Description

Technical Field

[0001] This utility model relates to the field of hazardous waste treatment technology, specifically to a wastewater treatment device for hazardous waste treatment. Background Technology

[0002] Wastewater refers to water that has lost its use value or has been polluted during production, daily life and other activities.

[0003] The wastewater generated during hazardous waste treatment is complex in composition and contains a large number of harmful substances. If it is discharged directly without effective treatment, it will cause serious environmental pollution. Therefore, wastewater treatment equipment is often used. Although existing wastewater treatment equipment can treat wastewater in actual use, it generally does not have the function of automatically cleaning the filter screen. Because the filter screen will accumulate a lot of impurities on its surface and inside after working for a long time, failure to clean it in time will affect the wastewater treatment efficiency. The existing cleaning methods mostly rely on manual cleaning with tools. This cleaning method not only increases the workload of operators, but also has low cleaning efficiency. Therefore, it needs to be improved. Utility Model Content

[0031] like Figures 1-5As shown, a wastewater treatment device for hazardous waste treatment according to an embodiment of the present disclosure is illustrated, including a wastewater treatment tank 1. A filter screen plate 2 is fixedly installed inside the wastewater treatment tank 1. A lifting motor 3 is fixedly connected to the top of the wastewater treatment tank 1. A rotating shaft 4 is fixedly sleeved at the other end of the output shaft of the lifting motor 3. A rotating rod 5 is fixedly sleeved on the outer surface of the rotating shaft 4. A round shaft 6 is fixedly sleeved inside the other end of the rotating rod 5. A T-shaped block 7 is movably connected to the outer surface of the round shaft 6. The bottom of the T-shaped block 7 penetrates through the wastewater treatment tank 1 and extends into the interior of the wastewater treatment tank 1 and is fixedly connected to a brush plate 8. The outer surface of the brush plate 8 is movably connected to the inner surface of the wastewater treatment tank 1, and the right side of the brush plate 8 is movably connected to the left side of the filter screen plate 2.

[0032] When the lifting motor 3 is running, the rotating shaft 4 will drive the rotating rod 5 to rotate, which in turn will cause the round shaft 6 to rotate and drive the T-shaped block 7 to move downward, thereby causing the brush plate 8 to move downward to clean the surface of the filter screen plate 2, thus achieving the purpose of automatically cleaning the filter screen plate 2 and improving the filtration effect of the filter screen plate 2.

[0033] In some examples, the top of the wastewater treatment tank 1 is fixedly connected with two limit rods 9, and the outer surfaces of the two limit rods 9 are movably sleeved with the inner surface of the T-block 7.

[0034] The design of the two limit rods 9 serves to limit the movement of the T-block 7, ensuring the stability of the T-block 7 during lifting and lowering.

[0035] In some examples, a side cavity 10 is provided inside the bottom of the wastewater treatment tank 1. A baffle 11 is movably connected to the inner surface of the side cavity 10. A sealing plate 12 is fixedly connected to the top of the baffle 11. The outer surface of the sealing plate 12 is movably connected to the inner surface of the side cavity 10.

[0036] The design of the sealing plate 12 serves to ensure the overall sealing of the wastewater treatment tank 1.

[0037] In some examples, the wastewater treatment tank 1 has an internal threaded connection to a threaded rod 13 on the front side, with the other end of the threaded rod 13 passing through the baffle 11 and extending into the interior of the baffle 11.

[0038] Rotating the threaded rod 13 outward releases the fixing effect on the baffle 11. Then, pulling the baffle 11 to the right releases the sealing effect on the bottom of the wastewater treatment tank 1, allowing the brush plate 8 to discharge the cleaned debris to the outside of the wastewater treatment tank 1.

[0039] In some examples, an inlet 14 is fixedly connected to the left side of the wastewater treatment tank 1, a valve 15 is fixedly installed at the bottom right side of the wastewater treatment tank 1, and a drain outlet 16 is fixedly connected to the right side of the valve 15.

[0040] This design allows wastewater to be introduced into the wastewater treatment tank 1 through the inlet 14. After treatment, the wastewater can be discharged to the outside through the outlet 16 by opening the valve 15.

[0041] In some examples, the top of the wastewater treatment tank 1 is fixedly connected to a dosing port 17 located to the right of the lifting motor 3, and the top of the dosing port 17 is hinged to a cover plate 18, and the top of the cover plate 18 is fixedly connected to a handle 19.

