Description

Technical Field

[0001] This invention relates to the field of potassium superoxide powder granulation technology, and in particular to a potassium superoxide powder granulation device. Background Technology

[0002] Potassium superoxide is a yellow powdery inorganic compound that can react with both carbon dioxide exhaled by the human body and water vapor to produce oxygen. Taking advantage of this property, it is often used in emergency rescue in coal mines, air regeneration in confined spaces, and as an oxygen source for breathing masks.

[0003] Potassium superoxide, as a chemical oxygen source, is usually mixed with auxiliary materials such as bentonite and calcium hydroxide and then pressed into shape. However, during the drying process, the uneven distribution of hot air in the equipment and insufficient turning of the particles result in a significant temperature difference between the inside and outside of the particles, which easily leads to cracking or even breakage. This causes a significant reduction in particle strength, which not only affects the product qualification rate but also poses safety hazards in subsequent storage, transportation and use. Summary of the Invention

[0004] This invention discloses a potassium superoxide powder granulation device, which aims to solve the technical problem that during the drying process of formed granules, the uneven distribution of hot air inside the device and insufficient granule agitation result in a significant temperature difference between the inside and outside of the granules, which easily leads to cracking or even breakage, causing a significant reduction in granule strength. This not only affects the product qualification rate but also brings safety hazards in subsequent storage, transportation and use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A potassium superoxide powder granulation device includes a granulator body and an outer cylinder. The granulator body is fixedly installed on the top of the outer cylinder and is connected to the feed inlet of the outer cylinder. A support is provided on the outer wall of the outer cylinder. The device also includes a turning mechanism disposed inside the outer cylinder for turning and drying potassium superoxide granules. The turning mechanism includes a connecting shaft and an inner cylinder. The inner cylinder is fixedly installed inside the outer cylinder. Multiple guide plates and multiple discharge holes are evenly distributed on the outer circumference of the inner cylinder. A first motor is fixedly installed on one side of the outer cylinder. The output shaft of the first motor is fixedly connected to one end of the connecting shaft. Two sets of stirring plates are provided on the outer circumference of the connecting shaft. A mounting plate is connected to the inner circumference of the inner cylinder near the feed inlet via a sealed bearing. The end of the connecting shaft away from the first motor is fixedly connected to the mounting plate. A scraper is fixedly installed on the outer edge of the stirring plate.

[0007] A drying mechanism is provided on the top outer wall of the outer cylinder for supplying hot air to the interior of the outer cylinder. The drying mechanism includes an air pump and a fixed box. A heating box is provided on one side of the outer wall of the fixed box. The air outlet of the air pump is connected to the interior of the heating box. A heating plate is provided inside the heating box. Air blowing assemblies are provided on both sides of the outer wall of the fixed box. The air blowing assemblies are connected to the interior of the outer cylinder.

[0008] Feeding assembly: Located below the outer cylinder, used to discharge the dried granules;

[0009] Lifting component: electrically connected to the drying mechanism.

[0010] The above technical solution effectively eliminates the temperature difference problem caused by the bottom overheating and the top underheating of the granules due to static stacking, ensuring the uniformity of granule heating and preventing cracking or substandard moisture content caused by uneven drying time. Specifically, the air pump heats the outside air through the heating plate and sends it into the fixed box. The trumpet-shaped guide plate smoothly guides the hot air into the fixed box and delivers it to the inner cylinder through the air blowing components on both sides to heat and dry the potassium superoxide granules. During this process, the first motor drives the connecting shaft to rotate, and the connecting shaft drives the stirring plate to rotate synchronously. The spiral structure of the stirring plate generates axial thrust on the granules. The two sets of stirring plates with opposite spiral directions make the granules form a wave-like reciprocating motion trajectory in the cylinder. During the movement, the granules are continuously lifted, scattered, and rolled, constantly changing the contact surface with the hot air, so that the hot air can penetrate the interior of the granule layer for all-round heating, effectively preventing cracking and breakage caused by uneven heating, and greatly improving the granule strength and product qualification rate.

