Technical Field

[0001] The utility model belongs to the technical field of chemical wastewater purification, and particularly relates to a micro-silicon particle wastewater recycling device. Background Art

[0002] Existing semiconductor material and component packaging companies and chemical synthesis companies, during the production process, some semi-finished products will reduce the purity of the finished products due to crystallization and some impurities, and it is necessary to remove impurities and micro-particle crystals in the semi-finished products; electroplating production lines and semiconductor packaging lines will generate a large amount of cleaning wastewater for cleaning workpieces, and the water mostly contains pollutants such as high suspended solids, micro-particles, and colloids. The traditional filtration process is long and the filtration accuracy is poor, resulting in a decrease in the yield of workpieces after being reused in the production line. The use of organic materials for membrane filtration has problems such as easy fouling and difficult recovery, and may even directly lead to membrane damage and system scrapping.

[0003] Therefore, in order to remove pollutants such as highly suspended solids, microparticles, and colloids from cleaning wastewater and solve the above problems, a microsilicon particle wastewater reuse device is proposed. Summary of the Invention

[0004] In order to solve the problems raised in the above background technology, the utility model provides a micro-silicon particle wastewater recycling device. The wastewater in the raw water tank is input into the mixing drum through the raw water delivery pump to be mixed and stirred with the input flocculant. The pressure water pump inputs the filter to remove suspended impurities in the water body. After purification, it is transported to the production water tank. The backwash water pump is also used to return the water to the filter for further filtration. The water is adsorbed by the activated carbon filter drum and zeolite filter by the constant pressure external water supply pump and then sent out by the filter pump, completing the impurity removal and filtration treatment in the wastewater and improving the utilization rate of water resources.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a micro-silicon particle wastewater reuse device, comprising a machine base, on which a raw water tank, a mixing drum, and a production water tank are installed. The top of the raw water tank is connected to a water pipe from the production line. The bottom right side of the raw water tank is connected to the top of the mixing drum through a raw water delivery pump via a pipeline. The mixing drum is connected to a filter arranged on the machine base through a pressure water pump via a pipeline. The top of the filter is connected to the top of the production water tank through a second pressure water pump. The bottom left side of the production water tank is connected to the filter through a backwash water pump via a backwash water pipe. The bottom right side of the production water tank is connected to a columnar activated carbon filter cartridge and a zeolite filter through a constant pressure external water supply pump.

[0006] As a preferred solution, the filter adopts an MF backwash filter, the pipeline on the top of the filter is connected to the air compressor air pipe through the backwash air pump, and the bottom of the filter is connected to the backwash drainage pump through the drain pipe.

[0007] As a preferred solution, a sedimentation tank connected to the bottom end of the raw water tank is provided inside the left end of the machine base.

[0008] As a preferred solution, a flocculant cylinder is provided above the mixing and stirring cylinder, and the bottom end of the flocculant cylinder is connected to the top of the mixing and stirring cylinder through a flow input pump; stirring rods are provided inside the raw water tank, mixing and stirring cylinder, flocculant cylinder and produced water tank, and the upper end of the stirring rod extends out to drive and connect a stirring motor, and liquid level observation windows and liquid level meters are respectively provided on the top and front of the raw water tank, mixing and stirring cylinder, flocculant cylinder and produced water tank.

[0009] As a preferred solution, a measuring device is provided on the connecting pipeline between the second pressure water pump and the production water tank, and the measuring device includes a pressure gauge, a flow meter and a thermometer.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The utility model uses a production line water that flows through a production line water pipe into a raw water tank for temporary storage. The wastewater is pumped into a mixing drum by a raw water delivery pump and mixed with flocculant input by a flow input pump. The mixing drum is internally mixed and stirred by a stirring motor to drive a stirring rod, so that the colloid and fine suspended matter therein are coagulated to form a larger colloid feather. The wastewater is then further input into a filter by a pressure water pump. The filter screen is used to directly intercept impurities in the wastewater, remove suspended matter and particulate matter in the water body, reduce turbidity, purify water quality, and reduce the generation of dirt, algae, rust, etc. in the system. The MF backwash filter can also automatically identify the degree of impurity deposition and send a signal to the backwash drainage pump for automatic sewage discharge.

[0012] After being filtered by the MF backwash filter, the second pressure water pump is turned on to transport it to the water production tank. The backwash water pump can also be used to return to the filter inside for filtration again through the backwash water pipe in conjunction with the air compressor air pipe under the operation of the backwash air pump. After repeated filtration, it enters the water production tank and is finally further adsorbed and filtered by the columnar activated carbon filter cartridge and zeolite filter by the constant pressure external water supply pump; then it is pumped out to complete the removal and filtration purification of colloidal corrosion products in industrial wastewater; it can reduce the sewage discharge pressure of end users and improve the utilization rate of water resources.
