[0045] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] like Figures 1 to 9 As shown, an embodiment of the utility model provides a rotation switch type online adjustable bottom flow port, which is used for a cyclone and is arranged at the end of the cyclone; the rotation switch type online adjustable bottom flow port comprises: a driving assembly 21, a rotating member 22, an adjusting section 23 and a guiding and pressing assembly; the driving assembly 21 is transmission-connected with the rotating member 22 and drives the rotating member 22 to rotate; at least one adjusting section 23 is provided, and the adjusting section 23 has a first large head end 231 and a first small head end 232, and the adjusting section 23 is arranged on the rotating member 22 through the first large head end 231; a guiding and pressing assembly is provided at the outer edge of the end of the cyclone, or a guiding and pressing assembly is provided at the outer edge of the first large head end 231; under the action of the driving assembly 21, the end of the cyclone can be selectively communicated with the first large head end 231, and when the first large head end 231 moves to the end of the cyclone, the guiding and pressing assembly is used to guide the first large head end 231 and press the first large head end 231 with the end of the cyclone.

[0047] The rotary switchable online adjustable bottom flow port provided in this embodiment is used to adjust the diameter of the bottom flow port of the cyclone, so as to adapt to raw coal with different characteristics. Specifically, the drive assembly 21 can be a reduction motor, or an internal combustion engine or a hydraulic motor. The end of the cyclone can discharge materials, and the drive assembly 21 can be fixed on the outer wall of the cyclone, or it can be arranged on the side of the cyclone. The drive assembly 21 is used to drive the rotating member 22 to rotate. The rotating member 22 is a plate-like structure. For example, the rotating member 22 can be a circular plate or a square plate, or it can be a hollow frame. An internal threaded hole is provided at the center of the end face of the output shaft of the drive assembly 21, and a through hole is provided on the rotating member 22. The through hole is connected to the internal threaded hole by a screw, so that the rotating member 22 is fixed to the output shaft of the drive assembly 21, so that the drive assembly 21 can drive the rotating member 22 to rotate. The center of the through hole is also the rotation center of the rotating member 22. The adjusting section 23 is a conical or cylindrical tube-shaped structure on the outside and a conical structure on the inside. At least one adjusting section 23 is provided. The adjusting section 23 has two opposite ends, namely a first large end 231 and a first small end 232. The inner diameter of the first large end 231 is larger than the inner diameter of the first small end 232. The inner wall of the adjusting section 23 is smoothly provided. Preferably, the inner diameter of the first large end 231 is the same as the inner diameter of the end of the cyclone. A mounting hole is provided on the rotating member 22. The adjusting section 23 is passed through the mounting hole and is detachably connected to the outer edge of the mounting hole by a flange and bolts to facilitate the replacement of the adjusting section 23 and avoid affecting the function of the adjusting section 23. When in use, the driving assembly 21 drives the rotating member 22 to rotate, so that the first large end 231 can be connected or separated from the end of the cyclone to adjust the caliber of the bottom flow port.

[0048] Specifically, when the first large head end 231 is connected to the end of the cyclone, the material flow discharged from the end of the cyclone enters the regulating section 23 and is discharged from the first small head end 232 .

[0049] In this embodiment, at least one adjusting section 23 of the above-mentioned rotary switchable online regulating bottom flow outlet is provided. When one adjusting section 23 is provided, when the adjusting section 23 is connected to the end of the cyclone, the adjusting section 23 is the bottom flow outlet of the cyclone. When the adjusting section 23 is separated from the end of the cyclone, the end of the cyclone is the bottom flow outlet of the cyclone. Since the length of the cyclone also has a certain influence on its use effect, it is preferred that a plurality of adjusting sections 23 are provided, and only the adjusting section 23 is used as the bottom flow outlet of the cyclone to avoid changing the working length of the cyclone when changing the caliber of the bottom flow outlet of the cyclone. At this time, by switching each adjusting section 23, the caliber of the bottom flow outlet of the cyclone can be adjusted to adapt to materials of different properties.

[0050] Optionally, in this embodiment, due to the limited carrying capacity of the rotating member 22, the cyclone can be equipped with a plurality of rotating switchable online adjustable bottom flow ports to give the cyclone a richer adjustment capability, and the number of rotating switchable online adjustable bottom flow ports equipped with the cyclone can be selected at the time of sale.

