[0003] As a highly efficient inorganic material, reducing agent has excellent photocatalytic, adsorption and antibacterial properties, and has received extensive attention in the field of sewage treatment in recent years. Reducing agent can degrade organic pollutants through photocatalysis, adsorb heavy metal ions, and inhibit bacterial growth, thereby significantly improving the sewage treatment effect. However, when preparing the reducing agent, the sewage generated by it needs to be treated.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 4 As shown, an active zinc oxide preparation sewage treatment device according to an embodiment of the present invention comprises a sewage treatment pipeline 1, a drug delivery pipeline 2 is installed above the sewage treatment pipeline 1, a reducing agent is stored inside the drug delivery pipeline 2, a sedimentation tank 3 is installed on the side of the sewage treatment pipeline 1, a plurality of rotating columns 101 are rotatably connected inside the sewage treatment pipeline 1, and the plurality of rotating columns 101 are arranged at intervals, a drug delivery pipe 4 is installed on the lower end surface of the drug delivery pipeline 2, and the drug delivery pipe 4 is used to intermittently feed the reducing agent, and a cleaning mechanism is provided on the outer peripheral surface of the rotating column 101, and the cleaning mechanism is used to remove ferromagnetic impurities in sewage; During operation, the sewage treatment pipeline 1 is connected to the external treatment tank through a connecting pipeline, and the sewage is passed into the sewage treatment pipeline 1. At the same time, the prepared reducing agent is passed into the sewage treatment pipeline 1 through the drug delivery pipeline 2. The reducing agent has the functions of adsorption, catalytic oxidation, etc. in sewage treatment, and can effectively remove pollutants such as heavy metals and organic matter. Moreover, the reducing agent can be intermittently delivered under the action of the drug delivery pipe 4, which not only does not waste the raw materials of the reducing agent, but also is beneficial to the treatment of sewage; The treated sewage will then be passed into the sedimentation tank 3 to facilitate the subsequent remaining operations.

[0024] It should be noted that the drug delivery pipeline 2 is externally connected to a pipeline for preparing the reducing agent, and the method for preparing the reducing agent is a prior art in the embodiment of the present invention, and will not be described in detail.

[0025] The cleaning mechanism includes a deflection rod 5 rotatably arranged on the outer circumference of the rotating column 101, wherein a plurality of deflection rods 5 are arranged and are arranged in a circular array on the outer circumference of the rotating column 101, and a plurality of electromagnetic adsorption rods 6 are arranged on the surface of the deflection rod 5, wherein the electromagnetic adsorption rods 6 are used to adsorb iron impurities in the sewage; During the preparation of active zinc oxide, some metal impurities such as iron, copper, and lead will be mixed in the raw materials, which will slowly form preparation waste and be discharged together with the sewage. Figure 2 As shown, the rotating column 101 is designed to be spaced inside the sewage treatment pipe 1, and multiple deflection rods 5 and electromagnetic adsorption rods 6 are provided, and the sewage will pass through these deflection rods 5 and electromagnetic adsorption rods 6 when flowing. Therefore, under the action of the electromagnetic adsorption rods 6, the iron impurities in the sewage can be adsorbed, which is convenient for the subsequent sedimentation tank 3 to continue to treat the sewage, thereby improving the sewage treatment effect.

[0026] like Figures 2 to 5As shown, the outer circumference of the rotating column 101 is fixedly connected with a plurality of propeller blades 7, and the plurality of propeller blades 7 are designed in a circular array on the outer circumference of the rotating column 101, and a rotation speed sensor 8 is installed on the lower end surface of the rotating column 101; during operation, since the rotating column 101 is designed to rotate inside the sewage treatment pipe 1, and the propeller blades 7 are designed on the outer circumference of the rotating column 101, the rotating column 101 will rotate at a certain speed under the impact of sewage, and the rotating column 101 will drive the deflection rod 5 and the electromagnetic adsorption rod 6 to rotate synchronously, so the electromagnetic adsorption rods 6 at different positions will hook the larger impurities inside the sewage treatment pipe 1, thereby improving the treatment effect of larger impurities; It should be noted that a speed sensor 8 is designed on the lower end surface of the rotating column 101. The speed sensor 8 will monitor the rotation speed of the rotating column 101 in real time. If the rotating column 101 does not rotate, the speed sensor 8 will generate a signal and transmit it to the external controller, and the rotation of the rotating column 101 can be controlled by the external controller.

