Description

Technical Field

[0001] This utility model relates to the technical field of graphite material production equipment, specifically to a graphitization workshop feeding bin with water cooling function. Background Technology

[0002] The feeding silo in the graphitization workshop serves as an intermediate hub between the graphitization furnace and the front-end conveying equipment. It is used to temporarily store raw materials such as graphite powder to avoid production interruptions caused by mismatched feeding speeds.

[0003] In the prior art, a feeding hopper with patent publication number CN213009820U includes a hopper body, a screen, a cleaning hole, three fixed rubber plates, a sealing rubber plate, and four fixing strips. The cleaning hole is located on the hopper body, and the screen is inclined downwards inside the hopper body, with the lower edge of the screen protruding from the bottom of the cleaning hole. This device uses a screen inclined downwards inside the hopper body with rolled edges on three sides. The rolled edges cooperate with the fixed rubber plates and fixing strips to quickly assemble and disassemble the screen. The side of the screen without rolled edges extends outwards into the cleaning hole. The lower end of the sealing rubber plate is located at the lower end of the screen, and the upper end passes through the cleaning hole and is fixed to the outside of the hopper body. When it is necessary to clean waste, the upper end of the sealing rubber plate can be detached from the outside of the hopper body, and the upper end of the sealing rubber plate can be rotated downwards to a flat state. The waste then slides out of the cleaning hole along the sealing rubber plate, thereby achieving screening of raw materials entering the hopper body and convenient and quick waste cleaning.

[0004] In existing graphitization workshops, the feeding hoppers are mostly made of ordinary metal. The temperature during material conveying is usually high. High temperatures may cause the filter cartridge material to age or deform rapidly, resulting in a significant reduction in its service life, increased replacement frequency and maintenance costs. High temperatures may also accelerate the oxidation of the metal hopper, reducing structural strength and affecting the overall service life of the equipment. Furthermore, during the addition of graphite powder, there may be a defect where the material forms a wedge at the connection between the feed inlet and the hopper due to an excessive amount of graphite powder entering the feed inlet. Once a blockage occurs, the machine needs to be stopped to clean the feed inlet. The cleaning process not only consumes production time but may also reduce production capacity. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a water-cooled graphitization workshop feeding hopper, which can effectively solve the problems in existing technologies, such as the formation of accumulation wedges at the connection between the feed inlet and the hopper body due to excessive graphite powder inflow, and the rapid aging or deformation of filter cartridge materials due to high temperatures.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a feeding bin for a graphitization workshop with water cooling function, including a feeding bin body, including a double-layer water-cooled sandwich bin body, a feed inlet and a vent connected to the top of the double-layer water-cooled sandwich bin body, a water inlet and a water outlet connected to both sides of the double-layer water-cooled sandwich bin body, a discharge outlet connected to the bottom of the double-layer water-cooled sandwich bin body, and a plurality of spiral guide vanes welded to the inner wall of the double-layer water-cooled sandwich bin body.

[0008] The anti-blocking mechanism includes a blower assembly for preventing graphite powder raw material from entering the air inlet, a transmission assembly for transmitting the rotational power of the blower assembly, and a material distribution assembly for preventing excessive graphite powder raw material from entering the feed inlet simultaneously and forming a stacking wedge.

[0009] The blower assembly includes a motor adapted to be installed on the outside of the air inlet, a connecting rod fixedly connected to the output end of the motor via a coupling, and a universal joint fixedly installed on the other end of the connecting rod.

[0010] Furthermore, the blower assembly also includes a fan blade fixedly sleeved on the end of the universal joint away from the connecting rod, and a right-angle bracket fixedly connected to the inner surface of the double-layer water-cooled jacket and used in conjunction with the connecting rod.

[0011] Furthermore, the fan blade is located inside the breathing port, and a rotating bearing sleeve is installed at the connection between the connecting rod and the right-angle bracket.

[0012] Furthermore, the transmission assembly includes a first belt reel fixedly sleeved on the outer surface of the connecting rod, a synchronous belt sleeved on the outer surface of the first belt reel, a second belt reel sleeved on the inner surface of the other end of the synchronous belt, and a transmission rod fixedly connected to the outer end face of the second belt reel.

