Description

Technical Field

[0001] The present application relates to the technical field of methanol production, and in particular to a production device for producing methanol by hydrogenating biomass synthesis gas. Background Art

[0002] Methanol is an organic compound that can be produced by hydrogenating carbon monoxide. In order to make the methanol production process green and environmentally friendly, the raw gas for preparing methanol is usually extracted from the gasification products of biomass.

[0003] Biomass gasification is usually achieved using a biomass gasifier. The crushed biomass raw materials are added to the biomass gasifier, and the biomass raw materials are oxidized, reduced, cracked and dried in the gasifier to finally obtain a raw gas mainly composed of carbon monoxide and hydrogen.

[0004] When feeding the biomass gasifier, the materials are usually added directly into the furnace body from the hopper. The crushed biomass raw materials are easy to accumulate in the furnace body. The accumulated biomass raw materials are easy to burn through during combustion, which can easily lead to explosion accidents. Summary of the invention

[0005] In order to make the biomass raw materials evenly distributed in the furnace body and not easily burn through, the present application provides a production equipment for hydrogenating biomass synthesis gas to produce methanol.

[0006] The present application provides a production equipment for producing methanol by hydrogenation of biomass synthesis gas, which adopts the following technical solution:

[0007] A production device for producing methanol by hydrogenating biomass synthesis gas, comprising a furnace body and a material distribution component arranged in the furnace body, wherein the material distribution component comprises a material storage part, a sealing part, an unsealing part and a spreading part;

[0008] The material storage part includes a feed pipe, a connecting pipe, a material balancing ball box and a material storage spring;

[0009] The connecting pipe is sleeved on the feed pipe, and the connecting pipe is slidably connected to the feed pipe; the equalizing ball box is connected to the connecting pipe and communicated with the connecting pipe, and a plurality of discharge holes are opened on the equalizing ball box; the storage spring is connected between the feed pipe and the equalizing ball box, and is used to drive the equalizing ball box to slide close to the feed pipe; the feed pipe is used to guide the biomass raw materials into the equalizing ball box, and the sum of the discharge flow of all the discharge holes is equal to the feed flow of the feed pipe;

[0010] More than two sealing parts are arranged around the axis direction of the feed pipe and are all located in the material distribution ball box. The sealing parts include a sealing slide bar, a folding cloth and a sealing spring.

[0011] Two sealing slide bars are provided, and both are arranged in close contact with the inner wall of the ball-balanced material box. The sealing slide bars are slidably connected with the ball-balanced material box around the axis direction of the feed pipe; the folding cloth is provided between the two sealing slide bars, and the folding cloth is used to seal the discharge hole; the sealing spring is provided between the two sealing slide bars, and the sealing spring is used to drive the two sealing slide bars with two adjacent sealing parts close to each other to abut against each other; all the discharge holes are located in the projection area of ​​the folding cloth in the ball-balanced material box;

[0012] The unsealing part and the scattering part are both arranged between the feed pipe and the connecting pipe. There are more than two unsealing parts, and they correspond to the sealing parts one by one. The unsealing part is used to drive the two sealing slide bars to slide in the direction of approaching each other to release the folding cloth from closing the discharge hole. The scattering part is used to drive the equalizing ball box to rotate when the equalizing ball box is full of biomass raw materials, and the scattering part is used to drive the unsealing part to move when driving the equalizing ball box to rotate.

[0013] By adopting the above technical scheme, under the action of the sealing spring, the folded cloth seals the discharge hole, so that the biomass raw materials can be accumulated in the uniform material ball box; under the elastic force of the storage spring, the feed pipe and the connecting pipe remain stationary, and as the biomass raw materials accumulate, the feed pipe and the connecting pipe slide relative to each other, and the state of the uniform material ball box being full of biomass raw materials can be identified through the sliding stroke of the feed pipe and the connecting pipe; when the uniform material ball box is full of biomass raw materials, the scattering part drives the uniform material ball box to rotate and drives the unsealing part to move, and the unsealing part drives the two sealing slide bars to slide in a direction close to each other, so as to release the folded cloth from the sealing of the discharge hole, so that the biomass raw materials can be evenly scattered from the discharge hole into the furnace body, so that the biomass raw materials can be evenly distributed in the furnace body without being easily burned through.

