Description

Technical Field

[0001] This invention relates to the field of heavy medium cyclone technology, and more specifically, to a monitoring device and a heavy medium cyclone. Background Technology

[0002] Heavy media hydrocyclones are important screening devices in industry, especially for coal screening. A heavy media hydrocyclone includes a feed inlet, an overflow outlet, and a slag discharge outlet. Because the heavy media hydrocyclone is a closed structure, during the separation process, materials and suspensions are fed tangentially into the hydrocyclone at a certain pressure, forming a strong vortex flow. The liquid flow starts from the feed inlet and forms a descending outer spiral flow along the inner wall of the hydrocyclone. Near the axis of the hydrocyclone, an ascending inner spiral flow forms. Due to the negative pressure of the inner spiral flow, air is drawn in, forming an air column at the axis of the hydrocyclone. The clean coal in the feed flows upward with the inner spiral flow and is discharged from the overflow outlet, while the gangue flows downward with the outer spiral flow and is discharged from the bottom slag discharge outlet.

[0003] However, existing heavy medium hydrocyclones cannot monitor their operating status during operation, especially during coal screening. Clean coal flows out of the overflow port, but the quality of the clean coal can only be monitored after it flows out, which is slow and cannot achieve real-time monitoring of the hydrocyclone.

The housing 21 includes a transparent plate segment 211 made of transparent material; and a camera component 30, whose camera head is positioned facing the transparent plate segment 211 to take pictures of the material in the buffer cavity 22.

[0038] The monitoring device of the present invention includes a buffer component 20 and a camera component 30. The buffer component 20 includes a housing 21, which has a buffer cavity 22 and a second overflow port 23. After the material flows out of the first overflow port 11 of the hydrocyclone body 10, it can enter the buffer cavity 22 and then flow out of the second overflow port 23 of the housing 21. When the material flows through the buffer cavity 22, the camera component 30 can take pictures of the material in the buffer cavity 22 through the transparent plate segment 211 at any time. Therefore, the screening status of the material in the hydrocyclone body 10 can be obtained in real time. At the same time, the buffer cavity 22 can slow down the flow rate of the material, which makes it easier for the camera component 30 to take pictures of the inside of the buffer cavity 22 and clearly observe the material inside the buffer cavity 22. Thus, the monitoring device of the present invention solves the problem that the existing technology cannot monitor the working status of heavy medium hydrocyclones in real time.

[0039] Specifically, the buffer chamber 22 is a cylindrical structure, the top surface of the buffer chamber 22 is a transparent plate segment 211, and the bottom of the buffer chamber 22 is connected to the first overflow port 11 of the hydrocyclone body.

This arrangement allows for comprehensive imaging of materials at multiple locations within the buffer chamber 22, ensuring monitoring accuracy.

[0043] Specifically, a mounting plate 40 is fixedly installed on the upper part of the buffer 20, and multiple camera components 30 are evenly distributed on the mounting plate, so that the material in multiple positions inside the buffer cavity 22 can be captured comprehensively.

[0044] Optionally, there are four camera components 30, with a 90-degree interval between adjacent camera components 30.

[0045] In this embodiment, the monitoring device further includes: a mounting plate 40, which is rotatably connected to the buffer member 20; and a camera component 30 disposed on the mounting plate 40 so that the camera component 30 can take pictures of different positions within the buffer cavity 22.

[0046] Specifically, the mounting plate 40 is rotatably mounted on the upper part of the buffer component 20, and the camera component 30 is rotatably mounted to take pictures of different positions inside the buffer cavity 22, so that the flowing material inside the buffer cavity 22 can be captured from all angles, thereby improving the randomness and accuracy of the shooting by the camera component 30 and avoiding the error caused by a single position in the picture.

