Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to fig. 1 to 5, but the scope of the present utility model is not limited to the following description.

Example 1

A sewage treatment device, as shown in fig. 1 and 2, comprises a sedimentation tank 100 with a filter screen 110 arranged inside, wherein a water inlet pipe 120 is arranged on the side wall of the sedimentation tank 100 and below the filter screen 110; the sedimentation tank 100 is further provided with a flushing device, and a water outlet of the flushing device is aligned to the top surface of the filter screen 110; a discharge port is provided on a side of the settling tank 100 away from the water inlet pipe 120, as shown in fig. 5, and a discharge door 130 is provided on the discharge port. Further, as shown in fig. 1, the flushing device includes a plurality of nozzles 140 disposed on an inner top wall of the settling tank 100, a branch pipe 150 communicating with a water inlet end of the nozzles 140 and penetrating through the top wall of the settling tank 100, a main pipe 160 jointly communicating with water inlet ends of the branch pipes 150, and a water tank communicating with the water inlet ends of the main pipe 160, where the main pipe 160 is provided with a water pump, and both the water pump and the water tank are not shown in the drawing. Further, as shown in fig. 1 and 2, a telescopic device for moving the filter screen 110 in the vertical direction is further disposed in the settling tank 100. Further, the telescopic device includes a hydraulic rod 170 disposed on the inner top wall of the settling tank 100, and a telescopic end of the hydraulic rod 170 is connected to the top surface of the filter screen 110. Further, as shown in fig. 1 and 2, the telescopic device includes a sliding block 180 disposed on a side wall of the filter screen 110, and a vertical sliding groove 190 disposed on an inner wall of the settling tank 100 and slidably engaged with the sliding block 180.

In specific implementation, the discharging door 130 is closed, so that the discharging door 130 is sealed with the settling tank 100; then, the medical sewage is added into the sedimentation tank 100 along the water inlet pipe 120, and in order to improve the sedimentation effect, in practical implementation, a feeding pipe (not shown in the figure) can be arranged on the side wall where the water inlet pipe 120 is positioned, namely, a flocculating agent is added into the sedimentation tank 100 to flocculate suspended matters or some tiny impurities, so as to improve the sedimentation speed; the medical sewage gradually overflows the filter screen 110 in the continuous introduction process, the sewage is filtered by the filter screen 110 in the process of overflowing the filter screen 110, and then the sewage overflowing the filter screen 110 is introduced into a sterilizing device (not shown in the figure) for sterilizing. When sewage continuously passes through the filter screen 110, impurities in the sewage continuously adhere to the bottom surface of the filter screen 110, and partial precipitation continuously falls along with the progress of filtration, so that generally, the precipitation on the upper part of medical sewage is less, and therefore, the filter screen 110 is generally required to be moved to the upper position of the precipitation tank 100 through the hydraulic rod 170, and in the process, the sliding block 180 slides up along the vertical sliding chute 190, so that the stability is improved. After the introduction of the medical wastewater is completed, as the wastewater above the filter screen 110 is introduced into the sterilizing device, the wastewater on the upper portion is gradually reduced and even is flush with the filter screen 110, at this time, in order to achieve the purpose of filtering the wastewater on the lower portion in the settling tank 100, the hydraulic rod 170 is made to adjust the filter screen 110 to move down, in the process, the sliding block 180 slides down in the vertical sliding groove 190 until sliding to the bottom wall of the vertical sliding groove 190, and the bottom wall of the vertical sliding groove 190 is very close to the bottom of the settling tank 100, so that at this time, less unfiltered wastewater remains on the bottom of the settling tank 100. If a large amount of sediment is attached to the bottom surface of the filter screen 110 in the filtering process, the filter screen 110 needs to be washed, specifically, the hydraulic rod 170 drives the filter screen 110 to move upwards, then a water pump is started, water in the water tank rapidly flows to the spray head 140 along the main pipe 160 and the branch pipe 150 under the action of the water pump, and then is sprayed to the top surface of the filter screen 110 through the spray head 140, so that the purpose of back washing the filter screen 110 is achieved; thereafter, the discharge door 130 is opened to discharge the remaining sewage and sediment along the discharge door 130, thereby achieving the purpose of collecting the sediment.

Example 2

On the basis of embodiment 1, as shown in fig. 1, 3 and 4, the discharging door 130 includes a filtering door 131 and a blocking door 132 disposed at the discharging hole, in this embodiment, the filtering door 131 and the blocking door 132 are both hinged at the discharging hole, and the filtering door 131 is disposed at one side inside the settling tank 100 (this principle is the same as the split screen principle). Further, as shown in fig. 1, the bottom wall of the discharge port is flush with the inner bottom wall of the settling tank 100. Further, as shown in fig. 1, 3 and 4, a scraper 200 and a pull rod 210 connected with the scraper 200 are disposed at the bottom of the settling tank 100; the side wall and the bottom wall of the scraper 200 are respectively abutted against the inner wall and the inner bottom wall of the sedimentation tank 100, and the water inlet pipe 120 is arranged above the scraper 200; the end of the pull rod 210 away from the scraper 200 is disposed near the discharge door 130. Further, the scraping plate 200 is a silica gel scraping plate 200.

In particular, during the back flushing process, some water flows into the sediment at the bottom of the sedimentation tank 100, so that more water is in the sediment, and therefore, when the sediment is collected, the sediment and the water are mixed, which is difficult to realize effective separation, specifically, when the sediment needs to be collected, the blocking door 132 is opened, as shown in fig. 4, after that, the excessive water flows out along the filtering door 131, the outside of the sedimentation tank 100 can be collected, when the water in the sediment is less, the filtering door 131 is opened (at this time, the blocking door 132 and the filtering door 131 are simultaneously opened), after that, the staff pulls the free end of the pull rod 210, so that the scraper 200 moves towards the direction of the discharge outlet, and then scrapes the sediment from the discharge outlet, thereby realizing the collection of the sediment and improving the operation convenience.
