Description

Technical Field

[0001] This utility model relates to an oil-water separation device. Background Technology

[0002] As people's living standards improve, more and more people are dining out. However, leftover food from restaurants contains a significant amount of waste oil, making the treatment of oily wastewater a major problem. Currently, oil-water separators are generally used to separate the oil and water.

[0003] In the oil-water separation process, the oil-water mixture enters the chamber through the inlet. After being separated by a baffle, the grease floats on the water surface, while the water passes through the bottom of the baffle and flows out from the outlet below. In actual use, solid impurities carried in the oil and water will settle at the bottom of the oil-water separator. This results in solid residue, requiring additional steps to remove the solids, which may severely affect the efficiency of oil-water separation.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a new type of oil-water separation device with greater industrial application value. Utility Model Content

A stirring component 6 for stirring grease is connected inside the heating and stirring chamber 5. A heating rod 7 for heating grease is connected to the heating and stirring chamber 5. A cleaning component 8 for cleaning the oil-water separation chamber is connected to the oil-water separation chamber 1. The impurity separation component 3 includes an impurity separation chamber 31, the lower end of which is connected to the impurity separation pipe 2. The impurity separation chamber 31 has an inlet port on its upper side, and an inlet pipe 32 is connected to the inlet port. A filter screen 33 for filtering impurities is connected inside the impurity separation chamber 31. The filter screen 33 is located below the inlet pipe 32 and has an inclined structure. An impurity separation cylinder 34 is connected to the outside of the impurity separation chamber 31. The drive shaft of the impurity separation cylinder 34 passes through the impurity separation chamber 31 and is connected to a push rod that moves inside the impurity separation chamber 31. A push plate 35 that slides on the filter screen 33 is connected to the push rod. A collection port 36 for collecting impurities is opened on the outside of the impurity separation chamber 31 opposite to the impurity separation cylinder 34.

[0021] In this embodiment, the stirring assembly includes a stirring motor and stirring blades. The stirring motor is connected to the outside of the heated stirring chamber. The drive shaft of the stirring motor extends into the heated stirring chamber through a stirring connecting rod. The stirring connecting rod is connected to stirring blades for stirring oil, which can stir the oil and make it fluid.

[0022] In this embodiment, a fixed bracket 9 is connected to the upper part of the oil-water separation chamber 1. The cleaning assembly 8 is connected to the oil-water separation chamber 1 via the fixed bracket 9. The cleaning assembly 8 includes a horizontal multi-stage centrifugal pump 81 and several end-connected backwash pipes 82. The horizontal multi-stage centrifugal pump 81 is connected to the fixed bracket, and its outlet is connected to one end of each backwash pipe 82. The other end of each backwash pipe 82 is connected to the oil-water separation chamber 1 via several end-connected backwash pipes 82. The fixed bracket facilitates the installation of the cleaning assembly. A control box 10 is connected to the fixed bracket 9, which contains a PLC for control.

[0023] In this embodiment, the filter screen 33 has a V-shaped structure, and the push plate 35 also has a V-shaped structure. The bottom of the push plate 35 is provided with a scraper that contacts the filter screen 33. The V-shaped filter screen can collect impurities over a larger area, and also facilitates the smooth flow of oil and water. Then, in conjunction with the push plate and the cylinder, impurities can be quickly removed. The operation of the cylinder depends on the settings of the operator at the back end. Generally, it pushes once every 5 to 10 seconds to clean the filter screen, preventing the accumulation of impurities and allowing oil and water to pass through quickly.

[0024] In this embodiment, a cleaning connection pipe is connected to the bottom of the impurity separation chamber 31, and a 360° rotating cleaning nozzle 37 is connected to the cleaning connection pipe extending into the impurity separation chamber 31. After the impurity separation chamber is cleaned, it is cleaned as quickly as possible, improving the cleanliness of the impurity separation chamber and preventing oil accumulation from affecting subsequent separation.

[0025] In this embodiment, the oil-water separation chamber 1 is connected to a first partition 11 and a second partition 12, which divide the oil-water separation chamber 1 into a first cavity 13, a second cavity 14, and a third cavity 15. The bottoms and tops of the first cavity 13, the second cavity 14, and the third cavity 15 are interconnected. Simultaneously, the bottom of the impurity separation pipe 2 extends into the first cavity 13 and reaches the middle of the first partition 11, while the bottom of the oil-water inlet pipe 4 extends into the third cavity and reaches the middle of the second partition. The second cavity is connected to the heating and stirring chamber 5. Oil and water enter their respective cavities through different channels and are separated by the partitions.

[0026] In this embodiment, the heating and stirring chamber 5 and the oil-water inlet pipe 4 are connected to the exhaust pipe, which can prevent the storage of gas in the chamber and enable rapid removal.

[0027] The working principle of this utility model is as follows: In actual operation, oil and water containing impurities enter the first chamber after passing through the impurity separation component, while oil and water with impurities removed enter the third chamber through the oil and water inlet pipe. Under the action of the first and second partitions in the oil-water separation chamber, oil and water are separated. The oil enters the heating and stirring chamber. Due to the characteristics of oil, it needs to be kept in a flowing state by the stirring component and heating rod to facilitate subsequent discharge, while the wastewater is discharged through the drain outlet of the oil-water separation chamber.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
