Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a sewage purification device for environmental protection. Background Art

[0002] The field of sewage treatment technology mainly involves the removal and purification of various pollutants in sewage to meet the requirements of environmental emission standards or reuse standards. Sewage filtration is a key link in sewage treatment, aiming to remove suspended particles and impurities in sewage. It uses specific filter media such as filter plates, filter screens, sand filter layers, etc. When sewage flows through these media, the solid particles in them are intercepted, thereby purifying the sewage.

[0003] Chinese patent publication number CN212550123U discloses a sewage filter box, comprising: a filter box body, a first mounting shaft, a second mounting shaft, a filter screen and a drive mechanism; the first mounting shaft and the second mounting shaft are rotatably connected to two opposite inner walls of the filter box body, the two ends of the filter screen are detachably connected to the first mounting shaft and the second mounting shaft respectively, one end of the first mounting shaft and the second mounting shaft are rotatably connected to the box cover, and the other end penetrates the filter box body and is fixedly connected to the drive mechanism.

[0004] The aforementioned patent utilizes a drive mechanism to synchronously rotate the first and second mounting shafts, enabling rapid filter screen replacement. This solves the difficulty of replacing filters in the prior art and improves filter screen replacement efficiency. However, sewage is filtered through a static sedimentation process, which relies entirely on gravity to allow impurities to naturally settle, resulting in a very slow process. The precipitation of even tiny particles often requires a significant amount of time. Therefore, the present invention provides a sewage purification device for environmental protection. Utility Model Content

[0005] The purpose of the utility model is to provide a sewage purification device for environmental protection. By arranging filter plates 1 and 2 in an inclined state, the sewage has a certain fluidity when being filtered, thereby achieving a better filtering effect. The sewage passes through the filter plates 1 and 2 with a certain inclination angle, and relies on the fluidity of the sewage itself to achieve rapid filtration.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sewage purification device for environmental protection, comprising a clean water bucket, wherein the top of the clean water bucket is fixedly connected to a top cover, the top of the top cover passes through the interior of the clean water bucket and is fixedly connected to a water inlet pipe, the interior of the clean water bucket is fixedly connected to a filter plate 1 near the top, the interior of the clean water bucket is fixedly connected to a filter plate 2 at the bottom of the filter plate 1, the tops of the filter plates 1 and 2 are both rotatably connected to scrapers, the tops of the two scrapers are fixedly connected to universal joints, and a universal joint is also fixedly connected between the scrapers near the top and the universal joints near the bottom, the bottom of the top cover is rotatably connected to a rotating shaft, and the bottom of the rotating shaft is fixedly connected to the top of the universal joint near the top.

[0007] Preferably, a motor is fixedly connected to the top of the top cover, and an output shaft of the motor passes through the bottom of the top cover and is fixedly connected to the top of the rotating shaft.

[0008] Preferably, a solid plate is fixedly connected to the bottom of the filter plate 2 inside the clean water bucket, and a water outlet frame communicating with the interior of the clean water bucket is fixedly connected to the bottom of the clean water bucket.

[0009] Preferably, the filter plate 1, the filter plate 2 and the solid plate are all arranged in an inclined state, the inclination direction of the filter plate 1 is opposite to the inclination direction of the filter plate 2, the inclination direction of the filter plate 2 is consistent with the inclination direction of the solid plate, and the inclination angle of the filter plate 2 is consistent with the inclination angle of the solid plate.

[0010] Preferably, a sewage pipe is fixedly connected to the outer surface of the clean water bucket, and placement grooves are provided inside the wall of the clean water bucket at the lowest position of the top of filter plate one and at the lowest position of the top of filter plate two. A baffle is slidably connected inside the placement groove, and three springs are fixedly connected between the side of the baffle and the placement groove.

[0011] Preferably, two through grooves are opened through the inner wall of the wall of the clean water barrel, the baffle passes through the side of the placement groove and is located inside the through groove, the inner wall of the baffle passes through the through groove and is located inside the clean water barrel and is fixedly connected with a shift block, and both through grooves are connected to the interior of the sewage pipe.

[0012] Preferably, the sewage pipe is arranged in a spiral shape, and the shift block and the scraper are adaptively matched.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1) By setting the filter plates 1 and 2 in an inclined state, when the sewage is filtered through the filter plates 1 and 2, since the filter plates 1 and 2 are inclined devices, the sewage will have a certain fluidity when it falls on the top of the filter plates 1 and 2, thereby making the filtering effect better. The sewage passes through the filter plates 1 and 2 with a certain inclination angle and relies on the fluidity of the sewage itself to achieve rapid filtration.

[0015] 2) By setting up scrapers, when filtering sewage, the motor is started to drive the rotating shaft to rotate, and then three universal joints are provided to drive the two scrapers to rotate on the top of filter plate 1 and filter plate 2 respectively, thereby stirring the sewage, further enhancing the fluidity of the sewage, and further improving the filtering effect.

