DETAILED DESCRIPTION

[0038] See also Figure 1-Figure 7In an embodiment of the present invention, an oil-water separator includes an oil-water tank 3, one side of the oil-water tank 3 is provided with an oil outlet 31, the oil outlet 31 is set through the side wall of the oil-water tank 3, the oil outlet 31 is connected and arranged at the upper part of the oil-water tank 3, and a guide plate with a downwardly inclined end is arranged outside the opening of the oil outlet 31, because the density is small, the oil in the kitchen waste will float on the upper layer and can flow out through the oil outlet 31; the bottom of the oil-water tank 3 is inclined, and a second sewage pipe 33 is connected and arranged on the lower side of the bottom of the oil-water tank 3, and a valve is arranged at the connection between the second sewage pipe 33 and the first sewage pipe 32. A first sewage pipe 32 is set through the upper side of the bottom of the oil-water tank 3, and one end of the second sewage pipe 33 located below the oil-water tank 3 is connected to the side of the first sewage pipe 32 located below the oil-water tank 3, and the upper end of the first sewage pipe 32 is equipped with an oil outlet position regulator 34 that can move vertically relative to the first sewage pipe 32. The oil-water tank 3 is provided with a heating element, and the preferred heating element can be an external heating plate used for the heating device, which can prevent dry burning and is not easy to be damaged. After power is turned on, the oil-water tank 3 can be heated. A mounting frame 1 is provided above the oil-water tank 3, and a leakage collecting pipe 16 opposite to the oil-water tank is provided through the bottom of the mounting frame 1, and a filter bucket 2 is installed on the mounting frame 1.

[0039] To use, follow these steps:

[0040] 1. Close the valve connecting the second sewage pipe 33 to the first sewage pipe 32. At this time, the liquid in the oil-water tank 3 can only flow out from the first sewage pipe 32 through the oil outlet position regulator 34. First, add a large amount of clean water to the oil-water tank 3 until clean water flows out of the oil outlet 31.

[0041] 2. After adding clean water, start heating with electricity. It can be used when heated to 40-70 degrees Celsius. This process generally takes 1-2 hours. Slight heating can assist in the rapid separation of oil and water. Heat before adding oily sewage. Otherwise, oil smoke will appear when heating oil. When the new equipment is heated for the first time, the heating plate will have slight smoke, which is normal. The reason is that the outer plate is stained with a little oil when it is processed on the machine tool. It will disappear after heating for a period of time. The input voltage of the heating element in the device is single-phase handle ring 220V and power 800W. The maximum adjustable temperature of the heating element is 80 degrees Celsius.

[0042] 3. According to the amount of oil in the liquid to be separated in the oil-water tank 3, the height of the oil outlet position regulator 34 in the oil-water tank 3 can be adjusted. If there is more oil than water in the tank, the height of the oil outlet position regulator 34 can be appropriately increased; if there is more water than oil in the tank, the height of the oil outlet position regulator 34 can be appropriately lowered; the higher the oil outlet position regulator 34 is, the faster the oil will flow out. When the oil content is small, the oil outlet position regulator 34 should not be too high, otherwise water will easily flow out of the oil outlet 31 simultaneously. The function of the oil outlet position regulator 34 is to adjust the height of the interface between oil and water. When the height of water exceeds the oil outlet position regulator 34, it can pass through the oil outlet position regulator 34 and be discharged from the first sewage pipe 32.

[0043] 4. After the oil and water are separated, open the valve of the second drain pipe 33 connected to the first drain pipe 32. At this time, the liquid in the oil-water tank 3 can be discharged through the second drain pipe 33. The heating element needs to be turned off 20 minutes in advance for cleaning. After all the liquid in the oil-water tank 3 is drained, cleaning and maintenance can be carried out. After maintenance, fill it with water and reuse it.

[0044] In this embodiment, the upper end of the mounting frame 1 is provided with an opening, and the bottom of the opening is recessed inward to form an inclined surface, the leakage collecting pipe 16 is provided at the bottom of the inclined surface, the filter bucket 2 is fitted in the opening on the mounting frame 1, the filter bucket 2 and the outer edge of the opening on the mounting frame 1 are rotatably connected by a hinge, a handle ring 22 is fixedly connected to the filter bucket 2, and a densely distributed sieve holes 21 are provided on the filter bucket 2, and the leakage collecting pipe 16 and the oil-water tank 3 are arranged opposite to each other. Preferably, the leakage collecting pipe 16 and the side connected to the second sewage pipe 33 on the oil-water tank 3 are arranged opposite to each other, and the oily sewage is poured on the filter bucket 2, and after being filtered through the sieve holes 21, it can enter the oil-water tank 3 through the leakage collecting pipe 16 to separate the oil and water, and the filter bucket 2 can be rotated by the hinge connected to the opening on the mounting frame 1 and lifted up by the handle ring 22, so that it can be easily maintained and cleaned.

