Description

Technical Field

[0001] The invention belongs to the technical field of sewage purification, in particular to a high-efficiency industrial wastewater purification device and a water purification method thereof. Background Art

[0002] At present, because industrial wastewater contains a large amount of chemical substances and suspended solid impurities, if it is directly discharged, it will have a great impact on the natural environment. This means that industrial wastewater needs to be purified by a sewage treatment plant before it can enter the natural environment; and the purification process of industrial wastewater in a sewage treatment plant generally includes the following steps: First, the wastewater is collected and sent to a screen cleaner to remove large pieces of suspended matter and floating matter. Then, the wastewater enters a grit tank to remove sand and some inorganic matter. Further, the wastewater enters a primary sedimentation tank to achieve preliminary separation of solids and liquids. After treatment in the primary sedimentation tank, the wastewater enters a biochemical tank or biological treatment equipment to decompose organic matter into harmless stable substances and improve water quality. The sewage after biochemical treatment enters a sedimentation tank for further sedimentation treatment. The supernatant after the sedimentation tank enters a disinfection tank to kill bacteria and other microorganisms through disinfection. The disinfected water can be reused or discharged into natural water bodies as needed.

[0003] As part of the sewage purification process, the primary sedimentation tank is an important equipment in the sewage treatment plant for removing suspended matter from sewage. In actual operation, various suspended matter from the influent will accumulate in the primary sedimentation tank to form floating objects, and the presence of these floating objects will affect the discharge water quality after sewage treatment. Therefore, in order to maintain the normal operation of the primary sedimentation tank and ensure the effluent water quality, it is usually necessary to salvage the floating objects in the primary sedimentation tank.

[0004] In the prior art, suspended solid impurities floating on the water surface in the primary sedimentation tank often need to be discharged from the primary sedimentation tank by mechanical salvage. However, the existing mechanical salvage mechanism does not have the function of achieving uninterrupted salvage, so that when encountering a large amount of sewage, a large amount of impurities will accumulate on the rotating baffle in the primary sedimentation tank. These impurities hinder the normal passage of water, causing the water flow speed to slow down, thereby affecting the sedimentation efficiency of the primary sedimentation tank.

[0005] To this end, the present invention provides an industrial wastewater high-efficiency water purification device and a water purification method thereof. Summary of the invention

A curved filter plate 13 is provided on the bracket 11, and a motor 27 is fixedly installed on the side of the baffle plate 6 away from the belt 18. The output end of the motor 27 is fixedly connected to one of the transmission shafts 144. A material guide mechanism is provided on the side of the belt 8 away from the baffle plate 6, and the material guide mechanism is adapted to the curved filter plate 13. A discharge mechanism is provided on the top of the outer wall of the primary sedimentation tank 1, and a scraper assembly is provided in the curved filter plate 13. During operation, when the sewage enters the primary sedimentation tank 1, the baffle plate 6 is driven to rotate slowly by the motor 4 in cooperation with the mounting frame 5, and the impurities floating on the water surface are moved by the rotating baffle plate 6. At this time, the motor 27 is equipped with The transmission shaft 44 drives the belt 8 to operate, so that the arc filter plate 13 moves with the belt 8, and the arc filter plate 13 located below the belt 8 salvages the impurities in front of the baffle plate 6 until the arc filter plate 13 moves to the top of the belt 8, and the impurities in the arc filter plate 13 are discharged into the guide mechanism through the scraper assembly, and then the impurities are transported to the discharge mechanism through the guide mechanism, and finally discharged by the discharge mechanism. The belt 8 cooperates with the arc filter plate 13 to realize the uninterrupted salvage of impurities floating on the water surface of the primary sedimentation tank 1, avoiding the accumulation of a large amount of impurities on one side of the baffle plate 6, and the impurities are discharged by the scraper assembly. The cooperation between the material guiding mechanism and the material discharging mechanism makes it easy to quickly discharge the salvaged impurities from the primary sedimentation tank 1, which effectively solves the problem in the prior art that the suspended solid impurities floating on the water surface in the primary sedimentation tank 1 often need to be discharged from the primary sedimentation tank 1 by mechanical salvage. However, the existing mechanical salvage mechanism does not have the function of achieving uninterrupted salvage, so that when encountering a large amount of sewage, a large amount of impurities will accumulate on the rotating baffle in the primary sedimentation tank 1. These impurities hinder the normal passage of water, causing the water flow speed to slow down, thereby affecting the sedimentation efficiency of the primary sedimentation tank 1.

