Description

Technical Field

[0001] The utility model relates to the technical field of feed machinery, in particular to a mixing and anti-agglomeration powder stirring device. Background Art

[0002] In the process of feed processing, powder mixing is a necessary process. Its main purpose is to mix different powders evenly, form new powders, and enrich the nutritional content of feed.

[0003] In the process of mixing some powders, liquids need to be added, such as water, nutrient solution and other liquid components. When the liquid is introduced, the mixing of the powder will cause lumps to form, which not only affects the degree of mixing, but also affects the quality of the output.

[0004] The current mainstream solution is to increase the density and coverage area of ​​the stirring blades in the mixing equipment to increase the cutting density of the agglomerated powder during the mixing process, minimize the agglomerate volume, and improve the mixing effect. However, increasing the density of the stirring blades will increase the complexity of the structure, which is not very conducive to subsequent repair and maintenance.

[0005] In order to solve the above problems, people have been seeking an ideal technical solution. Utility Model Content

[0006] The utility model aims to provide a mixing and anti-agglomeration powder stirring device for solving the problem of powder agglomeration and improving the mixing effect in view of the deficiencies in the prior art.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a mixed anti-agglomeration powder stirring device, including a bracket, a stirring bin, a stirring shaft, a stirring motor and a stirring blade;

[0008] The stirring bin is a horizontally arranged cylindrical bin body, a horizontally extending cylindrical inner cavity is arranged in the cylindrical bin body, the stirring bin is fixed on the bracket as a whole, one end of the stirring bin is connected to the feed inlet and the liquid inlet, and the other end is connected to the discharge port;

[0009] The two ends of the stirring shaft are respectively rotatably sealed with the two ends of the cylindrical bin body, and the stirring motor is installed on the bracket or the outside of the stirring bin to drive the stirring shaft to rotate;

[0010] The stirring blades are distributed on the stirring shaft, and the stirring blades include a first blade and a second blade. The rotary cutting thrust of the first blade is set from the inlet end to the outlet end of the stirring chamber, and the rotary cutting thrust of the second blade is set from the outlet end to the inlet end of the stirring chamber. Among all the stirring blades, the number of first blades is greater than the number of second blades.

[0011] Based on the above, the rotation angle of two adjacent stirring blades in the axial direction is ≥60°.

[0012] Based on the above, the rotation angle of two stirring blades adjacent to each other in the axial direction is 90°.

[0013] Based on the above, the rotation directions of the two adjacent stirring blades located on the same straight line are opposite.

[0014] Based on the above, the stirring blade further includes a third blade, the rotary cutting thrust of the third blade is zero, and the third blade is distributed in the central area of ​​the stirring shaft.

[0015] Based on the above, the number ratio of the first blades, the second blades and the third blades is 4:3:3.

[0016] Based on the above, the blade inclination angles of the first blade and the second blade are between 30° and 60°.

[0017] Based on the above, an inspection door is provided on the outer side of the mixing bin, the upper end of the inspection door is hinged to the outer side of the mixing bin by a hinge, and a lock is provided on the lower end of the mixing bin corresponding to the inspection door.

[0018] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0019] 1. The horizontally arranged mixing bin and mixing shaft are used to change the powder mixing path from the traditional vertical mixing to the horizontal mixing. The powder moves more slowly in the horizontal direction and is mixed more fully.

[0020] 2. On the basis of horizontal stirring, the stirring blades are designed to be two blades with opposite rotary thrusts. During the mixing process, the powder does not move continuously, but is affected by the interaction of the forward thrust and the reverse thrust, which continuously makes the material move forward and backward in a short distance. The stroke of the powder is further greatly improved, the travel speed is reduced, and the mutual friction efficiency between the powders is also greatly improved, which can minimize the agglomeration rate and improve the stirring effect. Since the overall rotary thrust is toward the outlet side, the evenly mixed material is finally sent out. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0026] Example 1

[0027] like Figure 1 and Figure 3 As shown, a mixed anti-agglomeration powder stirring device comprises a bracket 1, a stirring bin 2, a stirring shaft 3, a stirring motor 4 and a stirring blade 5;

[0028] The stirring bin 2 is a horizontally arranged cylindrical bin body, in which a horizontally extending cylindrical inner cavity is arranged. The stirring bin 2 is fixed on the bracket 1 as a whole, and one end of the stirring bin 2 is connected to the feed port 6 and the liquid inlet 7, and the other end is connected to the discharge port 8.

[0029] The two ends of the stirring shaft 3 are respectively rotatably sealed with the two ends of the cylindrical bin body, and the stirring motor 4 is installed on the outside of the bracket 1 or the stirring bin 2 to drive the stirring shaft 3 to rotate.

[0030] The stirring blades 5 are distributed on the stirring shaft 3, and the stirring blades 4 include a first blade 41 and a second blade 42. The rotary cutting thrust of the first blade 41 is set from the inlet end to the outlet end of the stirring chamber 2, and the rotary cutting thrust of the second blade 42 is set from the outlet end to the inlet end of the stirring chamber 2. Among all the stirring blades, the number of first blades 41 is greater than the number of second blades 42.

[0031] It should be noted that the rotary cutting thrust refers to the horizontal thrust generated by the stirring blade 4 in the rotating state. The blade inclination angles of the first blade and the second blade are between 30° and 60°.

[0032] Working principle description:

[0033] The powder enters from the feed port 6 and the liquid enters from the liquid inlet 7. The powder and liquid entering the mixing chamber 2 are preliminarily mixed and, under the stirring action of the stirring shaft and the stirring blades 5, they are mixed while moving horizontally.

[0034] During the moving process, since the rotary cutting thrust directions of the first blade 41 and the second blade 42 are opposite, a part of the mixture of powder and liquid is moved forward by the influence of the first blade 41 within a short distance, and the other part is moved backward by the influence of the second blade 42. The two parts of powder and liquid blend and mix with each other, and finally the agglomeration rate of the powder is reduced and the stirring effect is improved.

[0035] Since the number of the first blades 41 is larger than the number of the second blades 42 as a whole, and under the dual effect of the feeding thrust at the feeding end, the material can be smoothly discharged from one side of the discharge port.

[0036] In this embodiment, the rotation angle of two adjacent stirring blades in the axial direction is 90°.

[0037] To increase the blade density, in some embodiments, the rotation angle of two adjacent stirring blades in the axial direction is ≥60°.

[0038] In other embodiments, an inspection door is provided on the outside of the mixing bin, and the upper end of the inspection door is hinged to the outside of the mixing bin by a hinge. A lock is provided on the lower end of the inspection door corresponding to the mixing bin, which can be opened to inspect the internal mixing blades and clean the environment inside the bin.

[0039] Example 2

[0040] like Figure 1 As shown, the main difference between this embodiment and embodiment 1 is that the two adjacent stirring blades located on the same straight line have opposite rotation directions, which can evenly control the law of force distribution during the movement of the powder and control the unit stroke of the reciprocating movement.

[0041] Example 3

[0042] like Figure 2 As shown, the main difference between this embodiment and embodiments 1 and 2 is that the stirring blade further includes a third blade 43, the rotary cutting thrust of the third blade 43 is zero, and the third blade 43 is distributed in the central area of ​​the stirring shaft.

[0043] The number ratio of the first blades 41 , the second blades 42 and the third blades 43 is 4:3:3.

[0044] The third blade is located in the center and mainly plays the role of fully cutting the agglomerated powder. Its distribution density can also be appropriately increased.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
