Description

Technical Field

[0001] The present invention relates to a multi-stage intelligent adjustable cyclone atomization granulation system and device, belonging to the technical field of atomization granulation. Background Art

[0002] In traditional cyclone atomization granulation devices, the atomization granulation process often faces many challenges. On the one hand, the conveying and mixing methods of the liquid material and the gas are not ideal enough. It is difficult for the liquid material conveying and the gas conveying to form an effective synergy, resulting in the liquid material being unable to be fully dispersed into fine and uniform liquid droplets. This makes the sizes of the subsequent formed granules uneven and the uniformity poor, seriously affecting the quality and performance of the products and making it difficult to meet the market demand for high-quality products. On the other hand, there are great limitations in the adjustment of the material crushing specifications in traditional devices. Usually, only single or limited crushing specification adjustments can be achieved, and it is impossible to flexibly adjust according to different production requirements. When facing diversified production requirements, traditional devices seem powerless, with poor applicability and flexibility, and it is difficult to meet the requirements of different production processes and product specifications. This not only restricts the improvement of production efficiency but also increases production costs because enterprises may need to purchase multiple devices with different specifications to cope with different production tasks. Therefore, a multi-stage intelligent adjustable cyclone atomization granulation system and device are proposed. Summary of the Invention

[0013] When the housing rotates, the spray heads of different specifications are alternately communicated with the first spraying holes through the second spraying holes.

[0014] The adjusting component further includes:

[0015] A fixing sleeve that is fixed on the outer wall of the mixing head;

[0016] A chute that is arranged in a zigzag shape on the outer wall of the fixing sleeve, and the chute includes a plurality of vertical grooves and a plurality of inclined grooves that are alternately arranged;

[0018] Among them, the guide rod is slidably abutted against the bottom wall of the chute;

[0019] Step walls are arranged at the joints of the two ends of the vertical groove and the inclined groove. The step wall at the end of the vertical groove far from the second spraying hole makes the groove depth at the lower end of the vertical groove deeper than the groove depth at the lower end of the inclined groove. When the housing slides to move the second spraying hole away from the first spraying hole, the guide rod slides along the vertical groove;

[0020] The step wall at the end of the vertical groove close to the second spraying hole makes the groove depth at the upper end of the vertical groove shallower than the groove depth at the upper end of the inclined groove. When the housing slides to move the second spraying hole close to the first spraying hole, the guide rod slides along the inclined groove.

[0030] Compared with the prior art:

[0031] 1. In the mixing chamber of the present invention, the liquid delivery and gas delivery are coordinated to realize the atomization granulation process. One end of the liquid delivery pipe extends into the mixing chamber and is provided with a plurality of nozzles. The direction of the liquid sprayed out by the nozzles is perpendicular to the direction of the gas transported by the gas delivery pipe. At the same time, the air flow in the gas delivery pipe is guided to enter the mixing chamber in a high-speed spiral shape after being guided. This vertical intersection causes the liquid flow sprayed vertically from the nozzles to collide and shear violently with the high-speed spiral air flow, greatly enhancing the turbulence and mixing intensity of the fluid. On the one hand, the strong shearing action is beneficial to disperse the liquid into finer and more uniform liquid droplets, improving the quality of atomization, making the particles formed in the subsequent granulation more uniform and delicate, and helping to improve the quality and performance of the product. On the other hand, the enhanced fluid turbulence and mixing intensity can make the liquid and gas fully mixed, ensuring the stability and efficiency of the granulation process, reducing the waste of liquid, and improving the production efficiency.

[0032] 2. In the present invention, by rotating the outer shell, different specifications of nozzles are alternately communicated with the first material spraying holes, and a variety of aperture nozzles are integrated by using the second material spraying holes. The crushing specifications of the materials can be flexibly adjusted according to needs, realizing two-stage, three-stage or even more-stage adjustment, meeting diverse production requirements, and greatly improving the applicability and flexibility of the device.

[0053] The present invention will be described below with specific embodiments, but it is not a limitation of the invention.

