Abstract
Description
Technical Field
[0001] The invention relates to the technical field of drying, and in particular to a cobalt hydroxide drying and calcining device. Background Art
[0002] A vibrating fluidized bed dryer is a highly efficient drying device that combines vibration technology with the principles of a fluidized bed. It is widely used in various industries. A vibrating fluidized bed dryer is often used when drying cobalt hydroxide.
[0003] In existing technology, vibrating fluidized bed dryers are based on the efficient combination of vibration drive and fluidization technology. They consist of a housing with a distribution plate mounted within. The distribution plate is equipped with multiple ventilation holes. A vibrating motor provides vibration, and hot air is injected beneath the distribution plate. This causes the material accumulated on the distribution plate to become liquid-like due to the combined effects of vibration and airflow. The particles tumble and mix vigorously, and the vibration drives the powdered material along the distribution plate from the feed inlet to the discharge outlet.
[0004] However, during the drying process, powdered materials can clump together and form agglomerates due to surface moisture or static electricity. Agglomerates can clog the ventilation holes on the distribution plate, hindering the upward flow of gas and affecting the fluidization of the material. This can lead to uneven distribution of the material on the distribution plate, affecting the uniformity of the material drying and, consequently, the consistency of the subsequent calcination. Summary of the Invention
[0005] The present invention provides a cobalt hydroxide drying and calcining device to solve the above problems.
[0006] The invention discloses a cobalt hydroxide drying and calcining device, which adopts the following technical solution: the cobalt hydroxide drying and calcining device comprises a base, a vertical partition plate, a guide plate, a vertical baffle plate, and an air supply component.
[0007] A housing is installed above the base, allowing it to move up and down. A vibration spring is connected between the housing and the base. The housing is arranged front and back, with an inlet at the front and an outlet at the rear. An exhaust outlet is located at the top of the housing. A vibration assembly is mounted on the housing. The vibration assembly includes a vibration motor, which is fixed to the housing. The air supply assembly includes a first fan and a second fan. The outlet of the first fan is connected to the first chamber via a first air duct, and the outlet of the second fan is connected to the second chamber via a second air duct. Electric heating wires are installed in both the first and second air ducts to heat the air.
[0008] The vertical partition is arranged in the shell; the vertical partition extends forward and backward and is fixed to the bottom wall of the shell; a distribution plate is fixed to the upper end of the vertical partition; a plurality of through holes are provided on the distribution plate; the distribution plate is fixedly connected to the inner wall of the shell.
[0009] The guide plate is arranged above the distribution plate; the guide plate is fixed on the inner wall of the shell; the length of the guide plate extends forward and backward; the guide plate is a V-shaped plate with the small end facing upward; the guide plate and the distribution plate divide the shell into an upper cavity, a middle cavity and a lower cavity.
[0010] The vertical baffle is located between the guide plate and the distribution plate. The baffle extends forward and backward, with its lower end fixed to the distribution plate. The baffle corresponds to the vertical partition in a vertically aligned manner. A separation gap is provided between the upper end of the baffle and the guide plate. The partition divides the lower chamber into a first chamber and a second chamber. The baffle divides the middle chamber into a third chamber and a fourth chamber. The portion of the guide plate corresponding to the third chamber is provided with multiple air holes. A dropout port is provided at the front end of the third chamber. The dropout port is located on the guide plate and communicates with the feed port. The third chamber communicates with the upper chamber. The first and third chambers communicate, while the second and fourth chambers communicate. The third and fourth chambers are connected via a separation gap. The portion of the distribution plate within the third chamber is wavy. A crushing assembly is also provided within the third chamber, which is used to crush agglomerated material on the portion of the distribution plate within the third chamber.
[0011] The air supply assembly is used to supply heat and air to the first and second chambers, and to ensure that the speed of the hot air in the third chamber is greater than that in the fourth chamber. After the material enters the third chamber, the powdered material is blown upward by the hot air in the third chamber and flows along the guide plate through the separation gap to the fourth chamber. Because the speed of the hot air in the third chamber is greater than that in the fourth chamber, the powdered material falls onto the portion of the distribution plate in the fourth chamber under the action of gravity and flows toward the discharge port with the vibration of the hot air. Agglomerated material retained on the wavy portion of the distribution plate collides with the wavy portion of the distribution plate under the action of the vibrating assembly, and the lumps collide with each other, which helps to disperse the lumps into powder. After the agglomerated material is dispersed into powder again, it continues to flow with the hot air in the third chamber toward the upper guide plate. After being guided by the guide plate, it flows into the fourth chamber through the separation gap for fluidized drying. That is, by setting the wind speed of the hot air in the third chamber to be greater than the wind speed of the hot air in the fourth chamber, the separation of powdered material and agglomerated material is achieved, and under the action of the vibration component, the agglomerates collide and disperse on the wavy part of the distribution plate, so that the agglomerates are gradually reduced, so that the material is evenly distributed on the distribution plate, ensuring the effect of fluidization of the material, which is conducive to improving the uniformity of material drying.
