Description
Technical field
The utility model relates to a kind of water filter, especially a kind of sea water filter with automatic cleaning function.
Background technology
The harbour reconnaissance generally is selected in inland river and coastal region, and the craft tug of adequate and systematic service mainly is engaged in the towage of ship operation in these zones, partly navigates by water that the waters exists that the depth of water is shallow, water quality inferiority, characteristics that silt is many.For example: inland river, the mouth of the river etc., in order to maximally utilise the harbour water front, deepwater regions is all as the bull wheel berth, and the more shallow place of the depth of water often can only be selected in the mooring point of tugboat.When navigating by water in the phytal zone, because the stirring of screw can make the silt of precipitation dig, a large amount of silt is brought in the cooler of various device, thereby cause cooler to stop up or because washing away of silt makes heat-exchange tube transducer wall ' s abrasion in the cooler, reduce service life when serious (cooler use just damaged in 2 years) of cooler.By to the consulting of domestic 12 port tug companies, consult related data, tugboat water filter commonly used mostly is to adopt the straight-plate-type filter screen at present, filters before advancing cooler.Yet, in order to guarantee enough inflows, being subjected to the restriction of installation dimension, the mesh number of filter screen must reduce, and promptly the aperture of single mesh increases (Ф 5mm), and this just makes tiny silt to be filtered.Hence one can see that, if in the more waters operation of silt, water filter commonly used exists: shortcomings such as cleaning is frequent, and filter effect is bad.
The water filter that has automatic cleaning function in the market is electronic back flush type water filter, needs control of additionaling power source and complex structure, and the cost height does not meet the requirement of the synergy of joint money, energy-saving and emission-reduction.
Summary of the invention
The utility model is that a kind of eddy current self-cleaning type water filter will be provided, this water filter is simple in structure, automatically cleaning and good filtration effect, do not need the novel sea water filter in additionaling power source to reduce marine engineering management personnel's work load, can improve the equipment rate of attendance, assurance equipment normally moves.
The technical solution of the utility model is: a kind of eddy current self-cleaning type water filter, comprise filter body, filter screen, filter body top is provided with water inlet, and the bottom is provided with delivery port, and the bottom is provided with sewage draining exit, in the filter body, between water inlet and the delivery port filter screen is housed, and filter screen is conical, portlet connects sewage draining exit.
Delivery port is connected with cooler; Be connected with blowoff valve below the sewage draining exit, and the sewage draining exit of blowdown pressure regulator valve links to each other with the delivery port of cooler.
The water inlet area is 1: 20 with the area ratio of filter screen, and filter screen order number is the 32-100 order, and filtering accuracy is 100-1000 μ m; The blowdown bore is Ф 40mm.
The beneficial effects of the utility model are:
(1) do not need the extra power source to drive, the eddy current that utilizes filter water inlet itself to produce relies on eddy current to make silt assemble sinking automatically along cone to the centrifugal force that washes away and produce of filter screen conical surface.
This just reduces cost input and fault rate.
(2) adopt conical screen, filter area is big, thereby it is applied widely that the filtering accuracy adjustable extent is increased.
(3) pressure reduction that utilizes the water self in the cooling system to produce is discharged outboard to impurity.
(4) filtration is carried out simultaneously with blowdown, makes cooling water flow constant, and is uninterrupted.
(5) pass through the pressure loss of filter than little, because its filter area is big.
(6) simple in structure, there is not easily worn part, long service life and clean blowdown automatically.Realize non-maintaining, exempt from the management.
Therefore, the utility model is simple in structure, and maintaining is convenient, can block up by the fine solution tugboat easy stolen goods of sea water filter commonly used, and filter effect is bad, and the maintaining task heavily waits problem.

The specific embodiment
Below in conjunction with specific embodiment, further set forth embodiment of the present utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As Fig. 1, shown in 2, a kind of eddy current self-cleaning type water filter of the present utility model comprises filter body 1, filter screen 2, blowdown pressure regulator valve 6, cooler 7.
Filter body 1 top is provided with water inlet 3, and the bottom is provided with delivery port 4, and the bottom is provided with sewage draining exit 5, in the filter body 1, between water inlet 2 and the delivery port 3 filter screen 2 is housed, and filter screen 2 is conical, and portlet connects sewage draining exit 5.Delivery port 4 connects cooler 7; Connect blowdown pressure regulator valve 6 below the sewage draining exit 5, and the sewage draining exit of blowdown pressure regulator valve 6 links to each other with the delivery port of cooler 7.
As shown in Figure 3, operation principle of the present utility model:
The seawater that is mixed with impurity at first falls the impurity of larger particles through traditional filter filter 9, enter eddy current self-cleaning type water filter 10 by sea water pump 8 from off-centre then, utilize the flow velocity (2m/s is many) of sea water pump 10 water outlets this moment, current produce vortex and wash away wire side in the pyramid type filter core of filter screen 2, make silt and impurity under action of centrifugal force, rotate sinking, concentrate and enter into the sewage draining exit 5 of below.And a large amount of current are sent to cooler 7 by filter screen 2, because the throttling action of cooler 7 makes the water side of eddy current self-cleaning type water filter 10 produce back pressure, and the sewage draining exit 5 of eddy current self-cleaning type water filter 10 bottoms leads to outboard, this just makes two outlets in above and below of eddy current self-cleaning type water filter 10 produce pressure differential, forces a spot of water band the solid matter rotation and sinks down into the cone end opening through sewage draining exit 5 discharges.Because of two outlets produce pressure differential, make the water purification flow velocity less than effluent flow rate again, this just more helps the discharge of impurity.
Because cooling device operating mode difference is beneficial to adjust blowdown flow so installed blowdown control valve 6 additional at sewage draining exit 5.Reach and to satisfy the cooling device water, order ground that again can despumation.
This eddy current self-cleaning type water filter 10 is installed in the port of export of sea water pump 8, the current that enter filter have certain flow velocity, therefore filter water inlet area is 1/20 with the area ratio of filter screen, can reach optimum condition according to the filter screen of the water quality situation transposing different meshes in the different work waters at boats and ships place.
In addition, all greater than more than 50% of cooling institute water requirement, by data computation and analysis of experiments, this filter blowdown institute water loss is 1/15 (sewage/water purification=1/15) of water yield to pump capacity peculiar to vessel when Ship Design, therefore, the water yield that blowdown consumed does not influence the cooling water amount.