[0024] A fixed shaft 12 is fixedly connected to the bracket 11, and racks 19 and 10 are respectively arranged on both sides of the belt 8, and the racks 19 and 10 are fixedly connected to the baffle plate 6.

The fitting surfaces of the magnetic rings 11 and 22 are attracted to each other. When working, when the arc filter plate 13 below the belt 8 carries the salvaged debris, When the impurities pass through rack 19, the meshing of spur gear 15 and rack 19 makes the arc filter plate 13 rotate ninety degrees clockwise and then be in an open upward position, which is convenient for the subsequent scraper assembly to discharge the impurities in the arc filter plate 13 into the material guiding mechanism. When the arc filter plate 13 passes through rack 2 10, the meshing of spur gear 15 and rack 2 10 makes the arc filter plate 13 rotate ninety degrees counterclockwise and then reset again, which is convenient for the arc filter plate 13 to move to the bottom of belt 1 8 and then salvage the impurities floating on the water surface. Through the adsorption effect between magnetic ring 1 21 and magnetic ring 2 22, the arc filter plate 13 remains stationary when it does not pass through rack 1 9 and rack 2 10.

[0025] The scraper assembly includes a motor 3 17, a screw 18 and a scraper 20. The motor 3 17 is fixedly installed on one side of the circular plate 14 close to the spur gear 15.

A scraper 20 is fixedly connected to the screw sleeve 19, and the scraper 20 is fitted with the arc filter plate 13. During operation, when the arc filter plate 13 passes through the rack 9 and moves to the material guide mechanism, the motor 3 17 is started, and the motor 3 17 drives the screw 18 to rotate, so that the screw sleeve 19 drives the scraper 20 to move, and then the scraper 20 cleans the impurities in the arc filter plate 13 into the material guide mechanism. Thereafter, the motor 3 17 drives the screw 18 to reverse, so that the scraper 20 is reset, which is convenient for the next scraping and cleaning.

[0026] The material guiding mechanism includes a material guiding trough 24 and an auger 26. A mounting frame 23 is fixedly connected to the side of the material baffle plate 6 close to the belt 8, and a material guiding trough 24 is fixedly connected to the end of the mounting frame 23 away from the material baffle plate 6.

An open groove is provided on the side of the material guiding trough 24 close to the belt 8. During operation, after the scraper 20 pushes the impurities in the arc filter plate 13 into the material guiding trough 24 along the open groove, the auger 26 is driven to rotate by the motor 4 25, so that the auger 26 cleans the impurities in the material guiding trough 24 into the discharging mechanism, which is convenient for discharging the impurities.

[0027] The discharge mechanism includes an annular plate 1 27, an annular plate 28 and a discharge trough 33. The top of the outer wall of the primary sedimentation tank 1 is fixedly connected to an annular plate 1 27, an annular plate 28 is arranged on the outer side of the annular plate 1 27, a connecting rod 29 is evenly fixedly connected between the annular plate 1 27 and the annular plate 28, an annular plate 3 30 is slidably connected to the bottom of the annular plate 1 27 and the annular plate 28, a support plate 31 is evenly fixedly connected to the annular plate 3 30, a discharge trough 33 is fixedly connected to the outer wall of the annular plate 28, and the discharge trough A bracket 2 34 is fixedly connected to the outer wall of 33, a transmission assembly is arranged on the bracket 2 34, and a material discharge assembly is arranged in the discharge trough 33; when working, when impurities are discharged into the space composed of the annular plate 1 27, the annular plate 28 and the annular plate 30 under the action of the auger 26, the annular plate 30 is driven to rotate by the transmission assembly, so that the impurities on the annular plate 30 move along with it until it rotates to the discharge trough 33, and the impurities are completely discharged through the material discharge assembly arranged in the discharge trough 33.

