Description

Technical Field

[0001] The utility model relates to the technical field of industrial wastewater treatment, in particular to a desulfurization device for industrial wastewater treatment. Background Art

[0002] With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. Industrial wastewater refers to wastewater, sewage and waste liquid generated in the industrial production process, which contains industrial production materials, intermediates and products lost with water, as well as pollutants generated in the production process. Therefore, for protecting the environment, the treatment of industrial wastewater is more important than the treatment of urban sewage. In the process of industrial wastewater desulfurization, it is usually necessary to add industrial wastewater and additives into the reaction tank for stirring, so as to improve the reaction efficiency of industrial wastewater and additives. However, when adding the agent to the equipment, since the desulfurization equipment usually uses a single feeding port, the agent is directly added to the wastewater in the reaction tank at one time, which easily causes the agent to accumulate in a certain area of ​​the wastewater during the addition process. It takes a long time for the stirring device to stir the agent and mix it relatively evenly with the wastewater, which is not conducive to mixing with the wastewater and affects the efficiency of wastewater desulfurization. For this reason, we propose a desulfurization device for industrial wastewater treatment. Utility Model Content

The bottom of the second rotating plate 9 is fixedly connected to a driving block 10. Driven by the second rotating plate 9, the driving block 10 can rotate. An annular storage chamber 11 is provided inside the reaction tank 1. The driving block 10 is in the storage chamber 11. The driving block 10 can rotate at the bottom of the storage chamber 11, and a plurality of unloading mechanisms that can connect the storage chamber 11 with the inside of the reaction tank 1 are connected to the bottom of the storage chamber 11. The driving block 10 can rotate to contact the unloading mechanism, thereby enabling the unloading mechanism to be opened separately, and then the medicine in the storage chamber 11 can be unloaded through different unloading mechanisms, and the quantitative unloading of the medicine can be achieved through the uniform rotation of the second rotating plate 9.

[0024] See also Figures 1 to 2 The outside of the reaction tank 1 is provided with a drug inlet 4 connected to the top of the storage chamber 11. The drug can be added to the storage chamber 11 through the drug inlet 4. The bottom of the storage chamber 11 is arc-shaped, so that the drug in the storage chamber 11 can be automatically concentrated to the middle of the bottom of the storage chamber 11, so that it can be discharged more smoothly. The unloading mechanism is at the bottom of the arc-shaped bottom of the storage chamber 11.

[0025] See also Figures 1 to 5 The unloading mechanism includes a plug 12, a cross bracket 13, and a first spring 14. A conical discharge port is provided at the bottom of the arc-shaped bottom of the storage chamber 11. A matching plug 12 is movably connected to the discharge port. The plug 12 can block the discharge port, and then when one of the plugs 12 is opened, the other plugs 12 can close the discharge port, so that the medicine can be discharged separately.

[0026] See also Figures 1 to 5A cross bracket 13 is fixedly connected to the inside of the bottom end of the discharge port, and the middle of the cross bracket 13 is movably connected to the plug 12. The plug 12 can move relative to the cross bracket 13, and a first spring 14 is fixedly connected to the top of the cross bracket 13. The top of the first spring 14 is fixed to the plug 12. Under the action of the elastic force of the first spring 14, when the driving block 10 is not in contact with the plug 12, the plug 12 can block the discharge port in time.

[0027] See also Figures 1 to 4 A motor 3 is fixedly connected to the center of the top of the reaction tank 1, and the output shaft of the motor 3 is fixed to the center of the top of the first rotating plate 5. Driven by the output shaft of the motor 3, the first rotating plate 5 can rotate, and the motor 3 is connected to a controller, which can make the motor 3 rotate forward and reverse. The controller and the motor 3 are both existing technologies and will not be described here.

[0028] See also Figures 1 to 6 A plurality of first ratchet grooves in the shape of a quarter circle are provided on the inner side of the reaction tank 1, and a plurality of second ratchet grooves in the shape of a quarter circle are provided on the inner side of the second rotating plate 9. The first ratchet grooves and the second ratchet grooves are arranged oppositely, so that when the reaction tank 1 and the second rotating plate 9 rotate relative to each other, the second rotating plate 9 and the first rotating plate 5 remain relatively stationary, and when the first rotating plate 5 and the second rotating plate 9 rotate relative to each other, the reaction tank 1 and the second rotating plate 9 remain relatively stationary.

[0029] See also Figures 1 to 6 The outer side of the second rotating plate 9 is movably connected with a first ratchet 15 that matches the first ratchet groove, one end of the first ratchet 15 is fixedly connected to a second spring 16, and the other end of the second spring 16 is fixedly connected to the second rotating plate 9, and the outer side of the first rotating plate 5 is movably connected with a second ratchet 17 that matches the second ratchet groove, one end of the second ratchet 17 is fixedly connected to a third spring 18, and the other end of the third spring 18 is fixedly connected to the first rotating plate 5.

[0030] See also Figures 1 to 4 A stirring paddle 6 is fixedly connected to the center of the bottom of the first rotating plate 5, and the stirring paddle 6 has two mixing plates with a spiral strip structure. The two mixing plates on the stirring paddle 6 can make the wastewater in the reaction tank 1 run in an axial flow state under a laminar flow state, thereby making the mixing of the reagent and the wastewater more complete.

[0031] In summary, when the desulfurization device for industrial wastewater treatment is used, the first rotating plate 5 is driven by the output shaft of the motor 3 to rotate. First, the first rotating plate 5 drives the second rotating plate 9 to rotate through the second ratchet 17, and then the stirring paddle 6 and the driving block 10 are able to rotate together. The two mixing plates on the stirring paddle 6 can make the wastewater in the reaction tank 1 run in an axial flow state under a laminar flow state, and under the rotation of the driving block 10, the driving block 10 can contact the plugs 12 at different positions in turn, and then push the plug 12 to open, so that the reagent in the storage chamber 11 can be quantitatively and added to the reaction tank 1 at different positions, so that it can be mixed with the wastewater in the reaction tank 1. When the amount of reagent added in the wastewater inside the reaction tank 1 reaches saturation, the controller controls the motor 3 to rotate in the opposite direction, so that the first rotating plate 5 can rotate alone, thereby fully mixing the wastewater and the reagent in the reaction tank 1. When the treated wastewater is opened, the valve 8 is opened and discharged through the liquid outlet 7.
