Description
Technical field
The utility model belongs to Management of Pipeline Mechanical Equipment utensil field, relates in particular to a kind of small-sized visual self-cleaning filter for chemical process pipeline.
Background technology
Filter is mounted in a kind of filter on pumped (conveying) medium pipeline.At present, the minifilters of the process pipelines in Some Domestic chemical plant configuration still adopts y-type filter or T-shaped straight-through type filter.Due to this minifilters, be mostly arranged on the import of the precision equipments such as etchant solution Agitation Tank, reactor import and export and pump, magnetic valve, be used for the ducted impurity of filtering technique and crystalline solid thereof, be therefore not easy to often dismounting and clean.In addition this process pipelines flow and caliber parameter are all less, select traditional standard small filter, in use, because filter area is less, often there is filtering bad situation about even stopping up, before each Chemical Manufacture, all need manual teardown, screen pack is taken out and cleaned from cartridge filter, after cleaning, reinstall in cartridge filter, not only waste time and energy, increased the personnel's that clean labour intensity, and bring inconvenience to Chemical Manufacture and working service, directly affected production efficiency.
Summary of the invention
The utility model aims to provide a kind ofly can directly observe filtration situation, realizes not dismantling at any time and cleans, thereby avoid the visual self-cleaning filter that stops up.
For this reason, the solution that the utility model is taked is:
A kind of visual self-cleaning filter, comprise inlet tube and outlet that screen pack, T-shape through type cartridge filter and barrel bilateral symmetry arrange, it is characterized in that, in uncovered cartridge filter upper end, be bolted the ring flange of middle with hole, between ring flange and cartridge filter, lay Gask-O-Seal, on the interstitial hole circumference of ring flange and annular gland, be respectively equipped with a circle draw-in groove, in draw-in groove, be inlaid with visor sheet, on visor sheet, below portion is equipped with sealing ring, and visor sheet is by gland above and be bolted on ring flange; In cartridge filter side wall upper part, be provided with threaded connection hole, connecting hole inside and outside is threaded connection respectively scavenge pipe, and the scavenge pipe port of export in cartridge filter is equipped with shower nozzle, and the scavenge pipe other end that is positioned at cartridge filter outside connects high-pressure water pipeline by high-pressure ball valve; Cartridge filter filtering net bottom is with frusto-conical barrel, frusto-conical barrel lower end is with positioning pipe, cartridge filter Tong Di center is provided with link slot, positioning pipe is inserted at the bottom of cartridge filter cylinder in link slot, below link slot, lead to and have sewage draining exit, sewage draining exit is threaded connection blow-off pipe, and ball valve is housed on blow-off pipe.
Described scavenge pipe axis and cartridge filter axes intersect, between scavenge pipe axis and inlet tube axis, angle is 30 °～60 °.
Described sealing ring is asbestos rubber circle.
Described visor sheet is tempering Pyrex sheets.
Described screen pack is stainless (steel) wire.
Self-cleaning process of the present utility model and beneficial effect are:
When needs clean, close cartridge filter inlet tube and outlet, open scavenge pipe high-pressure ball valve and blow-off pipe ball valve, water under high pressure or cleaning fluid are ejected on the screen pack of cartridge filter bottom by scavenge pipe outlet nozzle, screen pack is cleaned, and after cleaning, waste water or waste liquid are discharged through filter cylinder lower end blow-off pipe.Without cleaning when the normal filtration state, close scavenge pipe high-pressure ball valve and blow-off pipe ball valve, open cartridge filter inlet tube and outlet, process fluid enters cartridge filter by inlet tube, can flow out from outlet after filtration after net filtration.The situation of filter interior filtering flow situation and cleaning filter thereof can be observed by filter top visor.
The utility model can be realized self-cleaning without dismounting filter, convenient and swift, time saving and energy saving, can save scavenging period, alleviates cleaning personnel labor intensity, enhances productivity simultaneously.Simultaneously, when normal filtration state and cleaning, all can directly observe process fluid filtration condition and cleaning situation in cartridge filter by filter top visor, and according to impurity in screen pack and crystalline solid, gather situation and determine whether to clean and scavenging period, thereby effectively prevent plugged filter phenomenon, improve filter effect, reduce cleaning and maintenance workload.
