Description

Technical Field

[0001] The invention relates to the technical field of polymer drying, in particular to a polymer drying device. Background Art

[0002] Fluidized bed drying is a highly efficient polymer drying technology. Its principle is that when gas flows upward through a solid particle layer at a certain speed, the solid particles present a fluidized state similar to that of a liquid. The hot air flow passes between the suspended particles, dynamically exchanges heat, and takes away the moisture or solvent in the material. The fluidized bed has high heat and mass transfer efficiency, which can enable the material to quickly meet the drying requirements and has excellent drying uniformity. The material particles are constantly fluidized and tumbled, avoiding local uneven drying.

[0003] Although fluidized bed can provide extremely high-quality polymer drying effect, there are still certain problems when using fluidized bed drying: during the drying process of polymer, as the solvent gradually evaporates, the distance between polymer particles continues to decrease. This change leads to a significant enhancement of the molecular interaction on the particle surface. From the perspective of surface tension, each polymer particle has a certain surface energy, and they tend to reduce the overall surface energy by approaching and combining with each other. The effect of this surface tension is like an invisible force, causing the particles to attract each other, especially in the drying of aqueous polymer emulsions. Water as a solvent gradually dissipates, and the polymer particles originally dispersed in the emulsion begin to approach each other. The surface tension plays a role at this time, causing these particles to attract each other, especially at the beginning of drying, the solvent content is relatively high, the polymer particles are fully wrapped and dispersed by the solvent, and the distance between the particles is large. As drying proceeds, the solvent evaporates rapidly and the distance between particles decreases rapidly. At this time, the effect of surface tension begins to increase significantly, causing the tendency of particles to attract each other to increase rapidly. This results in a large number of agglomerated polymers in the initial stage of polymer drying. These agglomerated polymers cannot be carried upward by the hot air flow and will block the pores of the air distribution plate, resulting in the air flow being unable to flow out normally from the pores of the air distribution plate, thereby affecting the fluidization effect of the polymer and causing the polymer to be unable to be fully dried. Based on the above viewpoints, the present invention provides a polymer drying device. Summary of the invention

[0015] Preferably, an air suction pump is installed at an upper position of the left side wall of the fluidized chamber, and an air suction pipe is installed on the input end of the air suction pump. Several branches of the air suction pipe pass through the left side wall of the fluidized chamber and are arranged above the fixed air distribution plate group. A one-way valve is connected to the output end of the air suction pump through a pipeline, and an air storage chamber is connected to the output end of the one-way valve. The air storage chamber is installed at a rear position of the front side wall of the fluidized chamber, and an exhaust valve is connected to the bottom of the air storage chamber through a pipeline. The output end of the exhaust valve is connected to an exhaust box through a pipeline, and the exhaust box passes through the left side wall of the fluidized chamber. A gravity air distribution plate group is installed on the rear side wall of the fixed air distribution plate group, and the exhaust box is arranged below the gravity air distribution plate group.

[0016] The present invention has the following technical points and beneficial effects:

[0017] 1. The suction pump collects part of the gas produced in the initial stage of fluidized drying of the polymer through the suction pipe. Since this part of the gas contains a high amount of water vapor, the suction pump will regularly draw part of the gas in the fluidized chamber into the gas storage chamber to maintain the heat of the gas in the gas storage chamber and prevent the gas in the gas storage chamber from condensing. The gas released to the bottom of the gravity air distribution plate group will rise with the hot air and contact the polymer, thereby increasing the water content of the air in the rear section of the fluidized chamber, avoiding excessive drying of the polymer and causing it to form on the gravity air distribution plate group. At the same time, the humidified air can significantly reduce the amount of static electricity in the environment.

