Description

Technical Field

[0001] The utility model relates to the technical field of oil-water separators, in particular to an oil-water separator with a filtering function. Background Art

[0002] In the process of oil production and processing, oil-water mixture is often produced, such as oily wastewater, oil pollutants, etc. Oil-water separation is mainly based on the density difference or chemical properties of water and oil, and uses the principle of gravity sedimentation or other physical and chemical reactions to separate oil and water. Before the oil-water separator separates the oil-water mixture, it is best to filter it to remove impurities in it to avoid the problem of impurities accumulating during long-term separation operations and causing blockage inside the separator. Most of the existing filtering devices are filter screens and are directly installed on the inside of the liquid inlet for preliminary filtering operations. They need to be disassembled and removed regularly to clean the impurities on them, which wastes energy. In addition, the cleaning time cannot be accurately judged due to the different impurity contents in the mixed liquid, resulting in untimely cleaning and inability to maintain a stable liquid inlet volume of the mixed liquid, affecting the efficiency of oil-water separation. Utility Model Content

[0003] The purpose of the utility model is to provide an oil-water separator with a filtering function, which does not need to be frequently disassembled to remove the filter and clean the impurities thereon, making cleaning more convenient and ensuring that the filter maintains an optimal flow state at all times, so that the mixed liquid can continuously and stably enter the separator body, thereby ensuring the high efficiency of oil-water separation.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an oil-water separator with filtering function, comprising a separator body, wherein the lower parts of the left and right sides of the separator body are equipped with water outlet pipes, and the bottom center of the separator body is equipped with an oil outlet pipe, the bottom of the oil outlet pipe is fixedly connected with a delivery pipeline, the delivery pipeline is arranged in the front-back direction, a cushion seat is arranged at the bottom of the delivery pipeline, a frame plate is symmetrically fixed on the top of the cushion seat, the top of the frame plate is fixedly connected to the separator body, a filter bin is fixedly connected at the top center of the separator body, a liquid inlet hopper is fixedly connected at the top center of the filter bin, a driving motor is arranged on the left side of the filter bin, a pad is arranged at the bottom of the driving motor, the right side of the pad is fixedly connected to the filter bin, and a slag discharge screw is fixedly connected to the right output end of the driving motor, and the slag discharge screw extends to the right into the interior of the filter bin and rotates with it The filter screen is connected at the bottom of the filter bin, and the filter screen is connected at the bottom of the filter bin to the filter screen, and the filter screen is connected at the bottom of the filter bin to the filter screen.

[0005] According to the oil-water separator with filtering function, the inner side of the liquid inlet bucket is covered with a layer of anti-corrosion slitting film to prevent the oil-water mixture from adhering to the inner wall of the liquid inlet bucket and causing corrosion.

[0006] According to the oil-water separator with filtering function, a filtrate port is provided at the bottom center of the slag discharge port, the top of the filtrate port is connected to the inside of the slag storage tank, and a valve is provided on the inner side of the bottom of the filtrate port. Before slag discharge, a small amount of oil and water squeezed into the slag discharge tank by the screw is filtered out and recovered.

[0007] According to the oil-water separator with filtering function, a liquid level meter is fixedly connected to the inner wall of the right upper inner side of the slag storage tank to quantitatively detect the temporary storage amount of impurities in the slag storage tank for convenient regular removal.

[0008] According to the oil-water separator with filtering function, a plurality of holes are evenly arranged on the left and right sides of the slag discharge screw rod, so that most of the oil and water can pass through the holes, and excessive oil and water are prevented from being squeezed out by the screw rod into the slag storage tank.

[0009] According to the oil-water separator with filtering function, an observation window is embedded and fixed at the center of the front side of the filtering chamber, so as to facilitate real-time and clear observation of the filtering state of the arc filter.

[0010] The above scheme has the following beneficial effects:

[0011] In the utility model, an arc filter screen and a slow flow cover are set up in the filter bin to block the impurities in the mixed liquid, and then the impurities are slowly discharged into the slag storage tank for temporary storage in cooperation with a slag discharge screw. There is no need to frequently disassemble and remove the filter screen and clean the impurities thereon, so the cleaning is more convenient and the filter screen can always be ensured to maintain the best flow state, so that the mixed liquid can continuously and stably enter the separator body, thereby ensuring the high efficiency of oil-water separation.
