Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a high-efficiency and energy-saving sewage degradation device. Background Art

[0002] Sewage refers to water produced after use or treatment, which usually contains various pollutants, including organic matter, inorganic matter, suspended matter and pathogens. Sewage treatment often requires a series of treatment processes and technologies to remove or reduce pollutants in sewage so that it meets discharge standards or can be safely reused. Sewage degradation is an important part of sewage treatment, which refers to the process of degrading organic pollutants in sewage into harmless substances through physical, chemical or biological methods. This process can reduce the pollution load of sewage, make it meet discharge standards or be further treated into recyclable water.

[0003] Sewage often contains organic pollutants that are difficult to degrade, such as clothing silk fibers, plastic pieces, and hair. In existing sewage treatment equipment, there is a lack of a structure to remove such filamentous and strip-shaped debris.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figure 1-8 , an efficient and energy-saving sewage degradation equipment, including a treatment pool 1, a perfusion cylinder 2 is arranged above the treatment pool 1, a rotating drum 3 is fixedly installed at the lower end outlet of the perfusion cylinder 2, and the lower end outlet of the rotating drum 3 is located in the treatment pool 1. The perfusion cylinder 2 is a truncated cone-shaped hollow cylinder with front and rear ends opened, the rear end large opening is the inlet, and the front end small opening is the outlet, and the horizontal height of the front end small opening is lower than the rear end large opening. The perfusion cylinder 2 with such a structural shape is arranged, and a large amount of water can be passed into the inlet of the perfusion cylinder 2, and is restrained by the front end small opening and discharged into the rotating drum 3, and the inclined setting can maintain sufficient potential energy of the sewage downward;

[0036] Furthermore, referring to Figure 5The inner center of the drum 3 is connected to a rotating shaft 31, and a plurality of paddles 32 are evenly fixed around the rotating shaft 31. A filter screen 33 is installed at the opening of the lower end of the front side of the drum 3, and a chip discharge port 34 is opened at the rear side of the drum 3. The sewage with sufficient potential energy enters the drum 3 and impacts the plurality of paddles 32 around the drum 3, so that the rotating shaft 31 in the drum 3 rotates, and the sewage flows to the lower front side of the drum 3, and after being sieved and removed by the filter screen 33, it flows into the treatment pool 1 below. Most of the particulate impurities can be removed from the sewage passing through the filter screen 33. The outer side of the paddle board 32 is close to the inner wall of the drum 3, and the outer side of the paddle board 32 is narrow and oblique. When the paddle board 32 is impacted and rotated through the filter screen 33, the paddle board 32 can clean the inner side of the filter screen 33, and scrape off the particulate debris accumulated inside the drum 3, and discharge it through the chip discharge port 34 at the rear side.

[0037] Furthermore, referring to Figure 2 , 3 The upper side of the perfusion cylinder 2 is provided with front and rear filter groups, the front filter group includes a plurality of filter ports 1 22, the rear filter group includes a plurality of filter ports 23, and the diameter of the filter ports 23 is wider than that of the filter ports 1 22. The inner center of the perfusion cylinder 2 is rotatably connected with a rotating shaft 1 21, and a fixed strip 28 corresponding to the plurality of filter ports 1 22 and the plurality of filter ports 23 is fixed on one side of the rotating shaft 1 21, and a corresponding movable strip 210 is provided on one side of the fixed strip 28, and the fixed strip 28 is consistent with the corresponding movable strip 210 in shape and size ... The fixing strip 28 of the front filter port 1 22 is smaller than the fixing strip 28 of the corresponding rear filter port 23. The above-mentioned filling tube 2 is further divided into upper and lower parts, and the upper half has a smaller specification diameter than the lower half, so as to ensure that when the rotating shaft 1 21 drives the plurality of fixing strips 28 and the plurality of movable strips 210 on the peripheral side to rotate to the upper side, the fixing strips 28 and the movable strips 210 can be rotated into the corresponding filter port, and when rotating to the lower side, the fixing strips 28 and the movable strips 210 rotate inside the filling tube 2 without contacting the lower inner tube wall;

[0038] Furthermore, referring to Figure 2A gear 1 4 located outside the drum 3 is fixed at one end of the rotating shaft 31, and a corresponding meshing gear 2 5 is arranged on the upper side of the gear 1 4. The gear 2 5 is rotatably connected to the drum 3, and a pulley 6 is fixed on the outer side of the gear 2 5. Another pulley 6 is fixed to the front end of the rotating shaft 1 21, and the outer sides of the two pulleys 6 are sleeved with corresponding transmission belts 7, and two guide wheels 8 corresponding to the transmission belts 7 are installed on one side of the drum 3. When the rotating shaft 3 31 is impacted and rotated by sewage in the above-mentioned drum 3, the gear 1 4 connected to its outer end rotates, and the meshing gear 1 4 on the upper side is linked, and the gear 1 4 is meshed. The wheel 14 drives the fixed pulley 6 on the outside to rotate, and through the transmission of the two guide wheels 8, in cooperation with the transmission of the other pulley 6 and the transmission belt 7, the rotating shaft 121 in the filling cylinder 2 rotates, and the rotating shaft 121 drives a plurality of fixed strips 28 and movable strips 210 on the peripheral side to remove impurities from the sewage passing through the filling cylinder 2, and can screen out the strip-shaped impurities in the sewage (including hair, clothing fibers, etc.), among which hair, clothing fibers, etc. are organic pollutants that are difficult to degrade in sewage treatment. Screening out such impurities can greatly improve the degradation efficiency of sewage;

