Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically, to an oil-water separation device with a sedimentation function. Background Art

[0002] There are many oil-water separation technologies nowadays. Commonly used methods include gravity separation, coarse granulation, filtration, flotation, adsorption, membrane separation, ultrasonic, chemical, biological and other technologies. In gravity separation, the principle of gravity separates the suspended matter from the mixed solution. The ratio of the mixed solution will affect the thickness of the water layer and the oil layer. The existing devices cannot sense the oil level and cannot ensure that the exported oil has a low water content, and the oil-water separation processing capacity is poor.

[0003] The utility model patent with patent publication number CN202210720509.8 discloses an oil-water separation device for sewage with a sedimentation function, including a sedimentation tank, a support plate, a double screw, a first reversing mechanism, a driving mechanism, a second reversing mechanism and an oil discharge mechanism. The first reversing mechanism includes an upper sliding ring, a middle sliding ring, a lower sliding ring and a switching assembly; the utility model provides an oil-water separation device for sewage with a sedimentation function to solve the problem that the existing device cannot sense the oil level, thereby solving the problem that the derived oil has a low water content and poor oil-water separation processing capacity.

[0004] However, when this structure is actually used, the filter screen will filter out larger impurities, and the filtered impurities will sink to the bottom of the tank. However, when too many impurities accumulate at the bottom of the tank, it is easy to make the impurities difficult to clean, and eventually cause the filter screen to be blocked. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides an oil-water separation device with a sedimentation function to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oil-water separation device with a sedimentation function, comprising an outer shell, a filter tank is provided inside the outer shell, a filter plate is provided inside the filter tank, a sediment outlet is provided on the filter plate, a sedimentation tank is provided on one side of the filter tank, an impurity outlet is provided on one side of the filter tank, and an impurity cleaning component is provided inside the filter tank.

[0007] Preferably, the impurity cleaning component includes a load-bearing plate, which is arranged at the bottom of the filter tank. A limiting slot is provided inside the filter tank, and a fixing rod is provided inside the limiting slot. One end of the fixing rod is fixedly connected to the load-bearing plate, and a limiting protrusion is provided on the outer side of the fixing rod. One side surface of the limiting protrusion is fixedly connected to the fixing rod. The fixing rod is slidably connected to the limiting slot, and the cross-sectional shape of the fixing rod is set to be L-shaped.

[0008] Through the above scheme, it can be seen that the impurities sink to the bottom of the filter tank after being blocked by the filter net. Then the staff controls the fixed rod to rise and uses the fixed rod to drive the load-bearing plate to rise, so that the debris on the top of the load-bearing plate is discharged outward through the impurity outlet to the inside of the aggregate tank. After the impurities are discharged, the fixed rod drives the load-bearing plate to descend through the relationship between the limiting protrusions on both sides and the limiting slots until the bottom of the load-bearing plate contacts the bottom of the filter tank, thereby completing the cleaning of the impurities, thereby avoiding the blockage of the filter net and improving the practicability of the device.

[0009] Preferably, a fixing block is provided on one side surface of the shell, and the fixing block is fixedly connected to the one side surface of the shell. A snap-in groove is provided inside the fixing block, and a snap-in groove is provided on the inner wall of the snap-in groove. A limiting column is connected inside the snap-in groove, and one end of the limiting column passes through the upper surface of the fixing block and is movably connected to the snap-in groove.

[0010] Through the above scheme, it can be seen that the aggregate box is set on one side of the outside, and then the impurities are allowed to fall into the aggregate box through the impurity outlet by controlling the load-bearing plate, thereby realizing the collection of impurities. Therefore, the impurities can be centrally stored and transported by moving the aggregate box, thereby improving the overall cleaning ability of the device and improving work efficiency.

[0011] Technical effects and advantages of the utility model:

[0012] By setting up the impurity cleaning component, compared with the prior art, the impurities sink to the bottom of the filter tank after being blocked by the filter screen, and then the staff controls the fixed rod to rise, thereby using the fixed rod to drive the load-bearing plate to rise, so that the debris on the top of the load-bearing plate is discharged outwardly into the collecting tank through the impurity outlet, and after the impurities are discharged, the fixed rod drives the load-bearing plate to descend through the relationship between the limiting protrusions on both sides and the limiting card slots until the bottom of the load-bearing plate contacts the bottom of the filter tank, thereby completing the cleaning of the impurities, thereby avoiding the clogging of the filter screen, and improving the practicality of the device;

[0013] By setting up an aggregate box, compared with the prior art, the aggregate box is set on one side of the outside, and then the impurities are allowed to fall into the aggregate box through the impurity outlet by controlling the load-bearing plate, thereby realizing the collection of impurities. Therefore, the impurities can be centrally stored and transported by moving the aggregate box, thereby improving the overall cleaning ability of the device and improving work efficiency.
