Abstract
The utility model discloses a wearable impeller for a fan, which comprises a hub disk and a plurality of blades welded together with the hub disk, wherein a ceramic element is adhered on the front end of each blade, and a wearable material layer is laid on windward sides of the blades and the hub disk. According to the wearable impeller for the fan disclosed by the utility model, the wear-resisting property of the impeller is greatly improved by adopting the structure of laying the wearable material layer on the windward sides of the blades and the hub disk, the dropping of the wearable material layer is avoided and the service life of the impeller is prolonged.
Description
Technical field
The utility model relates to a kind of draught fan impeller, particularly a kind of blower fan abrasion proof impeller.
Background technique
Electric power, steel and cement manufacturing enterprise produce continuously, are used for system dust removing. and process cycles blower fan and roll squeezer cement grinding mill Joint Production systemic circulation blower fan, the problem of resistance to wearing of impeller is an important topic.
Circulating fan is because each enterprise's operating mode is different, and it is different that the raw material of use, temperature, dust concentration, airduct move towards, and formed abrading section, degree are also inequality.Even same enterprise, identical device, the production line of same materials identical set, the damage in impeller situation is also inequality.Common impeller is used for maximum 3 months of working life of cement grinding mill systemic circulation blower fan, 1 few wheat harvesting period, and just needing stops production repairs.The main abrading section of systemic circulation blower fan is at the connecting part and the blade front end of blower fan hub disk and root of blade.When the connecting part of root of blade and hub disk may wear to a certain degree, blade will cause equipment accident with the back disk detachment.Frequent change impeller one is that increase cost of production two is to influence equipment to move continuously, and productivity descends.
The method that improves the impeller abrasion-proof performance is more, and pasting ceramic plate at the damage in impeller position is reasonable method.When the conventional ceramic impeller was made, blade and hub disk adopted welding to form weld seam, the bonding in welded joints not labor of ceramics; Under high speed dust-containing airflow impact wear situation, ceramics is prone to come off, and ceramics, porcelain spare arrangement mode are prone to make the jointing mill to leak; Ceramics comes off, cause unbalance, vibration influence working life.
Summary of the invention
The utility model provides a kind of blower fan abrasion proof impeller for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of blower fan abrasion proof impeller; Comprise hub disk and with a plurality of blades of its welding; Said blade front end is bonded with ceramic fitting, on the windward side of said blade and said hub disk, completely is covered with wear-resistant material layer.
Said blade is inserted in the said hub disk, and is connected through plug weld with it.
Said wear-resistant material layer is to be formed by a plurality of ceramic plates that are bonded on the said blade.
Said wear-resistant material layer is to be formed by the titanium alloy that the shop is welded on the said blade.
A plurality of said ceramic plate fissure of displacement are arranged.
Be provided with the adaptive step of wear-resistant material layer that forms with said titanium alloy in the said ceramic fitting.
A plurality of said ceramic fittings are provided with the rim of the mouth at the place of interconnecting, adjacent said ceramic fitting connects through said rim of the mouth.
Advantage and the good effect that the utlity model has are:
1) through completely being covered with the structure of wear-resistant material layer on the windward side that is employed in blade and hub disk, greatly improved the wear-resisting property of impeller.
2) through adopting blade to insert the structure of plug welding behind the hub disk; In the connecting part of root of blade and hub disk, the position easy to wear of blower fan does not just exist weld seam, the bonding blade surface of being close to of ceramic plate; Dust-containing airflow can't be ground off binder, avoided ceramics to come off.
3) adopt ceramic plate to form wear-resistant material layer, ceramic hardness HRA is greater than more than 84, and wear-resisting property is fabulous, is hundred times of Ordinary Steels.
4) adopt titanium alloy to form wear-resistant material layer, combine, further improved the wear-resisting property of impeller, be highly suitable for granule content greater than 150mg/m with the ceramic fitting of blade front end
3More than and contain the bigger operating mode of particle.And solved welding deformation, the problem of stress relief.
5) a plurality of ceramic plates that form wear-resistant material layer adopt fissure of displacement structure arranged, make the dust-laden particle wash away ceramics along seam crossing, have improved the working life of impeller.
6) blade front end area is less, and the shop solder alloy can not solve the high speed dust-containing airflow and washes away, in ceramic fitting with the level, solved the problem that the shop solder alloy combines with ceramic fitting, further improved the wear-resisting property of impeller.
7) the blade front end adopts the ceramic fitting of belt mouth, forms slitless connection, the working life of further having improved impeller.
