A belt type sludge dewatering device

Abstract

The invention relates to the technical field of sludge dewatering, and discloses a belt-type sludge dewatering device, which includes a cleaning detection device and a filter belt. The cleaning detection device is composed of a cleaning box and a detection box, and a detection box is fixedly installed on one side of the cleaning box , the filter belt is movably socketed inside the cleaning and testing device, the cleaning box is provided with a belt inlet at one end away from the testing box, and the testing box is provided with a belt outlet at one end away from the cleaning box, and the bottom of the cleaning box has two The side is fixedly installed with a penetrating water inlet pipe, the front and back of the cleaning box are symmetrically fixed with slag discharge pipes, and the bottom inside the cleaning box is movable. The second transmission roller is movable installed, and the top surface of the section of the water inlet pipe located inside the cleaning tank is fixedly installed with a mesh plate. The belt-type sludge dewatering device has good cleaning effect and long service life.

Description

technical field [0001] The invention relates to the technical field of sludge dewatering, in particular to a belt-type sludge dewatering device. Background technique [0002] Nowadays, a lot of sludge is generated in the production process in chemical, pharmaceutical, food and other fields, and the sludge is in a solid-liquid mixed state, which is not convenient to deal with, so it needs to be dehydrated. Belt filter press is very common. A sludge dewatering device, which mainly uses a conveyor belt and a press roller to dehydrate sludge. Although it is widely used now, it still has some problems: [0003] 1. After the belt filter press uses the press roller to filter and dehydrate, some solid sludge remains on the upper and lower filter belts. Although it is scraped off with a scraper, it is simply scraped off the surface, so follow-up needs to be carried out. A filter belt cleaning device is installed, but the existing cleaning device uses a nozzle to directly spray water...

Problems solved by technology

[0003] 1. After the belt filter press uses the press roller to filter and dehydrate, some solid sludge remains on the upper and lower filter belts. Although it is scraped off with a scraper, it is simply scraped off the surface, so follow-up needs to be carried out. A filter belt cleaning device is installed, but the existing cleaning device uses a nozzle to directly spray water on the surface to impact. This method will not be able to clean the inside of the filter belt well due to the impact of direct water spray on the one hand. Sludge, on the other hand, this way of impacting the filter belt will also cause great damage to the filter belt. The filter press itself is filtered by pressing, and then strong water impact will greatly shorten the service life of the filter belt, affecting Dehydration effect and efficiency

[0004] 2. In practice, as the use time increases, the filtering effect of the filter belt will decrease due to the adsorption of sludge. At this time, there is no detection device, which will cause the subsequent sludge to not be effectively dehydrated, and some sludge will not be dehydrated effectively. The dehydration of mud needs to meet the standard. At this time, if the filter belt is not replaced in time, the filtering effect will decrease. Not only does it not meet the requirements, but also needs to be filtered again, which wastes time and reduces the dehydration efficiency.
