Description

Technical Field

[0001] This invention relates to the field of spray granulation technology, specifically to a vacuum spray granulator with gas-solid separation function. Background Technology

[0002] Spray fluidized bed granulators are suitable for granulating and drying various inorganic and organic solutions, suspensions, emulsions, and high-temperature melts, such as calcium chloride, zinc sulfate, ammonium chloride, magnesium chloride, and urea, in a single operation. They can be used continuously or intermittently. However, conventional vacuum spray granulators have some drawbacks in their use, such as:

[0003] Conventional vacuum spray granulators cannot separate gas from solids during operation. This results in solid particles containing a significant amount of gas, leading to higher gas pressure on the solid particle side. During contact between the solid particles and the sprayed gas, the gas on the solid particle side affects the contact between them. Furthermore, as the device is used, the moisture content within it becomes high. Conventional vacuum spray granulators cannot absorb water from the circulating gas. Because water dilutes the mixed particles, the final product contains less mixed particles, resulting in poor product quality. Summary of the Invention

[0004] The purpose of this invention is to provide a vacuum spray granulator with gas-solid separation function to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a vacuum spray granulator with gas-solid separation function, comprising a frame and a vacuum pump. The vacuum pump is installed at the upper end of the frame, and its side is connected to a separation chamber. A feeding mechanism is installed at the upper end of the separation chamber, and an air inlet pipe is installed at the tail end of the separation chamber. A fan is installed inside the separation chamber. A connecting pipe is installed at the lower left end of the separation chamber and is connected to the lower side of the frame. A conveying pipe is installed at the middle of the lower end of the separation chamber. A water storage mechanism is installed inside the lower left side of the separation chamber. The conveying pipe is connected to the upper side of the frame, and the side of the connecting pipe is connected to a heating mechanism. The heating mechanism is located inside the lower part of the frame, and an agglomeration unit is installed inside the upper part of the frame. The device has a spiral-shaped fixed channel inside the frame. When in use, the material is added to the separation chamber through the feeding mechanism, and external gas is introduced into the separation chamber through the air inlet pipe. The gas inside the frame is circulated by a vacuum pump. The gas then circulates between the separation chamber and the frame through the connecting pipe, while the material flows downward from the separation chamber to the frame through the conveying pipe. The gas is then heated by the heating mechanism, which in turn heats the circulating gas. Smaller materials move upward under the action of the gas. The aggregation mechanism can aggregate the smaller materials. As the volume of the material increases, its gravity increases, causing it to flow downward under gravity. The dried material flows to the bottom of the frame for storage under gravity.

[0006] Furthermore, the feeding mechanism includes a feed inlet, a feed hopper, a fixing spring, a connecting rod, a sealing block, and a sealing layer. The feed inlet is located above the separation chamber, and the feed hopper is threaded inside the feed inlet. By rotating the feed hopper, it can be connected to the feed inlet, thus facilitating the installation of the feed hopper. Since the feed hopper is funnel-shaped, it can prevent material spillage when the material flows into the separation chamber through the feed hopper, thereby increasing the utilization effect of the material.

[0007] Furthermore, a fixing spring is installed inside the lower end of the feed hopper, and a connecting rod is installed inside the lower end of the feed hopper. The side of the connecting rod is connected to the sealing block. The upper end of the sealing block is conical. The sealing block and the lower opening of the feed hopper are engaged. A sealing layer is provided on the side of the sealing block. When material is added, the material will fall onto the sealing block, thereby pushing the sealing block downward. At this time, the feed hopper will open, allowing the material in the feed hopper to flow downward into the interior of the separation chamber. When the sealing block moves, the connecting rod moves accordingly, and the fixing spring supports the connecting rod to ensure the stability of the sealing block during use. After the material in the feed hopper has finished flowing downward, the fixing spring will drive the connecting rod and the sealing block to move in the opposite direction. At this time, the sealing block will seal the opening of the feed hopper. The sealing layer is elastic, so it increases the sealing between the feed hopper and the sealing block, thereby ensuring that external gas will not flow inward and affect the material when the device is operating.

