Problems solved by technology

The mechanism of this method is that when the carbon block has internal cracks, its natural frequency changes, and at the same time, the cracks cause the free vibration damping to increase after hammering. Therefore, the sound of the cracked carbon block is different from that of the normal carbon block. This method needs to be equipped with a large number of inspectors and takes up a lot of manpower.

Abstract

The invention discloses an internal crack detection system for a prebaked anode carbon block. The internal crack detection system comprises a support frame, a conveying mechanism and a knocking mechanism, a jacking mechanism is arranged below the supporting frame and can support the carbon blocks and drive the carbon blocks to be away from the conveying mechanism. A plurality of groups of knocking mechanisms are arranged, and the plurality of groups of knocking mechanisms respectively knock different surfaces of the carbon block; the detection system further comprises a computer; the knocking mechanism is provided with a probe abutting against the carbon block, and the probe receives vibration generated by the carbon block when the knocking mechanism knocks the carbon block, converts the vibration into sound and transmits the sound to the computer. According to the detection system, the conveying mechanism is used for conveying the carbon block, the knocking mechanisms are arranged on the three faces of the carbon block respectively, the knocking mechanisms can rapidly knock the surface of the carbon block, meanwhile, the knocking mechanisms receive vibration of the carbon block through probes so as to drive internal vibration pieces to vibrate air, and the air is transmitted to a computer through a microphone; compared with manual detection, the mode for detecting the internal crack condition of the carbon block has the advantages that the detection effect is more accurate, and the operation efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of prebaked anode carbon block detection, in particular to a prebaked anode carbon block internal crack detection system and a detection method based on the detection system. Background technique [0002] The prebaked anode is made of calcined petroleum coke as the aggregate and coal tar pitch as the binder, and is used as the anode material for the aluminum electrolytic cell. In the production process, the product is first vibrated to form a green body, and then calcined to become a finished carbon block. When the finished carbon block with internal cracks is put into the electrolytic aluminum cell, it is prone to falling blocks or even "dropping", which seriously affects the normal operation of the aluminum electrolytic cell, affects the quality of the product, and may cause damage to the equipment. Due to the complexity of the roasting electrode production process and raw materials, it is currently impos...
