When the smoke dust recovered in the dust collection pipeline needs to be sent into the smoke dust tank, the conveying pipeline and the interface part of the smoke dust tank need to be connected in a seamless mode in order to prevent the smoke dust from leaking into the air when falling; when the smoke dust storage amount in the smoke dust tank is full and the smoke dust tank needs to be moved away for discharging, a certain gap needs to be formed between the conveying pipeline and the smoke dust tank. The blanking expansion piece in the prior art mainly comprises an expansion piece upper body 1, a telescopic driving cylinder 2, a corrugated expansion pipe 4, a lower body sealing ring 6, an expansion piece lower body 9, a smoke inlet 11, a motion guide mechanism 15, a connector 16 and other main parts. The structure of the blanking expansion piece in the prior art causes the following defects: 1. the flap valve is not closed tightly, and meanwhile, the recovered smoke dust is bonded on the flap valve, so that the smoke dust is required to be cleaned at any time when the smoke dust tank 8 is moved away; 2. the existence of the motion guide mechanism 15 ensures that the smoke dust can 8 is placed to be vertical to the lower end face of the telescopic device, otherwise smoke dust is easy to leak from the interface of the blanking telescopic device and the smoke dust can 8, and environmental pollution is caused; 3. the position of the smoke outlet 7 in the expansion piece is higher than the opening of the smoke tank 8, so that the smoke falls into the smoke tank 8, and the generated smoke is accumulated on the wave table of the corrugated expansion pipe 4, thereby causing the expansion difficulty of the corrugated expansion pipe 4.

Disclosure of Invention

An object of the utility model is to provide a be provided with flexible pipe, omit guide arm motion guiding mechanism's a telescoping device for flue gas is gathered dust simultaneously.

The design idea of the invention is that the spherical joint is connected with the lower body of the expansion piece, so that the movement of the lower body of the expansion piece is not limited by the directionality of the piston rod of the cylinder, the inlet end surface of the smoke dust tank does not need to be perpendicular to the pipeline of the blanking expansion piece, and the sealing performance of the interface is enhanced. The designed structure cancels a motion guide mechanism, reduces the requirement on synchronism among the driving cylinders, and has more reliable working performance. Meanwhile, a soft blanking cover is additionally arranged in the design, so that the falling control length of the smoke dust is increased to the inlet of the smoke dust tank, the possibility and the quantity of the smoke dust falling to the step part of the telescopic corrugated pipe are reduced, the working distance of the telescopic corrugated pipe is kept, and the service life is prolonged.

In order to achieve the above purpose, the technical scheme of the utility model is that:

the utility model provides a telescopic ware for flue gas is gathered dust, includes the telescopic ware upper part of the body, drives actuating cylinder, ball joint, the flexible pipe of ripple, flexible pipe, lower part of the body sealing washer, smoke and dust jar, the telescopic ware lower part of the body, cylinder piston rod, flue connecting piece, telescopic ware and cylinder mounting bracket, the telescopic ware be equipped with the flue connecting piece at the top of telescopic ware upper part of the body, the telescopic ware is equipped with at the middle part of telescopic ware upper part of the body, flexible pipe is equipped with to the lower part of the telescopic ware, the flexible pipe of ripple is equipped with to the outside suit of telescopic ware, the cylinder mounting bracket is equipped with on the telescopic ware upper part of the body, the symmetrical actuating cylinder that drives being equipped with on the cylinder mounting bracket, the ball joint is equipped with to the tip of the cylinder piston rod that drives on.

Compared with the prior art, the utility model discloses an actively the effect does:

1. the telescopic device adopts the spherical joint to connect the lower body of the telescopic device, so that the movement of the lower body of the telescopic device is not limited by the directionality of the piston rod of the cylinder, the inlet end surface of the smoke dust tank does not need to be perpendicular to the pipeline of the blanking telescopic device, and the sealing performance of the interface is enhanced;

2. the telescopic device cancels a motion guide mechanism in the structure, reduces the requirement on the synchronism among the driving cylinders and ensures that the telescopic device works more reliably;

3. the blanking cover made of the flexible conduit is added in the expansion piece, so that the falling control length of the smoke dust is directly increased to the inlet of the smoke dust tank, the possibility and the quantity of the smoke dust falling to the step part of the corrugated expansion pipe are reduced, the working distance of the corrugated expansion pipe is kept, and the service life of the corrugated expansion pipe is prolonged;

4. because the telescopic device simplifies the telescopic device composition mechanism, the use cost and the maintenance cost of the telescopic device are reduced.
