Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-4The utility model provides an embodiment: an emergency exhaust device for a kettle body, comprising an exhaust pipe 1, a connecting pipe 3 is threadedly installed on one side of the exhaust pipe 1, an exhaust column 4 is fixedly installed on one side of the connecting pipe 3, an air inlet 102 is provided on one side of the exhaust pipe 1, a cylinder cavity 101 is provided inside the exhaust pipe 1, a protective cover 10 is provided on one side of the cylinder cavity 101, the protective cover 10 comprises a mounting ring 1001 and a protective net 1002, the mounting ring 1001 is fixedly installed on one side of the protective net 1002, and a limiting ring plate 11 is provided inside the cylinder cavity 101 along one side of the protective cover 10.

[0024] When in use, during the exhaust process of the kettle body, the protective net 1002 inside the protective cover 10 can filter the gas discharged from the kettle body, retain the by-product impurities in the gas, and prevent the impurities from adhering to the inside of the exhaust device and causing blockage. When it is necessary to clean the protective net 1002, the connecting tube 3 can be directly unscrewed from the exhaust tube 1, and then the protective cover 10 can be taken out to clean the protective net 1002, which increases the convenience of disassembling and cleaning the protective net 1002 and is beneficial to the stability of the exhaust of the kettle body.

[0025] Furthermore, a conical groove 401 is provided on one side of the interior of the exhaust column 4, and the conical groove 401 is connected to the barrel cavity 101. An exhaust hole 402 is provided on the other side of the interior of the exhaust column 4, and the exhaust hole 402 is connected to the conical groove 401. An exhaust flow channel 403 is provided above the exhaust hole 402 inside the exhaust column 4, and the exhaust flow channel 403 is connected to the exhaust hole 402. An exhaust head 6 is fixedly installed above the exhaust column 4, and the exhaust head 6 is connected to the exhaust flow channel 403. The exhaust head 6 is an exhaust pipe with a dustproof net inside, which is conducive to the discharge of gas inside the kettle body.

[0026] Furthermore, a push block 15 is provided inside the exhaust hole 402. The push block 15 is set to be cylindrical. The push block 15 fits with the exhaust column 4. A compression spring 14 is fixedly installed on one side of the push block 15. A sealing cover 13 is fixedly installed on one side of the compression spring 14. A sealing plug 12 is fixedly installed on one side of the sealing cover 13. The sealing effect of the sealing plug 12 on the exhaust hole 402 can prevent the outflow of gas under normal pressure inside the kettle body. When the air pressure inside the kettle body gradually increases, the pressure of the air pressure can press the compression spring 14 to contract, so that the sealing cover 13 and the sealing plug 12 move. When the pressure inside the kettle body rises to a certain value, the exhaust flow channel 403 will be opened, so that the high-pressure gas inside the kettle body can flow out, which is convenient for automatic emergency exhaust when the pressure inside the kettle body is too high.

[0027] Furthermore, a guide groove 404 is provided inside the exhaust column 4 along the bottom of the exhaust hole 402, and the guide groove 404 is connected to the exhaust hole 402. A guide plate 16 is provided inside the guide groove 404, and the guide plate 16 is fixedly connected to the push block 15. Through the action of the guide groove 404 and the guide plate 16, the linear stability of the movement of the push block 15 is increased.

[0028] Furthermore, a fixed disk 7 is fixedly installed on one end face of the exhaust column 4, and a handwheel 8 is provided on one side of the fixed disk 7. A threaded rod 9 is fixedly installed on the side of the handwheel 8 facing the fixed disk 7. The threaded rod 9 is threadedly connected to the fixed disk 7. One end of the threaded rod 9 passes through the fixed disk 7 and is rotatably connected to the push block 15, so that when the kettle body needs to be directly exhausted in an emergency, the threaded rod 9 is driven to rotate by rotating the handwheel 8, which can push the push block 15 to move and drive the sealing cover 13 and the sealing plug 12 to move to open the exhaust flow channel 403, so that the gas can be discharged directly.

[0029] Furthermore, a mounting ring plate 2 is fixedly mounted on one end of the outer side of the exhaust pipe 1. A plurality of bolt holes are arranged in a ring shape inside the mounting ring plate 2, so that the exhaust device can be easily mounted on the kettle body.

[0030] Furthermore, a ring sleeve 5 is fixedly mounted on the outer side of the connecting tube 3 , and the outer side of the ring sleeve 5 is roughened, thereby improving the anti-slip property of the rotating connecting tube 3 and increasing the practicality.

[0031] Working principle: When in use, the exhaust device is installed on the exhaust port of the kettle body by installing the ring plate 2. The sealing effect of the sealing plug 12 on the exhaust hole 402 can prevent the outflow of gas under normal pressure inside the kettle body, and when the air pressure inside the kettle body gradually increases, the pressure of the air pressure can press the compression spring 14 to contract, so that the sealing cover 13 and the sealing plug 12 move. When the pressure inside the kettle body rises to a certain value, the exhaust flow channel 403 will be opened to allow the high-pressure gas inside the kettle body to flow out, which is convenient for automatic emergency exhaust when the internal pressure of the kettle body is too high. When the kettle body needs to be directly exhausted in an emergency, the hand wheel 8 is turned to drive the exhaust port 403 to open. The threaded rod 9 rotates, which can push the push block 15 to move and drive the sealing cover 13 and the sealing plug 12 to move to open the exhaust flow channel 403, so that the gas can be discharged directly. At the same time, during the exhaust process of the kettle body, the protective net 1002 inside the protective cover 10 can filter the gas discharged from the kettle body, retain the by-product impurities in the gas, and prevent the impurities from adhering to the inside of the exhaust device and causing blockage. When it is necessary to clean the protective net 1002, the connecting tube 3 can be directly unscrewed from the exhaust tube 1, and then the protective cover 10 can be taken out to clean the protective net 1002, which increases the convenience of disassembling and cleaning the protective net 1002.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
