Abstract
Description
Technical Field
[0001] The invention relates to the technical field of dryers, in particular to a double-effect dryer for cellulose with a crushing function. Background Art
[0002] Traditional cellulose drying is done by using a dragon to push the airflow to dry it. After passing through a drying tower and a cyclone separator, the cellulose falls into a grinder. After the cellulose is crushed, the remaining material returns to the grinder and is crushed again.
[0003] During the use of the dryer, the cellulose raw materials will contain moisture during the cellulose production process, so they need to be dried to control the moisture content. After the cellulose is produced, the cellulose needs to be crushed. After the cellulose is crushed, the cellulose particles are too small and contain too much moisture. During the stirring process, the cellulose will gather together to form thick blocks. In the drying process, only the moisture on the surface of the thick blocks will be affected by the heat, and the moisture inside the thick blocks will be less affected by the heat. The overall drying effect is low, and because the cellulose particles are small, they are easily attached to the inner wall of the drum. After working for a long time, the cellulose attached to the inner wall of the drum will continue to be affected by high temperature, and eventually the cellulose will be damaged due to the long-term high temperature. Summary of the Invention
[0004] The object of the present invention is to provide a double-effect dryer for cellulose with a crushing function to solve the problems raised in the prior art.
[0005] To achieve the above object, the present invention provides the following technical solutions:
[0006] The dryer includes a cylinder assembly, a driving assembly and a crushing assembly. The cylinder assembly is provided with a driving assembly, and the driving assembly is provided with a crushing assembly for crushing the cellulose. A stirring assembly is provided at one end of the driving assembly for stirring the cellulose. A detection assembly is provided in the stirring assembly.
[0007] Specifically, since the cellulose raw materials will contain moisture during the cellulose production process, they need to be dried to control the moisture content. After the cellulose is produced, the cellulose needs to be crushed. After the cellulose is crushed, the cellulose particles are too small and contain too much moisture. During the stirring process, the cellulose will gather together to form thick blocks. In the drying process, only the moisture on the surface of the thick blocks will be affected by the heat, and the moisture inside the thick blocks will be less affected by the heat. The overall drying effect is low, and since the cellulose particles are small, they are easily attached to the inner wall of the drum. The crushing component is used to crush the cellulose in the middle part of the drum, and the stirring component is used to stir the crushed cellulose, thereby increasing the overall activity of the cellulose, accelerating the drying effect, and preventing the cellulose from forming a thick layer during the stirring process. The detection component is used to clean the cellulose attached to the inner wall of the drum according to the detection structure control component.
[0008] The stirring assembly includes a scraper, a scraping block, a base and a rotating block. The scraper is located at one end of the connecting tube and is fixedly connected to one end of the connecting tube. A scraping block is provided between the scraper and the connecting tube and is fixedly connected to the scraper. A groove is provided on the scraper and the groove is used to collect cellulose. A base is provided at one end of the groove and is fixedly connected to the groove. An electrode is provided on the base and a pushing assembly is provided in the groove and the pushing assembly is used to clean the cellulose in the groove. The rotating block is located in the drum and is used to clean the cellulose remaining on the inner wall of the drum.
[0009] Specifically, the stirring assembly is used to stir the cellulose in one end of the drum, and the scraper is fixedly connected to the outer wall of the connecting cylinder. There are multiple scrapers, and the scraper and the connecting cylinder are on the same central axis. A scraping block is provided between the scraper and the connecting cylinder. The scraper will be close to the inner wall of the drum during the stirring process, and the scraping block will be in the middle layer of the cellulose during the stirring process, so that the scraping block cooperates with the scraper to stir the entire cellulose. The connecting rod on the scraper is provided with a groove, and the groove is located between the scraper and the connecting cylinder. The groove is used to collect cellulose of different densities. Due to the centrifugal force generated by the rotation of the drum and the activity of the liquid, its water molecules will gather at the inner wall of the drum, which will cause the water content of the cellulose close to the drum to be higher than the water content of the cellulose close to the central axis, resulting in different water content of the cellulose on both sides, which will lead to different drying efficiency on both sides during drying. When the scraper connecting rod contacts the cellulose, because there are multiple grooves, the cellulose of different densities will adhere to different grooves. When the cellulose attached to the groove contacts the electrode, the electrode will The moisture content of cellulose produces different test results. When the electrode contacts the cellulose, the higher its moisture content, the higher the overall conductivity of the cellulose, and the greater the current generated. According to the current value difference of different grooves, the overall rotation speed of the drum is adjusted. The greater the current value difference, the faster the drum speed, which improves the cellulose drying effect. The scraper is used to turn the cellulose over as a whole. The faster the drum speed, the faster the turning. Even if the cellulose is stirred, it is easy to adhere to the inner wall of the drum because the cellulose particles themselves are small. Because the scraper edge is close to the inner wall of the drum, after working for a long time, the inner wall of the drum and the cellulose will wear the scraper edge, which will increase the distance between the scraper and the inner wall of the drum. The cellulose at the bottom will stick to the inner wall of the drum due to the high moisture content, the squeezing of the cellulose and the squeezing of the scraper. As the drying time increases, the cellulose on the inner wall will be fixed on the inner wall, so it is necessary to make it fall off before the cellulose on the inner wall is damaged due to drying. The rotating block in the drum is used to clean the cellulose remaining on the inner wall of the drum, and its rotating block is connected to the drum rotation.
