Description

Technical Field

[0001] The utility model relates to an anti - falling device for the stirring shaft of a tank body, belonging to the technical field of tank body stirring equipment in industries such as chemical industry, food, and medicine. Background Technique

[0002] In industries such as chemical industry, food, and medicine, tank body stirring equipment is widely used in the mixing, stirring, and reaction of various materials. The stirring shaft is the core component of the tank body stirring equipment, and its stable operation directly affects the production efficiency and product quality. However, during the operation of the equipment, due to various reasons, such as equipment aging, improper maintenance, and operation errors, the stirring shaft may fall off and fall into the stirring tank body, resulting in equipment shutdown and even potential safety accidents. In addition, after the stirring shaft falls into the stirring tank body, it is necessary to open the upper cover of the stirring tank to fix the stirring shaft and then lift it to the initial position. During the processing, due to a large amount of sulfur foam in the tank body, irritating and toxic gases are generated, and maintenance personnel cannot work for a long time, requiring maintenance personnel to work alternately, resulting in a long maintenance time. Therefore, how to prevent the stirring shaft from falling off and improve the operation stability of the equipment has been a concern in the industry. Content of the Utility Model

[0003] The purpose of the utility model is to provide an anti - falling device for the stirring shaft of a tank body, which can prevent the stirring shaft of the tank body from falling into the stirring tank body and solve the problems existing in the background technique.

[0004] The technical solution of the utility model is as follows:

[0005] An anti - falling device for the stirring shaft of a tank body includes a motor, a speed reducer, a coupling, a frame, an anti - falling clamping plate, a stirring shaft, an impeller, a key, a bearing seat, and a tank body. The frame and the bearing seat are respectively fixed on the upper surface of the tank body. The motor and the speed reducer are fixed on the frame. The output shaft of the speed reducer is connected to the stirring shaft through the coupling and the key. The stirring shaft is rotatably connected to the bearing seat. The anti - falling clamping plate is fixed on the stirring shaft between the coupling and the bearing seat.

[0006] The anti - falling clamping plate is fixed on the stirring shaft between the coupling and the bearing seat through fixing bolts.

[0007] There are two anti - falling clamping plates, and the two anti - falling clamping plates are respectively fixed on the stirring shaft between the coupling and the bearing seat through fixing bolts.

[0008] The two anti - falling clamping plates are evenly arranged along the circumferential direction of the stirring shaft.

[0009] The surfaces of the two anti - falling clamping plates in contact with the stirring shaft are arc surfaces that fit the stirring shaft.

[0010] The beneficial effects of the utility model are as follows: it can prevent the mixing shaft from falling off and dropping into the mixing tank body, with a simple structure, convenient operation and replacement. BRIEF DESCRIPTION OF THE DRAWINGS
