When the installation rod is inserted into the through hole, the installation block can be fixed in the installation slot, thereby completing the installation of the bottom filter. After the bottom filter is installed, fill the bottom filter with activated carbon, and then install the top filter on the top of the installation frame through the set positioning bolts, so that the top filter and the bottom filter block the activated carbon. Step 2: Pass the connecting rod through the placement slot so that the connecting rod squeezes the first arc-shaped clamping block and the second arc-shaped clamping block, so that the first arc-shaped clamping block and the second arc-shaped clamping block respectively memorize the second spring and the third spring, so that the connecting rod is located between the first arc-shaped clamping block and the second arc-shaped clamping block, and the connecting rod is fixed by the reaction force of the second spring and the third spring, and at the same time, the second alignment block at the end of the connecting rod is matched and connected with the first alignment block at the end of the fixed rod, and the first alignment block and the second alignment block are fixed by fixing bolts; Step 3, injecting the vitamin K3 waste liquid from the feed pipe into the filter box through the operation panel, and guiding it through the guide plate, and then falling into the filter mechanism, and preventing the vitamin K3 waste liquid from leaking through the side protection plate, and then filtering the vitamin K3 waste liquid through the top filter screen and the activated carbon inside the bottom filter screen, the filtered vitamin K3 waste liquid enters the buffer tank, and enters the reduction box through the discharge port and the discharge pipe, and the chromium (VI) in the waste liquid is reduced by the reducing agent to reduce the chromium (VI) to chromium (III), and then the waste liquid is stirred by the first mixer, so that the chromium (VI) in the waste liquid fully reacts with the reducing agent, and after the reaction, it enters the precipitation box through the first liquid outlet pipe; Step 4: changing the pH value of the waste liquid in the precipitation tank so that the pH value of the waste liquid is between 4 and 6, and then adding hydroxide to the precipitation tank through the precipitation agent inlet to react chromium (III) in the waste liquid with the hydroxide to generate chromium hydroxide precipitate, and stirring the waste liquid by a second stirrer to accelerate the precipitation of chromium hydroxide, at this time, the waste liquid containing the chromium hydroxide precipitate is discharged through the second liquid outlet pipe, and filtered through the filter plate at the bottom of the filter bin, the recovered vitamin K3 waste liquid is discharged from the discharge pipe, and the filter bin is taken out through the taking tank, and the chromium hydroxide precipitate inside the filter bin is recovered, so as to avoid the chromium compound in the vitamin K3 waste liquid from polluting the environment, and the chromium compound in the vitamin K3 waste liquid can be recovered; Step 5.

At this time, you only need to hold the installation frame and release the fixing bolts on the first alignment block and the second alignment block, and then pull it outward to complete the disassembly of the filter mechanism, and then disassemble the bottom filter screen and the top filter screen, and replace the activated carbon.

[0015] The present invention has the following advantages: 1. By providing a mounting mechanism, the bottom filter is placed above the mounting frame and the mounting block is aligned with the mounting slot, and then the pull block is pulled outward to drive the mounting rod to move outward and squeeze the first spring through the slider. When the mounting rod is moved out of the mounting slot, the bottom filter and the mounting seat are moved downward until the mounting block is inserted into the mounting slot, the pull block is released, the first spring rebounds and drives the mounting rod to slide inward along the slide slot through the slider. When the mounting rod is inserted into the through hole, the mounting block can be fixed in the mounting slot, thereby completing the installation of the bottom filter. After the bottom filter is installed, the bottom filter is filled with activated carbon, and then the top filter is installed above the mounting frame through the provided positioning bolts, so that the top filter and the bottom filter block the activated carbon, ensuring that the activated carbon can filter the vitamin K3 waste liquid and remove the insoluble matter in the waste liquid, thereby ensuring the filtering effect and improving the filtering effect of the device on the vitamin K3 waste liquid; Second, by passing the connecting rod through the placement slot, the connecting rod squeezes the first arc-shaped clamping block and the second arc-shaped clamping block, so that the first arc-shaped clamping block and the second arc-shaped clamping block respectively memorize the second spring and the third spring, so that the connecting rod is located between the first arc-shaped clamping block and the second arc-shaped clamping block, and the connecting rod is fixed by the reaction force of the second spring and the third spring, and at the same time, the second alignment block at the end of the connecting rod is matched and connected with the first alignment block at the end of the fixed rod, and the first alignment block and the second alignment block are fixed by fixing bolts to ensure the position of the filter mechanism, making the installation of the filter mechanism more convenient; 3. Start the hydraulic push rod to drive the push plate to move through the output shaft, and the push plate drives the guide rod to move, so that the guide rod slides inside the slide slot, so that the push plate pushes the fixed rod and the connecting rod to move, and then the filter mechanism and the disassembly slot are aligned. At this time, you only need to hold the installation frame and release the fixing bolts on the first alignment block and the second alignment block, and then pull it outward to complete the disassembly of the filter mechanism. Then, disassemble the bottom filter screen and the top filter screen, and replace the activated carbon, which solves the problem of reduced filtering effect due to the difficulty in replacing the filter mechanism. Fourth, inject the vitamin K3 waste liquid from the feed pipe into the filter box, guide it through the guide plate, and then fall into the filter mechanism, prevent the vitamin K3 waste liquid from leaking out through the side protection plate, and then filter the vitamin K3 waste liquid through the top filter screen and the activated carbon inside the bottom filter screen. The filtered vitamin K3 waste liquid enters the buffer tank and enters the reduction box through the discharge port and the discharge pipe. The chromium (VI) in the waste liquid is reduced by the reducing agent to reduce the chromium (VI) to chromium (III), and then the waste liquid is stirred by the first mixer to make the chromium (VI) in the waste liquid fully react with the reducing agent. After the reaction, the waste liquid is stirred by the first mixer. A liquid outlet pipe enters the sedimentation tank, and hydroxide is added to the sedimentation tank through the precipitation agent inlet, so that chromium (III) in the waste liquid reacts with the hydroxide to generate chromium hydroxide precipitate, and the waste liquid is stirred by a second stirrer to accelerate the precipitation of chromium hydroxide. At this time, the waste liquid containing the chromium hydroxide precipitate is discharged through the second liquid outlet pipe and filtered through the filter plate at the bottom of the filter bin. The recovered vitamin K3 waste liquid is discharged from the discharge pipe, and the filter bin is taken out through a taking trough, and the chromium hydroxide precipitate inside the filter bin is recovered, so as to avoid the chromium compound in the vitamin K3 waste liquid from polluting the environment, and the chromium compound in the vitamin K3 waste liquid can be recovered.
