Description

Technical Field

[0001] The utility model relates to the technical field of valve equipment, in particular to an atomizing valve for multi-flow mixed delivery. Background Art

[0002] A valve is a device used to control the direction, pressure, and flow of fluid in a fluid system. It is a device that allows the medium in pipes and equipment to flow or stop and control its flow. It has functions such as diversion, cut-off, throttling, check, diversion, or overflow pressure relief. The valve relies on a drive or automatic mechanism to make the opening and closing parts move up and down, slide, swing, or rotate, thereby changing the size of the flow area inside the valve to achieve its control function. There are many types and specifications of valves used for fluid control. According to the control method, they can be divided into manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic hydraulic, electro-hydraulic, gas-hydraulic, etc.

[0003] The valves currently used are all kept stationary at a given valve position opening, thereby changing the amount or speed of material flow in the pipeline. This type of valve is very useful for previous adjustments, but with the diversity of the fluids being transported, a pipeline may no longer simply transport a single material. For example, a gas may be used to carry a mixed flow of solids, or one liquid may be mixed with another liquid to flow, or a mixture of gas and liquid may be transported. In this case, if the valve opening is simply controlled, the total amount of material transported is simply controlled, but the uniformity and mixing degree of the transport are not taken into account during the transport process. Therefore, in order to solve the above problems, the utility model proposes an atomizing valve for multi-flow mixed transport. Utility Model Content

[0004] In response to the deficiencies in the prior art, the utility model provides an atomizing valve for multi-stream mixed conveying. While adjusting the conveying volume during the material conveying process, the valve always maintains a reciprocating swinging motion, maintaining a large-to-small change process at a certain frequency and amplitude in the front cavity of the material conveying, and a small-to-large change process in the rear cavity immediately behind the valve, thereby achieving a certain degree of atomization effect on the mixing of the materials, making the materials more evenly mixed during the conveying process.

[0005] The utility model provides the following technical solutions: an atomizing valve for multi-stream mixed delivery, comprising a valve body, a motor fixedly mounted on the front of the valve body, the motor output shaft movably sleeved in the inner cavity of the valve body, a valve plate fixedly sleeved on the motor output shaft and located in the inner cavity of the valve body, a runner fixedly sleeved at the rear end of the motor output shaft and located directly behind the valve body, a driver fixedly mounted on the right side of the motor, a feedback device fixedly mounted in front of the driver, an actuator provided on the left side of the valve body, a control panel fixedly mounted on the upper part of the actuator, a circuit fixedly mounted in front of the actuator, two circuits symmetrically distributed on the left and right, and the other end of the circuit fixedly mounted on the bottom of the feedback device.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] 1. When the material is conveyed inside the valve, the valve plate in the valve cavity can always keep reciprocating while adjusting the conveying volume. This adjustment method allows the front cavity of the valve to convey the material to maintain a certain frequency and amplitude change, large and small, and the rear cavity of the valve also keeps the opposite change to the front cavity, thereby playing a certain degree of atomization process for the mixing of the material, making the material mixed more evenly during the conveying process, and solving the problem of more material at the bottom and less material at the top due to gravity during conveying, which is not conducive to uniform mixing.

[0008] 2. The impact force generated by the material rushing onto the valve plate is constantly changing. The actuator can adjust the torque size in time according to the size of the impact force on the valve plate. After the valve plate reaches the specified position, it will swing back and forth continuously with the specified swing amplitude. By swinging back and forth, the flushing angle of the material on the valve plate is changed, so that the material will not cause blockage and prevent the adhesion of powder. The equipment does not stop during operation to prevent affecting production. The full opening and closing positioning of the actuator is completed directly through calculation to achieve the purpose of normal production. BRIEF DESCRIPTION OF THE DRAWINGS