[0012] Furthermore, multiple crushing assemblies are distributed along the front-to-back direction. The crushing assemblies include a rotating shaft disposed within the third chamber, with both ends rotatably mounted on the outer shell. The rotating shaft is driven to rotate by a power structure. Multiple straight pressure wheels are coaxially fixed to the rotating shaft. An inclined pressure wheel is disposed between adjacent straight pressure wheels. An angle is formed between the axes of the inclined pressure wheels and the axis of the rotating shaft, such that the inclined pressure wheels and the straight pressure wheels form a V-shape. Agglomerates are located between the inclined pressure wheels and the straight pressure wheels, and when the rotating shaft rotates, the inclined pressure wheels rotate, pushing the agglomerates toward the straight pressure wheels and squeezing them, causing the agglomerates to break and disperse.
[0013] Furthermore, the power structure includes a pulley and a synchronous belt; the pulley is fixed to the end of the rotating shaft; the synchronous belt is sleeved on the pulleys on the rotating shafts of the multiple crushing components; and the synchronous belt and the pulley are meshed.
[0014] Furthermore, an auxiliary structure is provided in the fourth cavity; the auxiliary structure is used to move the material when the thickness of the material distribution on the distribution plate in the fourth cavity is uneven, so as to promote uniform distribution of the material.
[0015] Furthermore, the auxiliary structure is arranged in the fourth cavity and above the distribution plate, including a push rod, an inner ring, and an outer ring; the axis of the push rod is arranged radially along the rotating shaft; a matching hole is provided on the rotating shaft along the radial direction of the rotating shaft; the push rod and the matching hole are spirally matched; the push rod and the matching hole are slidingly matched; a sliding protrusion is provided on the side wall of the push rod; a spiral groove is provided on the hole wall of the matching hole; the sliding protrusion and the spiral groove are slidingly matched to achieve spiral matching between the push rod and the matching hole; a compression spring is connected between the push rod and the matching hole; the inner ring is sleeved on the rotating shaft, and is slidingly matched with the end of the push rod away from the rotating shaft along the radial direction of the rotating shaft.
[0016] The outer ring is coaxially sleeved on the outside of the inner ring and rotates in conjunction with the inner ring; a matching groove is provided on the inner side wall of the outer ring; the matching groove is arranged along the circumference of the outer ring, with one end of the matching groove away from the axis of the outer ring and the other end close to the axis of the outer ring; the end of the push rod away from the axis of the rotating shaft slides in conjunction with the matching groove; initially, the compression spring causes the push rod to be located at the end of the matching groove away from the axis of the outer ring. When the material on the distribution plate is unevenly distributed and the rotational resistance to the outer ring increases, the resistance drives the outer ring to rotate relative to the inner ring, and the push rod slides from the end of the matching groove away from the axis of the outer ring to the end of the matching groove close to the axis of the outer ring. During this process, the push rod overcomes the elastic force of the compression spring and slides toward the axis of the rotating shaft in the matching hole. Under the cooperation of the sliding protrusion and the spiral groove, the push rod rotates around its own axis, causing the inner ring to drive the outer ring to deflect around the axis of the push rod, thereby moving thicker materials and spreading the materials, ensuring the uniformity of the material thickness.
[0017] Furthermore, a dispersion plate is provided within the fourth chamber; the dispersion plate extends forward and backward; one end of the dispersion plate is fixedly connected to the upper end of the vertical baffle, and the other end is fixedly connected to the housing; the end of the dispersion plate closest to the vertical baffle is higher than the end farther from the vertical baffle; the dispersion plate is provided with multiple dispersion holes, and the diameter of the dispersion holes gradually increases from the end closest to the vertical baffle to the end farther from the vertical baffle. This ensures that after entering the fourth chamber, the material first falls onto the dispersion plate, and then is dispersed by the dispersion holes of different diameters on the dispersion plate, making the material more evenly distributed on the distribution plate.
[0018] Furthermore, the widths of the first cavity and the third cavity gradually decrease from the feed port to the discharge port; and the widths of the second cavity and the fourth cavity gradually increase from the feed port to the discharge port.
[0019] Furthermore, the front end of the distribution plate is higher than the rear end; the upper end surface of the front end of the distribution plate is in a V shape with the small end facing upward.