[0027] Each of the deflection rods 5 is provided with a rectangular groove 9, and a rectangular adsorption plate 10 is slidably arranged inside the rectangular groove 9. The shape of the rectangular adsorption plate 10 is adapted to the shape of the rectangular groove 9. A plurality of electromagnetic adsorption rods 6 are designed to rotate in an array on the outer surface of the rectangular adsorption plate 10. When working, refer to the attached drawing. Figure 4 As shown, multiple electromagnetic adsorption rods 6 are provided, so that it is convenient to adsorb metal impurities existing in various aspects in sewage. A rectangular groove 9 is opened inside the deflection rod 5. When the sewage is treated once, the electromagnetic adsorption rod 6 is first controlled to be powered off, and then the iron impurities adsorbed on its surface will fall to the inner wall of the sewage treatment pipe 1. Then, the rectangular adsorption plate 10 can slide into the interior of the rectangular groove 9, and can drive the electromagnetic adsorption rod 6 to slide into the interior of the rectangular groove 9. When the groove wall of the rectangular groove 9 contacts the outer wall of the electromagnetic adsorption rod 6, the rectangular groove 9 has a certain limiting effect, which can push out other impurities that have not fallen on the outer wall of the electromagnetic adsorption rod 6 and drop them into the sewage treatment pipe 1, thereby realizing the automatic recovery function of all impurities.

[0028] like Figures 3 to 7As shown, the inner wall of each rectangular groove 9 is fixedly installed with an electric telescopic column 11, and the telescopic end of the electric telescopic column 11 is connected to the side wall of the rectangular adsorption plate 10. The outer peripheral surface of the rectangular adsorption plate 10 is provided with a plurality of square grooves 12, and the inner wall of each square groove 12 is fixedly connected with a horizontal axis 13, and each electromagnetic adsorption rod 6 is rotatably arranged on the outer peripheral surface of each horizontal axis 13; when working, after the sewage is treated once, when it is necessary to process the iron impurities adsorbed on the outer wall of the electromagnetic adsorption rod 6, the electromagnetic adsorption rod 6 is first controlled to be powered off, and the external controller controls the electric The telescopic end of the movable telescopic column 11 drives the rectangular adsorption plate 10 to move into the rectangular groove 9. During the movement of the rectangular adsorption plate 10 into the rectangular groove 9, the outer wall of the rectangular adsorption plate 10 will contact the inner wall of the rectangular groove 9. Under the limit of the two, the rectangular groove 9 will scrape off the impurities on the outer wall of the rectangular adsorption plate 10, and because the electromagnetic adsorption rod 6 is rotatably arranged on the outer peripheral surface of the horizontal axis 13, when the electromagnetic adsorption rod 6 moves to the inner wall of the rectangular groove 9, the inner wall of the rectangular groove 9 will simultaneously scrape off the remaining impurities on the outer wall of the electromagnetic adsorption rod 6 that have not fallen off, that is, the electromagnetic adsorption rod 6 is removed from the attached Figure 5 and Figure 6 Change to Figure 7 The position shown in the figure makes it convenient for the subsequent centralized treatment of all impurities and improves the sewage treatment effect.

[0029] The inner wall of the square groove 12 is provided with a scraper 121, and the side of the scraper 121 away from the square groove 12 contacts the side wall of the electromagnetic adsorption rod 6. The scraper 121 is rotatably arranged on the inner wall of the square groove 12 through a rotating column. A torsion spring 14 is arranged at the rotation connection between the scraper 121 and the square groove 12. A recovery plate is provided at the bottom of the sewage treatment pipe 1. When working, the electromagnetic adsorption rod 6 is moved from the surrounding Figure 5 and Figure 6 Change to Figure 7 In the position shown, since the electromagnetic adsorption rod 6 is rotatably set on the inner wall of the square groove 12, and when the electromagnetic adsorption rod 6 contacts the inner wall of the rectangular groove 9, the other end face of the electromagnetic adsorption rod 6 contacts the side wall of the scraper 121, the electromagnetic adsorption rod 6 will gradually rotate to the inside of the square groove 12. When it rotates to the inside of the square groove 12, the scraper 121 will continue to scrape the other end face of the electromagnetic adsorption rod 6. Therefore, under the interaction of the rectangular groove 9 and the scraper 121, the remaining impurities on the surface of the electromagnetic adsorption rod 6 can be removed. A recovery plate is set at the bottom of the sewage treatment pipe 1, and metal impurities and other impurities will fall on the top of the recovery plate. The staff can later open the recovery plate to centrally process these fallen impurities.

[0030] It should be noted that the wastewater generated during the preparation of active zinc oxide usually contains zinc ions and other heavy metal ions. These pollutants need to be reduced by a reducing agent. In the embodiment of the present invention, the reducing agent can be sodium sulfide or sodium hydrosulfide.

