Description

Technical Field

[0001] This utility model relates to the field of dry quenching technology in the coking industry, and in particular to a inclined maintenance support device. Background Technology

[0002] Dry quenching, as opposed to wet quenching, refers to a quenching method that uses inert gas to cool red-hot coke. In the dry quenching process, red-hot coke is loaded from the top of the quenching furnace. Low-temperature inert gas is blown into the red-hot coke layer in the cooling section of the furnace by a circulating fan, absorbing the sensible heat of the coke. The cooled coke is discharged from the bottom of the furnace. High-temperature inert gas exiting the furnace's annular flue flows through the dry quenching boiler for heat exchange, generating steam. The cooled inert gas is then blown back into the furnace by the circulating fan, thus circulating the inert gas within a closed system.

[0003] The dry quenching furnace is the main equipment of the dry quenching coke unit. Different specifications of dry quenching furnaces are selected for dry quenching operation units with different processing capacities. The main functions of the dry quenching furnace body include the following two aspects: First, it serves as a storage device for red-hot coke, pre-storing a portion of it. Second, it serves as a device for quenching red-hot coke, reducing the coke temperature to below 200℃ through a blower installed at the bottom of the dry quenching furnace.

[0004] A dry quenching furnace is mainly used for pre-storing and cooling coke during dry quenching. It consists of a pre-storage section, an inclined chute zone, and a cooling section. The furnace is a vertical trough with a circular cross-section, its outer shell made of steel plates and structural steel, lined with heat-insulating and wear-resistant materials, and topped with an annular water seal trough. The upper part of the furnace is the pre-storage section, the middle is the inclined chute zone, and the lower part is the cooling section. The pre-storage section receives intermittently charged red-hot coke and acts as a buffer to compensate for production fluctuations. The inclined chute zone is a crucial component of the dry quenching furnace; its main function is to absorb the sensible heat of the red-hot coke from the low-temperature circulating gas supplied from the bottom of the furnace, which then exits through the inclined chute and annular gas passage, and flows through the dry quenching boiler for heat exchange. The refractory-lined wall supporting the section between every two inclined chute openings is commonly called a "corbel." The cooling section, located at the bottom of the furnace, facilitates heat exchange between the red-hot coke and the low-temperature circulating gas, cooling the coke before discharge, thus achieving the purpose of cooling the coke.

[0005] Due to the continuous operation of the dry quenching system, red-hot coke is continuously loaded into the quenching furnace from the top, passes through the pre-storage chamber and cooling chamber, and is discharged through the coke discharge device. Therefore, the quenching furnace is constantly under high temperatures. Over time, the refractory materials inside the furnace are corroded and worn by the high-temperature coke, flue gas, and coke dust, resulting in varying degrees of damage and severely affecting normal dry quenching production. Therefore, it is necessary to shut down the dry quenching furnace annually to cool it down and repair the internal refractory materials. The most severely damaged part of the internal refractory materials is the corbel section in the inclined section, which is rebuilt and repaired during annual maintenance.

[0006] This patent describes a support device for the maintenance of inclined grate brackets in dry quenching furnaces. This device supports and protects the top of the inclined grate openings at both ends of the bracket, ensuring safety during bracket removal and replacement operations. It prevents the risk of partial collapse of the inclined grate brackets due to factors such as high vibration or large removal areas during construction or replacement. Field testing has shown excellent results, greatly facilitating the inspection and maintenance of inclined grate brackets in dry quenching furnaces. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The purpose of this utility model is to provide a ramp maintenance support device to solve the problems existing in the prior art. It has a simple structure, is easy to use, and effectively ensures the safety during the removal and replacement of the bracket.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] This utility model provides a ramp maintenance support device, including: a buffer member, a first support member, a connecting member, and a second support member. The top of the buffer member is used to contact the arch of the ramp entrance; the top of the first support member is used to contact the bottom of the buffer member and can support the arch of the ramp entrance; one end of the connecting member is used to slide and connect with the first support member and can maintain the slid position; the bottom of the second support member is used to place on the upper part of the support beam of the maintenance platform, and the top of the second support member is used to slide and connect with the connecting member and can maintain the slid position. By placing the second support member on the upper part of the support beam of the maintenance platform and placing the buffer member on the bottom of the ramp entrance arch, rotating the connecting member makes the first support member press against and support the buffer member, which can realize flexible height adjustment, ensuring that the support device can adapt to ramp entrances and maintenance platform support beams of different heights, making the support more stable and reliable. The buffer member forms a buffer layer between the support device and the refractory material of the ramp entrance, preventing the support device from directly contacting the refractory material and avoiding damage to the refractory material.

