Tunnel construction wastewater cyclic utilization apparatus

Abstract

The invention discloses a tunnel construction wastewater cyclic utilization apparatus, which comprises a water inlet pipe, a main device, a digital display screen, an operation button, a control cabinet, an apparatus shell, a base, an omnidirectional wheel, a water outlet pipe, and a fixed frame. The main device comprises a driving mechanism, a cam transmission mechanism, a chain wheel mechanism,a sludge removing mechanism, a stay wire transmission mechanism, an alum liquid feeding mechanism, a filter box, a sludge discharge opening, a filter screen, a connection water pipe, an oxidizing box,and a contact-oxidation column. The driving mechanism, the cam transmission mechanism, the chain wheel mechanism, the sludge removing mechanism, the stay wire transmission mechanism, and the alum liquid feeding mechanism are arranged in the main device of the apparatus; sludge on the filter screen can be automatically and periodically cleaned; the filter screen does not need to be replaced manually, and the cyclic wastewater filtering efficiency is improved therefore.

Description

technical field [0001] The invention relates to a tunnel construction waste water recycling device, which belongs to the field of waste water treatment equipment. Background technique [0002] During the tunnel construction process, especially in the tunnel construction section where the surrounding rock joints and fissures are relatively developed and the water inflow from the main tunnel and the horizontal tunnel is relatively large, the amount of tunnel construction wastewater generated is quite large, and the tunnel construction wastewater mainly includes bedrock Fissure water, waste water from drilling rigs, waste water from concrete spraying, pouring and curing, and waste water from washing equipment. During actual construction, if the tunnel construction wastewater is simply discharged, it will not only cause great pollution to the environment, but also cause a lot of waste. Therefore, it is necessary to design a tunnel construction wastewater recycling device with s...

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the object of the present invention is to provide a tunnel construction waste water recycling device to solve the lack of automatic sludge removal mechanism in the tunnel construction waste water recycling device in the prior art, and the device cannot automatically remove the sludge on the filter net. Scraping and removal, tunnel construction wastewater contains a large amount of construction sludge, and a large amount of sludge is intercepted on the filter screen, which requires manual and frequent cleaning of the sludge on the filter screen, resulting in low efficiency of wastewater circulation and filtration
