Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of carbon molecular sieve production, and relates to a carbon molecular sieve production system and method. BACKGROUND

[0002] Carbon molecular sieve is a new type of adsorbent developed in the 1970s, which is a kind of excellent non-polar carbon material. Carbon molecular sieve for nitrogen production (CMS) is used for separating oxygen and nitrogen in air, and finally the separated nitrogen is applied to the industries of corrosion prevention, explosion prevention and combustion prevention, such as aerospace, medicine, electronics, coal mine, cruise ship, oil field and food processing.

[0003] The carbon molecular sieve for nitrogen production originally adopts a normal temperature and low pressure nitrogen production process. The raw material in the original production process is mainly coal, which is a non-renewable material. Not only the non-renewable resources are consumed, but also the atmosphere environment is not friendly in the production process.

[0004] In addition, due to the limitation of the inherent characteristics of raw materials such as coal, there is a technical difficulty in controlling the pore size. Therefore, the pore size of most of the carbon molecular sieve for nitrogen production is distributed in 0.3-1nm, that is, the quality of the carbon molecular sieve for nitrogen production is medium and low grade.

[0005] The normal temperature and low pressure nitrogen production process provided by the prior art adopts a ball mill to coarsely grind the raw material, and a ball mill to finely grind the raw material after coarse grinding and drying. The motor power of the ball mill is large. It is understood that the motor of the coarse grinding process is at least 37KW, and the motor of the fine grinding process is generally not less than 55KW. Moreover, the ball grinding time is generally 35-40 hours, so there is a problem of large power consumption. Moreover, the noise pollution generated by the large power motor and the steel balls used for grinding in the ball mill during work is very serious, and the noise basically reaches 120 decibels.

[0006] The finely ground material is in nanometer level. When the material is sucked into the bin by vacuum, the vacuum material suction machine often does not stop when the material suction is finished. At this time, the idling causes the machine to heat. Or when production is stopped for a period of time and then started again, static electricity is accumulated due to the accumulation of raw materials at the pipe bend. These situations often cause fire, and the fire is difficult to extinguish. SUMMARY

[0007] The purpose of the present application is to provide a carbon molecular sieve production system and method for reducing the energy consumption of carbon molecular sieve production and improving the quality of carbon molecular sieve.

[0040] As a possible implementation manner, the kneading and dividing machine in the first aspect of the kneading powder machine, the crushing method of the kneading powder machine comprises:

[0041] S20. The motor is started to drive the first hollow rotating part in the coarse crushing assembly and the second hollow rotating part in the fine crushing assembly to relatively rotate through the transmission assembly, and the air blowing to the discharge port is generated in the relatively rotating process

[0042] S21. The flower mud base or coarse crushed material is transported to the crushing box through the feeding port, and the rotating first hollow rotating part makes the flower mud base or coarse crushed material reciprocate and impact at each position of the inner wall of the hollow rotating part to crush the flower mud base or coarse crushed material with a large size;

[0044] S23. The relatively rotating first hollow rotating part drives the crushed and kneaded crushed material into the fine crushing assembly to form an 8-shaped kneading path, and finally, the flower mud base or coarse crushed material is kneaded by the coarse crushing assembly and the fine crushing assembly to a corresponding particle size and is blown out of the discharge port by the air.

[0046] As a possible implementation manner, the fine powder meeting the second preset granularity is transported to the fine crushing bin by the following method:

[0047] The fine powder meeting the second preset granularity is transported to the fine crushing bin by a vacuum suction machine; each bend of the pipeline included in the vacuum suction machine is grounded; a temperature detector and a temperature alarm are arranged on the vacuum pump included in the vacuum suction machine, and when the working temperature of the vacuum pump detected by the temperature detector exceeds a preset temperature, the temperature alarm is triggered to alarm; the vacuum suction machine is further configured with a protective gas supply device, and the protective gas is absorbed at the same time when the fine powder is absorbed by the vacuum suction machine.

