Embodiment
As shown in Fig. 1 Fig. 2, this drawer type silica sand classifying screen, four columns and pull bar is had to form cube frame, the sieve that multi-disc tilts is provided with in framework, the aperture of sieve is divided into slightly thin three kinds, in thick, thin three sieves are one group, be parallel to each other installation, three groups are at least equipped with in framework, often organize sieve and be provided with charging aperture in higher one end, charging aperture is relative with the feed pipe of elevating hopper, thin three discharge nozzles are slightly provided with at the low side of sieve, each group thick in thin three kinds of sieves low side respectively with thick in thin three discharge nozzles communicate, all spring supporting is had in the bottom of four columns, framework bottom is provided with polarizer.
Adjacent two panels sieve is parallel to each other, between distance 60-100mm be advisable, can steel brush be put in.
Fig. 4 is visible for composition graphs 3: below every a slice sieve 3, evenly many lacing wires 4 support, lacing wire 4 two ends are fixed on the screen frame (unit) 17 of sieve, sieve 3 and screen frame (unit) 17 are preferably divided into multistage, general sieve length is at about 3 meters, three sections can be divided into, dock assembling, once break down by the butt hole 18 on screen frame (unit) 17 by bolt, out of order one section can be pulled down keep in repair, very convenient.
During work, start polarizer 15, produce vibration, the silica sand of classification is needed to reach elevating hopper 7 by mechanically expecting, enter into the charging aperture 5 of each group of sieve again from each feed pipe 6, charging aperture 5 is relative with the scalping sheet 8 of this group, and silica sand enters scalping sheet 8 and takes advantage of a situation dirty, less particle sieves the middle sieve 9 fallen below, and the thinnest sand grains sieves again to be fallen on nethermost sifting screen tablet 10.The scalping sheet of each group is all pooled to a coarse sand discharge nozzle 12, and the middle sieve lower end of each group is pooled to a medium sand discharge nozzle 13, and the silica sand that can obtain three kinds of particle diameters with a fine sand discharge nozzle 14, three discharge nozzles 11 is all collected in the sifting screen tablet lower end of each group.
The second embodiment: as shown in Figure 5, this drawer type silica sand classifying screen is also furnished with air compressor 19, and compressed air is stored in inside high-pressure gasbag 20, and high-pressure gasbag 20 is connected to high-pressure air pipe 21, and high-pressure air pipe 21 front end is provided with switch 22 and shower nozzle 23.
When finding that sieve 3 has a blocking, the front portion of the hand-holdable high-pressure air pipe 21 of operating personnel, makes shower nozzle 23 aim at block part, opens switch, and gases at high pressure are gone out and can be removed blocking, and this is more quick more respectively than the cleaning of use steel brush, and can alleviate and scrape damage to sieve 3.
The third embodiment: as shown in Figure 6, this drawer type silica sand classifying screen is also furnished with air compressor 19, compressed air is stored in inside high-pressure gasbag 20, high-pressure gasbag 20 is connected to high-pressure air pipe 21, time opening valve 24 high-pressure air pipe is equipped with, the lacing wire 4 before high-pressure air pipe 21 below termination sieve 3.Fig. 8 is visible for composition graphs 7: lacing wire 4 is made for hollow tube, and inside have air flue 25, the outside of lacing wire 4 is also provided with multiple pore 26, and the angle of each pore 26 is different, and each bar lacing wire 4 is preferably interconnected.
During operation, time opening valve 24 pulsed is opened, and gases at high pressure are gone out from the pore 26 of lacing wire 4 by different angles, clear up the sieve 3 before lacing wire 4, prevents blocking.Had this covering device, classifying screen can realize unmanned or a people monitors multiple stage classifying screen, significantly can reduce manpower burden and operating cost.
