[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached Figures 1-3 in the embodiments of the present utility model.

[0024] Please refer to Figures 1-3 , in the embodiments of the present utility model: An industrial wastewater recycling device includes: a water storage tank 1. A first water inlet 2 is provided on one side wall of the water storage tank 1, and an external water source is connected to the first water inlet 2. When in use, the external water source can be connected. A first water outlet 3 is provided at the upper part of the opposite side wall. When the material to be cleaned only needs to be cleaned once, clean water is introduced into the water storage tank 1. A water pump 9 and a filter 6 are provided at the top of the water storage tank 1. A grille plate 4 and a partition board 5 are vertically arranged inside the water storage tank 1, and the grille plate 4 and the partition board 5 are arranged alternately. The water in the water storage tank 1 is pumped out by the water pump 9 to clean the material. A plurality of funnel-shaped sedimentation parts are provided at the bottom of the water storage tank 1, and a sewage outlet is provided at the lowest position of the bottom of the sedimentation part.

[0025] Further, multiple sets of grille plates 4 and partition plates 5 are provided. The grille plates 4, partition plates 5, and the inner wall of the water storage tank 1 form multiple compartments. The height of the grille plates 4 is the same as the internal height of the water storage tank 1. The grille plates 4 preliminarily filter larger particulate impurities in the washed sewage. The height of the partition plates 5 decreases successively along the water flow direction, and the position of the first water outlet 3 is lower than the last partition plate 5.

[0026] When the materials to be cleaned need to be cleaned multiple times, the water flow direction of the recycling device can be set in the opposite direction to the direction of the pipeline cleaning steps, making it more convenient to collect the washed water into the water storage tank 1. During use, the grille plates 4 and partition plates 5 can be set according to the actual cleaning steps. If necessary, multiple water storage tanks 1 can be set to adapt to the actual use environment.

[0027] When the materials need to be cleaned multiple times, starting from the first cleaning step, the requirements for the cleanliness of the cleaning water increase successively. Therefore, this industrial wastewater recycling device collects the water from the next cleaning step, simply filters and cleans it, and then uses it for the previous cleaning step. Each previous cleaning step has relatively low requirements for the cleanliness of the water from the adjacent next cleaning step, ultimately achieving the maximum utilization of the cleaning water.

[0028] Further, the water inlet end of the water pump 9 communicates with the inside of the water storage tank 1 and is located between the grille plate 4 and the partition plate 5. The water pump 9 is provided after each grille plate 4, enabling it to pump the water filtered from the large particulate impurities in the water collected after the next cleaning step into the filter 6. The water outlet end of the water pump 9 is connected to the water inlet end of the filter 6, and the water from the next cleaning step collected is filtered by the filter 6 and then used for the previous cleaning step.

[0029] Further, in order to more intuitively observe the water volume in the water storage tank 1, an observation window 10 is provided on the side wall of the water storage tank 1. The observation window 10 is made of a transparent material, and a scale 11 is provided on one side of the observation window 10. The bottom end of the scale 11 is flush with the bottom end of the water storage tank 1.

[0030] During use, the water level in each space inside the water storage tank 1 can be observed in real time through the observation window 10 to avoid cross - contamination of the water in each compartment of the water storage tank 1 due to blockage of the subsequent drainage structure.

[0031] Further, in order to timely clean the impurities on the grille plate 4 and prevent excessive impurities from blocking the grille plate 4, the connection between the upper end and the bottom of the side wall of the water storage tank 1 is a slope, and a dirt cleaning port 12 is provided on the slope. A cover 13 is correspondingly provided on the dirt cleaning port 12. When there are too many impurities on the grille, the cover 13 is opened to clean the grille to avoid cross - contamination of the water in the water storage tank 1 caused by its blockage. The water inlet and outlet can also be cleaned through the dirt cleaning port 12.

[0032] Further, a sewage pipe 14 is connected to the outside of the sewage outlet, and a check valve is provided between the sewage outlet and the sewage pipe 14. After the impurities in the precipitation part have precipitated for a certain period of time, the check valve 17 is opened to discharge the precipitated impurities and dirt into the sewage pipe 14, preventing excessive accumulation of dirt from causing repeated pollution of the water source.

[0033] Further, one end of the sewage pipe 14 is connected to a wastewater treatment tank 15. In the wastewater treatment tank 15, according to the nature of the cleaning materials and treatment requirements, screen filtration, sedimentation, clarification, etc. can be set up to remove most of the suspended solids and waste, or chemical agents can be used to remove organic matter, heavy metal ions and other pollutants in the sewage. After the wastewater treatment, a drain pipe 8 is connected between the first water outlet 3 and the wastewater treatment tank 15, and a check valve 17 is provided on the drain pipe 8. A second water outlet 16 is opened on the side wall of the wastewater treatment tank 15.

[0034] To avoid overflow caused by blockage in the water storage tank 1 and the water outlet pipeline, emergency drain openings are provided at the bottom of each space at the bottom of the water storage tank 1. An emergency drain pipe 8 is connected to the bottom of the emergency drain opening, and a valve is provided on the emergency drain pipe 8. When a blockage occurs and the water level is uncontrollable, the valve can be opened to discharge the water into the sewage tank in time.

[0035] Working principle: During use, clean water is introduced into the water storage tank 1 through the first water inlet 2 to perform a complete process of cleaning on the materials to be cleaned. The water after the first cleaning is directly introduced into the wastewater treatment tank 15. Then, the water from the last cleaning is introduced into the first compartment of the water storage tank 1 through the second water inlet 7. Then, the collected water is pumped out by the water pump 9 and used for the previous cleaning step. By setting the grid plate 4, large-particle impurities are preliminarily filtered; by setting the water pump 9, the preliminarily filtered water is pumped into the filter 6 for secondary filtration; by setting the partition plate 5, the interior of the water storage tank 1 is divided into multiple spaces; and by successively reducing the height of the partition plate 5, the water in the subsequent compartments can be prevented from polluting the water in the previous compartment; by setting and successively reducing the height of the partition plate 5, the water in the subsequent compartments can be prevented from polluting the water in the previous compartment. By setting the first water outlet 3, the height of the water in the last compartment inside the water storage tank 1 is always lower than the height of the last partition plate 5, which can not only prevent the pollution of the water in the previous compartment but also avoid leakage caused by excessive water volume in the water storage tank 1; finally, through the sewage outlet, the dirt deposited at the bottom of each compartment flows into the wastewater treatment tank 15 through the sewage pipe 14 for treatment, avoiding environmental pollution caused by random sewage discharge.
