Vacuum drying device for polycarboxylate superplasticizer

Abstract

The invention discloses a vacuum drying device for a polycarboxylate superplasticizer. The vacuum drying device comprises a sealed tank body, a first circular opening is processed at the center of thesurface of the right side of the sealed tank body, a first rotary bearing is embedded in the first circular opening, a second rotary bearing corresponding to the first rotary bearing is arranged on the surface of the left side in sealed tank body, a motor bracket is arranged on the surface of the right side, on the position below the first circular opening, of the sealed tank body, a rotary motorwith the horizontal rotating end is arranged on upper surface of the motor bracket, and a horizontal rotating shaft connected with the first rotary bearing and the second rotary bearing in an overlapped mode is arranged at the rotating end of the rotary motor. The vacuum drying device for the polycarboxylate superplasticizer has the beneficial effects that during vacuum drying of the polycarboxylate superplasticizer, the dried polycarboxylate superplasticizer can be fully stirred, thus undried polycarboxylate superplasticizer liquid is better heated conveniently, the purpose of rapid drying is achieved, and the vacuum drying efficiency of the polycarboxylate superplasticizer is improved.

Description

technical field [0001] The invention relates to the field of polycarboxylate water reducer, in particular to a vacuum drying device for polycarboxylate water reducer. Background technique [0002] Polycarboxylate superplasticizer is a high-performance superplasticizer and a cement dispersant used in cement concrete. Widely used in highways, bridges, dams, tunnels, high-rise buildings and other projects. The product is green, non-flammable and non-explosive, and can be safely transported by train and automobile. At present, most factories use vacuum drying method to dry polycarboxylate superplasticizer into powder. In order to improve the drying efficiency of polycarboxylate superplasticizer, many vacuum drying devices for polycarboxylate superplasticizer have appeared in the market. [0003] In the existing technology, the application number: 201020251965.5, the utility model name is the patent of polycarboxylate water reducer vacuum drying device, its practical new polyca...

Problems solved by technology

[0004] However, in the above-mentioned device, in the process of vacuum drying the polycarboxylate water reducer, the stirring of the polycarboxylate water reducer is not enough to raise the dried polycarboxylate water reducer, so it cannot be used The polycarboxylate superplasticizer liquid that has not been dried is better heated, which seriously affects the vacuum drying efficiency of the polycarboxylate superplasticizer
