Description

Technical Field

[0001] The present application relates to the technical field of powder degassing devices, and more particularly, to a compression degassing device for compressing and degassing carbon black. Background Art

[0002] In the production process of acetylene carbon black, the high-temperature cracking of acetylene usually yields a mixture of acetylene carbon black and hydrogen. Acetylene carbon black is a nano-porous material with a low density and is prone to adsorbing the hydrogen generated during cracking, making it difficult to separate. However, if the acetylene carbon black is not degassed thoroughly before entering the finished product bin, the hydrogen entering the bin will pose a significant safety hazard. Additionally, to meet the requirements for different fluffiness degrees of acetylene carbon black products, different degrees of compression of acetylene carbon black are needed.

[0003] Therefore, a device capable of compressing and degassing acetylene carbon black is required. Summary of the Utility Model

[0004] The present application provides a compression degassing device to solve the problems of compression and degassing of acetylene carbon black powder.

The bin is provided with a feed inlet and a discharge outlet at both ends along its extending direction, and the bin wall of the bin is provided with air outlet holes; the degassing and extrusion mechanism includes an auger extending into the bin, and the auger includes a screw rod and spiral blades arranged on the outer wall of the screw rod; the extending direction of the screw rod is consistent with the extending direction of the bin, and the outer diameter of the screw rod near the feed inlet end is smaller than that near the discharge outlet end; the discharging mechanism includes a discharge cylinder and an adjusting block; the discharge cylinder is located outside the bin and is connected to the bin, and the through hole inside the discharge cylinder is communicated with the discharge outlet; the adjusting block can be selectively inserted into the discharge cylinder to adjust the gap width between the inner wall of the discharge cylinder and the outer wall of the adjusting block.

[0007] When degassing and compressing powder materials such as acetylene black using the above compression degassing equipment, the material can be conveyed from the feed inlet to the silo, and then the material in the silo can be conveyed to the discharge outlet by means of a screw conveyor, and then discharged by the discharge mechanism. Since in the direction from the feed inlet to the discharge outlet, the outer diameter of the screw at the end close to the discharge outlet is larger than that at the end close to the feed inlet, during the process of conveying the material to the discharge outlet by the screw conveyor, the screw conveyor can gradually compress the material and discharge the gas in the material. Moreover, the silo wall is provided with air vents, and the gas discharged when the screw conveyor compresses the material can be discharged from the air vents outside the silo, realizing the degassing of the material. And, a discharge mechanism is provided at the discharge outlet, and the degassed material can enter the discharge cylinder from the discharge outlet and be discharged from the gap between the inner wall of the discharge cylinder and the outer wall of the adjusting block. When it is necessary to discharge compressed products with different degrees of fluffiness, the gap width between the outer wall of the adjusting block and the inner wall of the discharge cylinder can be adjusted.

[0008] In an alternative embodiment, the inner diameter of the through hole gradually decreases in the direction away from the discharge outlet; the discharge mechanism further includes a moving member, the moving member is connected to the adjusting block, and the moving member can selectively drive the adjusting block to extend into the through hole along the axial direction of the discharge cylinder by a preset depth to adjust the gap width between the inner wall of the discharge cylinder and the outer wall of the adjusting block.

[0009] In the above implementation process, a through hole in a frustum shape is arranged in the discharge cylinder, and the inner diameter of the through hole gradually decreases in the direction away from the discharge outlet. When it is necessary to adjust the discharge gap between the outer wall of the adjusting block and the inner wall of the discharge cylinder, the moving member can be used to drive the adjusting block to move along the axial direction of the discharge cylinder, and the change of the inner diameter at different axial positions of the discharge cylinder is used to realize the adjustment of the discharge gap.

[0010] In an alternative embodiment, the outer diameter of the adjusting block gradually increases in the direction away from the discharge outlet, and the moving member can selectively drive the adjusting block to extend into the through hole along the axial direction of the discharge cylinder by a preset depth to adjust the gap width between the inner wall of the end of the discharge cylinder away from the discharge outlet and the outer wall of the adjusting block.

[0011] In the above implementation process, when it is necessary to reduce the discharge gap, the moving member can be used to drive the adjusting block to move towards the discharge outlet, so that the large end of the adjusting block is opposite to the discharge end of the discharge cylinder away from the discharge outlet; when it is necessary to increase the discharge gap, the moving member can be used to drive the adjusting block to move away from the discharge outlet, so that the small end of the adjusting block is opposite to the discharge end of the discharge cylinder away from the discharge outlet.

