Description

Technical Field

[0001] This application relates to the field of carbon processing technology, specifically to a conveying mechanism and carbon production equipment. Background Technology

[0002] Carbon production equipment includes processes such as batching, mixing, and molding. The batching and mixing processes are connected by a conveying device to transport materials. The mixing process has a preheating pot and a mixing pot set up in sequence. The conveying device transports the materials to the preheating pot. After the materials are preheated, overheated, and stirred to a certain temperature, they are then introduced into the mixing pot. They are mixed and stirred with asphalt in the mixing pot for a certain period of time before entering the subsequent molding process.

[0003] Since the preheating pot takes time to heat the material to a certain temperature, and during this process, the preheating pot does not need to be fed, and the material conveying also takes a certain amount of time, the material conveying and heating are intermittent, resulting in low overall efficiency.

[0004] How to improve the production efficiency of carbon production equipment is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide a conveying mechanism and carbon production equipment that can effectively improve carbon production efficiency.

[0006] To solve the above-mentioned technical problems, this application provides a conveying mechanism for a carbon production equipment, including a conveying device, a first silo, and a distributing device arranged in sequence, wherein the distributing device is provided with at least one conveying port; it also includes a weighing device for detecting the weight of the material in the first silo, wherein the inlet of the first silo is provided with a first valve and the outlet of the first silo is provided with a second valve.

[0007] Optionally, it also includes a storage unit, which is connected between the conveying device and the first hopper.

[0008] Optionally, it also includes a second hopper, which is connected to the inlet of the conveying device, and a third valve is provided at the inlet of the second hopper.

[0009] Optionally, it also includes a support, which is disposed at the bottom of the first silo and is used to support the first silo, and the weighing device is disposed at the bottom of the support.

[0010] Optionally, the conveying device further includes a first heating unit for heating the material passing through the conveying device.

[0011] Optionally, the conveying device further includes a drive unit, a housing, and two parallel spiral shafts disposed within the housing. One end of the housing has a feed inlet, and the other end has a discharge outlet. Each spiral shaft is rotatably disposed within the housing and includes a shaft and blades. The blades extend spirally along the axial direction of the shaft, and the blades of the two spiral shafts are arranged alternately. The drive unit drives the shaft to rotate relative to the housing. Both the shaft and the blades are hollow structures, and the inner cavity of the shaft communicates with the inner cavity of the blades to form a heat exchange chamber. The spiral conveying mechanism also includes a connecting part. One end of the connecting part extends into the housing, and the other end of the connecting part is located outside the housing. The connecting part includes a first tube and a second tube that are sleeved together. The first tube is coaxially fixed with the rotating shaft, and the second tube is located inside the first tube, with one end of the second tube extending into the inner cavity of the rotating shaft. The first tube and the second tube form an annular cavity, and the annular cavity and the second tube are respectively connected to the heat exchange cavity to form a first heat exchange channel. The first heating part is connected to the first heat exchange channel through a medium pipeline, and the first heating part is used to heat the heat exchange medium passing through the medium pipeline.

[0012] Optionally, the driving unit includes a driving component, a transmission assembly, and two driving shafts. The two driving shafts are coaxially fixed to the two rotating shafts respectively. The driving component drives the two driving shafts to rotate synchronously through the transmission assembly, and the two driving shafts rotate in opposite directions.

[0013] Optionally, the housing is further provided with a cavity to form a second heat exchange channel, and the first heating part is also connected to the second heat exchange channel through a medium pipeline.

[0014] Optionally, the material dispensing device further includes a second heating section or a heat preservation section;

[0015] And / or, the side wall of the second hopper is also provided with an insulation layer.

[0016] This application also provides a carbon production equipment, including a batching device, a mixing device, and a molding device arranged in sequence, and a conveying mechanism as described above, wherein the conveying mechanism is disposed between the batching device and the mixing device.

[0017] The conveying mechanism and carbon production equipment provided in this application have the following technical advantages compared to the prior art:

[0018] Since the preheating pot needs a certain amount of time to stir and heat the material to the first preset temperature, during this time, the conveying device can continuously convey the material into the first hopper, so that the material is stored in the first hopper. The weight of the material in the first hopper can be detected by the weighing device, and the material in the first hopper can be controlled by the first valve and the second valve. When both the first valve and the second valve are closed, the material in the first hopper is the material with the preset weight.

