Description

Technical Field

[0001] The present invention belongs to the technical field of wastewater treatment, and particularly relates to a separation and treatment device for wastewater. Background Art

[0002] Nitrochlorobenzene is a kind of chlorinated and nitro-containing aromatic hydrocarbon compound, which is widely used as an intermediate in the production of pharmaceuticals, dyes and pesticides. Wastewater containing nitrochlorobenzene needs to be treated before being discharged.

[0003] In existing wastewater treatment equipment, a filter screen is usually set to filter solid waste in the wastewater. However, a large amount of solid waste will accumulate and block the filter screen during use. As the wastewater treatment progresses, the filter screen will gradually be blocked. If the staff fails to discover and clean it in time, the efficiency will be greatly reduced. Therefore, during the wastewater treatment process, it is necessary for the staff to regularly check the condition of the filter screen, which is rather troublesome. In addition, after the filter screen is blocked, it needs to be manually cleaned and replaced, which is very inconvenient and will further reduce the wastewater treatment efficiency. Therefore, this application proposes a separation and treatment device for wastewater. Summary of the Invention

[0014] In a further technical solution, a material guiding plate is arranged at the bottom inside the acidification box. The upper end surface of the material guiding plate is set as an inclined surface, and the height of the material guiding plate on the side close to the conveying pipe is lower than the height of the material guiding plate on the side away from the conveying pipe.

[0015] In a further technical solution, the pushing mechanism includes a pushing plate, a threaded slider, a moving frame, a lead screw, and a pushing motor. The pushing plate is arranged on the second filter plate, and the lower end surface of the pushing plate is attached to the second filter plate.

In this way, the impurities filtered by the first filter plate will slide down under the action of their own gravity and fall into the interior of the first collection box. The feeding motor inside the feeding mechanism starts, which can drive the lead screw to rotate, and then drive the threaded slider and the moving frame to move along the top plate. The top plate is parallel to the second filter plate, and the feeding plate on the threaded slider moves along the second filter plate, which can push away the impurities filtered from the upper side of the second filter plate and push them into the interior of the neutralization tank, thus completing the cleaning work of the second filter plate. In this way, the cleaning work of the first filter plate and the second filter plate is completed.

[0021] A wastewater separation and treatment device provided by the present invention is provided with a feeding mechanism. The conveying drive device inside the feeding mechanism can drive the conveying rod to rotate, and the conveying rod and the conveying blades rotate, which can push the impurities inside the second collection box to move along the feeding pipe, and then send the impurities in the second collection box into the first collection box. In this way, the mixing of impurities is completed, which is convenient for the subsequent unified treatment of impurities. Description of the Drawings

[0032] The following will describe the detailed implementation manners of the present invention in detail, but it should be understood that the protection scope of the present invention is not limited by the detailed implementation manners.

[0033] As Figures 1 - 8 shown, a wastewater separation and treatment device provided by an embodiment of the present invention includes an acidification tank 1, a first filter screen plate 2, a flipping mechanism 3, a first collection tank 4, a delivery pipe 6, a neutralization tank 8, a second filter screen plate 9, a pushing mechanism 10, and a second collection tank 13.

[0034] Reference can be made to Figures 1 - 3 , the first filter screen plate 2 is arranged in the acidification tank 1, the first collection tank 4 and the neutralization tank 8 are respectively located on both sides of the acidification tank 1, the first filter screen plate 2 is connected to the flipping mechanism 3, and the flipping mechanism 3 is used to rotate the first filter screen plate 2 to make the first filter screen plate 2 tilt towards the side close to the first collection tank 4. In this way, the materials on the first filter screen plate 2 will tilt under the action of gravity and finally enter the interior of the first collection tank 4.

