Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, in particular to a filtering device for sewage treatment. Background Art

[0002] Sewage treatment technology refers to the process of removing or transforming pollutants in sewage through physical, chemical, biological and other means to make it meet discharge standards or reuse standards. With the acceleration of industrialization and urbanization, the amount of sewage discharged has increased significantly, and the types and concentrations of pollutants have become increasingly complex. The pollution problem of the environment and water resources has become increasingly serious. Therefore, sewage treatment technology is particularly important.

[0003] In the existing technology, sewage treatment technology still has many shortcomings. First, traditional sewage treatment methods have major problems in energy efficiency and cost. The activated sludge method requires a lot of energy to maintain aerobic reactions, and frequent addition of chemicals, such as flocculants and disinfectants, is required during the treatment process. This not only increases operating costs, but the use of chemical agents may cause secondary pollution to the environment. Secondly, traditional treatment technologies have poor removal effects on certain difficult-to-degrade pollutants, especially for micro-pollutants such as drug residues, hormones, and antibiotics. The removal capacity is limited and cannot effectively purify water sources. With the intensification of environmental pollution, micro-pollutants have become a new problem of water pollution, which is difficult to completely remove through traditional methods. In addition, traditional sewage treatment technologies usually produce a large amount of sludge, especially in biological treatment processes. The treatment and disposal of sludge has always been a major problem in the sewage treatment process. The sludge has a high water content, and most sludge contains harmful substances.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1: Figure 1 , Figure 2As shown, a filtering device for sewage treatment according to an embodiment of the present invention comprises four supporting legs 1, the top ends of the four supporting legs 1 are commonly fixedly connected with a disinfection component 2, one side of the disinfection component 2 is rotatably connected with a collecting component 3, one side of the inner surface of the disinfection component 2 is fixedly connected with a processing component 4, a delivery component 5 fixedly connected to the disinfection component 2 is arranged below the processing component 4, a processing component 2 6 is fixedly connected to the other side of the upper end of the disinfection component 2, the processing component 2 6 is used for separating the sewage on the inner wall of the disinfection component 2, and the delivery component 5 is used for quantitatively delivering flocculant to the sewage filtered by the processing component 4.

[0035] Specifically, after the device is installed in a suitable position through four supporting legs 1, the operator can then open the control terminal set at the front of the device and then adjust the specific parameters. Further, when the sewage enters from the collection component 3, the components inside the treatment component 4 will periodically push the larger impurities such as plastics, leaves, etc., so that they all enter the collection component 3, and the collection component 3 will collect and filter them through the internal components, and then return the filtered water to the inner cavity of the disinfection component 2 again, so as to enter the inner cavity of the delivery component 5. When a certain amount of sewage is stored in the inner cavity of the delivery component 5 After that, it will be discharged, and the discharged water will drive the rotating device at the bottom, so that flocculant will be added according to the amount of water. Then, after the flocculant and the filtered sewage have been precipitated at the bottom of the inner cavity of the disinfection component 2 for a certain period of time, they will be extracted by the treatment component 2 6, and through the cooperation with the internal components of the treatment component 2 6, the products of the flocculant and the sewage will be separated, and the filtered sewage will be temporarily stored in the inner cavity of the treatment component 2 6. Then, when the stored filtered water reaches a certain amount, it will cooperate with the quantitative valve to make the stripped sewage flow downward in the form of a water curtain, thereby cooperating with the disinfection components inside the disinfection component 2, and then disinfecting the filtered water.

[0036] It should be further explained that the control terminal mentioned above is a conventional design in the prior art. In this solution, only its control function is utilized, and its circuit and working principle will not be elaborated in detail.

