Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a coking wastewater treatment device with multi-stage defluorination function. Background Technology

[0002] Currently, the technologies that can be practically applied to defluoride removal from coking wastewater include adsorption, electrocoagulation, reverse osmosis, ion exchange, chemical precipitation, and coagulation sedimentation. Usually, when treating coking wastewater, it is necessary to combine multiple methods to carry out multi-stage treatment.

[0003] Existing multi-stage treatment equipment typically connects multiple independent defluorination devices with pipelines, which requires a large space. Each device also needs to be cleaned of impurities, requiring manual labor to collect the impurities from multiple devices, which is labor-intensive and time-consuming, affecting processing efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a coking wastewater treatment device with multi-stage defluorination function.

[0005] The technical solution of this utility model is: a coking wastewater treatment device with multi-stage defluorination function, including a bottom chamber, multiple frames that are sequentially nested from top to bottom and slidably sealed in the bottom chamber, and filter screens set at the bottom of each frame. The bottom chamber and the frames are provided with first airbag rods for lifting the frames. A groove and a cleaning plate are provided on the inner wall of one side of the frame. A driving component for driving the cleaning plate to move is provided on the inner wall of the frame. The cleaning plate is slidably sealed to the inner wall of the frame and the inner wall of the groove. A recycling tank that cooperates with the cleaning plate is provided inside the side wall of the other side of the frame.

[0006] Furthermore, the driving component is a spring, the groove is provided with a locking hook that is rotatably connected to the inner wall of the groove by a torsion spring, the cleaning plate is provided with a hook groove for engaging one end of the locking hook, and the upper end of the inner wall of the bottom compartment and the frame is provided with a trigger plate for pressing the other end of the locking hook to disengage one end of the locking hook from the hook groove.

[0007] Explanation: The upward movement of the frame causes the trigger plate to drive the locking hook to disengage from the hook groove, thereby automatically restoring the elastic element and moving the cleaning plate to achieve automatic slag removal.

[0008] Furthermore, the inner wall of the frame is provided with a second airbag rod for driving the cleaning plate to reset, and the air inlet of the second airbag rod is connected to the air outlet of the first airbag rod.

[0009] Explanation: When the frame moves downward, the first airbag rod contracts, causing the second airbag rod to expand and extend, which in turn drives the cleaning plate back to its original position, achieving automatic reset. Furthermore, when the frame moves upward and the first airbag rod extends, the second airbag rod is independently set up with the elastic element, so it will not affect the movement of the elastic element.

[0010] Furthermore, the filter diameter of the plurality of filter screens decreases sequentially from top to bottom.

[0011] Explanation: Reducing the filter screen diameter gradually increases the filtration efficiency, thereby improving the defluorination efficiency of coking wastewater.

[0012] The beneficial effects of this utility model are:

[0013] (1) The device of this utility model reduces the overall footprint of the treatment equipment by setting up multiple frames that can be stacked and expanded longitudinally as multi-stage treatment chambers for coking wastewater, and makes it easy to store the treatment equipment; and after the first stage of defluorination is completed, the first stage of filtration can be automatically performed and the next stage of defluorination can be entered simply by moving the frame upward.

[0014] (2) The device of this utility model moves the frame upward so that the locking hook is pressed by the trigger plate and disengaged from the hook groove. Under the action of the driving component, the cleaning plate automatically cleans the filter screen corresponding to each stage after each defluorination is completed. By moving the frame downward, the second airbag rod is driven by the first airbag rod to drive the cleaning plate to automatically return to its original position for the next defluorination. This realizes the automatic cleaning of the filter screen and the automatic reset of the cleaning plate. Attached Figure Description

[0021] The present invention will now be described in more detail with reference to specific embodiments, so as to better demonstrate the advantages of the present invention.

[0022] Example 1: A multi-stage defluorination function coking wastewater treatment device, such as... Figure 1 and Figure 2 As shown, it includes a bottom chamber 12, two frames 1 that are sequentially nested from top to bottom and slidably sealed in the bottom chamber 12, and a filter screen 11 set at the bottom of each frame 1. The side wall of the frame 1 is equipped with a temperature and pH adjustment device and a window for applying the agent (not shown in the figure). The adjustment device is a commercially available device. The side wall of the bottom chamber 12 is provided with a discharge port.

[0023] like Figure 1 As shown, both the base 12 and the frame 1 are equipped with a first airbag rod 13 for lifting the frame 1. The first airbag rod 13 is fixed by flanges provided on the top of the base 12 and the frame 1.