[0054] Embodiment 1

[0055] As Figures 1 - 8 shown, in this embodiment, a multi-stage intelligent adjustable cyclone atomization granulation device is provided, which includes a first end cover 1 and a second end cover 2. An exhaust port 201 is provided at the upper end of the second end cover 2, and a discharge port 202 is provided at the lower end of the second end cover 2. A rotatable drum 3 is arranged between the first end cover 1 and the second end cover 2. A plurality of heat pipes 7 for heating the inner cavity of the drum 3 are arranged inside the drum 3. Both ends of each heat pipe 7 are respectively fixed on the first end cover 1 and the second end cover 2. Among them, one end of the heat pipe 7 extends to the outside (as Figure 2 shown, one end of the heat pipe 7 penetrates through the first end cover 1), and the end of the heat pipe 7 extending to the outside is connected to an external heat supply component. And through holes are respectively formed on the surface of the heat pipe 7 to ensure uniform heating of the material and avoid local overheating or insufficient heating. The heat supply component introduces hot gas into the heat pipe 7, and the hot gas then enters the drum 3 through the through holes on the heat pipe 7 to directly heat the inside, with high thermal efficiency and low energy consumption. A spiral conveying blade 301 is arranged on the inner wall of the drum 3. A mixing head 4 is further included. The mixing head 4 is fixed on the first end cover 1. A mixing chamber 401 is provided inside the mixing head 4. A plurality of first spraying holes 402 are circumferentially distributed on the end face of the mixing head 4; A gas delivery pipe 5 is fixed on the mixing head 4. The channel of the gas delivery pipe 5 is communicated with the mixing chamber 401. The gas delivery pipe 5 is used to deliver gas to the mixing chamber 401; A liquid delivery pipe 6 is arranged inside the gas delivery pipe 5. The liquid delivery pipe 6 is distributed along the axis of the gas delivery pipe 5. One end of the liquid delivery pipe 6 extends into the mixing chamber 401 and is provided with a plurality of nozzles 601. The plurality of nozzles 601 are circumferentially distributed around the axis of the liquid delivery pipe 6. A conical plug 14 is fixed at one end of the liquid delivery pipe 6 close to the nozzle 601. The end of the conical plug 14 inserted into the liquid delivery pipe 6 is conical, which is used to disperse the liquid material, facilitating the dispersion of the liquid material from the plurality of nozzles 601 into the mixing chamber 401. The liquid delivery pipe 6 is used to deliver the liquid material to the mixing chamber 401; Among them, the direction in which the nozzle 601 sprays out the liquid material is perpendicular to the direction in which the gas delivery pipe 5 delivers gas to the mixing chamber 401, forming a strong shearing effect, which is beneficial to generating finer and more uniform liquid droplets;

[0056] Inside the mixing chamber 401, the liquid material flow vertically ejected from the nozzle 601 collides and shears violently with the high-speed spiral gas flow entering from the gas delivery pipe 5. This vertical intersection greatly enhances the turbulence and mixing intensity of the fluid.

[0057] Embodiment 2

[0058] As Figure 2 、 Figure 3 and Figures 6 - 8As shown, on the basis of the first embodiment, in this embodiment, there is further an adjusting component 8 for adjusting the size of the crushed material. The adjusting component 8 includes a housing 801 which rotates on the outer wall of the mixing head 4; a plurality of second spraying holes 802 are circumferentially distributed on the side wall of the housing 801, and the number of the second spraying holes 802 is at least twice the number of the first spraying holes 402; wherein, nozzles 803 are arranged on the plurality of second spraying holes 802, and the nozzles 803 arranged on adjacent second spraying holes 802 have different specifications.

[0059] When the housing 801 rotates, the nozzles 803 of different specifications are alternately communicated with the first spraying holes 402 through the second spraying holes 802.

[0060] Threads are provided on the second spraying holes 802, and the second spraying holes 802 are detachably connected to the nozzles 803 through the threads. By integrating the nozzles 803 with various apertures through the plurality of second spraying holes 802, the material can be crushed in different specifications according to requirements.

[0061] Example 1: The number of the first spraying holes 402 is six, and the number of the second spraying holes 802 is twelve. The nozzles 803 on every two adjacent second spraying holes 802 have different specifications. For example, the two specifications of the nozzles 803 are 2 mm and 4 mm respectively. In this way, each specification of the nozzles 803 can be communicated with the first spraying holes 402 through the second spraying holes 802. If it is necessary to adjust the size of the crushed material, after driving the housing 801 to rotate by 30 degrees, another specification of the nozzles 803 can be communicated with the first spraying holes 402 through the second spraying holes 802. At this time, the secondary adjustment of the size of the crushed material can be quickly realized.

[0062] Example 2: The number of the first spraying holes 402 is six, and the number of the second spraying holes 802 is eighteen. The nozzles 803 on every three adjacent second spraying holes 802 have different specifications. For example, the three specifications of the nozzles 803 are 2 mm, 4 mm, and 6 mm respectively. In this way, each specification of the nozzles 803 can be communicated with the first spraying holes 402 through the second spraying holes 802. If it is necessary to adjust the size of the crushed material, after driving the housing 801 to rotate by 20 degrees, another specification of the nozzles 803 can be communicated with the first spraying holes 402 through the second spraying holes 802. After driving the housing 801 to rotate by 20 degrees again, another specification of the nozzles 803 can be communicated with the first spraying holes 402 through the second spraying holes 802. At this time, the tertiary adjustment of the size of the crushed material can be quickly realized.

[0063] And so on. According to the multiple relationship between the number of the second spraying holes 802 and the first spraying holes 402, the adjustment of various material crushing specifications can be realized.

[0064] In order to enable the outer shell 801 to rotate at a certain angle, the adjusting assembly 8 further includes a fixing sleeve 804 which is fixed on the outer wall of the mixing head 4; a chute 805 is formed in a serrated shape on the outer wall of the fixing sleeve 804, and the chute 805 includes a plurality of vertical grooves 8051 and a plurality of inclined grooves 8052 which are arranged alternately; a guide rod 806 is slidably connected to the side wall of the outer shell 801 through a spring 807, and the guide rod 806 is slidably connected in the chute 805; wherein, the guide rod 806 is slidably abutted against the bottom wall of the chute 805.

