Description

Technical Field

[0001] This application belongs to the field of tar separation technology, and in particular relates to a separation device. Background Technology

[0002] Coal gas and water is a complex mixture, mainly composed of light oil, water, and dust-laden tar. Separation devices are typically used to separate the coal gas and water. The resulting light oil, water, and dust-laden tar can then be further processed and utilized, reducing environmental pollution.

[0003] Currently, gas-water separation devices typically utilize gravity settling to separate coal gas and water. The separated gas and water are stratified within the separator's tank, with dust-laden tar at the bottom. After settling, the tar adheres to the inner surface of the tank. A blade stirrer is installed at the bottom of the separator; its rotation scrapes away the adhering dust-laden tar. However, if the blade stirrer penetrates too deeply during this scraping process, it can cause motor overload or damage to the tank. Utility Model Content

[0027] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0028] like Figures 1 to 5 As shown in the figure, this application embodiment provides a separation device, which includes a separation cylinder 1, the separation cylinder 1 including a conical first separation part 11, the first separation part 11 being provided with a cleaning component 4; a drive component 2, disposed below the separation cylinder 1 along the height direction, the drive component 2 including a rotation drive mechanism 21 and a lifting drive mechanism 22; and a transmission shaft assembly 3, the rotation drive mechanism 21 and the lifting drive mechanism 22 being connected to the cleaning component 4 through the transmission shaft assembly 3, the transmission shaft assembly 3 including a first transmission shaft 31 and a second transmission shaft 32 extending along the height direction, the first transmission shaft 31 being movably connected to the second transmission shaft 32 to swing relative to the second transmission shaft 32, the first transmission shaft 31 being connected to the cleaning component 4, and the second transmission shaft 32 being connected to the drive component 2.

[0029] In this embodiment, the separation device can separate coal gas and water using gravity settling. The coal gas and water enter the separation device from the upper middle part of the separation cylinder 1, where light oil, water, and dust-laden tar are separated by density difference. The separation cylinder 1 includes a conical first separation section 11 and a cylindrical second separation section 13. Figure 1The diagram shows the specific structure of the first separation section 11 and a partial structure of the second separation section 13. The second separation section 13 is connected to the upper part of the first separation section 11. After the separation of gas and water, the water and light oil, which have lower densities, can float in the second separation section 13, while the dust-laden tar concentrates on the inner wall of the first separation section 11, thus achieving the separation of different substances in the gas and water. Furthermore, the second separation section 13 also has a gas-water inlet, a drain outlet, and an oil outlet. The gas and water can enter the separation cylinder 1 through the gas-water inlet, and the water and light oil obtained after gas-water separation can be discharged through the drain outlet and oil outlet, respectively.

[0030] In specific implementation, the separation device of this application embodiment includes a separation cylinder 1, a drive assembly 2, and a transmission shaft assembly 3. The drive assembly 2 is connected to the cleaning assembly 4 inside the separation cylinder 1 via the transmission shaft assembly 3. The rotation drive mechanism 21 in the drive assembly 2 can control the rotation of the cleaning assembly 4, thereby cleaning the conical wall surface of the first separation part 11. The lifting drive mechanism 22 of the drive assembly 2 can control the lifting of the cleaning assembly 4, thereby changing the degree of contact between the cleaning assembly 4 and the conical wall surface of the first separation part 11, and realizing the control of the overall cutting depth of the cleaning assembly 4. The first transmission shaft 31 connected to the cleaning assembly 4 can swing to control the specific cutting depth of the cleaning assembly 4 in a certain direction.

[0031] The coordinated control of the lifting and swinging of the cleaning component 4 can precisely control the cutting depth of the cleaning component 4 at any position, effectively avoiding the phenomenon of excessive cutting depth during the cleaning process. Excessive cutting depth will not only damage the inner wall surface of the separation cylinder 1, but also cause a large interaction force between the inner wall surface of the separation cylinder 1 and the cleaning component 4. After the cleaning component 4 is subjected to the reverse force, it will transmit the force to the transmission shaft assembly 3 and the drive assembly 2 in sequence, causing excessive stress at the connection of the transmission shaft assembly 3 or overload of the motor of the drive assembly 2. Therefore, the adjustable setting of the cleaning component 4 in this embodiment can avoid the separation device from malfunctioning and enable the separation device to operate stably for a long time.

