Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature gas medium circulation utilization, in particular to a high-temperature gas medium circulation device. Background Art

[0002] Currently, high-temperature gases in the mining, smelting, chemical, petrochemical, and smelting industries, both domestically and internationally, cannot be recycled. The main problem is the lack of circulation equipment capable of operating at temperatures between 200°C and 500°C and at high pressure (6MPa). This prevents the full recycling of heat energy, making some operating conditions requiring high-temperature, high-pressure gases impossible. Existing gas compressors operate at temperatures below 60°C. To meet the demands of productivity growth and the requirements of the electromagnetically heated carbon dioxide gas vulcanization molding process for rubber tires, a high-temperature gas circulation device has been developed and designed.

An intake valve core 7 and an exhaust valve core 8 are provided at the upper end of the cylinder body 6, and the intake valve core 7 and the exhaust valve core 8 are transmission-connected to the camshaft 10, and the camshaft 10 is transmission-connected to the crankshaft 3.

[0024] The working principle and beneficial effects of the above scheme are as follows:

[0025] The present application is connected to the camshaft 10 through the crankshaft 3, so that the intake valve core 7 and the exhaust valve core 8 connected to the camshaft 10 can be opened and closed with the rotation of the crankshaft 3, that is, opened and closed with the reciprocating movement of the piston 5 in the cylinder body 6. Compared with the structure of ordinary valves that are directly opened and closed by the pressure in the cylinder body 6, so that its operating temperature cannot exceed 60°C, the present application changes the driving mode of opening and closing of the intake valve core 7 and the exhaust valve core 8, so that it can adapt to the compression process of high-temperature gas, and can better utilize the high-temperature gas generated by mining, chemical industry, petrochemical industry, smelting and other industries.

[0026] Example 2

[0028] The upper end of the intake valve core 7 is fixedly connected to the upper end of the valve push rod 11 , and the lower end of the valve push rod 11 is connected to the camshaft 10 .

[0029] The upper end of the exhaust valve core 8 is fixedly connected to the upper end of the valve push rod 11 , and the lower end of the valve push rod 11 is connected to the camshaft 10 .

[0030] The crankshaft 3 is rotatably connected to the housing 2, and the crankshaft 3 passes through the housing 2. One end of the crankshaft 3 located outside the housing 2 is fixedly connected to a gear 12, and the other end of the crankshaft 3 located outside the housing 2 is fixedly connected to the output end of the motor 1.

[0034] The working principle and beneficial effects of the above scheme:

[0035] The motor 1 drives the crankshaft 3 in the housing 2 to rotate, and the crankshaft 3 drives the connecting rod 4 to drive the piston 5 to reciprocate in the cylinder body 6. When the connecting rod 4 drives the piston 5 to retract, the crankshaft 3 drives the camshaft 10 through the meshing of gear 1 12 and gear 2 13 to control the valve push rod 11 to open the intake valve core 7, and the high-temperature gas enters the cylinder. This is the intake process. When the connecting rod 4 drives the piston 5 to extend, the crankshaft 3 drives the camshaft 10 through the meshing of gear 1 12 and gear 2 13 to control the valve push rod 11 to close the cylinder intake valve core 7, and the gas When the gas is compressed in the cylinder body 6 and extends to the bottom, the camshaft 10 controls the valve push rod 11 to open the cylinder exhaust valve core 8, and the compressed high-temperature and high-pressure gas is discharged. This is the exhaust process. The opening and closing of the exhaust valve is controlled by the crankshaft 3 driving the camshaft 10 to move, and the camshaft 10 drives the valve push rod 11 to make reciprocating linear motion to control the opening and closing of the valve core, rather than the valve controlling the opening and closing of the valve; it can adapt to the compression process of high-temperature gas and can better utilize the high-temperature gas generated in the mining, smelting, chemical, petrochemical and smelting industries.
