A kind of environmental protection sludge treatment equipment for water conservancy projects

Abstract

The invention discloses an environmental protection sludge treatment equipment for water conservancy projects, which comprises a belt filter press body, a reaction stirring tower is arranged on one side of the belt filter press body, and a mud pump is arranged at the bottom of the reaction stirring tower , one side of the mud pump is provided with a clean water tank, the top of the belt filter press body is provided with a water pump, and one side of the water pump is provided with a distributing device. In the present invention, the impurities in the sludge are broken and intercepted by the crushing roller row and the filter frame, and are homogeneously dispersed by the distributing roller and then smoothed by the pressing plate, gathered and transported to the top of the second conveying pressing belt, and made under the action of the shaking device It is paved inside the distribution trough, the first press belt and the second press belt cooperate with the compacted mud to squeeze out the water, cooperate with the hot air blower to improve the sludge treatment efficiency, reduce the adhesion of impurities, and scrape the material after extruding the mud cake Scraping and crushing mud cake, the device has high working efficiency, can ensure the uniform pressure filtration of sludge, squeeze out water to the greatest extent, and reduce the loss of the device.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering sludge treatment, in particular to an environmental protection sludge treatment equipment for water conservancy engineering. Background technique [0002] The sludge of water conservancy projects needs to be treated. Due to the high water content of the sludge, the sludge is bulky, which is not convenient for transportation and treatment, and the sludge containing a large amount of water is easy to rot and smell, which leads to secondary pollution. Therefore, Usually dehydration is required. The sludge after dehydration treatment can not only greatly reduce the cost of transportation and treatment due to the reduction of water content and volume, but also increase the content of available substances in the sludge after thickening. [0003] At present, the mechanical dehydration method is a widely used dehydration technology. The commonly used dehydration machines include vac...

AI Technical Summary

Problems solved by technology

When the existing belt filter press is working, if the soil cannot be effectively homogenized, the dehydration effect will be seriously affected. The large solid impurities contained in the sludge will form a support during the filter press, which cannot be effectively filtered, or even It will damage the device and reduce its service life, and the sludge is easy to compact. If the filter cannot be pressed in time or the filter is not spread evenly, the water in the sludge cannot be effectively squeezed out.
