Description

Technical Field

[0001] This invention relates to the field of graphite blank firing technology, and in particular to a graphite filler device. Background Technology

[0002] The process of firing graphite blanks requires first filling the graphite blank box with powder from the powder silo, and then moving the graphite blank box away by a gantry crane. Since the outlet of the powder silo is fixed, the next graphite blank box can only be filled after the previous one has been moved away. At the same time, the gantry crane needs a certain amount of time to clear the space for filling when hoisting the graphite blank box, which reduces the filling efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a graphite packing device that can feed powder into the corresponding graphite blank box according to the needs.

[0004] To address the aforementioned problems, the present invention provides a graphite packing device, comprising a powder silo for storing powder, a feeder for conveying powder from the powder silo, a feeding switching device for switching the powder feeding position, a hanger for mounting the feeding switching device, and a first feeding pipe, a second feeding pipe, and a third feeding pipe for feeding powder to corresponding graphite blank boxes. The powder silo has a discharge port, the feeder is installed at the discharge port of the powder silo, the hanger is installed on the powder silo, and the first, second, and third feeding pipes are installed on the feeding switching device. The feeding switching device includes a first discharge port, a second discharge port, and a third discharge port. The device comprises a material box for the material inlet, a first valve plate and a second valve plate for opening or closing a first discharge port, a second discharge port, or a third discharge port, a shaft for driving the first valve plate and the second valve plate to rotate synchronously, and a switching driver for driving the shaft to rotate. The first valve plate and the second valve plate are connected to the shaft via a connecting rod. The first feed pipe is installed at the first discharge port, the second feed pipe is installed at the second discharge port, and the third feed pipe is installed at the third discharge port. The feeder is connected to the material box, and the switching driver is installed on the material box. The distance between the first valve plate and the second valve plate is greater than the diameter of the second discharge port and less than the minimum distance between the first discharge port and the third discharge port.

[0005] Furthermore, the feeding switching device also includes a connecting pipe for connecting to the feeder, the connecting pipe being disposed on the material box.

[0006] Furthermore, it also includes a telescopic dust cover for dust prevention and a telescopic drive mechanism for pulling up or lowering the telescopic dust cover. The first feeding pipe, the second feeding pipe and the third feeding pipe are each provided with a telescopic dust cover and a telescopic drive mechanism. The telescopic dust cover is installed on the corresponding first feeding pipe, the second feeding pipe and the third feeding pipe, and the telescopic drive mechanism is installed on the hanger.

[0007] Furthermore, the telescopic drive mechanism includes a traction rope for pulling up or lowering the telescopic dust cover, a pulley for winding up or releasing the traction rope, and a telescopic driver for driving the pulley to rotate. The telescopic driver is mounted on the hanger and has two coaxial output ends. The two pulleys are mounted on the output ends and two reversing wheels. One end of the traction rope is fixed to the pulley, and the other end of the traction rope is connected to the lower end of the telescopic dust cover.

[0008] Furthermore, the telescopic drive mechanism also includes a reversing wheel for changing the direction of the traction rope, a rotating shaft for mounting the reversing wheel, and a mounting plate for mounting the rotating shaft. The mounting plate is mounted on the hanger. There are two reversing wheels. One end of the traction rope is fixed to the pulley, and the other end of the traction rope passes around the reversing wheel and is connected to the lower end of the telescopic dust cover.

[0009] Furthermore, the first feeding pipe includes a first guide pipe for guiding the powder to the top of the corresponding graphite blank box and a first mounting pipe for installing a telescopic dust cover. The upper end of the first guide pipe is connected to the material box of the feeding switching device, and the first guide pipe is connected to the middle of the first mounting pipe. The first mounting pipe is provided with two symmetrical through holes for two traction ropes to pass through.

[0010] Furthermore, the second feeding pipe includes a second guide pipe for guiding the powder to the top of the corresponding graphite blank box and a second mounting pipe for installing a telescopic dust cover. The upper end of the second guide pipe is connected to the material box of the feeding switching device, and the second guide pipe is connected to the middle of the second mounting pipe.

[0013] Furthermore, it also includes a negative pressure suction pipe for vacuuming, with the first, second, and third feeding pipes all connected to a negative pressure suction pipe.

Changing the feeding position is convenient and quick. During the switching process, only the first valve plate and the second valve plate need to rotate. The first valve plate and the second valve plate are located inside the material box and will not affect the outside. There is no need to switch by swinging, which improves safety.