[0011] In a preferred embodiment, the stirring plate has a spiral structure, and the spiral directions of the two sets of stirring plates are opposite. The stirring plate has multiple connecting holes along its spiral surface, which are used to allow hot airflow inside the inner cylinder to pass through.

[0012] In this scheme, the particles reciprocate between forward and reverse spirals, constantly changing their direction and speed, which avoids excessive accumulation of particles at the discharge end and ensures the uniformity and continuity of material flow. At the same time, the connecting holes allow the hot airflow to penetrate the mixing plate and reach different depths of the particle layer. Even particles inside the particle layer can be dried with hot air, fundamentally eliminating the drying dead zone and uneven heating.

[0013] In a preferred embodiment, the air blowing assembly includes an air collecting box, a plurality of first branch pipes, and a plurality of second branch pipes. The air collecting box is installed on the outer wall of the outer cylinder and communicates with the interior of the outer cylinder. One end of the first branch pipe is connected to the mounting pipe, and the other end of the first branch pipe is connected to the air collecting box. One end of the second branch pipe is connected to the air collecting box, and the other end of the second branch pipe is connected to the first branch pipe. The air collecting box has a plurality of air nozzles on the side facing the interior of the outer cylinder.

[0014] In this design, the first and second branch pipes form a closed loop between the gas collection box and the installation pipe, ensuring that the gas in the pipeline is always in a flowing state. This effectively balances the air pressure in different areas inside the gas collection box, making the air outlet speed and air volume of each nozzle distributed along the length of the gas collection box basically the same. At the same time, the two wings of the "V"-shaped gas collection box face the planes on both sides of the corner of the regular hexagonal outer cylinder, and the hot air blown out by the nozzles flows close to the inner wall of the outer cylinder, effectively avoiding the airflow turbulence caused by the hot air blowing directly towards the center area of ​​the outer cylinder. It can also blow the particles attached to the inner wall of the outer cylinder away from the wall surface, reducing the residence and adhesion of particles on the wall surface.

[0015] In a preferred embodiment, the lifting assembly is located on the top outer wall of the heating box. The lifting assembly includes a mounting frame, and the top outer wall of the mounting frame is provided with an electric telescopic rod. The movable end of the electric telescopic rod is fixedly connected to the heating plate. An adapter slot is provided inside the heating box, and the heating plate is slidably connected in the adapter slot.

[0016] In this solution, when the temperature sensor detects that the hot air temperature exceeds the set value, the electric telescopic rod actively drives the heating plate to slide along the adapter groove according to the electrical signal of the temperature sensor, changing the position of the heating wire relative to the airflow channel. When the heating wire is close to the airflow channel, the air is heated to a higher temperature; when the heating wire is away from the airflow channel, the air temperature decreases. This allows for real-time correction of temperature deviations, ensuring that the hot air temperature remains stable within the set range. The length of the adapter groove limits the maximum sliding stroke of the heating plate, preventing the heating plate from detaching from the adapter groove or impacting the inner wall of the heating chamber due to over-driving of the electric telescopic rod, thus ensuring the safe operation of the equipment.

[0017] The beneficial effects of this invention are:

[0018] 1. This invention uses two sets of stirring plates with opposite spiral directions inside the inner cylinder to create a wave-like reciprocating motion trajectory for the particles during the drying process. The particles are continuously lifted, scattered, and tumbled, constantly changing the contact surface with the hot air. With the connection holes on the stirring plates, the hot airflow can penetrate the stirring plates to reach different depths of the particle layer, achieving all-round three-dimensional heating from the outside to the inside. Compared with the existing technology where the particles are relatively statically piled on the bearing surface and the hot air has difficulty penetrating the particle layer, this invention effectively prevents the particles from cracking and breaking due to uneven heating, and greatly improves the particle strength and product qualification rate.

[0019] 2. This invention utilizes the feeding holes opened on the inner cylinder wall to allow particles smaller than the feeding holes to be naturally discharged under their own gravity, while larger particles are blocked by the feeding holes and continue to be further dried inside the inner cylinder. This avoids the problem of fine particles being over-dried and coarse particles not being dried due to the same drying time for all particles in traditional devices, and ensures the uniformity of product moisture content.

