Description

Technical Field

[0001] The utility model belongs to the technical field of graphite powder production equipment, in particular to an anti-blocking graphite powder discharging device. Background Art

[0002] Graphite, an allotrope of carbon, is a gray-black, opaque solid with stable chemical properties, corrosion resistance, and poor reactivity with acids and alkalis. It burns in oxygen to produce carbon dioxide, which can be oxidized by strong oxidants such as concentrated nitric acid and potassium permanganate. It is used as an anti-wear agent and lubricant. High-purity graphite is used as a neutron moderator in nuclear reactors. It is also used in the manufacture of crucibles, electrodes, brushes, dry cell batteries, graphite fibers, heat exchangers, coolers, arc furnaces, arc lamps, and pencil refills.

[0003] After the graphite mill grinds the graphite into powder, a discharging device is needed during the packaging process. Because the graphite powder has a very small particle size, it is easy for the friction between the particles to accumulate inside the storage during discharging, resulting in blockage of the storage outlet, affecting the storage discharge efficiency. Currently, when the storage outlet is blocked, the operator needs to poke the outlet open, but the graphite powder is too densely packed together, which is very easy to block the discharge port, resulting in poor discharge. The operator needs to manually clear the outlet multiple times, which reduces production efficiency. Utility Model Content

[0004] Based on the above background, the purpose of the present invention is to provide a graphite powder discharging device that is anti-clogging.

[0005] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0006] A blockage-resistant graphite powder discharging device comprises a material box, a discharge pipe is provided at the bottom of the material box, a feeding assembly is provided in the discharge pipe, the feeding assembly comprises a first rotating ring and a second rotating ring, the first rotating ring and the second rotating ring are respectively rotatably provided at the upper and lower ends of the inner side wall of the discharge pipe, the first rotating ring and the second rotating ring are connected by a first connecting rod, the first rotating ring is fixedly connected to a rotating shaft by the second connecting rod, the rotating shaft is coaxially arranged with the first rotating ring, and a spiral blade is provided on the surface of the rotating shaft;

[0007] The discharge pipe is provided with a driving assembly for driving the feeding assembly to rotate and feed the material in the discharge pipe;

[0008] The second connecting rod is provided with a material poking assembly, and the material poking assembly includes a sliding rod. The sliding rod is slidably arranged with the second connecting rod, and a material poking plate is provided on the top of the sliding rod.

[0009] Preferably, the driving assembly includes a first gear ring, which is rotatably connected to the discharge pipe. The first gear ring is fixedly sleeved on the outside of the first rotating ring. A motor is fixedly provided on the outside of the discharge pipe. The output end of the motor is fixedly connected to a driving wheel, and the driving wheel is meshed with the first gear ring.

[0010] Preferably, two first connecting rods are provided, which are symmetrically arranged with the axis of the first rotating ring as the center; a plurality of stirring blades are provided on the opposite side of the first connecting rod, and the stirring blades are evenly arranged on the side of the first connecting rod along the axis of the rotating shaft. During the rotation of the first connecting rod, the first connecting rod scrapes and disperses the graphite powder on the inner wall of the discharge pipe, and the stirring blades further disperse the scraped graphite powder to prevent the graphite powder from accumulating and clogging the discharge channel.

[0011] Preferably, the poke plate is a triangular plate, and the graphite powder can fall along the two sides of the triangular plate, which reduces the resistance of the poke plate and can better break up the graphite powder in the material box.

[0012] Preferably, a guide groove is provided on the inner wall of the discharge tube, and a third connecting rod is fixedly connected to the side wall of the slide rod, and the other end of the third connecting rod is slidably connected to the lower end surface of the guide groove. The guide groove is an irregular annular wave shape. During the rotation of the first rotating ring, one end of the third connecting rod slides along the lower end surface of the guide groove and moves up and down along the shape of the guide groove, thereby driving the slide rod to move up and down, and the poke plate moves back and forth up and down to dredge the graphite powder in the material box. Different parts of the graphite powder are dredged to different heights, and the bottom of the graphite powder is unevenly stressed, so it does not accumulate due to condensation, and the material is better discharged.

