[0002] In the industrial production of electrolytic aluminum, anode carbon blocks are usually used as anodes for aluminum electrolysis cells. With the increasingly strict requirements for energy conservation and emission reduction, various new anodes have been continuously developed. Among them, anode carbon blocks with grooved soles have certain practical significance in aspects such as reducing the working voltage, reducing the anode efficiency coefficient, maintaining the stability of the electrolysis cell, improving the current efficiency, and strengthening the current.

[0003] After retrieval, a patent application with the patent application number 202211422247.3 discloses a grooving device for anode carbon blocks. It includes an anode carbon block roller conveyor line, an anode carbon block roller conveyor line, and also includes an anode carbon block conveying A stroke limit switch device, an anode carbon block pusher device, an anode carbon block receiving, supporting, lifting and conveying device, an anode carbon block grooving device, an anode carbon block grooving dust collection device, and an anode carbon block spraying device. The installation structure of the left and right two circular saw blades fixed relatively by keys and fixing nuts on the parts of the output shafts of the left and right two gearboxes extending into the space between the left and right two narrow strip-shaped brackets with top plates is also convenient for adjusting the distance between the left and right two circular saw blades, and thus convenient for adapting to the grooving of anode carbon blocks with different required grooving distances.

[0004] Although the above patent can achieve the function of grooving anode carbon blocks, the current technology has incomplete considerations and has the following disadvantages: 1. The adjustment of the center distance of the grooving saw blades at the bottom of the carbon anode needs to be manually adjusted. 2. The powder particles generated during the grooving of the anode carbon block leak into the on-site environment along with the air flow, polluting the on-site environment and posing a health hazard to on-site operators.

[0005] To solve one of the above problems, there is an urgent need for a grooving and cutting device for the bottom of a carbon anode. Content of the Utility Model

[0006] According to the deficiencies in the above prior art, the technical problem to be solved by the utility model is: how to drive the left mobile mounting base and the right mobile mounting base to approach or move away from each other through the grooving center distance adjustment mechanism, and then adjust the distance between the left grooving saw blade and the right grooving saw blade to realize the adjustment of the grooving center distance at the bottom of the carbon anode. For this purpose, a grooving and cutting device for the bottom of a carbon anode is provided.

[0007] The grooving and cutting device at the bottom of the carbon anode of the present utility model includes a left shaft sleeve and a left rotating shaft arranged coaxially, and a right shaft sleeve and a right rotating shaft arranged coaxially. It is characterized in that it further includes a left movable mounting base and a right movable mounting base arranged at intervals, and a grooving center distance adjusting mechanism for driving the left movable mounting base and the right movable mounting base to approach or move away from each other. The left shaft sleeve is fixed on the upper surface of the left movable mounting base. The middle part of the left rotating shaft is rotatably installed in the left shaft sleeve through bearing A. One end of the left rotating shaft is detachably installed with a left grooving saw blade, and the other end of the left rotating shaft is power-connected to a left grooving reduction motor. The right shaft sleeve is fixed on the upper surface of the left movable mounting base. The middle part of the right rotating shaft is rotatably installed in the right shaft sleeve through bearing B. One end of the right rotating shaft is detachably installed with a right grooving saw blade, and the other end of the right rotating shaft is power-connected to a right grooving reduction motor.

[0008] The left grooving reduction motor is used to drive the left grooving saw blade to rotate, and at the same time, the right grooving reduction motor is used to drive the right grooving saw blade to rotate. When the anode carbon block passes through the saw blade, grooving and cutting at the bottom of the anode carbon block can be realized. When switching the variety of the anode carbon block, according to the center distance dimension corresponding to the preset variety of the system, the left movable mounting base and the right movable mounting base are driven to approach or move away from each other through the grooving center distance adjusting mechanism, so as to adjust the distance between the left grooving saw blade and the right grooving saw blade, and realize the adjustment of the grooving center distance at the bottom of the carbon anode.

The first lead screw nut and the second lead screw nut threadedly connected to the first thread segment and the second thread segment are respectively installed on the left movable mounting base and the right movable mounting base, and a distance adjusting drive motor is respectively connected to both ends of the bidirectional ball screw.

[0010] When the distance adjusting drive motor drives the bidirectional ball screw to rotate forward or backward, the bidirectional ball screw cooperates with the first lead screw nut and the second lead screw nut to drive the left movable mounting base and the right movable mounting base to move towards each other or in the opposite direction along the length direction of the main machine base guide rail. The left grooving saw blade and the right grooving saw blade move respectively with the left movable mounting base and the right movable mounting base, so as to adjust the distance between the left grooving saw blade and the right grooving saw blade, and realize the adjustment of the grooving center distance at the bottom of the carbon anode.

[0011] Preferably, the left grooving reduction motor and the right grooving reduction motor are respectively fixed on the left mobile mounting base and the right mobile mounting base.

The opening of the saw blade dust collection groove faces upward, and the bottom of the saw blade dust collection groove has a dust collection outlet. The dust collection outlet is connected to a dust collection device through a dust collection pipeline.

At the same time, the right-side grooving reduction motor 9 is used to drive the right-side grooving saw blade 8 to rotate. When the anode carbon block passes through the saw blade, the bottom grooving cutting of the anode carbon block can be realized. When switching the variety of the anode carbon block, according to the preset center distance dimension of the corresponding variety in the system, the left mobile mounting base 5 and the right mobile mounting base 10 are driven to approach or move away from each other by the grooving center distance adjustment mechanism, so as to adjust the distance between the left-side grooving saw blade 3 and the right-side grooving saw blade 8, and realize the adjustment of the bottom grooving center distance of the carbon anode.