[0032] Furthermore, the drive assembly 2 is located at the bottom of the separation cylinder 1. The transmission and coordination between different parts in the drive assembly 2 will not be affected by the gas and water inside the separation cylinder 1, thus preventing excessive dirt from being generated at the joints and ensuring the normal operation of the separation device as a whole, eliminating the need for frequent maintenance and cleaning. The drive assembly 2 also drives the cleaning assembly 4 through the transmission shaft assembly 3 extending along the height direction. The first transmission shaft 31 of the transmission shaft assembly 3 passes through the bottom center of the first separation part 11, thereby realizing single-axis center drive, ensuring the uniformity of rotation of the cleaning assembly 4, and avoiding problems such as overload deformation and poor uniformity of rotation of the cleaning assembly 4 caused by eccentric transmission.

[0033] like Figure 1 As shown in the separation device of this application embodiment, the second drive shaft 32 includes a first shaft segment 321 and a second shaft segment 322 arranged sequentially along the height direction. The first shaft segment 321 and the second shaft segment 322 are connected by a rigid coupling 33, and the first drive shaft 31 is connected to the first shaft segment 321 by a flexible coupling 34.

[0034] In specific implementation, the first shaft segment 321 of the second drive shaft 32 is close to the first drive shaft 31 and is connected to the first drive shaft 31 through a flexible coupling 34. The flexible coupling 34 allows the first drive shaft 31 to swing relative to the first shaft segment 321 to a certain extent, that is, there is a certain angular deviation between the axial direction of the first drive shaft 31 and the axial direction of the first shaft segment 321. Under this angular deviation, the rotation of the first shaft segment 321 can be accurately transmitted to the first drive shaft 31, ensuring that the first drive shaft 31 has sufficient rotational stability, thereby realizing the precise control of the rotation of the cleaning component 4 connected to the first drive shaft 31 by the drive component 2.

[0035] The first shaft segment 321 and the second shaft segment 322 of the second drive shaft 32 are connected by a rigid coupling 33. The second shaft segment 322 is connected to the drive assembly 2. The rigid coupling 33 ensures that the first shaft segment 321 and the second shaft segment 322 will not have axial or radial displacement or angular deviation. When the drive assembly 2 drives the second shaft segment 322 to rotate, the first shaft segment 321 can rotate stably, thereby driving the first drive shaft 31 to rotate stably, further improving the rotational stability of the cleaning assembly 4.

[0036] In some alternative embodiments, the first drive shaft 31 and the first shaft segment 321 can also be movably connected by a hinge or rotational connection. In all such connection methods, the transmission stability between the first drive shaft 31 and the first shaft segment 321 must be ensured. When the drive component 2 drives the first shaft segment 321 to rotate, the first drive shaft 31 and the first shaft segment 321 must remain fixed so that the first drive shaft 31 and the cleaning component 4 connected thereto can rotate stably.

[0037] like Figure 1 As shown in the embodiment of the present application, in the separation device, at least a portion of the first shaft segment 321 passes through the separation cylinder 1 and is connected to the first drive shaft 31, and the first shaft segment 321 is sealed to the separation cylinder 1 through the sealing structure 35.

[0038] In specific implementation, at least a portion of the first shaft segment 321 is inserted into the separation cylinder 1, which ensures that the connection between the first shaft segment 321 and the first drive shaft 31 can be located inside the separation cylinder 1. In this way, when the first drive shaft 31 swings relative to the first shaft segment 321, it can drive the cleaning component 4 to swing inside the separation cylinder 1, rather than driving the separation cylinder 1 as a whole to swing, thereby realizing the adjustment of the swing angle of the cleaning component 4 inside the separation cylinder 1.

[0039] The first shaft section 321 enters the separation cylinder 1 through an opening at the bottom of the separation cylinder 1, and the opening is sealed by a sealing structure 35, thereby achieving a sealed connection between the first shaft section 321 and the separation cylinder 1. The sealing structure 35 prevents dust-laden tar from flowing out of the separation cylinder 1 along the outer surface of the first shaft section 321, thus avoiding contamination of the drive assembly 2 at the bottom.

[0040] Specifically, such as Figure 1 As shown, the separating cylinder 1 also includes a collecting section 14, which is cylindrical in shape and located at the bottom of the first separating section 11, communicating with it. After the cleaning component 4 scrapes away the dust-laden tar in the first separating section 11, the dust-laden tar flows into the collecting section 14 under gravity, where it is collected and discharged. The bottom opening of the separating cylinder 1 is located at the bottom of the collecting section 14, and the first shaft section 321 is sealed to the collecting section 14 via a sealing structure 35.

