Abstract
The invention discloses a detachable centrifugal fan impeller. The detachable centrifugal fan impeller is provided with an impeller shaft of a cylindrical structure. A plurality of blades which are made of metal materials and have the same included angle are evenly arrayed on the circumferential surface of the impeller shaft. A shaft hole with the two ends communicating with each other is formed in the center of the impeller shaft. A key groove is formed in the shaft hole. Insertion grooves of an L structure are formed in one side end face of the impeller shaft. One straight sides of the insertion grooves communicate with the exterior of the circumferential surface of the impeller shaft, and the other straight sides of the insertion grooves communicate with positioning holes formed in the impeller shaft. One end, on the same side as the corresponding insertion groove, of each positioning hole communicates with the exterior of the end face of the impeller shaft, and the other end of each positioning hole is closed. The shape of the tail end of each blade is identical and matched with that of a combination of the corresponding insertion groove and the corresponding positioning hole. The blades are inserted into the insertion grooves and the positioning holes. The detachable centrifugal fan impeller is simple in structure; the blades can be independently replaced, so that the equipment use and maintenance cost is reduced; and in addition, the structure can be applied to various impellers, so that the detachable centrifugal fan impeller is wide in application range and convenient to popularize.
Description
technical field:
The present invention relates to air purification field, particularly relate to a kind of removable centrifugal fan impeller.
background technique:
Its working principle of centrifugal fan be air-flow by fan shaft to entering blade space, then at the driving further aspect of impeller with vane rotary, under the effect of inertia, improve energy on the other hand, leave impeller along radial direction, the centrifugal force by generation does work.
Centrifugal fan is the conventional supplement production equipment of the more enterprise of dust production; be mainly used in ventilating with dust removal apparatus; as in stone material cutting and polishing operation, cyclone dust collector and sack cleaner etc. all need to utilize centrifugal fan to carry out dust removal process to production site; guarantee that production environment is clean, the protection producer is physically and mentally healthy.
In order to ensure gas flow, impeller is the vitals in centrifugal blower, but the impeller of existing centrifugal blower, its blade is all fixedly installed on wheel shaft, once wherein a slice blade receives damage, by balanced for the transmission destroying integral wheel, and whole impeller can only be changed, so just increase maintenance and the user cost of equipment.
summary of the invention:
Technical problem to be solved by this invention is, provides a kind of removable centrifugal fan impeller facilitating blade independently to change.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of removable centrifugal fan impeller, there is the wheel shaft of cylindrical structure, on the circumferential surface of described wheel shaft, uniform array has some being made up of metallic material and the identical blade of angle, the center of wheel shaft is provided with the axis hole that two ends communicate, described axis hole is provided with keyway, one side end face of described wheel shaft is provided with the inserting groove in " L " type structure, described inserting groove straight flange communicates with the outside of wheel shaft circumferential surface, another straight flange is communicated with the positioning hole be arranged on wheel shaft, one end of described positioning hole and inserting groove the same side communicates with the end face outside of wheel shaft, the other end is closed, the end of described blade is identical with the combined shaped of positioning hole with inserting groove and match, blade is plugged in inserting groove and positioning hole.
The length of described inserting groove and positioning hole is longer than the bottom lengths of blade.
The port position of described positioning hole is provided with internal thread, and this port is provided with the caging bolt be threaded with described internal thread.
The internal face of described inserting groove is fixedly installed for adsorbing and the magnetic flakes of stator blade.
Compared with prior art, usefulness of the present invention is: this removable centrifugal fan impeller structure is simple, and blade can be changed separately, reduce the use and maintenance cost of equipment, and this structure can be used on various impeller, using scope is wide, is convenient to promote.
accompanying drawing illustrates:
Accompanying drawing 1 is a kind of removable centrifugal fan impeller end-face structure schematic diagram of the present invention;
Fig. 2 is the schematic enlarged-scale view of A in Fig. 1.
In figure: 1, wheel shaft; 2, blade; 3, axis hole; 4, keyway; 5, inserting groove; 6, positioning hole; 7, caging bolt; 8, magnetic tablet.
embodiment:
Describe the present invention below in conjunction with the drawings and specific embodiments.
A kind of removable centrifugal fan impeller shown in Fig. 1, there is the wheel shaft 1 of cylindrical structure, on the circumferential surface of described wheel shaft 1, uniform array has some being made up of metallic material and the identical blade 2 of angle, and the center of wheel shaft 1 is provided with the axis hole 3 that two ends communicate, and described axis hole 3 is provided with keyway 4, as shown in Figure 2, one side end face of described wheel shaft 1 is provided with the inserting groove 5 in " L " type structure, described inserting groove 5 one straight flanges communicate with the outside of wheel shaft 1 circumferential surface, another straight flange is communicated with the positioning hole 6 be arranged on wheel shaft 1, one end of described positioning hole 6 and inserting groove 5 the same side communicates with the end face outside of wheel shaft 1, the other end is closed, the end of described blade 2 is identical with the combined shaped of positioning hole 6 with inserting groove 5 and match, blade 2 is plugged in inserting groove 5 and positioning hole 6, the length of described inserting groove 5 and positioning hole 6 is longer than the bottom lengths of blade 2, in order to carry out spacing to the blade 2 in inserting groove 5 and positioning hole 6, the port position of described positioning hole 6 is provided with internal thread, and this port is provided with the caging bolt 7 be threaded with described internal thread, the internal face of described inserting groove 5 is fixedly installed for adsorbing and the magnetic flakes 8 of stator blade 2.
During use, the position of the rounded structure of blade 2 bottom end face and L-type structure is plugged in inserting groove 5 on wheel shaft 1 and positioning hole 6, blade 2 adsorbs fixing by the magnetic flakes 8 of inserting groove 5 inwall, then caging bolt 7 is screwed in the port position of positioning hole 6, fix spacing further to blade, from slippage wheel shaft 1 when preventing it from operating; When changing blade 2, only need take off caging bolt 7 by screw-driver, then extract blade 2 out.
This removable centrifugal fan impeller structure is simple, and blade 2 can be changed separately, reduces the use and maintenance cost of equipment, and this structure can be used on various impeller, and using scope is wide, is convenient to promote.
