbing liquid of saturation is discharged in time, adds new absorbing liquid.
The tilt angle of the screening slideway 14 is 20 ° -25 °, can guarantee that urea granules smoothly scroll down through and unlikely
It is too fast in speed, it can achieve preferable screening effect.
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art,
Other modifications may be easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
It is not limited to specific details and legend shown and described herein with novel.
