Description

Technical Field

[0001] The invention belongs to the technical field of regulating valves, and in particular relates to a fisheye regulating valve for a dust removal device and a control method thereof. Background Art

[0002] In the existing dust removal system, the adjustment of air volume and dust collection efficiency usually depends on the traditional cover-type butterfly valve. For example, the reference patent number is CN202323510522.X, which is an intelligent regulating electric butterfly valve, in which the butterfly valve mainly includes a valve body with a hollow flow channel and a butterfly plate (circular or elliptical) rotatably installed inside the valve body. When the butterfly plate rotates to a position parallel to the flow direction of the fluid, the valve is in an open state, and the fluid can pass freely; when the butterfly plate rotates to a position perpendicular to the flow direction of the fluid, the valve is in a closed state, and the fluid is blocked from flowing; and then the staff can control the butterfly plate to rotate to different angles to control the flow of the fluid, but in actual applications, the following problems still exist:

[0003] 1. The fluid may carry fibrous materials such as cloth strips, which may be stuck between the butterfly plate and the valve seat when passing through the valve, resulting in the phenomenon of hanging cloth strips, thus affecting the normal operation of the valve;

[0004] 2. The rotation of the butterfly plate may not be completely aligned with the direction of fluid flow, resulting in uneven distribution of airflow when passing through the valve, which in turn causes uneven distribution of the fluid's flushing effect on the butterfly plate and pressure impact force, easily leading to uneven wear of the butterfly plate and the valve seat; 3. Due to different numbers of branches and different pipe diameters, the internal pressure of the system will be unbalanced, affecting the dust removal efficiency and system stability.

[0005] Based on this background, a fisheye regulating valve for a dust removal device is designed. The regulating valve as a whole is in the shape of a sphere with a hollow interior.

[0050] Example 2

[0051] like Figures 1 to 9A fisheye regulating valve for a dust removal device shown in the figure includes a symmetrically arranged first flange 2 and a second flange 3. According to actual use, the regulating valve of this embodiment is mostly installed in a vertical pipe, and the first flange 2 and the second flange 3 are symmetrical in the vertical direction. When the regulating valve is installed in a horizontal pipe, it is symmetrical in the left and right direction. For the convenience of understanding, this embodiment temporarily sets the first flange 2 and the second flange 3 to be symmetrical in the left and right direction, and a shell 1 is connected between the first flange 2 and the second flange 3, and the shell 1 and its internal structure together constitute the regulating valve; and then the first flange 2 and the second flange 3 are provided with a plurality of mounting holes 4 for adapting to the installation of pipes or other connection platforms. In actual installation, nuts or nut + gasket components can be selected to ensure the sealing of the flow channel.

[0052] It should be noted that the specific structure of the existing common cover-type butterfly valve can refer to the intelligent regulating electric butterfly valve with patent number CN202323510522.X, in which the butterfly valve mainly includes a valve body with a hollow flow channel and a butterfly plate (circular or elliptical) rotatably installed inside the valve body. When the butterfly plate rotates to a position parallel to the direction of fluid flow, the valve is in an open state and the fluid can pass freely; when the butterfly plate rotates to a position perpendicular to the direction of fluid flow, the valve is in a closed state and the fluid is blocked from flowing; and then the staff can control the flow of the fluid by rotating the butterfly plate to different angles.

[0053] However, in actual applications, the fluid may carry fibrous materials such as cloth strips, which may be stuck between the butterfly plate and the valve seat when passing through the valve, resulting in the phenomenon of hanging cloth strips, thus affecting the normal operation of the valve; and the rotation of the butterfly plate may not be completely aligned with the flow direction of the fluid, which can easily lead to uneven distribution of the airflow when passing through the valve, and then the scouring effect of the fluid on the disc plate and the pressure impact force will be unevenly distributed, which can easily lead to uneven wear of the butterfly plate and the valve seat, thereby reducing the sealing performance of the valve and affecting the ultimate service life and adjustment accuracy of the valve.

