Flocculant dosing machine heating device

Abstract

The invention discloses a flocculant dosing machine heating device, which comprises a stirring tank, a dilution pipe, a heating and heat preservation water pipe and a heating hopper, wherein the heating hopper is fixedly connected to one side of the outer wall of the top of the stirring tank through screws, and the heating and heat preservation water pipe is fixedly connected to the outer wall ofthe heating hopper through spiral winding and clamping. According to the invention, a layer of circular water film is formed by water flow sprayed by a spray head of the heating and heat preservationwater pipe, a dry powdery flocculant falls onto the water film from the upper end and falls along with the water film, the powdery flocculant powder is wetted in the process, then enters the stirringtank, and is mixed and dissolved with diluent in stirring tank through stirring of a stirring motor and stirring shaft blades, the flocculant in the heating hopper is preheated through the heating andheat preservation water pipe, warm water sprayed out of the dilution pipe is combined with the flocculant for pre-dissolving, the dissolving speed of the flocculant is increased while the temperatureis controlled to be uniform, raw materials are saved, and the precipitation rate of the flocculant solution is ensured.

Description

technical field [0001] The invention relates to the technical field of flocculant preparation, in particular to a heating device for a flocculant dosing machine. Background technique [0002] The flocculant is mainly a group with positive (negative) charge and some particles or particles with negative (positive) charge in water that are difficult to separate, close to each other, reduce its potential, make it in an unstable state, and use its The aggregated nature allows these particles to be concentrated and separated by physical or chemical means. The flocculation and precipitation method is to use inorganic flocculant (such as aluminum sulfate) and organic anionic flocculant polyacrylamide (PAM) to prepare an aqueous solution and add it to the wastewater, which will produce a compressed double layer and make the suspended particles in the wastewater lose stability. , The colloidal particles coagulate with each other to increase the size of the particles, forming flocs an...

Problems solved by technology

[0004] 1. The heating device of the existing flocculant dosing machine usually directly heats the solution through a heating rod, which easily degrades the flocculant while heating unevenly and affects the settling rate of the flocculant
