The number of the connecting rods 26 and the number of the angle steels 61 are respectively 2, the screw rod 64 sequentially penetrates through the snap rings 63 and the 2 connecting rods 26, the bosses 67 are embedded between the two snap rings 63, and the first external threads 65 and the second external threads 66 are respectively positioned in the internal threads of the 1 connecting rods 26. The top ends of the 2 connecting rods 26 are fixedly connected with the 1 positioner 61 respectively. The 2 angle steels 61 are respectively positioned at two sides of the platform 14, and the horizontal section is in a shape of a cross with opposite openings. Rubber 65 is provided inside the angle steel 61. The vertical point of the center of the 2-angle steel 61 is positioned on the central line of the platform 14. The drilling device 50 includes a drill bit 8, a drilling motor 47, a lift motor 48, and a connecting rod 56. The upper end of the connecting rod 56 is driven by the drilling motor 47, and the lower end is connected with the drill bit 8. The drilling motor 47 is located at the top of the drilling device 50 and drives the drill bit 8 in rotation. The lifting motor 48 is positioned on the side surface of the drilling device 50 and drives the drilling motor 47, the drill bit 8 and the like to lift. The centre line of the drill bit 8 is parallel to the plumb line. The platform 14 is arranged horizontally and bears the graphite block to be processed. The dust suction device 9 includes a dust suction hood 33, a dust suction hood support 34, and a delivery pipe 35. The dust hood 33 is mounted on a dust hood support 34 and connected to a dust removal system (not shown) via a delivery pipe 35.

When the graphite anode drilling machine works, the belt conveying device 4 conveys the graphite block 5 with the thickness of about 100mm and the circular-arc or rectangular cross section to a drilling position on the platform 14 according to the width direction of the graphite block 5 which is basically vertical to the advancing direction of the graphite block 5. The lead screw 64 of the positioning mechanism is driven by the positioning motor to rotate, so that the two angle steels 61 are driven to fold from two sides to the middle, after 1 angle steel 61 contacts the outer side vertical plane or the outer arc surface of the graphite block 5, the two angle steels gradually move towards the middle along with 2 angle steels 61, the graphite block 5 is pushed to move towards the other 1 positioner 61 until the other positioner 61 contacts the outer side vertical plane or the outer arc surface of the other side of the graphite block 5, the rubber 65 on the inner side of the 2 angle steels 61 respectively supports against the corners on the outer sides of the 1 graphite block 5, the two positioners 61 simultaneously apply centripetal force to the graphite block 5 under the action of the lead screw 64, and the graphite block 5 is fixed on the platform 14. The center line of the drill bit 8 (about 8.5mm in diameter) of the drilling device 50 is then positioned about 15mm from the edge of the graphite block 5, and the drill bit 8 is driven by the drilling motor to rotate and simultaneously move downward by the lifting motor to drill a plurality of first holes 62 in the top surface of the graphite block 5. The first hole 62 has a depth of 50-100 mm. When the drill bit 8 drills on the top surface of the graphite block 5, the dust suction cover 33 of the dust suction device 9 covers the top surface of the graphite block 5 near the drill bit 8, a fan (not shown in the figure) sucks air, and graphite chips drilled by the drill bit 8 are sucked in through the dust suction cover 33 by utilizing the air carrying, and enter a dust removal system (not shown in the figure) through the delivery pipe 35 to recover the graphite chips. The recovered graphite scraps can be used for manufacturing electrolytic furnaces and the like.

The screw rod 64 is driven by the positioning motor to rotate reversely to drive the two angle steels 61 to loosen towards two sides, and the binding of the anode blank 85 is removed. The anode blank 85 leaves the drilling position on the platform 14 under the pushing of the subsequent graphite block 5 pushed by the belt conveyor 4 to enter a tapping process to machine the first hole 62 into the internal threaded hole 82 or directly drive a self-tapping screw into the anode blank 85 by a tapping machine, and fix the anode conductive plate on the surface of the anode blank 85.

The plurality of first holes 62 on the anode blank 85 are arranged in 2 rows, and the adjacent first holes 62 are arranged in a triangle. After the anode conducting plate is fixed on the top of the graphite anode 95 by the bolts, the stress condition of the screw hole internal threads of the graphite anode with only a single row of screw holes in the transportation, installation and use processes is changed, and the defects that the first screw hole 82 and the edge of the first screw hole 82 and the graphite anode 95 are easily damaged can be reduced.

The drilling motor 47 and the lifting motor 48 can also be combined into 1 motor to complete the work tasks of rotating and lifting the drill bit 8.

The lead screw 64 may also be disposed above and/or laterally to the platform 14.

When the drill 8 is horizontally disposed, the graphite block 5 can be horizontally disposed in the height direction, and the graphite dust can be easily discharged when the drill 8 drills the first holes 62.

