A compound polycarboxylate superplasticizer feeding device

Abstract

The invention discloses a compound polycarboxylate superplasticizer feeding device, which includes a supporting platform and a feeding hopper, the small port of the feeding hopper is connected to the supporting platform, and a feeding cover is arranged at the opening of the feeding hopper, and the feeding cover is lifted and lowered. The mechanism is connected with the supporting platform. There is a material partition in the feeding hopper. The center of the material partition is fixedly connected to the round column. The side of the round column is fixedly connected to the inner wall of the feeding hopper. The plate is provided with a discharge port, a first solenoid valve is provided at the discharge port, a feeding device is provided on the upper surface of the feed cover, the middle part of the feed cover is connected to the shaft through the second rotating bearing, one end of the shaft is connected to the motor, and the shaft The other end is clamped with the middle of the round table column; the invention improves the accuracy of feeding, and the feeding control is strict; realizes simultaneous feeding of multiple materials, improves feeding efficiency, reduces the setting of feeding ports in the reactor, and improves airtightness. Sex; Pre-mix the materials to improve the mixing uniformity of the mixture.

Description

technical field [0001] The invention relates to the technical field of water reducer production, in particular to a compound polycarboxylate water reducer feeding device. Background technique [0002] Carboxylic acid superplasticizer is a cement dispersant used in cement concrete, widely used in highways, bridges, dams, tunnels, high-rise buildings and other projects. In order to improve or increase the performance of the carboxylic acid water reducer, it is often necessary to mix the carboxylic acid water reducer with compound materials to prepare a compound polycarboxylate water reducer. The commonly used compound materials are sodium gluconate, paste Essence, air-entraining agent, defoamer, sodium nitrate, inorganic salt, alcohol amine enhancer, etc., will also undergo chemical reactions during the process of mixing and compounding, and the control of the amount of addition is extremely strict. The feeding is not accurate and the control is not strict, so that there will...
