Description

Technical Field

[0001] This utility model relates to the technical field of impurity separation devices, specifically an impurity separation device for oily wastewater. Background Technology

[0002] Wastewater impurity separation devices are mainly used to remove suspended solids and solid impurities from wastewater, ensuring the efficiency of subsequent treatment and water quality safety. They are primarily designed for wastewater containing a mixture of high levels of oil and solid impurities.

[0003] For example, announcement number CN212669276U (titled "An Oil-Water Separation Device for Oily Wastewater") includes a wastewater tank for holding oily wastewater, a clear water tank for holding the separated water, and an oil storage tank for holding the separated oil. It also includes an inlet pipe, an outlet pipe, an oil outlet pipe, a rotating drum, and a motor for driving the rotating drum. The rotating drum has multiple mesh openings on its side wall, multiple layers of oil filter felt inside, an oil receiving tank outside the rotating drum, and a water receiving container inside the oil receiving tank. The water receiving container is located below the rotating drum, and a through hole is provided at the bottom of the rotating drum. One end of the inlet pipe is connected to the wastewater tank, and the other end passes through... The wall of the oil receiving tank extends into the rotating drum. The upper end of the water outlet pipe is connected to the water receiving container, and the lower end of the water outlet pipe extends into the clear water tank. One end of the oil outlet pipe is connected to the oil receiving tank, and the other end of the oil outlet pipe extends into the oil storage tank. By setting a rotating drum inside the oil receiving tank, multiple mesh holes are set on the side wall of the rotating drum, and multiple layers of oil filter felt are set inside the rotating drum. An oil receiving tank is set outside the rotating drum, and a water receiving container is set below the rotating drum. When the rotating drum rotates, the oil entering the rotating drum can be filtered through the oil filter felt and fly out from the mesh holes on the side wall of the rotating drum into the oil receiving tank. This can largely separate oil and water in oily wastewater, reduce the treatment cost of oily wastewater, and reduce environmental pollution.

[0004] The aforementioned impurity separation device separates oil and water in wastewater through an oil filtration mechanism. However, oil filtration alone cannot effectively remove impurities from the water, and the oil-water separation effect is poor, which affects the treatment effect of oily wastewater. Therefore, we provide an oily wastewater impurity separation device. Utility Model Content

[0005] The purpose of this utility model is to provide an oily wastewater impurity separation device to solve the problem mentioned in the background art that the existing impurity separation device separates oil and water in wastewater through the oil filtration mechanism, but oil filtration alone cannot effectively remove impurities in the water, and the oil-water separation effect is poor, which affects the treatment effect of oily wastewater.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an oil-water wastewater impurity separation device, comprising an oil-water separation cylinder, a support frame sleeved on the outside of the oil-water separation cylinder, a flocculation tank welded on one side of the outer wall of the support frame, an outlet valve pipe above the flocculation tank, and the outlet valve pipe communicating with the inside of the oil-water separation cylinder. Also includes: A cyclone separator is located at the center of the oil-water separator, and water outlet holes are arranged at equal intervals on the outer wall of the cyclone separator. A gear ring seat is welded to the top edge of the cyclone separator, and a servo motor is installed on one side of the gear ring seat. A drive gear is welded to the output shaft of the servo motor, and the drive gear meshes with the gear ring seat for transmission. A stirring shaft is installed inside the flocculation tank, and a drive motor is fixed to one end of the flocculation tank by screws. The output shaft of the drive motor is connected to the stirring shaft via a coupling. An oil outlet valve pipe is connected to the outer wall at the top of the oil-water separator, and a drain valve pipe is connected to the bottom of the oil-water separator.

[0007] Preferably, a drain valve pipe is connected to the bottom of the flocculation tank, and a microporous filter screen is provided at the starting end of the drain valve pipe. The frame of the microporous filter screen is fixedly connected to the flocculation tank by screws.

[0008] Preferably, a suspension frame is welded to the top of the servo motor, and a mounting rod is welded between the suspension frame and the oil-water separator.

[0009] Preferably, the inside of the cyclone drum is provided with a water inlet filter screen, which is fixedly connected to the cyclone drum by screws.