[0012] In an alternative embodiment, the outer diameter of the adjusting block gradually decreases in the direction away from the discharge outlet, and the moving member can selectively drive the adjusting block to extend into the through hole along the axial direction of the discharge cylinder by a preset depth to adjust the gap width between the inner wall of the discharge cylinder and the outer wall of the adjusting block.

[0013] In the above implementation process, when it is necessary to reduce the discharge gap, the moving member can be used to drive the adjusting block to move away from the discharge port, so that the adjusting block is opposite to the small end of the discharge cylinder; when it is necessary to increase the discharge gap, the moving member can be used to drive the adjusting block to move towards the discharge port, so that the adjusting block is opposite to the large end of the discharge cylinder.

[0014] In an alternative embodiment, the discharge mechanism is further provided with a discharge funnel, the discharge funnel is connected to the discharge port, and the discharge cylinder and the adjusting block are located in the discharge funnel.

[0015] In the above implementation process, a discharge funnel is provided at the discharge port, and both the discharge cylinder and the adjusting block are located in the discharge funnel. The degassed material enters the discharge cylinder from the discharge port of the silo, and then passes through the discharge gap between the inner wall of the discharge cylinder and the outer wall of the adjusting block. After compression, it is discharged from the discharge funnel.

[0016] In an alternative embodiment, the moving member includes a ball screw and a push rod connected to the ball screw; the ball screw is arranged on the outer wall of the top of the discharge funnel, a strip hole extending along the moving direction of the ball screw is provided at the top of the discharge funnel, and the other end of the push rod passes through the strip hole and is connected to the end of the adjusting block facing away from the discharge port.

[0017] In the above implementation process, by providing a ball screw and a strip hole extending along the moving direction of the ball screw at the top of the discharge funnel, one end of the push rod can be connected to the ball screw, and the other end of the push rod can pass through the strip hole and extend into the discharge funnel to be connected to the adjusting block in the discharge funnel. When it is necessary to adjust the width of the discharge gap between the inner wall of the discharge cylinder and the outer wall of the adjusting block, the ball screw can be used to drive the push rod to move along the extending direction of the strip hole, and then the push rod can be used to push the adjusting block to move.

[0018] In an alternative embodiment, the screw rod includes a first rod section and a second rod section connected to each other. The first rod section is close to the feed port, and the second rod section is close to the discharge port; the outer diameter of the first rod section is set to be equal in diameter, and the outer diameter of the second rod section gradually increases towards the discharge port.

[0019] In the above implementation process, the equal-diameter first rod section is close to the feed port, which can improve the conveying efficiency of the material at the discharge port. The outer diameter of the second rod section gradually increases towards the discharge port, which will cause the compression cross-section of the material inside the silo to decrease in proportion during the conveying process, and the compression force of the auger on the material gradually increases, which can gradually compress the material during the conveying process and improve the degassing efficiency of the material.

[0020] In an alternative embodiment, the spiral blades at the first rod section are arranged at equal intervals, and the spacing of the spiral blades at the second rod section gradually decreases towards the discharge port.

[0021] In the above implementation process, the spiral blades at the first rod section are arranged at equal intervals, which can further improve the conveying efficiency of materials such as carbon black. The intervals of the spiral blades of the second rod section gradually decrease, which can further improve the degassing efficiency of the materials.

[0022] In an alternative embodiment, the spiral blades at the second rod section gradually thicken in the direction towards the discharge port.

[0023] In the above implementation process, since the compression cross-section corresponding to the second rod section in the silo gradually decreases and the compression force gradually increases, gradually thickening the spiral blades at the second rod section in the direction towards the discharge port can improve the strength of the spiral blades.

[0024] In an alternative embodiment, a plurality of air outlet holes are arranged at intervals on the wall of the silo; along the extending direction of the silo, a plurality of degassing boxes are arranged at intervals on the wall of the silo, and the degassing boxes are communicated with the air outlet holes.

[0025] In the above implementation process, a plurality of degassing boxes are arranged at the wall of the silo, and the degassing boxes are communicated with the air outlet holes, which can use the degassing boxes to suck out the gas in the silo and improve the degassing efficiency.

[0036] Acetylene black can be obtained by high-temperature pyrolysis of acetylene. Usually, in the production process of acetylene black, high-temperature pyrolysis of acetylene will obtain a mixed product of acetylene black and hydrogen. Acetylene black is a nano-porous material with a small density and is easy to adsorb the hydrogen generated by pyrolysis, making it difficult to separate. However, if the acetylene black is not degassed cleanly before entering the finished product bin and hydrogen enters the bin, it will pose a great safety hazard. In addition, in order to meet the requirements of different fluffiness of acetylene black products, acetylene black needs to be compressed to different degrees.