[0010] The driving assembly includes a first rotating motor and a connecting tube. A flat plate is provided at the bottom end of the first rotating motor, and the bottom end of the first rotating motor is fixedly connected to the flat plate. A connecting tube is provided at the output end of the first rotating motor, and the output end of the first rotating motor is fixedly connected to the connecting tube. A crushing assembly is provided in the middle of the connecting tube, and a stirring assembly is provided at one end of the connecting tube.
[0011] Specifically, the driving assembly is used to control the rotation of the connecting cylinder. The rotation of the connecting cylinder will drive the crushing assembly and the stirring assembly to rotate, and then process the cellulose in the drum. The drum is located in the middle of the flat plate, the first rotating motor is located at one end of the drum, and a drying assembly is provided at the other end of the drum. The connecting cylinder and the drum are on the same central axis, and the output end of the first rotating motor faces the drum. The first rotating motor is used as a power source to control the rotation of the connecting cylinder. The rotation direction of the connecting cylinder is opposite to the rotation direction of the drum. The crushing assembly is located in the middle of the connecting cylinder, and the stirring assembly is located at the end of the connecting cylinder away from the driving assembly. When the cellulose enters the drum, the cellulose will contact the crushing assembly and then contact the stirring assembly.
[0012] The cylinder assembly includes a drum and a second rotating motor. A flat plate is provided at the bottom end of the drum, and the drum is rotatably connected to the flat plate. A second rotating motor is provided at the top of the flat plate, and the fixed end of the second rotating motor is fixedly connected to the flat plate. The output end of the second rotating motor is rotatably connected to the drum. A blower is provided on the upper surface of the flat plate, and the blower is located at the end of the flat plate away from the first rotating motor, and the output end of the blower is aligned with one end of the drum.
[0013] Specifically, the drum assembly serves as the overall main structure of the dryer, the drum is rotatably connected to the flat plate, the second rotating motor is located between the drum and the flat plate, the outer drum body of the drum is provided with a thread, and the thread cooperates with the output end of the second rotating motor. The second rotating motor serves as a power source for controlling the rotation of the drum. The second rotating motor is affected by the electrode detection structure. When the cellulose just crushed enters the stirring assembly, the blower is used to provide a heat source for providing hot air. The power of the hot air is controlled according to the current value generated by the electrode. Only when one of the current values is greater than the set value, that is, when there is still cellulose, the cellulose When there are water molecules, the blower will enter the working mode. The greater the current value, the greater the wind speed and heat. The end of the drum close to the first rotating motor is provided with a pouring port, and the end of the drum close to the blower is provided with a discharge port. Because the blower is close to the discharge port, when the wind force of the blower is strong, the cellulose at the stirring component is affected by the wind force and will not enter the discharge port. During the drying and stirring process, the water molecules in the cellulose will become fewer and fewer, the current value will become smaller and smaller, and the wind force and heat of the blower will also decrease, thereby coordinating with the rotation of the drum to slowly move the stirred cellulose to the discharge port.
[0014] The crushing assembly includes a main cutter and an auxiliary cutter. The main cutter is located in the middle of the connecting cylinder. The main cutter is fixedly connected to the connecting cylinder. The main cutter is arranged in steps. The auxiliary cutter is fixedly connected to the inner wall of the drum. The main cutter and the auxiliary cutter are on the same central axis.