[0018] 2. After the granular polymer falls into the dispensing barrel, the hot air entering from the main air inlet pipe will move the polymer from the particle outlet to the vibrating chassis. At the same time, the hot air entering from the bottom will blow the driving blades to rotate, thereby driving the dispensing barrel to rotate through the driving rod. Under the influence of the vibration of the vibrating chassis and the directional vibration of the vibration motor, the polymer particles and the anti-static balls that fall into the vibrating chassis will move together in the direction of the material receiving box. Due to the difference in elastic force between the polymer particles and the anti-static balls, the anti-static balls will continuously contact the polymer particles at different positions, and the static electricity accumulated in the polymer will be transmitted when it contacts the anti-static balls. The charge in the anti-static ball will be transferred to the vibrating chassis and the pressure storage reflux cylinder during the bouncing process, and then conducted into the ground, effectively avoiding the accumulation of static electricity in the granular polymer and avoiding the occurrence of polymer agglomeration due to excessive static electricity accumulated in the polymer during the subsequent formal fluidization process. After the anti-static ball contacts the spring plate, the spring plate moves backward, and the original sealing plug moves forward compared to the spring plate. At this time, the reset air outlet is opened, and part of the hot air will be blown out from the air duct, and then the anti-static ball is reset by the hot air, so that the anti-static ball bounces repeatedly above the vibrating chassis, thereby increasing the static electricity elimination efficiency.

[0019] 3. When the hot air cannot drive the floating polymer lumps to fall into the distributing barrel, the hot air blown out from the main air inlet pipe blows the polymer lumps to the side wall of the distributing barrel. At the same time, since the distributing barrel rotates and the hot air blowing position is fixed, the polymer lumps that fall into the distributing barrel will be blown back and forth by the hot air, and then hit the inner wall of the distributing barrel, so that the polymer lumps will dissipate. When the distributing barrel rotates, the telescopic tube sleeve will continuously contact the protrusions of the telescopic tooth pattern plate of the polymer breaking cone, so that the telescopic tube sleeve will continue to extend compared to the distributing barrel. The extended polymer breaking cone head can pierce the polymer lumps to dissipate the polymer lumps. The dispersion is more thorough. Taking into account that some polymers have high water content and high viscosity, the deagglomerate cone may lift them up and cannot ensure their effective dispersion. Therefore, the swinging deagglomerate mechanism can improve the polymer agglomerate dissipation rate. The swinging deagglomerate mechanism mainly relies on the hot air blown out of the main air inlet pipe to drive it to swing back and forth. At the same time, due to the rotation of the distribution barrel, the main air inlet pipe will drive the swinging deagglomerate mechanism to swing in turn. When the swinging deagglomerate mechanism swings, the deagglomerate beads continuously collide with the polymer agglomerates lifted up by the deagglomerate cone head, and the dispersion efficiency of the polymer agglomerates is improved through the impact of the deagglomerate beads.

