Description

Technical Field

[0001] The present invention relates to the technical field of drying, and particularly to a cobalt hydroxide drying and calcining device. Background Art

[0002] A vibrating fluidized bed dryer is an efficient drying device that combines vibration technology and fluidized bed principle, and is widely used in multiple industries. When drying cobalt hydroxide, a vibrating fluidized bed dryer is generally selected.

[0003] In the prior art, a vibrating fluidized bed dryer is based on the efficient combination of vibration drive and fluidization technology. The vibrating fluidized bed dryer includes a machine shell; a distribution plate is installed inside the machine shell. A plurality of ventilation holes are distributed on the distribution plate. Vibration is provided by a vibration motor, and hot air is injected below the distribution plate, so that the materials piled up on the distribution plate present a liquid-like state under the dual action of vibration and air flow, the particles tumble and mix violently, and under the drive of vibration, the powdery materials move from the feed port to the discharge port on the distribution plate.

[0004] However, during the drying process of the powdery materials, they agglomerate and form lumps due to surface moisture or electrostatic action. The existence of lumps may cause the ventilation holes on the distribution plate to be blocked, hinder the upward flow of gas, affect the fluidization effect on the materials, make the thickness of the materials distributed on the distribution plate uneven, affect the uniformity of material drying, and thus affect the consistency of subsequent material calcination. Summary of the Invention

[0005] The present invention provides a cobalt hydroxide drying and calcining device to solve the above problems.

[0006] A cobalt hydroxide drying and calcining device of the present invention adopts the following technical scheme: A cobalt hydroxide drying and calcining device includes a base, a vertical partition board, a guide plate, a vertical baffle, and a air supply assembly.

[0007] An outer shell is arranged above the base to move up and down; a vibration spring is connected between the outer shell and the base; the outer shell is arranged front and back, a feed port is arranged at the front end, and a discharge port is arranged at the rear end; an air exhaust port is arranged at the upper end of the outer shell; a vibration assembly is arranged on the outer shell.

[0008] The vertical partition board is arranged inside the outer shell; the length of the vertical partition board extends front and back, and it is fixed on the bottom wall of the outer shell; a distribution plate is fixed at the upper end of the vertical partition board; a plurality of through holes are arranged on the distribution plate; the distribution plate is fixedly connected to the inner wall of the outer shell.

[0009] The guide plate is arranged above the distribution plate; the guide plate is fixed on the inner wall of the outer shell; the length of the guide plate extends front and back; the guide plate is a V-shaped plate with the small end facing up; the guide plate and the distribution plate divide the outer shell into an upper cavity, a middle cavity, and a lower cavity.

[0010] The vertical baffle is arranged between the guide plate and the distribution plate; the length of the vertical baffle extends forward and backward, and the lower end of the vertical baffle is fixed on the distribution plate; the vertical baffle and the vertical partition correspond to each other up and down; a separation gap is provided between the upper end of the vertical baffle and the guide plate; the vertical partition divides the lower cavity into the first cavity and the second cavity; the vertical baffle divides the middle cavity into the third cavity and the fourth cavity; a plurality of air holes are provided on the part of the guide plate corresponding to the third cavity; a blanking port is provided at the front end of the third cavity; the blanking port is opened on the guide plate; the blanking port is connected with the feed port; the third cavity is connected with the upper cavity; the first cavity is connected with the third cavity, and the second cavity is connected with the fourth cavity; the third cavity and the fourth cavity are connected through the separation gap; the part of the distribution plate in the third cavity is wavy.

[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, a crushing assembly is provided in the third cavity; the crushing assembly is used to crush the agglomerated materials on the portion of the distribution plate located in the third cavity.

[0013] 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.

[0014] 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.

[0015] Furthermore, an auxiliary structure is provided in the fourth chamber; the auxiliary structure is used to stir the material when the thickness of the material distribution on the distribution plate in the fourth chamber is uneven, so as to promote the uniform distribution of the material.

[0016] Furthermore, the auxiliary structure is arranged in the fourth chamber and above the distribution plate, and includes a top rod, an inner ring and an outer ring; the axis of the top rod is arranged radially along the rotating shaft; a matching hole arranged radially along the rotating shaft is provided on the rotating shaft; the top rod and the matching hole are in screw fit; the top rod and the matching hole are in sliding fit; sliding protrusions are provided on the side wall of the top rod; spiral grooves are provided on the hole wall of the matching hole; the sliding protrusions and the spiral grooves are in sliding fit to realize the screw fit between the top rod and the matching hole; a compression spring is connected between the top rod and the matching hole; the inner ring is sleeved on the rotating shaft and is in radial sliding fit with the end of the top rod away from the rotating shaft.

