Abstract
The utility discloses an air-intake adjusting device of a silicon-carbide fine power classifier, belonging to the technical field of silicon-carbide fine power classification. The device comprises an air-intake pipe connected with a secondary air-intake device of the silicon-carbide fine power classifier, and a hole plate is fixed on a terminal face of the air-intake pipe. A cover plate having through holes arranged corresponding to the positions of holes on the hole plate is disposed on the outer side of the hole plate, and the cover plate and the hole plate are connected by fasteners. The air-intake adjusting device provides effective control of the area and flowrate of the air-flow in the classification chamber, improved classification accuracy, and reduced energy consumption, thereby being suitable to be widely applied on silicon-carbide fine power classification.
Description
Technical field
The utility model relates to silicon carbide micro-powder grader technical field, relates in particular to a kind of silicon carbide micro-powder grader air intake adjusting device.
Background technology
Traditional dry type gas flow sizing machine is made up of motor, grading wheel, classification stack shell etc., and it is through the rotating speed of regulating grading wheel and is equipped with the reasonable secondary air intake and realizes the effective classification to material.But the secondary air device of traditional silicon carbide micro-powder grader all adopts the power air intake usually, is furnished with compressed air source, and this just causes in the grading room flow area and flow uncontrollable, has not only reduced effectiveness of classification, and has wasted compressed air energy sources.
The utility model content
The utility model technical problem to be solved is: a kind of silicon carbide micro-powder grader air intake adjusting device is provided, controls flow area and flow in the grading room effectively, improved effectiveness of classification, reduced energy consumption.
For solving the problems of the technologies described above; The technical scheme of the utility model is: silicon carbide micro-powder grader air intake adjusting device; Comprise the blast pipe that is connected with the secondary air device of said silicon carbide micro-powder grader, fixedly mount abacus on the end face of said blast pipe, the outside of said orifice plate is provided with cover plate; Said cover plate is provided with and the corresponding through hole in the hole site of said orifice plate, and said cover plate is connected through securing member with orifice plate.
As a kind of improvement, said blast pipe is a conical pipe, and said orifice plate is arranged at the big end of said blast pipe.
Adopted technique scheme, the beneficial effect of the utility model is: owing to designed orifice plate and cover plate, and through rotating the angle between adjustment cover plate and the orifice plate; Can cover or open the hole of varying number, obtain the air intake passage of different cross-sectional, so adjusted intake; Flow area and flow in the grading room have been controlled effectively; And this air intake adopts natural wind fully, is different from traditional power air intake, greatly reduces energy resource consumption.
Because blast pipe is a conical pipe, makes air intake more smooth and easy, the classification aspect in the grading room is more obvious, and the partition size that obtains is more reasonable.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the right view of Fig. 1;
Among the figure: 1, blast pipe, 2, orifice plate, 3, cover plate, 4, securing member, 41, holding screw, 42, nut.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Shown in Fig. 1 and Fig. 2 were common, a kind of silicon carbide micro-powder grader air intake adjusting device comprised the blast pipe 1 that is connected with the secondary air device of said silicon carbide micro-powder grader; Said blast pipe 1 is a conical pipe, fixed installation abacus 2 on the end face of said blast pipe 1, more specifically; Said orifice plate 2 is arranged at the big end of said blast pipe 1; The outside of said orifice plate 2 is provided with cover plate 3, and said cover plate 3 is provided with and the corresponding through hole in the hole site of said orifice plate 2, and said cover plate 3 is connected through securing member 4 with orifice plate 2; Usually securing member 4 is preferably holding screw 41 and nut 42, and nut 42 is welded in the inboard of orifice plate 2.
During use, earlier loosening holding screw 41, direct rotating plate 3, the angle between adjustment cover plate 3 and the orifice plate 2, the hole that can cover or open varying number obtains the air intake passage of different cross-sectional, and after adjusting, the holding screw 41 of screwing gets final product.This adjusting device makes the natural wind air quantity that gets into grader obtain adjustment, has controlled flow area and flow in the grading room effectively, and has cancelled air intake power, greatly reduces energy consumption.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the utility model.