The control algorithm unit ① first receives the control signal transmitted to the control signal input unit ⑥ through the connection module ⑨. At the same time, the control algorithm unit ① receives the changeable swing signal transmitted from the display unit ⑤. The control algorithm ① changes the degree of atomization according to the swing amplitude and swing rate set by the display unit ⑤. Then the control unit ① transmits the combined position signal of the received control signal and the swing signal superimposed together to the drive unit ②. After receiving the specific position signal, the drive unit ② adjusts the voltage and current signals respectively through the position control mode to drive the motor execution unit ③ to rotate to the required position. When the motor execution unit ③ rotates to the position, the drive unit ② Instead of cutting off the power supply, a set of three-phase driving power is continuously supplied to the motor execution unit ③, so that the motor 2 can maintain a dynamic balance at this time (if the swing amplitude is set to 0), so as to avoid the original actuator 7 from being powered off, and provide time for the motor execution unit ③ to dissipate heat, so as to prevent affecting the control speed. If a new control signal comes at this time, the driving unit ② reduces the time to supply power to the motor execution unit ③ again, and the motor execution unit ③ moves to the new specified position in time. If the swing amplitude is not set to 0 at this time, when the motor reaches the position specified by the control signal, it will use the current position as the midpoint and the swing amplitude as the swing amplitude to swing the specified amplitude before and after. If the position is at 0% or 100% at this time, in order to prevent exceeding the minimum range or maximum range, Range, at this time the swing only swings half, if the control signal is 0% at this time, it only swings within the range of 0% plus the swing amplitude, if the control signal is 100% at this time, the swing swings within the range of 100% minus the swing amplitude, if the control signal is 50% at this time, the swing swings within the range of 50 plus the swing amplitude and 50 minus the swing amplitude, ultimately ensuring that the actuator 7 will neither exceed the maximum range nor the minimum range, while also satisfying the back and forth swing within the range, in order to ensure that the motor execution unit ③ reaches the specified control signal and swing amplitude combination position in a timely and accurate manner, the encoder feedback signal of the motor execution unit ③ is transmitted to the drive unit ② in a timely manner. Once the drive unit ② cannot compare the position, it directly controls the motor execution unit ③ to reach the position in time,Instead of first transmitting it to the control algorithm unit ① and then transmitting it to the drive unit ②, and then transmitting it to the motor execution unit ③, this ensures both real-time performance and accuracy. At the same time, the drive unit ② will also promptly transmit the signal of the current arrival position to the control algorithm unit ①. The control algorithm unit ① will re-compare the received control signal and the swing amplitude signal of the display unit ⑤ to see if there is any change, and whether a new position signal needs to be recombined. Finally, the control algorithm unit ① transmits the current position signal to the connection module ⑨ through the feedback signal output unit ⑦. The connection module ⑨ finally transmits the current position signal to other equipment. When the material is conveyed inside the valve body 1, the valve plate 3 in the inner cavity of the valve body 1 can always keep swinging back and forth while adjusting the conveying volume. This adjustment method enables the front cavity of the valve body 1 to maintain a certain frequency and amplitude change for the material conveying, and the rear cavity of the valve body 1 also synchronously maintains the opposite change to the front cavity, thereby playing a certain degree of atomization process for the mixing of the material, making the material more evenly mixed during the conveying process, and solving the problem of more material at the bottom and less material at the top due to gravity during conveying, which is not conducive to uniform mixing;

[0015] The normal existing actuator must move the actuator through the full stroke from the minimum to the maximum range when setting the minimum and maximum values ​​of the range, otherwise it cannot be used. When the user does not reserve time for debugging during the installation of the actuator 7, and the equipment has started to operate, the current position of the motor actuator unit ③ can be set to the minimum value or the maximum value of the range through the display unit ⑤, and then the corresponding maximum value or minimum value can be directly calculated according to the reduction ratio of the matching reducer, and then the minimum and maximum values ​​of the range are directly set through the display unit ⑤, that is, the range setting is completed, which avoids delaying the use of the device and avoiding the inability to debug the device. In order to achieve different speeds for a valve plate 3 at different positions, the entire stroke of 0-100% can be divided into up to five different position segments corresponding to five different speeds on the display unit ⑤, such as The 0-20% position speed is set to 2 rev / s, the 21-40% position speed is set to 4 rev / s, the 41-60% position speed is set to 3 rev / s, the 61-80% position speed is set to 3 rev / s, and the 81-100% position speed is set to 5 rev / s. The display unit ⑤ then transmits these parameters to the control algorithm unit ①. The control algorithm unit ① will first compare which parameter the current position is within, and then the control algorithm unit ① will use which speed to control the drive unit ② and the motor execution unit ③. The actuator 7 can adjust the torque in time according to the impact force on the valve plate 3. After the valve plate 3 reaches the specified position, it swings back and forth continuously with the specified swing amplitude. The back-and-forth swing changes the flushing angle of the material on the valve plate 3, so that the material will not cause blockage and prevent the adhesion of the powder. When the equipment is running, the full-open and full-close positioning of the actuator is completed directly through calculation to avoid downtime affecting the normal production of the enterprise.