[0051] Furthermore, in this embodiment, the above-mentioned rotation switch type online regulating bottom flow outlet also includes a guide clamping assembly, which can be set at the outer edge of the end of the cyclone, or at the outer edge of the first large head end 231, and can be selected according to the actual use situation. During use, when the driving assembly 21 drives the rotating member 22 to rotate, and the regulating section 23 rotates to the position of the end of the cyclone, the guide clamping assembly can guide the first large head end 231 of the regulating section 23 so that the regulating section 23 can enter the working position. At the same time, the guide clamping assembly can also press the first large head end 231 and the end of the cyclone, so that the contact surface between the first large head end 231 and the end of the cyclone fits tightly, thereby ensuring the sealing when the end of the cyclone is connected to the first large head end 231. In this way, there is no need to set a sealing structure such as a gasket between the end of the cyclone and the first large head end 231. As a new option, the end of the cyclone and the first large end 231 can be covered with wear-resistant ceramics, thereby improving the wear resistance without affecting the sealing and meeting the needs of long-term use.

[0052] The rotary switchable online adjustable bottom flow port provided in this embodiment can drive the rotating member 22 to rotate through the driving component 21, so that the adjusting section 23 on the rotating member 22 can be connected or separated with the end of the cyclone, so as to achieve online adjustment of the caliber of the bottom flow port of the cyclone to adapt to materials of different properties. The guiding and clamping component can guide the first large end 231 of the adjusting section 23 and can clamp the end of the cyclone with the first large end 231 of the adjusting section 23, so as to ensure the sealing performance when the end of the cyclone is connected with the first large end 231. Therefore, there is no need to manually set structures such as gaskets, thereby reducing manual participation. Compared with the prior art, the caliber of the bottom flow port of the cyclone can be adjusted without stopping the cyclone, thereby improving production efficiency.

[0053] It can be understood that, in this embodiment, the driving assembly 21 can also drive the rotating member 22 to rotate by means of a transmission connection with the edge of the rotating member 22 through a structure such as a gear.

[0054] The embodiment of the utility model provides a rotary switchable online regulating bottom flow outlet, such as Figure 1 , Figure 2 , Figure 3 and Figure 7As shown, a plurality of adjusting sections 23 are provided, and the first small ends 232 of all adjusting sections 23 correspond to a plurality of inner diameters, and all adjusting sections 23 are sequentially arranged on the rotating member 22 around the rotation center of the rotating member 22; the rotating member 22 is driven to rotate by the driving assembly 21, and the end of the cyclone can be selectively connected to one of the first large ends 231.

[0055] Preferably, in this embodiment, a plurality of adjusting sections 23 are provided, and the first small end 232 of all adjusting sections 23 corresponds to a plurality of different sizes of inner diameters, so that the cyclone has more discharge calibers to choose from, so as to be able to adapt to materials of different properties. Accordingly, the mounting holes on the rotating member 22 are provided in a one-to-one correspondence with the adjusting sections 23. Among them, when a plurality of adjusting sections 23 are provided, it is necessary to ensure that the inner diameters of the first large end 231 of all adjusting sections 23 are the same. So that the rotating switch type online regulating bottom flow port can be used normally.

[0056] For example, there are three adjustment sections 23, the first large end 231 of the three adjustment sections 23 has the same inner diameter, the first small end 232 corresponds to three different inner diameters, and the inner diameters of the first small end 232 of the three adjustment sections 23 decrease in sequence. Alternatively, there are three adjustment sections 23, the first large end 231 of the three adjustment sections 23 has the same inner diameter, and the first small end 232 corresponds to two different inner diameters, that is, the inner diameters of the first small end 232 of two adjustment sections 23 are the same, and the inner diameter of the first small end 232 of another adjustment section 23 is different from the inner diameters of the first small end 232 of the two adjustment sections 23. Among the two adjustment sections 23 with the same inner diameter of the first small end 232, one of the adjustment sections 23 can be used as a spare adjustment section 23; or, as mentioned above, the interior of the adjustment section 23 is a conical structure, and the two adjustment sections 23 with the same inner diameter of the first small end 232 can also have different inner cone angles, so as to adapt to materials of different properties.

[0057] Furthermore, in this embodiment, all the adjustment sections 23 are arranged in sequence along the rotation center of the rotating member 22, and two adjacent adjustment sections 23 are arranged at intervals to avoid interference between the two adjacent adjustment sections 23 when in use. The distance from the center of any adjustment section 23 to the rotation center of the rotating member 22 is the same, so that when the driving assembly 21 drives the rotating member 22 to rotate, the first large end 231 of one of the adjustment sections 23 can be connected to the end of the cyclone, thereby adjusting the diameter of the cyclone bottom flow port.