[0023] The invention will now be further described with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2As shown, a preferred embodiment of the graphite filler device of the present invention includes a powder silo 11, a hanger 12, a feeder 2, a feeding switching device 3, a first feeding pipe 41, a second feeding pipe 42, a third feeding pipe 43, a telescopic dust cover 5, a telescopic drive mechanism 6, and a negative pressure dust suction pipe 7. The powder silo 11 is used to store the powder for firing graphite blanks. The lower end of the powder silo 11 has a discharge port for discharging the powder from the silo 11. The inlet of the feeder 2 is connected to the outlet of the powder silo 11, and the outlet of the feeder 2 is connected to the feeding switching device 3, thus enabling the feeder 2 to feed the powder from the powder silo 11 into the feeding switching device 3. The hanger 12 is mounted on the powder silo 11, and the feeding switching device 3 is fixed to the hanger 12. The first feeding pipe 41, the second feeding pipe 42, and the third feeding pipe 43 are all connected to the feeding switching device 3. The feeding switching device 3 is used to feed powder into the first feeding pipe 41, the second feeding pipe 42, or the third feeding pipe 43 as needed. The first feeding pipe 41, the second feeding pipe 42, and the third feeding pipe 43 are all used to feed materials into the corresponding graphite blank hopper 31. The first feeding pipe 41, the second feeding pipe 42, and the third feeding pipe 43 are all equipped with the telescopic dust cover 5. The telescopic dust cover 5 is used to gather the powder and discharge it into the graphite blank hopper 31. By using the telescopic dust cover 5, the position of the powder discharge can be lowered to inside the graphite blank hopper 31. That is, the telescopic dust cover 5 reduces the height difference of dust from the outlet to inside the graphite blank hopper 31, which can reduce the generation of dust. Each of the first feeding pipe 41, the second feeding pipe 42, and the third feeding pipe 43 is equipped with a telescopic drive mechanism 6, which is mounted on the hanger 12. The telescopic drive mechanism 6 is used to drive the telescopic dust cover 5 to extend and retract. Each of the first feeding pipe 41, the second feeding pipe 42, and the third feeding pipe 43 is equipped with a negative pressure suction pipe 7, which is used to suck up the dust floating inside the telescopic dust cover 5 after feeding is completed.

[0025] The feeding switching device 3 includes a material box 31, a switching driver 32, a shaft 33, a first valve plate 34, a second valve plate 35, and a connecting pipe 36. The connecting pipe 36 is located on the top of the material box 31 and is used to connect to the feeder 2. The connecting pipe 36 receives the powder fed by the feeder 2 and guides it into the material box 31. The material box 31 is provided with a first discharge port, a second discharge port, and a third discharge port. The powder in the material box 31 is discharged through the first discharge port, the second discharge port, and the third discharge port. The first discharge port, the second discharge port, and the third discharge port are evenly distributed on the material box 31. The first feeding pipe 41 is installed at the first discharge port, the second feeding pipe 42 is installed at the second discharge port, and the third feeding pipe 43 is installed at the third discharge port. The switching driver 32 is installed on the outer wall of the material box 31. The output end of the switching driver 32 is fixed to the shaft 33. The shaft 33 is rotatably disposed inside the material box 31. The switching driver 32 is used to drive the shaft 33 to rotate. The first valve plate 34 and the second valve plate 35 are both fixed to the shaft 33 through the connecting rod 37. The first valve plate 34 and the second valve plate 35 are both used to close the first discharge port, the second discharge port, or the third discharge port. The first valve plate 34 and the second valve plate 35 are spaced apart, and the distance between the first valve plate 34 and the second valve plate 35 is greater than the diameter of the second discharge port and less than the minimum distance between the first discharge port and the third discharge port. This ensures that the first valve plate 34 and the second valve plate 35 can only close two of the first discharge port, the second discharge port, or the third discharge port, ensuring that only the first discharge port, the second discharge port, or the third discharge port can be fed during feeding, thereby feeding the powder into the corresponding first feeding pipe 41, the second feeding pipe 42, or the third feeding pipe 43. Specifically, when the first valve plate 34 closes the first discharge port and the second valve plate 35 closes the third discharge port, the second discharge port is open; when the first valve plate 34 closes the first discharge port and the second discharge port, the third discharge port is open, that is, the second valve plate 35 does not close either discharge port; when the second discharge port closes both the second and third discharge ports, the first valve plate 34 can simultaneously close the first and second discharge ports, and the second and third discharge ports.