[0014] Optionally, the unsealing part includes an unsealing shaft, an unsealing wheel, an unsealing rope and an unsealing ring, with a spacing between the inner wall of the connecting tube and the outer wall of the feeding tube, a connecting block is connected to the inner wall of the connecting tube, and the unsealing shaft is rotatably passed through the connecting block; the unsealing wheel is connected to the end of the unsealing shaft away from the material equalizing ball box; the unsealing rope is passed through the end of the unsealing shaft close to the material equalizing ball box, and the two ends of the unsealing rope are respectively connected to two sealing slide rods; the unsealing ring is sleeved on the feeding tube; when the material equalizing ball box is full of biomass raw materials, the unsealing wheel is opposite to the unsealing ring, and the side wall of the unsealing wheel abuts against the unsealing ring.

[0015] By adopting the above technical scheme, the biomass raw materials are gradually accumulated in the equalizing ball box to drive the connecting pipe to slide relative to the feeding pipe until the biomass raw materials fill the equalizing ball box. At this time, the connecting pipe drives the unsealing wheel to move to the unsealing ring, so that the unsealing wheel and the unsealing ring are in abutment state, and the equalizing ball box is rotated. The equalizing ball box drives the unsealing wheel to roll on the unsealing ring. When the unsealing wheel rotates, the unsealing rope can be wound around the unsealing shaft. The unsealing rope pulls the two sealing slide bars to slide in a direction close to each other, and at the same time makes the folding cloth folded and stored, thereby opening the discharge hole, so that the biomass raw materials in the equalizing ball box can be scattered from the discharge hole into the furnace body after being filled.

[0016] Optionally, a slip ring is connected to the inner wall of the connecting pipe, and the inner diameter of the slip ring is smaller than the outer diameter of the unsealing ring.

[0017] By adopting the above technical solution, the unsealing ring can limit the downward movement of the slip ring, so that the connecting pipe is not easy to slip off the feed pipe.

[0018] Optionally, the spreading part includes a transmission magnetic ring, a transmission magnetic disk and a motor, the transmission magnetic ring is sleeved on the outer wall of the connecting pipe; the transmission magnetic disk is located on one side of the transmission magnetic ring and is rotatably connected to the side wall of the feed pipe, and the side wall of the transmission magnetic disk is used for magnetic attraction connection with the side wall of the transmission magnetic ring; the motor is installed at the top of the furnace body, and the output shaft of the motor is connected to the transmission magnetic disk; when the material balancing ball box is full of biomass raw materials, the side wall of the transmission magnetic ring is opposite to the side wall of the transmission magnetic disk.

[0019] By adopting the above technical scheme, when the material-distributing ball box is full of biomass raw materials, the transmission magnetic ring slides down to the transmission magnetic disk along with the connecting pipe, and a magnetic drive connection relationship is formed between the transmission magnetic disk and the transmission magnetic ring. The motor drives the transmission magnetic disk to rotate, and the transmission magnetic disk drives the transmission magnetic ring to rotate, and the transmission magnetic ring drives the connecting pipe to rotate, so that the connecting pipe can rotate relative to the feed pipe. On the one hand, the connecting pipe can drive the unsealing wheel to roll on the unsealing ring. On the other hand, after the discharge hole is unsealed, the connecting pipe can drive the material-distributing ball box to rotate, and the material-distributing ball box evenly scatters the accumulated biomass raw materials into the furnace body, so that the biomass raw materials can be evenly distributed in the furnace body without being easily burned through.

[0020] Optionally, when the side wall of the transmission magnetic ring is directly opposite to the side wall of the transmission magnetic disk, a gap is left between the side wall of the transmission magnetic ring and the side wall of the transmission magnetic disk.

[0021] By adopting the above technical scheme, the driving force of the transmission disk on the transmission magnetic ring can be completely derived from the magnetic force. After the unsealing wheel changes from rolling to sliding relative to the unsealing ring, the friction between the unsealing wheel and the unsealing ring can form resistance to the rotation of the transmission magnetic ring. Since the driving force of the transmission disk on the transmission magnetic ring is a non-contact magnetic driving force, the transmission magnetic ring can still be driven by the transmission disk when encountering resistance. Under the joint action of the magnetic driving force and the resistance, the rotation of the equalizing ball box can be in a slow and stable state, so that the biomass raw materials in the equalizing ball box can be stably and evenly scattered into the furnace body.

[0022] Optionally, one end of the storage spring is fixedly connected to the feed pipe, and the other end is fixedly connected to a connecting ring, which is connected to the material distribution ball box so as to rotate around the axial direction of the feed pipe.

[0023] By adopting the above technical solution, the setting of the connecting ring enables the storage spring to rotate relative to the material-balancing ball box, so that the storage spring is not likely to interfere with the rotation of the material-balancing ball box when connecting the feed pipe and the storage spring.

