Cast-in-situ terrazzo grade level polishing waste slurry recovery device

Abstract

A cast-in-situ terrazzo grade level polishing waste slurry recovery device belongs to the field of environmental protection facilities for building construction. The device comprises a waste slurry collecting tank, a clean water recycling tank and a settling tank. A first overflow port and a second overflow port are arranged on a tank wall, towards the settling tank, of the waste slurry collecting box; a third overflow port and a forth overflow port are arranged on the center of the upper part of a tank wall, towards the clean water recycling tank, of the settling tank; a waste slurry primary filtering mechanism is arranged in a tank cavity of the waste slurry collecting tank; a clean water recycling mechanism is arranged in a tank cavity of the clean water recycling tank; a waste slurry discharge pipe is laid on a building in a polishing place, and a drain outlet of the waste slurry discharge pipe extends to the waste slurry primary filtering mechanism; a clean water conveying pipe is laid on the building in the polishing place; and a pair of filters are arranged between the first overflow port and the second overflow port, and between the third overflow port; and the forth overflow port. The invention has advantages of saving cost, reducing human input for grade level excavation, realizing environmental protection, saving water resources and eliminating secondary pollution of follow-up treatment.

Description

technical field [0001] The invention belongs to the technical field of building construction environmental protection facilities, and in particular relates to a device for recovering waste slurry from polishing of cast-in-place terrazzo floors. Background technique [0002] The cast-in-place terrazzo floor is a composite floor material with cement as the main raw material. It is widely used in hospitals, factories, institutions, schools, commercial places, In buildings such as cultural and entertainment venues, airports, stations and docks, and even canteens. However, in the process of polishing the terrazzo floor (also called polishing in the industry), on the one hand, a large amount of water resources are consumed, and on the other hand, a large amount of waste slurry is generated. If the waste slurry is discharged directly without treatment, it will cause environmental pollution, such as river siltation, municipal facility pipe network blockage, damage to soil and plant...

AI Technical Summary

Problems solved by technology

[0004] There are the following deficiencies in the above-mentioned way of intercepting the waste slurry produced in the grinding process: First, because the waste slurry is directly excavated on the ground by the waste collection pond Collected, and because the waste collection pond excavated directly on the ground has the property of being non-movable and disposable, it is necessary to excavate the waste collection pond when the polishing construction in one place is completed and transferred to another place for construction, resulting in Waste of manpower, financial resources and material resources; Second, due to the large amount of excavation of waste collection ponds and the need for backfilling after the completion of the project, especially permanent pollution of the waste collection pond area will be caused, because the waste collection pond waste site The soil in the place is destroyed, which not only causes waste of labor resources but also produces local persistent pollution; third, because the upper layer of clean water in the waste collection tank cannot be reused for grinding construction, the waste of water resources is serious, which is different from the current society as a whole The energy-conserving and energy-saving economic spirit advocated is contrary to the economic spirit; Fourth, because the sediment accumulated in the waste collection pond needs to be fished out from the waste collection pond after the project is completed or during the grinding construction process, and transported to the environmental protection department. Landfill at the site, or treat it in a specific way, so it not only increases the cost of transportation capacity, but also produces secondary pollution

[0005] From the above description, it can be known that building the waste collection pond directly on the outdoor floor of the grinding construction site is undoubtedly a measure to cure the symptoms rather than the root cause, and so far In the absence of effective countermeasures, there are no other options
