As a specific embodiment of the invention, the scraping block 7 comprises two scraping blocks 18 and a nylon brush 19, the two scraping blocks 18 are symmetrically and fixedly installed at two ends of the nylon brush 19, the nylon brush 19 is used for cleaning the surface of the grating 3, during operation, the two scraping blocks 18 are arranged, so that the scraping blocks 18 can scrape off sludge on the surface of the grating 3 when the scraping block 7 moves back and forth, meanwhile, the working surface of the scraping block 18 is provided with a pointed end, when the scraping block 18 moves, the pointed end part of the scraping block 18 plays a role similar to a shovel, so that the sludge is easily taken up by the scraping block 18, and the scraping effect of the scraping block 18 on the sludge is enhanced; through the setting of nylon brush 19 to make the bottom surface height of nylon brush 19 be less than the bottom surface height of scraping piece 18, when the bottom surface of scraping piece 18 and the surface contact of grid 3, nylon brush 19 and the surperficial in-process of grid 3 for nylon brush 19 is at the in-process through the grid 3 surface, and nylon brush 19 cleans the silt on grid 3 surface totally, has improved the mud efficiency of scraping piece 7, thereby has guaranteed the filter effect of grid 3.
As a specific embodiment of the invention, the bottom of the sedimentation tank 1 is arranged in an inclined manner, the included angle between the bottom of the sedimentation tank 1 and the horizontal plane is 15-20 degrees, and when the sedimentation tank works, because suspended matters in sewage have gravity, the bottom of the sedimentation tank 1 is arranged in an inclined manner, so that the sewage is settled at the bottom of the sedimentation tank 1 by overcoming the gravity of the sewage in the moving process, and the purification effect of the sedimentation tank 1 is improved.
When the sedimentation tank works, the sedimentation tank is a structure for removing suspended matters in water by applying sedimentation, is widely used in wastewater treatment, has a plurality of types, and can be divided into a horizontal flow type, a vertical flow type and a radial flow type according to the water flow direction in the tank; the sedimentation tank is generally a structure for separating mud and water before or after biochemistry, and most of the sedimentation tank is sludge with finer separation particles; the sedimentation tank before biochemistry is called a primary sedimentation tank, and the sedimentation tank after biochemistry is generally called a secondary sedimentation tank; for a small sewage treatment plant, the sedimentation tank occupies a small area, and when the horizontal flow sedimentation tank is adopted to purify sewage, the retention time of the sewage in the sedimentation tank is short, and fine suspended particles are easy to be carried out when the sewage is discharged, which is caused by the fact that suspended matters are not settled, through the baffle plates 2 which are arranged in a staggered mode, because the two ends of each baffle plate are fixedly connected with the side wall of the sedimentation tank 1, the sewage added with a flocculating agent is enabled to zigzag and advance when passing through the sedimentation tank 1, the moving distance of the sewage in the sedimentation tank 1 is prolonged, the retention time of the sewage in the sedimentation tank 1 is directly prolonged, meanwhile, the sewage is changed into a moving mode from top to bottom and from bottom to top, the suspended matters in the sewage are settled due to the self gravity, the suspended matters in the sewage are fully settled, and the sewage treatment effect is improved; the grids 3 are arranged in a crossed manner, so that suspended matters in the sewage are partially intercepted by the grids 3 when the sewage passes through, the quantity of the suspended matters moving in the sewage is reduced, and the purity of the sewage is improved; in the process that the sewage is changed from top to bottom to move upwards, suspended matters in the sewage are settled in the sludge storage hopper under the action of gravity, when the sludge in the sludge storage hopper reaches a certain amount, the controller controls the sludge pump to work, the sludge pump sucks the sludge in the sludge storage hopper into the sludge discharge pipe 8 and discharges the sludge out of the sedimentation tank 1, the continuous purification effect of the sedimentation tank 1 is ensured, after filtering and intercepting sewage for a long time, the surface of the grating 3 is covered by sludge, the sludge weakens the filtering action of the grating 3, the controller starts the control motor 4 to work at regular time, the motor 4 drives the screw rod 5 to rotate, so that the screw 5 drives the pressing plate 6 which is in threaded connection with the screw to move, thereby leading the scraping blocks 7 on the side wall of the pressing plate 6 to be in contact with the surface of the grating 3, the sludge on the surface of the grating 3 is scraped in the process that the scraping block 7 moves, so that the grating 3 keeps a stable working state, and the purification efficiency of the sewage is improved.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
