Description
Technical field
The utility model belongs to chemical industry equipment field, specifically relates to a kind of filter of exempting from for a long time to clear up.
Background technology
In the industry production such as chemical industry, food, medicine, in part cooling water, sewage, be mixed with various particles, suspension, equipment lining, filler, Polypropylence Sheet of entering water system etc. even come off, these suspensions and foreign material enter after water system, accumulate for a long time and easily cause equipment, line clogging, have a strong impact on production run, even to equipment, bring grievous injury.The for example remained ammonia in coal chemical enterprise and recirculated water, in the former, contain a large amount of oil slick and coke powder coal dust suspension, when entering heat transmission equipment, because of reason impurity meeting sedimentations such as flow velocity reductions, progressively accumulation causes passage to reduce or stops up, and greatly affects even equipment stoppage in transit of heat transfer effect; The latter moves because cooling rack opens wide, have a large amount of dust, leaf even the impurity such as polybag waft into, impurity can deposit obstruction while entering the meticulous heat exchange facilities such as heat pump, heat pipe with water, cause equipment badly damaged, cannot normally move, when serious, can cause system shutdown, to enterprise, bring huge economic loss, therefore need in technique, increase and filter link.And conventional " Y " is although type filter etc. can play filter effect, too much because of impurity in water, filter needs frequent dismounting cleaning, still can have a strong impact on production run.For addressing the above problem, spy provides a kind of new technical scheme.
Utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of simple in structure, application convenience is provided, and does not need the filter that can remove impurity in water of frequent cleaning.
The technical scheme that the utility model adopts is:
Exempt to clear up a filter, comprise the airtight container being formed by cylindrical shell and upper and lower cylinder cover, it is characterized in that,
Described cylindrical shell one middle side part is provided with charging aperture, described cylindrical shell top or opposite side top are provided with discharging opening, in discharging opening, be provided with recoil tube and a water spout that extends to screen pack, described cylindrical shell bottom is provided with sewage draining exit, one end that described discharging opening is positioned at cylindrical shell is provided with screen pack, the external valve of described charging aperture and discharging opening place, described sewage draining exit place is provided with blowdown control valve, in described cylindrical shell, be provided be oppositely arranged with charging aperture for making charging aperture and discharging opening avoid directly relative arc-shaped partition, between described arc-shaped partition and cylinder inboard wall, form an elliptical region, between described arc-shaped partition and lower shell lid, be provided with gap.
Further, on described cylindrical shell, have inspection manhole, inspection manhole is detachable, utilizes connector nut to connect.
Further, for convenience of blowdown, the bottom of lower shell lid is taper.
Further, shown in screen pack be the cage structure that the reinforcing bar by warp-wise and broadwise forms, and the outside of cage shape skeleton is coated with screen pack, described screen pack upper portion is in discharge nozzle, lower portion is in cylinder lumen.
Further, described screen pack is the embedded mouth of pipe place that is arranged on discharging opening, and uses securing member fastening between screen pack and the tube wall of discharging opening.
The utility model compared with prior art has obvious beneficial effect: from above scheme, charging aperture is at cylindrical shell middle part, and discharging opening, on cylindrical shell top or top, filters rear impurity crystallizing field at cylinder body bottom, because of impurity in material more, net to be filtered can adopt recoil measure that impurity on filter screen is come off after stopping up, and enters the impurity sedimentation district of cylindrical shell, in decanting zone, deposit, decanting zone can hold more impurity, also can when operation, carry out blowdown, removes former filter from and frequently dismantles cleaning.For the impurity that prevents from coming off enters charging aperture, and the flushing to impurity while reducing charging, dividing plate is set in cylindrical shell.The utility model is simple in structure, easy to use, and good filtration effect does not need equipment frequently to dismantle, and has reduced labour intensity, has improved utilization rate of equipment and installations, easy to operate, durable in use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram of backwash of the present utility model.
Fig. 3 is the schematic diagram of screen pack.
Wherein: 1 cylindrical shell, 2 feed pipes, 3 discharge nozzles, 4 blow-off pipes, 5 backwash water pipes, 6 water spouts, 7 screen packs, 8 inspection manholes, 9 dividing plates, 91 gaps, the 92 sewage mouth that raises up, 10 gate valves.
The specific embodiment
Below in conjunction with accompanying drawing 1 and Fig. 3 and preferred embodiment, the filter specific embodiment, structure, feature and effect thereof to according to the utility model proposes, be described in detail as follows.
A kind of dismounting cleaning filter of exempting from, comprise that bottom is for convenience of the cylindrical shell 1 of the taper of blowdown shape, it is the space that sewage collects, cylindrical shell 1 one middle side parts are provided with feed pipe 2, for charging aperture, the outside of feed pipe 2 is by flange connections road and gate valve 10, and cylindrical shell 1 top (opposite side top) establishes discharge nozzle 3, for the discharging opening of the sewage after filtering, discharging opening pipe top connecting pipe and gate valve 10.In cylindrical shell 1 conical lower portion, establishing blow-off pipe 4, is the passing away of mud, sewage draining exit, blow-off pipe 4 place pipelines top connecting pipe and gate valve 10.On discharging tube wall, through a backwash water pipe 5, backwash water pipe 5 is downward bending 90 degree in discharging opening, and extend to screen pack place, and a water spout 6 is installed, and control respectively gate valve 10 or valve on charging and discharging pipe and blow-off pipe.The embedded impurity arranging on the discharge nozzle screen pack 7 that easily recoil comes off, is convenient for changing and overhauls, and adopts trip bolt to carry out fastening.Its structure can be with reference to shown in figure 3, integral body is the cage structure being comprised of the reinforcing bar through broadwise, and the outside of cage shape skeleton is coated with screen pack, and upper end is fixed disk, be fixed on discharge nozzle, wherein the material of screen pack and model can be selected according to needed occasion.Inspection manhole 8, for the maintenance of equipment, is flange arrangement, is arranged on barrel one side.In cylindrical shell 1, be provided with dividing plate 9, dividing plate is the dividing plate of an arc, be connected with barrel soldering, in bottom, be provided with a gap 91, can be for the lower row of dirt, upper end is that sewage raises up mouthfuls 92, and sewage upper reaches, and turn back downwards by screen pack 7, in the process of turning back, backflow slows down, and heavier dirt drops to the settling zone of cylinder body bottom in the effect of deadweight.
While needing backwash, the dirt inherent filtration net in screen pack directly falls, and avoids flowing to charging aperture, charging aperture is formed to a protection, as shown in Figure 2.
In sum, this device structure is simple, easy to use, and good filtration effect does not need frequently filter screen to be carried out to disassembly, cleaning, has reduced labour intensity, has improved utilization rate of equipment and installations, has reduced environmental pollution, easy to operate, durable in use.