[0013] Furthermore, the transmission rod is fixedly mounted on the outer surface of the feed inlet via a bearing;

[0014] When the first pulley rotates with the connecting rod, it can drive the second pulley and the transmission rod to rotate synchronously through the synchronous belt.

[0015] Furthermore, the material distribution assembly includes a notched gear fixedly sleeved on the outer surface of the transmission rod, a driven gear meshing with the outer surface of the notched gear, a sector-shaped gear plate rotatably sleeved on the outer surface of the transmission rod and used in conjunction with the driven gear, and a tension spring fixedly installed on the outer surface of the sector-shaped gear plate.

[0016] Furthermore, the material distribution assembly also includes a rotating rod fixedly connected to the outer end face of the driven gear, and a material feeding disc fixedly installed at the through end of the rotating rod.

[0017] Furthermore, the outer end face of the feed disc is fixedly connected to the outer surface of the notched gear, and the sector tooth plate is used to ensure that the notched gear and the driven gear can mesh stably;

[0018] When the notched gear drives the driven gear to rotate, it can drive the sector tooth plate to rotate through the feed plate. When the notched gear rotates to the position where it disengages from the driven gear, the sector tooth plate rotates synchronously to the position where it meshes with the driven gear, and at the same time overcomes the elastic force of the tension spring to stop the sector tooth plate from rotating.

[0019] When the notched gear continues to rotate until it contacts the other side surface of the sector gear plate, it can drive the driven gear to rotate again.

[0020] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0021] This invention, through the coordinated operation of various components within the feeding hopper, not only significantly reduces material temperature and extends the service life of the filter cartridge, but also reduces energy consumption for cooling by utilizing recyclable cooling water. By incorporating an anti-clogging mechanism, it can drive the rotating rod and the feeding disc to rotate intermittently while generating airflow and maintaining stable air pressure within the hopper. This disperses the accumulated material at the feed inlet, preventing material from concentrating and causing blockage at the feed inlet, while also preventing graphite powder that has already passed through the feed inlet from being pushed back due to excessive rotation frequency of the feeding disc.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example: A water-cooled feeding hopper for a graphitization workshop, see attached figure. Figure 1 - Appendix Figure 6 ,include,

[0033] The feeding hopper body 100 includes a double-layer water-cooled sandwich hopper 110, a feed inlet 120 and a breather 130 connected to the top of the double-layer water-cooled sandwich hopper 110, a water inlet 140 and a water outlet 150 connected to both sides of the double-layer water-cooled sandwich hopper 110, a discharge outlet 160 connected to the bottom of the double-layer water-cooled sandwich hopper 110, and a plurality of spiral guide vanes 170 welded to the inner wall of the double-layer water-cooled sandwich hopper 110.

[0034] It should be noted that the inner layer of the double-layer water-cooled jacket 110 of the feeding hopper body 100 is made of high-temperature resistant stainless steel, and the outer layer is made of carbon steel. Circulating cooling water flows through the jacket, and through heat exchange, the material temperature can be reduced from 300℃ to below 150℃. The jacket water pressure is maintained at 0.3~0.5MPa to prevent localized vaporization and ensure cooling efficiency, thereby achieving rapid cooling of high-temperature materials and protecting the internal components of the feeding hopper body 100. The feed inlet 120 is used to receive and introduce graphite powder raw materials, which connects with the front-end conveying equipment. The material distribution component 230 is used to prevent excessive material inflow and the formation of accumulation wedges. A filter screen is fixedly connected to the connection between the breather 130 and the double-layer water-cooled jacket 110. This filter screen balances the air pressure inside the hopper, discharges dust-laden gas, and prevents dust from overflowing. When the air pressure inside the hopper increases, the gas carrying dust is discharged through the breather 130, where it is intercepted by the filter screen. When the air pressure decreases, outside air enters the hopper through the breather 130, and the rotation of the fan blades 214 of the blower component 210 further maintains the air pressure. The pressure is stable. Through the cooperation of the inlet 140 and the outlet 150, a cooling water circulation channel can be formed. Cooling water flows into the jacket from the inlet 140, absorbs heat in the chamber, and flows out from the outlet 150. After being cooled by an external circulation system, such as a centrifugal pump and a plate heat exchanger, it is reused. The discharge port 160 is used to transport the cooled graphite powder to the subsequent process. The spiral guide vane 170 is used to extend the heat dissipation path of the material, enhance heat exchange, and prevent material accumulation. Its inclination angle is 30° and the pitch is 50mm, thereby forcing the material to fall spirally along the chamber wall, so as to increase the contact time with the water-cooled jacket and ensure the uniform dispersion of the material. The feeding chamber body 100 is equipped with an audible and visual alarm, which is connected to the centrifugal pump through a temperature sensor and a PLC controller. When the temperature is abnormal, it can automatically alarm and cut off the feeding. The connection method of the audible and visual alarm, temperature sensor, PLC controller and centrifugal pump is existing technology, which will not be described in detail in this solution, and those skilled in the art can clearly understand its working principle.

