Description

Technical Field

[0001] This utility model relates to the field of sulfur-containing wastewater treatment, specifically a filtration mechanism for sulfur-containing wastewater treatment. Background Technology

[0002] With the development of my country's industrial modernization, the scale of industrial production is constantly expanding, and the amount of wastewater generated in the process of industrial production is also increasing. Wastewater contains sulfides, nitrogen oxides, and metal compounds. Sulfides in wastewater are toxic and corrosive, and direct discharge into the external environment will cause pollution. Therefore, wastewater needs to be treated before discharge to remove sulfides. The treatment of sulfides in wastewater includes filtration, which is to remove large particulate impurities from the wastewater. This prevents large sulfur-containing solids and other large particulate impurities from affecting the formation of chemical reactions when directly extracting sulfides from sulfur-containing wastewater through chemical treatment. Consequently, the sulfides in the sulfur-containing wastewater cannot be completely extracted, affecting the treatment of sulfur-containing wastewater. Therefore, filtration is beneficial for subsequent chemical treatment of sulfur-containing wastewater.

[0003] According to Chinese Patent No. CN216653675U, a sulfur-containing wastewater treatment device is disclosed. In use, sulfur-containing wastewater is added into the filtration mechanism through the wastewater inlet on the tank cover. The external power supply of the motor is turned on, which drives the mounting frame to rotate rapidly. Under the action of centrifugal force, the sludge is thrown to the side of the filtration mechanism, allowing the wastewater to pass smoothly through the middle part of the filtration mechanism. When the filtration mechanism is blocked, the wastewater in the mounting frame cannot be discharged, causing the weight to gradually increase. When the weight is large enough, the support frame triggers a pressure switch, causing the buzzer to sound, reminding the staff to clean it in time.

[0004] Regarding the aforementioned patent content, a filter screen is used to filter sulfur-containing wastewater. However, after prolonged filtration, a significant amount of impurities accumulate on the filter surface. Cleaning this accumulation requires first unscrewing the bolts on the cover, then removing the cover, followed by unscrewing the bolts between the filter frame and the mounting bracket to release the filter frame's constraint. Only then can the filter frame be removed and the impurities cleaned. After cleaning, the reverse steps must be repeated: first, the filter frame is bolted onto the mounting bracket, and then the cover is bolted back onto the bracket. The filter screen frame can only be installed on the treatment box in this way. However, the disassembly and cleaning process is quite troublesome, requiring multiple disassembly and reassembly of the bolts, which is time-consuming and labor-intensive. When the filter screen frame continuously filters sulfur-containing wastewater, sulfur-containing wastewater residue will inevitably remain on the filter screen frame. When the staff removes the filter screen frame, their hands may come into contact with the wastewater residue on the filter screen frame. The sulfides and other chemicals in sulfur-containing wastewater are irritating and corrosive. Contact with them can cause irritation symptoms such as itching, redness, and burning on the skin, which may damage the hands and reduce the cleaning efficiency of the impurities accumulated on the filter screen. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a filtration mechanism for treating sulfur-containing wastewater, so as to solve the technical problem of the inconvenience of cleaning the impurities accumulated on the filter screen.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filtration mechanism for treating sulfur-containing wastewater, comprising a device body, a first motor mounted on the upper side of one side of the device body, and the output end of the first motor connected to a drive shaft extending into the interior of the device body, a frame mounted on one end of the drive shaft, and a filter screen mounted inside the frame, inclined plates mounted on both sides of the interior of the device body, a discharge port opened on the lower side of one side of the device body, a sealing plate mounted on one side of the device body via a hinge, a second motor mounted on the lower outer surface of the device body, and the output end of the second motor connected to a movable shaft extending into the discharge port, a guide plate mounted on the outer wall of the movable shaft, two guide rods mounted on the upper interior of the device body, and a slide seat sleeved on the outer wall of the guide rods, an air guide pipe mounted on the bottom of the slide seat, multiple nozzles mounted on the bottom of the air guide pipe, and a flexible air supply hose extending to the outside of the device body connected to one side of the air guide pipe.

[0007] By adopting the above technical solution, the filter screen can filter impurities in sewage. When it is necessary to clean the impurities accumulated on the top of the filter screen, sewage is no longer added to the main body of the device. Then, the staff starts the first motor, which drives the drive shaft to rotate, thereby driving the frame to rotate.

