Heavy metal waste liquid disposal equipment for industrial production

Abstract

The invention belongs to the field of waste liquid disposal and particularly relates to heavy metal waste liquid disposal equipment for industrial production. The equipment comprises a box body, a shell, a vertical pipe, a connecting pipe, a piston, a connecting rod, a rotating rod, a bearing, a baffle, an electric push rod, a cross rod, support legs, filter plates, a partition plate, a liquid storage tank, a flow guide pipe, a sealing plug, a fixing rod, a fixing plate, a rotating shaft, a cam, an impeller, a water inlet pipe, a water outlet pipe, a fixing block, a bolt, a clamping block, a gear, a handle and a fixing shaft. According to the heavy metal waste liquid disposal system for industrial production, wastewater and chemicals are discharged into the box body, so that a precipitation reaction of heavy metal in the wastewater is facilitated; by controlling the rotation speed of the cam, control over the putting quantity of the chemicals is facilitated, and the problems that the wastewater disposal effect declines and too many medicaments are put into the box body are avoided. Precipitates are filtered through a filter screen and discharged through the vertical pipe, so that the operation convenience is improved, the cleaning efficiency is improved, and the precipitates are conveniently discharged in time.

Description

technical field [0001] The invention belongs to the field of waste liquid treatment, in particular to a heavy metal waste liquid treatment equipment for industrial production. Background technique [0002] Water resources play an important role in the development of the national economy and social production, and are also an indispensable part of people's lives. However, with the rapid development of industry and agriculture, a large amount of industrial wastewater is discharged, which makes the pollution of heavy metals in water increasingly serious. According to statistics, China About 40 billion tons of industrial wastewater is produced every year, of which heavy metal wastewater accounts for about 60%. These wastewater seriously pollute surface water and groundwater, resulting in a sharp decline in the total amount of available water resources. Heavy metal wastewater generally comes from mining, metal smelting and processing, In industries such as electroplating, tanning...

Problems solved by technology

[0006] The object of the present invention is to provide a heavy metal waste liquid treatment equipment for industrial production in order to solve the above problems. The heavy metal waste liquid treatment system for industrial production is simple in structure and easy to operate. , which is conducive to the precipitation reaction of heavy metals in wastewater, and the speed of cam rotation is beneficial to control the dosage of chemicals, which reduces the difficulty of operation, facilitates control, and is conducive to the proper dosage of chemicals, avoiding the reduction of wastewater treatment effect and To solve the problem of excessive drug delivery, the heavy metal waste liquid treatment system used in industrial production filters the sediment through the filter screen, and the filter plate can be easily replaced through the rotation of the filter plate to avoid blockage of the filter plate, and through the vertical pipe. discharge, which improves the convenience of operation, improves the cleaning efficiency, and facilitates the timely removal of sediment
