Description

Technical Field

[0001] This utility model relates to the field of powdered carbon black storage technology, specifically to a shaft sealing device for an agitator in a powdered carbon black storage tank. Background Technology

[0002] Storage tanks are essential equipment in the storage and processing of powdered carbon black. These tanks are typically equipped with agitators to agitate the powdered carbon black, ensuring material uniformity and meeting the needs of subsequent production or use. The agitator's proper operation relies on a connecting shaft driving the agitation structure to rotate within the tank. However, there is a potential for material leakage at the connection between the connecting shaft and the mounting base on the top of the storage tank. Because the powdered carbon black is in a dynamic state during agitation, and there is a certain pressure inside the tank, improper sealing between the connecting shaft and the mounting base can easily cause the powdered carbon black material to overflow from the connection. This not only wastes material and increases production costs but also pollutes the environment around the storage tank, affecting the cleanliness and safety of the production site, and may even adversely affect the health of operators.

[0003] Existing sealing devices for storage tank agitator shafts are mostly simple in structure and have limited sealing effect. Some sealing methods use only a single sealing ring, which is prone to wear and aging during long-term use or when dealing with special materials such as powdered carbon black, leading to a decline in sealing performance and an inability to effectively prevent material leakage. Utility Model Content

[0004] The purpose of this invention is to provide a shaft sealing device for an agitator in a powdered carbon black storage tank, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shaft sealing device for an agitator in a powdered carbon black storage tank, comprising a tank body, and further comprising:

[0006] A mounting base is fixedly installed on the top of the tank. A connecting assembly is installed on the mounting base, a connecting shaft is installed in the mounting base, and a sealing assembly for sealing the connection shaft and the mounting base is installed on the connecting assembly.

[0007] A bearing is fixedly installed on the outside of the connecting shaft, and the outer ring of the bearing is fixedly installed inside the mounting base.

[0008] Preferably, the connecting assembly includes a connecting shell that is fixedly mounted on the mounting base by bolts, a sealing ring one and a sealing ring two are installed inside the connecting shell, a receiving cavity is opened inside the connecting shell, and a cap is detachably installed at the end of the connecting shell by bolts.

[0009] Preferably, the connecting shell has a receiving groove 1 and a receiving groove 2 inside to accommodate sealing ring 1 and sealing ring 2.

[0010] Preferably, the connecting shell is threaded with a sealing bolt to seal the oil injection hole.

[0011] Preferably, the sealing assembly includes a sleeve inserted into the connecting shell, with two sealing sleeves fitted on the outer side of the sleeve, and sealing rings fitted on the sealing sleeves.

[0012] Preferably, an mounting sleeve is detachably mounted on the sleeve by bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model's connecting assembly includes a first sealing ring and a second sealing ring, respectively installed in receiving grooves one and two, forming a double seal between the mounting base and the connecting shell, effectively preventing material leakage from the tank at the connection point between the mounting base and the connecting shell. Simultaneously, two rubber sealing sleeves are fitted onto the outer side of the sleeve in the sealing assembly, each with a sealing ring. These two sealing sleeves contact the inner wall of the receiving cavity, forming another layer of sealing between the sleeve and the connecting shell. This multi-layered sealing structure significantly improves the overall sealing performance, effectively preventing powdered carbon black material from overflowing from the connection point between the connecting shaft and the mounting base.
