Description

Technical Field

[0001] This utility model relates to a boiler, specifically to a biomass boiler ash discharge device with anti-clogging function. Background Technology

[0002] During the operation of biomass boilers, the soot produced by combustion continuously accumulates in the boiler's conveying pipes and ash removal system. Especially after prolonged operation, the accumulation of soot can lead to system blockages. This blockage not only affects the normal operation of the boiler but also reduces its thermal efficiency, increases fuel consumption, and in severe cases, may even lead to boiler shutdown, increasing maintenance and repair costs. Furthermore, most existing ash removal devices use simple mechanical scraping or suction methods, which cannot effectively solve the problem of soot accumulation, resulting in frequent equipment malfunctions. Utility Model Content

[0011] A cleaning sleeve is provided on the inner side of the conveying pipe, and one end of the cleaning sleeve is tapered and contacts the pipe wall of the conveying pipe. The cleaning sleeve and the movable block are attracted by a magnetic structure. The movable block drives the cleaning sleeve to move, thereby scraping the soot on the pipe wall of the conveying pipe to the ash discharge pipe.

[0012] As a preferred technical solution, the magnetic attraction structure includes a magnet disposed on the inner side of the movable block and a magnetic component disposed on the outer side of the dust removal sleeve. The magnetic component is attracted by the magnet, thereby enabling the movable block to drive the dust removal sleeve to move.

[0023] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0024] like Figures 1-3 As shown, the present invention provides a biomass boiler ash discharge device with anti-clogging function, comprising:

[0025] The conveying pipeline 1 has one end connected to the boiler, the other end of the conveying pipeline 1 has a first pipeline 2 installed upwards, and the other end of the conveying pipeline 1 has a second pipeline 3 installed downwards.

[0026] The ash removal structure is installed inside the conveying pipe 1. The ash removal structure scrapes away the accumulated soot inside the conveying pipe 1, thereby achieving the effect of ash removal.

[0027] The first pipe 2 is threadedly connected to a smoke exhaust pipe 4 at one end, and a dustproof net 5 is installed between the smoke exhaust pipe 4 and the first pipe 2 to prevent soot from entering the smoke exhaust pipe; the other end of the smoke exhaust pipe 4 is connected to a flue gas treatment device to treat the flue gas.

[0028] The second pipe 3 is threadedly connected to an ash discharge pipe 6 at one end, and the other end of the ash discharge pipe 6 is connected to an ash collection box for collecting ash.

[0029] The ash removal structure also includes a limiting plate 7 and a movable block 8 installed at the front and rear ends of the conveying pipe 1.

[0030] A threaded column 9 is provided between the limiting plate 7 and the limiting plate 7 via a bearing, and the movable block 8 is movably disposed on the conveying pipe 1 and threadedly connected to the threaded column 9; a drive motor 10 is provided on the limiting plate 7, and the output end of the drive motor 10 is connected to the threaded column 9, so that the drive motor 10 drives the threaded column 9 to rotate, thereby realizing the transmission of the movable block 8.

[0031] A dust removal sleeve 11 is provided on the inner side of the conveying pipe 1, and one end of the dust removal sleeve 11 is tapered and contacts the pipe wall of the conveying pipe 1. The dust removal sleeve 11 is attracted to the movable block 8 by a magnetic attraction structure. The movable block 8 drives the dust removal sleeve 11 to move, thereby scraping the soot on the pipe wall of the conveying pipe 1 to the ash discharge pipe 6.

[0032] In addition, the magnetic attraction structure includes a magnet 12 disposed inside the movable block 8 and a magnetic component 13 disposed outside the dust removal sleeve 11. The magnet 12 attracts the magnetic component 13, thereby enabling the movable block 8 to drive the dust removal sleeve 11 to move.

[0033] In addition, a guide post 14 is provided between the limit plate 7 and the movable block 8 is guided by the guide post 14, thereby ensuring the stability of its transmission.

[0034] For ease of control, this embodiment also includes a control panel, which is connected to control the operation of the drive motor 10. The drive motor rotates, causing the threaded column to rotate, which in turn moves the movable block. The magnetic components are attracted by the magnet on the movable block, thereby enabling the movable block to move the dust removal sleeve.

[0035] The working principle is as follows:

[0036] In the ash removal process, this invention uses a drive motor to rotate a threaded column, which in turn moves a movable block. A magnet on the movable block attracts magnetic components, causing the movable block to move a cleaning sleeve. The cleaning sleeve scrapes away the ash inside the conveying pipe and pushes it into the ash removal pipe for easy ash removal. A dustproof net prevents ash from entering the flue gas pipe, enabling timely and effective ash removal, preventing blockages, ensuring normal boiler operation, improving boiler efficiency, and reducing the frequency of downtime maintenance.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
