Description

Technical Field

[0001] The utility model relates to the technical field of oil-water separation, in particular to a cyclone oil-water separator. Background Art

[0002] In the process of oil extraction and processing, oily wastewater will be discharged. In the process of treating oily wastewater, it is necessary to separate the oil and water in the oily wastewater. The cyclone oil-water separator is a physical separation equipment, which is often used to separate oil and wastewater in oil-water mixed liquid. It is widely used in oil fields, chemical industry, electric power and other fields. It can effectively separate the oil from the wastewater to achieve the purpose of environmental protection and resource recovery. At the same time, it can also reduce production costs and improve production efficiency. The working principle of the cyclone oil-water separator is to use the centrifugal force generated by the liquid during the rotation process. The force separates the oil and water. Specifically, when the oil-water mixed liquid enters the cyclone oil-water separator, the oil will float on the water due to the different density of the liquid. At this time, the cyclone in the cyclone will rotate the liquid to form a vortex, so that the oil and water are separated at the center of the vortex. In the process of vortex formation, the liquid will generate centrifugal force when it rotates, so that the water with higher density moves to the outside of the vortex, while the oil with lower density is concentrated in the center of the vortex. In this way, the oil-mixed liquid will be separated along the flow direction of the vortex, and then discharged from the cyclone oil-water separator through the corresponding material discharge port.

[0003] The existing cyclone oil-water separator has a relatively viscous texture and is easy to stick to the discharge pipe. The oil is generally transported by water pumps. The water pump is prone to blockage, resulting in unstable oil discharge effect. The water pump structure is relatively complex, the probability of problems is high, and maintenance is troublesome. There are certain impurities in the oil mixture. The feed pipe of the existing cyclone oil-water separator lacks a filtering structure. After a long time, the internal pipe will be blocked. The cyclone oil-water separator needs to be disassembled for cleaning, which is very troublesome. Therefore, a cyclone oil-water separator is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a cyclone oil-water separator to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A cyclone oil-water separator comprises a cyclone oil-water separator, wherein an overflow pipe is provided at the top of the cyclone oil-water separator, a first flange is fixedly connected to the top of the overflow pipe, a second flange is fixedly connected to the top of the first flange by bolts, a connecting pipe is fixedly connected to the top of the second flange, a transmission pipe is fixedly connected to the end of the connecting pipe away from the second flange, a heating layer is fixedly connected to the inner side of the transmission pipe, a fixing plate is fixedly connected to the end of the transmission pipe away from the connecting pipe, a motor is fixedly connected to the outer side of the fixing plate, a rotating shaft passing through the rotating shaft is fixedly connected to the outer side of the rotating shaft, an auger is fixedly connected to the bottom end of the transmission pipe, and a feed pipe is fixedly connected to the outer side of the cyclone oil-water separator.

[0007] Preferably, the end of the feed pipe away from the cyclone oil-water separator is fixedly connected with a connecting sleeve, the inner side of the feed pipe is fixedly connected with a limiting block, and the inside of the feed pipe is slidably connected with a filter screen located on the left side of the limiting block.

[0008] Preferably, the filter screen is conical in shape, and the maximum diameter of the filter screen is consistent with the inner diameter of the feed pipe.

[0009] Preferably, the outer diameter of the auger is consistent with the inner diameter of the heating layer, and they fit together.

[0010] Preferably, the discharge pipe is connected through the heating layer and is arranged at the rightmost end of the transmission pipe and the heating layer.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, the overflow pipe, connecting pipe, transmission pipe, heating layer, fixed plate, motor, rotating shaft, auger and discharge pipe and other components are set, and the separated oil overflows into the transmission pipe through the overflow pipe and the connecting pipe by the cyclone oil-water separator, and the rotating shaft is driven by the motor to rotate, and the rotating shaft drives the auger to rotate, and the oil is stably transported and transmitted by the auger. The heating layer can heat the oil when the auger transmits the oil to prevent the oil from solidifying. Under the action of the auger, the oil can effectively prevent the pipeline from being blocked. Compared with water pump extraction, the auger is more stable, and the structure is simple and not easy to be damaged, and the maintenance is also simple. The oil finally enters the collection barrel through the discharge pipe, thereby solving the problem that the existing cyclone oil-water separator is easy to stick to the discharge pipeline due to its viscous texture. The oil transmission is generally extracted and transported by a water pump, and the water pump is easy to be blocked inside, resulting in unstable oil discharge effect. In addition, the water pump structure is relatively complex, the probability of problems is large, and the maintenance is troublesome.

[0013] 2. In the utility model, the feed pipe, connecting sleeve, limit block and filter screen and other components are provided, and the connecting sleeve is connected to the pipeline for transmitting the oil-water mixed liquid. The oil-water mixed liquid will first pass through the conical filter screen to filter out the particulate impurities in the oil-water mixed liquid to prevent clogging of the cyclone oil-water separator. The conical filter screen can filter the debris to the edge inside the feed pipe. Even if the debris accumulates, the filter screen will not block the oil-water mixed liquid and prevent it from passing. The limit block can block the filter screen and prevent it from being rushed into the cyclone oil-water separator. The connecting sleeve added at the feed pipe can facilitate the disassembly of the pipeline, and the removal of the filter screen for cleaning the debris is convenient, without the need to disassemble the cyclone oil-water separator as a whole, thereby solving the problem that the feed pipe of the existing cyclone oil-water separator lacks a filtering structure, and the internal pipeline will be blocked over time, and the cyclone oil-water separator needs to be disassembled for cleaning, which is very troublesome.

[0024] Working process: when the cyclone oil-water separator needs to be used, the whole device including the motor 10 is powered by an external power supply.

Compared with water pump extraction, the auger 12 is more stable, and the structure is simple and not easy to damage, and the maintenance is also simple. The oil finally enters the collection barrel through the discharge pipe 13.