[0048] As a possible implementation manner, S12 specifically includes the following steps:

[0049] S120. The inner container of the drying machine is taken out, and the tare weight of the inner container is weighed by an electronic overhead scale arranged above the drying machine;

[0050] S121. The inner container is placed on a weight machine, and it is ensured that the inner container is located below the coarse crushing bin;

[0051] S121. The discharge valve of the coarse crushing bin is opened to transport the coarse crushing material to the inner container, and at the same time, the weight of the coarse crushing material added to the inner container is acquired in real time by the weight machine, and when the measured weight of the coarse crushing material is equal to the preset weight, the discharge valve is closed;

[0052] S122. The inner container containing the coarse crushing material with the preset weight is placed into the drying machine again;

[0053] S123. The preset drying temperature of the drying machine is set to 200-400 DEG C, the preset time is set to 120-180 minutes, and the drying machine is started to roast the coarse crushing material.

[0054] Compared with the prior art, the present application has the following advantages:

[0055] First, the flower mud material or the flower mud leftover is used as the raw material for preparing nitrogen-carbon molecules to replace the coal raw material used in the prior art. The flower mud material or the flower mud leftover contains abundant large pores, medium pores, micropores and other pore structures, especially a large amount of micropores and submicropores required for carbon molecular sieve adsorption (in practical application, the large pores and small pores are often used as the channel for gas transmission, and the micropores and submicropores are used as the pore for containing oxygen. Nitrogen is difficult to enter the micropores and submicropores, and thus is isolated outside the carbon molecular sieve to achieve the separation of oxygen and nitrogen. That is, the flower mud material or the flower mud leftover is equivalent to an abundant "pore bank". Compared with the coal raw material, the self characteristics of the flower mud material or the flower mud leftover make the control of the carbon molecular sieve pore size easy. Therefore, the quality of the carbon molecular sieve prepared by using the flower mud material or the flower mud leftover can be effectively improved. In addition, the flower mud material or the flower mud leftover is a non-renewable material, and there is no problem of overconsumption of limited resources. Moreover, there is no problem of air pollution in the production process.

[0056] Second, the kneading powder machine is used in the rough grinding and fine grinding processes. In practical application, the motor is started to drive the first hollow rotating part in the rough crushing assembly and the second hollow rotating part in the fine crushing assembly to relatively rotate through the transmission assembly. In the process of relative rotation, the wind blowing to the discharge port can be generated. Based on this, the waste material such as the head material and the leftover can be conveyed to the crushing box through the feeding port. The rotating first hollow rotating part can make the waste material reciprocally impact at each position of the inner wall of the hollow rotating part to crush the waste material with a large size. After crushing, the waste material falls through the hollow position of the first hollow rotating part into the gap between the first threaded rod. At this time, the friction between the rotating first hollow rotating part and the crushed material and the first threaded rod can further knead and crush the crushed material.

[0057] The relatively rotating first hollow rotating part drives the kneaded and crushed material into the fine crushing assembly to form an 8-shaped kneading path. Finally, the waste material is kneaded by the rough crushing assembly and the fine crushing assembly to the corresponding particle size and is blown out from the discharge port by the wind.

[0058] From the above application process, it can be known that the kneading powder machine provided by the present application mainly utilizes the impact force and the kneading friction in the process of crushing the waste material. Compared with the ball mill which utilizes the mutual impact between the steel balls, the kneading powder machine can effectively reduce the adverse effects of noise on the working environment and the health of the personnel. In addition, the power of the motor used in the kneading powder machine can be reduced to 10KW, and the power consumption per hour can be reduced to 10 degrees / hour. Compared with the ball mill (the motor used in the ball mill is 55KW, and the power consumption is 55 degrees / hour) and the rough crusher (the motor used in the rough crusher is 37KW, and the power consumption is 37 degrees / hour) in the prior art, the kneading powder machine has the advantages of energy saving and consumption reduction. Moreover, the kneading powder machine provided by the present application also has the advantages of simple structure, small size, convenience and the like.

