[0002] The petrochemical industry, referred to as petrochemicals, generally refers to the chemical industry that uses oil and natural gas as raw materials. It is an important part of the chemical industry and plays an important role in the development of the national economy. It is one of the pillar industries in my country. Petrochemicals refers to the processing industry that uses oil and natural gas as raw materials to produce petroleum products and petrochemical products. Petroleum products are also called oil products, mainly including various fuel oils and lubricants, as well as liquefied petroleum gas, petroleum coke, paraffin and asphalt.

[0003] In the existing sieve plate mechanism for petrochemical industry, for example, a sieve plate mechanism for petrochemical industry disclosed in the utility model patent with application number 202020108695.6, the utility model sets a first limit block and a second limit block, and the second limit block is located at the lower left of the first limit block, and the cross-section of the sieve plate is set to be an inclined panel cut toward the lower left corner. The length of the sieve plate is greater than the inner diameter of the box body, so that when impurities block the sieve plate holes on the crude oil landing point, the crude oil can flow down the inclined surface to the unblocked sieve holes for filtration, thereby avoiding the crude oil from filtering in the sieve. The crude oil can accumulate in front of the clogged sieve holes on the plate, thereby achieving the effect of shortening the residence time of the crude oil on the sieve plate and improving the filtration efficiency. By setting the cross-section of the sieve plate to be an inclined panel with a slant toward the lower left corner, large particles of impurities can directly roll down along the inclined surface and accumulate on the top left side of the sieve plate after colliding with the sieve plate, which is convenient for centralized cleaning. By setting the two first connecting blocks and the second connecting blocks to have screw holes inside, the internal threads of the two screw holes are connected to the fixing screws, which can make it more convenient to clean the disassembled box body and the box cover in the sieve plate.
