Polycarboxylate superplasticizer production device

Abstract

The invention discloses a polycarboxylate superplasticizer production device, and belongs to the field of building materials. The polycarboxylate superplasticizer production device comprises a raw material bin, the outer end of the raw material bin is in threaded connection with a feeding pipe, and the bottom of the raw material bin is fixedly connected with a guide pie; the electric valves are mounted at the outer ends of the feeding pipe and the guide pipe, the mounting blocks are both fixedly connected to the left and right inner walls of the raw material bin, and the rotating grooves are both formed at the ends, close to each other, of the two mounting blocks; a rotating shaft is fixedly connected between the two inner walls of each rotating groove, a main baffle is rotationally connected to the outer end of the rotating shaft, and two mutually symmetrical torsion springs are fixedly connected between the main baffle and the inner wall of the rotating groove. The containing groovesare formed at the ends, close to each other, of the two main baffles, and the auxiliary baffles are inserted into the containing grooves, so that the raw material bin can be automatically closed after the mercapto ethyl is guided into the raw material bin, the possibility that the mercapto ethyl is decomposed due to illumination is reduced, and accordingly the quality of the produced polycarboxylate superplasticizer is not influenced easily.

Description

technical field [0001] The invention relates to the field of building materials, more specifically, to production equipment for polycarboxylate water reducers. Background technique [0002] Polycarboxylate superplasticizer is a high-performance superplasticizer, a cement dispersant in the application of cement concrete, widely used in highways, bridges, dams, tunnels, high-rise buildings and other projects, the product is green and environmentally friendly, not easy to Flammable and non-explosive, it can be safely transported by train and car. [0003] An invention with the patent number CN201420000926.6 introduces the "Polycarboxylate Superplasticizer Production System", which includes a reaction tank with a fixed mixer, a storage tank connected to the reaction tank, and multiple raw material bins. A composite tank connected to the storage tank, on which a water feeding pipe and a discharge pipe are fixed, the tank wall of the reaction tank is a hollow sandwich structure, ...

Problems solved by technology

[0004] In the above invention, because most of the production raw materials of polycarboxylate superplasticizers are organic compounds, such as mercaptoethane, and the raw material warehouse of this production system cannot be automatically sealed after loading raw materials, after importing mercaptoethane, it may The quality of the produced polycarboxylate superplasticizer is affected by the decomposition of mercaptoethane due to light