[0017] The outer ring is coaxially sleeved outside the inner ring and is in rotational fit with the inner ring; a matching groove is provided on the inner side wall of the outer ring; the matching groove is arranged circumferentially along the outer ring, and one end of the matching groove is far from the axis of the outer ring and the other end is close to the axis of the outer ring; the end of the top rod away from the axis of the rotating shaft is in sliding fit with the matching groove; initially, the compression spring makes the top rod located at the end of the matching groove far from the axis of the outer ring. When the material distribution on the distribution plate is uneven, which increases the rotational resistance received by the outer ring, the resistance drives the outer ring to rotate relative to the inner ring, and the top rod slides from the end of the matching groove far 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 top rod overcomes the elastic force of the compression spring and slides towards the axis of the rotating shaft in the matching hole, and under the cooperation of the sliding protrusions and the spiral grooves, the top rod rotates around its own axis, so that the inner ring drives the outer ring to deflect around the axis of the top rod to stir the thicker material and spread out the material, ensuring the uniformity of the material thickness.

[0018] Furthermore, a dispersion plate is provided in the fourth chamber; the length of the dispersion plate extends in the front-back direction; one end of the dispersion plate is fixedly connected to the upper end of the vertical baffle plate, and the other end is fixedly connected to the housing; the end of the dispersion plate close to the vertical baffle plate is higher than the end far from the vertical baffle plate; a plurality of dispersion holes are provided on the dispersion plate, and the diameters of the dispersion holes gradually increase from the end close to the vertical baffle plate to the end far from the vertical baffle plate. So that the material falls onto the dispersion plate first after entering the fourth chamber, and after being dispersed by the dispersion holes with different diameters on the dispersion plate, the material is more evenly distributed on the distribution plate.

[0019] Furthermore, the widths of the first chamber and the third chamber gradually decrease from the feed port to the discharge port; the widths of the second chamber and the fourth chamber gradually increase from the feed port to the discharge port.

[0020] Further, the vibration assembly includes a vibration motor; the vibration motor is fixed on the housing; the air supply assembly includes a first blower and a second blower; the air outlet of the first blower and the first chamber are connected through a first air duct, and the air outlet of the second blower and the second chamber are connected through a second air duct; heating wires are provided in both the first air duct and the second air duct to heat the air.

[0021] Further, the front end of the distribution plate is higher than the rear end; the upper surface of the front end of the distribution plate is V-shaped with the small end facing upward.

[0022] The beneficial effects of the present invention are: 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 powdery materials and caked materials is achieved, and under the action of the vibration assembly, the caked materials collide and disperse on the wavy part of the distribution plate, so that the caked materials gradually decrease, thereby making the materials evenly distributed on the distribution plate, ensuring the effect of fluidizing the materials, and being beneficial to improving the uniformity of material drying.

[0023] Further, when the materials on the distribution plate are unevenly distributed, resulting in an increase in the rotational resistance received by the outer ring, the resistance drives the outer ring to rotate relative to the inner ring, and the ejector rod slides from the end of the mating groove away from the axis of the outer ring to the end of the mating groove close to the axis of the outer ring. During this process, the ejector rod overcomes the elastic force of the compression spring and slides towards the axis of the rotating shaft in the mating hole, and under the cooperation of the sliding convex and the spiral groove, the ejector rod rotates around its own axis, causing the inner ring to drive the outer ring to deflect around the axis of the ejector rod to stir the thicker materials and spread out the materials, ensuring the uniformity of the material thickness.

[0024] Further, after the materials enter the fourth chamber, they first fall onto the dispersion plate, and after being dispersed through the dispersion holes with different diameters on the dispersion plate, the materials are more evenly distributed on the distribution plate.

[0032] The vertical baffle 500 is arranged between the guide plate 400 and the distribution plate 200; the vertical baffle 500 extends longitudinally front and back, and the lower end of the vertical baffle 500 is fixed to the distribution plate 200; the vertical baffle 500 and the vertical partition 300 are vertically corresponding; 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 communicated with the feed inlet 111.

[0033] The third chamber 230 communicates with the upper chamber; the first chamber communicates with the third chamber 230, and the second chamber communicates with the fourth chamber 240; the third chamber 230 and the fourth chamber 240 communicate through a separation gap 250; the portion of the distribution plate 200 within the third chamber 230 is wavy; the widths of the first chamber and the third chamber 230 gradually decrease in the direction from the feed inlet 111 to the discharge outlet 112; the widths of the second chamber and the fourth chamber 240 gradually increase in the direction 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 small end facing upward. After the material enters the third chamber 230, it is driven by vibration to move away from the vertical baffle 500. To enable the material to smoothly enter the third chamber 230, no through holes are provided in the portion of the distribution plate 200 corresponding to the material dropping port 410. After the material drops, it moves toward the discharge outlet 112 by vibration to the portion of the distribution plate 200 where through holes are provided.

