Description

Technical Field

[0001] The utility model relates to the technical field of dry quenching coke equipment, and in particular to a dry quenching coke oven cover. Background Art

[0002] The cover of the CDQ oven is located at the coke loading entrance of the CDQ oven. It usually forms a seal with the water in the water seal tank to ensure that the upper opening of the oven is in a closed state. When the CDQ oven is loading red coke, the cover must be opened to move the oven outlet. After the red coke is loaded, the cover moves back to the oven outlet. Every time the cover is opened and closed, it must pass through the upper part of the oven outlet, and the temperature of the oven outlet is as high as more than 1000 degrees. Therefore, every movement of the cover involves a process of heating up and cooling down. The material at the edge of the cover is frequently heated up and down, which seriously affects its life.

[0003] The dry coke quenching oven cover is a component used for household products. However, the existing dry coke quenching oven cover is heavy and large in size, and the volume of the oven cover and the oven body is relatively large. When red coke is injected, due to the principle of heat rise, a large amount of high-temperature dust and toxic and harmful gases are generated during the coke loading process and escape into the atmosphere, causing serious pollution to the environment. At the same time, high-temperature toxic and harmful gases enter the elevator machinery room, which will seriously affect the service life of the elevator drum, wire rope and various electrical components, causing frequent failures in the lifting and running systems. How to effectively collect the dust spilled from the coke tank cover is a problem that needs to be solved urgently.

[0004] Compared with the prior art, most of the current dry quenching coke oven covers have poor sealing effects due to their high weight and the fact that they are not easy to seal well when aligned with the dry quenching coke oven. In addition, most of the covers are heavy, which may cause a large impact when they land on the coke oven mouth, thus reducing the service life of the cover. Therefore, a dry quenching coke oven cover is proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the problems in the prior art that the furnace cover is inevitably heavy and the high temperature resistant material is painted, which causes material loss due to the fluctuation between high temperature and low temperature, and the replacement of the furnace cover is expensive. In addition, the coke oven cover also requires a certain sealing effect to prevent harmful gases from overflowing from the device and polluting the air. Therefore, a dry quenching coke oven cover is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A protective device for electrical automation, comprising a dry quenching coke oven body and a heat-insulating sealed cover body, wherein a support column for supporting the heat-insulating sealed cover body is arranged outside the heat-insulating sealed cover body, a damping sliding block is arranged outside the support column, a buffer mechanism is arranged inside the heat-insulating sealed cover body, the buffer mechanism comprises a damping spring inside the heat-insulating sealed cover body, and the damping spring is fixedly connected to a cross brace body;

[0008] When sealing is required, a furnace body slide groove for sliding of the friction body is provided on the outside of the dry quenching coke oven body, the friction body is fixedly connected with a rotating rod, a fixed shaft for folding is provided on the side of the rotating rod away from the friction body, the rotating rod is rotatably connected with the fixed shaft, when the heat insulating sealing cover is fixed on the surface of the dry quenching coke oven body, the friction body rubs on the surface of the furnace body slide groove, when the heat insulating sealing cover contacts the dry quenching coke oven body, the friction body is stuck on the surface of the furnace body slide groove, and the heat insulating sealing cover falls on the surface of the dry quenching coke oven body under the buffering of the shock-absorbing spring.

[0009] The above technical solution further includes:

[0010] The surface of the furnace body slide groove is made of wear-resistant material, the surface of the insulating sealing cover body is provided with a high-temperature resistant insulating body, the insulating sealing cover body is fixedly connected to the insulating body, the interior of the furnace body slide groove is provided with a friction groove for high-temperature resistance and wear resistance, the exterior of the insulating body is provided with a flame retardant plate for further insulation, the insulating body is fixedly connected to the flame retardant plate, the interior of the insulating sealing cover body is provided with a high-temperature resistant sealing ring, and the insulating sealing cover body is fixedly connected to the sealing ring.

[0011] The heat-insulating sealing cover is slidably connected to the sliding block, an insulating body for isolating the heat inside the dry quenching coke oven is arranged inside the heat-insulating sealing cover, a cross-bracing body with a supporting device is arranged outside the support column, the support column is fixedly connected to the cross-bracing body, and the sliding block is slidably connected to the cross-bracing body.

[0012] The chassis is provided with heat dissipation holes on the outside for dissipating heat from the fan to ensure the fan maintains a low temperature during operation.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, after adding red coke, it is necessary to clamp the heat-insulating sealing cover body on the outside of the dry quenching coke oven body. Then, when the heat-insulating sealing cover body is covered, the friction body first contacts the furnace body slide groove outside the dry quenching coke oven body, and then slides inside the furnace body slide groove. The damping spring inside the sliding block performs internal buffering. The heat-insulating sealing cover body is basically made of high-temperature resistant alloys and other materials, and a certain buffer is required when falling. Then, the friction body rubs on the friction groove surface inside the furnace body slide groove to further play a friction role, so that the heat-insulating sealing cover body slowly falls on the surface of the dry quenching coke oven body. Then, the sealing ring inside the heat-insulating sealing cover body is a high-temperature resistant soft material that can well resist the furnace mouth on the surface of the dry quenching coke oven body. The heat-insulating body is a plate body of high-temperature resistant material, which can well isolate the internal high temperature and further flame retardant under the action of the flame retardant plate to prevent the heat-insulating sealing cover body from being damaged by excessive temperature.

[0015] 2. In the utility model, the surface of the furnace body slide groove contains wear-resistant material, which can well ensure the long-term use of the furnace cover. The surface of the heat-insulating and sealed cover body is provided with a high-temperature resistant insulation body, which can well isolate a part of the temperature, thereby increasing the life of the furnace cover. A friction groove that is resistant to high temperature and wear is provided inside the furnace body slide groove to ensure long-term use. A flame-retardant plate is provided on the surface of the insulation body to well ensure that the local temperature is too high and reduce the life of the furnace cover.

[0025] When sealing is required, a furnace body slide groove 3 for sliding of the friction body 9 is provided on the outside of the dry quenching coke oven body 1, and the friction body 9 is fixedly connected with a rotating rod 7. A fixed shaft 8 for folding is provided on the side of the rotating rod 7 away from the friction body 9. The rotating rod 7 is rotatably connected to the fixed shaft 8. When the heat-insulating sealing cover 2 is fixed on the surface of the dry quenching coke oven body 1, the friction body 9 rubs on the surface of the furnace body slide groove 3. When the heat-insulating sealing cover 2 contacts the dry quenching coke oven body 1, the friction body 9 is stuck on the surface of the furnace body slide groove 3. The heat-insulating sealing cover 2 falls on the surface of the dry quenching coke oven body 1 under the buffering of the shock-absorbing spring 11.

[0026] The working principle of a dry quenching coke oven cover proposed by the utility model is that after adding red coke, the heat-insulating sealing cover body 2 needs to be stuck on the outside of the dry quenching coke oven body 1, and then when the heat-insulating sealing cover body 2 is covered, the friction body 9 first contacts the furnace body slide groove 3 outside the dry quenching coke oven body 1, and the friction body 9 slides inside the furnace body slide groove 3.

[0029] The heat-insulating sealing cover body 2 is slidably connected to the sliding block 6. An insulating body 4 for isolating the internal heat of the dry quenching coke oven body 1 is arranged inside the heat-insulating sealing cover body 2.

The support column 5 is fixedly connected to the cross-bracing body 10, and the sliding block 6 is slidably connected to the cross-bracing body 10.
