Description

Technical Field

[0001] The utility model relates to the technical field of carbonization chamber pressure regulating equipment, and more specifically, to a coke oven rotary curved surface monotonic valve for regulating the pressure of a carbonization chamber. Background Art

[0002] Regardless of whether it is a small, medium or large coke oven, its production process is always accompanied by the raw gas continuously generated in the carbonization chamber overflowing outward, entering the bridge pipe through the riser, and entering the coke oven gas collecting pipe after being cooled by the low-pressure ammonia water spray in the bridge pipe, and then transported to the subsequent gas purification system through the fan. In this process, it is necessary to control the pressure stability of the coke oven carbonization chamber through a monotonic valve and prevent the unorganized overflow of the raw gas from the coke oven. The connection method between the monotonic valve and the bridge pipe and the gas collecting pipe generally adopts a socket structure, that is, an upper socket structure and a lower socket structure are respectively set at the top and bottom of the outer cylinder of the monotonic valve, which are used to connect with the bridge pipe and the gas collecting pipe respectively; the upper socket structure and the lower socket structure are generally designed separately and then connected to the monotonic valve. This monotonic valve has a complex structure during the design and manufacturing process, which will increase the production cost during the mass manufacturing process. In addition, the upper and lower socket structures added separately make the overall weight of the monotonic valve high, which is not conducive to the optimization and transformation of the project.

[0021] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement it according to the description.

[0022] It should be noted that, in the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] like Figure 2 As shown, the corresponding upper spigot structure 14 on the existing monotonic valve 1 is connected to the top of the outer cylinder 12, and then connected to the bridge pipe 2 through the upper spigot structure 14; the lower spigot structure 15 is connected to the bottom of the outer cylinder 12, and then connected to the gas collecting pipe 4 through the lower spigot structure 15. The inner cylinder 11 and the outer cylinder 12 are connected as a whole through the top, and the inner cylinder 11 has upper and lower openings, respectively allowing the raw gas flowing out of the bridge pipe 2 to flow into and out of the monotonic valve 1. The valve cover 13 is rotatably connected to the outer cylinder 12, and is driven to rotate by the actuator 3 to adjust the staggered area between the valve cover 13 and the bottom end of the inner cylinder 11, thereby adjusting the flow area of ​​the raw gas and realizing the adjustment of the raw gas flow pressure.

[0024] like Figure 1 As shown, the utility model provides a coke oven rotary curved monotonic valve for regulating the pressure of a carbonization chamber, comprising an outer cylinder 12, an inner cylinder 11 arranged in the outer cylinder 12, and a valve cover 13 arranged between the outer cylinder 12 and the inner cylinder 11, the valve cover 13 is rotatably connected to the outer cylinder 12 and partially or completely covers the bottom opening of the inner cylinder 11 by rotation, the inner cylinder 11 extends upward to protrude from the outer cylinder 12, an annular disk 16 is fixedly provided on the outer periphery of the inner cylinder 11, a sleeve 17 is fixedly provided thereon, an annular space is formed between the sleeve 17 and the inner cylinder 11 for matching and connecting a bridge pipe 2, the annular disk 16 is sealingly connected to the top end of the outer cylinder 12, a sinking socket is formed at the bottom end of the outer cylinder 12, which is matched and connected to the gas collecting pipe 4.

[0025] The present application combines the upper sinking structure with the inner cylinder 11 into an integrated structure, and directly simplifies the lower sinking structure to the lower edge of the outer cylinder 12. This simplification of parts can reduce some processes and reduce processing. The annular disk 16 is detachably connected to the top of the outer cylinder 12 by bolts 18. A sealing gasket is provided between the annular disk 16 and the top of the outer cylinder 12 to achieve sealing. The valve cover 13 is a U-shaped structure, and its bottom surface contacts and rotates with the bottom end of the inner cylinder 11. The two ends of the valve cover 13 are respectively fixedly connected to the connecting shafts 19 on the opposite sides of the outer cylinder 12, for example, connected by bolts 18. The connecting shaft 19 is driven to rotate by the actuator 3, thereby driving the valve cover 13 to rotate.

[0026] like Figure 4 As shown, the cylinder seat and other structures of the existing actuator 3 are complicated, and the counterweight block 32 is directly fixed and welded on the driving handle 31, which is inconvenient to process.

[0027] like Figure 3 As shown, one side of the connecting shaft 19 is rotatably connected to the outer cylinder 12, and the other side of the connecting shaft 19 is driven to rotate by the actuator 3. The actuator 3 described in the present application includes a driving handle 31 fixedly connected to the connecting shaft 19 and a cylinder 33 connected to one end of the driving handle 31. The driving handle 31 is driven to rotate along the end of the connecting shaft 19 by the extension and contraction of the cylinder 33. A counterweight 32 is provided on the other end of the driving handle 31, and the counterweight 32 is detachably connected to the driving handle 31 by a bolt 18.

[0028] The telescopic rod of the cylinder 33 is hinged to one end of the driving handle 31. The driving handle 31 is V-shaped and can be an integrated structure or a structure composed of two handles. The driving handle 31 is connected to the connecting shaft 19 through the bent portion in the middle thereof. The cylinder 33 is extended and retracted to drive the driving handle 31 to rotate around the end of the connecting shaft 19, and the valve cover 13 is driven to rotate through the connecting shaft 19. The other end of the driving handle 31 opposite to the cylinder 33 is detachably connected to a counterweight 32 through a bolt 18, which is convenient for disassembly and processing.
