Preparation device for heavy metal capturing agent

Abstract

The invention discloses a preparation device for a heavy metal capturing agent. The device comprises a reaction kettle body, a reaction kettle cover, an oscillating frame and a controller; an inner cavity of the reaction kettle body is provided with a temperature sensor, and the place, close to the bottom of the inner cavity is provided with a sieve tray; the reaction kettle cover comprises a cover body and a dilution tank, the center of the cover body extends towards the top to form a convex column, and the dilution tank is fixed in a central through hole of the convex column; and the interior of the dilution tank is provided with an annular hollow cavity with a plurality of stirring balls, the top and bottom of the annular hollow cavity are respectively provided with one liquid passage with one second solenoid valve and one flow meter, a diluent pipe is inserted into the liquid passage located at the top, and a plurality of raw material pipes are inserted into the top of the annularhollow cavity. According to the device provided by the invention, the diluent tank is arranged for buffer, so that a solid raw material and a liquid raw material are firstly diluted by a diluent before being put into the reaction kettle body to avoid direct contact between high-concentration raw materials, the chemical solutions can be fully mixed, a waste liquid can be directly removed through filtration, a crystal can be intercepted, and the device is convenient to use.

Description

【Technical field】 [0001] The invention relates to the technical field of heavy metal scavenger, in particular to the technical field of a preparation device of a heavy metal scavenger. 【Background technique】 [0002] In recent years, due to factors such as the discharge of industrial "three wastes", sewage irrigation, the popularization of pesticides and fertilizers, and the development of the mining industry, the problem of heavy metal water pollution has become increasingly prominent. Water is an essential material for human survival, and its pollution will greatly affect human survival. Heavy metal scavenger is a chemical agent that strongly chelates heavy metal ions. It can chemically react with various heavy metal ions in wastewater at room temperature and within a wide range of pH values, and quickly generate insoluble, low-content water in a short period of time. The amount of water and the flocculent precipitates that are easy to filter and remove, so as to achieve ...

AI Technical Summary

Problems solved by technology

However, the existing reactors are usually only stirred by a stirrer extending into the reactor, and the collision and contact between the raw materials are not sufficient.

In addition, some raw materials need to be diluted before being added into the kettle, and the existing kettle lid only has a material inlet, so the dilution process needs to be carried out in another container, which is troublesome
