Description

Technical Field

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

[0002] The oil-water separator in the prior art is generally provided with a separation tank, a water outlet pipe and an oil outlet pipe. The oil outlet pipe is located above the water outlet pipe. Since the oil floats on the water surface, the oil is discharged from the oil outlet pipe and the water is discharged from the water outlet pipe.

[0003] However, the existing oil-water separators not only have slow filtering efficiency and are difficult to clean the filter residue, but also during continuous operation, the oil-water mixture is continuously discharged into the separation tank, causing waves on the liquid surface, causing part of the water in the liquid to be discharged from the oil outlet pipe along with the oil, so that the separated oil contains a certain amount of water, resulting in poor oil-water separation effect. Utility Model Content

[0004] The utility model aims to provide a novel oil-water separator, which can not only filter quickly and conveniently process filter residues, but also obtain oil with higher purity than traditional separation.

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

[0006] A novel oil-water separator comprises a separation tank, a filter residue frame, a water outlet pipe, an oil outlet pipe, an oil scraper and a motor; the filter residue frame is arranged at the upper end of one side of the separation tank; the filter residue frame is provided with filter holes, and the residue in the oil-water mixture is filtered through the filter residue frame; the water outlet pipe is arranged at the lower end of the separation tank away from the filter residue frame, and a water outlet valve is arranged on the water outlet pipe; the oil outlet pipe is rotatably connected to one side of the upper end of the separation tank; the motor is fixed at the upper end of the separation tank; the inner end of the oil outlet pipe is fixedly connected to the output shaft of the motor, and the outer end of the oil outlet pipe passes out from the separation tank; the oil scraper is fixed to the outer wall of the oil outlet pipe in the separation tank; an oil delivery cavity is arranged in the oil scraper, and a plurality of oil inlet holes are arranged on one side of the oil scraper; a water removal layer for intercepting water molecules is arranged in the oil inlet hole; the oil inlet hole is connected with the oil delivery cavity, and the oil delivery cavity is connected with the oil outlet pipe, and the oil scraper is driven by the motor to rotate to discharge oil molecules from the oil inlet hole, the oil delivery cavity and the oil outlet pipe.

[0007] Furthermore, the inner cavity of the oil outlet pipe is in a truncated cone shape, and the aperture of the inner cavity of the oil outlet pipe gradually increases from the inside to the outside.

[0008] Furthermore, overlapping edges are fixed on both sides of the filter residue frame; and the overlapping edges are overlapped on the upper edge of the separation tank.

[0009] Furthermore, a handle is fixed on the overlapped edge.

[0010] Furthermore, the material of the water removal layer is a material that only allows oil molecules to pass through.

[0011] Furthermore, a blocking plate is fixed on one side of the separation tank close to the water outlet pipe; a downward flow opening is provided between the lower end of the blocking plate and the bottom surface of the separation tank; and the upper end height of the blocking plate is less than the installation height of the scraper plate.

[0012] Furthermore, a guide plate is fixed on the bottom surface of the separation tank on the side of the lower flow opening away from the water outlet pipe; the height of the upper end of the guide plate is greater than the lower flow opening.

[0013] Furthermore, a cover plate is provided on the separation tank on the side of the filter residue frame.

[0014] After adopting the above technical solution, the utility model has the following beneficial effects:

[0015] 1. The oil scraper of the utility model is provided with an oil delivery cavity inside, and a plurality of oil inlet holes are provided on one side of the oil scraper, and a water removal layer that only allows oil molecules to pass through is provided in the oil inlet holes; under the action of the oil scraper, the oil droplets of the oil-water mixture can quickly and directionally pass through the oil inlet holes to reach the inside of the oil scraper; when the oil scraper slowly rotates from the lower end to the upper end, the inclination direction inside the oil delivery cavity changes from obliquely upward to obliquely downward, so that the oil droplets pass through the oil delivery cavity and enter the inner cavity of the oil outlet pipe; when the oil droplets enter the inner cavity of the oil outlet pipe, due to the oil outlet pipe The inner cavity is truncated cone-shaped, and the aperture of the inner cavity of the oil outlet pipe gradually increases from the inside to the outside, so that the oil droplets falling into the inner cavity move directionally from the inside to the outside; this oil removal method solves the problem that the oil-water mixture is continuously discharged into the separation tank, causing wave fluctuations on the liquid surface in the separation tank, resulting in low purity of the separated oil; in addition, a cover plate is provided on the separation tank above the scraper plate and the scraper plate rotates slowly, so that no large beating force is generated when entering the liquid surface, effectively avoiding the splashing of oil droplets and reducing the noise generated during the operation of the instrument.

[0016] 2. The filter residue frame arranged in the utility model is provided with filter holes on the front and rear side walls and the bottom, which can effectively filter the residue in the oil-water mixture; when the filter residue is deposited under the action of gravity, the filter holes on the side walls of the filter residue frame can still allow the liquid to flow rapidly; in addition, overlapping edges are fixed on both sides of the filter residue frame; the overlapping edges are arranged on the upper edge of the separation tank, and handles are fixed on the overlapping edges, which can facilitate the disassembly and cleaning of the filter residue; the problems of slow filtering efficiency, difficult cleaning of filter residue and cumbersome disassembly of the filtering device of the traditional oil-water separator are solved, and the work efficiency is improved.

[0017] 3. In the utility model, a baffle plate is provided on the side of the separation tank close to the water outlet pipe, a downward flow port is provided between the lower part of the baffle plate and the bottom surface of the separation tank, and a drainage plate is provided on the bottom surface of the separation tank on the side of the downward flow port away from the water outlet pipe. Since the density of oil is smaller than that of water, the oil in the oil-water mixture floats upward; under the action of the drainage plate, the oil in the oil-water mixture has sufficient time to float upward, thereby improving the effect of oil-water separation; in addition, the upper end height of the baffle plate is less than the installation height of the oil scraper plate, so that the oil molecules entering the downward flow port when the instrument is initially started can return to the oil layer and be discharged through the oil scraper plate.

[0018] 4. The utility model is provided with a water outlet valve on the water outlet pipe. When the instrument is just started, the water outlet valve is in a closed state, which can prevent the oil molecules initially entering the lower flow port from being directly discharged from the water outlet pipe; after the water layer height reaches an appropriate height, when the oil layer can be discharged through the oil scraper, the water outlet valve is opened to balance the amount of liquid flowing out of the water outlet pipe and the oil outlet pipe with the amount of liquid entering the separation tank, so that the utility model can work continuously.
