Document Type and Number:
WIPO Patent Application WO/2018/082066
Kind Code:
A1
Abstract:
A pipeline diaphragm pump. The pipeline diaphragm pump is provided with a pump housing (10). A cylindrical inner cavity (10A) is formed in the pump housing (10). Multiple arc-shaped pipeline accommodating cavities (10B) are formed in the side wall of the cylindrical inner cavity (10A). An elastic hose (30) is disposed in each of the multiple pipeline accommodating cavities (10B). The two ends of each elastic hose (30) are respectively connected to a liquid input pipe connector (21) and a liquid output pipe connector (22). A one-way valve (40) is disposed at each of the two ends of each elastic hose (30). An inclined offset shaft (50) is disposed in the pump housing (10). The outer portion of the inclined offset shaft (50) is connected to a swing wheel (60) by means of a third bearing (73). A flange (62) is disposed on the outer side of the swing wheel (60) and extends to a position between the elastic hoses (30). When the inclined offset shaft (50) is driven by a motor to rotate, the swing wheel (60) is made to do cone swinging, the elastic hose (30) is extruded or released by means of the flange (62) of the swing wheel (60), and liquid is discharged out and sucked in one direction by means of the one-way valve (40). The pipeline diaphragm pump can be manufactured into a single stage or multiple stages and has the characteristics of being good in liquid flow state, high in work efficiency, convenient to clean and disinfect, long in service life, low in cost, easy to produce and manufacture and the like.
