Description
Technical Field
The utility model relates to an kind of stirring vane paddles especially relate to kind of low-speed impeller's stirring vane paddle.
Background
The submersible water impeller is mainly divided into two series of mixing stirring and low-speed impeller, and the low-speed impeller is mainly suitable for aeration tanks, anaerobic tanks and the like of industrial and urban sewage treatment plants, generates strong water flow with low tangential flow and can be used for water circulation in the tanks and establishing water flow in the stages of nitrification, denitrification and dephosphorization and the like.
In water treatment engineering (especially waste water treatment), the submersible water impeller is an indispensable important component-a component for stirring and mixing water flow, and the impeller blade is the most important functional component of the component.
The basic structure of the impeller is that the submersible motor reaches a set output rotating speed through the speed reducer, the impeller is assembled on an output shaft of the speed reducer, when the impeller is in a working state, the impeller rotates at a constant speed, the motion trail of two blades on the impeller forcedly divides a water body into inverted cones, so that the pressure difference between the front and the back of the water body is established, and the water body moves forward to realize the function of equipment.
Because the impeller works underwater for a long time, the impeller is required to have high reliability, low energy consumption and high efficiency. The paddle requirement in sewage treatment is quite high, the submersible water impeller is mainly used for stirring flocculation and biochemical filler in a filler pool, and the paddle speed is not high, but the diameter is larger, so that the filler in the pool cannot be damaged, and the surface needs to be coated; the existing paddle in the market is difficult to realize by only depending on glass fiber reinforced plastic materials, has poor quality stability and uneven surface, and is not suitable for the requirement of high rotating speed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects and provides stirring blades of the low-speed impeller.
In order to overcome the defect that exists among the background art, the utility model provides a technical scheme that its technical problem adopted is: the stirring blade paddle of the low-speed impeller comprises a stirring blade paddle, the stirring blade paddle is of a hollow structure, a pre-embedded flange is arranged at the connecting end part of the stirring blade paddle, which is connected with a connecting piece of the impeller, a reinforcing rib plate is connected onto the pre-embedded flange, and a filler is arranged in the hollow inner cavity of the stirring blade paddle.
According to another embodiments of the present invention, step includes that the material of the paddle is glass fiber reinforced plastic.
According to another embodiments of the present invention, step includes that the reinforcing rib plate is provided with two or four steps.
According to another embodiments of the present invention, step includes that the filler is a waterproof material
The beneficial effects of the utility model are that this kind of stirring paddle of low-speed impeller increases the intensity of paddle root, make it can bear the weight of the reaction force that the paddle promoted the water and produced, and fill in the hollow inner chamber of paddle and keep away the water material, solve the paddle because of the preparation weight not meet with the inner chamber catchment how much not the unbalanced problem that causes, increase life, and fill behind the foaming material that keeps away water, the overall density of paddle reduces and is less than the water density, make the paddle in time transfer into the pond, float on the surface of water, convenient clearance and maintenance.
Drawings
The present invention will be further described in with reference to the following drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
wherein: 1. the device comprises glass fiber reinforced plastic, 2, reinforcing rib plates, 3, fillers, 4, pre-embedded flanges, 5 and stirring blades.
Detailed Description
The stirring blade of the low-speed impeller consists of components such as glass fiber reinforced plastics 1, reinforcing rib plates 2, fillers 3, embedded flanges 4 and stirring blades 5, and the specific structure comprises:
stirring paddle 5 is hollow structure, and the tip of being connected with impeller connecting piece is equipped with pre-buried flange 4 in stirring paddle 5, connects deep floor 2 on pre-buried flange 4, be equipped with filler 3 in the hollow inner chamber of stirring paddle 5. The glass fiber reinforced plastic blade paddle is a stirring blade paddle used by the submersible low-speed impeller, is difficult to realize simply depending on the cost saving of glass fiber reinforced plastic materials because of the requirement of bearing larger torsion, and two or four rib plates are added at the position of the embedded flange to increase the strength of the root part of the blade, so that the blade paddle can bear the reaction force generated by the blade to push a water body.
The stirring paddle 5 is made of glass fiber reinforced plastic 1. the glass fiber reinforced plastic is fiber reinforced plastic, refers to a matrix of unsaturated polyester, epoxy resin and phenolic resin reinforced by glass fiber, and has the greatest characteristics of corrosion resistance, acid and alkali resistance, and belongs to the anticorrosion stirring paddle.
The reinforcing rib plate 2 is provided with two or four channels. The reinforcing rib plate 2 increases the strength of the root part of the blade, so that the blade can bear the reaction force generated by the blade pushing the water body.
The filler 3 is a water-avoiding material, the water-avoiding material is filled in the hollow inner cavity of the blade, the problem of unbalance caused by the fact that the weight of the blade is not and the water collection amount of the inner cavity is not is solved, the service life is prolonged, and after the water-avoiding foaming material is filled, the integral density of the blade is reduced to be smaller than the water density, so that the blade floats on the water surface even if being transferred into a water pool, and the cleaning and the maintenance are convenient.
Claims (4)