[0035] Specifically, the flipping mechanism 3 includes a flipping base 301, a mounting base 302, a support plate 303, a telescopic rod 304, and a guide plate 305. The flipping base 301 is arranged at one end of the first filter screen plate 2 close to the first collection tank 4. The flipping base 301 is movably connected to the mounting base 302. The mounting base 302 is arranged on the outer wall of the acidification tank 1. The support plate 303 is connected to the side of the first filter screen plate 2 away from the flipping base 301, and there are two support plates 303, which are respectively located on both sides of the first filter screen plate 2. The support plate 303 is movably connected to the output end of the telescopic rod 304, and the other end of the telescopic rod 304 is movably connected to the outer wall of the first collection tank 4. The guide plate 305 is arranged on the side of the first collection tank 4 close to the acidification tank 1. There is an inclined surface on the upper side of the guide plate 305. After the first filter screen plate 2 tilts, the materials on the first filter screen plate 2 slide down under the action of gravity and flow into the interior of the acidification tank 1 along the inclined surface.

[0036] Start the telescopic rod 304. The telescopic rod 304 pulls the support plate 303, and through the support plate 303, pulls the first filter plate 2, causing the first filter plate 2 to rotate around the connection of the flipping seat 301 and the mounting seat 302, so that the first filter plate 2 tilts towards the side close to the acidification tank 1. In this way, the impurities filtered by the first filter plate 2 will slide down under the action of their own gravity and fall into the interior of the first collection box 4.

[0037] It should be noted that at least two baffles 5 are provided at the first collection box 4, and the two baffles 5 are respectively located on both sides of the first collection box 4.

[0038] At the position of the first filter plate 2 in the wastewater channel, after being filtered by the first filter plate 2, it enters the inside of the acidification tank 1, and sulfuric acid is added to acidify the wastewater. After the wastewater is fully acidified, it can be sent to the position of the neutralization tank 8 through the delivery pipe 6.

[0039] It can be referred to Figure 4 、 Figure 5 , one end of the delivery pipe 6 is inserted into the bottom of the acidification tank 1, the other end of the delivery pipe 6 is located above the second filter plate 9, and the delivery pipe 6 is connected to a power pump. The power pump can pump the liquid at the bottom of the acidification tank 1 to the upper side of the second filter plate 9.

[0040] In order to be able to pump the liquid in the acidification tank 1 more labor - saving, a guide plate 7 is provided at the bottom inside the acidification tank 1. The upper end surface of the guide plate 7 is set as an inclined plane, and the height of the guide plate 7 on the side close to the delivery pipe 6 is lower than the height of the guide plate 7 on the side far from the delivery pipe 6.

[0041] Specifically, the second filter plate 9 and the second collection box 13 are both arranged inside the neutralization tank 8. A pushing mechanism 10 is arranged on the second filter plate 9. The pushing mechanism 10 is used to push the impurities filtered on the second filter plate 9 into the second collection box 13.

[0042] More specifically, the pushing mechanism 10 includes a pushing plate 1001, a threaded slider 1002, a moving frame 1003, a lead screw 1004, and a pushing motor 1005. The pushing plate 1001 is arranged on the second filter plate 9. Both the first filter plate 2 and the second filter plate 9 are set in an arc shape, and the lower end surface of the pushing plate 1001 fits with the second filter plate 9. The pushing plate 1001 is connected to the threaded slider 1002. The threaded slider 1002 is thread - connected to the lead screw 1004. The pushing plate 1001 is arranged on the moving frame 1003. The bottom of the moving frame 1003 is provided with a top plate. The top plate is arranged on the outer wall of the neutralization tank 8, and the moving frame 1003 is slidably connected to the top plate. The lead screw 1004 is connected to the inner wall of the neutralization tank 8 through a bearing seat. The output end of the pushing motor 1005 is connected to the lead screw 1004 through a coupling.

[0043] When the pusher motor 1005 inside the pusher mechanism 10 starts, it can drive the lead screw 1004 to rotate, and then drive the threaded slider 1002 and the moving frame 1003 to move along the top plate. The top plate is parallel to the second filter plate 9. The pusher plate 1001 on the threaded slider 1002 moves along the second filter plate 9, and can push away the impurities filtered on the upper side of the second filter plate 9 and push them into the inside of the neutralization tank 8, thus completing the cleaning work of the second filter plate 9.

