Description

Technical Field

[0001] This utility model relates to the field of oil removal flotation technology, and in particular to an oil removal flotation device. Background Technology

[0002] Industrial production, such as petrochemicals and machinery processing, generates a large amount of oily wastewater. Direct discharge of this oily wastewater would severely pollute the environment and damage the ecosystem. Oil flotation treatment equipment has emerged to address this issue. It is a highly efficient wastewater treatment device that operates based on the principle of air flotation. By injecting microbubbles into the wastewater, the bubbles adhere to oil droplets and suspended solids, reducing their overall density to less than water, causing them to float to the surface and be removed by a specialized collection device. This equipment can effectively treat various forms of oil, including dispersed oil and emulsified oil. It is fast, efficient, compact, and easy to operate, providing preliminary purification of wastewater, facilitating subsequent treatment, and ensuring that wastewater meets discharge standards.

[0003] Water treatment only treats the water itself, without addressing the oil and gas in the water. Subsequent processes are needed to process the oil and gas after water treatment, which is cumbersome and inefficient. Therefore, a facility that can simultaneously treat water and oil and gas is needed to improve efficiency.

[0004] An existing patent (publication number: CN213326816U) discloses a simultaneous cyanide removal and oil flotation tank for water treatment, relating to the field of water treatment technology. It includes an oil flotation tank, an oil extractor, and a purification tank. The oil extractor is located on the outer right side of the upper surface of the oil flotation tank, and the right side of the oil extractor is on the same surface as the right side of the oil flotation tank. The purification tank is located at the rear of the oil flotation tank. This oil flotation tank can achieve oil and gas separation simultaneously with water treatment, reducing water treatment steps, improving water treatment efficiency, and reducing costs through the reduction of steps. Furthermore, the design of a float and trigger switch enables automatic opening and closing control of the inlet and outlet, achieving real-time control, reducing the uncertainty of manual operation, and increasing the overall automation level.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, when separating floating oil and impurities, they lack a structure for filtering and recovering the oil and impurities after separation. Therefore, they cannot filter, separate, and recover the oil and impurities, reducing the flexibility of recovering floating oil and impurities after separation.

[0006] Therefore, an oil removal flotation treatment device is proposed. Utility Model Content

[0007] The purpose of this invention is to provide an oil flotation treatment device that solves the problem that existing methods for separating floating oil and impurities lack a structure for filtering and recovering the oil and impurities after separation, thus reducing the flexibility of recovering floating oil and impurities.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an oil removal flotation treatment device, comprising a flotation machine body, a filter cake mechanism, and a recovery mechanism, wherein the filter cake mechanism is bolted to the rear side of the flotation machine body, and the recovery mechanism is bolted to the top of the flotation machine body;

[0009] The filter cake mechanism includes an oil storage box, an electric heating plate, a positioning plate, and a filter plate. The oil storage box is bolted to the rear side of the air flotation machine body, the electric heating plate is bolted to the bottom of the inner side of the oil storage box, the positioning plate is bolted to the top of the oil storage box, and the filter plate is clipped to the inner side of the positioning plate.

[0010] Preferably, the recycling mechanism includes a circulation component and a collection component, wherein the circulation component is bolted to the top of the air flotation machine body, and the collection component is rotatably connected to the inside of the circulation component.

[0011] Preferably, the circulation assembly includes a positioning rod, an electric rotating rod assembly, a guide toothed plate, and a conveyor belt. The positioning rod is bolted to the top of the air flotation machine body, the electric rotating rod assembly is bolted to the inside of the positioning rod, the guide toothed plate is bolted to the surface of the positioning rod, and the conveyor belt is sleeved on the surface of the electric rotating rod assembly.

[0012] Preferably, the collecting assembly includes a transmission toothed tube, a collecting arc plate, a transmission tube, a gravity rotating tube, and a guide spiral plate. The transmission toothed tube is rotatably connected to the inner side of the conveyor belt, and the surface of the transmission toothed tube meshes with the surface of the guide toothed plate. The collecting arc plate is bolted to the surface of the transmission toothed tube, the transmission tube communicates with the inner side of the transmission toothed tube, the gravity rotating tube is rotatably connected to the inner side of the transmission tube, and the guide spiral plate is bolted to the inner side of the transmission tube. The surface of the guide spiral plate is connected to the gravity rotating tube.

