Wastewater denitrification device

Abstract

This utility model discloses a wastewater denitrification device, relating to the field of wastewater denitrification technology. It includes a fixed base with a fixed cavity on its front side wall. A filter barrel is installed within the fixed cavity, and filter holes are evenly distributed on the bottom wall of the filter barrel. A through groove is formed at the top of the fixed base, and a cylindrical body connected to the filter barrel is installed within the through groove. A shell is installed around the cylindrical body. This utility model's design, with its fixed cavity on the front side wall of the fixed base, allows sediment from the wastewater to be contained within the filter barrel. Wastewater then flows into a drain trough and is discharged. After all wastewater is drained, the lid rises, separating the cylindrical body from the filter barrel. At this point, workers can remove the filter barrel from the fixed cavity for cleaning, preventing sediment from clogging the filter holes and affecting the filtration speed, thus ensuring the efficiency of desulfurization and denitrification.

Description

Technical Field

[0001] This utility model relates to the field of wastewater denitrification technology, and in particular to a wastewater denitrification device. Background Technology

[0002] In modern processes, some industrial wastewater contains a large amount of sulfur and nitrate compounds. In order to purify such wastewater and ensure its rational discharge, it is necessary to carry out desulfurization and denitrification treatment. The commonly used treatment method is to add the required flocculant and catalyst to the wastewater to cause the S and N elements to precipitate out. Then, the precipitate and the remaining wastewater can be treated separately.

[0003] After wastewater treatment and filtration, existing wastewater denitrification devices leave sediment inside, making it inconvenient for staff to clean the inside of the device. When used again, the sediment remaining on the surface of the filter screen and the inner wall of the filter box can block some of the filter screen pores, resulting in a decrease in filtration speed and affecting the efficiency of desulfurization and denitrification. Utility Model Content

[0004] In order to overcome the above-mentioned defects in the prior art, this utility model provides a wastewater denitrification device.

[0023] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0024] according to Figure 1-6 As shown, a wastewater denitrification device includes a fixed base 1, a fixed cavity 101 on the front side wall of the fixed base 1, a filter barrel 2 installed in the fixed cavity 101, filter holes 201 evenly distributed on the bottom wall of the filter barrel 2, a through groove 102 on the top of the fixed base 1, a cylinder 3 connected to the filter barrel 2 installed in the through groove 102, a cylinder shell 4 installed around the cylinder 3, a barrel cover 5 installed on the top of the cylinder shell 4 that can be raised and lowered, the cylinder 3 fixedly installed at the bottom of the barrel cover 5, a stirring mechanism provided on the barrel cover 5, a base 6 fixedly installed at the bottom of the fixed base 1, a water trough 601 provided inside the base 6, a first baffle 7 rotatably installed on the top of the water trough 601, a second baffle 8 movably installed on the top of the first baffle 7, the second baffle 8 fixedly installed at the bottom of the fixed base 1, and a driving mechanism for driving the first baffle 7 to rotate is provided on the rear side wall of the base 6.

[0025] In this embodiment, the bottom end of the cylinder 3 is provided with a connecting platform 301, and the top end of the filter barrel 2 is provided with an insertion groove 202 that matches the connecting platform 301. A sealing ring 302 is installed on the side wall of the connecting platform 301. When the cylinder 3 and the filter barrel 2 are connected together, the connecting platform 301 is inserted into the insertion groove 202, and the connection is sealed by the sealing ring 302, so that a closed reaction chamber is formed between the cylinder 3 and the filter barrel 2.

[0026] In this embodiment, the stirring mechanism includes a stirring rod 19, which is rotatably mounted at the bottom center of the bucket cover 5. A second motor 20 is fixedly mounted on the top of the bucket cover 5 via a motor bracket. The power output shaft of the second motor 20 is connected to the rotating shaft of the stirring rod 19. Two sets of feeding pipes 21 are fixedly mounted on the bucket cover 5, and the two sets of feeding pipes 21 are respectively connected to the inner cavity of the cylinder 3. When the equipment is working, wastewater and additives are injected into the inner cavity of the cylinder 3 through the feeding pipes 21. The stirring rod 19 is driven to rotate by the second motor 20, thereby accelerating the mixing of wastewater with flocculant and catalyst and improving the reaction rate.