[0047] In this embodiment, a limiting ring 24 is provided on the buffer member 20, and the shape of the mounting plate 40 is adapted to the shape of the limiting ring 24. The mounting plate 40 is rotatably disposed within the limiting ring 24. And / or, the monitoring device further includes a first driving member 50 and a first gear 60. The first driving member 50 is disposed on the buffer member 20, and the first driving member 50 is drivenly connected to the first gear 60. The first gear 60 meshes with the gear teeth 41 on the mounting plate 40, so that the first driving member 50 drives the mounting plate 40 to rotate through the first gear 60 and the gear teeth 41.

[0048] Specifically, the limiting ring 24 is arranged in a ring and fixedly installed at the upper edge of the buffer 20. The bottom outer side of the mounting plate 40 contacts the inner sidewall of the limiting ring 24, and the mounting plate 40 can rotate inside the limiting ring 24. A first driving member 50 is fixedly installed on the outer sidewall of the buffer 20. The first driving member 50 can drive the first gear 60 to rotate. The first gear 60 drives the mounting plate 40 to rotate by driving the gear teeth 41 on the mounting plate 40 to rotate. The rotation of the mounting plate 40 drives the camera component 30 to rotate.

[0049] Optionally, the first driving component 50 is a motor.

[0050] In this embodiment, the buffer 20 is used to support the hydrocyclone body 10 and is rotatably disposed relative to the hydrocyclone body 10; the monitoring device also includes a second drive 70, a second gear 80 and a third gear 90, the second drive 70 is drivenly connected to the second gear 80, the second gear 80 is meshed with the third gear 90, and the third gear 90 is fixedly connected to the buffer 20, so that the second drive 70 drives the buffer 20 to rotate through the second gear 80 and the third gear 90, so that the camera component 30 rotates synchronously with the buffer 20.

[0051] Specifically, the buffer 20 is rotatably connected to the upper end of the hydrocyclone body 10. The edge of the first overflow port 11 of the hydrocyclone body 10 has an outwardly protruding structure. The bottom of the buffer 20 is installed with the protruding structure and can rotate at the first overflow port 11. A third gear 90 is fixedly installed at the bottom of the buffer 20. A second drive 70 is fixedly installed on the top side of one side of the hydrocyclone body 10. The second drive 70 drives the second gear 80 to rotate. The second gear 80 drives the third gear 90 to rotate, thereby driving the buffer 20 to rotate. During the rotation of the buffer 20, the mounting plate 40 and the camera component 30 can rotate synchronously, so that the camera component can take pictures while moving, avoiding errors caused by a single position. The mounting plate 40 is fixedly installed on the top of the buffer 20; or, the mounting plate 40 is rotatably installed on the top of the buffer 20.

[0052] It should be noted that, in addition to being rotatably connected to the upper end of the hydrocyclone body 10, the buffer 20 can also be fixedly connected to the hydrocyclone body 10.

[0053] Optionally, the second drive component 70 is a motor.

[0054] In this embodiment, the monitoring device further includes: an overflow pipe 100, which is connected to the housing 21 and communicates with the second overflow port 23; a bypass pipe 110, the first end of which is connected to the housing 21 and communicates with the buffer chamber 22, and the second end of which is connected to the wall of the overflow pipe 100 and communicates with the overflow pipe 100; a first valve 120, which is disposed on the bypass pipe 110 to control the opening and closing of the bypass pipe 110; and a second valve 130, which is disposed on the bypass pipe 110 and located on the side of the first valve 120 away from the housing 21, and controls the opening and closing of the bypass pipe 110; wherein, the bypass pipe 110 is provided with a discharge port 111 for allowing material to flow out, and the discharge port 111 is located between the first valve 120 and the second valve 130.

[0055] In practice, during the operation of the hydrocyclone, the material in the overflow pipe 100 also needs to be monitored. The two ends of the bypass pipe 110 are connected to the buffer chamber 22 and the overflow pipe 100, respectively. When using the bypass pipe 110, firstly, the first valve 120 is opened to allow the material in the buffer chamber 22 to enter the bypass pipe 110. Then, the second valve 130 is opened to allow the material in the bypass pipe 110 to enter the overflow pipe 100. After both valves have been open for 5-10 minutes, first, the first valve 120 is closed, and then the second valve 130 is closed, thus allowing the material to remain in the bypass pipe 110. Additionally, the material can flow out from the discharge port 111.

