Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a wastewater treatment tank with an oil adsorption filter membrane. Background Technology

[0002] In industrial production and daily life, wastewater discharge is often accompanied by a large amount of floating oil. If this floating oil is discharged directly without effective treatment, it will not only cause an oil film to cover the surface of the water body, hindering the exchange of oxygen between the water and the air, leading to the death of aquatic organisms due to lack of oxygen, but also cause continuous pollution to the ecological environment such as soil and groundwater, and will also affect the efficiency of subsequent wastewater treatment processes.

[0003] The utility model patent with announcement number CN223386012U discloses a heavy medium velocity sedimentation treatment device for coal mine wastewater, including a treatment tank. The treatment tank is provided with a coagulation chamber, a reaction chamber, a flocculation chamber and a sedimentation chamber. The inner walls on both sides of the treatment tank located at the flocculation chamber and the sedimentation chamber are provided with mounting grooves. Mounting shafts are rotatably installed in the two mounting grooves. A first gear is fixedly installed at one end of the two mounting shafts that rotatably extend outside the treatment tank.

[0004] Although this invention can adsorb suspended oil on the surface of coal mine wastewater through a rotating oil-absorbing sponge cylinder, and simultaneously squeeze the oil-absorbing sponge cylinder downwards by a rotating extrusion roller, causing the extruded suspended oil liquid to enter the oil guide slope of the oil discharge pipe through an arc-shaped mesh filter plate, and then be discharged to the outside through the outlet end of the oil discharge pipe by the inclined guide slope, thus achieving the effect of removing oil, the adsorption position is fixed and the adsorption height cannot be dynamically adjusted to adapt to changes in the floating oil layer under different working conditions, thereby affecting the overall treatment effect. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater treatment tank with an oil adsorption filter membrane to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wastewater treatment tank equipped with an oil-floating adsorption filter membrane, comprising the wastewater treatment tank and further including:

[0008] A lifting mechanism for controlling the adsorption height of floating oil includes two vertical plates fixed to the top surface of the wastewater treatment tank, a horizontal plate fixed between the top ends of the two vertical plates, a hydraulic cylinder fixed at the center of the bottom surface of the horizontal plate, and an installation plate fixed at the bottom end of the extension end of the hydraulic cylinder.

[0009] An adsorption mechanism for rotating and adsorbing floating oil includes a motor fixed at the center of the bottom surface of the mounting plate. Several connecting rods are regularly fixed on the outer wall of the motor output shaft. An installation frame is fixed at the other end of the connecting rods. The installation frame is inclined. A rectangular frame is fixed inside the installation frame. An adsorption filter membrane is fixed inside the rectangular frame.

[0010] Preferably, an inlet pipe is installed on the side wall of the wastewater treatment tank near the top, and an outlet pipe is installed in the middle of the bottom wall of the wastewater treatment tank. Both the inlet pipe and the outlet pipe are equipped with valves.

[0011] This feature includes inlet and outlet pipes with valves at the top and bottom of the side wall of the wastewater treatment tank, enabling flexible control over the entire wastewater treatment process.

[0012] Preferably, each of the four corners of the mounting frame is provided with a movable block, and a post is fixed to the center of the side of the movable block near the mounting frame.

[0013] Preferably, the rectangular frame has mating holes at each of its four corners that correspond to the positions of the inserts and are of the same size. The inserts pass through the mounting frame and are inserted into the corresponding mating holes.

[0014] Preferably, limit blocks are fixed at the upper and lower side edges of the mounting frame, and a control rod is rotatably connected between the two limit blocks. The length of the control rod is greater than the distance between the two limit blocks, and a stop block is fixed at both ends of the control rod.

[0015] Preferably, limit posts are fixed at all four corners of the mounting frame, and the other end of each limit post is also fixed with a stop block. The limit posts are slidably connected to the adjacent movable blocks.

[0016] Preferably, both ends of the control rod are threaded ends, the thread directions of the two ends of the control rod are opposite, and the two ends of the control rod are respectively threadedly connected to the movable blocks on both sides.

[0017] Preferably, a collar is fitted on the middle of the outer side wall of the control rod, and the outer side wall of the collar is roughened.

[0018] These six settings, through precise matching of the insertion post and docking hole, and trajectory constraints of the limiting block and limiting post, construct multiple positioning and anti-deviation protections. This effectively resists the centrifugal force generated by the motor rotation, ensuring the stable position of the rectangular frame and adsorption filter membrane during operation and preventing them from falling off. This avoids affecting the oil adsorption effect due to structural loosening, while protecting components from misalignment damage, thus improving equipment operation safety and adsorption reliability. Through the synchronous drive design of the control rod's reverse thread and the convenient operation characteristics of the roughened collar, operators can quickly insert and remove the insertion post and docking hole by rotating the collar without the need for complex tools, efficiently completing the replacement of the adsorption filter membrane. This significantly shortens equipment downtime for maintenance, reduces manual operation intensity and overall maintenance costs, and balances equipment operating efficiency with long-term ease of use.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model, by setting up a lifting mechanism composed of a vertical plate, a horizontal plate, a hydraulic cylinder and a mounting plate, can drive the mounting plate and the adsorption mechanism below to move up and down as a whole by means of the extension and retraction action of the hydraulic cylinder. It can accurately adjust the contact height between the adsorption filter membrane and the oil layer according to the actual height and thickness of the oil layer in the wastewater treatment tank, thereby improving the targeting of oil removal and the utilization rate of the adsorption membrane.