[0019] The preset weight is determined based on the amount of material fed into the preheating pot in a single operation. Since the first hopper stores the preset weight of material, when the preheating pot needs to be fed, the required material can be quickly fed into the preheating pot through the first hopper without waiting for the conveying device. Furthermore, while the preheating pot is heating the material, although there is no need to feed material into the preheating pot, the first hopper allows the conveying device to continuously transport the material, ensuring that the material is continuously transported. This greatly shortens the waiting time caused by material transport, thereby improving production efficiency. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] This application provides a conveying mechanism for a carbon production equipment and the carbon production equipment itself. The carbon production equipment includes a batching device, a mixing device, and a molding device arranged in sequence. The batching device is used for batching materials and includes a batching scale and a verification scale bin arranged in sequence. The mixing device includes a preheating pot and a mixing pot arranged in sequence. A mixing valve is provided between the preheating pot and the mixing pot. The preheating pot is used to heat and stir the material so that the material reaches a first preset temperature. Then, the mixing valve is opened so that the material with the first preset temperature in the preheating pot is introduced into the mixing pot. After the material is mixed and stirred with asphalt in the mixing pot for a certain period of time, it is conveyed to the subsequent molding device for molding.

[0033] The carbon production equipment also includes a conveying mechanism, which is located between the batching device and the mixing device, and is used to transport the materials prepared by the batching device to the preheating pot of the mixing device.

[0034] like Figure 1 As shown, the conveying mechanism of the carbon production equipment is sequentially configured with a conveying device 100, a first silo 200, and a distributing device 800. The conveying device 100 is used to convey the materials prepared by the batching device to the first silo 200. When the mixing device needs to feed materials, the distributing device 800 distributes the materials in the first silo 200 to the corresponding conveying ports.

[0035] The conveying mechanism also includes a weighing device 300, which is used to detect the weight of the material in the first hopper 200.

[0036] The inlet of the first silo 200 is equipped with a first valve 210, and the outlet of the first silo 200 is equipped with a second valve 220. When the first valve 210 is open and the second valve 220 is closed, the conveying device 100 can convey materials into the first silo 200 through the inlet of the first silo 200. The weighing device 300 is used to detect the amount of material in the first silo 200. When the amount of material in the first silo 200 reaches the preset weight, the first valve 210 can be closed. When the kneading device needs to feed materials, the first valve 210 is closed and the second valve 220 is opened. The first silo 200 can be fed into the preheating pot of the kneading device through the distributing device 800. The amount of material in the first silo 200 can be controlled by the first valve 210 and the second valve 220.

[0037] After the material is fed into the preheating pot, the preheating pot can stir and heat the material. When the material reaches the first preset temperature, the kneading valve opens, and the material with the first preset temperature in the preheating pot enters the kneading pot. At this time, the preheating pot is emptied, the kneading valve closes, and when the material is fed again, the second valve 220 opens, and the material with the preset weight stored in the first hopper 200 is fed into the preheating pot again through the distributing device 800 to participate in stirring and heating.

[0038] Since the preheating pot needs a certain amount of time to stir and heat the material to the first preset temperature, during this time, the conveying device 100 continuously conveys the material into the first hopper 200, so that the material is stored in the first hopper 200. The weighing device 300 can detect the weight of the material in the first hopper 200, and the material in the first hopper 200 can be controlled by the first valve 210 and the second valve 220. When both the first valve 210 and the second valve 220 are closed, the material in the first hopper 200 is the material with the preset weight.

[0039] The preset weight is determined based on the amount of material fed into the preheating pot in a single operation. Since the first hopper 200 stores the preset weight of material, when the preheating pot needs to be fed, the required material can be quickly fed into the preheating pot through the first hopper 200 without waiting for the conveying device 100 to deliver it. Furthermore, although there is no need to feed material into the preheating pot while it is heating the material, the first hopper 200 allows the conveying device 100 to continuously deliver the material, ensuring that the material is continuously conveyed. This greatly shortens the waiting time caused by material delivery and thus improves production efficiency.

[0040] like Figure 1As shown, the conveying mechanism also includes a storage section 400, which is connected between the conveying device 100 and the first hopper 200. The storage section 400 is used to temporarily store materials. When the weight of the material in the first hopper 200 reaches a preset weight, the first valve 210 closes. At this time, materials are no longer conveyed into the first hopper 200, and the conveying device 100 can continue to convey materials to the storage section 400. When the material in the first hopper 200 is emptied, the first valve 210 opens, and the material in the storage section 400 directly enters the first hopper 200. The material conveyed by the conveying device 100 also enters the first hopper 200 for storage through the storage section 400.

[0041] The storage section 400 allows for the temporary storage of materials output from the conveying device 100 when the first valve 210 is closed, enabling the conveying device 100 to continuously transport materials, increasing the efficiency of the output device 100, and eliminating the need for frequent opening and closing of the conveying device 100, thereby reducing the probability of malfunctions and extending its service life.

[0042] There are no restrictions on the structure of the storage section 400. For example, it can be set as a box, with the aforementioned first valve 210 installed between the outlet of the box and the inlet of the first hopper 200. Alternatively, the storage section 400 can be set as a storage pipe to simplify the overall structure.