[0056] Specifically, an overflow pipe 100 is installed at the upper center of the buffer 20, and the overflow pipe 100 extends to the outside through the mounting plate 40. The material in the buffer cavity 22 will flow out from the overflow pipe 100.

[0057] In this embodiment, the monitoring device further includes: a door panel 140, which is movably connected to the bypass pipe 110 to open and close the discharge port 111; and / or a support portion 150, which is connected to the wall of the bypass pipe 110, with at least a portion of the support portion 150 disposed below the discharge port 111 to receive the material flowing out of the discharge port 111.

[0058] Specifically, the door panel 140 includes a first plate segment and a second plate segment connected to the first plate segment. The first plate segment is inclined relative to the second plate segment. The first plate segment is detachably connected to the bypass pipe 110 so that the second plate segment can open and close the discharge port 111. The first plate segment is provided with a first fastening hole, and the bypass pipe 110 is provided with a second fastening hole. The door panel 140 is fixedly installed on the bypass pipe 110 by fasteners inserted into the first and second fastening holes. When the fasteners are removed and the door panel 140 is removed, the second plate segment opens the discharge port 111, and the material in the bypass pipe 110 flows out from the discharge port 111 into the support part 150. The experimenter can hold the material in the support part 150 to test the material. Moreover, during the testing process and during the entire use of the bypass pipe 110, the hydrocyclone body 10 does not stop working.

[0059] Optionally, the door panel 140 has an L-shaped structure and bolts are used as fasteners.

[0060] In this embodiment, the door panel 140 is detachably connected to the bypass pipe 110; the bypass pipe 110 is provided with a first limiting plate 112 and a second limiting plate 113 on its pipe wall, the first limiting plate 112 and the second limiting plate 113 are provided on opposite sides of the discharge port 111, the first limiting plate 112 has a limiting hole, and the door panel 140 passes through the limiting hole; the second limiting plate 113 is provided with a groove, and one end of the door panel 140 passes through the limiting hole and is inserted into the groove to close the discharge port 111.

[0061] Specifically, a first limiting plate 112 and a second limiting plate 113 are respectively installed at the upper end and the bottom of the discharge port 111. When the fasteners are tightened to fix the door panel 140 on the bypass pipe 110, the second plate segment of the door panel 140 passes through the limiting hole of the first limiting plate 112, and the bottom of the second plate segment is inserted into the groove on the second limiting plate 113 that matches the bottom of the second plate segment, so as to prevent the door panel 140 from sliding and causing material leakage in the bypass pipe 110.

[0062] In this embodiment, a spiral blade is provided on the inner wall of the housing 21, and the spiral blade is spirally arranged in the direction from the first overflow port 11 to the second overflow port 23.

[0063] Specifically, during the rotation of the buffer chamber 22, the spiral blades can push the material in the buffer chamber 22 to flow from the first overflow port 11 to the second overflow port 23 and enter the overflow pipe 100, making it easier for the material to overflow. Moreover, the material is pushed by the spiral blades, and the amount of material in the photo is relatively stable when the camera component 30 takes a picture.

[0064] Optionally, the minimum distance between the spiral blades is greater than the maximum diameter of the material that the hydrocyclone body can screen, so that all the material in the buffer chamber 22 can move and avoid dead zones.

[0065] In other embodiments, the monitoring device further includes: a baffle 160 disposed in the buffer cavity 22, the baffle 160 being spaced apart from the first overflow port 11 and the second overflow port 23 respectively; the baffle 160 having a first end face and a second end face disposed opposite to each other, at least a portion of the first end face being disposed opposite to the first overflow port 11, and at least a portion of the second end face being disposed opposite to the second overflow port 23.

[0066] Specifically, when the material flows out of the first overflow port 11, it also undergoes a spiral motion, thus entering the buffer chamber 22. Under the action of the baffle 160, the material flows to both sides, reaching the edge of the buffer chamber 22. This allows the material to flow throughout the entire buffer chamber 22, ensuring that all the material in the buffer chamber can move and avoiding dead zones. Especially during photography, the distribution of the flowing material is more uniform, resulting in more accurate photos taken by the camera component 30.

