The invention relates to a shoe-type squeeze loading device. The device is arranged between a central beam and a shoe plate, and comprises a pressurizing unit and a lifting unit; the pressurizing unitcomprises a hydraulic cylinder; the hydraulic cylinder comprises a cylinder body fixed on the central beam and a piston capable of moving in the cylinder body; the piston is tightly pressed on the boot plate; the lifting unit comprises a lifting rod and an elastic piece sleeved on the lifting rod; the lifting rod penetrates vertically through the cylinder body and the piston and is fixedly connected with the shoe plate; and the elastic piece is fixed between the cylinder body and the lifting rod, and is used to provide an upward lifting force for the piston and the shoe plate. The lifting unit and the pressurizing unit in the device provided by the invention are integrated into a whole, the structure is simple, the installation and maintenance are convenient, and the single elastic pieceis adopted for lifting, so that the single oil cylinder is uniformly stressed, the seal wear of the oil cylinder piston is small, the service life of the oil cylinder piston is prolonged, and meanwhile product quality is greatly improved.
Description
technical field [0001] The invention relates to a shoe press, in particular to a shoe press loading device. Background technique [0002] Shoe press is a wide-area press, which is an important part of the paper machine. Compared with the traditional roll press, this technology is characterized by: higher line pressure, larger dehydration area, longer dehydration time, lower Squeezing specific pressure, low dehydration resistance, so it shows very prominent advantages and advantages in the papermaking process. The paper machine using this technology has high speed, low energy consumption and good quality of finished paper. Shoe press has become the preferred or necessary equipment technology in the speed-up and energy-saving transformation of old paper machines and in the design of new paper machines. [0003] The shoe press loading device is a key component in the shoe press, which provides pressure for the shoe press nip. The traditional shoe press loading device is compo...