[0020] 4. When a large number of polymer agglomerates fall into the distributing barrel together in a short period of time, and the hot air flow enters the pressure storage reflux barrel, the polymer blocks the bottom pores of the distributing barrel, and a large amount of gas and heat accumulate at the bottom of the pressure storage reflux barrel, causing the air pressure below the pressure storage reflux barrel to rise until it reaches the release threshold of the pressure relief valve. After the telescopic sleeve releases the gas, the polymer-breaking cone head will pop out quickly and puncture the agglomerate beads. Since the agglomerate beads store high-pressure gas inside, the small steel balls stored inside will splash out when the agglomerate beads are punctured. The agglomerate beads are made of material resistant to high temperature and high-pressure gas. Since several agglomerate beads explode and release small steel balls at the same time, the polymers agglomerated inside the distributing barrel are fully dispersed.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Embodiment 1: Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, an embodiment of the present invention provides a polymer drying device, including a fluidizing chamber 1, a buffer base 9 installed at the four corners of the bottom of the fluidizing chamber 1, a supporting base 3 installed at the bottom of the four buffer bases 9, a vibration motor 8 arranged on the right side wall of the fluidizing chamber 1, a hot air inlet pipe 5 penetrating the left side wall of the bottom of the fluidizing chamber 1, an exhaust pipe port 4 arranged at the upper rear side of the fluidizing chamber 1, a feeding port 2 installed in front of the fluidizing chamber 1 and a discharge port 7 installed in the middle position of the rear side wall of the fluidizing chamber 1, a fixed air distribution plate group 15 is installed on the inner side wall of the fluidizing chamber 1, and a plurality of gravity agglomeration processors 17 distributed in a rectangular array are embedded and installed on the front side of the plate body of the fixed air distribution plate group 15, and the gravity agglomeration processors 17 are arranged on the inner side wall of the fluidizing chamber 1. The processor 17 includes a fixed plate group 171, and the fixed plate group 171 includes a top fixed plate 1711. The lower side wall of the top fixed plate 1711 is fixedly connected with a pressure storage reflux cylinder 1712. The inner side wall of the top fixed plate 1711 is rotatably connected with a rotating frame 1713. The inner cavity of the rotating frame 1713 is connected with a distributing mechanism 172 through a plurality of springs distributed in a circular array. The distributing mechanism 172 includes a distributing cylinder 1721. A driving rod 1723 is fixedly connected to the middle position of the lower side wall of the distributing cylinder 1721. A driving fan blade 1724 is fixedly connected to the bottom of the driving rod 1723. A particle discharge port 1722 is opened in the middle position of the distributing cylinder 1721. The side air inlet mechanism 175 is fixedly connected to the outer wall and located at the bottom position of the particle discharge port 1722. The side air inlet mechanism 175 includes a main air inlet pipe 1751. The opening of the main air inlet pipe 1751 is upward and aligned with the top position of the right side wall of the particle discharge port 1722. The polymer particles to be dried are placed in the fluidizing chamber 1 from the feeding port 2. The polymer first falls onto the front end plate of the fixed air distribution plate group 15 densely covered with gravity-type agglomeration processors 17, and the vibration motor 8 drives the fluidizing chamber 1 to vibrate, so that the polymer scattered on the fixed air distribution plate group 15 is spread evenly, and the polymer is driven to move slowly toward the direction of the discharge port 7. At the same time, the hot air inlet pipe 5 will introduce hot air into the fluidizing chamber 1 from the bottom. The rising hot air will drive the polymer particles to be blown up and suspended, presenting a fluidized tumbling state like boiling. When the granular polymer falls into the distributing barrel 1721, the hot air entering from the main air inlet pipe 1751 will drive the polymer in and out from the particle discharge port 1722 to the vibration chassis 1771. When the hot air cannot drive the floating polymer clumps to fall into the distributing barrel 1721, the hot air blown out from the main air inlet pipe 1751 will blow the polymer clumps to a side wall of the distributing barrel 1721. At the same time, since the distributing barrel 1721 rotates and the hot air blowing position is fixed, the polymer clumps that fall into the distributing barrel will be blown back and forth by the hot air, and then hit the inner wall of the distributing barrel 1721, so that the polymer clumps can dissipate.

[0045] like Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.12 , Fig.13 and Fig.14 As shown, the lower side wall of the material distributing barrel 1721 is fixedly connected with a plurality of deagglomeration cone mechanisms 176 distributed in a circumferential array, and the deagglomeration cone mechanism 176 includes a limit tube 1761, and the limit tube 1761 is internally limited and slidably connected with a telescopic sleeve 1762, and a pressure relief valve 1763 is located at the lower part of the telescopic sleeve 1762. A deagglomeration cone head 1764 is installed inside the telescopic sleeve 1762 and above the pressure relief valve 1763, and a deagglomeration cone head 1764 is installed inside the pressure storage reflux barrel 1712 and at A deagglomeration cone telescopic toothed plate 178 is installed below the plurality of deagglomeration cone mechanisms 176. A plurality of swing-type deagglomeration mechanisms 173 distributed in a circumferential array are installed on the upper side of the inner wall of the material distributing barrel 1721. The swing-type deagglomeration mechanism 173 includes a mounting seat 1731. A cartridge changing compartment 1732 is provided inside the mounting seat 1731. A tough tube 1733 is fixedly connected below the mounting seat 1731. The tough tube 1733 is filled with deagglomeration beads 1734. When rotating, the telescopic sleeve 1762 continuously contacts the protrusion of the deagglomeration cone telescopic toothed plate 178, so that the telescopic sleeve 1762 is continuously extended compared to the distributing barrel 1721. The extended deagglomeration cone head 1764 can pierce the agglomerated polymer, so that the polymer agglomerates are dispersed more thoroughly. Considering that some polymers have a high water content and a high viscosity, the deagglomeration cone head 1764 may lift them up and cannot ensure that they are effectively dispersed. Therefore, the swing-type deagglomeration mechanism 173 can be used to The dissipation rate of polymer clumps is improved, and the swinging de-clumping mechanism 173 mainly relies on the hot air blown out by the main air inlet pipe 1751 to drive it to swing back and forth. At the same time, due to the rotation of the distribution barrel 1721, the main air inlet pipe 1751 will drive the swinging de-clumping mechanism 173 to swing in turn. When the swinging de-clumping mechanism 173 swings, the de-clumping beads 1734 continuously impact the polymer clumps lifted up by the de-clumping cone head 1764, and the impact of the de-clumping beads 1734 improves the dispersion efficiency of the polymer clumps.