[0059] Third, after the fine grinding process, the fine grinding material is stored in the bin by vacuum suction. The elbow of each pipeline of the bin is grounded to effectively release the static electricity generated by the accumulated fine material at the elbow, thereby avoiding the risk of fire caused by static electricity. In addition, a temperature probe is installed on the vacuum pump to realize alarm when the temperature exceeds the set temperature, thereby avoiding high-temperature operation. Furthermore, protective gas such as nitrogen is injected during vacuum suction to reduce the risk of fire.

[0060] Fourth, a constant temperature storage tank is added beside the kneader to store raw materials, so as to ensure that the temperature of the raw materials is the same. Cooling devices are installed on the extrusion cylinder and screw of the extruder to avoid the problem that the temperature of the equipment is too high during extrusion, so that the strip cannot be extruded or the quality of the extruded strip is inconsistent. That is, the changes of climate / environmental temperature and storage time, etc. cause the kneading efficiency of this process and the extrusion effect of the subsequent process to be poor, etc. Finally, the quality of the carbon molecular sieve produced in different batches is basically consistent, that is, the product quality stability of the carbon molecular sieve is high.

[0080] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects more clearly understood, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

The meaning of "several" is one or more, unless explicitly specified otherwise.

For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0085] The fine material ground by the prior art is vacuumed into the bin, and then the fine material is transported from the bin to the kneader for mixing. The mixed material at least includes phenolic resin and coal tar. The viscosity and activity of phenolic resin and coal tar change with the change of climate / environmental temperature and the length of storage time, etc., which leads to the poor kneading efficiency of this process and the poor extrusion effect of the subsequent process, and finally makes the quality of carbon molecular sieve produced in different batches inconsistent, i.e. the product quality of carbon molecular sieve is unstable.

[0086] In view of the technical problems existing in the prior art, the embodiments of the present application provide a carbon molecular sieve production system and method for reducing the energy consumption of carbon molecular sieve production and improving the quality of carbon molecular sieve.

[0087] In a first aspect, referring to Figure 1 The carbon molecular sieve production system provided by the embodiments of the present application comprises a feeding device 1, a rubbing powder machine 2, a drying device 4, a rubbing powder machine 2, a kneading mixer 6, an extruder 7, a screening machine 8, a carbonization furnace 9 and a deposition furnace 10.

[0088] The feeding device 1 is used to supply the flower mud base material to the next process. The feeding device 1 can be any feeding device 1 provided by the prior art, for example, a conveying belt, a conveying cylinder or manual conveying. The flower mud base material can be a head material, a corner material or the like. The flower mud material or the corner material is used as a raw material for preparing the nitrogen-carbon molecule to replace the coal raw material used in the prior art. The flower mud material or the corner material contains abundant large pores, medium pores and micro pores, especially a large amount of micro pores and sub-micro pores required by the carbon molecular sieve adsorption (in actual application, the large pores and small pores are often used as channels for gas transmission, and the micro pores and sub-micro pores are used as pores for containing oxygen. Nitrogen is difficult to enter the micro pores and sub-micro pores, and thus is isolated outside the carbon molecular sieve to realize the separation of oxygen and nitrogen. ), that is, the flower mud material or the corner material is equivalent to an abundant “pore bank”. Compared with the coal raw material, the self characteristics of the flower mud material or the corner material make the control of the carbon molecular sieve pore size easy, and thus the quality of the carbon molecular sieve prepared by using the flower mud material or the corner material can be effectively improved. In addition, the flower mud material or the corner material is a non-renewable material, and there is no problem of excessive consumption of limited resources. In addition, there is no problem of air pollution in the production process.

[0089] The rubbing powder machine 2 is designed and manufactured based on the rubbing principle, is arranged at the coarse crushing station, is used to receive the flower mud base material input by the feeding device 1, rubs and crushes the flower mud base material, and then uses the airflow with the first preset strength to convey the coarse crushed material meeting the first preset particle size to the coarse crushed material bin 3.