[0008] Furthermore, a hydraulic cylinder is installed on the upper side of the other side of the main body of the device, and the output end of the hydraulic cylinder is fixedly connected to the slide block through the piston rod, and the slide block is slidably connected to the guide rod.

[0009] By adopting the above technical solution, the operation of the hydraulic cylinder can extend the piston rod, thereby driving the slide to move, which in turn drives the air guide pipe to move and the nozzle to move.

[0010] Furthermore, a sealing gasket is installed on one side of the sealing plate, and a hanging ring is fixed on the other side of the sealing plate. The sealing gasket is located inside the discharge port and is in contact with the inner wall of the discharge port.

[0011] By adopting the above technical solution, once the sealing gasket is inserted into the discharge port, the discharge port can be sealed to prevent sewage from leaking out.

[0012] Furthermore, a sealing strip is installed on the outer wall of the frame, and the outer wall of the sealing strip is in contact with the inner wall of the device body.

[0013] By adopting the above technical solution, the sealing strip can improve the sealing performance between the frame and the main body of the device.

[0014] Furthermore, the top of the main body of the device is connected to an inlet pipe, and the bottom of the main body of the device is connected to an outlet pipe.

[0015] By adopting the above technical solution, the inlet pipe is designed so that sulfur-containing wastewater can enter the interior of the main body of the device, while the outlet pipe is designed so that the filtered wastewater can be discharged.

[0016] Furthermore, a pull rope is connected to the other side of the main body of the device, and a hook is installed at the bottom end of the pull rope.

[0017] By adopting the above technical solution, it is easier for staff to hang the hanging ring with a hook.

[0018] Furthermore, a rotating shaft is connected to one side of the frame, and one end of the rotating shaft is connected to the inner wall of the device body through a sealed bearing.

[0019] By adopting the above technical solution, the frame can rotate, thereby improving the stability of the frame during rotation.

[0020] Furthermore, the top of the inclined plate and the top of the guide plate are both smooth, and the outer surface and back of the guide plate are in contact with the inner wall of the main body of the device and the inner wall of the discharge port.

[0021] By adopting the above technical solution, the inclined plate can guide the sewage, allowing the sewage to flow smoothly onto the guide plate.

[0022] Furthermore, the inclined plate is located below the filter screen, the guide plate is located below the inclined plate, and a support frame is installed at the bottom of the main body of the device.

[0023] By adopting the above technical solution, the support frame can support the main body of the device, while the guide plate can guide the sewage.

[0024] Furthermore, a control panel is mounted on the outer surface of the main body of the device, and the control panel is electrically connected to the first motor, the second motor and the hydraulic cylinder respectively.

[0025] By adopting the above technical solution, the first motor, the second motor, and the hydraulic cylinder can be started or stopped via the control panel.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model comprises a first motor, a drive shaft, a frame, a sealing plate, a guide plate, an inclined plate, a discharge port, a second motor, and a movable shaft. When it is necessary to clean the impurities accumulated on the top of the filter screen, wastewater is no longer added to the main body of the device. Then, the operator pulls the sealing plate to rotate via the hanging ring. After the sealing plate and the sealing gasket rotate and open, they no longer block the discharge port. Next, the second motor is started, which drives the movable shaft to rotate counterclockwise, and also drives the guide plate to rotate counterclockwise. When the guide plate contacts the bottom of the right inclined plate, the second motor is turned off and the first motor is started. The first motor drives the drive shaft. The rotation causes the frame to rotate. When the frame rotates 180°, the first motor is turned off, and the impurities on the filter screen fall down onto the inclined plate, then slide down onto the guide plate. The particulate impurities are then discharged from the discharge port through the guide plate. This method can quickly clean the impurities accumulated on the filter screen. Moreover, this method eliminates the need to remove the cover plate and then the filter screen to clean the impurities on the filter screen, thus simplifying the cleaning process. It also prevents workers from touching the filter screen and coming into contact with the wastewater remaining on the filter screen, thereby improving safety and increasing the efficiency of cleaning impurities on the filter screen.

[0028] 2. This utility model is equipped with a hydraulic cylinder, an air supply hose, an air guide pipe, a nozzle, a slide, and a guide rod. When the filter screen rotates 180°, the operator can also start the hydraulic cylinder and an external air compressor. Compressed air enters the air guide pipe through the air supply hose and is sprayed out through the nozzle to clean the filter screen. At the same time, the operation of the hydraulic cylinder can extend the piston rod, thereby moving the slide, which in turn moves the air guide pipe and the nozzle, thereby improving the cleaning efficiency of the filter screen and allowing impurities to fall down smoothly, further improving the cleaning efficiency of the filter screen. The guide rod can guide the slide and the air guide pipe, thereby improving the stability of the air guide pipe when it moves.

