Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically an industrial waste acid recovery and impurity removal device. Background Technology
[0002] With energy shortages, resource scarcity, and severe environmental pollution, environmental protection has become a global issue, attracting the attention of the entire society and all of humanity. A large amount of acidic waste liquid is generated during industrial production, which contains many metallic impurities, as well as metal ions and useful acids of varying concentrations. Direct discharge of such waste liquid not only wastes resources and pollutes the environment but also poses a threat to human health.
[0003] In the prior art, an industrial waste acid recovery and impurity removal device with authorization announcement number CN221733272U includes a vessel body for holding waste acid. The top of the vessel body is detachably connected to a vessel cover. The top surface of the vessel cover is fixedly connected to and connected to a material dispersing component for uniformly dispersing the raw materials for neutralizing the waste acid. Several water outlet holes are opened on the side of the vessel body. A receiving plate is fixedly installed on the side of the vessel body. The receiving plate is fixedly connected to and connected to a connecting component. The connecting component is connected to the inner cavity of the vessel body. A liquid pushing component is slidably connected to the bottom surface of the inner cavity of the vessel body. A first one-way valve is fixedly connected to and connected to the bottom end of the side of the vessel body. The receiving plate and the outer surface of the vessel body form a receiving cavity, which is connected to the inner cavity of the vessel body through the water outlet holes.
[0004] The device uses a pusher plate to push waste acid upwards, thus delivering it to the top of the filter cotton for filtration. During use, the raw materials for removing impurities fall onto the waste acid and react with it. Only after the reaction is complete does the pusher plate push the waste acid for filtration. During the reaction, because the waste acid inside the reactor does not flow, the raw materials cannot be mixed evenly with the waste acid, affecting the waste acid treatment efficiency. Furthermore, when the raw materials fall onto the surface of the waste acid and react, the pH difference between the upper and lower parts of the waste acid can become too large, causing the precipitated impurities to redissolve in the acidic area at the bottom, thus affecting the device's impurity removal efficiency. Utility Model Content

[0012] Preferably, the mounting plate is slidably connected to the inside of two placement slots. The mounting plate has an installation slot inside, and a filter element is installed inside the installation slot. Workers can pull the mounting plate out of the placement slot, which makes it convenient for workers to replace the filter element.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. In this application, the stirring rod and the second stirring blade disperse the raw materials when they rotate, so that they are evenly distributed on the top of the material distribution cone. The rotating shaft drives the material distribution cone to rotate at the same time. The material distribution cone causes the raw materials to be evenly thrown onto the wastewater surface along the inclined surface of the material distribution cone, thereby improving the uniformity of the material distribution. At the same time, the first stirring impeller stirs the waste acid to prevent the local concentration of raw materials in the waste acid from being too high, which would affect the impurity removal efficiency of the device.
[0015] 2. In this application, the baffle plate collides with the water flow that follows the rotation of the first stirring impeller, thereby improving the mixing and reaction efficiency of the raw materials and waste acid. At the same time, the screw rod collects the precipitated impurities through the collection port at the bottom of the baffle plate, thereby removing impurities from inside the waste acid.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example: Figure 1 - Figure 5As shown, this utility model provides a technical solution for an industrial waste acid recovery and impurity removal device, including a tank body 1. A rotating shaft 4 is rotatably connected inside the tank body 1. Two first stirring impellers 6 are fixedly connected to the outer side of the bottom end of the rotating shaft 4. A feed cylinder 8 is rotatably installed on the top of the tank body 1. A material distribution cone wheel 10 adapted to the feed cylinder 8 is fixedly connected to the outer side of the rotating shaft 4. Three baffles 16 are fixedly connected in a circumferential array on the inner wall of the tank body 1. A spiral rod 17 is rotatably installed inside each of the three baffles 16. A placement box 19 is fixedly connected to one side of each of the three baffles 16. An installation plate 20 is provided on one side of each of the three placement boxes 19.
[0024] Two second stirring blades 7 are fixedly connected to the outer side of the top of the rotating shaft 4. Multiple stirring rods 9 are fixedly connected inside the feed cylinder 8. The multiple stirring rods 9 are staggered with the two second stirring blades 7. A third gear 11 is fixedly connected to the top of the outer side of the feed cylinder 8. During operation, the rotating shaft 4 and the feed cylinder 8 rotate in opposite directions, so that the second stirring blades 7 and stirring rods 9 strike the raw material entering the feed cylinder 8, so that the raw material is evenly scattered on the top of the material distribution cone wheel 10. The material distribution cone wheel 10 rotates and evenly throws the raw material into the inside of the tank 1.
