Description
Technical Field
The utility model relates to the technical field of dust remover equipment, in particular to an anti-blocking device for an ash bucket of a dust remover.
Background
The cloth bag dust remover has the function of purifying the flue gas and filtering out solid particles and dust in the flue gas. After the semi-dry flue gas treatment process, flue gas needing purification treatment enters a dust remover along the inlet of each bin. The filtration process is mainly carried out on the outer surface of the cloth bag, and solid particles are trapped and coalesced into blocks on the outer surface of the filter bag. Heavy particles settle to the dust hopper of the dust remover under the action of gravity. The solid ash which is agglomerated into blocks is removed in the cloth bag cleaning process and falls to the bottom of the ash bucket.
As shown in fig. 1 and 2, the dust hopper 1 of the dust remover is of a prismatic table structure with a square or rectangular cross section and a wide upper part and a narrow lower part, dust enters from the top inlet 1-1 and is discharged from the bottom outlet 1-2. Because the ash bucket 1 is of a prismatic table structure with a wide upper part and a narrow lower part, the side wall is of an inclined shape, dust can be deposited on the side wall of the ash bucket in the using process, and in order to prevent dust deposition or aggregation hardening after long-time use, each ash bucket is provided with a blocking preventing device.
The application number of the picture is as follows: the electromagnetic pulse valve mounting structure for bag house dust collector disclosed in CN201420613555.9 is described.

When the ash bucket needs to be cleaned, the electromagnetic pulse valve 3 drives compressed air, and the interior of the ash bucket is sprayed and cleaned through the spraying pipe 4. However, because the blowing coverage area at the bottom of the blowing pipe 4 is small, only dust on the side wall of the blowing pipe at the bottom of the blowing port can be cleaned, and the ash cleaning effect is poor; and a plurality of anti-blocking devices are arranged on the ash bucket 1, so that the cost is increased.

Detailed Description
As shown in figures 3 and 4, the ash bucket anti-blocking device of the dust remover comprises an air bag 2, an electromagnetic pulse valve 3, a blowing pipe and a vibrator 7 which are arranged on an ash bucket 1.
In this embodiment, the air bag 2 is horizontally installed outside the ash bucket 1 by the air bag installation frame 2-1. The blowing pipe includes: the main pipe 5 and the branch pipe 6, one end of the main pipe 5 is communicated with the air bag 2 through the electromagnetic pulse valve 3, the other end of the main pipe passes through the side wall of the ash bucket 1 after being sealed, and the main pipe is horizontally arranged on the side wall of the inner cavity of the ash bucket 1 through the main pipe bracket 5-1.
In the utility model, the number of the 5 main pipes communicated with the same air bag 2 is more than 1; only one main pipe 5 is arranged on the side wall of the same ash bucket 1. In this embodiment, two main pipes 5 are connected to the same air bag 2, so that the cost of the overall structure is reduced. In this embodiment, the air bag 2 and each main pipe 5 are not located on the side wall of the same ash bucket 1, i.e. two main pipes 4 are located on the opposite side walls of the two ash buckets.
Because the inner cavity of the ash bucket 1 is of a prismatic table structure with a wide upper part and a narrow lower part, once dust accumulated on the inner wall of the ash bucket is hardened, the bottom with a smaller size is easier to be blocked, so that the distance between the main pipe 5 and the inlet of the ash bucket 1 is greater than one third of the height of the ash bucket 1, and the ash is mainly removed from the lower half part of the inner cavity of the ash bucket 1. Meanwhile, the length of the branch pipe 6 is smaller than the distance between the main pipe 5 and the outlet of the ash bucket 1, so that ash removal operation can be carried out on the part between the ash bucket outlet 1-2 and the main pipe 5.
The pipe body of the main pipe 5 is provided with air nozzles (not marked in the figure), and the number of the air nozzles is more than 2; each air jet is provided with one branch pipe 6, one end of each branch pipe 6 is communicated with the air jet, the other end of each branch pipe is obliquely downwards arranged along the angle of the side wall of the ash bucket 1, and the branch pipe is fixed on the side wall of the ash bucket based on the branch pipe mounting frame 6-1. In the utility model, each main pipe 5 can drive a plurality of branch pipes 6, namely, the side wall of the ash bucket is provided with a through hole for installing the main pipe, so that the ash bucket can be supported to be subjected to air injection and ash removal through the branch pipes. The number of the specific air nozzles and the number of the branch pipes 6 are adaptively adjusted according to the size of the ash bucket. In this embodiment, 3 air nozzles are uniformly arranged at the bottom end of the main pipe 5, and each air nozzle is provided with a branch pipe 6 to ensure that the side wall where the main pipe 5 is located can be subjected to uniform ash removal operation.
In order to cover areas with different heights on the side wall, the lengths of the branch pipes 6 communicated with the same main pipe 5 are different, so that the ash removal is ensured to be carried out on the different areas on the side wall where the main pipe 5 is positioned, and the ash removal effect is improved.
In order to further improve the ash removing effect, blowing openings (not marked in the figure) are arranged at different angles and length positions on the pipe body of the branch pipe 6 in the ash removing area.
In order to further improve the ash removal effect on the inner cavity of the ash bucket, the pneumatic vibrator is arranged on the inner wall of the ash bucket to cooperatively operate with the air injection ash removal. In order to reduce the overall cost while maintaining the ash removal effect, the vibrator 7 is disposed on different side walls of the hopper 1 so as to intersect with the main pipe 5.
After the technical scheme of the utility model is used, the main pipes in the blowing pipe are distributed on two sides of the inner wall of the ash bucket, and a plurality of branch pipes are distributed downwards along the wall of the ash bucket, so that the blowing ash cleaning coverage area is effectively increased, and the cleaning effect on hardened materials in the ash bucket is obvious. Meanwhile, the pneumatic vibrator is matched, so that the ash cleaning effect inside the ash bucket is further enhanced.
