the filter element 14 is formed by laminating a plurality of filter layers with different elasticity, a plurality of hollow pipes which are uniformly distributed in the gravity direction and the circumferential direction are arranged on the outer circumferential surface of the filter element 14, one end of each hollow pipe is vertically and fixedly inserted in the filter element 14, the other end of each hollow pipe is a U-shaped transitional sealing opening, a fine hole is formed in the middle of each sealing opening, namely, the fine hole is formed in the position flush with the axis of each hollow pipe, and a plurality of bulges which are spaced side by side are arranged on the inner wall of the pipe body of each hollow pipe.
Furthermore, the hollow tube is made of plastic.
In the first embodiment, make sewage fully contact through the filter core 14 that turns up, adopt the physics filtration method, make the solid particle who carries in the sewage detain in filter core 14, reach the purpose of purifying sewage, the water after the purification discharges away through water purification discharge pipe 9, but the filter core itself can reach the absorption saturation very fast, its time of endurance is shorter, utilize centrifugal method to carry out temporary separation storage to the hollow tube with particulate matter or silt in the filter core 14 in this embodiment, thereby promote filter core filtration performance by a wide margin, and subsequent washing convenience, concrete working process and principle are as follows:
the rotating filter element 14 is fully contacted with sewage, a physical filtering method is adopted, solid particles carried in the sewage are retained in the filter element 14, the particles retained in the filter element 14 slowly form a sludge colloid shape, because a plurality of filter layers with different elasticity are laminated in the filter element 14, in the process of high-speed rotation of the filter element 14, the filter element 14 is extruded and deformed under the action of centrifugal force, and the elasticity of the material of each filter layer on the filter element 14 is different, the filter layers are mutually extruded, so that the absorbed sludge overflows to the surface from each filter layer of the filter element, the sludge and water overflowing to the surface are thrown into the hollow tube by virtue of the inserted hollow tube, the sludge in the hollow tube is blocked by a plurality of bulges arranged at intervals, the moving speed of the sludge is lower than that of the water, and the thrown water penetrates out of the pores of the U-shaped sealing opening at the front end of the hollow tube body, the sludge is effectively blocked in the hollow pipe bodies, so that the sludge is stored in the hollow pipe bodies, and the cruising ability of the filter element 14 is greatly improved;
in addition, the motor which drives the filter element 14 to rotate works in two working modes of acceleration and smooth rotation in turn, and the duration of the acceleration rotation period is shorter than that of the smooth rotation period, for example, in the rotation process of the motor, after 5 minutes of smooth rotation, a variable acceleration period of 30 seconds is carried out, then 5 minutes of smooth rotation is carried out, and then 30 seconds of variable acceleration period is carried out, so that the cycle is repeated. The operation mode of the motor is such that after the filter element 14 has been rotated for a certain period of time to absorb the particles, a centrifugal throwing process is performed, so that the sludge in the filter element 14 is periodically stored in the hollow tube. Although a small amount of sludge can enter the hollow pipe by the centrifugal force generated in the stable rotation process of the motor, the sludge thrown away by the centrifugal force generated in the acceleration period is far less than the sludge thrown away by the centrifugal force generated in the variation period and has strong capability of crossing the raised obstacles in the hollow pipe body, because the centrifugal force generated in the variation period can promote the sludge to creep outwards while intensifying the extrusion deformation among the filter layers in the filter element 14, and the sludge can more easily pass through the raised obstacles in the pipe wall of the hollow pipe.
In addition, the surface and the inside of the first trapezoidal inner bottom 16 and the second trapezoidal inner bottom 17 are respectively provided with fine pores and filter element cotton materials, the first trapezoidal inner bottom 16 and the second trapezoidal inner bottom 17 adopt a detachable design in the sewage filtering barrel 1, and when the two trapezoidal inner bottoms form a sewage discharge outlet, the dual functions of filtering are also exerted, so that the filtering effect is better. The detachable design makes the cleaning of the filter element surface and the fine pores simple.
Finally, when the sludge in the hollow pipe body is close to the full capacity, the cleaning work of the filter element is needed to be carried out: close the motor, filter core 14 stops rotatoryly, stop to pour into sewage, close blow off pipe 9 and sewage import pipe 3, and open the drain of bottom and discharge totally the back, open the motor once more and work at high-speed rotatory mode, pour into clean washing water to filter core 4 in through just wash water pipe 7, this clean water carries out the direct washing with remaining silt and granule in each filtering layer of filter core simultaneously, the interior silt of hollow tube pipe is gone on still continuously to impact to clean water, and take out silt from the pore of front end U-shaped seal, the process of pouring into must be dry water, thereby the speed of silt cleaning is far greater than the speed that silt stopped at the body inner wall, thereby guarantee can not have silt to be detained in the hollow tube body again, accomplish just washing work.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
