Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of stirring devices, in particular to a kind of full-sealed magnetic suspension side stirring device. BACKGROUND

[0002] The stirring device is a kind of equipment for mixing, preparing and conveying various materials with different properties, and its core working principle is to make the materials fully mixed and uniformly distributed in the stirring container through the rotation or reciprocating motion of the stirrer. Among them, the side-entering stirring device (also known as side-entering stirrer) is a stirrer installed on the side wall of the equipment cylinder.

[0003] The existing side-entering stirring device includes a rack, a driving source fixedly installed on the rack, a stirring shaft, and a magnetic coupler connecting the stirring shaft and the driving source. The size of the driving source depends on the output power required by the stirring device. Generally, the larger the output power, the larger the size of the driving source. However, due to the installation structure of the rack fixed to the cylinder and the installation structure of the driving source fixed to the rack, the installation direction of the driving source cannot be adjusted according to the actual use environment and conditions to reduce the interference between the driving source and the worker's activity space or other external equipment. Therefore, the present improvement is born to solve the above problems. SUMMARY

[0004] The purpose of the present utility model is to provide a full-sealed magnetic suspension side stirring device that can change the installation direction of the driving source to improve the installation flexibility and adaptability to the use environment of the device.

[0005] The above technical purpose of the present utility model is achieved by the following technical solution: a full-sealed magnetic suspension side stirring device includes a rack, a driving source installed on the rack, a stirring shaft, and a magnetic coupler connecting the stirring shaft and the driving source. A rotating structure is provided between the driving source and the rack to allow the driving source and the rack to rotate around the output shaft center of the driving source. A locking assembly is provided between the driving source and the rack to limit the rotation of the driving source and the rack. The locking assembly has a locking state and a non-locking state. A control assembly is provided on the rack to control the switching of the locking assembly between the locking state and the non-locking state.

[0006] By adopting the above technical solution, after the rack is fixedly installed on the side wall of the cylinder, the locking assembly can be switched from the locking state to the non-locking state by the control assembly according to the use environment and requirements. Then the driving source can be rotated through the rotating structure to adjust the installation direction of the driving source. When adjusted to the appropriate position, the locking assembly can be switched from the non-locking state to the locking state by the control assembly, which can complete the adjustment and later fixation of the driving source direction to improve the installation flexibility and adaptability to the use environment of the device.

[0007] Further, the locking assembly comprises a circular locking disc fixed on the side of the driving source facing the rack and surrounding the center of the output shaft, and a plurality of locking blocks arranged on the side of the rack facing the driving source and corresponding to the rotating path of the locking disc, the locking blocks reciprocate towards the locking disc and can engage with the locking disc.

[0008] By adopting the above technical scheme, the locking blocks engage with the locking disc to form the steering locking of the rack and the driving source, thereby limiting the relative rotation of the two; when the locking blocks are disengaged from the locking disc, the relative rotation of the rack and the driving source can be realized to perform the adjustment operation of the driving source.

[0009] Further, the control assembly comprises a control ring arranged on the outside of the rack, an ejection spring driving the locking blocks away from each other, and a clamping bolt threadedly connected with the rack and used to drive the control ring towards the locking blocks, the control ring and each locking block correspond to each other along the projection path of the output shaft axis, and the control ring is connected with each locking block.

[0010] By adopting the above technical scheme, the ejection spring drives the locking blocks away from each other to realize the unlocking operation of the locking assembly; by rotating the clamping bolt, the control ring is driven to press the ejection spring, and at the same time, the locking blocks are driven towards the locking disc to form the locking operation of the locking assembly.

[0011] Further, the locking disc is embedded in the driving source, and the two sides of the driving source and the rack are attached to each other.

[0012] By adopting the above technical scheme, the above structure can reduce the external leakage of the locking assembly, prolong the service life of the locking assembly, and reduce the probability of particles entering the gap.

[0013] Further, the rotating structure comprises a plurality of adapter blocks fixedly connected with the driving source and distributed around the center of the output shaft, and a rotating groove is formed between the adapter blocks and the driving source for the rotation of the rack.

[0014] By adopting the above technical scheme, the adapter blocks form the rotating groove to realize the circumferential rotation cooperation between the rack and the driving source.

[0015] Further, the flange is integrally arranged on the driving source, and each adapter block is connected with the flange through a bolt.

[0016] By adopting the above technical scheme, the above arrangement has a simple structure and lower processing cost.

[0017] Further, the ejection spring is sleeved on the frame.

[0018] By adopting the technical scheme, the installation position of the ejection spring is better limited.

[0019] To sum up, the utility model has the following beneficial effects: the utility model can change the installation direction of the driving source, thereby improving the installation flexibility of the device and the adaptability of the use environment. BRIEF DESCRIPTION OF DRAWINGS