[0031] like Figures 3 to 10 As shown, a vertical shaft 15 is fixedly mounted on the upper end surface of each rotating column 101, and an intermittent gear 151 is fixedly mounted on the outer peripheral surface of the top end of the vertical shaft 15. A rotating shaft 16 is rotatably arranged on the upper end surface of the sewage treatment pipe 1, and a driven gear 17 is fixedly mounted on the upper end surface of the rotating shaft 16, and the intermittent gear 151 and the driven gear 17 are meshingly connected; during operation, when the rotating column 101 rotates, the rotating column 101 will simultaneously drive the vertical shaft 15 on its upper end surface to rotate, the vertical shaft 15 drives the intermittent gear 151 to rotate, the intermittent gear 151 will drive the driven gear 17 meshingly connected thereto to rotate, the driven gear 17 will drive the rotating shaft 16 to rotate, and the rotating shaft 16 and the driven gear 17 will intermittently feed the reducing agent inside the drug delivery tube 4 into the sewage treatment pipe 1.

[0032] A medicine storage plate 18 is slidably disposed inside the medicine delivery tube 4, a pressure block 19 is installed on the side wall of the medicine storage plate 18, a cam 20 is fixedly installed on the outer peripheral surface of the rotating shaft 16, and when the rotating shaft 16 drives the cam 20 to rotate, the raised end of the cam 20 will contact the arc of the pressure block 19, and a plurality of material distribution grooves 21 are opened on the surface of the medicine storage plate 18; It should be noted that when the drug delivery pipeline 2 is transporting the reducing agent, the reducing agent will fall onto the drug storage plate 18 inside the drug delivery pipe 4. Furthermore, when the drug delivery pipe 4 is in the specific drug delivery process, that is, when the driven gear 17 drives the rotating shaft 16 to rotate, the rotating shaft 16 will simultaneously drive the cam 20 to rotate. The cam 20 will contact the arc portion of the pressure block 19 during the rotation process, so that the pressure block 19 drives the drug storage plate 18 to move, and the drug storage plate 18 will vibrate to a certain extent, so that the reducing agent will fall into the sewage treatment pipe 1 through the dividing groove 21 on the surface of the drug storage plate 18, thereby realizing the function of automatically adding the reducing agent. In addition, the intermittent design of the intermittent gear 151 and the driven gear 17 can intermittently add the reducing agent to avoid the problem of adding too much material at one time and wasting raw materials.

[0033] like Figures 6 to 10As shown, the side wall of the medicine storage plate 18 away from the pressure block 19 is fixedly installed with an elastic telescopic column 22, and the outer peripheral surface of the elastic telescopic column 22 is sleeved with a telescopic spring. The inner wall of the medicine delivery tube 4 and below the medicine storage plate 18 is installed with a medicine dividing plate 23, and the surface of the medicine dividing plate 23 is provided with a plurality of material dividing grooves 231, and the shape of the medicine dividing plate 23 and the medicine storage plate 18 are adapted; when working, in the initial state, the material dividing groove 1 21 on the surface of the medicine storage plate 18 and the material dividing groove 2 231 on the surface of the medicine dividing plate 23 are as shown in the attached figure. Fig. 9 The position shown in the figure, that is, the second material distribution groove 231 and the first material distribution groove 21 are not aligned. When the medicine storage plate 18 moves, the first material distribution groove 21 and the second material distribution groove 231 will move from the initial state to the adjacent Fig.10 As shown in the position, the second dividing trough 231 and the first dividing trough 21 will slowly align, so that the reducing agent will fall from the aligned second dividing trough 231 and the first dividing trough 21 to the interior of the sewage treatment pipe 1. This not only enables intermittent feeding, but also further grinds the reducing agent under the mutual squeezing and grinding of the medicine dividing plate 23 and the medicine storage plate 18, ensuring that the reducing agent in the powder state can combine with the sewage to the greatest extent, thereby improving the sewage treatment effect.

The reducing agent has the functions of adsorption, catalytic oxidation, etc. in sewage treatment, and can effectively remove pollutants such as heavy metals and organic matter; S3. The reducing agent can be transported intermittently under the action of the drug delivery pipe 4.

