Description

Technical Field

[0001] The invention relates to the technical field of sulfur-containing wastewater treatment, and in particular to a desulfurization wastewater treatment device. Background Art

[0002] Industrial wastewater includes production wastewater, production wastewater and cooling water. Considering the needs of environmental protection and resource recovery, industrial wastewater cannot be discharged directly. At the same time, industrial wastewater contains a lot of sulfides. During sewage treatment, the sewage needs to be desulfurized before it can be discharged or used in the next step.

[0003] Existing sewage treatment desulfurization often adopts physical and chemical methods such as chemical precipitation and flocculation precipitation. In traditional circular water storage tanks, flocculant particles need to be continuously sprinkled by workers during the desulfurization sewage treatment process. Relying only on simple stirring devices, there will often be a mixing dead zone in the center of the pool or in the area away from the stirring paddle, resulting in the flocculant particles and sewage cannot be fully and evenly mixed; in the desulfurization sewage treatment process, with the effects of sedimentation, a large amount of sludge will settle to the bottom of the pool. If it is not cleaned in time, the sludge will gradually adhere to the bottom of the pool, and then the sludge adheres to the bottom of the pool too much, resulting in anaerobic fermentation.

[0024] A material discharge assembly is provided at the bottom of the rectangular fixed frame 1, and the material discharge assembly includes a storage barrel 16 symmetrically fixedly connected to the inside of the rectangular fixed frame 1, and the upper and lower ends of the storage barrel 16 extend to the outside of the rectangular fixed frame 1 respectively, and a sealing cover is threadedly installed on the top of the storage barrel 16. No less than two storage barrels 16 are provided, which are located on both sides of the stepping motor 2. A discharge hole 17 is opened at the bottom of each storage barrel 16, and a rotating disc 18 is fixedly connected to the outside of the rotating column 4. The top of the rotating disc 18 is in contact with the storage barrel 16, and the bottom of the inner cavity of the storage barrel 16 is set as a slope.

[0025] The unloading component also includes circular holes 19 symmetrically opened on the rotating disc 18, and the circular holes 19 are located at the eccentric part of the rotating disc 18. There are at least two circular holes 19, and the bottom of the rotating disc 18 is symmetrically fixedly connected with a discharge pipe 20. There are at least two discharge pipes 20. The size of the discharge hole 17 is adapted to the size of the circular hole 19, and the discharge hole 17 is located on the movement path of the circular hole 19, and the circular hole 19 is connected to the discharge pipe 20.

[0026] The bottom of the rectangular fixed frame 1 is provided with a throwing assembly, and the throwing assembly includes a rotating hopper 21 rotatably connected to the top of each fixed plate 11, and the rotating hopper 21 extends to the outside of the rotating column 16, and the rotating hopper 21 is provided with no less than two, and the outside of the rotating hopper 21 is fixedly connected with a discharge pipe 22, and the rotating hopper 21 is fixedly connected with a gear 1 23, and the gear 1 23 is located on the upper surface of the fixed plate 11, so as to Fig. 9 As shown, a gear 24 is fixedly connected to the rotating column 2 14 corresponding to the gear 1 23 , the gear 1 23 and the gear 2 24 are meshed with each other, and the number of teeth of the gear 2 24 is twice the number of teeth of the gear 1 23 , and the rotating hopper 21 passes through the interior of the gear 1 23 .

[0027] The above implementation works as follows: The initialization steps are as follows: The staff unscrews the screws on the lids of the two storage barrels 16, and at the same time, the staff calculates the number of flocculant particles required based on the amount of sewage to be treated in the circular water storage tank, and then pours the flocculant particles into the storage barrels 16 respectively, and the discharge hole 17 does not overlap with the circular hole 19.

[0028] The working steps are as follows: The working steps of the stirring assembly are as follows: The staff controls the stepper motor 2 to start. After the stepper motor 2 is energized, it drives the rotating column 4 to rotate on the circular fixed frame 3. Therefore, the bottom of the rotating column 4 drives the cylinder 5 to rotate with its own center as the axis, so that the cylinder 5 drives the two rotating columns 1 6 to make a circular motion with the center of the cylinder 5 as the axis, so that the rotating column 1 6 makes a circular motion on the pool surface of the central water storage tank. At the same time, the rotating column 1 6 also pushes the multiple rotating columns 2 14 to move synchronously in the sewage of the circular water storage tank. Therefore, the multiple rotating columns 2 14 drive the rubber scraper 15 to move synchronously. At this time, the electric telescopic rod 8 is energized to push the fixed rod 9 to move in the direction away from the fixed block 7, and the fixed rod 9 pushes the connecting rod 1 10 to move synchronously. The connecting rod 1 10 pushes the connecting rod 2 12 to move in the direction away from the connecting rod 1 10, and the connecting rod 2 12 drives the connecting rod 3 13 and the rotating column 2 14 as the axis to rotate in the direction away from the connecting rod 10, so as to rotate according to the multiple The movement of connecting rod three 13 causes connecting rod two 12 to be displaced, and connecting rod two 12 now presents counterclockwise curved motion. The function of connecting rod one 10 is to prevent connecting rod two 12 from getting stuck when being displaced. At the same time, connecting rod three 13 drives rotating column two 14 to start rotating at the bottom of fixed plate 11 with the center of the circle at the connection between rotating column two 14 and fixed plate 11 as the axis. Therefore, rotating column two 14 drives rubber scraper 15 to start rotating ninety degrees, so that multiple rotating columns two 14 rotate ninety degrees synchronously and form a closure with each other. At the same time, the staff drives the electric telescopic rod 8 to start contracting. At this time, the above steps can be repeated in reverse, so that rotating column two 14 can realize reciprocating swing, and at the same time, multiple rubber scrapers 15 can also realize synchronous swing, so that the reciprocating swinging rubber scraper 15 can play a stirring role, and at the same time, the reciprocating swinging of the rubber scraper 15 can disturb the sewage in the circular water storage tank.

