Description

Technical Field

[0001] The utility model relates to the technical field of grain and oil processing, in particular to a filtering mechanism which is easy to clean and is used in a filtering device. Background Art

[0002] Grain and oil is a general term for cereals, beans and other grains and oils, as well as their processed products and semi-finished products. When processing grain and oil, it is necessary to filter the grain and oil to remove impurities in the grain and oil to avoid affecting the quality of the grain and oil. A grain and oil filtering mechanism is required during filtering. Since the filtered impurities accumulate on the outside of the filter, the grain and oil filtering mechanism needs to be cleaned after use.

[0003] When cleaning a traditional filtering mechanism, the filter screen needs to be disassembled and impurities attached to the filter screen need to be manually cleaned. After cleaning, the filter screen needs to be reinstalled, which is inconvenient to operate and the manual cleaning efficiency is low. Therefore, the utility model proposes a filtering device with an easy-to-clean filtering mechanism to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a filter mechanism for a filter device which is easy to clean, so as to solve the problems raised in the above-mentioned background technology.

[0006] Preferably, the recoil cleaning device comprises a reflux pipe, and the right end of the reflux pipe is fixedly connected to a recoil pipe.

[0007] Preferably, the left end of the reflux pipe is fixedly connected to the upper end surface of the flushing chamber, and the left outer end of the reflux pipe is fixedly connected to a reflux piston.

[0008] Preferably, a recoil pump is fixedly connected to the right outer end of the reflux pipe.

[0009] Preferably, a filter screen is arranged at the connection between the filter barrel and the flushing chamber.

[0010] Preferably, the middle lower end of the reflux pipe is connected to a storage box, and the storage box is fixedly connected to the upper end surface of the flushing cavity.

[0011] Preferably, a sealing sleeve at the upper end of the flushing cavity is provided with a reflux pipe.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model discloses to be provided with the recoil cleaning device, thereby makes it unnecessary to disassemble the filter screen when the filter device needs to be cleaned after use, and the impurities attached to the filter screen can be washed away by the recoil action and deposited in the waste barrel. When a large amount of impurities are collected in the waste barrel, it is only necessary to disassemble the thread of the waste barrel and deal with the waste in the barrel, thus reducing the steps of manual disassembly and installation and improving the cleaning efficiency of the filter mechanism.
