Description

Technical Field

[0001] The present application relates to the technical field of explosion-proof of tempering furnaces, and in particular to an explosion-proof cover of a tempering furnace. Background Art

[0002] During the operation of the tempering furnace, especially under high temperature heating conditions, the pressure inside the furnace may increase sharply due to various reasons (such as gas expansion inside the furnace, thermal expansion and contraction of furnace wall materials, heat release of material reactions, etc.), which may cause the furnace to explode in severe cases, resulting in major safety accidents such as casualties, equipment damage and production interruption. Therefore, ensuring the safe operation of the tempering furnace, especially effectively preventing the risk of explosion caused by abnormal increase in furnace pressure, has become a core issue in the design and use of the tempering furnace.

[0003] Existing tempering furnace explosion-proof measures mostly use explosion-proof covers for pressure control. The traditional explosion-proof cover design usually includes a cover body fixedly installed on the furnace mouth, which is opened and closed manually or electrically to adjust the pressure in the furnace; the traditional explosion-proof cover and the furnace mouth are often not tightly matched, and the sealing effect is poor. When the pressure in the furnace rises suddenly, opening the explosion-proof cover manually or electrically often has a delayed response and cannot release the excess pressure in time, resulting in safety hazards. Summary of the invention

[0010] Compared with the prior art: the present application achieves significant improvement in explosion-proof performance and automatic pressure relief function, providing a strong guarantee for the safe and efficient operation of the tempering furnace. The circular hole arranged on the upper surface of the explosion-proof cover serves as a pressure relief channel, which can automatically release the pressure in the furnace.

[0014] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application (for the convenience of description and understanding, the following is Figure 2 All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0015] See also Figure 1-2 The present application provides a technical solution: an explosion-proof cover of a tempering furnace, comprising a waste cover assembly 5, wherein an adjustable pressure seat is provided at the lower outlet of the waste cover assembly 5.

[0016] The waste cover assembly 5 is a component of the tempering furnace explosion-proof cover system, and the adjustment pressure seat arranged at the outlet below it plays an explosion-proof function.

[0017] The regulating pressure seat includes an explosion-proof cover seat 7, an explosion-proof cover 6, a first screw rod 11, a connecting support plate 1, a lever 2 and a lever bracket 8. The explosion-proof cover 6 is arranged inside the spherical cavity of the explosion-proof cover seat 7. The explosion-proof cover 6 and the explosion-proof cover seat 7 are coaxially arranged. The upper surface of the explosion-proof cover 6 is provided with a connecting support plate 1. The connecting support plate 1, the explosion-proof cover 6 and the explosion-proof cover seat 7 are connected by the first screw rod 11. The upper end of the connecting support plate 1 is horizontally connected to the lever 2, and the lever 2 is hinged to the lever bracket 8.

[0018] The explosion-proof cover seat 7 adopts a quasi-spherical concave cavity design, and the explosion-proof cover 6 is installed inside; this structure ensures that the explosion-proof cover 6 and the explosion-proof cover seat 7 can be tightly fitted, effectively improving the sealing performance and preventing the high-pressure gas in the furnace from escaping. It is coaxially arranged with the explosion-proof cover 6, which is conducive to maintaining the parallelism between the two and ensuring the smoothness and stability of the opening and closing process.

[0019] The explosion-proof cover 6 is located inside the explosion-proof cover seat 7 and is a component that directly closes the tempering furnace opening. The connecting support plate 1 provided on the upper surface of the explosion-proof cover 6 enables the explosion-proof cover 6 to be effectively linked with other components of the adjustment pressure seat to achieve the opening and closing control of the explosion-proof cover 6.

[0020] One end of the lever 2 is hinged to the connecting support plate 1, and the other end is usually counterweighted or provided with a weight 4. By utilizing the lever principle, the force applied to the explosion-proof cover 6 by steam is used to make the lever 2 swing, and under the action of the weight 4, the steam is released, which effectively prevents the explosion.

[0021] The lever bracket 8 provides a reliable support and hinge point for the lever 2, ensuring that the lever 2 can remain stable during operation.

[0022] The outer circumference of the explosion-proof cover seat 7 is arranged with adapter ears, and threaded holes are arranged in the adapter ears. The threaded holes are correspondingly connected with second screw rods 10, and the second screw rod 10 is connected to the three-claw bracket 3 arranged on the upper surface of the explosion-proof cover seat 7.

[0023] The adapter ears on the outer circumference of the explosion-proof cover seat 7 and its internal threaded holes, as well as the corresponding second screw rod 10 and three-claw bracket 3, and the height of the three-claw bracket 3 are adjusted by the second screw rod 10, forming an auxiliary device for adjusting the three-claw bracket 3, thereby improving the convenience of use.

[0024] Furthermore, a circular hole is provided on the upper surface of the explosion-proof cover 6 .

[0025] The circular hole on the explosion-proof cover 6 is a pressure relief channel for releasing the pressure exceeding the pressure in the furnace.

[0026] Furthermore, a triangular protrusion is provided at the upper end of the explosion-proof cover seat 7 , and a corresponding groove is provided inside the explosion-proof cover 6 .

[0027] The cooperation of the triangular protrusion and the groove forms a unique positioning structure; when the explosion-proof cover 6 is placed on the explosion-proof cover seat 7, the triangular protrusion will be embedded in the groove, ensuring the coaxiality and verticality between the explosion-proof cover 6 and the explosion-proof cover seat 7, avoiding poor sealing or difficulty in opening and closing due to installation deviation; simplifying the installation process of the explosion-proof cover 6, ensuring good sealing performance of the explosion-proof cover 6 in the closed state.

[0028] Furthermore, a wire seat 9 is provided at the lower end of the second wire rod 10 .

[0029] The wire seat 9 provided at the lower end of the second screw rod 10 is used to adjust the position of the second screw rod 10 by rotating the wire seat 9, thereby adjusting the height of the three-claw bracket 3 and adjusting the opening and closing size of the explosion-proof cover 6.

[0030] Furthermore, a weight 4 is provided at the end of the lever 2 .

[0031] Due to the mass of the weight 4 and the setting of the lever arm length, the force exerted on the explosion-proof cover 6 at the other end of the lever is amplified; even if the explosion-proof cover 6 is heavy, when the steam pressure reaches the preset value, the explosion-proof cover 6 is opened under the action of the weight 4 and the steam pressure to perform pressure relief.

[0032] When in use: place the explosion-proof cover 6 in the quasi-spherical cavity of the explosion-proof cover seat 7, ensure that the triangular protrusion is precisely aligned with the groove, install the connecting support plate 1 on the upper surface of the explosion-proof cover 6, and connect it to the explosion-proof cover seat 7 through the first screw rod 11; install the lever 2 to be hinged with the connecting support plate 1, and connect the other end to the weight 4. The lever 2 is firmly hinged with the lever bracket 8. When the steam reaches the set value, the explosion-proof cover 6 is opened and closed under the action of the steam and the weight 4 to release the pressure. When the pressure release is completed, the explosion-proof cover 6 is re-fitted with the explosion-proof cover seat 7 under the action of gravity, effectively preventing the risk of explosion caused by excessive pressure in the furnace, while providing a convenient and accurate explosion-proof cover control function to ensure the safe and stable operation of the tempering furnace.

[0033] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
