Description

Technical Field

[0001] The utility model relates to the technical field of discharge pipes, in particular to a spring protection device for a discharge pipe. Background Art

[0002] During the unloading process of liquid caprolactam, a metal hose needs to be connected to the tank truck to transport the liquid caprolactam to the tank area. The original metal hose is directly connected to the flange and buckle, and needs to be bent to be connected to the tank truck discharge port and disassembled. As a result, the metal hose is prone to damage and leakage at the bending point, thereby increasing the fire safety hazard and environmental pollution caused by raw material leakage. In addition, the service life of a general metal hose is about one month, so a spring protection device for a discharge pipe is proposed. Utility Model Content

[0003] 1. Technical issues to be resolved

[0004] In view of the deficiencies in the prior art, the utility model provides a spring protection device for a discharge pipe, which solves the problems raised in the above-mentioned background technology.

[0005] (II) Technical solution

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a spring protection device for a discharge pipe, comprising a discharge pipe, a card sleeve joint is installed at one end of the discharge pipe, a spring protection structure A connected to the card sleeve joint is provided on the discharge pipe, a flange is installed at the other end of the discharge pipe, and a spring protection structure B connected to the flange is provided on the discharge pipe.

[0007] Furthermore, the spring protection structure A comprises a steel wire spring, and the steel wire spring is arranged at one end of the discharge pipe.

[0008] Furthermore, the length of the steel wire spring is 400 mm, and the inner diameter of the steel wire spring is 100 mm.

[0009] Furthermore, the structure of the spring protection structure A is the same as that of the spring protection structure B but their installation positions are different.

[0010] Furthermore, one end of the discharge pipe is connected to the filter via a flange, and a valve is provided between the flange and the filter.

[0011] Furthermore, the ferrule joint is a C1 type ferrule joint.

[0012] Compared with the prior art, the spring protection device for the discharge pipe is equipped with spring protection structures between the discharge pipe and the ferrule joint and between the discharge pipe and the flange, respectively, so that the spring protection structure can protect the metal discharge pipe, making it difficult for the metal discharge pipe to be excessively bent during the bending process, and the bending degrees of various parts are kept consistent, thereby increasing the service life of the easily bent parts to about 5 months and reducing the safety and environmental hazards.
