[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention sets a blocking mechanism. When sewage impurities with a high speed enter the placement sleeve, the sewage will flow out through the leaking port, and the impurities will hit the disc, so that the second rotating shaft and the disc will rotate. At this time, the speed of the impurities will be reduced and fall onto the subsequent structure. If the impurities are attached to the disc due to moisture, the disc will collide with the top rod, so that the attached objects will fall off the disc.

[0018] 2. The present invention sets an anti-clogging mechanism. Flocs are prone to cause clogging at the water outlet, so an isolation sleeve is set. The flocs will be blocked by the isolation sleeve. At the same time, the force of the water flow will be transmitted to the water stirring plate, so that the rotating shaft three rotates, and then drives the support rod one and the scratching plate to scratch the outer surface of the isolation sleeve, thereby preventing a large amount of flocs from completely covering the isolation sleeve.

[0019] 3. The present invention sets a top-layer filtering mechanism. After the sewage flows into the top layer, the double blocking effect of the curved plate and the raised block will make the flow of the sewage very slow, so that the fine sand particles in the sewage are gradually accumulated between the top plate and the raised block, so that the fine sand particles in the sewage that cannot be isolated by the filter plate are separated from the water.

[0020] 4. The present invention sets a differential mechanism and rotates the handle 2 90 degrees, so that the biological film is parallel to the water flow direction. The water flow will drive the film scraper to move along the support rod 2, thereby scraping off the particles on the biological film.

[0021] 5. The present invention will occasionally drive the partition and the raised block to move upward for a distance through the telescopic rod. At the same time, the nozzle will spray the clean water in the clean water tank to wash the partition and the raised block, and drive the sand on the top plate to flow to the bottom. The sewage with sand will flow into the sewage pool through the original position of the handle.

[0022] 6. The present invention provides a water storage unit. The rotation of the rotating disk and the centrifugal plate will cause the water to produce a centrifugal effect, thereby moving particles smaller than 150 μm to the periphery of the storage tube. At this time, the water in the center of the storage tube does not contain particles. The water is then pumped out through the water pump three and the water pipe and flows into the high-pressure injection device, thereby facilitating the subsequent high-pressure injection process.

DETAILED DESCRIPTION

[0041] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0042] Example 1, using Figure 1-Figure 17 A sewage multi-stage filtration treatment device according to one embodiment of the present invention is described as follows.

[0043] like Figure 1-Figure 3 As shown, a sewage multi-stage filtering treatment device of the present invention comprises a vehicle body 1, a bottom plate 2 is fixedly connected to the top of the vehicle body 1, an outer shell 3 is fixedly connected to the top of the bottom plate 2, a top cover 4 is rotatably connected to the top of the outer shell 3, an opening plate 5 is rotatably connected to the side of the outer shell 3, a placement rack 6 is fixedly connected to the outer surface of the outer shell 3, the placement rack 6 is used to place some tools such as external pipes, a side of the outer shell 3 close to the opening plate 5 is fixedly connected to a high-pressure injection device 12, a vacuum suction unit 7 is fixedly connected to the top of the bottom plate 2, a water pump 10 is fixedly connected to the outer surface of the vacuum suction unit 7, a filtering treatment unit 8 is fixedly connected to the end of the water pump 10 away from the vacuum suction unit 7, a water pump 2 11 is fixedly connected to the outer surface of the filtering treatment unit 8, and a water storage unit 9 is fixedly connected to the end of the water pump 2 11 away from the filtering treatment unit 8;

[0044] When the present invention is working, first connect the external water pipe to the vacuum suction unit 7, the vacuum suction unit 7 will suck the sewage to be absorbed through the water pipe and perform preliminary filtration, then the sewage will enter the filtration treatment unit 8 through the water pump 10 for deep re-filtration and purification, and finally enter the water storage unit 9 through the water pump 2 11 for centrifugal action and be used by the high-pressure injection device 12.