[0015] Specifically, the crushing assembly is used to crush cellulose, the main cutter is fixedly connected to the outer cylinder of the connecting cylinder, and the auxiliary cutter is fixedly connected to the inner wall of the drum, wherein the main cutter and the auxiliary cutter are arranged and installed along the same central axis, and the main cutter is installed in a stepped arrangement, with the main cutter close to the first rotating motor as the low point, and the main cutter close to the second rotating motor as the high point, so that the cellulose is broken into fine particles by the crushing assembly.
[0016] The pushing component includes a driving motor and a pushing block. The driving motor is located at both ends of the inner wall of the groove. The fixed end of the driving motor is fixedly connected to the inner wall of the groove. A scraper is provided at the output end of the driving motor.
[0017] Specifically, the pushing component is used to clean the cellulose in the groove to facilitate the next humidity detection. The driving motor is used as a power source to control the movement of the scraper. The scraper moves along the inner wall of the groove. The output end of the driving motor is fixedly connected to the scraper.
[0018] A rotating groove is provided on the inner wall of the drum, which is located at one end of the drum close to the connecting cylinder. A rotating block is provided in the rotating groove, which is rotatably connected to the rotating groove. A stretching component is provided between the rotating block and the rotating groove.
[0019] Specifically, a rotating groove is opened on the inner wall of the drum, and the rotating block is located in the rotating groove. The rotating block is rotatably connected to the rotating groove. The movement of the rotating block is controlled by the stretching assembly. The rotating block is used to clean the cellulose remaining on the inner wall to prevent the cellulose from being attached to the inner wall of the drum.
[0020] The detection component includes a main capacitor block and a first auxiliary capacitor block. The first auxiliary capacitor block is provided in the scraper, and the scraper is fixedly connected to the first auxiliary capacitor block. The second auxiliary capacitor block is provided on the flat plate, and the main capacitor block is provided on the inner wall of the drum, and the main capacitor block is fixedly connected to the drum.
[0021] Specifically, the detection component is used to detect the rotation position of the roller, the rotating block and the connecting cylinder. The rotation of the connecting cylinder drives the scraper to rotate, and the scraper drives the first auxiliary capacitor block to move. The position of the cylinder is known through the three capacitor blocks. The number of main capacitor blocks corresponds to the number of rotating blocks. As long as the main capacitor block is at the top and the first auxiliary capacitor block is not between the main capacitor block and the second auxiliary capacitor block, that is, the capacitance value between the main capacitor block and the second auxiliary capacitor block reaches the maximum value and is not affected by the first auxiliary capacitor block, this electrical signal is used to control the operation of the stretching component to rotate the rotating block, and then when the capacitance value between the main capacitor block and the first auxiliary capacitor block reaches the set value, that is, the main capacitor block and the first auxiliary capacitor block are on the same central axis, this electrical signal is used to control the operation of the pushing component.
[0022] The stretching assembly includes a sealing ring and a pushing motor. The sealing ring is located on the surface of the rotating block. The fixed end of the pushing motor is fixedly connected to the inner wall of the groove. The output end of the pushing motor is rotatably connected to the rotating block.
[0023] Specifically, the stretching assembly is used to control the rotation of the rotating block. The sealing ring is located on the side of the rotating block close to the connecting cylinder. The sealing ring is used to prevent cellulose from leaking into the groove. The pushing motor serves as a power source to control the rotating block to move in an arc shape. The pushing motor will only push the rotating block to move when the capacitance value between the main capacitor block and the first auxiliary capacitor block reaches a set value. The pushing motor controls the rotating block to cooperate with the groove in a normal state, so that the surface of the rotating block and the inner wall of the drum are in the same plane.
[0024] Compared with the prior art, the present invention has the following beneficial effects:
[0025] 1. The present invention controls the rotation of the connecting cylinder through the first driving component, and the connecting cylinder drives the scraper to rotate. The scraper contacts the cellulose during rotation, thereby breaking up the thick layer of cellulose, thereby preventing the cellulose in the drum from having a poor drying effect due to the thick layer.
[0026] 2. The grooves on the scraper of the present invention will adhere to cellulose of different layers when rotating. When the cellulose attached to the grooves contacts the electrodes, the electrodes will generate corresponding current values according to the water content of the cellulose attached to the grooves. The drying effect and water content of the cellulose of different layers can be judged according to the numerical value of the current value and the difference between the current values, and the rotation speed of the connecting cylinder and the drum and the power of the blower can be controlled to improve the stirring effect and drying effect.