[0046] like Fig. 9 , Fig.10 and Fig.11As shown, the driving gear plates 1714 are fixedly connected to the two sides of the rotating frame 1713, the top pin of the distributing barrel 1721 is connected to the barrel cover 1727, and the two ends of the shaft rod used to connect the barrel cover 1727 are fixedly connected to the barrel cover driving gears 1728, and the top pins on both sides of the distributing barrel 1721 are connected to the barrel cover transmission gears 1729, and the two barrel cover transmission gears 1729 are respectively meshed with the two barrel cover driving gears 1728, and the two barrel cover transmission gears 172 The rear sides of the pins are respectively engaged with the two driving tooth plates 1714, the outer wall of the material distributing cylinder 1721 is fixedly connected with a friction pad 1726 near the top, the bottom of the pressure storage reflux cylinder 1712 is limitedly slidably connected with a chassis vibration mechanism 177, the chassis vibration mechanism 177 includes a vibration chassis 1771, the bottom of the vibration chassis 1771 is fixedly connected with a chassis vibration transmission tooth pattern plate 1772, the outer wall of the driving rod 1723 is located directly below the chassis vibration transmission tooth pattern plate 1772 It is fixedly connected with a driving toothed plate 1725, which is used in conjunction with the chassis vibration transmission toothed plate 1772. When a large number of polymer lumps fall into the distribution barrel 1721 in a short period of time, the mass in the distribution barrel 1721 increases and begins to move downward gradually. When the distribution barrel 1721 moves downward, the barrel cover transmission gear 1729 contacts and rotates with the driving toothed plate 1714, and at the same time, the barrel cover driving gear 1728 will be driven to reverse, and the barrel cover 1727 is closed to prevent more polymer from entering the distribution barrel 1721. At the same time, the friction pad 1726 contacts the inner wall of the pressure storage reflux barrel 1712, and the friction force between the distribution barrel 1721 and the friction pad 1726 increases sharply, and the hot air can no longer drive the distribution barrel 1721 to rotate. This also means that the vibration chassis 1771 will no longer vibrate, avoiding the distribution barrel 1721 from rising due to the vibration of the vibration chassis 1771, and ensuring that the polymer inside the distribution barrel 1721 will not disperse.

