Description

Technical Field

[0001] This utility model relates to the field of slag removal machine technology, specifically to an anti-clogging slag removal machine for a gasifier. Background Technology

[0002] A gasifier converts solid or liquid fuel into combustible gas, which is then mixed with air and burned to achieve heating. Compared to traditional oil-fired furnaces, gasifiers have higher combustion efficiency, save energy, and reduce environmental pollution, and are therefore widely used. To prevent ash and slag produced by the gasifier from clogging the gasifier's discharge port, a slag remover is generally used for slag removal.

[0003] An existing anti-clogging slag removal machine for gasifiers, patent publication number CN219449626U, can screen large and small slag clumps. After screening, the large slag clumps are discharged into the coarse slag chamber, and then the hydraulic telescopic rod drives the pressing block to crush the slag and drop it into the main body of the slag removal machine, thus avoiding large slag clogging the slag outlet.

[0004] However, the ash and slag discharged from the gasifier may contain liquid. The above-mentioned existing technology may discharge smaller ash and slag together with the liquid during ash discharge, which is not conducive to transportation. Utility Model Content

[0014] (III) Beneficial Effects

[0015] In summary, this utility model has at least one of the following beneficial technical effects:

[0016] This anti-clogging slag remover for gasifiers allows ash and slag falling from the gasifier body to enter the slag removal box. Larger ash and slag are crushed by an extrusion assembly and then enters the slag-liquid separation box. A screen separates the ash and slag from the liquid. A cleaning assembly pushes the ash and slag away from the ash and slag outlet. The liquid flows out through the black water outlet pipe when the valve is opened.

The output end of the first motor 13 passes through the protective box 10 and is concentrically connected to one of the rotating rods 11. The output end of the first motor 13 drives the rotating rod 11 located on one side to rotate. The rotating rod 11 drives the rotating gear 12 located on one side to rotate, thereby driving the other rotating gear 12 to rotate in the opposite direction, and then driving the two extrusion rollers 8 to rotate in the opposite direction, so as to extrude the ash and slag into smaller ash and slag, thereby preventing the ash and slag from blocking the ash and slag discharge port 4 due to its large size. An inclined plate 21 is fixedly connected to the slag collection box 2 to facilitate the ash and slag entering the slag-liquid separation box 3.

[0026] Reference Figures 1 to 4The slag-liquid separation box 3 is fixedly connected to the slag collection box 2 and is connected to the slag collection box 2.

[0027] Example 2

[0028] In summary, the working principle and process of the anti-clogging slag removal machine for the gasifier are as follows: During use, the ash and slag falling from the gasifier body 1 enters the slag removal box 2. The output end of the first motor 13 drives the rotating rod 11 located on one side to rotate. The rotating rod 11 drives the rotating gear 12 located on one side to rotate, thereby driving another rotating gear 12 to rotate in the opposite direction. This, in turn, drives the two extrusion rollers 8 to rotate in the opposite direction, compressing the ash and slag into smaller pieces. The ash and slag then pass through the inclined plate 21. Upon entering the slag-liquid separation tank 3, the sieve plate 7 separates the ash and liquid. The electric push rod 15 drives the cleaning plate 16 to move downwards until the cleaning plate 16 contacts the sieve plate 7. The output end of the second motor 20 drives the rotating screw 18 to rotate. The rotating screw 18 drives the threaded block 19 to move. The threaded block 19 drives the sliding plate 14 to slide. By driving the cleaning plate 16 to move through the electric push rod 15, the ash can be pushed away from the ash discharge port 4. The valve 6 is opened, and the liquid can flow out through the black water discharge pipe 5.
