Abstract

A purging device and an automatic filter cleaning device with the purging device. The purging device comprises a shell (3), a purging mechanism (1), a recycling mechanism (18), and a distributing chamber (12) used for conveying compressed gas to the purging mechanism (1) to purge an object to be cleaned; the purging mechanism (1) comprises a mounting base (2), and the mounting base (2) is rotationally connected to a mounting seat (7) by means of a rotating member (5); and the distributing chamber (12) is further used for conveying the compressed gas to a driving pipeline (8) used for blowing the rotating member (5) to drive the mounting seat (7) to rotate. According to the purging device, the compressed air is conveyed to the driving pipeline by means of the distributing chamber to blow the rotating member to drive the mounting seat to rotate, and meanwhile, the compressed air is conveyed to the purging mechanism to purge said object in cooperation with the distributing chamber, so that the purging efficiency is effectively improved; and impurities such as oil mist generated during cleaning are recycled by means of the recycling mechanism, so that the problems that due to the fact that most of existing filter purging operations adopt manual filter purging, the working efficiency is low, and the working environment is prone to be polluted are solved.

Abstract

The present invention relates to the technical field of dredging engineering machinery, and disclosed is a trailing suction hopper dredger broadside suction port pneumatic sealing apparatus, comprising a slider body, an air cylinder, a piston, end covers, a reset disc spring, and an air seal. The air cylinder is disposed on the side of the slider body facing toward a dredger body; an air inlet is formed at the bottom of the air cylinder; the piston is located in the air cylinder; a boss at the top of the piston faces toward the dredger body; an elastic ring is fixed onto the boss; the inner and outer end covers are fixed to a slider and press both sides of the boss of the piston; several sets of reset springs are located between the inner sides of the end covers and the piston; the air seal is located between the piston and the air cylinder. The advantages of the invention are that: the use of the air cylinder and the piston instead of an airbag avoids the risks of bursting, aging, and mechanical damage of the airbag, and reduces the incidence of failure; the elastic ring has a certain thickness, and the piston stroke compensation margin is sufficient, thereby reducing wear and adapting to relative movement and slight tilt between sealing surfaces to maintain good sealing; and the service life of the sealing apparatus is greatly prolonged.

Abstract

The present invention relates to the technical field of dredging engineering machinery, and provides an airbag sealing device for a side suction port of a trailing suction hopper dredger, comprising a slider body, an airbag cavity, a tongue, a pressing plate, a reverse thrust spring, and an airbag. The airbag cavity is disposed on the side of the slider body towards the hull; the tongue is located in the airbag cavity; a protrusion at the top of the tongue is towards the hull; an elastic ring is fixed on the protrusion; the pressing plate is fixed to the slider and presses two sides of the protrusion of the tongue; the reverse thrust spring is located between the inner side of the pressing plate and the tongue; the airbag is located in a cavity between the tongue and the airbag cavity. The present invention has the following advantages: the elastic ring has a certain thickness and sufficient piston stroke compensation margin, can reduce abrasion, and can adapt to the relative movement between sealing surfaces and slight inclination, thereby maintaining good sealing performance; the airbag does not directly rub against a mud suction pipe, thereby avoiding the risk of machinery damage, reducing the incidence of failures, and prolonging the service life of the airbag; the airbag directly presses against the tongue, thereby ensuring the expansion and contraction reliability of the tongue.
