Abstract
Description
Technical Field
[0001] This utility model belongs to the field of separation equipment technology, and in particular relates to a multi-stage flow-guiding cyclone separator. Background Technology
[0002] Cyclone separators are devices that use centrifugal force to separate gas-solid mixtures. They are widely used in chemical, environmental protection and other fields. Traditional single-stage cyclone separators have problems such as limited separation efficiency and high pressure drop, making it difficult to meet the requirements of high-purity separation. Multi-stage flow-guided cyclone separators can gradually enhance the centrifugal separation effect, reduce airflow disturbance and improve fine particle capture efficiency by optimizing the flow-guided structure. At the same time, the staged flow-guided design balances the separation efficiency and pressure drop, making it suitable for high-precision gas-solid separation scenarios. However, its structural complexity and manufacturing cost still need to be further optimized.
[0003] However, existing multi-stage cyclone separators are not easy to adjust when the mixture enters the separator, making it difficult for the device to adapt to impurity particles of different diameters. When the wind speed is too low, small impurities are difficult to separate, while when the wind speed is too high, the separated particles will be rolled up again due to the increased airflow turbulence. Utility Model Content
[0004] The purpose of this utility model is to provide a multi-stage guide cyclone separator. By setting a speed regulating unit, it solves the problem that existing multi-stage guide cyclone separators are not convenient to adjust the speed of the mixture entering the separator during use, which makes it difficult for the device to adapt to impurity particles of different diameters. When the wind speed is too low, small particles are difficult to separate, while when the wind speed is too high, the separated particles will be re-rolled up due to the increased airflow turbulence.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a multi-stage flow-guiding cyclone separator, comprising a shell and a connecting pipe disposed on the left side of the shell, and further comprising: a separation section, which is installed on the right side of the shell and is used to separate particulate impurities in the mixture; a speed regulating section, which is located inside the shell and is used to regulate the flow rate of the mixture; and a blocking section, which is disposed inside the connecting pipe and is used to block large-volume impurities in the mixture; wherein, the mixture passes through the blocking section and enters the separation section under the action of the speed regulating section, and the separation of impurities is completed under the action of the separation section.
[0007] Furthermore, the separation section includes a connecting pipe two disposed on the right side of the outer casing, a separator disposed on the right side of the connecting pipe two, a connecting pipe three fixedly connected to the inner wall of the separator, and a plurality of guide vanes fixedly connected to the inner wall of the separator; wherein, the top of the connecting pipe three extends to the outside of the separator, the bottom of the connecting pipe three extends to the inside of the separator, and the plurality of guide vanes are circumferentially distributed.
[0008] Furthermore, the speed regulating unit includes a moving component located inside the housing for providing power; and a pressing component, wherein a plurality of pressing components are provided and all of the pressing components are installed inside the housing; wherein the plurality of pressing components are circumferentially distributed, and the moving component is used to drive the plurality of pressing components to move closer to each other.
[0009] Furthermore, the barrier includes a partition plate fixedly connected to the inner wall of the connecting pipe, and a bracket fixedly connected to the inner wall of the connecting pipe. A rotating component is disposed within the bracket. The bracket is located on the right side of the partition plate, the partition plate is a circular plate with gaps, and the bracket is a cross plate. The rotating component includes a rotating shaft rotatably connected to the inner wall of the bracket. A scraper is fixedly connected to the outer wall of the rotating shaft, and a fan is fixedly connected to the outer wall of the rotating shaft. The rotating shaft passes through the partition plate, the bracket, the scraper, and the fan. The scraper is located on the left side of the partition plate, and the fan is located on the right side of the bracket. This allows for cleaning of the partition plate and sweeping away large-volume impurities, thereby extending the service life of the device.
[0010] Furthermore, the moving component includes a rubber tube disposed within a housing, with two sliders slidably connected to the inner wall of the housing, and a power component disposed within the housing; wherein the left side of the rubber tube is connected to a first connecting pipe, and the right side of the rubber tube is connected to a second connecting pipe, the power component includes a limiting rod fixedly connected to the inner wall of the housing, a bidirectional threaded rod rotatably connected to the inner wall of the housing, and a motor fixedly connected to the inner wall of the housing, the output shaft of the motor being fixedly connected to the bidirectional threaded rod via a coupling; wherein the limiting rod passes through the two sliders, the inner walls of both sliders are slidably connected to the limiting rod, the bidirectional threaded rod passes through the two sliders, and the outer walls of both bidirectional threaded rods are threadedly connected to the sliders, by setting up the moving component, power can be provided to move several extrusion components closer to each other, thereby adjusting the connecting area of the rubber tube.
[0011] Furthermore, the extrusion assembly includes an extrusion block fixedly connected to the outer wall of the rubber tube. The extrusion block has a limiting groove, and two limiting bolts are provided in the limiting groove. The side of the two limiting bolts away from the extrusion block is fixedly connected to two sliders respectively. The limiting bolts are rods with balls at the bottom, and the limiting bolts move under the restriction of the limiting groove. By setting the extrusion assembly, they can move closer to each other evenly under the action of the moving assembly, thereby ensuring that the rubber tube contracts and stretches evenly.
