Description

Slurry flocculation supply device for mud-water separation

Technical Field

The application relates to the technical field of mud-water separation equipment, in particular to a slurry flocculation supply device for mud-water separation.

Background

The cement is a powdery hydraulic inorganic cementing material, is added with water and stirred to form slurry, can be hardened in air or water, and can firmly bond materials such as sand, stone and the like together. The mortar and concrete supported by cement are firm and durable, and are widely applied to engineering such as civil construction, water conservancy and national defense as important building materials. Waste cement generated in the construction process is generally washed by water to clean the environment or equipment, and muddy water generated by cleaning is diluted cement which is easy to block a pipeline and has certain pollution so as not to be directly discharged into the environment. Therefore, the sludge and water generated by cleaning the waste cement need to be treated to be harmless and then discharged, and the conventional treatment method generally adopts a belt filter pressing method or a centrifuge dewatering method to complete solid-liquid separation, but the method has high operation cost and low separation efficiency.

SUMMERY OF THE UTILITY MODEL

In order to solve prior art and have the problem that waste cement treatment cost is high and efficient, this application provides a thick liquid flocculation feeding mechanism for mud-water separation, can carry out preliminary solid-liquid separation to the mud water that the water content that washes waste cement and produce is very high, shows to carry it to in subsequent further solid-liquid separation equipment again after reducing the water content of mud water to reduce waste cement treatment cost and raise the efficiency.

In order to achieve the purpose, the technical scheme adopted by the application is as follows:

a slurry flocculation supply device for mud-water separation comprises a flocculation container and a primary sedimentation container which are communicated with each other, wherein a stirring device is arranged in the flocculation container, and a sludge pump is arranged at the bottom of the primary sedimentation container; flocculation container bottom and conveyer pipe intercommunication, the conveyer pipe extends along the direction of height at the one end of keeping away from the flocculation container and forms vertical portion, be equipped with respectively with the row mud passageway and the overflow passageway of just settling container bottom and top intercommunication in vertical portion.

In the process of constructing bridges, dams, buildings and the like, a large amount of cement needs to be used, equipment, containers and the like need to be cleaned regularly in a project, for example, the interior of a cement mortar tank truck is washed, the muddy water generated by washing contains a certain amount of cement, and the muddy water cannot be directly discharged into the environment in order to avoid environmental pollution and pipeline blockage, so that solid-liquid separation is needed for harmless treatment. And directly putting the cement with extremely high dilution into a solid-liquid separation device can cause the separation cost to be too high and the separation effect to be poor.

The device that this scheme provided is used for adopting the lower separation method of cost to carry out preliminary concentration to muddy water at muddy water earlier stage, reduces the water content of muddy water to muddy water after the concentration can dewater fast and reach better dehydration effect after getting into solid-liquid separation equipment such as belt filter press in the later stage. When the device is used, the flocculating agent and muddy water are conveyed into the flocculation container, the flocculating agent is quickly and uniformly distributed in the muddy water by using the stirring effect of the stirring device, and flocculation begins to be carried out in the stirring process. After the stirring is uniform, a passage formed by the conveying pipe, the vertical part and the sludge discharge channel is opened, the muddy water enters the primary sedimentation container to be stood and precipitated, and in the flocculation process, originally, dispersed solid substances in the water are coagulated to form sludge clusters with larger weight and diameter, so that the process of solid-liquid separation is accelerated.

Furthermore, the top of the flocculation container is communicated with a medicament input port, and a guide plate which can uniformly disperse the medicament is arranged below the medicament input port in the flocculation container. The setting of guide plate makes a large amount of flocculation medicaments get into the flocculation container through the medicament input port after, falls to the guide plate surface, through the dispersion back of guide plate, falls into the muddy water to the mode of relative even, reduces the required time of flocculating agent homodisperse to the muddy water.

Example 1:

the slurry flocculation supply device for sludge-water separation as shown in figure 1 comprises a flocculation container 1 and a primary sedimentation container 4 which are communicated with each other, wherein a stirring device is arranged in the flocculation container 1, and a sludge pump is arranged at the bottom of the primary sedimentation container 4; flocculation container 1 bottom and conveyer pipe 2 intercommunication, conveyer pipe 2 extends along the direction of height in the one end of keeping away from flocculation container 1 and forms vertical portion, be equipped with in the vertical portion respectively with the row's mud passageway 3 and the overflow path 7 of 4 bottoms and top intercommunications of preliminary sedimentation container.