[0020] The beneficial effects of the present invention are as follows: by setting the wind speed of the hot air in the third chamber to be greater than the wind speed of the hot air in the fourth chamber, the separation of powdered materials and agglomerated materials is achieved, and under the action of the vibration component, the agglomerates collide and disperse on the wavy part of the distribution plate, so that the agglomerates are gradually reduced, thereby making the material evenly distributed on the distribution plate, ensuring the effect of fluidization of the material, and being conducive to improving the uniformity of material drying.
[0021] Furthermore, when the material on the distribution plate is unevenly distributed and the rotational resistance of the outer ring increases, the resistance drives the outer ring to rotate relative to the inner ring, and the push rod slides from the end of the matching groove away from the axis of the outer ring to the end of the matching groove close to the axis of the outer ring. During this process, the push rod overcomes the elastic force of the compression spring and slides toward the axis of the rotating shaft in the matching hole. With the cooperation of the sliding protrusion and the spiral groove, the push rod rotates around its own axis, so that the inner ring drives the outer wheel to deflect around the axis of the push rod, so as to move the thicker material and spread the material, thereby ensuring the uniformity of the material thickness.
[0022] Furthermore, after entering the fourth chamber, the material first falls onto the dispersing plate, and is dispersed through the dispersing holes of different diameters on the dispersing plate, so that the material is more evenly distributed on the dispersing plate.

DETAILED DESCRIPTION

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.
[0039] An embodiment of a cobalt hydroxide drying and calcining device of the present invention is as follows Figures 1 to 13 As shown, a cobalt hydroxide drying and calcining device includes a base 100, a vertical partition 300, a guide plate 400, a vertical baffle 500, and an air supply component.
[0040] A housing 110 is provided above the base 100 so as to move up and down. A vibration spring is connected between the housing 110 and the base 100. The housing 110 is arranged front to back, with a feed port 111 provided at the front end and a discharge port 112 provided at the rear end. An exhaust port 113 is provided at the upper end of the housing 110. The exhaust port 113 is connected to a cyclone separator or a bag dust collector to collect the discharged fine particulate matter. A vibration assembly is provided on the housing 110. The vibration assembly includes a vibration motor. The vibration motor is fixed to the housing 110. A vertical partition 300 is provided within the housing 110. The vertical partition 300 extends forward and backward and is fixed to the bottom wall of the housing 110. A distribution plate 200 is fixed to the upper end of the vertical partition 300. The distribution plate 200 is provided with a plurality of through holes. The distribution plate 200 is fixedly connected to the inner wall of the housing 110.
[0041] The guide plate 400 is arranged above the distribution plate 200; the guide plate 400 is fixed on the inner wall of the shell 110; the guide plate 400 extends forward and backward; the guide plate 400 is a V-shaped plate with the small end facing upward; the guide plate 400 and the distribution plate 200 divide the shell 110 into an upper cavity, a middle cavity, and a lower cavity.
[0042] The vertical baffle 500 is arranged between the guide plate 400 and the distribution plate 200; the length of the vertical baffle 500 extends forward and backward, and the lower end of the vertical baffle 500 is fixed on the distribution plate 200; the vertical baffle 500 corresponds to the vertical partition 300 up and down; a separation gap 250 is provided between the upper end of the vertical baffle 500 and the guide plate 400; the vertical partition 300 divides the lower cavity into a first cavity and a second cavity; the vertical baffle 500 divides the middle cavity into a third cavity 230 and a fourth cavity 240; a plurality of air holes are provided on the part of the guide plate 400 corresponding to the third cavity 230; a blanking port 410 is provided at the front end of the third cavity 230; the blanking port 410 is opened on the guide plate 400; the blanking port 410 is connected to the feed port 111.
[0043] The third chamber 230 is connected to the upper chamber; the first and third chambers 230 are connected, and the second and fourth chambers 240 are connected; the third and fourth chambers 230 and 240 are connected via a separation gap 250. The portion of the distribution plate 200 within the third chamber 230 is wavy. The widths of the first and third chambers 230 gradually decrease from the feed inlet 111 to the discharge outlet 112, while the widths of the second and fourth chambers 240 gradually increase from the feed inlet 111 to the discharge outlet 112. The front end of the distribution plate 200 is higher than the rear end; the upper end surface of the front end of the distribution plate 200 is V-shaped, with the smaller end facing upward. After entering the third chamber 230, the material is driven by vibration and moves away from the vertical baffle 500. To ensure smooth entry of the material into the third chamber 230, the portion of the distribution plate 200 corresponding to the dropout 410 is not provided with a through hole. After the material falls, it is moved toward the discharge outlet 112 by vibration to the portion of the distribution plate 200 with the through hole.