[0012] This utility model has the following beneficial effects:
[0013] 1. By setting up a speed regulating unit, when it is necessary to adjust the speed at which the mixture enters the separator, the motor can be started, and its output shaft drives the bidirectional threaded rod to rotate. Under the action of the limit rod, the two sliders move closer or further apart. At this time, under the action of the limit bolt and the limit groove, the extrusion block moves closer or further away from the inner wall of the outer shell, thereby stretching or extruding the rubber tube and changing the flow area of the rubber tube. This allows for adjustment of the speed at which the mixture flows into the separator, preventing the wind speed from being too low and making it difficult to separate small particles of impurities. It also prevents the wind speed from being too high and blowing away the separated impurities, thus ensuring the stable operation of the device.
[0014] 2. By setting up a barrier, when the mixture passes through the connecting pipe, it will first pass through the baffle. Under the action of the baffle, large impurities in the mixture will be separated on the left side of the baffle. When the mixture passes through the fan, it will blow the fan and make it rotate, thereby driving the scraper to rotate through the rotating shaft, sweeping off the large impurities on the baffle. This can block large impurities in the mixture from entering the device and clogging it, thus further ensuring the stable operation of the device.

A motor 215 is fixedly connected to the inner wall of the housing 101, and the output shaft of the motor 215 is connected to the bidirectional threaded rod 214 via a coupling. The device is fixedly connected; a limiting rod 213 passes through two sliders 212, and the inner walls of both sliders 212 are slidably connected to the limiting rod 213. A bidirectional threaded rod 214 passes through two sliders 212, and the outer walls of both bidirectional threaded rods 214 are threadedly connected to the sliders 212. The extrusion assembly 22 includes an extrusion block 221 fixedly connected to the outer wall of the rubber tube 211. A limiting groove 222 is opened on the extrusion block 221, and two limiting bolts 223 are provided in the limiting groove 222.

The limiting bolt 223 is a rod with a ball at the bottom, and the limiting bolt 223 moves under the restriction of the limiting groove 222. By setting the speed regulating part 2, the speed of the mixture entering the separator 104 can be adjusted to avoid the situation where the wind speed is too low and small particles are difficult to separate. At the same time, it can also prevent the wind speed from being too high and blowing up the separated impurities, thereby ensuring the stable operation of the device.
[0030] The barrier section 3 includes a partition 301 fixedly connected to the inner wall of the connecting pipe 102. A bracket 302 is fixedly connected to the inner wall of the connecting pipe 102, and a rotating component is disposed inside the bracket 302. The bracket 302 is located to the right of the partition 301. The partition 301 is a circular plate with gaps, while the bracket 302 is a cross plate. The rotating component includes a rotating shaft 303 rotatably connected to the inner wall of the bracket 302. A scraper 304 is fixedly connected to the outer wall of the rotating shaft 303, and a fan 305 is fixedly connected to the outer wall of the rotating shaft 303. The rotating shaft 303 passes through the partition 301, the bracket 302, the scraper 304, and the fan 305. The scraper 304 is located to the left of the partition 301, and the fan 305 is located to the right of the bracket 302. By setting the barrier section 3, large impurities present in the mixture can be blocked outside the device, preventing them from entering the device and clogging it, thereby further ensuring the stable operation of the device.
[0031] A specific application of this embodiment is as follows: When it is necessary to separate a mixture, the mixture can be passed from the first connecting pipe 102 through the speed regulating part 2 and the blocking part 3, and finally transported to the separator 104 through the second connecting pipe 103. After the mixture is transported into the separator 104, it will spiral downward under the action of several guide vanes 106, thereby forming a cyclone. Impurities in the mixture will fall to the inner wall of the separator 104 under the action of centrifugal force, and then be discharged from the bottom of the separator 104 under the action of gravity. The separated air will move upward from the middle area of the separator 104 and finally be discharged from the third connecting pipe 105. When the mixture passes through the first connecting pipe 102, it will first pass through the partition 301, and under the action of the partition 301, the large volume impurities present in the mixture will be separated. On the left side of plate 301, when the mixture passes through fan 305, it will blow the fan 305, causing it to rotate. This will drive scraper 304 to rotate via shaft 303, sweeping away large impurities on partition 301. When it is necessary to adjust the speed at which the mixture enters separator 104, motor 215 can be started, causing its output shaft to drive bidirectional threaded rod 214 to rotate. This will cause two sliders 212 to move closer or further apart under the action of limit rod 213. At this time, under the action of limit bolt 223 and limit groove 222, extrusion block 221 will move closer or further away from the inner wall of outer shell 101, thereby stretching or extruding rubber tube 211, changing the flow area of rubber tube 211, and thus adjusting the speed at which the mixture flows into separator 104.