[0024] Optionally, a feeding assembly is provided between the feeding pipe and the top of the furnace body, the feeding assembly comprising a feeding box, a feeding shaft and a feeding plate, the feeding box is in the shape of a circular box with its axis horizontally arranged, the top of the feeding box is connected with a feeding pipe, the feeding pipe is fixedly penetrated on the top of the furnace body, the feeding pipe is used to guide the biomass raw material into the feeding box, and a guide hole is provided at the bottom of the feeding box, and the biomass raw material can flow into the feeding pipe from the guide hole;

[0025] The feeding shaft is coaxially rotatable and arranged in the feeding box. Four feeding plates are provided and are evenly arranged around the axial direction of the feeding shaft. One side of the feeding plate is connected to the feeding shaft, and the other side is used to abut against the inner wall of the feeding box. The projection of the feeding tube at the bottom end of the feeding box coincides with the material guide hole, and the area between two adjacent feeding plates away from one end of the feeding shaft is adapted to the material guide hole.

[0026] By adopting the above technical solution, since the area between two adjacent feeding plates away from one end of the feeding shaft is adapted to the material guide hole, and the projection of the feeding tube at the bottom end of the feeding box coincides with the material guide hole, at the same time, there will always be two facing feeding plates among the four feeding plates abutting against the side wall of the feeding box, so that the feeding plates can always keep the feeding tube and the material guide hole in a closed state; the biomass raw material flows into the feeding tube, and the feeding shaft is rotated to drive the feeding plate to rotate, and the biomass raw material in the feeding tube falls between the two adjacent feeding plates. The feeding plate drives the biomass raw material to flow to the material guide hole during the rotation process, and under the joint action of the four feeding plates, the biomass raw material can be fed in a sealed and continuous manner.

[0027] Optionally, a centering component is arranged between the feeding box and the feeding pipe, and the centering component includes a centering tube and a centering portion. The centering tube is connected between the material guide hole and the feeding pipe. Two centering portions are arranged and are both connected to the side wall of the centering tube. The two centering portions are symmetrically arranged on both sides of the feeding shaft. The two centering portions are used to form an inclined confluence inside the centering tube so that the biomass raw material can flow in the center of the centering tube.

[0028] By adopting the above technical solution, the feeding plate can not only make the biomass raw materials sealed and continuously fed, but also change the feeding direction of the biomass raw materials from central feeding to lateral feeding. The inclined confluence formed by the two centering parts can convert the lateral flow of biomass raw materials into central flow in an inclined converging manner, so that the biomass raw materials are not prone to uneven stacking when flowing into the material equalization component.

[0029] Optionally, the centering part includes two centering plates, which are arranged along the flow direction of the biomass raw material, and the two centering plates are hinged, and the side of the centering plate close to the feeding shaft away from the hinged side is slidably arranged on the side wall of the centering pipe, and the side of the centering plate close to the feeding pipe away from the hinged side is hinged on the side wall of the centering pipe;

[0030] The centering assembly also includes a vibration part, which includes a centering spring, a vibration slide rod, a push rod and a vibration rod. Two centering springs are provided and are respectively arranged between two centering plates of each centering part. The centering spring is used to drive the opening angle between the two centering plates to increase.

[0031] The two ends of the vibrating slide bar are respectively slidably set on the side walls of the two centering tubes where the two centering parts are located along the flow direction of the biomass raw materials. The vibrating slide bar is connected to a push rod, and the push rod is connected to a vibrating rod. The two ends of the vibrating rod are respectively abutted against the two centering plates of the two centering parts close to the feeding shaft. When the feeding plate slides over the vibrating slide bar, the vibrating slide bar drives the vibrating rod to reduce the opening angle of the two hinged centering plates.

[0032] By adopting the above technical solution, when the feeding plate rotates to the material guide hole, it can push the vibration slide bar to slide down, and the vibration slide bar drives the push rod and the vibration rod to slide down, and the vibration rod drives the centering plate to swing, so that the inclined confluence port can be reduced; after the feeding plate slides through the material guide hole, the centering spring can drive the centering plate to swing in the opposite direction for reset, so that the inclined confluence port can be expanded, so that when the feeding plate transports biomass raw materials, the inclined confluence port can be cyclically reduced and expanded, thereby preventing the biomass raw materials from being easily blocked at the inclined confluence port.

