Description

Technical Field

[0001] This utility model belongs to the field of textile wastewater treatment technology, and in particular relates to a resource-based treatment device for high-acid and high-salt wastewater from viscose fiber. Background Technology

[0002] In the continuous spinning process of viscose fiber, a large amount of desalinated water is required to wash the filaments to remove the components of the spinning bath (a mixed solution of sodium sulfate, zinc sulfate, and sulfuric acid) adhering to them. Currently, the continuous spinning production process generally consists of four washing stages: the first, second, third, and fourth washing stages. The wastewater discharged from these stages contains a certain degree of acidity and salt. Direct discharge would result in resource waste, necessitating purification, recycling, and reuse to increase resource utilization. During recycling, the wastewater needs to be filtered before it can be reused. However, the resource utilization equipment for high-acid and high-salt wastewater from viscose fiber production still has the following drawbacks in practical use:

[0003] 1. In the process of wastewater treatment, traditional filter cartridges are directly used for filtration. During the filtration process, the surface of the filter cartridge is cylindrical. As filtration proceeds, the filtration efficiency drops rapidly due to the limited filtration area, thus affecting the filtration efficiency.

[0004] 2. As filtration proceeds, backwashing is required to clean the impurities attached to the filter structure. However, during the backwashing process, the filter structure is subjected to the pressure of the backwash, which can easily cause deformation of the filter structure and affect subsequent filtration. Utility Model Content

[0005] The purpose of this utility model is to provide a resource-based treatment device for high-acid and high-salt wastewater from viscose fibers. By setting up a containment chamber, a filter assembly, and a top cover, it solves the problems in the filtration process of high-acid and high-salt wastewater from viscose fibers, such as the limited filtration area of ​​the filter equipment affecting filtration efficiency, and the easy deformation of the filter structure during backwashing, which affects subsequent filtration.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a resource-based treatment device for high-acid and high-salt wastewater from viscose fiber, comprising a receiving chamber, a filter assembly, and a top cover. The filter assembly is fixed to the bottom of the receiving chamber. The filter assembly includes a fixed rod, connecting rods, support rings, and annular filter cloth. The bottom end of the fixed rod is fixed to the bottom of the receiving chamber. Several parallel support rings are arranged around the fixed rod. Connecting rods are fixed in a circular array on the inner ring of each support ring. All connecting rods are fixed to the periphery of the fixed rod. Annular filter cloths are symmetrically fixed around the periphery of each support ring. The top cover is fixed to the top of the receiving chamber. During operation, the receiving chamber contains the wastewater to be filtered. The filter assembly filters the wastewater entering the receiving chamber. During wastewater filtration, the support rings provide support for the annular filter cloth, and the annular filter cloth forms a pleated structure, increasing the filtration area and filtration efficiency. Simultaneously, the top cover seals the top of the receiving chamber.

[0008] Furthermore, a support is fixed to the lower part of the periphery of the receiving chamber, and a drain pipe is fixedly connected to the upper part of the periphery of the receiving chamber. An electric control valve three is fixed to the periphery of the drain pipe. The support on the periphery of the receiving chamber supports the receiving chamber on the working plane. The drain pipe discharges the water after cleaning in the receiving chamber. The electric control valve three controls the flow of the drain pipe.

[0009] Furthermore, a discharge pipe is fixedly connected to one side of the fixing rod at the bottom of the receiving chamber, and an electrically controlled valve is fixed to the periphery of the discharge pipe. The wastewater in the receiving chamber that has been filtered by the filter assembly is discharged into the next treatment process through the discharge pipe.

[0010] Furthermore, a flushing pipe is fixedly connected to the bottom of the receiving chamber at a position symmetrical to the center of the discharge pipe. An electric control valve is fixed to the periphery of the flushing pipe. The flushing pipe on the receiving chamber delivers flushing water into the receiving chamber, and the electric control valve controls the on / off of the flushing pipe.

[0011] Furthermore, the two annular filter cloths between adjacent support rings are fixed to each other, and the bottom end of the annular filter cloth located at the lower part of the periphery of the lowest support ring is fixed to the inner bottom of the receiving chamber. The top ends of the discharge pipe and the flushing pipe are both set on the inner ring of the lowest annular filter cloth, so that filtering folds are formed between the annular filter cloths.

[0012] Furthermore, an input pipe is fixedly connected to the center of the top of the top cover, the filter assembly also includes a sealing cover, the top of the connecting rod is fixed with a sealing cover, the bottom of the sealing cover is fixed to the top of the annular filter cloth located on the upper side of the uppermost support ring, the top cover closes the top of the receiving chamber, and the sealing cover at the top of the connecting rod closes the top of the annular filter cloth located on the uppermost side.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model solves the problem of limited filtration area and reduced filtration efficiency in the filtration process of high-acid and high-salt wastewater resource treatment of viscose fiber by setting up a receiving chamber and a filter assembly. Wastewater is transported to the receiving chamber through the input pipe on the top cover. Under the action of wastewater pressure, it is transported to the annular filter cloth included in the filter assembly. After being filtered by the annular filter cloth, it is transported to the cavity inside the filter assembly. The two annular filter cloths between two adjacent support rings are fixed to each other to form a pleated structure for filtration, which increases the filtration area and makes the filtration efficiency of wastewater higher.

[0015] 2. This utility model solves the problem that the filter structure is prone to deformation during backwashing in the filtration process of viscose fiber high acid and high salt wastewater resource treatment by setting up a receiving chamber, filter components and a top cover, which affects subsequent filtration. When the wastewater is transported into the receiving chamber, it is filtered by the filter components in the receiving chamber and then transported to the discharge pipe for discharge. After filtration for a period of time, the first solenoid valve is closed and the second and third solenoid valves are opened. At this time, the rinsing water is transported to the filter components in the rinsing pipe and backwashes the filter components before being transported to the drain pipe and discharged to the equipment for discharging cleaning water through the drain pipe, thus completing the rinsing. During the rinsing process, the support rings provide support for the annular filter cloth, and during rinsing, the annular filter cloth between two adjacent support rings is turned up, and the impurities filtered between the folds of the annular filter cloth are discharged. By using flexible annular filter cloth for filtration, it is not easily damaged during backwashing. Attached Figure Description