[0008] Furthermore, the left side of the separation chamber is arc-shaped, and a guide plate is provided at the lower left end of the interior of the separation chamber. When the device is in use, the circulating gas flows from the inside of the frame into the interior of the separation chamber, and then the gas flows back into the inside of the frame through the connecting pipe, thereby realizing the circulation of gas. Since the interior of the separation chamber is arc-shaped, the guide plate guides the gas as it flows along the separation chamber, causing the gas to flow along the guide plate. Meanwhile, the fan drives the gas in the intake pipe to flow in the opposite direction, causing the gas in the intake pipe to counteract the circulating gas. The gas temperature in the inlet pipe is low, so the gas in the inlet pipe will reduce the speed and temperature of the circulating gas. Then the gas will flow below the guide plate and enter the interior of the conveying pipe. Because the circulating gas is cooled, the water molecules in the circulating gas will liquefy into water droplets. And because the flow rate of the circulating gas is low, the water in the circulating gas will move in a parabolic motion under the action of gravity and then be collected by the water storage mechanism. The material has a large gravity, so the material will continue to move under its own inertia. Then the material will flow downward under its own gravity and flow downward through the conveying pipe into the interior of the frame.

[0009] Furthermore, the water storage mechanism includes a storage chamber, a filter block, a filter layer, a baffle, an absorption ball, and a fixing cap. The storage chamber and the separation chamber are threadedly connected. A filter block is embedded in the upper part of the storage chamber, and the filter layer is stored inside the filter block. The storage chamber is connected to the separation chamber by rotating it. The filter block has a porous internal structure and stores a filter layer made of sponge. Therefore, the filter layer can prevent material from flowing downwards without blocking water from flowing downwards, thus facilitating water storage and preventing excessive moisture content in the circulating gas.

[0010] Furthermore, inclined baffles are intersecting on both sides of the interior of the storage chamber. The storage chamber contains several absorption balls, and a fixing cap is installed at the lower end of the storage chamber. Water in the filter layer flows downward into the storage chamber under the action of gravity. The absorption balls are made of cotton material, so they absorb the water, thus preventing the water from flowing upward. The baffles inside the storage chamber further prevent the gas in the storage chamber from flowing upward, thereby preventing the moisture content in the circulating gas from being too high.

[0011] Furthermore, the heating mechanism includes a fixed frame, support rods, a heating mesh, an exhaust layer, and support blocks. The upper end of the fixed frame is arc-shaped, and several support rods are provided on the side of the fixed frame, with the other end of each support rod connected to the interior of the frame. Three layers of heating mesh are provided inside the fixed frame. An upward-opening exhaust layer is also provided inside the fixed frame. Support blocks are arranged at equal angles inside the exhaust layer, and a tubular partition layer is provided at the upper end of each support block. When the device is in use, the support rods support the fixed frame, creating a gap between the fixed frame and the frame for material to flow downwards. Simultaneously, gas enters the exhaust layer inside the fixed frame through a connecting pipe, and the heating mesh... The gas is heated to increase its temperature, and then flows outward through the openings in the exhaust layer. Because the exhaust layer openings are inclined, the gas flows upward along the fixed channel on the inner wall of the frame. The material is guided from the conveying pipe, causing it to flow downward along the tangent of the frame. This results in the gas and material flowing in opposite directions, both flowing along the inner wall of the frame. This increases the contact area between the circulating gas and the frame, increases the utilization rate of gas heat, and enhances the heating effect on the material. Heavier materials are heated by the gas and then flow downward, while lighter materials flow upward into the polymerization mechanism.