[0016] 3) By setting a baffle to cooperate with the shift block, when the scraper rotates to the shift block position, it will drive the shift block to slide along the through slot, and then drive the baffle to slide along the placement slot. The three springs are compressed. When the shift block is slid to the rightmost side of the through slot, the baffle completely enters the interior of the placement slot. At this time, the interior of the clean water bucket and the sewage pipe are connected through the through slot, so that the filtered debris will enter the interior of the sewage pipe through the through slot, and then the debris filtered by the filter plate 1 and the filter plate 2 can be quickly discharged, avoiding the accumulation of debris on the surface of the filter plate 1 and the filter plate 2, thereby ensuring the filtering capacity of the filter plate 1 and the filter plate 2.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] Combine Figure 1 - Figure 5 A sewage purification device for environmental protection comprises a clean water bucket 1, the top of the clean water bucket 1 is fixedly connected to a top cover 2, the top of the top cover 2 passes through the interior of the clean water bucket 1 and is fixedly connected to a water inlet pipe 3, the interior of the clean water bucket 1 is fixedly connected to a filter plate 6 near the top, the interior of the clean water bucket 1 is fixedly connected to a filter plate 2 7 at the bottom of the filter plate 1 6, the tops of the filter plates 1 6 and 2 are both rotatably connected to a scraper 8, the tops of the two scrapers 8 are fixedly connected to a universal joint 9, and a universal joint 9 is also fixedly connected between the scraper 8 near the top and the universal joint 9 near the bottom, the bottom of the top cover 2 is rotatably connected to a rotating shaft 10, and the bottom of the rotating shaft 10 is fixedly connected to the top of the universal joint 9 near the top.

[0026] During actual operation, the water inlet pipe 3 is connected to the external conveying device to transport the sewage to the inside of the clean water barrel 1, and then the sewage is filtered through the filter plate 1 6 and the filter plate 2 7. The filtered water will fall to the top of the solid plate 11, and then be discharged through the water outlet frame 12, and then the purified sewage will be collected by the external collection device.

[0027] Specifically, when the sewage is filtered through the filter plate 1 6 and the filter plate 2 7, since the filter plate 1 6 and the filter plate 2 7 are inclined devices, the sewage will have a certain fluidity when it falls to the top of the filter plate 1 6 and the filter plate 2 7, thereby making the filtering effect better. The sewage passes through the filter plate 1 6 and the filter plate 2 7 with a certain inclination angle, relying on the fluidity of the sewage itself to achieve rapid filtration, while the static sedimentation filtration relies entirely on gravity to allow impurities to settle naturally, and the speed is very slow, especially for the precipitation of some tiny particles, which often takes a long time.

[0028] Specifically, when filtering sewage, the motor 5 is started to drive the rotating shaft 10 to rotate, and then the three universal joints 9 are provided to drive the two scrapers 8 to rotate on the top of the filter plate 1 6 and the filter plate 2 7 respectively, thereby stirring the sewage, so that the fluidity of the sewage is further enhanced, and the filtering effect is further improved.

[0029] See Figure 2 The top of the top cover 2 is fixedly connected to a motor 5 , and the output shaft of the motor 5 passes through the bottom of the top cover 2 and is fixedly connected to the top of the rotating shaft 10 .

[0030] See Figure 2 and Figure 3 The interior of the clean water bucket 1 is located at the bottom of the filter plate 2 7 and is fixedly connected with a solid plate 11 , and the bottom of the clean water bucket 1 is fixedly connected with a water outlet frame 12 that communicates with the interior of the clean water bucket 1 .

[0031] See Figure 2 and Figure 3, filter plate 1 6, filter plate 2 7 and solid plate 11 are all arranged in an inclined state, the inclination direction of filter plate 1 6 is opposite to the inclination direction of filter plate 2 7, the inclination direction of filter plate 2 7 is consistent with the inclination direction of solid plate 11, and the inclination angle of filter plate 2 7 is consistent with the inclination angle of solid plate 11.

[0032] See Figure 4 and Figure 5 The outer surface of the clean water bucket 1 is fixedly connected to the sewage pipe 4, and the wall of the clean water bucket 1 is provided with placement grooves 13 at the lowest position of the top of the filter plate 1 6 and the lowest position of the top of the filter plate 2 7. The inside of the placement groove 13 is slidably connected to a baffle 14, and three springs 17 are fixedly connected between the side of the baffle 14 and the placement groove 13.

[0033] Specifically, when the scraper 8 rotates to the position of the shift block 16, it will drive the shift block 16 to slide along the through groove 15, and then drive the baffle 14 to slide along the placement groove 13. The three springs 17 are compressed. When the shift block 16 is slid to the rightmost side of the through groove 15, the baffle 14 completely enters the interior of the placement groove 13. At this time, the interior of the clean water bucket 1 is connected to the sewage pipe 4 through the through groove 15, so that the filtered debris will enter the interior of the sewage pipe 4 through the through groove 15, and then the debris filtered by the filter plate 1 6 and the filter plate 2 7 can be quickly discharged, avoiding the accumulation of debris on the surface of the filter plate 1 6 and the filter plate 2 7, thereby ensuring the filtering capacity of the filter plate 1 6 and the filter plate 2 7.

[0034] Specifically, since filter plate 1 6 and filter plate 2 7 are both in an inclined state, the scraper 8 is not in continuous contact with the shift block 16. When the shift block 16 is slid to the rightmost side of the through slot 15, the scraper 8 continues to rotate so that the scraper 8 is no longer in contact with the shift block 16. At this time, the three springs 17 rebound, causing the baffle 14 to reset, re-closing the through slot 15, thereby ending the sewage discharge operation.

[0035] See Figure 5 Two through grooves 15 are opened inside the wall of the clean water bucket 1, and the baffle 14 passes through the side of the placement groove 13 and is located inside the through groove 15. The inner wall of the baffle 14 passes through the through groove 15 and is located inside the clean water bucket 1 and is fixedly connected with a shift block 16. Both through grooves 15 are connected to the interior of the sewage pipe 4.

[0036] See Figure 1 and Figure 4 The sewage pipe 4 is arranged in a spiral shape, and the shift block 16 is adaptively matched with the scraper 8.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
