Description
Technical Field
The utility model relates to a crystalline silicon production facility field, in particular to crystalline silicon machining equipment sewage cycle processing system.
Background
In the solar photovoltaic industry, equipment used for crystalline silicon machining, such as a flour mill, a slicing machine or a cutting machine, needs a large amount of circulating water for cooling, and silicon slag, silicon chips and silicon fragments falling in the machining process are mixed in the circulating water, so that the slag content in the circulating water is gradually increased in the machining process, the smoothness of a circulating pipeline is affected, and finally, sewage for forming a silicon-water mixture needs to be discharged for supplying clean water. In the prior art, one method for discharging the circulating sewage is to directly discharge the sewage after simple filtration, and the other method is to intensively process and treat the sewage (containing other chemical component water) discharged by other equipment in a production field. The former has the disadvantages of large waste water discharge pollution and water resource waste; the latter can intensively treat the wastewater with different pollution components, which can increase the difficulty of wastewater treatment and increase the treatment cost.
SUMMERY OF THE UTILITY MODEL
The utility model discloses not enough to crystalline silicon machining equipment's circulation sewage treatment discharge mode among the prior art, provide a crystalline silicon machining equipment sewage circulation processing system, aim at concentrating the circulation sewage of each machining equipment of crystalline silicon and carry out the filtering separation processing, realize the circulation of sewage and recycle, reduce and discharge the pollution.
The utility model aims at realizing like this, a sewage cycle processing system of crystalline silicon machining equipment, including the effluent water sump that is used for collecting each machining equipment circulation discharge water, the play liquid end of effluent water sump has connected gradually diaphragm pump, plate frame filter pressing device's play liquid end is connected with the clean water basin, the play liquid end in clean water basin is connected with out the liquid pipeline, it is connected with the circulation water supply end of each machining equipment respectively through the feed pump to go out the liquid pipeline, it has the moisturizing pipeline to go back branch connection on the liquid pipeline, the moisturizing pipeline is connected with the moisturizing groove.
The utility model discloses a crystalline silicon machining equipment sewage cycle processing system, concentrate the preliminary treatment with the circulation sewage of each machining equipment, with big silicon chip in the separation sewage, thereby realize preliminary solid-liquid separation, still contain the little solid particle of silicon chip class in the sewage after the separation, further filter-pressing separation is carried out through sheet frame filter-pressing device, with the tiny solid particle and the separation of water of silicon chip class, water after the filter-pressing can directly be mended the inlet channel of recirculated cooling water or get into the inlet channel of recirculated cooling water after mixing with the moisturizing pipeline. Therefore, the sewage circulating treatment system of the crystalline silicon machining equipment can intensively filter the discharged sewage for cooling each machining equipment, recycle the sewage after solid-liquid separation treatment and reduce the sewage discharge; and the treatment system of the utility model only carries out separation treatment to the sewage mixed by single silicon water, has simple treatment process and saves treatment cost.
For the big silicon piece in the convenient preliminary separation dirt, the effluent water sump passes through the filter of vertical direction and separates for feed liquor groove and play liquid groove, the bottom in feed liquor groove is equipped with the drain, the drain is connected with album cinder notch, the middle part of going out liquid groove direction of height is equipped with the liquid outlet, the liquid outlet pass through the liquid pipeline with the diaphragm pump is connected. Through setting up the filter in the effluent water sump, keep apart the silicon piece in the feed liquor inslot to regularly arrange the silicon piece into in the album sediment groove, be convenient for receive the silicon crushed aggregates and carry out concentrated recovery processing, reduce and discharge the pollution.
In order to facilitate the recovery of silicon scraps, the plate frame filter pressing device is provided with a slag discharge port, and the slag discharge port is connected with a slag collecting groove.