[0010] Preferably, the cyclone separator is externally fitted with a bearing housing, and three connecting rods are welded between the bearing housing and the oil-water separator.

[0011] Preferably, a limiting ring is provided below the bearing housing, and the limiting ring and the cyclone tube are an integral structure, with the size of the limiting ring being larger than the diameter of the bearing housing.

[0012] Preferably, the oil-water separator has a conical structure, and the support frame and the oil-water separator are an integral structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a servo motor to drive a drive gear, which in turn drives a meshing gear ring seat, which in turn drives a cyclone drum to rotate synchronously. The centrifugal force generated by the rotation forces the oily wastewater out through the outlet. The oil phase, due to its lower density, is thrown outwards and accumulates at the top before being discharged. The water phase flows out along the lower hole in the wall. The oil outlet valve is opened to discharge the oil phase, and the water outlet valve is opened to discharge the water phase. After entering the flocculation tank, flocculant is added, and the drive motor drives the stirring shaft to rotate, causing colloidal particles in the water phase to aggregate and form flocs, promoting sedimentation and separation. Finally, the drain valve is opened to discharge the separated water. This further improves the purification effect on wastewater after oil-water separation, overcoming the problem that existing impurity separation devices separate oil and water in wastewater through an oil filtration mechanism, but oil filtration alone cannot effectively remove impurities from the water, and the oil-water separation effect is poor, affecting the treatment effect of oily wastewater.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figure 1-4 An embodiment of this utility model is provided: an oil-containing wastewater impurity separation device, including an oil-water separation cylinder 1, a support frame 2 is sleeved on the outside of the oil-water separation cylinder 1, a flocculation tank 12 is welded on one side of the outer wall of the support frame 2, and an outlet valve pipe 11 is provided above the flocculation tank 12, and the outlet valve pipe 11 is connected to the inside of the oil-water separation cylinder 1. Also includes: The cyclone separator 4 is located at the center of the oil-water separator 1, and water outlet holes 20 are arranged at equal intervals on the outer wall of the cyclone separator 4. A gear ring seat 5 is welded to the top edge of the cyclone separator 4. A servo motor 8 is installed on one side of the gear ring seat 5. A drive gear 9 is welded to the output shaft of the servo motor 8. The drive gear 9 meshes with the gear ring seat 5 for transmission. A stirring shaft 14 is installed inside the flocculation tank 12, and a drive motor 13 is fixedly installed at one end of the flocculation tank 12 by screws.

The oil outlet valve pipe 3 is connected to the outer wall of the top of the oil-water separator 1, and the bottom of the oil-water separator 1 is connected to the drain valve pipe 16.

[0017] In use, oily wastewater is injected into the cyclone separator 4, and the servo motor 8 drives the drive gear 9 to rotate. The drive gear 9 rotates, which in turn drives the gear ring seat 5 to rotate, thus driving the cyclone separator 4 to rotate synchronously. With the help of the centrifugal force generated by the rotation, the oily wastewater is thrown out through the water outlet 20. The oil phase, due to its low density, is thrown to the outside and accumulates at the top for discharge. The water phase flows out along the lower hole of the device wall. The oil phase is discharged by opening the oil outlet valve pipe 3, and the water phase is discharged by opening the water outlet valve pipe 11. After the water phase enters the flocculation tank 12, flocculant is added, and the stirring shaft 14 is driven to rotate by the drive motor 13, which causes the colloidal particles in the water phase to aggregate and form flocs, promoting sedimentation and separation. Finally, the drain valve pipe 15 is opened to discharge the water after sedimentation and separation. After oil-water separation, the purification effect on wastewater is further improved.

The suspension bracket 7 welded to the top of the servo motor 8 serves to support the servo motor 8. Please refer to [link / reference]. Figure 1 The cyclone separator 4 is equipped with an inlet filter screen 6, which is fixedly connected to the cyclone separator 4 by screws. The inlet filter screen 6 inside the cyclone separator 4 serves as a preliminary filter for the oily wastewater during injection. Please refer to [link / reference].