[0044] The air supply component is used to supply heat and air to the first cavity and the second cavity, and make the wind speed of the hot air in the third cavity 230 greater than the wind speed of the hot air in the fourth cavity 240; the air supply component includes a first fan 610 and a second fan 620; the air outlet of the first fan 610 is connected to the first cavity through a first air duct, and the air outlet of the second fan 620 is connected to the second cavity through a second air duct; electric heating wires are provided in the first air duct and the second air duct to heat the air.
[0045] After the material enters the third chamber 230, the powdered material is blown upward by the hot air in the third chamber 230 and flows along the guide plate 400 through the separation gap 250 to the fourth chamber 240. Because the wind speed of the hot air in the third chamber 230 is greater than that in the fourth chamber 240, the powdered material falls to the portion of the distribution plate 200 in the fourth chamber 240 under the action of gravity. It then flows toward the discharge port 112 along with the vibration of the hot air. Agglomerated material trapped on the wavy portion of the distribution plate 200 collides with the wavy portion of the distribution plate 200 under the action of the vibration assembly, and the lumps collide with each other, which helps to disperse the lumps into powder. After the agglomerated material is dispersed back into powder, it continues to flow with the hot air in the third chamber 230 toward the guide plate 400 above. After being guided by the guide plate 400, it flows through the separation gap 250 into the fourth chamber 240 for fluidized drying. That is, by setting the wind speed of the hot air in the third chamber 230 to be greater than the wind speed of the hot air in the fourth chamber 240, the powdered material and the agglomerated material are separated. Under the action of the vibrating assembly, the agglomerates collide and disperse on the wavy portion of the distribution plate 200, gradually reducing the agglomerates. This allows the material to be evenly distributed on the distribution plate 200, ensuring the fluidization effect of the material and facilitating the uniformity of material drying. A dispersion plate 510 is provided in the fourth chamber 240. The dispersion plate 510 is arranged to extend forward and backward. One end of the dispersion plate 510 is fixedly connected to the upper end of the vertical baffle 500, and the other end is fixedly connected to the housing 110. The end of the dispersion plate 510 near the vertical baffle 500 is higher than the end away from the vertical baffle 500. The dispersion plate 510 is provided with a plurality of dispersion holes, and the diameter of the dispersion holes gradually increases from the end near the vertical baffle 500 to the end away from the vertical baffle 500. After entering the fourth chamber 240 , the material first falls onto the dispersing plate 510 , and is dispersed through the dispersing holes of different diameters on the dispersing plate 510 , so that the material is more evenly distributed on the distributing plate 200 .
[0046] A crushing assembly is also provided in the third chamber 230; the crushing assembly is used to crush the agglomerated material on the portion of the distribution plate 200 in the third chamber 230. There are multiple crushing assemblies distributed along the front-to-back direction. The crushing assembly includes a rotating shaft 710; the rotating shaft 710 is provided in the third chamber 230, and its two ends are rotatably mounted on the housing 110; the rotating shaft 710 is driven to rotate by a power structure; a plurality of straight pressure wheels 720 are coaxially fixed on the rotating shaft 710; an inclined pressure wheel 730 is provided between two adjacent straight pressure wheels 720; an angle is provided between the axis of the inclined pressure wheel 730 and the axis of the rotating shaft 710, so that the inclined pressure wheel 730 and the straight pressure wheel 720 are V-shaped. The agglomerates are located between the inclined pressure wheels 730 and the straight pressure wheels 720, and when the rotating shaft 710 rotates, the inclined pressure wheels 730 rotate and push the agglomerates toward the straight pressure wheels 720 and squeeze them, causing the agglomerates to break and disperse.
[0047] The power structure includes a pulley and a synchronous belt. The pulley is fixed to the end of the rotating shaft 710. The synchronous belt is mounted on the pulleys on the rotating shaft 710 of the multiple crushing components. The synchronous belt and pulleys are meshed. An auxiliary structure is located within the fourth chamber 240. This auxiliary structure is used to move the material on the distribution plate 200 within the fourth chamber 240 when the material thickness is uneven, ensuring uniform distribution.