[0058] The embodiment of the utility model provides a rotary switchable online regulating bottom flow outlet, such as Figure 4 , Figure 6 and Figure 8As shown, the guide and clamping assembly is arranged at the outer edge of the end of the cyclone; the outer edge of the first large head end 231 is provided with a first flange 233, and the outer edge of the end of the cyclone is also provided with a second flange 111; when the first large head end 231 moves to the end of the cyclone, the guide and clamping assembly is used to guide the first flange 233 and to clamp the first flange 233 and the second flange 111.

[0059] Preferably, in this embodiment, the above-mentioned clamping guide assembly is arranged at the outer edge of the end of the cyclone. When multiple adjustment sections 23 are provided, if a guide clamping assembly is provided on each adjustment section 23, it will lead to excessive cost. Therefore, the guide clamping assembly is arranged at the outer edge of the end of the cyclone. The first flange 233 surrounds the peripheral side of the first large head end 231. The first flange 233 can be formed by turning the edge of the first large head end 231 outward, or it can be a flange welded to the first large head end 231. The latter is preferably used in this embodiment. Similarly, the second flange 111 is a flange welded at the end of the cyclone. The guide clamping assembly guides the first large head end 231, specifically guides the first flange 233. The guide clamping assembly presses the first flange 233 and the second flange 111, thereby eliminating the gap between the first flange 233 and the second flange 111, so that the first flange 233 and the second flange 111 can fit together, thereby achieving a seal between the end of the cyclone and the first large head end 231.

[0060] In this embodiment, by setting the first flange 233 and the second flange 111 to cooperate with the above-mentioned guide clamping assembly, the structure is simple and the clamping is convenient. In addition, there is a larger contact surface between the first flange 233 and the second flange 111, so that the sealing effect after clamping is better.

[0061] It can be understood that in this embodiment, a groove that cooperates with the roller 244 in the guide and clamping assembly can be provided on the outer wall of the adjusting section 23, so that the adjusting section 23 can be guided to enter the working position, and the first large head end 231 and the end of the cyclone can be pressed together by the guide and clamping assembly to ensure the sealing purpose between the end of the cyclone and the first large head end 231.

[0062] The embodiment of the utility model provides a rotary switchable online regulating bottom flow outlet, such as Figure 4 , Figure 6 and Figure 8 As shown, the guiding and clamping assembly includes a mounting member 241, a mounting shaft 243 and a roller 244; the mounting member 241 is arranged on the outer edge of the end of the cyclone; one end of the mounting shaft 243 is rotatably connected to the roller 244, and the other end is connected to the mounting member 241, and a guiding and clamping space 245 for guiding and clamping the first flange 233 is formed between the roller 244 and the second flange 111.

[0063] Furthermore, in the present embodiment, the guide and clamping assembly includes a mounting member 241, a mounting shaft 243 and a roller 244. The roller 244 is rotatably mounted on one end of the mounting shaft 243, and the other end of the mounting shaft 243 is connected to the outer edge of the end of the cyclone through the mounting member 241. The mounting member 241 can be a plate-like structure, or a hollow frame, etc. A guide space for guiding and clamping the first flange 233 is formed between the wheel surface of the roller 244 and the second flange 111. Due to the rotation setting of the roller 244, the first flange 233 can smoothly enter the guide and clamping space 245. The minimum distance dimension between the wheel surface of the roller 244 and the second flange 111 is the thickness dimension of the first flange 233, so that the roller 244 can press the first flange 233 and the second flange 111.

[0064] It is understandable that in this embodiment, the guiding and pressing assembly can also use a pressing block for guiding and pressing. When a pressing block is used, arc-shaped guiding surfaces are preferably provided at both ends of the pressing block so that the first flange 233 can smoothly enter the guiding and pressing space 245.

[0065] Optionally, in this embodiment, the end of the mounting shaft 243 away from the roller 244 can be connected to the mounting member 241 by conventional fixing methods such as welding and bolt connection.

[0066] Preferably, in this embodiment, the mounting member 241 and the second flange 111 are integrally formed, so that there is no need to provide a connection structure connected to the mounting member 241 on the outer edge of the end of the cyclone, thereby improving the integrity of the device.

[0067] The embodiment of the utility model provides a rotary switchable online regulating bottom flow outlet, such as Fig. 9 As shown, a sliding portion 242 is provided on the mounting member 241 ; one end of the mounting shaft 243 away from the roller 244 is connected to the sliding portion 242 , and the mounting shaft 243 can slide towards or away from the second flange 111 under the action of the sliding portion 242 .

