High-efficiency dewatering machine provided with filtering screen and utilizing strong spiral force for extrusion

Abstract

Disclosed is a high-efficiency dewatering machine provided with a filtering screen and utilizing strong spiral force for extrusion. The high-efficiency dewatering machine is composed of a fixing plateand bracket, a perforated casing pipe, the filtering screen, an auger, a feeding pipe, a blind plate and bearing base and a speed reducer; the filtering screen is arranged on the inner wall of the perforated casing pipe and tightly fits the inner wall; a flange at one end of the perforated casing pipe is fixedly provided with the fixing plate and bracket through screws; a fixing plate at the outer end of the fixing plate and bracket is provided with an adjusting screw; a flange at the other end of the perforated casing pipe is fixedly provided with the blind plate and bearing base through a screw; the perforated casing pipe is internally provided with the auger, and the auger is fixed through a bearing of the blind plate and bearing base; the outer end of the auger is connected with the speed reducer through the flange; the feeding pipe is arranged at the outer side, close to the blind plate and bearing base, of the perforated casing pipe. According to the high-efficiency dewatering machine, filtering is conducted through strong-force pushing of the auger and compression of a screw rod jacking cover, the pressure is 1 Mpa / cm<2> or above, various water containing substances such assewage sludge and oil sludge are strongly pressed for dewatering, the dewatered sewage sludge is discharged through the gap between the auger and a screw rod jacking plate, the efficiency is high, and the labor is saved.

Description

technical field [0001] The invention relates to the field of environmental protection and chemical industry, in particular to a high-efficiency dehydrator which is provided with a filter screen and utilizes spiral forceful extrusion. Background technique [0002] Domestic, industrial sludge, oil sludge and other sludge with high water content have been equipped with equipment of various structures, most of which are plate and frame filter presses. This type of equipment belongs to intermittent filtration, which is laborious to operate and low in efficiency; The structure of type filtration can realize continuous operation, however, the dehydration rate is low due to problems such as low pressure. At present, the water content of domestic sludge after dehydration by belt dehydrators is generally still around 75-80%. Therefore, it is necessary to invent a continuous and efficient dehydration equipment. Contents of the invention [0003] The object of the present invention ...
