Technical Field

The invention relates to the field of concrete water reducing agent preparation, in particular to a method and a device for synthesizing a polycarboxylic acid water reducing agent by multi-copolymerization.

Background

The polycarboxylate superplasticizer is a new generation high-efficiency superplasticizer, and is divided into a slow-setting type, a slow-release type, an early-strength type, a slump retaining type, a mud-resistant and salt-resistant type, a high comprehensive performance type and the like according to the performances and use occasions of the polycarboxylate superplasticizer. Unfortunately, no efficient production process and equipment suitable for producing polycarboxylic acid water reducing agents with different properties are developed at present.

The preparation method of the polycarboxylate superplasticizer generally relates to a chemical solid-liquid reaction system, and correspondingly comprises a solid-phase and liquid-phase feeding device, a reaction kettle reaction device, a heating device and the like. When the conventional polycarboxylic acid water reducing agent is prepared, the liquid-phase reaction material has good fluidity, and the liquid-phase reaction material is easily added into a reaction kettle by a flowmeter and a pipeline for conveying and feeding. Solid-phase reactant feeding, particularly powder feeding, is difficult to feed into a reaction vessel due to poor flowability of powder, and is usually slowly and manually fed into a reactor after being weighed by metering or fed into the reactor by a belt conveyor or a vacuum feeding device.

In the production process or the design process of the production technology, a plurality of reaction kettles are usually designed and installed in an I-shaped, L-shaped, H-shaped or U-shaped mode, a reaction raw material tank can only be erected right above the reaction kettles for feeding, wherein the discharged materials of reaction solid material tanks can only be transported to one reaction kettle through one belt conveyor, one belt conveyor cannot feed a plurality of reaction kettles, and the problem of difficult feeding of reaction powder occurs. Therefore, the addition of the powder to a plurality of reaction vessels requires a plurality of reaction raw material tanks in cooperation with a plurality of belt conveyors, which complicates the charging system.

Meanwhile, the water reducing agent obtained by the reaction is put into a storage tank, and the water reducing agent in the storage tank is deposited for a period of time to influence the performance of the water reducing agent.

In order to solve the problems, a set of universal and efficient polycarboxylate superplasticizer preparation production system and equipment must be developed by scientific research workers and production technicians, a storage device which is convenient for efficient and accurate feeding, efficient reaction and precipitation prevention can almost meet the production requirements of various polycarboxylate superplasticizer reaction production systems. However, no related report of a set of reaction production system for polycarboxylic acid water reducing agent with universality and high efficiency is found at present.