[0090] The drying device 4 receives the coarse crushed material of the preset weight input by the coarse crushed material bin 3, and dries the coarse crushed material according to the preset drying temperature and the preset time; the dried coarse crushed material that meets the requirements after detection is transported to the temporary storage bin. As an example, the drying device 4 can specifically include a drying machine, the inner container of which is a detachable inner container; an electronic overhead scale is arranged above the drying machine and is used to weigh the tare weight of the inner container; a weighbridge, after the tare weight of the inner container is determined, the inner container is displaced to the weighbridge, and it is ensured that the inner container is located below the coarse crushed material bin 3; the inner container receives the coarse crushed material input by the coarse crushed material bin 3, and whether the coarse crushed material contained in the inner container reaches the preset weight is measured by the ground scale. In actual application, the inner container of the drying machine is taken out, and the tare weight of the inner container is weighed by the electronic overhead scale arranged above the drying machine. The inner container is placed on the weighbridge, and it is ensured that the inner container is located below the coarse crushed material bin 3. The discharge valve of the coarse crushed material bin 3 is opened to transport the coarse crushed material to the inner container, and at the same time, the weight of the coarse crushed material added to the inner container is obtained in real time by the weighbridge, and when the measured weight of the coarse crushed material is equal to the preset weight, the discharge valve is closed. The inner container containing the coarse crushed material of the preset weight is placed in the drying machine again.

[0091] In the above technical solution, the measuring instrument (i.e., the electronic overhead scale and the weighbridge) is arranged in the drying process, so that the contained amount of the coarse crushed material can be kept consistent. In the case that the preset drying temperature and the preset time arranged each time are basically consistent, the drying effect of different batches of coarse crushed material can be basically kept consistent. Therefore, the subsequent process can be stabilized, and the instability of the quality of the carbon molecular sieve can be reduced.

[0092] As an example, laboratory tests are performed on the dried coarse crushed material of each batch, mainly to test the moisture content and volatile matter indicators of the dried coarse crushed material, so as to ensure that the moisture content is 4%-6% and the volatile matter is 40%-45%.

[0093] The rubbing powder machine 2 is designed and manufactured based on the rubbing principle, is arranged at the fine crushing station, receives the coarse crushed material input by the temporary storage bin, rubs and crushes the coarse crushed material, and transports the fine powder meeting the second preset particle size to the fine crushed material bin 5 by using the airflow with the second preset intensity. The fine crushed material bin 5 is a constant-temperature bin.

[0094] As a possible implementation, the fine powder meeting the second preset granularity is transported to the fine crushing bin 5 by using a vacuum suction machine; each bend of the pipeline included in the vacuum suction machine is grounded; a temperature detector and a temperature alarm are arranged on the vacuum pump included in the vacuum suction machine; when the working temperature of the vacuum pump detected by the temperature detector exceeds a preset temperature, the temperature alarm is triggered to alarm; the vacuum suction machine is also configured with a protective gas supply device, which absorbs protective gas while absorbing the fine powder.

[0095] In practical application, it is found that the vacuum powder suction process is prone to fire problems. To solve this problem, the embodiment of the present application has the following solutions: 1. Grounding at all bends of the pipeline to release static electricity and avoid fire caused by static electricity accumulation. 2. Installing a temperature detector on the vacuum pump to realize alarm when the temperature exceeds the set temperature and avoid high-temperature operation. 3. Delivering nitrogen gas together with the vacuum powder suction, which greatly reduces the possibility of fire during the whole powder suction process.

[0096] The kneading mixer 6 is used to add the fine powder, resin and coal tar stored at constant temperature into the kneading mixer 6 according to a preset mass ratio, and to knead the materials in the kneading mixer 6 to form the raw material.

[0097] In practical application, it is found that the raw materials do not have a constant temperature device before being fed into the kneader, and the viscosity and activity of the phenolic resin and coal tar in the raw materials will change with the temperature change and storage time, which leads to unstable product quality of different batches. Especially, the change of the viscosity of the raw materials due to different climate temperatures will directly affect the kneading time and the effect of the extrusion, which will also cause instability in the subsequent processes and finally lead to unstable product quality.

[0098] To solve the above technical problems, the embodiment of the present application provides a possible implementation, which adds a constant temperature storage tank beside the kneader to store the raw materials and ensure that the raw materials have the same temperature. The cooling device is installed on the extrusion cylinder and screw of the extruder 7 to avoid the situation that the raw material cannot be extruded or the quality of the extruded raw material is inconsistent due to the high temperature of the equipment during extrusion.

