Separation device

Abstract

The invention relates to a mud-water separation device. A drainage groove A which is obliquely formed is formed between every two adjacent filter pressing rollers; the end A of the drainage groove A is correspondingly arranged below a filter pressing roller, and the end B of the drainage groove A is provided with a drainage port for liquid to flow out; the height of the end A of the drainage groove A is larger than that of the end B of the drainage groove A, the groove width of the drainage groove A is matched with the width of the belt surfaces of a filter belt B and a filter belt C, and thedrainage groove A is used for containing water filtered by the filter belt B and the filter belt C at the filter pressing roller above the drainage groove A and guiding the water downwards through thedrainage opening. Liquid collecting units are arranged at the bottom of the rack, correspond to the filter belt A, the filter belt B, the filter belt C and the drainage openings of the drainage grooves A respectively and are used for collecting water filtered by the filter belt A, the filter belt B and the filter belt C and water flowing out of the drainage openings. By means of the arrangement,filtered water can be prevented from flowing to the outer side of the rack in the belt width direction of the filter belts, then water accumulation in a walking area when a worker overhauls equipmentis prevented, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the field of yellow sand production equipment, in particular to a mud-water separation equipment. Background technique [0002] Sand washing is an important process in the production process of yellow sand, that is, by washing the sand raw material with water, the soil is dissolved in water to form muddy water, and then separated from the sand to obtain yellow sand. In order to separate the solid-liquid solid line of mud water produced in the sand washing process, and put the mud with low water content and the separated water separately, the mud-water separation equipment currently used includes a concentration unit and a filter unit. The unit is used for preliminary solid-liquid separation of the muddy water mixed with flocculant, and the filter press unit is used for further squeezing out the water from the muddy-water mixture after the preliminary solid-liquid separation. [0003] Among them, the concentration unit includes...

AI Technical Summary

Problems solved by technology

[0004] However, in the existing mud-water separation equipment, when the filter unit presses the mud-water mixture, a lot of filtered water will flow to the outside of the frame along the width of the filter belt, making it available for maintenance by staff. A large amount of water accumulates in the area where the equipment is walking, which is not conducive to maintenance operations; and the outside of the frame itself along the width of the filter belt is usually equipped with circuits and electrical equipment, so water flowing to the outside of the frame will also bring safety hazards; A large amount of water will accumulate in the outer area of ​​the frame, which will also cause waste of water resources and affect the cleanliness of the production site
