Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a mixer for preparing a concrete anti-mud agent. Background Art

[0002] Concrete admixtures refer to substances added during the production of building materials such as concrete, cement, and gypsum, which can improve the performance of the materials or accelerate the reaction. There are many types of admixtures, including plasticizers, water reducers, air entraining agents, waterproofing agents, etc. Each type of admixture has its specific function. Concrete admixtures also include anti-mud agents, which refer to substances added to improve and adjust the performance of concrete. The application of concrete admixtures in engineering has received more and more attention. The addition of admixtures plays a certain role in improving the performance of concrete. Anti-mud agents are additives that can improve the fluidity and stability of mud. Their main function is to reduce the viscosity of mud, improve the fluidity of mud, and prevent the sedimentation and stratification of mud. In some cases, anti-mud agents are also regarded as a type of water reducer, especially in concrete applications, which can prevent concrete from mudding and ensure the quality of concrete.

[0003] The patent with application number 202221407164.2 discloses a mixer for preparing anti-cracking and anti-corrosion concrete admixtures, including a base plate, a vertical pole, a mixing tank, a feeding device, a discharging cover, a stirring device and a shaking device, the vertical pole is arranged on the base plate, the mixing tank is hingedly arranged on the vertical pole, the feeding device is arranged on the mixing tank, the discharging cover is arranged at one end of the mixing tank, the stirring device is arranged on the mixing tank, and the shaking device is arranged on the vertical pole and connected to the mixing tank; the shaking device includes a sleeve, a guide rod, a spring, a motor one, a gear one, a gear two and a rocker.

[0004] The above scheme solves the problem that most of the existing stirring and mixing equipment only has a stirring function. Since there may be a lot of admixtures, it is difficult for the stirring rod to blend the admixtures in the upper and lower layers. The above scheme achieves the purpose of more uniform mixing by shaking the mixing tank up and down, but the amplitude of shaking the mixing tank up and down is small, so it is impossible to completely ensure the full mixing of the concrete anti-mud agent and other raw materials, which in turn affects the production quality of the concrete anti-mud agent.

DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

The first motor 601 is installed on the bottom surface of the annular plate 3, the rotating column 605 is fixedly connected to the bottom surface of the mixing tank 5, and the second motor 607 is installed on the upper surface of the mixing tank 5. The output end of the first motor 601 is installed with a first rotating shaft 602, and the first rotating shaft 602 is rotatably connected to the inside of the annular plate 3. The top of the first rotating shaft 602 is fixedly connected with a first gear 603, and the outer surface of the first gear 603 is meshed with a second gear 604, and the second gear 604 is fixedly connected to the outer surface of the mixing tank 5. The output end of the second motor 607 is installed with a second rotating shaft 608, and the outer surface of the second rotating shaft 608 is fixedly connected with a group of stirring rods 609, and the second rotating shaft 608 is rotatably connected to the inside of the mixing tank 5. The bottom end of the rotating column 605 is installed with a bearing seat 606, and the bearing seat 606 is rotatably connected to the inside of the base 1, and the bottom end of the rotating column 605 is rotatably connected to the base 1.

[0024] The base 1 is the basic structure of the entire mixer and provides a stable support for the mixer. The support rod 2 is fixed on the base 1 and plays a supporting role, supporting the annular plate 3 and the protective shell 4.

[0025] The annular plate 3 is connected to the top of the support rod 2 to provide a mounting position for the reverse positive stirring mechanism 6 and the mixing tank 5. The protective shell 4 is fixed on the annular plate 3 to protect the reverse positive stirring mechanism 6 and prevent dust and debris from entering. The mixing tank 5 is the main container for mixing the concrete anti-mud agent with other raw materials. The reverse positive stirring mechanism 6 is the core part of the mixer, ensuring that the concrete anti-mud agent can be fully mixed with other raw materials.

[0026] The first motor 601 provides power for the reverse stirring mechanism 6. The first rotating shaft 602 connects the first motor 601 and the first gear 603 to transmit the rotational torque. The first gear 603 is connected to the first rotating shaft 602 to realize the reversal function of the mixing tank 5. The second gear 604 is fixed on the mixing tank 5, meshing with the first gear 603, driving the mixing tank to reverse. The rotating column 605 connects the mixing tank 5 and the base 1 to support the mixing tank 5. The bearing seat 606 is installed in the base 1 and connected to the rotating column 605 to provide rotation support. The second motor 607 provides power for the stirring rod 609 to realize the stirring function. The second rotating shaft 608 connects the second motor 607 and the stirring rod 609. The stirring rod 609 is fixed on the second rotating shaft 608 to stir the raw materials inside the mixing tank 5.

[0028] The second electric valve 10 is installed on the discharge pipe 9 to control the discharge of the mixed concrete anti-mud agent.

[0029] Working principle: When using the mixer for preparing concrete anti-mud agent, firstly, the raw materials are added into the mixing tank 5 through the feeding hopper 7, and then the first motor 601 and the second motor 607 are started. When the first motor 601 is working, it drives the first shaft 602 and the first gear 603 to rotate. Since the first gear 603 and the second gear 604 are meshed, the first gear 603 will drive the second gear 604 and the mixing tank 5 to rotate in the opposite direction when it rotates. When the second motor 607 is working, it drives the second shaft 608 and the stirring rod 609 to rotate, and the raw materials in the mixing tank 5 are positively stirred. The reverse rotation of the mixing tank 5 and the positive stirring of the stirring rod 609 make the mixing of the raw materials more uniform, thereby improving the production quality of the concrete anti-mud agent. After the mixing is completed, the first electric valve 8 and the second electric valve 10 are opened to discharge the mixed anti-mud agent. By setting the reverse positive stirring mechanism 6, the problem that most of the existing stirring and mixing equipment has only a single stirring function and the stirring rod 609 is difficult to fully mix the raw materials of the upper and lower layers due to the large amount of raw materials is solved.

[0030] 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 spirit and principles of the present invention should be included in the protection scope of the present invention.