[0043] like Figure 1 As shown, the conveying mechanism also includes a second hopper 500, which is connected between the verification weighing hopper and the inlet of the conveying device 100. The second hopper 500 is connected to the inlet of the conveying device 100, and a third valve is also provided at the inlet of the second hopper 500. The batching scale is used for batching and the batched material flows through the pipeline to the verification weighing hopper. The verification weighing hopper is used to verify the weight of the material. Then, the verified material can be fed into the second hopper 500. After the third valve is closed, the batching device can start the next batching operation.

[0044] The batching device is used to prepare materials with a preset weight. When the preset weight of materials is prepared and the materials in the first hopper 200 are discharged, the second valve 220 is closed and the first valve 210 is opened. At the same time, the third valve is opened, and the verification hopper feeds the preset weight of materials into the second hopper 500. That is to say, the conveying mechanism discharges the preset weight of materials through the first hopper 200 each time, and at the same time, the batching device also feeds the preset weight of materials into the second hopper 500 to ensure the material balance in the conveying mechanism.

[0045] Both the first silo 200 and the second silo 500 are used to store materials. The conveying device 100 maintains a continuous material conveying state, thereby ensuring the overall stable operation of the carbon production equipment while reducing the waiting time caused by the batching device, the preheating pot of the mixing device, and the conveying device 100 conveying materials. The batching device, the conveying device 100, and the preheating pot can all be carried out simultaneously, thereby effectively improving the utilization efficiency of each component of the carbon production equipment and increasing production efficiency.

[0046] The structure of the first hopper 200 can be as follows: Figure 1 As shown, a guide surface is provided at the bottom to ensure that the material in the first hopper 200 is completely fed into the mixing device after the second valve 220 is opened, thus preventing material from accumulating in the first hopper 200 and causing insufficient or excessive material to enter the mixing device. The guide surface can be either a conical surface or an inclined surface.

[0047] In this embodiment, the structure of the weighing device 300 is not limited, such as... Figure 1 In the illustrated embodiment, a support 600 is also provided at the bottom of the first hopper 200. The support 600 supports the first hopper 200 from the bottom. The weighing device 300 is located between the bottom of the support 600 and the ground or platform to detect the weight of the material in the first hopper 200. Alternatively, the weighing device 300 can be located at the second valve 220. By constructing a support for the first hopper 200 and placing the weighing device 300 at the bottom of the support 600, the stability of the first hopper 200 can be ensured, as well as the accuracy of the weight detection of the material.

[0048] The conveying mechanism also includes a frame 900, a conveying device 100 and a batching device located above the frame 900, a second hopper 500 located above the feed inlet of the conveying device 100, a verification weighing hopper located above the second hopper 500, a storage section 400, a first hopper 200, a distribution valve 700 and a conveying section 800 sequentially located below the discharge outlet of the conveying device 100, and a preheating pot and a mixing pot sequentially located below the conveying outlet of the conveying section 800 to facilitate material feeding.

[0049] The conveying device 100 also includes a first heating section, which is used to heat the material passing through the conveying device 100 so that the material has been raised to a certain temperature before reaching the preheating pot. The material can be quickly heated to a first preset temperature in the preheating pot, shortening the residence time of the material in the preheating pot and thus improving production efficiency.

[0050] like Figure 2 and Figure 3As shown, the conveying device 100 also includes a drive unit 5, a housing 1, and two parallel spiral shafts 2 disposed inside the housing 1. One end of the housing 1 is provided with a feed inlet, and the other end of the housing 1 is provided with a discharge outlet. The spiral shafts 2 are rotatably disposed inside the housing 1. The spiral shafts 2 include a rotating shaft 21 and blades 22. The blades 22 extend spirally along the axial direction of the rotating shaft 21. The blades 22 of the two spiral shafts 2 are staggered. The two spiral shafts 2 rotate in opposite directions and can convey the material entering the housing 1 from the feed inlet to the discharge outlet side, so that the material is discharged from the discharge outlet, thereby realizing the conveying of material from the feed inlet to the discharge outlet side. The drive unit 5 is used to drive the rotating shaft 21 to rotate relative to the housing 1.

[0051] In other words, the conveying device 100 is a double spiral conveying device. Of course, in this embodiment, the specific structure of the conveying device 100 is not limited. For example, it can also be set as a conveyor belt conveyor. The material conveyed by the spiral conveying device 100 can also be stirred to improve the mixing effect of the material, make the material heat evenly, and facilitate the control of the material conveying amount.