[0037] In addition, the valve installed at the bottom of the processing component 2 6 mentioned above is a float valve, and its working principle is: when the water in the water tank reaches a certain amount, the float rises under the action of buoyancy and opens the water release valve, and the water flows out; when the water flows out, the valve is closed under the tension of the spring, and the next round of water injection cycle begins;

[0038] Furthermore, by setting up a processing component 1 4 to cooperate with the collection component 3, larger particles can be screened during the initial filtration of the sewage, thereby significantly removing suspended matter and large particle pollutants in the water. Further, when the filtered sewage is cooperated with the delivery component 5, the suspended particles in the sewage can form larger flocs, which are further removed by the processing component 2 6, thereby greatly reducing the turbidity of the water body before disinfection by the disinfection component 2, so that the disinfection component 2 can more effectively penetrate the water body and exert a bactericidal effect.

[0039] For further information, please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the collecting component 3 includes a second shell 31, the top of the second shell 31 is fixedly connected to two supporting columns 32, the upper ends of the two supporting columns 32 are commonly fixedly connected to a water inlet 33, the inner wall of the second shell 31 is slidably connected to a collecting frame 34, the disinfection component 2 includes a first shell 21, the inner wall of the first shell 21 is fixedly connected to an isolation plate 22, the bottom wall of the isolation plate 22 is provided with a guide block 23, and the other side of the isolation plate 22 is fixedly connected to a plurality of ultraviolet disinfection lamps 24, the processing component 1 4 includes a filter plate 41, the upper end of the filter plate 41 is fixedly connected to a matching block 42, the upper end of the matching block 42 is slidably connected to two pushing components 43, the pushing component 43 includes a scraper 431, one side of the two scrapers 431 is commonly fixedly connected to a connecting plate 433, the inner surface of the connecting plate 433 is threadedly connected to a bidirectional threaded rod 432, and the other side of the bidirectional threaded rod 432 is fixedly connected to a transmission wheel 1 434.

[0040] In the present implementation process, after sewage enters the inner cavity of the water inlet 33, the water inlet 33 is inclined, so that the sewage can flow into the inner cavity on one side of the shell 21 and fall into the upper end of the filter plate 41. At this time, the filter plate 41 will perform preliminary filtration on larger materials such as infusion, plastic and other larger impurities. Subsequently, the power source inside the processing component 2 6 will drive the transmission wheel 1 434 to rotate when it is started, so that during the rotation of the transmission wheel 1 434, the bidirectional threaded rod 432 fixedly connected on one side will be driven to rotate. During the rotation of the bidirectional threaded rod 432, since the connecting plate 433 is threadedly connected to the bidirectional threaded rod 432, the connecting plate 433 can drive the scraper 431 to move to one side of the collecting component 3, thereby scraping off larger particles and making them enter the inner cavity of the shell 2 31. Subsequently, the scraper 431 can be reset after reaching the specified position, thereby scraping off the next larger particles.

[0041] It should be further explained that the scraper 431 is arranged in a semicircular arc on one side close to the collecting frame 34 , and its purpose is to clean up larger debris on the surface of the filter plate 41 without causing damage to the surface of the filter plate 41 .

[0042] In addition, it should be noted that the collecting frame 34 mentioned in this solution is provided with a plurality of holes on one side close to the disinfection component 2, so that the collected larger particles of debris can be filtered, so that the filtered sewage can flow into the inner cavity of the delivery component 5 again to wait for the next step of processing;

[0043] For further information, see Figure 6 and Figure 7 As shown, the delivery component 5 includes a shell three 51, the bottom end of the shell three 51 is fixedly connected to the matching component 52, the outer surface of the matching component 52 is wrapped with a transmission belt 1 53, the other side of the transmission belt 1 53 is wrapped with an impeller 54, the matching component 52 includes a shell four 521, the inner wall of the shell four 521 is fixedly connected to a diverter block 524, one side of the shell four 521 and the other side are rotatably connected to a transmission rod 522, the outer surface of the transmission rod 522 is provided with two pushing spiral pieces 523, the two pushing spiral pieces 523 are mirror-imaged, and the sides of the transmission rod 522 that are away from each other are wrapped with the transmission belt 1 53.

