Description

Technical Field

[0001] The utility model belongs to the technical field of artificial crystal production and processing, and particularly relates to a crystal wastewater crystal impurity filtering device. Background Art

[0002] The production process of artificial crystals uses seed crystal racks, crystal reactors, grinding and polishing devices, and wastewater treatment devices. The wastewater treatment device is used in the last link of artificial crystal production and processing. This link often uses tank devices such as reaction tanks and separation tanks. Its purpose is to uniformly treat the water used in crystal production and discharge it after the treatment meets the standards.

[0003] In the prior art, the treatment of crystal wastewater can refer to the patent with publication number CN109650578A, which discloses a crystal wastewater treatment process, including the following steps: step 1, filtering out large particle impurities in the wastewater through a grid; step 2, sending the wastewater into a reaction tank, adding 200g-250g of a reagent to 1000ml-1200ml of the wastewater; step 3, turning on the mixer, ensuring that the stirring time is not less than 50min-70min, and ensuring that the wastewater and the reagent are fully mixed; step 4, pouring the wastewater into a separation tank, naturally settling for 10min-15min, and removing surface floating objects; step 5, turning on the separation system for separation; step 6, pouring the wastewater into a secondary separation tank, and separating after natural sedimentation for 15min-20min; step 7, filtering the separated water through activated carbon and discharging it.

[0004] The above-mentioned patents can solve the technical problems of easy agglomeration of crystal powder in crystal wastewater and low treatment efficiency. However, the treatment tank devices such as reaction tanks and separation tanks used for treating crystal wastewater adopted by this type of technology will have impurities mainly containing silicon crystals attached to their interior after a period of use. Therefore, it is necessary to conduct a comprehensive cleaning of the interior of the tank device every once in a while, otherwise the treatment effect and efficiency of the crystal wastewater will be reduced. Since the impurities mainly containing silicon crystals are hard in texture and are extremely difficult to clean after being attached to various parts inside the tank device, this not only increases the difficulty and time of manual cleaning, but also affects the efficiency of crystal production from the factory's perspective.

[0005] Therefore, the applicant proposed a front-end preliminary filtering device for crystal wastewater treatment tank devices such as reaction tanks and separation tanks to partially clean up silicon crystal impurities from the input end of the tank, reduce the concentration of silicon crystal impurities and other impurities entering the tank, and reduce the difficulty and cleaning time of subsequent manual cleaning inside the tank.

[0031] An impurity trough 12 is provided in the primary filter water tank 1 and near the water outlet. The bottom of the impurity trough 12 is a filtering surface with a plurality of meshes. The upper opening of the impurity trough 12 is located below the end of the grid conveyor belt 4 close to the water outlet of the primary filter water tank 1.

[0032] The water inlet of the primary filter water tank 1 is used to connect with the water outlet end of the water inlet pipe 6;

[0033] The grid conveyor belt 4 is used to lift the crystal wastewater entering from the water inlet pipe 6, so that the crystal wastewater is lifted from the water inlet end of the primary filter water tank 1 to the water outlet end, and falls into the impurity tank 12 from the water outlet end of the primary filter water tank 1; then the impurity tank 12 is used to filter the crystal wastewater, and silicon crystal impurities larger than the mesh aperture at the bottom of the impurity tank 12 remain on the mesh; the water after preliminary filtration flows into the middle and lower part of the primary filter water tank 1;

[0034] A driving shaft of an external motor is provided on the grid conveyor belt 4, and the grid conveyor belt 4 is driven by the external motor to perform a lifting action.

[0035] like Figure 2 As shown, a hanging block 13 is fixedly provided on the impurity tank 12, and the impurity tank 12 is hung on the frame 11 on the water outlet side of the primary filter water tank 1 through the hanging block 13. With this structure, it is convenient to take out, clean, and replay the impurity tank 12 after cleaning.

[0036] The end of the impurity tank 12 close to the water outlet of the primary filter water tank 1 is welded with two symmetrically arranged ears 14, and the ears 14 are connected to the frame 11 through bolt rods 15. This can enhance the tightness of the connection between the impurity tank 12 and the primary filter water tank 1 and the overall strength.

[0037] The water outlet end of the primary filter water tank 1 is provided with a water outlet, which is used to connect with the water inlet of the secondary filter mechanism;

[0038] like Figure 3 As shown, the secondary filtering mechanism includes a three-way pipe 7, a first interface of the three-way pipe 7 is connected to the water outlet of the primary filtering water tank 1, a second interface of the three-way pipe 7 is connected to the impurity box 10, an outer thread joint 8 is provided at the interface of the second interface of the three-way pipe 7, and an inner thread joint 9 is provided at the interface of the impurity box 10, the outer thread joint 8 cooperates with the inner thread joint 9 to realize the connection between the second interface of the three-way pipe 7 and the impurity box 10; at the same time, it is convenient to take out the impurity box 10 to clean its interior.

During this process, the grid conveyor belt 4 is turned on, so that the grid conveyor belt 4 drives the baffle 5 to convey the wastewater containing silicon crystal impurities passed into the primary filter water tank 1 to the impurity tank 12. The impurity tank 12 filters the crystal wastewater, and the silicon crystal impurities larger than the mesh aperture at the bottom of the impurity tank 12 remain on the mesh; the water after preliminary filtration flows into the middle and lower part of the primary filter water tank 1;
