Device for preparing soil heavy metal passivator

Abstract

The invention discloses a device for preparing a soil heavy metal passivator, the structure of the device comprises an electric cabinet, a vacuum pump, a transmission pipe, a waste water tank, a preparation tank and an air heater, the device has the following beneficial effects that a cloth type suction filtration joint consisting of a filter plate and filter cloth is matched with the vacuum pump and the waste water tank for suction filtration; the device can better carry out solid-liquid separation, the filter plate can be detached through rotation, filter cloth is convenient to replace, the device is provided with a stirring device, a hot air temperature measurement air inlet device and all adding ports to be matched with a suction filtration device, integrated preparation and use of the device are achieved, inconvenience caused by repeated manual operation is avoided, and the device is convenient to use. The feeding hopper is arranged at the feeding position of the device to isolate the stirring blade plate and the feeding port, the protection device for automatically powering off when the top cover of the device is opened is matched, the danger of accidental injury caused by stirring is avoided, and after the feeding port is sealed by the tank cover sealing plate of the device, specific ventilation connection can be conducted through the ventilation connector; and the device can be used by connecting an air source in a place where ambient air does not reach the standard.

Description

technical field [0001] The invention belongs to the technical field of devices for preparing soil heavy metal passivators, in particular to a device for preparing soil heavy metal passivators. Background technique [0002] Heavy metal pollution refers to environmental pollution caused by heavy metals or their compounds; it is mainly caused by human factors such as mining, exhaust gas discharge, sewage irrigation, and the use of products with heavy metals exceeding the standard; human activities lead to an increase in the content of heavy metals in the environment, which exceeds the normal range and directly harms the environment. Human health, and lead to the deterioration of environmental quality, and these polluted soils are often treated with corresponding heavy metal passivators for soil restoration. After the soil is mixed, heavy metals can be transformed into forms that are less soluble, less mobile or less toxic, so as to reduce hazards and facilitate soil restoration...

Problems solved by technology

[0004] In order to overcome the deficiencies of the existing technology, a device for preparing soil heavy metal passivating agent is proposed to solve the problem that when the existing technology is used, the passivating agent cannot be compared when the waste water is discharged after the mixed reaction is completed in the production process. The separation of waste water and solids is inconvenient. At the same time, the passivator needs to be manually added, poured and stirred in the production process, which is inconvenient and increases the risk of harm to the staff. And the existing When the technology is used, during the process of mixing and stirring, the addition port can directly contact the inside of the stirring, which is less safe to use. At the same time, the device can only be used in an environment with a specific air index, which is inconvenient.