[0033] Optionally, the output shaft of the motor is located at one end of the feeding shaft, and a bevel gear set is connected to the output shaft of the motor, and the bevel gear set is connected to the feeding shaft.

[0034] By adopting the above technical solution, when the motor drives the transmission disk, the motor can synchronously drive the feeding shaft to rotate through the bevel gear set, so that the feeding shaft can use the driving source of the transmission disk, thereby reducing energy consumption.

[0035] In summary, the present application includes at least one of the following beneficial technical effects:

[0036] 1. By setting the material storage part, the sealing part, the unsealing part and the driving and spreading part, the biomass raw materials can be evenly scattered into the furnace body from the discharge hole, so that the biomass raw materials can be evenly distributed in the furnace body and are not prone to burn-through;

DETAILED DESCRIPTION

[0045] The following is combined with Figure 1-4 This application is described in further detail.

[0046] The present application embodiment discloses a production device for producing methanol by hydrogenation of biomass synthesis gas. Figure 1 and Figure 2 A production device for producing methanol by hydrogenating biomass synthesis gas includes a furnace body 1, a material distribution component 2, a feeding component 3 and a centering component 4. The furnace body 1 is vertically arranged, and the feeding component 3, the centering component 4 and the material distribution component 2 are all located in the furnace body 1 and are connected in sequence along the vertical downward direction. The feeding component 3 is used for adding biomass raw materials in a side-sealed manner, the centering component 4 is used for making the biomass raw materials flow to the material distribution component 2 in the center, and the material distribution component 2 is used for evenly spreading the biomass raw materials in the furnace body 1 after material storage.

[0047] When adding biomass raw materials, the feeding component 3 keeps the furnace body 1 in a sealed state, and the air pressure in the furnace body 1 is always in a stable state, so that the raw material gas generated in the furnace body 1 is not easy to leak to the outside of the furnace body 1; since the feeding component 3 adds materials in a side-sealed manner, in order to enable the biomass raw materials to flow into the material-leveling component 2 in the center, so that the biomass raw materials are not easy to pile up at the material-leveling component 2, the centering component 4 adjusts the flow direction of the biomass raw materials from lateral flow to central flow; the material-leveling component 2 first accumulates the biomass raw materials flowing in the center, and then the material-leveling component 2 evenly scatters the accumulated biomass raw materials in the furnace body 1, so that the biomass raw materials can be evenly distributed in the furnace body 1 and are not easy to burn through.

[0048] Specifically, refer to Figure 2 and Figure 3 The feeding assembly 3 includes a feeding box 31, a feeding shaft 32 and a feeding plate 33. The feeding box 31 is in the shape of a circular box with its axis horizontally arranged. The top of the feeding box 31 is connected with a feeding pipe 311, and the feeding pipe 311 is fixedly penetrated on the top of the furnace body 1. The feeding pipe 311 is used to guide the biomass raw materials into the feeding box 31. The bottom end of the feeding box 31 is provided with a guide hole 312. The biomass raw materials in the feeding box 31 can flow into the adjusting assembly 4 from the guide hole 312, and the projection of the feeding pipe 311 at the bottom end of the feeding box 31 coincides with the guide hole 312.

[0049] Reference Figure 3 The feeding shaft 32 is coaxially rotatably arranged in the feeding box 31, four feeding plates 33 are provided, and are evenly arranged around the axial direction of the feeding shaft 32, one side of the feeding plate 33 is fixedly connected to the feeding shaft 32, and the other side is used to abut against the inner wall of the feeding box 31, and the area between two adjacent feeding plates 33 away from one end of the feeding shaft 32 is adapted to the material guide hole 312.

[0050] Since the area between two adjacent feeding plates 33 away from one end of the feeding shaft 32 is adapted to the material guide hole 312, and the projection of the feeding tube 311 at the bottom end of the feeding box 31 coincides with the material guide hole 312, at the same time, there will always be two facing feeding plates 33 among the four feeding plates 33 abutting against the side wall of the feeding box 31, so that the feeding plates 33 can always keep the feeding tube 311 and the material guide hole 312 in a closed state; the biomass raw material flows into the feeding tube 311, and the feeding shaft 32 is rotated to drive the feeding plate 33 to rotate, and the biomass raw material in the feeding tube 311 falls between the two adjacent feeding plates 33. The feeding plate 33 drives the biomass raw material to flow to the material guide hole 312 during the rotation process. Under the joint action of the four feeding plates 33, the biomass raw material can be fed in a sealed and continuous manner.

