Abstract
The utility model relates to a propeller, particularly to a propeller of a decomposition trough stirring device in large-scale stirring devices in the seed decomposition process in the alumina industry. The utility model is the propeller of a decomposition trough stirring device, which comprises an upper layer paddle and a bottom layer paddle. The dimensions of the length, the width and the thickness of the bottom layer paddle are larger than those of the upper layer paddle. The length of the lower part of the blade of an outer bottom layer paddle is bigger than that of the upper part of the blade. The utility model can effectively reduce and overcome material deposit scabs at the bottom of the trough and in the dead corner and enhance the mixing effect of feed liquid. The utility model can assure that the difference of the solid inclusion rates at the top of the feed liquid and at the bottom of the feed liquid is within 5%.
Description
Technical field
The utility model relates to a kind of blade, relates in particular to a kind of blade of the large-scale whipping device decomposer whipping appts in aluminum oxide seed decomposition course, be used for reducing and overcoming the bottom land buildup scabbing, and satisfied requirement to the high mixture homogeneity of feed liquid.
Background technology
Decomposer is the special mixing plant that seed decomposes the workshop, and material liquid component is crystalline aluminum hydroxide and sodium aluminate solution liquid mixture in the groove, and feed liquid density and contain all higherly admittedly causes the bottom land buildup easily and scabs.Decomposer requires in working order the time crystalline aluminum hydroxide evenly to suspend in sodium aluminate solution, and the difference that the levels feed liquid contains admittedly is in 5%.Have decomposer whipping appts structure now as shown in Figure 1, each layer diameter of propeller blade is identical.During the stirring rake rotary work, upper strata oar 7 is responsible for feed liquid and is mixed, and 8 responsible simultaneously feed liquids of bottom oar mix the removing with the bottom land buildup.Oar 2 satisfies under the requirement of stirring intensity outside oar 1 and the upper strata in the upper strata, the outer oar 4 of oar 3 and bottom but can not satisfy the stirring requirement in the bottom, because should being responsible for feed liquid, the bottom oar mixes, also to remove the buildup at bottom land place, therefore the scouring force of bottom oar generation is just obviously not enough, the raising force that produces after baffle plate 5 changes the flow direction also can be very weak, causes the bottom land bottom to form buildup, and particularly the dead angle formation at a distance of equidistant blade scabs 6 in the corner.
The utility model content
The utility model is exactly in order to solve the problems of the technologies described above, and a kind of blade of decomposer whipping appts is provided, and purpose is to strengthen the feed liquid stirring intensity of decomposer bottom, eliminates buildup and scabs.
In order to solve the problems of the technologies described above, the utility model is achieved in that a kind of blade of decomposer whipping appts, and it comprises upper strata oar, bottom oar, and wherein the size of bottom oar is greater than the size of upper strata oar.
Described bottom oar is made of oar in outer oar of bottom and the bottom, and the upper strata oar is made of oar in oar outside the upper strata and the upper strata, and the size of oar is greater than the size of oar correspondence in oar outside the upper strata and the upper strata in outer oar of bottom and the bottom.
The blade lower length of the outer oar of described bottom is longer than blade upper length.
Described length and width, the thickness of being of a size of.
The utility model has the advantages of as follows:
Upper strata of the present utility model oar diameter remains unchanged, oar and outer oar size all strengthened at aspects such as length and width, thickness in the bottom oar was compared with the upper strata oar, at the insufficient problem of dead angle stirring intensity, the blade length of the outer oar bottom of bottom is than the outer oar upper leaf of bottom length of a film.After improving like this, the stirring intensity of bottom oar increases greatly, particularly behind the outer oar lower blade lengthening of bottom, producing downward feed liquid scouring force increases greatly, more crystalline aluminum hydroxide particle is stirred, change flowing to the strength that rises the back through baffle plate also increases greatly, reduces and has overcome the buildup of bottom land and dead angle locating effectively and scab, and improved the feed liquid mixed effect.Can guarantee that difference that feed liquid top layer and bottom contain admittedly is in 5%.

Fig. 2 is the utility model decomposer stirring rake structure and feed liquid streamline synoptic diagram.
Oar among the figure 1, in the upper strata; 2, oar outside the upper strata; 3, oar in the bottom; 4, the outer oar of bottom; 5, baffle plate; 6, scab; 7, upper strata oar; 8, bottom oar.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
A kind of blade of decomposer whipping appts comprises upper strata oar 7, bottom oar 8, and the length and width of bottom oar 8, thickness equidimension are all greater than the size of upper strata oar 7.
The blade lower length of the outer oar 4 of bottom is longer than blade upper length.
Below principle of work of the present utility model is described.
In the upper strata outside oar 1 and the upper strata oar 2 diameters remain unchanged, outer oar 4 sizes of oar 3 and bottom are all strengthening aspect length and width, the thickness in the bottom, the blade lower length of the outer oar 4 of bottom is longer than blade upper length.After improving like this, the stirring intensity of bottom oar increases greatly, particularly behind the lengthening of the outer oar blade bottom of bottom, producing downward feed liquid scouring force increases greatly, more crystalline aluminum hydroxide particle is stirred, change through baffle plate 5 and to flow to the raising force that the back produces and also increase greatly, reduce and overcome the buildup of bottom land and dead angle locating effectively and scab 6, and improved the feed liquid mixed effect.
Claims (4)
1, a kind of blade of decomposer whipping appts comprises upper strata oar (7), bottom oar (8), it is characterized in that the size of the size of bottom oar (8) greater than upper strata oar (7).
2, the blade of decomposer whipping appts according to claim 1, it is characterized in that described bottom oar (8) is made of oar (3) in outer oar (4) of bottom and the bottom, upper strata oar (7) is made of oar (1) in oar outside the upper strata (2) and the upper strata, and the size of oar (3) is greater than the corresponding size of oar (1) in oar outside the upper strata (2) and the upper strata in outer oar (4) of bottom and the bottom.
3, the blade of decomposer whipping appts according to claim 2 is characterized in that the blade lower length of the outer oar (4) of described bottom is longer than blade upper length.