[0013] Preferably, an auxiliary rotating ring is rotatably connected to the surface of the conveyor belt, and the inner side of the auxiliary rotating ring is rotatably connected to the surface of the transmission tooth tube.

[0014] Preferably, a reinforcing angle plate is bolted to the surface of the positioning rod, and the bottom of the reinforcing angle plate is bolted to the top of the air flotation machine body.

[0015] Preferably, an auxiliary rotating plate is rotatably connected to the surface of the transmission tooth tube, and the inner side of the auxiliary rotating plate is in contact with the surface of the guide tooth plate.

[0016] Preferably, an auxiliary guide plate is snapped onto the surface of the collecting arc plate, and the auxiliary guide plate is arc-shaped.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application sets up an air flotation machine body and a filter cake mechanism. The air flotation machine body is an existing air flotation machine. The oil storage box can store the oil sludge separated by the recovery mechanism. The electric heating plate can heat the stored oil to prevent the oil from solidifying. The positioning plate can cooperate with the filter plate to filter the oil and impurities, thereby separating the oil and impurities. Furthermore, the impurities and oil can be recovered separately by removing the filter plate from the positioning plate, which improves the flexibility of oil and impurity recovery.

[0019] 2. This application, by setting up a recycling mechanism, allows the circulation component to cooperate with the collection component. A positioning rod limits the electric rotating rod assembly and the guide tooth plate, enabling the electric rotating rod assembly to drive the conveyor belt in reciprocating motion. This, in turn, drives the transmission tooth tube in reciprocating motion and allows the transmission tooth tube to rotate along the guide tooth plate. The transmission tooth tube can cooperate with the collecting arc plate, transmission pipe, gravity rotating pipe, and guide spiral plate. The rotation of the transmission tooth tube drives the collecting arc plate to rotate on the air flotation machine body. This allows the collecting arc plate to collect oil and impurities from the surface of the liquid within the air flotation machine body and transport them to the gravity rotating pipe. The gravity rotating pipe remains parallel to the gravity square due to gravity, allowing for temporary storage of oil and impurities. The guide spiral plate then transports the oil and impurities to the filter cake mechanism, improving the flexibility of oil and impurity recovery. Attached Figure Description

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] An oil removal flotation treatment device includes a flotation machine body 1, a filter cake mechanism 2, and a recovery mechanism 3. The filter cake mechanism 2 is bolted to the rear side of the flotation machine body 1, and the recovery mechanism 3 is bolted to the top of the flotation machine body 1.

[0030] The filter cake mechanism 2 includes an oil storage box 21, an electric heating plate 22, a positioning plate 23, and a filter plate 24. The oil storage box 21 is bolted to the rear side of the air flotation machine body 1, the electric heating plate 22 is bolted to the bottom of the inner side of the oil storage box 21, the positioning plate 23 is bolted to the top of the oil storage box 21, and the filter plate 24 is clipped to the inner side of the positioning plate 23.

[0031] In this embodiment: by setting up an air flotation machine body 1 and a filter cake mechanism 2, the air flotation machine body 1 is an existing air flotation machine equipment, the oil storage box 21 can store the oil sludge separated by the recovery mechanism 3, the electric heating plate 22 can heat the stored oil to prevent the oil from solidifying, the positioning plate 23 can cooperate with the filter plate 24 to filter the oil and impurities through the filter plate 24, thereby separating the oil and impurities, and the impurities and oil can be recovered separately by removing the filter plate 24 from the positioning plate 23, which improves the flexibility of oil and impurity recovery.

[0032] Specifically, such as Figure 4 As shown, the recycling mechanism 3 includes a circulation component 31 and a collection component 32. The circulation component 31 is bolted to the top of the air flotation machine body 1, and the collection component 32 is rotatably connected to the inside of the circulation component 31.

