Description

Technical Field

[0002] In the field of ecological environment governance, sewage treatment has always been one of the key tasks. At present, in the process of sewage treatment, many sewage treatment equipment use filters as important pre-treatment components to play a key role in removing larger particle impurities.

[0003] However, existing sewage treatment equipment has many problems in the design and use of filter screens. For example, the filter screen usually adopts a planar structure with a single aperture. When intercepting impurities in sewage, this filter screen is easily blocked by larger particles of impurities. For example, in urban sewage treatment plants, a large amount of debris such as leaves, branches, and plastic bags will accumulate on the filter screen in a short period of time, resulting in obstruction of water flow and reduced sewage treatment efficiency.

[0004] Since the filter screen is frequently clogged, it needs to be cleaned manually frequently, which not only increases the labor intensity, but also affects the continuous operation of the equipment. For example, in some small sewage treatment plants, workers may need to clean the filter screen several times a day, which consumes a lot of time and energy.

[0005] And lack of self-cleaning function, traditional filters generally do not have a self-cleaning mechanism, completely relying on manual cleaning or regular replacement of filters to maintain their normal operation. This has brought great inconvenience in practical applications. For example, in some industrial wastewater treatment processes, the impurity content in the wastewater is high, and the filter is blocked quickly. Frequent replacement of the filter is not only costly, but also leads to increased equipment downtime, affecting production progress.

DETAILED DESCRIPTION

[0020] The embodiments will be combined with the drawings in the specification to clearly and completely describe the technical solution of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application. Example

[0021] The present invention provides a sewage treatment equipment for ecological environment treatment, please refer to Figure 1 - Fig.14 , comprising a frame 1 and a discharge pipe 2 and a filter mechanism 3 arranged in the frame 1, a sewage tank 101 is arranged in the frame 1, the filter mechanism 3 is integrally rotatably connected to the frame 1, the discharge pipe 2 is coaxially sleeved in the filter mechanism 3, the discharge pipe 2 is fixedly connected to the frame 1, the discharge pipe 2 is divided into an internal impurity tank 202 and a pump water tank 201 from top to bottom, a first filter plate 2011 is arranged at the bottom of the pump water tank 201, and a pump water pipe 21 is connected to one side of the pump water tank 201; The frame 1 is fixed with a sewage delivery port 11 on one side of the top of the sewage tank 101, and the frame 1 is fixed with an external impurity tank 12 on the top of the sewage delivery port 11. The pump water pipe 21 absorbs the sewage separated and treated by the filtering mechanism 3 from the sewage tank 101 through a water pump.

[0022] For details, please refer to Figure 5 - Fig.10The filtering mechanism 3 includes two groups of symmetrically arranged inner side plates 31, and waterproof slip rings 311 are fixed on the sides of the two groups of inner side plates 31 away from each other. The inner side plates 31 are rotatably connected to the frame 1 through the waterproof slip rings 311. A plurality of support plates 313 are evenly fixed at equal angles between the two groups of opposite sides of the inner side plates 31. The support plates 313 are symmetrically rotatably connected to the side of the sewage tank 101. A connecting seat 34 is provided between the ends of the two groups of outer arc plates 32 away from the supporting plates 313, and the ends of the outer arc plates 32 away from the supporting plates 313 are rotatably connected to the connecting seat 34. The frame 1 is fixed with outer plates 13 on both sides of the sewage tank 101 , and the outer plates 13 are provided with variable diameter guide grooves 131 . Both ends of the connecting seat 34 are fixed with guide sliders 343 corresponding to the variable diameter guide grooves 131 .

[0023] Furthermore, the radius of the outer arc plate 32 is equal to the radius of the sewage bin 101, and a fourth scraper 121 is fixed to one side of the outer impurity bin 12. The radius of the variable diameter guide groove 131 on the side close to the fourth scraper 121 is larger than the radius of the other side of the variable diameter guide groove 131. When the guide slider 343 runs to the maximum radius of the variable diameter guide groove 131, the two groups of outer arc plates 32 are turned outward to form a complete arc surface structure, and the end of the fourth scraper 121 conflicts with the arc surface formed by the two groups of outer arc plates 32.