[0045] The mounting frame 1 is symmetrically and fixedly connected with legs 11 on both sides, and a back plate 12 is fixedly connected between adjacent legs 11. A switch 13, an indicator light 14 and a thermostat 15 are installed on the back plate 12 located on one side of the heating element. The switch 13, the indicator light 14 and the thermostat 15 are electrically connected to the heating element. This scheme is the prior art, that is, the conventional structural feature of controlling heating, and its connection relationship, heating principle and corresponding structural parts are not repeated here.

[0046] In order to improve the stability during the separation process, a partition 36 is vertically connected in the oil-water tank 3, and the partition 36 is located between the first sewage pipe 32 and the second sewage pipe 33. A gap is left between the lower side of the first sewage pipe 32 and the bottom of the oil-water tank 3, and the upper end of the first sewage pipe 32 extends upward to the lower side of the opening of the oil outlet 31. The partition 36 can ensure that the liquid levels on both sides of the partition 36 are consistent when the oil-water tank 3 is filled with water, and can also prevent the oil and water mixture to be separated from the leakage collecting pipe 16 from impacting the liquid level in the oil-water tank 3, so that oil leaks from the oil outlet position regulator 34.

[0047] Furthermore, a sleeve 35 is provided at the periphery of the first sewage discharge pipe 32, and the sleeve 35 is installed on the inner side wall of the oil-water tank 3, and a gap is left between the lower end of the sleeve 35 and the bottom of the oil-water tank 3. The setting of the sleeve 35 can also prevent the oil from being discharged through the oil outlet position regulator 34, and the sewage can enter the sleeve 35 through the bottom of the sleeve 35, while the oil can be isolated, so the edge height of the sleeve 35 can be higher than the height of the oil outlet 31.

[0048] In this embodiment, the upper end of the first sewage pipe 32 may be threaded, and the oil outlet position regulator 34 is a cylindrical structure. The oil outlet position regulator 34 is installed on the upper end of the first sewage pipe 32 by threaded fitting, so that the height of the oil outlet position regulator 34 can be manually controlled and adjusted.

[0049] In order to further improve the efficiency of oil-water separation, it is also more convenient to control and adjust the height of the oil outlet position regulator 34, such as Figure 8-Figure 12As shown, a plurality of sliding grooves 3201 are embedded in the periphery of the upper end of the first sewage pipe 32, and the sliding grooves 3201 extend vertically and are arranged in a circular array on the periphery of the first sewage pipe 32. The oil outlet position regulator 34 is slidably sleeved on the periphery of the upper end of the first sewage pipe 32, and the inner wall of the oil outlet position regulator 34 is provided with a strip edge that is slidably adapted to the sliding grooves 3201; an adjusting component 38 is movably connected to the lower end of the first sewage pipe 32, and a transmission component 37 is connected between the adjusting component 38 and the oil outlet position regulator 34 for driving the oil outlet position regulator 34 to move vertically relative to the first sewage pipe 32. The sewage can be discharged through the oil outlet position regulator 34, the first sewage pipe 32 and the regulating assembly 38. The regulating assembly 38 is manually rotated, and the oil outlet position regulator 34 can be driven to move relative to the first sewage pipe 32 through the transmission assembly 37. In this way, according to the amount of oil in the sewage entering the oil-water tank 3, the height of the oil outlet position regulator 34 can be adjusted and controlled from the outside, so that the oil-water separation is more convenient and efficient. This method is more friendly to operators and can be adjusted in real time during the separation process. Because even if the oil content in the sewage is high in the initial stage, the oil content will become less and less as the separation progresses. At this time, fine-tuning the height of the oil outlet position regulator 34 can also improve the separation efficiency.

[0050] Among them, the transmission assembly 37 includes a transmission rod 3701 rotatably connected at the center of the first sewage pipe 32, the transmission rod 3701 is connected in the first sewage pipe 32 through a bracket, and the transmission rod 3701 and the bracket are rotatably connected through a bearing, a lining plate 3704 is fixedly connected to the top of the transmission rod 3701, a nut sleeve 3702 is threadedly connected to the upper periphery of the transmission rod 3701, a plurality of connecting rods 3703 are rotatably connected to the periphery of the nut sleeve 3702, and the connecting rod 3703 is rotatably connected between the end away from the nut sleeve 3702 and the inner side of the upper end of the oil outlet position regulator 34. When the adjustment component 38 drives the transmission rod 3701 to rotate, it can drive the nut sleeve 3702 to move vertically at the upper end of the transmission rod 3701, thereby pulling and driving the oil outlet position regulator 34 to move vertically, so that the height of the oil outlet position regulator 34 can be controlled by the forward and reverse rotation of the transmission rod 3701. The cooperation between the oil outlet position regulator 34 and the sliding groove 3201 can prevent the oil outlet position regulator 34 from rotating, and facilitate vertical and stable movement.

