Abstract

The invention relates to the field of pumps suitable for conveying special fluids, in particular to a feeding and discharging plunger pump. The feeding and discharging plunger pump comprises a hydraulic driving assembly and a material conveying assembly; the hydraulic driving assembly comprises a hydraulic cylinder body, a rear end cover, a hydraulic piston and a piston rod, wherein the rear end of the hydraulic cylinder body is connected with the rear end cover, the piston rod is positioned in the hydraulic cylinder body, the tail end of the piston rod is connected with a hydraulic piston, the hydraulic piston is matched with an inner cavity of the hydraulic cylinder body, and a front hydraulic oil injection port is formed in the front end of the side wall of the hydraulic cylinder body;and the material conveying assembly comprises a material cylinder body and a material piston, the material piston is arranged at the front end of the piston rod, the material piston is located in thematerial cylinder body, and a water injection port is formed in the tail end of the side wall of the material cylinder. According to the feeding and discharging plunger pump, the problems that in theprior art, a traditional plunger pump is large in particle size, high in impurity content, high in solid content and poor in liquidity, and in the working process, the temperature of a pump body is high, maintenance is difficult, and the service life of the pump body is short are solved.

Description

technical field [0001] The invention relates to the field of pumps suitable for conveying special fluids, in particular to a plunger pump for feeding and discharging materials. Background technique [0002] In recent years, with the continuous development of society, domestic kitchen waste generated by residential communities, catering centers, farmers' markets, and other municipal entrances has gradually increased. Relevant scientific researchers in my country have done a lot of introduction, absorption, exploration and improvement of domestic waste comprehensive treatment technology , such as dry anaerobic treatment of domestic waste technology as a new technology gradually entered the country and began to pilot construction in some cities. [0003] Although domestic waste classification has been vigorously called for and some results have been achieved in some pilot cities, overall, the organic part of domestic domestic kitchen waste used for anaerobic fermentation is stil...
