Abstract
The utility model discloses a fixed wall type cyclone pneumatic grader which is composed of an airflow inlet (1), an airflow outlet (2), a volute casing grading chamber (3), a conical platform fixed wall (4), a barrel body (5), a cone collecting chamber (6), a powder material inlet (7), a fine powder blanking opening (8) and a coarse powder blanking opening (9). Compared with the grader, the inside of which is provided with a rotating element, the utility model has wider grading object and is suitable for the combustible and explosive powder material. The utility model has the advantages of easy processing and fabrication, simple structure, high safety performance and convenient and reliable operation. The fixed wall type cyclone pneumatic grader with various dimensions can be manufactured according to the requirements of different manufacturing techniques.
Description
The utility model relates to air-flow solid isolated device from solid, particularly a kind of fixedly wall type eddy flow air classifier.
At present, can be divided into two big classes with using cyclonic unit in the interior external powder particles classification: a class is that inside has rotary part, as the spiral-flow type grader of runner, rotating vane etc.Runner friction sparking easily causes explosive powder at the grader internal explosion, and causes pipeline string fire because this class grader is in operation, and brings disaster to whole hierarchy system, thereby is not suitable in the explosion hazard powder grading technology; Another kind of is the inner fixing eddy flow air classifier of wall type of being, and existing this class eddy flow air classifier, the overwhelming majority only has grading, and there is not the collecting action of fine powder, thereby in hierarchy system, also to add the collecting device of fine powder,, make hierarchy system become very complicated as additional cyclone dust collectors, bagroom and cottrell etc.
The purpose of this utility model is to provide a kind of suitable powder scope wide, simple in structure, safe and reliable, makes classification and collects the fixedly wall type eddy flow air classifier that is integrated.
Technical solution of the present utility model is achieved in that
A kind of fixedly wall type eddy flow strength gas level machine, it is by air flow inlet (1), air stream outlet (2), spiral case grading room (3), frustum fixation wall (4), cylindrical shell (5), cone collecting chamber (6), and powder inlet (7), fine powder blanking port (8) and meal blanking port (9) are formed.Spiral case grading room (3) side is provided with air flow inlet (1), the top of grading room (3) is provided with powder inlet (7), the bottom of grading room is provided with meal blanking port (9), cylindrical shell (5) is installed in the middle of grading room (3), be welded with frustum fixation wall (4) on this cylindrical shell (5) outer wall, this frustum fixation wall (4) fixes with the bottom of grading room (3), cylindrical shell (5) leaves a fixed gap with grading room (3) top, in the middle of cylindrical shell (5), insert airflow outlet pipe (2), this airflow outlet pipe (2) is fixed with the grading room welded top, cylindrical shell (5) below links cone collecting chamber (6), and this cone collecting chamber (6) below links fine powder blanking port (8).Frustum fixation wall (4) also can be made into the billiard table fixation wall in the utility model.The utility model course of work is as follows: air-flow enters spiral case formation from inlet (1) and is rotated into grading room (3), powder is sent into grading room from grading room top powder inlet (7), mix mutually with swirling eddy, bulky grain at first is separated, and falls to be collected from grading room (3) bottom meal blanking port (9); And middle small particle with swirling eddy through frustum fixation wall (4) cylindrical shell (5) and the cone collecting chamber (6) of entering suitable for reading, continuing rotation separates, outside in the eddy flow, small particle is collected and falls in the fine powder blanking port (8) in a large amount of, and a small amount of minuteness particle rises with interior eddy flow, discharge from air stream outlet (2), collected powder is the classification required product in the blanking port (8).
The utlity model has following advantage:
1. compare with the grader that inside has rotatable parts, the classification object is more extensive, both has been applicable to general powder, is applicable to explosive flammable powder again, as powders such as aluminium powders.
2. inside is fixation wall, is easy to processing and manufacturing than rotatable parts, simple structure, and product cost is relatively low.
3. spiral case makes it air-flow rotation and compares with the rotation of rotatable parts rotating band moving air flow, and the security performance height moves convenient and reliable.
4. the utility model also can be according to the different requirements with particle size range of various processes needs, and the adjustment component size produces the fixedly wall type eddy flow air classifier of multiple different size.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is embodiment 1 structural representation.
Fig. 2 is embodiment 2 front views.
Fig. 3 is embodiment 2 vertical views.
As shown in Figure 1, and with reference to Fig. 2, Fig. 3.The course of work of the present utility model is: air-flow 1 enters spiral case from entering the mouth, rotate into grading room 3, powder is sent into grading room 3 from grading room top powder inlet 7, mix mutually with swirling eddy, in this grading room 3, powder is subjected to centrifugal action, and bulky grain at first is separated, and falls to be collected from grading room 3 bottom meal blanking ports 9.Through frustum fixation wall 4 cylindrical shell 5 and the cone collecting chambers 6 of entering suitable for reading, rotation separates once more with swirling eddy in middle small particle continuation.In the eddy flow, a large amount of middle small particles are collected in the fine powder blanking port 8 outside, and a small amount of minuteness particle rises with interior eddy flow, discharges from air stream outlet 2 with air-flow.Collected powder is the qualified products of classification desired particle size range in the blanking port 8.
As Fig. 2, shown in Figure 3.Except frustum fixation wall 4 being changed into the billiard table fixation wall, other each several part planform is with embodiment 1.
The utility model is series of products.By changing inner each part dimension of grader, just can produce the various fixedly wall type eddy flow air classifiers that vary in size that satisfy different process and powder particle size area requirement.