[0068] Preferably, in this embodiment, the mounting shaft 243 is slidably disposed on the mounting member 241, and the sliding direction of the mounting shaft 243 is to slide toward or away from the second flange 111. That is, by sliding the mounting shaft 243, the size of the guide pressing space 245 can be changed to adapt to first flanges 233 of different specifications, thereby improving applicability.

[0069] The embodiment of the utility model provides a rotary switchable online regulating bottom flow outlet, such as Fig. 9 As shown, the sliding portion 242 is a waist-shaped hole provided on the mounting member 241, and one end of the mounting shaft 243 is slidably connected in the waist-shaped hole.

[0070] Specifically, in this embodiment, the sliding portion 242 is a waist-shaped hole opened on the mounting member 241, which has a simple structure, is easy to process, and has high reliability. Preferably, the extending direction of the waist-shaped hole is parallel to the axial direction of the end of the cyclone.

[0071] Further, in this embodiment, the end of the installation shaft 243 away from the roller 244 has a threaded section, and the installation shaft 243 is locked in the waist-shaped hole through the threaded end and two spaced nuts. When in use, the position of the installation shaft 243 can be adjusted by loosening the nuts.

[0072] It can be understood that, in this embodiment, the sliding portion 242 can also be a sliding groove provided on the mounting member 241, which can also achieve the purpose of adjusting the size between the roller 244 and the second flange 111 in this embodiment.

[0073] The embodiment of the utility model provides a rotary switchable online regulating bottom flow outlet, such as Figures 3 to 6 As shown, two groups of guide and clamping assemblies are provided, and the two groups of guide and clamping assemblies are arranged opposite to each other.

[0074] Preferably, in the present embodiment, two groups of guide and clamping assemblies are provided to improve the guiding effect of the guide and clamping assemblies, and to make the force on the first flange 233 more uniform, thereby improving the sealing effect.

[0075] Optionally, in this embodiment, a plurality of waist-shaped holes may be provided on each mounting member 241, a mounting shaft 243 may be installed in each waist-shaped hole, and a roller 244 may be provided on each mounting shaft 243, so as to further improve the guiding effect and the clamping effect on the first flange 233 and the second flange 111, and improve the sealing between the end of the cyclone and the first large head end 231.

[0076] The embodiment of the utility model provides a rotary switchable online regulating bottom flow outlet, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 8 and Fig. 9 As shown, a connecting section 12 is provided at the end of the cyclone; a bracket 13 is provided on the connecting section 12, and a driving assembly 21 is arranged on the bracket 13; the connecting section 12 has a second large head end 121 and a second small head end 122; the second large head end 121 is connected to the end of the cyclone, and the second small head end 122 is arranged corresponding to the first large head end 231; the guide clamping assembly and the second flange 111 are both arranged at the outer edge of the second small head end 122.

[0077] In this embodiment, a connecting section 12 is provided at the end of the cyclone, and the connecting section 12 is used to install the above-mentioned drive assembly 21. Specifically, the connecting section 12 has a second large head end 121 and a second small head end 122. The second large head end 121 is connected to the end of the cyclone, and the inner diameter of the second small head end 122 is the same as the inner diameter of the first large head end 231. When the adjustment section 23 is switched, the first large head end 231 is connected to the second small head end 122. Correspondingly, the guide clamping assembly and the second flange 111 are both arranged on the outer edge of the second small head end 122. A bracket 13 is provided on the connecting section 12, and a bearing and a bearing seat are provided on the bracket 13, and the output shaft of the drive assembly 21 is passed through the bearing.

[0078] The rotary switchable online adjustable bottom flow outlet used in this embodiment adopts a rotary cut-in adjustment method. Even if there is a mixture of liquid and coal powder attached to the joint surface (the end surface of the second small head end 122 and the end surface of the first large head end 231 and the first flange 233 and the second flange 111), it can be cleaned up by the cut-in adjustment section 23. Smooth online replacement can be achieved. There is no need to worry about leakage or getting stuck during rotation. The online replacement feature of the bottom flow outlet can realize the linkage between the cyclone and the front-end coal quality detection equipment when the quality of the raw coal changes, ensuring that the quality of the sorted product is not affected by the fluctuation of the raw coal quality, and the qualified rate of the product is always guaranteed.

[0079] The present invention also provides a cyclone, including the rotary switchable online adjustable bottom flow port described in any of the above embodiments. The cyclone includes all the advantages of the rotary switchable online adjustable bottom flow port, so they are not described here.
