[0028] A control method for an intelligent unloading system of a powder tank truck: composed of a control system, a controller G, a controller M, a controller N, a controller AA, a controller BB, a controller CC, a controller A, a controller B, a controller C, a remote control interface, a pressure sensor A, a pressure sensor B, a power supply, a plurality of wires, an origin, a plurality of air pipes, and a control system panel;

The signal feedback devices of each butterfly valve are connected to the corresponding controller, so that the control system can know the opening and closing status of each butterfly valve;
[0030] The remote control interface can be connected to a remote controller to operate the control system;
[0031] Pressure sensor A and pressure sensor B provide pressure data for the system respectively.
[0032] Working principle: When the present invention is used, when unloading is required, the vehicle is parked, the unloading pipe port 23 is connected to the storage, the air inlet pipe port 39 is connected to an external compressed air source, and other preparations are completed, and the unloading operation is ready to start.
[0033] Turn on the main switch, the control system opens the pneumatic butterfly valve G40 through the controller G, and the compressed gas passes through the one-way valve 41. This one-way valve 41 prevents the gas from flowing in the opposite direction and damaging the external source system when the pressure of the external gas source is lower than the pressure inside the gas pipe and the tank body 1. The compressed gas continues to flow in the direction of the arrow shown in the attached figure (2). The gas circuit assembly is provided with a safety valve 42. This safety valve 42 sets the discharge pressure value. When the pressure in the system exceeds the discharge pressure value, the safety valve 42 opens to release the pressure and protect the entire system.
[0034] When the left end hopper is unloading, the A switch is turned on, and the control system opens the pneumatic butterfly valve A38 and the pneumatic valve A4 through the controller A, and the compressed gas enters the funnel A through the blowing port A3, so that the powder and granular materials inside the tank body 1 are fluidized, and the powder and granular materials are discharged from the funnel A, and enter the storage through the pneumatic valve A4, the secondary blowing device A5, the unloading main pipe 13, and the unloading pipe port 23. When no material enters the storage, the A switch is turned off. In this unloading process, when the pressure of the pressure sensor B22 is too low, the control system opens the pneumatic butterfly valve N32 and the pneumatic butterfly valve AA26 through the controller N and the controller AA, and the compressed gas enters the secondary blowing device A5 through the secondary blowing port A6, giving the powder and granular materials in the unloading pipe A7 more gas power, speeding up the unloading speed and flow rate. When the unloading speed is increased, when the pressure of the pressure sensor B22 rises to the set value, the control system closes the pneumatic butterfly valve N32 and the pneumatic butterfly valve AA26 through the controller N and the controller AA. If it is a manual operation, the operator needs to pay attention to the flow of powder and particles in the discharge pipe at all times, such as observing the vibration of the pipe or going directly to the observation port of the storage to observe the flow speed and flow rate of the powder and particles. When the flow speed and flow rate decrease, the corresponding secondary blowing device is turned on to give the powder and particles in the discharge pipe more gas power to speed up the discharge speed and flow rate.
[0035] When hopper B is unloading, switch B is turned on, and the control system opens pneumatic butterfly valve B34 and pneumatic valve B9 through controller B, and compressed gas enters hopper B through blowing port B8, so that the powder and granular materials inside tank body 1 are fluidized, and the powder and granular materials are discharged from hopper B, and enter the storage through pneumatic valve B9, secondary blowing device B10, unloading main pipe 13, and unloading pipe port 23. When no material enters the storage, switch B is turned off. During this unloading process, when the pressure of pressure sensor B22 is too low, the control system opens pneumatic butterfly valve N32 and pneumatic butterfly valve BB30 through controller N and controller BB, and compressed gas enters secondary blowing device B10 through secondary blowing port B11, giving more gas power to the powder and granular materials in unloading pipe B12, speeding up the unloading speed and flow rate. When the unloading speed is increased, when the pressure of pressure sensor B22 rises to the set value, the control system closes pneumatic butterfly valve N32 and pneumatic butterfly valve BB30 through controller N and controller BB. If it is a manual operation, the operator needs to pay attention to the flow of powder and particles in the discharge pipe at all times, such as observing the vibration of the pipe or going directly to the observation port of the storage to observe the flow speed and flow rate of the powder and particles. When the flow speed and flow rate decrease, the corresponding secondary blowing device is turned on to give the powder and particles in the discharge pipe more gas power to speed up the discharge speed and flow rate.
[0036] When the hopper C is unloading, the C switch is turned on, and the control system opens the pneumatic butterfly valve C36 and the pneumatic valve C18 through the controller C, and the compressed gas enters the hopper C through the blowing port C17, so that the powder and granular materials inside the tank body 1 are fluidized, and the powder and granular materials are discharged from the hopper C, and enter the storage through the pneumatic valve C18, the secondary blowing device C19, the unloading main pipe 13, and the unloading pipe port 23. When no material enters the storage, the C switch is turned off. During this unloading process, when the pressure of the pressure sensor B22 is too low, the control system opens the pneumatic butterfly valve N32 and the pneumatic butterfly valve CC28 through the controller N and the controller CC, and the compressed gas enters the secondary blowing device C19 through the secondary blowing port C20, giving the powder and granular materials in the unloading pipe more gas power, speeding up the unloading speed and flow rate. When the unloading speed is increased, when the pressure of the pressure sensor B22 rises to the set value, the control system closes the pneumatic butterfly valve N32 and the pneumatic butterfly valve CC28 through the controller N and the controller CC. If it is a manual operation, the operator needs to pay attention to the flow of powder and particles in the discharge pipe at all times, such as observing the vibration of the pipe or going directly to the observation port of the storage to observe the flow speed and flow rate of the powder and particles. When the flow speed and flow rate decrease, the corresponding secondary blowing device is turned on to give the powder and particles in the discharge pipe more gas power to speed up the discharge speed and flow rate.
