Description

Technical Field

[0001] This invention belongs to the field of coking technology, specifically relating to a coal charging bottom plate cleaning device and its cleaning method. Background Technology

[0002] Currently, after coal is loaded into the coke oven vehicle, residual coal dust on the bottom plate surface is crushed by the rear baffle wheels as the rear baffle device retracts, causing the vehicle to tilt and its running trajectory to become unstable. Consequently, it cannot accurately reach the preset "rear limit lock" position, resulting in mechanical lock failure. After lock failure, the equipment interlocking logic cannot be triggered, automatic operation fails, and operators must manually clean the accumulated coal on the bottom plate surface after each coal loading cycle, increasing labor intensity and working time, and preventing fully automated operation. Furthermore, during the subsequent tamping process, malfunctioning tamping hammers can easily strike rear baffles that are not properly locked, causing serious accidents such as severe bending and damage to the equipment. Summary of the Invention

[0003] In view of the above problems, the purpose of this invention is to provide a coal loading bottom plate cleaning device and its cleaning method, which solves the problem that existing devices cannot automatically clean the coal accumulation on the bottom plate surface.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows: A coal loading floor cleaning device is used for a rear baffle device. The rear baffle structure includes a rear baffle structure, a coal loading floor, and a traveling structure. The traveling structure is provided on the coal loading floor. The rear baffle structure is connected to the traveling structure and includes a support unit, a cleaning unit, and a purging unit. The support unit is located on both sides of the traveling structure. The cleaning unit is located on the side of the support unit closer to the coal loading floor. The purging unit is located on the upper side of the coal loading floor. The support unit moves axially along the coal loading floor with the traveling structure. The cleaning unit contacts the surface of the coal loading floor for mechanical cleaning. The purging unit cooperates with the cleaning unit to complete secondary purging and cleaning of accumulated coal.

[0005] In some embodiments, the purging unit includes an airflow channel and a purging assembly, the purging assembly communicating with the airflow channel, the airflow channel being located above the coal charging floor, and the purging assembly corresponding to the surface of the coal charging floor.

[0006] In some embodiments, the cleaning unit includes a cleaning component and a connecting component connected to the cleaning component, wherein the cleaning component is connected to the support unit via the connecting component.

[0007] In some embodiments, the support unit is located below and connected to the rear baffle structure, and the support unit moves along the axial direction of the coal loading bottom plate with the traveling structure.

[0008] In some embodiments, the purging components are configured as a plurality, each of which communicates with the airflow channel.

[0009] In some embodiments, the connecting component is 10-20 cm away from the coal loading floor.

[0010] In some embodiments, the lower side of the cleaning assembly is in contact with the surface of the coal loading base plate.

[0011] In some embodiments, the purging assembly is 10-30 cm away from the coal charging floor.

[0012] In some embodiments, the purging unit further includes a control component connected to both the airflow channel and the purging component.

[0013] The technical solution of this invention is implemented as follows: A method for cleaning the bottom plate of a coal loading station, using the aforementioned coal loading station cleaning device, includes the following steps: The walking structure moves on the coal loading base plate, and the cleaning unit moves with the walking structure to clean the accumulated coal on the coal loading base plate; When the walking structure moves to the tail of the coal loading floor, if the cleaning unit has not cleaned the coal on the coal loading floor, the blowing unit is activated to clean the coal loading floor; if the cleaning unit has cleaned the coal on the coal loading floor, the blowing unit is not activated.

[0014] Compared with the prior art, when the cleaning device of the present invention is used on the rear baffle device, as the traveling mechanism moves along the axial direction of the coal loading bottom plate, the support unit protects the traveling mechanism to prevent coal from entering the traveling mechanism. The cleaning unit contacts the surface of the coal loading bottom plate and moves with the traveling structure to achieve mechanical cleaning of the coal. The blowing unit cooperates with the cleaning unit to complete the secondary blowing and cleaning of the coal, achieving thorough cleaning of the coal on the coal loading bottom plate. After adopting this device, manual cleaning of the coal on the bottom plate surface is not required, reducing manual labor time and the risk of accidents. At the same time, the equipment is protected and its service life is increased. Attached Figure Description

[0026] Example 1 A coal loading floor cleaning device, such as Figure 1 As shown, a rear baffle device 2 is used. The rear baffle structure 21 includes a rear baffle structure 21, a coal loading base plate 22, and a traveling structure 23. The traveling mechanism is provided on the coal loading base plate 22. The rear baffle structure 21 is connected to the traveling structure 23 and includes a support unit 11, a cleaning unit 12, and a blowing unit 13. The support unit 11 is located on both sides of the traveling structure 23. The cleaning unit 12 is located on the side of the support unit 11 close to the coal loading base plate 22. The blowing unit 13 is located on the upper side of the coal loading base plate 22. The support unit 11 moves axially along the coal loading base plate 22 with the traveling structure 23. The cleaning unit 12 contacts the surface of the coal loading base plate 22 for mechanical cleaning. The blowing unit 13 cooperates with the cleaning unit 12 to complete the secondary blowing and cleaning of accumulated coal.