[0039] Furthermore, referring to Figure 2 , 5, 7, 8, two shielding plates 9 are rotatably connected to one side of the perfusion cylinder 2, and the two shielding plates 9 correspond to the front and rear filter groups respectively. A torsion spring is provided at the transition between the shielding plate 9 and the perfusion cylinder 2, and a plug-in block 91 corresponding to the filter port is provided on the inner side of the shielding plate 9. When the above-mentioned driven rotating shaft 21 drives the external fixed bars 28 and the active bars 210 to rotate, they are always rotated from the lower side of the shielding plate 9 to the filter port. Therefore, the setting of the shielding plate 9 can play a certain role in shielding and stopping the swept debris. When the fixed bar 28 contacts the baffle plate 9 plug block 91, the baffle plate 9 transfers out the rotation path of the fixed bar 28. When the fixed bar 28 and the movable bar 210 rotate past the baffle plate 9, the baffle plate 9 will automatically rotate and close to one side surface of the infusion cylinder 2 under the action of the torsion spring. Two collecting plates 10 are arranged on the other side of the infusion cylinder 2. The two collecting plates 10 correspond to the front and rear filter groups respectively, and the collecting plates 10 slide on the infusion cylinder 2 through the two sliding shafts on the infusion cylinder 2, and the sliding shaft is provided with an extrusion plate corresponding to the collecting plate 10. The spring is provided, and the inner side of the collecting plate 10 is provided with a plurality of protrusions corresponding to the filter port, and the protruding part is provided with a scraper 11, the above-mentioned fixed strip 28 and the movable strip 210 on the side of the rotating shaft 21 of the shielding plate 9 are passed, and the collecting plate 10 on the other side enters the filling tube 2 again, and the fixed strip 28 and the movable strip 210 squeeze the passing collecting plate 10, and the outer tip of the fixed strip 28 and the movable strip 210 passes through the corresponding scraper 11 on the inner side of the collecting plate 10, and the scraper 11 can squeeze the fixed strip 28 and the movable strip 210. The strip-shaped debris swept out by the tip of the strip 210 is collected and falls on the surface of the collecting plate 10. The strip-shaped debris falling on the surface of the collecting plate 10 is collected by a separate collecting device to avoid falling into the processing tank 1 below. When the fixed strip 28 completely rotates over the collecting plate 10, the collecting plate 10 is automatically moved back to the initial position by the extrusion spring, and the scraper 11 protruding on the inner side thereof will still enter the corresponding filter port to collect the tip debris passing through the fixed strip 28 and the movable strip 210.

[0040] Furthermore, referring to Figure 3 , 46. The left and right sides of the fixed bar 28 are rotatably connected with connecting rods 29. A torsion spring is provided at the junction of the connecting rod 29 and the fixed bar 28. The outer end of the connecting rod 29 is rotatably connected with a corresponding movable bar 210 on one side, and the left and right sides of the fixed bar 28 are provided with upper and lower limiting blocks corresponding to the connecting rod 29. A rotating shaft 25 that slides forward and backward is provided inside the rotating shaft 1 21. A plurality of sleeves 24 corresponding to the movable bar 210 are fixed on the rotating shaft 25, and a corresponding sleeve 24 is opened on one side of the rotating shaft 1 21. The movable strips 210 slide inside and outside the corresponding sleeve 24, the rear end of the second shaft 25 is fixed with a handle 26, the upper side of the rear end of the first shaft 21 is provided with a latch 27 that slides up and down, and the rear end of the second shaft 25 is provided with two front and rear through holes corresponding to the latch 27, and the spacing between the two through holes is equal to the front and rear sliding distance of the sleeve 24. Correspondingly, the movable strips 210 on the outer side of the shaft can be unfolded and stored as needed. When there are many debris in the sewage, in order to ensure the strip-shaped difficult-to-degrade In order to achieve the effect of removing pollutants from the machine, several movable bars 210 are often displayed. Otherwise, the fixed bar 28 can be used. When the movable bar 210 is specifically unfolded, the latch 27 at the rear end of the second rotating shaft 25 is pulled open, and the connected rotating shaft 25 is pulled backward by the handle 26 and no longer moves. At this time, the front end perforation corresponds to the corresponding perforation on the first rotating shaft 21, and then the latch 27 is inserted to fix the front and rear positions of the second rotating shaft 25 in the first rotating shaft 21. When the second rotating shaft 25 drives the several sleeves 24 connected thereto to slide in the slot, the movable bar 210 therein also moves backward, and makes room for the connecting rod 29 on the fixed bar 28 to rotate. Under the action of the torsion spring, the movable bar 210 connected to the outer end of the connecting rod 29 slides outward and is inserted into the middle filter port of the front and rear fixed bars 28, maintaining the same extended state as the front and rear fixed bars 28. At this time, the density of the front and rear scraping strips is high, which can play a significant removal effect on thinner or more filaments and strips.

[0041] Furthermore, the present application also provides a subsequent sewage degradation treatment idea, which is not the main content of the application, but is only used in conjunction with the present equipment. For the sewage that has passed through two impurity removal processes, it finally enters the treatment tank 1. The treatment tank 1 serves as an anaerobic digester, and uses anaerobic microorganisms to degrade organic matter into biogas (methane) and fertilizer in an anoxic environment. With the support of membrane filtration technology, activated sludge treatment is carried out to further remove soluble organic matter and fine suspended matter, and photocatalysts (such as TiO2) are used to degrade difficult-to-degrade organic pollutants under ultraviolet light. Ozone oxidation is used to remove difficult-to-degrade organic matter and trace pollutants. High-temperature drying and pyrolysis technology are used to convert sludge into solid fuel or fertilizer, and the resources generated during the treatment process (such as phosphorus and nitrogen) are recovered for agricultural or industrial applications.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
