Description

Environment-friendly sewage filtering system and filtering method

Technical Field

The invention relates to the technical field of sewage filtration, in particular to an environment-friendly sewage filtration system and a filtration method.

Background

The sewage treatment is mainly to make sewage reach the water quality requirement of draining into a certain water body or reusing and purify it, in the sewage treatment process, firstly, it is necessary to carry out physical mechanical treatment on sewage, namely, first stage treatment in the sewage treatment system, in the first stage treatment, it is necessary to pretreat sewage by utilizing filter elements such as filter screen, filter plate or filter disc, etc., and filter out larger particles and suspended matters in the sewage, so as to facilitate the treatment of the next stage.

For example, patent literature with an authorized bulletin number of CN218011436U provides a sewage filtering device, which solves the problems that in the prior art, in the use process of the sewage filtering device of physical system in the market, a screen is used for a long time, and some aquatic organisms or sundries inevitably remain on the surface of the screen, so that after the device is used for a period of time, people need to clean the screen in the device, and the cleaning process is time-consuming and laborious, places where people cannot contact are easy to exist, dead angles are left for cleaning, and the workload of the people is increased. A sewage filtering device comprises a shell, wherein one side of the upper surface of the shell is rotationally connected with a cover plate. According to the utility model, the traditional mode is changed, the hand-held device of the personnel cleans sundries adsorbed on the screen, the problem of dead angles which cannot be cleaned is avoided, the screen is ensured to be cleaned neatly, the workload of the personnel is reduced, and the actual use efficiency of the device is improved.

However, when the utility model is specifically used, the parts such as the vertical plate, the brush plate and the bidirectional screw rod are all arranged in the shell, so that on one hand, impurities on the screen can only be cleaned into the shell, and then the impurities in the shell are manually taken out, so that some extra burden is brought to workers, on the other hand, when the brushes are used for cleaning, the moving brushes are difficult to insert into the meshes, and basically only the surfaces of the screen are moved for cleaning, so that the blocking objects in the meshes cannot be cleaned at all, and moreover, the parts are arranged in the shell to seriously influence the sewage flow, so that the sewage treatment efficiency is reduced, and the speed of the whole sewage treatment link is not improved.

Therefore, it is necessary to provide a new environment-friendly sewage filtering system and filtering method to solve the above technical problems.

In this embodiment:

the water inlet pipe and the water outlet pipe on the filter tank 5 are respectively communicated with the previous stage and the next stage of treatment process through external pipelines, and in the initial state, the output shafts of the two telescopic cylinders II 32 are in an extending state;

when sewage is filtered, the sewage is firstly discharged into the filter tank 5 through the water inlet pipe, after being discharged, the sewage firstly passes through the first-stage filter plate 7 and then passes through the second-stage filter plate 8, and finally is discharged into the next process through the water outlet pipe, and in the sewage circulation process, the first-stage filter plate 7 and the second-stage filter plate 8 perform double filtration on the sewage, so that larger particle impurities in the sewage can be intercepted;

After the sewage treatment is finished, at this moment, more particle impurities are attached to the filter tank 5 and the first-stage filter plate 7 and the second-stage filter plate 8, at this moment, the output shafts of the two telescopic air cylinders II 32 are started to retract firstly, the two blocking plates 25 are lowered under the drive of the connecting rod 27 until the two blocking plates 25 are lowered to the final height, the top plane of the blocking plates 25 at this moment is flush with the bottom end face of the sealing plate 6, then, the two motors II are started forward, the output shafts of the two motors II drive the corresponding one-way screw rods II 30 to rotate, so that the two telescopic air cylinders II 32 can horizontally move with the connecting rod 27 and the two blocking plates 25 under the threaded cooperation of the one-way screw rods II 30 and the linkage plate II 31, in the moving process, the accumulated objects on the two blocking plates 25 can be scraped until the two blocking plates 25 are completely staggered with the corresponding drain openings 24 respectively, at this moment, the particle impurities accumulated in the filter tank 5 can directly fall down and fall on the drain vehicles below;

then, in order to ensure the filtering performance of the first-stage filtering plate 7 and the second-stage filtering plate 8, two rodless cylinders 9 can be started, the sliding blocks on the two rodless cylinders 9 are lowered along with the frame body 10, in the lowering process, the first bearing plate 13, the second bearing plate 14 and the first box body 20 are lowered into the filtering pond 5 until the first bearing plate is lowered to the final position, the first-stage dredging rods 15 correspond to the filtering holes on the first-stage filtering plate 7, the second-stage dredging rods 16 correspond to the filtering holes on the second-stage filtering plate 8, then, the output shafts of the first telescopic cylinders 17 are started to extend, the first bearing plate 13 and the second bearing plate 14 move simultaneously in the same direction under the connection of the transverse pull rods 11 and the vertical connecting rods 12, finally, a plurality of first-stage dredging rods 15 and a plurality of second-stage dredging rods 16 are inserted into the corresponding filtering holes, and after the plugs in the filtering holes are pushed out, in the pushed out state, the ends of the first-stage dredging rods 15 are close to one face of the first-stage filtering plate 7 and the second-stage filtering plate 7 are not flush with one face of the second-stage filtering plate 8, and the second-stage dredging rods 16 are flush with the corresponding filtering plate 8;
