Description

Technical Field

[0001] The utility model relates to the technical field of spiral mixers, in particular to a spiral mixer with uniform mixing. Background Art

[0002] The spiral mixer is mainly used to mix granular or powdered materials, and is mainly used in the fields of medicine and food. The existing spiral mixer includes a conical spiral mixer, and its main principle is that a rotatable screw is provided inside a conical barrel, and the screw can rotate along the axis of the conical barrel while rotating. The material inside the conical barrel is mixed up and down under the action of the screw. The existing conical spiral mixer has the problem that the conical spiral mixer generally requires three motors to cooperate, one of which is used to drive the two screws to revolve, and the other two motors are used to control the two screws to rotate, which leads to high cost and complex structure. Based on the above situation, it is necessary to design a spiral mixer with uniform mixing to solve the above problems. Utility Model Content

[0003] The utility model provides a spiral mixer for uniformly mixing materials, so as to solve the problems that the spiral mixer in the prior art has a relatively complex structure and a high manufacturing cost.

[0004] The technical problem solved by the utility model is achieved by the following technical solutions:

[0005] A spiral mixer for uniform mixing comprises a mixing box with a hollow chamber inside, a motor arranged at one end of the mixing box, and a spiral conveying rod located at the output end of the motor and inside the hollow chamber. The hollow chamber inside the mixing box comprises a conveying chamber fitted with the spiral conveying rod and a return chamber located above the conveying chamber. The mixing box as a whole is inclined relative to a horizontal line, and the conveying direction of the spiral conveying rod is from a lower direction of the mixing box to a higher direction of the mixing box.

[0006] Preferably, a feed inlet is provided at a central position of the mixing box, and the feed inlet is located at a central position of an upper surface of the mixing box.

[0007] Preferably, a telescopic rod is fixedly connected to the outer wall of the mixing box, a discharge port is provided at one end of the mixing box at a higher position, a cover plate is provided at the position of the discharge port, and the end of the telescopic rod is fixedly connected to the cover plate.

[0008] Preferably, support legs are provided on the outside of the mixing box, and the mixing box is maintained in an inclined state by the support legs.

[0009] Preferably, a transparent window is provided on the side wall of the mixing box, and a loading height indicator line is provided on one side of the transparent window.

[0010] Preferably, the inclination angle of the mixing box is between thirty degrees and sixty degrees.

[0011] The beneficial effect of the utility model is that by arranging an inclined mixing box, a spiral conveying rod and a motor, the material inside the mixing box can be transported from the bottom of the mixing box to the high point of the mixing box and then slide down to the low point of the mixing box by the spiral conveying rod, thereby repeatedly achieving uniform mixing of the materials. It can be seen that uniform mixing of the materials can be achieved by only using a spiral conveying rod and a mixing box. Compared with the traditional conical spiral mixer, the structure is simpler and the cost is lower. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0019] Reference Figure 1-Figure 4As shown, a spiral mixer for uniform mixing includes a mixing box 1 with a hollow chamber 2 inside, a motor 3 arranged at one end of the mixing box 1 and a spiral conveying rod 4 at the output end of the motor 3 and inside the hollow chamber 2, the hollow chamber 2 inside the mixing box 1 includes a conveying chamber 201 fitted with the spiral conveying rod 4 and a return chamber 202 above the conveying chamber 201, the mixing box 1 is arranged to be inclined relative to the horizontal line as a whole, and the conveying direction of the spiral conveying rod 4 is from the lower direction of the mixing box 1 to the higher direction of the mixing box 1.

[0020] Specifically, refer to Figure 1 and Figure 3 First, start the motor 3, and the motor 3 drives the spiral conveying rod 4 to rotate. Under the action of the spiral conveying rod 4 and the conveying chamber 201, the material inside the mixing box 1 is transported from the lower part of the conveying chamber 201 of the mixing box 1 to the higher part of the conveying chamber 201 of the mixing box 1. Since the mixing box 1 is in a closed state, the material transported upward will gradually accumulate at the highest point of the return chamber 202 of the mixing box 1. Under the action of gravity, the material inside the return chamber 202 will slide down to the lower part of the return chamber 202, so that the material reciprocates in the process of upward transportation and sliding down, so as to achieve the effect of fully mixing the material. The cross-section of the conveying chamber 201 is semicircular, which can be fitted with the spiral conveying rod 4 to ensure the normal rise of the material, and the cross-section of the return chamber 202 can be rectangular or other shapes. The inner top wall of the return chamber 202 does not contact the upper part of the spiral conveying rod 4 and has a spacing, so that the material accumulated on the upper part of the mixing box 1 can slide down to realize the return of the material, and the material can be evenly mixed in the process of upward transportation and sliding down.

[0021] Furthermore, a feed inlet 5 is provided at the central position of the mixing box 1 , and the feed inlet 5 is located at the central position of the upper surface of the mixing box 1 .

[0022] Among them, Figure 2 As shown, the feed port 5 is arranged at the center of the upper surface to avoid full filling, which causes the material to be unable to slide down and affects the mixing effect.

[0023] Furthermore, a telescopic rod 8 is fixedly connected to the outer wall of the mixing box 1 , a discharge port 10 is provided at one end of the mixing box 1 at a higher position, a cover plate 9 is provided at the position of the discharge port 10 , and the end of the telescopic rod 8 is fixedly connected to the cover plate 9 .

[0024] Among them, Figure 4 As shown, after the materials are mixed evenly, the cover plate 9 is driven to separate from the discharge port 10 by the telescopic rod 8, and the spiral conveying rod 4 can drive the materials to be discharged from the discharge port 10, thereby realizing the discharge process.

[0025] Furthermore, support legs 11 are provided outside the mixing box 1 , and the mixing box 1 is maintained in an inclined state by the support legs 11 .

[0026] Among them, Figure 4 As shown, the mixing box 1 is placed in an inclined state by the support legs 11, which can ensure that the inclination of the mixing box 1 is stable.

[0027] Furthermore, a transparent window 6 is provided on the side wall of the mixing box 1 , and a loading height indicator line 7 is provided on one side of the transparent window 6 .

[0028] Among them, Figure 2 As shown, a transparent window 6 is provided on the side wall of the mixing box 1 to facilitate observation of the material mixing state inside the mixing box 1. At the same time, a filling height indicator line 7 is provided on one side of the mixing box 1 to facilitate control of the material filling amount during the filling process to avoid overfilling or underfilling of the material, which affects the mixing effect. Figure 2 There are two middle loading height indicator lines 7, corresponding to the lowest loading height and the highest loading height respectively.

[0029] Furthermore, the inclination angle of the mixing box 1 is between thirty degrees and sixty degrees.

[0030] Among them, Figure 1-Figure 4 As shown, a smaller inclination angle of the mixing box 1 is not conducive to the material sliding down from the top, and a larger inclination angle of the mixing box 1 is not conducive to the upward transportation of the material. Therefore, setting the inclination state of the mixing box 1 between thirty and sixty degrees is more effective.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