[0051] Specifically, refer to Figure 3 The centering component 4 includes a centering tube 41 and a centering portion 42. One end of the centering tube 41 is connected to the material guide hole 312. Two centering portions 42 are provided and are both connected to the side walls of the centering tube 41. The two centering portions 42 are symmetrically arranged on both sides of the feeding shaft 32. The two centering portions 42 are used to form an inclined confluence inside the centering tube 41 so that the biomass raw material flows in the center of the centering tube 41.

[0052] The feeding plate 33 not only enables the biomass raw materials to be sealed and continuously fed, but also changes the feeding direction of the biomass raw materials from central feeding to lateral feeding. The inclined confluence formed by the two centering parts 42 can convert the lateral flow of biomass raw materials back to central flow in an inclined converging manner, making it less likely for the biomass raw materials to be unevenly stacked when flowing into the material equalizing component 2.

[0053] Among them, refer to Figure 3 The centering portion 42 includes two centering plates 421, and the two centering plates 421 are arranged along the flow direction of the biomass raw material. The two centering plates 421 are hinged, and the centering plate 421 close to the feeding shaft 32 is slidably arranged on the side wall of the centering tube 41 away from the hinged side, and the sliding direction is parallel to the flow direction of the biomass raw material. The two centering plates 421 close to the feeding shaft 32 are tilted in the vertical downward direction along the direction of approaching each other, and the centering plate 421 close to the feeding pipe 211 is hinged on the side wall of the centering tube 41 away from the hinged side. The two centering plates 421 close to the feeding pipe 211 are tilted in the vertical upward direction along the direction of approaching each other.

[0054] The two centering plates 421 close to the feeding shaft 32 are arranged vertically and tilted downward to form an inclined confluence port for the biomass raw materials, so that the biomass raw materials flowing out from one side of the guide hole 312 can flow in the center after being gathered.

[0055] Further, refer to Figure 3 The centering assembly 4 further includes a vibrating portion 43, the vibrating portion 43 includes a centering spring 431, a vibrating slide bar 432, a push rod 433 and a vibrating rod 434, two centering springs 431 are provided, and are respectively fixed between two centering plates 421 of each centering portion 42, and the centering spring 431 is used to drive the opening angle between the two centering plates 421 to increase;

[0056] The two ends of the vibration slide bar 432 are respectively slidably arranged on the side walls of the centering tube 41 where the two centering parts 42 are located along the flow direction of the biomass raw materials. The vibration slide bar 432 is fixedly connected with a push rod 433, and the push rod 433 is fixedly connected with a vibration rod 434. The two ends of the vibration rod 434 are respectively abutted against the two centering plates 421 of the two centering parts 42 close to the feeding shaft 32. When the feeding plate 33 slides over the vibration slide bar 432, the vibration slide bar 432 drives the vibration rod 434 to reduce the opening angle of the two hinged centering plates 421.

[0057] When the feeding plate 33 rotates to the material guide hole 312, it can push the vibration slide bar 432 to slide down, and the vibration slide bar 432 drives the push rod 433 and the vibration rod 434 to slide down, and the vibration rod 434 drives the centering plate 421 to swing to shrink the inclined confluence; after the feeding plate 33 slides through the material guide hole 312, the centering spring 431 can drive the centering plate 421 to swing in the opposite direction to reset, so that the inclined confluence can be expanded, so that when the feeding plate 33 transports biomass raw materials, the inclined confluence can be cyclically shrunk and expanded, thereby preventing the biomass raw materials from being easily blocked at the inclined confluence.

[0058] Specifically, refer to Figure 2 and Figure 3 The material distribution component 2 includes a storage part 21, a sealing part 22, an unsealing part 23 and a scattering part 24. The storage part 21 is used to accumulate the biomass raw materials transported by the regulating pipe 41, and the storage part 21 is used to scatter the accumulated biomass raw materials into the furnace body 1. The sealing part 22 is used to block the storage part 21 from scattering the biomass raw materials, so that the storage part 21 can accumulate the biomass raw materials. The unsealing part 23 is used to remove the obstruction of the sealing part 22 to the scattering of the storage part 21, so that the storage part 21 can scatter the accumulated biomass raw materials. The scattering part 24 is used to drive the unsealing part 23 to operate when the storage part 21 accumulates the biomass raw materials to a preset weight, so that the unsealing part 23 can remove the obstruction of the sealing part 22 to the scattering of the storage part 21, and the scattering part 24 is used to drive the storage part 21 to evenly scatter the biomass raw materials after driving the unsealing part 23 to operate.

