Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of coke oven production, and in particular relates to a coke oven riser flap locking device. Background Art
[0002] The coke oven riser is a device that connects the gas collecting pipe to the carbonization chamber and serves as a channel for the discharge of raw gas from the coke oven. Raw gas refers to untreated coke oven gas that cannot be discharged directly and must be treated through the chemical production system. A flap is installed at the valve body where the coke oven riser is connected to the coke oven riser. When the flap is open, the raw gas enters the gas collecting pipe through the riser. When the flap is closed, the raw gas cannot enter the gas collecting pipe through the riser or enter the riser through the gas collecting pipe. When pushing coke in the coke oven, the riser flap needs to be closed and the water seal cover opened to prevent the raw gas inside the gas collecting pipe from overflowing through the riser.
[0003] At present, in the daily production process of coke ovens, due to the long use time of the riser flaps, the fixing rods of some riser flaps are loose and not closed tightly, which will cause the riser flaps to open slowly after closing, which can easily cause untreated raw gas to overflow from the riser, thereby causing environmental pollution. At the same time, it is easy to burn the workers during the manual re-closing process, posing a great safety risk. Utility Model Content
[0004] The utility model provides a coke oven riser flap locking device, which solves the problem of environmental pollution caused by loosening of fixing rods of the riser flap and loose closure.
[0005] The technical solution of the utility model is: a coke oven riser flap locking device, characterized in that: it includes a shell, a connecting rod and a locking ring, a fixing rod is installed on the shell, the connecting rod is detachably connected to the fixing rod, the other end of the connecting rod is connected to the locking ring, a fixed connecting rod is installed on the flap pull rod of the coke oven riser flap, and the locking ring can be clamped on the fixed connecting rod.
[0006] As a further improvement of the present invention, a connecting hole is provided at the center of the fixing rod, and the connecting rod is clamped in the connecting hole to lock the rising tube flap.
[0007] As a further improvement of the present invention, connecting grooves are provided on both sides of the inner wall of the open end of the shell, and a safety baffle is installed between the two connecting grooves. The safety baffle is provided with an opening, and the connecting rod passes through the opening. The safety baffle is away from the fixed rod, so that the range in which the connecting rod can swing up and down can be reduced, so as to lock the coke oven riser flap.
[0008] As a further improvement of the present invention, a gas detector is installed at the open end of the shell to facilitate constant monitoring of whether there is any leakage of raw gas.
[0009] The beneficial effects of the present invention are as follows: the present invention locks the riser flap on the coke oven riser through the cooperation of the locking ring and the fixing rod, which can effectively prevent the flap from opening automatically and leaking untreated raw gas; at the same time, a gas detector is installed near the flap to facilitate constant monitoring of the working condition of the device. When raw gas leaks, the gas detector will alarm in time, making it convenient for the staff to make timely adjustments, and the sensitivity of the locking mechanism can be adjusted by adjusting the position of the safety baffle on the mounting groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2 It is a side view of the utility model.
[0012] In the figure: 1-shell, 2-connecting rod, 3-fixing rod, 4-safety baffle, 5-locking ring, 6-fixing connecting rod, 7-rising pipe flap pull rod, 8-mounting slot, 9-gas detector. DETAILED DESCRIPTION
[0013] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.
[0014] like Figure 1-2 As shown, a coke oven riser flap locking device is characterized in that it includes a shell 1, a connecting rod 2 and a locking ring 5, a fixing rod 3 is installed on the shell 1, the connecting rod 2 is detachably connected to the fixing rod 3, the other end of the connecting rod 2 is connected to the locking ring 5, a fixed connecting rod 6 is installed on the flap pull rod 7 of the coke oven riser flap, and the locking ring 5 can be clamped on the fixed connecting rod 6.
[0015] A connecting hole is provided at the center of the fixing rod 3, and the connecting rod 2 is clamped in the connecting hole.
[0016] Connecting grooves 8 are provided on both sides of the inner wall of the open end of the shell 1, and a safety baffle 4 is installed between the two connecting grooves 8. The safety baffle 4 is provided with an opening, and the connecting rod 2 passes through the opening. The safety baffle 4 is away from the fixed rod 3, which can reduce the range of the connecting rod 2 that can swing up and down, and is used to lock the rising pipe flap.
[0017] A gas detector 9 is installed at the open end of the shell 1 to monitor whether there is any leakage of raw gas at any time.
[0018] When in use, the shell 1 is fixedly installed on the riser steel structure and positioned opposite to the riser flap pull rod 7. The fixed connecting rod 6 is welded to the appropriate position of the riser flap pull rod 7. According to the installation distance, the connecting rod 2 of appropriate length is selected, and the connecting rod 2 is passed through the opening on the safety baffle 4. The front end of the connecting rod 2 is clamped into the connecting hole of the fixed rod 3. Finally, the locking ring 5 is connected to the end of the connecting rod 2. When closing the riser flap, pull down the riser flap to make the safety baffle 4 away from the fixed rod 3, and put the fixed connecting rod 6 on the riser flap pull rod 7 into the locking ring 5. Adjust the safety baffle 4 to the farthest end to reduce the range in which the connecting rod 2 can swing up and down, so as to achieve the effect of locking the coke oven riser flap. At this time, check whether there is any raw gas leakage through the gas detector 9. If there is leakage, it needs to be opened and the device reconnected. When the riser flap needs to be opened, move the safety baffle 4 close to the fixed rod 3 to the extreme position, remove the fixed connecting rod 6 of the riser flap pull rod 7 from the locking ring 5, and push the riser flap pull rod 7 to open the riser flap.