[0034] The air supply assembly is used to supply heat and air to the first chamber and the second chamber, and to make the wind speed of the hot air in the third chamber 230 greater than the wind speed of the hot air in the fourth chamber 240; the air supply assembly includes a first blower 610 and a second blower 620; the air outlet of the first blower 610 communicates with the first chamber through a first air duct, and the air outlet of the second blower 620 communicates with the second chamber through a second air duct; electric heating wires are provided in both the first air duct and the second air duct to heat the air.

[0035] After the material enters the third chamber 230, the powdery material in the material is blown upward by the hot air in the third chamber 230 and flows through the separation gap 250 along the guide plate 400 to the fourth chamber 240. Since the wind speed of the hot air in the third chamber 230 is greater than that of the hot air in the fourth chamber 240, the powdery material falls onto the part of the distribution plate 200 in the fourth chamber 240 under the action of gravity and flows towards the discharge port 112 with the cooperation of the hot air and vibration; the caked material retained on the wavy part of the distribution plate 200 collides with the wavy part of the distribution plate 200 under the action of the vibration assembly, and the caked materials collide with each other, which is conducive to the caked materials spreading out into a powdery state. After the caked materials are redispersed into powdery materials, they continue to flow upward along the guide plate 400 with the hot air in the third chamber 230, and after being guided by the guide plate 400, they flow into the fourth chamber 240 through the separation gap 250 for fluidized drying. That is, by setting the wind speed of the hot air in the third chamber 230 to be greater than that of the hot air in the fourth chamber 240, the separation of the powdery material and the caked material is realized, and under the action of the vibration assembly, the caked materials collide and disperse on the wavy part of the distribution plate 200, so that the caked materials gradually decrease, thereby making the material evenly distributed on the distribution plate 200, ensuring the effect of fluidizing the material, and being beneficial to improving the uniformity of material drying. A dispersion plate 510 is provided in the fourth chamber 240; the length of the dispersion plate 510 extends in the front-rear direction; 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 outer shell 110; the end of the dispersion plate 510 close to the vertical baffle 500 is higher than the end far from the vertical baffle 500; a plurality of dispersion holes are provided on the dispersion plate 510, and the diameters of the dispersion holes gradually increase from the end close to the vertical baffle 500 to the end far from the vertical baffle 500. So that after the material enters the fourth chamber 240, it first falls onto the dispersion plate 510, and after being dispersed by the dispersion holes with different diameters on the dispersion plate 510, the material is more evenly distributed on the distribution plate 200.

[0036] A crushing assembly is further provided in the third chamber 230; the crushing assembly is used for crushing the caked material on the part of the distribution plate 200 in the third chamber 230. A plurality of the crushing assemblies are distributed in the front-rear direction. The crushing assembly includes a rotating shaft 710; the rotating shaft 710 is arranged in the third chamber 230, and both ends are rotatably installed on the outer shell 110; the rotating shaft 710 is driven to rotate by a power structure; a plurality of straight pressing wheels 720 are coaxially fixed on the rotating shaft 710; an inclined pressing wheel 730 is provided between two adjacent straight pressing wheels 720; an included angle is provided between the axis of the inclined pressing wheel 730 and the axis of the rotating shaft 710, so that the inclined pressing wheel 730 and the straight pressing wheels 720 are in a V shape. The caked material is between the inclined pressing wheel 730 and the straight pressing wheels 720, and when the rotating shaft 710 rotates, the inclined pressing wheel 730 rotates to push the caked material towards the straight pressing wheels 720 and squeeze it, so as to promote the caked material to break and disperse.

[0037] 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 sleeved on the pulleys on the rotating shafts 710 of multiple crushing components; the synchronous belt meshes with the pulley. An auxiliary structure is provided in the fourth chamber 240; the auxiliary structure is used to stir the material when the thickness of the material distribution on the distribution plate 200 in the fourth chamber 240 is uneven, so as to promote the uniform distribution of the material.

