Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment equipment and relates to an underground domestic sewage treatment device. Background Art

[0002] Metal mines are generally divided into underground mines and open-pit mines. When the burial depth is deep, it is generally chosen to dig tunnels underground to mine ore resources. This is an underground mine. When the burial depth is shallow, it is generally chosen to directly strip the surface soil layer for development and construction. This is an open-pit mine. The vast majority of mines in my country are underground mines. For people working underground, since the distance to go down the mine is too long, their daily life activities are generally carried out underground during working hours. The domestic garbage and sewage generated are mostly difficult to treat. Due to the small space underground, traditional sewage treatment equipment cannot be used for treatment. Usually, the domestic sewage underground is temporarily stored underground and transported out of the mine for treatment regularly. However, sewage is easy to ferment and produce odor during storage underground, polluting the air underground and affecting the health of underground personnel. Utility Model Content

DETAILED DESCRIPTION

[0014] The utility model is described in detail below with reference to the accompanying drawings:

[0015] like Figure 1 As shown, an underground domestic sewage treatment device comprises a bracket 1, a rectangular filter box 2 is arranged on the upper part of the bracket 1, the filter box 2 is used to filter and treat larger impurities in the domestic sewage, a water inlet 3 is formed on the top of the filter box 2, and the domestic sewage can be directly poured into the filter box 2 from the water inlet 3, and a filter screen plate 4 is arranged at an inclined position at the bottom of the filter box 2, and an angle of 30-60 degrees is formed between the filter screen plate 4 and the horizontal plane, and when the sewage passes through the filter screen plate 4, the impurities in the sewage can be filtered out by the filter screen plate 4 is filtered and gathered at the lower end of the filter screen plate 4, the slag outlet 5 is provided at the lower part of the side wall of the filter box 2, the slag outlet 5 is located at the lower end of the filter screen plate 4, a movable door 6 is provided at the slag outlet 5, the filter residue accumulated at the lower end of the filter screen plate 4 can be discharged through the movable door 6, the slag outlet 5 is provided with an inclined slag conveying plate 7, one side of the slag conveying plate 7 is provided with a slag collecting box 8, because the filter screen plate 4 is inclined, after the movable door 6 is opened, the filter residue can slide through the slag conveying plate 7 to the slag collecting box 8 under the action of gravity and be collected.

[0016] A flocculation barrel 9 with an open top is provided below the filter box 2. The flocculation barrel 9 is round. A water pipe 10 is connected to the bottom of the filter box 2. The water pipe 10 is connected to the top of the flocculation barrel 9. The filtered sewage can be input into the flocculation barrel 9 through the water pipe 10 for flocculation, further removing pollutants in the sewage to purify the sewage. Flocculants can be added to the flocculation barrel 9 to remove corresponding pollutants in the water through flocculation to purify the water. The flocculation barrel 9 is provided with a horizontally arranged flocculation removal mesh plate 11 that is compatible with the flocculation barrel. The flocculation removal mesh plate 11 is circular and its diameter is consistent with the diameter of the flocculation barrel 9. The flocculation net plate 11 can move up and down in the vertical direction. A support frame 12 is provided on the top of the flocculation barrel 9. A vertically arranged hydraulic rod 13 is provided on the support frame 12. The bottom end of the hydraulic rod 13 is connected with the middle part of the flocculation net plate 11. The flocculation net plate 11 is passed through the flocculation net plate 11. During flocculation, the hydraulic rod 13 is extended so that the flocculation net plate 11 is located at the bottom of the flocculation barrel 9. After flocculation is completed, the height of the flocculation net plate 11 is raised to fish out the flocs in the flocculation barrel 9, thereby completing the purification of the sewage in the flocculation barrel 9.

The filter residue filtered out by the filter screen plate 4 is gathered at the lower end of the filter screen plate 4. When the water in the filter residue is basically discharged, the movable door 6 can be opened. Under the action of gravity, the filter residue slides through the residue conveying plate 7 to the residue collecting box 8 to be collected. Then, flocculant can be added to the flocculation barrel 9 to flocculate and purify the sewage. After flocculation is completed in the sewage, the height of the flocculation discharge screen plate 11 can be lifted by the hydraulic rod 13 to discharge the flocs from the flocculation barrel 9 to complete the purification of the sewage. Finally, the outlet valve 16 is opened to discharge the sewage into the water bucket 15 through the outlet pipe 14 for collection.

[0020] The sewage after purification can be stored in the bucket 15, and transported out of the well regularly or used accordingly in the well. The use of this device to treat domestic sewage in the well can effectively prevent the sewage stored in the well from polluting the surrounding environment. Compared with conventional water purifiers, it has a large processing capacity and low cost.
