Description

Technical Field

[0001] This utility model relates to the field of cement fly ash, specifically to a mixer. Background Technology

[0002] Although some existing mixers have multiple spiral ribbons on the mixing shaft, the rotation direction of the multiple ribbons is the same, all pushing water and materials towards the discharge port, which leads to poor mixing effect. Utility Model Content

[0003] The purpose of this invention is to provide a horizontal ribbon high-efficiency agitator to solve the above-mentioned technical problems.

[0004] A horizontal high-efficiency ribbon mixer includes a mixing chamber, a mixing shaft inside the mixing chamber, support rods evenly spaced on the mixing shaft, and ribbons fixed on the support rods. There are two ribbons: an outer ribbon fixed to the end of the support rod and an inner ribbon fixed to the middle of the support rod. The outer ribbon and the inner ribbon have opposite spiral directions.

[0005] Preferably, the mixing chamber has a discharge port at the lower left end, a feed port at the upper right end, and a water inlet at the lower right end. The outer spiral ribbon pushes the water and material towards the feed port, and the inner spiral ribbon pushes the water and material towards the discharge port.

[0006] Preferably, the horizontal ribbon high-efficiency agitator further includes a left baffle, on which a central hole is formed, and the agitator shaft passes through the central hole;

[0007] The outer contour of the portion of the left baffle located below the stirring shaft is semi-circular, and its outer diameter is equal to the inner diameter of the stirring chamber. The outer edge of the portion of the left baffle located below the stirring shaft is connected to the inner wall of the stirring chamber.

[0008] The outer contour of the portion of the left baffle located above the stirring shaft is semi-circular, and its outer diameter is larger than the outer diameter of the inner spiral ribbon but smaller than the outer diameter of the outer spiral ribbon. A gap is provided between the outer edge of the portion of the left baffle located above the stirring shaft and the inner wall of the stirring chamber.

[0009] The discharge port is located between the left baffle and the left end face of the stirring chamber.

[0010] Preferably, the width of the outer spiral is the same everywhere, and the width of the inner spiral gradually decreases from left to right.

[0011] Beneficial effects: 1. The outer and inner spiral directions of the spiral ribbons in this invention are opposite, thereby effectively improving the mixing effect. 2. The addition of a left baffle in this invention can effectively restrict the movement direction of water and materials, further improving the mixing effect. Attached Figure Description

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0015] Reference Figure 1 , Figure 2 A horizontal spiral ribbon high-efficiency agitator includes a mixing chamber. A discharge port 10 is located at the lower left end of the mixing chamber, a discharge port 13 is located at the upper right end of the mixing chamber, and a water inlet 12 is located at the lower right end of the mixing chamber. An exhaust port 11 is located at the upper left end of the mixing chamber. Alternatively, an observation window 9 is located at the upper left end of the mixing chamber. Preferably, the observation window 9 is located directly above the discharge port 13.

[0016] The horizontal ribbon high-efficiency agitator also includes a drive motor 1, located outside the mixing chamber. The drive motor 1's shaft is connected to a mixing shaft 6 located inside the mixing chamber via a connecting shaft 2. Thus, the drive motor 1 drives the mixing shaft 6 inside the mixing chamber to rotate. Preferably, the drive motor 1 is located on the right side of the mixing chamber. The connecting shaft 2 passes through the right end face of the mixing chamber, and a mechanical seal 4 is provided at the junction of the connecting shaft 2 and the right end face to prevent material from escaping from this point. A self-aligning tapered roller bearing assembly 3 is provided between the drive motor 1 and the mixing chamber to ensure that the central axes of the drive motor 1, the connecting shaft 2, and the mixing shaft 6 are aligned in a straight line.

[0017] A support rod is provided on the stirring shaft 6, and two spiral ribbons 14 are fixed on the support rod: an outer spiral ribbon 7 fixed to the end of the support rod and an inner spiral ribbon 8 fixed to the middle of the support rod. The spiral directions of the outer spiral ribbon 7 and the inner spiral ribbon 8 are opposite. The outer spiral ribbon 7 pushes water and materials towards the lower feed port 13, and the inner spiral ribbon 8 pushes water and materials towards the discharge port 10, thereby improving the mixing effect. The support rods are preferably arranged at equal intervals, so that the pitch of the inner spiral ribbon 8 and the outer spiral ribbon 7 is the same. The width of the outer spiral ribbon 7 is preferably the same everywhere, and the width of the inner spiral ribbon 8 is preferably gradually decreasing from left to right. Therefore, the width of the inner spiral ribbon 8 is larger closer to the discharge port 10, and the pushing force is greater. The inner diameter of the inner spiral ribbon 8 can be the same everywhere, and the outer diameter can increase with the increase of the width. The outer diameter of the inner spiral ribbon 8 is preferably smaller than the inner diameter of the outer spiral ribbon 7, so that there are still gaps at the intersection of the spiral ribbons for materials to pass through.

[0018] The horizontal spiral ribbon high-efficiency agitator also includes a left baffle with a central hole through which the agitator shaft 6 passes. The outer contour of the portion of the left baffle below the agitator shaft 6 is semi-circular, and its outer diameter is equal to the inner diameter of the agitator chamber. The outer contour of the portion of the left baffle above the agitator shaft 6 is also semi-circular, and its outer diameter is larger than the outer diameter of the inner spiral ribbon 8 but smaller than the outer diameter of the outer spiral ribbon 7. The outer edge of the portion of the left baffle below the agitator shaft 6 is connected to the inner wall of the agitator chamber. A gap is provided between the outer edge of the portion of the left baffle above the agitator shaft 6 and the inner wall of the agitator chamber. This utilizes the baffle to restrict the movement direction of water and materials, especially water, to improve the agitation effect. A gap is provided between the left baffle and the left end face of the agitator chamber, and the discharge port 10 is located at the gap. The exhaust port is located on the right side of the left baffle.

[0019] A spiral pusher plate 5 is fitted onto the connecting shaft 2, located between the spiral ribbon and the right end face of the housing, directly above the water inlet 12. This spiral pusher plate pushes water to the material. The horizontal spiral ribbon high-efficiency agitator may also include a circular right baffle, fitted around the agitator shaft 6 or connecting shaft 2. A gap exists between the inner edge of the right baffle and the agitator shaft 6 or connecting shaft 2, and the outer edge of the right baffle is connected to the inner wall of the housing. This right baffle restricts the movement direction of water and material, thereby improving the agitation effect.

[0020] The mixing chamber may also be equipped with a water distribution pipe, with the water inlet 12 connected to the water distribution pipe. The water distribution pipe has a water outlet and is fixed to the inner wall of the mixing chamber. The extension direction of the water distribution pipe is the same as the extension direction of the mixing shaft 6. This allows the water to be dispersed through the water distribution pipe, thereby improving the mixing effect. After mixing is completed, the mixing shaft can also be rinsed using the water distribution pipe.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