[0067] Optionally, the minimum distance between the baffle 160 and the side wall of the buffer chamber 22 is greater than the maximum diameter of the material that the hydrocyclone body can screen, so that all the material in the buffer chamber 22 can move and avoid dead zones.

[0068] Optionally, the baffle 160 is a circular plate; or, the baffle 160 includes a first baffle 162, the first baffle 162 being conical in shape, and the diameter of the first baffle 162 gradually increasing from the first overflow port 11 to the second overflow port 23; or, the baffle 160 includes a first baffle 162 and a second baffle 163, the second baffle 163 being located on the side of the first baffle 162 away from the first overflow port 11, both the first baffle 162 and the second baffle 163 being conical in shape, and the large-diameter ends of the first baffle 162 and the second baffle 163 being connected; the diameter of the first baffle 162 gradually increasing and the diameter of the second baffle 163 gradually decreasing from the first overflow port 11 to the second overflow port 23.

[0069] Specifically, such as Figure 4As shown, when the baffle 160 includes a conical first baffle 162 and a conical second baffle 163, the second baffle 163 allows the material at the bottom to move to both sides of the buffer cavity 22, and the first baffle 162 allows the material at the top to move towards the overflow pipe 100, so that the material passes through the entire buffer cavity 22 evenly without dead corners. The material moving in all directions makes the material distribution in each picture more even, avoiding inaccurate shooting due to the material piling up in the dead corners of the buffer cavity 22, and also helps the material to be discharged from the overflow pipe 100.

[0070] Specifically, the monitoring device also includes a first connector 170, which is disposed in the buffer cavity 22. The first end of the first connector 170 is used to connect with the hydrocyclone body 10, and the second end of the first connector 170 is connected with the first end face of the baffle 160.

[0071] In specific implementation, a first connector 170 is fixedly installed on the first end face of the baffle 160. The bottom of the first connector 170 is connected to the hydrocyclone body 10 so as to support the baffle 160 through the first connector 170 and realize the connection between the baffle 160 and the hydrocyclone body 10. The first connector 170 is set in an inverted outward V-shape.

[0072] Specifically, a first guide groove is provided on the first end face, and a first rotating ring 171 is provided on the second end of the first connector 170. The first rotating ring 171 is rotatably disposed in the first guide groove so that the baffle 160 is rotatably disposed relative to the first connector 170. A first guide plate 161 is also provided on the first end face, and the first guide plate 161 protrudes from the first end face.

[0073] In specific implementation, a first guide groove is provided on the outer side of the first end face of the baffle 160, and a first rotating ring 171 is rotatably installed inside the first guide groove. The first rotating ring 171 is fixedly connected to the first connecting member 170, and the baffle 160 can rotate relative to the first connecting member 170. A first guide plate 161 is fixedly installed on the outer side of the first end face of the baffle 160. When the material flows out of the first overflow port 11, it will rotate spirally. When it passes through the first guide plate 161, it will carry the baffle 160 to rotate, thereby making the material pass through the entire buffer cavity 22 more evenly. The material moving throughout the entire cavity makes the material distribution in each picture more even, avoiding inaccurate shooting due to the accumulation of material in the dead corners of the buffer cavity 22. Of course, the baffle 160 can also be fixedly connected to the first connecting member 170.

[0074] Optionally, the first guide groove is an annular groove, the first guide plate 161 is conical, the first guide plate 161 is a flat plate, and the flat plate is in the vertical direction; of course, the first guide plate 161 can also be set as an arc plate or other structures that allow the material to rotate with the baffle 160 when passing through the first guide plate 161, depending on the actual use requirements.

[0075] Specifically, a second guide groove is provided on the second end face; the monitoring device also includes a second connector 180, the first end of the second connector 180 is connected to the housing 21, the second end of the second connector 180 is provided with a second rotating ring 181, the second rotating ring 181 is rotatably disposed in the second guide groove so that the baffle 160 is rotatably disposed relative to the second connector 180; and / or, a second guide plate 182 is provided on the second end face, the second guide plate 182 protruding from the second end face.

