[0041] Reference Figures 1 to 4 A wastewater treatment device according to an embodiment of the present invention includes a tank 100, an inlet pipe 200, and a wastewater collection tank 500. The tank 100 defines a receiving cavity 110 with a top opening, which is used to hold wastewater. The inlet pipe 200 is located at the center of the tank 100, and its bottom is connected to a wastewater supply pump. The outlet 222 at the top of the inlet pipe 200 faces downward, and when the receiving cavity 110 is full of wastewater, the outlet 222 is below the water surface. The wastewater collection tank 500 is located on the outer peripheral wall of the tank 100 and is used to collect wastewater overflowing from the upper part of the tank 100. The wastewater collection tank 500 is connected to a wastewater conveying pipe to transport the wastewater collected in the wastewater collection tank 500 to the next wastewater treatment device.

[0042] The wastewater treatment device of this utility model embodiment also includes a slag leveling structure 300 and an oil floating collection structure 400. The slag leveling structure 300 is installed in the receiving cavity 110 and is located at the lower part of the inlet pipe 200. The slag leveling structure 300 can rotate around the inlet pipe 200. By setting the slag leveling structure 300, which can rotate around the inlet pipe 200, in the receiving cavity 110, the impurities at the bottom of the receiving cavity 110 can be leveled, thereby facilitating the collection and treatment of impurities. The slag leveling structure 300 rotates slowly around the inlet pipe 200, which can form vertical turbulence in the receiving cavity 110, offsetting the impact of the incoming water flow and facilitating the rapid sedimentation of impurities. An oil slick collection structure 400 is installed at the top of the inlet pipe 200 to collect oil slicks on the surface of sewage. Vertically, the outlet 222 is lower than the bottom of the sewage collection tank 500. The bottom of the inlet pipe 200 is connected to the sewage supply pump, but the outlet 222 at the top of the inlet pipe 200 faces downwards and is lower than the bottom wall of the sewage collection tank 500. This reduces the impact of the incoming water flow, facilitates the sedimentation of impurities, and improves sewage treatment efficiency. The oil slick collection structure 400 collects oil slicks on the surface of sewage, facilitating further sewage treatment.

[0043] It should be noted that the slag leveling structure 300 is connected to a drive device that drives it to rotate around the water inlet pipe 200, and the slag leveling structure 300 is preferably rotated slowly to avoid the slag leveling structure 300 generating eddies in the receiving cavity 110 that affect the sedimentation of impurities.

[0044] In the embodiments of this utility model, reference is made to Figure 1 As shown, the inlet pipe 200 includes a main water pipe 210 and a water distribution cap 220. The bottom of the main water pipe 210 is connected to the sewage supply pump, and the water distribution cap 220 is installed on the top of the main water pipe 210. The water distribution cap 220 has a water distribution chamber 221 with its opening facing downwards. An outlet 222 is formed between the inner wall of the water distribution chamber 221 and the outer wall of the main water pipe 210. The bottom of the outlet 222 is located below the top of the main water pipe 210. When the tank 100 is full of sewage, the top of the main water pipe 210 is below the sewage level. The water distribution cap 220 installed on the top of the main water pipe 210 can buffer the incoming sewage and reduce the impact of the water flow. The outlet 222 being located below the water level can also effectively reduce the impact of the water flow, thereby facilitating the rapid sedimentation of impurities.

[0045] In an embodiment of this utility model, a slag discharge port 140 is provided at the bottom of the barrel 100, and a water inlet pipe 200 passes through the slag discharge port 140. Specifically, refer to... Figure 1 , Figure 2 As shown, the main water pipe 210 passes through the slag discharge port 140. The slag discharge port 140 is closed when the tank 100 is in normal use. When the tank 100 runs for a set time or when the impurities settled in the tank 100 exceed the set weight, the slag discharge port 140 opens to discharge slag from the bottom of the tank 100.

[0046] Furthermore, in order to facilitate the discharge of impurities inside the receiving cavity 110 and the cleaning of the inside of the receiving cavity 110, a cleaning pipe 150 is connected to the middle of the barrel 100. The cleaning pipe 150 can supply clean water into the receiving cavity 110 to facilitate the cleaning of the inside of the receiving cavity 110 and the cleaning of the slag-leveling structure 300.

[0047] In an embodiment of this utility model, the bottom wall of the receiving cavity 110 is inclined; along the vertical direction, the edge of the bottom wall of the receiving cavity 110 is higher than its center position. Specifically, refer to... Figure 1 , Figure 2 As shown, the bottom wall of the receiving cavity 110 is high at the edge and low in the middle, and the middle part of the bottom wall of the receiving cavity 110 is connected to the edge of the slag discharge port 140. The bottom wall of the receiving cavity 110 is inclined so that the sedimented impurities can accumulate in the middle position of the bottom of the receiving cavity 110, which facilitates subsequent discharge.

