The stirring barrel 1 is the main container for stirring operation, which provides sufficient stirring space for the material and ensures the smooth progress of the stirring process.
[0026] The driving control device 7, especially the driving motor 72 therein, provides a powerful power source for the entire stirring device. The driving motor 72 is connected to the connecting shaft 73 through its bottom output shaft, realizing stable power transmission and ensuring efficient operation of the stirring device.
[0027] The connection of the bottom end of the connecting shaft 73 and the rotary connecting device 8 constitutes the core transmission part of the stirring device. The rotary connecting device 8 transmits power to the stirring chain through the plurality of connecting frames 9 connected to the outside of the bottom rotating shaft 83, realizing omnidirectional stirring of the material.
[0028] The hinged design of the pin shaft 10 arranged in the connecting frame 9 and the rotating chain 11 enables the rotating chain to swing flexibly during stirring, adapting to the stirring needs of different materials and improving the uniformity and efficiency of stirring. This flexible stirring method effectively avoids stirring dead angles and ensures high-quality mixing of the material.
[0029] In this embodiment, the rotary connecting device 8 comprises a support protection cylinder 81 fixed to the inner wall of the top of the stirring barrel 1, a sliding rod 84 arranged in the inside of the support protection cylinder 81, a sliding groove 75 arranged at the bottom end of the connecting shaft 73, the top end of the sliding rod 84 vertically slidingly matched with the sliding groove 75, and the bottom end of the sliding rod 84 fixedly connected with the rotating shaft 83. The sliding groove 75 at the bottom end of the connecting shaft 73 vertically slidingly matches with the sliding rod 84, realizing flexible connection and stable transmission between the connecting shaft 73 and the rotating shaft 83. This design enables the rotating shaft 83 to rotate stably during stirring while allowing certain axial sliding, improving the adaptability and stability of the stirring device.
[0030] Specifically, the sliding rod 84 is connected with a connecting column 85, a reciprocating threaded groove 86 is formed in the support protection cylinder 81, and the connecting column 85 is slidingly arranged in the reciprocating threaded groove 86. This design not only enhances the stability of the sliding rod 84, but also enables the sliding rod 84 to move reciprocally along a specific trajectory during stirring through the guiding action of the reciprocating threaded groove 86. This reciprocating motion combined with the rotating motion further improves the uniformity and efficiency of stirring.
[0031] Further, the cross section of the sliding rod 84 is rectangular structure, the cross section shape of the sliding groove 75 is matched with the cross section shape of the sliding rod 84, and the connecting column 85 is provided in cylindrical shape. The design ensures the stable sliding of the sliding rod 84 in the sliding groove 75, prevents the shaking or jamming phenomenon caused by the shape mismatch. At the same time, the connecting column 85 is provided in cylindrical shape, which facilitates the smooth sliding in the reciprocating threaded groove 86, improves the reliability and durability of the stirring device.
[0032] Further, the rotating sealing sleeve 82 is installed between the inner wall of the bottom of the support protection cylinder 81 and the outer wall of the rotating shaft 83. The leakage of the material during the stirring process is effectively prevented, and the cleaning and stirring effect in the stirring barrel 1 are ensured. At the same time, the rotating sealing sleeve 82 can also withstand a certain pressure and friction, prolonging the service life of the stirring device.
[0033] Further, the shell of the driving motor 72 is installed on the top of the stirring barrel 1 through the fixing frame 71, and the connecting shaft 73 is rotatably connected with the top of the stirring barrel 1 through the bearing 74. The friction and wear of the connecting shaft 73 during rotation are reduced, and the operation efficiency and stability of the stirring device are improved.
[0034] Further, the feeding hopper 2 is installed on one side of the top of the stirring barrel 1, which facilitates the feeding of the material into the stirring barrel 1; the feeding hole 3 is provided on the top, which provides convenience for adding a small amount or special material. The bottom end of the discharge pipe 4 is horizontally directed outward, which is convenient for connecting with the conveying pipeline or conveying pump, etc., and facilitates the discharge of the stirred material. At the same time, the support leg 5 is installed on the outside of the bottom of the stirring barrel 1, which provides stable support for the stirring barrel 1, prevents displacement or dumping phenomenon caused by vibration during stirring.
[0035] Further, the liquid level meter 6 is installed on the outer wall of the stirring barrel 1. The operator can monitor the liquid level in the stirring barrel 1 in real time, which provides an important basis for the control of the stirring process. By observing the indication of the liquid level meter 6, the operator can timely adjust the feeding amount, stirring speed and other parameters, to ensure the smooth progress of the stirring process and the high quality mixing of the material.
[0036] The internal flexible stirring device of the filling stirring barrel in the utility model is used, first, the driving motor 72 in the driving control device 7 is started. The driving motor 72 transmits power to the connecting shaft 73 through the bottom output shaft. The connecting shaft 73 starts to rotate under the driving of the power, and realizes the vertical sliding fit through the bottom end sliding groove 75 and the top end of the sliding rod 84, so as to stably transmit the power to the rotating connecting device 8.
[0037] The rotating shaft 83 in the rotating connecting device 8 starts to rotate after receiving power. At the same time, due to the sliding fit between the sliding rod 84 and the connecting shaft 73, the rotating shaft 83 also allows a certain axial sliding during rotation. The connecting column 85 connected outside the sliding rod 84 slides in the reciprocating screw groove 86 inside the supporting protective cylinder 81, so that the sliding rod 84 (and the rotating shaft 83 fixed thereto) also reciprocates along the track of the reciprocating screw groove 86 while rotating.
[0038] The rotation and reciprocation of the rotating shaft 83 are transmitted to the rotating chain 11 through the connecting frame 9. The pin shaft 10 in the connecting frame 9 is hinged with the rotating chain 11, so that the rotating chain 11 can swing flexibly during stirring. This swing, combined with the rotation and reciprocation of the rotating shaft 83, forms a full-range, multi-angle stirring of the material in the stirring barrel 1, effectively avoiding stirring dead angles and improving the uniformity and efficiency of stirring.
[0039] During stirring, material can be added to the stirring barrel 1 through the feed hopper 2 or the charging hole 3 at the top of the stirring barrel 1. When stirring is completed, the discharge pipe 4 at the bottom of the stirring barrel 1 is opened, and the stirred material can be smoothly discharged through the discharge pipe 4.
[0040] The liquid level meter 6 installed on the outer wall of the stirring barrel 1 can monitor the liquid level in the stirring barrel 1 in real time, providing important information for the operator. The operator can adjust the feeding amount, stirring speed and other parameters in a timely manner according to the indication of the liquid level meter 6, to ensure the smooth progress of the stirring process and the high-quality mixing of the material. The rotating sealing sleeve 82 installed between the inner wall of the bottom of the supporting protective cylinder 81 and the outer wall of the rotating shaft 83 effectively prevents leakage of the material during stirring, ensuring the cleanliness and stirring effect in the stirring barrel 1. The supporting feet 5 outside the bottom of the stirring barrel 1 provide stable support for the stirring barrel 1, preventing displacement or tilting due to vibration during stirring.