[0029] 3. This utility model is equipped with a pull rope, hook and hanging ring. After the sealing plate and sealing gasket are rotated out of the discharge port, the operator can hang the hanging ring with the hook to prevent the sealing plate and sealing gasket from resetting and rotating. This avoids the sealing plate blocking the discharge port when impurities are discharged from the discharge port, thus affecting the discharge efficiency of impurities and allowing impurities to be discharged smoothly through the discharge port.

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] The embodiments of this utility model will be described below based on its overall structure.

[0041] Example 1:

[0042] A filtration mechanism for treating sulfur-containing wastewater, such as Figures 1-8 As shown, the device includes a main body 1. A first motor 3 is installed on the upper side of one side of the main body 1, and the output end of the first motor 3 is connected to a drive shaft 4 extending into the interior of the main body 1. A frame 5 is installed at one end of the drive shaft 4, and a filter screen 6 is installed inside the frame 5. Inclined plates 14 are installed on both sides of the interior of the main body 1. A discharge port 26 is opened on the lower side of one side of the main body 1. A sealing plate 18 is also installed on one side of the main body 1 via a hinge. A second motor 23 is installed on the lower outer surface of the main body 1, and the output end of the second motor 23 is connected to a movable shaft 20 extending into the discharge port 26. The filter screen 6 can filter impurities in the sewage. When it is necessary to clean the impurities accumulated on the top of the filter screen 6, sewage is no longer added to the main body 1. Then, the operator starts the first motor 3, which drives the drive shaft 4 to rotate, thereby driving the frame 5 to rotate. The filter screen 6 and the frame 5 are both made of stainless steel. A glass window 27 is also installed on the outer surface of the main body 1 to observe the amount of impurities accumulated on the filter screen 6.

[0043] See Figures 1-6 A guide plate 22 is installed on the outer wall of the movable shaft 20. Two guide rods 8 are installed on the upper part of the inner side of the device body 1. A slide 9 is sleeved on the outer wall of the guide rods 8. A gas duct 10 is installed at the bottom of the slide 9. Multiple nozzles 11 are installed at the bottom of the gas duct 10. A gas delivery hose 12 extending to the outside of the device body 1 is connected to one side of the gas duct 10. The gas delivery hose 12 is connected to an external air compressor so that compressed air can enter the interior of the gas duct 10 through the gas delivery hose 12. A liquid inlet pipe 7 is connected to the top of the device body 1. A liquid outlet pipe 2 is connected to the bottom of the device body 1. The liquid inlet pipe 7 is set so that sulfur-containing wastewater can enter the interior of the device body 1. The liquid outlet pipe 2 is set so that the filtered wastewater can be discharged. A sealing gasket 21 is installed on one side of the sealing plate 18. The sealing gasket 21 is made of fluororubber material. A hanging ring 19 is fixed on the other side of the sealing plate 18.

[0044] Specifically, the sealing gasket 21 is located inside the discharge port 26, and the outer wall of the sealing gasket 21 is in contact with the inner wall of the discharge port 26. When the sealing gasket 21 is rotated into the discharge port 26, it can seal the discharge port 26 to prevent sewage from leaking from the discharge port 26. A hydraulic cylinder 13 is installed on the upper side of the other side of the main body 1, and the output end of the hydraulic cylinder 13 is fixedly connected to the slide 9 through the piston rod. The slide 9 is slidably connected to the guide rod 8. The distance between the two guide rods 8 is greater than the diameter of the inlet pipe 7. When the hydraulic cylinder 13 works, the piston rod can be extended, thereby driving the slide 9 to move. The slide 9 then drives the air guide pipe 10 to move and drives the nozzle 11 to move. A rotating shaft 15 is connected to one side of the frame 5, and one end of the rotating shaft 15 is connected to the inner wall of the main body 1 through a sealed bearing. When the frame 5 rotates, it can drive the rotating shaft 15 to rotate, thereby improving the stability of the frame 5 when rotating.