[0047] Embodiment 2: Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14As shown, this embodiment provides another technical solution based on the first embodiment, the bottom of the front side wall of the pressure storage reflux cylinder 1712 is connected to a spring plate 1710 through a spring, and a reset air port 17101 is opened in the middle of the spring plate 1710, and the side air inlet mechanism 175 also includes an air duct 1752, one end of the air duct 1752 is fixedly connected to the narrow section of the main air inlet pipe 1751, and the other end of the main air inlet pipe 1751 is fixedly connected to the outer side wall of the pressure storage reflux cylinder 1712 and the front end of the spring plate 1710 is placed inside it, and a sealing plug 1753 is fixedly connected inside the other end of the air duct 1752, and the rear end lower limit of the sealing plug 1753 is slidably connected in the reset air port 17101, and the pressure storage reflux cylinder 171 2 and is provided with a discharge port at the bottom of the front side wall and below the reset air outlet 17101, the outer side wall of the top fixed plate 1711 is fixedly connected with the material receiving box 174, the discharge port provided on the front side wall of the pressure storage reflux cylinder 1712 is communicated with the interior of the material receiving box 174, and a plurality of anti-static balls 179 are provided on the upper side wall of the vibration chassis 1771. After the hot air flow enters the pressure storage reflux cylinder 1712, the bottom air holes of the distribution cylinder 1721 are blocked by the polymer, and a large amount of gas and heat accumulate at the bottom of the pressure storage reflux cylinder 1712, causing the air pressure below the pressure storage reflux cylinder 1712 to rise until it reaches the release threshold of the pressure relief valve 1763, and after the telescopic sleeve 1762 releases the gas, the polymer-breaking cone head 1764 will pop out quickly and pierce The broken ball 1734 stores high-pressure gas inside, so when the broken ball 1734 is punctured, the small steel balls stored inside will splash out. The broken ball 1734 is made of a material that can withstand high temperature and high-pressure gas. Since several broken balls 1734 explode and release small steel balls at the same time, the polymers gathered inside the distributing barrel 1721 are fully dispersed, and the dispersed polymers fall from the particle discharge port 1722 onto the vibration chassis 1771, and are discharged into the receiving box 174 after being destaticized. Under the action of hot air and vibration, it slowly moves to the rear side, and while the driving rod 1723 rotates, the toothed plate 1725 is driven to rotate together, thereby driving the vibration chassis 1771 to vibrate. Under the influence of the vibration of the vibration motor 71 and the directional vibration of the vibration motor 8, the polymer particles and the anti-static ball 179 that fall into the vibration chassis 1771 will move together in the direction of the material receiving box 174. Due to the difference in elasticity between the polymer particles and the anti-static ball 179, the anti-static ball 179 will continuously contact the polymer particles at different positions, and the static electricity accumulated in the polymer will be conducted when it contacts the anti-static ball 179. The charge in the anti-static ball 179 will be transferred to the vibration chassis 1771 and the pressure storage reflux cylinder 1712 during the bouncing process, and then conducted to the ground, effectively avoiding the accumulation of static electricity in the granular polymer, and avoiding the occurrence of polymer agglomeration due to excessive static electricity accumulated in the polymer during the subsequent formal fluidization process.

[0048] like Figure 1 , Figure 2 and Figure 4 As shown, an air suction pump 10 is installed at the upper position of the left side wall of the fluidizing chamber 1, and an air suction pipe 6 is installed on the input end of the air suction pump 10. Several branches of the air suction pipe 6 pass through the left side wall of the fluidizing chamber 1 and are arranged above the fixed air distribution plate group 15. A one-way valve 11 is connected to the output end of the air suction pump 10 through a pipeline, and an air storage chamber 12 is connected to the output end of the one-way valve 11. The air storage chamber 12 is installed at the rear position of the front side wall of the fluidizing chamber 1. An exhaust valve 13 is connected to the bottom of the air storage chamber 12 through a pipeline, and an output end of the exhaust valve 13 is connected to an exhaust box 14 through a pipeline. The exhaust box 14 passes through the left side wall of the fluidizing chamber 1, and a gravity air distribution plate group 16 is installed on the rear side wall of the fixed air distribution plate group 15. The exhaust box 14 is arranged below the gravity air distribution plate group 16. When a large amount of polymer moves to the gravity air distribution plate group 16, it will press the gravity air distribution plate group 16 to move slightly downward, moving The gravity air distribution plate group 16 triggers the pressure sensor at its bottom, thereby releasing the gas stored in the gas storage chamber 12 to the bottom of the gravity air distribution plate group 16. The gas in the gas storage chamber 12 is mainly collected in the polymer crushing process stage. The suction pump 10 collects part of the gas produced in the initial stage of polymer fluidization drying through the suction pipe 6. Since this part of the gas contains a high amount of water vapor, the suction pump 10 will regularly draw part of the gas in the fluidization chamber 1 into the gas storage chamber 12 to maintain the heat of the gas in the gas storage chamber 12 and prevent the gas in the gas storage chamber 12 from condensing. The gas released below the gravity air distribution plate group 16 will rise with the hot air and contact the polymer, thereby increasing the water content of the air in the rear section of the fluidization chamber 1 to avoid excessive drying of the polymer and causing it to clot on the gravity air distribution plate group 16. At the same time, the humidified air can significantly reduce the amount of static electricity in the environment.

