Abstract
The invention relates to an agitating impeller for a high solid content groove, which comprises an agitating shaft, and an upper layer of impellers and a lower layer of impellers, which are fixed on the agitating shaft, wherein the upper layer of impellers comprises at least three axial-flow type impellers which are symmetrically distributed, the incident flow edges of the axial-flow type impellers are arranged at the lower parts, the overflow edges of the axial-flow type impellers are arranged at the upper parts, and the lower layer of impellers are fixed at the lower part of the agitating shaft. The upper layer of impellers adopts the efficient axial-flow type impellers, not only is strong axial flow realized, but also a flow field is smoother through the unique installation mode of the impellers, a certain shearing function is also exerted on massive materials, the agitating effect is improved, and the agitating power consumption is reduced. The lower layer of impellers adopts frame-type impellers which can sufficiently scrape walls, so the shear force at a discharge position is obviously increased, materials can be better maintained with good flowability at a conical bottom part, a discharge pipe orifice is prevented from scabbing or being blocked, and good economic and social benefits are obtained.
Description
Technical field
The present invention relates to a kind of agitating device, be specifically related to a kind of high groove that contains admittedly and use paddle.
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.
Summary of the invention
For overcoming the defective of prior art, the present invention provides a kind of can effectively the solution to strengthen axial flow and radial flow, uses paddle thereby the height that prevents the fast deposition of solid contains groove admittedly.
The technical scheme that the present invention adopts is: a kind of high groove that contains is admittedly used paddle; Comprise shaft and be fixed on upper strata oar and the bottom oar on the shaft; Described said upper strata oar is made up of the axial-flow type blade of three symmetrical distributions at least; Meeting of said axial-flow type blade flowed the limit following, and the overflow limit makes progress, and described bottom oar is fixed on the bottom of shaft.
The above-mentioned a kind of high groove that contains is admittedly used paddle, and described bottom oar is welded by the frame oar and constitutes in the shaft bottom.
The above-mentioned a kind of high groove that contains is admittedly used paddle, and it is wide at the top and narrow at the bottom trapezoidal that described frame oar is.
The above-mentioned a kind of high groove that contains is admittedly used paddle, on the described shaft journal stirrup is housed, and the journal stirrup angle is to receiving the force direction rotation to be 5 °～10 °, and the upper strata oar is contained on the journal stirrup.
The above-mentioned a kind of high groove that contains is admittedly used paddle, and described upper strata oar is fixed on the journal stirrup by bolt and nut.
The above-mentioned a kind of high groove that contains is admittedly used paddle, and described upper strata oar has at least two-layer.
Advantageous effect of the present invention is following:
The upper strata oar adopts the high-efficiency axial flow paddle not only to realize strong axial flow; And the unique mounting means of blade; Make the flow field more smoothly, also played certain shear action, when improving mixing effect, reduced the power consumption that stirs for the material of bulk.The bottom oar adopts the frame blade, and it can scrape wall fully, uses the shearing force that material level puts and obviously strengthens, and more helps material and keeps well mobile in position, awl bottom, prevents to scab or stops up the discharging mouth of pipe, has good economic and social benefit.Mixing effect of the present invention is good, practices thrift power consumption, can be at the bottom of the square awl of industries such as metallurgy, chemical industry, coal or the circular end solid-liquid tank diameter of boring, have good economic and social benefit.
Description of drawings
Fig. 1 is the structural representation of the present invention in tank diameter at the bottom of the square awl.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Fig. 3 is the vertical view of the present invention in tank diameter at the bottom of the square awl.
Among the figure, 1, shaft, 2, bolt and nut, 3, the upper strata oar, 4, journal stirrup, 5, the frame oar, 6, meet the stream limit, 7, the overflow limit, 8, tank diameter at the bottom of the square awl.
The specific embodiment
Below in conjunction with accompanying drawing practical implementation of the present invention is studied detailed explanation.
Provide the embodiment that the present invention uses by Fig. 1-2 in tank diameter 8 at the bottom of the square awl, the present invention includes shaft 1 and upper strata oar on it 3 and bottom oar, 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 1; Journal stirrup 4 angles are to receiving 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, the also available in case of necessity connected mode that adopts other according to the actual requirements; Upper strata oar 3 has one deck 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 3 maybe 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 invention is, the present invention 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 invention oar 3 adopts the axial-flow type blades, but mounting means is opposite with general press-down type, the employing formula that raises up.The stream limit 6 of meeting that is about to blade is installed in the bottom, and overflow limit 7 makes progress, and when agitating device turned round, fluid was not to be depressed into bottom land, bounce-back then, but kicked up the whole circular of the whole groove inner fluid of formation that falls then.
Simultaneously, journal stirrup 4 angles that blade is installed will to reduce resistance, reduce flow loss to receiving 5 °～10 ° of force direction rotations, make fluid more smooth and easy in the flow field of cone tank body portion, reach the purpose of practicing thrift power consumption, improving mixing effect.The turbine oar is replaced by the frame blade, more helps improving mixing effect.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
