Powder sampling equipment in concrete production

Abstract

The invention relates to the technical field of concrete production, and discloses powder sampling equipment in concrete production. The powder sampling equipment comprises a device box body, the device box body is internally provided with a powder sampling mechanism, a static elimination mechanism and an electric heating blanking mechanism; and the powder sampling mechanism comprises a first pipeline, a second pipeline, a powder taking shell, a first fixing rod, a first double-head motor, a first motor shaft, a second motor shaft, a first negative ion generator and air draft fan blades. By arranging the double-end motor, the negative-ion generator and the electric heating pipe on the motor shaft in the sampling shell, powder in the box body can be pumped out to the outside for sampling by utilizing the double-end motor and the draft fan blades, so that static electricity in the powder and a pipeline can be eliminated through the negative-ion generator, the powder is prevented from being adsorbed in the inner wall of the pipeline, the second motor shaft drives the electric heating pipe and the stirring rod at the same time, the powder is dried and discharged at the same time, and powder wetting and discharging blockage are avoided.

Description

Technical field [0001] The present invention relates to the field of concrete production, and is specifically a powder sampling apparatus in concrete production. Background technique [0002] Concrete is currently the most used in the world, the most widely used artificial building materials. With the continuous development of the economy, the development of the construction industry in my country has increased, and the construction of infrastructure has increased, and the concrete is one of the largest building materials, the demand for concrete is flying. In particular, the high-performance requirements of ultra-high-rise buildings such as ultra-high pumping performance, high-strength high performance, and self-real performance, need to pass a large number of small tests, multiple trials, and designed concrete coordination ratios . [0003] Patent No. CN201821630211.3 discloses a powder sampling apparatus in concrete production, including a fixing frame, a wheel having a wheel,...

Problems solved by technology

[0004] However, during the use of the existing powder sampling equipment in concrete production, not only the powder will be adsorbed on the inner wall of the pipeline due to static electricity, which will affect the sampling of the powder, but also the surface of the pipeline inside the box will also adsorb the powder. , not only that, it is impossible to combine the heating mechanism and the unloading mechanism to perform heating and unloading at the same time