[0049] Working principle: the polymer particles to be dried are placed into the fluidizing chamber 1 from the feeding port 2, and the polymer first falls onto the front end plate of the fixed air distribution plate group 15 densely covered with gravity-type agglomeration processor 17, and the vibration motor 8 drives the fluidizing chamber 1 to vibrate, thereby spreading the polymer scattered on the fixed air distribution plate group 15 evenly, and driving the polymer to move slowly toward the discharge port 7, and at the same time, the hot air inlet pipe 5 will introduce hot air into the bottom of the fluidizing chamber 1, and the rising hot air will drive the polymer particles to be blown up and suspended, showing a fluidized tumbling state like "boiling", and the top fixed plate 1711, the receiving box 174, the driving toothed plate 1725, the bottom of the distributing barrel 1721 and The chassis vibration mechanism 177 is provided with dense ventilation holes to meet the fluidization conditions when the polymer falls into the gravity agglomeration processor 17. When the granular polymer falls into the distributing barrel 1721, the hot air entering from the main air inlet pipe 1751 will move the polymer from the particle outlet 1722 to the vibration chassis 1771. At the same time, the narrow section of the main air inlet pipe 1751 can increase the flow rate of the hot air blown out, thereby preventing the polymer particles from being affected by the upward wind force when falling into the top fixed plate 1711. At the same time, the hot air entering from the bottom will blow the driving blades 1724 to rotate, thereby driving the distributing barrel 1721 to rotate through the driving rod 1723. While the driving rod 1723 is rotating, the driving toothed plate 1725 is rotated together, thereby driving the vibration chassis 1771 to vibrate. Under the influence of the vibration of the vibration chassis 1771 and the directional vibration of the vibration motor 8, the polymer particles and the anti-static ball 179 that fall into the vibration chassis 1771 will move together in the direction of the material receiving box 174. Due to the difference in elastic force between the polymer particles and the anti-static ball 179, the anti-static ball 179 will continuously contact the polymer particles at different positions, and the static electricity accumulated in the polymer will be conducted when it contacts the anti-static ball 179, and the charge in the anti-static ball 179 will be transferred to the vibration chassis 1771 during the bouncing process. 71 and the pressure storage reflux cylinder 1712, and then conducted into the ground, which effectively avoids the accumulation of static electricity in the granular polymer and the occurrence of polymer agglomeration due to excessive static electricity accumulated in the polymer during the subsequent formal fluidization process. After the anti-static ball 179 contacts the spring plate 1710, the spring plate 1710 moves backward, and the originally blocked plug 1753 moves forward compared to the spring plate 1710. At this time, the reset air outlet 17101 is opened, and part of the hot air will be blown out from the air duct 1752, and then the anti-static ball 179 is reset by the hot air, so that the anti-static ball 179 repeatedly bounces above the vibration chassis 1771, thereby increasing the static electricity elimination efficiency.

[0050] When the hot air cannot drive the floating polymer lumps to fall into the distributing barrel 1721, the hot air blown out from the main air inlet pipe 1751 blows the polymer lumps to the side wall of the distributing barrel 1721. At the same time, since the distributing barrel 1721 rotates and the hot air blowing position is fixed, the polymer lumps that fall into the distributing barrel 1721 will be blown back and forth by the hot air, and then hit the inner wall of the distributing barrel 1721, so that the polymer lumps will be dispersed. When the distributing barrel 1721 rotates, the telescopic tube sleeve 1762 continuously contacts the protrusion of the telescopic toothed plate 178 of the polymer breaker cone, so that the telescopic tube sleeve 1762 is continuously extended compared to the distributing barrel 1721. The extended polymer breaker cone head 1764 can be used to pierce the agglomerated polymer, so that the polymer lumps are eliminated. The dispersion is more thorough. Taking into account that some polymers have high water content and high viscosity, the deagglomerate cone head 1764 may lift them up and cannot ensure their effective dispersion. Therefore, the swinging deagglomerate mechanism 173 is used to improve the polymer agglomerate dissipation rate. The swinging deagglomerate mechanism 173 mainly relies on the hot air blown out by the main air inlet pipe 1751 to drive it to swing back and forth. At the same time, due to the rotation of the distribution barrel 1721, the main air inlet pipe 1751 will drive the swinging deagglomerate mechanism 173 to swing in turn. When the swinging deagglomerate mechanism 173 swings, the deagglomerate beads 1734 continuously impact the polymer agglomerates lifted up by the deagglomerate cone head 1764, and the dispersion efficiency of the polymer agglomerates is improved through the impact of the deagglomerate beads 1734.