[0027] 3. In the present invention, as the scraper rotates, the scraper edge is close to the inner wall of the drum. After working for a long time, the inner wall of the drum and the cellulose will wear the scraper edge, which will increase the distance between the scraper and the inner wall of the drum. The cellulose particles themselves are small and can easily adhere to the inner wall of the drum. As long as the main capacitor block is at the top and the first sub-capacitor block is not between the main capacitor block and the second sub-capacitor block, that is, the capacitance value between the main capacitor block and the second sub-capacitor block reaches the maximum value and is not affected by the first sub-capacitor block, this electrical signal is used to control the operation of the stretching component. The rotating block will squeeze the cellulose remaining on the inner wall to make it fall off, preventing the cellulose from being attached to the inner wall of the drum.
[0028] 4. The blower of the present invention is close to the discharge port, so when the wind force of the blower is strong, the cellulose at the stirring component is affected by the wind force and will not enter the discharge port. During the drying and stirring process, the water molecules in the cellulose will become fewer and fewer, the current value will become smaller and smaller, and the wind force and heat of the blower will also decrease, thereby cooperating with the rotation of the drum to slowly move the stirred cellulose to the discharge port.

[0039] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
[0040] Example: Figures 1 to 9As shown, the present invention provides a technical solution for a double-effect dryer for cellulose with a crushing function. The dryer includes a cylinder assembly 1, a drive assembly 2 and a crushing assembly 3. The cylinder assembly 1 is provided with a drive assembly 2, and the drive assembly 2 is provided with a crushing assembly 3. The crushing assembly 3 is used to crush the cellulose. A stirring assembly 4 is provided at one end of the drive assembly 2. The stirring assembly 4 is used to stir the cellulose. A detection assembly 5 is provided in the stirring assembly 4.
[0041] Specifically, since the cellulose raw materials will contain moisture during the cellulose production process, they need to be dried to control the moisture content. After the cellulose is produced, the cellulose needs to be crushed. After the cellulose is crushed, the cellulose particles are too small and contain too much moisture. During the stirring process, the cellulose will gather together to form thick blocks. During the drying process, only the moisture on the surface of the thick blocks will be affected by the heat, and the moisture inside the thick blocks will be less affected by the heat. The overall drying effect is low, and since the cellulose particles are small, they are easily attached to the inner wall of the drum 11. The crushing component 3 is used to crush the cellulose in the middle part of the drum 11, and the stirring component 4 is used to stir the crushed cellulose to improve the overall activity of the cellulose, speed up the drying effect, and prevent the cellulose from forming a thick layer during the stirring process. The detection component 5 is used to clean the cellulose attached to the inner wall of the drum 11 according to the detection structure control component.
[0042] like Figures 3 to 6 As shown, the stirring assembly 4 includes a scraper 41, a scraping block 42, a base 43 and a rotating block 44. The scraper 41 is located at one end of the connecting cylinder 22, and the scraper 41 is fixedly connected to one end of the connecting cylinder 22. A scraping block 42 is provided between the scraper 41 and the connecting cylinder 22, and the scraping block 42 is fixedly connected to the scraper 41. A groove 411 is provided on the scraper 41, and the groove 411 is used to collect cellulose. A base 43 is provided at one end of the groove 411, and the base 43 is fixedly connected to the groove 411. An electrode 45 is provided on the base 43, and a pushing assembly 6 is provided in the groove 411. The pushing assembly 6 is used to clean the cellulose in the groove 411. The rotating block 44 is located in the drum 11, and the rotating block 44 is used to clean the cellulose remaining on the inner wall of the drum 11.
