Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and more specifically, it relates to a plug brick laying device and method for the oven top drying hole of a coke oven. Background Technology

[0002] During the later stages of the hot-state drying process of the coke oven, the temperature in the coke oven carbonization chamber reaches 900℃. Before commissioning, the pre-reserved drying holes on the top of the coke oven need to be sealed with plug bricks. Before sealing, the pre-reserved holes on the top of the carbonization chamber wall connect the coke oven carbonization chamber and the combustion chamber in series, allowing for heat recycling. After sealing and commissioning, the carbonization chamber and the combustion chamber are isolated from each other. To ensure that the coking coal is fully sealed, does not burn, and does not produce black smoke, the quality of the plug brick installation must not affect the coke forming quality or the environmental quality of the coke oven.

[0003] When the temperature in the coke oven carbonization chamber reaches 900℃, the dust removal hole cover on the top of the oven is opened, and L-shaped hooks are used to control the plug bricks to plug the holes. Refractory mortar is then applied. Due to the high temperature during construction, fireproof asbestos clothing and fireproof face shields and gloves must be worn during the plugging process. Affected by the hot air flowing from the carbonization chamber, the construction personnel cannot accurately position the plugs during the plugging process, resulting in problems such as plug bricks falling off, excessively long plugging time causing the carbonization chamber temperature to drop excessively, and burns to the construction personnel.

[0004] Traditional construction methods are simple and arbitrary, and pose significant safety hazards during the construction process, failing to meet the current requirements for efficient construction progress. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention belongs to the field of building construction technology, and more specifically, it relates to a plug brick laying device for the oven top drying hole of a coke oven.

[0026] # Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, in the following description, descriptions of well-known structures are omitted to avoid unnecessarily obscuring the concept of the invention.

[0028] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0029] A plug brick installation device and method for coke oven top drying holes are disclosed. Several drying holes are provided on the top of the coke oven. Dust removal holes need to be opened simultaneously with the drying holes. Therefore, this embodiment includes a flow guiding device and a installation device. The flow guiding device can be placed next to the dust removal hole on the top of the coke oven. The device guides the hot air discharged from the drying holes, slowing down the loss of hot air and providing insulation and protection for workers. A plug brick needs to be placed at the drying hole. The installation device can fix and move the plug brick to the drying hole, completing the installation of the plug brick.

[0030] Preferably, such as Figure 1 The diagram shows the structure of the flow guiding device in this embodiment. The flow guiding device consists of a cylindrical column 6 and a flow guiding column 5 located inside the column core of the column 6. An insulating lining is provided between the column 6 and the flow guiding column 5. In this embodiment, the insulating lining is an asbestos lining. By providing an asbestos lining inside the flow guiding device, heat loss caused by prolonged opening time during construction is reduced. A base 8 is provided at the bottom of the flow guiding device. In this embodiment, the base 8 is provided with an asbestos skirt base with adsorption and heat absorption capabilities. The column 6 of the flow guiding device can be stably placed on the oven drying hole on the top of the coke oven through the base 8. The asbestos skirt can absorb the hot air discharged from the oven drying hole and prevent the heat from escaping. Lifting rods 7 are provided on both sides of the flow guiding device. There are at least two lifting rods 7, which are respectively positioned opposite each other on the outside of the flow guiding device. The lifting rods 7 can be used to move the heat-absorbing flow guiding device without harming the workers due to excessive temperature, thus improving the safety of the device.

[0031] Preferably, such as Figure 2The diagram shows the structure of the bricklaying device in this embodiment. Based on the operating rod 2, handles and a balance rod 4 are respectively set at both ends of the operating rod 2. A clamping device 3 is installed at one end of the balance rod 4. In this embodiment, the clamping device 3 is a bricklaying hook, which is made of threaded steel with a diameter smaller than that of the hole in the plug brick. The plug brick can be fixed and moved by the clamping device 3. A protective plate 1 is set at the handle. The protective plate 1 can ensure that the hot air will not burn the workers during the movement of the plug brick, thus protecting the safety of the user. In this embodiment, the balance rod 4 is set as a steel pipe that is perpendicular to the operating rod 2 and is installed by threaded rotation. The balance rod 4 can adjust the use angle of the clamping device 3 before the clamping device 3 picks up the plug brick, which facilitates the clamping and installation of the plug brick.

[0032] During the construction of the plug bricks, simultaneously open the cover of the oven hole to be constructed and the adjacent oven hole cover. Place the flow guiding device at the adjacent oven hole with the cover open to guide the hot airflow rising from the carbonization chamber, while ensuring that the base 8 completely covers the dust hole. Use the masonry device to fix the plug bricks on the clamping device 3, and simultaneously apply refractory mortar to the outside of the plug bricks. After adjusting the construction direction by adjusting the balance bar 4, install the plug bricks into the oven hole. After the construction is completed, remove the clamping device from the plug bricks, cover the oven hole cover, and simultaneously use the lifting rod 7 to remove the flow guiding device. Then repeat the above steps to complete the plug brick masonry of all oven holes.

[0033] By adopting the above technical solutions, the safety of the plug brick masonry for the oven holes is improved, preventing burns to construction workers; construction efficiency is accelerated, greatly shortening the construction progress; heat loss caused by long opening time during construction is reduced, while effectively ensuring the quality of plug brick masonry.

[0034] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
