Description

Technical Field

[0001] This utility model relates to the field of separation equipment technology, and in particular to a cyclone separator. Background Technology

[0002] A cyclone separator is a device used for separating gas-solid or liquid-solid systems. Its working principle relies on the rotational motion caused by the tangential introduction of airflow, which throws solid particles or liquid droplets with significant inertial centrifugal force towards the outer wall surface, separating them.

[0003] With technological advancements, some cyclone separators have achieved adjustable separation efficiency. Specific adjustment methods include: 1. Adjusting the depth of the exhaust pipe inserted into the cylindrical part of the cyclone separator. The deeper the insertion, the higher the separation efficiency; the shallower the insertion, the lower the separation efficiency. 2. Adjusting the inner diameter of the exhaust pipe. The smaller the inner diameter, the higher the separation efficiency; the larger the inner diameter, the lower the separation efficiency.

[0004] For example, the cyclone separator with adjustable separation efficiency disclosed in the prior art publication document "CN215427783U" includes components such as a cyclone inlet, top plate, exhaust pipe, cylinder, inverted conical long cone, and intermediate ash hopper. This cyclone separator achieves the purpose of adjusting the separation efficiency by replacing exhaust pipes of different sizes and models. Furthermore, the separation efficiency can be further adjusted by adjusting the diameter range formed by multiple triangular baffles installed on the outer surface of the exhaust pipe. The smaller the diameter range formed by the triangular baffles, the higher the separation efficiency; the larger the diameter range, the lower the separation efficiency. However, all of the above adjustments of this cyclone separator are achieved by replacing the exhaust pipe. Therefore, in order to adjust the separation efficiency, two or even more exhaust pipes need to be equipped. This not only increases the cost of adjusting the separation efficiency but also makes the adjustment work more complicated and cumbersome, and there are certain deficiencies in ease of use. Utility Model Content

[0005] The purpose of this invention is to solve the problem that adjusting the separation efficiency of cyclone separators in the existing technology is still cumbersome, complex and difficult to operate, and therefore a cyclone separator is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cyclone separator includes a cylindrical section and a conical section. The upper part of the cylindrical section is provided with an exhaust pipe. An inner sleeve and an outer sleeve are sequentially sleeved around the exhaust pipe from the inside to the outside. The outer sleeve is fixedly connected to the cylindrical section. Depth adjustment components are provided between the outer sleeve and the inner sleeve, and between the inner sleeve and the exhaust pipe, for adjusting the depth of the exhaust pipe inserted into the cylindrical section. The lower part of the exhaust pipe is provided with several retractable baffles. Each baffle is provided with a transmission component between itself and the inner sleeve, for driving the baffles to extend and retract and adjusting the diameter range formed by the baffles. An exhaust port is opened on the lower surface of the exhaust pipe, and a diameter adjustment component connected to the baffles is provided on the exhaust port.

[0008] In some embodiments, both depth adjustment components include an adjustment bolt and a nut threadedly connected to the adjustment bolt. The adjustment bolt in each of the two depth adjustment components is fixedly connected to the outer sleeve and the inner sleeve, respectively, and the nut in each of the two depth adjustment components is movably connected to the inner sleeve and the exhaust pipe, respectively.

[0009] In some embodiments, a plurality of the baffle blades are arranged in a ring array along the axis of the exhaust pipe, and each baffle blade includes a fan-shaped fixed plate and a fan-shaped movable plate. The fixed plate is fixedly connected to the outer surface of the exhaust pipe, and the movable plate is rotatably connected to the fixed plate via a rotating shaft.

[0010] In some embodiments, the transmission assembly includes an extension rod and a transmission rod, the extension rod being fixedly connected to the lower part of the inner sleeve, and the transmission rod being connected between the extension rod and the movable plate.

[0011] In some embodiments, the caliber adjustment assembly includes a first sliding plate and a second sliding plate. The number of the first sliding plate and the second sliding plate is several and the same as the number of movable plates. The several first sliding plates are arranged in a ring array along the axis of the exhaust pipe and are slidably connected to the lower surface of the exhaust pipe along the radial direction of the exhaust pipe. The several second sliding plates are arranged in a ring array along the axis of the exhaust pipe, and the several second sliding plates are intersected with the several first sliding plates to form a ring plate.

[0012] In some embodiments, connecting bolts are inserted into both sides of the first sliding plate, and connecting grooves are provided on both sides of the second sliding plate, with the connecting bolts on both sides of the first sliding plate respectively inserted into the adjacent connecting grooves.

[0013] In some embodiments, a connecting rod is connected between the first sliding plate and the adjacent movable plate.

