Abstract

The invention provides a sieve plate device preventing hole blocking in a screening blind area. The sieve plate device comprises a compressed air system and a sieve body which are arranged sequentially from top to bottom. The sieve body comprises a sieve net provided with a plurality of sieve holes. The compressed air system comprises a flat air bag matched with the sieve net in shape. A pluralityof acicular air pipes corresponding to the sieve holes are arranged at the bottom of the air bag. Each acicular air pipe comprises an upper pipe end communicating with the air bag, and a lower pipe end communicating with the outside air, wherein the pipe hole of the upper pipe end is of a straight cylinder structure, and the pipe hole of the lower pipe end is of a wide-end-up conical structure. Aplurality of compressed air inlet pipes are arranged at the top of the air bag and are connected with outside compressed air pipelines. The compressed air system with the acicular air pipes is arranged above a sieve plate, the acicular air pipes blow air to the sieve holes of the sieve net to blow off viscous matter blocking the sieve holes, blocking prevention efficiency is high, and cost for cleaning the sieve net can be lowered effectively.

Description

technical field [0001] The invention belongs to the technical field of screening equipment, and in particular relates to a sieve plate device for preventing holes from being blocked in screening blind areas. Background technique [0002] Fine-grained wet and sticky materials are one of the most difficult types of materials encountered in the current screening process. The sieve plates currently used in the market will encounter serious blockage in the screening blind area when processing fine-grained wet and sticky materials. This will lead to a rapid decrease in screening efficiency, and it is extremely difficult to clean the screen surface. More importantly, the working time of the entire screening system and even the crushing system will be prolonged, which will seriously increase the power consumption of the enterprise and the consumption of equipment spare parts. [0003] The patent "An Anti-clogging Classifying Sieve" (application number: CN201410600145.5) discloses an...
