Oil filtering device free of disassembly and washing

Abstract

An oil filtering device free of disassembly and washing comprises a shell, a filter element mounted in the shell, an oil inlet pipe and an oil outlet pipe, the oil inlet pipe and the oil outlet pipe are connected with the shell; the filter element is mounted between a bottom plate and an upper gland, the bottom plate is obliquely fixed to the bottom in the shell, and the upper gland is fixed to the upper end of the filter element; the filter element comprises multiple layers of filter screens which are arranged at intervals and are coaxial with the shell, the outlet end of the oil inlet pipe is located on the upper portion of the filter screen on the innermost layer, the oil outlet pipe is connected to the bottom of the shell, and drain outlets are formed in the filter screen on the innermost layer and the lowest position of the bottom plate between the adjacent filter screens correspondingly; and the drain outlets are connected with a blow-off pipe provided with a stop valve. According to the oil filtering device free of disassembly and washing, the outlet end of the oil inlet pipe is arranged at the upper part of the filter element, and the corresponding drain outlet is formed in the bottom plate in each layer of filter screen, so that the effect of efficiently filtering without disassembly and washing is realized.

Description

technical field [0001] The invention relates to a filtering device, in particular to an oil filtering device. Background technique [0002] At present, oil filter devices are made of paper, cotton, fiber and stainless steel mesh, and multi-layer folding and folded methods are used to increase the filtration area. After the folded space is used to store impurities and dirt, due to the design and manufacturing defects of the filter container and filter element, the impurities and dirt stored in the folded space of the filter element cannot be discharged in a simple way, and the accumulation of impurities and dirt will block the filter surface , so that the oil inlet and the oil outlet form a pressure difference. If the pressure difference is too large, the filter element will break and the filter function will fail, which will eventually cause the quality of the filtered oil to decline, thereby endangering the equipment using the filtered oil. The filter elements currently on...

Problems solved by technology

After the folded space is used to store impurities and dirt, due to the design and manufacturing defects of the filter container and filter element, the impurities and dirt stored in the folded space of the filter element cannot be discharged in a simple way, and the accumulation of impurities and dirt will block the filter surface , so that the oil inlet and the oil outlet form a pressure difference. If the pressure difference is too large, the filter element will break and the filter function will fail, which will eventually cause the quality of the filtered oil to decline, thus endangering the equipment using the filtered oil.

The filter elements currently on the market cannot be cleaned when impurities and dirt have accumulated to a certain amount, and the method of replacing the filter element can only be used to remove impurities and dirt. The replaced filter element can only be scrapped once and cannot be reused, resulting in A great waste of manpower and material resources also causes some pollution to the environment
