Accompanying drawing explanation
Fig. 1 is the structural representation one of sedimeter of the present invention.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below in conjunction with accompanying drawing, the present invention is described further.
As shown in Figure 1, the sedimeter of the embodiment of the present invention includes liquid-inlet end three-way pipe 1, blow-off pipe 2, cartridge filter 3, control box 4, control line 5, import pressure measurement capillary 6, outlet pressure measurement capillary 7, liquid outlet end three-way pipe 8, differential pressure pickup 9, main channel switch 100, scum cock 200, bypass passageways switch 300, in the present embodiment, main channel switch 100, scum cock 200 and bypass passageways switch 300 all adopt motor-driven valve.During assembling, the port one 2 of liquid-inlet end three-way pipe 1 is connected with the inlet port 31 of cartridge filter 3 by main channel switch 100, and the outlet 38 of cartridge filter 3 is connected with the port 81 of liquid outlet end three-way pipe 8; The sewage draining exit 37 of cartridge filter 3 is connected with blow-off pipe 2 by scum cock 200; The port one 3 of liquid-inlet end three-way pipe 1 by the port 82 of bypass passageways switch 300 and liquid outlet end three-way pipe 8 together with; The inlet pressure of cartridge filter 3 detect mouth 310 with import pressure measurement capillary 6, differential pressure pickup 9, export pressure measurement capillary 7, cartridge filter 3 outlet pressure detects mouth 39 and is connected successively; Control box 4 is connected with main channel switch 100, scum cock 200, bypass passageways switch 300 and differential pressure pickup 9 respectively by control line 5, forms electric control loop.Particularly, cartridge filter 3 comprises cartridge filter cylindrical shell 32, is arranged on the end cap 33 of the entrance point of cylindrical shell 32, the filtration core 34 be arranged in cartridge filter 3, is arranged on the flange 35 that cartridge filter 3 cleans end.Signal processor and other electric components have been installed in control box 4, be used for processing the signal of differential pressure pickup 9, and open or close main channel switch 100, bypass passageways switch 300, scum cock 200 according to certain logic, make cartridge filter carry out filtration cycle and automatic pollution discharge cleaning according to set logic.
The present invention is installed on the pipeline of fluid circulation system, liquid in the circulatory system is entered by entrance point three-way pipe 1, during normal work, main channel switch 100 is in open mode, and bypass passageways switch 300, scum cock 200 are in closed condition, now, liquid will enter cartridge filter 3, and the filtration core 34 that the various foreign material existed in liquid are filtered in cylinder 3 filters down, and is collected in filtration core, clean liquid is then discharged from cartridge filter 3, enters into system equipment by the circulatory system.
During operation, the pressure reduction of differential pressure pickup 9 incessantly between the inlet pressure of tracer liquid and outlet pressure, along with the foreign material gathered in filtration core 34 increase, this pressure reduction can be increasing, when pressure difference reaches default startup blowdown pressure reduction, bypass passageways switch 300 is opened by electric control loop by control box 4, and main channel switch 100 cuts out, and scum cock 200 is opened.Circulating fluid now no longer flows through filter cylinder 3, but continues to keep uninterrupted circulation by bypass passageways.And be greater than atmospheric pressure due to the pressure of liquid system, under system pressure, a part of circulating fluid will pass over filter core 34 conversely, is outwards discharged by blowoff valve 4, be collected at foreign material in filtration core 34 then along with the liquid of this part discharge is rinsed out, filtration core 34 recovers clean.Then, when pressure reduction between the inlet pressure and outlet pressure of differential pressure pickup 9 tracer liquid is varied down to reasonable number, control box 4 closes scum cock 200, opens main channel switch 100, close bypass passageways switch 300, the normal circulation that liquid will return to by cartridge filter.
Filter cartridge outlet shutoff valve 400 is provided with between the outlet 38 of cartridge filter 3 and liquid outlet end three-way pipe 8, the effect of filter cartridge outlet shutoff valve 400 is then, under normal circumstances, it is normally open, but, if there is the Severe blockage of filtration core 34, clean dirt can not be discharged completely according to the recoil blowdown of process above, filtration core 34 is cleaned up, then now can open bypass passageways switch 300, close main channel switch 100 and filter cartridge outlet shutoff valve 400, liquid keeps circulation by bypass passageways, and now can take the cleaning end flanges 35 of cartridge filter 3 apart, filter core 34 is taken out, discharge dirt or more renew cartridge.
Flange 35 and cylindrical shell 32 are provided with sealing ring 36 between cleaning and holding, and sealing ring 36 can increase the sealing property between flange 35 and cartridge filter 3.
The present invention can automatically detect in real time at the stopping state of filter, the blocking of Timeliness coverage filter; Automatically automatic pollution discharge cleaning can be carried out without the need to manual intervention to the dirt filtered down; Under any circumstance, can system cloud gray model be remained, need not in order to blowdown or more renew cartridge and shutdown system; Automation and intellectuality, and can network mutually with the upper monitoring of the circulatory system.
The above is the specific embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
