Abstract
The utility model discloses a jet-stream axial flow pump in chemical tank, which comprises a principal axis, a blade wheel, a guide vane base, a guide vane, a guide shell, a dead lever and a mounting base. The top of the principal axis is concentric with an electric machine rotor axis and is in rigid connection, which is arranged on a mounting base along with the electric machine. The bottom of the principal axis is provided with the blade wheel. The guide vane with the length along axial direction is arranged on radial circumference of the guide vane base. So, the liquid can cross the guide vane base smoothly. Moreover, the guide vane base is positioned at low end inside diameter of a draft tube through periphery of the guide vane. Top end of a draft tube is connected to a fixing bar that is connected in rigidity with the mounting base. The draft tube is concentric with the mounting base, the principal axis and the guide vane base. The utility model designs the draft tube to ensure the technology of the axial flow pump circulating mixing reaction fluid technology does not require the installation of pipeline, which is specially practically for mixing reaction fluid in small retort.
Description
Affiliated technical field
The utility model belongs to the reaction liquid mixing apparatus in the chemical reaction jar, especially for the mixed axial-flow pump of reaction liquid.
Background technique
In the chemical industry, in order to make the liquid circulation that participates in chemical reaction in the retort evenly mixed, fast reaction speed is often used axial-flow pump.General axial-flow pump is taken out the reaction liquid of retort one side to a pipeline high position in the suction mode, and reaction liquid flows to the opposite side of retort again along the other end outlet of pipeline then, and is mixed with the reaction liquid in the retort, forms circulation, accelerates chemical reaction velocity.The technology of the mixed reaction liquid of the circulation of this axial-flow pump needs pipe laying, and cost is big, and electric energy expends also many, and has difficulties such as seal for pipe joints and maintenance.The mode of its structure and installation as shown in Figure 2.
Summary of the invention
The purpose of this utility model is a kind of above-mentioned shortcoming that can overcome prior art of design, and cost is low, power consumption is little, do not need pipeline, the prompt streaming axial-flow pump of good airproof performance, long service life.
To achieve these goals, the utility model is made up of main shaft, impeller, stator seat, stator, guide shell, fixing rod and fitting seat.The upper end of main shaft is concentric with machine shaft and become rigidity to connect, and is fixed on the fitting seat with motor, and impeller is equipped with in the lower end of main shaft.The radial periphery of stator seat is equipped with stator, the length direction direct-axis of stator to, make liquid can pass the stator seat swimmingly and flow, the stator seat is fixed in the bottom diameter of guide shell by the periphery of stator.The last termination fixing rod of guide shell, fixing rod become rigidity to connect with fitting seat; Guide shell is concentric with fitting seat, main shaft and stator seat.
Because the utility model designed guide shell, so this axial-flow pump used prompt stream mode, simplified the structure and the installation workload of circular response jar greatly.

Among the figure, 1. main shaft, 2. impeller, 3. stator seat, 4. stator, 5. guide shell, 6. fixing rod, 7. fitting seat.
Embodiment
As shown in Figure 1, the utility model is made up of main shaft 1, impeller 2, stator seat 3, stator 4, guide shell 5, fixing rod 6 and fitting seat 7.The upper end of main shaft 1 is concentric with machine shaft and become rigidity to connect, and is fixed on the fitting seat 7 with motor, and impeller 2 is equipped with in the lower end of main shaft 1.The radial periphery of stator seat 3 is equipped with stator 4, the length direction direct-axis of stator 4 to, make liquid can pass stator seat 3 swimmingly and flow, stator seat 3 is fixed in the bottom diameter of guide shell 5 by the periphery of stator 4.The last termination fixing rod 6 of guide shell 5,7 one-tenth rigidity of fixing rod 6 and fitting seat connect, can be with welding.Guide shell 5 is concentric with fitting seat 7, main shaft 1 and stator seat 3.There is a flange that outwards protrudes the upper end of guide shell 5, and mounting hole is arranged on the flange, uses for motor and coupled reaction tank body are installed.On the fitting seat 7 mounting hole is arranged.The upper end of main shaft 1 connects with machine shaft, can use welding, also can use coupling, can also the two be united two into one during fabrication with the machine shaft lengthening.
The working procedure of prompt streaming axial-flow pump is as follows:
When main shaft 1 rotation, impeller 2 also rotates, and forces the reaction liquid in the guide shell 5 to flow downward, and the reaction liquid of guide shell 5 over top flows in the guide shell 5 and replenishes.When reaction liquid flow to stator 4 places, make the rotation function of liquid change into the energy of downward axial motion, liquid is impacted downwards, reach and stir guide shell 5 outer liquid, make the purpose of the interior material uniform reaction of retort.Prompt streaming axial-flow pump is to make reaction liquid with short prompt path movement, rather than as the mode of using axial-flow pump, makes flow of liquid through external pipe, adds fast response thereby reached the stirring reaction liquid, and it makes whole circulation become simple and direct.
Fitting seat 7 of the present utility model both can be used for installing motor, and its profile can be designed to the cover plate for manhole of retort again, and such design is greatly simplified the retort structure, and easy to maintenance.Because the bottom of impeller 2 has stator 4 to make the chemical reaction liquid of output eliminate rotation, has improved efficient.Use the prompt stream mode of guide shell, simplified the structure and the installation workload of retort in the chemical industry equipment greatly.