[0052] Both the shaft 21 and the blade 22 are hollow structures, and the inner cavity of the shaft 21 is connected to the inner cavity of the blade 22 to form a heat exchange chamber. For example... Figure 4 As shown, the conveying device also includes a connecting part 3. One end of the connecting part 3 extends into the housing 1, and the other end of the connecting part 3 is located outside the housing 1. The connecting part 3 includes a first tube part 31 and a second tube part 32 that are sleeved together. The first tube part 31 is sleeved outside the second tube part 32. The first tube part 31 is coaxially fixed with the rotating shaft 21. The second tube part 32 is located inside the first tube part 31, and one end of the second tube part 32 extends into the inner cavity of the rotating shaft 21. The first tube part 31 and the second tube part 32 form an annular cavity 33. The inner cavities of the annular cavity 33 and the second tube part 32 are respectively connected to the heat exchange cavity, thereby forming a first heat exchange channel. In the inner cavities of the annular cavity 33 and the second tube part 32, one forms an inlet channel for the heat exchange medium, and the other forms an outlet channel for the heat exchange medium.

[0053] The first heating section is connected to the first heat exchange channel through the medium pipeline 8. The first heating section is used to heat the heat exchange medium passing through the medium pipeline 8. The heated heat exchange medium can enter through the inlet channel, and after passing through the heat exchange chamber (which includes the inner cavity of the rotating shaft 21 and the inner cavity of the blade 22) and exchanging heat with the material in the shell 1, it can be discharged through the outlet channel and heated again by the first heating section, thereby enabling the conveying device 100 to have heat exchange performance.

[0054] In other words, the conveying device 100 provided in this embodiment can exchange heat with the material through a heat exchange medium during the material conveying process, which can effectively increase the temperature of the material, reduce the heating requirements of the subsequent preheating pot, and improve production efficiency.

[0055] The drive unit 5 includes a drive shaft 51 and a drive component 52. The drive shaft 51 is connected to the rotating shaft 21 and the two can rotate synchronously. The drive component 52 is used to drive the drive shaft 51 to rotate and drive the rotating shaft 21 to rotate, so as to realize the conveying of materials.

[0056] like Figure 4 As shown, one end of the drive shaft 51 is located inside the rotating shaft 21. The end of the drive shaft 51 is fixed to the inner wall of the rotating shaft 21 by a fixing member 25. The fixing member 25 has a hollow structure to facilitate the passage of the heat exchange medium and avoid obstructing the heat exchange medium inside the rotating shaft 21, thereby ensuring the heat exchange effect. Furthermore, the ends of the drive shaft 51 and the rotating shaft 21 are also sealed and fixed along the circumference of the drive shaft 51.

[0057] In other words, one end of the drive shaft 51 extends into the rotating shaft 21, and the drive shaft 51 is fixed at the end of the rotating shaft 21 and at the fixing member 25, respectively, to ensure the stability of the fixing between the rotating shaft 21 and the drive shaft 51, thereby ensuring the stability of the drive unit 5 driving the rotating shaft 21 to rotate through the drive shaft 51.

[0058] The drive unit 5 also includes a transmission assembly 53. The drive member 52 can simultaneously drive two drive shafts 51 to rotate via the transmission assembly 53, and the two drive shafts 51 rotate in opposite directions. Of course, the transmission assembly 53 can also be omitted, and the two drive members 52 can drive the two drive shafts 51 to rotate separately. However, by setting the transmission assembly 53, one drive member 52 can synchronously drive the two drive shafts 51 to rotate, which provides good synchronization and can further simplify the overall structure and reduce costs.

[0059] The transmission assembly 53 may include two meshing synchronous gears, which are coaxially fixed to two drive shafts 51 respectively. The drive component 52 includes a motor that is driveably connected to one of the drive shafts 51. Of course, in this embodiment, the specific structure of the transmission assembly 53 is not limited. For example, the transmission assembly 53 may be configured to include a drive shaft, a drive gear, and two driven gears. The motor is driveably connected to the drive shaft, the drive gear is coaxially fixed to the drive shaft, and the two driven gears are coaxially fixed to the two drive shafts respectively. One driven gear directly meshes with the drive gear, and an intermediate gear is provided between the other driven gear and the drive gear to achieve opposite rotation directions of the two drive shafts.

[0060] By configuring the transmission assembly 53 to include two directly meshing synchronous gears, the overall structure can be simplified and spatial arrangement can be facilitated. The drive component 52 may also include components such as a reducer, which can be configured according to the actual situation.

[0061] The drive unit 5 and the connecting unit 3 are located on the axial sides of the housing 1, respectively. The heat exchange medium enters and exits the heat exchange chamber through the connecting unit 3. In other words, the entry and exit of the heat exchange medium are both located on the same axial side of the conveying device 100, which can avoid interference between the medium pipeline and the drive unit 5, facilitate on-site layout, and reduce the requirements for installation space.