[0059] Therefore, under the action of the sealing part 22, the biomass raw materials can be accumulated in the storage part 21 first. When the biomass raw materials accumulate to a preset weight, the scattering part 24 drives the unsealing part 23 to operate, so that the unsealing part 23 releases the obstruction of the sealing part 22 to the scattering of the storage part 21, and then the scattering part 24 drives the storage part 21 to evenly scatter the biomass raw materials, so that the biomass raw materials can be evenly distributed in the furnace body 1 without the occurrence of burn-through.

[0060] More specifically, see Figure 3 The material storage part 21 includes a feeding pipe 211 , a connecting pipe 212 , a material distribution ball box 213 and a material storage spring 214 .

[0061] Reference Figure 2 and Figure 3 One end of the feed pipe 211 is flared and connected to the end of the regulating pipe 41 away from the charging box 31. The connecting pipe 212 is sleeved on the feed pipe 211, and the connecting pipe 212 is slidably connected to the feed pipe 211 in the vertical direction. The equalizing ball box 213 is fixedly connected to the connecting pipe 212 and is connected to the connecting pipe 212. A plurality of discharge holes 2131 are provided on the equalizing ball box 213. The discharge holes 2131 are used to scatter biomass raw materials, and the sum of the discharge flow rates of all the discharge holes 2131 is equal to the feed flow rate of the feed pipe 211. The storage spring 214 is connected between the feed pipe 211 and the equalizing ball box 213, and is used to drive the equalizing ball box 213 to slide close to the feed pipe 211. The feed pipe 211 is used to guide the biomass raw materials in the regulating pipe 41 into the equalizing ball box 213.

[0062] The biomass raw materials can flow from the feed pipe 211 through the connecting pipe 212 into the equalizing ball box 213. Under the action of the sealing portion 22, the biomass raw materials can accumulate in the equalizing ball box 213 to increase the weight of the equalizing ball box 213. The equalizing ball box 213 pulls the connecting pipe 212 down under the action of gravity, and makes the storage spring 214 accumulate elastic force to adjust the position of the connecting pipe 212 relative to the feed pipe 211.

[0063] More specifically, see Figure 3 Four sealing parts 22 are evenly arranged around the axial direction of the feed pipe 211 and are all located in the ball-averaging box 213 . The sealing parts 22 include a sealing slide bar 221 , a folded cloth 222 and a sealing spring 223 .

[0064] There are two sealing slide bars 221, and both are arranged in close contact with the inner wall of the ball-distributing box 213. The sealing slide bars 221 are slidably connected to the ball-distributing box 213 around the axial direction of the feed tube 211; the folding cloth 222 is fixed between the two sealing slide bars 221, and the folding cloth 222 is used to close the discharge hole 2131; the sealing spring 223 is fixed between the two sealing slide bars 221, and is arranged close to the bottom of the ball-distributing box 213, and the sealing spring 223 is used to drive the two sealing slide bars 221 of two adjacent sealing parts 22 to abut against each other.

[0065] Reference Figure 2 and Figure 3 All the discharge holes 2131 are located within the projection area of ​​the folding cloth 222 on the material distribution ball box 213, so that the folding cloth 222 can close all the discharge holes 2131, making it less likely for the material distribution ball box 213 to leak during the material storage process.

[0066] Among them, refer to Figure 3 Two sliders 2211 are fixedly connected to one side of the sealing slide bar 221 close to the inner wall of the ball-distributing box 213. The two sliders 2211 are respectively arranged close to the two ends of the sealing slide bar 221. The sliders 2211 are slidably arranged in the slide grooves 2132 opened on the inner wall of the ball-distributing box 213. The sliders 2211 and the slide grooves 2132 form a sliding connection structure between the sealing slide bar 221 and the ball-distributing box 213, so that the sealing slide bar 221 can slide against the ball-distributing box 213.

[0067] Under the elastic force of the sealing spring 223, the two sealing slide bars 221 of each sealing part 22 slide in the direction away from each other, and the two sealing slide bars 221 of two adjacent sealing parts 22 that are close to each other can be in abutment state, and the sealing slide bar 221 drives the folding cloth 222 to open, and the folding cloth 222 can close the discharge hole 2131, so that the biomass raw materials in the equalizing ball box 213 can be accumulated.

[0068] In particular, refer to Figure 3 A spacing is left between the inner wall of the connecting tube 212 and the outer wall of the feeding tube 211, so that the connecting tube 212 and the feeding tube 211 can not only slide relative to each other but also rotate relative to each other around the axial direction of the feeding tube 211, and the spacing between the connecting tube 212 and the feeding tube 211 is also convenient for installing the unsealing part 23.

