Abstract

The utility model relates to a stirring paddle used for a high solid content tank; the stirring paddle can effectively solve the problem of enhancing axial flow and radial flow, thereby preventing solid from quickly depositing; the technical proposal is as follows: the stirring paddle comprises a stirring shaft, and an upper layered paddle and a bottom layered paddle which are arranged on the shaft; the upper layered paddle consists of three axial-flow blades which are symmetrically distributed; an inflow side of each axial-flow blade is at the lower part, and an overflow side is on the upper part; the bottom layered paddle consists of a frame type paddle which is welded at the lower part of the stirring shaft; the stirring shaft is provided with a lug; the angle of the lug rotates towards the stress direction is 5 degrees to 10 degrees; the upper layered paddle is arranged on the lug. The stirring paddle has good stirring effect, saves power consumption, can be widely applied in solid and liquid stirring tanks with square conical bottom or circular conical bottom in metallurgy, chemical, coal and other fields, and has good economic and social benefit.

Description

A kind of high groove paddle that contains admittedly

One, technical field

The utility model relates to agitating device, particularly a kind of high groove paddle that contains admittedly.

Two, background technology

At the bottom of the square awl of industries such as metallurgy, chemical industry, coal or the agitating device that uses of circular awl end solid-liquid tank diameter, general upper strata blade adopts oblique leaf oar formula, forms axially shunting, radially shunting and hoop shunting.Lower floor's blade generally adopts the disc turbine formula, forms radial flow.Reach and mix, it is little to contain difference up and down admittedly, and prevents the purpose difficulty relatively of the fast deposition of solid, and effect is also undesirable.Because generally speaking, the material solid-liquid density difference of this tank diameter is bigger, and solid content is big, so must have strong axial flow and radial flow could promote the even mixing of whole trough material, the reform of paddle is imperative.

Three, utility model content

At above-mentioned situation, for overcoming the defective of prior art, the purpose of this utility model just provides a kind of high groove paddle that contains admittedly, can effectively solve and strengthen axial flow and radial flow, thereby prevent the problem of the fast deposition of solid, the technical scheme of its solution is, comprise shaft and upper strata oar and bottom oar on it, said upper strata oar is made up of the axial-flow type blade of three symmetrical distributions, and meeting of axial-flow type blade flowed the limit following, and the overflow limit upwards, the bottom oar is welded by the frame oar and constitutes in the bottom of shaft, journal stirrup is housed on the shaft, and the journal stirrup angle is to being subjected to the force direction rotation to be 5 °～10 °, and the upper strata oar is contained on the journal stirrup.The utility model mixing effect is good, saves power consumption, can be widely used at the bottom of the square awl of industries such as metallurgy, chemical industry, coal or circular awl end solid-liquid tank diameter, has good economic and social benefit.

Four, description of drawings

Fig. 1 is the structural front view of the utility model in tank diameter at the bottom of the square awl.

Fig. 2 is the vertical view of the utility model in tank diameter at the bottom of the square awl.

Five, the specific embodiment

Below in conjunction with accompanying drawing concrete enforcement of the present utility model is studied detailed explanation.

Provide by Fig. 1-2, the utility model comprises shaft and upper strata oar and bottom oar on it, said upper strata oar 3 is made up of the axial-flow type blade of three symmetrical distributions, meeting of axial-flow type blade flowed limit 6 following, overflow limit 7 makes progress, and the bottom oar is welded by frame oar 5 and constitutes in the bottom of shaft 1, and journal stirrup 4 is housed on the shaft, the journal stirrup angle is to being subjected to the force direction rotation to be 5 °～10 °, and upper strata oar 3 is contained on the journal stirrup 4.

In order to guarantee result of use, said journal stirrup 4 is welded on shaft 1, and upper strata oar 3 is contained on the journal stirrup 4 by bolt and nut 2; Upper strata oar 3 has one deck or the multilayer more than 2 layers or 3 layers at least, provides 2 layers among Fig. 1.According to the requirement of different material and mixing effect, the angle of inclination of each layer oar in these upper strata oars may be all different.

It is wide at the top and narrow at the bottom trapezoidal that said frame oar 5 is.

Working condition of the present utility model is, the utility model is vertically placed tank diameter 8 centers, and the frame oar 5 of bottom places the awl end under the tank diameter, because upper strata of the present utility model oar 3 adopts the axial-flow type blade, but mounting means is opposite with general press-down type, adopts the formula that raises up.The stream limit of meeting that is about to blade is installed in the bottom, and the overflow limit makes progress, and when agitating device turned round, fluid was not to be depressed into bottom land, bounce-back then, but kicked up the integral body circulation of the whole groove inner fluid of formation that falls then.

Simultaneously, the journal stirrup angle that blade is installed will to reduce resistance, reduce flow loss to being subjected to 5 °～10 ° of force direction rotations, makes fluid more smooth and easy in the flow field of cone tank body portion, reaches the purpose of saving power consumption, improving mixing effect.The turbine oar is replaced by the frame blade, more helps improving mixing effect.

The utility model advantageous effect is as follows:

Upper-layer paddle adopts the high-efficiency axial flow paddle not only to realize strong axial flow, and the peace of blade uniqueness The dress mode makes the flow field more smoothly, has also played certain shear action for the material of bulk, is changing Reduced the power consumption that stirs in the time of kind mixing effect. Bottom paddle adopts the frame blade, and it can be scraped fully Wall is used the shearing force that material level puts and is obviously strengthened, and more is conducive to material and keeps well flowing in position, cone bottom Property prevents from scabbing or stops up the discharging mouth of pipe, has good economic and social benefit.