[0024] During actual use, sewage containing a large amount of impurities is discharged from the sewage delivery port 11 into the sewage bin 101. At this time, the filter mechanism 3 rotates clockwise as a whole. During this process, the variable diameter guide groove 131 cooperates with the guide slider 343 at the end of the connecting seat 34 to drive the two groups of outer arc plates 32 to be concave to form an impurity removal space. Under the continuous rotation of the filter mechanism 3, the impurities are pushed upward from the sewage bin 101 to the external impurity bin 12 by the impurity removal space between the two groups of external arc plates 32. Since the radius of the variable diameter guide groove 131 here is increased, the connecting seat 34 moves outward with the guidance of the guide slider 343, so that the two groups of external arc plates 32 form a complete arc surface. The impurities on the outside of the two groups of external arc plates 32 are automatically scraped away by the fourth scraper 121 and enter the external impurity bin 12, thereby effectively removing and separating some impurities in the sewage bin 101, and preventing the blockage of the external arc plate 32 and the reduction of the pumping efficiency of the pump water pipe 21.

[0025] See also Figure 3 - Figure 4It should be noted that a rubber block 341 is fixed in the middle of the connecting seat 34, and a rotating seat 342 is fixed at both ends of the rubber block 341. The end of the outer arc plate 32 away from the support plate 313 is rotatably connected to the rotating seat 342. The rubber block 341 is used to flexibly connect the outer arc plate 32, which can effectively prevent the outer arc plate 32 from being squeezed or pulled during the continuous relative flipping action, and can effectively avoid the reciprocating deformation of the outer arc plate 32 causing structural fatigue damage, thereby improving the service life of the outer arc plate 32.

[0026] For further information, see Figure 5 - Figure 6 The inner plate 31 is further provided with two groups of symmetrically arranged inner arc plates 33 between two adjacent groups of support plates 313. The apertures of the filter holes on the first filter plate 2011, the inner arc plate 33 and the outer arc plate 32 are gradually increased. The outer arc plate 32, the inner arc plate 33 and the first filter plate 2011 are used to grade and filter the sewage in the sewage bin 101 to improve the water quality pumped by the outer impurity bin 12. The ends of the two groups of inner arc plates 33 away from each other are rotatably connected to the inner plate 31. Two groups of symmetrically arranged linkage arc arms 344 are fixed at both ends of the connecting seat 34. An arc slide groove 3441 is provided at one end of the linkage arc arm 344 away from the connecting seat 34. An end of the inner arc plate 33 away from the inner plate 31 is slidably connected in the corresponding arc slide groove 3441.

[0027] When the two sets of outer arc plates 32 form a concave impurity removal space under the guidance of the variable diameter guide groove 131, the connecting seat 34 moves inward synchronously, and the linkage arc arm 344 is used to push the inner arc plate 33 to shrink to form a second complete arc surface. At this time, the sewage in the sewage tank 101 uses the pump suction force of the outer impurity tank 12 to pass through the outer arc plate 32, the inner arc plate 33 and the first filter plate 2011 in sequence for graded filtration; When the two groups of outer arc plates 32 form a complete arc surface under the guidance of the variable diameter guide groove 131, the connecting seat 34 moves outward synchronously, and the linkage arc arm 344 is used to drive the two groups of inner arc plates 33 to turn outward. Furthermore, the connection nodes of the support plate 313 and the inner arc plate 33 are fixed with port baffles 314. The top of the inner impurity bin 202 is provided with an impurity inlet 2021, and the sewage bin 101 is also provided with a water level gauge. The water level gauge is used to control the water level in the sewage bin 101 not to be higher than the impurity inlet 2021, which can prevent the sewage that has not been deeply filtered by the first filter plate 2011 from entering the discharge pipe 2. At this time, the turned-out inner arc plate 33 does not conflict with the port baffle 314, and the medium-sized particle impurities collected on the outside of the inner arc plate 33 use their own inertia to fall from the outside of the inner arc plate 33 into the inner impurity bin 202, and are transported to the outside of the frame 1 by the rotating spiral blades 22, forming a solid-water separation action.