[0062] Furthermore, by placing both the inlet and outlet channels on the same axial side of the housing 1, compared to placing them at opposite axial ends of the housing 1, it is easier to install the first heating element. The first heating element is connected to the inlet and outlet channels via the medium pipeline 8. Placing both the inlet and outlet channels on the same axial end of the housing 1 facilitates the arrangement of the first heating element and the medium pipeline 8, thereby simplifying the overall structure.

[0063] The first tube 31 is fixed coaxially with the rotating shaft 21 and rotates synchronously with the rotating shaft 21. The second tube 32 is sleeved inside the first tube 31. A gap is left between the second tube 32 and the first tube 31 to form an annular cavity 33. The second tube 32 does not need to rotate to simplify the external communication structure.

[0064] In this embodiment, there are no restrictions on the heat exchange medium; it can be water, oil, steam, etc.

[0065] like Figure 4 As shown, when the heat exchange medium is a liquid medium such as water or oil, the annular cavity 33 formed by the first tube section 31 and the second tube section 32 is connected to the inner cavity of the blade 22, and the inner cavity of the second tube section 32 is connected to the inner cavity of the rotating shaft 21.

[0066] Taking the annular cavity 33 forming an inlet channel and the inner cavity of the second tube 32 forming an outlet channel as an example, after the heat exchange medium enters the inner cavity of the blade 22 through the inlet channel, it flows along the inner cavity of the blade 22 to the inner cavity of the rotating shaft 21, and finally flows out through the outlet channel.

[0067] Of course, in this embodiment, the inner cavity of the second tube 32 can be connected to the inner cavity of the blade 22, and the annular cavity 33 can be connected to the inner cavity of the rotating shaft 21. However, connecting the inner cavity of the second tube 32 sleeved on the inner side to the inner cavity of the rotating shaft 21, and connecting the outer annular cavity 33 to the inner cavity of the blade 22, makes the overall structure arrangement more convenient.

[0068] A first connecting port 211 is provided on the side wall of the rotating shaft 21 away from the connecting part 3. The inner cavity of the blade 22 and the inner cavity of the rotating shaft 21 are connected through the first connecting port 211. After the heat exchange medium enters the inner cavity of the blade 22, it flows spirally along the inner cavity of the blade 22 to the side away from the connecting part 3, and then enters the inner cavity of the rotating shaft 21 through the first connecting port 211. After flowing to the side of the rotating shaft 21 facing the connecting part, it is discharged from the second pipe 32. This arrangement ensures that the heat exchange medium can completely pass through the inner cavity of the blade 22 and the inner cavity of the rotating shaft 21, ensuring the overall heat exchange effect at all positions in the axial direction of the conveying device 100.

[0069] like Figure 4 As shown, a partition 23 is also provided inside the rotating shaft 21. The partition 23 can divide the inner cavity of the rotating shaft 21 into a first cavity 213 and a second cavity 214. The first cavity 213 is provided on the side facing the connecting part 3. The first cavity 213 is connected to the inner cavity of the blade 22 and the annular cavity 33. The second cavity 214 is connected to the inner cavity of the second tube part 32.

[0070] Alternatively, in this embodiment, the annular cavity 33 can be connected to the inner cavity of the blade 22 through a connecting pipe. By setting a partition 23 to form a first cavity 213 and a second cavity 214, and by using the first cavity 213 to achieve the connection between the annular cavity 33 and the inner cavity of the blade 22, the overall structure can be simplified and the connection stability can be improved.

[0071] The partition 23 is fixed to the inner wall of the rotating shaft 21. The specific fixing method is not limited, such as interference fit. The partition 23 is also fixed to the end of the first tube 31. The side wall of the first tube 31 is provided with a second communication port 212, which communicates with the first cavity 213. The heat exchange medium flows sequentially through the annular cavity 33, the second communication port 212, the first cavity 213, the first communication port 211, the inner cavity of the blade 22, the second cavity 214, and the second tube 32.

[0072] Of course, in this embodiment, there may also be a gap between the end of the first tube 31 and the partition 23, so that the medium in the annular cavity 33 can enter the first cavity 213 from the end of the first tube 31. When the end of the first tube 31 is fixed to the partition 23, the end of the first tube 31 is fixed to the rotating shaft 21. At the same time, the first tube 31 is also fixed to the rotating shaft 21 through the partition 23, so as to ensure the stability of the fixation between the first tube 31 and the rotating shaft 21.

[0073] The end of the second tube 32 can extend out of the partition 23, or it can be aligned with the partition 23. The second tube 32 and the partition 23 can be fitted with a small gap to ensure relative rotation between them.

