Description

Technical Field

[0001] This utility model belongs to the technical field of mixing equipment, and in particular relates to a mixing shaft structure. Background Technology

[0002] As the core transmission component of mixing equipment, the stirring shaft is designed to efficiently and stably transmit power from the drive unit to the agitator to meet the process requirements of mixing and heat transfer. A complete stirring shaft mainly consists of the shaft body, the shaft end connection, and auxiliary supports. The shaft body is the main body that transmits torque and bears bending moment, and can be divided into solid and hollow types. The latter has better rigidity for the same weight. The shaft end is connected to the drive unit through a coupling and reliably fixed to the agitator through threads, flanges, or keyways. However, the stirring shaft structure still has the following drawbacks in actual use:

[0003] During the production process, the stirring shaft structure is directly installed in a suitable position using installation equipment. However, its overall structure is uniformly arranged, and the external structure includes stirring blades. During the stirring process, the blades are easily affected by uneven movement of materials, resulting in insufficient stability of the stirring shaft during stirring.

[0004] Secondly, during operation, the stirring shaft structure is installed together with the mounting structure via bolts or pins. As it rotates, these bolts or pins can easily loosen, affecting the stability of the stirring shaft structure. Utility Model Content

[0005] The purpose of this utility model is to provide a stirring shaft structure that solves the problems of unstable stirring caused by the blades being easily disturbed during the rotation of the stirring shaft structure, and the unstable installation of the stirring shaft structure, which easily affects the stability of the stirring shaft in use.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a stirring shaft structure, comprising a fixed cylinder, a central vertical rod, and a fixed disc. A connecting pipe is fixedly connected to the upper periphery of the fixed cylinder, and a fixed pipe is fixedly connected to the lower periphery of the fixed cylinder. A central vertical rod is fixed between the connecting pipe and the fixed pipe. The top of the central vertical rod extends beyond the top of the connecting pipe, and a fixed disc is mounted on the top of the central vertical rod. A fixing pin is fixed to the bottom of the fixed disc. The fixed cylinder serves as the main support structure, with its upper part fixedly connected to the central vertical rod via the connecting pipe and its lower part via the fixed pipe. The central vertical rod extends upward through the connecting pipe and connects to the fixed disc. A fixing pin is provided at the bottom of the fixed disc to cooperate with the top of the central vertical rod to transmit torque and achieve power transmission.

[0008] Furthermore, connecting rods are symmetrically fixed around the fixed cylinders on both sides of the connecting pipe. A stirring blade is fixed to the end of each connecting rod away from the fixed cylinder. Connecting rods are symmetrically installed on the fixed cylinders on both sides of the connecting pipe. A stirring blade is fixed to the outer end of each connecting rod. When the fixed cylinder rotates with the central vertical rod, it drives the stirring blade to rotate, thereby achieving the stirring effect on the material in the container.

[0009] Furthermore, the central vertical rod passes vertically through the fixed cylinder, and a fastening bolt is threadedly connected to the bottom end of the central vertical rod. The central vertical rod passes vertically through the fixed cylinder, and its bottom end is connected to the fastening bolt through the thread. The fastening bolt plays a counterweight role during rotation, thereby improving the operational stability of the central vertical rod and the entire stirring structure.

[0010] Furthermore, a mounting plate is fixed around the central vertical rod above the connecting pipe. The mounting plate is fixed to the top of the connecting pipe. The mounting plate has vertically penetrating mounting holes arranged in a circular array inside. A mounting plate is fixed around the outer periphery of the central vertical rod above the connecting pipe. Multiple mounting holes are evenly opened along the circular edge of the mounting plate for subsequent connection and fixation with the fixing plate.

[0011] Furthermore, a pin opening is provided at the top of the central vertical rod, and the fixing pin at the bottom of the fixed plate is inserted into the pin opening. A rotating shaft is fixed at the top of the fixed plate, and the pin opening at the top of the central vertical rod cooperates with the fixing pin at the bottom of the fixed plate to achieve synchronous rotation of the two. A rotating shaft is provided at the top of the fixed plate for connecting to external power equipment and transmitting torque.

[0012] Furthermore, the bottom end of the fixed plate is provided with a ring array of plug-in screws. The plug-in screws are inserted into the mounting holes of the mounting plate and extend out of the bottom end of the mounting plate. The plug-in screws at the bottom end of the mounting plate are threaded with fastening nuts. The bottom of the fixed plate is provided with multiple plug-in screws. After being inserted into the mounting holes on the mounting plate, they are locked from below by fastening nuts. This structure ensures a firm connection between the fixed plate and the central vertical rod and the fixed cylinder, improving the coaxiality of the transmission and the overall rigidity.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of unstable mixing caused by the blades being easily disturbed during the rotation of the stirring shaft structure by setting a fixed cylinder and a central vertical rod. First, a fastening bolt is installed at the bottom end of the central vertical rod. Then, the fastening bolt is screwed to the bottom end of the central vertical rod. After pressing the bottom end of the fixed tube with the bottom end of the central vertical rod and the bottom end of the fixed tube, the central vertical rod is counterweighted during operation. As the central vertical rod rotates, it drives the fixed cylinder, connecting rod and stirring blades to rotate. The counterweight of the fastening bolt increases the stability of the central vertical rod during the overall operation.