[0043] Specifically, the stirring assembly 4 is used to stir the cellulose in one end of the drum 11, and the scraper 41 is fixedly connected to the outer wall of the connecting cylinder 22. There are multiple scrapers 41, and the scrapers 41 and the connecting cylinder 22 are on the same central axis. A scraper block 42 is provided between the scraper 41 and the connecting cylinder 22. The scraper 41 will be close to the inner wall of the drum 11 during the stirring process, and the scraper block 42 will be in the middle layer of the cellulose during the stirring process, so that the scraper block 42 cooperates with the scraper 41 to stir the entire cellulose. The connecting rod on the scraper 41 is provided with a groove 411, and the groove 411 is located between the scraper 41 and the connecting cylinder 22. 11 is used to collect cellulose of different layers. Due to the centrifugal force generated by the rotation of the drum 11 and the mobility of the liquid, its water molecules will gather on the inner wall of the drum 11, which will cause the water content of the cellulose close to the drum 11 to be higher than the water content of the cellulose close to the central axis, resulting in different water contents of the cellulose on both sides. When drying, it will cause different drying efficiencies on both sides. When the connecting rod of the scraper 41 contacts the cellulose, since there are multiple grooves 411, the cellulose of different layers will adhere to different grooves 411. When the cellulose attached to the grooves 411 contacts the electrodes 45, the electrodes 45 will move. 5 will produce different detection results according to the water content of the cellulose attached to the groove 411. When the electrode 45 contacts the cellulose, the higher the water content, the higher the overall conductivity of the cellulose, and the greater the current generated. According to the current value difference of different grooves 411, the overall rotation speed of the drum 11 is adjusted. The greater the current value difference, the faster the rotation speed of the drum 11, which improves the cellulose drying effect. The scraper 41 is used to turn the cellulose over as a whole. The faster the rotation speed of the drum 11, the faster the turning speed. Even if the cellulose is stirred, the cellulose particles themselves are small and easily attached to the inner wall of the drum 11. Because the scraper 41 The blade 41 is close to the inner wall of the drum 11. After a long period of operation, the inner wall of the drum 11 and the cellulose will wear the blade of the scraper 41, thereby increasing the distance between the scraper 41 and the inner wall of the drum 11. The cellulose at the bottom will be pressed against the inner wall of the drum 11 due to the high water content, the squeezing of the cellulose and the scraper 41. As the drying time increases, the cellulose on the inner wall will be fixed to the inner wall. Therefore, it is necessary to remove the cellulose on the inner wall before it is damaged by drying. The rotating block 44 in the drum 11 is used to clean the cellulose remaining on the inner wall of the drum 11. The rotating block 44 is rotatably connected to the drum 11.

The bottom end of the first rotating motor 21 is provided with a flat plate 13, and the bottom end of the first rotating motor 21 is fixedly connected to the flat plate 13. The output end of the first rotating motor 21 is provided with a connecting tube 22, and the output end of the first rotating motor 21 is fixedly connected to the connecting tube 22. A crushing assembly 3 is provided in the middle of the connecting tube 22, and a stirring assembly 4 is provided at one end of the connecting tube 22.
[0045] Specifically, the driving component 2 is used to control the rotation of the connecting cylinder 22. The rotation of the connecting cylinder 22 will drive the crushing component 3 and the stirring component 4 to rotate, and then the cellulose in the drum 11 is processed. The drum 11 is located in the middle of the flat plate 13, and the first rotating motor 21 is located at one end of the drum 11. The other end of the drum 11 is provided with a drying component. The connecting cylinder 22 and the drum 11 are on the same central axis, and the output end of the first rotating motor 21 faces the drum 11. The first rotating motor 21 is used as a power source to control the rotation of the connecting cylinder 22. The rotation direction of the connecting cylinder 22 is opposite to the rotation direction of the drum 11. The crushing component 3 is located in the middle of the connecting cylinder 22, and the stirring component 4 is located at the end of the connecting cylinder 22 away from the driving component 2. When the cellulose enters the drum 11, the cellulose will contact the crushing component 3 and then contact the stirring component 4.
[0046] like Figure 1 、 Figure 2 As shown, the cylinder assembly 1 includes a drum 11 and a second rotating motor 12. A flat plate 13 is provided at the bottom end of the drum 11.

The second rotary motor 12 is affected by the detection structure of the electrode 45. When the cellulose just crushed enters the stirring assembly 4, the blower 14 is used to provide a heat source for providing hot air. The power of the hot air is controlled according to the current value generated by the electrode 45. Only when one of the current values is greater than the set value, that is, the fiber There are also water molecules in the cellulose, the blower 14 will enter the working mode, the greater the current value, the greater the wind speed and heat, the drum 11 is close to the first rotating motor 21 at one end with a pouring port, the drum 11 is close to the blower 14 at one end with a discharge port. Because the blower 14 is close to the discharge port, when the blower 14 has a strong wind force, the cellulose at the stirring component 4 is affected by the wind force and will not enter the discharge port. During the drying and stirring process, the water molecules in the cellulose will become fewer and fewer, the current value will become smaller and smaller, and the wind force and heat of the blower 14 will also decrease, thereby cooperating with the rotation of the drum 11 to slowly move the stirred cellulose to the discharge port.

The output end of the driving motor 61 is fixedly connected to the scraper 63.