[0029] In a preferred embodiment, the inclined ramp maintenance support device further includes a stabilizer. The stabilizer is placed on the upper part of the support beam of the maintenance platform and is positioned between the second support and the support beam of the maintenance platform to limit the sliding of the bottom of the second support. The stabilizer enhances the stability of the support device on the maintenance platform and prevents the second support from sliding during use, thereby ensuring reliable support of the entire support device and improving the safety of maintenance operations.

[0030] In a preferred embodiment, the first support member includes a first support base 1 and a first lead screw 2. The top of the first support base 1 is fixedly connected to the top of the first lead screw 2. A first screw hole is provided on the top of the connector, and the first lead screw 2 is threaded into the first screw hole. The first support base 1 is snap-fitted into the buffer member. Rotating the connector can cause the first support base 1 to rise or fall, so that the first support base 1 presses the buffer member against the arch of the inclined ramp. The combination of the first support base 1 and the first lead screw 2, through the threaded connection and cooperation with the connector, achieves precise height adjustment. The snap-fit ​​connection to the buffer member makes the support more stable and facilitates installation and disassembly. Rotating the connector adjusts the height, making the operation convenient and quick, and improving work efficiency.

[0031] In a preferred embodiment, the buffer is a wooden mold. The top of the first support 1 is provided with a first snap-fit ​​groove. The bottom of the wooden mold is used to snap into the first snap-fit ​​groove, and the top of the wooden mold is used to extend out of the first snap-fit ​​groove and contact the ramp arch. As a buffer, the wooden mold has two advantages: firstly, the relatively soft wood material can reduce damage to the refractory material of the ramp arch; secondly, the snap-fit ​​connection method makes the installation more stable and facilitates the replacement of wooden molds of different specifications to adapt to different ramp sizes.

[0032] In a preferred embodiment, the top of the wooden mold is an arc-shaped portion that matches the curvature of the ramp arch. This arc-shaped design better conforms to the shape of the ramp arch, increasing the contact area and improving the stability and uniformity of the support. Simultaneously, it reduces localized pressure concentration, providing better protection for the refractory material of the arch.

[0033] In a preferred embodiment, the second support member includes a second support base 4, a second lead screw 5, and a second lead screw. The second support base 4, the second lead screw 5, and the second lead screw are fixedly connected to the bottom of the second lead screw. A second threaded hole is provided at the bottom of the connector, and the second lead screw is used for threaded connection with the second threaded hole. The second support base 4, the second lead screw 5, and the second lead screw 5 are used for snap-fit ​​connection with the stabilizer. Rotating the connector allows the connector to rise or fall along the second lead screw, so that the second support base 4, the second lead screw 5, and the second lead screw 5 press the stabilizer against the support beam of the maintenance platform. The structural design of the second support base 4, the second lead screw 5, and the second lead screw is similar to that of the first support member, thus achieving height adjustability. The snap-fit ​​connection with the stabilizer ensures the stability of the second support member's position, thereby further enhancing the stability of the entire support device on the maintenance platform.

[0034] In a preferred embodiment, the stabilizing component is a wooden anti-slip component. The bottom of the second support base 4 and the second lead screw 5 is provided with a second locking groove. The top of the wooden anti-slip component is used to lock into the second locking groove, and the bottom of the wooden anti-slip component extends out of the second locking groove and contacts the upper part of the support beam of the maintenance platform. The wooden anti-slip component not only provides anti-slip properties but also increases the friction with the support beam of the maintenance platform, improving the stability of the support device. The locking connection method facilitates installation and disassembly, and anti-slip components of different materials or specifications can be replaced as needed to adapt to different working environments.

[0035] In a preferred embodiment, the stabilizing component is a wooden anti-slip component, and the ground surface of the wooden anti-slip component has a planar structure.