[0069] More specifically, see Figure 3 and Figure 4There are four unsealing parts 23, which correspond to the sealing hole parts 22 one by one. The unsealing parts 23 include an unsealing shaft 231, an unsealing wheel 232, an unsealing rope 233 and an unsealing ring 234. A connecting block 2122 is connected to the inner wall of the connecting tube 212. The unsealing shaft 231 is rotatably penetrated on the connecting block 2122; the unsealing wheel 232 is fixedly connected to the end of the unsealing shaft 231 away from the ball box 213; the unsealing rope 23 ... It is passed through one end of the unsealing shaft 231 close to the material-distributing ball box 213, and the two ends of the unsealing rope 233 are respectively fixedly connected to the two sealing hole slide rods 221; the unsealing ring 234 is fixedly sleeved on the feeding pipe 211; when the material-distributing ball box 213 is full of biomass raw materials, that is, the accumulation of biomass raw materials reaches a preset weight, the unsealing wheel 232 is opposite to the unsealing ring 234, and the side wall of the unsealing wheel 232 abuts against the unsealing ring 234.

[0070] The biomass raw materials gradually accumulate in the equalizing ball box 213 to drive the connecting pipe 212 to slide relative to the feeding pipe 211 until the biomass raw materials fill the equalizing ball box 213. At this time, the connecting pipe 212 drives the unsealing wheel 232 to move to the unsealing ring 234, so that the unsealing wheel 232 and the unsealing ring 234 are in abutment state, and the equalizing ball box 213 is rotated. The equalizing ball box 213 drives the unsealing wheel 232 to roll on the unsealing ring 234. When the unsealing wheel 232 rotates, the unsealing rope 233 can be wound around the unsealing shaft 231. The unsealing rope 233 pulls the two sealing slide bars 221 to slide in a direction close to each other, and at the same time makes the folding cloth 222 folded and stored, thereby opening the discharge hole 2131, so that the biomass raw materials in the equalizing ball box 213 can be scattered from the discharge hole 2131 into the furnace body 1 after being filled.

[0071] Among them, refer to Figure 4 A slip ring 2121 is fixedly connected to the inner wall of the connecting tube 212, and the inner wall of the slip ring 2121 is attached to the outer wall of the feeding tube 211. The slip ring 2121 is connected to the cylindrical sleeve pair of the feeding tube 211, so that the connecting tube 212 and the feeding tube 211 can easily achieve relative sliding and relative rotation. At the same time, since the unsealing ring 234 is located on the outer wall of the feeding tube 211, the inner diameter of the slip ring 2121 is smaller than the outer diameter of the unsealing ring 234. The unsealing ring 234 can limit the downward movement of the slip ring 2121, so that the connecting tube 212 is not easy to slip off the feeding tube 211.

[0072] Among them, refer to Figure 4Four storage springs 214 are evenly arranged around the axial direction of the feed pipe 211. One ends of the four storage springs 214 are fixedly connected to the feed pipe 211, and the other ends are commonly fixedly connected to a connecting ring 2141. The connecting ring 2141 is embedded in the outer wall of the equalizing ball box 213 and is rotatable around the axial direction of the feed pipe 211 and connected to the equalizing ball box 213. The setting of the connecting ring 2141 allows the storage springs 214 to rotate relative to the equalizing ball box 213, so that the storage springs 214 are not likely to interfere with the rotation of the equalizing ball box 213 when connecting the feed pipe 211 and the storage springs 214.

[0073] Among them, refer to Figure 4 A receiving groove 2212 for receiving the folding cloth 222 is provided on one side of the sealing slide bar 221 close to the folding cloth 222. When the sealing slide bar 221 drives the folding cloth 222 to fold to open the discharge hole 2131, the folding cloth 222 can be stacked in the receiving groove 2212, so that the folded state of the folding cloth 222 is not easy to interfere with the sliding of the sealing slide bar 221.