[0041] In the separation device of this application embodiment, the first drive shaft 31 has a swing angle A relative to the extending direction of the second drive shaft 32, wherein 0°≤A≤1°. It should be noted that the first drive shaft 31 swings in any direction, and its swing angle A is always greater than 0°, and its swing angle A has no negative value.

[0042] In practical implementation, within the swing angle A range, the first drive shaft 31 can swing relative to the second drive shaft 32 by a small amplitude of less than or equal to 1°. This allows for fine-tuning of the angle of the first drive shaft 31, thereby slightly changing the cutting depth of the cleaning component 4 and preventing damage to the separation device due to excessive cutting depth. Specifically, there is a linear relationship between the swing angle A of the first drive shaft 31 and the cutting depth of the cleaning component 4; when the swing angle A is 1°, the cutting depth of the cleaning component 4 increases by 37mm.

[0043] like Figures 1 to 3 As shown in the separation device of this application embodiment, the cleaning component 4 includes a support structure 41 and a plurality of cleaning structures 42. The support structure 41 has a conical structure, and the plurality of cleaning structures 42 are evenly spaced and connected to the outer periphery of the support structure 41 along the circumference of the support structure 41.

[0044] In specific implementation, the support structure 41 of the cleaning component 4 is conical, so that the multiple cleaning structures 42 arranged on its outer periphery can be arranged in a conical structure, and the multiple cleaning structures 42 can clean the conical wall of the first separation part 11 in a conical shape, thereby achieving sufficient cleaning of the inner wall of the first separation part 11 and avoiding the residue of dust and tar.

[0045] like Figure 3 and Figure 4 As shown in the separation device of this application embodiment, each cleaning structure 42 includes a connecting rod 421 and a plurality of cleaning parts 422. The connecting rod 421 extends from the top to the bottom of the support structure 41, and the plurality of cleaning parts 422 are spaced apart along the extension direction of the corresponding connecting rod 421 on the side of the connecting rod 421 facing the first separation part 11.

[0046] In specific implementation, multiple connecting rods 421 are spaced apart on the outer periphery of the support structure 41, and each connecting rod 421 extends from the top to the bottom of the support structure 41 to form a conical structure. Multiple cleaning parts 422 are provided on the side of each connecting rod 421 facing the inner wall of the first separation part 11. The cleaning parts 422 clean the inner wall of the first separation part 11 when the cleaning component 4 moves. The protrusion of the connecting rods 421 ensures sufficient cutting depth and improves the cleaning effect on the first separation part 11.

[0047] Specifically, the support structure 41 has a conical structure. When the cleaning component 4 rotates, the multiple cleaning structures 42 connected to the outer periphery of the support structure 41 can rotate and form a conical cleaning surface, thereby further improving the cleaning effect on the conical wall surface of the first separation part 11.

[0048] Specifically, the support structure 41 includes multiple first support rods 411, multiple second support rods 412, and three annular connecting parts 413. Two annular connecting parts 413 are arranged at intervals along the height direction. The first drive shaft 31 passes through the three annular connecting parts 413 in sequence and is fixedly connected. Multiple first support rods 411 are circumferentially connected to the outer peripheral surface of the top annular connecting part 413 at intervals, and the extension direction of the first support rods 411 is the same as the radial direction of the annular connecting part 413. Multiple second support rods 412 are circumferentially connected to the outer peripheral surface of the middle annular connecting part 413 at intervals, and the extension direction of the second support rods 412 intersects the axial direction of the annular connecting part 413. One end of the connecting rod 421 is connected to the first support rod 411, and the other end of the connecting rod 421 is connected to the bottom annular connecting part 413, thereby forming a stable conical structure of the cleaning component 4.

[0049] The length of the first support rod 411 is greater than the length of the second support rod 412. Reinforcing rods are also provided between each of the first support rods 411, between each of the second support rods 412, or between the first support rods 411 and the second support rods 412, to achieve a supporting effect for the first support rods 411 and the second support rods 412. In the support structure 41, the first support rods 411 and the second support rods 412 extend in different directions, forming a spatial truss structure. This structure can transform the complex load formed by bending moment, torque, and axial force into a pure axial force system, improving the overall mechanical strength of the support structure 41. This prevents the cleaning component 4 from malfunctioning and allows the separation device to operate stably for a long time.

