Description
Technical Field
The invention relates to the technical field of sludge treatment, in particular to a sludge dryer with a filter pressing device.
Background
The sludge refers to terminal waste of sewage treatment plants and various industries, namely domestic sludge and industrial sludge. The sludge contains a large amount of microorganisms and pathogens, emits foul smell, contains heavy metals, and mainly causes water quality deterioration of water sources and pollutes soil and crops. At present, a multi-purpose sludge dryer is adopted for sludge treatment, and sludge enters the sludge dryer for drying treatment. The sludge is solid sediment produced in the process of water and sewage treatment, the water content of the sludge is different, and part of the sludge contains more water. When the sludge with high moisture is directly put into the sludge dryer for internal treatment without primary dehumidification treatment, more water can exist in the sludge dryer, and the sludge can be treated into a dry state after a large amount of time. Therefore, for the sludge dryer with the filter pressing device, the sludge with higher water content is subjected to dehumidification treatment in advance, and then the sludge treatment speed is improved.
Disclosure of Invention
In order to overcome the defects, the invention aims to provide a sludge dryer with a filter press device, which can improve the sludge treatment speed.
In order to achieve the above purposes, the invention adopts the technical scheme that: a sludge dryer with a filter pressing device comprises a drying box arranged on a frame and used for drying sludge, and further comprises a filter pressing device connected with the drying box and used for preliminarily dehumidifying the sludge, wherein the filter pressing device comprises a dewatering die and a cylinder, the dewatering die is rotatably arranged on the frame and positioned above the drying box, a groove is formed in the dewatering die, a filter plate is arranged in the groove, the filter plate and the inner wall of the groove form a water flowing channel, the water flowing channel is communicated with a water pipe, the cylinder is arranged on the frame, a telescopic rod of the cylinder is connected with a pressing plate, the pressing plate faces the groove, the cylinder can drive the pressing plate to move close to or away from the filter plate, when the sludge is placed on the filter plate, the pressing plate moves downwards along with the cylinder to be in contact with the sludge and extrude water contained in the sludge into the water flowing channel, the wastewater is discharged through the water pipe, after the sludge is preliminarily dehumidified, the pressing plate moves upwards along, after the primarily dehumidified sludge enters the drying box, the dewatering die rotates until the groove faces the pressing plate.
The sludge dryer with the filter pressing device has the beneficial effects that when sludge is treated, the pressing plate faces the groove, the size of the pressing plate is smaller than that of the groove, the sludge is firstly placed on the filter plate in the groove, the pressing plate is driven by the air cylinder to move downwards, the pressing plate is contacted with the sludge on the filter plate and extrudes the sludge, the sludge is tightly positioned between the pressing plate and the filter plate, excessive water in the sludge is extruded out, the sludge flows to a water flowing channel through the filter plate, and the extruded water can be discharged through the water pipe. And after the sludge is extruded, the pressing plate moves upwards to the original initial position along with the air cylinder. At the moment, the dehydration mold rotates to enable the groove of the dehydration mold to face the drying box, so that the preliminarily dehumidified sludge on the filter plate can fall off from the filter plate to enter the drying box due to gravity, and drying treatment is carried out. After the primarily dehumidified sludge enters the drying box, the dewatering die rotates again to enable the groove of the dewatering die to face the pressing plate again. Through this kind of mode, can carry out preliminary hydrofuge to mud, discharge its unnecessary moisture, when reentrant stoving case is dried for the speed that mud was dried at stoving incasement portion has improved sludge treatment speed on the whole greatly.