[0045] like Figure 4-Figure 6 As shown, the vacuum suction unit 7 includes a vacuum chamber 71, a water pipe 72 is fixedly connected to the bottom of the vacuum chamber 71, a cover plate 73 is rotatably connected to the top of the vacuum chamber 71, a rotating shaft 74 is rotatably connected to the outer surface of the vacuum chamber 71, a sealing plate 75 is fixedly connected to the outer surface of the rotating shaft 74, a joint 76 is fixedly connected to one end of the vacuum chamber 71 close to the rotating shaft 74, a vacuum pump 79 is fixedly connected to the top of the inner wall of the vacuum chamber 71, a depth filter plate mechanism 78 is slidably connected to the bottom of the vacuum chamber 71, a blocking mechanism 77 is fixedly connected to one end of the inner wall of the vacuum chamber 71 close to the joint 76, and a primary filter plate 710 is fixedly connected to the inner wall of the vacuum chamber 71;

[0046] By rotating shaft 1 74 , the joint 76 on the vacuum chamber 71 can be connected to the external water pipe, and then the vacuum pump 79 will extract the air in the vacuum chamber 71 , so that the vacuum chamber 71 becomes a negative pressure, so that the external sewage is sucked into the vacuum chamber 71 .

[0047] like Figure 7-Figure 8 As shown, the blocking mechanism 77 includes a placement sleeve 771, the inner wall of which is evenly provided with water leakage holes 772, the top of the placement sleeve 771 is fixedly connected to a top rod 773, the outer surface of the placement sleeve 771 is fixedly connected to a support plate 1 774, the outer surface of the support plate 1 774 is rotatably connected to a rotating shaft 2 775, and the bottom of the rotating shaft 2 775 is fixedly connected to a disc 776.

[0048] Since the principle of vacuum sewage suction is to rely on the vacuum pump to extract the air in the sewage suction tank to form negative pressure, so that the sewage is sucked into the tank, but since the impurities in the sewage are uncertain, when the vacuum adsorption force sucks the sewage impurities in the external pipe into the vacuum chamber 71, some of the sewage impurities with heavier weight will enter the vacuum chamber 71 at a very fast speed, thereby hitting the inner wall on the other side of the vacuum chamber 71 and cannot be collected. When this happens, the sewage impurities at a very fast speed will enter the placement sleeve 771, the sewage will flow out through the leak 772, and the impurities will hit the disc 776, thereby causing the rotating shaft 775 and the disc 776 to rotate. At this time, the speed of the impurities will decrease and fall onto the subsequent structure. If the impurities are attached to the disc 776 due to moisture, the disc 776 will collide with the top rod 773, thereby causing the attached objects to fall from the disc 776.

[0049] The bottom of the vacuum chamber 71 is fixedly connected to the top of the bottom plate 2, the outer surface of the placement sleeve 771 is fixedly connected to the inner wall of the vacuum chamber 71, and the end of the water pipe 72 away from the vacuum chamber 71 is fixedly connected to the outer surface of the water pump 10.

[0050] like Fig. 9 As shown, the depth filter plate mechanism 78 includes a processing plate 781, a handle 782 is fixedly connected to the outer surface of the processing plate 781, a secondary filter plate 783 is symmetrically arranged on the top of the processing plate 781, a water outlet 784 is symmetrically arranged on the processing plate 781, an insertion groove 785 is fixedly connected to one end of the processing plate 781 close to the water outlet 784, and an anti-blocking mechanism 786 is connected to the inner wall pin of the insertion groove 785.

[0051] After the sewage enters the vacuum chamber 71, it will first contact the primary filter plate 710. The primary filter plate 710 will first filter out large particles of impurities in the sewage. Then the sewage will enter the treatment plate 781 and then be filtered by two secondary filter plates 783. Most of the impurities visible to the naked eye in the sewage will be blocked, and finally the sewage will flow out through the outlet 784.

