A sewage treatment device for construction projects

Abstract

The present invention relates to the technical field of sewage treatment, and discloses a sewage treatment device for construction projects, including a base plate, the top of which is fixedly connected to a storage tank. When the device sends sewage into the base plate, the sewage will first pass through filter screen 2 for preliminary filtration. Since filter screen 2 is arranged at an angle, pollutants will accumulate on one side of filter screen 2. As filter screen 2 rotates, impurities accumulated on it will be taken away, and water will flow downward through filter screen 2. During the rotation of filter screen 2, impurities on the net will be removed by a cleaning component. In this way, before this part of filter screen 2 reaches the bottom again, the surface of filter screen 2 is clean. Such a setting can ensure that the device can continuously filter out impurities in sewage without affecting normal operation, and at the same time ensure that the filter screen will not be blocked.

[0022] The working principle of this embodiment is as follows: when the equipment treats sewage, the sewage enters from the temporary storage box 204, and then the sewage enters the outer shell 202, where it is filtered by the filter component 21 to remove impurities in the sewage. The filtered sewage then enters the cavity three 209, and the chemical agent is sprayed into the sewage through the nozzle device. At the same time, the motor two 2018 drives the stirring rod 2019 to rotate, thereby improving the mixing effect of the sewage and the chemical agent. As the sewage continues to accumulate in the cavity three 209, the sewage will flow from the connecting groove 2010 to the cavity two 208, and solid-liquid separation will be carried out under the filtration of the rotating component 23. After that, the debris generated in the filter component 21 and the rotating component 23 will accumulate above the filter net one 2013 in the cavity one 207. The staff only needs to clean the cavity three 209 regularly. The operation is simple, and the operation process does not affect the normal filtration of the equipment.

[0023] Example 2: Based on Example 1, please refer to Figure 5-Figure 7 The filter assembly 21 includes an annular column 211, the outer wall of the annular column 211 is rotatably connected to the housing 202 through a bearing, the outer wall of the annular column 211 is fixedly connected to a gear 212, the gear 1 2014 is meshed with the gear 212, the inner wall of the annular column 211 is fixedly connected to a filter screen 213, and the inner wall of the filter screen 213 is rotatably connected to the cleaning assembly 22 through a bearing.

[0024] The cleaning assembly 22 includes a connecting pipe 221, the outer wall of which is rotatably connected to the filter screen 213 through a bearing, the inner wall of the housing 202 is fixedly connected to the connecting pipe 221, the bottom of the connecting pipe 221 passes through the cavity 3 209 and extends to the inside of the cavity 1 207, the outer wall of the connecting pipe 221 is fixedly connected to the base 201, the outer wall of the connecting pipe 221 is provided with a notch 225, the outer wall of the connecting pipe 221 is fixedly connected to a connecting plate 222, and the outer wall of the connecting plate 222 is connected to the outer wall of the connecting pipe 221 through the shaft. The bearing is rotatably connected to a pressure roller 223. Since the pressure roller 223 is placed at the bottom of the filter screen 213, pressure is applied to the bottom of the filter screen 213, so that the top of the filter screen 213 can fit with the scraper 224, ensuring that impurities on the filter screen 213 accumulate on the scraper 224. As debris accumulates on the scraper 224, the debris will be sent into the connecting pipe four 221 through the notch 225 and fall onto the filter screen 1 2013. The outer wall of the connecting pipe four 221 is fixedly connected to the scraper 224.

[0025] The working principle of this embodiment is as follows: when sewage enters above the second filter screen 213, the sewage will be filtered, and the filtered debris will accumulate on the second filter screen 213. As the motor drives the gear 1 2014 to rotate, the rotating gear 1 2014 drives the annular column 211 to rotate through the gear 212. The rotation of the annular column 211 drives the second filter screen 213 to rotate. The rotating filter screen 213 pushes the filtered debris onto the scraper 224, and the scraper 224 cleans the debris on the second filter screen 213. After cleaning, the sewage is filtered again.

[0026] Example 3: Based on Example 1, please refer to Figure 8 The rotating component 23 includes a hollow gear 231, the inner wall of the cavity 208 is rotatably connected to the hollow gear 231, the hollow gear 231 is meshed with the driving gear 2011, the inner wall of the hollow gear 231 is fixedly connected with an annular filter 232, the inner wall of the annular filter 232 is fixedly connected with a raised plate 234, the end of the annular filter 232 away from the hollow gear 231 is fixedly connected with an annular plate 233, and the end of the annular plate 233 away from the annular filter 232 is rotatably connected to the cavity 208 through a bearing.

[0027] The working principle of this embodiment is as follows: when the chemically treated sewage enters the annular filter 232, the liquid will flow downward through the annular filter 232, and the debris will accumulate on the annular filter 232. As the annular filter 232 rotates, the raised plate 234 on the annular filter 232 will drive the debris to be lifted up, until the raised plate 234 is placed on the top of the annular filter 232, the debris brought up by the raised plate 234 will fall into the connecting frame 2012 and slide to the top of the filter 2013.