[0054] Based on the above background, in this embodiment, the shell 1 is presented as a spherical shape with a hollow interior. The left and right sides thereof are provided with a first flange 2 and a second flange 3 by opening a first vent 201 and a second vent 301. The flanges and the vents are in a connected state, that is, the regulating valve as a whole is in the shape of a sphere with left and right connected cylinders; a first adjusting plate 52 and a second adjusting plate 62 are rotatably provided in the shell 1, and both are arc-shaped to adapt to the shape of the shell 1. The first adjusting plate 52 and the second adjusting plate 62 are both in contact with the inner wall of the shell 1, and then the first adjusting plate 52 and the second adjusting plate 62 are adjusted to rotate to achieve flow control of the fluid, wherein the combined area of ​​the first adjusting plate 52 and the second adjusting plate 62 will be larger than the area of ​​the first vent 201, and then when the first adjusting plate 52 and the second adjusting plate 62 rotate to contact each other, it means that the combination of the first adjusting plate 52 and the second adjusting plate 62 blocks the first vent 201, driving the entire regulating valve to be in a closed state. In this way, based on the rounded appearance design of the first adjustment plate 52 and the second adjustment plate 62, the debris carried by the airflow will not be easily caught when passing through; and in actual applications, the regulating valve is in a vertical state. When it is in a closed state, the combination of the first adjustment plate 52 and the second adjustment plate 62 will block the first vent 201 of the first flange 2, and the debris will automatically fall down, thereby avoiding the problem of fibrous debris blocking the regulating valve and affecting the normal use of the subsequent regulating valve.

[0055] A first rotating shaft 51 is rotatably provided on the front side of the shell 1, and a second rotating shaft 61 is rotatably provided on the rear side of the shell 1. The first rotating shaft 51 and the second rotating shaft 61 are on the same horizontal line, and the first adjusting plate 52 and the second adjusting plate 62 are connected between the first rotating shaft 51 and the second rotating shaft 61; it can be understood that the first adjusting plate 52 located at the top has two front and rear arc plates, and the second adjusting plate 62 located at the bottom has two front and rear angle plates, and the arc plates are both located on the outside of the angle plates, so that the first adjusting plate 52 and the second adjusting plate 62 can rotate without affecting each other.

[0056] Further, the arc plate is divided into a first arc plate 531 and a second arc plate 532, the first arc plate 531 located at the front side is fixedly connected to the first rotating shaft 51, and the second arc plate 532 is rotatably connected to the second rotating shaft 61; the angle plate is divided into a first angle plate 631 and a second angle plate 632, the first angle plate 631 located at the front side is rotatably connected to the first rotating shaft 51, and the second angle plate 632 is fixedly connected to the second rotating shaft 61. In simple terms, the rotation of the first rotating shaft 51 can drive the first adjustment plate 52 to rotate in the housing 1 through the first arc plate 531, at which time the second arc plate 532 rotates on the second rotating shaft 61, and the second rotating shaft 61 plays a supporting role; and the rotation of the second rotating shaft 61 can drive the second adjustment plate 62 to rotate in the housing 1 through the second angle plate 632, at which time the first angle plate 631 rotates on the first rotating shaft 51, and the first rotating shaft 51 plays a supporting role.

[0057] In summary, based on the connection center line between the first rotating shaft 51 and the second rotating shaft 61, the first adjusting plate 52 and the second adjusting plate 62 are in a vertically symmetrical state in the housing 1, such as Figure 1-5 As shown, this is the maximum flow state of the regulating valve, and Figure 7-9 As shown, the first adjustment plate 52 and the second adjustment plate 62 are both rotated toward the first vent 201 until the two are in contact with each other to complete the combination, thereby blocking the first vent 201, and the regulating valve is in a closed state; then, the staff can adjust the rotation amplitude of the first adjustment plate 52 and the second adjustment plate 62 in the shell 1 to control the size of the fluid channel formed by the two, and finally realize the flow control of the fluid.

