Description

Technical Field

[0001] The invention discloses a coke tank bottom gate seal, which relates to the technical field of coke quenching equipment in the coking industry, and in particular to a coke tank bottom gate seal structure. Background Art

[0002] The coke tank bottom gate seal is an important component of the coke tank. Whether its structural form is reasonable determines whether it can prevent coke leakage and seal. The existing sealing form has the following major disadvantages:

[0003] 1. The function of preventing coke leakage relies only on the protection formed by the bottom gate lining and the flange plate at the bottom of the coke tank. A large amount of coke powder squeezes into the space between the lining plate and the flange plate.

[0004] 2. A large amount of coke powder squeezes into the space between the liner and the flange plate, causing the bottom gate to not close tightly.

[0005] 3. A large amount of coke powder squeezes into the space between the liner and the flange plate, causing damage to the ceramic fiber rope and failing to seal the dust;

[0006] 4. Once the ceramic fiber rope is damaged, it is not easy to replace.

[0007] In view of the problems existing in the above-mentioned prior art, it is very necessary to research and design a new type of coke tank bottom gate seal to overcome the problems existing in the prior art. Summary of the Invention

[0008] In response to the technical problems of the prior art, such as the extrusion of rubber powder from the protective space formed between the bottom gate lining and the bottom flange of the coke drum, which damages the ceramic fiber rope and fails to seal dust, and the difficulty in replacing the ceramic fiber rope, a coke drum bottom gate seal is provided. The present invention primarily utilizes the ring platform structure on the upper surface of the bottom gate lining, the coke drum bottom lining, the connecting square steel, and the sealing round steel to form a four-layer anti-coke leakage structure (a labyrinth structure), which prevents coke leakage and thus solves the problems of lax sealing near the coke drum bottom gate, serious coke leakage, and safety hazards.

[0009] The technical means adopted in the present invention are as follows:

[0010] A coke tank bottom gate seal, comprising a coke tank bottom and a bottom gate; the bottom gate is installed at the lower part of the coke tank bottom; and is characterized by:

[0011] Furthermore, the bottom gate is welded from heat-resistant stainless steel plates and connected to the bottom gate lining plate made of heat-resistant cast steel by bolts;

[0012] Furthermore, the coke tank bottom is welded from steel plates and section steel and is located at the bottom of the coke tank body; a coke tank bottom liner is assembled on the coke tank bottom, and the bottom end of the coke tank bottom liner is located above the middle upper end surface of the bottom gate liner, forming the first layer of coke leakage prevention structure;

[0013] Furthermore, the bottom of the coke tank is equipped with a sealing round steel made of curved round steel, which is located next to the inner inclined surface of the bottom gate lining, forming a second anti-coke leakage structure;

[0014] Furthermore, the bottom of the coke tank is equipped with a connecting square steel, which is located next to the upper outer facade of the bottom gate lining; the side facade of the connecting square steel and the facade of the bottom gate lining form a third anti-coke leakage structure; the bottom end face of the connecting square steel and the upper end face of the bottom gate lining form a fourth anti-coke leakage structure.

[0015] Further, the connecting square steel is assembled to the bottom of the coke tank bottom by means of bolts and connecting angle steel;

[0016] Furthermore, porcelain fiber felt is installed between the connecting square steel and the connecting angle steel.

[0017] Furthermore, the lower end of the porcelain fiber felt is in contact with the upper plane of the bottom gate lining, thereby performing a sealing function.

[0018] Furthermore, the bottom gate lining forms a maze structure with the coke tank bottom lining, connecting square steel and sealing round steel through the ring structure on its upper end face, which prevents coke leakage.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. The coke tank bottom gate seal provided by the present invention adopts multiple anti-coke leakage devices to ensure that a large amount of coke powder will not overflow during the use of the coke tank

[0021] 2. The coke drum bottom gate seal provided by the present invention avoids the problem of the bottom gate not closing tightly due to coke powder being trapped between the bottom flange of the coke drum and the bottom gate lining;

[0022] 3. The coke tank bottom gate seal provided by the present invention and the dust prevention device provided can effectively prevent dust from overflowing;

[0023] 4. The coke tank bottom gate seal provided by the present invention provides a dustproof device that is easy to disassemble and can be replaced in time after damage.

[0024] 5. The coke tank bottom gate seal provided by the present invention solves the problems of loose sealing near the coke tank bottom gate, serious coke leakage, and potential safety hazards.

[0025] In summary, the technical solution of the present invention solves the problems in the prior art where rubber powder is squeezed out from a protective space formed between the bottom gate lining and the bottom flange of the coke drum, causing damage to the ceramic fiber rope and failing to seal the dust, and the ceramic fiber rope is difficult to replace.