[0037] Therefore, the present application provides a compression and degassing device 1, which can achieve the degassing and compression of materials such as acetylene carbon black to a certain extent and realize continuous production. To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0038] Please refer to Figure 1 , the compression and degassing device 1 provided by the exemplary embodiment of the present application includes a silo 10, a degassing and extrusion mechanism 20, and a discharging mechanism 30.

[0039] Among them, please continue to refer to Figure 1 , the two ends of the silo 10 along its extending direction are provided with a feed inlet 11 and a discharge outlet 12, and the wall of the silo 10 is provided with air vents 13.

[0040] Among them, please continue to refer to Figure 1 , the degassing and extrusion mechanism 20 includes an auger 21 extending into the silo 10. The auger 21 includes a screw 211 and a spiral blade 212 arranged on the outer wall of the screw 211. The extending direction of the screw 211 is the same as the extending direction of the silo 10, and the outer diameter of the screw 211 near the feed inlet 11 is smaller than the outer diameter near the discharge outlet 12.

[0041] Among them, please continue to refer to Figure 1 and Figure 2 , the discharging mechanism 30 includes a discharge cylinder 31 and an adjusting block 32. The discharge cylinder 31 is located outside the silo 10 and is connected to the silo 10. The through hole 311 inside the discharge cylinder 31 is communicated with the discharge outlet 12; the adjusting block 32 can be selectively extended into the discharge cylinder 31 to adjust the gap width L1 between the inner wall of the discharge cylinder 31 and the outer wall of the adjusting block 32.

[0042] When using the compression and degassing device 1 provided by the exemplary embodiment of the present application for degassing and compression, materials such as acetylene carbon black can be conveyed from the feed inlet 11 into the silo 10, and then the materials in the silo 10 can be conveyed to the discharge outlet 12 by the auger 21, and then discharged by the discharging mechanism 30.

[0043] Since the outer diameter of the screw 211 near the discharge outlet 12 is larger than the outer diameter near the feed inlet 11 in the direction from the feed inlet 11 to the discharge outlet 12, during the process of conveying materials to the discharge outlet 12 by the auger 21, the auger 21 can gradually compress the materials and discharge the gas in the materials. Moreover, the wall of the silo 10 is provided with air vents 13, and the gas discharged when the auger 21 compresses the materials can be discharged from the air vents 13 outside the silo 10 to realize the degassing of the materials.

[0044] A discharging mechanism 30 is provided at the discharging port 12. The degassed material can enter the discharging cylinder 31 from the discharging port 12 and be discharged from the gap between the inner wall of the discharging cylinder 31 and the outer wall of the adjusting block 32. When compressing products with different degrees of fluffiness need to be discharged, the width L1 of the gap between the outer wall of the adjusting block 32 and the inner wall of the discharging cylinder 31 can be adjusted as needed.

[0045] The following further describes in detail the material bin 10, the degassing and extrusion mechanism 20, and the discharging mechanism 30 in the compression degassing device 1 provided by the embodiments of the present application with reference to the accompanying drawings.

[0046] The material bin 10 is used to cooperate with the degassing and extrusion mechanism 20 to degas powder materials such as acetylene carbon black. The extending direction of the material bin 10 is the same as the extending direction of the screw 211 in the auger 21.

[0047] Exemplarily, the material bin 10 is of a cylindrical structure, and the chamber inside the cylinder is cylindrical.

[0048] Exemplarily, the feeding port 11 is arranged at the top of one end of the material bin 10 in the extending direction, and the material can be conveyed downward from the feeding port 11 into the material bin 10.

[0049] Exemplarily, the discharging port 12 is arranged at the end of the other end of the material bin 10 in the extending direction, so that the auger 21 can send the degassed material from the discharging port 12 to the discharging cylinder 31 and be discharged by the discharging cylinder 31.

[0050] Further, in order to facilitate the auger 21 to pass through the material bin 10, in some possible embodiments, a connection hole can be provided at the end of the material bin 10 close to the feeding port 11, and the auger 21 can be passed through the connection hole into the material bin 10.

[0051] The screw 211 of the auger 21 can rotate relative to the connection hole, and the screw 211 is hermetically connected to the connection hole.

[0053] In order to facilitate the gas extruded from the powder material to be discharged out of the material bin 10, air holes 13 communicating with the internal chamber are also provided on the wall of the material bin 10.