[0044] Furthermore, during the implementation of this embodiment, when a certain amount of sewage accumulates in the inner cavity of the shell three 51, the stored sewage will be discharged at one time through the internal induction switch, and the discharged sewage will drive the impeller 54 to rotate. During the rotation of the impeller 54, due to the transmission belt 53, it will drive the transmission rod 522 to rotate. During the rotation of the transmission rod 522, the two pushing spiral pieces 523 fixedly connected to the outer surface will be driven to rotate. Furthermore, because the two pushing spiral pieces 523 are arranged in a mirror image, the flocculant particles can be pushed, and then enter the bottom of the shell one 21 according to the amount of water for the second stage of sedimentation.

[0045] Example 2: This example achieves the purpose of stripping the product after the flocculant and sewage are mixed on the basis of Example 1. For details, please refer to Figure 8 , Fig. 9 and Fig.10As shown, the processing component 2 6 includes a connecting pipe 1 61, one end of the connecting pipe 1 61 is fixedly connected to a water pump 62, the output end of the water pump 62 is fixedly connected to a connecting pipe 2 63, the other end of the connecting pipe 2 63 is slidably connected to a transmission wheel 2 66, one side of the outer surface of the transmission wheel 2 66 is wound with a transmission belt 3 67, the other side of the outer surface of the transmission wheel 2 66 is wound with a transmission belt 2 65, the other side of the transmission belt 2 65 is wound with a motor 64, the other side of the transmission wheel 2 66 is fixedly connected to a stripping component 68, and the bottom end of the stripping component 68 A collecting box 69 is fixedly connected, and a float valve is provided at the bottom end of the collecting box 69; the stripping assembly 68 includes an outer shell 5 681, the inner surface of the outer shell 5 681 is rotatably connected to a power rod 682, the outer surface of the outer shell 5 681 is fixedly connected to a water leakage hole 683, the outer surface of the power rod 682 is provided with a pushing piece 684, the outer surface of the pushing piece 684 is provided with a plurality of filtering holes, the other side of the outer surface of the outer shell 5 681 is provided with a discharge hole 685, and the other side of the outer surface of the power rod 682 is provided with two symmetrically arranged water outlet holes 686.

[0046] Specifically, when the flocculant in the inner cavity of the shell 21 is fully mixed and precipitated, the control panel fixedly connected to one side of the shell 21 will send a signal to the water pump 62, so that the connecting pipe 61 fixedly connected to the input end of the water pump 62 can extract it, and then discharge it into the power rod 682 through the connecting pipe 2 63 fixedly connected to the output end of the water pump 62. At this time, the motor 64 starts, and then drives the transmission wheel 2 66 to rotate through the transmission belt 2 65, so that when the transmission wheel 2 66 rotates, it will drive the power rod 682 to rotate, and then the flocculant and sewage products discharged from the connecting pipe 2 63 will be discharged from the two water outlets 686, so that the rotating pushing piece 684 will push the flocculant and the precipitated products and sewage in the sewage, and then discharge them to the other side of the disinfection component 2, and then the water is pushed through the pushing piece 684. The sheet 684 continuously pushes the flocculant and the sewage, so that the sewage entering the inner cavity of the outer shell 5 681 is discharged to one side of the outer shell 5 681, and then passes through layers of filtration, so that the sewage coming out of the inner cavity of the leakage hole 683 can be guaranteed to be no longer rich in impurities, and then the sewage enters the inner cavity of the collecting box 69, and is adsorbed by a number of activated carbons arranged inside the collecting box 69. When the sewage in the inner cavity of the collecting box 69 accumulates to a certain amount, it will be discharged through the bottom of the other side of the collecting box 69 in the form of a water curtain, and then cooperated with a number of ultraviolet disinfection lamps 24 fixedly connected to the other side of the isolation plate 22, so as to sterilize it again. Due to the dispersion of the water flow, the pollutants in the water can be exposed to more ultraviolet rays, thereby improving the sterilization efficiency. In addition, the water curtain can effectively reduce the influence of water turbidity and improve the penetration of ultraviolet rays.