[0025] A second gear 5 is fixedly connected to the top of the rotating shaft 4, a motor 2 is fixedly installed on the top of the tank body 1, a first gear 3 is fixedly connected to the output end of the motor 2, the first gear 3 meshes with the second gear 5, and a feed port adapted to the feed cylinder 8 is opened on the top of the tank body 1.
[0026] A connecting shaft 12 is rotatably connected to the top of the tank body 1. Both ends of the connecting shaft 12 are fixedly connected to transmission gears 13. The two transmission gears 13 are respectively meshed with the first gear 3 and the third gear 11. Multiple connecting rods 14 are fixedly connected to the bottom of the third gear 11. A toothed ring 15 is fixedly connected to the top of one end of the multiple connecting rods 14.
[0027] The tops of the three spiral rods 17 are rotatably connected to the tank body 1, and the outer sides of the tops of the three spiral rods 17 are fixedly connected to the fourth gears 18. The three fourth gears 18 are meshed with the gear rings 15.
[0028] One end of the mounting plate 20 penetrates the side wall of the tank 1 and is slidably connected to the tank 1. The baffle plate 16 and the placement box 19 are both provided with placement grooves 21 that are adapted to the mounting plate 20. The bottom end of the baffle plate 16 is provided with a collection port 22. The waste acid inside the tank 1 rotates counterclockwise with the agitation of the first stirring impeller 6. The collection port 22 is located on the side of the baffle plate 16 that collides with the water flow, so that the impurities settled at the bottom of the tank 1 enter the bottom of the screw rod 17 with the direction of the water flow.
[0029] The mounting plate 20 is slidably connected to the inside of the two placement slots 21. The mounting plate 20 has an installation slot inside, and the filter element 23 is installed inside the installation slot. The worker can pull the mounting plate 20 out of the placement slot 21, so that the worker can easily replace the filter element 23.
[0030] It should be noted that this utility model is an industrial waste acid recovery and impurity removal device. First, the waste acid is stored inside the tank 1. During operation, the motor 2 is started, and then the required weight of reaction materials for the waste acid is poured into the feed cylinder 8 through the feed inlet. The motor 2 drives the second gear 5 and the transmission gear 13 to rotate simultaneously via the first gear 3. The second gear 5 drives the second stirring blade 7 to rotate counterclockwise via the rotating shaft 4. The transmission gear 13 drives the feed cylinder 8 to rotate clockwise via the third gear 11. A stirring rod 9 is fixedly connected inside the feed cylinder 8, along with the second stirring blade 7. During rotation, the raw materials are dispersed and evenly distributed on the top of the material cone wheel 10. As the rotating shaft 4 rotates, it drives the material cone wheel 10 to rotate as well. Through the material cone wheel 10, the raw materials are evenly thrown onto the wastewater surface along the inclined surface of the material cone wheel 10, thereby improving the uniformity of the material distribution and preventing a large amount of raw materials from contacting the waste acid liquid surface at the same time, which would lead to excessively high local concentration of raw materials in the waste acid and thus affect the reaction effect between the wastewater and the raw materials. At the same time, the raw materials stick together and clump together after encountering water, forming a large amount of sediment, which not only wastes raw materials but also easily clogs the filter element 23.
[0031] When the rotating shaft 4 rotates, it drives the first stirring impeller 6 to rotate, thereby stirring the waste acid. The baffle 16 collides with the water flow that follows the first stirring impeller 6, thereby improving the mixing efficiency of the raw material and the waste acid, allowing the raw material to fully contact and react with the waste acid, and thus improving the removal efficiency of impurities. The collection port 22 is located at the bottom of the baffle 16 on the side that collides with the water flow. The reaction between the raw material and the waste acid causes the impurities in the waste acid to precipitate. When the impurities precipitate at the bottom of the tank 1, they enter the collection port 22 along the bottom edge of the tank 1 under the action of gravity and centrifugal force. At the same time, the feed cylinder 8 rotates, driving the fourth gear 18 to rotate through the gear ring 15. The fourth gear 18 drives the spiral rod 17 inside the baffle 16 to rotate. The spiral rod 17 sucks up the impurities precipitated at the bottom of the tank 1, thereby transporting the impurities to the inside of the filter element 23 for filtration and collection.
[0032] The filter element 23 is fixed inside the filter element 23. The mounting plate 20 is slidably connected to the placement groove 21. Workers can quickly replace the filter element 23 by pulling out the mounting plate 20, which facilitates the daily cleaning and replacement of the filter element 23 and reduces the workload of workers.
[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
