DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 As shown, the utility model provides the following technical solutions:

[0022] A sludge dewatering device comprises a device box 1, to which a sludge main pipeline 2 is fixedly connected, a main pipeline valve 4 is installed at the feed end of the sludge main pipeline 2, and a plurality of sludge branch pipelines 3 are fixedly connected to one side of the sludge main pipeline 2, the sludge main pipeline 2 and the sludge branch pipelines 3 are both made of stainless steel, branch pipeline valves 5 are arranged between the plurality of sludge branch pipelines 3 and the sludge main pipeline 2, a water distribution plate 8 is installed between the liquid outlet ends of the plurality of sludge branch pipelines 3, a filter bag 6 is installed at the bottom of the water distribution plate 8 to prevent the water column from directly impacting the filter bag 6, the filter bag 6 is a degradable fiber filter bag, which can filter evenly and improve the filtering effect, and a plurality of base feet 12 are fixedly connected to the bottom of the device box 1.

[0023] Through the above technical solution, when personnel need to filter the sludge, the pipeline for conveying the water-containing sludge is connected to the main pipeline valve 4, the main pipeline valve 4 is opened, the water-containing sludge flows into the sludge main pipeline 2, and then the branch pipeline valve 5 is opened, and the water-containing sludge is conveyed through the sludge branch pipeline 3, so that the water-containing sludge flows into the water distribution plate 8, and the water is distributed through the water distribution plate 8, so that the water-containing sludge evenly impacts the filter bag 6, and the mud and water are separated by the filter bag 6 under the action of gravity, and the dehydrated sludge remains in the filter bag 6, and the water seeps to the bottom of the filter bag 6.

[0024] Specifically, in one embodiment, regarding the device housing 1:

[0025] like Figure 3-Figure 4 As shown, a filter bag back support 10 is fixedly connected to the inside of the device box 1, and the filter bag back support 10 is located on one side of the filter bag 6.

[0026] In this embodiment, the filter bag 6 relies on the filter bag back support 10 to form a 75° backward tilt with the ground, and muddy water is flushed onto the entire filter bag 6 through the water distribution plate 8, which has a better actual effect than vertical.

[0027] In addition, in the present invention, in order to facilitate the maintenance of the device, as Figure 1 As shown, a detachable shutter 11 is installed on the device box 1.

[0028] Furthermore, in the present invention, after the device filters the sludge, in order to collect the water generated during the filtration, as Figure 3-Figure 4 As shown, a water collecting pool 7 is installed inside the device housing 1 , the water collecting pool 7 is located below the filter bag 6 , and the top of the water collecting pool 7 is sunken to form a liquid storage chamber 16 .

[0030] In order to facilitate the discharge of water in the water collection tank 7, a drain outlet 9 is installed on one side of the water collection tank 7. After the water collection tank 7 collects sewage, the sewage is discharged through the drain outlet 9, making it easier to collect the sewage.