[0074] like Figure 5As shown, when the heat exchange medium is a liquid medium such as high-temperature steam, the two medium channels are respectively connected to the inner cavity of the rotating shaft 21. That is, the annular cavity 33 and the second tube section 32 are both connected to the inner cavity of the rotating shaft 21. Multiple connecting pipes 24 are also spaced apart on the side wall of the rotating shaft 21. One end of each connecting pipe 24 is connected to the inner cavity of the blade 22, and the other end of the connecting pipe 24 is positioned towards the inner side of the inner cavity of the rotating shaft 21. This can be as follows: Figure 5 As shown, the connecting pipe 24 is arranged approximately in the radial direction of the rotating shaft 21, and the second pipe section 32 is provided with a bent section 321 at one end inside the rotating shaft 21, which is arranged towards the bottom of the rotating shaft 21.

[0075] The second tube 32 does not rotate with the shaft 21. The bent portion 321 of the second tube 32 is positioned facing the bottom of the shaft 21. The bottom of the shaft 21 refers to the side of the shaft 21 facing downwards when it is in the installed state.

[0076] After the high-temperature steam enters the heat exchange chamber along the annular cavity 33, it can enter the inner cavity of the blade 22 through the connecting pipe 24 from the inner cavity of the rotating shaft 21 and fill the entire heat exchange chamber. After the high-temperature steam exchanges heat with the external material in the heat exchange chamber, the temperature decreases and some of the steam condenses to form water droplets.

[0077] The inner cavity of the blade 22 is also provided with a guide structure 221. The guide structure 221 can be a guide plate or a guide groove, etc. The guide structure 221 is used to guide the water droplets in the inner cavity of the blade 22 to the connecting pipe 24. When the blade 22 rotates to the end of the connecting pipe 24 (the end facing the inside of the rotating shaft 21) and tilts downward, the water in the blade 22 will flow along the connecting pipe 24 to the rotating shaft 21. Under the action of gravity, the water in the rotating shaft 21 falls to the bottom. When the water accumulates to a certain amount, it can submerge the end of the second pipe section 32. As high-temperature steam continues to enter, the pressure in the heat exchange chamber increases, and the water is discharged from the second pipe section 32.

[0078] The specific shape and structure of the guide structure 221 are not limited. For example, the guide structure 221 can be set as a water-blocking groove arranged inside the blade 22 along the outer periphery of the rotating shaft 21. The water-blocking groove is located close to the connecting pipe 24, and the groove opening faces the connecting pipe 24. The connecting pipe 24 is located on the side of the water-blocking groove facing the rotation direction of the rotating shaft 24, so that... Figure 6 and Figure 7 As shown, when the water-blocking trough is in the low position, it can store water as the rotating shaft 21 rotates. When the water-blocking trough rotates to the high position, it can discharge the internal water into the rotating shaft 21 through the inclined connecting pipe 24. Alternatively, the guide structure can be set as a baffle. As the rotating shaft rotates, the baffle can carry at least part of the water to the high position and discharge the water into the rotating shaft 21 through the inclined connecting pipe 24.

[0079] Of course, in this embodiment, the inner cavity of the rotating shaft 21 and the inner cavity of the blade 22 can also be set to be completely connected, that is, the rotating shaft 21 and the blade 22 are not separated by the side wall of the rotating shaft 21, and the wall surface of the inner cavity of the spiral shaft 2 conforms to the outer wall surface of the spiral shaft 2. In this case, the annular cavity 33 can be connected to the end of the inner cavity of the spiral shaft 2 facing the connecting part 3, and the second tube 32 can be extended to the side end of the inner cavity of the spiral shaft 2 away from the connecting part 3.

[0080] Separating the inner cavity of the blade 22 from the inner cavity of the rotating shaft 21 ensures the overall structural strength of the spiral shaft 2 and simplifies the molding process.

[0081] like Figure 8 As shown, the conveying device 100 also includes a rotary joint 4, which is located outside the housing 1 and connected to the connecting part 3. The rotary joint 4 can be a conventional rotary joint 4, the structure of which is well known to those skilled in the art and will not be described in detail here for the sake of brevity. The rotary joint 4 includes an outer tube 41 and an inner tube 42, wherein the outer tube 41 and the inner tube 42 can rotate relative to each other. The outer tube 41 is coaxially fixed and connected to the first tube part 31, and the outer tube 41 can rotate together with the first tube part 31 and the spiral shaft 2. The inner tube 42 is coaxially fixed and connected to the second tube part 32, or the inner tube 42 and the second tube part 32 can be integrally formed.

[0082] Of the outer tube 41 and the inner tube 42, one forms an inlet tube and the other forms an outlet tube. The outer tube 41 and the inner tube 42 are respectively connected to the first heating unit through the medium pipeline 8. The rotary joint 4 is provided to facilitate connection with the first heating unit.

