[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is a double water seal groove furnace mouth sealing device, including a first water seal groove installed at the coke oven mouth and a second water seal groove installed on the hopper, the second water seal groove is installed above the flange plate at the bottom of the hopper, the first water seal groove is provided with a first overflow groove, and the second water seal groove is provided with a second overflow groove. The first overflow groove is used to overflow the water in the first water seal groove into the second water seal groove. The first water seal groove is also installed with a movable sealing ring assembly, and the sealing ring assembly is used to seal the gap between the first water seal groove and the second water seal groove when loading.
[0005] Preferably, the sealing ring assembly includes a movable sealing ring installed on the second water seal groove, the movable sealing ring is arranged on the outside of the outer ring of the second water seal groove, an annular baffle is provided on the inner wall of the top of the movable sealing ring, the annular baffle is clamped on the flange plate at the bottom of the hopper, the bottom of the movable sealing ring is used to be sleeved on the inner ring of the first water seal groove, and the hopper is also equipped with a lifting control mechanism for controlling the lifting and lowering of the movable sealing ring.
[0006] Preferably, the height of the movable sealing ring is the same as the height from the second overflow groove to the bottom of the second water seal groove.
[0007] Preferably, the lifting control mechanism includes a fixed plate installed on the hopper, and lifting control cylinders are installed on both sides of the fixed plate, and the piston rods of the lifting control cylinders are connected to the outer wall of the movable sealing ring.
[0008] Compared with the existing technology, the utility model has the following technical effects: the utility model has a simple structure and a reasonable design, and adopts a double water seal groove structure. When the coke oven is loaded with coke, the first water seal groove is located directly above the second water seal groove, and the first water seal groove and the second water seal groove are sealed by a movable sealing ring, so that the sealing effect is better, the structure is more reliable and stable, and the service life is long. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a structural diagram of the present utility model.
[0010] Figure 2 It is a structural schematic diagram of the movable sealing ring in the utility model. DETAILED DESCRIPTION
[0011] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0012] like Figures 1 to 2 As shown, a double water seal groove furnace mouth sealing device includes a first water seal groove 1 installed at the coke oven mouth and a second water seal groove 2 installed on the hopper 3. The second water seal groove 2 is installed above the flange plate at the bottom of the hopper 3. The first water seal groove 1 is provided with a first overflow groove 4, and the second water seal groove 2 is provided with a second overflow groove 5. The first overflow groove 4 is used to overflow the water in the first water seal groove into the second water seal groove 2. A movable sealing ring assembly is also installed on the first water seal groove 1. The sealing ring assembly is used to seal the gap between the first water seal groove 1 and the second water seal groove 2 when loading.
[0013] The utility model adopts two water seal groove structures, the first water seal groove 1 is installed on the hopper, and the second water seal groove 2 is installed on the coke oven. When loading, the first water seal groove 1 moves with the hopper to the top of the second water seal groove 2, and the first water seal groove 1 and the second water seal groove 2 are connected and sealed by a sealing ring assembly. In this way, by injecting water into the first water seal groove 1 and the second water seal groove 2, when the water in the first water seal groove 1 is full, it enters the second water seal groove 2 through the first overflow groove 4, and when the water in the second water seal groove 2 is full, it flows out through the second overflow groove 5.
[0014] The sealing ring assembly includes a movable sealing ring 6 mounted on the second water seal groove 2. The movable sealing ring 6 is positioned outside the outer ring of the second water seal groove 2. An annular baffle 7 is mounted on the inner wall of the top of the movable sealing ring 6, which is secured to the flange plate at the bottom of the hopper. The bottom of the movable sealing ring 6 is designed to fit over the inner ring of the first water seal groove 1. The hopper 3 is also equipped with a lift control mechanism for controlling the raising and lowering of the movable sealing ring. The sealing ring assembly seals the gap between the first and second water seal grooves 1 and 2. The seal is achieved by the downward movement of the movable sealing ring 6, which fits over the inner ring of the first water seal groove 1. The height of the movable sealing ring 6 is the same as the height from the second overflow groove 5 to the bottom of the second water seal groove 2, so it does not affect the overflow of the second water seal groove 2 or the movement of the hopper. The movable sealing ring 6 is controlled by a lift control mechanism. The lift control mechanism includes a fixed plate 8 mounted on the hopper. Lift control cylinders 9 are mounted on both sides of the fixed plate 8. The piston rods of the lift control cylinders 9 are connected to the outer wall of the movable sealing ring 6. The movable sealing ring 6 is controlled to move by two lifting control cylinders 9, and the control is convenient.
[0015] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.
