Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a deodorization device for coking wastewater. Background Technology

[0002] Coking wastewater is a typical toxic and difficult-to-degrade organic wastewater, mainly from the initial cooling of coke oven gas and the production water and steam condensation wastewater in the coking process. Polycyclic aromatic hydrocarbons in coking wastewater are not only difficult to degrade, but are also usually strong carcinogens, causing serious pollution to the environment and directly threatening human health. Therefore, wastewater treatment is necessary.

[0003] The prior art patent document CN218781154U provides a deodorization device for coking wastewater, including a rotating cylinder. Wastewater enters the interior of a separating plate through an inlet pipe, and after being separated by the separating plate, it falls into a groove on the rotating cylinder. A motor is started to drive the rotating cylinder to rotate, thereby driving the groove to rotate. During the rotation of the groove, a large amount of wastewater accumulates. At the same time, a deodorizing agent is connected to an external pipe. The deodorizing agent enters the inlet cylinder and is discharged into the groove through an outlet nozzle. The deodorizing agent is discharged through the outlet nozzle during the process of wastewater accumulation in the rotating groove, which increases the contact time between the wastewater and the deodorizing agent during the rotation process, improves the effectiveness of the deodorizing agent, and enhances the mixing effect of the wastewater and the deodorizing agent.

[0004] Although the device has many beneficial effects, the following problems still exist: during the use of the device, the mixing of wastewater and deodorizing agent is not sufficient due to the unidirectional rotation of the stirring rod, resulting in poor deodorization effect; secondly, after long-term use, sludge accumulates and causes blockage, which needs to be improved. In view of this, we propose a deodorization device for coking wastewater. Utility Model Content

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a coking wastewater deodorization device, including:

[0035] Please see Figures 1-5This embodiment of a coking wastewater deodorization device includes a tank 1, with an inlet 2 welded to the top of the tank 1 and a feed pipe 3 welded to the top of the outer circumference of the tank 1. An agitator 4 is fixed inside the tank 1, including a motor 401. A sleeve 402 is fixed to the output end of the motor 401, and a crown gear 403 is fixed to the top of the sleeve 402. The crown gear 403 meshes with a gear 404, and another crown gear 403 meshes with the top of the gear 404. Another sleeve 402 is fixed to the top of the other crown gear 403. A connecting shaft 405 is fixed to the inner circumference of the gear 404, and a mounting bracket 406 is rotatably connected to the other end of the connecting shaft 405. Both ends of the mounting bracket 406 are fixed to the sleeve 402. The bearing 407 on the outer circumference of the 02 sleeve is fixed with multiple stirring blades 408. An aeration component 5 is fixed at the bottom of the inner cavity of the tank 1. A water outlet pipe 6 is welded to the bottom of the outer circumference of the tank 1. The motor 401 is electrically connected to an external power source. Sewage is input through the inlet 2 and deodorizer is added through the feed pipe 3. When the motor 401 is turned on, the sleeve 402 is rotated, which causes the crown gear 403 to drive the gear 404 to rotate. Then, another crown gear 403 drives another sleeve 402 to rotate in the opposite direction. Adjacent sleeves 402 drive the stirring blades 408 to rotate in the opposite direction, which makes it easier to mix the sewage and deodorizer more thoroughly. The sewage after deodorization is discharged from the water outlet pipe 6.

[0036] It is worth noting that, in order to prevent the gear 404 from rotating, the aeration assembly 5 specifically includes an air supply pipe 501. A first valve 502 is fixedly installed on the outer circumference of the air supply pipe 501. A distribution pipe 503 is fixedly installed at the other end of the air supply pipe 501. Multiple branch pipes 504 are fixedly installed on the side wall of the distribution pipe 503. Multiple aerators 505 are fixedly installed on the top of the outer circumference of the branch pipes 504. By opening the first valve 502, gas is transported from the air supply pipe 501 to the distribution pipe 503. The gas is evenly distributed into the interior of the multiple branch pipes 504 through the distribution pipe 503. The gas is diffused and escaped in the form of bubbles through the aerators 505, which avoids the accumulation of sludge and prevents blockage.

[0037] Next, in order to improve stability, specifically, a fixed shaft 409 is rotatably connected to the inner circumference of the sleeve 402, and a connecting rod 410 located on the inner circumference of the tank body 1 is fixed at the top of the outer circumference of the fixed shaft 409. The connecting rod 410 makes the fixed shaft 409 more stable and prevents multiple sleeves 402 from falling apart.

[0038] Meanwhile, to prevent sewage from flowing back into aerator 505, specifically, aerator 505 is a rubber diaphragm microporous aerator with tiny self-closing pores on the diaphragm. Under air pressure, the micropores of aerator 505 will automatically open, allowing air to enter tank 1 for oxygenation. If the pressure disappears, the micropores of aerator 505 will automatically close, preventing sewage from flowing back into the micropores.

[0039] Furthermore, to avoid waste due to excessive deodorant, a distribution plate 7 is fixed at the bottom of the inlet 2, and a second valve 8 is fixed on the outer circumference of the feed pipe 3. The distribution plate 7 facilitates the even distribution of wastewater into the tank 1, and the second valve 8 facilitates the control of the input amount of deodorant.

[0040] It is worth noting that, in order to make the deodorant added more evenly, a storage tank 9 located on the inner circumference of the tank 1 is welded to one end of the feed pipe 3. Multiple through holes 10 are opened on the inner circumference of the storage tank 9. The deodorant enters the storage tank 9 through the through holes 10, which facilitates the even dispersion of the deodorant.

[0041] Finally, to prevent sewage from entering the storage tank 9, specifically, multiple movable rods 11 are slidably connected to the inner circumference of the storage tank 9. A baffle 12 is fixed at one end of each movable rod 11, and a spring 13 is fixed on the outer circumference of the movable rod 11. By inputting deodorizing agent, the baffle 12 is squeezed, causing the movable rod 11 to move the baffle 12. When the deodorizing agent is stopped, the spring 13's rebound force causes the movable rod 11 to move, thereby moving the baffle 12 to block the through hole 10 and prevent sewage from entering.

[0042] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0043] The device or equipment models mentioned in this article may be as follows:

[0044] Motor 401: Y70S-2.

[0045] Combination Figures 1-5 The specific usage process of the coking wastewater deodorization device of this embodiment is as follows:

[0046] 1. According to the actual use, the sewage is fed into the liquid distribution plate 7 from the inlet 2 and then falls down. The deodorizing agent is fed into the storage tank 9 from the feed pipe 3 and evenly dispersed from the through hole 10. The motor 401 is started to drive the crown gear 403 to rotate from the sleeve 402. This causes the gear 404 to rotate and drive another crown gear 403 to rotate in the opposite direction. Then, the other sleeve 402 drives the stirring blade 408 to rotate in the opposite direction. The stirring blades 408 on the outer circumference of the adjacent sleeves 402 rotate in opposite directions. The sewage after deodorization is discharged from the outlet pipe 6.

[0047] 2: Open the first valve 502 to deliver gas from the gas supply pipe 501 to the distribution pipe 503. The gas is then evenly distributed into the interior of multiple branch pipes 504 through the distribution pipe 503. The gas is then dispersed and escaped in the form of bubbles through the aerator 505.

[0048] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
