Problems solved by technology

However, the pressure filter cavity space of the patented filter press device is fixed, and only the compression stroke of the compression spring is limited, so the squeezing effect on the sludge is limited, thus affecting the final filter press effect

Abstract

The invention relates to the field of environmental protection, in particular to a sludge filter press and a sludge treatment method. The sludge filter press comprises a rack, a filter pressing component, a feeding component, a discharging component and an electric control component, and the filter pressing component comprises a push plate, a thrust plate and multiple filter plate units in series connection, wherein the push plate slides on the rack and serves for compression, the thrust plate is fixed to the rack and matched with the push plate in compression, and the filter plate units are arranged between the push plate and the thrust plate; each filter plate unit comprises metal back plates, piston plates and pressing rings between each back plate and the corresponding piston plate and a spring; multiple filter chambers are formed among the filter plate units, and the filter chambers have the function of changing the chamber sizes under the pressure action of the push plates and the elastic force action of the springs. The metal back plates are longer in service life, meanwhile, the feeding pressure and squeezing pressure can be increased, practical efficiency of equipment is improved, the sludge dewatering effect is enhanced, the usage amount of chemical agents is reduced, and treatment cost per ton of materials is greatly lowered.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a sludge filter press and a sludge treatment method. Background technique [0002] When the sludge is dehydrated and its water content is less than or equal to 50%, the fluidized sludge will become a lumpy sludge with a low water content that is easy to transport, and it is difficult to produce microorganisms and bacteria after dehydration, which will not pollute the environment. Sludge filter press, as a kind of environmental protection equipment, is mainly used in the slag discharge process of sewage treatment. Its main function is to pressurize and dehydrate the sludge with high water content generated in the process of sewage treatment, making it a water content Lower mud cake for easier transport and landfill. For example, CN102126820A discloses a membrane filter press, which adopts a glass-limited reinforced polypropylene membrane filter plate, and injects water int...
