Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of binder processing technology, especially relates to a binder stirring device. BACKGROUND

[0002] In the field of production and manufacture of binders, processing and stirring are extremely critical links. This process requires that various raw materials be mixed according to precise formula proportions to promote their uniform dispersion and full integration. To achieve this goal, special stirring equipment is usually used, such as a common stirrer. The stirrer generates strong mechanical force through the high-speed rotation of the stirring paddle, which promotes various raw materials to flow vigorously, roll continuously, and collide frequently in the stirring container. This not only ensures that different forms of raw materials, such as solid resins, fillers, and liquid solvents, plasticizers, etc., are in full contact, achieving uniform distribution of each component in the system and effectively avoiding local concentration anomalies. At the same time, it greatly promotes the chemical reactions in the system, such as the full reaction of the curing agent with the resin, thereby precisely controlling the key properties of the binder, including viscosity, curing time, and strength, etc., and ultimately producing a binder product with stable performance that fully meets the use requirements.

[0003] With the continuous development of the industry, higher requirements are placed on the performance and operational convenience of binder processing and stirring equipment. Many technical researches are dedicated to improving the mixing efficiency, product quality, and convenience of cleaning and maintenance of the equipment. Among them, the binder mixing and stirring device disclosed in Chinese Patent No. "CN214416291U" brings new ideas to the industry. The device is equipped with a base, a stirring and mixing box, and a drive motor. The base is vertically provided with a support plate. The stirring and mixing box is detachably connected to the base, and an opening is provided on the side away from the base. The drive motor can slide along the support plate towards or away from the base. The stirring shaft connected by the drive motor is provided with stirring blades for stirring materials. The stirring blades can work deeply in the stirring and mixing box. This device provides convenience for cleaning the inside of the stirring and mixing box to a certain extent and has a certain degree of innovation.

[0004] However, upon closer examination of the performance of this device in actual application scenarios, it is not difficult to find that it has significant limitations. Although this device can be adjusted up and down to provide some convenience for cleaning operations, after the tank body is opened, the stirring and mixing structure is still suspended at the top of the tank body, which seriously hinders the subsequent comprehensive cleaning of the inside of the tank body. Moreover, when cleaning the stirring and mixing mechanism, the generated wastewater will directly fall into the tank body, further increasing the complexity and difficulty of cleaning. This design flaw, which cannot move the stirring structure to the side of the tank body, greatly restricts the efficient development of equipment cleaning work and cannot meet the strict requirements of modern production for rapid and convenient maintenance of equipment. Therefore, it needs to be improved and designed. Utility model content

[0029] Principle and advantages: The device is provided with a height adjusting mechanism 3, which can significantly optimize the cleaning and maintenance process of the equipment. During use, start the first motor 31, and after the first motor 31 is running, drive the first screw rod 32 to rotate. Since the first screw rod 32 is matched with the sliding block 33 through threads, the rotation of the first screw rod 32 can accurately drive the sliding block 33 to slide smoothly inside the vertical rail 2. The sliding of the sliding block 33 drives the connecting frame 34 to move upwards, thereby promoting the top cover 63 and the stirring assembly 66 connected thereto to move upwards synchronously, realizing the complete extraction of the stirring assembly 66 from the inside of the tank body 4. This operation enables efficient cleaning and maintenance of the inside of the tank body 4 and the stirring mechanism 6. After completing the movement adjustment, start the second motor 622, and when the second motor 622 is running, drive the second screw rod 623 to rotate. The rotation of the second screw rod 623 drives the sliding block 624 to slide inside the horizontal rail 621. Through the sliding of the sliding block 624 inside the horizontal rail 621, the top cover 63 and the stirring assembly 66 connected to the bottom thereof can be accurately adjusted to the top of the collection frame 81. At this time, the stirring assembly 66 can be thoroughly cleaned. The wastewater generated during the cleaning process can be effectively collected through the collection frame 81. The collected wastewater can be smoothly discharged through the opening of the drain valve 82 and the use of the drain pipe 83. By moving the stirring assembly 66 away from the tank body 4, favorable conditions are created for the thorough cleaning of the inside of the tank body 4, greatly improving the convenience of the device in daily use.

[0030] By setting the stirring mechanism 6, during the stirring and mixing process of the binder, the required raw materials can be accurately added into the inside of the tank body 4 with the guidance of the feeding hopper 65 and the feeding pipe 64. Then start the third motor 661, and when the third motor 661 is running, drive the rotating shaft 662 to rotate. The rotation of the rotating shaft 662 synchronously drives the stirring auger 663, the stirring rod 664, and the scraping frame 665 to rotate together. The stirring auger 663 is located at the bottom of the tank body 4, and during its rotation process, it can effectively drive the solution to surge upwards, promoting the materials inside the tank body 4 to roll up and down, forming a good convection mixing effect. At the same time, the rotating shaft 662 drives the stirring rod 664 to rotate, which stirs and mixes the solution inside the tank body 4 in all directions, significantly enhancing the stirring function of the equipment. During the stirring process, the stirring rod 664 continuously rotates, further stirring the materials inside the tank body 4 in detail. In addition, the rotating shaft 662 drives the scraping frame 665 to rotate, and the outer side of the scraping frame 665 closely fits the inner wall of the tank body 4. During the rotation process, it can effectively scrape and clean the inner wall of the tank body 4, ensuring that the inside of the tank body 4 always remains clean during the stirring process. When it is necessary to discharge the raw materials after stirring, only need to start the third motor 661 in reverse, and the third motor 661 can drive the stirring auger 663 to rotate in reverse, making the mixed solution flow downwards. At this time, open the discharge valve 5, and the stirred materials can be quickly discharged through the discharge pipe 7, fully demonstrating the excellent stirring and mixing function of the equipment.
