Description

Technical Field

[0001] The present invention relates to the technical field of metallurgical industry, and more particularly to a coke oven hole cleaning device and a tamping smoke guide vehicle and oven airing system used therein. Background Art

[0002] Coke ovens are divided into ramming coke ovens (also known as side-loaded coal coke ovens) and top-loaded coal coke ovens. For side-loaded coal coke ovens, during the coking process, due to the large temperature difference in the smoke guide hole area, rapid cooling and heating are more likely to occur. The repeated alternation of high and low temperatures leads to the continuous formation of graphite accumulation inside the smoke guide hole.

[0003] At present, the cleaning of graphite in the smoke guide hole mainly relies on manual cleaning with a steel chisel. The main problems with the smoke guide hole cleaning operation are as follows: (1) If the smoke guide hole is not cleaned in time, the graphite accumulated inside the smoke guide hole will become harder and harder, making it difficult to clean. At the same time, the diameter of the smoke guide hole will become smaller. Therefore, the smoke guide hole cleaning work must be carried out regularly and normally; (2) The frequency of manual cleaning is high and the labor intensity is high. The smoke guide hole is located at the top of the coke oven, and the ambient temperature in this area is relatively high. When the cleaning operation is carried out, the hole cover of the smoke guide hole is opened, and smoke, dust and flames are continuously ejected from the carbonization chamber. During the cleaning operation, the personnel are close to the coal loading port. The operators are exposed to safety hazards such as burns, scalds, gas poisoning, and high dust; (3) Refractory materials are cast inside the smoke guide hole. When cleaning manually with a steel chisel, there is no fixed cleaning trajectory and method. Cleaning solely based on personal experience can easily damage the refractory material. In the long run, this will affect the service life of the entire coke oven. (4) Manual cleaning of the smoke guide hole takes a long time. When the smoke guide hole cover is open, smoke, dust, and flames are constantly ejected from the smoke guide hole inside the carbonization chamber. This has a certain impact on the surrounding environment and increases the pressure on environmental protection work.

[0004] For top-loading coal coke ovens, during operation, the coal loading holes continuously repeat a series of work processes such as loading coal and discharging coke. The coal loading holes also have the above-mentioned technical problem of difficulty in cleaning graphite carbon deposits.

[0005] Existing research has explored automated cleaning of smoke guide holes or top coal loading holes, and has designed some automated cleaning devices. For example, Chinese patent application number CN 218596308 U discloses an electric rotary graphite cleaning device for coke oven coal loading holes, comprising a cleaning rod with a mounting flange fixed to its end, and a drive mechanism for rotating the cleaning rod, the drive mechanism comprising a motor, a transmission disc, and a mounting seat; a rotating shaft rotatably connected to the mounting seat via a bearing, a driven gear mounted on the end of the rotating shaft; the rotating shaft and the mounting flange are detachably connected; a motor is mounted on the transmission disc, which has a through hole for the driven gear to pass through; a reduction gear set rotatably connected to the transmission disc, the reduction gear at the input end of the reduction gear set being connected to the power output shaft of the motor; a reduction gear at the output end of the reduction gear set meshing with the driven gear; and a connecting flange is provided on the mounting seat. While this application enables automatic cleaning of the top coal-loading hole, its cleaning trajectory is a cylindrical curved surface centered on the cleaning rod. When carbon deposits on the inner wall of the top coal-loading hole or smoke-guiding hole cause the diameter to change along its circumference, especially when there is a localized area of severe carbon deposits on the inner wall of the coal-loading hole, where the inner diameter decreases, the resistance between the cleaning rod and the coal-loading hole is excessive, affecting normal cleaning and easily damaging the refractory material. More importantly, when the cleaning rod moves downward to the top coal-loading hole, the relative position between the cleaning rod and the top coal-loading hole is highly demanding.

