6) spraying liquid shower nozzle 7
Under normal circumstances, atomizer 7 or general Fan spray head 7 can be selected according to fluid flow size spraying liquid shower nozzle 7.
7) controller 9
Wherein, controller 9 is such as PLC (Programmable Logic Controller: programmable logic controller (PLC) 9), can realize controlling the multiple difference of device by controller 9, being introduced wherein will be enumerated below, certainly, in specific implementation process, be not limited to following several situation.
1. controller 9, specifically for:
When the position of material shows that the amount of material is less than the first predetermined amount, regulating gate 3 is in closed condition.
For example, controller 9 can obtain the position of the material that level-sensing device 2 detects immediately, and then determine the amount of material, when the amount of material is less than the first predetermined amount, then illustrate that the amount of material is lower, in this case, controller 9 can send predetermined pulse information to gate 3, and then regulating gate 3 is in closed condition; In addition, if this device comprises display, can also also can low material level and send warning message at display screen.
2. controller 9, specifically for:
When the position of material shows that the amount of material is positioned at preset range, regulating gate 3 is in the first opening, and then material enters master stream by gate 3 and claims room 4;
Obtain the mass flow that flowmeter detects, and judge whether mass flow is greater than the first preset flow, when mass flow is greater than the first preset flow, regulating gate 3 enters the second opening, and the discharge quantity of the second opening is less than the discharge quantity of the first opening.
For example, comprise high material in this device and example counted by low material, if when material is between high material meter and low material meter, then illustrate that the amount of material is positioned at preset range, if the amount of material is in preset range, then illustrate that the material in finished bin 1 belongs to normal category.
So in this case, then can be in opening by regulating gate 3, and gate 3 is opened to larger discharge quantity, Figure 2 shows that example, then the first opening corresponding high flow capacity gear I is in opening;
Then controller 9 continues the mass flow obtaining flowmeter detection, if mass flow is not more than the first preset flow, then illustrates that flow is comparatively normal, so keep gate 3 to be in the first opening; If mass flow is more than the first preset flow, then illustrate that flow is comparatively large, so regulating gate 3 and then the second opening, Figure 2 shows that example, then the second opening corresponding low discharge gear II, and then reduce the discharge quantity of gate 3, to reduce the mass flow that flow measuring unit detects.
Further, controller 9, also for:
After regulating gate 3 enters the second opening, judge whether mass flow is less than the second preset flow, when mass flow is less than the second preset flow, regulating gate 3 enters the first opening.
For example, after regulating gate 3 enters the second opening, controller 9 still continues to obtain mass flow, if mass flow is greater than the second preset flow, then illustrates that mass flow is normal, so keep gate 3 to be in the second opening; If mass flow is less than the second preset flow, then illustrates that mass flow is lower, so need gate 3 to be adjusted to the second opening from the first opening, to improve discharge quantity, and then improve mass flow.
3. controller 9, specifically for:
Obtain the position of the material that level-sensing device 2 detects;
Whether the amount according to the position judgment material of material is less than the first predetermined amount;
When the amount of material is less than the first predetermined amount, regulating gate 3 is in closed condition;
When the amount of material is greater than the first predetermined amount, obtain the mass flow that flowmeter detects;
Based on the unlatching gear of mass flow determination gate 3.
For example, PLC is power-up initializing first, and detection comprises material level, airline pressure, fluid path pressure and master stream and claims to measure communication, if there is fault, and output alarm, gate 3 keeps closed condition; If do not have fault, carry out next step action, also namely controller 9 continues the position obtaining the material that level-sensing device 2 detects, then determine the amount of material based on this, if the amount of material is less than the first predetermined amount, then illustrate that material is less, so in this case, regulating gate 3 is in closed condition.
And if the amount of material is greater than the first predetermined amount, then illustrate that the amount of material is sufficient, in this case, in order to realize the control to gate 3 more accurately, then first can obtain the mass flow that flowmeter detects, the then opening of mass flow regulating gate 3.
In addition, controller 9, after acquisition mass flow, can also determine the fluid flow of spraying liquid shower nozzle 7 by mass flow, then by the pulse signal of the shower nozzle 7 of adjustment spraying liquid shower nozzle 7, controls fluid flow.
Finally, if finished bin 1 material level is shown as low material level, or setting output completes, and whole spraying process terminates, and controller 9 notice gates 3 are closed automatically.
As further preferred embodiment, please continue to refer to Fig. 1, device also comprises:
Solenoid valve box 5, flowmeter is connected with solenoid valve box 5, and solenoid valve box 5 inside is provided with Pressure gauge and magnetic valve, and Pressure gauge for detecting airline pressure and fluid path pressure, and sends it to controller 9; Magnetic valve one end is connected to the input of spraying liquid shower nozzle 7, and the other end is connected to liquid and enters pipeline, and when magnetic valve is in conducting state, the liquid that liquid enters in pipeline can enter spraying liquid shower nozzle 7 by magnetic valve; When magnetic valve is in cut-off state, the liquid that liquid enters in pipeline cannot enter spraying liquid shower nozzle 7.
As further preferred embodiment, please continue to refer to Fig. 1, device also comprises:
Electric cabinet 6, controller 9 is arranged in electric cabinet 6, and be also provided with in electric cabinet 6 and controller 9 is connected to level-sensing device 2, gate 3, flowmeter and each coupling assembling manometric and display, display can show parameters and warning message in real time.