[0014] In some embodiments, a first sealing sleeve is provided between the outer sleeve and the inner sleeve, and a second sealing sleeve is provided between the inner sleeve and the exhaust pipe.

[0015] Compared with the prior art, the present invention provides a cyclone separator with the following advantages:

[0016] 1. By coordinating the outer sleeve, inner sleeve, and depth adjustment components, the nuts on the inner sleeve and exhaust pipe can be turned to drive the exhaust pipe to slide up or down. Therefore, the depth of the exhaust pipe inserted into the cylindrical part can be adjusted, thereby adjusting the separation efficiency of the cyclone separator. Moreover, through dual adjustment, the stroke of the exhaust pipe sliding up and down can be increased, thereby increasing the adjustment range and ensuring its adaptability.

[0017] 2. Through the coordinated arrangement of the baffle blades, the diameter adjustment assembly, the transmission assembly, and the connecting rod, when the depth of the exhaust pipe inserted into the cylindrical part is adjusted by turning the nut on the exhaust pipe, the diameter formed by the four movable plates is also adjusted, as well as the diameter of the channel through which the air in the separator enters the exhaust pipe. Furthermore, this adjustment can simultaneously increase or decrease the separation efficiency of the cyclone separator, thus eliminating the need for separate adjustments to each component, making the adjustment work more convenient, quick, and easy to operate.

[0018] 3. Furthermore, it achieves the goal of adjusting the separation efficiency through adjustment, eliminating the need to equip the separator with multiple models of exhaust pipes, which can reduce adjustment and usage costs to a certain extent.

[0019] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Reference Figure 1-5 A cyclone separator includes a cylindrical part 10 and a conical part 11. The upper end of the conical part 11 is fixedly connected to the lower end of the cylindrical part 10. A bracket 15 is fixedly connected to the outside of the cylindrical part 10 and the conical part 11. An air inlet 12 is provided on the upper side of the cylindrical part 10, and a discharge port is provided at the lower end of the conical part 11. A discharge device 13 is installed on the discharge port for discharging solid particles separated from the air.

[0033] The upper part of the cylindrical part 10 is provided with an exhaust pipe 14. An inner sleeve 2 and an outer sleeve 1 are sequentially sleeved on the outside of the exhaust pipe 14 from the inside to the outside. The outer sleeve 1 is fixedly connected to the cylindrical part 10. The exhaust pipe 14 can slide up or down inside the inner sleeve 2. The inner sleeve 2 and the exhaust pipe 14 can also slide up or down on the outer sleeve 1. A first sealing sleeve 4 is installed inside the outer sleeve 1 and sleeved on the outside of the inner sleeve 2 to ensure the sealing between the outer sleeve 1 and the inner sleeve 2. A second sealing sleeve 5 is installed inside the inner sleeve 2 and sleeved on the outside of the exhaust pipe 14 to ensure the sealing between the inner sleeve 2 and the exhaust pipe 14. The first sealing sleeve 4 and the second sealing sleeve 5 are sliding sealing sleeves, which can be slidably adjusted while ensuring sealing.

[0034] A depth adjustment component 3 is provided between the outer sleeve 1 and the inner sleeve 2, and between the inner sleeve 2 and the exhaust pipe 14, for adjusting the depth of the exhaust pipe 14 inserted into the cylindrical part 10. The lower part of the exhaust pipe 14 is provided with four retractable baffles 6. Each baffle 6 is provided with a transmission component 8 between it and the inner sleeve 2, for driving the four baffles 6 to extend and retract and adjust the diameter range formed by the four baffles 6. An exhaust port 1401 is opened on the lower surface of the exhaust pipe 14, and a diameter adjustment component 7 connected to the baffles 6 is provided on the exhaust port 1401.

[0035] Reference Figure 3-4 Both depth adjustment components 3 include an adjustment bolt 301 and a nut 302 threadedly connected to the adjustment bolt 301. The adjustment bolt 301 in the two depth adjustment components 3 is fixedly connected to the outer sleeve 1 and the inner sleeve 2, respectively. The nut 302 in the two depth adjustment components 3 is movably connected to the inner sleeve 2 and the exhaust pipe 14, respectively. Specifically, two connecting seats 303 are welded to the outer surfaces of the inner sleeve 2 and the exhaust pipe 14 near the nut 302. The nut 302 is placed between the two connecting seats 303, and the adjustment bolt 301 passes through the two connecting seats 303.