[0042] Pulling the handle 19 will rotate the cover 18 and release the seal on the top of the dosing port 17, allowing chemicals to be added into the wastewater treatment tank 1 through the dosing port 17 to treat the wastewater.

[0043] In some examples, the top of the wastewater treatment tank 1 is movably connected to a stirring motor 20 located behind the dosing port 17. The other end of the output shaft of the stirring motor 20 is fixedly sleeved with a stirring shaft 21. The bottom of the stirring shaft 21 penetrates the wastewater treatment tank 1 and extends into the interior of the wastewater treatment tank 1, and is fixedly sleeved with stirring blades 22.

[0044] When the stirring motor 20 is running, the stirring shaft 21 will drive the stirring blades 22 to rotate, so that the agent can be mixed evenly with the wastewater.

[0045] In some examples, a drive motor 23 located to the right of the stirring motor 20 is fixedly connected to the top of the wastewater treatment tank 1. A lead screw 24 is fixedly sleeved at the other end of the output shaft of the drive motor 23. A fixed plate 25 is movably sleeved at the other end of the lead screw 24. The bottom of the fixed plate 25 is fixedly connected to the top of the wastewater treatment tank 1. A movable plate 26 is threaded onto the outer surface of the lead screw 24. A rotating rod 27 is hinged to the top of the movable plate 26. An L-shaped plate 28 is hinged to the other end of the rotating rod 27. The bottom of the L-shaped plate 28 is fixedly connected to the top of the stirring motor 20.

[0046] When the drive motor 23 is running, the lead screw 24 will rotate, causing the movable plate 26 to move backward, which in turn causes the rotating rod 27 to rotate, causing the L-shaped plate 28 to move upward, thereby causing the stirring motor 20 to move upward as a whole, thus achieving the purpose of accelerating the mixing efficiency of the reagent and wastewater.

[0047] In some examples, the top of the wastewater treatment tank 1 is provided with a chute 29 located directly below the lead screw 24, and the inner surface of the chute 29 is movably connected to the outer surface of the movable plate 26.

[0048] The design of the slide 29 serves to limit the movement of the movable plate 26, ensuring the stability of the horizontal movement of the movable plate 26.

[0049] In some examples, four support legs 30 are fixedly connected to the bottom of the wastewater treatment tank 1, and the four support legs 30 are symmetrical about the center of the wastewater treatment tank 1.

[0050] The design of the four wastewater treatment tanks 1 serves to provide overall support for the wastewater treatment tanks 1.

[0051] Working principle and usage process of this utility model:

[0052] When treating wastewater, the wastewater is first introduced into the wastewater treatment tank 1 through the inlet 14. After being filtered by the filter screen 2, the wastewater flows to the other side of the filter screen 2. Then, pulling the handle 19 and rotating the cover 18 will release the sealing effect on the top of the dosing port 17. Subsequently, chemicals are added into the wastewater treatment tank 1 through the dosing port 17 to treat the wastewater. At this time, the stirring motor 20 is started, which will cause the stirring shaft 21 to drive the stirring blade 22 to rotate. At the same time, the drive motor 23 is started, which will cause the lead screw 24 to rotate and drive the movable plate 26 to move backward. This will cause the rotating rod 27 to rotate and drive the L-shaped plate 28 to move upward, thereby causing the stirring motor 20 to move upward as a whole. Under the action of the up-and-down movement and rotation of the stirring blade 22, the mixing efficiency of the chemicals and wastewater is accelerated, thereby improving the wastewater treatment efficiency. After the wastewater treatment is completed, the valve 15 is opened and the treated wastewater can be discharged through the drain port 16.

[0053] Because the filter screen 2 will accumulate a large amount of impurities on its surface and inside after working for a long time, failure to clean it will affect the wastewater filtration efficiency. First, rotate the threaded rod 13 outward to release the fixing effect on the baffle 11. Then, pull the baffle 11 to the right to release the sealing effect on the bottom of the wastewater treatment tank 1. Then, start the lifting motor 3, which will cause the rotating shaft 4 to drive the rotating rod 5 to rotate, which in turn causes the round shaft 6 to rotate and drive the T-block 7 to move downward. This causes the brush plate 8 to move downward to clean the surface of the filter screen 2. The cleaned debris can be discharged to the outside of the wastewater treatment tank 1, improving the filtration effect of the filter screen 2.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
