A hinged flashboard is disposed at a material feeding port of a body of the cyclone; a dredging hole is disposed on the wall of the material feeding port at the lower part of the flashboard; the dredging hole is covered by a sealing cover; an adjustable device is mounted at the outer side of the material feeding port. The invention can realize effective mineral separation, and on-line adjustment of the material feeding amount, and is an energy-saving apparatus which can realize high-efficient separation. With the application of the cyclone, separation indexes of the cyclone, such as the circulation volume, the material feeding pressure, and the like, is correspondingly adjusted on line through the adjustment of the size of the material feeding port, which realizes simple, economical, and high-efficient mineral separation with significant economic benefits. Meanwhile, the apparatus of the invention has the advantages of simple production process, low production cost, and the like.
Description
Technical field
The present invention relates to the heavy medium cyclone that the ore dressing of a kind of screening installation technical field is used, specifically a kind of three-product cyclone one, two sections feeding mouths and two product cyclones of being adapted to
Feeding mouth is used the feeding mouth tunable arrangement to the online adjustable adjustable heavy medium cyclone of pan feeding of the feeding that enters cyclone.
Background technology
Heavy medium cyclone has been widely used in to be chosen dividing of coal.The size of heavy medium cyclone feeding mouth affects treating capacity and pressure, so be a very important parameter in structural parameters.At present, the size of heavy medium cyclone feeding mouth is fixed mode, and the on-the-spot feeding mouth size of adjusting needs to change whole cylindrical shell, and cost is high and need stop work and production, has a strong impact on the normal production of coal washery.
Summary of the invention
The defective that exists in order to solve above-mentioned prior art the invention provides a kind of feeding mouth tunable arrangement of using to the adjustable heavy medium cyclone of pan feeding of the feeding on-line control that enters cyclone.
Solve the problems of the technologies described above by the following technical solutions: the adjustable heavy medium cyclone of a kind of pan feeding, comprise cyclone body, be arranged on the pan feeding tunable arrangement in the cyclone body feeding mouth outside, described cyclone body feeding mouth place is hinged with flashboard, the feeding mouth wall place of this flashboard bottom is provided with the desilting hole, desilting is stamped seal cover outside the hole, and tunable arrangement is arranged on outside feeding mouth.
As preferred version, the folding angle of described flashboard is 0 °～90 °.
As preferred version, described pan feeding tunable arrangement is by scale plate, handle, and axle forms, and handle is fastening by axle and flashboard, and the handle other end is stuck on scale plate.
As preferred version, described desilting hole is circular hole or square hole structure.
Compared with prior art, the present invention is provided with the flashboard of rotation between 0 °～90 ° at cyclone body feeding mouth place, and by controlling the folding of flashboard, the size of on-line control feeding is carried out sorting to mineral effectively.The present invention is by adjusting the size of feeding mouth, the sorting indexs such as the corresponding online internal circulating load of having adjusted cyclone and feed pressure, make sorting become simply, economical, efficiently, remarkable in economical benefits.Having the advantages such as production technology is simple, production cost is low, is a kind of energy-saving equipment that can realize efficient separation.It is also advantageous in that significantly, adjusts online feeding mouth, improves the efficiency of separation; Adjust online feeding mouth, widened the online adjustment mode of heavy medium cyclone separation index; Separating effect strengthens, and is stronger to the ature of coal applicability.

In figure, heavy medium cyclone body 1, feeding mouth 2, pan feeding tunable arrangement 3, flashboard 4, desilting hole 5, seal cover 6, scale plate 7, handle 8, axle 9.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing.
This embodiment is the online adjustable heavy medium cyclone of a kind of pan feeding, its design philosophy is that prior art is improved, improved core is: the cyclone feeding mouth is set up the flashboard 4 that can regulate opening degree, a desilting hole 5, realizes the adjustable online of cyclone feeding with this.
Referring to Fig. 1, Fig. 2, the online adjustable heavy medium cyclone of this pan feeding is comprised of cyclone body 1, feeding mouth 2, pan feeding tunable arrangement 3.Pan feeding tunable arrangement 3 is placed in the outside of feeding mouth 2.
Referring to Fig. 3, the hinged flashboard 4 in feeding mouth place of cyclone body 1, the rotation between 0 °～90 ° of flashboard 4, the folding angle of flashboard 4 is 0 °～90 °.Flashboard 4 bottoms arrange desilting hole 5, and desilting hole 5 is circular hole or square hole structure.5 use seal cover 6 sealings of desilting hole.The folding angle of described flashboard is 0 °～90 °.
Referring to Fig. 4,5, the pan feeding tunable arrangement 3 that is positioned at feeding mouth 2 outsides is comprised of scale plate 7, handle 8, axle 9.Handle 8 is fastening by axle 9 and flashboard 4, and handle 8 other ends are stuck on the hole clipping of scale plate 7.Flashboard 4 is regulated its opening degree between 0 °～90 °, feeding is the corresponding increase of the size of the opening degree between 0 °～90 ° or minimizing with flashboard 4.The regulative mode of flashboard 4 opening degrees is to regulate by handle 8, also can adopt screw rod to regulate, and can also be other regulative modes.
The course of work of the present invention:
When cyclone body 1 work, material to be selected is tangentially fed by feeding mouth 2 and carries out sorting, and under the effect of eddy flow field, the component that in material, density is large is discharged by cyclone body 1 lower ports, the component that in material, density is little is discharged by the cyclone upper port, thereby has reached the purpose of sorting two products.The size of feeding determines by the opening degree size of flashboard 4.Because handle 8 is fastening with the flashboard 4 in feeding mouth 2 by axle 9, turning handle 8, the flashboard 4 that drives in feeding mouth 2 rotates.The hole clipping positional representation that the size of flashboard 4 rotational angles can be stuck in scale plate 7 from handle 8 out.Because the feeding size of feeding mouth 2 is determined by flashboard 4 rotational angles (opening degree), therefore as long as regulating handle 8 is stuck in the different screens of scale plate 7, also just regulated the size of the feeding of cyclone 1, thereby a kind of simple, economic, efficient on-line control mode is provided for the cyclone pan feeding is online adjustable.The effect in desilting hole 5 is materials of the alluvial of folder between cleaning flashboard 4 and feeding mouth 2, prevents jam flashboard 4, and the opening degree of flashboard 4 is regulated in impact.
Above disclosed be only specific embodiments of the invention; although the present invention discloses as above with preferred embodiment; but the present invention is not limited thereto; the changes that any person skilled in the art can think of; within not breaking away from design philosophy of the present invention and scope; the present invention is carried out various changes and retouching, within all protection scope of the present invention should being dropped on.