[0021] 2. This utility model features a quick-release structure consisting of a movable block, a plug, a control rod, and a limiting post. Rotating the collar with a roughened outer wall drives the control rod to rotate. Since the two ends of the control rod have reverse threads and are threadedly connected to the movable blocks on both sides, rotation can drive the movable blocks on both sides to move closer or further away from the limiting post simultaneously. This enables quick insertion and removal of the plug and the rectangular frame docking hole, facilitating the replacement of the rectangular frame and the adsorption filter membrane, shortening downtime for maintenance, and reducing manual operation intensity and maintenance costs.

[0030] The technical solutions of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] Please see Figures 1-4 The present invention provides the following technical solution:

[0032] A wastewater treatment tank equipped with an oil-floating adsorption filter membrane, comprising wastewater treatment tank 100, and further comprising:

[0033] A lifting mechanism 200 for controlling the height of oil adsorption includes two vertical plates 201 fixed to the top surface of the wastewater treatment tank 100, a horizontal plate 202 fixed between the top ends of the two vertical plates 201, a hydraulic cylinder 203 fixed at the center of the bottom surface of the horizontal plate 202, and an installation plate 204 fixed at the bottom end of the extension and retraction end of the hydraulic cylinder 203. The lifting mechanism 200 can drive the installation plate 204 and the adsorption mechanism 300 below it to move up and down as a whole through the extension and retraction action of the hydraulic cylinder 203. It can accurately adjust the contact depth between the adsorption filter membrane 305 and the oil layer according to the actual height of the oil layer in the wastewater treatment tank 100, so as to avoid the adsorption filter membrane 305 being completely immersed in the water, resulting in ineffective filtration, or detaching from the oil layer, resulting in adsorption leakage, thus improving the targeting of oil removal.

[0034] An adsorption mechanism 300 for rotating adsorption of floating oil includes a motor 301 fixed at the center of the bottom surface of a mounting plate 204. Several connecting rods 302 are regularly fixed on the outer wall of the output shaft of the motor 301. An mounting frame 303 is fixed at the other end of the connecting rods 302. The mounting frame 303 is inclined and a rectangular frame 304 is fixed inside the mounting frame 303. An adsorption filter membrane 305 is fixed inside the rectangular frame 304. When the motor 301 of the adsorption mechanism 300 drives the output shaft to rotate, it will drive the multiple inclined mounting frames 303 to rotate synchronously through the connecting rods 302, so that the adsorption filter membrane 305 makes a circular motion on the surface of the floating oil layer, expanding the adsorption coverage area. At the same time, the inclined mounting frame 303 can reduce water flow resistance, improve adsorption efficiency, and prevent floating oil from accumulating in a localized area.

[0035] In this embodiment, please refer to Figure 1 The wastewater treatment tank 100 has an inlet pipe 101 installed near the top of its side wall, and an outlet pipe 102 installed in the middle of its bottom wall. Both the inlet pipe 101 and the outlet pipe 102 are equipped with valves 103. The valves 103 can flexibly control the inlet flow rate and the outlet rhythm. For example, when the floating oil in the tank is not completely treated, the valve 103 of the outlet pipe 102 can be closed, and the outlet can be opened again after the adsorption and filtration are completed. At the same time, the inlet speed can be adjusted by the valve 103 of the inlet pipe 101 to match the treatment efficiency of the adsorption mechanism 300, so as to avoid wastewater overflow or insufficient treatment.

[0036] In this embodiment, please refer to Figures 1-4 Movable blocks 309 are provided at each of the four corners of the mounting frame 303. An insert post 311 is fixed at the center of the side of the movable block 309 near the mounting frame 303. The insert post 311 serves as a connecting carrier and can directly engage with the docking hole of the rectangular frame 304 to provide precise positioning support for the rectangular frame 304, preventing the rectangular frame 304 from shaking inside the mounting frame 303, thereby ensuring the adsorption stability of the adsorption filter membrane 305.

[0037] Specifically, the rectangular frame 304 has mating holes at its four corners that correspond to the positions and sizes of the insert posts 311. The insert posts 311 pass through the mounting frame 303 and are inserted into the corresponding mating holes. This structure, where the insert posts 311 pass through the mounting frame 303 and are inserted into the mating holes, forms a double positioning system. This prevents the rectangular frame 304 from falling off due to centrifugal force during the rotation of the adsorption mechanism 300, thus improving structural safety.