[0054] Exemplarily, a plurality of air holes 13 can be arranged at intervals along the extending direction of the material bin 10.

[0055] Further, in order to improve the gas discharge efficiency, in some possible embodiments, a plurality of degassing boxes 14 can be arranged on the wall of the material bin 10, and the degassing boxes 14 are communicated with the air holes 13.

[0056] Exemplarily, an adsorption pump may be provided in the degassing box 14 to suck the gas extruded from the silo 10 into the degassing box 14 through the air outlet 13, and then discharge it through the pipeline at the degassing box 14.

[0057] Exemplarily, one degassing box 14 is simultaneously communicated with a plurality of air outlets 13 to improve the degassing efficiency.

[0058] The degassing and extrusion mechanism 20 includes an auger 21, and the auger 21 extends into the silo 10. The auger 21 includes a screw rod 211 and a spiral blade 212 provided on the screw rod 211. The outer diameter of the screw rod 211 near one end of the feed inlet 11 is smaller than the outer diameter near one end of the discharge outlet 12, and it can gradually compress the material during the conveying process towards the discharge outlet 12 to achieve degassing of the material.

[0059] Further, in order to facilitate improving the conveying efficiency and degassing efficiency of the auger 21, in some possible embodiments, the screw rod 211 of the auger 21 may be set as a first rod section 2111 and a second rod section 2112 connected to each other, and the first rod section 2111 is near the feed inlet 11, and the second rod section 2112 is near the discharge outlet 12. The outer diameter of the first rod section 2111 is set to be equal in diameter, and the outer diameter of the second rod section 2112 gradually increases towards the direction near the discharge outlet 12.

[0060] Exemplarily, the first rod section 2111 and the second rod section 2112 are integrally provided.

[0061] Exemplarily, the length ratio of the first rod section 2111 to the second rod section 2112 is 1:1.5 - 3. For example, the length ratio of the first rod section 2111 to the second rod section 2112 is 1:2.

[0062] Further, in some possible embodiments, the spiral blades 212 at the first rod section 2111 are arranged at equal intervals, and the spacing of the spiral blades 212 at the second rod section 2112 gradually decreases towards the direction near the discharge outlet 12.

[0063] Further, in some possible embodiments, the spiral blades 212 at the second rod section 2112 gradually thicken towards the direction near the discharge outlet 12 to improve the strength of the auger 21.

[0064] Further, in order to facilitate driving the auger 21 to rotate, in some possible embodiments, the degassing and extrusion mechanism 20 may further be provided with a driving member 22.

[0065] Exemplarily, the driving member 22 is a motor.

[0066] Exemplarily, the motor is connected to the end of the screw rod 211 extending outside the silo 10 through a coupling 23.

[0067] Further, the degassing and extrusion mechanism 20 may also be provided with a speed reducer 24. The motor is connected to the speed reducer 24, and the speed reducer 24 is connected to the coupling 23.

[0068] Further, in some possible embodiments, the compression and degassing device 1 may also be provided with a machine platform, and both the material bin 10 and the motor are arranged on the machine platform.

[0069] The discharging mechanism 30 is arranged outside the material bin 10 and communicated with the discharging port 12 of the material bin 10 to compress and discharge the material discharged from the discharging port 12.

[0070] To meet the requirements of different compression and fluffiness degrees, the discharging mechanism 30 is provided with a discharging cylinder 31 and an adjusting block 32. The discharging cylinder 31 is arranged outside the material bin 10 and communicated with the discharging port 12. The adjusting block 32 can extend into the discharging cylinder 31. Therefore, the material flowing into the discharging cylinder 31 from the discharging port 12 will be discharged from the gap between the inner wall of the discharging cylinder 31 and the outer wall of the adjusting block 32.

[0071] Since the adjusting block 32 can selectively extend into the discharging cylinder 31 to adjust the width L1 of the gap between the inner wall of the discharging cylinder 31 and the outer wall of the adjusting block 32, the discharging mechanism 30 provided by the example of the present application can adjust the extrusion degree of the material, thereby adjusting the fluffiness degree of the material.

[0072] To facilitate the adjusting block 32 to adjust the gap width L1 of the discharging, in some possible embodiments, the inner diameter of the through hole 311 of the discharging cylinder 31 gradually decreases in the direction away from the discharging port 12, and the gap width L1 of the discharging can be adjusted by adjusting the depth of the adjusting block 32 extending into the discharging cylinder 31.

[0073] Further, in some possible embodiments, the adjusting block 32 can be set in a frustum shape. The frustum-shaped adjusting block 32 can selectively extend into the discharging cylinder 31 by a certain depth to adjust the gap width L1 of the discharging.

