Hour is run with same state, runs the long-term high current of roots blower, the serious waste energy, meanwhile, the filter bag of deduster
Due to the protection of no safe pressure, roots blower is set to be lost with filter bag big, service life is short.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of sack cleaner deashing Stress control section
Can device.According to the operating pressure of deduster running status adjust automatically roots blower, both energy-conservation, extended roots blower and filter again
The service life of bag.
In order to achieve the above object, the utility model is realized using following technical scheme：
A kind of sack cleaner deashing Stress control energy-saving appliance, including compressed air main pipeline and with compressed air main pipeline
Three exhaust charge roads being connected, wherein, magnetic valve one is set on first exhaust charge road, in Article 2 exhaust charge
Magnetic valve two and safety valve three are set on road, safety valve four is set on Article 3 exhaust charge road；
First exhaust charge road is operated in deduster and is stopped state, and Article 2 exhaust charge road, which is operated in, to be removed
Pressure difference deashing working condition in dirt device, Article 3 exhaust charge road is operated in deduster High Pressure Difference working condition；
Described compressed air main pipeline one end is connected with the roots blower pipeline of dust pelletizing system, and the other end passes through air accumulator
Access deduster deashing pressure piping；
First exhaust charge road is connected by magnetic valve one with air；
The Article 2 exhaust charge road is connected by magnetic valve two and safety valve three with air；
The Article 3 exhaust charge road is connected by safety valve four with air；
The pressure set points of safety valve three are 0.08MPa, and the pressure set points of safety valve four are 0.095Mpa.
The magnetic valve one and magnetic valve two are controlled and by deduster operating pressure value by the PLC of dust pelletizing system
Control.
Compared with prior art, the beneficial effects of the utility model are：
1st, when deduster is stopped, magnetic valve one, which is connected, make it that compressed air main line is emptied to air, Luo Cifeng
Machine is in zero pressure working condition, and blower motor is in energy-saving operation state；
2nd, when deduster is operated in middle pressure differential condition, magnetic valve two is connected with safety valve three, and roots blower, which is in, to be compared
The state operation of energy-conservation；
3rd, when deduster is operated under High Pressure Difference state, safety valve four is connected, and roots blower is in the state of relative energy-conservation
Operation；
4th, by PLC control, according to the operating pressure of deduster running status adjust automatically roots blower, both may be used
To ensure ash-removal effect of the deduster under High Pressure Difference state, the loss of roots blower and filter bag can be mitigated again, extending it makes
Use the life-span.

Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of sack cleaner deashing Stress control energy-saving appliance, including compressed air main pipeline (1) and with
Three exhaust charge roads that compressed air main pipeline is connected, wherein, magnetic valve one is set on first exhaust charge road
(2) magnetic valve two (3) and safety valve three (4), are set on Article 2 exhaust charge road, set on Article 3 exhaust charge road
Safety valve four (7)；
First exhaust charge road is operated in deduster and is stopped state, and Article 2 exhaust charge road, which is operated in, to be removed
Pressure difference deashing working condition in dirt device, Article 3 exhaust charge road is operated in deduster High Pressure Difference working condition；
Described compressed air main pipeline one end is connected with the roots blower pipeline of dust pelletizing system, and the other end passes through air accumulator
Access deduster deashing pressure piping；
First exhaust charge road is connected by magnetic valve one (2) with air；
The Article 2 exhaust charge road is connected by magnetic valve two (3) and safety valve three (4) with air；
The Article 3 exhaust charge road is connected by safety valve four (7) with air；
Described (4) pressure set points of safety valve three are 0.08MPa, and safety valve four (7) pressure set points are 0.095Mpa.
As shown in Fig. 2 the magnetic valve one (2) and magnetic valve two (3) by dust pelletizing system PLC control and by
Deduster operating pressure value is controlled.
The control process of the sack cleaner deashing Stress control energy-saving appliance is as follows：
1) when deduster is operated in less than 600Pa, deduster stops deashing, and magnetic valve one (2) coil (5) obtains electric, electromagnetism
Valve one (2) is opened, and compressed air is to airborne release, and roots blower works in the power save mode of zero pressure；
2) when deduster running status is higher than 600Pa, magnetic valve one (2) is closed；When deduster is transported less than 1000Pa
During row, magnetic valve two (3) is in open mode, and magnetic valve two (3) magnet coil (6) obtains electric, and safety valve three (4) work makes clear
Grey Stress control works in compared with energy-conservation in 0.08MPa and damages less compared with power save mode to filter bag；
3) when deduster operates in more than 1000Pa, magnetic valve one (2), magnetic valve two (3) are turned off, safety valve three
(4) arrival end is closed, and stops exhaust, and only safety valve four (7) works, and makes deashing Stress control in 0.095MPa, soot cleaning system
Work in the stronger state of deashing ability.
The utility model can both ensure ash-removal effect of the deduster under High Pressure Difference state, can be in again in deduster
The state for making roots blower be in relative energy-saving in the case of middle equal-pressure-difference is run, while ash-removal effect is ensured, is reduced clear
The damage that grey compressed air is washed away energetically to filter bag, extends the service life of filter bag while energy-conservation, when deduster is in small
When 600Pa state operation, roots blower is run under the zero load state of most energy-conservation, (roots blower is negative not in having
Shut down under lotus state, also do not allow frequent starting).Thus reach according to deduster running status adjust automatically roots blower
Operating pressure, reaches both energy-conservations, extends the purpose of roots blower and life of bag filter again.
Above example is implemented lower premised on technical solutions of the utility model, gives detailed embodiment
With specific operating process, but protection domain of the present utility model is not limited to the above embodiments.Side used in above-described embodiment
Method is conventional method unless otherwise instructed.
