A kind of paddle for the preneutralization reactive tank
Technical field
The utility model relates to a kind of mixing plant, particularly relates to a kind of paddle for the preneutralization reactive tank.
Background technology
The preneutralization reactive tank is the important leverage that realizes product quality as the visual plant in the phosphoric acid ammonium phosphate production process, and it is especially important that mixing plant wherein then seems.The preneutralization groove has that diameter is little, highly high, and the bottom is not suitable for installing the characteristics of support, and is therefore higher to the designing requirement of axle.For solving above-mentioned technical barrier, normally adopt large diameter materials in the tube to make major axis, but because the diameter of agitator is less, large diameter materials in the tube certainly will take the space of stirring vane, thereby affect mixing effect.Because whole axle is longer, need use large crane during dismounting simultaneously, very inconvenient maintenance, and also expense cost is very high.
The utility model content
For addressing the above problem, the utility model provides a kind of paddle for the preneutralization reactive tank, so that mixing plant maintenance in the preneutralization reactive tank, convenient disassembly make mixing effect reach optimization simultaneously.
The purpose of this utility model is achieved by following technical solution.
A kind of paddle for the preneutralization reactive tank, mainly formed by motor, gear reduction unit, frame and shaft, the input of described gear reduction unit links to each other with the output of motor, the output of gear reduction unit links to each other with shaft by shaft coupling, the base of described frame upper end and reductor, the lower end is fixed on installs on the bottom, and described shaft is comprised of upper semiaxis and lower semiaxis, and is respectively equipped with upper strata agitator and lower floor's agitator at lower semiaxis.
Above-mentioned a kind of paddle for the preneutralization reactive tank, semiaxis connects by the rigid attachment device with lower semiaxis on it.
Above-mentioned a kind of paddle for the preneutralization reactive tank, its upper strata agitator and lower floor's agitator are three leaf variable cross section stirrers.
The beneficial effects of the utility model are:
Compared with prior art, the utility model has reached the optimization of mixing effect by upper and lower two-layer agitator is set, and makes the real realization industrialization of mixing plant.Because being divided into two joints, whole shaft adopt positive coupling to connect, so that the maintenance easy accessibility reduces use cost greatly.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Flow direction of material figure when Fig. 2 is the utility model work.
Among the figure: the 1-motor, the 2-gear reduction unit, the 3-shaft coupling, the 4-frame, 5-installs bottom, the upper semiaxis of 6-, 7-positive coupling, 8-upper strata agitator, semiaxis under the 9-, 10-lower floor agitator.
The specific embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.
As shown in Figure 1, a kind of paddle for the preneutralization reactive tank, mainly formed by motor 1, gear reduction unit 2, frame 4 and shaft, the input of described gear reduction unit 2 links to each other with the output of motor 1, the output of gear reduction unit 2 links to each other with shaft by shaft coupling 3, described frame 4 upper ends are connected with the base of gear reduction unit 2, the lower end is fixed on installs on the bottom 5, described shaft is comprised of upper semiaxis 6 and lower semiaxis 9, and is respectively equipped with upper strata agitator 8 and lower floor's agitator 10 at lower semiaxis 2.
Above-mentioned a kind of paddle for the preneutralization reactive tank, semiaxis 6 connects by rigid attachment device 7 with lower semiaxis 9 on it.
Above-mentioned a kind of paddle for the preneutralization reactive tank, its upper strata agitator 8 and lower floor's agitator 10 are three leaf variable cross section stirrers.
Further describe operation principle of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 2, according to the requirement of production technology, material will contact in groove again, realizes neutralization reaction.So the utility model is provided with upper strata agitator 8 and lower floor's agitator 10, lower floor's agitator 10 near bottom land is 36% of groove footpath, blade is wide blade profile, stream shape is mainly axial-flow type, it has powerful lifting rate, makes the bottom material rush at bottom land with stronger speed, moves upward with the bounce-back of stronger energy after running into the stopping of bottom again, blade is the variable-section variable angle type, and it is in the situation of identical lifting rate energy-conservation 30%; Upper strata agitator 8 can also produce hoop stream when producing axial flow, by suitable agitator interlamellar spacing, after the lower floor's agitator 10 promotion materials that are in the bottom rise to certain height, upper strata agitator 8 forms presses down material and the rising material is collided, will be to scattering all around, material can form a mixed zone, realization response fully.And the contact density that the mixed flow that forms also increases material is stirred on the upper strata, and when upper strata agitator 8 pushed intermediate material downwards again, the material of periphery replenished timely, thereby material exchanges in the whole tank that forms.