[0076] In specific implementation, a second guide groove is provided on the outer side of the second end face of the baffle 160. A second rotating ring 181 is rotatably installed inside the second guide groove. The second rotating ring 181 is fixedly connected to the second connecting member 180. The second connecting member 180 is arranged in an outward V-shape, and its top is connected to the housing 21 to realize the fixed connection between the second rotating ring 181 and the housing 21. The baffle 160 can rotate relative to the second connecting member 180. A second guide plate 182 is provided on the second end face of the baffle 160. When the material flows out from the first overflow port 11, it will rotate spirally. When it passes through the first guide plate 161, it will drive the baffle 160 to rotate, which in turn drives the second guide plate 182 to rotate. During the rotation, the second guide plate 182 will carry the material in the upper part of the buffer cavity upward, thereby entering the overflow pipe 100 and being discharged from the overflow pipe 100.

[0077] Optionally, the second guide groove is an annular groove, the second guide plate 182 is conical, or the second guide plate 182 is an arc-shaped plate.

[0078] In this embodiment, the housing 21 includes a top plate 212 and a bottom plate 213. The bottom plate 213 is connected to the hydrocyclone body 10, and its opening communicates with the first overflow port 11. The top plate 212 has a second overflow port 23. Both the top plate 212 and the bottom plate 213 are frustum-shaped. From the first overflow port 11 to the second overflow port 23, the cross-sectional area of ​​the cavity formed by the bottom plate 213 gradually increases, while the cross-sectional area of ​​the cavity formed by the top plate 212 gradually decreases. This arrangement avoids dead corners in the buffer cavity and facilitates the discharge of material from the overflow pipe. In addition, when photographing materials in full motion, the coal blocks in each photograph are more evenly distributed, avoiding inaccurate photographs caused by coal blocks piling up in dead corners of the buffer cavity.

[0079] Specifically, the shell 21 has a buffer chamber 22. The material flows into the buffer chamber 22 after passing through the opening of the first overflow port 11 and the bottom plate 213 from the hydrocyclone body 10. The rotation force of the material flowing out of the hydrocyclone body 10 will gradually decrease, and the distribution area in the buffer chamber 22 will gradually increase and then gradually decrease. Then the material flows out of the buffer chamber through the second overflow port 23 of the top plate 212. The frustum-shaped top plate 212 and bottom plate 213 are more in line with the material's running distribution.

[0080] Specifically, the top plate 212 and bottom plate 213 of the buffer chamber 22 are respectively configured to be parallel to the second baffle 163 and the first baffle 162. During the rotation of the baffle, the material at the bottom can move to the bottom sides of the buffer chamber, while the material at the top of the buffer chamber will move towards the overflow pipe, allowing the material to pass through the entire buffer chamber, avoiding dead corners in the buffer chamber, and facilitating the discharge of material in the overflow pipe. In addition, when taking pictures of the material moving in all directions, the coal blocks in each picture are more evenly distributed, avoiding inaccurate pictures caused by coal blocks piling up in the dead corners of the buffer chamber. In this embodiment, the monitoring device further includes an overflow pipe 100, which is connected to the housing 21 and communicates with the second overflow port 23. At least a portion of the overflow pipe 100 is an adjusting pipe, which includes: an inner pipe 101, which has a first free end and a second free end disposed opposite to each other along its circumferential direction. The first free end and the second free end are stacked on top of each other. When the inner pipe 101 is squeezed, the first free end and the second free end move along the circumferential direction of the inner pipe 101 to change the inner diameter of the inner pipe 101; an outer pipe 102, which is sleeved on the inner pipe 101 and is made of an elastic material; and a strap 103, which is sleeved on the outer pipe 102 to squeeze the outer pipe 102 and the inner pipe 101 by tightening the strap 103.

