Of course, keys may be disposed around the display screen 160 to realize the interaction between the user and the display screen 160, and are not limited in this respect.
The principle of discharging the powder from the tank 100 will be explained.
After the gas enters the tank 100 from the gas inlet 110, if the gas flow rate exceeds a certain value, the friction force between the gas and the powder in the tank 100 is equal to the weight of the powder, and the powder no longer depends on the inner wall of the tank 100 for support, so that the powder can move freely and flow from a high position to a low position, similar to the property of liquid. At this time, if the discharge port 120 of the can 100 is opened, the powder can be discharged from the discharge port 120, and this phenomenon is called fluidization of the powder. The discharge system of the present disclosure is for discharging the powder in the tank 100 by means of fluidization of the powder.
The discharging process implemented by the discharging system is described below with reference to a specific embodiment.
In this embodiment, the initial state of each valve in the discharge system is set as follows: two air inlet valves 201 are normally open, the external air valve is normally closed, the discharging control valve 301 is normally closed, the first control valve 401 is normally closed, and the pressure release valve 130 is normally closed.
After the powder tanker runs in place, the P-gear hand brake is engaged, the engine idles, the air inlet pipeline 200 is communicated with the air inlet 110 of the tank body 100 and the air outlet pipeline 300 is communicated with the material outlet 120 of the tank body 100 and the powder storage device 500, and the like, if a user triggers to start discharging in the display screen 160 and selects the air source, the display screen 160 generates a discharging instruction and sends the instruction to the controller 170.
If the air source selected by the user is an external air source, the controller 170 sends an opening instruction to the second control valve 205, the first control valve 401, and the discharge control valve 301, so that the second control valve 205, the first control valve 401, and the discharge control valve 301 are opened. If the air source selected by the user is an internal air source, the air compressor is started, and the air compressor is communicated with the pipeline between the air inlet valve 201. In this embodiment, the control procedures of the main controller 170 for the configurations of the external air source and the internal air source are interlocked, that is, the main controller 170 cannot start the air compressor and control to open the second control valve 205 at the same time, and only the external air source or the air compressor 600 supplies air to the tank 100 at the same time.
After the second control valve 205, the first control valve 401, and the discharge control valve 301 are opened in accordance with an opening command sent from the control valves, the state of the control valves, that is, whether the control valves are closed or opened, is fed back to the main controller 170.
Based on the opened second control valve 205 (or the started air compressor), the first control valve 401, the discharging control valve 301 and the two normally open air inlet valves 201, after the air enters the tank 100 through the air inlet pipe 200, the powder is fluidized, and the powder flows out from the discharge port 120 of the tank 100 and enters the powder storage device 500 through the discharge pipe 300. In the process that the powder enters the discharging pipeline 300, the gas output from the bypass pipeline 400 to the discharging pipeline 300 improves the flow rate of the powder in the discharging pipeline 300, so that the discharging speed of the powder is accelerated.
During the discharging process, the first pressure sensor 202, the second pressure sensor 206 and the third pressure sensor 140 perform pressure feedback in real time, return pressure signals to the main controller 170, and display the feedback pressure values on the display screen 160.
It is assumed that the pressure in the tank 100 and the inlet duct 200 is stabilized at 0.2MPa during normal discharge. When the pressure value fed back by the first pressure sensor 202 is 0.1MPa, the main controller 170 determines that the powder in the tank 100 is about to be discharged, and when the pressure value fed back by the first pressure sensor 202 is 0.05MPa, the powder in the tank 100 is completely discharged, the main controller 170 controls the second control valve 205, the first control valve 401 and the discharge control valve 301 to reset, and receives the self states fed back by the valve bodies; when the discharge is completed, the completion of the discharge is prompted in the display screen 160.
In the discharging system, in order to avoid an excessive pressure value, the main controller 170 ensures the safety of the system through the following control process:
if the pressure P fed back by the first pressure sensor 202 or the third pressure sensor 140 is greater than or equal to 0.23MPa, the main controller 170 sends a start instruction to the safety valve 203 to control the safety valve 203 to be opened, and the pressure is released through the opened safety valve 203;
if the pressure P fed back by the first pressure sensor 202 or the third pressure sensor 140 is greater than or equal to 0.25MPa, the main controller 170 controls to open not only the safety valve 203, but also the first control valve 401 and the discharge control valve 301, so as to accelerate the pressure relief;
if the pressure P fed back by the first pressure sensor 202 or the third pressure sensor 140 is greater than or equal to 0.28MPa, the main controller 170 controls to close the air inlet valve 201, close the second control valve 205, and open the pressure relief valve 130, so as to relieve the pressure inside the tank 100.
In this embodiment, the unloading system is further provided with an alarm device, and the main controller 170 gives an alarm, for example, an audible and visual alarm, by the alarm device according to the received pressure signal (for example, the pressure signal fed back by the first pressure sensor 202, the second pressure sensor 206, or the third pressure sensor 140) or the received signal of the state of the valve body itself fed back by each valve body is abnormal.
In the present embodiment, as shown in fig. 2, a power supply 150 is disposed in the unloading system, the power supply 150 is a 24V dc power supply 150, and the power supply 150 supplies power to the third pressure sensor 140, the first pressure sensor 202 (front and rear), the second pressure sensor 206, the controller 170, the air intake valve 201 (front and rear), the safety valve 203, the second control valve 205, the first control valve 401, the discharge control valve 301, the pressure relief valve 130, and the display screen 160 in the unloading system.
