Screw rod drum-type filter press for continuous operation

Abstract

The invention discloses a screw cylinder type pressure filter capable of continuously working, comprising a body, a support saddle for supporting the body, and a driving device. The body is provided with a feeding hole and a discharge hole. The invention is characterized in that the body is a horizontal cylinder body, wherein a screw rod is installed at the shaft line, the screw rod penetrates through the whole cylinder body, the outer diameter of the screw rod is matched with the inner diameter of the cylinder body, the feeding hole and the discharge hole are respectively positioned at both ends of the cylinder body, and simultaneously a drainage mechanism is further provided on the cylinder body; the screw rod is connected with the driving device, the rotation of the screw rod is drivenby the driving device, materials in the cylinder body are transported and dehydrated, and the squeezed water is discharged out of the cylinder body by the drainage mechanism. The pressure filter in the invention not only can realize continuous work of pressure filter for materials, but also can greatly improve the dewatering efficiency of the materials by using higher pressure to press the materials, thereby achieving the purposes of adapting to increasingly-developed industrial production development requirements for large mass and high strength.

Description

technical field [0001] The invention relates to a filter press used for material dehydration, in particular to a screw barrel filter press capable of continuous operation. Background technique [0002] At present, in industry, it is necessary to treat urban sewage and industrial waste water such as chemical papermaking, textile, printing and dyeing, food, leather shoes, pharmaceuticals, ceramics, and various materials for dehydration. The equipment used in the prior art is a filter press, commonly used The preferred filter press is a chamber filter press or a belt filter press. [0003] The chamber filter press is a kind of filter equipment that works intermittently. After each pressing and dehydration process is completed, it must stop for the unloading process. The dehydrated materials are removed from the filter cloth by machinery or manually, and then Repeatedly start a new filter press step, so its production efficiency is very low, and it is difficult to meet the prod...

Problems solved by technology

However, the problems of the belt filter press are: the filter area is small, and it is difficult to use high pressure to press the material. It is still not suitable for the development of modern industrial production with heavy workload and high intensity.

[0005] Moreover, whether it is a chamber filter press or a belt filter press, due to its complex structure, the manufacturing cost is high, which increases the investment cost of the enterprise, and these filter presses occupy a large area
