AI Technical Summary

Problems solved by technology

[0007] The volume of steel rolling wastewater is large, the content of suspended solids is high, oil, iron sheet, mud and sand are mixed with each other, and the steel rolling wastewater is separated after chemical and physical reactions and magnetization technology. Usually, two sets of equipment are used to complete the process: oil-water separator and inclined plate sedimentation desilter , high equipment investment costs, large floor area, low efficiency, and large maintenance

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 As shown, a kind of inclined plate settler according to the present invention includes a device body 1, an overflow weir 2 is located on the upper part of the device body 1, and an inclined plate area 3 is located on the lower part of the overflow weir 2. Below the inclined plate area 3 is a conical mud collection area 4, a screw conveyor 5 is provided at the bottom of the conical mud collection area 4, and a water inlet 6 is provided on the device body 1 of the inclined plate area 3. One end of the overflow weir 2 is provided with a water outlet 7 and a sampling port 8; the water quality is collected from the sampling port 8 to detect whether it meets the requirements; a manhole is provided on the side wall of the conical mud collection area 4 9. A sludge emptying port 10 is provided at the bottom of the screw conveyor 5 ; a tr...

Abstract

The invention relates to a tilted plate precipitator which comprises a device main body, wherein an overflow weir is arranged on the upper part of the device main body; a tilted plate area is arranged on the lower part of the overflow weir; a tapered mud-collecting area is arranged under the tilted plate area; a spiral conveyer is arranged at the bottom of the tapered mud-collecting area; a water inlet is arranged on the device main body of the tilted plate area; and a water outlet and a sampling port are arranged at one end of the overflow weir. The tilted plate precipitator is excellent in precipitating effect and is conveniently overhauled.

Description

technical field [0001] The invention belongs to water treatment equipment, and is particularly suitable for the separation and treatment of steel rolling waste water, in particular to an inclined plate settler. Background technique [0002] According to the concentration, nature and flocculation performance of suspended particles in water, sedimentation can be divided into the following types. [0003] 1. Free precipitation. The concentration of suspended particles is low, and they are in a discrete state during the precipitation process. They do not adhere to each other, do not change the shape, size and density of the particles, and each completes an independent precipitation process. This type is mostly manifested in the initial stage of grit chamber and primary sedimentation pond. [0004] 2. Flocculation and precipitation. The concentration of suspended particles is relatively high, and coagulation or flocculation can occur during the sedimentation process, so that t...
