The weighing is carried out in the first working chamber 10, and the filtering is carried out in the second working chamber 11. The two processes do not interfere with each other, ensuring the accuracy and efficiency of the operation.

[0037] As Figure 1 , Figure 3As shown in the figure, the weighing unit includes a hook scale 3, a weighing box 30, and a collection box 300.

The sludge sample is put into the weighing box 30 and weighed by the hook scale 3. Water flows into the collection box 300 through the water leakage holes for waste water collection.

[0038] As Figure 1 shown in the figure, the water filtering unit includes an L-shaped plate 4, a rotating shaft 40, and a storage cylinder 400. The L-shaped plate 4 includes a vertical plate and a horizontal plate 41 connected to the vertical plate. The vertical plate is fixedly connected to one side of the top of the second working chamber 11, the horizontal plate 41 is rotatably connected to the rotating shaft 40. There are four storage cylinders 400, and the four storage cylinders 400 are arranged in a circumferential array and connected to the outer wall of the rotating shaft 40. A driving motor 42 is arranged on the top of the horizontal plate 41. The output shaft of the driving motor 42 passes through the horizontal plate 41 and is coaxially fixed to the rotating shaft 40. The output shaft of the driving motor 42 is rotatably connected to the horizontal plate 41.

[0039] As Figure 2 shown in the figure, the bottom wall of the second working chamber 11 is set as an inclined surface, and a water outlet pipe 12 is connected to the side wall of the second working chamber 11. The water outlet pipe 12 is tangent to the inclined surface of the second working chamber 11. The inclined surface design of the bottom wall of the second working chamber 11 enables the filtered water to be discharged smoothly, improving the water filtering efficiency.

[0040] Furthermore, a filter bag (not shown in the figure) is sleeved on the weighing box 30. The filter bag is directly sleeved inside the weighing box 30. During the weighing process of the sludge sample, the filter bag is fixed inside the weighing box 30, and water is discharged through the water leakage holes, which is convenient for the turnover of the sewage sample.

[0044] Working principle:

[0045] The weighing process of the sludge sample: Place the sludge sample in the filter bag, and then place the filter bag in the weighing box 30. There are water leakage holes at the bottom of the weighing box 30. When the water in the filter bag flows slowly or does not flow, weigh it with the hook scale 3 to determine the weight of the sewage sample. To ensure accuracy, four samples with similar weights need to be weighed. During the weighing process, the water in the filter bag flows into the collection box 300 through the water leakage holes, which can avoid the pollution of the sewage sample and the safety risk of the operator;

[0046] The water filtration process of the sludge sample: After weighing, transfer the filter bag to the storage cylinder 400. It is convenient to place and store the filter bag by screwing the cover plate 401. Start the drive motor 42 to drive the rotation shaft 40 to rotate, and then drive the storage cylinder 400 to rotate. The rotation design of the storage cylinder 400 effectively separates the water in the sludge sample and improves the water filtration efficiency. The bottom wall of the second working chamber 11 is set as an inclined surface to facilitate the discharge of the filtered water through the water outlet pipe 12.

[0047] By separating the weighing and water filtration processes of the sludge sample, the utility model effectively improves the efficiency and accuracy of sludge sample dehydration.

[0048] The above are only the preferred embodiments of the utility model, and do not limit the patent scope of the utility model. All equivalent changes and modifications made according to the scope of the utility model should still fall within the scope covered by the utility model.
