Description

Technical Field

[0001] The utility model relates to the technical field of electric calciners, in particular to a device for cleaning coke deposits on the inner wall of an electric calciner. Background Art

[0002] At present, due to the characteristics of coal quality, slagging and coking are very likely to occur in the furnace during the normal production process of electric calciners when the thermal parameters such as boiler volumetric heat load, cross-sectional heat load and wall heat load remain unchanged.

[0003] Furnace slagging and coking refer to the phenomenon in which ash melts at high temperatures and adheres to the water-cooled walls or the screen at the furnace outlet. Furnace coking or slagging is the result of a combination of factors, such as the melting characteristics of the coal ash, excessive heat load on the furnace section, poor aerodynamic field, and flame adhesion to the wall. Ash particles are molten at high temperatures. If they fail to cool into solid particles before reaching the heated surface of the furnace, the molten ash particles will adhere to the heated surface, forming coke or slagging. When coke or slagging forms, the heat absorption of the heated surface decreases, and the cooling capacity is reduced, causing the temperature near the heated surface to rise, exacerbating coking and slagging. Furnace coking and slagging problems cause current deviation in the furnace, resulting in overburning, uneven discharge, increased energy consumption, and the induction of blasting furnaces.

[0004] To address the problem of coking and slagging in the furnace, usually only 2-3 workers can work together to clean the slag and coke in the furnace once every two months using a long steel pipe with a drill. During this process, due to the high intensity of manual slagging removal, a group of workers must be replaced every 20 minutes or so, resulting in increased staffing and additional manpower consumption. In addition, the efficiency of manual slagging removal is also low. Usually, several groups of workers need 2-3 days to complete the furnace coking and slagging cleaning operation.

[0025] Please see Figures 1 to 3 The utility model provides a coke cleaning device for the inner wall of an electric calcining furnace, comprising a support frame 01 and a cleaning mechanism 02;

[0026] The cleaning mechanism 02 includes a conduit 21 and a cleaning rod 22; the conduit 21 is hinged on the support frame 01 so that the conduit 21 can adjust the angle between the conduit 21 and the vertical direction of the support frame 01 along the longitudinal direction of the support frame 01, the cleaning rod 22 is inserted along the conduit 21 and passes through the entire conduit 21, and the cleaning rod 22 can move back and forth along the conduit 21, and a power unit 23 is installed at one end of the cleaning rod 22 to drive the cleaning rod 22 through the power unit 23 to achieve coke cleaning. The power unit 23 can be a handheld vibration motor or a handheld drive motor. When in use, the worker can operate the power unit 23 and use the power unit 23 to drive the cleaning rod 22 to achieve coke cleaning on the inner wall of the electric calciner. During the operation, the angle of the cleaning rod 22 can be adjusted by adjusting the angle of the conduit 21, so as to facilitate cleaning of different positions of the inner wall of the electric calciner; during the entire operation, only one person is required to operate, and the other person cooperates to observe the furnace, which greatly reduces personnel consumption and reduces the intensity of manual labor. The guide tube 21 can not only adjust the angle of the cleaning rod 22, but also support the cleaning rod 22 to reduce the burden on workers, thereby improving cleaning efficiency.

[0027] In one embodiment, the support frame 01 is further provided with an adjustment mechanism 03 , one end of which is connected to the conduit 21 , so that the angle between the conduit 21 and the support frame 01 in the vertical direction can be adjusted through the adjustment mechanism 03 .

[0028] Of course, the length of the conduit 21 can be selected according to the requirements of use; when the length of the conduit 21 is sufficient, the conduit 21 can be extended into the electric forging furnace so that the conduit 21 is against the edge of the furnace mouth of the electric forging furnace. At this time, the angle formed by the conduit 21 can be positioned by the adjustment mechanism 03, and the conduit 21 can be pressed tightly against the furnace mouth of the electric forging furnace; when a handheld vibration motor is selected using the power unit 23, the vibration of the conduit 21 can be reduced.

[0029] To be specific, the adjustment mechanism 03 includes a first connection end 31, a second connection end 32, and an adjustment rod 33; the first connection end 31 is hinged to the catheter 21, the second connection end 32 is hinged to the support frame 01, one end of the adjustment rod 33 is rotated and connected to the first connection end 31, and the other end of the adjustment rod 33 is threadedly connected to the second connection end 32. When the adjustment rod 33 rotates, the angle between the catheter 21 and the support frame 01 in the vertical direction can be adjusted.

[0030] In order to facilitate the rotation of the adjusting rod 33 and facilitate the use of workers, a hand wheel 34 is fixedly provided on the adjusting rod 33 to drive the adjusting rod 33 to rotate.

[0031] In one embodiment, to facilitate movement, a mobile trolley 04 is provided below the support frame 01. Rollers with a self-locking function are installed below the mobile trolley 04, so that when in use, the self-locking function of the rollers can be used to limit the displacement of the mobile trolley 04 and prevent the mobile trolley 04 from moving during operation.

[0032] In one embodiment, the support frame 01 includes a left frame body 11 and a right frame body 12; the left frame body 11 and the right frame body 12 are fixed opposite to each other on the mobile trolley 04, and a first cross bar 13 and a second cross bar 14 are arranged between the left frame body 11 and the right frame body 12 from top to bottom. The first cross bar 13 is hinged to the conduit 21, and the second cross bar 14 is connected to the second connecting end 32.

[0033] Specifically, a connecting plate 15 is provided on the left frame 11 and the right frame 12, and a limiting hole is opened on the connecting plate 15. The two ends of the first cross bar 13 and the second cross bar 14 are respectively provided with positioning holes, and pins are inserted into the limiting holes and the positioning holes.

[0034] In one embodiment, a cleaning portion 05 is mounted on an end of the cleaning rod 22 away from the driving portion.

[0035] To be specific, the cleaning part 05 includes a base plate 51, and a hinged joint for connecting the cleaning rod 22 is provided on one side surface of the base plate 51. The minimum angle formed between the base plate 51 and the cleaning rod 22 is 75°, and scraping columns 52 are evenly distributed on the side surface of the base plate 51 opposite to the hinged joint.

[0036] The shape of the base plate 51 may be a diamond structure, so that the cleaned slag can fall along the oblique edge of the base plate 51, thereby reducing cleaning resistance.

[0037] The end of the scraping column 52 is tapered so that the coke formed into large blocks can be broken up by the scraping column 52, thereby improving the cleaning efficiency.

[0038] There are two ways to perform the cleaning operation. One of them is that the power unit 23 uses a handheld vibration motor. At this time, the power unit 23 can drive the cleaning rod 22 to vibrate axially, so that the cleaning unit 05 contacts the coke on the inner wall of the furnace, and the vibration of the scraper column 52 can be used to break the coke. After completing the operation, the power unit 23 can be replaced with a drive motor, and the power unit 23 is used to drive the cleaning rod 22 to rotate, so that the cleaning unit 05 contacts the coke on the inner wall of the furnace, and then the cleaning unit 05 forms rotational friction on the inner wall of the furnace, and then the scraper column 52 is used to scrape off small pieces of coke to complete the cleaning operation.

[0039] The above disclosure is only a preferred embodiment of the present invention, and it is certainly not intended to limit the scope of the rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the present invention.