[0036] Four spoiler blades 6 are arranged in a ring array along the axis of the exhaust pipe 14, and each spoiler blade 6 includes a fan-shaped fixed plate 601 and a fan-shaped movable plate 602. The fixed plate 601 is fixedly connected to the outer surface of the exhaust pipe 14, and the movable plate 602 is rotatably connected to the fixed plate 601 through a rotating shaft. The center of the movable plate 602 and the center of the fixed plate 601 coincide with the rotating shaft between them. The movable plate 602 is hollow with an opening on one side and is movably sleeved on the outside of the fixed plate 601.

[0037] The transmission assembly 8 includes an extension rod 801 and a transmission rod 802. The extension rod 801 is fixedly connected to the lower part of the inner sleeve 2 along the axial direction of the inner sleeve 2. One end of the transmission rod 802 is hinged to the extension rod 801 through a hinge shaft, and the other end is hinged to the movable plate 602 through a hinge shaft.

[0038] Reference Figure 6-8 The caliber adjustment component 7 includes an arc-shaped first sliding plate 701 and an arc-shaped second sliding plate 702. There are four first sliding plates 701 and four second sliding plates 702. The four first sliding plates 701 are arranged in a ring array along the axis of the exhaust pipe 14 and are slidably connected to the lower surface of the exhaust pipe 14 along the radial direction of the exhaust pipe 14. The several second sliding plates 702 are arranged in a ring array along the axis of the exhaust pipe 14, and the four second sliding plates 702 and the four first sliding plates 701 are intersected and form a ring plate.

[0039] Each first sliding plate 701 has connecting bolts 704 inserted on both sides, and each second sliding plate 702 has rectangular connecting slots 703 on both sides. The connecting bolts 704 on both sides of the first sliding plate 701 are respectively inserted into the connecting slots 703 adjacent to them. Specifically, the second sliding plate 702 is located between the lower surface of the exhaust pipe 14 and the upper surface of the first sliding plate 701. One of the connecting bolts 704 on the first sliding plate 701 is inserted into the connecting slot 703 on one of the adjacent second sliding plates 702, and the other connecting bolt 704 is inserted into the connecting slot 703 on another adjacent second sliding plate 702. This achieves a sliding connection between the two sides of the first sliding plate 701 and the two adjacent second sliding plates 702. The connecting groove 703 is a stepped groove, and the connecting bolt 704 is an internal hex bolt. The connecting bolt 704 passes through the connecting groove 703, passes through the second sliding plate 702, and then passes through the first sliding plate 701. An upper limit nut is installed on the thread of the connecting bolt 704 located below the first sliding plate 701. The upper limit nut does not need to be tightened when it is installed. It is necessary to ensure that the first sliding plate 701 and the second sliding plate 702 can slide relative to each other.

[0040] Four linear slide rails 705 are fixedly connected radially to the lower surface of the exhaust pipe 14, and sliders 706 are fixedly installed on each of the four first sliding plates 701. The sliders 706 are slidably connected to the slide rails 705 to ensure the stability of the first sliding plates 701 when they slide.

[0041] A connecting rod 9 is connected between the first sliding plate 701 and the adjacent movable plate 602. Specifically, one end of the connecting rod 9 is hinged to the first sliding plate 701 via a hinge pin, and the other end is hinged to the movable plate 602 via a hinge pin.

[0042] In this invention, when the cyclone separator is working, air containing solid particles enters the cylindrical section 10 through the air inlet 12 and rotates inside the cylindrical section 10 to form an outer vortex. The air then spirals downward along the inner wall of the cylindrical section 10 into the conical section 11. Under the action of centrifugal force, the solid particles in the air are thrown towards the inner wall of the cylindrical section 10. After contacting the inner wall of the cylindrical section 10, they lose inertia and fall down along the wall surface, entering the discharge port at the lower end of the conical section 11. In addition, under the action of the conical section 11, the rotating and descending airflow forms an upward rotating inner vortex during the descent. The upward inner vortex can then enter the exhaust pipe 14 through the exhaust port 1401 and finally be discharged outward. In this process, the solid particles in the air can be removed.

[0043] When it is necessary to adjust the separation efficiency of the cyclone separator, the nut 302 on the inner sleeve 2 can be turned with a wrench, which will cause the inner sleeve 2 to slide up or down under the action of the adjusting bolt 301 connected to it. This will cause the exhaust pipe 14 to slide up or down synchronously, thereby adjusting the depth of the exhaust pipe 14 inserted into the cylindrical part 10. Furthermore, the nut 302 on the exhaust pipe 14 can be turned with a wrench, which will directly cause the exhaust pipe 14 to slide up or down under the action of the adjusting bolt 301 connected to it. Therefore, the depth of the exhaust pipe 14 inserted into the cylindrical part 10 can also be adjusted, thereby adjusting the separation efficiency of the cyclone separator. Moreover, through dual adjustment, the stroke of the exhaust pipe 14 sliding up and down can be increased, thereby increasing the adjustment range.

