Description

Technical Field

[0001] This invention relates to a phosphorus pig iron cleaning system for anode steel claws, and more particularly to a cleaning system for removing excess phosphorus pig iron during the casting process, belonging to the electrolytic aluminum industry. Background Technology

[0002] The anode steel claw is a core component in the electrolytic aluminum process. It is assembled into a guide rod group by combining an explosive weld block and an aluminum guide rod. After the claw head is inserted into the anode carbon block, cast iron phosphorus is poured to form a conductive structure. However, the casting of the cast iron phosphorus is not always perfect, and some may overflow from the claw head. This overflowing pig iron needs to be cleaned up, which is a very laborious process. Summary of the Invention

[0003] The purpose of this invention is to provide a phosphorus pig iron cleaning system for anode steel claws, used to clean the phosphorus pig iron that overflows from the anode steel claws during the casting of phosphorus pig iron.

[0004] To solve the above problems, the phosphorus pig iron cleaning system for anode steel claws involved in this invention adopts the following technical solution: A phosphorus pig iron cleaning system for anode steel claws includes a vertical striking device and a horizontal striking device. The vertical striking device includes a first frame, with a first channel in the middle for the anode steel claw to be hoisted and moved through. Horizontal striking devices are arranged in pairs on both sides of the first channel. Each horizontal striking device includes a pre-crushing striking roller mounted horizontally on the first frame. The pre-crushing striking rollers of the pair of horizontal striking devices are symmetrically arranged on both sides of the first channel, and the pre-crushing striking rollers extend horizontally along the direction of the first channel. The horizontal striking device includes a second frame. The middle section has a second channel for the anode steel claw to move and move through. On both sides of the second channel, there are pairs of inclined swinging devices. The inclined swinging devices include cleaning swinging rollers that are tilted and rotated and mounted on the second frame. The cleaning swinging rollers of the pair of inclined swinging devices are symmetrically arranged on both sides of the second channel. The extension lines of the two cleaning swinging rollers of the pair of inclined swinging devices intersect above the second channel. The circumference of the pre-crushing swinging roller and the cleaning swinging roller are evenly arranged in rows of swinging chain devices. The chain in a row of swinging chain devices extends from one end of the corresponding pre-crushing swinging roller or cleaning swinging roller to the other end. Both the pre-crushing swinging roller and the cleaning swinging roller are driven to rotate by power.

[0005] The tilting and slapping device is installed on the cleaning box, which includes a square box body. The opening of the square box body faces the second channel and is detachably and fixedly mounted on the second frame. The cleaning and slapping roller is rotatably mounted at the opening of the cleaning box and enters the second channel.

[0006] The upper part of the square box has a mounting beam extending into the second channel, and the upper end of the cleaning and swishing roller is rotatably mounted on the mounting beam.

[0007] The angle between the axis of the cleaning and swishing roller and the horizontal plane is 45 degrees.

[0008] The first frame forms a first cavity with the first channel on both sides of the first channel outside the vertical striking device. The upper part of the first frame is provided with a suction port for connecting the dust collector. The second frame forms a second cavity with the second channel on both sides of the second channel outside the horizontal striking device. The upper part of the second frame is also provided with a suction port for connecting the dust collector.

[0009] The first frame and the second frame are connected as a whole. An inlet door is provided on the first frame at the inlet end of the first channel, and an outlet door is provided on the second frame at the outlet end of the second channel. Both the inlet door and the outlet door are flip-open double doors.

[0010] The pre-crushing and slapping roller is driven by a belt pulley device, while the cleaning and slapping roller is driven directly by a motor through a coupling.

[0011] The two doors of the exit door are rotatably assembled on the second frame via door hinges whose upper extension lines intersect. Torsion springs that drive the two doors to close are respectively fitted on the two door hinges.

[0012] The lower edge of the chain in the chain-spinning device of the cleaning and spinning roller is an oblique line corresponding to the inclined surface of the anode steel claw.

[0013] The second frame is provided with a cleaning station at the rear, and a cleaning suction port is provided above the cleaning station on the second frame.