[0048] In an embodiment of this utility model, along the radial direction of the water inlet pipe 200, the distance between the lower surface of the slag leveling structure 300 and the bottom wall of the receiving cavity 110 gradually decreases. Specifically, refer to... Figure 1 , Figure 2 As shown, the lower surface of the slag leveling structure 300 can be a horizontal or inclined surface, but as it extends outward along the radial direction of the water inlet pipe 200, the distance between the lower surface of the slag leveling structure 300 and the bottom wall of the receiving cavity 110 gradually decreases. That is, the distance between the lower surface of the slag leveling structure 300 near the water inlet pipe 200 and the bottom wall of the receiving cavity 110 is larger, while the distance between the lower surface of the slag leveling structure 300 away from the water inlet pipe 200 and the bottom wall of the receiving cavity 110 is smaller. This makes it easier for the slag leveling structure 300 to level the impurities settled at the bottom of the receiving cavity 110, so that more impurities accumulate in the middle position of the bottom of the receiving cavity 110, which facilitates the subsequent cleaning and discharge of impurities.

[0049] In embodiments of this utility model, multiple leveling structures 300 are provided, and the multiple leveling structures 300 are arranged at intervals around the circumference. Specifically, it is preferable to have two leveling structures 300, which are symmetrically arranged about the inlet pipe 200, and both leveling structures 300 are hollow structures, or frame structures. When the two hollow leveling structures 300 rotate, they can only generate small eddies within the receiving cavity 110. The generated eddies will not stir up the impurities at the bottom of the receiving cavity 110, while simultaneously impacting the water flow generated by the inlet pipe 200, thereby stabilizing the water flow in the entire sewage tank within the receiving cavity 110 and facilitating the sedimentation of impurities.

[0050] It can be assumed that the number of leveling structures 300 can be adjusted according to the diameter of the barrel 100. Generally speaking, it is preferable that the number of leveling structures 300 is even, and the number of leveling structures 300 should not be too many. Too many leveling structures 300 will also interfere with the sedimentation of impurities to the bottom of the receiving cavity 110.

[0051] In an embodiment of this utility model, the oil spill collection structure 400 includes an oil spill scraper 410 and a collection box 420. The oil spill scraper 410 is rotatably mounted on the water inlet pipe 200, and the collection box 420 is mounted on the inner wall of the receiving cavity 110. The collection box 420 is connected to an oil drain pipe 430. Specifically, refer to... Figure 1 , Figure 4As shown, the end of the oil scraper 410 is provided with an oil collection net 411, the surface of which can adsorb oil. The collection box 420 is provided with a scraper 421, which is used to scrape off the oil adsorbed on the surface of the oil collection net 411. During the process of the scraper moving around the water inlet pipe 200, the oil will adhere to the surface of the oil scraper 410, and then move along the oil scraper 410 to the end of the oil scraper 410 under the action of centrifugal force, and be adsorbed on the oil collection net 411. There is only one collection box 420 in the barrel 100. When the oil scraper 410 passes over the collection box 420, the oil adsorbed on the oil collection net 411 will be scraped away by the scraper 421 and then discharged through the oil drain pipe 430.

[0052] In an embodiment of this utility model, a drain hole 120 penetrating the inner wall of the barrel 100 is provided on the upper part of the inner wall. Wastewater in the receiving cavity 110 enters the wastewater collection tank 500 through the drain hole 120. A baffle plate 130 is installed on the barrel 100, and the baffle plate 130 is movably and vertically mounted on the barrel 100 to seal the drain hole 120. Specifically, refer to... Figure 1 , Figure 3 As shown, when the receiving cavity 110 is full of sewage, there are generally fewer sewage impurities at the top of the receiving cavity 110. However, it is also necessary to minimize the entry of floating oil into the sewage collection tank 500. Therefore, the drain hole 120 is located on the upper part of the inner side wall of the tank 100. This ensures that there are fewer sewage impurities entering the sewage collection tank 500 and also greatly reduces the amount of floating oil entering the sewage collection tank 500. The baffle plate 130 is connected to a power structure 131 that drives it to move vertically. When water is stored in the receiving cavity 110, the power structure 131 drives the baffle plate 130 to rise to seal the drain hole 120. When the water level in the receiving cavity 110 exceeds the drain hole 120 and reaches the set water level, the power structure 131 drives the baffle plate 130 to fall to open the drain hole 120, allowing the water in the receiving cavity 110 to flow into the sewage collection tank 500.