[0006] For example, the Chinese patent application with publication number CN 117165309 A discloses an intelligent device for sealing the coal charging hole on the furnace roof, in which the lid lifter and the coal charging hole cleaning machine have a floating adjustment function in the horizontal direction. When the lid lifter moves downward and contacts the furnace cover with deviation in alignment, the conical hole on the electromagnet contacts the vertebral body on the furnace cover, causing the three lid lifter buffer springs evenly distributed between the lid lifter cylinder and the lid lifter pressure barrel to be compressed, so that the three lid lifter positioning booms evenly distributed around the lid lifter cylinder move upward and create a gap between them and the lid lifter pressure barrel. Because the lid rolling head installed on the top of the lid lifter buffer spring is equipped with a universal ball bearing, the lid lifter cylinder moves in the direction of the furnace cover deviation, thereby compensating for the error. When the lid lifter lifts the furnace cover and moves upward, the lid lifter positioning boom automatically slides into the conical hole of the lid lifter pressure barrel to achieve automatic reset, which can compensate for the ±40mm error of the coal charging hole seat in the horizontal direction. The mechanical structure used in the coal-loading hole cleaning machine for automatic error handling and reset is similar to that of the cover lifter. While this application reduces the relative positioning requirements between the coal-loading hole cleaning machine and the top coal-loading hole, its relatively complex structure still cannot address the problem of circumferential changes in the diameter of the top coal-loading hole or smoke-guiding hole caused by carbon deposits.

[0007] Existing coke oven hole cleaning devices are unable to adapt to the problem that the diameter of the top coal loading hole or the smoke guide hole changes along the circumferential direction due to carbon deposition on the inner wall thereof. Summary of the Invention

[0010] Furthermore, one end of the cleaning connection piece is rotatably mounted on the turntable. When the turntable rotates, the cleaning connection piece is acted upon by centrifugal force, and its free end rotates upward around the end connected to the turntable; or one end of the cleaning connection piece is telescopically mounted on the turntable along its own axis, and is inclined relative to the axis of the turntable. When the turntable rotates, the cleaning connection piece is acted upon by centrifugal force, and the distance between its free end and the turntable increases.

[0030] This embodiment provides a coke oven hole cleaning device, referring to Figure 1-Figure 3As shown, the furnace hole cleaning device includes a cleaning mounting frame 1, a first telescopic driving member 2, a cleaning driving mechanism 4 and a cleaning head assembly 7. The first telescopic driving member 2 and the cleaning driving mechanism 4 are both installed on the cleaning mounting frame 1. The first telescopic driving member 2 is used to drive the cleaning head assembly 7 to move in the vertical direction, and the cleaning driving mechanism 4 is used to drive the cleaning head assembly 7 to rotate around the vertical direction; the cleaning head assembly 7 includes a turntable 705, a cleaning connecting member and a cleaning brush head, one end of the cleaning connecting member is installed on the turntable 705, and the other end is a free end and a cleaning brush head is provided at the end; when the turntable 705 rotates, the cleaning connecting member is subjected to centrifugal force, and the radial distance between its free end and the center of the turntable 705 increases, so as to contact the inner wall of the smoke guide hole and clean the inner wall of the smoke guide hole.

[0031] In some embodiments, one end of the cleaning connector is rotatably mounted on the turntable 705. When the turntable 705 rotates, the cleaning connector is acted upon by centrifugal force, and its free end rotates upward around the end connected to the turntable 705.

[0032] It should be noted that one end of the cleaning connector is rotatably mounted on the turntable 705, wherein the rotatable mounting includes one end of the cleaning connector being limitedly mounted on the turntable 705 by means of a buckle, a rotating shaft, a limit pin, etc., so that the end cannot escape the restraint of the turntable 705, and the other end can rotate relative to the end, which has a wider range than traditional rotatable mounting. The cleaning connector will naturally droop under the influence of gravity. When the turntable 705 rotates, the cleaning connector is acted upon by centrifugal force, and its free end rotates upward around its other end, thereby moving its free end away from the turntable 705, reducing the distance between the free end and the inner wall of the smoke guide hole and contacting it to clean the inner wall of the smoke guide hole.