[0050] like Figure 3 and Figure 4 As shown in the separation device of this application embodiment, the connecting rods 421 of the plurality of cleaning structures 42 are all of equal length, and the plurality of cleaning structures 42 have at least two sets of cleaning structures 42. The multiple cleaning parts 422 of the different sets of cleaning structures 42 are staggered in their connection positions on the corresponding connecting rods 421, and all the cleaning parts 422 of the plurality of cleaning structures 42 cover the inner surface of the first separation part 11 in the extending direction of the connecting rods 421.

[0051] In practice, the multiple cleaning parts 422 of different groups of cleaning structures 42 are staggered on the corresponding connecting rods 421, which can reduce the number of cleaning parts 422 on each connecting rod 421, avoid excessive weight of each cleaning structure 42, and thus reduce the overall weight of the separation device.

[0052] Furthermore, all the cleaning parts 422 of the multiple cleaning structures 42 cover the inner surface of the first separation part 11 in the extending direction of the connecting rod 421. When the cleaning assembly 4 rotates, all the cleaning parts 422 move together, which can clean the entire inner surface of the first separation part 11 and avoid the residue of dust and tar.

[0053] like Figure 4 As shown, four sets of cleaning structures 42 are illustrated. The connecting rod 421 of the lowest cleaning structure 42 has three cleaning parts 422 arranged at intervals, with the same spacing. The three sets of cleaning structures 42 above it also have three cleaning parts 422 arranged at intervals, but the positions of the cleaning parts 422 in each set of cleaning structures 42 are different. Along the direction from bottom to top, the cleaning parts 422 in each set of cleaning structures 42 are staggered to the right, and the gaps between the cleaning parts 422 in each set can be filled by the cleaning parts 422 in the other three sets. This allows all the cleaning parts 422 to cover the inner surface of the first separation part 11 in the extension direction of the connecting rod 421, thus achieving a comprehensive cleaning effect.

[0054] like Figure 1 and Figure 5 As shown in the embodiment of the present application, the separation device includes a separation cylinder 1 with a plurality of isolation members 12 arranged at intervals along a circular trajectory on its inner surface. The center of the circular trajectory is located on the axis of the support structure 41. The plurality of isolation members 12 are located on the same plane as the maximum diameter of the support structure 41 in the height direction, and each isolation member 12 is spaced apart from the support structure 41.

[0055] In specific implementation, the outer surface of the support structure 41 at its maximum diameter is isolated from the separation cylinder 1 by the isolation member 12. When the cleaning component 4 swings, the outer surface of the support structure 41 at its maximum diameter can contact the isolation member 12 after swinging to a certain angle, thereby stopping further offset and limiting the swing angle A of the first drive shaft 31 connected to the cleaning component 4. This avoids the cleaning component 4 swinging too much, which would result in excessive cutting depth and damage to the separation device.

[0056] The isolation member 12 located on the inner surface of the separation cylinder 1 is on the same plane as the maximum diameter of the support structure 41 in the height direction. When the isolation member 12 is supporting, it will not conflict with the cleaning structure 42 located between the top and bottom of the support structure 41, so as not to affect the cleaning action of the cleaning structure 42 and ensure the cleaning effect of the cleaning component 4.

[0057] like Figure 1 and Figure 2 As shown in the separation device of this application embodiment, the rotation drive mechanism 21 includes a first rotating member 211 with an overall ring structure. The inner peripheral surface of the first rotating member 211 has a mating groove extending in the height direction. The outer peripheral surface of the second drive shaft 32 has a transmission connection portion 323. The inner peripheral surface of the first rotating member 211 is mated and connected with the transmission connection portion 323 of the second drive shaft 32 to drive the second drive shaft 32 to rotate. The extension length of the first rotating member 211 in the height direction is greater than the extension length of the transmission connection portion 323 in the height direction. The lifting drive mechanism 22 is provided at the bottom of the second drive shaft 32 to drive the second drive shaft 32 to move in the height direction.

[0058] In specific implementation, the transmission connection part 323 of the second transmission shaft 32 cooperates with the mating groove on the inner circumferential surface of the first rotating member 211. When the first rotating member 211 rotates, it can drive the transmission connection part 323 to rotate together, so that the transmission shaft assembly 3 as a whole can rotate, and finally the cleaning component 4 connected to the transmission shaft assembly 3 can rotate and clean.