[0083] The method of fixing the outer tube 41 and the first tube section 31 is not limited, such as... Figure 8 As shown, the outer tube 41 is provided with a first flange 311, and the first tube section 31 is provided with a second flange 411. The first flange 311 and the second flange 411 are fixed by bolts, which provides good stability and facilitates installation and operation, reducing the structural requirements of the outer tube 41. Of course, the outer tube 41 and the first tube section 31 can also be made into an integral structure.

[0084] Of course, in this embodiment, the rotary joint 4 may not be provided. Instead, a connecting part is provided, which has a connecting cavity. The end of the first tube 31 away from the rotating shaft 21 extends into the connecting cavity and communicates with it. The first tube 31 can rotate relative to the connecting part, while the connecting part does not rotate with the rotating shaft 21. The connecting part can be connected to the first heating part through the medium pipeline 8.

[0085] The conveying device 100 also includes a bracket 6, which is fixed to the side of the housing 1 facing the connecting part 3. A bearing 7 is also provided between the first tube 31 of the connecting part 3 and the bracket 6. The bracket 6 provides support to the connecting part 3, thereby providing support to the side of the rotating shaft 21 facing the connecting part 3 and ensuring support stability.

[0086] A bracket 6 may also be provided on the side of the housing 1 facing the drive unit 5. A bearing 7 is provided between the bracket 6 and the drive shaft 51 to ensure the rotational stability of the drive shaft 51.

[0087] In this embodiment, the sidewall of the shell 1 is also provided with a cavity, and a second heat exchange channel is formed through the cavity. The wall of the shell 1 can be provided with a serpentine arrangement of cavities, or the inner wall of the shell 1 can be an entire cavity structure. The first heat exchange channel and the second heat exchange channel can be arranged in series, or the first heat exchange channel and the second heat exchange channel can be arranged in parallel and respectively connected to the first heating part through the medium pipeline 8; or the first heating part can also include two heating elements, and the two heating elements can be respectively arranged corresponding to the first heat exchange channel and the second heat exchange channel.

[0088] The second heat exchange channel on the side wall of the shell 1 can be arranged on a local side wall of the shell 1, or all side walls of the shell 1 can be provided with cavities. The specific arrangement can be determined according to the structure of the shell 1 and the connection and placement of the shell 1 with other external components, etc., and no specific restrictions are imposed here.

[0089] like Figure 2 and Figure 3 As shown, the shell 1 is provided with a medium inlet 11 and a medium outlet 12. The medium inlet 11 is located above the side wall of the shell 1, and the medium outlet 12 is located on the bottom wall of the shell 1. Due to structural limitations, the top of the shell 1 is not provided with a second heat exchange channel. The two sides of the shell 1 are respectively provided with medium inlets 11. The heat exchange medium enters the second heat exchange channel through the medium inlet 11 and exchanges heat with the material in the shell 1. After that, it is discharged through the medium outlet 12. It can be re-entered into the second heat exchange channel through the medium inlet 11 after being heated by the first heating part to participate in heat exchange again.

[0090] Of course, the medium inlet 11 can also be located on the bottom wall of the housing 1, and the medium outlet 12 can be located on the upper side wall of the housing 1. No specific restrictions are made here.

[0091] The side wall of the second silo 500 is also provided with an insulation layer. The material conveyed to the second silo 500 by the conveying device 100 has a certain temperature. The insulation layer can reduce the heat exchange between the material in the second silo 500 and the external environment, thereby reducing heat loss.

[0092] In this embodiment, there are no restrictions on the valve components (including the first valve component 210, the second valve component 220 and the third valve component), the mixing valve, and the valve section 850. For example, a slide gate valve or the like can be used.

[0093] The working principle of the carbon production equipment provided in this embodiment is as follows:

[0094] When the first valve 210 is in the open position and the third valve is open, and the second valve 220 is closed, the batching scale will send the material through the pipeline to the verification weighing bin, the second silo 500, the conveying device 100, and the first silo 200 in sequence. When the weighing device 300 detects that the material in the first silo 200 has reached the preset weight, the first valve 210 will close, and the third valve can also close, so that the first silo 200 in the conveying mechanism stores the preset weight of material, while the conveying device 100 and the second silo 500 also retain a certain amount of material.

[0095] When the mixing device needs to be fed, the second valve 220 opens, and the material in the first hopper 200 is conveyed to the corresponding preheating pot through the distributing device 800. When the weighing device 300 detects that the material in the first hopper 200 has been completely discharged, the second valve 220 closes, and then the first valve 210 opens, and the material in the storage section 400 is fed into the first hopper 200. The conveying device 100 continues to feed material into the first hopper 200 until the detection device detects that the amount of material in the first hopper 200 has reached the preset weight, at which point the first valve 210 closes.

