DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] Embodiment one

[0021] Please refer to Figures 1-3 In the embodiments of the utility model, a drainage structure of a dirty oil-water separator includes: a separation tank 1; the separation tank 1 is provided with an oil suction port and a sewage outlet.

[0022] A drainage tank 2 is fixedly installed on the top of the separation tank 1, and the drainage tank 2 is provided with a liquid inlet; a heater can be arranged on the drainage tank 2, which can heat the dirty oil-water when the temperature is too low, reduce the viscosity of the dirty oil-water, reduce the flow loss, maintain the kinetic energy of the dirty oil-water, and promote the aggregation of the dirty oil.

[0023] A connecting pipe 5 is installed between the separation tank 1 and the drainage tank 2, one end of the connecting pipe 5 is communicated with the separation tank 1, and the other end of the connecting pipe 5 is communicated with the drainage tank 2; an electromagnetic valve is arranged on the connecting pipe 5, which can block the flow of dirty water when needed.

[0024] A shunt plate assembly 6 is installed in the interior of the separation tank 1, which is used for shunting dirty oil-water, and the shunt plate assembly 6 includes a cylindrical plate 61, a conical plate 62 and four arc plates 63; the conical plate 62 is fixedly installed on the top of the cylindrical plate 61 and located directly below one end of the connecting pipe 5; the four arc plates 63 are symmetrically distributed and fixedly installed on the outer circumferential side of the cylindrical plate 61; the outer circumferential side of the arc plate 63 is fixedly connected with the inner wall of the separation tank 1; and a plurality of through holes are formed in the arc plate 63.

[0025] The dirty oil water first enters the inside of the flow guide box 2 through the liquid inlet of the flow guide box 2, and then flows into the separation box 1 through the connecting pipe 5. In order to improve the dispersibility of the dirty oil water and optimize its flow characteristics, the flow distribution plate assembly 6 is installed inside the separation box 1. The flow distribution plate assembly 6 is composed of a cylindrical plate 61, a conical plate 62, and four arc-shaped plates 63. These structures work together to achieve effective distribution of the dirty oil water. Specifically, the conical plate 62 is fixedly installed on the top of the cylindrical plate 61, directly below one end of the connecting pipe 5. The initial dispersion of the dirty oil water entering from the flow guide box 2 is onto the four arc-shaped plates 63. The four arc-shaped plates 63 are symmetrically distributed and fixedly installed on the outer peripheral side of the cylindrical plate 61, and their outer peripheral side is fixedly connected with the inner wall of the separation box 1. The dirty oil water is further dispersed by the multiple through holes formed on the arc-shaped plates 63, increasing the falling area of the dirty oil water and promoting the aggregation and floating of oil droplets, thereby improving the separation efficiency. Through this structural design, the falling flow of the dirty oil water in the separation box 1 is more orderly, reducing the direct impact on the inner wall of the separation box 1, reducing wear and tear, prolonging the service life of the equipment, and improving the dispersibility of the dirty oil water, which helps to more efficiently achieve oil-water separation.

[0026] As shown in Figure 3 , in this embodiment, a screw rod 3 is rotatably installed between the top and bottom of the inner wall of the flow guide box 2. A drive motor 4 is fixedly installed on the top of the flow guide box 2, and the output end of the drive motor 4 is fixedly connected with the top end of the screw rod 3.

[0027] When the dirty oil water is injected into the liquid inlet of the flow guide box 2, the drive motor 4 is started to drive the screw rod 3 to rotate, thereby stirring and rolling the entering dirty oil water, generating a large number of bubbles in the dirty oil water, facilitating subsequent oil-water separation.

[0028] As shown in Figure 2 , in this embodiment, a flow guide plate 7 is fixedly installed on the inner wall of the separation box 1, and a plurality of flow distribution holes are provided on the flow guide plate 7, the number of which is greater than that of the through holes on the arc-shaped plates 63.

[0029] Through the cooperation of the flow guide plate 7 and the multiple flow distribution holes thereon, the dirty oil water can be further dispersed and fallen, further promoting the aggregation and floating of oil droplets, thereby further improving the oil-water separation efficiency.

[0030] As shown in Figure 3 , in this embodiment, a vertical plate 12 is fixedly installed between the top and bottom of the inner wall of the separation box 1, which divides the inside of the separation box 1 into two separation chambers 11. The number of the connecting pipes 5 is two, which respectively communicate with the two separation chambers 11. The inside of each of the two separation chambers 11 is provided with the flow distribution plate assembly 6 and the flow guide plate 7.

[0031] The separation tank 1 is separated into two separation chambers 11 by the vertical plate 12, and the internal structure is the same, which aims to increase the number of separation chambers 11, which can increase the processing capacity of the entire separator, so that the device can process larger flow, and two separation chambers 11 can be processed at the same time, which improves the separation efficiency, especially in applications that require rapid processing of large amounts of fluid, and the arrangement of two separation chambers 11 prevents the other from continuing to work when one separation chamber 11 fails, thereby improving the safety and reliability of the entire system.

[0032] Embodiment two

[0033] On the basis of embodiment one, in order to avoid the oil droplets that float up after the separation of the oil and water being mixed with the water below again when the oil is extracted, affecting the separation effect.

[0034] As Figures 1-2 shown, in this embodiment, two rotating shafts 8 are symmetrically and fixedly installed between the two sides of the inner wall of the separation chamber 11, the outer surfaces of the two rotating shafts 8 are fixedly installed with baffles 9, and the separation tank 1 is installed with a rotating assembly 10 for driving the relative rotation of the two rotating shafts 8. One end of the rotating shaft 8 penetrates the separation tank 1 and extends to the outside, the rotating assembly 10 includes two gears 101 fixedly installed at one end of the two rotating shafts 8, respectively, the two gears 101 are engaged, one side of the separation tank 1 is fixedly installed with a rotating motor 102, and the output end of the rotating motor 102 is fixedly connected with one of the gears 101. The baffle 9 can effectively separate the oil and water, prevent the oil droplets from mixing with the water again, in the separation tank, the oil will naturally float to the water surface due to its smaller density, the baffle 9 can prevent these oil droplets from mixing with the water below again, and ensure the oil-water separation effect.

[0035] When the oil and water are injected into the separation chamber 11 for separation, the oil naturally floats to the water surface for separation, the rotating motor 102 can be started to drive one of the gears 101 to rotate, since the two gears 101 are engaged, the two gears 101 can be rotated in opposite directions, and the two rotating shafts 8 can be relatively rotated, so that the two baffles 9 originally in the vertical state in the separation chamber 11 tend to be parallel, thereby separating the oil floating to the water surface and the water below, so that the oil droplets can be concentrated and collected, facilitating subsequent recovery or treatment of the oil. When not in use, the two baffles 9 are in a vertical state, which does not affect the separation of the oil and water.

[0036] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, the scope of the present application being defined by the claims appended hereto rather than by the above description, and all the changes which fall within the meaning and the scope of the equivalent elements of the claims are intended to be embraced therein.