[0059] The lifting drive mechanism 22 located at the bottom of the second drive shaft 32 can drive the second drive shaft 32 to move along the height direction. Since the mating groove extends along the height direction, and the extension length of the first rotating member 211 in the height direction is greater than the extension length of the transmission connection part 323 in the height direction, under the driving action of the lifting drive mechanism 22, the transmission connection part 323 can move along the height direction in the mating groove of the first rotating member 211, so that the second drive shaft 32 as a whole can move along the height direction. Moreover, the movement along the height direction will not affect the connection and fit between the transmission connection part 323 and the mating groove, so that the rotation of the second drive shaft 32 and the movement in the height direction are independent movements, and there will be no mutual interference between the two.

[0060] Specifically, the inner circumferential surface of the first rotating member 211 is an internal spline structure to form multiple mating grooves spaced apart along the circumference, while the outer circumferential surface of the transmission connection part 323 of the second transmission shaft 32 is an external spline structure, which can cooperate with the internal spline structure to achieve a stable mating connection between the first rotating member 211 and the transmission connection part 323, thus ensuring the rotational stability of the transmission shaft assembly 3 and the cleaning assembly 4.

[0061] like Figure 1 and Figure 2 As shown in the separation device of this application embodiment, the rotation drive mechanism 21 further includes a second rotating member 212 and a drive member 213 arranged at intervals from the transmission shaft assembly 3 in the horizontal direction. The drive member 213 has a rotating end 2131 that extends in the height direction and is rotatable. The second rotating member 212 is fixedly connected to the rotating end 2131, and the second rotating member 212 is meshed with the first rotating member 211.

[0062] In practical implementation, the second rotating component 212 and the driving component 213 of the rotary drive mechanism 21 are arranged horizontally at intervals with the transmission shaft assembly 3. Through the meshing connection between the second rotating component 212 and the first rotating component 211, the rotation of the rotating end 2131 of the driving component 213 can be transmitted to the transmission shaft assembly 3, enabling the transmission shaft assembly 3 to rotate under the drive of the side-mounted driving component 213. Therefore, the side-mounted arrangement of the second rotating component 212 and the driving component 213 does not require further increasing the overall height of the separation device, facilitating the installation and maintenance of the entire separation device.

[0063] Specifically, the first rotating component 211 includes a transmission gear 2111 and a hub 2112. The transmission gear 2111 is detachably connected to the outer periphery of the hub 2112, and the outer periphery of the transmission gear 2111 has a tooth structure, which can mesh with the second rotating component 212 through the tooth structure. The inner periphery of the hub 2112 has a mating groove, which can be used for transmission engagement with the transmission connection part 323. The height of the hub 2112 is greater than the height of the transmission gear 2111, so that the transmission connection part 323 can slide along the height direction on the inner surface of the hub 2112. This arrangement eliminates the need for the transmission gear 2111 to be set to an excessively high height, thus reducing the overall weight of the drive assembly 2.

[0064] In the embodiments of this application, the transmission gears 2111 of the second rotating member 212 and the first rotating member 211 can be gears or pin structures, both of which can realize the transmission of rotational action.

[0065] In this embodiment, the drive assembly 2 further includes a mounting bracket 23. The second shaft segment 322 is mounted on the mounting bracket 23 via two radial bearings 231 spaced apart along the height direction, thereby enabling the drive shaft assembly 3 to rotate relative to the mounting bracket 23. The two radial bearings 231 provide two spaced support points for the mounting bracket 23, dispersing the stress acting on the second shaft segment 322 and preventing the second shaft segment 322 from breaking. This also ensures that the second shaft segment 322 is stably mounted on the mounting bracket 23. The transmission connection portion 323 and the first rotating member 211 connected to the transmission connection portion 323 are both located between the two radial bearings 231, thus avoiding conflict with the mounting bracket 23 and ensuring the rotational stability of the drive shaft assembly 3.

[0066] The drive unit 213 also has a corresponding mounting base. The motor, torque detection device, reducer, coupling, and rotating end 2131 of the drive unit 213 are all mounted on the mounting base. The motor speed is controlled by the reducer and connected to the rotating end 2131 through the coupling, thereby controlling the rotation of the rotating end 2131. The torque detection device can be located at the output end of the motor and reducer, or at the connection between different shafts, to detect the torque of the entire device. Based on the torque, the operation status can be judged, realizing real-time detection of the working status of the separation device. This allows for timely adjustment of the lifting and swinging state of the cleaning component 4, preventing malfunctions in the separation device and ensuring its long-term stable operation.
