Abstract

The utility model relates to a high-efficient material separator. A machine casing of the separator is two sides of big cylindrical casing walls having coaxially symmetrical two small cylindrical shape casing walls; the horizontally positioning directions of fine materials outlets of two small cylindrical casing walls are the same; outlets of coarse materials are connected with automatic sampling valves for materials feeding. Because symmetrical stepped outlets of fine materials are adopted, the resistance of the separator is small, air flow is uniform, sorting efficiency is high, and simultaneously, the friction of primary air inlets is reduced. Because the automatic sampling valves of materials feeding are adopted, the break output of the materials can be ensured, sampling gates can be opened for sampling at any time, and requirements of scalar materials are ensured.

Description

A kind of efficient material separator

The utility model belongs to material screening installation field, is specifically related to a kind of efficient material separator.

The present equipment that uses at home with classification of solid particles, contain one and carry a blast pipe of powder, the discharge pipe that contains fine powder material, secondary wind inleting tube and meal material outlet secretly, because the discharge pipe of fine powder material is asymmetric, air-flow is inhomogeneous, the resistance of air-flow and the efficient of classification have so just been increased, meal material exit is generally electric control valve and can not takes a sample the sorting situation of very difficult periodic analysis material in addition.

The purpose of this utility model provides a kind of classification efficiency height, and air-flow is even, the simple efficient material separator of sampling.

This efficient material selects extension set, a blast pipe 1 that has half-turn is arranged at the top of casing, there is a secondary wind inleting tube 6 bottom of casing at the sidewall of coarse fodder outlet, the offside shell wall of secondary wind inleting tube has arc-shaped guide plate 10, its casing is that the both sides of big column shell wall have two small column shell walls 4 with axial symmetry, 8, fines exhaust duct 11 on the two small column shell walls, 12 horizontally disposed directions are identical, wind porch is equipped with the arc deflector 13-1 that wind is separated in big column shell wall, the top of the coarse fodder outlet in big column shell wall and the position of arc deflector symmetry are equipped with template deflector 13-2, export 7 places at coarse fodder and are connected with the automatic blanking sample

valve.Access door

3,9 is arranged on the small column shell wall.

The automatic blanking sample valve is formed by connecting by coarse fodder inlet casing 14 and coarse fodder outlet casing 15, the upper end of two tanks junction is movably hinged with down bin gate 16, two casings of blanking goalkeeper are separated, the bottom 17 of coarse fodder inlet casing tilts and the extension certain-length to coarse fodder outlet casing, periphery cooperates with the blanking door sealing, the upper end of coarse fodder inlet casing 14 is connected with the coarse fodder outlet(discharge) flange of screening installation, and sampling gate 18 is installed on the sidewall of coarse fodder outlet casing 15.

The utlity model has following advantage:

1. owing to adopted symmetrical fines classification outlet, make the separator resistance little, air-flow is even, and efficiency of separation height has also reduced the friction of a wind porch simultaneously;

2. owing to adopted the automatic blanking sample valve, both can guarantee that material intermittently exported, can open the sampling gate sampling again at any time, guarantee the requirement of feed separation grade.

Embodiment of the present utility model respectively schemes referring to following:

Fig. 1 is a front view of the present utility model

Fig. 2 is the vertical view of Fig. 1

Fig. 3 is the front view of automatic blanking sampling gate

Fig. 4 is the vertical view of Fig. 3

From Fig. 1 and Fig. 2, can see, this efficient material separator, casing is two small column shell walls 4 of the coaxial symmetric arrangement in the both sides of big

column shell wall

2,8, access door 3 is arranged on the small column shell wall, 9, a blast pipe 1 of band half-turn is arranged at casing top, there is a secondary wind inleting tube 6 the casing bottom at coarse fodder outlet sidewall, the offside shell wall of secondary wind inleting tube has arc-shaped guide plate 10, wind porch is equipped with the arc deflector 13-1 that wind is separated in big column shell wall, the top of the coarse fodder outlet in big column shell wall and the position of arc deflector symmetry are equipped with template deflector 13-2, export 7 places at coarse fodder and be connected with the automatic blanking sample valve,

fines outlet

11,12 horizontally disposed on small column shell wall and direction identical.Whole separator is by back-up block 5 support fixation.

Can see that from Fig. 3 and Fig. 4 the automatic blanking sampling gate is formed by connecting by coarse fodder inlet casing 14 and coarse fodder outlet casing 15, be movably hinged with automatic blanking door 16 in the upper end of two tanks junction, this automatic blanking goalkeeper two tanks is separated, the upper end of coarse fodder inlet is connected with the coarse fodder outlet(discharge) flange of screening installation, the bottom 17 of coarse fodder inlet casing is to coarse fodder Way out inclination certain angle and extend certain-length, and sampling gate 18 is installed on the sidewall of coarse fodder outlet casing.20 is the lower flange of automatic blanking sampling gate.

The automatic blanking sample valve is a kind of negative pressure automatically-controlled door, does not keep negative pressure in the screening installation for a long time at material, and after material reached some, following bin gate 16 was opened automatically.

This material separator is worked under negative pressure.The gas of having carried powder material secretly enters from a blast pipe, after in a blast pipe of half-turn, carrying out a crude separation, enter great circle column type casing through arc deflector, under the guiding of the column type shell wall of casing, arc deflector, air-flow forms strong vortex in casing, corase particles in the air-flow is under the action of centrifugal force that produces that rotatablely moves, overcome the negative pressure of vortex and be thrown toward the internal face of casing and, from the corase particles outlet, discharge at last along with internal face descends; Fine grained in the air-flow is sucked by the negative pressure of vortex, and the guiding by the template deflector is rotated and discharge from the exhaust duct of the small column casing of symmetry, thereby has realized the separation of the thickness particle of powder.The gas that enters from secondary wind inleting tube, can in the upper space of corase particles outlet, form air curtain, effectively the fine particle of carrying secretly in the corase particles is blown and get back in the big column shell wall, and get back to the vortex, thereby improved thickness particle classification efficiency along big column shell wall.Requirement according to the user changes the angle position at deflector place and the size of secondary air amount, can change critical particle diameter, makes classification reach the setting requirement.Each stage material that sub-elects is opened the blanking sampling gate by deadweight, and material is intermittently exported.
