Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sulfur-containing sewage treatment, in particular to a desulfurization sewage treatment device. BACKGROUND

[0002] Industrial wastewater includes production wastewater, production sewage and cooling water. Considering the needs of environmental protection and resource recycling, industrial wastewater cannot be directly discharged. At the same time, there are more sulfides in industrial wastewater. The wastewater needs to be desulfurized before being discharged or used in the next step.

[0003] The existing desulfurization sewage treatment often uses chemical precipitation method, flocculation precipitation method and other physical and chemical methods for treatment. In the traditional circular water tank, the flocculant particles need to be continuously scattered by the staff during the desulfurization sewage treatment process. Only relying on a simple stirring device, a mixing dead zone often appears in the center area of the tank or the area far away from the stirring paddle, which causes the flocculant particles and the sewage to not be fully and uniformly mixed. During the desulfurization sewage treatment process, a large amount of sludge will be precipitated to the bottom of the tank due to precipitation and other effects. If not cleaned in time, the sludge will gradually adhere to the bottom of the tank, and then the anaerobic fermentation caused by too much sludge adhering to the bottom of the tank will occur.

[0004] Therefore, a desulfurization sewage treatment device is proposed. SUMMARY

[0008] Further, the discharging assembly further comprises circular holes symmetrically arranged on the rotating disc, the circular holes are not less than two, the bottom of the rotating disc is fixedly connected with a discharging pipe one, and the discharging pipe one is not less than two.

[0009] Further, the bottom of the rectangular fixed frame is provided with a discharging assembly, the discharging assembly comprises symmetrical storage barrels fixedly connected to the inside of the rectangular fixed frame, the storage barrels are not less than two, the bottom of each storage barrel is provided with a discharging hole, and the outside of the rotating column is fixedly connected with a rotating disc.

[0010] Further, the outside of the rotating column is rotatably connected with the circular fixed frame.

[0011] Further, the top of the rotating column is rotatably connected with the lower surface of the fixed plate, and the rotating column passes through the outside of the rotating column one.

[0012] Further, the top of the rotating disc is matched with the storage barrel, and the bottom of the inner cavity of the storage barrel is provided as an inclined slope.

[0014] Further, the gear one is engaged with the gear two, the number of the gear blocks of the gear two is twice the number of the gear blocks of the gear one, and the rotating hopper passes through the inside of the gear one.

[0015] Compared with the prior art, the beneficial effects of the present application are:

[0016] The reciprocating swing of the rubber scraper can disturb the flow of the circular water storage pool, so that compared with the traditional static or simple flow mode, the disturbance continuously updates the gas-liquid interface, significantly improves the mass transfer coefficient of oxygen, enhances the aeration effect of the sewage, and prevents the deposition of scale containing calcium, magnesium and other metal ions in the desulfurization sewage on the surface of the equipment. At the same time, the rubber scrapers are rotated by ninety degrees and matched with each other to form a whole, which can further increase the purpose of disturbing the sewage, and then the stirring mode of the sewage can be adjusted according to the change between the rubber scrapers.

[0017] The setting of the discharging assembly reduces the work steps of the staff in the process of sewage desulfurization, reduces the work load of the staff, and avoids the insufficient contact of the flocculant particles with the metal ions in the desulfurization sewage caused by one-time scattering of the flocculant particles. The scattering mode can effectively achieve the purpose of uniform distribution in multiple areas, and avoids the problem of uneven mixing caused by manual distribution in a certain area.

[0018] The setting of the scattering assembly enables the flocculant particles to move in a circular motion in the circular water tank and be scattered. They move along the circular track, cover the edge and the middle area of the water tank, and increase the contact area with the sewage, avoiding the improper sewage treatment caused by insufficient and uniform mixing of the flocculant particles and the sewage, and further increasing the uniformity of the scattered flocculant particles in the sewage tank.

[0019] The setting of the multiple rubber scrapers rotating and closing enables the bottom of the circular water tank to be scraped continuously, the newly precipitated sludge and floc to be cleaned in real time, and the bottom of the circular water tank to be kept in a relatively clean state, while avoiding the anaerobic fermentation caused by excessive adhesion of sludge to the tank.

[0042] The working principle of the above embodiment is as follows:

[0043] The initialization steps are as follows:

[0044] The worker unscrews the screws on the cover of the two storage barrels 16, and calculates the number of flocculant particles according to the amount of sewage to be treated in the circular water storage pool, so that the worker pours the flocculant particles into the storage barrel 16, and the discharge hole 17 and the circular hole 19 are not coincident.

[0045] The working steps are as follows:

[0046] The working steps of the stirring assembly are as follows:

[0047] The staff controls the starting of the step motor 2, and the step motor 2 drives the rotating column 4 to rotate on the circular fixed frame 3 after being electrified, so that the bottom of the rotating column 4 drives the cylinder 5 to rotate with the center of the cylinder 5 as the axis, so that the cylinder 5 drives the two rotating columns I 6 to move in a circle with the center of the cylinder 5 as the axis, so that the rotating column I 6 moves in a circle on the surface of the circular water pool, and the rotating column I 6 also pushes the plurality of rotating columns II 14 to move synchronously in the sewage in the circular water pool, so that the plurality of rotating columns II 14 drive the rubber scrapers 15 to move synchronously, at this time, the electric telescopic rod 8 is electrified to drive the fixed rod 9 to move away from the fixed block 7, the fixed rod 9 drives the connecting rod I 10 to move synchronously, the connecting rod I 10 drives the connecting rod II 12 to move away from the connecting rod I 10, the connecting rod II 12 drives the connecting rod III 13 and the rotating column II 14 to rotate away from the connecting rod I 10, so that the displacement of the connecting rod II 12 is caused according to the movement of the plurality of connecting rod III 13, the connecting rod II 12 presents counterclockwise curve movement at this time, and the connecting rod I 10 avoids the situation that the connecting rod II 12 is stuck when being displaced, and the connecting rod III 13 drives the rotating column II 14 to rotate on the bottom of the fixed plate 11 with the center of the connection between the rotating column II 14 and the fixed plate 11 as the axis, so that the rotating column II 14 drives the rubber scraper 15 to rotate by ninety degrees, so that the plurality of rotating columns II 14 synchronously rotate by ninety degrees to form a closure between each other, and at this time, the staff drives the electric telescopic rod 8 to start to contract, and the above-mentioned reverse steps can be repeated, so that the rotating column II 14 can realize reciprocating swing, and the plurality of rubber scrapers 15 can realize synchronous swing, so that the rubber scraper 15 which can realize reciprocating swing plays a stirring role, and the reciprocating swing of the rubber scraper 15 can disturb the flow of the sewage in the circular water pool.

[0048] The reciprocating swing of the rubber scraper 15 plays a role of disturbing the flow of the sewage in the circular water pool, so that compared with the traditional static or simple flow mode, the disturbance continuously updates the gas-liquid interface, significantly improves the mass transfer coefficient of oxygen, enhances the aeration effect of the sewage, and prevents the deposition of scale formed by calcium, magnesium and other metal ions in the desulfurization sewage on the surface of the equipment, and at the same time, the rubber scraper 15 rotates by ninety degrees to form a whole with each other, which can further disturb the flow of the sewage, and the stirring mode of the sewage can be adjusted according to the change between the rubber scrapers 15.

[0049] The working steps of the blanking assembly are as follows:

[0050] As described above, when the stepper motor 2 is powered on, at this time the rotating column 4 drives the rotating disc 18 to rotate on the rotating column 4 with the center of the rotating disc 18 as the axis, so that the upper surface of the rotating disc 18 continuously passes through the lower surface of the storage barrel 16, and because the discharge hole 17 is located on the movement path of the circular hole 19, when the rotating disc 18 continuously rotates to make the discharge hole 17 coincide with the circular hole 19, at this time 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 enter the discharge pipeline one 20 through the discharge hole 17 and the circular hole 19.

[0051] The setting of the discharging assembly reduces the work steps of the staff continuously pouring flocculant particles in the process of sewage desulfurization, reduces the work load of the staff, and avoids the situation that the one-time pouring of flocculant particles causes insufficient contact with metal ions in the desulfurization sewage. Through the pouring mode, the purpose of uniform distribution in multiple areas can be achieved, and the problem of uneven mixing caused by manual distribution in a certain area can be avoided.

[0052] The working steps of the pouring assembly are as follows:

[0053] The flocculant particles fall from the discharge pipeline one 20 to the rotating hopper 21 by their own gravity, and as described above, the electric telescopic rod 8 continuously performs the extension and contraction movement, so that the reciprocating movement of the rotating column two 14 drives the gear two 24 to rotate clockwise and counterclockwise, and because the number of gear blocks of the gear two 24 is twice the number of gear blocks of the gear one 23, the rotation amplitude of the gear two 24 is less than the rotation amplitude of the gear one 23, so that the gear two 24 drives the gear one 23 to also rotate clockwise and counterclockwise, and the gear one 23 drives the rotating hopper 21 to rotate reciprocally with the center of the connection between the rotating hopper 21 and the fixed plate 11 as the axis, so that the rotating hopper 21 drives the discharge pipeline two 22 to continuously reciprocate clockwise and counterclockwise, so that the flocculant particles on the rotating hopper 21 have inertia due to their own weight, and the discharge pipeline two 22 continuously swings to pour the flocculant particles, and the rotating column one 6 continuously performs the circumferential movement with the center of the cylinder 5 as the axis, so that the flocculant particles can perform circumferential movement and pouring in the circular water pool.

[0054] The setting of the pouring assembly enables the flocculant particles to perform circumferential movement and pouring in the circular water pool, which moves along the circumferential track, covers the edge and the middle area of the pool, and increases the contact area with the sewage, avoiding the situation that the flocculant particles and the sewage cannot be mixed uniformly, causing improper sewage treatment, and further increasing the uniformity of the flocculant particles poured in the sewage pool.

[0055] When the required flocculant particles in the sewage in the circular water tank are put in, the electric telescopic rod 8 no longer retracts at this time, the electric telescopic rod 8 extends and remains stationary at this time, so the rotating column two 14 drives the rubber scraper 15 to start rotating ninety degrees, so that multiple rotating column two 14 synchronously rotate ninety degrees to form a closure, at this time multiple rubber scrapers 15 form a complete board shape, and because the bottom of the rubber scraper 15 and the bottom of the circular water tank are mutually attached, so that the flocculant particles in the sewage, some small calcium sulfite, calcium sulfate particles and organic matter particles in the sewage, under the action of the flocculant, form flocs, which can quickly settle to the bottom in the sedimentation tank or clarifier at this time. Multiple rubber scrapers 15 form a complete board that continuously scrapes the bottom of the circular water tank to avoid the situation of adhesion caused by long-term retention of flocs on the bottom of the circular water tank.

[0056] The rotating and closing of multiple rubber scrapers 15 can continuously scrape the bottom of the circular water tank, and can clean the newly settled sludge and flocs in real time, ensuring that the bottom of the circular water tank is always kept relatively clean, while avoiding the situation of anaerobic fermentation caused by too much sludge adhesion.