[0081] Specifically, the regulating tube includes an inner pipe 101 and an outer pipe 102 sleeved on the outside of the inner pipe. Reducing the diameter of the regulating tube decreases the actual screening density, while increasing the diameter increases the actual screening density. When the inner pipe 101 is compressed, its first and second free ends can be compressed and rolled inwards, changing its diameter and thus the diameter of the regulating tube, thereby adjusting both the diameter and screening density. A strap 103 is installed on the outside of the outer pipe 102, and multiple evenly distributed retaining rings 106 are fixedly installed on the outside of the outer pipe 102. The strap 103 is located between the retaining rings 106 and the outer pipe 102, connecting them together. The strap 103 can slide within the retaining rings 106. When the strap 103 tightens, it compresses both the outer pipe 102 and the inner pipe 101, causing the inner pipe 101 to roll inwards to reduce its diameter, thus reducing the diameter of the regulating tube and lowering the actual screening density.

[0082] Optionally, the inner pipe 101 is made of elastic steel or high-hardness, high-plasticity plastic material, which has sufficient elasticity; the outer pipe 102 is made of silicone, plastic or rubber material, which is relatively soft and can squeeze the side walls of the outer pipe 102 together when squeezed, thereby changing the diameter of the outer pipe 102; the strap 103 is a metal strip structure.

[0083] In practice, the camera component 30 can take pictures of the interior of the buffer cavity 22 through the transparent plate segment 211. The distance between the camera component 30 and the transparent plate segment 211 remains unchanged. After adjusting the pixels of the transparent plate segment 211, the length and width of the picture taken by the transparent plate segment 211 are fixed, that is, the area captured by the transparent plate segment 211 is fixed.

[0084] In practice, during the operation of the hydrocyclone body 10, the content of clean coal, middlings, and gangue in the raw material entering through the feed inlet 12 remains essentially constant, and the content of clean coal in the raw material also remains essentially constant. When the hydrocyclone body 10 is operating, the amount of clean coal selected by the second overflow outlet 23 remains relatively stable; that is, when clean coal flows out of the first overflow outlet 11, the content of clean coal and medium remains relatively stable. After the camera component 30 takes a picture, it will capture the amount of clean coal entering in a relatively stable quantity in each picture. At this time, each picture is used as a unit module for comparison. When the amount of coal flowing out of the first overflow outlet 11 suddenly changes, taking an increase in the amount of coal as an example: when the amount of coal flowing out of the first overflow outlet 11 suddenly increases, the number of coal chunks in the buffer chamber 22 will suddenly increase, and the number of coal chunks in the picture taken by the camera component 30 will also suddenly increase. By comparing with the amount of coal in the picture, a sudden increase in quantity indicates that there is a problem with the operation of the hydrocyclone body 10. Since the raw material at the feed inlet 12 remains relatively stable, there will be no sudden increase in the number of coal blocks at the first overflow port 11 of the hydrocyclone body 10. Therefore, the cause may be that the pressure is too high, causing middlings to enter the first overflow port 11, or that the bottom outlet at the bottom of the hydrocyclone body 10 is blocked, resulting in an increase in the amount of coal at the first overflow port 11.

[0085] In this embodiment, a T-shaped groove 104 with an annular structure is provided on the outer side of the inner pipe 101, such as... Figure 8As shown, multiple evenly distributed sliders 105 are fixedly installed inside the outer pipe 102. The sliders 105 are installed in the T-shaped groove 104 and can slide within the T-shaped groove 104. When the inner pipe 101 is squeezed, the diameter of the inner pipe 101 decreases. Since the outer pipe 102 is connected to the inner pipe 101 through the sliders 105, except at the connection point, the other parts of the outer pipe 102 expand outward to form a wave-like structure, thus reducing the diameter of the outer pipe 102. The outer pipe 102 is installed on the overflow pipe body of the overflow pipe 100, and both ends of the outer pipe 102 are fixedly connected to the overflow pipe body. The outer pipe 102 has a sealing function. The two ends of the outer pipe 102 are made of a relatively thick elastic material, which can withstand sufficient pressure and friction and can also undergo a certain degree of deformation. Since the inner pipe 101 and the outer pipe 102 are connected by sliders 105 and grooves, the outer pipe 102 can deform when squeezed, and the two do not affect each other.

