A kind of preparation device of heavy metal scavenger

Abstract

The invention discloses a preparation device for a heavy metal scavenger, comprising a reactor body, a reactor cover, an oscillating frame and a controller. The inner chamber of the reactor body is provided with a temperature sensor and a screen is provided near the bottom of the inner chamber. The cover of the reaction kettle includes a cover body and a dilution box. The center of the cover body protrudes to the top to form a convex column. The dilution box is fixed in the central through hole of the convex column. The dilution box is equipped with There is an annular cavity with several stirring balls, the top and bottom of the annular cavity are respectively provided with a liquid channel with a second solenoid valve and a flow meter, and a diluent pipe is inserted into the liquid channel at the top, and the Several raw material pipes are inserted on the top of the annular cavity. By setting up a dilution box as a buffer, the solid raw material and the liquid raw material are firstly diluted with the diluent before being put into the reactor body, so as to avoid direct contact of high-concentration raw materials, which can make The liquid medicine is fully mixed, and the waste liquid can be directly filtered out to retain crystals, which 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 the ...

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