[0058] Furthermore, a first adjusting member 54 is provided on the first rotating shaft 51 at the front side of the housing 1, and a second adjusting member 64 is provided on the second rotating shaft 61 at the rear side of the housing 1, so as to allow the staff to realize the rotation adjustment of the first adjusting plate 52 and the second adjusting plate 62 on the outside of the regulating valve. Specifically:

[0059] A first fan-shaped adjustment plate 541 is provided on the first rotating shaft 51, and a first handle 542 is provided on the top of the first fan-shaped adjustment plate 541. Pushing the first handle 542 can drive the first fan-shaped adjustment plate 541 and the first rotating shaft 51 to rotate, thereby realizing the adjustment rotation of the first adjustment plate 52; a second fan-shaped adjustment plate 641 is provided on the second rotating shaft 61, and a second handle 642 is provided at the bottom of the second fan-shaped adjustment plate 641. Pushing the second handle 642 can drive the second fan-shaped adjustment plate 641 and the second rotating shaft 61 to rotate, thereby realizing the adjustment rotation of the second adjustment plate 62.

[0060] Example 3

[0061] like Figures 1 to 9 The fisheye regulating valve for a dust removal device shown in the figure realizes the adjustment rotation of the first adjusting plate 52 by pushing the first handle 542 to drive the first fan-shaped adjusting plate 541 and the first rotating shaft 51 to rotate; and realizes the adjustment rotation of the second adjusting plate 62 by pushing the second handle 642 to drive the second fan-shaped adjusting plate 641 and the second rotating shaft 61 to rotate; in this way, the rotation amplitude of the first adjusting plate 52 and the second adjusting plate 62 in the shell 1 can be adjusted to control the size of the fluid channel formed by the two, and finally realize the flow control of the fluid.

[0062] At the same time, in order to achieve accurate and stable adjustment of the first adjustment plate 52 and the second adjustment plate 62, a guiding structure is also provided. A first arc groove 543 is opened at the centrifugal edge of the first fan-shaped adjustment plate 541, and a first guide rod 7 is provided on the front side of the shell 1. The first guide rod 7 is located in the first arc groove 543. When the regulating valve is at the maximum ventilation volume, the first guide rod 7 is at the lowest point of the first arc groove 543; a second arc groove 643 is opened at the centrifugal edge of the second fan-shaped adjustment plate 641, and a second guide rod 8 is provided on the rear side of the shell 1. The second guide rod 8 is located in the second arc groove 643. When the regulating valve is at the maximum ventilation volume, the second guide rod 8 is at the highest point of the second arc groove 643.

[0063] Among them, the first guide rod 7 and the second guide rod 8 are symmetrically arranged, so that when the first handle 542 is pushed to drive the first fan-shaped adjustment plate 541 to rotate, the first fan-shaped adjustment plate 541 can be driven to rotate stably under the guidance of the first arc groove 543, so as to accurately adjust the angle of the first adjustment plate 52, and a first limit block 701 is threadedly provided on the first guide rod 7 at a position in front of the first arc groove 543. It can be understood that after completing the adjustment of the first fan-shaped adjustment plate 541, the staff can fix the adjusted first fan-shaped adjustment plate 541 to the shell 1 by rotating the first limit block 701. Similarly, a second limit block 801 is threadedly provided on the second guide rod 8 at the rear side of the second arc groove 643. After the staff completes the adjustment of the second fan-shaped adjustment plate 641, the second limit block 801 is rotated to fix the adjusted second fan-shaped adjustment plate 641 to the shell 1; and when it is necessary to adjust again, the first limit block 701 and the second limit block 801 are rotated to no longer tighten the first fan-shaped adjustment plate 541 and the second fan-shaped adjustment plate 641, and the handle is pushed to drive the corresponding fan-shaped adjustment plate to rotate and adjust.

