Abstract
The invention relates to the field of draught fans, and discloses a draught fan partition plate. The draught fan partition plate is characterized in that welding structures exist between a left side plate and a small sealing and positioning block, between the positioning block and a right side plate, between an outer side plate and an inclined side plate, and between the inclined side plate and a large sealing and positioning block respectively, and the left side plate and the right side plate are welded together through a diversion blade. The left side plate, the outer side plate, the right side plate and the inclined side plate are all made of steel plates. Before welding is conducted, surface processing is conducted on the left side plate, the outer side plate, the right side plate and the inclined side plate. Due to the fact that the technical scheme is adopted, the production procedure is simple, and production cost is reduced.
Description
Technical field
The present invention relates to blower fan field, is a kind of blower fan dividing plate.
Background technique
At present, the dividing plate in centrifugal blower, all adopts iron casting, and during production, the blower fan of the different blower fans of different company all needs to make different wooden models and carries out foundry casting again, finally also needs to carry out annealing in process.In the process of making, also easily there is pore, slag inclusion, defects i.e.cracks in foundry goods, the comparatively coarse impact in surface is used.Novel welding-type dividing plate is formed by Plate Welding completely, and without complicated production technique process, and cost is lower.
Summary of the invention
The object of this invention is to provide a kind of blower fan dividing plate.By Plate Welding, formed, without complicated production technique process, and cost is lower.
The present invention is achieved in that a kind of blower fan dividing plate, it is characterized in that left sideboard and little sealing positioning block, positioning block and right sideboard, outer panel and tiltedly between side plate, oblique side plate and large sealing positioning block, is welded structure; Left sideboard and right sideboard are welded together by guide vane.
The material of left sideboard, outer panel, right sideboard, oblique side plate is steel plate.
Before welding, left sideboard, outer panel, right sideboard, oblique side plate carry out surface treatment.
Owing to having adopted technique scheme, production process is simple, has reduced cost of production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In the drawings: 1, left sideboard; 2, little sealing positioning block; 3, positioning block; 4, outer panel; 5, right sideboard; 6, oblique side plate; 7, seal greatly positioning block; 8, guide vane.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
In Fig. 1, between left sideboard 1 and little sealing positioning block 2, positioning block 3 and right sideboard 5, outer panel 4 and oblique side plate 6, oblique side plate 6 and large sealing positioning block 7, be welded structure; Left sideboard 1 is welded together by guide vane 8 with right sideboard 5.The material of left sideboard 1, outer panel 4, right sideboard 5, oblique side plate 6 is steel plate.
Before welding, left sideboard 1, outer panel 4, right sideboard 5, oblique side plate 6 carry out surface treatment, make dividing plate inner flow passage smooth surface, do not affect gas flow efficiency.