[0045] See Figures 1-7 The tops of the inclined plate 14 and the guide plate 22 are both smooth. The outer surface and back of the guide plate 22 are in contact with the inner wall of the main body 1 and the inner wall of the discharge port 26. The inclined plate 14 can guide the sewage, allowing it to flow smoothly onto the guide plate 22. The inclined plate 14 is located below the filter screen 6. The guide plate 22 is rotatably connected to the main body 1 via a movable shaft 20. The guide plate 22 is located below the inclined plate 14. A support frame is installed at the bottom of the main body 1 to support it, while the guide plate 22 can guide the sewage. Wastewater is diverted. A control panel 24 is installed on the outer surface of the main body 1 of the device. The control panel 24 is electrically connected to the first motor 3, the second motor 23 and the hydraulic cylinder 13 respectively, so that the first motor 3, the second motor 23 and the hydraulic cylinder 13 can be started or stopped through the control panel 24. The distance between the nozzle 11 and the frame 5 is greater than half the width of the frame 5. The distance between the top of the inclined plate 14 and the frame 5 is greater than half the width of the frame 5, so as to avoid the inclined plate 14 and the nozzle 11 from obstructing the rotation of the frame 5, so that the frame 5 can rotate smoothly.

[0046] Example 2:

[0047] Based on the above embodiment 1, in order to improve the sealing between the frame 5 and the inner wall of the device body 1, the following structure will be set.

[0048] Specifically, a sealing strip 25 is installed on the outer wall of the frame 5. The sealing strip 25 is made of fluororubber material and fits against the inner wall of the device body 1. The sealing strip 25 can improve the sealing between the frame 5 and the device body 1.

[0049] Example 3:

[0050] Based on the above embodiment 1, in order to prevent the sealing plate 18 and the sealing gasket 21 from resetting and rotating when impurities are discharged through the discharge port 26, the following structure will be set.

[0051] See Figures 1-4 On the other side of the main body 1 of the device, there is a pull rope 16, and a hook 17 is installed at the bottom of the pull rope 16. When the sealing plate 18 and the sealing gasket 21 are rotated out of the discharge port 26, the operator can hang the hanging ring 19 through the hook 17 to prevent the sealing plate 18 and the sealing gasket 21 from resetting and rotating, so as to avoid the sealing plate 18 blocking the discharge port 26 when impurities are discharged from the discharge port 26 and affecting the discharge efficiency of impurities.

[0052] The working principle of this utility model is as follows: First, when using it, the power can be turned on, and then the sulfur-containing wastewater is injected into the interior of the main body 1 of the device through the inlet pipe 7. After the wastewater flows to the filter screen 6, the impurities in the wastewater can be filtered. The filtered wastewater will continue to flow downward and flow to the inclined plate 14, then to the guide plate 22, and then flow into the bottom of the main body 1 of the device through the guide plate 22 and be discharged through the drain pipe 2.

[0053] When it is necessary to clean the impurities accumulated on the top of the filter screen 6, no more sewage is injected into the main body 1 of the device. Then, the staff places the impurity collection box next to the device, with the top of the impurity collection box lower than the bottom of the discharge port 26. Next, the sealing plate 18 is rotated by pulling the hanging ring 19. After the sealing plate 18 and the sealing gasket 21 rotate and open, they no longer block the discharge port 26. At the same time, the staff can hang the hanging ring 19 with the hook 17 to prevent the sealing plate 18 and the sealing gasket 21 from resetting and rotating. Then, the second motor 23 is started, and the second motor 23 works. The drive shaft 20 can rotate counterclockwise, and drive the guide plate 22 to rotate counterclockwise. When the guide plate 22 contacts the bottom of the right inclined plate 14, the second motor 23 is turned off and the first motor 3 is started. The first motor 3 can drive the drive shaft 4 to rotate, and then drive the frame 5 to rotate. When the frame 5 rotates 180°, the first motor is turned off, and the impurities on the filter screen 6 will fall down onto the inclined plate 14, and then slide down onto the guide plate 22. Then the particulate impurities are discharged from the discharge port 26 through the guide plate 22 and fall into the impurity collection box.

[0054] Meanwhile, the staff can also start the hydraulic cylinder 13 and the external air compressor. Compressed air enters the air guide pipe 10 through the air supply hose 12 and is sprayed out through the nozzle 11 to clean the filter screen 6. At the same time, the operation of the hydraulic cylinder 13 can extend the piston rod, thereby driving the slide 9 to move, and then driving the air guide pipe 10 and the nozzle 11 to move, thereby improving the cleaning efficiency of the filter screen 6, allowing impurities to fall down smoothly, and further improving the cleaning efficiency of the filter screen 6.

[0055] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