[0020] 3. This invention uses an installation pipe to evenly distribute hot air to the air blowing components on both sides. Combined with the closed loop formed by the first and second branch pipes, it effectively balances the air pressure in different areas inside the air collection box, ensuring that the air outlet speed and air volume of each nozzle distributed along the length of the air collection box are basically the same. At the same time, the "V"-shaped air collection box and the edges of the regular hexagonal outer cylinder match, allowing the hot air to flow closely against the inner wall of the outer cylinder, effectively avoiding airflow turbulence and dead zones, ensuring the full coverage and uniformity of hot air distribution inside the outer cylinder, and providing a stable hot air environment for the uniform drying of particles.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11A potassium superoxide powder granulation device includes a granulator body 3 and an outer cylinder 1. The granulator body 3 is fixedly installed on the top of the outer cylinder 1 and is connected to the feed inlet of the outer cylinder 1. A support 2 is provided on the outer wall of the outer cylinder 1. The device also includes a turning mechanism, located inside the outer cylinder 1, for turning and drying the potassium superoxide granules. The turning mechanism includes a connecting shaft 35 and an inner cylinder 30, which is fixedly installed inside the outer cylinder 1. Multiple evenly spaced sections are provided on the outer circumferential wall of the inner cylinder 30. The cloth guide plate 18 has multiple equally spaced discharge holes 31. A first motor 7 is fixedly installed on one side of the outer wall of the outer cylinder 1. The output shaft of the first motor 7 is fixedly connected to one end of the connecting shaft 35. Two sets of stirring plates 33 are provided on the outer circumference of the connecting shaft 35. The inner circumference of the inner cylinder 30 near the feed inlet is connected to the mounting plate 22 through a sealed bearing. The end of the connecting shaft 35 away from the first motor 7 is fixedly connected to the mounting plate 22. A scraper 37 is fixedly installed on the outer edge of the stirring plate 33.

[0035] The drying mechanism is located on the top outer wall of the outer cylinder 1 and is used to supply hot air to the interior of the outer cylinder 1. The drying mechanism includes an air pump 8 and a fixed box 5. A heating box 21 is provided on one side of the outer wall of the fixed box 5. The air outlet of the air pump 8 is connected to the interior of the heating box 21. A heating plate 27 is provided inside the heating box 21. Air blowing components are provided on both sides of the outer wall of the fixed box 5 and are connected to the interior of the outer cylinder 1. The feeding component is located below the outer cylinder 1 and is used to discharge the dried particles. The lifting component is electrically connected to the drying mechanism.

[0036] The heating chamber 21 has an installation port on its outer wall near the air pump 8, and a filter screen 26 is installed at the installation port. Inside the heating chamber 21, there is also a temperature sensor 14 and a guide plate 28. The guide plate 28 is located on one side of the heating plate 27, which has four installation cavities. Each installation cavity has two installation rings 29, and a heating wire 36 is located between the two installation rings 29 in the same installation cavity. The guide plate 28 has a trumpet-shaped structure. When the air pump 8 draws in air from the outside, the air may contain dust, particulate matter, and other impurities. The filter screen 26 intercepts these impurities before they enter the heating chamber 21, preventing them from entering the drying area with the hot air. To avoid contaminating the potassium superoxide particles and ensure product purity, temperature sensor 14 monitors the hot air temperature inside the heating chamber 21 in real time. When temperature sensor 14 detects that the hot air temperature exceeds the set value, the lifting component drives the heating plate 27 to slide along the adapter groove, changing the position of the heating wire 36 relative to the airflow channel, thereby adjusting the hot air temperature. This prevents the potassium superoxide particles from becoming over-dry or even thermally decomposed due to excessive temperature, ensuring product quality and operational safety. In addition, the symmetry of the trumpet-shaped structure helps to evenly distribute the hot air to the air blowing components on both sides of the fixed chamber 5, avoiding uneven heating of the particles inside the outer cylinder 1 due to inconsistent airflow on both sides.