[0028] In order to further improve the effect of separating medium-sized particle impurities on the outer side of the inner arc plate 33, cleaning rollers 5 are provided on the outer walls of the opposite sides of the two groups of inner arc plates 33, and a third scraper 51 is fixed to one side of the cleaning roller 5. The cleaning roller 5 and the inner arc plate 33 are elastically connected by a tension spring 52. When the two groups of inner arc plates 33 relatively form a second complete arc surface, the two groups of cleaning rollers 5 use the tension of the tension spring 52 to fit close to the outer wall of the inner arc plate 33. When the inner arc plate 33 begins to turn outward, the two groups of cleaning rollers 5 are displaced away from each other along the outer wall of the inner arc plate 33 by the tension of the tension spring 52, and the large particle impurities on the outer wall of the inner arc plate 33 are further cleaned by the third scraper 51, thereby improving the traceable filtering performance of the inner arc plate 33.

[0029] It should be noted that, in the present embodiment, a spiral blade 22 is also rotatably connected in the inner impurity bin 202, one end of the spiral blade 22 extends through the discharge pipe 2 and is fixed with a driven gear 221, a drive motor 4 is fixed to one side of the outer wall of the frame 1, and a drive gear 41 meshing with the driven gear 221 is fixed to the output end of the drive motor 4, and a driven gear ring 312 meshing with the drive gear 41 is fixed to one end of the waterproof slip ring 311. During the rotation of the spiral blade 22, the impurities falling into the inner impurity bin 202 will be pushed outward, so as to separate the impurities. Since the diameter of the driven gear ring 312 is larger than the driven gear 221, the overall rotation speed of the filter mechanism 3 is less than the speed of the spiral blade 22, so that the filter mechanism 3 as a whole will not rotate too fast, resulting in insufficient filtering and separation.

[0030] For further information, see Fig.10 - Fig.11 A first scraper 3131 is fixed to one side of the support plate 313 close to the sewage tank 101, and a second scraper 315 is fixed to the other side of the support plate 313. The second scraper 315 conflicts with the outer wall of the discharge pipe 2, and the first scraper 3131 conflicts with the inner wall of the sewage tank 101. The support plate 313 is also provided with a through force reduction hole 3132. When the filter mechanism 3 rotates as a whole, the first scraper 3131 can rotate to scrape off impurities adhered to the inner wall of the sewage tank 101, and follow the rotation of the filter mechanism 3 to transport them to the external impurity bin 1 2, the second scraper 315 can rotate to scrape off impurities on the outer wall of the first filter plate 2011, and follow the rotation of the filtering mechanism 3 to enter the inner impurity bin 202, so as to achieve the purpose of automatic classification of impurities and reduce the classification process of subsequent impurity treatment. In order to further improve the cleaning effect of the filter holes of the first filter plate 2011 and the outer arc plate 32, the second scraper 315 and the fourth scraper 121 are both brush structures. When they collide with the first filter plate 2011 and the outer arc plate 32, the brush structure can extend into the filter hole to prevent the filter hole itself from being blocked.

[0031] The present invention can perform graded filtration and separation on the sewage entering the sewage bin 101 through the cooperation between the filtering mechanism 3 with the outer arc plate 32 and the inner arc plate 33 and the discharge pipe 2 with the first filter plate 2011, wherein large particles of impurities enter the outer impurity bin 12, and medium and small particles of impurities enter the inner impurity bin 202 of the discharge pipe 2, and the materials are transported and returned by the spiral blades 22. The outer arc plate 32 and the inner arc plate 33 have an anti-clogging function, can operate continuously without maintenance, can effectively improve the sewage treatment efficiency, have market prospects, and are suitable for promotion and application.

[0032] The above is only the best implementation method adopted by this application in combination with current actual needs, but the protection scope of this application is not limited to this.