[0099] The extruder 7 is configured with a constant temperature storage tank, and the raw material is temporarily stored in the constant temperature storage tank; the constant temperature raw material output from the constant temperature storage tank is transported to the extrusion cylinder included in the extruder 7 and the extrusion screw arranged in the extrusion cylinder, and the raw material is extruded to form a raw material strip by using the extrusion screw. As an example, the cooling device of the extrusion cylinder and screw starts to work after the extruder 7 works for 20-30 minutes.

[0100] The screening machine 8 receives the raw material strip output from the extruder 7, screens the raw material strip meeting the preset size by using the screening machine 8, and cools the raw material strip to a first preset temperature. The extruded raw material strip is put into the screening machine 8 for screening and ash screening, and finally the selected raw material strip is put into a basket for cooling.

[0101] Carbonization furnace 9 receives raw material strips output from screen bar machine 8, carbonizes them at a preset carbonization temperature to form carbonized strips, and cools them to a second preset temperature. Nitrogen gas is introduced into carbonization furnace 9 during the carbonization process. The cooled raw material strips are then loaded into carbonization furnace 9, and nitrogen gas is added simultaneously for electric heating carbonization at 700-900℃ to form carbonized strips. The carbonized strips are then allowed to cool statically.

[0102] The deposition furnace 10 receives the carbonized strips output from the carbonization furnace 9 and deposits them to form deposited strips. During the deposition process, a pore size modulation solution is added multiple times while nitrogen gas is introduced. After each addition of the pore size modulation solution, the deposited strips are sampled and tested. The test parameters include at least the amount of exhaust gas from the deposited strip in the nitrogen generator, the purity of the nitrogen gas, and the hardness of the deposited strip. Deposited strips that meet the test requirements are conveyed to the next process. Deposited strips that do not meet the test requirements are deposited again until the test results meet the requirements. After the deposited strips that meet the test requirements are screened, they form carbon molecular sieves.

[0103] The carbon molecular sieve production system provided in this embodiment of the invention also includes a sieving and crushing device 11. After the qualified carbon molecular sieve is cooled to a certain temperature (generally not lower than 70°C), it is sieved by the sieving and crushing device 11 and then bagged (the bag is put into the packaging barrel 12 in advance). At the same time, nitrogen gas is filled for protection. After the set weight is filled, the nitrogen gas pipe is pulled out and the plastic bag is tied tightly and sealed. Finally, the lid of the packaging barrel 12 is closed, a sealing label and product label are inserted, and it is put into storage.

[0104] See Figures 2 to 5As a possible implementation, the kneading powder machine 2 comprises a crushing box 20, a coarse crushing assembly 21, a fine crushing assembly 22, a motor 23 and a transmission assembly 24. The side wall of the crushing box 20 is provided with adjacent feed inlet 200 and air inlet 201, and the top wall of the crushing box 20 is provided with discharge outlet; the coarse crushing assembly 21 is arranged in the crushing box 20 and close to the feed inlet 200; the coarse crushing assembly 21 comprises a cylindrical first hollow rotating part 210 extending from one side wall to the other side wall of the crushing box 20, and a plurality of first threaded rods 211 arranged outside the cylindrical first hollow rotating part 210, the plurality of first threaded rods 211 are arranged at intervals and extend from one side wall to the other side wall of the crushing box 20; there is a gap between the cylindrical first hollow rotating part 210 and the first threaded rods 211. The fine crushing assembly 22 is arranged in the crushing box 20 close to the air inlet 201; the fine crushing assembly 22 comprises a cylindrical second hollow rotating part 220 extending from one side wall to the other side wall of the crushing box 20, and a plurality of second threaded rods 221 arranged outside the cylindrical second hollow rotating part 220, the plurality of second threaded rods 221 are arranged at intervals and extend from one side wall to the other side wall of the crushing box 20; there is a gap between the second hollow rotating part 220 and the second threaded rods 221; the second hollow rotating part 220 and the first hollow rotating part 210 rotate in opposite directions; the coarse crushing assembly 21 and the fine crushing assembly 22 are adjacent and through. The motor 23 is arranged at one end outside the crushing box 20. The power input end of the transmission assembly 24 is connected with the power output end of the motor 23, and the power output end of the transmission assembly 24 is connected with the first hollow rotating part 210 and the second hollow rotating part 220 respectively.