[0051] When a large number of polymer lumps fall into the distributing barrel 1721 in a short period of time, the mass in the distributing barrel 1721 increases and begins to move downward gradually. When the distributing barrel 1721 moves downward, the barrel cover transmission gear 1729 contacts and rotates with the driving gear plate 1714, and at the same time, the barrel cover driving gear 1728 is driven to reverse, and the barrel cover 1727 is closed to prevent more polymer from entering the distributing barrel 1721. At the same time, the friction pad 1726 contacts the inner wall of the pressure storage reflux barrel 1712, and the distributing barrel 1721 The friction force between the friction pad 1726 increases sharply, and the hot air can no longer drive the distribution barrel 1721 to rotate. This also means that the vibration chassis 1771 will no longer vibrate, avoiding the distribution barrel 1721 from rising due to the vibration of the vibration chassis 1771, ensuring that the polymer inside the distribution barrel 1721 will not be scattered. At the same time, as the distribution barrel 1721 descends, the hot air blown out by the main air inlet pipe 1751 will not directly enter the distribution barrel 1721, avoiding the polymer inside the distribution barrel 1721 from being affected by pneumatics, ensuring The polymer is relatively still inside the distributing barrel 1721, and after the hot air flow enters the pressure storage reflux barrel 1712, the polymer blocks the bottom pores of the distributing barrel 1721, and a large amount of gas and heat accumulate at the bottom of the pressure storage reflux barrel 1712, causing the air pressure below the pressure storage reflux barrel 1712 to rise until it reaches the release threshold of the pressure relief valve 1763. After the telescopic sleeve 1762 releases the gas, the polymer breaking cone head 1764 will pop out quickly and pierce the breaking ball 1734. High-pressure gas is stored inside, so when the breaking beads 1734 are punctured, the small steel balls stored inside will splash out. The breaking beads 1734 are made of material resistant to high temperature and high-pressure gas. Since several breaking beads 1734 explode and release small steel balls at the same time, the polymers agglomerated inside the distributing barrel 1721 are fully dispersed, and the dispersed polymers will fall from the particle discharge port 1722 onto the vibrating chassis 1771, and after being destaticized, they are discharged into the receiving box 174, and slowly move to the rear under the action of hot air and vibration.

[0052] When a large amount of polymer moves onto the gravity air distribution plate group 16, it will press the gravity air distribution plate group 16 to move slightly downward. The moving gravity air distribution plate group 16 triggers the pressure sensor at its bottom, thereby releasing the gas stored in the gas storage chamber 12 to the bottom of the gravity air distribution plate group 16. The gas in the gas storage chamber 12 is mainly collected during the polymer crushing process. The suction pump 10 partially collects the gas produced in the initial stage of polymer fluidization drying through the suction pipe 6. Since this part of the gas contains a high amount of water vapor, the suction pump 10 will periodically draw part of the gas in the fluidization chamber 1 into the gas storage chamber 12 to maintain the heat of the gas in the gas storage chamber 12 and prevent the gas in the gas storage chamber 12 from condensing. The gas released below the gravity air distribution plate group 16 will rise with the hot air and contact the polymer, thereby increasing the water content of the air in the rear section of the fluidization chamber 1 to avoid excessive drying of the polymer and causing it to clot on the gravity air distribution plate group 16. At the same time, the humidified air can significantly reduce the amount of static electricity in the environment.