[0064] Furthermore, angle values ​​can be engraved on the first fan-shaped adjustment plate 541 and the second fan-shaped adjustment plate 641 at the position outside the arc groove for manual adjustment monitoring and reference of the internal first adjustment plate 52 and the second adjustment plate 62; with the guide rod as the starting point and the arc groove as the trajectory angle, specific and clear numbers are used to guide the staff to adjust to the required fluid channel, thereby improving the accuracy of the adjustment.

[0065] Example 4

[0066] In another feasible embodiment, electrical devices can be used to replace the manual adjustment drive of the first fan-shaped adjustment plate 541 and the second fan-shaped adjustment plate 641. Such electrical devices include but are not limited to any one of motors, telescopic rods, etc. that can drive the fan-shaped adjustment plates to rotate; for ease of understanding, this embodiment specifically uses the motor as a driving member, which is divided into a first motor and a second motor. The first motor is connected to the first rotating shaft 51, and the second motor is connected to the second rotating shaft 61. The first rotating shaft 51 and the second rotating shaft 61 are driven by driving the first motor and the second motor to achieve the driving of the first rotating shaft 51 and the second rotating shaft 61, and the subsequent adjustment of the first adjustment plate 52 and the second adjustment plate 62 is achieved. The first adjustment plate 52 and the second adjustment plate 62 present the required rotation amplitude in the shell 1, thereby controlling the size of the fluid channel formed by the two, and finally achieving the flow control of the fluid.

[0067] Example 5

[0068] Based on the above implementation scheme, this embodiment also proposes a control method based on electric adjustment, which is used to drive the first adjustment plate 52 and the second adjustment plate 62 to rotate synchronously at the same angle, so that the fluid channel finally formed is always in a balanced state with the fluid flow direction, driving the fluid to pass through in a concentrated manner, making it easier to take away dust and improving the dust removal efficiency; and the concentrated passage of the fluid can also ensure its uniform impact force, thereby uniformly affecting the loss of the first adjustment plate 52 and the second adjustment plate 62, thereby ensuring the sealing performance of the valve and the ultimate service life and adjustment accuracy of the valve.

[0069] The above control method may include the cooperation of various sensors and PID controllers, specifically:

[0070] The sensor may be an optical sensor or a gyroscope or other sensors that can be used to measure the angle change of an object. The angle information of the first rotating shaft 51 and the second rotating shaft 61 is obtained by multiple sensors at the same time to ensure the same angle and synchronous adjustment and rotation of the first adjusting plate 52 and the second adjusting plate 62.

[0071] The PID controller includes three parts: proportional (P), integral (I) and differential (D), which can be used to achieve precise control of the rotation angle of the motor on the shaft. The output signals of multiple angle sensors are used as input data of the PID controller, and then the PID controller calculates and outputs corresponding control signals, such as the data signal of the shaft reaching the target angle from the original angle, to finally achieve precise angle control of the shaft. After coordinated control by the PID controller, the angle synchronization control of the first shaft 51 and the second shaft 61 can be achieved.

[0072] The specific steps are:

[0073] S01 drives the first motor and the second motor of the first rotating shaft 51 and the second rotating shaft 61 simultaneously to ensure that the angles of the two change synchronously;

[0074] S02 simultaneously obtains angle information of the first rotating shaft 51 and the second rotating shaft 61 through an angle sensor;

[0075] S03 collects angle information data and transmits it to the central processing unit of the PID controller;

[0076] S04 uses the output signal of the angle sensor as input data of the PID controller; S05 reads the angle data of the first rotating shaft 51 and the second rotating shaft 61 in real time, calculates the angle error between the two, and calculates the control signals of the first rotating shaft 51 and the second rotating shaft 61 respectively according to the angle error;

[0077] S06 outputs corresponding control signals through calculation by the PID controller to achieve precise angle control of the first rotating shaft 51 and the second rotating shaft 61 .

[0078] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