[0065] Step walls 8053 are arranged at the joints of the two ends of the vertical groove 8051 and the inclined groove 8052. The step wall 8053 at one end of the vertical groove 8051 far from the second spraying hole 802 makes the groove depth at the lower end of the vertical groove 8051 deeper than the groove depth at the lower end of the inclined groove 8052. When the outer shell 801 slides to move the second spraying hole 802 away from the first spraying hole 402, the guide rod 806 slides along the vertical groove 8051.

[0066] The step wall 8053 at one end of the vertical groove 8051 close to the second spraying hole 802 makes the groove depth at the upper end of the vertical groove 8051 shallower than the groove depth at the upper end of the inclined groove 8052. When the outer shell 801 slides to move the second spraying hole 802 close to the first spraying hole 402, the guide rod 806 slides along the inclined groove 8052, so that the outer shell 801 rotates relative to the mixing head 4 at a certain angle.

[0067] A plugging protrusion 4021 is arranged at one end of the first spraying hole 402 close to the second spraying hole 802, and a plugging groove 8021 is arranged at one end of the second spraying hole 802 close to the first spraying hole 402. The plugging protrusion 4021 is movably plugged in the plugging groove 8021.

[0068] A shoulder 8011 is fixed on the side wall of the outer shell 801; two cylinders 808 are arranged on the first end cover 1, and U-shaped blocks 809 are fixed on the output shafts of the two cylinders 808. The two U-shaped blocks 809 are respectively fork-connected on both sides of the shoulder 8011.

[0069] Operation process:

[0070] The cylinder 808 operates to push the outer shell 801 to slide through the shoulder 8011 by the U-shaped block 809. At this time, the guide rod 806 slides along the vertical groove 8051, and the plugging protrusion 4021 and the plugging groove 8021 are separated.

[0071] Then, the cylinder 808 operates to pull the outer shell 801 to slide through the shoulder 8011 by the U-shaped block 809. At this time, the guide rod 806 slides along the inclined groove 8052. During the sliding process of the guide rod 806, the outer shell 801 rotates until the guide rod 806 moves into another vertical groove 8051, and as Figure 7As shown, the right end of the vertical groove 8051 extends a part. When the guide rod 806 moves into the vertical groove 8051, the guide rod 806 is not at the end of the vertical groove 8051. Therefore, when the cylinder 808 continues to operate, the U-shaped slider 809 can still continue to pull the outer shell 801 to slide through the shoulder 8011. At this time, the angle of the outer shell 801 remains unchanged relative to the mixing head 4, and the outer shell 801 only slides along the axis direction of the mixing head 4. In this way, it can ensure that the corresponding insertion groove 8021 is inserted with the insertion protrusion 4021, realizing the adjustment of the material crushing specification.

[0072] The inner walls of the first spraying hole 402, the second spraying hole 802 and the nozzle 803 are sprayed with nano-ceramic coatings to improve the erosion resistance.

[0073] Embodiment 3

[0074] As Figure 3 And Figure 5 As shown, on the basis of the above embodiment, in this embodiment, one end of the air delivery pipe 5 close to the mixing head 4 is provided with a contraction channel 501 for increasing the wind speed, and the gradual reduction of the contraction channel 501 is 15°.

[0075] A sleeve 9 that can slide along the axis direction of the infusion pipe 6 is sleeved on the infusion pipe 6. A plurality of spiral guide vanes 10 are circumferentially distributed on the outer wall of the sleeve 9, and the guide vanes 10 are arranged in the contraction channel 501. Through the guiding action of the guide vanes 10, the air flow in the contraction channel 501 flows into the mixing chamber 401 in a high-speed spiral shape.

[0076] An oil cylinder 11 is fixed on the outer wall of the air delivery pipe 5, and a push-pull block 12 is fixed at the end of the output shaft of the oil cylinder 11;

[0077] A connecting rod 13 is fixed on the sleeve 9, and one end of the connecting rod 13 far from the sleeve 9 penetrates through the air delivery pipe 5 and is connected to the push-pull block 12.

[0078] Working principle:

[0079] When the oil cylinder 11 is started, the output shaft of the oil cylinder 11 drives the sleeve 9 to slide along the axis direction of the infusion pipe 6 through the push-pull block 12 and the connecting rod 13;

[0080] As Figure 5 As shown, when the output shaft of the oil cylinder 11 pushes the push-pull block 12 to the right, causing the connecting rod 13 to pull the sleeve 9 to slide, the sleeve 9 will drive the guide vane 10 to slide out of the contraction channel 501. As the guide vane 10 slides out of the contraction channel 501, the length of the guide vane 10 in the contraction channel 501 will become smaller. In this way, the wind speed can be reduced. On the contrary, when the output shaft of the oil cylinder 11 pulls the push-pull block 12 to the left, the length of the guide vane 10 in the contraction channel 501 will become longer and the wind speed will increase;

[0081] The wind speed and the swirl intensity can be adjusted in real time according to the process requirements without stopping the machine, optimizing the atomization state.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or equivalently replaced.
