These wastewaters need to be purified and treated to meet the standards before they can be discharged to the outside. In the prior art, the components of these wastewaters vary depending on the process, but generally, the wastewater is purified by adding chemical reagents.

In this purification method, the solids produced by the solid-liquid separation generally need to be subjected to filter press treatment. In the prior art, it is common to squeeze the solids through a pressing plate with filter holes to achieve the purpose of filter press. However, this method easily causes the solids to adhere to the inner wall of the filter press box, which is not easy to clean up. Therefore, the utility model proposes a comprehensive wastewater treatment device that can improve the purification efficiency and easily clean the solids after filter press. Utility Model Content

[0027] A rotating tank 3 is installed in the tank cover 4 through a bearing, the upper open end of the rotating tank 3 extends out of the fixed tank 2 and forms a power connection with the motor 5 arranged on the tank cover 4, the lower open end of the rotating tank 3 extends into the fixed tank 2 and is installed with a cover 9, and the cover 9 is configured to switch between an open state and a closed state. Specifically, the bottom of the cover 9 is connected to a telescopic rod 8, and the cover 9 forms a sliding fit with the slide hole. The cover 9 is driven up and down by the telescopic rod 8 to open or close the lower open end of the rotating tank 3. In addition, a plurality of filter holes are arranged in an array on the outer circumferential surface of the rotating tank 3 located in the fixed tank 2.

[0028] An annular tube 10 is disposed on the lower end surface of the fixed tank 2 . The annular tube 10 is connected to the inner cavity of the fixed tank 2 via a connecting hole. A drainage tube 11 extends from the outer surface of the annular tube 10 .

[0029] An auxiliary ring 7 is provided inside the rotating tank 3, and the bottom end of the auxiliary ring 7 is chamfered to form a blade shape. The outer cylindrical surface of the auxiliary ring 7 can fit with the inner wall of the rotating tank 3. The auxiliary ring 7 is driven by the telescopic rod 2 arranged on the tank cover 4 to move in the vertical direction. A power transmission member is provided between the auxiliary ring 7 and the motor 2 6 arranged on the tank cover 4. The active member of the power transmission member is arranged at the output end of the motor 2 6. The driven member of the power transmission member is installed on the outside of the auxiliary ring 7 through a spline and when the auxiliary ring 7 moves, the driven member continuously outputs power to the auxiliary ring 7 through the spline. In addition, a limit bracket for limiting the movement of the driven member is provided on the tank cover 4. The power transmission member and the telescopic rod 2 are not shown in the figure. The telescopic rod 1 8 and the telescopic rod 2 can be existing electric telescopic rod technology and will not be described in detail.

[0030] The inner surface of the auxiliary ring 7 is provided with a plurality of protrusions 12 in an array. The side of the protrusion 12 facing the axis of the auxiliary ring 7 is arranged in a slope shape, and the distance between the slope and the axis of the auxiliary ring 7 increases from bottom to top.

[0031] Working principle of embodiment 1:

[0032] First, the auxiliary ring 7 is driven into the rotating tank 3 by the telescopic rod 2 to block the filter holes on the outer surface of the rotating tank 3. At the same time, the telescopic rod 1 8 drives the sealing cover 9 to block the lower opening of the rotating tank 3.

[0033] Then, the wastewater and the reagent are put into the rotating tank 3 and wait for a period of time to allow a chemical reaction to occur between the two. During this process, the auxiliary ring 7 is driven by the motor 2 6 to rotate at a low speed, and the wastewater is stirred by the protrusion 12 to fully mix the wastewater and the reagent, thereby improving the reaction efficiency and thus improving the purification efficiency;

[0034] After purification is completed, the auxiliary ring 7 is driven to leave the rotating tank 3 by the telescopic rod 2, and the rotating tank 3 is driven to rotate at high speed by the motor 1 5. Under the action of centrifugal force, the liquid will leave the rotating tank 3 through the filter hole, and finally be discharged through the connecting hole, the ring pipe 10 and the drain pipe 11, while the solid remains on the inner wall of the rotating tank 3. This process is to filter and filter press the purified wastewater;

[0035] After the filtration is completed, the auxiliary ring 7 is moved downward by the telescopic rod 2, and the auxiliary ring 7 is driven to rotate at a low speed by the motor 2 6, and the inner wall of the rotating tank 3 is scraped by the bottom blade of the auxiliary ring 7 to clean up the solids;

[0036] Then, the telescopic rod 8 drives the cover 9 to move downward, and the solids piled on the cover 9 move downward together. After leaving the fixed tank 2, the solids on the cover 9 are removed by manual cleaning or the like.

[0037] In the above process, since the auxiliary ring 7 rotates and moves downward, the solids can be easily scraped off the inner wall of the rotating tank 3 , and due to the presence of the protrusions 12 , the scraped solids will not adhere to the inner circumferential surface of the auxiliary ring 7 .

[0038] Embodiment 2

[0039] Reference Figure 3 and Figure 6The cover 9 includes an outer sleeve 901, the upper end surface of the outer sleeve 901 is provided with a bearing groove, a rotating disk 902 is installed in the bearing groove through a bearing, a limit ring is provided at the lower open end of the outer sleeve 901, a driving disk 903 is sleeved in the outer sleeve 901, the driving disk 903 is connected to the telescopic rod 8, and a spring 904 is provided between the driving disk 903 and the upper closed end of the outer sleeve 901; its significance lies in that when the cover 9 is driven to move upward by the telescopic rod 8, after the rotating disk 902 contacts the lower open end of the rotating tank 3, the telescopic rod 8 continues to drive the cover 9 to move upward, compressing the spring 904, thereby improving the sealing performance of the cover 9 to the lower opening of the rotating tank 3. In addition, when the rotating tank 3 rotates at high speed, it will rotate with the rotating disk 902 through friction, and the blocking of the lower opening of the rotating tank 3 remains unchanged.