[0035] The anti-blocking mechanism 200 includes a blower assembly 210 for preventing graphite powder raw material from entering the vent 130, a transmission assembly 220 for transmitting the rotational power of the blower assembly 210, and a distribution assembly 230 for preventing excessive graphite powder raw material from entering the feed inlet 120 at the same time and forming a stacking wedge.

[0036] The blower assembly 210 includes a motor 211 adapted to be installed on the outside of the air inlet 130, a connecting rod 212 fixedly connected to the output end of the motor 211 via a coupling, and a universal joint 213 fixedly installed on the other end of the connecting rod 212.

[0037] Specifically, the blower assembly 210 also includes a fan blade 214 fixedly sleeved on the end of the universal joint 213 away from the connecting rod 212, and a right-angle bracket 215 fixedly connected to the inner surface of the double-layer water-cooled sandwich chamber 110 and used in conjunction with the connecting rod 212.

[0038] It should be noted that when the motor 211 drives the connecting rod 212 to rotate, the connecting rod 212 can drive the fan blade 214 to rotate inside the air inlet 130 through the universal joint 213 and generate airflow to further maintain the stability of the air chamber pressure.

[0039] The right-angle bracket 215 fixes the connecting rod, and the bearing sleeve ensures smooth rotation.

[0040] Furthermore, the fan blade 214 is located inside the air inlet 130, and a rotating bearing sleeve is installed at the connection between the connecting rod 212 and the right-angle bracket 215.

[0041] Preferably, the transmission assembly 220 includes a first belt reel 221 fixedly sleeved on the outer surface of the connecting rod 212, a synchronous belt 222 sleeved on the outer surface of the first belt reel 221, a second belt reel 223 sleeved on the inner surface of the other end of the synchronous belt 222, and a transmission rod 224 fixedly connected to the outer end face of the second belt reel 223.

[0042] It should be noted that the transmission rod 224 is fixedly mounted on the outer surface of the feed inlet 120 by bearings;

[0043] When the first belt reel 221 rotates with the connecting rod 212, it can drive the second belt reel 223 and the transmission rod 224 to rotate synchronously via the synchronous belt 222.

[0044] Furthermore, the material distribution assembly 230 includes a notched gear 231 fixedly sleeved on the outer surface of the transmission rod 224, a driven gear 232 meshing with the outer surface of the notched gear 231, a sector toothed plate 233 rotatably sleeved on the outer surface of the transmission rod 224 and used in conjunction with the driven gear 232, and a tension spring 234 fixedly installed on the outer surface of the sector toothed plate 233.

[0045] Specifically, the material distribution assembly 230 also includes a rotating rod 235 fixedly connected to the outer end face of the driven gear 232, and a material feeding disc 236 fixedly installed at the through end of the rotating rod 235.

[0046] It should be further explained that when the first belt disc 221 rotates with the connecting rod 212, it can drive the second belt disc 223, the transmission rod 224, and the notched gear 231 to rotate synchronously via the synchronous belt 222. The notched gear 231, through its engagement with the driven gear 232, drives the rotating rod 235 and the material feeding disc 236 to rotate, causing the material feeding disc 236 to disperse the material accumulated in the feed inlet 120. When the notched gear 231 rotates to the point where it disengages from the driven gear 232, the elastic force of the fan-shaped toothed plate 233 overcomes the tension spring 234, causing it to stop rotating. When 231 continues to rotate to the position of contacting the other side surface of the sector toothed plate 233, it can drive the driven gear 232 to rotate again, ensuring stable gear meshing. At this time, the driven gear 232 is reset by the reaction force of the tension spring 234, and works with the notched gear 231 to drive the driven gear 232 to rotate again, thereby causing the feeding disc to rotate intermittently. This achieves the effect of preventing the material from rushing in and causing the feed inlet 120 to be blocked, while also preventing the graphite powder that has passed through the feed inlet 120 from being pushed back due to the excessive rotation frequency of the feeding disc 236.