[0044] The initial state of the spoiler blades 6 and the diameter adjustment assembly 7 is as follows: Figure 6 As shown, during the process of moving the exhaust pipe 14 downward by turning the nut 302 on the exhaust pipe 14, the depth of the exhaust pipe 14 inserted into the cylindrical part 10 increases, thus improving the separation efficiency of the cyclone separator. During this process, the exhaust pipe 14 slides downward on the inner sleeve 2, and the distance from the lower end of the exhaust pipe 14 to the lower end of the inner sleeve 2 gradually increases. During this process, the upper ends of the extension rod 801 and the transmission rod 802 on the inner sleeve 2 do not move. Under the pull of the lower end of the transmission rod 802, the movable plate 602 can be driven to rotate around the pivot on the fixed plate 601 towards the exhaust pipe 14, and the four movable plates 602 rotate synchronously, thereby reducing the diameter formed by the four movable plates 602 (the reduced diameter is as shown in the figure). Figure 9As shown), this will further improve the separation efficiency of the cyclone separator. Similarly, as the exhaust pipe 14 is moved upward by turning the nut 302 on the exhaust pipe 14, the distance from the lower end of the exhaust pipe 14 to the lower end of the inner sleeve 2 gradually decreases, and under the push of the lower end of the transmission rod 802, the movable plate 602 rotates around the pivot on the fixed plate 601 in a direction away from the exhaust pipe 14, thereby increasing the diameter formed by the four movable plates 602 (the increased diameter is shown in the figure). Figure 10 As shown, this will further reduce the separation efficiency of the cyclone separator. Thus, while adjusting the depth of the exhaust pipe 14 inserted into the cylindrical part 10, the diameter formed by the four movable plates 602 is also adjusted. This adjustment can simultaneously increase or decrease the separation efficiency of the cyclone separator.

[0045] Furthermore, as the movable plate 602 rotates around the pivot on the fixed plate 601 towards the exhaust pipe 14, the movable plate 602 also pushes the first sliding plate 701 to slide towards the axis of the exhaust pipe 14 via the connecting rod 9. During this process, the first sliding plate 701 drives the second sliding plate 702 to slide towards the axis of the exhaust pipe 14 via the connecting bolt 704 and the connecting groove 703, thereby reducing the inner diameter of the annular plate formed by the first sliding plate 701 and the second sliding plate 702, and thus reducing the diameter of the passage used for air to enter the exhaust pipe 14 (the reduced diameter is as follows). Figure 9 As shown), this improves the separation efficiency of the cyclone separator. Similarly, while the movable plate 602 rotates around the axis on the fixed plate 601 in a direction away from the exhaust pipe 14, the movable plate 602 also pulls the first sliding plate 701 to slide away from the axis of the exhaust pipe 14 via the connecting rod 9. During this process, the first sliding plate 701 drives the second sliding plate 702 to slide away from the axis of the exhaust pipe 14 via the connecting bolt 704 and the connecting groove 703, thereby increasing the inner diameter of the annular plate formed by the first sliding plate 701 and the second sliding plate 702, and thus increasing the diameter of the passage through which the air in the separator enters the exhaust pipe 14 (the increased diameter is shown in the figure). Figure 10 As shown in the figure, this reduces the separation efficiency of the cyclone separator.

[0046] Therefore, when the depth of the exhaust pipe 14 inserted into the cylindrical part 10 is adjusted by turning the nut 302 on the exhaust pipe 14, the diameter formed by the four movable plates 602 is also adjusted, and the diameter of the channel through which the air in the separator enters the exhaust pipe 14 is also adjusted. Furthermore, the separation efficiency of the cyclone separator can be increased or decreased simultaneously through this adjustment, so it is no longer necessary to adjust the corresponding components separately.

[0047] Furthermore, when it is necessary to simultaneously adjust the depth of the exhaust pipe 14 inserted into the cylindrical part 10, the diameter formed by the four movable plates 602, and the diameter of the channel through which the air in the separator enters the exhaust pipe 14, this can be achieved by turning the nut 302 on the exhaust pipe 14. When it is only necessary to adjust the depth of the exhaust pipe 14 inserted into the cylindrical part 10, this can be achieved by turning the nut 302 on the inner sleeve 2. This allows for multiple adjustment modes, providing two options for adjusting the separation efficiency and improving the flexibility and adaptability of the adjustment work.
