Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of carbon anode production, and particularly relates to a carbon bowl scraping tool alignment method and a carbon bowl cleaning device. BACKGROUND

[0002] After the aluminum electrolysis pre-baked anode carbon block is fired, a part of coke particles will be adhered to the surface of the anode carbon block, which needs to be removed and cleaned. When the coke is cleaned, the four side surfaces, four inclined surfaces, one top surface, one bottom surface and the carbon bowl on the top surface of the anode baked carbon block need to be cleaned. The carbon bowl is a plurality of pits arranged on the top surface of the carbon block for connecting the conductive part.

[0003] In the prior art, there are rotating scraper methods for cleaning the carbon bowl, such as the Chinese patent document “Pre-baked anode carbon bowl cleaning device” with the publication number CN217251370U. The scraper needs to be accurately aligned with the carbon bowl, and the gap between the scraper and the side wall of the carbon bowl is very small. Therefore, the alignment matching between the axis of the scraper and the axis of the carbon bowl is very important, otherwise the high-speed rotating scraper is easy to damage the carbon bowl. In order to protect the carbon bowl, a relatively soft scraping method is adopted, such as a steel brush composed of steel wires, as shown in the Chinese patent document “Anode carbon block carbon bowl cleaning device” with the publication number CN217342703U. Although the scraping method of this kind of device is relatively soft, the carbon bowl axis needs to be aligned so that the steel brush coincides with the carbon bowl axis, otherwise the cleaning effect will be affected. Therefore, in order to ensure the cleaning effect of the carbon bowl and protect the carbon bowl, it is necessary to accurately align the carbon bowl with the scraping tool through the mechanical device.

[0024] Embodiment 1: Please refer to Figure 1 ;

[0025] The application provides the following technical solutions: a carbon bowl cleaning device, comprising a wind volume sensor 1 and a scraping tool for cleaning the inside of the carbon bowl, and a carbon bowl scraping tool alignment method when in use.

[0026] The carbon bowl scraping tool alignment method comprises uniformly blowing air into the carbon bowl; arranging multiple wind volume sensors 1 at the carbon bowl opening in a circumferential and uniform manner based on the axis of the scraping tool; obtaining wind volume values overflowing from the carbon bowl through the wind volume sensors 1; adjusting the position of the scraping tool until the multiple wind volume values are consistent, indicating that the scraping tool is coaxial with the carbon bowl axis, and the alignment is completed.

[0027] The principle is that when uniformly blowing air into the carbon bowl, the carbon bowl is a blind hole, and the gas overflows; since the wind volume sensor 1 is coaxial with the scraping tool, when the scraping tool is coaxial with the carbon bowl axis, the wind volume along the circumferential direction of the carbon bowl should be uniform, so when the multiple wind volume values are consistent, the alignment is completed.

[0028] In order to uniformly blow air into the carbon bowl and detect the wind volume, the multiple wind volume sensors 1 of the carbon bowl cleaning device are arranged in the air blowing sleeve 20 in a circumferential and uniform manner; the air blowing sleeve 20 is coaxially sleeved outside the scraping tool, and an air passage 202 is arranged in the air blowing sleeve 20, and an air blowing port 201 is arranged at the end of the air passage 202, which is used for uniformly blowing air into the carbon bowl. Therefore, air blowing and wind detection are both completed by the air blowing sleeve 20.

[0029] For example, the air blowing sleeve 20, the center of which is provided with a shaft hole 203, is slidably and coaxially sleeved outside the transmission shaft 23 of the scraping tool, and one end of the air blowing sleeve 20 is provided with a tapered protruding portion 204; the small end of the tapered protruding portion 204 faces the carbon bowl, and a plurality of air blowing ports 201 are arranged on the outer surface of the tapered protruding portion 204 in a circumferential and uniform manner to ensure uniform air blowing; the air blowing ports 201 are in communication with the air passage 202 in the air blowing sleeve 20, the air passage 202 is in communication with a gas collecting ring 205, and the gas collecting ring 204 is fixedly arranged on the end face of the air blowing sleeve 20 and is provided with an air source interface 206;

[0030] The air blowing sleeve 20 is provided with multiple circumferential and uniform wind measuring ports 207; the wind volume sensor 1 is arranged in each wind measuring port 207. At this time, the scraping tool can be a scraper 24 fixedly connected to one end of the transmission shaft 23.

