Abstract

The utility model discloses a grooving structure used for an impeller, and relates to the field of machinery. The grooving structure used for the impeller comprises vanes and a rear wheel disc, wherein each vane is provided with a plurality of bayonets, grooves corresponding to the vane bayonets are formed in the rear wheel disc, and a plurality of welding points are arranged on the vanes and the rear wheel disc. The mode that the vanes with the bayonets and the rear wheel disc with the grooves are connected in a bayonet type mode and then welded integrally is adopted, the strength of a two-layer protective structure is larger than that of a structure of a traditional impeller, the impeller obtains double protection under large rotating force, unsoldering of the vanes and alighting of the impeller are effectively avoided, running stability of the impeller is improved, and service life of the impeller is prolonged.

Description

A kind of impeller notching construction

Technical field

The utility model relates to mechanical field, particularly relate to a kind of impeller notching construction.

Background technique

Along with the utilization of blower fan in mechanical industry, people have also gradually realized significance and the Security of blower fan in entire equipment, the iron and steel stove blower fan of some large-scale iron and steel or glass industry is because air quantity, blast requires all very high, when directly welding, the blade of the large-scale impeller of tradition and rear trochal disc cause root of blade and rear trochal disc to break away from owing to rotary centrifugal force is excessive, the serious blade that makes is played the appearance of unfavorable conditions such as flying, so the welded structure form can not satisfy the requirement of strength of this impeller between each traditional part.

Therefore, design at above-mentioned situation and to make impeller under high rotating force, obtain duplicate protection, solve the blade sealing-off smoothly, a kind of impeller of the problem that impeller flies notching construction, inventor's problem to be solved just.

The model utility content

The technical problem that the utility model mainly solves provides a kind of impeller notching construction, can solve the blade sealing-off, and the problem that impeller flies makes impeller obtain duplicate protection under high rotating force.

For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of impeller notching construction is provided, comprise blade and rear trochal disc, described blade is provided with some bayonet sockets, described rear trochal disc is provided with the fluting of corresponding blade bayonet socket, is provided with some soldering points on described blade and the rear trochal disc.

The beneficial effects of the utility model are: adopt the integral solder form after the rear trochal disc bayonet coupling of the utility model by blade with bayonet and band fluting; two-layer like this protection strength structure is than big many of the structural strength of conventional impellers; make impeller under high rotating force, obtain duplicate protection, effectively avoided blade sealing-off, impeller to fly.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 be shown in the structural representation of blade;

Fig. 3 be shown in the structural representation of rear trochal disc;

The mark of each parts is as follows in the accompanying drawing: 1, blade 2, rear trochal disc 3, soldering point 4, bayonet socket 5, fluting.

Embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.

See also Fig. 1 to Fig. 3, the utility model is embodiment comprise: blade 1 and rear trochal disc 2, and described blade 1 is provided with some bayonet sockets 4, and described rear trochal disc 2 is provided with the fluting 5 of corresponding blade 1 bayonet socket 4, is provided with some soldering points 3 on described blade 1 and the rear trochal disc 2.

As shown in Figure 1, described blade 1 is fixedlyed connected with fluting 5 by bayonet socket 4 with rear trochal disc 2, passes through soldering point 3 integral solder between each part of impeller.Make that like this bulk strength of impeller is strengthened, also improved the operation stability of impeller, prolong its working life.

The utility model adopts the integral solder form by after the blade 1 of being with bayonet socket 4 and rear trochal disc 2 bayonet couplings of being with fluting 5; two-layer like this protection strength structure is than big many of the structural strength of conventional impellers; make impeller under high rotating force, obtain duplicate protection, effectively avoided blade 1 sealing-off, impeller to fly.

The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.

Claims

1. an impeller notching construction is characterized in that, comprising: blade and rear trochal disc, and described blade is provided with some bayonet sockets, and described rear trochal disc is provided with the fluting of corresponding blade bayonet socket, is provided with some soldering points on described blade and the rear trochal disc.