[0048] The auxiliary structure is arranged in the fourth cavity 240 and above the distribution plate 200, including a push rod 740, an inner ring 750, and an outer ring 760; the axis of the push rod 740 is arranged radially along the rotating shaft 710; the rotating shaft 710 is provided with a matching hole arranged radially along the rotating shaft 710; the push rod 740 and the matching hole are spirally matched; specifically, the push rod 740 and the matching hole are slidingly matched; a sliding protrusion is provided on the side wall of the push rod 740; a spiral groove is provided on the hole wall of the matching hole; the sliding protrusion and the spiral groove are slidingly matched to achieve spiral matching between the push rod 740 and the matching hole; a compression spring is connected between the push rod 740 and the matching hole; the inner ring 750 is sleeved on the rotating shaft 710, and is radially slidingly matched with the end of the push rod 740 away from the rotating shaft 710 along the rotating shaft 710. The outer ring 760 is coaxially sleeved on the outside of the inner ring 750 and rotates in cooperation with the inner ring 750; a matching groove 770 is provided on the inner side wall of the outer ring 760; the matching groove 770 is arranged along the circumference of the outer ring 760, and one end of the matching groove 770 is away from the axis of the outer ring 760, and the other end is close to the axis of the outer ring 760; the end of the push rod 740 away from the axis of the rotating shaft 710 is slidably matched with the matching groove 770; initially, the compression spring causes the push rod 740 to be at the end of the matching groove 770 away from the axis of the outer ring 760.
[0049] When the material on the distribution plate 200 is unevenly distributed and the rotational resistance of the outer ring 760 increases, the resistance drives the outer ring 760 to rotate relative to the inner ring 750, and the push rod 740 slides from the end of the matching groove 770 away from the axis of the outer ring 760 to the end of the matching groove 770 close to the axis of the outer ring 760. During this process, the push rod 740 overcomes the elastic force of the compression spring and slides toward the axis of the rotating shaft 710 in the matching hole. With the cooperation of the sliding protrusion and the spiral groove, the push rod 740 rotates around its own axis, so that the inner ring 750 drives the outer ring 760 to deflect around the axis of the push rod 740, so as to move the thicker material and spread the material, thereby ensuring the uniformity of the material thickness.
[0050] In conjunction with the above embodiments, the operating principle and process of the present invention are as follows: After the material enters the third chamber 230, the powdered material is blown upward by the hot air in the third chamber 230 and flows along the guide plate 400 through the separation gap 250 to the fourth chamber 240. Because the wind speed of the hot air in the third chamber 230 is greater than the wind speed of the hot air in the fourth chamber 240, the powdered material falls to the portion of the distribution plate 200 in the fourth chamber 240 under the action of gravity. Following the vibration of the hot air, the powdered material flows toward the discharge port 112. Agglomerated material retained on the wavy portion of the distribution plate 200 collides with the wavy portion of the distribution plate 200 under the action of the vibration assembly, and the lumps collide with each other, which helps to disperse the lumps into powder. After the agglomerated material is dispersed into powder, it continues to flow with the hot air in the third chamber 230 toward the guide plate 400 above. After being guided by the guide plate 400, it flows through the separation gap 250 into the fourth chamber 240 for fluidized drying.
[0051] Specifically, by setting the hot air velocity in the third chamber 230 to be greater than that in the fourth chamber 240, the powdered material is separated from the agglomerated material. Under the action of the vibrating assembly, agglomerates collide and disperse on the wavy portion of the distribution plate 200, gradually reducing the agglomerates. This results in a uniform distribution of the material on the distribution plate 200, ensuring fluidization of the material and promoting uniform drying. The diameter of the dispersion holes gradually increases from the end closest to the vertical baffle 500 to the end farther from the vertical baffle 500. This ensures that after entering the fourth chamber 240, the material first falls onto the dispersion plate 510. After being dispersed by the dispersion holes of different diameters on the dispersion plate 510, the material is more evenly distributed on the distribution plate 200. Agglomerates are trapped between the inclined pressure wheel 730 and the direct pressure wheel 720. When the rotating shaft 710 rotates, the inclined pressure wheel 730 rotates, pushing the agglomerates toward the direct pressure wheel 720 and squeezing them, causing them to break up and disperse.
[0052] When the material on the distribution plate 200 is unevenly distributed and the rotational resistance of the outer ring 760 increases, the resistance drives the outer ring 760 to rotate relative to the inner ring 750, and the push rod 740 slides from the end of the matching groove 770 away from the axis of the outer ring 760 to the end of the matching groove 770 close to the axis of the outer ring 760. During this process, the push rod 740 overcomes the elastic force of the compression spring and slides toward the axis of the rotating shaft 710 in the matching hole. With the cooperation of the sliding protrusion and the spiral groove, the push rod 740 rotates around its own axis, so that the inner ring 750 drives the outer ring 760 to deflect around the axis of the push rod 740, so as to move the thicker material and spread the material, thereby ensuring the uniformity of the material thickness.
[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
