Background

A piston-cylinder device of an electric bag composite horizontal dust remover is used for conveying dust removing gas in a back-blowing dust removing system and controlling the stroke, and comprises a cylinder 1, a hollow piston 2 (a round thin-wall steel pipe with the diameter delta of 3mm and capable of freely moving in the cylinder 1), an elbow I and an elbow II, wherein the air inlet end of the elbow I is connected with a clean flue gas inlet pipe, the air outlet end of the elbow I is fixedly connected with one end of the piston 2, the other end of the piston 2 is inserted into the cylinder 1 from one end of the cylinder 1, a certain gap is formed between the piston 2 and the cylinder 1, the other end of the cylinder 1 is fixedly connected with the elbow II, the air outlet end of the elbow II is connected with an air box 3, the air box 3 moves back and forth along a linear track, and the piston 2 and the cylinder 1 swing by taking the axis of the clean flue gas inlet pipe as the center, as shown in figures 1 and 2.

When the ash removal system of the electric bag composite horizontal dust remover operates, a PLC program detects that the differential pressure of the electric bag dust remover reaches a set value, the ash removal mechanism program automatically operates, the air box 3 starts to move rightwards in a track under the traction action of the transmission device, the air box 3 drives the elbow I and the elbow II to rotate clockwise around respective circle centers while moving, and the piston 2 and the air cylinder 1 synchronously perform reverse movement; on the contrary, when the air box 3 moves to a fixed point, the air box 3 moves in the reverse direction (moves leftwards) and simultaneously drives the elbow I and the elbow II to rotate anticlockwise around respective circle centers, and the piston 2 pipe and the cylinder 1 synchronously move in opposite directions. In the whole process, the elbow I in the piston-cylinder device rotates relative to the elbow II and moves left and right in parallel, but the vertical distance between the elbow I and the elbow II is not allowed to change, at the moment, the piston 2 and the cylinder 1 achieve the purpose of conveying the ash cleaning gas to achieve ash cleaning through contraction or stretching, and in addition, the stroke and the displacement of the piston-cylinder device are controlled through contraction or stretching.

However, the problems of the existing piston-cylinder device are mainly shown in that:

(1) when the piston 2 and the cylinder 1 contract or stretch relatively, because the piston 2 is sleeved in the cylinder 1 without any lubrication, the piston 2 and the cylinder 1 are worn due to long-term operation, the piston 2 and the cylinder 1 are damaged, the ash cleaning gas leaks and the like, and the ash cleaning system cannot work normally;

(2) when the piston 2 and the cylinder 1 move relatively and contract, the end of the piston 2 inserted into the cylinder 1 is easy to jam with the cylinder 1, so that parts are damaged;

(3) in order to ensure the smooth relative movement between the piston 2 and the cylinder 1, a certain gap (such as a gas leakage point shown in fig. 1 and 2) is left between the two components, because the ash removal gas in the gap has certain leakage, 100% of the ash removal gas cannot be ensured to participate in the ash removal process, the energy consumption is too large, and the purposes of energy conservation and consumption reduction cannot be achieved.
