Belt type sludge dewatering device

Abstract

The invention relates to the technical field of sludge dewatering. The invention further discloses a belt type sludge dewatering device. The device comprises a cleaning detection device and a filter belt, the cleaning detection device is composed of a cleaning box and a detection box. The detection box is fixedly mounted on one side of the cleaning box; the filter belt is movably sleeved in the cleaning detection device; a belt inlet is formed in the end, away from the detection box, of the cleaning box. A belt outlet is formed in the end, away from the cleaning box, of the detection box. Through water inlet pipes are fixedly installed on the two sides of the bottom of the cleaning box. Slag discharging pipes are symmetrically and fixedly installed on the front face and the back face of the cleaning box. A first transmission roller is movably installed at the bottom in the cleaning box, second transmission rollers are movably installed on the two sides of the top of an inner cavity ofthe cleaning box, a mesh plate is fixedly installed on the top face of the section, located in the cleaning box, of the water inlet pipe, and the belt type sludge dewatering device is good in cleaningeffect and long in 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.