[0035] During operation, the sewage treatment pipeline 1 is connected to the external treatment tank through a connecting pipeline, and the sewage is passed into the sewage treatment pipeline 1. At the same time, the prepared reducing agent is passed into the sewage treatment pipeline 1 through the drug delivery pipeline 2. The reducing agent has the functions of adsorption, catalytic oxidation, etc. in sewage treatment, and can effectively remove pollutants such as heavy metals and organic matter, and the reducing agent can be intermittently delivered under the action of the drug delivery pipe 4; When preparing activated zinc oxide, its raw materials will be mixed with some metal impurities such as iron, copper, lead, etc., which will slowly form preparation waste and be discharged together with sewage. Figure 2As shown, the rotating column 101 is designed to be spaced inside the sewage treatment pipe 1, and the deflection rod 5 and the electromagnetic adsorption rod 6 are both provided in plurality, and the sewage will pass through these deflection rods 5 and the electromagnetic adsorption rod 6 when circulating, so under the action of the electromagnetic adsorption rod 6, the iron impurities in the sewage can be adsorbed, which is convenient for the subsequent sedimentation tank 3 to continue to treat the sewage, thereby improving the sewage treatment effect; when the sewage is treated once, the electromagnetic adsorption rod 6 is first controlled to be powered off, and then the iron impurities adsorbed on its surface will fall to the inner wall of the sewage treatment pipe 1. The rectangular adsorption plate 10 can slide into the interior of the rectangular groove 9, and can drive the electromagnetic adsorption rod 6 to slide into the interior of the rectangular groove 9. When the groove wall of the rectangular groove 9 contacts the outer wall of the electromagnetic adsorption rod 6, the rectangular groove 9 has a certain limiting effect, which can push out other impurities that have not fallen on the outer wall of the electromagnetic adsorption rod 6 and drop them into the sewage treatment pipe 1, thereby realizing the automatic recovery function of all impurities; After the sewage is treated once, when it is necessary to treat the ferrous impurities adsorbed on the outer wall of the electromagnetic adsorption rod 6, the external controller controls the telescopic end of the electric telescopic column 11 to drive the rectangular adsorption plate 10 to move toward the inside of the rectangular groove 9. During the movement of the rectangular adsorption plate 10 toward the inside of the rectangular groove 9, the outer wall of the rectangular adsorption plate 10 will contact the inner wall of the rectangular groove 9. Under the limit of both, the rectangular groove 9 will scrape off the impurities on the outer wall of the rectangular adsorption plate 10, and since the electromagnetic adsorption rod 6 is rotatably arranged on the outer peripheral surface of the horizontal axis 13, when the electromagnetic adsorption rod 6 moves to the inner wall of the rectangular groove 9, the inner wall of the rectangular groove 9 will simultaneously scrape off the remaining impurities on the outer wall of the electromagnetic adsorption rod 6 that have not fallen off, that is, the electromagnetic adsorption rod 6 is removed from the attached Figure 5 and Figure 6 Change to Figure 7 The position shown in the figure makes it convenient for the subsequent centralized treatment of all impurities and improves the sewage treatment effect; The electromagnetic adsorption rod 6 is attached Figure 5 and Figure 6 Change to Figure 7 When in the position shown, since the electromagnetic adsorption rod 6 is rotatably arranged on the inner wall of the square groove 12, and when the electromagnetic adsorption rod 6 contacts the inner wall of the rectangular groove 9, the other end face of the electromagnetic adsorption rod 6 contacts the side wall of the scraper 121, the electromagnetic adsorption rod 6 will gradually rotate to the inside of the square groove 12. When it rotates to the inside of the square groove 12, the scraper 121 will continue to scrape the other end face of the electromagnetic adsorption rod 6. Therefore, under the interaction of the rectangular groove 9 and the scraper 121, the remaining impurities on the surface of the electromagnetic adsorption rod 6 can be removed. A recovery plate is set below the sewage treatment pipe 1, and the metal impurities and other impurities will fall on the recovery plate. The staff can open the recovery plate later to centrally process these fallen impurities. When the rotating column 101 rotates, the rotating column 101 will simultaneously drive the vertical shaft 15 on its upper end surface to rotate, the vertical shaft 15 drives the intermittent gear 151 to rotate, the intermittent gear 151 will drive the driven gear 17 meshing with it to rotate, the driven gear 17 will drive the rotating shaft 16 to rotate, the rotating shaft 16 and the driven gear 17 will intermittently feed the reducing agent inside the medicine delivery tube 4 into the sewage treatment pipeline 1; when the medicine delivery tube 4 is in the specific medicine delivery process, that is, when the driven gear 17 drives the rotating shaft 16 to rotate, the rotating shaft 16 will The cam 20 is driven to rotate, and the cam 20 will contact the arc of the pressure block 19 during the rotation process, so that the pressure block 19 drives the medicine storage plate 18 to move, and the medicine storage plate 18 will vibrate to a certain extent, so that the reducing agent will fall into the sewage treatment pipeline 1 through the material distribution groove 21 on the surface of the medicine storage plate 18, realizing the function of automatically feeding the reducing agent. In addition, the intermittent design of the intermittent gear 151 and the driven gear 17 is designed, which can intermittently feed the reducing agent, avoiding the problem of feeding too much at one time and wasting raw materials; In the initial state, the material distribution groove 1 21 on the surface of the medicine storage plate 18 and the material distribution groove 2 231 on the surface of the medicine distribution plate 23 are as shown in the attached figure.
