An ice scraping device suitable for high-salt wastewater treatment by cold analysis method

Abstract

An ice-scraping device suitable for cold analysis high-salt wastewater treatment, including a tank body, a round box is arranged in the tank body, the outer circumference of the round box is in sliding contact with the inner circumference of the tank body, and several vertically penetrating holes are provided on the outer circumference of the round box Slide slots, slide bars are installed separately in the slide slots, the slide bars are fixedly installed on the inner wall of the tank body, a first through hole is opened in the middle of the top side of the round box, and the upper end of the inner circumference of the first through hole is fixedly connected to the reciprocating lead screw auxiliary nut. Periphery, the top side of tank body is fixedly installed motor, and the lower end of motor shaft runs through the top wall of tank body and is positioned in tank body, and the lower end of motor shaft is fixedly connected the upper end of reciprocating lead screw auxiliary lead screw. The present invention is simple in structure and ingenious in concept, and is equipped with a filtering device that moves up and down, which can lift the ice crystals in the lower part of the tank body to facilitate the filtering of ice crystals, and can filter the sediments in the upper part to the bottom of the tank body, thereby reducing the precipitation of the sediments along with the tank body. Ice crystal filtration can increase the cleanliness of ice crystals.

Description

technical field [0001] The invention belongs to the field of waste water treatment devices, in particular to an ice-scraping device suitable for cold analysis high-salt waste water treatment. Background technique [0002] At present, the method of condensation and crystallization is usually used in wastewater treatment to separate the water in the wastewater from the pollutants. The ice crystals formed in the process of treating high-salt wastewater by cold analysis are suspended in the upper part of the liquid, so that the ice crystals can be easily filtered out, but the concentrated solution still contains Containing some ice crystals cannot float smoothly, which leads to the continued condensation of ice crystals, so that part of the concentrated liquid is condensed into the ice crystals, causing the ice crystals to contain more impurities in the concentrated liquid. The sediment will be cleaned out with the ice crystals, which will also pollute the ice crystals, and the ...

[0002] At present, the method of condensation and crystallization is usually used in wastewater treatment to separate the water in the wastewater from the pollutants. The ice crystals formed in the process of treating high-salt wastewater by cold analysis are suspended in the upper part of the liquid, so that the ice crystals can be easily filtered out, but the concentrated solution still contains Containing some ice crystals cannot float smoothly, which leads to the continued condensation of ice crystals, so that part of the concentrated liquid is condensed into the ice crystals, causing the ice crystals to contain more impurities in the concentrated liquid. The sediment will be cleaned out with the ice crystals, which will also pollute the ice crystals, and the sediment will easily adhere to the tank wall, causing the reaction tank to be polluted and unable to meet the actual needs. Therefore, we have invented a scraper for high-salt wastewater treatment by cold analysis ice device
