Description

Technical Field

[0001] The utility model relates to the technical field of air volume ratio adjustment structures, in particular to a coke oven air volume ratio adjustment structure. Background Art

[0002] Traditional coke ovens have a great impact on the environment. The adjustment of the primary and secondary air inlets of heat recovery coke ovens has a great influence on the output and quality of coke. The air introduced by the primary air inlet on the top of the coke oven burns directly on the top of the carbonization chamber, and the coal cakes are heated by thermal radiation. The adjustment of the secondary air inlet volume should take into account the flame elongation and complete combustion to ensure uniform heating under the coal cakes. The patent with application number 201821168907.9 discloses "an air volume adjustment structure, including a frame and at least one louver, the frame is connected end to end to form a frame, and the louver is placed in the frame, The two ends of the shutter are respectively connected to two opposite frames through a rotating shaft. A handle linked to the rotating shaft is provided on the frame. A connecting hole for the rotating shaft to pass through is provided on the frame. A positioning mechanism is provided between the rotating shaft and the connecting hole. The positioning mechanism includes a plug-in hole provided on the outer peripheral surface of the rotating shaft, an elastic plug-in component provided on the inner wall of the connecting hole, and an adjustment and reset component of the elastic plug-in component. The plug-in hole is provided along the radial direction of the rotating shaft, and the elastic plug-in component and the plug-in hole form a plug-in fit. The above structure provides an air volume adjustment structure with convenient adjustment, simple structure and long service life. ";

[0003] The existing technology only solves the problem that the air intake volume cannot be adjusted, but during use, it is impossible to accurately obtain the current rotation angle of the valve plate. When adjusting again, there may be a large error, resulting in excessive or insufficient air intake, thereby affecting the combustion of coal cakes. In addition, the adjustment process completely relies on manual calculation of the air intake volume to control the size of the valve plate rotation angle. However, when the coal cakes are heated, the internal temperature and pressure will continue to change. Relying on manual adjustment increases the labor intensity of the operators and increases the production cost of coking. Utility Model Content

Since the temperature at the air inlet of the coke oven is relatively high, a heat-resistant protective layer is installed on the outside of the valve shaft 5 through bolts, and the length of the valve shaft 5 can be adjusted as needed.

[0035] Working principle: After collecting the temperature and pressure inside the valve body 1 through the temperature sensor and the pressure sensor, the button control execution box 13 is used to start the cylinder 8, and the push rod 9 pulls the mounting plate downward, and the metal bracket 10 moves downward to drive the movable plate 76 to move downward, so that the connecting rod installed in the middle of the movable plate 76 drives the limit block 74 to move downward, and after the rectangular block in the middle of the limit block 74 is movably connected with the rectangular groove 73 outside the rotating block 72, the motor 710 is started to rotate the second shaft rod in the middle of the motor 710, and the second rotating roller 78 starts to rotate. Since a belt is installed between the first rotating roller 77 and the second rotating roller 78, the first rotating roller 77 will also rotate accordingly, and the connecting rod drives the limit block 74 to rotate, so that the valve shaft 5 at the bottom end of the rotating block 72 rotates and drives the valve plate 3 to rotate. Since the first rotating roller 77 is installed with a first shaft rod at the top, and an indicator rod 79 is installed at the top of the first shaft rod, the first rotating roller 77 rotates and drives the first shaft rod to rotate, so that the indicator rod 79 rotates.
