[0003] In the prior art, the water seal tank is a single-layer structure. With the long-term use of the water seal tank, coke powder scattered during the coke loading process and coke powder dissipated with the high-temperature gas fall into the water seal tank and accumulate at the bottom of the water seal tank, affecting the heat transfer at the bottom of the water seal tank and even causing cracks and water leakage. Utility Model Content

[0004] In order to improve the problems in the above background technology, the utility model provides a water seal device for a dry quenching coke oven.

[0005] The utility model provides a water seal device for a dry quenching coke oven, which adopts the following technical solution:

[0006] A water seal device for a dry quenching coke oven comprises a water seal groove installed at the dry quenching coke oven mouth, a partition frame is placed in the water seal groove, the partition frame comprises a plurality of partitions spliced ​​together, adjacent partition splicing positions are provided with splicing grooves, a support frame is welded to the edge of the partition, a hook is provided on the top of the support frame and is hung on the outer edge of the water seal groove.

[0007] Preferably, water-permeable holes are distributed at intervals on the partition.

[0008] Preferably, the outer side of the water seal groove is connected to a circulation pipeline, a filter and a water pressure pump are provided on the circulation pipeline, and the circulation pipeline is connected to a cooling water tank.

[0009] Preferably, a heat-resistant plate is provided inside the water-sealing groove, an interlayer is provided at the contact position between the heat-resistant plate and the water-sealing groove, and the heat-resistant plate is a ceramic plate, which insulates heat.

[0010] To sum up, the utility model has the following beneficial technical effects: on the basis of the existing single-layer water seal groove structure, the utility model assembles a partition frame in the water seal groove, and the coke powder falls on the partition frame. The hooks arranged on the edge of the partition are hooked on the outer edge of the water seal groove, which is convenient for disassembly and cleaning of the partition and extends the service life of the water seal groove; the heat-resistant ceramic plate on the inside of the water seal groove isolates heat, and reduces the contact area with the water seal groove through the interlayer, thereby protecting the water seal groove.
