Abstract
The invention discloses an impeller for crushing materials, which comprises a fixed plate and blades, wherein the fixed plate comprises an upper fixed plate and a lower fixed plate which are arranged in parallel and are in a circular ring shape, at least two blades are arranged between the upper fixed plate and the lower fixed plate and are uniformly distributed, rectangular grooves for limiting the fixed plate are arranged on the upper fixed plate and the lower fixed plate, the upper fixed plate and the lower fixed plate are fixedly connected through at least two cylindrical supporting pieces, and a feeding port is arranged at the circle center position of the upper fixed plate; the invention has the characteristic of detachable replacement by changing the fixed connection structure between the fixed plate and the blade, and simultaneously adopts wear-resistant materials, thereby having high wear resistance, repeated utilization and low maintenance cost.
Description
The technical field is as follows:
the invention relates to a centrifugal fan accessory, in particular to an impeller for crushing materials.
Background art:
the centrifugal fan impeller is a wind wheel which can axially intake air and radially output air, and utilizes centrifugal force (depending on rotating speed and outer diameter) to apply work to improve pressure of air. Similarly, the working principle can be used for designing a pulverizer with a similar structure to pulverize various materials. At present, the types of crushers for throwing materials by utilizing impellers are many, but the problem of rapid abrasion always exists and cannot be effectively solved.
The invention content is as follows:
the technical problem to be solved by the invention is as follows: overcome prior art's not enough, through the fixed connection structure who changes between fixed plate and the blade, make it have the characteristics that can dismantle the change, adopt wear-resisting material simultaneously, have the impeller that is used for smashing the material that the abrasion resistance is high.
The technical scheme of the invention is as follows: the utility model provides an impeller for smashing material, includes fixed plate and blade, characterized by: the fixed plate is two mutual parallel arrangement and is the annular upper fixed plate of circle and bottom plate, the blade is at least two, and evenly distributed sets up between upper fixed plate and the bottom plate, it is right to be provided with on upper fixed plate and the bottom plate the fixed plate carries out spacing rectangular channel, just carry out fixed connection through two at least cylinder type support piece that set up between upper fixed plate and the bottom plate, and upper fixed plate centre of a circle position is provided with the pan feeding mouth.
Further, all be provided with the steel hoop circular arc groove on upper fixed plate and the bottom plate, and be fixed with the steel hoop through the briquetting in the steel hoop circular arc groove, the steel hoop uses with the spacing opening cooperation on the fixed plate.
Furthermore, the fixed plate is a wear-resistant plate provided with a wear-resistant surface, the wear-resistant surface is arranged on the side of the blade, wear-resistant ceramic parts are adhered to the two surfaces of the blade, and the outer surface of the cylindrical support part is subjected to wear-resistant treatment.
Furthermore, a connecting flange is welded at the feed inlet.
The invention has the beneficial effects that:
1. the invention has the characteristic of detachable replacement by changing the fixed connection structure between the fixed plate and the blade, and simultaneously adopts wear-resistant materials, thereby having high wear resistance, repeated utilization and low maintenance cost.
2. The blade is arranged in the rectangular groove on the fixed plate, and the rectangular groove is communicated with the steel hoop arc groove on the fixed plate, so that the steel hoop can conveniently invade the rectangular groove and is matched with the limiting notch on the blade for use, and the blade is fixed.
3. The steel hoop is connected with the circular ring surface through the pressing block, so that the steel hoop is fixed, the position of the blade is further limited, and the blade is convenient to disassemble, assemble and replace.
4. The inner side of the fixing plate is a wear-resistant surface, the two surfaces of each blade are adhered with wear-resistant ceramic parts, and the outer surface of the cylindrical support part is subjected to wear-resistant treatment, so that the wear resistance is improved.
Description of the drawings:
fig. 1 is a front view of an impeller for pulverizing material.
Fig. 2 is a top view of an impeller for pulverizing material.
Fig. 3 is a front view of the blade.
Fig. 4 is a top view of the blade.
The specific implementation mode is as follows:
example (b): referring to fig. 1, 2, 3 and 4, in the drawings, 1-an upper circular wear-resisting plate, 2-a lower circular wear-resisting plate, 3-a blade, 4-a connecting flange, 5-a cylindrical supporting piece, 6-a pressing block, 7-a steel hoop and 8-a limiting gap.
A impeller for smashing material, including two upper and lower ring form antifriction plate and a plurality of blade of equalling divide equally, it has pan feeding mouth flange to go up the welding of ring antifriction plate centre of a circle position, there are a plurality of cylinder types to support the connecting piece between two ring form antifriction plate, the blade is fixed in the rectangular channel on the ring through two steel hoops, the steel hoop passes through the briquetting and is connected with the torus, every two-sided wear-resisting ceramic member that has all been stained with of blade, this application is rational in infrastructure, and the abrasion resistance is high, can reuse, and cost of maintenance is low.
The present application will be described in detail below with reference to the drawings and examples.
The upper annular wear-resisting plate 1 and the lower annular wear-resisting plate 2 are arranged in parallel and connected (fixed through bolts) through at least two cylindrical supporting pieces 5, the blade 3 is arranged in a rectangular groove which is formed in the upper annular wear-resisting plate 1 and the lower annular wear-resisting plate 2 and used for limiting the upper annular wear-resisting plate and the lower annular wear-resisting plate, the blade 3 is fixed in the rectangular groove in the annular ring through an upper steel hoop 7 and a lower steel hoop 7, and the steel hoops 7 are placed in steel hoop arc grooves and connected with the annular surface through pressing blocks 6; the lower part of the upper part of the blade 3 is provided with a limit gap 8.
Wear-resisting face of two ring form antifriction plate (1 and 2) is inboard at impeller 3, goes up 1 centre of a circle position welding of ring antifriction plate and has pan feeding mouth flange 4, has a plurality of cylinder type support piece 5 to connect between two ring form antifriction plate (1 and 2). The outer surface of the cylindrical support piece 5 is a wear-resistant part, the two sides of each blade 3 are respectively adhered with a wear-resistant ceramic piece, the forward and reverse rotation of the impeller can be realized, the impeller structure is in combined connection, the disassembly is convenient, the wear-resistant degree is high, the repeated use can be realized, and the maintenance cost is low.
During the use, this application is the same with current impeller user mode, and this application can remove the spacing to blade 3 through dismantling briquetting 6 and steel hoop 7, and blade 3 is taken out from the rectangular channel of two ring form antifriction plate (1 and 2) to install, dismantle and change.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent variations and modifications made to the above embodiment according to the technical spirit of the present invention still fall within the scope of the technical solution of the present invention.