[0028] The unloading assembly includes a belt 2 45, a scraper 2 46 and a transmission shaft 2 47. Two transmission shafts 2 47 are rotatably connected in the discharge trough 33. A belt 2 45 is arranged between the two transmission shafts 2 47, and scrapers 2 46 are evenly fixed on the belt 2 45. During operation, when impurities on the annular plate 30 move to the discharge trough 33, the transmission assembly cooperates with the transmission shaft 2 47 to drive the belt 2 45, so that the scraper 2 46 moves with the belt 2 45, and then the scraper 2 46 scrapes the impurities on the annular plate 30 into the discharge trough 33, and discharges them from the side of the discharge trough 33 away from the annular plate 30, so as to facilitate subsequent centralized processing.

[0029] The transmission assembly includes a motor 5 35, a toothless gear 37, a gear ring 32 and a transmission belt 43. The motor 5 35 is fixedly installed on the bracket 2 34. The output end of the motor 5 35 is fixedly connected to a rotating shaft 1 36, and the toothless gear 37 is fixedly connected to the rotating shaft 1 36. The gear ring 32 is fixedly connected to the annular plate 30, and the gear ring 32 is adapted to the toothless gear 37. The bracket 2 34 is rotatably connected to the rotating shaft 2 38, and the spur gear 2 39 and the bevel gear 1 40 are fixedly connected to the rotating shaft 2 38. The spur gear 2 39 is adapted to the toothless gear 37. One side of the bevel gear 1 40 is meshedly connected to the bevel gear 2 41, and the bevel gear 2 41 is fixedly connected to the rotating shaft 3 42. A transmission belt 43 is arranged between the rotating shaft 3 42 and one of the transmission shafts 2 47. When working, the toothless gear 37 is driven to rotate by the motor 5 35. When the toothless gear 37 is meshed with the gear ring 32, the gear ring 32 is meshed with the bevel gear 2 41. When the gear is closed, the gear ring 32 drives the annular plate three 30 to rotate, so that the two adjacent support plates 31 move to the discharge groove 33. At this time, the toothless gear 37 no longer meshes with the gear ring 32, and begins to mesh with the spur gear two 39, so that the rotating shaft 2 38 drives the bevel gear one 40 to rotate, and then the bevel gear two 41 starts to rotate. The rotating shaft three 42 rotates under the drive of the bevel gear two 41, and cooperates with the transmission belt 43 to drive the transmission shaft two 47 to rotate, so that the belt two 45 drives the scraper two 46 to rotate until the toothless gear 37 is no longer meshed with the spur gear two 39, and the belt two 45 stops moving. In this process, a scraper two 46 located at the connection between the discharge groove 33 and the annular plate two 28 rotates from the top of the belt two 45 to the bottom of the belt two 45, so as to scrape the impurities on the stationary annular plate three 30.

[0030] The top of the annular plate three 30 is curved and matched with the scraper two 46; when working, by designing the top of the annular plate three 30 to be curved and corresponding to the scraper two 46, the scraper two 46 can clean up the impurities accumulated on the annular plate three 30, and the support plates 31 evenly arranged on the annular plate three 30 can effectively prevent some impurities from accumulating on the annular plate three 30 and failing to move to the discharge trough 33.

[0031] Both sides of the arc filter plate 13 are fixedly connected with heightening plates 16; during operation, the heightening plates 16 provided on both sides of the arc filter plate 13 can prevent impurities from falling from the arc filter plate 13 when the arc filter plate 13 passes through the rack 9.

[0032] A water purification method for an industrial wastewater high-efficiency water purification device, the water purification method is applicable to the above-mentioned industrial wastewater high-efficiency water purification device, the water purification method comprises the following steps: S1: When sewage enters the primary sedimentation tank 1, the motor 4 cooperates with the mounting frame 5 to drive the baffle plate 6 to rotate slowly, and the impurities floating on the water surface are moved by the rotating baffle plate 6. At the same time, the upper clean water will flow out from the annular weir plate 2 and enter the space of the primary sedimentation tank 1 outside the annular weir plate 2; S2: Start the motor 2 7, so that the transmission shaft 1 44 drives the belt 1 8 to operate, and then the arc filter plate 13 moves with the belt 1 8. After the arc filter plate 13 moves to the bottom of the belt 1 8, it starts to continuously salvage the impurities in front of the baffle plate 6 until the arc filter plate 13 moves to the top of the belt 1 8, and the impurities in the arc filter plate 13 are scraped into the material guide mechanism through the scraper assembly; S3: The salvaged impurities are transported to the discharge mechanism through the material guide mechanism, and then the impurities are discharged from the primary sedimentation tank 1 through the discharge mechanism.

