Abstract
The utility model relates to a high-efficiency and energy-saving stirrer for sewage treatment tanks. The utility model is mainly composed of an electric motor 1, a shaft coupling 2, a power seat 3, a main shaft 4, a rolling bearing 5, a machine body 6, a water inlet pipe 7, a rolling bearing 8, mechanical seal 9, a bearing seat 10, an impeller chamber 11, an impeller 12, and a water division groove 13, wherein, the end of the main shaft 4 which is positioned in the power seat 3 is connected with an output shaft of the electric motor 1 by the shaft coupling 2, the end of the main shaft 4 which is positioned in the impeller chamber 11 is fixedly connected with the impeller 10, and a water inlet of the bearing seat 10 is provided with the water inlet pipe 7. The utility model causes water to be fully stirred, eliminates dead angles, and has the advantages of small running resistance of the impeller, high transfer efficiency of the power, low energy consumption, low cost, small volume, simple structure, and convenient maintenance.
Description
One, technical field:
The utility model relates to a kind of stirrer, especially in the sewage disposal anaerobic pond, is used to stir water layer, makes that activated sludge rises at the bottom of the pond, and is covered with the energy-efficient stirrer in pond.
Two, background technology:
Treatment tank generally adopts diving mixer and perpendicular axis type stirrer at present.Diving mixer is installed on the subjacent waters, and mixer arm promotes current to a direction level and realizes stirring water function.This machine plug-flow direction is fixed, and very easily forms the dead angle area that does not mix in the pond.The perpendicular axis type stirrer adopts the single or multiple lift level that paddle, i.e. frame paddle are installed.This machine is improved mixing greatly of dead angle area in the water, but because pond when dark, multilayer paddle or slurry frame rotational resistance in water are very big, thereby cause the adapted motor power (output) very big, so the running cost height.
Three, summary of the invention:
The purpose of this utility model provides a kind of energy-efficient stirrer.
Concrete scheme of the present utility model is: a kind of energy-efficient stirrer, and the other end of body is connected with blade wheel chamber by bearing support one of body by power seat installation motor, at the tail end of blade wheel chamber bypass channel is installed; The axial centre of power seat, body, blade wheel chamber is communicated with by main shaft, in the contact position of main shaft and power seat and main shaft and bearing support rolling bearing is installed, and main shaft is set with mechanical seal at the port that stretches into blade wheel chamber; It is characterized in that: be positioned at the output shaft of the spindle end of power seat by shaft coupling connection motor, the spindle end that is positioned at blade wheel chamber is connected with impeller; Water-in at bearing support is equipped with water inlet pipe.
The utility model compared with prior art has following advantage:
1. this machine is according to marine propeller and propeller pump principle of work, and through hydraulic model test, the plug-flow impeller running resistance of particular design is little, therefore power conversion efficient height is on average lower more than 30%, than perpendicular axis type stirrer energy consumption, working cost is low, and energy-saving benefit is remarkable.
2. this machine adopts radiation jet, and circumferentially uniform several water inlet pipe calibers and pipe range can regulated as required in a big way, and therefore the existing very wide service area of upper and lower circulation can make water fully be stirred again, has eliminated the dead angle.
3. compact construction, volume is little, and is simple in structure, easy to maintenance.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model.
Five, embodiment:
As shown in Figure 1: the utility model mainly is made up of motor 1, shaft coupling 2, power seat 3, main shaft 4, rolling bearing 5, body 6, water inlet pipe 7, rolling bearing 8, mechanical seal 9, bearing support 10, blade wheel chamber 11, impeller 12, bypass channel 13.Annexation between them is: the other end of body 6 is connected with blade wheel chamber 11 by bearing support 10 one of body 6 by power seat 3 installation motors 1, the tail end installation bypass channel 13 in blade wheel chamber 11; The axial centre of power seat 3, body 6, blade wheel chamber 11 is communicated with by main shaft 4, in the contact position of main shaft 4 and power seat 3 and main shaft 4 and bearing support 10 rolling bearing 5,8 is installed, and main shaft 4 is set with mechanical seal 9 at the port that stretches into blade wheel chamber 11; It is characterized in that: be positioned at the output shaft of main shaft 4 ends of power seat 3 by shaft coupling 2 connection motors 1, main shaft 4 ends that are positioned at blade wheel chamber 11 are connected with impeller 10; Water-in at bearing support 10 is equipped with water inlet pipe 7.
The utility model is performed such work: motor 1 drives the particular design impeller 12 middling speeds rotation that is installed on the main shaft through shaft coupling 2, main shaft 4.Water inlet pipe 7 links to each other with pipe flange on the bearing support 10, and the negative pressure that forms during impeller 12 rotations promotes water and enters blade wheel chamber 11 through water inlet pipe, after blade wheel chamber obtains energy, through 8 splitter boxs and bottom outlet to around and the bottom jet flow.Thereby with pond bottom aquifer and mud stir, on turn over.Because of the water that sucks is upper water, so form the annularly flow up and down of current.Simultaneously 8 splitter boxs are to be 360 ° of radiation jets, thus not have in the pond stirring less than the dead angle.