[0096] With the first valve 210 open, the conveying device 100 feeds material into the first hopper 200. At the same time, the third valve also opens, and the verification weighing hopper feeds a preset weight of material into the second hopper 500 to ensure the balance of material quantity within the conveying mechanism. Because the verification weighing hopper discharges material quickly, after all the material in the verification hopper has been fed into the second hopper 500, the third valve closes, and the verification weighing hopper proceeds to the next round of feeding. Meanwhile, the conveying device 100 continues to convey material. Due to the relatively slow material conveying speed of the conveying device 100, some material still accumulates in the second hopper 500, waiting to be discharged. During the conveying process of the conveying device 100, the material exchanges heat with the heat exchange medium, causing its temperature to rise. The heated material is then discharged from the outlet of the conveying device 100 into the first hopper 200.

[0097] When the first valve 210 is closed, the conveying device 100 continuously conveys material to the storage section 400, where the material is temporarily stored. During this process, the conveying device 100 can reduce the material conveying speed as needed. When the first valve 210 is opened, the conveying device 100 resumes a higher conveying speed. Alternatively, if the first valve 210 remains closed after the conveying device 100 reduces the material conveying speed and operates for a period of time (e.g., 5 minutes or 10 minutes), the conveying device 100 stops conveying material, meaning the drive unit 52 stops driving the rotating shaft 21 to rotate. After the first valve 210 is opened, the drive unit 52 drives the rotating shaft 21 to rotate again, and the conveying device 100 continues conveying material.

[0098] The material distribution device 800 is provided with at least one conveying port, each conveying port corresponds to a kneading device, and each conveying port is provided with a valve part 850. The material distribution device 800 is used to convey the material discharged from the first hopper 200 to the corresponding kneading device through the conveying port.

[0099] When there are many mixing devices, the material distribution device 800 also includes a material distribution valve 700 and a conveying unit 800. The material distribution valve 700 can be a three-way valve or other multi-way valve. The material distribution valve 700 is connected to the discharge port of the first silo 200 and each conveying unit 800 respectively.

[0100] The conveying unit 800 conveys materials at a relatively fast speed. The conveying unit 800 can be a screw conveyor or a belt conveyor, etc. There are no specific restrictions here. When the second valve 220 is closed, the first hopper 200 finishes discharging. At this time, the conveying unit 800 can automatically stop after a preset time (such as 1 minute, 3 minutes, etc.). The material has been completely conveyed by the conveying unit 800 to the corresponding mixing device.

[0101] The material distribution device also includes a second heating section 860, which is used to heat or keep warm the material conveyed by the conveying section 800. There are no restrictions on the second heating section 860. It can be an electric second heating section 860, such as an electric heating and heat preservation auger, or it can be configured to heat the material by heating a heat exchange medium that flows through the side wall of the conveying section to exchange heat with the material.

[0102] like Figure 1In the illustrated embodiment, there are two conveying units 800, each with two conveying ports. The four conveying ports are designated as a first conveying port 810, a second conveying port 820, a third conveying port 830, and a fourth conveying port 840. Four kneading devices are provided, each corresponding to one of the four conveying ports. When the kneading device corresponding to the first conveying port 810 needs to be fed, the dispensing valve 700 switches to the desired feeding direction, the second heating unit 860 opens, and the valve unit 850 corresponding to the first conveying port 810 opens. When the first material hopper 200 is opened, the valve 850 corresponding to other conveying ports closes, the second valve 220 opens, and the material in the first material hopper 200 can pass through the distribution valve 700, the conveying section 800 and be discharged from the first conveying port 810 into the preheating pot of the corresponding kneading device. When the weighing device 300 detects that the first material hopper 200 has finished discharging, the second valve 220 closes, and after a preset time, the conveying section 800 also stops conveying, the valve 850 corresponding to the first conveying port 810 closes, and the feeding of the kneading device corresponding to the first conveying port 810 ends.

[0103] The carbon production equipment provided in this embodiment uses intelligent control and precise buffering design of the conveying device 100 to preheat materials, realizing raw material preheating, continuous feeding and energy consumption optimization, effectively solving the problems of low efficiency and high energy consumption in traditional processes, and providing technical support for improving the quality and efficiency of carbon workshop production.

[0104] In the carbon production equipment provided in this embodiment, the batching device batches materials and intermittently supplies them to the conveying mechanism. The conveying mechanism continuously transports the materials from the second silo 500 to the second silo 500, and heats the materials during the conveying process. The conveying mechanism intermittently supplies materials to the kneading device according to its feeding requirements. Preheating the materials by the conveying device 100 reduces the residence time of the materials in the preheating pot, thereby effectively improving carbon production efficiency.
