The metal structure of water filter metallic object, the metal structure are set between the water inlet and the water outlet, this kind of seawater filter
Device has the following problems when in use, can not be intuitive since the metal structure as sacrificial anode is in sea water filter metallic object
Observing corrosion condition, it is therefore desirable to regular check is corroded situation, larger workload, if replacing metal structure not in time,
Seawater can cause to corrode to sea water filter metallic object, influence using for this purpose, it is proposed that a kind of sea peculiar to vessel of cathodic protection
Water filter.
Utility model content
The purpose of this utility model is to provide a kind of sea water filters peculiar to vessel of cathodic protection, to solve above-mentioned background
Itd is proposed in technology since the metal structure as sacrificial anode is in sea water filter metallic object, can not intuitively observe corrosion feelings
Condition, it is therefore desirable to which regular check is corroded situation, and larger workload, if replacing metal structure not in time, seawater can be to seawater
Filter metallic object causes to corrode, influence using the problem of.
To achieve the above object, the utility model provides the following technical solutions: a kind of seawater peculiar to vessel of cathodic protection
Filter, including tube body, the tube body right hand top are provided with outlet pipe, and flowmeter, the water outlet are equipped on the outlet pipe
Pipe right end is welded with first flange disk, and the tube body left bottom is provided with water inlet pipe, and the water inlet pipe left end is welded with second
Ring flange, the tube body top are welded with third ring flange, are provided with end cap, the end cap edge at the top of the third ring flange
Bolt is bolted between position and third ring flange, the end cap bottom is bolted with the filter cylinder to match with tube body, the filter cylinder
It is plugged on the inner cavity of tube body, filter cylinder left side wall bottom offers the water inlet to match with water inlet pipe, the filter cylinder inner cavity
It uniformly is vertically arranged with sacrificial anode plate, the sacrificial anode plate is staggered, and is screwed onto end cap at the top of the sacrificial anode plate
Bottom.
Preferably, the tube body, outlet pipe and water inlet pipe one cast molding.
Preferably, the sacrificial anode plate is magnesium alloy plate or kirsite plate.
Preferably, ceramic seal circle is provided between the end cap and third ring flange.
Compared with prior art, the utility model has the beneficial effects that the New Scheme is by being mounted on outlet pipe
Flowmeter is monitored the water flow of outlet pipe, after the sacrificial anode plate in filter cylinder is corroded completely by seawater, manages intracorporal
Resistance becomes smaller, and since pipe diameter is constant, water flow can become larger, and staff replaces sacrificial anode plate at this time, mitigation work significantly
The labor intensity of personnel, it is convenient and efficient, effectively avoid seawater corrosion, influence using the case where occur.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model end cover structure schematic diagram；
Fig. 3 is the utility model sacrificial anode plate structural schematic diagram.
In figure: 1 tube body, 2 flowmeters, 3 outlet pipes, 4 first flange disks, 5 end caps, 6 bolts, 7 third ring flanges, 8 water inlets
Pipe, 9 second flange disks, 10 filter cylinders, 11 sacrificial anode plates, 12 water inlets.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of seawater peculiar to vessel filter of cathodic protection
Device, including tube body 1,1 right hand top of tube body are provided with outlet pipe 3, are equipped with flowmeter 2 on the outlet pipe 3, it is described go out
3 right end of water pipe is welded with first flange disk 4, and 1 left bottom of tube body is provided with water inlet pipe 8,8 left end of the water inlet pipe welding
There is second flange disk 9, third ring flange 7 be welded at the top of the tube body 1, is provided with end cap 5 at the top of the third ring flange 7,
Bolt 6 is bolted between 5 marginal position of end cap and third ring flange 7,5 bottom of end cap is bolted with and 1 phase of tube body
The filter cylinder 10 matched, the filter cylinder 10 are plugged on the inner cavity of tube body 1, and the 10 left side wall bottom of filter cylinder offers and 8 phase of water inlet pipe
Matched water inlet 12,10 inner cavity of filter cylinder are uniformly vertically arranged with sacrificial anode plate 11, and the sacrificial anode plate 11 interlocks
It is arranged, the bottom of end cap 5 is screwed at the top of the sacrificial anode plate 11.
Wherein, the tube body 1, outlet pipe 3 and the integrated cast molding of water inlet pipe 8, stable structure, the sacrificial anode plate 11
For magnesium alloy plate or kirsite plate, it is provided with ceramic seal circle between the end cap 5 and third ring flange 7, guarantees leakproofness.
Working principle: when in use, seawater is entered in filter cylinder 10 New Scheme by water inlet pipe 8 and water inlet 12,
Impurity in seawater is stayed in filter cylinder by filter opening obstruction on filter cylinder 12, and filtered seawater is pushed up on the right side of tube body 1 by setting
The outlet pipe 3 in portion is gone out, and 11 activity of sacrificial anode plate due to being screwed onto 5 bottom of end cap is higher than tube body 1, and seawater can first corrode
Sacrificial anode plate 11, without corroding tube body 1, when the sacrificial anode plate 11 for being staggeredly screwed onto 5 bottom of end cap is completely rotten by seawater
After erosion, the resistance in tube body 1 becomes smaller, and water flow throughput becomes larger naturally, is mounted on 3 flow meter 2 of outlet pipe at this time and monitors out
Water flow in water pipe 3 becomes larger, and staff is reminded to replace sacrificial anode plate 11, and staff backs out bolt 6, by end cap 5 with
Third ring flange 7 separates, while filter cylinder 10 is pulled out tube body 1, removes filter cylinder 10 and sacrificial anode plate 11, after completing replacement,
It is by filter cylinder 10 again inlet pipe body 1, water inlet 12 is corresponding with water inlet pipe 8, bolt is installed, replacement is completed.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