[0037] In the specific implementation process, the stirring plate 33 has a spiral structure, and the spiral directions of the two sets of stirring plates 33 are opposite. The stirring plate 33 has multiple connecting holes 34 along its spiral surface. The connecting holes 34 are used to allow the hot airflow inside the inner cylinder 30 to pass through. The particles reciprocate between the forward spiral and the reverse spiral, constantly changing the direction and speed of movement, avoiding excessive accumulation of particles at the discharge end, and ensuring the uniformity and continuity of material flow. At the same time, the connecting holes 34 allow the hot airflow to penetrate the stirring plate 33 to reach different depths of the particle layer. Even the particles inside the particle layer can be dried with hot air, fundamentally eliminating the drying dead zone and uneven heating phenomenon.

[0038] The fixed box 5 is equipped with an installation pipe 15, which has a "Y" shaped structure. The air inlet end of the installation pipe 15 is sealed to the guide plate 28. An exhaust box 16 is installed inside the fixed box 5. An exhaust hole 6 is opened on the top outer wall of the overlapping part of the fixed box 5 and the exhaust box 16. The "Y" shaped structure splits the hot air from the heating box 21 into two parts, which are respectively delivered to the air blowing components on both sides of the fixed box 5. The symmetrical "Y" shaped design ensures that the air volume flowing through the two branch pipes is basically the same, so that the hot air flow rate entering the outer cylinder 1 is balanced.

[0039] In the specific implementation process, a connecting port 32 is opened on the top outer wall of the outer cylinder 1. The outer cylinder 1 is connected to the exhaust box 16 through the connecting port 32. After the hot air enters the outer cylinder 1 to dry the potassium superoxide particles, it carries a large amount of water vapor and becomes humid and hot exhaust gas. If the humid and hot exhaust gas cannot be discharged in time, it will accumulate inside the outer cylinder 1, reducing the moisture carrying capacity of the hot air and potentially causing a decrease in drying efficiency. The connection port 32 and the exhaust box 16 provide a dedicated exhaust gas discharge channel, allowing the humid and hot exhaust gas to be discharged from the outer cylinder 1 in an orderly manner.

[0040] Specifically, the air pump 8 is started first, and the outside air is heated by the heating plate 27 in the heating box 21 and then sent into the fixed box 5. The guide plate 28 guides the heated hot air into the fixed box 5 and delivers it to the inside of the outer cylinder 1 through the air blowing components on both sides of the fixed box 5. The potassium superoxide particles in the outer cylinder 1 are heated and dried. At the same time, the gas is discharged through the connecting port 32 at the top of the outer cylinder 1 via the installation pipe 15 and the exhaust box 16, forming a circulating airflow.

[0041] Then, after the potassium superoxide granules are formed by the granulator body 3, they enter the inner cylinder 30 through the feed port at the top of the outer cylinder 1. Then, the first motor 7 is started, driving the connecting shaft 35 to rotate. The connecting shaft 35 drives the mounting plate 22 and the stirring plate 33 connected to it to rotate synchronously. The spiral structure of the stirring plate 33 generates an axial thrust on the potassium superoxide granules falling into the inner cylinder 30 during the rotation. Under the combined action of the two sets of opposite spirals, the granules form a wave-like reciprocating motion trajectory instead of moving in a straight line in one direction, thereby prolonging the residence time of the granules in the inner cylinder 30 and allowing them to be dried more thoroughly.

[0042] During the drying process, the particles reciprocate under the push of two sets of stirring plates 33. During the movement of the particles, particles with a diameter smaller than the feed hole 31 of the inner cylinder 30 pass through the feed hole 31 under their own gravity and fall to the bottom of the outer cylinder 1. Particles with a diameter larger than the feed hole 31 are blocked by the feed hole 31 and remain inside the inner cylinder 30, thus obtaining a longer drying time. The connecting holes 34 opened along the spiral surface of the stirring plates 33 allow hot air to pass through, so that the hot air can directly heat the particles around the stirring plates 33 and avoid the stirring plates 33 blocking the flow path of the hot air. The scraper 37 rotates synchronously with the connecting shaft 35. In specific implementation, the scraper 37 extends along the axial direction of the inner cylinder 30, and its length is not less than the internal length of the inner cylinder 30. During the rotation, it maintains a small gap with the inner wall of the inner cylinder 30, continuously scraping off the potassium superoxide particles adhering to the inner wall of the inner cylinder 30, preventing the accumulation of particles sticking to the wall. This device effectively eliminates the temperature difference problem caused by the bottom overheating and the top underheating of the particles due to static stacking, ensuring the uniformity of particle heating, and preventing the particles from cracking or failing to meet the moisture content standards due to uneven drying time.