[0026] like Figure 3As shown, the telescopic drive mechanism 6 corresponding to the second feeding pipe 42 includes a telescopic driver 61, a traction rope 62, a mounting plate 63, a rotating shaft 64, pulleys 65, and a reversing wheel 66. The telescopic driver 61 is mounted on the hanger 12 and has two coaxial output ends. Each output end of the telescopic driver 61 is equipped with a pulley 65, and the telescopic driver 61 is used to drive the pulleys 65 to rotate. The mounting plate 63 is provided with a rotating shaft 64, and both ends of the rotating shaft 64 are provided with reversing wheels 66. Each pulley 65 on the telescopic drive is fixed with a traction rope 62, that is, there are two traction ropes 62. One end of each traction rope 62 is fixed to the corresponding pulley 65, and the pulley 65 is used to tighten or release the traction rope 62. The other end of the traction rope 62 passes around the reversing wheel 66 and is fixed to the telescopic dust cover 5. The traction rope 62 is used to pull up or lower the telescopic dust cover 5, so that the telescopic dust cover 5 is stretched or contracted. The telescopic actuator 61 drives the pulley 65 to rotate, and the rotation of the pulley 65 tightens or releases the traction rope 62. The traction rope 62 pulls up or down the telescopic dust cover 5. When the telescopic dust cover 5 is pulled up by the traction rope 62, it folds; when the telescopic dust cover 5 is lowered by the traction rope 62, it stretches, i.e., the telescopic dust cover 5 retracts. The lower end of the telescopic dust cover 5 falls into the graphite blank box 31, at which time it can fill the graphite blank. The telescopic drive mechanism 6 is set to continuously adjust the length of the telescopic dust cover 5 during the filling process of the graphite blank, so that the lower end of the telescopic dust cover 5 always maintains a small gap with the height difference between the lower end of the telescopic dust cover 5 and the powder in the graphite blank box 31, so as to reduce the generation of dust. There are two traction ropes 62, which facilitates the smooth pulling of the telescopic dust cover 5. The telescopic drive mechanism 6 is a double-end motor. The telescopic dust cover 5 adopts a corrugated telescopic dust cover 5 for dust use. Its structure is a conventional technology and will not be described in detail here. The telescopic drive mechanism 6 corresponding to the first feed pipe 41 and the third feed pipe 43 has no mounting plate 63, rotating shaft 64, pulley 65 and reversing wheel 66, and the other end of the traction rope 62 is directly connected to the telescopic dust cover 5.

[0027] like Figure 4As shown, the first feeding pipe includes a first guide pipe 411 and a first mounting pipe 412. The first guide pipe 411 guides the powder to the top of the corresponding graphite blank hopper 31. The upper end of the first guide pipe 411 is connected to the hopper 31 of the feeding switching device 3, i.e., the upper end of the first guide pipe 411 is installed at the first discharge port, and the lower end of the first guide pipe 411 is connected to the first mounting pipe 412. The first mounting pipe 412 is used to install a telescopic dust cover 5 and a negative pressure suction pipe 7. The upper end of the first mounting pipe 412 is connected to the negative pressure suction pipe 7, the first guide pipe 411 is connected to the middle of the first mounting pipe, and the lower end of the first mounting pipe 412 is connected to the telescopic dust cover 5. The first mounting pipe 412 is vertically arranged. The powder enters the first mounting pipe 412 from the first guide pipe 411 and then falls downwards along the first mounting pipe 412. The first mounting pipe 412 is provided to facilitate the installation of the telescopic dust cover 5 and the negative pressure suction pipe 7. The first mounting tube 412 is provided with two symmetrical through holes 441. The two through holes 441 are used for two traction ropes 62 to pass through. That is, after each traction rope 62 passes through the through hole 441, it is fixed to the lower end of the telescopic dust cover 5, which can prevent the traction rope 62 from being exposed.

[0028] like Figure 5 As shown, the second feeding pipe includes a second guide pipe 421 and a second mounting pipe 422. The second guide pipe 421 guides the powder to the upper part of the corresponding graphite blank hopper 31. The upper end of the second guide pipe 421 is connected to the hopper 31 of the feeding switching device 3, i.e., the upper end of the second guide pipe 421 is installed at the second discharge port, and the lower end of the second guide pipe 421 is connected to the second mounting pipe 422. The second mounting pipe 422 is used to install a telescopic dust cover 5 and a negative pressure suction pipe 7. The upper end of the second mounting pipe 422 is connected to the negative pressure suction pipe 7, the second guide pipe 421 is connected to the middle part of the second mounting pipe, and the lower end of the second mounting pipe 422 is connected to the telescopic dust cover 5. The second mounting pipe 422 is vertically arranged. The powder enters the second mounting pipe 422 from the second guide pipe 421 and then falls downwards along the second mounting pipe 422. The second mounting pipe 422 facilitates the installation of the telescopic dust cover 5 and the negative pressure suction pipe 7. The second mounting tube 422 is provided with two symmetrical through holes 441. The two through holes 441 are used for two traction ropes 62 to pass through. That is, after each traction rope 62 passes through the through hole 441, it is fixed to the lower end of the telescopic dust cover 5, which can prevent the traction rope 62 from being exposed.