[0086] In this embodiment, a connecting ring is fixedly installed at one end of the strap 103, and the other end of the strap 103 passes through the connecting ring and can slide on the connecting ring. A semi-threaded structure is provided on the outer side of the strap 103, and a threaded post 107 that contacts the semi-thread is rotatably installed on the connecting ring. A cross-shaped groove is provided on the threaded post 107. The threaded post 107 can be rotated with a cross-shaped screwdriver. Under the action of the thread, the strap 103 can contract, squeezing the inner pipe 101 and the outer pipe 102, making the diameter of the inner pipe 101 smaller. Reverse rotation of the threaded post 107 will make the strap 103 larger, and under the action of the elasticity of the inner pipe 101, the outer pipe 102 will open, thereby increasing the pipe diameter. By adjusting the size of the inner pipe 101, the diameter of part of the overflow pipe is changed, thereby adjusting the diameter of the overflow pipe. With the first overflow port and the feed port unchanged, reducing the overflow pipe diameter reduces the actual sorting density, and increasing the overflow pipe diameter reduces the actual sorting density, thereby achieving the purpose of adjusting the screening density.

[0087] The present invention also provides a heavy medium cyclone separator, including a cyclone body 10, the cyclone body 10 having a feed inlet 12 and a first overflow outlet 11, and the heavy medium cyclone separator also includes the monitoring device in the above embodiments.

[0088] The heavy medium cyclone of the present invention includes a cyclone body 10 and a monitoring device, the monitoring device including a buffer 20 and a camera component 30. A feed inlet 12 is provided on one side of the upper end of the cyclone body 10. The feed inlet 12 is used to feed material into the interior of the cyclone body 10, so that the material moves along the tangential direction of the inner cavity of the cyclone, thereby generating centrifugal force.

[0089] Specifically, a buffer component 20 is welded and fixed to the top of the hydrocyclone body 10. The buffer component 20 includes a shell 21, which has a buffer cavity 22 and a second overflow port 23. The shell 21 is a cylindrical structure, and its top surface is a transparent plate segment 211. The bottom of the shell 21 is connected to the first overflow port 11 of the hydrocyclone body. After the material flows out of the first overflow port 11 of the hydrocyclone body 10, it can enter the buffer cavity 22 and then flow out from the second overflow port of the shell 21. When the material flows through the buffer cavity 22, the camera component 30 can take pictures of the material in the buffer cavity 22 through the transparent plate segment 211 at any time. Therefore, the screening status of the material in the hydrocyclone body 10 can be obtained in real time. At the same time, the buffer cavity 22 can slow down the flow rate of the material, making it easier for the camera component 30 to take pictures of the inside of the buffer cavity 22 and clearly observe the material inside the buffer cavity 22. Thus, the monitoring device of the present invention solves the problem that the existing technology cannot monitor the working status of heavy medium hydrocyclones in real time.

[0090] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0091] The monitoring device of the present invention includes a buffer component 20 and a camera component 30. The buffer component 20 includes a housing 21, which has a buffer cavity 22 and a second overflow port 23. After the material flows out of the first overflow port 11 of the hydrocyclone body 10, it can enter the buffer cavity 22 and then flow out of the second overflow port 23 of the housing 21. When the material flows through the buffer cavity 22, the camera component 30 can take pictures of the material in the buffer cavity 22 through the transparent plate segment 211 at any time. Therefore, the screening status of the material in the hydrocyclone body 10 can be obtained in real time. At the same time, the buffer cavity 22 can slow down the flow rate of the material, which makes it easier for the camera component 30 to take pictures of the inside of the buffer cavity 22 and clearly observe the material inside the buffer cavity 22. Thus, the monitoring device of the present invention solves the problem that the existing technology cannot monitor the working status of heavy medium hydrocyclones in real time.