[0033] Specifically, such as Figure 5 As shown, the circulation assembly 31 includes a positioning rod 311, an electric rotating rod assembly 312, a guide toothed plate 313, and a conveyor belt 314.

The surface of the guide spiral plate 325 is connected to the gravity transfer tube 324.

[0035] In this embodiment: by setting up the recycling mechanism 3, the circulation component 31 can cooperate with the collection component 32. The positioning rod 311 limits the electric rotating rod assembly 312 and the guide tooth plate 313, allowing the electric rotating rod assembly 312 to drive the conveyor belt 314 to reciprocate, thereby driving the transmission tooth tube 321 to reciprocate, and allowing the transmission tooth tube 321 to rotate along the guide tooth plate 313. The transmission tooth tube 321 can cooperate with the collection arc plate 322, the transmission tube 323, the gravity rotating tube 324, and the guide spiral plate 325. The transmission toothed tube 321 rotates, which drives the collecting arc plate 322 to rotate on the air flotation machine body 1. This allows the collecting arc plate 322 to collect oil and impurities from the liquid surface inside the air flotation machine body 1 and transport the oil and impurities to the gravity transfer tube 324. The gravity transfer tube 324 remains parallel to the gravity square due to gravity, thus temporarily storing the oil and impurities. The guide spiral plate 325 then transports the oil and impurities to the filter residue mechanism 2, improving the flexibility of oil and impurity recovery.

[0037] Specifically, such as Figure 5 As shown, a reinforcing angle plate 5 is bolted to the surface of the positioning rod 311, and the bottom of the reinforcing angle plate 5 is bolted to the top of the air flotation machine body 1.

[0038] In this embodiment: by setting an auxiliary rotating ring 4, which can cooperate with the conveyor belt 314, the auxiliary rotating ring 4 can provide auxiliary guidance at the connection between the conveyor belt 314 and the transmission tooth tube 321, thereby further increasing the stability of the transmission tooth tube 321 when rotating within the conveyor belt 314. By setting a reinforcing angle plate 5, which can cooperate with the positioning rod 311, the reinforcing angle plate 5 can provide auxiliary reinforcement at the connection between the positioning rod 311 and the air flotation machine body 1, thereby further increasing the stability of the connection between the positioning rod 311 and the air flotation machine body 1.

[0039] Specifically, such as Figure 6 As shown, an auxiliary rotating plate 6 is rotatably connected to the surface of the transmission gear tube 321, and the inner side of the auxiliary rotating plate 6 is in contact with the surface of the guide gear plate 313.

[0040] Specifically, such as Figure 6 As shown, an auxiliary guide plate 7 is snapped onto the surface of the collecting arc plate 322, and the auxiliary guide plate 7 is set in an arc shape.

[0041] In this embodiment: by setting an auxiliary rotating plate 6, which can cooperate with the transmission gear tube 321, the auxiliary rotating plate 6 can provide auxiliary limit to the movement of the transmission gear tube 321, further increasing the stability of the transmission gear tube 321 during movement. By setting an auxiliary guide plate 7, which can cooperate with the collecting arc plate 322, the collected oil and impurities can be further guided by the auxiliary guide plate 7, which can increase the stability of oil and impurity collection.

[0042] Working principle: First, the air flotation machine body 1 is powered on and started. When the air flotation machine body 1 generates oil and impurities during operation, the electric rotary rod assembly 312 will drive the conveyor belt 314 to reciprocate. Then, the conveyor belt 314 will drive the transmission tooth tube 321 to reciprocate. The transmission tooth tube 321 will rotate along the guide tooth plate 313, and drive the transmission tube 323 and the collecting arc plate 322 to rotate. The collecting arc plate 322 will collect the oil and impurities and transport them into the transmission tube 323. Then, the oil and impurities will move along the transmission tube 323 to the gravity rotary tube 324. Then, the guide spiral plate 325 will transport the oil and impurities to the filter plate 24 as the transmission tube 323 rotates. The oil will flow through the filter plate 24 into the oil storage box 21. The electric heating plate 22 will heat the oil. Then, the filter plate 24 will be removed from the positioning plate 23, and the collected oil and impurities will be recovered separately.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