[0043] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In a preferred embodiment, the air blowing assembly includes an air collecting box 24, a plurality of first branch pipes 9 and a plurality of second branch pipes 17. The air collecting box 24 is installed on the outer wall of the outer cylinder 1 and communicates with the interior of the outer cylinder 1. One end of the first branch pipe 9 is connected to the mounting pipe 15 and the other end of the first branch pipe 9 is connected to the air collecting box 24. One end of the second branch pipe 17 is connected to the air collecting box 24 and the other end of the second branch pipe 17 is connected to the first branch pipe 9. The air collecting box 24 is provided with a plurality of air nozzles 25 on the side facing the interior of the outer cylinder 1.

[0044] The outer cylinder 1 has a regular hexagonal structure, and the gas collection box 24 has a "V" shaped structure. Multiple connection ports are opened on both sides of the outer wall of the outer cylinder 1, and the gas collection box 24 is sealed and installed in the connection ports.

[0045] It is particularly important to note that two buffer plates 19 are provided above the bottom inner wall of the outer cylinder 1. Multiple sets of return springs 20 are provided between the buffer plates 19 and the bottom inner wall of the outer cylinder 1. When the potassium superoxide particles fall out of the discharge hole 31 of the inner cylinder 30, they have a certain height difference and falling speed. If the particles directly hit the hard wall surface at the bottom of the outer cylinder 1, the impact force may cause the particles to crack, break or even pulverize. The buffer plates 19 first catch the particles during the falling process, and use the elastic deformation of the springs to absorb the impact kinetic energy of the particles, slow down the falling speed of the particles, and allow the particles to slide smoothly from the surface of the buffer plates 19 to the bottom of the outer cylinder 1, effectively avoiding the particles from being damaged by hitting the hard wall.

[0046] It should be noted that the buffer plate 19 can be made of polytetrafluoroethylene coated metal plate. PTFE has excellent non-stick and chemical inertness, making it suitable for handling materials such as potassium superoxide that are easy to absorb moisture and adhere, and can effectively prevent particles from accumulating on the buffer plate 19.

[0047] Specifically, the first branch pipe 9 and the second branch pipe 17 form a closed loop between the gas collecting box 24 and the installation pipe 15, so that the gas in the pipeline is always in a flowing state, effectively balancing the air pressure in each area inside the gas collecting box 24, making the air outlet speed and air volume of each nozzle 25 distributed along the length of the gas collecting box 24 basically the same. At the same time, the two wings of the "V"-shaped gas collecting box 24 face the plane direction on both sides of the corner of the regular hexagonal outer cylinder 1, and the hot air blown out by the nozzle 25 flows closely against the inner wall of the outer cylinder 1, effectively avoiding the airflow turbulence caused by the hot air blowing directly towards the central area of ​​the outer cylinder 1. At the same time, it can blow the particles attached to the inner wall of the outer cylinder 1 away from the wall surface, reducing the residence and adhesion of particles on the wall surface.

[0048] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 In a preferred embodiment, the lifting assembly is located on the top outer wall of the heating box 21. The lifting assembly includes a mounting frame 10. The top outer wall of the mounting frame 10 is provided with an electric telescopic rod 11. The movable end of the electric telescopic rod 11 is fixedly connected to the heating plate 27. An adapter groove is provided inside the heating box 21, and the heating plate 27 is slidably connected in the adapter groove.

