Abstract
The invention provides a vibrating screen which is simple in structure and capable of effectively collecting dust. The vibrating screen comprises a screen body with a feed inlet, a discharge outlet and a dust suction inlet. The dust suction inlet is arranged at the bottom of the screen body which is arranged on a rack. Three layers of screen cloth are arranged in the screen body sequentially from top to bottom, meshes are formed in the first-layer screen cloth and the second-layer screen cloth respectively, and the diameter of the meshes of the first-layer screen cloth is larger than that of the meshes of the second-layer screen cloth. The second-layer screen cloth is arranged in the screen body obliquely, and the discharge outlet is arranged between the first-layer screen cloth and the second-layer screen cloth. The three layers of screen cloth are arranged in the screen body, and an air suction device is mounted at the 'dust' outlet (dust suction inlet) at the bottom of an existing vibration screen to suck the 'dust' and granules and send the 'dust' and granules to a dust collector, so that the 'dust' adsorbed onto the surface of PBT (polybutylene terephthalate) is reduced, and the 'dust' is prevented from falling in air or returning to PBT products.
Description
Technical field
The present invention relates to polymeric material field, relate in particular to the improvement to vibratory sieve in production line.
Background technology
Polybutylene terephthalate (PBT) (PBT) is in tackify process, because plastic pellet ceaselessly rubs with the inwall of the high-temperature vacuum reactor rotating, produce a small amount of " dust " and tiny plastic pellet, these " dust " and plastic pellet are blended in PBT, when client produces optical cable loose tube, because viscosity is different, make loose sleeve pipe occur enclosed mass or rough problem, affect stranding effect, serious meeting makes loose sleeve pipe cracking.Therefore, PBT must remove " dust " before packing.In prior art, generally with vibratory sieve, vibrate, little plastic pellet is screened out, also have part " dust " to be screened out simultaneously.But still have on the plastic pellet of part " dust " absorption, the optical cable loose tube of producing is brought to hidden danger.When vibration, can produce " dust " and descend slowly and lightly in air simultaneously, affect vibratory sieve surrounding environment, also may waft again in product, affect product quality.
Summary of the invention
The present invention is directed to above problem, provide a kind of simple in structure, effectively collect the vibratory sieve of dust.
Technical scheme of the present invention is: comprise there is charging aperture, the sieve nest of discharging opening and suction port, described suction port is located at the bottom of described sieve nest, described sieve nest is located in frame; In described sieve nest, be provided with successively from top to bottom three layers of screen cloth, on first and second layer of screen cloth, be respectively equipped with sieve aperture, the screen-aperture of ground floor screen cloth is greater than the screen-aperture of second layer screen cloth; Second layer screen cloth tilts to be located in described sieve nest, and described discharging opening is between ground floor screen cloth and second layer screen cloth.
Also comprise air intake device, described air intake device connects described suction port.
The present invention arranges three layers of screen cloth in sieve nest, first and second layer is provided with sieve aperture, in vibration processes, stay ground floor and be larger particle and like a chain of pearls or a string of beads, what stay the second layer is qualified particle, in vibrating from discharging opening to finished container by inclined-plane, tiny particle comprises that " dust " fall the 3rd layer.Simultaneously in the bottom of existing vibratory sieve " dust " outlet (suction port) locates, air intake device is installed, " dust " and granule are siphoned away, deliver in dust arrester, so both reduced " dust " on absorption PBT surface, and also avoided " dust " to descend slowly and lightly in air or got back in PBT product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, 1 is sieve nest, the 11st, and charging aperture, the 12nd, observation panel, the 13rd, discharging opening, the 14th, suction port, the 2nd, feed hopper, the 3rd, frame, the 4th, vibrating motor, the 5th, spring, the 61st, ground floor screen cloth, the 62nd, second layer screen cloth, 63 is the 3rd layer of screen cloth, the 7th, air intake device.
The specific embodiment
The present invention as shown in Figure 1, comprise there is charging aperture 11, the sieve nest 1 of discharging opening 13 and suction port 14, on charging aperture 11, be connected with feed hopper 2, described suction port 14 is located at the bottom of described sieve nest 1, on sieve nest 1, be also provided with observation panel 12, described sieve nest 1 is located in frame 3, is also provided with vibrating motor 4 and spring 5 in frame 3, is positioned at the below of sieve nest 1; In described sieve nest 1, be provided with successively from top to bottom three layers of screen cloth (being ground floor screen cloth 61, second layer screen cloth 62 and the 3rd layer of screen cloth 63), on first and second layer of screen cloth, be respectively equipped with sieve aperture, the screen-aperture of ground floor screen cloth 61 is greater than the screen-aperture of second layer screen cloth 62, make to stay in vibration processes ground floor and be larger particle and like a chain of pearls or a string of beads, what stay the second layer is qualified particle; Second layer screen cloth 62 tilts to be located in described sieve nest 1, described discharging opening 13 is between ground floor screen cloth 61 and second layer screen cloth 62, second layer screen cloth 62 is connected in sieve nest 1 by angle adjustable mechanism, facilitates qualified particle to enter into finished container from discharging opening 13.
Also comprise air intake device 7, described air intake device 7 connects described suction port 14, for " dust " and granule are siphoned away.
Claims (2)
1. a vibratory sieve, comprise there is charging aperture, the sieve nest of discharging opening and suction port, described suction port is located at the bottom of described sieve nest, described sieve nest is located in frame; It is characterized in that, be provided with successively from top to bottom three layers of screen cloth in described sieve nest, on first and second layer of screen cloth, be respectively equipped with sieve aperture, the screen-aperture of ground floor screen cloth is greater than the screen-aperture of second layer screen cloth; Second layer screen cloth tilts to be located in described sieve nest, and described discharging opening is between ground floor screen cloth and second layer screen cloth.
2. a kind of vibratory sieve according to claim 1, is characterized in that, also comprises air intake device, and described air intake device connects described suction port.
