Abstract
The utility model relates to a stirring paddle for reaction kettles, and the stirring paddle comprises a stirring shaft, an upper impeller and a lower impeller, wherein the upper and lower impellers are arranged on the stirring shaft, the upper impeller is positioned above the lower impeller, the upper impeller comprises an upper hub and an upper blade, the upper blade is arranged on the upper hub, the lower impeller comprises a lower hub and a lower blade, and the lower blade is arranged on the lower hub. Compared with the prior art, the stirring paddle disclosed by the utility model has the following advantages and effects: the stirring paddle is provided with two impellers, compared with a situation that only an impeller adopted in the prior art, the stirring effect is good, reaction liquid in a kettle is stirred more uniformly, the liquid mixing degree is improved, the reaction effect is better, and the color rates of pigments are improved; and the tilting directions of the upper impeller and the lower impeller are opposite, due to the rotation of the upper impeller, reaction liquid in a kettle radially flows downward, due to the rotation of the lower impeller, reaction liquid in the kettle radially flows upward, and the two liquid flows flow oppositely and are contacted, thereby promoting the mixing.
Description
The art field
The utility model relates to a kind of reactor paddle, for the preparation of pigment Yellow 14, pigment red 112, pigment yellow 13, pigment yellow 83, paratonere F3RK, benzidine yellow G, paratonere 57:1, pigment red 146, pigment red 4 8:2, paratonere F5RK, pigment red 21, pale purple source, pigment orange 13, paratonere 53:1 are in the reactor of pigment yellow 74 or pigment red 4 9:1.
Background technology
In the process of preparation pigment, particularly prepare pigment Yellow 14, pigment red 112, pigment yellow 13, pigment yellow 83, paratonere F3RK, benzidine yellow G, paratonere 57:1, pigment red 146, pigment red 4 8:2, paratonere F5RK, pigment red 21, pale purple source, pigment orange 13, paratonere 53:1, in the process of pigment yellow 74 or pigment red 4 9:1, reaction liquid in the still need to be stirred, to improve reaction efficiency.But existing paddle is only installed an impeller, and mixing effect is not good, easily causes the pigment coloring rate excessively low, affects product quality.
The utility model content
The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, and mixing effect is good, makes that reaction liquid stirs in the still, can improve the reactor paddle of pigment coloring rate.
The technical scheme in the invention for solving the above technical problem is: this reactor paddle, it is characterized in that: comprise shaft, upper impeller and lower impeller, upper impeller and lower impeller all are installed on the shaft, described upper impeller is positioned at lower impeller top, described upper impeller comprises wheel hub and blade, described blade is installed on the wheel hub, and described lower impeller comprises lower hub and lower blade, and described lower blade is installed on the lower hub.
The quantity of blade described in the utility model is three.
The quantity of lower blade described in the utility model is three.
The incline direction of blade described in the utility model and lower blade is opposite.
The utility model compared with prior art has the following advantages and effect: have two impellers, than an impeller of prior art, mixing effect is good, makes in the still reaction liquid stir more even, improves the liquid degree of mixing, make reaction effect more, improve the tinctorial yield of pigment.The incline direction of blade and lower blade is opposite, and upper wheel rotation makes in the still reaction liquid diametrically toward dirty, lower wheel rotation make in the still reaction liquid in the footpath downward stream up, two strands of liquid flow and contact in opposite directions, promote to mix.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Label declaration: shaft 1, upper impeller 2, lower impeller 3, blade 4, lower blade 5.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 1, the reactor paddle of the present embodiment comprises shaft 1, upper impeller 2 and lower impeller 3.
Upper impeller 2 and lower impeller 3 all are installed on the shaft 1, and upper impeller 2 is positioned at lower impeller 3 tops, and upper impeller 2 comprises wheel hub and blade 4, and blade 4 is installed on the wheel hub, and lower impeller 3 comprises lower hub and lower blade 5, and lower blade 5 is installed on the lower hub.
The quantity of blade 4 is three.In the utility model, the quantity of blade 4 can be two, four, five or six.
The quantity of lower blade 5 is three.In the utility model, the quantity of lower blade 5 can be two, four, five or six.
The incline direction of blade 4 and lower blade 5 refers on the contrary: overlook shaft 1 for turning clockwise, the normal direction in the front of blade 4 is oblique upper, and the normal direction in the front of lower blade 5 is oblique below.Surface the preceding when the front of blade 4 and lower blade 5 refers to move.
In the time of the utility model work, shaft 1 turns clockwise, and upper impeller 2 and lower impeller 3 all for clockwise rotating, rotate for right-to-left among Fig. 1.Upper impeller 2 and lower impeller 3 be reaction liquid in the stirred tank all, makes it mix.At shaft 1 radially, upper impeller 2 makes in the still reaction liquid to dirty, and lower impeller 3 makes that reaction liquid is to the upper reaches in the still, and two strands of liquid collide mutually, improve mixed effect.
Above content described in this specification only is to the explanation of the utility model structure example.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
Claims (4)
