[0002] The cooling structure of the original sealing device for the kettle is that the cooling water inlet, the cooling ring groove and the cooling water outlet are formed on the sealing box. This cooling structure cannot directly cool the static ring, while the mechanical sealing device for the contact type kettle The friction between the static ring and the moving ring generates a lot of heat. The original cooling structure can only cool the static ring and the moving ring through the heat transfer principle through the medium, and the cooling effect is not good.

Embodiment
[0010] Embodiment: An improved cooling structure of a contact air-lubricated kettle mechanical seal device, including a static ring seat 1 at the atmospheric end, a static ring seat 2 at the medium end, and a sealing box 3, and the static ring 4 at the medium end is fixed on the static ring seat at the medium end On the ring seat 2, a cooling groove ring 6 is formed in the sealing box 3, and a cooling water outlet 8 is provided on the outer wall of the sealing box 3, and the cooling water inlet 7 and the cooling water outlet 8 are respectively connected to the cooling groove ring 6 and the outside world. A cooling cycle is formed. Based on the direction of use, an annular groove 9 is provided on the outer peripheral surface of the static ring 4 at the medium end. The water inlet 7 flows into the cooling groove ring 6 and the annular groove 9, and then flows out from the cooling water outlet 8. The cooling water in the annular groove 9 directly acts on the outer peripheral facad...

The invention discloses an improved cooling structure of a mechanical sealing device for a contact type air lubrication kettle, comprising an air end fixing ring base, a medium end fixing ring base and a sealing box body, a medium end fixing ring is fixed on the medium end fixing ring base, a cooling grooved ring is formed in the sealing box body, a cooling water outlet is arranged on the outer wall of the sealing box body, a cooling water inlet and the cooling water outlet are respectively communicated with the cooling grooved ring and the outside, so as to form cooling circulation; by taking using direction as criteria, a ring-shaped groove is arranged outside the peripheral vertical surface of the medium end fixing ring, the ring-shaped groove is communicated with the peripheral vertical surface of the medium end fixing ring and a cooling grooved ring in a sealing way, in the way, cooling water flows in the cooling grooved ring and the ring-shaped groove from the cooling water inlet and flows out from the cooling water outlet, cooling water in the ring-shaped groove acts on the peripheral vertical surface of the medium end fixing ring directly, so as to directly cool the medium end fixing ring part, reduce heat generated by friction of the medium end fixing ring and a medium end moving ring to the maximum extent and obtain optimal running environment of the mechanical sealing device for the kettle.
Description
technical field [0001] The invention relates to a mechanical seal device for a kettle, in particular to an improved cooling structure of a contact air-lubricated mechanical seal device for a kettle. Background technique [0002] The cooling structure of the original sealing device for the kettle is that the cooling water inlet, the cooling ring groove and the cooling water outlet are formed on the sealing box. This cooling structure cannot directly cool the static ring, while the mechanical sealing device for the contact type kettle The friction between the static ring and the moving ring generates a lot of heat. The original cooling structure can only cool the static ring and the moving ring through the principle of heat transfer through the medium, and the cooling effect is not good. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides an improved cooling structure of a contact air-lubricated mechanical seal de...
