The technical scheme of the utility model specifically does:

the utility model provides a coal water sedimentation tank, which comprises a water tank, the pond divide into sedimentation tank and filtering ponds, the sedimentation tank is located the pond right side, the filtering ponds is located the pond left side, the fixed filtration equipment in the filtering ponds, the bottom surface in sedimentation tank right side district is equipped with desilting operation passageway, desilting operation passageway is less than the sedimentation tank bottom surface, the upper portion UNICOM upper reaches water pipe in sedimentation tank right side district, the leftmost side in pond is the clean water district, filtration equipment's entry UNICOM sedimentation tank, its export UNICOM's clean water district, the top in sedimentation tank left side district is equipped with the overflow wall, the region between overflow wall and the filtering equipment top is overflow passageway, the fixed wall that splits in the sedimentation tank, it extends to the sedimentation tank bottom to split the wall, the upper portion that splits the wall is equipped with a plurality of limbers, limbers UNICOM filtering ponds.

The bottom of the sedimentation tank is an inclined plane, one side of the inclined plane, which is close to the splitting wall, is a high side, and one side of the inclined plane, which is close to the dredging operation channel, is a low side.

The split wall is a concrete wall.

The filtering equipment is a microporous ceramic filtering wall.

Compared with the prior art, the technical effect of the utility model is that, the utility model discloses be equipped with and cut the wall that splits, stay more impurity in the sedimentation tank, reduced filtration equipment's pressure, improved life.

Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are clearly and completely described with reference to the drawings in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In the present invention, it is noted that relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.

When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Furthermore, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like are used herein to indicate orientations or positional relationships based on the drawings, and are used for convenience in describing the present invention, but do not indicate or imply that the device or element so referred to must have this particular orientation, be operated in a particular orientation configuration, and not be construed as limiting the present invention.

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments thereof.

As shown in fig. 2, a coal water sedimentation tank, including the pond, the pond divide into sedimentation tank 10 and filtering ponds, sedimentation tank 10 is located the pond right side, the filtering ponds are located the pond left side, fixed filtration equipment 20 (specifically microporous ceramic filter wall) in the filtering ponds, the bottom surface in sedimentation tank 10 right side district is equipped with desilting operation passageway 12, desilting operation passageway 12 is less than sedimentation tank 10 bottom surface, the upper portion UNICOM upstream water pipe 11 in sedimentation tank 10 right side district, the leftmost side in pond is clear water district 21, filtration equipment 20's entry UNICOM sedimentation tank 10, its export UNICOM clear water district 21, the top in sedimentation tank 10 left side district is equipped with overflow wall 30, the region between overflow wall 30 and the filtration equipment 20 top is overflow channel 31.

A cracking wall 40 is fixed in the sedimentation tank 10, the cracking wall 40 extends to the bottom of the sedimentation tank 10, a plurality of water through holes 41 are formed in the upper portion of the cracking wall 40, and the water through holes 41 are communicated with the filtering tank.

After long-time use, the bottom of the sedimentation tank 10 has more sediments, and the sediments need to be cleaned. The bottom of the sedimentation tank 10 is an inclined plane 13, the side of the inclined plane 13 close to the fracture wall 40 is a high side, and the side of the inclined plane 13 close to the dredging operation channel 12 is a low side.

The split wall 40 is a concrete wall for strength.

The working principle is as follows:

during the use, the upstream comes water to get into sedimentation tank 10 from upstream water pipe 11 in, and comparatively muddy water is located the lower floor, and comparatively clear water is located the upper strata, and when water was more, clear water got into the filtering ponds from limbers 41, got into clear water district 21 for use in the filtration equipment 20 again, accomplished the sediment filtration operation.

Through optimizing the transformation to the sedimentation tank, effectively separate coal water sedimentation district and filtering area, the outstanding sedimentation function of sedimentation tank guarantees the filtration efficiency of filtering area, reduces filtering area desilting and filter rod clearance change cycle, reduces the sedimentation tank desilting degree of difficulty. Meanwhile, the replacement cost of the filtering equipment is saved, and the labor intensity of dredging of the sedimentation tank is reduced.

See the prior art for additional details.

While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
