Description

Technical field:

[0001] The utility model belongs to the field of coal coking production, in particular to a coke oven top water seal device. Background technology:

[0002] A coke oven (abbreviated as coke oven) is a furnace used to refine coke. A coke oven is usually a furnace made of refractory bricks and refractory blocks, used to oxidize coal to produce coke, and is the main thermal equipment for coking.

[0003] In the prior art, the water seal on the top of the coke oven generally adopts a circulating water replenishment method to achieve a water seal state. The main principle is to continuously replenish water into the water seal tank, and the water overflowing from the water seal tank flows back to the collection pool through the water return pipe laid on the top of the furnace, and is then pumped to the top of the furnace by a water pump for water replenishment and recycling. Although this method can always keep the water in the water seal tank sufficient, it requires the water pump to keep running all the time, which not only leads to a significant increase in power consumption and a large cost investment in the water seal on the top of the coke oven, but also the water pump is prone to damage after a long period of operation, resulting in the water in the water seal tank cannot be replenished in time, and the coke oven top is prone to gas leakage, which may cause explosions and other safety accidents in severe cases. Utility model content:

[0004] The utility model aims to provide a coke oven top water seal device, and overcomes the above-mentioned deficiencies of the prior art, and effectively solves the existing problems of the existing water seal mode.

[0005] The content of the utility model: A water seal device for a coke oven top comprises a coke oven top, a sealing cover is covered at the top opening of the coke oven top, a water seal groove is installed on the coke oven top, a water supply pipe is horizontally connected to the side wall of the water seal groove, a cylinder is vertically installed at the drainage end of the water supply pipe, the water supply pipe is connected to the cylinder through a through opening, a sleeve is coaxially slidably connected in the cylinder, a sliding limit assembly is arranged on the sleeve, a water replenishment port and a drainage port are respectively opened on the top and bottom side walls of the sleeve, and a suspension plate is installed at the bottom end of the sleeve.

[0006] Furthermore, the sliding limit assembly includes a slide bar, which is vertically mounted on the outer wall of the sleeve, and a groove matching the slide bar is formed on the inner wall of the cylinder, and the slide bar slides in the groove.

[0007] Furthermore, the inner wall of the cylinder is slidably fitted with the outer wall of the sleeve.

[0008] Furthermore, a limit card is installed on the top of the sleeve.

[0009] Furthermore, the suspension plate and the limiting card are uniformly circular in shape.

[0010] Furthermore, the suspension plate is made of metal foam.

[0011] The beneficial effects of the utility model are as follows: when the water supply pipe is connected with the water replenishment port opened on the sleeve, the water supply pipe can replenish sufficient water into the water seal groove in time, which not only realizes the automatic replenishment of water in the water seal groove and reduces power consumption, with low cost investment, but also avoids the occurrence of gas leakage accidents and ensures safe production.

[0014] In the figure, 1 is a coke oven roof, 2 is a sealing cover, 3 is a water seal groove, 4 is a water supply pipe, 5 is a cylinder, 6 is a through port, 7 is a sleeve, 8 is a water supply port, 9 is a drain port, 10 is a suspension plate, 11 is a slide bar, 12 is a groove, and 13 is a limit card. Specific implementation method:

[0015] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings:

[0016] like Figure 1 to Figure 2 As shown, a coke oven top water seal device comprises a coke oven top 1, a sealing cover 2 is covered at the top opening of the coke oven top 1, a water seal groove 3 is installed on the coke oven top 1, a water supply pipe 4 is horizontally connected to the side wall of the water seal groove 3, a cylinder 5 is vertically installed at the drainage end of the water supply pipe 4, the water supply pipe 4 is connected to the cylinder 5 through a through port 6, a sleeve 7 is coaxially slidably connected in the cylinder 5, a sliding limit assembly is arranged on the sleeve 7, and a water replenishment port 8 and a drainage port 9 are respectively opened on the top and bottom side walls of the sleeve 7. Mouth 9, a suspension board 10 is installed at the bottom end of the sleeve 7, the sliding limit assembly includes a slide bar 11, the slide bar 11 is vertically installed on the outer wall of the sleeve 7, a groove 12 matching the slide bar 11 is opened on the inner wall of the cylinder 5, the slide bar 11 slides in the groove 12, the inner wall of the cylinder 5 slides and fits with the outer wall of the sleeve 7, a limit card 13 is installed on the top end of the sleeve 7, the suspension board 10 and the limit card 13 are uniformly circular, and the suspension board 10 is made of metal foam.

[0017] Specifically, when the water supply pipe 4 is connected to the water replenishment port 8 opened on the sleeve 7 , the water supply pipe 4 can replenish water into the water seal groove 3 .

[0018] In actual use, when the amount of water in the water seal groove 3 evaporates and decreases, the suspension plate 10 and the horizontal plane simultaneously drop, and at this time, the sleeve 7 slides downward in the cylinder 5, and when the water replenishment port 8 opened on the sleeve 7 is connected with the water supply pipe 4, the industrial water in the water supply pipe 4 flows into the sleeve 7 through the water replenishment port 8, and flows into the water seal groove 3 through the drain port 9. When the water level gradually rises, the suspension plate 10 floating on the water surface is also driven to rise, and when the suspension plate 10 rises, it pushes the sleeve 7 to slide upward in the cylinder 5, and when the water replenishment port 8 is disconnected from the water supply pipe 4, , the water supply pipe 4 completes the water replenishment work in the water seal groove 3; when the slide bar 11 slides in the groove 12, it can prevent the sleeve 7 from rotating randomly when sliding up and down in the cylinder 5, so that the water supply pipe 4 and the water replenishment port 8 can be accurately connected; the inner wall of the cylinder 5 and the outer wall of the sleeve 7 slide and fit together, so that when the water is not replenished, the outer wall of the sleeve 7 can block the opening 6, avoiding excessive water from entering the water seal groove 3, saving water resources; when the coke oven is shut down for maintenance, the water in the water seal groove 3 is discharged, and the limit card 13 can prevent the sleeve 7 from sliding out of the cylinder 5.

[0019] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
