When the filter material needs to be squeezed and dewatered, the air cylinder drives the squeezing roller to be close to the driving roller and adjusts the gap between the squeezing roller and the driving roller; when the filter material does not need to be squeezed and dewatered, the air cylinder drives the squeezing roller to be far away from the driving roller.
Further comprises the following steps: and a driving gear is fixedly arranged at one end of the driving roll, a synchronous gear is fixedly arranged at the position, corresponding to the driving gear, of one end of the pressing roll, and the synchronous gear is meshed with the driving gear. When the squeezing roller needs to be synchronous with the driving roller, the cylinder drives the squeezing roller to be close to the driving roller and enables the synchronous gear to be meshed with the driving gear; in addition, the distance between the press roll and the drive roll can be finely adjusted while ensuring the meshing of the synchronizing gear and the driving gear.
Further comprises the following steps: the negative pressure suction port is arranged on a hollow round pipe, the hollow round pipe is horizontally arranged, and the negative pressure suction port is arranged along a bus of the hollow round pipe and is positioned at the top of the hollow round pipe. The hollow circular tube has better supporting effect on the filter material.
Further comprises the following steps: automatic deviation correcting rollers are arranged on two sides of the air knife dehydration device and are mounted on the rack, and the lower acting point of the automatic deviation correcting rollers and the negative pressure suction port are located on the same horizontal plane. The filter material passes through the automatic deviation correction roller, the air knife, the negative pressure suction port, the air knife and the automatic deviation correction roller in sequence, and then the dehydration and moving effects of the filter material are guaranteed.
The utility model has the advantages that: the extrusion dehydration device, the air knife dehydration device and the negative pressure dehydration device are creatively combined together, so that a plurality of dehydration modes can be combined for use, and the dehydration requirements of filter materials with various specifications are met; the air knife dehydration device adopts two air knives, and a negative pressure suction port is matched between the two air knives, so that an effective distance is kept between the filter cloth and the air knives, and the dehydration effect is ensured; set up automatic deviation correcting roller in air knife dewatering device's both sides, guarantee the filter media level through the rate of tension of air knife dewatering device and negative pressure dewatering device and filter cloth to promote the dehydration effect of filter media.
