Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of concrete admixture production, and specifically relates to mixing equipment for concrete admixture production. Background Art
[0002] Concrete admixtures refer to chemical substances added during the concrete mixing process to improve the performance of concrete. They are also called concrete chemical admixtures. When mixing the raw materials for the production of concrete admixtures, the raw materials are generally added to a mixing barrel and stirred by a stirring rod driven by a drive motor.
[0003] The mixing barrel in the prior art usually uses an auxiliary motor connected to a single stirring shaft for rotation and stirring. However, the single-shaft stirring method is prone to produce stirring dead angles, and the stirring rod has a limited coverage area, making it difficult to fully mix the production raw materials, affecting the quality of the produced concrete admixture products. Utility Model Content
[0004] The purpose of the utility model is to provide a mixing device for producing concrete admixtures, so as to solve the problems mentioned in the background technology.
[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:
[0006] A mixing device for producing concrete admixtures, comprising a barrel, a horizontal frame is installed on the upper side of the barrel, a fixed column is installed on the lower side of the middle part of the horizontal frame, and a stirring mechanism is installed on the lower side of the fixed column;
[0007] The stirring mechanism includes a rotating block, and two symmetrically distributed stirring rods are rotatably installed on the lower side of the rotating block. Stirring plates are installed at intervals on the lower sides of the two stirring rods, and the stirring plates on the upper sides of the two stirring rods are staggered and do not interfere with each other. A transmission assembly for driving the rotating block and the stirring rods is installed on the upper side of the barrel body.
[0008] The transmission assembly includes a driven sprocket, and the number of the driven sprockets is two, and they correspond to the two stirring rods. The driven sprocket is rotatably installed on the inner side of the rotating block and is transmission connected to the corresponding stirring rods. A driving sprocket is rotatably connected to the rotating block and fixedly connected to the fixed column at the middle part of the inner side of the rotating block. A chain is transmission connected between the driving sprocket and the two driven sprockets. A first gear fixedly connected to the rotating block is rotatably installed on the upper side of the fixed column, and a second gear meshing with the first gear is rotatably installed on the side of the first gear. A motor is installed on the upper side of the cross frame, and the output end of the motor is transmission connected to the second gear.
[0009] The diameter and number of teeth of the driving sprocket are both greater than those of the driven sprocket.
[0010] On the front and back sides of the rotating block, two stirring rods fixedly connected to the rotating block are symmetrically installed. An inclined deflector plate is installed on the lower side of the stirring rod, and the inclination direction of the deflector plate on the lower side of the stirring rod is the same.
[0011] An L-shaped rod fixedly connected to the rotating block is installed on the side of the stirring mechanism. Cleaning brushes are evenly installed on the side and bottom of the L-shaped rod, and the cleaning brushes are in contact with the side wall and bottom of the barrel body.
[0012] The transmission component enables the stirring rod and the stirring plate to rotate around their own axes while rotating around the axis of the barrel body to stir the admixture inside the barrel body, thereby improving the mixing efficiency of the mixing equipment. The mutually staggered stirring plates can increase the coverage range of the stirring mechanism, thus avoiding the problem that the admixture in the stirring dead corner cannot be fully mixed, thereby improving the production quality of the concrete admixture. The cooperation of the driving sprocket, the driven sprocket and the chain enables the transmission component to rotate around its own axis while ensuring that the stirring rod can rotate around its own axis during work, and also makes the structure of the transmission component simple and the failure rate low. Therefore, the required maintenance workload and maintenance cost are correspondingly reduced. At the same time, problems such as friction, wear and looseness between complex components are reduced, and the reliability of the equipment is improved. The design that the diameter and number of teeth of the driving sprocket are both greater than those of the driven sprocket enables the stirring rod and the stirring plate to increase their rotation speed during revolution, thereby further increasing the mixing efficiency of the admixture solution. The deflector plate on the lower side of the stirring rod on one side can upwardly divert the admixture solution when the rotating block rotates, and the deflector plate on the other side can downwardly divert the admixture solution inside the barrel body when the rotating block rotates, so that the admixture inside the barrel body is more evenly mixed up and down. The L-shaped rod and the cleaning brushes can brush the side wall and bottom of the barrel body when the rotating block rotates, preventing the admixture raw material from adhering to the side wall of the barrel body, thereby affecting the mixing quality of the admixture. At the same time, the cleaning brushes can facilitate the cleaning of the inside of the barrel body after use, thereby improving the use convenience of the equipment.

[0020] In order to enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below in conjunction with the drawings and embodiments.
