Example 2
Referring to fig. 6 to 8, the present embodiment further includes the following features on the basis of embodiment 1: the water inlet is connected with a water suction pump, the water inlet end of the water suction pump is connected with a filtering assembly through a hose, and the filtering assembly floats on the sea surface; the filtering component comprises a floater 91, a connecting cover 92 fixedly connected to the lower end of the floater, a ceramic filter element 93 which is connected to the lower end of the connecting cover and is integrally cylindrical, and a brush body 94 which is sleeved on the periphery of the ceramic filter element and used for brushing the blockage on the outer wall of the ceramic filter element in the vertical movement process.
The side fixedly connected with of connecting the lid goes out water and takes over 921, the lateral wall shaping that goes out the water and takes over has coupling a922, go out the inside intercommunication of water takeover and ceramic filter core.
The upper end of the ceramic filter element is fixedly connected with an annular filter element upper joint 931 made of plastic, and the filter element upper joint is connected with the lower end of the connecting cover through threads; the lower end of the ceramic filter element is fixedly connected with a filter element lower connector 932 made of plastic material for sealing the lower end of the ceramic filter element; the diameter of filter core lower clutch is greater than the diameter of ceramic filter core, a plurality of vertical guide bar 933 that set up of periphery fixedly connected with that the filter core lower clutch upper end is located ceramic filter core, and each guide bar is arranged along ceramic filter core circumference equidistance.
The brush body comprises a brush base 941 which is annular as a whole and has an opening at the lower end, an annular brush cover 942 which is connected to the lower end of the brush base in a sealing way, an annular piston 943 which is arranged in the brush base in a sealing and sliding way, and a spring 944 which is arranged between the upper end of the piston and the top in the brush base; the inner periphery of the brush base is uniformly connected with brush bristles 9412 for brushing off plugs on the outer wall of the ceramic filter element; a pipe joint b9411 is formed on the side surface, close to the upper end, of the brush seat, and the pipe joint b is connected with the pipe joint a through a hose; the space between the piston and the brush cover in the brush body is filled with gas easy to liquefy; the readily liquefiable gas may be freon.
The outer diameter of the brush cover is larger than that of the brush base, and guide holes 9421 which are in sliding connection with the guide rods respectively are formed in the brush cover.
The buoyancy value of the float in water is 1.2 times larger than the whole weight of the filtering component.
When the negative pressure value in the ceramic filter element is increased to be larger than the elastic force of the spring, negative pressure is formed above the piston in the brush seat communicated with the interior of the ceramic filter element through the hose, the water outlet connecting pipe and the connecting cover in sequence, so that the piston compresses the spring to move upwards.
When the piston moves to the top limit position in the brush body under the action of negative pressure, the buoyancy of the brush body is larger than the self gravity of the brush body, so that the brush body moves from bottom to top along the guide rod; when the piston moves to the limit position of the bottom in the brush body, the gravity of the brush body and water in the brush body is larger than the buoyancy of the brush body, so that the brush body moves from top to bottom along the guide rod.
A pipeline connected with the water inlet end of the water suction pump is connected with a fluid pressure sensor, when the fluid pressure sensor detects that the negative pressure value (absolute value) is larger than a set value, the outer wall of the ceramic filter element is judged to be blocked, and at the moment, the output power of the water suction pump is controlled to be alternately increased and decreased for a period of time (2-5 min); when the output power of the water suction pump is increased, negative pressure is formed in the brush body communicated with the water inlet end of the water suction pump, and when the piston moves to the top limit position in the brush body under the action of the negative pressure, the buoyancy of the brush body is larger than the gravity of the brush body, so that the brush body moves from bottom to top along the guide rod, and the bristles brush the outer wall of the ceramic filter element; when the output power of the water suction pump is reduced, the negative pressure in the brush body communicated with the water inlet end of the water suction pump is reduced, the piston moves to the limit position of the bottom in the brush body under the action of the restoring force of the spring, the brush body and the gravity of water in the brush body are larger than the buoyancy of the brush body, the brush body moves from top to bottom along the guide rod, and therefore the bristles are used for brushing the outer wall of the ceramic filter element again. After a plurality of times of brushing, the ceramic filter element is recovered to a normal filtering state.
Through the structure, the brush body is not required to be driven to move by designing redundant driving parts, and the function of automatically cleaning the ceramic filter element is realized only by the water suction pump carried by the system.
Compared with the chinese patent document CN105688478A, although it also achieves the function of automatically brushing the ceramic filter, it is only suitable for the structure in which the ceramic filter is enclosed in a closed housing, and is not suitable for the case where the ceramic filter needs to be in an open environment as in the present invention. Furthermore, the brush body moves up and down to realize the brushing action by changing the difference value between the overall weight and the buoyancy of the brush body, the design is ingenious, the water entering and exiting the brush body is filtered, the piston cannot be hindered by impurities in the moving process, and the service life and the maintenance-free time are obviously prolonged.
