Description

Technical Field

[0001] This utility model relates to the field of chemical particle drying technology, specifically a drying device for chemical particles. Background Technology

[0002] Chemical particles are tiny solid particles with specific forms, properties and applications in the chemical field. Drying is a key step in the production and processing of chemical particles. Drying can remove residual moisture from chemical particles and ensure chemical stability.

[0003] A Chinese patent with publication number CN221706034U discloses a drying device for plastic granules, including a base plate and a left and right upright plate respectively fixedly connected to the top sides of the base plate. A fixing ring is fixedly connected to the surface of each of the left and right upright plates, and a drying drum is rotatably connected to the surface of each fixing ring. This invention can help the plastic granules inside the drying drum to turn over better, thereby improving the overall efficiency of drying the plastic granules and facilitating normal unloading after drying. It solves the problem that in some current devices, plastic granules tend to accumulate inside the drying chamber, affecting the overall drying efficiency, and that in some devices, the plastic granules are difficult to discharge properly after use, leading to material loss.

[0004] The aforementioned drying device for plastic granules cannot effectively break up the agglomeration and deposition between chemical granules. The granules tend to accumulate locally, and cannot be evenly heated in a dispersed state. This makes it difficult to ensure that all granules are effectively and thoroughly dried, affecting the drying quality and effect. Furthermore, there are temperature dead zones and temperature stratification within the tank, which prevents the chemical granules from being heated evenly, affecting the drying rate and effect. Therefore, a drying device for chemical granules is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes a drying device for chemical particles.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A drying device for chemical particles according to this utility model includes a base, a box body fixedly connected to the base, and tank bodies rotatably mounted on both sides of the box body. The tank bodies have multiple guide holes, and spiral blades are fixed on the inner wall of the tank bodies. Gear rings are fitted at both ends of the circumferential surface of the tank bodies. Rotating columns are rotatably mounted on both sides of the box body, and gears are fitted at both ends of the rotating columns, with each gear meshing with a corresponding gear ring. A first pulley is fitted at one end of the rotating column. A first L-shaped plate is fixedly connected to one side of the box body, and a second L-shaped plate is fixedly connected to the other side of the box body. A rotating hollow rod is rotatably mounted on the first and second L-shaped plates, and the rotating hollow rod is disposed inside the tank body and located at the center of the tank body. Multiple stirring blades are fixed on the outer surface of the rotating hollow rod. Multiple air jets are provided on the hollow rotating rod. A second pulley is fitted to one end of the hollow rotating rod. A conveyor belt is fitted between the first and second pulleys. During the drying process, the electric motor drives the rotating column to rotate two gears and the first pulley. The gears force the gear ring to rotate, which in turn drives the tank to rotate. With the help of the conveyor belt, the second pulley drives the hollow rotating rod and the stirring blades to rotate. The stirring blades and the tank rotate in opposite directions. The rotation of the tank causes the particles to tumble as a whole, while the counter-rotation of the stirring blades generates a shear force opposite to the direction of particle movement, breaking up the agglomeration and deposition between particles and forming a three-dimensional turbulent flow pattern. This avoids local accumulation of chemical particles, keeps the particles in a more dispersed state, ensures that all particles can be heated evenly, and ensures that all particles can be effectively and thoroughly dried, thus guaranteeing the drying effect of the chemical particles and improving the drying quality of the chemical particles.

[0007] Preferably, the top side of the housing has an opening, and a heating chamber is fixed inside the opening. Multiple heating tubes are installed inside the heating chamber. One side of the heating chamber is connected to an air pipe channel, and the other end of the air pipe channel is rotatably connected to the port of a rotating hollow rod. Two air inlets are opened on the top side of the heating chamber, each with a grille. A fan is installed on the grille. When drying the chemical particles, a certain amount of chemical particles is added to the tank. Through the operation of the fan, and with the assistance of the heating tubes, the heated high-temperature gas is blown into the tank through the guide holes. Simultaneously, some of the high-temperature gas generated by the heating tube flows into the rotating hollow rod through the gas pipe channel and is finally ejected through the jet holes. The guide holes are evenly distributed on the side wall of the tank, ensuring that the high-temperature gas enters the tank from multiple directions, forming an outer heating flow. The jet holes of the rotating hollow rod radiate airflow from the center outward, forming a central heating flow. Through the three-dimensional heating network of outer wrapping and central penetration, the temperature dead zones inside the tank are completely eliminated, the temperature stratification phenomenon inside the tank is broken, and the temperature distribution inside the tank is more uniform. This facilitates uniform heating of chemical particles and improves the drying rate and effect.

[0008] Preferably, one end of the tank has a feed inlet and the other end has a discharge outlet. The tank is inclined downwards. When using the device, the feed inlet facilitates the feeding of plastic granules to be dried into the tank, and the discharge outlet facilitates the discharge of dried chemical granules.