[0049] Specifically, when the temperature sensor 14 detects that the hot air temperature exceeds the set value, the electric telescopic rod 11 actively drives the heating plate 27 to slide along the adapter groove according to the electrical signal of the temperature sensor 14, changing the position of the heating wire 36 relative to the airflow channel. When the heating wire 36 is close to the airflow channel, the air is heated to a higher temperature. When the heating wire 36 is away from the airflow channel, the air temperature decreases, thereby correcting the temperature deviation in real time and ensuring that the hot air temperature is always stable within the set range. The length of the adapter groove limits the maximum sliding stroke of the heating plate 27, preventing the heating plate 27 from detaching from the adapter groove or hitting the inner wall of the heating box 21 due to over-driving of the electric telescopic rod 11, thus ensuring the safe operation of the equipment.

[0050] Compared to intermittent heating and temperature control, this solution has smaller hot air temperature fluctuations and more stable drying effect. Most existing drying devices use fixed heating plates 27, and the hot air temperature can only be changed by adjusting the power of the heating wire 36, which has a slow response speed and large adjustment lag. This solution achieves temperature regulation through physical displacement, which has a fast adjustment speed and high control accuracy.

[0051] Reference Figure 1 and Figure 2 In a preferred embodiment, the feeding assembly includes a second motor 13 and a conveying box 4. The bottom outer wall of the outer cylinder 1 has a feeding port located above the conveying box 4. The conveying box 4 is a semi-enclosed structure, and the bottom outer wall of the conveying box 4 has a discharge port. An auger 12 is rotatably connected inside the conveying box 4. The output shaft of the second motor 13 is fixedly connected to one end of the auger 12. After the dried particles fall into the conveying box 4 from the feeding port of the outer cylinder 1, the second motor 13 drives the auger 12 to rotate continuously, applying an axial thrust to the particles falling into the conveying box 4, forcibly pushing the particles towards the discharge port, ensuring that the particles are discharged in time.

[0052] Working principle: When in use, first start the air pump 8 to heat the outside air through the heating plate 27 in the heating box 21 and send it into the fixed box 5. The guide plate 28 guides the heated hot air into the fixed box 5 and delivers it to the inside of the outer cylinder 1 through the air blowing components on both sides of the fixed box 5. The potassium superoxide particles in the outer cylinder 1 are heated and dried. At the same time, the gas is discharged through the connecting port 32 at the top of the outer cylinder 1 via the installation pipe 15 and the exhaust box 16, forming a circulating airflow.

[0053] Then, after the potassium superoxide granules are formed by the granulator body 3, they enter the inner cylinder 30 through the feed port at the top of the outer cylinder 1. Then, the first motor 7 is started, driving the connecting shaft 35 to rotate. The connecting shaft 35 drives the mounting plate 22 and the stirring plate 33 connected to it to rotate synchronously. The spiral structure of the stirring plate 33 generates an axial thrust on the potassium superoxide granules falling into the inner cylinder 30 during the rotation. Under the combined action of the two sets of opposite spirals, the granules form a wave-like reciprocating motion trajectory instead of moving in a straight line in one direction, thereby prolonging the residence time of the granules in the inner cylinder 30 and allowing them to be dried more thoroughly.

[0054] During the drying process, the particles reciprocate under the push of two sets of stirring plates 33. During the movement of the particles, particles with a diameter smaller than the feed hole 31 of the inner cylinder 30 pass through the feed hole 31 under their own gravity and fall into the bottom of the outer cylinder 1. Particles with a diameter larger than the feed hole 31 are blocked by the feed hole 31 and remain inside the inner cylinder 30, thus obtaining a longer drying time. The connecting holes 34 opened along the spiral surface of the stirring plate 33 allow hot air to pass through, so that the hot air can directly heat the particles around the stirring plate 33 and avoid the stirring plate 33 blocking the flow path of the hot air. The scraper 37 rotates synchronously with the connecting shaft 35. During the rotation, it maintains a small gap with the inner wall of the inner cylinder 30 and continuously scrapes off the potassium superoxide particles adhering to the inner wall of the inner cylinder 30, preventing the particles from accumulating on the wall.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
