Description

A kind of screening machine

The present invention relates to the solid material sieving machine, more particularly relate to a kind of industrial fine dressing sieve extension set.

Development along with high-tech and industry thereof, people are urgent day by day to the requirement of the screening plant of high order number, the vibratory sieve of prior art, revolve the sieve that shakes, flat screen, straight line shaker, reciprocating screen, wave sieve etc. and be difficult to all realize that fineness is the screening of the above solid powder of 500 orders.For this reason, the producer that has has to adopt the waterpower wet method to carry out sorting, but effect is undesirable, and efficient is extremely low, complex process, and some material is unsuitable for wet split in addition.The developed country that abroad has develops and can realize that fineness is a 400-500 purpose solid material screening machine, but because structural deficiency, cause production efficiency too low, can not satisfy the modern demand of producing in enormous quantities, production efficiency is lower, the equipment price costliness, more than 300 ten thousand yuan every approximately, and dust pollution is bigger, can not can both carry out sorting to all micro-solid materials.

The purpose of this invention is to provide and a kind ofly can carry out the productive rate height of sorting, screening machine effective, with low cost fine powder solid material.

Purpose of the present invention can realize by following measure: be connected with motor and reductor on hood, the screen drum that horizontal rotation is arranged on the plane of frame, motor is a variable-speed motor, central shaft passes through Motor Drive, screen drum is by being connected in the screen cloth left socle, screen frame between the screen cloth right support and the screen cloth that is connected on the screen frame constitute, be positioned at screen cloth fan blade and the whirlwind wheel that is connected in central shaft arranged, screen drum one end top is connected with feed hopper, the coarse fodder discharge bucket is arranged at other end bottom, on the screen cloth, the below has hood and fines discharge bucket respectively, the right sleeve in the centering axle outside, the left sleeve that one end is connected with drive connects screen cloth right support and screen cloth left socle respectively, and drive drives by reductor.

Purpose of the present invention also can realize by following measure: frame is provided with the air-introduced machine interface: screen drum and horizontal plane of frame are and are horizontally disposed with; The outside of screen cloth left socle, screen cloth right support is connected with left sealing device and right sealing device respectively.

Screen cloth of the present invention is fixed on two semi-cylindrical screen frames, screen frame is designed to horizontal rotation shape, the inside and outside skeletal fixation that screen cloth is used is on left sleeve and right sleeve, form cylindrical screen drum, left sleeve and right sleeve and the installation of spigot shaft coaxle line by two ends, be positioned on the central shaft of screen drum and be connected with the adjustable FC fan blade of array rotor, change inner blast and wind direction by adjusting the fan blade angle of inclination, or adjust blast by the rotating speed that changes the motor drives central shaft.Screen drum and central shaft are driven by two variable-speed motors respectively, can be coaxial with different rotating speeds in the same way or reverse rotation, the micro-solid material is under the effect of centrifugal force and blast, and fines enters the fines discharge bucket by screen cloth, and coarse fodder advances and enter the coarse fodder discharge bucket rapidly toward the place ahead under the blast effect.

After the micro-solid material enters screen drum, shed by the whirlwind wheel immediately, it is long-pending to avoid producing stockpile, under the effect of fan blade rotor, produce whirlwind pressure, air-flow and centrifugal force in conjunction with extraneous air-introduced machine generation, fines can sieve rapidly and fall, in addition, and in conjunction with air-introduced machine, under airflow and action of centrifugal force, sieve screen apertures is difficult for blocked, the material of screening fineness more than 500 orders, and screening efficiency is more than 95%, according to the material difference, per hour can sieve 300 kilograms to 3000 kilograms, thereby greatly improve screening production efficiency, avoid solid accumulation to cause and damaged or sieve halfway phenomenon generation to equipment, in addition, micronic dust through air-introduced machine is taken away separates recovery by deduster, reduces environmental pollution.This machine is simple in structure, and is cheap, and price is about the 5-10% of similar import screening machine.

Fig. 1 is the schematic diagram of the embodiment of the invention.

Be described further below with reference to Fig. 1:

Be connected with by electric motor driven reductor 20 in the bottom of frame 16, the left part of top, frame 16 planes is connected with the motor 1 of adjustable speed, the clutch end of this motor 1 is connected with central shaft 23, the other end of central shaft 23 is fixed in the right part of top, frame 16 planes, on central shaft 23 left sides, there is left sleeve 3 in the outside at right two ends, right sleeve 15, and install with central shaft 23 coaxial lines, the left end of right sleeve 15 connects screen cloth right support 12, the right-hand member that left end connects the left sleeve 3 of drive 2 connects screen cloth left socle 4, screen drum 21 is made of screen frame 26 that is connected in 12 of screen cloth left socle 4 and screen cloth right supports and the screen cloth 9 that is connected on the screen frame 26, the 3 groups of fan blades 8 and the whirlwind wheel 11 that are connected in central shaft 23 are arranged in the screen drum 21, the upper right side of screen drum 21 is connected with feed hopper 14, whirlwind wheel 11 is positioned at the charging aperture below, screen drum 21 lower lefts are provided with the coarse fodder outlet, there is coarse fodder discharge bucket 18 below in the coarse fodder outlet outside, on the screen drum 21, the below has the hood 10 that is provided with air-introduced machine interface 22 respectively, be provided with the fines discharge bucket 17 of fines outlet, reductor drive 19 on the reductor 20 is by chain or belt drives drive 2, screen cloth left socle 4, the outside of screen cloth right support 12 has the left sealing device 5 that is made of tapering dish and sealing rubber ring respectively, sealing device 25 is arranged.Left side sealing device 5 and right sealing device 25 are separately fixed on the frame 16, and right sealing device has grade flitch 13 in 25 outsides.