[0033] Working principle: when sewage enters the primary sedimentation tank 1, the motor 4 cooperates with the mounting frame 5 to drive the baffle plate 6 to rotate slowly, and the rotating baffle plate 6 drives the impurities floating on the water surface to move. At this time, the motor 27 cooperates with the transmission shaft 44 to drive the belt 8 to operate, so that the arc filter plate 13 moves with the belt 8, and the arc filter plate 13 located below the belt 8 salvages the impurities in front of the baffle plate 6 until the arc filter plate 13 moves to the top of the belt 8, and the impurities in the arc filter plate 13 are discharged into the guide mechanism through the scraper assembly, and then the impurities are transported to the discharge mechanism through the guide mechanism, and finally discharged by the discharge mechanism. When the arc filter plate 13 below the belt 8 passes through the rack 9 with the salvaged impurities, the spur gear 15 and the rack 1 9, the arc filter plate 13 is in an upward opening position after rotating ninety degrees clockwise, which is convenient for the subsequent scraping assembly to discharge the impurities in the arc filter plate 13 into the material guide mechanism. After the arc filter plate 13 passes through the rack two 10, the spur gear one 15 is meshed with the rack two 10, so that the arc filter plate 13 is reset again after rotating ninety degrees counterclockwise, which is convenient for the arc filter plate 13 to move to the bottom of the belt one 8 to salvage the impurities floating on the water surface. Through the adsorption effect between the magnetic ring one 21 and the magnetic ring two 22, the arc filter plate 13 remains stationary when it does not pass through the rack one 9 and the rack two 10. When the arc filter plate 13 passes through the rack one 9 and moves to the material guide mechanism, the motor three 17 is started, and the motor three 17 drives the The movable screw 18 rotates, so that the screw sleeve 19 drives the scraper 20 to move, and then the scraper 20 cleans the impurities in the arc filter plate 13 into the material guide mechanism. Thereafter, the motor 3 17 drives the screw 18 to reverse, so that the scraper 20 is reset, which is convenient for the next scraping and cleaning. When the scraper 20 pushes the impurities in the arc filter plate 13 into the material guide trough 24 along the opening groove, the motor 4 25 drives the auger 26 to rotate, so that the auger 26 cleans the impurities in the material guide trough 24 into the discharge mechanism, which is convenient for the discharge of impurities. When the impurities are discharged into the space formed by the annular plate 1 27, the annular plate 28 and the annular plate 30 under the action of the auger 26, the motor 5 35 drives the toothed gear 37 to rotate. When the toothed gear 37 meshes with the gear ring 32, the toothed gear 37 is driven to rotate. When the gear ring 32 is engaged, the ring plate 30 is driven by the gear ring 32 to rotate, so that the two adjacent support plates 31 move to the discharge groove 33. At this time, the toothless gear 37 is no longer meshed with the gear ring 32, and begins to mesh with the spur gear 2 39, so that the rotating shaft 2 38 drives the bevel gear 1 40 to rotate, and then the bevel gear 2 41 starts to rotate. The rotating shaft 3 42 rotates under the drive of the bevel gear 2 41, and cooperates with the transmission belt 43 to drive the transmission shaft 2 47 to rotate, so that the belt 2 45 drives the scraper 2 46 to rotate, until the toothless gear 37 is no longer meshed with the spur gear 2 39, and the belt 2 45 stops moving. In this process, a scraper 2 46 located at the connection between the discharge groove 33 and the ring plate 28 rotates from the top of the belt 2 45 to the bottom of the belt 2 45.To scrape away the impurities on the stationary annular plate 30, the top of the annular plate 30 is designed to be an arc surface and correspond to the scraper 2 46, so that the scraper 2 46 can clean the impurities accumulated on the annular plate 30, and the support plates 31 evenly arranged on the annular plate 30 can effectively prevent some impurities from accumulating on the annular plate 30 and not moving to the discharge groove 33.
