Abstract
Description
Technical Field
[0001] This utility model relates to the field of sulfoaluminate cement processing technology, and in particular to a mixing and stirring device for sulfoaluminate cement admixtures. Background Technology
[0002] In modern technical materials, sulfoaluminate cement is a commonly used type of cement, which requires the use of admixtures such as glucose, sodium carbonate, monomers, and sodium bicarbonate.
[0003] After adding admixtures, sulfoaluminate cement needs to be thoroughly mixed. During the mixing process, the mixing paddle directly stirs the sulfoaluminate cement by rotating the rotor. However, the mixing paddle is usually located at the end of the rotor. When the rotor drives the mixing paddle to rotate at high speed, the end of the rotor is prone to surging. This causes the mixing paddle to directly contact the inner wall of the mixing tank, increasing the wear of the mixing paddle and shortening the service life of the mixing equipment.

Detailed Implementation
[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] This utility model provides, for example Figures 1-3 The illustrated sulfoaluminate cement admixture mixing equipment includes a mixing tank 101, a mixing mechanism, a support mechanism, and a discharge mechanism. The mixing mechanism is located inside the mixing tank 101, and the support mechanism is located at the bottom of the mixing mechanism and connected to it. The discharge mechanism is located at the bottom of the mixing tank 101. During the mixing process, admixtures including glucose, sodium carbonate, monomers, and sodium bicarbonate need to be added to the mixing tank 101. Glucose is an organic retarder. The support mechanism provides limiting support for the high-speed rotation of the mixing mechanism, making it less prone to surging during high-speed rotation. This improves the stability of the mixing mechanism's operation, reduces friction between the mixing mechanism and the inner wall of the mixing tank 101, and extends the service life of the mixing mechanism.
[0036] The stirring mechanism includes a rotating rod 201 and a stirring paddle 202. The rotating rod 201 is rotatably disposed inside the mixing tank 101, and the stirring paddle 202 is fixedly connected to the outer wall of the rotating rod 201. The rotation of the rotating rod 201 drives the stirring paddle 202 to rotate, so that the materials in the mixing tank 101 can be mixed and stirred by the stirring paddle 202.
[0037] The discharge mechanism includes a discharge hole 301, a discharge pipe 302, and a valve 303. The discharge hole 301 is located at the bottom of the mixing tank 101, and the discharge pipe 302 is fixedly connected to the bottom of the mixing tank 101. The interior of the discharge hole 301 is connected to the interior of the discharge pipe 302. The valve 303 is installed inside the discharge pipe 302. The sulfoaluminate cement after mixing is discharged from the mixing tank 101 through the discharge hole 301 and the discharge pipe 302.
[0038] The support mechanism includes a connecting hole 401, a connecting rod 402, and a contact mechanism. The connecting rod 402 is located at the bottom of the inner cavity of the mixing tank 101. A fixing mechanism is provided between the connecting rod 402 and the inner wall of the discharge hole 301. The connecting hole 401 is located at the bottom end of the rotating rod 201. The outer wall of the connecting rod 402 is movably connected to the inner wall of the connecting hole 401. The contact mechanism is located on the inner wall of the connecting hole 401. Before the mixing tank starts working, the rotating rod 201 will descend so that the connecting rod 402 is inserted into the connecting hole 401. This allows the rotating rod 201 to rotate and drive the stirring paddle 202 to rotate for mixing. Through the mutual limiting of the connecting rod 402 and the connecting hole 401, the bottom end of the rotating rod 201 is not prone to slippage, thus improving the stability of the rotating rod 201. This also makes it less likely for the stirring paddle 202 to swing when rotating, thus avoiding direct contact between the stirring paddle 202 and the inner wall of the mixing tank 101 when rotating, thereby improving the stability of the mixing mechanism.
[0039] The contact mechanism includes a ball hole 601 and a rolling ball 602. The ball hole 601 is opened on the inner wall of the connecting hole 401, and the rolling ball 602 is movably locked inside the ball hole 601. The outer wall of the rolling ball 602 is fitted against the outer wall of the connecting rod 402. When the connecting rod 402 is inserted into the connecting hole 401, the rolling ball 602 will adhere to the inner wall of the connecting rod 402, so that the rolling ball 602 will roll during the rotation of the rotating rod 201, thereby reducing the friction generated when the rotating rod 201 rotates, and making the rotating rod 201 rotate more smoothly.
[0040] The fixing mechanism includes multiple fixing rods 501, which are fixedly connected to the outer wall of the connecting hole 401 at intervals. The ends of the multiple fixing rods 501 away from the connecting rod 402 are respectively fixedly connected to the inner wall of the discharge hole 301. The connecting rod 402 is fixed by the fixing rods 501 to ensure the stability of the support mechanism. At the same time, the fixing rods 501 will not block the sulfoaluminate cement from passing through the discharge hole 301.
[0041] The top end of the connecting rod 402 is fixedly connected to a guide block 701, which is conical in shape. The conical guide block 701 guides the connecting rod 402 into the connecting hole 401, so that the connecting rod 402 can be stably inserted into the connecting hole 401.
[0042] A rubber sleeve 801 is attached to the bottom of the inner wall of the connecting hole 401. The inner wall of the rubber sleeve 801 is interference-fitted with the outer wall of the connecting rod 402. The rubber sleeve 801 can seal the gap between the connecting hole 401 and the connecting rod 402, so that the material will not enter the interior of the connecting hole 401 and come into contact with the ball 602, thereby ensuring the stability of the contact mechanism.
[0043] The mixing tank 101 has a lid 901 at its top, and a servo motor 902 is mounted on the top of the lid 901. The output end of the servo motor 902 is connected to the top of the rotating rod 201. The bottom of the lid 901 has an annular groove 903. The top of the mixing tank 101 is fixedly connected to a ring 904. The outer wall of the ring 904 is movably connected to the inner wall of the annular groove 903. When the lid 901 is placed on top of the mixing tank 101, the ring 904 is first inserted into the annular groove 903. At this time, the connecting rod 402 has not yet been inserted into the connecting hole 401. As the lid 901 continues to move down, the connecting rod 402 can be stably inserted into the connecting hole 401, thus ensuring that the support mechanism can work stably. The stirring mechanism can work stably by working through the servo motor 902. The servo motor 902 is electrically connected to an external power supply through an external switch, which makes it easy for the operator to control the servo motor 902, thereby improving the stability and convenience of the servo motor 902.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
