Technical Field
[0001] The utility model relates to the technical field of water seal devices for smoke guide hole seats in ramming coke ovens, in particular to an automatic liquid level control device for a water seal groove of a smoke guide hole seat. Background Art
[0002] In the coking field, the escape of coke oven gas and smoke during the ramming coke charging process, as well as the emission of smoke during the coke discharge process are the main sources of pollution in the coke oven production. In order to reduce pollution, water seal grooves are often set at the smoke guide hole seat for water sealing to prevent the leakage of coke oven raw gas and smoke and cause pollution.
[0003] At present, when the commonly used water seal tank is replenished with water, a special person is required to open the valve and monitor the water level in the water seal tank on site so that the valve can be closed in time. If the valve is not closed in time, the water in the water seal tank will flow away from the return water device, resulting in a waste of water resources and increasing the difficulty of chemical water treatment. Correspondingly, if the valve is not opened in time to supply water, the water seal tank is prone to water shortage, causing the water seal tank to burn out. However, in the actual working process, there are a large number of coke oven water seal tanks, and the burden on the supervisors is heavy, which makes it easy for mistakes to occur during work. Therefore, there is an urgent need for a smoke guide hole seat water seal tank liquid level automatic control device to automatically monitor and adjust the water level in the water seal tank. Utility Model Content
[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a liquid level control device for the water seal groove of a smoke guide hole seat, and the technical solution it solves is that it includes a smoke guide hole seat, characterized in that the outer wall of the smoke guide hole seat is fixedly connected to the water seal groove, and a water supply device corresponding to it is arranged on the outside of the water seal groove, a vertical pole is fixedly connected to the left side of the upper edge of the water seal groove, and two mounting grooves arranged vertically at intervals are opened at the right end of the vertical pole, and photosensitive switches for controlling the water supply device are respectively fixedly connected in the two mounting grooves, the left side wall of the water seal groove is fixedly connected to a connecting rod, the end of the connecting rod is fixedly connected to a sliding sleeve, and the sliding sleeve is vertically slidably matched with a sliding rod, the lower end of the sliding rod is fixedly connected to an air raft located in the water seal groove, the outer edge surface of the sliding rod is fixedly connected to a cross bar, the end of the cross bar is fixedly connected to a support plate, and the support plate is fixedly connected to a light shielding plate used in conjunction with the photosensitive switch.

DETAILED DESCRIPTION
[0017] The following is combined with Figure 1-5 The specific implementation methods of the present invention are further described in detail.
[0018] Embodiment 1, the technical solution is that when the new type is in use, the air raft 9 can float up and down as the water level in the water seal tank 2 rises and falls. As the water supply device supplies water, when the liquid level in the water seal tank 2 reaches the upper limit, the air raft 9 floats to the highest point along the liquid level. At this time, the slide bar 8 connected to the air raft 9 will also move upward along the sliding sleeve 7 to the highest point, and the support plate 11 fixedly connected to the slide bar 8 through the cross bar 10 will also move to the highest point, and the shading sheet 12 on the support plate 11 corresponds to the photosensitive switch 5 located on the upper side, and the photosensitive switch 5 is shielded by the shading sheet 12 and is open. The electricity then controls the solenoid valve 14 to close; accordingly, as the water level in the water seal tank 2 drops, the air raft 9 and the slide bar 8 will also drop with the water level. When the water level drops to the lower limit, the slide bar 8 moves down to the lowest point. At this time, the shading plate 12 corresponds to the photosensitive switch 5 on the lower side and shields the photosensitive switch 5 on the lower side, and then the photosensitive switch 5 on the lower side is energized and controls the solenoid valve 14 to open, so that the water supply device supplies water to the water seal tank 2. The utility model has a simple structure, is easy to use, and has strong usability. The water supply device can be automatically opened and closed according to the change of water level, and the liquid level in the water seal tank 2 can be controlled and adjusted.
[0019] Example 2. Based on Example 1, when the present invention is in use, when the upper photosensitive switch 5 is covered and shielded by the shading sheet 12, the upper photosensitive switch 5 will control the solenoid valve 14 to close, thereby stopping the water supply device from supplying water to the water seal tank 2; when the lower photosensitive switch 5 is covered and shielded by the shading sheet 12, the lower photosensitive switch 5 will control the solenoid valve 14 to open, thereby allowing the water seal water to be supplied to the water seal tank 2 through the water supply pipe 13. The water seal tank 2 is filled with an appropriate amount of water, and the sealing plate 18 and the sealing cover 19 can be used to water-seal the smoke guide hole seat 1. Furthermore, the cover plate 17 on the smoke guide hole seat 1 can also prevent gas and smoke from escaping. The two photosensitive switches 5 are installed in the installation slot 4 on the vertical pole 3 and are electrically connected to the solenoid valve 14 in the water supply device. The slide rod 8 can be vertically displaced along the slide sleeve 7 fixedly connected to the connecting rod 6 as the air raft 9 floats and sinks, thereby causing the shading plate 12 on the support plate 11 to move vertically synchronously with the slide rod 8. The shading plate 12 can cooperate with the shading plate 12 during the vertical movement process to control the water supply device.
[0020] Embodiment 3, based on embodiment 1, in order to limit the vertical movement of the slide rod 8 along the slide sleeve 7, a vertically arranged slide groove 15 is opened on the outer edge of the slide rod 8, and a guide key 16 is fixedly connected to the inner wall of the slide sleeve 7 and vertically slides with the slide groove 15.
