Abstract

The invention provides an oil sand filter easy to clean. The oil sand filter comprises a barrel, a head cover and a filter cylinder arranged in the barrel; a cleaning opening with a bottom cover is formed in the bottom of the barrel, an annular lapping plate is fixedly arranged on the inner side wall of the barrel, the filter cylinder is connected to the lapping plate in a lapping mode, a filter cylinder cover is arranged at the top end of the filter cylinder, the side wall, the bottom and the filter cylinder cover of the filter cylinder are made of filter screens with filtration pores, and the filtration pores of the filter cylinder cover is smaller than those of the filter cylinder. The oil sand filter easy to clean has the advantages of being simple in structure, good in sand filtering effect, not prone to block the filter screens and capable of cleaning the filter screens.

Description

technical field [0001] The invention belongs to the field of oil production equipment, and in particular relates to an easy-to-clean oil sand filter. Background technique [0002] In the process of oil extraction, oil is often mixed with sand, especially in the late stage of oil field development, more and more sand is produced in oil layers, sand-containing oil must be processed before subsequent processing, otherwise it will affect the follow-up of oil processing and use. In order to filter out the sand mixed in petroleum, there are many types of sand filter devices, but the existing equipment has problems such as poor sand filter effect, easy clogging of the filter screen, complicated equipment structure, and difficulty in cleaning the filter screen after clogging. Contents of the invention [0003] In view of this, the present invention aims to propose an easy-to-clean oil sand filter to solve the problems in the prior art that the sand filter effect is not good, the ...