[0012] Furthermore, the polymerization mechanism includes a guide layer, a collection tank, polymerization holes, and air vents. The guide layer is hemispherical, with a collection tank at its upper end. The lower end of the collection tank is tubular, and the upper end is arc-shaped. Inclined downward air vents are located on the lower side of the collection tank. Polymerization holes are evenly distributed at the upper end of the collection tank. Lighter materials and gases flow upwards into the interior of the guide layer. Because the interior of the guide layer is inclined, the gas flows upwards along the inclined surface into the collection tank. Since the exhaust diameter of the air vents is larger than that of the polymerization holes, it prevents the material from flowing upwards through the polymerization holes during polymerization. The polymerization holes are closer to the vacuum pump, thus... The suction forces between the polymerization pores and the vents are balanced, with the suction force of the polymerization pores being slightly greater than that of the vents. As a result, the material gradually enters the interior of the polymerization pores along with the upward flow of gas. When there is a large amount of material in the polymerization pores, the material will polymerize under the action of the gas, thereby increasing the volume of the material. When the material is squeezed together and causes blockage of the polymerization pores, the polymerization pores cannot draw in air normally, and the air intake of the vents will inevitably increase, thus attracting the material and causing it to flow downwards. This prevents the material from being blocked by the polymerization pores. As the material moves, due to its greater weight, the material will flow downwards under its own gravity and inertia, thus flowing downwards through the separator layer and collecting the polymerized material.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: When in use, the present invention utilizes the inertia of the material and the wind force of the gas to separate the gas and the material. At the same time, the circulation is cooled and decelerated to absorb water vapor in the circulating gas. Then, the circulating gas is heated to make it flow upward, while the material flows downward, thereby realizing the reverse flow of the heated gas and the material, increasing the heating effect of the gas on the material. The lighter material will flow upward under the action of the gas, and the material will be aggregated by the suction of the aggregation pores. Then, the material will be separated from the aggregation pores by the attraction of the air pores. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figure 1 and Figure 8As shown, a vacuum spray granulator with gas-solid separation function includes a frame 1 and a vacuum pump 2. The vacuum pump 2 is installed at the upper end of the frame 1, and its side is connected to a separation chamber 3. A feeding mechanism is installed at the upper end of the separation chamber 3, and an air inlet pipe 10 is installed at the tail end of the separation chamber 3. A fan 11 is installed inside the separation chamber 3. A connecting pipe 19 is installed at the lower left end of the separation chamber 3 and is connected to the lower side of the frame 1. A conveying pipe 20 is installed at the middle of the lower end of the separation chamber 3. A water storage mechanism is installed inside the lower left side of the separation chamber 3. The conveying pipe 20 is connected to the upper side of the frame 1. The side of the connecting pipe 19 is connected to a heating mechanism, which is located at the lower interior of the frame 1. A polymerization mechanism is installed at the upper interior of the frame 1. A spiral-shaped... The fixed channel 26 is in shape. When the device is in use, the material is added into the separation chamber 3 through the feeding mechanism. The outside gas enters the separation chamber 3 through the air inlet pipe 10. The gas in the frame 1 is circulated by the vacuum pump 2. Then the gas will circulate in the separation chamber 3 and the frame 1 through the connecting pipe 19. The material will flow down from the inside of the separation chamber 3 to the inside of the frame 1 through the conveying pipe 20. The gas is heated by the heating mechanism, thereby heating the circulating gas. Smaller materials will move upward under the action of the gas. The smaller materials can be aggregated by the polymerization mechanism. When the volume of the material increases, its gravity will increase, and it will flow downward by gravity. The dried material will flow to the bottom of the frame 1 for storage under the action of gravity.

[0026] like Figure 3 As shown, the feeding mechanism includes a feed inlet 4, a feed hopper 5, a fixing spring 6, a connecting rod 7, a sealing block 8, and a sealing layer 9. The feed inlet 4 is located above the separation chamber 3. The feed hopper 5 is threaded inside the feed inlet 4. By rotating the feed hopper 5, it can be connected to the feed inlet 4, which facilitates the installation of the feed hopper 5. Since the feed hopper 5 is funnel-shaped, it can prevent material from spilling when the material flows into the separation chamber 3 through the feed hopper 5, thereby increasing the utilization effect of the material.

[0027] like Figure 2 and Figure 6As shown, a fixing spring 6 is installed inside the lower end of the feed hopper 5, and a connecting rod 7 is installed inside the lower end of the feed hopper 5. The side of the connecting rod 7 is connected to the sealing block 8. The upper end of the sealing block 8 is conical. The sealing block 8 and the lower opening of the feed hopper 5 are engaged. A sealing layer 9 is provided on the side of the sealing block 8. When material is added, the material will fall onto the sealing block 8, thereby pushing the sealing block 8 downward. At this time, the feed hopper 5 will open, allowing the material in the feed hopper 5 to flow downward into the interior of the separation chamber 3. When the closing block 8 moves, the connecting rod 7 moves accordingly, and the fixing spring 6 supports the connecting rod 7 to ensure the stability of the closing block 8 during use. After the material in the feed hopper 5 has finished flowing downwards, the fixing spring 6 will drive the connecting rod 7 and the closing block 8 to move in the opposite direction. At this time, the closing block 8 will seal the opening of the feed hopper 5. The sealing layer 9 is elastic, so it will increase the sealing between the feed hopper 5 and the closing block 8, thereby ensuring that when the device is running, the external gas will not flow inwards and affect the material.

