Technical Field

The invention relates to a pipeline safety device, in particular to a slag falling pipe compensator provided with an alarm device and used for discharging slag of a thermal power plant boiler.

Background

The slag discharged by the power plant boiler is usually discharged into the slag falling hopper through the metal slag discharge pipe, and dust escapes from a gap between the slag discharge pipe and the slag falling hopper during slag discharge, so that the working environment is seriously polluted, and the health of an operator is not facilitated. The invention with the application number of 201110174512.6 discloses a slag dropping pipe expansion joint which is arranged between a vertically arranged slag discharging pipe and a slag dropping pipe and comprises a top plate, a partition plate, a bottom plate, a heat insulation material, a corrugated pipe, an inner pipe and an external connecting pipe. The top plate is serially arranged on the outer wall of the slag discharge pipe and is in sealing connection, the bottom end opening of the slag discharge pipe is exposed out of the through hole of the bottom plate, two end faces of the bottom plate are respectively in sealing connection with the upward inner pipe and the downward slag discharge pipe, and the opposite faces of the top plate and the bottom plate are respectively in sealing connection with the outer connecting pipe and the corrugated pipe to form an elastic compensation structure. The inner cavity of the compensation structure is separated from the slag falling cavity by the partition board, and the flexible heat insulation material is arranged in the inner cavity of the compensation structure, so that the compensation effect of the corrugated pipe is not influenced, and the thermal protection of the corrugated pipe is also formed. The invention adopts a full-sealing structure to connect the slag discharge pipe, no dust escapes when discharging slag, and the working environment is improved. But because the clearance of 2mm ~ 5mm has been reserved between baffle hole and the slag discharging pipe, and the baffle lid constitutes radial floating structure at the inner tube upper end mouth, in the use, the baffle can make radial floating along with the shake of slag discharging pipe to constantly rub inner tube upper end mouth and insulation material, the slag discharging pipe also can rub insulation material in the course of the work, insulation material will be destroyed to powdered and leak from the clearance between baffle hole and the slag discharging pipe, lead to this slag discharging pipe expansion joint's life can not very long.

Disclosure of Invention

The invention aims to provide a slag falling pipe compensator with an alarm device, which is used for solving the problem that dust escapes in the slag discharging process of a thermal power plant boiler and the problem that the slag falling pipe compensator with the alarm device damages a heat insulation material to shorten the service life of the slag falling pipe compensator in the using process.

The purpose of the invention is realized by adopting the following technical scheme: a slag falling pipe compensator provided with an alarm device is arranged between a slag falling pipe and a slag discharging hopper, comprises two sections of corrugated pipes which are mutually connected through a middle pipe, and also comprises a top plate, a bottom plate and a connecting pipe; the top plate and the bottom plate are all circular plate pieces with through holes in the center, a connecting pipe connected with the other end of the corrugated pipe is respectively connected and fixed with the outer peripheral parts of the top plate and the bottom plate to form an inner cavity of the compensator, the inner cavity of the compensator is provided with an inner pipe I, an inner pipe II and an inner ring plate, the diameter of the inner pipe I is larger than that of the inner pipe II, the part of the inner pipe II extends into the inner pipe I, the inner ring plate is arranged between the inner pipe I and the inner pipe II, the upper end of the inner pipe I is fixedly connected with the top plate, the lower end of the inner pipe I is fixedly connected with the outer peripheral part of the inner ring plate, the inner ring plate is not fixed with the outer wall of the middle part of the inner pipe II in a, the inner pipe I, the outer wall of the inner pipe II and the inner wall of the corrugated pipe are provided with heat insulation materials; and the middle pipe is provided with an alarm device.

As a preferable technical scheme of the invention, the outer wall of the connecting pipe is provided with ear plates, and the ear plates are connected by a pull rod. And a reinforcing rib plate is arranged at the joint of the slag falling pipe and the top plate. The slag falling pipe extends out of the bottom end opening of the inner pipe II by more than 50mm, and the vertical section of the slag discharge hopper is larger than 300 mm.

The invention has the beneficial effects that:

1. compared with the prior art, the slag falling pipe compensator provided with the alarm device is arranged between the metal slag discharging pipe and the slag falling hopper, is of a full-sealing structure, has no dust escaping in the use process, and improves the working environment.

2. The corrugated pipe is used as a compensation structure, and the inner ring plate is in contact with the outer wall of the middle part of the inner pipe II but is not fixed, so that the longitudinal compensation and the transverse compensation can be performed.

3. Because a closed cavity is formed among the inner pipe I, the inner ring plate, the inner pipe II, the top plate, the bottom plate and the corrugated pipe, and the heat-insulating material is arranged in the cavity, the defect that the service life of the heat-insulating material is shortened because the heat-insulating material is damaged in the using process of the slag dropping pipe expansion joint with the application number of 201110174512.6 is overcome by adopting the structure.

4. The reinforced rib plate is arranged at the joint of the slag falling pipe and the top plate, so that the slag falling pipe can be fixed, and the slag falling pipe is prevented from swinging greatly due to impact force in the slag discharging process.

5. The outer wall of the connecting pipe is provided with the ear plates which are connected by the pull rod, so that the slag falling pipe compensator provided with the alarm device can be prevented from exceeding the compensation limit and having potential safety hazards.