[0105] In the above technical solution, the coarse grinding and fine grinding processes adopt the kneading powder machine 2. In actual application, the motor 23 is started, and the first hollow rotating part 210 in the coarse crushing assembly 21 and the second hollow rotating part 220 in the fine crushing assembly 22 are driven to rotate in opposite directions by the transmission assembly 24, and air is blown to the discharge outlet during the relative rotation. Based on this, waste materials such as head materials and corner materials can be transported into the crushing box 20 through the feed inlet 200, and the rotating first hollow rotating part 210 can make the waste materials reciprocate and impact on the inner wall of the hollow rotating part at various positions to crush the waste materials with large size. After crushing, the waste materials fall into the gap between the first threaded rods 211 through the hollow positions of the first hollow rotating part 210. At this time, the friction between the rotating first hollow rotating part 210 and the crushed materials and the first threaded rods 211 further crushes the materials.

[0106] The relative rotation of the first hollow rotating part 210 drives the crushed materials to the fine crushing assembly 22, forming an 8-shaped kneading path, and finally, the waste materials are kneaded by the coarse crushing assembly 21 and the fine crushing assembly 22 to the corresponding particle size and then blown out of the discharge outlet by the air.

[0107] From the above application process, it can be known that the rubbing powder machine 2 provided by the application mainly utilizes the impact force and rubbing friction force in the process of crushing waste materials, and compared with the mutual impact between steel balls in the ball mill, the rubbing powder machine 2 can effectively reduce the adverse effects of noise on the working environment and the health of personnel. In addition, the power of the motor 23 used by the rubbing powder machine 2 provided by the application can be reduced to 10 KW, and the power consumption per hour can be reduced to 10 degrees / hour, which has the advantages of energy saving and consumption reduction compared with the ball mill (the motor 23 used by the ball mill is 55 KW, and the power consumption is 55 degrees / hour) and the coarse crusher (the motor 23 used by the coarse crusher is 37 KW, and the power consumption is 37 degrees / hour). Moreover, the rubbing powder machine 2 provided by the application also has the advantages of simple structure, small size, convenience and the like.

[0108] As a possible implementation manner, in the case that the first preset strength is equal to the second preset strength and the first preset particle size is greater than the second preset particle size, the discharge cylinder 25 of the rubbing powder machine 2 arranged on the coarse crushing station is H1, the discharge cylinder 25 of the rubbing powder machine 2 arranged on the fine crushing station is H2, and H2>H1. It needs to be further explained that the rubbing crushed crushed materials are blown out of the discharge cylinder 25 by the convection generated by the relatively rotating first and second hollow rotating parts 210. Therefore, when the length of the discharge cylinder 25 is relatively short, the crushed materials with a larger particle size can also be blown out. When the length of the discharge cylinder 25 is relatively long, the weight of the crushed materials downward is greater than the blowing force upward, at this time, the crushed materials with a larger particle size are not easy to be blown out of the discharge cylinder 25, but fall back to the coarse crushing assembly 21 and / or the fine crushing assembly 22 to continue to be rubbed. In view of this, when it is needed to rub the waste materials to the crushed materials with a smaller particle size, the length of the discharge cylinder 25 can be designed to be relatively long, and when it is needed to rub the waste materials to the crushed materials with a larger particle size, the length of the discharge cylinder 25 can be designed to be relatively short.

[0109] As a possible implementation manner, the first hollow rotating part 210 includes a face-shaped end cover, a ring-shaped end cover and a plurality of coarse crushing plates. The face-shaped end cover is arranged on the inner side of one side wall of the crushing box 20 close to the transmission assembly 24.