[0028] like Figure 7 As shown, the left side of the separation chamber 3 is arc-shaped. A guide plate 12 is installed at the lower left end of the interior of the separation chamber 3. When the device is in use, the circulating gas flows from the inside of the frame 1 into the interior of the separation chamber 3. Then, the gas flows back into the frame 1 through the connecting pipe 19, thus achieving gas circulation. Since the interior of the separation chamber 3 is arc-shaped, the guide plate 12 guides the gas as it flows along the separation chamber 3, causing the gas to flow along the guide plate 12. Meanwhile, the fan 11 drives the gas in the intake pipe 10 to flow in the opposite direction, causing the gas in the intake pipe 10 to counteract the circulating gas. The gas temperature in the intake pipe 10 is relatively low, so the gas in the intake pipe 10 will reduce the speed and temperature of the circulating gas. Then the gas will flow below the guide plate 12 and enter the interior of the conveying pipe 20. Because the circulating gas is cooled, the water molecules in the circulating gas will liquefy into water droplets. And because the flow rate of the circulating gas is low, the water in the circulating gas will move in a parabolic motion under the action of gravity and then be collected by the water storage mechanism. The material has a large gravity, so the material will continue to move under its own inertia. Then the material will flow downward under its own gravity and flow downward through the conveying pipe 20 into the interior of the frame 1.

[0029] The water storage mechanism includes a storage chamber 13, a filter block 14, a filter layer 15, a baffle 16, an absorption ball 17, and a fixing cap 18. The storage chamber 13 is threadedly connected to the separation chamber 3. The filter block 14 is embedded in the upper end of the storage chamber 13. The filter layer 15 is stored inside the filter block 14. The storage chamber 13 is connected to the separation chamber 3 by rotating it. The filter block 14 has a porous structure inside and the filter layer 15 is stored inside the filter block 14. The filter layer 15 is made of sponge. Therefore, the filter layer 15 can prevent the material from flowing downwards without blocking the water from flowing downwards, thus facilitating water storage and preventing the moisture content of the circulating gas from being too high.

[0030] Inclined baffles 16 are arranged on both sides of the interior of the storage chamber 13. Several absorption balls 17 are stored inside the storage chamber 13. A fixing cap 18 is installed at the lower end of the storage chamber 13. Water in the filter layer 15 flows downward into the storage chamber 13 under the action of gravity. The absorption balls 17 are made of cotton material, so they absorb the water and prevent the water from flowing upward. The baffles 16 inside the storage chamber 13 can further prevent the gas in the storage chamber 13 from flowing upward, thereby preventing the moisture content in the circulating gas from being too high.

[0031] like Figure 4 As shown, the heating mechanism includes a fixed frame 21, support rods 22, heating mesh 23, exhaust layer 24, and support blocks 25. The upper end of the fixed frame 21 is arc-shaped, and several support rods 22 are provided on the side of the fixed frame 21. The other end of the support rods 22 is connected to the interior of the frame 1. Three layers of heating mesh 23 are provided inside the fixed frame 21. An exhaust layer 24 with an upwardly inclined opening is provided inside the fixed frame 21. Support blocks 25 are provided at equal angles inside the exhaust layer 24. A tubular partition layer 27 is provided at the upper end of the support block 25. When the device is in use, the support rods 22 support the fixed frame 21, thereby creating a gap between the fixed frame 21 and the frame 1 for material to flow downwards. At the same time, gas enters the exhaust layer 24 inside the fixed frame 21 through the connecting pipe 19. In the process, the heating grid 23 heats the incoming gas, thereby increasing its temperature. The gas then flows outward through the opening of the exhaust layer 24. Since the opening of the exhaust layer 24 is inclined, the gas flows upward along the fixed channel 26 on the inner wall of the frame 1. The material is guided from the conveying pipe 20, causing it to flow downward along the tangent of the frame 1. This results in the gas and material flowing in opposite directions, both along the inner wall of the frame 1, increasing the contact area between the circulating gas and the frame 1, increasing the utilization rate of gas heat, and enhancing the heating effect on the material. Heavier materials are heated by the gas and then flow downward, while lighter materials flow upward into the interior of the polymerization mechanism.