[0029] The reciprocating swing of the rubber scraper 15 can disturb the sewage in the circular water storage tank. Compared with the traditional static or simple flow mode, the disturbance causes the gas-liquid interface to be continuously updated, the oxygen mass transfer coefficient is significantly improved, and the aeration effect of the sewage is enhanced. The disturbance can prevent the metal ions such as calcium and magnesium in the desulfurized sewage from forming scale and depositing on the surface of the equipment. At the same time, the rubber scraper 15 rotates 90 degrees and fits together to form a whole, which can further increase the purpose of disturbing the sewage, and then the way of stirring the sewage can be adjusted according to the changes between the rubber scrapers 15.

[0030] The working steps of blanking components are as follows: As described above, when the stepper motor 2 is powered on and started, the rotating column 4 drives the rotating disc 18 to rotate on the rotating column 4 with the rotating disc 18's own center as the axis, so that the upper surface of the rotating disc 18 continuously passes through the lower surface of the storage barrel 16. Because the discharge hole 17 is located on the movement path of the circular hole 19, when the rotating disc 18 continuously rotates so that the discharge hole 17 coincides with the circular hole 19, the flocculant particles located inside the storage barrel 16 are no longer restricted by the upper surface of the rotating disc 18, so that the flocculant particles pass through the discharge hole 17 and the circular hole 19 into the discharge pipe 20.

[0031] The setting of the feeding component reduces the number of working steps of continuously throwing flocculant particles during the sewage desulfurization process, reduces the workload of the staff, and avoids the situation where the flocculant particles are not sufficiently contacted with the metal ions in the desulfurized sewage due to one-time throwing. The throwing method can effectively achieve the purpose of uniform delivery to multiple areas, avoiding the problem of uneven mixing caused by manual delivery in a certain area.

[0032] The working steps of the throwing component are as follows: The flocculant particles then fall from the discharge pipe 20 to the rotating hopper 21 by their own gravity. At the same time, as mentioned above, the electric telescopic rod 8 is constantly extending and contracting, so that the reciprocating motion of the rotating column 21 drives the gear 24 to rotate clockwise and counterclockwise. Since the number of gear blocks of the gear 24 is twice the number of gear blocks of the gear 1 23, the rotation amplitude of the gear 24 is smaller than the rotation amplitude of the gear 1 23. Therefore, the gear 24 drives the gear 1 23 to rotate clockwise and counterclockwise, and the gear 1 23 drives the rotating hopper 21. The hopper 21 reciprocates with the center of the connection between the rotating hopper 21 and the fixed plate 11 as the axis, and the rotating hopper 21 drives the discharge pipe 22 to swing back and forth clockwise and counterclockwise continuously. Since the flocculant particles on the rotating hopper 21 have their own weight, the flocculant particles have inertia, so the discharge pipe 22 swings continuously to scatter the flocculant particles. At the same time, the rotating column 1 6 continuously performs a circular motion with the center of the cylinder 5 as the axis, so the flocculant particles can perform a circular motion in the circular water storage tank and be scattered.

[0033] The setting of the spreading component can make the flocculant particles move in a circular motion and be spread in the circular water storage tank. They will move along the circular trajectory, covering the edge and the middle area of ​​the water tank, increasing the contact area with the sewage, avoiding the situation where the flocculant particles and sewage cannot be fully and evenly mixed, resulting in improper sewage treatment, and further increasing the uniformity of the spreading of flocculant particles in the sewage tank.

[0034] When the flocculant particles required for the sewage in the circular water storage tank are put in, the electric telescopic rod 8 no longer contracts. At this time, the electric telescopic rod 8 is extended and remains stationary, so the rotating column 14 drives the rubber scraper 15 to start rotating ninety degrees, so that the multiple rotating columns 14 rotate ninety degrees synchronously to form a closed state. At this time, the multiple rubber scrapers 15 form a complete plate shape, and because the bottom of the rubber scraper 15 is in contact with the bottom of the circular water storage tank, the flocculant particles in the sewage, some fine calcium sulfite, calcium sulfate particles and organic particles in the sewage, etc., form flocs under the action of the flocculant, and can quickly settle to the bottom in the sedimentation tank or clarification tank. At this time, the multiple rubber scrapers 15 form a complete board to continuously scrape the bottom of the circular water storage tank to avoid the flocs from being retained on the bottom of the circular water storage tank for a long time and causing adhesion.

[0035] The rotating and closing arrangement of multiple rubber scrapers 15 can continuously scrape the bottom of the circular water storage tank, and can clean up newly settled sludge and flocs in real time, ensuring that the bottom of the circular water storage tank always remains relatively clean, while avoiding anaerobic fermentation caused by excessive sludge adhering to the tank.
