The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

As Fig. 1～shown in Figure 5, solid suspension slip screening plant of the present utility model is mainly by vibrating motor 1, the slip sieve, and vibrating mechanism, slurry vessel, bracing frame is formed.

Vibrating motor 1 is vertically mounted on the motor fixing seat 8, and motor fixing seat 8 is fixed on the slip vibration ring 7 of vibrating mechanism.Vibrating motor 1 is preferably selected the three-phase vibrating motor that itself has the adjustable eccentric piece for use, can adjust the eccentric throw of eccentric block according to the size of the required exciting force of solid suspension slip to be sieved like this, to be fit to requiring different slips to sieve to vibration.

The slip sieve comprises screen frame 2, screen cloth 3 and sieve cover 5, screen frame 2 and sieve cover on 5 the circumference and are evenly distributed with three installing holes, screw rods are installed are corresponding one by one for equally distributed three on the circumference of the slip vibration ring 7 of these three installing holes and vibrating mechanism, sieve covers the stock inlet that 5 centers have input slip to be sieved, screen frame 2 and sieve covers 5 and are fixed on three installation screw rods of slip vibration ring 7 by three hold-down nuts 6, screen cloth 3 is fixed on the lower end of screen frame 2 by two compaction hoops 4 that are adjacent to up and down, unload hold-down nut 6, just can take out sieve and cover 5 and screen frame 2, be convenient for changing screen cloth 3.Two compaction hoops 4 all are the opening circular, hoop that two ends have lug, are processed with screw on the lug, are rotary with screw 18 in the screw.During installation, external diameter is adjacent to the lower end of screen frame 2 greater than the screen cloth 3 of screen frame 2 external diameters, outside screen frame 2, put a compaction hoop 4, make screen cloth 3 between screen frame 2 and compaction hoop 4, by tighten on the compaction hoop 4 screw 18 and with screen cloth 3 bandings on the outer wall of screen frame 2 bottoms; Then, another compaction hoop 4 of banding again makes the limit of screen cloth 3 not be exposed to the outside of compaction hoop 4, guarantees not have in the vibrosieve process screen cloth chip to fall into slip.

Vibrating mechanism comprises slip vibration ring 7, be fixed in the motor fixing seat 8 on the slip vibration ring 7, be positioned over along four rubber vibration posts 9 on equally distributed four screws of slip bucket 11 upper end sidewall outer annular groove of slurry vessel, four interior hexagonal screw rods 10 screw on the slip vibration ring 7 from the top on the slip bucket 11 with slurry vessel four screws be one to one four screws (on the slip vibration ring 7 these four screws with above it fixedly screen frame 2 and sieving to cover three screw rods of 5 be to stagger, nonoverlapping, can know in conjunction with Fig. 1 and Fig. 3 and to find out) and the center screw of four rubber vibration posts 9 in, slip vibration ring 7 is fixed on the rubber vibration post 9; Other four interior hexagonal screw rods 10 screw in the center screw of four screws on the slip bucket 11 and four rubber vibration posts 9 from the below, rubber vibration post 9 is fixed on the slip bucket 11, this up and down each four interior hexagonal screw rod with slip vibration ring 7, rubber vibration post 9 and slip bucket 11 are connected as a single entity, by four rubber vibration posts 9 whole slip sieve is bearing on the slurry vessel, constitute a sifting vibrating mechanism. when the vibrating motor 1 on being installed on motor fixing seat 8 starts, 7 vibrations thereupon of slip vibration ring, the exciting force that vibrating motor 1 is produced is passed to the slip sieve, make the slip sieve carry out the vibrosieve operation, the slip that sieves is fully sieved. simultaneously, because the elastic buffer effect of four rubber vibration posts 9 makes slurry vessel and bracing frame not produce fierce vibration.

Slurry vessel comprises the slip bucket 11 with ramped bottom surface, is installed in the ball valve 12 in slip bucket 11 bottom discharging exits, is installed in the discharging mouth 13 in ball valve 12 outlets, guarantees to sieve slip smooth and easy outflow from the slip bucket easily, does not stay the dead angle.Slip bucket 11 upper end sidewalls are outside equipped with a cannelure, and fixedly four of rubber vibration post 9 screws are opened on this cannelure bottom land, and the top of bracing frame is fixed in this cannelure, and a whole set of screening plant is supported.

Present embodiment is the screening that is used for the tungsten carbide solid suspension slip behind the ball milling, consider that operating platform is higher, therefore bracing frame adopts the frame-type bracing frame, its bottom is that base plate is a square, the top is an annulus, circle on the below, big down four leg supports 14 of little " water chestnut platform shape " structure, to increase the stability of a whole set of screening plant, the bottom of three leg supports 15 on top is fixed on four leg supports, the 14 top annulus, its top then is fixed in the outer cannelure of slip bucket 11 upper end sidewalls, and directional wheel 16 and two universal wheels 17 of two deadlock structures with lock are installed on four angles of the dull and stereotyped bottom surface in four leg supports, 14 bottoms, can locate when making the screening plant operation, not operation is convenient again moves, and is convenient to maintenance and realizes that a screening plant is many spray drying tower operations.When the utility model was used for the screening operation of other solid suspension slip, bracing frame can adopt other suitable structure.

The utility model can be used for the screening operation of various heterogeneity solid suspension slips.