[0014] This invention features a vertical striking device. The pre-crushing striking roller of the vertical striking device extends horizontally along the first channel. During rotation, its chain-swing device vertically strikes the anode steel claws stopped in the first channel, knocking off excess pig iron or causing fatigue fracture. The extension lines of the two cleaning striking rollers of the horizontal striking device intersect above the second channel. As the cleaning striking rollers rotate, their chain-swing devices horizontally strike the anode steel claws passing through the second channel, sweeping away the knocked-off or fatigue-fractured pig iron, thus achieving the cleaning of excess pig iron.

[0015] The tilting and slapping device of the present invention is mounted on a cleaning box, which includes a square box body. The opening of the square box body faces the second channel and is detachably and fixedly mounted on the second frame. The cleaning and slapping roller is rotatably mounted at the opening of the cleaning box and enters the second channel, and can be replaced individually. This extends the product's service life and reduces production costs.

[0016] The first frame of this invention forms a first cavity with the first channel on both sides outside the vertical striking device. A suction port for connecting a dust collector is provided at the top of the first frame. A second frame forms a second cavity with the second channel on both sides outside the horizontal striking device. A suction port for connecting a dust collector is also provided at the top of the second frame. This allows for the collection and cleaning of generated debris, thus purifying the production environment.

[0017] In this invention, the first frame and the second frame are integrated into a single unit. An inlet door is provided on the first frame at the inlet end of the first channel, and an outlet door is provided on the second frame at the outlet end of the second channel. The presence of the inlet door and the outlet further improves the sealing performance, thereby increasing the dust removal effect and further purifying the production environment.

Detailed Implementation

[0019] To make the technical objectives, technical solutions, and beneficial effects of the present invention clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention; that is, the described embodiments are merely some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] A specific embodiment of the phosphorus pig iron cleaning system for anode steel claws involved in this invention is as follows: Figures 1-17The device comprises a vertical striking device 1 and a horizontal striking device 2. The vertical striking device 1 has a first frame 3, and the horizontal striking device has a second frame 4. A channel, namely a first channel 5, is located in the middle of the first frame 3. The first channel 5 is used for the movement of the anode steel claw during lifting. The lifting and movement of the anode steel claw is existing technology and is very common. Generally, a moving device clamps the upper end of the anode steel claw's rod from above. This will not be described in detail here. On both sides of the first channel 5, a pair of horizontal striking devices 6 are arranged. Each horizontal striking device 6 has a horizontally rotating pre-crushing striking roller 7. The pre-crushing striking roller 7 is rotatably mounted on the first frame 3 via a bearing seat. The pre-crushing striking rollers 7 of the pair of horizontal striking devices 6 are symmetrically arranged on both sides of the first channel 5. The pre-crushing striking rollers 7 extend horizontally along the direction of the first channel 5. A pulley is provided at the end of the rotating shaft of the pre-crushing striking roller 7, which is connected to a motor via a belt drive and driven by the motor to rotate. Three rows of chain-spinning devices are arranged evenly on the circumference of the pre-crushing and spinning drum 7. The chain 8 in one row of chain-spinning devices extends from one end of the corresponding pre-crushing and spinning drum 7 to the other end. The chain 8 is made up of elongated oval chain links connected in sequence. The assembly method on the circumference of the pre-crushing and spinning drum 7 is as follows: partition ears 9 are arranged axially on the circumference of the pre-crushing and spinning drum 7. The mounting shaft 10 passes through each partition ear 9 in sequence. The connecting link at the end of the chain 8 extends between two adjacent partition ears 9 and is sleeved on the mounting shaft 10.

[0021] The transverse striking device 2 has a second frame 4, with a channel 11 in the middle of the second frame 4 for the anode steel claw to move through during hoisting. On both sides of the second channel 11, there are pairs of inclined striking devices 12, each with a tilted, rotatably mounted cleaning striking roller 13. The cleaning striking roller 13 is rotatably mounted on the second frame 4 via a bearing seat, and its axis is tilted at a 45-degree angle to the horizontal plane. The cleaning striking rollers 13 of the pair of inclined striking devices 12 are symmetrically arranged on both sides of the second channel 11. The extension lines of the two cleaning striking rollers 13 of the pair of inclined striking devices 12 intersect above the second channel 11. The ends of the rotating shafts of the cleaning striking rollers 13 are connected to a motor via a coupling and are driven to rotate by the motor. Three rows of chain-spinning devices are arranged evenly on the circumference of the cleaning roller 13. The chain-spinning devices here have the same structure as the chain-spinning devices of the pre-crushing roller 7, and their connection method is also the same as the assembly method of the pre-crushing roller 7 and the chain-spinning devices on it.

