Embodiment Construction

[0011] Below in conjunction with drawing, the present invention is described in detail:

[0012] As shown in the accompanying drawings, in the figure: 1, the middle hollow shaft, 2, the groove, 3, the cover plate, 4, the hinge, 5, the sealing water layer. It includes an intermediate hollow shaft that can go deep into the airflow channel inside the boiler body, a groove that surrounds the upper end of the intermediate hollow shaft, and its connection with the intermediate hollow shaft is a seamless and fixed connection, and covers the upper end surface of the intermediate hollow shaft. Cover with raised edges. A rock wool sealing ring to prevent gas leakage is provided at the contact between the cover plate and the upper end surface of the intermediate hollow shaft. A hinge connected with the boiler body is arranged on the cover plate to prevent the cover plate from flying away and hurting people when an explosion occurs.

[0013] The above-mentioned embodiments are only one ...

Abstract

The invention discloses an explosion-proof device for a boiler and relates to the technical field of boiler machinery manufacturing. It includes an intermediate hollow shaft that can go deep into the airflow channel inside the boiler body, a groove that surrounds the upper end of the intermediate hollow shaft, and its connection with the intermediate hollow shaft is a seamless and fixed connection, and covers the upper end surface of the intermediate hollow shaft. Cover with raised edges. Due to the adoption of the above structure, the present invention has the advantages of simple structure, low cost and good explosion-proof effect.

Description

[0001] technical field [0002] The invention relates to the technical field of boiler machinery manufacturing, in particular to an explosion-proof device used on a boiler. Background technique [0003] Hot water boilers are widely used in the prior art. Explosions often occur due to various reasons during use, which may damage the main body of the boiler, cause personal casualties, and easily cause large economic losses. In particular, boilers using gas generators are more prone to explosions due to gas ignition. In the prior art, there is no explosion-proof device for boilers with simple structure and good explosion-proof effect. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an explosion-proof device for boilers with simple structure and good explosion-proof effect. [0005] The explosion-proof device for the boiler of the present invention comprises a middle hollow shaft which can g...
