Abstract
The utility model discloses a rotatory shell and tube back flush filter, including 8 filters with locate the cavity in and have rotatory mouthful rotary valve, be equipped with the filter core in the filter, around the filter evenly is fixed in the pressure manifold, the pressure manifold is connected with the export, is provided with positioning system on the rotary valve, and the rotary valve links to each other with the drain that is equipped with the quck -opening valve through the pipe, is equipped with import and manual drain on the cavity, and the filter element of filter adopts the metal to carve shape winding silk screen, and the rotatory mouth of rotary valve is equipped with the sealed interface of independent elasticity, and positioning system adopts and is positioned the operation that automatic re -setting combined together, the utility model discloses a filter element adopts the metal to carve shape winding silk screen, reduces the loss of pressure when filtering, the easy washing, and automatic back flush filter element under the condition that the system does not stop reduces product cost, and the unit capacity increase can increase filter unit under less investment, reduced a large amount of valves, has increased the reliability and the practicality of system, the simple operation.
Description
Technical field
The utility model relates to a kind of filter, particularly relates to a kind of rotary array-pipe formula backwash filter.
Background technology
Rotary array-pipe formula backwash filter is a kind of uninterrupted by technological process of in-line arrangement, gum level increases (minimizing) filter element, multi-functional, the multi-form filtering product of the one of controlled investment cost.It is applicable to from gasoline to heavy coker gasoline, diesel oil and residual oil, sewage and other require the flowing material of purified treatment, effectively ensure the equipment on pipeline and on device, stop blocked and reduce the possibility in service life, possess and rinsed thoroughly, the performances such as sump oil amount is few, automaticity is high, thus avoid adopting fixed filter frequently need dismantle filter because of impurity buildups, washing and filtering element and replacing damage the economic loss of filter screen.
Backwash filter of the prior art, many employings manual backwashing filter device, it considerably increases the labour intensity of labor, due to system pressure fluctuation, when inlet pressure reduces, liquid outlet fluid pressure comparatively inlet is high, and high pressure liquid flows out to the outside inside filter core, filter core bulge phenomenon can be produced, greatly reduce the service life of filter core.
Utility model content
For solving the problem, the utility model provides a kind of rotary array-pipe formula backwash filter.
The technical solution adopted in the utility model is:
Rotary array-pipe formula backwash filter, comprise filter and to be located in cavity and with the rotary valve rotating mouth, filter core is provided with in described filter, described filter is evenly fixed on header surrounding, described header is connected with outlet, described rotary valve is provided with navigation system, and described rotary valve is connected with the sewage draining exit being provided with quck-opening valve by pipe, and described cavity is provided with import and manual blowdown mouth.
Described filter has 8, and the filter element of described filter adopts metal wedge to be wound around silk screen, and the rotation mouth of described rotary valve is provided with independently elastic packing interface, and described navigation system adopts and is positioned the mode of operation combined that automatically resets.
The utility model has the advantages that: the filter element of filter adopts metal wedge to be wound around silk screen, filter core has high intensity and durability, significantly reduce pressure loss during filtration, extend filtration time, reduce maintenance expense, and easy cleaning, automatic back flush filtration element under system ceaselessly situation, reduce unplanned shutdown, reduce product cost, there is programme-control, stable performance, reliable operation, unit capacity increase can increase filter element under less investment, technological requirement can be met, decrease a large amount of valves, only replace valves a large amount of in traditional tube filter with a rotary valve, add reliability and the practicality of system, single filter adopts unique quick-opening structure, maintenance can not carried out to filter core by any instrument, the rotation mouth of rotary valve adopts independently elastic packing interface, rotary valve can be effectively avoided to wear and tear the leakage caused, rotate navigation system and adopt location and the mode combined that automatically resets, can operate time auto-alignment rotate each outlet.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is top view of the present utility model.
Wherein: 1, filter; 2, filter core; 3, rotary valve; 4, header; 5, export; 6, navigation system; 7, quck-opening valve; 8, sewage draining exit; 9, import; 10, pipe; 11, manual blowdown mouth; 12, mouth is rotated; 13, cavity.
Detailed description of the invention
Rotary array-pipe formula backwash filter, comprise filter 1 and to be located in cavity 13 and with the rotary valve 3 rotating mouth 12, filter core 2 is provided with in filter, filter is evenly fixed on header 4 surrounding, header is connected with outlet 5, rotary valve is provided with navigation system 6, rotary valve is connected with the sewage draining exit 8 being provided with quck-opening valve 7 by pipe 10, cavity is provided with import 9 and manual blowdown mouth 11, filter has 8, the filter element of filter adopts metal wedge to be wound around silk screen, the rotation mouth of rotary valve is provided with independently elastic packing interface, navigation system adopts and is positioned the mode of operation combined that automatically resets.
The import and export of filter are furnished with two pressure transmitters, and when the differential pressure of filter reaches setting value, it exports 4 ~ 20m signal to PLC or DCS, carries signal, the filter that will be rinsed by rotary valve rotary alignment by PLC or DCS configuration to on-the-spot rotary valve.During backwash, changeover valve turns to the position of next filter, and the filter cylinder rinsed is aimed in the outlet of rotary valve, then opens backwash outlet valve fast, is washed away by the foul on corresponding filter core.Time delay certain hour, rotary valve forwards the next position to again, and then opens backwash outlet valve fast, is washed away by the foul on corresponding filter core, analogizes in proper order, until rinsed all filters.After backwash, the pressure reduction of system returns to normal operating conditions, and backwash terminates.Until restart backwash when next backwash signal comes.
The filter element of the utility model filter adopts metal wedge to be wound around silk screen, filter core has high intensity and durability, significantly reduce pressure loss during filtration, extend filtration time, reduce maintenance expense, and easy cleaning, automatic back flush filtration element under system ceaselessly situation, reduce unplanned shutdown, reduce product cost, there is programme-control, stable performance, reliable operation, unit capacity increase can increase filter element under less investment, technological requirement can be met, decrease a large amount of valves, only replace valves a large amount of in traditional tube filter with a rotary valve, add reliability and the practicality of system, single filter adopts unique quick-opening structure, maintenance can not carried out to filter core by any instrument, the rotation mouth of rotary valve adopts independently elastic packing interface, rotary valve can be effectively avoided to wear and tear the leakage caused, rotate navigation system and adopt location and the mode combined that automatically resets, can operate time auto-alignment rotate each outlet.