[0074] More specifically, see Figure 2 The driving and spreading part 24 includes a transmission magnetic ring 241, a transmission disk 242 and a motor 243. The transmission magnetic ring 241 is fixedly sleeved on the outer wall of the connecting pipe 212; the transmission disk 242 is located on one side of the transmission magnetic ring 241 and is fixedly connected with a connecting shaft 2421. The connecting shaft 2421 is rotatably connected to the side wall of the feed pipe 211. The connecting shaft 2421 forms a rotational connection relationship between the transmission disk 242 and the side wall of the feed pipe 211. The side wall of the transmission disk 242 is used for magnetic connection with the side wall of the transmission magnetic ring 241; the motor 243 is fixedly arranged at the top of the furnace body 1, and the output shaft of the motor 243 rotates and penetrates into the furnace body 1. The output shaft of the motor 243 is fixedly connected to the connecting shaft 2421. The connecting shaft 2421 forms a driving connection relationship between the output shaft of the motor 243 and the transmission disk 242; when the balancing ball box 213 is full of biomass raw materials, the side wall of the transmission magnetic ring 241 is directly opposite to the side wall of the transmission disk 242.

[0075] When the material-distributing ball box 213 is full of biomass raw materials, the transmission magnetic ring 241 slides down to the transmission disk 242 along with the connecting pipe 212, and a magnetic drive connection relationship is formed between the transmission disk 242 and the transmission magnetic ring 241. The motor 243 drives the transmission disk 242 to rotate, and the transmission disk 242 drives the transmission magnetic ring 241 to rotate, and the transmission magnetic ring 241 drives the connecting pipe 212 to rotate, so that the connecting pipe 212 can rotate relative to the feed pipe 211. On the one hand, the connecting pipe 212 can drive the unsealing wheel 232 to roll on the unsealing ring 234. On the other hand, after the discharge hole 2131 is unsealed, the connecting pipe 212 can drive the material-distributing ball box 213 to rotate, and the material-distributing ball box 213 evenly scatters the accumulated biomass raw materials into the furnace body 1, so that the biomass raw materials can be evenly distributed in the furnace body 1 without being easily burned through.

[0076] Further, refer to Figure 4 When the side wall of the transmission magnetic ring 241 is directly opposite to the side wall of the transmission disk 242, a gap is left between the side wall of the transmission magnetic ring 241 and the side wall of the transmission disk 242, so that the driving force of the transmission disk 242 on the transmission magnetic ring 241 can be completely derived from the magnetic force. After the unsealing wheel 232 changes from rolling to sliding relative to the unsealing ring 234, the friction between the unsealing wheel 232 and the unsealing ring 234 can form resistance to the rotation of the transmission magnetic ring 241. Since the driving force of the transmission disk 242 on the transmission magnetic ring 241 is a non-contact magnetic driving force, the transmission magnetic ring 241 can still be driven by the transmission disk 242 under the condition of resistance. Under the joint action of the magnetic driving force and the resistance, the rotation of the equalizing ball box 213 can be in a slow and stable state, so that the biomass raw materials in the equalizing ball box 213 can be stably and evenly scattered into the furnace body 1.

[0077] Furthermore, refer to Figure 2 and Figure 3 The output shaft of the motor 243 is located at one end of the feeding shaft 32, and a bevel gear set 2431 is connected to the output shaft of the motor 243. The bevel gear set 2431 is connected to the feeding shaft 32. The bevel gear set 2431 is used to transmit the driving force of the output shaft of the motor 243 to the feeding shaft 32. When the motor 243 drives the transmission disk 242, the motor 243 can synchronously drive the feeding shaft 32 to rotate through the bevel gear set 2431, so that the feeding shaft 32 can use the driving source of the transmission disk 242, thereby reducing energy consumption.

[0078] The implementation principle of the production equipment for hydrogenating biomass synthesis gas to methanol in the embodiment of the present application is as follows: when in use, the biomass raw material is added into the feeding box 31 from the feeding pipe 311, the motor 243 drives the feeding plate 33 to rotate, the feeding plate 33 seals and continuously drives the biomass raw material to flow into the centering pipe 41, and under the action of the symmetrically arranged centering plate 421, the biomass raw material flows into the feeding pipe 211 in the center, and the biomass raw material flows from the feeding pipe 211 into the equalizing ball box 21 3, under the sealing effect of the folded cloth 222, the biomass raw materials are accumulated in the evenly distributed ball box 213 until the transmission magnetic ring 241 is directly opposite to the transmission magnetic disk 242, and the motor 243 drives the connecting pipe 212 and the evenly distributed ball box 213 to rotate, and the connecting pipe 212 drives the unsealing rope 233 to be wound around the unsealing shaft 231 to release the sealing of the folded cloth 222 on the discharge hole 2131, and the evenly distributed ball box 213 evenly scatters the accumulated biomass raw materials into the furnace body 1 during the rotation process.

[0079] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
