Description
Technical field
It the utility model is related to mechanical manufacturing field, and in particular to a kind of seawater filtering device that can be cleared up automatically.
Background technology
The special seawater filter of ship is one of equipment more typical in shipping industry, and conventional seawater filter includes outer
Shell, stainless (steel) wire, blowdown etc., stainless steel filtering net is wound into tubular and is built in as cartridge filter in shell, and the side wall of shell is set
There are water inlet pipe and outlet pipe, water inlet pipe is stretched into shell and connected with filtering tube inner chamber, and outlet pipe connects with shell inner cavity.
At work, seawater to be filtered is entered in cartridge filter filter by water inlet pipe, the clean sea under differential pressure action
The annular chamber that water enters shell and screen pack through cartridge filter, then exclude to realize by outlet pipe and filter, the particle in seawater
Impurity is trapped within inside screen pack.
But said structure has the following disadvantages：With continuing for filtering, the continuous adsorbing contaminant of meeting, is caused on cartridge filter
The filter efficiency of cartridge filter reduces, or even blocks, it is therefore desirable to frequently carries out back flush, blowdown, just can ensure that filter
Continue normal work, greatly reduce filter efficiency.
In view of secondary, the inventor of this case is proposed a kind of seawater filtering device that can be cleared up automatically, allow screen pack through
It is durable long, and there is good filter effect.
Utility model content
To solve problem above, the utility model is achieved through the following technical solutions：
A kind of seawater filtering device that can be cleared up automatically, including filter cylinder, water inlet and delivery port；Before definition water inlet is
Side, delivery port is rear, it is characterised in that the filter cylinder internal frame is provided with the first filter screen, if bar of the filter screen from dry doubling to arrangement
Block is formed, and the second filter screen is provided with the filter cylinder, if second filter screen is made up of dry doubling to the annulus of arrangement, each stick
Intersected Heterogeneous Permutation with each annulus, be provided with rotating shaft among second filter screen, each annulus by connecting rod and
The rotating shaft is connected, and the rotating shaft is connected with the rotary electric machine by preceding rotating down, and collecting sewage room is provided with below second filter screen.
Further, some blades being vertically arranged are fixed with filter cylinder and are placed in lower section on rear side of second filter screen, respectively
The blade and each annulus intersect Heterogeneous Permutation, and the blade of each blade is towards second filter screen.
Preferably, collecting sewage room is equipped with sewage draining exit.
Further, it is identical with each annulus radian formed with arc convex, the raised radian forward in the middle part of stick.
Beneficial effect：
1st, the relative motion between the first static filter screen and the second filter screen of motion, will can be stuck among screen pack
Rubbish is stripped out, and setting motor to move downward can make the rubbish of stripping move downward and enter collecting sewage room；
The 2nd, blade is set below the rear side of the second filter screen, blade can prevent contingency second from filtering equivalent to block herein
There is sea grass etc. to be difficult to the thing peeled off on the net, can be cut herein by blade, and blade be arranged on rear can be by rubbish
Rubbish is blocked in outside delivery port, drops to blowdown room downwards；
3rd, the cleaning to rubbish can be facilitated in collecting sewage room's arranging sewage draining exit；
4th, the gap that arc convex is set in the middle part of stick can make the first filter screen and the second filter screen cooperate reduces, so as to
Make filter effect more preferably.
Brief description of the drawings

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, it will be appreciated that this practicality is new
The structure of type is not limited in following examples：
Embodiment 1：As illustrated, the seawater filtering device, including filter cylinder 1, water inlet 11 and delivery port 12；Definition water inlet
Mouth 11 is front, and delivery port 12 is rear, it is characterised in that the internal frame of filter cylinder 1 is provided with the first filter screen 2, and the filter screen is by some
And formed to the stick 21 of arrangement, the second filter screen 3 is provided with the filter cylinder 1, if circle of second filter screen 3 from dry doubling to arrangement
Ring 31 is formed, and each stick 21 and each annulus 31 are intersected Heterogeneous Permutation, and rotating shaft is provided among second filter screen 3
32, each annulus 31 is connected by connecting rod 33 with the rotating shaft 32, and the rotating shaft 32 is connected with to be turned by what is preceding rotated down
Dynamic motor 34, the lower section of the second filter screen 3 are provided with collecting sewage room 4.
Rubbish enters from water inlet 11, is obstructed by being cooperated between the first filter screen 2 and the second filter screen 3, is just isolated in
Outside screen pack, when there is stopping state, the second filter screen 3 of rotation can separate the rubbish being blocked in gap, lead to
The second filter screen of driving 3 of motor is crossed by preceding moving downward, rubbish can down be transported in the past, enable rubbish in collecting sewage room 4
Middle concentration.