[0051] In order to facilitate control and adjustment, the adjustment assembly 38 includes a sleeve 3801 movably sleeved on the outer periphery of the lower end of the first sewage pipe 32, and a connecting rod 3803 is provided in the sleeve 3801 through a plurality of assembly rods 3802, and the connecting rod 3803 is transmission-connected to the transmission rod 3701. In this way, the rotation of the sleeve 3801 can synchronously drive the transmission rod 3701 to rotate, and then control and drive the oil outlet position regulator 34 to move vertically. The adjustment assembly 38 is also a cylindrical structure, which will not affect the discharge of sewage.

[0052] In order to maintain the high stability of the oil outlet position regulator 34, the lower edge of the first sewage pipe 32 is inlaid with an anti-slip sleeve 3202, and the anti-slip sleeve 3202 can preferably be made of rubber or silicone. The lower end of the transmission rod 3701 is embedded with a blind hole 3705, and the end of the connecting rod 3803 is fitted with the lower end of the transmission rod 3701. The connecting rod 3803 is fixedly connected with an insertion rod 3804 that slides with the blind hole 3705, and a spring is connected between the insertion rod 3804 and the blind hole 3705. During use, first pull the sleeve 3801 downward to disengage the remaining anti-slip sleeves 3202. At this time, the transmission rod 3701 can be rotated to drive the transmission rod 3701 to rotate, and then the oil outlet position regulator 34 can be controlled to adjust the height. After the adjustment is completed, push the sleeve 3801 upward. The sleeve 3801 and the anti-slip sleeve 3202 can avoid shaking through the friction force of the tight fit. The insertion rod 3804 and the blind hole 3705 can slide vertically and can be driven axially. Therefore, preferably, the cross-sections of the blind hole 3705 and the insertion rod 3804 are both polygonal structures, so the vertical movement can slide relative to each other, and the axial direction can maintain stable transmission. Such a setting can facilitate manual control to drive the oil outlet position regulator 34 to adjust the height, which is cleaner and more convenient for operators, and can be adjusted at any time.

[0053] In order to reduce the obstruction of sewage passing through the first sewage pipe 32 and avoid excessive dirt on each structural component that is inconvenient to clean, Figure 13-Figure 15As shown, a plurality of sliding grooves 3201 are embedded in the periphery of the upper end of the first sewage pipe 32, and the sliding grooves 3201 extend vertically and are arranged in a ring array on the periphery of the first sewage pipe 32. The oil outlet position regulator 34 is slidably sleeved on the periphery of the upper end of the first sewage pipe 32, and the inner wall of the oil outlet position regulator 34 is provided with a strip edge that is slidably adapted to the sliding grooves 3201; the lower end of the first sewage pipe 32 is movably connected with an adjustment component 38, and the first sewage pipe 32 is slidably provided with a There are multiple lifting rods 39, and the inner wall of the first sewage pipe 32 is provided with a guide groove for the lifting rod 39 to slide vertically. One end of the lifting rod 39 is fixedly connected to the inner side of the upper end of the first sewage pipe 32, and the outer periphery of the lower end of the lifting rod 39 is fixedly connected and provided with a toothed ring 3901. The adjustment component 38 is a cylindrical structure, and the inner wall is tapped with an internal thread. The inner side of the upper end of the adjustment component 38 is rotatably connected to the outer periphery of the lower end of the first sewage pipe 32, and the inner wall of the adjustment component 38 is threadedly matched with the toothed ring 3901. When the adjustment component 38 is rotated, it can be matched with the toothed ring 3901. The lifting rod 39 and the toothed ring 3901 can only slide vertically through the guide groove. Therefore, the cooperation between the adjustment component 38 and the toothed ring 3901 will only drive the lifting rod 39 to move vertically, thereby controlling and driving the oil outlet position regulator 34 to adjust the height in the vertical direction. In order to maintain the stability of the height of the oil outlet position regulator 34, a damping bearing is preferably used for rotational connection between the adjustment component 38 and the first sewage pipe 32.