[0015] This invention solves the problem of unstable installation of the stirring shaft, which easily affects the stability of the stirring shaft's operation, by setting up a fixed cylinder, a central vertical rod, and a fixed plate. When installing the fixed cylinder and the central vertical rod to the bottom of the fixed plate, first align the pin at the top of the central vertical rod with the fixing pin at the bottom of the fixed plate, and then insert the connecting screw at the bottom of the fixed plate into the mounting hole on the mounting plate. Then, tighten the fastening nut to the bottom of the connecting screw and rotate it until it is pressed tightly against the mounting plate. During this process, the pin at the top of the central vertical rod is fitted onto the outside of the fixing pin, which makes the installation of the fixed cylinder, connecting pipe, central vertical rod, and fixed plate tight, increases the coaxiality of the shaft rotation and the central vertical rod rotation, and ensures the stability of the stirring shaft in use.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0025] Please see Figure 1-4 This utility model is a stirring shaft structure, including a fixed cylinder 1, a central vertical rod 2, and a fixed plate 3. A connecting pipe 104 is fixedly connected to the upper periphery of the fixed cylinder 1, and the connecting rod 101 and the stirring blade 102 are connected to the fixed cylinder 1. A fixed pipe 103 is fixedly connected to the lower periphery of the fixed cylinder 1. The central vertical rod 2 is installed in the connection between the connecting pipe 104 and the fixed pipe 103 to increase the central strength. The central vertical rod 2 is fixed together between the connecting pipe 104 and the fixed pipe 103. The central vertical rod 2 increases the strength of the fixed cylinder 1, the fixed pipe 103, and the connecting pipe 104. The top end of the central vertical rod 2 extends out of the top end of the connecting pipe 104. The top end of the central vertical rod 2 is provided with a fixed plate 3. When the fixed plate 3 is in operation, it drives the mounting plate 202, the connecting pipe 104, and the central vertical rod 2 to rotate synchronously. A fixing pin 301 is fixed at the bottom end of the fixed plate 3. After the fixing pin 301 is inserted into the central vertical rod 2, it drives the fixed cylinder 1 and the central vertical rod 2 to rotate.

[0026] Specifically, connecting rods 101 are symmetrically fixed around the fixed cylinders 1 on both sides of the connecting pipe 104. A stirring blade 102 is fixed at the end of each connecting rod 101 away from the fixed cylinder 1. The connecting pipe 104 fixes the stirring blade 102 through the connecting rods 101. As the stirring blade 102 rotates, it stirs the material in the corresponding container.

[0027] Furthermore, the central vertical rod 2 passes vertically through the fixed cylinder 1, and the bottom end of the central vertical rod 2 is threaded with a fastening bolt 201. The central vertical rod 2 is counterweighted at the bottom end by the fastening bolt 201, which increases the working stability of the central vertical rod 2.

[0028] The operation process of this embodiment is as follows: During operation, firstly, the bottom end of the central vertical rod 2 is rotated and fastened with the fastening bolt 201. Then, the fastening bolt 201 is screwed to the bottom end of the central vertical rod 2. After the bottom end of the fixing tube 103 is pressed against the bottom end of the central vertical rod 2 and the bottom end of the fixing tube 103, the central vertical rod 2 is counterweighted during operation. As the central vertical rod 2 rotates, it drives the fixing cylinder 1, the connecting rod 101 and the stirring blade 102 to rotate. The counterweight of the fastening bolt 201 increases the stability of the central vertical rod 2 during overall operation. Specific Implementation Example 2

[0029] Please see Figure 1 , 2 3, 5. Based on the first specific embodiment, a mounting plate 202 is fixed around the central vertical rod 2 above the connecting pipe 104. The mounting plate 202 is fixed to the top of the connecting pipe 104. The mounting plate 202 has vertically through mounting holes 203 arranged in a ring array. The connecting pipe 104 and the central vertical rod 2 are movably connected to the insertion screw 302 for installation through the mounting holes 203 on the mounting plate 202.

[0030] Specifically, the top of the central vertical rod 2 is provided with a pin hole 204, and the fixing pin 301 at the bottom of the fixing plate 3 is inserted into the pin hole 204. The top of the fixing plate 3 is fixed with a rotating shaft 304. The central vertical rod 2 is movably connected to the fixing pin 301 through the pin hole 204. The top of the rotating shaft 304 at the top of the fixing plate 3 is connected to the output end of the external power equipment. When the external power equipment drives the rotating shaft 304 to rotate, it drives the central vertical rod 2 and the fixing plate 3 to rotate.

[0031] Furthermore, the bottom end of the fixed plate 3 is provided with a ring array of insertion screws 302. The insertion screws 302 are inserted into the mounting holes 203 of the mounting plate 202 and extend out of the bottom end of the mounting plate 202. The insertion screws 302 at the bottom end of the mounting plate 202 are threaded with fastening nuts 303. After the fixed plate 3 is inserted into the mounting holes 203 on the mounting plate 202 through the insertion screws 302, the fastening nuts 303 are screwed on until the insertion screws 302 and the bottom end of the mounting plate 202 abut against each other, thus installing the central vertical rod 2 and the fixed plate 3 together.

[0032] The operation process of this embodiment is as follows: When installing the fixed cylinder 1 and the central vertical rod 2 to the bottom of the fixed plate 3, first align the pin port 204 at the top of the central vertical rod 2 with the fixing pin 301 at the bottom of the fixed plate 3, and insert the plug screw 302 at the bottom of the fixed plate 3 into the mounting hole 203 on the mounting plate 202. Then, screw the fastening nut 303 to the bottom of the plug screw 302 and rotate it until it is pressed against the mounting plate 202. During this process, after the pin port 204 at the top of the central vertical rod 2 is fitted onto the outside of the fixing pin 301, the fixed cylinder 1, the connecting pipe 104, the central vertical rod 2 and the fixed plate 3 are installed and secured, increasing the coaxiality of the rotation of the rotating shaft 304 and the rotation of the central vertical rod 2.