[0027] In this embodiment, the driving mechanism includes a first motor 9. A mounting groove 602 is provided on the rear side wall of the base 6, and the first motor 9 is fixedly installed in the mounting groove 602. A first bevel gear 10 is fixedly installed on the power output shaft of the first motor 9. A second bevel gear 11 is fixedly installed on the side wall of the first baffle plate 7. The first bevel gear 10 and the second bevel gear 11 mesh with each other. Several sets of first drainage holes 701 are evenly arranged on the first baffle plate 7, preferably three sets. A second drainage hole 801 matching the first drainage holes 701 is provided on the second baffle plate 8. A sealing gasket 802 is fixedly installed at the bottom edge of the second drainage hole 801, and the sealing gasket 802 abuts against the top wall of the first baffle plate 7. This allows for the mixing of wastewater and flocculant. When the catalyst is mixed, the first drain hole 701 and the second drain hole 801 are staggered. The connection between the first baffle plate 7 and the second baffle plate 8 is sealed by the sealing gasket 802, thereby isolating the wastewater above the second baffle plate 8. As the reaction proceeds, S and N elements precipitate from the wastewater to form precipitates. After the reaction is completed, the first motor 9 drives the first bevel gear 10 to rotate. With the cooperation of the first bevel gear 10 and the second bevel gear 11, the first baffle plate 7 and the second baffle plate 8 rotate relative to each other, so that the first drain hole 701 and the second drain hole 801 are aligned with each other, thereby connecting the filter bucket 2 with the drain trough 601, allowing the wastewater to enter the drain trough 601, while the precipitates are isolated in the filter bucket 2, thus separating the precipitates from the wastewater.

[0028] In this embodiment, a sewage discharge pipe 12 is fixedly installed on the side wall of the base 6, and a water valve 13 is installed on the sewage discharge pipe 12. The sewage discharge pipe 12 is connected to the inside of the drainage trough 601. By opening the water valve 13, sewage is discharged from the inside of the equipment.

[0029] In this embodiment, several sets of guide frames 14 are fixedly installed on the top of the side wall of the outer shell 4. Guide rods 15 are slidably installed on the guide frames 14. The guide rods 15 are fixedly installed at the bottom edge of the lid 5. A hydraulic cylinder 16 is fixedly installed on the rear side wall of the outer shell 4. The power output shaft of the hydraulic cylinder 16 is connected to the lid 5. A door 17 is movably installed on the front side of the fixed cavity 101. A handle 18 is fixedly installed on the side of the filter bucket 2 near the door 17. When the filter bucket 2 needs to be removed for cleaning, the lid 5 is driven to rise along the guide rods 15 by the hydraulic cylinder 16, so that the outer shell 3 and the filter bucket 2 are separated from each other. At this time, the staff opens the door 17 on the front side of the fixed cavity 101 and pulls the filter bucket 2 out of the fixed cavity 101 for cleaning by using the handle 18.

[0030] In use, before wastewater treatment begins, the cylinder 3 and filter barrel 2 are installed together, with the drain holes on the first baffle plate 7 and the second baffle plate 8 interlaced, forming a sealed reaction chamber between the cylinder 3 and the filter barrel 2. Wastewater and additives are injected into the reaction chamber through the feed pipe 21. Then, the second motor 20 is started, and the stirring rod 19 rotates under the drive of the second motor 20, thereby accelerating the mixing of wastewater with flocculant and catalyst and increasing the reaction rate. As the reaction proceeds, sulfur and nitrogen elements precipitate from the wastewater to form precipitates. After the reaction is complete, the first motor 9 drives the first baffle plate... 7. Rotate the filter 701 to align the first drain hole 701 with the second drain hole 801, thereby connecting the filter 2 with the drain trough 601. This allows wastewater to enter the drain trough 601, while the sediment remains isolated in the filter 2, thus separating the sediment from the wastewater. After all the wastewater has been drained, the hydraulic cylinder 16 drives the cover 5 to rise, separating the cylinder 3 from the filter 2. At this time, the operator opens the door 17 on the front side of the fixed cavity 101 and pulls the filter 2 out of the fixed cavity 101 to facilitate cleaning of the filter 2. This prevents sediment from clogging the filter holes 201, affecting the filtration speed, and thus ensuring the efficiency of desulfurization and denitrification.