[0074] Exemplarily, please refer to Figure 2 , the adjusting block 32 can be in a frustum shape. The outer diameter of the adjusting block 32 gradually decreases in the direction close to the discharging port 12. The adjusting block 32 extends into the discharging cylinder 31 and can selectively move along the axial direction of the discharging cylinder 31 to adjust the gap width L1 of the discharging. When it is necessary to increase the fluffiness degree of the material after discharging, the adjusting block 32 can be moved along the axial direction of the discharging cylinder 31 in the direction away from the discharging port 12, so that the gap width L1 between the inner wall of the end of the discharging cylinder 31 away from the discharging port 12 and the outer wall of the adjusting block 32 increases. When it is necessary to reduce the fluffiness degree of the material after discharging, the adjusting block 32 can be moved along the axial direction of the discharging cylinder 31 in the direction close to the discharging port 12, so that the gap width L1 between the inner wall of the end of the discharging cylinder 31 away from the discharging port 12 and the outer wall of the adjusting block 32 decreases.

[0075] Exemplarily, the adjusting block 32 can be frustum-shaped, and the outer diameter of the adjusting block 32 gradually increases in the direction close to the discharge port 12 (not shown in the figure). The adjusting block 32 extends into the discharge cylinder 31 and can be selectively moved along the axial direction of the discharge cylinder 31 to adjust the clearance width L1 of the discharge. When it is necessary to increase the fluffiness of the material after discharge, the adjusting block 32 can be moved along the axial direction of the discharge cylinder 31 towards the discharge port 12, so that the clearance width L1 between the inner wall of the discharge cylinder 31 and the outer wall of the end of the adjusting block 32 close to the discharge port 12 increases. When it is necessary to reduce the fluffiness of the material after discharge, the adjusting block 32 can be moved along the axial direction of the discharge cylinder 31 away from the discharge port 12, so that the clearance width L1 between the inner wall of the discharge cylinder 31 and the outer wall of the end of the adjusting block 32 close to the discharge port 12 decreases.

[0076] The present application does not limit the specific shape of the adjusting block 32, and relevant personnel can make corresponding selections under the condition that the adjusting block 32 can cooperate with the frustum-shaped through hole 311 to adjust the clearance width L1.

[0077] Further, in order to facilitate the movement of the adjusting block 32, in some possible embodiments, the discharging mechanism 30 further includes a moving member 33. The moving member 33 is connected to the adjusting block 32, and the moving member 33 can selectively drive the adjusting block 32 to move along the axial direction of the discharge cylinder 31.

[0078] Exemplarily, referring to Figure 2 and Figure 3 , the moving member 33 includes a ball screw 331 and a push rod 332 connected to the ball screw 331. The ball screw 331 drives the push rod 332 to move along the axial direction of the discharge cylinder 31, and then the push rod 332 pushes the adjusting block 32 to move along the axial direction of the discharge cylinder 31.

[0079] Further, a through hole can be provided in the middle of the adjusting block 32, and the end of the auger 21 away from the feed port 11 passes through the discharge port 12 and the through hole of the adjusting block 32.

[0080] Further, the discharging mechanism 30 is further provided with a discharge funnel 34. The discharge funnel 34 is connected to the end of the silo 10 corresponding to the discharge port 12, and both the discharge cylinder 31 and the adjusting block 32 are located in the discharge funnel 34.

[0081] Further, the ball screw 331 can be arranged on the outer wall of the top of the discharge funnel 34. A strip-shaped hole extending in the moving direction of the ball screw 331 is provided at the top of the discharge funnel 34, and the end of the push rod 332 away from the ball screw 331 passes through the strip-shaped hole and is connected to the end of the adjusting block 32 facing away from the discharge port 12.

[0082] Further, in order to facilitate the connection of the discharge cylinder 31 and the discharge funnel 34 to the outer wall of the silo 10 corresponding to the discharge port 12, in some possible embodiments, please refer to Figure 1 and Figure 3 , a first connecting ring 15 can be provided at the outer wall of the silo 10 corresponding to the discharge port 12, a second connecting ring 35 can be provided at the end of the discharge cylinder 31 facing the discharge port 12, and a third connecting ring 36 can be provided at the end of the discharge funnel 34 facing the discharge port 12; the second connecting ring 35 and the third connecting ring 36 are detachably and sealingly connected to the first connecting ring 15 through a connecting member, and the second connecting ring 35 is located inside the third connecting ring 36.