[0044] In order to prevent the waste water from washing away the impurities on the second filter plate 9, at least two blocking plates 11 are arranged on the upper side of the second filter plate 9. One of the blocking plates 11 is connected with a reset assembly 12. By blocking the two blocking plates 11 on both sides of the second filter plate 9 respectively, the impurities can be prevented from falling off the second filter plate 9.

[0045] At the same time, in order to enable the pusher mechanism 10 to push the impurities on the second filter plate 9 down, the blocking plate 11 is connected with the reset assembly 12. Specifically, the reset assembly 12 includes a square rod 1201, a square tube 1202, and a reset spring 1203. The square rod 1201 is inserted into the square tube 1202, and the square rod 1201 and the square tube 1202 can slide relative to each other. The square tube 1202 is arranged on the inner wall of the neutralization tank 8. The square rod 1201 is connected with the reset spring 1203, and the other end of the reset spring 1203 is connected with the square tube 1202.

[0046] In this way, the pusher mechanism 10 pushes the impurities to the position of the blocking plate 11. After that, the impurities push the blocking plate 11 to move to the side away from the second filter plate 9, and the impurities can fall off the second filter plate 9 and enter the inside of the second collection box 13, completing the cleaning work of the second filter plate 9.

[0047] The waste water entering the neutralization tank 8 is secondarily filtered by the second filter plate 9, and then mixed with the hydrogen peroxide and ferrous sulfate added to the inside of the neutralization tank 8. After oxidation treatment, alkali is added to adjust the pH to neutral to neutralize the pH value of the waste water. In this way, after subsequent biochemical treatment, water that can be directly discharged can be obtained.

[0048] In order to facilitate the unified treatment of impurities, a feeding mechanism 14 is arranged in the second collection box 13. The feeding mechanism 14 communicates with the second collection box 13 and the first collection box 4. The feeding mechanism 14 includes a feeding pipe 1401, a conveying rod 1402, and a conveying driving device 1403. One end of the feeding pipe 1401 is inserted into the second collection box 13, the other end of the feeding pipe 1401 is inserted into the first collection box 4, the conveying rod 1402 is inserted into the inside of the feeding pipe 1401, spiral-distributed blades are welded on the outer side of the conveying rod 1402, and the conveying rod 1402 is connected with the conveying driving device 1403;

[0049] The conveying drive device 1403 can drive the conveying rod 1402 to rotate. The conveying rod 1402 rotates with the conveying blades, and can push the impurities inside the second collection box 13 to move along the feed pipe 1401, and then send the impurities in the second collection box 13 into the first collection box 4. In this way, the mixing of the impurities is completed, which facilitates the subsequent unified treatment of the impurities.

[0050] In summary: The embodiment of the present invention provides a wastewater separation and treatment device. Start the telescopic rod 304. The telescopic rod 304 pulls the support plate 303, and through the support plate 303, pulls the first filter plate 2, so that the first filter plate 2 rotates around the connection of the turning seat 301 and the mounting seat 302, making the first filter plate 2 tilt towards the side close to the acidification tank 1. In this way, the impurities filtered by the first filter plate 2 will slide down under the action of their own gravity and slide into the inside of the first collection box 4.

[0051] The feeding motor 1005 inside the feeding mechanism 10 is started, which can drive the lead screw 1004 to rotate, and then drive the threaded slider 1002 and the moving frame 1003 to move along the top plate. The top plate is parallel to the second filter plate 9. The pushing plate 1001 on the threaded slider 1002 moves along the second filter plate 9, and can push away the impurities filtered from the upper side of the second filter plate 9 and push them into the inside of the neutralization tank 8, thus completing the cleaning work of the second filter plate 9. In this way, the cleaning work of the first filter plate 2 and the second filter plate 9 is completed.

[0052] The feeding mechanism 14 is provided. The conveying drive device 1403 inside the feeding mechanism 14 can drive the conveying rod 1402 to rotate. The conveying rod 1402 rotates with the conveying blades, and can push the impurities inside the second collection box 13 to move along the feed pipe 1401, and then send the impurities in the second collection box 13 into the first collection box 4. In this way, the mixing of the impurities is completed, which facilitates the subsequent unified treatment of the impurities.

[0053] The above discloses only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present invention.
