Abstract
The utility model discloses multiple-unit self-cleaning filter, at least three vertical filters have been mounted side by side in the centre of a rectangle stand type support, a recovery tube for connecting respectively is horizontally installed with each filter bottom liquid outlet in support side, a feed pipe for connecting with each filter bottom inlet respectively is horizontally installed with recovery tube underlying holder, a blow-off pipe for connecting with each filter bottom inlet respectively is horizontally installed with the support below feed pipe, a blowoff valve is separately installed between the inlet of blow-off pipe and each filter bottom, a liquid feed valve is separately installed between the inlet and blow-off pipe of each filter bottom.This utility model is connected in parallel with multiple self-cleaning filters, and install pressure reduction variator additional between the turnover mouth of pipe of each filter element, can each filter element of effective control normal filtration or carry out backwash, high with filter efficiency, the uninterrupted advantage for filtering, reducing maintenance cost.
Description
Technical field
This utility model be a kind of suitable for the fields such as petrochemical industry, medicine, water source and industrial circulating water use how single
First self-cleaning filter.
Background technology
Existing well strainer, although with good filtration effect, the little advantage of resistance, be widely used in petrochemical industry,
The filtration in the fields such as medicine, water source, industrial circulating water, but as filter area is little, pollutant holding capability is little, is easily blocked by dirt, clearly
Wash work complicated, it is necessary to which dismounting being carried out to equipment could clean to filter element, affect work efficiency.
Content of the invention
The purpose of this utility model is to provide one kind and can effectively improve filter efficiency, does not affect normal work in cleaning
Multiple-unit self-cleaning filter.
The technical solution of the utility model is completed in the following manner, multiple-unit self-cleaning filter, it is characterised in that：
At least three vertical filters have been mounted side by side in the centre of a rectangle stand type support, one have been horizontally installed with support side
The recovery tube that root is connected with each filter bottom liquid outlet respectively, be horizontally installed with recovery tube underlying holder one respectively with
The feed pipe of each filter bottom inlet connection, be horizontally installed with the support below feed pipe one respectively with each filtration
The blow-off pipe of device bottom liquid inlet mouth connection, is separately installed with a blowdown between the inlet of blow-off pipe and each filter bottom
Valve, is separately installed with a liquid feed valve between the inlet and blow-off pipe of each filter bottom.Install in the opposite side of support
One switch board, switch board can be mounted to CPU automatic control cabinets or Pneumatic control cabinet and its corresponding control unit as needed
Part, each filter import and export and sewage draining exit set up an automatic ball valve respectively, between total turnover mouth of pipe of filter
Install pressure reduction variator additional.
This utility model is connected in parallel with multiple self-cleaning filters, and is added between the turnover mouth of pipe of each filter element
Dress pressure reduction variator, can each filter element of effective control normal filtration or carry out backwash, high with filter efficiency, uninterruptedly
Filter, reduce the advantage of maintenance cost.
Description of the drawings
Fig. 1 is structural representation of the present utility model；Fig. 2 is the mounting structure of any one filter in each filter element
Schematic diagram；Fig. 3 is operation principle schematic diagram of the present utility model.
Specific embodiment：
Embodiment is described in detail in conjunction with accompanying drawing, this utility model is to pacify in the centre of a rectangle stand type support 1 side by side
Equipped with least three vertical filters 5, one is horizontally installed with support side and is connected with each filter bottom liquid outlet 4 respectively
Recovery tube 6, be horizontally installed with a feed flow for connecting with each filter bottom inlet 3 respectively on recovery tube underlying holder
Pipe 7, is horizontally installed with a blow-off pipe 10 for connecting with each filter bottom inlet respectively on the support below feed pipe,
A blowoff valve 9 is separately installed between the inlet of blow-off pipe and each filter bottom, in the feed liquor of each filter bottom
A liquid feed valve 8 is separately installed between mouth and blow-off pipe.One switch board 2, control can also be installed in the opposite side of support
Cabinet can be mounted to CPU automatic control cabinets or Pneumatic control cabinet and its corresponding control element as needed, in each filter
Import and export and sewage draining exit set up an automatic ball valve respectively, install pressure reduction variator additional between total turnover mouth of pipe of filter.
The filtration and backwash of each filter can be individually controlled, is allowed to be independent of each other, keep uninterruptedly being filtered.Its work is former
Reason is：During normal work, the imported valve of filter is opened, and blowoff valve cuts out, and filter medium enters filter housings from bottom
Interior, after filter element filtering, then enter housing internal upper part reclaim through liquid outlet, return to subsequent processing.Impurity in liquid is filtered
Core is intercepted, and when the impurity of cartridge surface forms filter cake, the pressure reduction of import and export gradually rises, when the differential reaches a set point, control
System processed according to programme output signal, close by the imported valve, and sewage draining valve is opened, and carries out backwash to the filter,
During backwash, the filter of other each filter units has been at normal operating conditions to the filter.The filter is anti-
After flushing, you can close blowoff valve, beat liquid feed valve, carry out normal filtration.
