Description

Technical Field

[0001] This utility model relates to the field of disassembly device technology, specifically a side-entry stirrer. Background Technology

[0002] In industrial production, agitators are often needed to thoroughly mix liquids in containers or prevent the sedimentation of suspended solids. Currently, the agitator shaft of the side-entry agitator used in the industry is fixedly connected to the reducer via a coupling, and connected to the container via a mechanical seal. The reducer is also connected to the motor drive. When the agitator is being repaired, the reducer and motor need to be removed in order to disassemble the mechanical seal, which is time-consuming, labor-intensive, and results in low equipment maintenance efficiency. Utility Model Content

[0003] The main purpose of this utility model is to provide a side-entry agitator to solve the problem that in the prior art, the mechanical seal of the side-entry agitator needs to be disassembled by removing the reducer and motor during maintenance, which is time-consuming, labor-intensive, and results in low equipment maintenance efficiency.

[0004] To achieve the above objectives, this utility model provides a side-entry stirrer, including a motor, a reducer connected to the motor drive, and a reducer output shaft on the reducer; a stirring shaft is fixedly connected to the reducer output shaft via a coupling, and the stirring shaft is connected to a mounting flange for connection with a container via a mechanical seal; a protective cover is provided between the mounting flange and the reducer; the distance between the reducer output shaft and the stirring shaft is greater than the width of the mechanical seal; and a maintenance hole is provided on the protective cover for removing and replacing the mechanical seal.

[0005] Furthermore, the coupling includes a first flange for connection to the output shaft of the reducer, a second flange for connection to the agitator shaft, and a short section bolted between the first flange and the second flange; the second flange includes two half flanges bolted together.

[0006] Furthermore, a protective mesh is detachably attached to the outside of the maintenance hole.

[0007] Furthermore, the motor is located above the reducer, and the motor and reducer are connected by belt drive; the rear of the motor and reducer are rotatably connected, and the front is connected by an adjustable-length support rod; the top of the support rod is hinged to the motor, and the bottom is hinged to the reducer.

[0008] This invention improves efficiency by making the distance between the reducer output shaft and the agitator shaft greater than the width of the mechanical seal and by providing a maintenance hole, allowing for the disassembly and assembly of the mechanical seal through the maintenance hole. This eliminates the need to disassemble the motor and reducer when maintaining the agitator, resulting in high maintenance efficiency. Attached Figure Description
