Description

Technical Field

[0001] The invention relates to the technical field of coal mine drainage, in particular to a negative pressure sedimentation box for sludge filtering. Background Art

[0002] Flooding in coal mines is one of the five major natural disasters in coal mines (water, fire, gas, coal dust, and roof). If the accumulated water is not discharged in time, it will pose a great threat to the safe production of the entire coal mine. Effective drainage measures can keep the workplace in the mine safe and dry, solve the problem of accumulated water, thereby effectively improving the work efficiency of miners and making the entire production process smoother.

[0003] At present, in order to avoid blockage in underground drainage, a sedimentation box is used to filter and settle the muddy water before discharging it; however, in actual application, due to the large amount of impurities such as mud residue in the muddy water, the filter box needs to be taken out and cleaned after each sedimentation, which makes its operation very cumbersome. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a negative pressure sedimentation box for sludge filtration, which drives a sludge sweeping plate to slide along the inclined bottom surface of the filter box toward the sludge storage tank. The sludge sweeping plate can fit the bottom surface of the filter box and sweep all the precipitated sludge into the sludge storage tank, so that the overall filtration effect is better. Therefore, each time the cleaning is completed by only operating the sludge sweeping plate. Compared with the traditional method of taking out the filter box to clean the sludge, the operation is simpler.

[0005] To solve the above technical problems, the technical solution of the present invention is achieved as follows:

[0008] The filtering part includes a filter box fixed on the bracket, and a plurality of filter holes are opened on the left side, bottom side and right side side of the filter box; the bottom side of the filter box gradually slopes down from the water inlet to the drain outlet; the two corners of the filter box near the water inlet are concave slag storage tanks, and a vertically arranged slag sweeping plate is installed inside the filter box, and the two sides of the slag sweeping plate are respectively slidably installed in the slideways on the side walls of the filter box;

[0009] When the slag sweeping plate is driven to slide along the inclined bottom surface of the filter box toward the slag storage tank, the slag sweeping plate can fit the bottom surface of the filter box and sweep all the precipitated mud into the slag storage tank.

[0010] By adopting the above scheme, the sludge filtering negative pressure sedimentation box drives the sludge sweeping plate to slide along the inclined bottom surface of the filter box toward the sludge storage tank. The sludge sweeping plate can fit the bottom surface of the filter box and sweep all the precipitated sludge into the sludge storage tank, so that the overall filtering effect is better. Therefore, each time you only need to operate the sludge sweeping plate to complete the cleaning. Compared with the traditional method of taking out the filter box to clean the sludge, its operation is simpler.

[0011] As a preferred embodiment of a negative pressure sedimentation box for sludge filtration, vertically arranged sleeves are fixed to the tops of both ends of the sweeping plate, and a movable sliding handle is slidably installed in the sleeve; the movable sliding handle is an L-shaped handle, and the movable sliding handle extends all the way to the outside of the sedimentation box.

[0012] By adopting the above scheme, in order to facilitate the sliding of the slag sweeping plate, the movable sliding handle is operated to guide the sliding of the slag sweeping plate, and the slag sweeping plate is driven to slide along the inclined bottom surface of the filter box toward the slag storage tank. The slag sweeping plate can fit the bottom surface of the filter box and sweep all the precipitated mud into the slag storage tank, and then clean it when the slag storage tank is full.

[0013] As a preferred embodiment of a sludge filtering negative pressure sedimentation box, a gate is also installed at the slag storage tank, and the two sides of the gate are slidably installed in a slide groove fixed on the filter box, and the gate can be opened by sliding the gate upward; a vertically arranged fixed sliding handle is fixed to the top of the gate; the fixed sliding handle is an L-shaped handle, and the fixed sliding handle extends all the way to the outside of the sedimentation box.

[0014] By adopting the above scheme, in order to facilitate the cleaning of the mud residue in the slag storage tank, the gate is guided to slide upward by operating the fixed sliding handle, so as to open the gate and clean the mud residue.

[0015] As a preferred embodiment of a negative pressure sedimentation box for sludge filtration, the surfaces of the sludge sweeping plate and the gate are provided with filter holes of the same size as the filter box.

[0016] In order to prevent the slag sweeping plate and the gate from affecting the filtering effect, filter holes are also opened on the surface of the slag sweeping plate to improve the smoothness of the filtering.

[0017] As a preferred embodiment of a negative pressure sedimentation box for sludge filtration, the sedimentation box is further provided with a cleaning channel at the location of the sludge storage tank, and a cover plate is sealed at the opening of the cleaning channel; the bottom of the sludge storage tank is flush with the bottom of the cleaning channel.

[0018] By adopting the above scheme, in order to facilitate the cleaning out of the mud residue, the mud residue in the slag storage tank can be completely cleaned out by opening the cover plate and the gate.

[0020] By adopting the above scheme, in order to achieve negative pressure water delivery, the negative pressure airbag is pressed. At this time, the air pressure in the water injection port is reduced. Under the action of the external atmospheric pressure, the muddy water is transported from the water injection port and the water pipe to the filter box.

The sludge filtering negative pressure sedimentation box drives the sludge sweeping plate 10 to slide along the inclined bottom surface of the filter box 7 toward the sludge storage tank 9. The sludge sweeping plate 10 can fit the bottom surface of the filter box 7 and sweep all the precipitated sludge into the sludge storage tank 9, so that the overall filtering effect is better. Therefore, it is only necessary to operate the sludge sweeping plate 10 each time to complete the cleaning. Compared with the traditional method of taking out the filter box 7 to clean the sludge, its operation is simpler.

[0040] like Figure 8 As shown, vertically arranged sleeves 12 are fixed to the tops of both ends of the slag sweeping plate 10, and a movable sliding handle 13 is slidably installed in the sleeve 12; the movable sliding handle 13 is an L-shaped handle, and the movable sliding handle 13 extends all the way to the outside of the sedimentation box 3. In order to facilitate the sliding of the slag sweeping plate 10, the movable sliding handle 13 is operated to guide the slag sweeping plate 10 to slide, and the slag sweeping plate 10 is driven to slide along the inclined bottom surface of the filter box 7 to the location of the slag storage tank 9. The slag sweeping plate 10 can fit the bottom surface of the filter box 7 and sweep all the precipitated mud into the slag storage tank 9, and the slag storage tank 9 can be cleaned when it is full.

[0041] like Figure 8 As shown, a gate 14 is also installed at the slag storage tank 9, and both sides of the gate 14 are slidably installed in the slide grooves 15 fixed on the filter box 7.