[0013] Preferably, the bottom of the slide rod is fixedly connected to a first limit plate, and the lower end of the slide rod is sleeved with a first spring, and both ends of the first spring are respectively fixedly connected to the first limit plate and the second connecting rod, and the width of the guide groove is greater than the width of the third connecting rod. When the slide rod moves up in the direction of the guide groove, the first spring is compressed. When it drops suddenly, the first spring vibrates due to the elastic restoring force, and the force of the slide rod moving up and down causes uneven breaking force of the graphite powder due to the elastic force, thereby destroying the graphite powder feeding path. The graphite powder is unevenly stressed and is not easy to accumulate, and will not block the channel due to too high density.

[0014] Preferably, a second limit plate is fixedly connected to the side of the slide rod, and a second spring is sleeved on the side of the slide rod. The two ends of the second spring are respectively fixedly connected to the second limit plate and the second connecting rod. When the first spring is compressed, the second spring is stretched. Under the action of the double elastic force, the frequency of the up and down vibration of the slide rod is increased, so that the graphite powder is better broken up and cleared.

[0015] Preferably, there are four second connecting rods distributed in a circular array along the circumference of the rotating shaft, and each second connecting rod is provided with a group of poke components. The four groups of poke components can better break up the graphite powder in the material box.

[0016] The utility model has the following beneficial effects:

[0017] 1. The utility model drives the first rotating ring, the second rotating ring and the first connecting rod to rotate through the driving assembly, thereby breaking up the graphite powder on the inner wall of the discharge pipe to avoid the graphite powder agglomeration and blocking the discharge channel due to too high density. At the same time, the graphite powder is transported by the rotation of the spiral blade to improve the discharge efficiency.

[0018] 2. The utility model drives the slide rod to rotate through the second rotating ring, and moves the slide rod up and down through the setting of the guide groove, the first spring and the second spring, so that the poke plate dredges the graphite powder in the material box. The graphite powder in different parts is dredged to different heights, and the bottom of the graphite powder is unevenly stressed, which is not easy to condense and accumulate, and the material is better discharged.

The first rotating ring 21 and the second rotating ring 22 are respectively rotatably arranged at the upper and lower ends of the inner side wall of the discharge pipe 11. The first rotating ring 21 and the second rotating ring 22 are connected by a first connecting rod 23. The first rotating ring 21 is fixedly connected to a rotating shaft 25 through a second connecting rod 24. The rotating shaft 25 is coaxially arranged with the first rotating ring 21, and a spiral blade 26 is provided on the surface of the rotating shaft 25.

[0035] Preferably, the driving assembly 3 includes a first gear ring 31, which is rotatably connected to the discharge tube 11. The first gear ring 31 is fixedly sleeved on the outside of the first rotating ring 21. A motor 33 is fixedly provided on the outside of the discharge tube 11. The output end of the motor 33 is fixedly connected to a driving wheel 32, and the driving wheel 32 is meshed with the first gear ring 31.

[0036] The motor 33 drives the driving wheel 32 to rotate, and the rotation of the driving wheel 32 drives the first gear ring 31 to rotate, and the first rotating ring 21 fixed to the inner wall of the first gear ring 31 rotates together, and the first gear ring 21 drives the second rotating ring 22 to rotate through the first connecting rod 23, and drives the rotating shaft 25 and the spiral blade 26 to rotate through the second connecting rod 24. The spiral blade 26 transports the graphite powder out of the discharge pipe 11 during the rotation, and the second connecting rod 24 rotates close to the inner wall of the discharge pipe 11 to break up the graphite powder on the inner wall of the discharge pipe 11 to avoid the graphite powder agglomeration and blocking the discharge channel due to too high density. During the rotation of the first rotating ring 21, the top slide bar 41 slides up and down, and the poke plate 42 breaks up the graphite powder in the material box 1 to avoid the graphite powder in the material box 1 from accumulating and being too dense to cause blockage and inability to fall normally, thereby improving the discharge efficiency of the graphite powder.

[0037] Preferably, two first connecting rods 23 are provided, which are symmetrically arranged with the axis of the first rotating ring 21 as the center; a plurality of stirring blades 27 are provided on the opposite side of the first connecting rod 23, and the stirring blades 27 are evenly arranged on the side of the first connecting rod 23 along the axial direction of the rotating shaft 25. During the rotation of the first connecting rod 23, the first connecting rod 23 scrapes and disperses the graphite powder on the inner wall of the discharge pipe 11, and the stirring blades 27 further disperse the scraped graphite powder to prevent the graphite powder from accumulating and clogging the discharge channel.

