Description

Technical Field

[0001] The utility model belongs to the technical field of oil collecting tanks and relates to an oil collecting tank of an aluminum foil rolling mill. Background Art

[0002] Aluminum foil rolling mills are used for further rolling of aluminum plates, and can produce aluminum foils of various thicknesses. With the improvement of people's living standards, the application of aluminum foil in food, beverages, dairy products, medicine, daily chemicals, electronic products, cigarette packaging and other fields has developed rapidly. The cleanliness of rolling oil is an important guarantee for the quality of aluminum foil. However, there are many problems with the existing aluminum foil rolling mill oil collection tank. First, the filter area is small, and it is not easy to fully filter the rolling oil; second, the return oil port cannot filter ferromagnetic impurities, resulting in rust in the recycled rolling oil; these cannot guarantee the clean production of aluminum foil, affecting the quality of aluminum foil; and the filter and the external piping occupy the same area, making it difficult to clean the filter later, and the cleaning is time-consuming and labor-intensive, and inefficient. Utility Model Content

[0003] The purpose of the utility model is to solve the above-mentioned problems existing in the prior art and to provide an oil collecting tank for an aluminum foil rolling mill, which has a large filtering area and high filtering efficiency; can clean the ferromagnetic substances in the recovered rolling oil, ensure the cleanliness of the rolling oil, and ensure the quality of the produced aluminum foil; and is convenient for cleaning, repairing and replacing components such as piping and filter screens.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: an oil collecting tank of an aluminum foil rolling mill, comprising a shell, both sides of the upper end of the shell are arranged as fixed plates fixed on the rolling mill base, and the lower end is a collecting tank with one end closed; the upper end of the collecting tank is an inclined collecting cover, and the lower end is a rectangular oil collecting tank arranged in the middle of the lower end of the inclined collecting cover; the oil collecting tank is provided with an oil outlet nozzle at the other end away from the closed end of the collecting tank; a Z-shaped primary filter screen is fixed on the upper end surface of the oil collecting tank, and a rectangular secondary filter screen is provided at the lower end of the primary filter screen at the oil outlet nozzle end; the oil collecting tank is provided with a magnetic grid at the oil outlet nozzle.

[0005] Further preferably, the bottom surface of the oil collecting tank is an inclined surface with a high closed end and a low oil outlet end, so that the rolling oil collected in the oil collecting tank can easily flow to the oil outlet end, and the bottom surface no longer accumulates rolling oil.

[0006] Further preferably, the magnetic grid includes a rectangular frame, a support plate fixed in the rectangular frame, a filter screen fixed to one end face of the rectangular frame, and a magnetic bar fixed between the rectangular frame and the support plate and between two adjacent support plates. The magnetic grid has the function of filtering the rolling oil three times and also has the function of magnetically attracting ferromagnetic impurities in the rolling oil.

[0007] Further preferably, a connecting flange is installed on the oil outlet nozzle to facilitate connection with an external oil outlet pipeline.

[0008] Compared with the prior art, the advantages of the present invention are:

[0009] The primary filter fully covers the oil collection tank, increasing the filtering area of ​​the rolling oil and thus improving the filtering efficiency. 2. After the primary filtration, the rolling oil is further filtered through the secondary filter, and finally flows out from the oil nozzle for recovery after passing through the magnetic grid. This not only makes the other impurities in the rolling oil filtered more thoroughly, but also filters the ferromagnetic substances in the rolling oil, ensuring that the recovered rolling oil does not contain rust, achieving clean production and ensuring the quality of the produced aluminum foil. 3. The primary filter, secondary filter and magnetic grid are located in the middle of the lower end of the inclined collection cover of the collection tank. The external piping can be arranged in the inclined collection cover on both sides of the oil collection tank. The installation of the piping is separated from the primary filter, secondary filter and magnetic grid, making the piping installation more convenient and reasonable, and does not affect the cleaning, maintenance and replacement of components such as the filter.