[0027] After adopting the above scheme, when the cleaning device 1 is used on the rear baffle device 2, as the traveling mechanism moves along the axial direction of the coal loading bottom plate 22, the support unit 11 protects the traveling mechanism to prevent coal from entering the traveling mechanism. The cleaning unit 12 contacts the surface of the coal loading bottom plate 22 and moves with the traveling structure 23 to achieve mechanical cleaning of the coal. The blowing unit 13 cooperates with the cleaning unit 12 to complete the secondary blowing and cleaning of the coal, achieving thorough cleaning of the coal on the coal loading bottom plate 22 without dead angles. After adopting this device, there is no need for manual cleaning of the coal on the bottom plate surface, reducing manual labor time and the risk of accidents. At the same time, the equipment is protected and its service life is increased.

[0028] In the specific implementation process of Embodiment 1 of the present invention, such as Figure 2 As shown, the purging unit 13 includes an airflow channel 131 and a purging assembly 132. The purging assembly 132 communicates with the airflow channel 131, and the airflow channel 131 is located above the coal loading bottom plate 22. The purging assembly 132 corresponds to the surface of the coal loading bottom plate 22.

[0029] More specifically, gas is introduced into the airflow channel 131, and the gas is introduced into the purging assembly 132. The purging assembly 132 blows out gas to purge the purging surface, which is the surface of the coal loading bottom plate 22.

[0030] Furthermore, the gas in the airflow channel 131 is supplied by the vehicle compressor, and the airflow channel 131 is located in a fixed position and does not move after the baffle device 2; the airflow channel 131 is made of rigid metal pipe, which has good pressure resistance and sealing performance to prevent gas leakage.

[0031] In the specific implementation process of Embodiment 1 of the present invention, such as Figure 2 As shown, the cleaning unit 12 includes a cleaning component 121 and a connecting component 122 connected to the cleaning component 121. The cleaning component 121 is connected to the support unit 11 through the connecting component 122.

[0032] More specifically, the cleaning component 121 cleans the accumulated coal on the coal loading base plate 22. The cleaning component 121 is connected to the support unit 11 through the connecting component 122. The connecting component 122 is a metal connecting rod structure with sufficient structural strength to ensure that the cleaning component 121 does not deform during the moving cleaning process.

[0033] Furthermore, the cleaning unit 12 also includes a fastening assembly, through which the cleaning assembly 121 is connected to the connecting assembly 122. The fastening assembly is a high-strength bolt and nut mating structure, which facilitates the disassembly, replacement, and maintenance of the cleaning assembly 121.

[0034] Furthermore, the cleaning component 121 can be a baffle or a brush head with a certain strength. The cleaning component 121 can clean the accumulated coal on the surface of the coal loading base plate 22. The cleaning component 121 uses a wear-resistant rubber brush head, which ensures close contact with the surface of the coal loading base plate 22 without causing scratch damage to the surface of the base plate.

[0035] Furthermore, the lower part of the sweeping component 121 is made of a wear-resistant and strong material as the walking surface and sweeping surface.

[0036] In the specific implementation process of Embodiment 1 of the present invention, such as Figure 1As shown, the support unit 11 is located below the rear baffle structure 21 and connected to the rear baffle structure 21. The support unit 11 moves along the axial direction of the coal loading bottom plate 22 with the traveling structure 23.

[0037] More specifically, the support unit 11 protects the walking structure 23, preventing coal accumulated on the coal loading base plate 22 from entering the interior of the walking structure 23 during movement, and preventing granular or lumpy coal in the accumulated coal from affecting the movement of the walking structure 23. The support unit 11 is a protective plate structure made of metal sheet, which has good impact resistance.

[0038] Furthermore, one end of the support unit 11 is connected to the lower part of the rear baffle structure 21, and the other end of the support unit 11 has a gap of 10-50cm from the coal loading floor 22. The length of the support unit 11 is less than or equal to the diameter of the traveling structure 23. This gap ensures the protective effect of the support unit 11 while avoiding friction with the coal loading floor 22. The length of the support unit 11 being less than or equal to the diameter of the traveling structure 23 ensures full coverage protection for the support unit against the traveling structure 23.

[0039] Furthermore, the walking mechanism includes a first walking wheel 231 and a second walking wheel 232. Both the first walking wheel 231 and the second walking wheel 232 are located below the rear baffle structure 21, and both the first walking wheel 231 and the second walking wheel 232 move along the axial direction of the coal loading bottom plate 22. The support unit is correspondingly located on the outside of the first walking wheel 231 and the second walking wheel 232 to form double-sided protection.

