Description

Technical Field

[0001] The invention belongs to the technical field of waste grease treatment, and in particular relates to a novel oil-water separation device for waste grease. Background Art

[0002] In the process of treating waste grease, oil-water separation is a key step. Existing waste grease oil-water separation devices mainly use a static method after filtering treatment to achieve oil-water separation through natural gravity sedimentation. Specifically, the waste grease that has been initially filtered to remove large particles of impurities is introduced into a static container, and the density difference between oil and water is used to make the oil float naturally on the water surface. After a period of static standing, the oil and water layers are clearly separated, and then the water at the bottom or the grease at the top is discharged through a liquid pump.

[0003] However, the existing technology has some obvious shortcomings. First, when the manual control liquid pump is outputting water or oil, it is very easy to output excess oil or water together, resulting in incomplete separation and affecting the subsequent treatment effect. In addition, the existing static separation device occupies a large area, the equipment is simple, the operation is inconvenient, and it is difficult to achieve automatic control, which increases labor costs and operation difficulties. Therefore, we proposed a new oil-water separation device for waste grease to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that in the existing waste grease treatment device, after the oil and water are separated, when the water or oil is discharged through the manually controlled liquid pump, it is very easy to discharge excess oil or water together, resulting in incomplete separation and affecting the subsequent treatment effect.

[0005] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0046] The method of use of the present invention is as follows:

[0047] When in use, the filtered waste oil is introduced into the static box 2. After the oil and water are statically separated and separated, the laser photoelectric switch is controlled by the controller 7 to work. The laser emitted by the transmitting end of the laser photoelectric switch on the first movable seat 64 can be received by the receiving end on the second movable seat 65 when passing through the strip-shaped transparent cover 5 and the water layer. The second motor 63 starts to work, cooperates with the friction wheel and the belt to drive the two threaded rods 62 to rotate, so that the first movable seat 64 and the second movable seat 65 move upward synchronously until the laser passes through the transparent cover 5 and the oil layer. The laser cannot be received by the receiving end under the larger refractive index of the oil layer, the second motor 63 stops working, and the rangefinder body 652 starts working;

[0048] When the rangefinder body 652 is working, the distance between the oil-water separation point and the baffle 653 can be measured, thereby measuring the distance between the oil-water separation point and the first baffle 4 and the second baffle 51, and transmitting the data to the controller 7. At this time, the controller 7 controls the first motor 22 to work, and the first motor 22 drives the driving rod 23 to rotate, so that the threaded sleeve 24 and the movable plate 21 move vertically upward under the limiting action of the limiting rod 25, and the oil and water in the static box 2 are supported upward. The moving distance is the same as the distance measured by the rangefinder body 652, and the oil-water separation point can be moved up to the same plane as the first baffle 4 and the second baffle 51;

[0049] The air pump works and applies pressure to the mounting grooves of the first mounting plate 26 and the second mounting plate 52 through the air pipe, causing the first partition plate 4 and the second partition plate 51 to extend into the still box 2 and the strip transparent cover 5, thereby separating the oil and water in the still box 2 and the strip transparent cover 5. At this time, the liquid pump 3 and the solenoid valve are opened to discharge the water in the still box 2 and the strip transparent cover 5, thereby facilitating further processing of the oil above the first partition plate 4 and the second partition plate 51.