[0022] Furthermore, the tilting and slapping device 12 is installed on the cleaning box, which has a square box body 14. The opening of the square box body 14 faces the second channel 11 and is detachably and fixedly mounted on the second frame 4. The cleaning and slapping roller 13 is rotatably mounted at the opening of the square box body 4 and enters the second channel 11.

[0023] Furthermore, the upper part of the square box 4 has a mounting beam 15 extending towards the second channel 11, and the upper end of the cleaning and swishing roller 13 is rotatably mounted on the mounting beam 15.

[0024] Furthermore, the outer side of the vertical striking device forms a first cavity with the first channel, and the upper part of the first frame 3 is provided with a suction port 16 for connecting the dust collector. The second frame 4 forms a second cavity with the outer side of the horizontal striking device on both sides of the second channel, and the upper part of the second frame 4 is also provided with a suction port for connecting the dust collector.

[0025] Furthermore, the first frame 3 and the second frame 4 are connected as a whole. The first frame is at the front of the process and the second frame is at the rear of the process. The first frame 3 has only one station on both sides of the first channel 5 for the vertical striking device. When striking, the anode steel claw is stationary. After striking, it moves to the second channel.

[0026] Furthermore, in the chain-spinning device of the cleaning roller, the lower edge of the chain forms an oblique line corresponding to the bevel of the anode steel claw. That is, the higher chain lengths are longer, and the lower chain lengths are shorter, forming a structure similar to a straight line, such as... Figure 6 As shown.

[0027] Furthermore, a horizontally positioned guide rod 19 is provided on the upper part of the first channel and the second channel of the first frame and the second frame. The guide rod 19 extends out of the first channel, and the extended part separates outward to form a flared guide for the anode steel claw.

[0028] The rear of the second frame has a simple cleaning station without a horizontal hammering device; it only has a suction port for cleaning at the top. It is used for powerful cleaning of pig iron shavings.

[0029] Furthermore, an inlet door is provided on the first frame 3 at the inlet end of the first channel, and an outlet door is provided on the second frame at the outlet end of the second channel.

[0030] Furthermore, both the inlet door 20 and the outlet door 21 are double-leaf doors with a hinged opening.

[0031] Furthermore, the two doors of the exit door are rotatably mounted on the second frame via door hinges whose upper extension lines intersect. Because the door hinges are inclined, the two doors tend to close under the influence of gravity. To ensure that both doors can close, torsion springs are installed on each door hinge. The torsion springs drive the doors to close; since it is a double door, the two torsion springs rotate in opposite directions. The working principle of the torsion springs is existing technology and will not be described in detail again.

[0032] Furthermore, the two doors of the inlet door are rotated and mounted on the second frame, and are driven to open by the upper crank-slider mechanism 17, while the sliding block is a pneumatic cylinder 18.

[0033] In the above embodiment, the angle between the axis of the cleaning and swishing roller and the horizontal plane is 45 degrees. In other embodiments, other tilt angles are also possible.

[0034] In the above embodiment, the first frame and the second frame are connected as a whole. The first frame is provided with an inlet door at the inlet end of the first channel, and the second frame is provided with an outlet door at the outlet end of the second channel. In other embodiments, the first frame and the second frame can be separated, with two inlet doors and two outlet doors.

[0035] In the above embodiments, both the entrance and exit doors are hinged double doors. In other embodiments, sliding doors may also be used.

[0036] In the above embodiment, the pre-crushing and churning roller is driven by a pulley device, while the cleaning and churning roller is driven directly by a motor through a coupling. This is one specific driving method; other driving methods can also be used in other embodiments.

[0037] Finally, it should be noted that the above embodiments are only for illustration and not for limiting the technical solutions of the present invention. Any equivalent substitutions, modifications or partial substitutions that do not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