[0040] In the specific implementation process of Embodiment 1 of the present invention, such as Figure 2 As shown, multiple purging components 132 are configured, and each purging component 132 communicates with the airflow channel 131.

[0041] More specifically, multiple purging components 132 are configured to purge various positions on the coal charging base plate 22, resulting in a cleaner removal of accumulated coal and eliminating any dead corners. The purging components 132 are linearly and evenly distributed below the airflow channel 131, with each component communicating with the airflow channel 131. The purging components 132 have a flat nozzle structure, increasing the purging area and improving purging efficiency.

[0042] In the specific implementation process of Embodiment 1 of the present invention, such as Figure 1 As shown, the distance between the connecting component 122 and the coal loading bottom plate 22 is 10-20cm.

[0043] More specifically, the distance between the connecting component 122 and the coal loading base plate 22 is 10-20cm, which facilitates the installation and adjustment of the cleaning component 121, while ensuring that the cleaning component 121 effectively cleans the coal accumulation on the surface of the coal loading base plate 22 and avoids interference between the connecting component 122 and the coal loading base plate 22.

[0044] In the specific implementation process of Embodiment 1 of the present invention, the distance between the purging component 132 and the coal charging bottom plate 22 is 10-30cm.

[0045] More specifically, this distance ensures both the strength of the sweeping wind and the maximum sweeping coverage.

[0046] In a specific implementation of Embodiment 1 of the present invention, the purging unit 13 further includes a control component 133, which is connected to both the airflow channel 131 and the purging component 132.

[0047] More specifically, the control component 133 is an electromagnetic control valve, which is installed on the main pipeline of the airflow channel 131. It can be remotely controlled through the central control system of coke oven production, or manually controlled on site to realize the start and stop of the purging unit 13 and the air volume adjustment.

[0048] Furthermore, a sensor is provided at the tail end of the coal charging bottom plate 22 to detect the residual coal accumulation on the surface of the coal charging bottom plate 22 and is connected to the control component 133. The sensor can be an infrared sensor capable of sensing coal slag, or it can be any other component capable of sensing coal slag.

[0049] The workflow of Embodiment 1 of the present invention is as follows: The coal loading bottom plate cleaning device of the present invention is linked with the walking structure 23 of the rear baffle device 2. When the walking structure 23 moves backward, the support unit 11 moves synchronously with it, forming double-sided protection for the walking wheels to prevent coal accumulation from entering the walking structure 23 and causing jamming and wear. At the same time, the cleaning component 121 connected to the support unit 11 contacts the surface of the coal loading bottom plate 22 and completes the mechanical scraping of the coal accumulation during the movement, pushing most of the coal accumulation to the designated collection area. Before the walking structure 23 moves to the rear limit locking position, the detection device judges the residual coal accumulation on the bottom plate. If there is any residue, the blowing unit 13 is activated. The compressed gas supplied by the compressor is used to blow the residual coal accumulation under high pressure through multiple blowing components 132 to achieve secondary cleaning and ensure that there is no coal accumulation residue on the bottom plate. If the coal accumulation has been cleaned, the blowing unit 13 is not activated to save energy. The entire cleaning process requires no manual operation and is compatible with the automated process of coke oven coal charging, ensuring that the rear baffle device 2 accurately achieves rear limit locking, triggers equipment interlocking logic, and avoids equipment accidents.

[0050] Example 2 A method for cleaning the bottom plate of a coal loading station, using the coal loading station cleaning device as described in Example 1, includes the following steps: The walking structure 23 moves backward along the axial direction on the coal loading base plate 22. The cleaning unit 12, which is linked with the walking structure 23, moves synchronously with the walking structure 23. The cleaning component 121 is in close contact with the surface of the coal loading base plate 22. During the movement, it scrapes and pushes most of the accumulated coal on the coal loading base plate 22 to the tail collection area of ​​the coal loading base plate 22, thus completing the mechanical cleaning. When the walking structure 23 moves to 50cm before the rear limit locking position of the coal loading bottom plate 22, the infrared detection sensor on the coal loading bottom plate 22 detects the residual coal on the bottom plate surface to determine whether the cleaning unit 12 has cleaned the coal on the coal loading bottom plate 22. If residual coal is detected, the sensor transmits a signal to the control component 133, and the control component 133 starts the blowing unit 13. The compressed gas in the airflow channel 131 blows the surface of the coal loading bottom plate 22 under high pressure through multiple blowing components 132, blowing the residual coal to the collection area to complete the secondary cleaning. If the coal on the coal loading bottom plate 22 is detected to be cleaned, the sensor does not output a signal, and the control component 133 does not start the blowing unit 13.

[0051] In this embodiment 2, the infrared detection sensor is linked with the coke oven central control system to realize automated control of detection and purging without manual intervention, further improving the automation level of the coal charging process.