[0024] like Figure 2 and Figure 3 As shown, the inner wall of the right side of the frame 1 is provided with a groove 2 and a cleaning plate 21. The inner wall of the frame 1 is provided with a driving component for driving the cleaning plate 21 to move. The cleaning plate 21 is slidably and sealed to the inner wall of the frame 1 and the inner wall of the groove 2. The inner side wall of the left side of the frame 1 is provided with a recycling groove 3 that cooperates with the cleaning plate 21. The driving component is a commercially available electric push rod. The left end of the electric push rod is fixedly connected to the inner wall of the frame 1, and the right end of the electric push rod is fixedly connected to the cleaning plate 21.

[0025] The working principle of the above-mentioned coking wastewater treatment equipment with multi-stage defluorination function is as follows: From top to bottom, the components are, in sequence, the first-stage frame 1, the second-stage frame 1, and the bottom chamber 12. During the first-stage defluorination, the two frames 1 and the bottom chamber 12 are folded. After the first-stage defluorination is completed, the first-stage frame 1 is moved upward, and the first airbag rod 13 of the first stage is stretched, causing the coking wastewater in the first-stage frame 1 to pass through the first-stage filter screen 11 and enter the second-stage frame 1. The reaction precipitate remains on the first-stage filter screen. 11. Once the first-stage frame 1 has moved up until the coking wastewater has completely entered the second-stage frame 1, the electric push rod is activated to drive the first-stage cleaning plate 21 to move, pushing the reaction precipitate on the first-stage filter screen 11 into the first-stage recovery tank 3. After the second-stage defluorination is completed, the first-stage frame 1 is pressed down into the second-stage frame 1 to restore its original position. Then the first airbag rod 13 of the first stage is compressed, and the electric push rod is used to drive the first-stage cleaning plate 21 to reset, thus restoring the entire treatment equipment to its original state.

[0026] Example 2: This example differs from Example 1 in that, as Figure 3 and Figure 4As shown, the driving component is a spring, and the groove 2 is provided with a locking hook 24 connected to the inner wall of the groove 2 by a torsion spring rod. The cleaning plate 21 is provided with a hook groove 23 for engaging with the left end of the locking hook 24. The upper end of the inner wall of the bottom chamber 12 and the frame 1 are both provided with a trigger plate 25 for pressing the right end of the locking hook 24 to disengage the left end of the locking hook 24 from the hook groove 23. The side wall of the frame 1 is provided with a sliding groove for the trigger plate 25 to pass through.

[0027] The working principle of this embodiment differs from that of Embodiment 1 in that, after the first-stage frame 1 moves to its highest point, the other end of the locking hook 24 is pressed by the trigger plate 25, thereby causing one end of the locking hook 24 to lift up and disengage from the hook groove 23, thereby causing the cleaning plate 21 to disengage from the locked state and move under the restoring action of the spring, thus realizing the automatic removal of slag from the first-stage filter screen 11; when the first-stage frame 1 moves down to reset, the operator manually pulls the cleaning plate 21 back to the hook groove 23 and locks it with the locking hook 24, thereby resetting the cleaning plate 21.

[0028] Example 3: This example differs from Example 2 in that, as Figure 5 As shown, the inner wall of the frame 1 is provided with a second airbag rod 22 for driving the cleaning plate 21 to reset. That is, the second airbag rod 22 is fixedly connected to the cleaning plate 21. The air inlet of the second airbag rod 22 is connected to the air outlet of the first airbag rod 13. The air outlet of the second airbag rod 22 and the air inlet of the first airbag rod 13 are both connected to the outside air.

[0029] The working principle of this embodiment differs from that of Embodiment 2 in that, before the first-stage frame 1 moves to its highest point, the first airbag rod 13 expands and elongates due to the engagement and locking of the hook groove 23 and the locking hook 24, causing the interior of the second airbag rod 22 to be under negative pressure. This continues until the first-stage frame 1 moves to its highest point, after which the hook groove 23 disengages from the locking hook 24, and the second airbag rod 22 retracts as the spring returns to its original position. When the first-stage frame 1 moves down to its reset position, the first airbag rod 13 retracts while the second airbag rod 22 expands and elongates, thereby driving the cleaning plate 21 to move until the hook groove 23 and the locking hook 24 re-engage and lock, thus achieving the automatic reset of the cleaning plate 21.

[0030] Example 4: The difference between this example and Example 1 is that the filter diameters of the two filters 11 decrease sequentially from top to bottom. For example, the filter diameter of the first-stage filter 11 is 400 mesh, and the filter diameter of the second-stage filter 11 is 500 mesh.

[0031] The working principle of this embodiment differs from that of Embodiment 1 in that the filter diameter of the filter screen 11 is reduced to gradually improve the filtration efficiency, thereby improving the defluorination efficiency of the coking wastewater.