[0052] like Figure 7 As shown, a rotating groove is provided on the inner wall of the drum 11, which is located at one end of the drum 11 close to the connecting tube 22.

The main capacitor block 51 is provided on the inner wall of the drum 11, and the main capacitor block 51 is fixedly connected to the drum 11.
[0055] Specifically, the detection component 5 is used to detect the rotation position of the roller 11, the rotating block 44 and the connecting tube 22. The rotation of the connecting tube 22 drives the scraper 41 to rotate, and the scraper 41 drives the first auxiliary capacitor block 52 to move. The position of the cylinder is known through the three capacitor blocks. The number of main capacitor blocks 51 corresponds to the number of rotating blocks 44. As long as the main capacitor block 51 is at the top and the first auxiliary capacitor block 52 is not between the main capacitor block 51 and the second auxiliary capacitor block 53, that is, the capacitance value between the main capacitor block 51 and the second auxiliary capacitor block 53 reaches the maximum value and is not affected by the first auxiliary capacitor block 52, this electrical signal is used to control the operation of the stretching component 7 to rotate the rotating block 44. Then, when the capacitance value between the main capacitor block 51 and the first auxiliary capacitor block 52 reaches the set value, that is, the main capacitor block 51 and the first auxiliary capacitor block 52 are on the same central axis, this electrical signal is used to control the operation of the pushing component 6.
[0056] like Figure 7 As shown, the stretching assembly 7 includes a sealing ring 71 and a pushing motor 72. The sealing ring 71 is located on the surface of the rotating block 44. The fixed end of the pushing motor 72 is fixedly connected to the inner wall of the groove 411. The output end of the pushing motor 72 is rotatably connected to the rotating block 44.
[0057] Specifically, the stretching assembly 7 is used to control the rotation of the rotating block 44. The sealing ring 71 is located on the side of the rotating block 44 close to the connecting tube 22. The sealing ring 71 is used to prevent cellulose from leaking into the groove 411. The pushing motor 72 serves as a power source to control the rotating block 44 to move in an arc shape. The pushing motor 72 will only push the rotating block 44 to move when the capacitance value between the main capacitor block 51 and the first auxiliary capacitor block 52 reaches a set value. The pushing motor 72 controls the rotating block 44 to cooperate with the groove 411 in the normal state, so that the surface of the rotating block 44 and the inner wall of the drum 11 are in the same plane.
[0058] Working principle: A discharge port is provided at one end of the drum 11, and the cellulose raw material enters the drum 11 from the discharge port. The raw material will enter the crushing component 3 through the rotation of the drum 11, and the crushing component 3 will drive the main tool 31 and the auxiliary tool 32 to rotate through the drum 11 and the connecting cylinder 22 to crush the cellulose raw material. The crushed cellulose enters the stirring component 4, and the cellulose particles will aggregate together to form a thick layer due to their own particle size and the water molecules they contain. The first driving component 2 controls the rotation of the connecting cylinder 22, and the connecting cylinder 22 drives the scraper 41 to rotate. The scraper 41 will contact the cellulose during rotation, and then break up the thick layer of cellulose. Because the blade of the scraper 41 is close to the inner wall of the drum 11, after working for a long time, the inner wall of the drum 11 and the cellulose will wear the blade of the scraper 41, which will increase the distance between the scraper 41 and the inner wall of the drum 11. The cellulose particles themselves are small and can easily adhere to the inner wall of the drum 11. As long as the main capacitor When the block 51 is at the top and the first auxiliary capacitor block 52 is not between the main capacitor block 51 and the second auxiliary capacitor block 53, that is, the capacitance value between the main capacitor block 51 and the second auxiliary capacitor block 53 reaches the maximum value and is not affected by the first auxiliary capacitor block 52. This electrical signal is used to control the operation of the stretching component 7. The rotating block 44 will squeeze the cellulose remaining on the inner wall to make it fall off, preventing the cellulose from always sticking to the inner wall of the drum 11. Then, when the stirring component 4 is working, the groove 411 on the scraper 41 will adhere to different layers of cellulose. When the cellulose attached to the groove 411 contacts the electrode 45, the electrode 45 will generate a corresponding current value according to the water content of the cellulose attached to the groove 411. The drying effect and moisture content of the cellulose of different layers are judged according to the numerical value of the current value and the difference between the current values, and then the rotation speed of the connecting cylinder 22 and the drum 11 and the power of the blower 14 are controlled to improve the stirring effect and drying effect.
