Embodiment Construction
[0023] The present invention will be described in more detail below in conjunction with examples.
[0024] exist figure 1 , 2 Among them, the sealing system of the mechanical rapper is composed of a filter 14, a Y-shaped sealing ring 11, a piston ring 10, an air inlet 6, a lining ring 5, a guide ring 4, and a gas leakage alarm device 7; The transmission rod 2 of the cylinder is connected to the piston rod 3, and the piston rod 3 is connected to the impact rod 15. The filter 14 is installed on the impact rod 15 in front of the piston guide tube 13, and the dust gas in the gasification equipment is After the dust is filtered out by the filter 14, it enters the gap between the piston rod 3 and the piston 9, the piston 9 and the piston sleeve 12 inside the piston sleeve 12 ( figure 1 , the direction of the arrow inside the filter in 2), to ensure that the pressure at the contact position of the impact rod 15 and the piston rod 3 is the same as the pressure in the vaporization eq...

The invention discloses a sealing system of a mechanical vibrator, comprising a filter, a sealing ring mounted on a piston close to one end of a trip rod, a piston ring sleeved on the piston, and guide rings mounted on a piston rod close to one end of a cylinder in a piston guide barrel. A gasket is mounted on the piston guide barrel between two guide rings, the piston guide barrel close to a spring base and a guide ring end is provided with a hole. The hole communicates with exterior of the mechanical vibrator and the interior of the piston guide barrel to form an air inlet communicating with an air source. The advantages of the invention are that the working pressure of a sealing element is reduced and frication between the piston rod and the piston position is reduced, as the sealing system of the mechanical vibrator brings in gas sealing; synchronously, the invention further brings in a gas leakage alarm device and monitors the sealing system of the mechanical vibrator in real time. The integral sealing structure of the system is rationally designed and has low cost. The service life of the sealing element is long and the sealing system is used in the working condition that the mechanical vibrator works at high temperature, under high pressure and with dusty medium.
Description
technical field [0001] The invention relates to a mechanical rapper, in particular to a sealing system of the mechanical rapper. Background technique [0002] In the current industrial production, the mechanical vibrator has been widely promoted and applied because it effectively solves the problem of coal gasification furnace ash accumulation. The operating environment of the mechanical rapper is complex, and the sealing performance of its moving components is very important. The quality of the sealing will directly affect whether the mechanical rapper can run smoothly. The key sealing technology of the mechanical rapper is the piston that transmits the energy of the striking rod. The sealing technology at the circumference of the rod and the piston. In the prior art, the impact rod of the mechanical vibrator and the transmission rod of the cylinder are generally designed as one. The two complete the rapping action through large-scale reciprocating motion. The sealing prob...