Both ends of each coarse crushing plate are connected to the face-shaped end cover and the ring-shaped end cover, respectively, and the plurality of coarse crushing plates are combined in a circular ring shape. It needs to be further explained that the face-shaped end cover and the ring-shaped end cover mainly bear the plurality of coarse crushing plates, and the opening of the ring-shaped end cover is arranged opposite to the feeding port 200 to ensure that the waste materials can smoothly enter into the interior of the first hollow rotating part 210 through the feeding port 200 and the opening of the ring-shaped end cover. The interior here refers to the interior region enclosed by the face-shaped end cover and the plurality of coarse crushing plates.

[0110] As a possible implementation manner, the second hollow rotating part 220 comprises a face-shaped end cover, a ring-shaped end cover and a plurality of fine crushing plates.

Two ends of each fine crushing plate are connected to the face-shaped end cover and the ring-shaped end cover respectively, and the plurality of coarse crushing plates are combined in a circular ring shape. The specific structure of the second hollow rotating part 220 is basically the same as that of the first hollow rotating part 210, and the difference between the two is that the number of the fine crushing plates is greater than that of the coarse crushing plates. That is, the distribution of the fine crushing plates is more dense than that of the coarse crushing plates.

Start the motor, and drive the first hollow rotating part in the coarse crushing component and the second hollow rotating part in the fine crushing component to rotate relative to each other through the transmission component. During the relative rotation, air is generated and blown towards the discharge port. S21. The floral foam base material or coarse crushed material is fed into the crushing box through the feed inlet. The rotating first hollow rotating part causes the floral foam base material or coarse crushed material to repeatedly impact at various positions on the inner wall of the hollow rotating part in order to crush the larger floral foam base material or coarse crushed material. S22. After crushing, the material falls into the gap between the first hollowed-out rotating part and the first threaded rod through the hollowed-out position of the first hollowed-out rotating part; at this time, the friction between the rotating first hollowed-out rotating part and the crushed material, and between the crushed material and the first threaded rod, further crushes the crushed material. S23. The first hollow rotating part rotates relative to each other, driving the crushed material into the fine crushing component, forming an 8-shaped crushing path. Finally, the flower clay base material or coarse crushed material is crushed to the corresponding particle size by the coarse crushing component and the fine crushing component and then blown out from the outlet by the wind.

8. The method for producing carbon molecular sieves according to claim 6, characterized in that, In steps S11 and S13, when the first preset strength is equal to the second preset strength and the first preset particle size is greater than the second preset particle size, the discharge cylinder of the kneading powder machine set at the coarse crushing station is H1, and the discharge cylinder of the kneading powder machine set at the fine crushing station is H2, where H2 > H1.

9. The method for producing carbon molecular sieves according to claim 6, characterized in that, The following method is used to convey fine powder that meets the second preset particle size to the fine crushing silo: A vacuum feeder is used to transport fine powder that meets a second preset particle size to a fine crushing hopper; each bend in the pipeline included in the vacuum feeder is grounded; the vacuum pump included in the vacuum feeder is equipped with a temperature detector and a temperature alarm, and when the operating temperature of the vacuum pump detected by the temperature detector exceeds the preset temperature, the temperature alarm is triggered; the vacuum feeder is also equipped with a protective gas supply device, which absorbs protective gas while the vacuum feeder is absorbing fine powder.

10. The method for producing carbon molecular sieves according to claim 6, characterized in that, S12 specifically includes the following steps: S120. Remove the inner drum of the dryer and weigh the tare weight of the inner drum using an electronic crane scale located above the dryer; S121. Place the inner liner on the weighbridge, ensuring that the inner liner is located below the coarse crushing bin; S121. Open the discharge valve of the coarse crushing hopper to transport the coarse crushing material to the inner liner. At the same time, the weight of the coarse crushing material added to the inner liner is obtained in real time through the weighbridge. When the actual weight of the coarse crushing material is equal to the preset weight, close the discharge valve. S122. Place the inner liner containing the preset weight of coarse crushed material back into the dryer; S123. Set the preset drying temperature of the dryer to 200-400℃ and the preset time to 120-180 minutes, and start the dryer to bake the coarse crushed material.