[0031] In use, first, the scraper 24 is extended to the carbon bowl together with the air blowing sleeve 20 until the small end of the tapered protrusion 204 extends into the carbon bowl, but the scraper 24 is stationary at this time and does not rotate. Then, air is supplied to the air blowing sleeve 20 through the air source interface 206 to uniformly blow air into the carbon bowl. The overflowed air from the carbon bowl is captured and measured by the air volume sensor 1, and the position of the scraping tool is adjusted while moving the air blowing sleeve 20 together. When all the air volume values are consistent, it indicates that the scraping tool is coaxial with the axis of the carbon bowl, and the alignment is completed. Then, the scraping tool is started, and the transmission shaft 23 drives the scraper 24 to rotate to clean the coke particles in the carbon bowl. At the same time, the axial position of the scraping tool can still be monitored when it rotates. When the rotation is eccentric, the air volume along the circumferential direction of the carbon bowl will be deviated and uneven, and the rotation of the scraping tool can be stopped in time to avoid damage to the carbon bowl due to the eccentricity of the scraper 24.

[0032] At this time, it should be noted that, in order to improve the reliability of detection, the air blowing sleeve 20 can be reciprocated along the axial direction of the transmission shaft 23 before the scraping tool is started, so as to repeatedly measure the air volume values at different positions along the axial direction of the transmission shaft 23. The air volume values at any axial position should be the same, thereby ensuring that the scraping tool is coaxial with the axis of the carbon bowl.

[0033] The advantages of the embodiment are:

[0034] (1) The position of the scraping tool is detected by air flow, which is non-contact and has no wear, and the accuracy of repeated measurement can be ensured.

[0035] (2) The blown air flow can not only be used for detection, but also can play a role in assisting the removal of coke particles or coke powder in the carbon bowl.

[0036] (3) The detection process and the adjustment process of the scraping tool can be controlled by program, achieving automatic detection and automatic adjustment without human intervention, which is fast and convenient.

[0037] (4) It has the ability of online detection, which can detect while the scraping tool is working, avoiding damage to the carbon bowl due to the eccentricity of the scraper 24.

[0038] Embodiment 2, please refer to Figure 2 ;

[0039] The alignment method of the embodiment is the same as that of embodiment 1, and the difference is that the gas discharged by the pneumatic tool bit 21 is used as the air source for detection. Specifically, the scraping tool comprises a pneumatic tool bit 21, so that when the pneumatic tool bit 21 discharges, air is uniformly blown into the carbon bowl; a plurality of air volume sensors 1 are circumferentially and uniformly arranged in the air volume detection ring 10; and the air volume detection ring 10 is coaxially sleeved outside the scraping tool.

[0040] Thus, the scraping tool comprises a pneumatic cutter head 21 and a rotating shaft 22; the pneumatic cutter head 21 is rotatably sleeved at one end of the rotating shaft 22, the end face is provided with a steel brush 211, and the side wall is provided with a plurality of exhaust holes 212 uniformly distributed in the circumference; the rotating shaft 22 is a hollow pipe for conveying high-pressure air to drive the pneumatic cutter head 21 to rotate; a plurality of air volume sensors 1 are uniformly distributed in an air volume detection ring 10; the air volume detection ring 10 is coaxially sleeved outside the scraping tool, and the center is provided with a cutter hole 101; the diameter of the cutter hole 101 is greater than the diameter of the carbon bowl.

[0041] The steel brush 211 comprises a plurality of steel wires bundled and fixed on the pneumatic cutter head 21, and is softer and deformable than the scraper of Embodiment 1, so that in the initial state, the pneumatic cutter head 21 is allowed to have a larger deviation when extending into the carbon bowl.

[0042] In use, the air volume detection ring 10 can be movable or fixed. When the air volume detection ring 10 is fixed, the carbon bowl of the carbon block is initially aligned after moving to the position of the air volume detection ring 10, the diameter of the cutter hole 101 is greater than the diameter of the carbon bowl, the pneumatic cutter head 21 of the scraping tool is extended into the carbon bowl, even if there is a certain deviation at this time, but the steel brush 211 is deformable and does not affect the rotation of the pneumatic cutter head 21. Then, air is supplied into the rotating shaft 22 to drive the pneumatic cutter head 21 to rotate, at this time the air volume detection ring 10 starts to detect, when all the air volume values are consistent, it indicates that the scraping tool is coaxial with the carbon bowl axis, and the alignment is completed. The pneumatic cutter head 21 of the scraping tool rotates in the carbon bowl while performing axial reciprocating motion, which plays a role in cleaning the carbon bowl.

[0043] The advantages of the embodiment are that:

[0044] The alignment method of the embodiment is the same as the principle of Embodiment 1, so on the basis of the advantages of Embodiment 1, the position detection of the pneumatic cutter head 21 is performed by using the natural exhaust of the pneumatic cutter head 21, which has the advantages of convenience, rapidness, simple structure, easy arrangement and lower cost.
