Abstract

The invention relates to the field of building material processing equipment, in particular to a negative pressure screening equipment used for the preparation of concrete composite admixtures, comprising: a screening tank, the top and bottom of which are respectively provided with a first feed inlet and a first outlet The feed port, the top of the screening tank is also provided with an air inlet pipe, and the peripheral surface of the screening tank is also provided with a miscellaneous outlet for discharging large-volume admixtures; the inclined screw feeder is arranged on one side of the screening tank and the top is connected to the The first feed port is connected; the bulk feeder, the working end is set on the top inside the screening tank; the sieve plate is coaxially set in the screening tank and is located on the top of the working end of the bulk feeder; the multi-task rotary negative pressure device, the negative pressure part is inclined The downward coaxial setting is inside the screening tank and is located at the bottom of the sieve plate; the coaxial pusher is coaxially fixed on the top of the output shaft of the multi-function rotary negative pressure device, and the bottom end of the coaxial pusher slides with the top of the sieve plate Coordination; horizontal screw feeder, the feed end is connected with the discharge end, the device can screen admixtures in large quantities.

Description

technical field [0001] The invention relates to the field of building material processing equipment, in particular to a negative pressure screen equipment used for preparing concrete composite admixtures. Background technique [0002] At present, concrete with a strength grade of not less than C60 is generally called high-strength concrete in China. After building structures, it can greatly reduce the cross-sectional size, reduce the self-weight of the structure, and make the concrete structure lighter and more beautiful. However, high-strength concrete is brittle, has a large shrinkage, and has poor crack resistance. Therefore, in the application of high-strength concrete, improving its brittleness and crack resistance is a very important issue. [0003] In the production and preparation of high-strength concrete, the amount of cement is often high, the heat of hydration is large, and the temperature stress and self-shrinkage bring hidden dangers to the cracking of high-str...
