Abstract
Description
Technical Field
[0001] This utility model belongs to the field of petrochemical grating technology, and specifically relates to a high-strength petrochemical grating. Background Technology
[0002] The petrochemical industry is a pillar industry in my country. Petrochemical production involves the use of gratings, which are widely used in hydrogenation reactors, desulfurization reactors, molecular sieves, gas desulfurization reactors, and other absorption systems, playing a certain filtering role. However, because petrochemical gratings are used for filtration, they are frequently subjected to scouring and corrosion by liquids and impacts by solid substances, resulting in a limited lifespan. After a period of time, petrochemical gratings need maintenance or replacement to ensure effective filtration in hydrogenation reactors, desulfurization reactors, molecular sieves, gas desulfurization reactors, and other absorption systems. However, most common petrochemical gratings are of a one-piece structure, which means that if a section of the grating or outer frame breaks, it cannot be replaced individually. This may lead to the temporary use of the broken section, resulting in a decline in its filtration performance during operation.
[0003] Secondly, when petrochemical gratings can no longer be used, they cannot be disassembled and replaced individually, so the whole thing needs to be replaced, which will result in high replacement costs and is not conducive to achieving cost reduction goals in production.
[0004] In summary, petrochemical gratings that cannot be individually disassembled and replaced have some problems in use. Therefore, it is hoped that a new structure can be proposed to solve the above-mentioned technical problems. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-strength petrochemical grid to solve the problems mentioned in the background art.
[0006] This utility model is achieved through the following technical solution: a high-strength petrochemical grid, comprising: an outer grid seat, an inner grid seat, a middle section connector, and a grid body. The outer grid seat is provided in four sets, arranged in a circumferentially divided structure. Each set of the outer grid seat is a quarter-circle structure, and the centers of the four sets of outer grid seats are the same when they are assembled. Each set of outer grid seats is provided with a grid body for filtration in the petrochemical industry on the side near the center. Between the left and right sets of outer grid seats, there is a set of inner grid seats for improving strength and assembling the two sets of outer grid seats and grid bodies. A middle section connector is provided on the upper side of the inner grid seat near the center for assembling and fixing the four sets of outer grid seats and the two sets of inner grid seats.
[0007] In a preferred embodiment, an inner ring groove is provided on the side of the outer seat of the grille near the center, and several sets of outer engaging grooves for engaging the grille body are provided on the inner sides of both the upper and lower ends of the inner ring groove.

[0012] As a preferred embodiment, the outer side of the outer seat of the grille near the middle section connector is provided with an inner connecting plate, and the lower surface of the upper plate is provided with two sets of spaced outer connecting plates at both the left and right ends.
[0013] Both the inner connecting plate and the outer connecting plate have threaded holes on their rear sides. The inner connecting plate is located inside the two sets of outer connecting plates and is connected and fixed by bolts screwed into the inner side of the threaded holes. The vertical fitting block is fitted into the inner side of the vertical fitting groove. At this time, the two sets of outer connecting plates automatically engage with the inner connecting plate. Screwing the bolts into the inner side of the threaded holes can connect and fix the middle section connecting piece with the outer seat and inner seat of the grid.
[0014] In a preferred embodiment, a set of inner support plates for improving strength is provided in the middle of the inner side of the through groove. The inner support plates have an X-shaped structure. Several sets of support columns for improving strength are provided in a circularly evenly distributed manner on the inner side of the inner annular groove.
