A powder shifter, especially suitable for the powder shifter that the chemical industry, medicine standard sieve, it is by the chassis 2 links to each other with the fixed disk 12 of both ends of chassis, and cross the central axis 7 in the center of the fixed disk, the change-speed gear box on the central axis, install the screen cloth 15 on the fixed screen frame 13 on the outer casing 3 of change-speed gear box, the feed inlet 17 fixed on brush 14 and fixed disk on the central axis, the slag notch 1 makes up, characterized by that both ends of the central axis 7 have the same change-speed gear box separately, there is a cleaning door 19 in one end of the feed inlet 17, the central axis is at least two-section, can disconnect, the change-speed gear box makes screen cloth 15 and brush 14 produce the syntropy double-speed operation, this powder shifter has simple in construction and easily.

Description

Sieving machine

The utility model relates to a kind of sieving machine, particularly a kind of sieving machine that is used for the standard flour screening of industries such as chemical industry, medicine food.

The sieving machine that is used for the screening criteria powder at present generally is by casing, and the screen cloth in charging aperture, slag notch and the casing, axle and axle are gone up the flight of installing and formed.FTS-190 type sieving machine as the production of Jiangyin rarity pharmaceutical machine factory, central shaft runs through whole sieve nest, to lean on the helical blade on the central shaft during charging, material be sent in the screen cloth screened, can't at will clean in the screen cloth, cleaning is got up very inconvenient, screen cloth is to be fixed on the shell of sieving machine, and screen cloth can not rotate the flight that can only lean on the axle and stir material during work, sieve powder weak effect, and the complex structure of this sieving machine, the Flow of Goods and Materials weak effect.

The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and provides a kind of gearbox and clean-out door, hairbrush and screen cloth of having to produce double speed running in the same way, at least two sections of central shafts, simple in structure, just with the maintain and replace parts, screening effect is good, easy cleaning, the sieving machine that slag easily flows out.

The purpose of this utility model can reach by following measure, a kind of sieving machine, the fixed disk 12 that it is linked to each other with the casing two ends by casing 2, and went here and there the central shaft 7 at fixed disk center, and the screen cloth 15 on screen bed base 13 screen bed bases, be fixed on hairbrush 14 on the central shaft 7 and the charging aperture 17 on the fixed disk, slag notch 1 is formed.Identical gearbox is installed at the two ends that it is characterized in that central shaft respectively, is provided with clean-out door 19 at an end of charging aperture 17.

The purpose of this utility model can also reach by following measure, and a kind of sieving machine, gearbox have on central shaft 7, tooth rest 5, and axle sleeve 6 has the gear teeth 9, the ring gear 11 in the gear 10 on the tooth rest 5, gearbox, capping 4 is formed.The gear teeth 9 on the axle sleeve 6 are mutual interlocks with gear 10 and ring gear 11, and screen bed base 13 is fixed on the gear-box case 3, and central shaft 7 is formed by at least two sections, can disconnect between section and the section.

The utility model compared with prior art has following advantage: (1) since central shaft 7 be provided with gearbox make hairbrush 14 and screen cloth 15 produce in the same way the double speed running makes screening effect good.(2) owing to being provided with screen bed base 13, gear-box case 3 saved original isolated screen bed base, and screen cloth 15 can rotate with screen bed base, the structure of so promptly having simplified sieving machine makes the replacing screen cloth convenient and easy again, (3) so to intersect rotary and clean-out door diameter easily thorough when equaling the diameter cleaning of feed hopper 18 because clean-out door 19 adopts, (4) because the central shaft segmentation is very convenient when the centre can disconnect the event installation and maintenance.

Description of drawings:

Fig. 1 is the structural representation of sieving machine:

1, slag notch 2, casing 3, gear-box case 4, capping 5, tooth rest 6, axle sleeve 7, central shaft 8, belt pulley 9, the gear teeth 10, gear 11, ring gear 12, fixed disk 13, screen bed base 14, hairbrush 15, screen cloth 16, tie-plate 17, charging aperture 18, feed hopper 19, clean-out door 20, sieve door

Describe the utility model in detail below in conjunction with accompanying drawing; The fixed disk 12 that this utility model is connected as one by casing 2 and casing two ends, be respectively equipped with charging aperture 17 and slag notch 1 on the fixed disk, be connected in the axle sleeve 6 at fixed disk 12 centers, the central shaft 7 at the gear teeth 9 centers on the axle sleeve, be respectively equipped with tooth rest 5 on the central shaft, the gear of installing on the tooth rest 10, be respectively equipped with ring gear 11 in the gear-box case 3, the gear teeth 9 and gear 10 on the axle sleeve, and ring gear 11 mutual interlocks, be separately installed with screen bed base 13 on the gear-box case 3 and also can be cast into one, and the capping 4 on the gear-box case, screen cloth 15 is installed on the screen bed base, hairbrush of installing on the central shaft 14 and tie-plate 16, central shaft 7 one ends are provided with a belt pulley 8, and clean-out door 19 its diameters and feed hopper 18 equal diameters also can be greater than the feed hopper diameters.

Embodiment 2: the supporting use of this sieving machine and pulverizer, also can use separately, and when material enters sieving machine by charging aperture 17 under by the effect of pulverizer strong wind, can enter very soon and carry out screening process in the screen cloth 15.When using separately because charging aperture 17 is closer with screen cloth 15, sieving machine is installed integral inclination certain angle, also can enter the screening purpose that reaches satisfied in the screen cloth 15 very smoothly, material enters behind the screen cloth by hairbrush 14 polish-brush effects, what granularity was little can be flowed out by slag notch 1 by the big material of screen cloth 15 granularities very soon, be difficult for remaining in the screen cloth, when changing screen cloth 15, can open sieve door 20 and directly screen cloth 15 is installed on the screen bed base 13, can directly open sieve door 20 and clean-out door 19 during the cleaning sieving machine and carry out inside and outside thoroughly cleaning easily.