[0029] like Figure 6As shown, the third feeding pipe includes a third guide pipe 431 and a third mounting pipe 432. The third guide pipe 431 guides the powder to the top of the corresponding graphite blank box 31. The upper end of the third guide pipe 431 is connected to the box 31 of the feeding switching device 3, i.e., the upper end of the third guide pipe 431 is installed at the third discharge port. The lower end of the third guide pipe 431 is connected to the third mounting pipe 432. The third mounting pipe 432 is used to install a telescopic dust cover 5 and a negative pressure suction pipe 7. The upper end of the third mounting pipe 432 is connected to the negative pressure suction pipe 7. The third guide pipe 431 is connected to the middle of the third mounting pipe 5. The lower end of the third mounting pipe 432 is connected to the telescopic dust cover 5. The third mounting pipe 432 is vertically arranged. The powder enters the third mounting pipe 432 from the third guide pipe 431 and then falls downwards along the third mounting pipe 432. A third mounting tube 432 is provided to facilitate the installation of the telescopic dust cover 5 and the negative pressure suction pipe 7. The third mounting tube 432 is provided with two symmetrical through holes 441, which are used for two traction ropes 62 to pass through. That is, after each traction rope 62 passes through the through hole 441, it is fixed to the lower end of the telescopic dust cover 5, which can prevent the traction rope 62 from being exposed.

[0030] When the first feeding pipe 41 needs to feed material, the switching driver 32 drives the shaft 33 to rotate. The rotation of the shaft 33 drives the first valve plate 34 and the second valve plate 35 to rotate, so that the second valve plate 35 closes the second and third discharge ports. The telescopic driver 61 of the telescopic drive mechanism 6 corresponding to the first feeding pipe 41 drives the pulley 65 to rotate. The pulley 65 releases the traction rope 62, so that the telescopic dust cover 5 falls into the corresponding graphite blank box 31. During the filling process, the telescopic driver 61 rotates in the opposite direction, driving the pulley 65 to rotate in the opposite direction to wind up the traction rope 62, so that the rear end of the traction rope 62 is pulled up, gradually or step by step folding the telescopic dust cover 5 until the graphite blank box 31 is filled. At this time, the telescopic dust cover 5 is just folded. After the filling is completed, the negative pressure suction pipe 7 starts to suck up the dust in the telescopic dust cover 5 and the first feeding pipe 41.

[0031] When the second feeding pipe 42 is needed, the switching driver 32 drives the shaft 33 to rotate. The rotation of the shaft 33 drives the first valve plate 34 and the second valve plate 35 to rotate, so that the first valve plate 34 closes the first outlet and the second valve plate 35 closes the third outlet. At the same time, the telescopic driver 61 of the telescopic drive mechanism 6 corresponding to the second feeding pipe 42 drives the pulley 65 to rotate. The pulley 65 releases the traction rope 62, so that the telescopic dust cover 5 falls into the corresponding graphite blank box 31. During the filling process, the telescopic driver 61 rotates in the opposite direction, driving the pulley 65 to rotate in the opposite direction to wind up the traction rope 62, so that the rear end of the traction rope 62 is pulled up, gradually or step by step folding the telescopic dust cover 5 until the graphite blank box 31 is filled. At this time, the telescopic dust cover 5 is just folded. After the filling is completed, the negative pressure suction pipe 7 starts to suck up the dust in the telescopic dust cover 5 and the second feeding pipe 42.

[0032] When the third feeding pipe 43 is needed, the switching driver 32 drives the shaft 33 to rotate. The rotation of the shaft 33 drives the first valve plate 34 and the second valve plate 35 to rotate, so that the first valve plate 34 closes the first and second discharge ports. The telescopic driver 61 of the telescopic drive mechanism 6 corresponding to the third feeding pipe 43 drives the pulley 65 to rotate. The pulley 65 releases the traction rope 62, so that the telescopic dust cover 5 falls into the corresponding graphite blank box 31. During the filling process, the telescopic driver 61 rotates in the opposite direction, driving the pulley 65 to rotate in the opposite direction to wind up the traction rope 62, so that the rear end of the traction rope 62 is pulled up, gradually or step by step folding the telescopic dust cover 5 until the graphite blank box 31 is filled. At this time, the telescopic dust cover 5 is just folded. After the filling is completed, the negative pressure suction pipe 7 starts to suck up the dust in the telescopic dust cover 5 and the third feeding pipe 43.

[0033] When it is necessary to switch the feeding position, simply switch the driver 32 to drive the first valve plate 34 and the second valve plate 35 to rotate. Then, the first feeding pipe 41, the second feeding pipe 42 or the third feeding pipe 43 can be selected for feeding according to the requirements. Changing the feeding position is convenient and quick. During the switching process, only the first valve plate 34 and the second valve plate 35 need to rotate. The first valve plate 34 and the second valve plate 35 are located inside the material box 31 and will not affect the outside. There is no need to switch by swinging, which improves safety.

[0034] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structures made using the contents of the present invention specification and drawings, whether directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of the present invention.