[0052] like Fig.10 As shown, the anti-blocking mechanism 786 includes an isolation sleeve 7861, the outer surface of which is fixedly connected to an insertion plate 7862, the end of the isolation sleeve 7861 away from the insertion sleeve is rotatably connected to a rotating shaft three 7863, the outer surface of the rotating shaft three 7863 is evenly provided with water stirring plates 7864, the end of the rotating shaft three 7863 close to the isolation sleeve 7861 is fixedly connected to a support rod one 7865, and the outer surface of the support rod one 7865 is fixedly connected to a scratch plate 7866.

[0053] In the process of sewage flowing through the outlet 784, due to the smaller cross-section, flocs are prone to blockage at the outlet 784, so an isolation sleeve 7861 is provided, and the flocs will be blocked by the isolation sleeve 7861. At the same time, the force of the water flow will be transmitted to the stirring plate 7864, thereby causing the rotating shaft three 7863 to rotate, and then drive the support rod one 7865 and the scratching plate 7866 to scratch the outer surface of the isolation sleeve 7861, thereby preventing a large amount of flocs from completely covering the isolation sleeve 7861 and hindering the further flow of sewage.

[0054] The bottom of the processing plate 781 is slidably connected to the bottom of the vacuum chamber 71 , the outer surface of the insertion plate 7862 is slidably connected to the inner wall of the insertion groove 785 , and the outer surface of the scratch plate 7866 is in contact with the outer surface of the isolation sleeve 7861 .

[0055] Embodiment 2, use Figure 1-Figure 17 A sewage multi-stage filtration treatment device according to one embodiment of the present invention is described as follows.

[0056] like Figure 11-Figure 12 As shown, a sewage multi-stage filtering treatment device of the present invention is based on the first embodiment, and the filtering treatment unit 8 includes a treatment box 81, the top of the treatment box 81 is fixedly connected with a top plate 82, the side of the treatment box 81 close to the water pump 10 is fixedly connected with a water pipe 2 83, the bottom of the water pipe 2 83 is fixedly connected to the top of the water pump 10, the end of the treatment box 81 away from the water pipe 2 83 is fixedly connected with a water pipe 3 84, the top of the top plate 82 is fixedly connected with a telescopic rod 85, the outer surface of the treatment box 81 is fixedly connected with a sewage pool 89, the side of the treatment box 81 away from the sewage pool 89 is fixedly connected with a clean water tank 810, the top of the clean water tank 810 is fixedly connected with a nozzle 811, the top of the treatment box 81 is fixedly connected with a top filter mechanism 86, the inner wall of the treatment box 81 is fixedly connected with a middle filter plate mechanism, and the bottom of the treatment box 81 is provided with a sedimentation chamber 88.

[0057] like Fig.13As shown, the top-layer filtering mechanism 86 includes a top layer 861, the outer surface of the top layer 861 is fixedly connected to the inner wall of the processing box 81, the top of the top layer 861 is fixedly connected to a bent plate 862, the bottom of the telescopic rod 85 is fixedly connected to a partition 863, both sides of the partition 863 are fixedly connected to raised blocks 864, the end of the bent plate 862 close to the water pipe 83 is fixedly connected to a water retaining plate 865, and the bottom of the raised block 864 is in contact with the top of the top layer 861.

[0058] After the sewage flows into the top layer 861, the dual obstruction of the curved plate 862 and the raised block 864 will slow down the flow of the sewage, causing the fine sand particles in the sewage to gradually accumulate between the top plate 82 and the raised block 864, thereby separating the fine sand particles in the sewage that cannot be isolated by the filter plate from the water.

[0059] like Fig.14 As shown, the middle filtering mechanism 87 includes a middle plate 871, the outer surface of the middle plate 871 is fixedly connected to the inner wall of the processing box 81, the top of the middle plate 871 is fixedly connected to a support plate 872, the outer surface of the support plate 872 is rotatably connected to a rotating block 873, and the inner wall latch of the rotating block 873 is connected to a differential mechanism 874.

