Description

Technical Field

[0001] The utility model relates to the technical field of oil-water separators, in particular to an anti-solidification oil-water separator. Background Technique

[0002] The working principle of the oil-water separator is mainly based on the density difference between water and fuel, and the gravity sedimentation principle is used to remove impurities and water. When the oily sewage enters the oil-water separator through the diffusion nozzle, large oil droplets will float to the top of the oil collection chamber, while water will sink to the bottom, thus realizing the separation of oil and water. Oil-water separators are widely used in various scenarios where oily wastewater needs to be treated, such as kitchen catering, petrochemical industry, and machining industry. Especially in the field of kitchen catering, oil-water separators are widely used in restaurants, fast food restaurants, chain stores and other places to treat the oily wastewater generated during the catering process.

[0003] The existing oil-water separator has poor continuity during use and cannot work continuously, resulting in low efficiency;

[0004] The existing patent (Publication No.: CN219174236U) discloses an oil-water separator, which includes a first separation tank, a flow stabilizing plate, a water inlet, a connecting pipe and a first oil outlet. By discharging the oil-water mixed liquid into the device through the water inlet pipe, the oil-water separation can be carried out, and the separated oil can be continuously discharged from the oil outlet, so that the device can work continuously and the separation effect is better, which is beneficial to improving the oil-water separation efficiency of the device.

[0005] In view of the above problems, although the solution given by the existing patent can carry out oil-water separation by discharging into the device through the water inlet pipe to achieve the effect of continuous operation, when it is in use, if the oil-water temperature is too low, the oil and water will solidify, resulting in poor oil-water separation effect. Summary of the Invention

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides a technical solution:

[0027] Please refer to Figures 1 to 4 , an anti-solidification oil-water separator, including a separator housing 1, one end of the separator housing 1 is communicated with a water inlet pipe 2, and the right side of the separator housing 1 is connected with a circulation mechanism for circulating sewage;

[0028] The circulation mechanism includes a circulation pipe 3, which is connected to the right side of the separator housing 1. The end of the circulation pipe 3 is connected to a heating element 31. One end of the heating element 31 is connected to a connecting pipe 32, and the end of the connecting pipe 32 is connected to a delivery pump 33 that communicates with the separator housing 1. Two heating pipes 34 are fixed inside the heating element 31. A filter screen 35 is arranged below the two heating pipes 34. Both ends of the filter screen 35 are fixed with clamping blocks 36, and the outer surfaces of the clamping blocks 36 are inserted into clamping grooves 37 opened on the inner wall of the heating element 31. One side of the filter screen 35 is fixed with a movable plate 38, and the movable plate 38 is movably connected to the heating element 31. A filtering element 4 is installed inside the separator housing 1. A fixing bolt 5 that is threadedly connected to the separator housing 1 is installed on the upper surface of the filtering element 4. A filter plate 6 is fixed to the lower end inside the separator housing 1.

[0029] By adopting the above technical solution, before using the anti-solidification oil-water separator, first place the separator housing 1 in a suitable position. When in use, connect the water inlet pipe 2 to an external oil-water pipe, so that external oil and water enter the inside of the separator housing 1. The oil and water first pass through the filtering element 4 for filtration, thereby reducing the impurities in the oil and water. Then it flows downward and is filtered again by the filter plate 6, and then enters the separation tank 7 for separation. The partition plate 8 can play a role in separation, so that large oil droplets will float to the top, while water will sink to the bottom, thus realizing the separation of oil and water. By opening the oil discharge pipe 10, the separated oil can be discharged to the outside for collection, and water flows out of the outside by opening the drain pipe 9. When the temperature of the oil and water is too low, the drain pipe 9 can be closed. With the cooperation of the circulation pipe 3, water can flow into the heating element 31. Through the filter screen 35, impurities in the water can be filtered. The set heating pipes 34 are started to heat the water. At this time, the set delivery pump 33 is started to pump out the water in the heating element 31. Through the connecting pipe 32, the water flows into the separator housing 1 again and circulates through the filtering element 4 again. The water with heat will heat the oil and water, thereby avoiding the solidification of the oil and water and ensuring the separation effect of the oil-water separator.

[0030] Specifically, as Figures 1 - 4 shown, a separation tank 7 is opened inside the separator housing 1. A partition plate 8 fixed to the separator housing 1 is arranged on the right side of the separation tank 7. A drain pipe 9 is communicated with the outer surface of the separator housing 1. An oil discharge pipe 10 communicated with the separation tank 7 is communicated with the outer wall of the separator housing 1.

[0031] By adopting the above technical solution, after use, the fixing bolt 5 can be unscrewed to release the fixation of the filter element 4, so that the filter element 4 can be disassembled, and the blocked impurities can be cleaned conveniently. Through the provided block 36 and the slot 37, the movable plate 38 can be pulled to pull the filter net 35 out of the heating element 31, further facilitating cleaning.

[0032] Working principle: connect the water inlet pipe 2 and the external oil-water pipe, the oil and water are filtered through the filter element 4, filtered again through the filter plate 6, and enter the separation tank 7 for separation, open the oil drain pipe 10, so that the separated oil can be discharged to the outside for collection, and the water is opened by opening the drain pipe 9 so that the water flows out, close the drain pipe 9, and with the cooperation of the circulation pipe 3, the water can flow into the heating element 31, and the impurities in the water are filtered through the filter net 35. The heating pipe 34 heats the water, and the delivery pump 33 draws out the water in the heating element 31, and the water flows into the separator housing 1 again through the connecting pipe 32, and circulates again through the filter element 4. The water with heat will heat the oil and water, thereby preventing the oil and water from solidifying, unscrew the fixing bolts 5, and release the fixation of the filter element 4, so that the filter element 4 can be disassembled, and the blocked impurities can be cleaned conveniently.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
