Description
Technical field
The utility model relates to a kind of automatic dirt-removing filtering device.
Background technology
Filter is widely used in the collection of solid impurity particle in fluid conveying.Such as, but plain filter, Y-filter, must to remove contamination to filter screen by manually to uncap after filter net jam, because inspection of uncapping causes valve rear line to be stopped transport, increase maintenance man-hours.CN201420088726.0 discloses a kind of automatic dirt-removing filtering device (Fig. 1), include main casing 1, water-in flange 2 and water-output flange 3, also include a housing 4, blowdown flange 5, water inlet transmitter 6, delivery port transmitter 7, screen pack 8, motor-driven valve 9 and switch board 10, described housing is along the water inlet direction of water inlet to delivery port lopsidedness, the rear end of propping up housing is connected with main casing, a housing side inwall and main casing inwall intersection are being provided with screen pack, the front end of housing is provided with blowdown flange, blowdown flange is provided with motor-driven valve, water inlet and the water outlet of described main casing are respectively arranged with the water inlet transmitter and delivery port transmitter that are connected with main casing, described water inlet transmitter, delivery port transmitter is electrically connected with switch board by wire 11 mutually with motor-driven valve, its can be real realize Automated condtrol, the filter course of work can detect automatically, and can judge voluntarily, the sewage filtering equipment of automatic pollution discharge, but magnetic valve must be relied on to perform blowdown action, needs installing cables.CN201420139617.7 discloses a kind of fast interface drain filter (Fig. 2), and it is arranged in liquid medium delivery pipeline system, and its position is usually located at pressure-reducing valve, relief valve, the entrance point of Valve for keeping constant water level or other equipment, this filter is mainly by triple-valve body 1, snout cavity 11, outlet plenum 12, blowdown chamber 13, valve gap 2, valve pocket 21, Compress Spring 3, spool 4, inner chamber 41, mudhole 42, O type circle 43, circlip 44, antifouling cover 5, gasket seal 6, the formations such as actinal surface packing ring 7 and screen tube 8, this spool can move axially along valve gap axial line and spacing, and spool moves axially in process to possess and connects fast and self-sealing function, thus achieving opening fast and automatically closing of filter dirt eliminating function, this drain filter structure can avoid traditional drain filter need first blind off a line when the inner impurity of discharge line, again filter valve gap is opened the trouble of clearing up impurity, effectively can improve the operational efficiency of pipeline medium, can reduce again the cost of labor of dismounting filter blowdown, but also the selection adding blowdown end connection device is installed or unloads, and adds the security that equipment runs.But it cannot detect pressure differential before and after filter, can not according to operating mode automatic pollution discharge; Need manually to carry out judgement and fulfil blocking Chengdu and manual operation.
Summary of the invention
The utility model is the deficiency in order to overcome existing for above-mentioned prior art, provide a kind of automatic dirt-removing filtering device, after its filter net jam and after front and back pressure reduction is increased to certain critical value, can automatic pollution discharge, and automatic pollution discharge after-filter automatically restores to normal operating conditions.
A kind of automatic dirt-removing filtering device, it comprises housing, turnover panel, pivot, control chamber, communicating pipe, filter screen and blow-off pipe, filter net device is in housing, turnover panel also can rotate freely by being pivotally hinged in control chamber, communicating pipe connects blowoff valve outlet side and control chamber, control chamber and filter screen, blow-off pipe, communicating pipe is interconnected, described turnover panel closes filter screen outlet and blow-off pipe under gravity, after the impurity in filter screen too much causes pressure reduction before and after filter to increase and reaches certain critical value, turnover panel rotates up and closes communicating pipe under the effect of pressure differential, now fluid carry-over impurity flow into blow-off pipe by its interior.
Above-mentioned filter axis is 0-90 ° of layout.
The utility model has following beneficial effect:
The utility model carries out automatic pollution discharge mechanically, decrease manually remove contamination or install magnetic valve required cost; By carrying out action to the judgement of pressure reduction before and after filter, decrease the fluid drainage that timing blowdown causes.Unmanned, does not need power supply or control circuit, reliable, and overall structure is simply compact; The parts such as housing, filter screen, turnover panel belong to the type widely of Application comparison, and development cost is low, is convenient to large-scale production and use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is that the facade of prior art one arranges schematic diagram.
Fig. 2 is that the facade of prior art two arranges schematic diagram.
Fig. 3 is that facade of the present utility model arranges schematic diagram.
Detailed description of the invention
As shown in Figure 3, the device that the utility model relates to is primarily of the composition such as housing 1, turnover panel 2, pivot 3, control chamber 4, communicating pipe 5, filter screen 6, blow-off pipe 7, the connected mode of each parts is: filter net device is in housing 1, turnover panel 2 is hinged in control chamber 4 by pivot 3 and also can rotates freely, connect blowoff valve outlet side and control chamber 4 communicating pipe 5, control chamber 4 with are interconnected filter screen 6, blow-off pipe 7, communicating pipe 5, filter axis is 0-90 ° of layout.Rotatable panel turnover device can be replaced by the structure of other shapes; The connectivity capabilities of communicating pipe can be realized by the runner of enclosure interior.
The utility model realizes the motion of action triggers by pressure differential before and after turning device and filter.Specific works principle is as follows:
During normal work, turnover panel closes filter screen outlet, blow-off pipe under gravity, and now fluid flows through filter by filter screen, and impurity deposits or adheres in filter screen.
After the impurity in filter screen too much causes pressure reduction before and after filter to increase and reaches certain critical value, turnover panel rotates up and closes communicating pipe under the effect of pressure differential, and now fluid carry-over impurity flow into blow-off pipe by its interior, thus realizes dirt eliminating function.
When blowdown process lasts to a certain extent time, after before and after filter, pressure reduction is decreased to certain critical value, turnover panel be rotated down under gravity and close filter screen outlet and blow-off pipe, blowdown process terminates, and filter returns to normal operating conditions.