[0060] like Fig.15 As shown, the differential mechanism 874 includes a support plate three 8741, the outer surface of the support plate three 8741 is fixedly connected with a block 8742, the end of the support plate three 8741 away from the block 8742 is fixedly connected with a biological film 8746, the upper and lower ends of the support plate three 8741 are symmetrically provided with support plates four 8743, the opposite surface of the support plate four 8743 is fixedly connected with a support rod two 8744, the outer surface of the support rod two 8744 is slidably connected with a film scraper 8745, and the end of the biological film 8746 away from the support plate three 8741 is fixedly connected with a handle two 8747.

[0061] When the sewage enters the middle plate 871, the biofilm 8746 is perpendicular to the direction of water flow. The organic pollutants in the sewage are adsorbed, decomposed and metabolized by the microorganisms on the biofilm 8746, but there will definitely be a small amount of solid impurities in the sewage. The accumulation of these impurities will damage the biofilm 8746. By rotating the handle 8747 ninety degrees, the biofilm 8746 will be parallel to the water flow direction. The water flow will drive the film scraper 8745 to move along the support rod 8744, thereby scraping off the particles on the biofilm 8746.

[0062] When there is no need to clean the sewage, the telescopic rod 85 drives the partition 863 and the protruding block 864 to move upward for a certain distance. At the same time, the nozzle 811 will spray the clean water in the clean water tank 810, thereby flushing the partition 863 and the protruding block 864, and driving the sand on the top plate 82 to flow to the bottom. At this time, the differential mechanism 874 will also be drawn out, and the sewage with sand will flow into the sewage pool 89 through the original position of the handle, thereby realizing the cleaning of the device and avoiding the weakening of the filtering effect.

[0063] like Figure 16-Figure 17 As shown, the water storage unit 9 includes a storage cylinder 91, the outer surface of the storage cylinder 91 is fixedly connected with a water pipe 92, the bottom of the water pipe 92 is fixedly connected to the outer surface of the water pump 2 11, the outer surface of the storage cylinder 91 is fixedly connected with a supporting foot 93, the bottom of the supporting foot 93 is fixedly connected to the top of the bottom plate 2, the top of the storage cylinder 91 is fixedly connected with a cover plate 2 94, the top of the cover plate 2 94 is fixedly connected with a water pump 3 96, the outer surface of the water pump 3 96 is fixedly connected with a water outlet pipe 97, the bottom of the water pump 3 96 is fixedly connected with a water pump pipe 910, the bottom of the storage cylinder 91 is fixedly connected with a servo motor 95, the output end of the servo motor 95 is fixedly connected with a rotating disk 98, the top of the rotating disk 98 is fixedly connected with a centrifugal plate 99, and the top of the cover plate 2 94 is fixedly connected with an ultraviolet lamp 911.

[0064] After multiple filtering processes, particles smaller than 150 μm in the water of the sewage still cannot be removed. A large number of fine particles cause great wear and tear on the spray gun of the high-pressure injection device 12 and the objects of the high-pressure flushing pipe, thereby increasing the cost of use and maintenance. The rotation of the rotating disk 98 and the centrifugal plate 99 driven by the servo motor 95 will cause the water to produce a centrifugal effect, thereby moving those particles smaller than 150 μm to the periphery of the storage tube 91. At the same time, the ultraviolet lamp 911 on the top will also irradiate the water, thereby killing the bacteria and viruses in the sewage, preventing these bacteria and viruses from entering the environment and causing harm to the organisms. At this time, the central water of the storage tube 91 does not contain particulate matter, and the water is then pumped out by the water pump 3 96 and the water pipe 910, and flows into the high-pressure injection device 12, thereby facilitating the subsequent high-pressure injection process.

[0065] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