[0038] Preferably, the poke plate 42 is a triangular plate, and the graphite powder can fall along the two sides of the triangular plate, reducing the resistance of the poke plate 42 and better breaking up the graphite powder in the material box 1.

[0039] Preferably, a guide groove 43 is provided on the inner wall of the discharge tube 11, and a third connecting rod 44 is fixedly connected to the side wall of the slide rod 41. The other end of the third connecting rod 44 is slidingly connected to the lower end surface of the guide groove 43. The guide groove 43 is an irregular annular wave shape. During the rotation of the first rotating ring 21, one end of the third connecting rod 44 slides along the lower end surface of the guide groove 43 and moves up and down along the shape of the guide groove 43, thereby driving the slide rod 41 to move up and down, and the poke plate 42 moves back and forth up and down to dredge the graphite powder in the material box 1. Different parts of the graphite powder are dredged to different heights, and the bottom of the graphite powder is unevenly stressed, so it does not accumulate due to condensation, and the material is better discharged.

[0040] Preferably, a first limit plate 45 is fixedly connected to the bottom of the slide rod 41, and a first spring 46 is sleeved on the lower end of the slide rod 41. The two ends of the first spring 46 are respectively fixedly connected to the first limit plate 45 and the second connecting rod 24. The width of the guide groove 43 is greater than the width of the third connecting rod 44. When the slide rod 41 moves up in the direction of the guide groove 43, the first spring 46 is compressed. When it drops suddenly, the first spring 46 vibrates due to the elastic restoring force. The force of the slide rod 41 moving up and down causes uneven breaking force of the graphite powder due to the elastic force, which destroys the path of graphite powder discharge. The graphite powder is unevenly stressed and not easy to accumulate, and will not block the channel due to too high density.

[0041] Preferably, a second limit plate 47 is fixedly connected to the side of the slide rod 41, and a second spring 48 is sleeved on the side of the slide rod 41. The two ends of the second spring 48 are fixedly connected to the second limit plate 47 and the second connecting rod 24 respectively. When the first spring 46 is compressed, the second spring 48 is stretched. Under the action of the double elastic force, the frequency of the up and down vibration of the slide rod 41 is increased, so that the graphite powder is better broken up and cleared.

[0042] Preferably, four second connecting rods 24 are provided, which are distributed in a circular array along the circumference of the rotating shaft 25. A group of poke components 4 is provided on each second connecting rod 24. The four groups of poke components 4 can better break up the graphite powder in the material box.

[0043] The working principle of the utility model is as follows: the motor 33 drives the driving wheel 32 to rotate, and the rotation of the driving wheel 32 drives the first gear ring 31 to rotate, and the first rotating ring 21 fixed to the inner wall of the first gear ring 31 rotates together, and the first gear ring 21 drives the second rotating ring 22 to rotate through the first connecting rod 23, and drives the rotating shaft 25 and the spiral blade 26 to rotate through the second connecting rod 24. The spiral blade 26 transports the graphite powder out of the discharge pipe 11 during the rotation process, and the second connecting rod 24 rotates close to the inner wall of the discharge pipe 11 to break up the graphite powder on the inner wall of the discharge pipe 11. The stirring blade 27 further breaks up the scraped graphite powder to prevent the graphite powder from accumulating and blocking the discharge channel. During the rotation of the first rotating ring 21, one end of the third connecting rod 44 slides along the lower end surface of the guide groove 43 and moves up and down along the shape of the guide groove 43, thereby driving the slide rod 41 to move up and down. When the slide rod 41 moves up in the direction of the guide groove 43, the first spring 46 is compressed and the second spring 48 is stretched. When it drops suddenly, the first spring 46 and the second spring 48 vibrate due to the elastic restoring force. The force of the slide rod 41 moving up and down causes the graphite powder to be unevenly broken up due to the elastic force, thereby destroying the graphite powder discharge path. The graphite powder is unevenly stressed and not easy to accumulate, and will not be blocked by the high density. The discharge channel can be better unblocked, thereby improving the discharge efficiency.

[0044] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