[0033] In other embodiments, one end of the cleaning connector is retractably mounted on the turntable 705 along its own axis and is tilted relative to the axis of the turntable 705. When the turntable 705 rotates, the cleaning connector is subjected to centrifugal force, increasing the distance between its free end and the turntable 705. The turntable 705 is provided with a slideway inside, and a tension spring can be disposed within the slideway. One end of the tension spring is placed inside the turntable 705, and the other end is fixedly connected to the cleaning connector. When the turntable 705 is stationary, the tension spring retracts, causing the cleaning connector to return to its original position.

[0034] It should be noted that one end of the cleaning connector can be retractably mounted on the turntable 705 along its own axis, and can also be implemented in the following form: the cleaning connector includes a coaxially arranged fixed end and a movable end, the movable end can be retracted along its axial direction relative to the fixed end to adjust the distance between the two, the fixed end is fixedly connected to the turntable 705, and the fixed end and the movable end are connected by a spring. When the turntable 705 rotates, the movable end moves away from the fixed end along its axial direction, and the distance between the movable end and the inner wall of the smoke guide hole is reduced and contacts with it to clean the inner wall of the smoke guide hole. When the turntable 705 is stationary, the spring retracts, causing the movable end of the cleaning connector to return to its position.

[0035] As a preferred embodiment of the cleaning connecting member, the cleaning connecting member is a chain 702, and the outer ring of the turntable 705 is also provided with a plurality of chain connecting buckles 701 evenly spaced along its circumferential direction, and each chain connecting buckle 701 is correspondingly provided with a chain 702, and the other end of the chain 702 away from the turntable 705 is provided with a wire brush head 703; the cleaning drive mechanism 4 is installed at the telescopic end of the first telescopic drive member 2, and is used to drive the cleaning drive mechanism 4 to move in the vertical direction, and the first telescopic drive member 2 drives the cleaning head assembly 7 to move in the vertical direction through the cleaning drive mechanism 4, and the turntable 705 is installed at the rotation output end of the cleaning drive mechanism 4; the cleaning drive mechanism 4 is used to drive the turntable 705 to rotate around the vertical direction.

[0036] refer to Figure 5 As shown, the cleaning principle of the cleaning head assembly 7 is as follows: when the turntable 705 does not rotate, the chain 702 is naturally suspended by gravity, as shown in FIG. Figure 5 When the rotation speed of the turntable 705 reaches a certain value, the reference Figure 5 Taking the perspective shown as an example, the end of the chain 702 away from the turntable 705 rotates upward, gradually changing from the state indicated by B to the state indicated by A. The present invention uses the turntable 705 to drive the chain 702 to rotate, and the end of the chain 702 away from the turntable 705 rotates upward. When it descends to the inner wall of the smoke guide hole, the distance between the chain 702 and the inner wall of the smoke guide hole gradually decreases and contacts, thereby cleaning the inner wall of the smoke guide hole.

[0037] The cleaning head assembly 7 in the furnace hole cleaning device of the present invention uses a chain 702 as a mounting carrier for the wire brush head 703, which can achieve flexible adjustment of the spacing between the wire brush head 703 used for cleaning and the inner wall of the smoke guide hole seat. When the contact force between the wire brush head 703 and the inner wall of the smoke guide hole seat is too large, the chain 702 will automatically adjust the relative distance between multiple chain links, so as to adapt to the top coal loading hole or the inner wall of the smoke guide hole along its circumferential direction. The diameter changes caused by carbon deposition, thereby preventing the dead angle produced when the inner wall of the smoke hole seat is cleaned. Moreover, because the distance between the chain 702 in the cleaning head assembly 7 and the inner wall of the smoke guide hole seat can be flexibly adjusted, when the cleaning head assembly 7 descends to the inner wall of the smoke guide hole, the relative position requirements of the axis of the turntable 705 in the cleaning head assembly 7 and the axis of the smoke guide hole are relatively low. Existing coke oven cleaning devices have high requirements for the coaxiality between their central axis and the cleaned hole wall, especially the device that performs linear scraping and cleaning of the inner wall of the smoke guide hole seat in the vertical direction. In addition, it effectively avoids excessive cleaning force on the hole wall.