The graphite block 5 is stationary relative to the ground while the graphite anode drill drills a plurality of first holes 62 in the upper surface of the graphite block 5.

Continuing to increase the number of first holes 62 and/or second holes 64, 60 may also reduce the depth of first holes 62 and second holes 64, 60 to 20-30 mm.

When the graphite anode drilling machine works, the first hole 62 is drilled, the graphite block 5 is rotated by 180 degrees along the plumb line, and the second hole 64 is drilled. After machining, the first hole 62 and the second hole 64 form a 4 ° included angle with each other.

The inclination angle α of the platform 14 may be set within a range of 1 to 45 ° to obtain different second included angles β.

The first hole 62 and the third hole 60 are in a straight line with different planes.

The depth of the third hole 60 can be reduced to less than or equal to 30mm, and the bolt arranged in the screw hole formed by the third hole 60 during electrolysis of the graphite anode 95 can be prevented from contacting molten salt and the like.

The first screw hole 82 and the second screw hole 84 which are made after the tapping of the first hole 62 and the second hole 64 and the third screw hole 80 which is made after the tapping of the third hole 60 share the weight of the graphite anode, so that the extension line of the gravity center of the graphite anode passes through a triangle formed by the first screw hole 82, the second screw hole 84 and the third screw hole 80, the condition that the graphite anode is only born by the first screw hole 82 and the second screw hole 84 originally is changed, and the first screw hole 82 and the second screw hole 84 are easy to damage due to gravity when the positions of the first screw hole 82 and the second screw hole 84 are positioned at the edge, and the effect of protecting the thinnest link of the graphite anode is achieved. After the depths of the first hole 62, the second hole 64 and the third hole 60 are reduced, the utilization rate of the graphite anode can be further improved on the premise that the bolts do not contact materials in the electrolytic furnace such as molten salt during electrolysis.

When the graphite anode drilling machine 7 drills a plurality of first holes 62 and/or second holes 64 and third holes 60 on the upper surface of the graphite block 5, the graphite block 5 is static relative to the ground.

EXAMPLE III

A graphite anode drilling machine, see fig. 1, 5, 7, 8, 9, 10 and 11.

This embodiment is substantially the same as the second embodiment. The difference lies in that: the two delivery pipes 35 are respectively arranged at two sides of the drill bit 8. Most of the graphite dust can be recovered.

Example four

EXAMPLE five

A graphite anode drilling machine, see fig. 1, 5, 7, 8, 9, 10 and 11.

This embodiment is substantially the same as the first embodiment. The difference lies in that: the centre line of the drill bit 8 running up and down in the drilling device 50 is about 1 deg. off the vertical.

When the drilling machine works, a first hole 62 with the center line inclined to the left is firstly machined in the top of the graphite block 5, then the graphite block 5 is rotated by 180 degrees along the vertical line, and a second hole 64 is continuously machined in the top of the graphite block 5. Such that first hole 62 and second hole 64 have a second included angle beta of about 2 deg..

In the transportation, installation and use process of the graphite block 5 manufactured by the graphite anode drilling machine of the embodiment after the graphite anode 95 is manufactured, because the second included angle β is formed between the center lines of the 2 self-tapping screws 74 and/or the 2 bolts 75, the two self-tapping screws 74 and/or the two bolts 75 clamp and/or hook the graphite anode 95, and the gravity of the graphite anode 95 borne by the internal threads of the first screw hole 82 and the second screw hole 84 of the graphite anode 95 is greatly reduced. The chance that the first and second screw holes 82 and 84 of the graphite anode 95 are damaged by the gravity of the graphite anode 95 is reduced.

When the graphite anode 95 has at least 3 self-tapping screws 74 and/or two bolts 75 arranged in a triangular shape, and the second included angle β is 10-90 °, the damage of the first screw hole 82 and the second screw hole 84 of the graphite anode 95 by the gravity of the graphite anode 95 can be substantially avoided.

After the hole on the surface of the graphite block 5 is drilled, the first rack 72 or the second rack 73 moves linearly in the opposite direction under the dragging of the piston, so that the connecting rods 26 move back and forth to be separated.

When the graphite block 5 needs to be conveyed to the platform 14, the piston rod 31 extends towards the platform 14, and the graphite block 5 on the roller way is pushed towards the platform 14. The piston rod 31 repeatedly extends towards the platform 14 to push the graphite blocks 5 towards the platform 14 until one graphite block 5 reaches the drilling position of the platform 14, the piston rod 31 resets, and the drilling device 50 starts to drill. After the graphite blocks 5 on the platform 14 are drilled, the piston rods 31 extend towards the platform 14 again, the graphite blocks 5 drilled on the roller way are pushed to the drilling positions of the platform 14, and the anode blanks 85 drilled with the first holes 62 are pushed away from the drilling positions of the platform 14.
