The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 3, the invention is applied to all existing sedimentation tanks, and is correspondingly improved on the basis of the existing equipment, the original clear water channel is the water collecting tank 1 of the invention, and the improved water collecting tank 1 can be opened or sealed. Offer a plurality of holes on water catch bowl 1 bottom plate for installation is transferred to tee bend 2, and the even interval arrangement of transfer to tee bend 2 sets up, and every transfer to the filtration water inlet A of tee bend 2 corresponds a rose box 3, through supporting 4 spaced installations in water catch bowl 1 bottom plate below, rose box 3 adopts independent setting, no longer receives the influence of involving each other, and rose box 3 effect is carried out the filtration once more to the water after the reaction precipitation, further improves the water purification standard.
The working principle of the invention is as follows: after the sewage in the reaction sedimentation tank is precipitated, the precipitated impurities can fall to the lower part of the reaction sedimentation tank, the water at the upper part of the reaction sedimentation tank is clean, but the water at the moment can not reach the industrial water discharge standard, the clean water is flushed to the plurality of filter tanks 3 under the action of the water potential flowing by the water flow at the moment, the filter tanks 3 are independently arranged for expanding the filter surface, the four peripheral surfaces and the bottom surface are all filter surfaces, the filter area is greatly increased, the filter effect is improved, and the purified water filtered by the filter tanks 3 further reaches the new purification standard. And then enters the main through pipe 21 from the filtered water inlet end A of the direction-regulating tee joint 2. At this time, because the back flushing is not started, simultaneously, under the pulling force of the turning guide plate tension spring 25, the turning guide plate 24 is in a natural falling state, the turning guide plate 24 is positioned through the lower limit opening 26, the main through pipe 21 is communicated to form a filtering pipeline, purified water enters the water collecting tank 1 along the filtering water outlet end B at the upper end of the main through pipe 21 which is vertically arranged, and is discharged from the outer discharge opening of the water collecting tank 1.
After a period of use, the outer surface of the filter tank 3 will be adhered with some impurities such as flocculate, thus causing blockage to the filter tank 3 and slowing down the filtering speed, so the invention sets the backwash pipe 22 and the backwash pipe, and periodically opens the backwash pipe by controlling the electromagnetic valve on the main supply pipe 6. When back flushing is started, the purified water in the water collecting tank 1 is used as a purified water source, water is supplied through the main supply pipe 6, high-pressure water is distributed to the plurality of branch pipes 7, each branch pipe 7 is communicated with a back flushing pipe 22 of the direction-regulating tee joint 2, and the pressure of the high-pressure water is larger than the water pressure generated by the flow of the purified water in the main through pipe 21, so that the overturning guide plate 24 is forced to overturn into the main through pipe 21.
The positioning of the flip guide 24 of the present invention can take two forms, embodiment one:
as shown in fig. 4, when the turnover guide plate 24 is positioned at 45 ° -89 °, the turnover guide plate 24 is elliptical, the upper limit opening 27 is in the shape of an oblique cut, the upper limit opening 27 is provided with a cut at the inner wall of the pipe body of the main pipe 21, the oblique cut angle is consistent with the positioning angle of the turnover guide plate, and the turnover guide plate is abutted against the edge of the upper limit opening, so that the sealing is more compact, thereby blocking the road of the main pipe 21. The effect of slope setting is protection upset deflector extension spring 25, reduces the pulling of upset deflector extension spring 25 for the life of upset deflector extension spring 25 is longer. The back flushing water enters through the back flushing pipe 22 and then is impacted to the filter tank 3 through the pipe body filter water inlet end A at the lower part of the main through pipe 21, and the high-pressure back flushing water flushes the filter tank 3 from inside to outside, so that impurities such as flocculating substances adhered to the outer surface of the filter tank 3 are flushed, the purposes of scrubbing and cleaning are achieved, manual cleaning is not needed, and time and labor are saved.
Example two
As shown in fig. 5, when the turnover guide plate 24 is positioned at 90 °, the turnover guide plate 24 is circular, the upper limit opening 27 is in a shape of a right cut, and is arranged at the filtered water outlet end of the main pipe, and the turnover guide plate abuts against the lower edge of the tangent opening, so that the sealing is more compact, and the road of the main pipe 21 is blocked. Because the main through pipe 21 and the recoil pipe 22 adopt the same-specification pipelines, the inner diameters are the same, the design is convenient for production, and only the overturning guide plate 24 is cut into round pieces slightly larger than the inner diameters of the main through pipe 21 and the recoil pipe 22, thereby being easy for production and popularization. The back flushing water enters through the back flushing pipe 22 and then is impacted to the filter tank 3 through the pipe body filter water inlet end A at the lower part of the main through pipe 21, and the high-pressure back flushing water flushes the filter tank 3 from inside to outside, so that impurities such as flocculating substances adhered to the outer surface of the filter tank 3 are flushed, the purposes of scrubbing and cleaning are achieved, manual cleaning is not needed, and time and labor are saved.
When the electromagnetic valve on the back flush pipeline is closed, back flush is closed, and under the action of the tension force of the turnover guide plate tension spring 25, the turnover guide plate 24 rapidly returns to the original state, so that the main through pipe 21 is conducted again, and the purification treatment is continued. And the operation is repeated, so that the manual workload is reduced, and the water purification efficiency is improved.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced with equivalents; such modifications and substitutions do not depart from the spirit of the technical solutions according to the embodiments of the present invention.
