Description

Technical Field

[0001] The utility model relates to the technical field of chemical engineering, and relates to a surfactant emulsifying device. Background Art

[0002] Non-ionic surfactants have good hard water resistance and the characteristic of low foaming property, so they are suitable as special detergents. Because they have various properties such as dispersion, emulsification, foaming, wetting, and solubilization, they have important uses in many fields. Emulsification is a process in which a liquid is evenly dispersed in another immiscible liquid in the form of extremely tiny droplets. Emulsification is a liquid-liquid interface phenomenon. For two immiscible liquids, such as oil and water, they are separated into two layers in a container. The oil with a lower density is on the upper layer, and the water with a higher density is on the lower layer. If an appropriate surfactant is added and stirred strongly, the oil is dispersed in the water to form an emulsion, and this process is called emulsification.

[0003] However, most of the existing emulsifying devices use ordinary mechanical seals inside. The installation is very inconvenient and a large number of support springs are directly exposed inside, and it is easy for materials to accumulate on them and difficult to clean.

[0004] In summary, in order to solve the deficiencies in the prior art, it is necessary to design a surfactant emulsifying device with a simple structure and easy to clean. Content of the Utility Model

[0005] The utility model provides a surfactant emulsifying device to solve the problems of the prior art.

[0006] The purpose of the utility model can be achieved by the following technical solutions: A surfactant emulsifying device includes: an emulsifying machine tank body and an upper flange, a lower flange, an upper sealing assembly and a lower sealing assembly arranged on the emulsifying machine tank body. The upper flange is bolted to the upper cover of the emulsifying machine tank body. The upper flange is connected with a connecting shaft, the lower end of the connecting shaft is connected to the lower flange, a stirring shaft is connected below the lower flange. Both the upper sealing assembly and the lower sealing assembly include a shaft sleeve, a sealing sleeve and an outer sealing ring. The shaft sleeve of the upper sealing assembly is sleeved on the connecting shaft, and the shaft sleeve of the lower sealing assembly is sleeved on the stirring shaft. The sealing sleeve is threadedly connected to the outer end of the shaft sleeve. The sealing sleeve of the upper sealing assembly is threadedly connected to the upper flange and a first clamping cavity is provided at the connection. The sealing sleeve of the lower sealing assembly is threadedly connected to the lower flange and a second clamping cavity is provided at the connection. The outer sealing ring includes an upper outer sealing ring and a lower outer sealing ring. The upper outer sealing ring is clamped in the first clamping cavity, and the lower outer sealing ring is clamped in the second clamping cavity.

[0007] Further improvement, a fastening bolt connected to the shaft sleeve is provided at the inner side end of the sealing sleeve, and a sealing cover is provided outside the fastening bolt.

[0008] For further improvement, rubber gaskets are provided at the connection between the sealing sleeve of the upper sealing assembly and the end face of the upper flange, and at the connection between the sealing sleeve of the lower sealing assembly and the end face of the lower flange.

[0009] For further improvement, inner sealing rings are provided on the inner side of the shaft sleeve of the upper sealing assembly sleeved on the connecting shaft and on the inner side of the shaft sleeve of the lower sealing assembly sleeved on the stirring shaft.

[0010] Compared with the prior art, the beneficial effects of the surfactant emulsifying device of the present utility model are as follows:

[0011] The shaft sleeve, sealing sleeve and outer sealing ring in the upper sealing assembly are cooperatively installed on the connecting shaft and locked to the upper flange with bolts, enabling the stirring rod connected to the lower end of the upper flange to rotate and stir the material. The shaft sleeve, sealing sleeve and outer sealing ring in the lower sealing assembly are cooperatively installed on the connecting shaft and installed on the stirring shaft and locked to the lower flange with bolts, enabling the stirring rod connected to the upper end of the lower flange to rotate and stir the material. The stepped shaft sleeve and the sealing sleeve are more tightly cooperatively sleeved. The outer sealing ring is snap-fitted in the cap-shaped cavity between the sealing sleeve and the flange, which can prevent liquid from seeping in and improve the sealing performance. Compared with the existing mechanical seal, the upper sealing assembly and the lower sealing assembly omit the support spring structure, ensuring that there are no components exposed to the outside inside the container, preventing the accumulation of materials on connection structures such as springs, and facilitating cleaning.