[0037] When hopper A, hopper B, and hopper C are unloading at the same time, switch A, switch B, and switch C are turned on at the same time, and the control system turns on pneumatic butterfly valve A38, pneumatic butterfly valve B34, pneumatic butterfly valve C36, and pneumatic valve A4, pneumatic valve B9, and pneumatic valve C18 through controller A, controller B, and controller C at the same time, and compressed gas enters hopper A, hopper B, and hopper C through auxiliary blowing port A3, auxiliary blowing port B8, and auxiliary blowing port C17, so that the powder and granular materials inside the tank body 1 are fluidized, and the powder and granular materials are discharged from hopper A, hopper B, and hopper C, and enter the storage through pneumatic valve A4, pneumatic valve B9, pneumatic valve C18, secondary auxiliary blowing device A5, secondary auxiliary blowing device B10, secondary auxiliary blowing device C19, unloading main pipe 13, and unloading pipe port 23. When no materials enter the storage, switch A, switch B, and switch C are turned off. During the unloading process, when the pressure of pressure sensor B22 is too low, the control system opens pneumatic butterfly valve N32, pneumatic butterfly valve AA26, pneumatic butterfly valve BB30, and pneumatic butterfly valve CC28 through controller N, controller AA, controller BB, and controller CC at the same time, and the compressed gas enters secondary blowing device A5, secondary blowing device B10, and secondary blowing device C19 through secondary blowing port A6, secondary blowing port B11, and secondary blowing port C20, respectively, giving more gas power to the powder and granular materials in the unloading pipe, speeding up the unloading speed and flow rate. When the unloading speed is increased and the pressure of pressure sensor B22 rises to the set value, the control system closes pneumatic butterfly valve N32, pneumatic butterfly valve AA26, pneumatic butterfly valve BB30, and pneumatic butterfly valve CC28 through controller N, controller AA, controller BB, and controller CC. If it is a manual operation, the operator needs to pay attention to the flow of powder and particles in the discharge pipe at all times, such as observing the vibration of the pipe or going directly to the observation port of the storage to observe the flow speed and flow rate of the powder and particles. When the flow speed and flow rate decrease, the corresponding secondary blowing device is turned on to give the powder and particles in the discharge pipe more gas power to speed up the discharge speed and flow rate.
[0038] In addition, funnel A and funnel B can unload materials at the same time, or funnel A and funnel C can unload materials at the same time, or funnel C and funnel B can unload materials at the same time.
[0039] When the entire unloading is completed, turn off the main switch, disconnect the external air source, disconnect the unloading pipe and the storage, and the entire vehicle is reset to a drivable state.
[0040] During the entire unloading process, when the pressure of the pressure sensor A2 is higher than the set value, the control system opens the pneumatic butterfly valve M15 through the controller M, and the compressed gas in the tank body 1 and the gas circuit can be discharged to the atmosphere through the pressure relief pipe 14 to protect the entire system. The pressure setting value of the pressure sensor A2 should be slightly higher than the discharge pressure value of the safety valve. Under normal conditions, when the system pressure value is too high, the safety valve 42 will first play a protective role. When the safety valve 42 fails, the control system controls the pressure relief to play a protective role. That is, the entire system has double protection. If it is manually operated, it is necessary to install a pressure display gauge and always pay attention to the pressure gauge reading. When the pressure exceeds the safety value, if the safety valve 42 does not work, the operator should quickly open the pressure relief valve to relieve pressure and reduce the pressure in the tank. If it still does not work, immediately close the external source to avoid accidents.
[0041] When remote control is required, use the remote control to connect to the remote control interface. The distance can be set according to the actual situation to facilitate the control of unloading. Remote control is the best for the safety protection of operators. Even if there is an unexpected high-pressure gas injection or high-pressure powder injection, there is enough safety distance to prevent harm to the operator.
[0042] To sum up, after the unloading pipe port of a powder tank truck is connected to the storage, and the air inlet is connected to the external source, the operator can complete all unloading operations in front of the operation panel or at a suitable position by remote control. Compared with manual unloading, there is no need to reach the position of each control valve to operate its switch, nor is there any need to pay attention to the unloading speed and flow rate at all times to determine whether it is necessary to turn on the secondary blowing device, nor is there any need to pay attention to the pressure in the tank at all times to determine whether it is necessary to immediately close the external air source or release the pressure.
[0043] Beneficial effects: The invention has novel structure, ingenious conception, more intelligent operation, higher efficiency and better safety, can effectively ensure safe and rapid unloading, and effectively reduce the probability of human error.