[0038] The auxiliary structure is provided in the fourth chamber 240 and is located above the distribution plate 200, and includes a top rod 740, an inner ring 750, and an outer ring 760; the axis of the top rod 740 is arranged along the radial direction of the rotating shaft 710; a matching hole is provided on the rotating shaft 710 along the radial direction of the rotating shaft 710; the top rod 740 and the matching hole are in screw fit; specifically, the top rod 740 and the matching hole are in sliding fit; a sliding convex is provided on the side wall of the top rod 740; a spiral groove is provided on the hole wall of the matching hole; the sliding convex and the spiral groove are in sliding fit to realize the screw fit between the top rod 740 and the matching hole; a compression spring is connected between the top rod 740 and the matching hole; the inner ring 750 is sleeved on the rotating shaft 710 and is in sliding fit with the end of the top rod 740 away from the rotating shaft 710 along the radial direction of the rotating shaft 710. The outer ring 760 is coaxially sleeved outside the inner ring 750 and is in rotational fit 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 circumferential direction of the outer ring 760, and one end of the matching groove 770 is far 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 top rod 740 away from the axis of the rotating shaft 710 is in sliding fit with the matching groove 770; initially, the compression spring makes the top rod 740 located at the end of the matching groove 770 far from the axis of the outer ring 760.

[0039] When the material distribution on the distribution plate 200 is uneven, resulting in an increase in the rotational resistance received by the outer ring 760, the resistance drives the outer ring 760 to rotate relative to the inner ring 750. The top rod 740 slides from the end of the matching groove 770 far 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 top rod 740 overcomes the elastic force of the compression spring and slides towards the axis of the rotating shaft 710 in the matching hole. And under the cooperation of the sliding convex and the spiral groove, the top rod 740 rotates around its own axis, causing the inner ring 750 to drive the outer ring 760 to deflect around the axis of the top rod 740, so as to stir the thicker material and spread out the material, ensuring the uniformity of the material thickness.

[0040] Combined with the above embodiments, the working principle and process of the present invention are as follows: After the material enters the third chamber 230, the powdery material in the material is blown upward by the hot air in the third chamber 230 and flows through the separation gap 250 along the guide plate 400 into the fourth chamber 240. Since the wind speed of the hot air in the third chamber 230 is greater than that of the hot air in the fourth chamber 240, the powdery material falls onto the part of the distribution plate 200 in the fourth chamber 240 under the action of gravity and flows toward the discharge port 112 along with the hot air and vibration; the caked material retained on the wavy part of the distribution plate 200 collides with the wavy part of the distribution plate 200 under the action of the vibration assembly, and the caked materials collide with each other, which is conducive to the caked materials spreading out into a powdery state. After the caked materials are redispersed into powdery materials, they continue to flow upward along the guide plate 400 with the hot air in the third chamber 230, and after being guided by the guide plate 400, they flow into the fourth chamber 240 through the separation gap 250 for fluidized drying.

[0041] That is, by setting the wind speed of the hot air in the third chamber 230 to be greater than that of the hot air in the fourth chamber 240, the separation of powdery materials and caked materials is achieved. And under the action of the vibration assembly, the caked materials collide and disperse on the wavy part of the distribution plate 200, so that the caked materials gradually decrease, thus enabling the materials to be evenly distributed on the distribution plate 200, ensuring the effect of fluidizing the materials, and being beneficial to improving the uniformity of material drying. The diameter of the dispersion holes gradually increases from the end close to the vertical baffle 500 to the end far from the vertical baffle 500. So that after the material enters the fourth chamber 240, it first falls onto the dispersion plate 510, and after being dispersed by the dispersion holes with different diameters on the dispersion plate 510, the materials are more evenly distributed on the distribution plate 200. The caked materials are located between the oblique pressing wheel 730 and the straight pressing wheel 720, and when the rotating shaft 710 rotates, the oblique pressing wheel 730 rotates to push the caked materials toward the straight pressing wheel 720 and squeeze them, prompting the caked materials to break and disperse.

[0042] When the distribution of the materials on the distribution plate 200 is uneven, resulting in an increase in the rotational resistance received by the outer ring 760, the resistance drives the outer ring 760 to rotate relative to the inner ring 750. The ejector rod 740 slides from the end of the mating groove 770 far from the axis of the outer ring 760 to the end of the mating groove 770 close to the axis of the outer ring 760. During this process, the ejector rod 740 overcomes the elastic force of the compression spring and slides toward the axis of the rotating shaft 710 in the mating hole. And under the cooperation of the sliding convex and the spiral groove, the ejector rod 740 rotates around its own axis, causing the inner ring 750 to drive the outer ring 760 to deflect around the axis of the ejector rod 740, so as to dial the thicker materials and spread out the materials, ensuring the uniformity of the material thickness.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
