Description

Technical Field

[0001] This utility model relates to the technical field of thermal power plants, specifically to a separation device. Background Technology

[0002] Thermal power plants generate a large amount of wastewater during power generation. This wastewater contains a lot of impurities, and if it is discharged directly, it will pollute the environment. Therefore, it needs to be separated by a separation device.

[0003] A separation device for wastewater treatment in thermal power plants, disclosed in publication number CN214781151U, includes: a main body, filter plates, a water distribution plate, a rotating rod, blades, side plates, and an arc-shaped plate. The main body contains a separation component, and one end of the separation component has a sedimentation component. The aforementioned device uses a handle and a push rod to drive a brush head to clean larger particles of impurities on the inclined filter plates. It also opens the sealing plug to push the larger particles of impurities into a collection box outside the main body for unified collection and treatment, preventing excessive impurities from clogging the filter plates and affecting wastewater treatment efficiency.

[0004] However, the aforementioned separation device has an inclined guide plate inside, which is prone to accumulating dirt and causing insufficient dirt separation. At the same time, the simple mixing structure of the aforementioned separation device leads to insufficient mixing of flocculant and sewage, resulting in poor flocculation effect. Therefore, we propose a separation device to solve the problems mentioned above. Utility Model Content

The packing assembly 11 includes a feeding box 1101, which is fixed to the side of the separation box 1. A feeding port 1102 is provided on the upper side of the feeding box 1101. A second water pump 1103 is installed below the feeding box 1101 at the upper end of the separation box 1. One side of the second water pump 1103 is connected to the feeding box 1101 through a connecting pipe 1104, and the other end of the second water pump 1103 is connected to... A conveying pipe 1105 is provided, and the end of the conveying pipe 1105 is connected to a collecting pipe 1106 embedded on the surface of the separation box 1. The lower end of the collecting pipe 1106 is evenly provided with a discharge port 1107, which can discharge the flocculant inside the feeding box 1101 into the collecting pipe 1106 through the second water pump 1103, so that the discharge port 1107 below the collecting pipe 1106 can discharge the flocculant into the separation box 1, so as to facilitate the flocculation of sewage. A drain door 12 is installed on the front side of the separation box 1.

[0027] Working principle: First, during use, sewage is discharged into the separation tank 1 through the inlet pipe 2. The separation tank 1 is equipped with a first guide plate 4, a second guide plate 5, and a third guide plate 6 arranged in an inclined manner, which facilitates the flow of sewage. During the flow, the first water pump 1001 on the flushing assembly 10 can be turned on, which allows the first flushing head 1005 on the surface of the first water collection pipe 1004, the second flushing head 1008 on the surface of the second water collection pipe 1007, and the third flushing head 1011 on the surface of the third water collection pipe 1010 to flush the surfaces of the third guide plate 6, the second guide plate 5, and the first guide plate 4, respectively, so as to prevent sewage from adhering and accumulating on the guide plates.

[0028] The separation box 1 is equipped with a filter assembly 8. The first filter screen 802 on the filter assembly 8 is located at the lower end of the first guide plate 4, and the second filter screen 804 on the filter assembly 8 is located at the lower end of the second guide plate 5, so as to facilitate the filtration of sewage flowing down the first guide plate 4 and the second guide plate 5. At the same time, the filter assembly 8 is connected to the opening 7 on the surface of the separation box 1 through the first rubber blocking plate 801 and the second rubber blocking plate 803, so as to facilitate the pulling of the handle 806 to remove the filter assembly 8 from the separation box 1 for cleaning of the first filter screen 802 and the second filter screen 804.

[0029] During separation, the flocculant inside the feed box 1101 can be introduced through the connecting pipe 1104 by turning on the second water pump 1103 on the packing assembly 11, and discharged into the collection pipe 1106 through the conveying pipe 1105 so that the flocculant can be discharged into the sewage below from the discharge port 1107. Then, by turning on the drive motor 901 on the stirring assembly 9, the first rotating shaft 903 drives the second rotating shaft 904 to rotate synchronously through the transmission belt 906, so that the stirring blades 905 on the surfaces of the first rotating shaft 903 and the second rotating shaft 904 can mix the sewage and flocculant inside. The stirring blades 905 on the surfaces of the first rotating shaft 903 and the second rotating shaft 904 are staggered to improve the mixing effect of the device. The mixed and precipitated dirt can be discharged from the drain door 12. This is the working principle of the separation device.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