[0016] Working principle: The power supply transmits the power supply to the power module ⑧ through the connection module ⑨, and the power module ⑧ is connected to the control algorithm unit ① through the circuit to provide working power for the control algorithm unit ①. The control algorithm unit ① first receives the control signal transmitted to the control signal input unit ⑥ through the connection module ⑨. At the same time, the control algorithm unit ① receives the changeable swing signal transmitted from the display unit ⑤. The control algorithm ① changes the degree of atomization according to the swing amplitude and swing rate set by the display unit ⑤. Then the control unit ① transmits the combined position signal of the received control signal and the swing signal to the drive unit ②. After receiving the specific position signal, the drive unit ② adjusts the voltage and current signals respectively through the position control mode to drive the motor. The motor execution unit ③ rotates to the required position. When the motor execution unit ③ rotates to the position, the drive unit ② does not cut off the power but keeps supplying a set of three-phase drive power to the motor execution unit ③, so that the motor 2 can maintain a dynamic balance at this time (if the swing amplitude is set to 0), so as to avoid the original actuator 7 from being powered off, and provide time for the motor execution unit ③ to dissipate heat, so as to prevent the control speed from being affected. If a new control signal comes at this time, the drive unit ② reduces the time to supply power to the motor execution unit ③ again, and the motor execution unit ③ moves to the new specified position in time. If the swing amplitude is not set to 0 at this time, when the motor reaches the position specified by the control signal, it will swing back and forth with the current position as the midpoint and the swing amplitude as the swing amplitude. If the position is 0% or 100% at this time, in order to prevent exceeding the minimum range or maximum range, the swing only swings halfway. If the control signal is 0% at this time, it only swings within the range of 0% plus the swing amplitude. If the control signal is 100% at this time, the swing swings within the range of 100% minus the swing amplitude. If the control signal is 50% at this time, the swing swings within the range of 50 plus the swing amplitude and 50 minus the swing amplitude. Ultimately, it is ensured that the actuator 7 will neither exceed the maximum range nor the minimum range, and at the same time, it also meets the swing back and forth within the range. In order to ensure that the motor execution unit ③ reaches the specified combination position of the control signal and the swing amplitude in a timely and accurate manner, the encoder feedback signal of the motor execution unit ③ is transmitted to Driving unit ②, once driving unit ② cannot find the position by comparison, it directly controls motor execution unit ③ to reach the position in time, instead of first transmitting it to control algorithm unit ① and then transmitting it to driving unit ②, and then transmitting it to motor execution unit ③ again. This ensures both real-time performance and accuracy. At the same time, driving unit ② will also transmit the signal of the current arrival position to control algorithm unit ① in time. Control algorithm unit ① will re-compare the received control signal and the swing signal of display unit ⑤ to see if there is any change, and whether a new position signal needs to be recombined. Finally, control algorithm unit ① transmits the current position signal to connection module ⑨ through feedback signal output unit ⑦, and connection module ⑨ finally transmits the current position signal to other devices.The normal existing actuator must move the actuator through the full stroke from the minimum to the maximum range when setting the minimum and maximum values ​​of the range, otherwise it cannot be used. When the user does not reserve time for debugging during the installation of the actuator 7, and the equipment has started to be put into operation, the current position of the motor actuator unit ③ can be set to the minimum value or the maximum value of the range through the display unit ⑤, and then the corresponding maximum value or minimum value can be directly calculated according to the reduction ratio of the matching reducer, and then the minimum and maximum values ​​of the range are directly set through the display unit ⑤, that is, the range setting is completed, which avoids delaying the use of the device and avoiding the inability to debug the device. In order to achieve different speeds for a valve plate 3 at different positions, the entire stroke of 0-100% can be divided into up to five different position segments corresponding to five different speeds on the display unit ⑤. For example, the speed of the 0-20% position can be set to 2 rev / s, the speed of the 21-40% position can be set to 4 rev / s, the speed of the 41-60% position can be set to 3 rev / s, the speed of the 61-80% position can be set to 3 rev / s, and the speed of the 81-100% position can be set to 5 rev / s. The display unit ⑤ then transmits these parameters to the control algorithm unit ①. The control algorithm unit ① will first compare which segment the current position falls within, and then the control algorithm unit ① will use the speed of that segment to control the drive unit ② and the motor execution unit ③.
