UHPC ultra-high performance concrete raw material screening device

Abstract

The invention discloses a UHPC ultra-high performance concrete raw material screening device, and relates to the technical field of concrete.The UHPC ultra-high performance concrete raw material screening device comprises a pretreatment box, the upper portion of the pretreatment box is provided with a feeding port, the UHPC ultra-high performance concrete raw material screening device further comprises a swing crushing mechanism, the swing crushing mechanism is arranged in the pretreatment box, and raw materials fall into the pretreatment box from the feeding port; the swinging crushing mechanism is used for crushing hardened raw materials; the falling box is arranged at the bottom of the pretreatment box and is communicated with the interior of the pretreatment box; round pipes are arranged at the two ends of the screening cylinder, and the outer side walls of the two round pipes are rotationally sleeved with supporting rings. Raw materials can be pretreated, hardened raw materials in the raw materials can be crushed, then the raw materials are quickly and efficiently screened through the screening barrel, in the process, the raw materials can be smoothly discharged, the raw material discharging speed is high, blockage is avoided, screened impurities can be efficiently and conveniently cleaned, and the screening efficiency is improved. And rapid and efficient screening of the device is ensured.

Description

technical field [0001] The present invention relates to the technical field of concrete, in particular to a UHPC ultra-high performance concrete raw material screening device. Background technique [0002] Ultra-High Performance Concrete, referred to as UHPC (Ultra-High Performance Concrete), also known as Reactive Powder Concrete (RPC, Reactive Powder Concrete), is the most innovative cement-based engineering material in the past three decades. big leap. "Ultra-high performance concrete" includes two aspects of "superior", namely ultra-high durability and ultra-high mechanical properties; [0003] Ultra-high-performance concrete can be regarded as the most durable engineering material. The mechanical properties of ultra-high-performance concrete with appropriate reinforcement are close to that of steel structure. At the same time, ultra-high-performance concrete has excellent wear resistance and anti-knock performance. Therefore, ultra-high performance concrete is particu...

Problems solved by technology

[0006] The raw material screening device in the prior art has the following disadvantages in actual use: not only will there be impurities in the raw material, but also hardening will occur due to factors in the storage environment. The screening efficiency of the existing screening device for hardened raw materials is low. Raw materials are easy to block the sieve holes during screening, and the discharge efficiency of raw materials and impurities after screening is low, so the present invention proposes a UHPC ultra-high performance concrete raw material screening device here
