Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a rotary slurry hanging device. Background Technology

[0002] The treatment of oily wastewater from oilfields involves multiple steps, one of which is removing the floating oil and scum from the top of the wastewater. There are several existing technologies for removing floating oil and scum. The first type is a scraper, installed on top of the oily wastewater storage tank and driven by a chain. The disadvantage of this is that it can only be installed on square tanks, not round tanks, and its size is "tailor-made" for square tanks; once removed, it cannot be used on tanks of other sizes. The second type is a chain-driven rotating screen, such as CN214914009U. Its drawback is that this equipment is bulky and inconvenient to move, therefore it can only treat a limited area of ​​floating oil and scum. Utility Model Content

[0003] To address the problems in the background technology, this utility model provides a rotary sludge removal device. This utility model is not picky about the shape of the tank; it can be used with round tanks, square tanks, and even irregularly shaped tanks. This application is small in size and floats in the sludge and oily wastewater during use. By being pushed by external force, this utility model can remove floating oil and sludge over a larger area.

[0004] The technical solution provided by this utility model is: a rotary slurry-coating device, including a frame, a motor, a rotary impeller, a sludge collection tank, and an oil recovery tank; the motor is fixedly mounted on the frame, and the output shaft of the motor can rotate relative to the frame. The output shaft of the motor is connected to the rotary impeller, thereby realizing the rotation of the rotary impeller driven by the motor. The rotary impeller includes a hollow cylinder located in the center, which rotates with the rotation of the motor. Slurry-coating blades with bends are fixedly installed on the outer side of the hollow cylinder. During the rotation of the hollow cylinder, the slurry-coating blades float the upper layer of floating oil. The sludge is hung up, and the hollow cylinder between two adjacent sludge-hanging blades has sludge passage holes on its wall that connect the inside and outside. The floating oil and sludge hung up by the sludge-hanging blades enter the inner side of the hollow cylinder through the sludge passage holes. The sludge collection tank is located inside the hollow cylinder with its opening facing upwards. The floating oil and sludge that enter the inner side of the hollow cylinder fall into the sludge collection tank from the upper opening. The sludge collection tank is fixedly connected to the frame. The sludge recovery tank is connected to the sludge collection tank, and the lowest point of the sludge recovery tank is lower than that of the sludge collection tank, so that the sludge and sludge in the sludge collection tank automatically flow into the sludge recovery tank.

[0005] A further technical solution is that the motor is a dual-head motor, and there are two rotary impellers, which are respectively set at both ends of the motor, thereby making the structure more symmetrical and doubling the processing capacity.

[0006] A further technical solution is: the barbs on the blades of the slag-hanging paddle are used for hanging slag slurry, and the free ends of the barbs are inclined toward the hollow cylinder.

[0007] A further technical solution is that an adjusting bolt is provided between the waste oil recovery tank and the frame to adjust the height of the waste oil recovery tank relative to the frame.

[0008] A further technical solution is that the frame has a mounting box, and the motor is located in the mounting box, thereby avoiding contact between the motor and the sludge and wastewater.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] 1. This utility model floats on top of oily and sewage storage tanks and is not limited by the shape of the tank, thus having few limitations in its use.

[0011] 2. This utility model is small in size and simple in structure. It can move freely on the storage tank by external force, thus enabling the collection and removal of floating oil and scum over a larger area.

[0012] 3. This utility model has two rotating impellers, which not only makes the structure more symmetrical, but also doubles the processing capacity.

[0013] 4. The barbs on the blades of the slag-removing impeller of this utility model can better remove floating oil and slag. Attached Figure Description

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0018] like Figure 1 and Figure 2As shown, this embodiment discloses a rotary sludge-hanging device, the structure of which includes a frame 3, a motor 5, a rotary impeller 4, a sludge collection tank 6, and a sludge and oil recovery tank 1. The motor 5 is fixedly mounted on the frame 3, and the output shaft of the motor 5 can rotate relative to the frame 3. The output shaft of the motor 5 is connected to the rotary impeller 4, thereby realizing the rotation of the rotary impeller 4 driven by the motor 5. The rotary impeller 4 includes a hollow cylinder 403 located in the center. The hollow cylinder 403 rotates with the rotation of the motor 5. Sludge-hanging blades 401 with bends are fixedly installed on the outer side of the hollow cylinder 403. During the rotation of the hollow cylinder 403, the sludge-hanging blades 401 hang up the upper layer of floating oil and sludge. As the hollow cylinder 403 continues to rotate, the hung floating oil and sludge flow down towards the hollow cylinder 403 between two adjacent sludge-hanging blades 401. The hollow cylinder 403 between adjacent slag-hanging blades 401 has slag-passing holes 402 on its wall, connecting the inside and outside. Floating oil and slag lifted by the slag-hanging blades 401 enter the inner side of the hollow cylinder 403 through the slag-passing holes 402. A sludge collection trough 6 is located inside the hollow cylinder 403, with its opening facing upwards. Floating oil and slag entering the inner side of the hollow cylinder 403 fall into the sludge collection trough 6 through its upper opening, achieving initial collection of floating oil and slag. The sludge collection trough 6 is fixedly connected to the frame 3 to ensure it does not rotate. The sludge recovery tank 1 is connected to the sludge collection trough 6 via a flexible hose, and the lowest point of the sludge recovery tank 1 is lower than that of the sludge collection trough 6, allowing the sludge and slag in the sludge collection trough 6 to automatically flow into the sludge recovery tank 1.

[0019] The motor 5 is a dual-head motor 5, and there are two rotary impellers 4, which are respectively set at both ends of the motor 5, thereby making the structure of this application more symmetrical. Both rotary impellers 4 can carry floating oil and sludge slurry, thus doubling the processing capacity.

[0020] The barbs 404 on the blade 401 of the slag-coating paddle are used for coating slag slurry. The free end of the barbs 404 is inclined toward the hollow cylinder 403. The barbs 404 serve to increase the amount of oil coated, which is beneficial to better remove floating oil and slag.

[0021] An adjusting bolt 2 is provided between the sludge recovery tank 1 and the frame 3 to adjust the height of the sludge recovery tank 1 relative to the frame 3. The sludge recovery tank 1 also functions as a float. For sludge and oily wastewater of different densities, the appropriate height of the slag-hanging impeller blade 401 relative to the liquid surface can be adjusted by adjusting the height of the sludge recovery tank 1. In this application, the sludge recovery tank 1 can be connected to a ground-based oil pump via a hose, thereby ensuring that the sludge recovery tank 1 is never completely filled.

[0022] The frame 3 is equipped with a mounting box, and the motor 5 is located in the mounting box, thereby preventing the motor 5 from coming into contact with sludge and wastewater.

[0023] In summary, this embodiment floats on top of the oily and sewage storage tank during use, has no requirements on the shape of the storage tank, and the frame 3 can be moved by external force, thereby enabling the complete removal of floating oil and scum.