[0038] The specific cleaning process of the furnace hole cleaning device is as follows: the first telescopic drive member 2 drives the cleaning movable frame 3 and its upper components to descend to a certain depth inside the smoke guide hole seat. At this time, the multiple chains 702 arranged at intervals along the circumference of the turntable 705 all have a large gap with the inner wall of the smoke guide hole seat along their circumferential direction. The cleaning drive mechanism 4 drives the cleaning head assembly 7, which in turn drives the turntable 705 to rotate. The gap between the end of the chain 702 away from the turntable 705 and the inner wall of the smoke guide hole seat gradually decreases, and the wire brush head 703 contacts the inner wall of the smoke guide hole seat to clean the inner wall of the smoke guide hole seat. The first telescopic drive member 2 drives the cleaning movable frame 3 to move relative to the inner wall of the smoke guide hole seat along its axis, thereby completing the cleaning of the inner wall of the smoke guide hole seat at different heights.

[0039] Specifically, the wire brush head 703 has an open end, which is sleeved onto the end of the chain 702 away from the turntable through the open end. More specifically, the wire brush head 703 is sleeved into the link holes of the chain 702 through the open end. The open end of the wire brush head 703 is provided with a limit buckle 704 sleeved on the outside to prevent the wire brush head 703 from falling out of the link holes of the chain 702. The connection between the wire brush head 703 and the link holes of the chain 702 adopts this method to facilitate the replacement of the wire brush head 703. Preferably, the wire brush head 703 can adopt an existing steel chisel cleaning brush head.

[0040] It should be noted that the connection relationship between the wire brush head 703 and the chain 702 is not limited to the above structure, and a variety of connection methods can be used, such as the wire brush head 703 is fixedly connected to the chain link at the end of the chain 702 away from the turntable 705.

[0042] Specifically, in order to reduce the swing of the cleaning spindle away from the bottom end of the cleaning movable frame 3 when it rotates, the furnace hole cleaning device also includes a cleaning head connecting rod 6 that is sleeved on the outside of the cleaning spindle 8. The top end of the cleaning head connecting rod 6 is fixedly connected to the cleaning movable frame 3, and a bearing is installed inside the bottom end to support the rotation of the cleaning spindle 8.

[0043] In order to improve the stability of the cleaning movable frame 3 in sliding relative to the cleaning mounting frame 1, a cleaning telescopic guide assembly 5 is provided between the cleaning head connecting rod 6 and the cleaning mounting frame 1. The cleaning telescopic guide assembly 5 is used to guide the movement of the cleaning movable frame 3 in the vertical direction. Preferably, a cleaning telescopic guide assembly 5 is provided between both sides of the cleaning head connecting rod 6 and the cleaning mounting frame 1.

[0044] Among them, the cleaning telescopic guide assembly 5 can adopt a slider rail assembly or other existing guide mechanisms, such as a pressure wheel guide mechanism, etc., and its specific structure will not be repeated here.

[0045] More specifically, refer to Figure 4 As shown, the cleaning drive mechanism 4 includes a rotary motor 401 and a transmission assembly 402. The cleaning movable frame 3 is a hollow structure, and the transmission assembly 402 is located inside the cleaning movable frame 3. The rotary motor 401 is installed at the bottom end of the cleaning movable frame 3 and passes through the cleaning movable frame 3 and is connected to the transmission assembly 402. The rotary motor 401 drives the cleaning head assembly 7 to rotate in the vertical direction through the transmission assembly 402. This arrangement is conducive to reducing the height of the cleaning movable frame 3.