[0009] Preferably, a control panel is installed on one side wall of the base, and the control panel is used to control the start and stop of the motor, fan and heating tube. When using the device, by setting up the control panel, the start and stop of multiple drive devices can be centrally controlled together, which greatly improves the convenience of operation.

[0010] The advantages of this utility model are:

[0011] 1. In the process of drying chemical particles, a certain amount of chemical particles are added into the tank. With the help of a fan and heating tubes, the heated high-temperature gas is blown into the tank through the guide holes. At the same time, part of the high-temperature gas generated by the heating tubes flows into the rotating hollow rod through the air pipe channel and is finally ejected through the jet hole. The guide holes are evenly distributed on the side wall of the tank to ensure that the high-temperature gas enters the tank from multiple directions, forming an outer heating flow. The jet hole of the rotating hollow rod radiates airflow from the center outward, forming a central heating flow. Through the three-dimensional heating network of outer wrapping and central penetration, the temperature dead zone inside the tank is completely eliminated, the temperature stratification phenomenon inside the tank is broken, and the temperature distribution inside the tank is more uniform. This makes it easier for the chemical particles to be heated evenly, thus improving the drying rate and effect.

[0012] 2. In the drying process of this invention, the operation of the electric motor drives the rotating column to rotate two gears and the first pulley. The gears force the gear ring to rotate, which in turn drives the tank to rotate. With the cooperation of the conveyor belt, the second pulley drives the rotating hollow rod and the stirring blades to rotate. The stirring blades and the tank rotate in opposite directions. The rotation of the tank causes the particles to tumble as a whole, while the counter-rotation of the stirring blades generates a shear force opposite to the direction of particle movement, breaking up the agglomeration and deposition between particles and forming a three-dimensional turbulent flow mode. This avoids local accumulation of chemical particles, keeps the particles in a more dispersed state, ensures that all particles can be heated evenly, and ensures that all particles can be effectively and thoroughly dried, thus guaranteeing the drying effect of chemical particles and improving the drying quality of chemical particles.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-5 As shown, a drying device for chemical particles includes a base 1, a housing 2 fixedly connected to the base 1, and a tank 3 rotatably mounted on both sides of the housing 2. The tank 3 has multiple guide holes 4, and a spiral blade 7 is fixed on the inner wall of the tank 3. Gear rings 8 are fitted at both ends of the circumferential surface of the tank 3. Rotating columns 9 are rotatably mounted on both sides of the housing 2, and gears 10 are fitted at both ends of the rotating columns 9. Each gear 10 meshes with a corresponding gear ring 8. The end is fitted with a first pulley 12. A first L-shaped plate 13 is fixed to one side of the tank 2, and a second L-shaped plate 14 is fixed to the other side of the tank 2. A rotating hollow rod 15 is rotatably mounted on the first L-shaped plate 13 and the second L-shaped plate 14. The rotating hollow rod 15 is located inside the tank 3 and at the center of the tank 3. Multiple stirring blades 16 are fixed on the outer surface of the rotating hollow rod 15. Multiple air jet holes 17 are opened on the rotating hollow rod 15. One end of the rotating hollow rod 15 is fitted with a first pulley 12. A second pulley 18 is provided, and a conveyor belt 19 is fitted around the first pulley 12 and the second pulley 18. During operation, in the drying process, the motor 11 drives the rotating column 9 to rotate the two gears 10 and the first pulley 12. The gears 10 force the toothed ring 8 to rotate, and the toothed ring 8 drives the tank body 3 to rotate. With the cooperation of the conveyor belt 19, the second pulley 18 rotates, which in turn causes the rotating hollow rod 15 and the stirring blade 16 to rotate. The stirring blade 16 and the tank body 3 rotate in opposite directions. The rotation of the tank body 3 causes the particles to tumble as a whole, while the reverse rotation of the stirring blade 16 generates a shearing force opposite to the direction of particle movement, breaking up the agglomeration and deposition between particles, forming a three-dimensional turbulent flow mode, avoiding local accumulation of chemical particles, and keeping the particles in a more dispersed state. This ensures that all particles can be heated evenly, ensuring that all particles can be effectively and thoroughly dried, guaranteeing the drying effect of chemical particles, and improving the drying quality of chemical particles.

[0022] By setting the spiral blades 7, the residence time of chemical particles in the tank 3 can be extended. During the rotation of the tank 3, the spiral blades 7 will have a certain obstruction and guiding effect on the particles, making the movement path of the particles in the tank 3 longer, thereby increasing the contact time between the particles and the hot air. The longer residence time means that the particles have more time to absorb heat and evaporate moisture, further ensuring the drying effect and improving the drying quality of chemical particles.

