[0025] like Figures 1-4 As shown, this embodiment is achieved through the following technical solution: the interior of the silo 1 is provided with a water separation barrier 2 for filtering moisture from ash and slag, and the outer layer of the water separation barrier 2 is also provided with a first spray pipe 4 for rinsing the water separation barrier 2 and a second spray pipe 3 for rinsing the outlet of the silo 1.

[0026] The water separation enclosure 2 includes a connecting ring 201, on which several filter pipes 202 are connected. Gaps are left between the filter pipes 202 for filtering moisture from ash and slag. The connecting ring 201 is connected to an external water source through a pipeline.

[0027] Specifically, the bin body 1 comprises: a shell 101, the inside of the shell 101 is sleeved with a filter cylinder 102; a drainage interlayer 103 is left between the filter cylinder 102 and the shell 101, and a plurality of filter grooves 104 are uniformly arranged on the filter cylinder 102; and the lower edge of the water separation fence 2 is surrounded by the filter cylinder 102.

[0028] The lower edge of the water separation fence 2 is surrounded by the filter cylinder 102, so that the ash is effectively intercepted during the water separation process, and the ash is prevented from directly falling into the drainage interlayer 103.

[0029] Specifically, the water outlet of the filter pipe 202 is arranged in the inside of the filter cylinder 102 to flush the inner wall of the filter cylinder 102.

[0030] Specifically, the water outlet of the filter pipe 202 is in a constricted shape.

[0031] Specifically, the first spray pipe 4 comprises a support frame 401, a plurality of first cleaning pipes 402 are uniformly arranged on the support frame 401, and the water outlet of the first cleaning pipe 402 is provided with a spray head.

[0032] Specifically, the second spray pipe 3 is arranged on the support frame 401, and the water outlet of the second spray pipe 3 is arranged in the drainage interlayer 103 and close to the outlet of the shell 101.

[0033] Specifically, the inside of the water separation fence 2 is further provided with a shunt cap 5 for shunting the ash to the inner wall of the water separation fence 2.

[0034] The shunt cap 5 is arranged in the inside of the water separation fence 2, and the shunt cap 5 is used for effectively guiding the ash entering the water separation fence 2 to the inner wall of the fence, increasing the contact area between the ash and the filter pipe 202, improving the water separation efficiency, and reducing the accumulation of the ash in the center of the water separation fence 2.

[0035] The specific use principle of the utility model is as follows:

[0036] The water separation fence 2 is composed of a connecting ring 201 and a plurality of filter pipes 202, gaps are left between the filter pipes 202, water in the ash is allowed to pass through, and ash particles are left in the inside of the water separation fence 2, and the ash gradually sinks and gathers under the action of gravity.

[0037] The filter pipe 202 is connected with an external water source through the connecting ring 201, when the water source is opened, water flows into the inside of the bin body 1 through the filter pipe 202, the water outlet of the filter pipe 202 is designed in the inside of the filter cylinder 102, the purpose is to flush the inner wall of the filter cylinder 102, and prevent the ash from blocking the filter grooves 104.

[0038] The silo body 1 consists of an outer shell 101 and an inner filter cylinder 102, with a drainage jacket 103 formed between them. This design allows moisture in the ash to continue flowing downwards after passing through the water separation barrier 2 and to be discharged from the silo body along the drainage jacket 103.

[0039] The filtered ash is stored in a container consisting of the water separation enclosure 2 and the filter cylinder 102, and the ash is eventually discharged from the outlet at the bottom of the filter cylinder 102.

[0040] The first nozzle 4 is installed inside the chamber via a support frame 401. The first cleaning pipe 402 and nozzles evenly distributed on it are used to directly rinse the outer surface of the water separation enclosure 2, remove accumulated ash and maintain its filtration efficiency.

[0041] The second nozzle 3 is also installed on the support frame 401, but its outlet is located inside the drainage jacket 103 and near the outlet of the outer shell 101. It is used to flush the drainage jacket 103 and the area near the outlet of the outer shell 101 to prevent ash and slag from clogging the drainage channel.

[0042] After the ash enters the silo 1, the excess water is filtered by the water separation barrier 2 and discharged along the drainage jacket 103. The ash accumulates in the water separation barrier 2 and finally the accumulated ash is discharged from the outlet of the filter cylinder 102. After the ash is discharged, the water separation barrier 2, the first spray pipe 4 and the second spray pipe 3 work together to clean multiple parts of the dewatering silo to ensure the normal operation of the dewatering silo.

[0043] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