[0047] It should be further explained that: activated carbon is arranged on one side of the inner cavity of the collection box 69, so that when the stripped sewage flows out from the leakage hole 683, the impurities inside the sewage can be re-adsorbed immediately, and the float valve is installed on the other side of the collection box 69, and they will not be affected by each other;

[0048] Furthermore, the opening at the bottom of the other side of the collecting box 69 is in an arc shape. If a person skilled in the art wants to further optimize this, he only needs to use limited sewage to form a short water curtain.

[0049] Furthermore, the water pump 62, the motor 64 and the flocculant in this solution are all very mature technical means in the prior art, and this solution will not elaborate on their working principles and circuit connections.

[0050] Working principle: when in use, the device must first be installed in a suitable position through four supporting legs 1, and then the operator can open the control end set at the front of the device, and then adjust the specific parameters. After the sewage enters the inner cavity of the water inlet 33, the water inlet 33 is set inclined, so that the sewage can flow into the inner cavity on one side of the shell 21 and fall into the upper end of the filter plate 41. At this time, the filter plate 41 will perform preliminary filtration on larger materials such as infusion, plastic and other larger impurities. Subsequently, the power source inside the processing component 2 6 will drive the transmission wheel 434 to rotate when it is started, so that the transmission wheel 434 will drive the bidirectional threaded rod 432 fixedly connected on one side to rotate during the rotation, and in the double During the rotation of the bidirectional threaded rod 432, since the connecting plate 433 is threadedly connected to the bidirectional threaded rod 432, the connecting plate 433 can drive the scraper 431 to move to one side of the collecting component 3, so as to scrape off larger particles and make them enter the inner cavity of the shell 2 31. Then, the scraper 431 can be reset after reaching the specified position, so as to scrape off the next larger particles, and then the sewage will enter the shell 3 51. When a certain amount of sewage is accumulated in the inner cavity of the shell 3 51, the stored sewage will be discharged at one time through the internal induction switch, and the discharged sewage will drive the impeller 54 to rotate, and the impeller 54 will drive the transmission belt 1 53 during the rotation. The rod 522 rotates internally, and during the rotation of the transmission rod 522, the two pushing spiral pieces 523 fixedly connected to the outer surface are driven to rotate. Furthermore, because the two pushing spiral pieces 523 are arranged in a mirror image, the flocculant particles can be pushed, and then enter the bottom of the shell 21 for the second stage of sedimentation according to the amount of water. Subsequently, when the flocculant in the inner cavity of the shell 21 is fully mixed and precipitated, the control panel fixedly connected to one side of the shell 21 will send a signal to the water pump 62, so that the connecting pipe 1 61 fixedly connected to the input end of the water pump 62 can extract it, and then discharge it into the power rod 682 through the connecting pipe 2 63 fixedly connected to the output end of the water pump 62. At this time, the motor 64 is started, and then the water is pumped out through the connecting pipe 2 The transmission belt 2 65 drives the transmission wheel 2 66 to rotate, so that when the transmission wheel 2 66 rotates, it will drive the power rod 682 to rotate, and then the products of flocculant and sewage discharged from the connecting pipe 2 63 will be discharged from the two water outlet holes 686, so that the rotating push piece 684 will push the flocculant and the products after precipitation in the sewage and the sewage, and then discharge them to the other side of the disinfection component 2, and then the water pushes the flocculant and sewage continuously through the push piece 684, so that the sewage entering the inner cavity of the outer shell 5 681 is discharged to one side of the outer shell 5 681, and then through layer by layer filtration, it is ensured that the sewage coming out of the inner cavity of the leakage hole 683 is no longer rich in impurities, and then the sewage enters the inner cavity of the collection box 69.It is adsorbed by several activated carbons arranged inside the collection box 69. When the sewage in the inner cavity of the collection box 69 accumulates to a certain amount, it will be discharged through the bottom of the other side of the collection box 69 in the form of a water curtain, and then cooperated with several ultraviolet disinfection lamps 24 fixedly connected to the other side of the isolation plate 22 to sterilize it again. Due to the dispersion of the water flow, the pollutants in the water can be exposed to ultraviolet rays more, thereby improving the sterilization efficiency. In addition, the water curtain can effectively reduce the influence of water turbidity and improve the penetration of ultraviolet rays.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
