Description

TECHNICAL FIELD

[0001] The utility model relates to ceramic production technical field especially is related to a kind of mixing device for preparing infrared mullite ceramic. BACKGROUND

[0002] In the field of ceramic production, especially for the preparation of infrared mullite ceramic, the mixing process is one of the key steps to ensure product quality and performance. For example, Chinese patent (announcement number: CN114644513A) discloses a preparation method of mullite infrared transparent ceramic, which needs to prepare mixed powder by aluminum oxide and silicon dioxide in a molar ratio of 1.70~1.94:1 during the preparation of infrared mullite ceramic.

[0003] However, the existing batching device generally adds two kinds of powder into the mixing barrel in turn, and then stirs and mixes the powder. This way, because the powder in contact with the inner wall of the mixing barrel is almost not contacted by the stirring shaft, it is easy to have a stirring dead angle (local accumulation phenomenon), which is not conducive to uniform mixing, so it usually needs a long stirring time, and the mixing effect is not ideal.

[0004] Therefore, we designed a kind of mixing device for preparing infrared mullite ceramic, which improves the stirring efficiency and makes the powder mixture uniform by reciprocating the mixing barrel during stirring. UTILITY MODEL CONTENT

[0005] In order to overcome the deficiencies in the background art, the utility model discloses a kind of mixing device for preparing infrared mullite ceramic.

[0006] To achieve the above-mentioned utility model purposes, the utility model adopts the following technical solutions:

[0007] A kind of mixing device for preparing infrared mullite ceramic, comprising:

[0008] A fixed frame;

[0009] A mixing barrel is installed on the fixed frame, and a stirring shaft is provided in the mixing barrel for stirring raw materials to mix multiple raw materials uniformly;

[0010] A drive device is provided with two output shafts, one of which is connected to the stirring shaft through a universal coupling, and the other output shaft is connected to the mixing barrel through a linkage mechanism for reciprocating the mixing barrel.

[0011] Preferably, the upper end of the stirring shaft protrudes out of the mixing barrel and is connected to the top wall of the mixing barrel through a bearing, ensuring smooth rotation of the stirring shaft and preventing shaking during operation.

[0012] Preferably, the driving device comprises a motor and a reducer with two output shafts of different transmission ratios, wherein the high-speed rotating output shaft is connected with the stirring shaft, and the low-speed rotating output shaft is connected with the linkage mechanism.

[0013] Preferably, the linkage mechanism comprises a crank or a cam for intermittently pressing the mixing barrel to make reciprocating overturning movement under the action of gravity.

[0014] Preferably, the linkage mechanism comprises a connecting rod, a vertically arranged sliding rod and a guide rod, the sliding rod is slidably connected between the fixed frame and the sliding rod, and the sliding direction is perpendicular to the rotating direction of the mixing barrel, wherein the lower end of the sliding rod is provided with a bent portion for intermittently pressing the mixing barrel to make reciprocating overturning movement under the action of gravity.

[0015] Preferably, the outer end of the bent portion is provided with a roller to reduce the friction and wear between the mixing barrel and the bent portion.

[0016] Preferably, the outer end of the bent portion is provided with a trunnion, and one side of the mixing barrel is provided with a strip-shaped hole, the trunnion passes through the strip-shaped hole to realize the connection between the mixing barrel and the bent portion, so that the sliding rod can push or pull the mixing barrel to overturn during reciprocating movement.

[0017] Due to the adoption of the technical scheme as described above, the utility model has the following beneficial effects:

[0018] 1. By driving the stirring shaft to rotate at high speed while using the linkage mechanism to make the mixing barrel reciprocate and overturn, the material can not only be fully stirred in the horizontal direction, but also flow along with the overturning of the mixing barrel in the vertical direction, avoiding the occurrence of local accumulation of the material and ensuring the uniformity of the material mixing. This double movement mode greatly improves the contact frequency and dispersion degree between the materials, thereby realizing a more efficient mixing process.

[0019] 2. For the relative movement between the bent portion and the mixing barrel, the friction between the two can be effectively reduced by the roller or the trunnion, the wear speed of the mechanical parts is reduced, and the service life of the equipment is prolonged.

[0028] Further, the upper end of the stirring shaft 3 extends out of the mixing barrel 2; in order to ensure the smoothness of the rotation of the stirring shaft 3 and prevent the stirring shaft 3 from shaking during operation, the shaft body of the stirring shaft 3 is connected with the top wall of the stirring barrel through a bearing.

[0029] The fixed frame 1 is also provided with a driving device 4 equipped with two output shafts, one of the output shafts of the driving device 4 is connected with the upper end of the stirring shaft 3 through a universal coupling 5; that is, during the operation of the driving device 4, the output shaft can drive the stirring shaft 3 to rotate, thereby stirring the raw materials in the mixing barrel 2, so that the raw materials in the mixing barrel 2 are mixed uniformly.

[0031] According to the need, the driving device 4 includes a motor and a reducer with two output shafts, the motor drives the reducer to operate, and then the two output shafts of the reducer rotate simultaneously.

[0032] According to the need, since the stirring shaft 3 needs to rotate at high speed when stirring the material, the speed reducer adopts different transmission ratios between its two output shafts and its input shaft, specifically, the output shaft with high rotating speed is connected with the stirring shaft 3.

[0033] The other output shaft of the driving device 4 is connected with the mixing barrel 2 through the linkage mechanism 6, and is used to drive the mixing barrel 2 to make reciprocating overturning movement.
