Description

Technical Field

[0001] This utility model relates to the field of mixing tanks, and in particular to a premixing mixing device with a guide tube. Background Technology

[0002] A mixing tank is an industrial container used for mixing, stirring, or homogenizing materials, widely used in industries such as chemical, food, pharmaceutical, and building materials. It is typically made of stainless steel, carbon steel, or plastic and equipped with an electric motor-driven stirring device (such as a paddle or spiral belt) to uniformly mix different components or promote chemical reactions through rotation. Some mixing tanks have heating, cooling, or vacuum functions to meet specific process requirements. Its structure includes the tank body, stirring system, transmission device, and auxiliary components, with capacities ranging from a few liters to several cubic meters, and can be customized to meet production needs. Features include high-efficiency mixing, ease of operation, and easy cleaning, making it a key piece of equipment in mass production.

[0003] A search revealed patent publication number CN219922810U, which discloses a mixing tank, including a main body and support legs mounted below it. The tank is characterized by a bracket mounted on its main body, eccentrically positioned to the main body. A motor is mounted on the bracket within the mixing tank, and a connecting rod is positioned below the motor. An impeller is mounted on the lower surface of the connecting rod. A T-shaped outer shell is embedded in the main body, and a baffle is located within the T-shaped shell. A connecting block is mounted on one side of the baffle, a rack is mounted on one side of the connecting block, and a gear is mounted on one side of the rack. A second motor is mounted on the lower surface of the gear. This invention solves the problem of vortices easily forming inside the mixing tank during use. These vortices not only cause abnormal vibrations in the mixing tank but also reduce mixing efficiency, resulting in unsatisfactory material mixing and, in severe cases, damage to the mixing tank.

[0004] While existing technologies can achieve a certain mixing effect during use, they suffer from the drawback of lacking an efficient premixing function, which reduces the mixing effect. In view of this, we propose a premixing and mixing device with a guide tube, which solves the above-mentioned problem. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a premixing and stirring device with a guide tube.

[0006] The technical solution of this utility model is as follows: A premixing and stirring device with a guide tube includes a box, a pipe, a top cover, a universal joint one and a universal joint two. A pipe is provided on one side of the box, and a spiral lifting cylinder is provided inside the pipe. A stirring frame two is provided at the lower end of the spiral lifting cylinder. Universal joint one is fixed at the lower end of the spiral lifting cylinder, and universal joint two is fixed at the upper end of the stirring frame two. Universal joint one and universal joint two are rotatably connected by a rotating ball. Stirring frame one is provided inside the box. Stirring frame one has an offset design, and the pipe has a bent design.

[0007] This device utilizes a two-section pipeline design to achieve material flow. The upper vertical section houses a rotating spiral cylinder that can crush large materials without easily causing blockages. After crushing, the material enters the lower section of the pipeline, where a second stirring rack rotates to further disperse the material. The material is then guided into the housing, where a motor drives the first stirring rack to rotate continuously, achieving thorough mixing. This device provides a preliminary material guidance process, preventing excessive clumping during thorough mixing and optimizing the mixing effect, thus demonstrating high practicality.

[0008] Preferably, a top cover is fixed to the upper end of the box, and a motor is fixed to the middle of the upper end of the top cover. The output shaft of the motor is fixedly connected to the rotation center of the upper end of the stirring frame. The fixed design of the top cover and the motor enhances the structural stability of the equipment. At the same time, the motor directly drives the stirring frame, which simplifies the transmission structure, reduces the failure rate, and ensures the efficient transmission of stirring power, thereby maintaining a continuous stirring effect.

[0009] Preferably, the lower end of the box is provided with a discharge port, and the upper end of the top cover is fixed with a handle. The design of the discharge port facilitates the rapid discharge of materials and improves production efficiency. The addition of the handle facilitates the opening and maintenance of the top cover, while the combination of the bracket and the base improves the overall stability of the equipment and avoids displacement caused by vibration, making it suitable for industrial continuous operation scenarios.

[0010] Preferably, the outer wall of the chamber is provided with a support, the lower end of the support is fixed with a base, and a controller is provided on one side of the chamber. The integration of the controller enables precise control of the motor speed and the stirring process. Users can adjust the parameters according to the material characteristics to further optimize the stirring quality. At the same time, the combined design of the support and the base disperses the load on the chamber and extends the service life of the equipment.

[0011] Preferably, a reinforcing beam is provided between the pipe and the box. The addition of the reinforcing beam significantly improves the mechanical strength of the connection between the pipe and the box, preventing the interface from loosening or leaking due to long-term vibration. It is especially suitable for high-load operating environments and ensures the long-term reliability of the equipment.

[0012] Preferably, the pipe is provided with mounting plate one and mounting plate two. The stirring rack two is rotatably mounted on one side of mounting plate two, and the spiral lifting cylinder is rotatably mounted on the lower end of the mounting plate. Mounting plate one and mounting plate two are used to mount the spiral lifting cylinder and the stirring rack two. The independent drive of motor two ensures that the stirring rack two and the spiral lifting cylinder operate efficiently, realizing the initial multi-stage processing of materials.

[0013] Preferably, the upper end of the pipe is designed with a wide opening, and a motor is provided on one side of the mounting plate. The output shaft of the motor is fixedly connected to the rotation center of one side of the mixing frame. The wide opening design of the pipe facilitates the initial input of materials and reduces splashing. The independent control of the motor allows for flexible adjustment of the rotation speed of the mixing frame and the spiral lifting cylinder according to the characteristics of the materials, so as to achieve fine crushing, which is especially suitable for the mixing needs of complex components.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model achieves automatic material diversion and preliminary crushing functions through a two-stage pipeline design and a spiral lifting cylinder structure. The rotation of the spiral lifting cylinder can effectively crush large pieces of material and prevent blockage; the secondary dispersion of the second mixing rack further optimizes the uniformity of the material, while the offset design of the first mixing rack ensures that the material in the tank is fully mixed.

[0016] II. Based on the first beneficial effect, this design systematically solves the problems of agglomeration, blockage, and uneven mixing in material mixing through multi-level innovative design (such as segmented pipelines, spiral crusher, and dual-stirring linkage). The modular structure (mounting plate, reinforcing beam) and user-friendly design (handle, controller) balance durability and ease of operation, while details such as separate motor control and wide-mouth feeding further expand its applicability. The overall solution improves mixing efficiency while reducing maintenance costs, demonstrating high practicality.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
