Abstract
The utility model provides a double-layered concentration tank of a coal preparation plant and belongs to the technical field of the concentration tank of the coal preparation plant. A concentration machine disclosed by the utility model is arranged in a working concentration tank; an outlet of a slime water feeding pipe is communicated with the working concentration tank; the bottom of the working concentration tank is communicated with a lower-layer concentration tank through a pipeline; the bottom of the lower-layer concentration tank is communicated with an inlet of an accident reflowing pump through a pipeline; an outlet of the accident reflowing pump is communicated with the slime water feeding pipe through a pipeline; a clarified water tank of the working concentration tank is communicated with an inlet of a clarified water pump; and an outlet of the clarified water pump is communicated with each water spot pipeline. According to the double-layered concentration tank disclosed by the utility model, the upper layer is the working concentration tank and the concentration machine is mounted; and the lower layer is an accident tank and the concentration machine is not mounted. When the working concentration tank has a fault, upper-layer materials are directly discharged into the lower-layer concentration tank through a bottom flowing opening; and when the fault is removed, the accident reflowing pump is used for pulping slime water back to the upper-layer concentration tank, so as to greatly save the initial investment and operation costs.
Description
Technical field
The utility model relates to the double-deck concentration basin of a kind of coal preparation plant, belongs to coal preparation plant's concentration basin technical field.
Background technology
Coal preparation plant tradition concentration basin is two, and uses, one are standby, normally only work one, when having an accident, it are discharged in another concentration basin, and standby concentration basin becomes the work concentration basin, after the trouble shooting again replacing return.Cause bigger waste like this, need build two big concentration basins, buy two thickeners, and the utilization rate of common standby concentration basin is very low, also uses less than one time in 1 year, thereby ageing equipment is scrapped.Build two concentration basins and caused the waste of civil engineering and equipment investment.
Summary of the invention
The purpose of this utility model is in order to solve the problem that above-mentioned prior art exists, namely to build the waste that two concentration basins have caused civil engineering and equipment investment.And then provide a kind of coal preparation plant double-deck concentration basin.
The purpose of this utility model is achieved through the following technical solutions:
The double-deck concentration basin of a kind of coal preparation plant, comprise: the black water feeding pipe, the work concentration basin, the clarification water pump, lower floor's concentration basin, accident backflow pump and thickener, described thickener is arranged in the work concentration basin, the outlet of black water feeding pipe is connected with the work concentration basin, the bottom of work concentration basin is connected with the lower floor concentration basin by pipeline, the bottom of lower floor's concentration basin is connected by the backflow entrance of pump of pipeline and accident, the accident delivery side of pump that backflows is connected with the black water feeding pipe by pipeline, the clarification water tank of work concentration basin is connected with the entrance of clarification water pump, and the primary water delivery side of pump leads to each and uses the water spot pipeline.
Double-deck concentration basin of the present utility model, upper strata are the work concentration basin, and thickener is installed, and lower floor is an accident pool, and thickener is not installed.During work thickener fault, upper materials directly is discharged into lower floor's accident pool by underflow opening, after the trouble shooting, with the accident pump that backflows black water is returned the upper strata concentration basin again.Initial investment and operation cost have significantly been saved.Facts have proved, utilize the design of double-deck concentration basin up and down, can save construction investment, need not do two big concentration basins again, also saved equipment investment, only need to buy a thickener, namely saved cost of investment; Secondly, convenient management has saved personnel, has avoided unnecessary waste, has saved operation cost, has reached the purpose of energy-saving and emission-reduction.
Description of drawings
Fig. 1 is the double-deck concentration basin structural representation of a kind of coal preparation plant of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail: present embodiment has provided detailed embodiment being to implement under the prerequisite with technical solutions of the utility model, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, the double-deck concentration basin of a kind of coal preparation plant that present embodiment is related, comprise: black water feeding pipe 1, work concentration basin 2, clarification water pump 5, lower floor's concentration basin 7, accident backflow pump 8 and thickener 11, described thickener 11 is arranged in the work concentration basin 2, the outlet of black water feeding pipe 1 is connected with work concentration basin 2, the bottom of work concentration basin 2 is connected with lower floor concentration basin 7 by pipeline, the bottom of lower floor's concentration basin 7 is connected by the backflow entrance of pump 8 of pipeline and accident, the backflow outlet of pump 8 of accident is connected with black water feeding pipe 1 by pipeline, the clarification water tank of work concentration basin 2 is connected with the entrance of clarification water pump 5, and the outlet 10 of clarification water pump 5 is led to each and used the water spot pipeline.
Further, also comprise work underflow pump 3, first valve 4 and second valve 6, described second valve 6 is serially connected on the pipeline between work concentration basin 2 and the lower floor's concentration basin 7, one end of first valve 4 is connected with the pipeline of work concentration basin 2 bottoms, the other end of first valve 4 is connected with the entrance of work underflow pump 3, and filter press is led in the outlet 9 of work underflow pump 3.
The above; it only is the preferable specific embodiment of the utility model; these specific embodiment all are based on the different implementations under the utility model general idea; and protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
