AI Technical Summary
The existing methods of charcoal crack detection rely on naked eye observation, making it difficult to detect fine cracks, and the charcoal block needs to be flipped to detect the bottom, resulting in incomplete detection and possible damage to the charcoal block.
A carbon block crack quality detector was designed, using a lifting motor and threaded column to drive the fixing frame up and down, and combining a dual-axis motor and threaded block to adjust the positions of the enlargement plate and the imaging plate to achieve one-time enlargement imaging of all surfaces of the carbon block to avoid flip detection.
The detection of all surfaces of the carbon block surface is achieved with high magnification, which significantly improves the detection accuracy and efficiency of cracks and avoids mass damage when the carbon block is flipped.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carbon block crack quality detection, in particular to a carbon block crack quality detector. Background Art
[0002] Carbon block refers to the carbon block produced with petroleum coke and asphalt coke as aggregate and coal tar as binder, which is used as anode material for pre-baked aluminum electrolytic cell. This carbon block has been baked and has a stable geometric shape, so it is also called pre-baked anode carbon block, and is also customarily called carbon anode for aluminum electrolysis.
[0003] Anode carbon blocks are an important component of aluminum electrolytic cells, which are beneficial to energy saving in aluminum electrolytic production and improving the life of the cell. During the production process of carbon blocks, it is necessary to inspect the surface of the formed carbon blocks to check whether there are cracks on the surface of the carbon blocks.
[0004] The existing detection method is to observe with the naked eye of the operator. Since the surface of the carbon block is black, some fine cracks cannot be observed, which will cause the carbon block to crack later. Since the carbon block is large in size, the bottom of the carbon block cannot be observed with the naked eye. The carbon block needs to be turned over for observation, which will also cause damage to the carbon block. To this end, we provide a carbon block crack quality detector to solve the above problems.

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] like Figure 1-6 As shown, the utility model provides a technical solution: a carbon block crack quality detector, including a base 1, a lifting motor 8 is fixed on the top of the base 1, and a threaded column 9 is fixed on the output shaft of the lifting motor 8, and the threaded column 9 is threadedly connected to the fixing frame 2 through the thread on the surface of the threaded column 9, so that the threaded column 9 can rotate to drive the fixing frame 2 to move up and down, a transparent plate 3 is arranged on the top of the base 1, and fixing plates 5 are arranged on the surface of the base 1 and the front, back, left, and right opposite surfaces of the fixing frame 2 and the bottom of the top, and the fixing plate 5 on the surface of the base 1 is located directly below the transparent plate 3, a groove 12 is opened in the fixing plate 5, a double-axis motor 13 is arranged in the groove 12, the output shaft of the double-axis motor 13 is fixedly connected to a threaded rod 14, a threaded block 17 is threadedly connected to the surface of the threaded rod 14, and a connecting block 16 is fixed on the surface of the threaded block 17, the connecting block 16 is movably connected to a connecting rod 15 through a pin 18, and the other end of the connecting rod 15 is fixed with an imaging plate 6 through the pin 18 and the connecting block 16, and an enlargement plate 7 is fixed on the surface of the imaging plate 6.
[0027] In the above scheme, the lifting motor 8 and the threaded column 9 are arranged to drive the fixed frame 2 to move up and down, and at the same time, it will not hinder the transmission of the carbon block, and it is also convenient for the detection of the carbon block. In particular, the magnifying plate 7 and the imaging plate 6 are arranged in the front, back, left, right, top and bottom of the transparent plate 3, which can magnify and image all sides of the carbon block at one time, making it convenient to observe whether there are cracks on the surface of the carbon block. At the same time, it can also avoid flipping of the carbon block and reduce the quality problems caused by flipping the carbon block.
[0028] Specifically, Figure 5 and 6As shown, two threaded rods 14 are arranged in the groove 12, and the surface threads of the threaded rods 14 are threads in the same direction, and the internal threads of the threaded blocks 17 matched with the threaded rods 14 are threads in opposite directions. A bearing 19 is arranged on the inner wall of the groove 12, and a rotating shaft 20 is arranged in the bearing 19, and the rotating shaft 20 is fixed to the threaded rods 14. By setting the threaded blocks 17 with threads in opposite directions, the magnifying plate 7 and the imaging plate 6 can be driven to move through the connecting rod 15, the connecting block 16 and the pin 18 when the dual-axis motor 13 moves, thereby adjusting the distance between the magnifying plate 7 and the imaging plate 6 and the carbon block above the transparent plate 3, realizing magnification of different multiples, and being able to more clearly observe whether there are cracks on the surface of the carbon block.
[0029] Specifically, Figure 3 and 4 As shown, a limiting groove 10 is provided above the base 1, a limiting block 11 is arranged in the limiting groove 10, and the surface of the limiting block 11 is fixed to the bottom end of the transparent plate 3, a placement groove is provided on the surface of the transparent plate 3, and a rotating pulley 4 is arranged inside the placement groove. By adopting the limiting groove 10 and the limiting block 11, it is convenient for the operator to remove the transparent plate 3 from the base 1, and clean the carbon ash remaining on the surface of the transparent plate 3 in time, so as to reduce the influence on the crack detection at the bottom end of the carbon block.
[0030] Working principle: Before the carbon block is inspected, the formed carbon block is conveyed to the transparent plate 3 through an external conveying device and moved through the pulley 4 on the surface of the transparent plate 3. During the inspection, the lifting motor 8 is started by the external controller. The rotation of the lifting motor 8 drives the threaded column 9 to rotate and moves the fixed frame 2 downward through the threaded connection between the threaded column 9 and the fixed frame 2, and at the same time, the front, back, left, right, and upper magnifying plate 7 and imaging plate 6 of the fixed frame 2 are moved downward. After moving to the specified position, the dual-axis motor 13 is started, and the threaded rods 14 at both ends of the dual-axis motor 13 drive the surface threaded block 17 to move. While the threaded block 17 moves, it can drive the imaging plate 6 and the surface magnifying plate 7 to move through the connecting block 16, the pin 18 and the connecting rod 15, and realize the magnification through the distance between the magnifying plate 7 and the carbon block, and transmit the magnified picture to the external display through the imaging plate 6 to observe whether there are cracks on the surface of the carbon block. After the inspection is completed, the lifting motor 8 drives the fixed frame 2 to rise, and finally the carbon block above the transparent plate 3 is removed by the conveying device.