[0038] Furthermore, limit blocks 306 are fixed at the upper and lower edges of the mounting frame 303. A control rod 307 is rotatably connected between the two limit blocks 306. The length of the control rod 307 is greater than the distance between the two limit blocks 306. Stop blocks 312 are fixed at both ends of the control rod 307. The limit blocks 306 provide stable rotational support for the control rod 307, preventing radial swaying when the control rod 307 rotates and ensuring the smooth movement of the subsequent movable block 309.

[0039] In addition, limit posts 310 are fixed at the four corners of the mounting frame 303, and a stop block 312 is fixed at the other end of the limit post 310. The limit post 310 is slidably connected to the adjacent movable block 309. The limit post 310 provides a linear guide for the movable block 309 to prevent the movable block 309 from shifting when it rotates with the control rod 307, and ensures that the insertion post 311 can be accurately aligned with the docking hole of the rectangular frame 304, so as to avoid damage to the insertion post 311 due to offset.

[0040] It is worth noting that both ends of the control lever 307 are threaded ends, and the thread directions of the two ends of the control lever 307 are opposite. The two ends of the control lever 307 are threadedly connected to the movable blocks 309 on both sides. Simply rotating the control lever 307 will make the movable blocks 309 on both sides move synchronously, while ensuring that the moving distance of the movable blocks 309 on both sides is completely consistent, thus avoiding the force imbalance of the insertion post 311 due to uneven movement on one side.

[0041] It is worth noting that a collar 308 is fitted in the middle of the outer side wall of the control lever 307. The outer side wall of the collar 308 is roughened, such as by knurling, grooving or pasting anti-slip texture, to increase the friction coefficient of the outer side wall of the collar 308.

[0042] Finally, it should be noted that the hydraulic cylinder 203 and motor 301 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0043] When using the wastewater treatment tank with floating oil adsorption filter membrane of this utility model, open the valve 103 on the inlet pipe 101 and inject the wastewater containing floating oil to be treated into the wastewater treatment tank 100 through the inlet pipe 101.

[0044] After standing for a period of time, once the floating oil in the wastewater treatment tank 100 has completely floated to the surface, observe the height and thickness of the floating oil layer.

[0045] Start the hydraulic cylinder 203 in the lifting mechanism 200. The telescopic end of the hydraulic cylinder 203 extends downward, driving the mounting plate 204 fixed to the telescopic end to descend synchronously. During the descent of the mounting plate 204, it will move down together with the adsorption mechanism 300 fixed at the bottom. When the adsorption filter membrane 305 in the adsorption mechanism 300 descends to the appropriate position, the action of the hydraulic cylinder 203 is stopped, and the adsorption height is precisely adjusted.

[0046] When the motor 301 in the adsorption mechanism 300 is started, the output shaft of the motor 301 begins to rotate, driving several connecting rods 302 fixed on the outer wall of the output shaft to rotate synchronously. When the connecting rods 302 rotate, they will cause the mounting frame 303 fixed at the other end, the rectangular frame 304 inside the mounting frame 303, and the adsorption filter membrane 305 inside the rectangular frame 304 to move in a circular motion. The inclined mounting frame 303 drives the adsorption filter membrane 305 to rotate on the surface of the floating oil layer. The adsorption filter membrane 305 adsorbs the floating oil through its hydrophobic and oleophilic properties. Because the adsorption filter membrane 305 moves in a circular motion, it can cover the entire water surface in the wastewater treatment tank 100, avoiding floating oil residue. The adsorption time is set according to the floating oil concentration.

[0047] When the adsorption filter membrane 305 is saturated, first turn off the motor 301, then start the hydraulic cylinder 203, so that the telescopic end of the hydraulic cylinder 203 retracts upward, driving the mounting plate 204 and the adsorption mechanism 300 to rise to a safe position above the wastewater treatment tank 100.

[0048] The operator holds the collar 308 on the outer wall of the control rod 307 in the adsorption mechanism 300 and rotates the collar 308, causing the control rod 307, which is fixed to the collar 308, to rotate between the two limit blocks 306. Since the two ends of the control rod 307 are reverse-threaded and respectively threaded to the movable blocks 309 on both sides, the rotation will drive the movable blocks 309 on both sides to move away synchronously along the limit post 310. During the movement of the movable blocks 309 away, the insertion post 311 fixed on the side near the mounting frame 303 will gradually disengage from the mating holes at the corners of the rectangular frame 304. After all the insertion posts 311 are completely disengaged... After disengaging from the docking hole, remove the rectangular frame 304 and the internal adsorption filter membrane 305, and replace them with a new rectangular frame 304 and adsorption filter membrane 305. Place the new rectangular frame 304 into the mounting frame 303, ensuring that the docking holes at the corners of the rectangular frame 304 are aligned with the insertion posts 311 of the movable block 309. Rotate the collar 308 in the opposite direction to drive the control rod 307 to rotate in the opposite direction, so that the movable blocks 309 on both sides move closer to each other along the limiting post 310. After the insertion post 311 passes through the mounting frame 303, it is inserted into the docking hole of the rectangular frame 304, thus completing the fixation of the rectangular frame 304 and the adsorption filter membrane 305.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
