Description

Technical Field

[0001] The utility model relates to the technical field of drilling fluid additive production, in particular to a screening device for drilling fluid additive production. Background Art

[0002] Drilling fluid additives are used in conjunction with drilling mud during the drilling process to improve the function of drilling mud and facilitate mining. During the production of additives, their diameter needs to be controlled and screened, and special screening equipment is required for screening.

[0003] During the use of the existing screening device for the production of drilling fluid additives, since there are a variety of raw materials with different particle sizes in production, it is usually necessary to use sieve plates with different apertures for multiple screenings. Multiple screenings mean that the raw materials need to undergo multiple repeated operations to complete sorting, which prolongs the overall screening time and reduces the screening efficiency. Moreover, the sieve plate will wear out or even get clogged after long-term use, reducing the accuracy of the screening material, so it needs to be replaced regularly. The sieve plate is usually fixed to the main body of the device with multiple bolts. When installing or disassembling it, it is necessary to use tools to screw on or remove the bolts in turn. The disassembly and assembly steps are cumbersome, which reduces the convenience of replacing the sieve plate. Utility Model Content