[0021] As Figures 1-5 shown, a mixing device for producing concrete admixtures includes a barrel body 1, a horizontal frame 11 is installed on the upper side of the barrel body 1, a fixed column 12 is installed on the lower side of the middle part of the horizontal frame 11, and a stirring mechanism is installed on the lower side of the fixed column 12;
[0022] The stirring mechanism includes a rotating block 13, two symmetrically distributed stirring rods 14 are rotatably installed on the lower side of the rotating block 13, stirring plates 15 are installed at intervals up and down on the lower sides of the two stirring rods 14, and the stirring plates 15 on the upper sides of the two stirring rods 14 are staggered with each other and do not interfere with each other. A transmission assembly for driving the rotating block 13 and the stirring rods 14 is installed on the upper side of the barrel body 1.
[0023] When the present utility model is in use, the admixture raw materials to be mixed are added to the inner side of the barrel body 1. The rotation of the rotating block 13 can drive the rotation of the stirring rods 14, and at the same time, the transmission assembly can enable the stirring rods 14 to rotate around the fixed column 12 while rotating on their own axes.
[0024] The transmission assembly enables the stirring rods 14 and the stirring plates 15 to rotate on their own axes while stirring the admixtures inside the barrel body 1 during revolution, thereby improving the mixing efficiency of the mixing device. The staggered stirring plates 15 can increase the coverage range of the stirring mechanism, thereby avoiding the problem that the admixtures in the stirring dead corners cannot be mixed completely, and thus improving the production quality of concrete admixtures.
[0025] The transmission assembly includes a driven sprocket 2. The number of driven sprockets 2 is two, corresponding to two stirring rods 14. The driven sprockets 2 are rotatably installed inside the rotating block 13 and are in transmission connection with the corresponding stirring rods 14. In the middle of the inside of the rotating block 13, a driving sprocket 21 is installed, which is rotatably connected to the rotating block 13 and fixedly connected to the fixed column 12. A chain 22 is in transmission connection between the driving sprocket 21 and the two driven sprockets 2. On the upper side of the fixed column 12, a first gear 23 rotatably connected to the rotating block 13 is installed. A second gear 24 meshing with the first gear 23 is rotatably installed on the side of the first gear 23. An electric motor 25 is installed on the upper side of the cross frame 11, and the output end of the electric motor 25 is in transmission connection with the second gear 24.
[0026] When the transmission assembly works, the electric motor 25 drives the second gear 24 to rotate, thus driving the rotating block 13 to rotate. Since both the fixed column 12 and the driving sprocket 21 are fixedly connected to the cross frame 11, when the rotating block 13 rotates, the driving sprocket 21 rotates relative to the rotating block 13, thereby driving the driven sprocket 2 to rotate.
[0027] The cooperation of the driving sprocket 21, the driven sprocket 2 and the chain 22 enables the transmission assembly to ensure that the stirring rod 14 can rotate self - when working, and at the same time makes the structure of the transmission assembly simple and the failure rate low. Therefore, the required maintenance workload and maintenance cost are also correspondingly reduced. At the same time, problems such as friction, wear and loosening between complex components are reduced, improving the reliability of the equipment.
[0028] Both the diameter and the number of teeth of the driving sprocket 21 are larger than those of the driven sprocket 2.
[0029] The design that both the diameter and the number of teeth of the driving sprocket 21 are larger than those of the driven sprocket 2 enables the stirring rod 14 and the stirring plate 15 to increase the speed of their self - rotation when revolving, thereby further increasing the mixing efficiency of the admixture solution.
[0030] On the front and rear sides of the rotating block 13, two stirring rods 4 fixedly connected to the rotating block 13 are symmetrically installed. On the lower side of the stirring rod 4, a deflector plate 41 that is inclined left - and - right is installed, and has the same inclination direction as the deflector plate 41 on the lower side of the stirring rod 4.
[0031] The deflector plate 41 on the lower side of one stirring rod 4 can upwardly deflect the admixture solution when the rotating block 13 rotates, and the deflector plate 41 on the other side can downwardly deflect the admixture solution inside the barrel 1 when the rotating block 13 rotates, so that the admixture inside the barrel 1 is mixed more evenly up and down, thereby further improving the mixing quality of the equipment.
[0032] On the side of the stirring mechanism, an L - shaped rod 5 fixedly connected to the rotating block 13 is installed. Cleaning brushes 51 are evenly installed on the side and bottom of the L - shaped rod 5, and the cleaning brushes 51 are in contact with the side wall and the bottom of the barrel 1.
[0033] The L-shaped rod 5 and the cleaning brush 51 can brush the side wall and the bottom of the barrel body 1 when the rotating block 13 rotates, preventing the admixture raw materials from adhering to the side wall of the barrel body 1, thereby affecting the mixing quality of the admixture. At the same time, the cleaning brush 51 can conveniently clean the inside of the barrel body 1 after use, thereby improving the convenience of using the equipment.
[0034] The above embodiments merely exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