[0032] like Figure 5 As shown, the polymerization mechanism includes a guide layer 28, a collection tank 29, polymerization holes 30, and air holes 31. The guide layer 28 is hemispherical, with the collection tank 29 located at its upper end. The lower end of the collection tank 29 is tubular, and the upper end is arc-shaped. Inclined downward air holes 31 are provided on the lower side of the collection tank 29, and polymerization holes 30 are evenly distributed at the upper end of the collection tank 29. Lighter materials and gases flow upwards into the interior of the guide layer 28. Because the interior of the guide layer 28 is inclined, the gas flows upwards along the inclined surface into the interior of the collection tank 29. Since the exhaust diameter of the air holes 31 is larger than that of the polymerization holes 30, it prevents the material from flowing upwards through the polymerization holes 30 during polymerization. Furthermore, the polymerization holes 30 are closer to the vacuum pump 2. The suction force between the polymerization pore 30 and the air pore 31 is balanced, so that the suction force of the polymerization pore 30 is slightly greater than that of the air pore 31. Therefore, the material will gradually enter the interior of the polymerization pore 30 as the gas flows upward. When there is a lot of material in the polymerization pore 30, the material will polymerize under the action of the gas, thereby increasing the volume of the material. When the material is squeezed together and causes blockage of the polymerization pore 30, the polymerization pore 30 cannot draw in air normally, and the air intake of the air pore 31 will inevitably increase, thereby attracting the material and causing the material to flow downward, so that the material is no longer blocked by the polymerization pore 30. As the material moves, due to the greater weight of the material, the material will flow downward under the action of its own gravity and inertia, thereby flowing downward through the separator layer 27, and then collecting the polymerized material.

[0033] The working principle of this invention is as follows: When the device is in use, the material is first added into the feed hopper 5. Under the action of gravity, the closing block 8 moves downward, allowing the material to flow into the separation chamber 3 through the gap between the closing block 8 and the feed hopper 5. Then, the fixed spring 6 moves the closing block 8 to close the opening of the feed hopper 5. The material then flows into the conveying pipe 20 under the action of gravity. Because the material has a certain gravity, the circulating gas will not affect the downward flow of the material. The supplementary gas contains water vapor and mixed particles. When the mixed particles come into contact with the material, due to the poor adhesion between the two, the mixed particles will adhere to the material under the action of the gas. Separation is performed. The circulating gas, heated by the heating mesh 23, flows upwards, while the material flows downwards into the frame 1. This causes the heated mixed particles and water vapor to spray onto the material. Due to the high temperature of the gas and water mist, the water vapor on the surface of the material evaporates quickly. As the water vapor evaporates, the mixed particles and the material are mixed. Smaller particles move upwards under gravity and enter the interior of the polymerization hole 30. The suction of the polymerization hole 30 is used to polymerize the material. Then, the suction of the air hole 31 is used to separate the material from the polymerization hole 30. Finally, the gravity and inertia of the material cause it to move downwards to complete the collection of the polymer material.

[0034] The gas then flows back into the separation chamber 3 through the frame 1. At this time, the temperature of the water vapor will also decrease. At the same time, the supplementary cooling gas is used to cool and slow down the circulating gas, causing the water in the gas to condense and liquefy. The material is greatly affected by inertia, so the material will move forward under the action of inertia and flow into the interior of the conveying pipe 20 to achieve gas-solid separation. The liquefied water will move in the opposite direction under the action of the gas, and then flow into the interior of the storage chamber 13 under the action of gravity. The water is absorbed by the filter layer 15 and the absorption ball 17 to avoid the water content in the device being too high. The circulating gas that has undergone gas-water separation will enter the interior of the fixed frame 21 through the connecting pipe 19, and then be heated by the heating net 23.