The working principle is as follows:

as shown in the drawings, in the present embodiment, there are two containers for sludge-water to perform preliminary solid-liquid separation, i.e. a flocculation container 1 and a primary sedimentation container 4, which are communicated with each other through a conveying pipe 2 similar to an L-shape, in cooperation with a sludge discharge passage 3 and an overflow passage 7, it should be noted that, since there are two passages between the flocculation container 1 and the primary sedimentation container 4, i.e. one passage composed of the conveying pipe 2 and the sludge discharge passage 3, and one passage composed of the conveying pipe 2 and the overflow passage 7, according to the prior art known to those skilled in the art, in the case that there are multiple passages between different containers, in order to ensure that the multiple passages can respectively play their roles, a device capable of opening and closing the passages should be disposed in the passages or at the ends of the passages. When the sludge treatment device is used, the muddy water and the flocculating agent are firstly conveyed into the flocculation container 1, the stirring device keeps stirring, so that the flocculating agent is uniformly distributed in the muddy water and is fully contacted with solid substances in the muddy water, then the muddy water is conveyed into the primary sedimentation container 4, the flocculating agent is further flocculated and precipitated in the primary sedimentation container 4, and after the precipitation is finished, the sludge pump pumps the sludge at the bottom of the primary sedimentation container 4 out to subsequent sludge treatment equipment. The overflow channel 7 is used to control the height of the liquid level in the primary sedimentation container 4, and when the liquid level in the primary sedimentation container 4 is higher than the overflow channel 7 and the channel consisting of the delivery pipe 2, the vertical portion and the overflow channel 7 is opened, the muddy water flows back into the flocculation container 1. It should be noted that the sludge pump is an existing device, such as the sludge pump illustrated in fig. 3, the pump body 9 is disposed outside the container, but is communicated with the inside of the container through a pipeline, and meanwhile, the pump body 9 is additionally connected with the output pipeline 6, so as to directionally convey the extracted sludge to other devices or containers. In addition, since the present application belongs to a part of a process for performing a harmless treatment of waste cement, as shown in fig. 2, a return line 5 for communicating the primary sedimentation container 4 with a subsequent treatment facility or container is further provided.

It is worth to be noted that the muddy water in the flocculation container 1 can be uniformly mixed with the flocculating agent, then is conveyed to the primary sedimentation container 4, and is kept stand in the primary sedimentation container 4 to complete the flocculation precipitation process; or the mixture can be uniformly mixed with a flocculating agent in the flocculation container 1, and then conveyed to the primary sedimentation container 4 after primary flocculation sedimentation, and further sedimentated in the primary sedimentation container 4. The difference between the two is that the former easily leaves more solid substances in the flocculation container 1, and the frequency of cleaning the inner wall of the flocculation container 1 needs to be increased, but one flocculation container 1 can be connected with a plurality of primary sedimentation containers 4, so that the treatment efficiency is improved; when the muddy water is conveyed to the primary sedimentation container 4, the muddy water with extremely high solid matter content is firstly output, and then the output muddy water has less and less solid matters and is gradually clear, so that the washing effect on the inner wall of the flocculation container 1 and the stirring device is achieved, and the solid matter residue in the flocculation container 1 is reduced.

this example is further optimized and defined based on example 1.

As shown in fig. 4 and 5, the top of the flocculation container 1 is communicated with a medicament input port 13, and a guide plate 14 for uniformly dispersing the medicament is arranged below the medicament input port 13 in the flocculation container 1. In the actual structural arrangement, as shown in fig. 4, the cross-sectional area of the top of the flocculation container 1 is reduced, the stirring motor 11 in the stirring device is fixed on the top surface, and the medicament inlet 13 is arranged on the side surface. Stirring vane 12 in the agitating unit passes through the connecting rod and is connected with agitator motor 11 and sets up the lower part in flocculation container 1, and this connecting rod and stirring vane 12 synchronous revolution, the cladding has fixed casing outside the connecting rod, the external surface of this casing fixed guide plate 14, and the shape size of guide plate 14 suits with the shape after the flocculation container 1 top shrink. Therefore, the flocculating agent falls into the surface of the guide plate 14 after entering the flocculation container 1 from the medicament input port 13, the surface of the guide plate 14 is inclined, and the flocculating agent slides downwards uniformly along the surface of the guide plate 14.

Example 3:

this example is further optimized and defined based on example 1.

As shown in FIG. 3, the bottom surface of the primary sedimentation container 4 is an inclined surface, and a sludge pump is communicated with the lower part of the primary sedimentation container 4. The design of inclined plane makes solid-state material under the effect of gravity, to lower position motion and deposit and pile up, and corresponding, the pipe connection that connects pump body 9 and primary sedimentation container 4 in the sludge pump is in the low department of primary sedimentation container 4 to improve the discharge efficiency of mud and reduce the moisture content of discharged mud to a certain extent.

In the aspect of controlling the structures of two channels between the flocculation container 1 and the primary sedimentation container 4, butterfly valves are arranged in the sludge discharge channel 3 and the overflow channel 7 and can be controlled manually or automatically.

In addition, other structures of the flocculation container 1 are further limited, and as shown in fig. 2, a plurality of feed inlets 8 are formed at the top of the flocculation container 1. The feed inlet 8 is used for inputing the muddy water, set up a plurality of feed inlets 8 and make flocculation container 1 can connect a plurality of muddy water input pipeline simultaneously, when flocculation container 1 only adds the equipment use of mixing as the medicament, its output is connected a plurality of containers 4 that just sink simultaneously, then the stirring board device in the flocculation container 1 can keep lasting operating condition, muddy water and flocculating agent are carried in continuing to flocculation container 1, directly carry to just sink container 4 after the stirring finishes to this circulation, thereby flocculation container 1 remains the use throughout.