[0036] In a preferred embodiment, the connecting member is a sleeve 3. The first lead screw 2 and the second lead screw have opposite rotation directions. Rotating the sleeve 3 allows the first support 1 and the second support 4, and the second lead screw 5, to move closer or further apart. The sleeve 3, acting as a connecting member, connects the first and second supports. Rotating the sleeve 3 allows for simultaneous adjustment of the height of both supports, making operation simple and convenient. The design of the first and second lead screws having opposite rotation directions makes adjustment more efficient, enabling rapid installation and disassembly of the support device and improving work efficiency.

[0037] In a preferred embodiment, intelligent monitoring devices such as pressure sensors or displacement sensors are installed on the support device to monitor the stress and displacement changes of the support device in real time. By connecting to the control system, abnormal conditions of the support device can be detected promptly, and an alarm can be issued to remind staff to make adjustments or take appropriate safety measures.

[0038] This utility model also provides a method for using the inclined track maintenance support device as described in any of the above claims, characterized by including the following steps;

[0039] I. Preparatory Work

[0040] Check that all components of the ramp maintenance support device are intact, including the buffer (wooden mold), the first support (first support seat 1 and first lead screw 2), the connector (sleeve 3), the second support (second support seat 4 and second lead screw 5), and the stabilizer (wooden anti-slip component).

[0041] The number of inclined quenching chute inlets and their specific conditions shall be determined to determine the number of inclined chute maintenance support devices required.

[0042] II. Installation Process

[0043] Place the wooden mold below the ramp arch, ensuring that the curved part at the top matches the curvature of the ramp arch.

[0044] Align the first snap-fit ​​groove of the first support seat 1 with the bottom of the wooden mold and snap-fit ​​connection.

[0045] Align the first screw hole of the sleeve 3 with the first lead screw 2, rotate the sleeve 3 so that the first lead screw 2 is gradually screwed into the first screw hole, adjust the height of the first support seat 1 until the first support seat 1 presses the wooden mold against the arch of the inclined passage, but be careful not to tighten it too much to avoid pressure damage to the refractory material of the inclined passage.

[0046] Place the wooden anti-slip parts on the upper part of the support beam of the maintenance platform, choosing a suitable position.

[0047] Align the second locking groove of the second support base 4, the second lead screw 5 with the top of the wooden anti-slip part and make a locking connection.

[0048] Align the second screw hole of sleeve 3 with the second lead screw, rotate sleeve 3 to gradually screw the second lead screw into the second screw hole, adjust the height of the second support seat 4 and the second lead screw 5 until the wooden anti-slip parts of the second support seat 4 and the second lead screw 5 are pressed against the support beam of the maintenance platform to ensure that the entire support device is stable and reliable.

[0049] Based on the actual site conditions, check the stability of each support device. If necessary, add more wooden anti-slip parts or adjust their positions between the bottom of the second support seat 4, the second lead screw 5 and the support beam of the maintenance platform to prevent slippage.

[0050] III. Adjustments during use

[0051] If the support force of the support device is found to be unsuitable during use, it can be adjusted in the following ways:

[0052] If the support is too loose, continue to rotate sleeve 3 to bring the first support seat 1 and the second support seat 4 and the second lead screw 5 closer together, increasing the pressure on the ramp arch and the maintenance platform support beam, and improving the support strength.

[0053] If the support is too tight, rotate the sleeve 3 in the opposite direction to move the first support seat 1 and the second support seat 4 and the second screw 5 away from each other, thereby reducing the pressure on the inclined tunnel arch and the maintenance platform support beam and avoiding damage to the refractory material.

[0054] IV. Disassembly Process

[0055] After the maintenance work is completed, rotate the sleeve 3 in the opposite direction to move the first support seat 1 and the second support seat 4 and the second lead screw 5 away from each other, thereby reducing the pressure on the ramp arch and the maintenance platform support beam.

[0056] First, separate the second support seat 4, the second lead screw 5 from the wooden anti-slip parts, and then remove the wooden anti-slip parts from the upper part of the support beam of the maintenance platform.

[0057] Rotate the sleeve 3 in the opposite direction to make the first lead screw 2 unscrew from the first screw hole of the sleeve 3, thus separating the first support seat 1 from the wooden mold.

[0058] Finally, the wooden mold was removed from under the arch of the ramp entrance, completing the dismantling of the ramp maintenance support device.

[0059] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