[0047] Preferably, the outer end face of the feed disc 236 is fixedly connected to the outer surface of the notched gear 231, and the sector tooth plate 233 is used to ensure that the notched gear 231 and the driven gear 232 can mesh stably.

[0048] When the notched gear 231 drives the driven gear 232 to rotate, it can drive the sector tooth plate 233 to rotate through the feed plate 236. When the notched gear 231 rotates to the position where it disengages from the driven gear 232, the sector tooth plate 233 rotates synchronously to the position where it meshes with the driven gear 232, and at the same time overcomes the elastic force of the tension spring 234 to stop the sector tooth plate 233 from rotating.

[0049] When the notched gear 231 continues to rotate to a position that contacts the other side surface of the sector gear plate 233, it can drive the driven gear 232 to rotate again.

[0050] When using,

[0051] Graphite powder is fed into the feeding hopper body 100 through the inlet 120 by the front-end conveying equipment. Circulating cooling water is introduced through the high-temperature resistant stainless steel inner layer and the carbon steel outer layer of the double-layer water-cooled jacket hopper body 110, and the water pressure is maintained at 0.3~0.5MPa. The water flows in through the inlet 140 and, with the help of the inner wall spiral guide vanes 170, the material temperature is reduced from 300℃ to below 150℃. The spiral guide vanes 170 force the material to fall spirally with a 30° inclination angle and a 50mm pitch, extending the heat dissipation path and dispersing it evenly before it flows out through the outlet 150.

[0052] At the same time, the motor 211 is turned on to drive the connecting rod 212 to rotate. The connecting rod 212 drives the fan blade 214 to rotate inside the breathing port 130 through the universal joint 213 to generate airflow, so as to maintain the stability of the air pressure inside the chamber.

[0053] At the same time, the first belt disc 221 rotates with the connecting rod 212, and drives the second belt disc 223, the transmission rod 224 and the notched gear 231 to rotate synchronously through the synchronous belt 222;

[0054] The notched gear 231, through its cooperation with the driven gear 232, drives the rotating rod 235 and the material feeding disc 236 to rotate, breaking up the material piled up in the feed inlet 120;

[0055] When the notched gear 231 rotates to the position where it disengages from the driven gear 232, the sector toothed plate 233 rotates synchronously to the position where it engages with the driven gear 232. Under the force of the driven gear 232, the sector toothed plate 233 overcomes the force of the tension spring 234 and stops rotating, thereby stopping the rotation of the rotating rod 235 and the feeding disc 236. When the notched gear 231 rotates to contact the other side of the sector toothed plate 233, it can re-engage with the driven gear 232 through the sector toothed plate 233 and drive it to rotate. This causes the feeding disc 236 to rotate intermittently automatically, so as to prevent the material from rushing in and causing blockage of the feed inlet 120, while also preventing the graphite powder that has passed through the feed inlet 120 from being pushed back due to the excessive rotation frequency of the feeding disc 236.

[0056] The cooled graphite powder is finally conveyed from the discharge port 160 to the subsequent process.

[0057] In summary, through the coordinated operation of various components in the feeding hopper body 100, not only can the material temperature be significantly reduced, extending the service life of the filter cartridge, but the energy consumption required for cooling can also be reduced by recyclable cooling water. By setting up an anti-blocking mechanism 200, while driving the fan blades 214 to rotate and generate airflow to maintain stable air pressure inside the hopper, the rotating rod 235 and the material feeding disc 236 can be driven to rotate intermittently, breaking up the material accumulated in the feed inlet 120. This achieves the effect of preventing the material from rushing in and causing blockage of the feed inlet 120, while also preventing the graphite powder that has passed through the feed inlet 120 from being pushed back due to the excessive rotation frequency of the material feeding disc 236.

[0058] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
