Embodiment Construction

[0019] The present invention will be described in detail below in combination with specific embodiments.

[0020] Such as figure 1 , 2 As shown in and 3, the dust-containing slag-slurry sewage enters the tank body 1 through a slurry pump and an electric valve. 1. Its tangential impulse makes the sewage entering the tank 1 rotate along the inner wall of the tank 1, so that the large particles in the water settle quickly. In addition, after the sludge and sewage are filtered through the filter cartridge 12 of special material, the clean water passes through the back pressure chamber 13 and Drainage pipe 15 gets back to the clean water storage tank and then gets back to the operating system for reuse. The inner and outer mesh cages of the filter cartridge are subjected to a pressure of about 0.3Mpa, and the filter bag shrinks and clings to the inner mesh cage; when a certain thickness of sludge layer accumulates on the outer wall of the filter cartridge, the water inlet pressur...

Abstract

The invention provides a comprehensive treatment, filtration and recovery device for mud sewage. The comprehensive treatment, filtration and recovery device comprises a sewage comprehensive filtration and sedimentation device tank body, a spiral feeding conveyer and a double spiral impeller conveying and feeding machine; the tank body comprises a water inlet, a filter cartridge, a back pressure chamber for flushing, a sealing cover, a clear water discharging hole, an access hole and a steel structure system; at the bottom of the tank body, mud is conveyed to the spiral feeding conveyor or a mud conveying pipeline at the lower side through the double spiral impeller conveying and feeding machine and is recovered. In the traditional mud conveying, a sedimentation tank is generally adopted for sedimentation, and the mud is discharged by grabbing with a crane; or the mud in a sedimentation pool is pressurized and conveyed to other users through a pipeline, a mud pump and a pipeline. Such an operating manner is complicated in process, large in occupied space, resulted in secondary pollution, high in investment and energy consumption, poor in filtrate quality, poor in mud concentration effect and difficult in treatment. According to the comprehensive treatment, filtration and recovery device provided by the invention, after all the mud is subjected to suspension, refined filtrating, dehydration and concentration, filtered clear water can be reused as reclaimed water or recycled to realize zero emission.

Description

technical field [0001] The patent of the present invention relates to a comprehensive filtration and reuse device for various wet treatment of sludge recovery and sewage treatment, which belongs to the technical field of environmental protection and resource recovery and reuse. Background technique [0002] Metallurgical enterprises such as iron and steel industry need to carry out wet dust removal and slurry conveying and recovery operations in the process of converter blowing. In the foundry industry, wet shakeout dust removal and casting cupola slag wet granulation will produce a large amount of mud slurry. Traditional mud transportation generally uses sedimentation tank cranes to grab and discharge mud or sedimentation tanks are sent to other users by pipelines, mud pumps and pipelines. This method of operation has a complicated process, takes up a lot of space, causes secondary pollution, requires a lot of investment, and is not easy to manage. Contents of the inventi...