[0023] The top side of the housing 2 has an opening, and a heating box 20 is fixed inside the opening. Multiple heating tubes 22 are installed inside the heating box 20. One side of the heating box 20 is connected to an air pipe channel 23, and the other end of the air pipe channel 23 is rotatably connected to the port of a rotating hollow rod 15. Two air inlets are opened on the top side of the heating box 20, and each air inlet is equipped with a grille. A fan 21 is installed on the grille. During operation, when drying the chemical granules, a certain amount of chemical granules is first added to the tank 3 through the feed inlet 5. Then, the fan 21, in conjunction with the heating tubes 22, blows the heated high-temperature gas into the tank 3 through the guide hole 4, thereby drying the plastic granules inside the tank 3. The particles are dried, and at the same time, some of the high-temperature gas generated by heating through heating tube 22 flows into the rotating hollow rod 15 through gas pipe channel 23, and finally is ejected through jet hole 17, so that the high-temperature gas comes into contact with the chemical particles. The guide hole 4 is evenly distributed on the side wall of the tank 3 to ensure that the high-temperature gas enters the tank 3 from multiple directions, forming an outer heating flow. The jet hole 17 of the rotating hollow rod 15 radiates airflow from the center outward, forming a central heating flow. Through the three-dimensional heating network of outer wrapping and central penetration, the temperature dead zone inside the tank is completely eliminated, the temperature stratification phenomenon inside the tank 3 is broken, and the temperature distribution inside the tank 3 is more uniform, which makes it easier for the chemical particles to be heated evenly, thus improving the drying rate and effect.

[0024] Please see Figure 1-2 As shown, a feed inlet 5 is provided at one end of the tank body 3, and a discharge outlet 6 is provided at the other end of the tank body 3. The tank body 3 is inclined downward. When using this device, the feed inlet 5 facilitates the feeding of plastic granules to be dried into the tank body 3, and the discharge outlet 6 facilitates the discharge of dried chemical granules.

[0025] A control panel 24 is installed on one side wall of the base 1, and the control panel 24 is used to control the start and stop of the motor 11, the fan 21 and the heating tube 22. When using this device, by setting up the control panel 24, the start and stop of multiple drive devices can be centrally controlled together, which greatly improves the convenience of operation.

[0026] Working Principle: Existing drying devices for plastic granules cannot effectively break up the agglomeration and deposition of chemical granules, leading to localized granule accumulation. This prevents all granules from being evenly heated in a dispersed state, making it difficult to ensure thorough drying and affecting the drying quality and effect. Furthermore, temperature dead zones and stratification exist within the tank, resulting in uneven heating of the chemical granules and impacting the drying rate and effect. Therefore, a new drying device for chemical granules is proposed to address these issues. When drying chemical granules, a certain amount of chemical granules is first added to the tank 3 through the feed inlet 5. Then, a blower 21, in conjunction with the heating element 22, blows heated high-temperature gas into the tank 3 through the guide hole 4, thereby achieving... The device is capable of drying the plastic granules inside the tank 3. At the same time, some of the high-temperature gas generated by heating through the heating tube 22 flows into the rotating hollow rod 15 through the air pipe channel 23 and is finally ejected through the jet hole 17, so that the high-temperature gas comes into contact with the chemical granules. The guide holes 4 are evenly distributed on the side wall of the tank 3 to ensure that the high-temperature gas enters the tank 3 from multiple directions, forming an outer heating flow. The jet hole 17 of the rotating hollow rod 15 radiates airflow from the center outward, forming a central heating flow. Through the three-dimensional heating network of outer wrapping and central penetration, the temperature dead zone inside the tank is completely eliminated, the temperature stratification phenomenon inside the tank 3 is broken, and the temperature distribution inside the tank 3 is more uniform, which makes it easier for the chemical granules to be heated evenly, thus improving the drying rate and effect.

[0027] During the drying process, the motor 11 drives the rotating column 9 to rotate the two gears 10 and the first pulley 12. The gears 10 force the gear ring 8 to rotate, which in turn drives the tank body 3 to rotate. With the cooperation of the conveyor belt 19, the second pulley 18 rotates, which in turn causes the rotating hollow rod 15 and the stirring blade 16 to rotate. The stirring blade 16 and the tank body 3 rotate in opposite directions. The rotation of the tank body 3 causes the particles to tumble as a whole, while the reverse rotation of the stirring blade 16 generates a shearing force opposite to the direction of particle movement. This breaks up the agglomeration and deposition between particles, forming a three-dimensional turbulent flow pattern. This avoids local accumulation of chemical particles, keeps the particles in a more dispersed state, ensures that all particles can be heated evenly, and ensures that all particles can be effectively and thoroughly dried. This guarantees the drying effect of the chemical particles and improves the drying quality of the chemical particles.

[0028] By setting the spiral blades 7, the residence time of chemical particles in the tank 3 can be extended. During the rotation of the tank 3, the spiral blades 7 will have a certain obstruction and guiding effect on the particles, making the movement path of the particles in the tank 3 longer, thereby increasing the contact time between the particles and the hot air. The longer residence time means that the particles have more time to absorb heat and evaporate moisture, further ensuring the drying effect and improving the drying quality of chemical particles.
