Description

Technical Field

[0001] The present invention belongs to the technical field of tannic acid waste liquid treatment, and specifically relates to a purification device for tannic acid production wastewater. Background Art

[0002] The purification device for tannic acid production wastewater integrates a variety of wastewater treatment technologies, aiming to effectively remove harmful substances in the wastewater, recover valuable components (such as tannic acid), and ensure that the treated wastewater meets the discharge standards. Adding chemical agents to the produced wastewater can improve the purification effect, remove specific pollutants, or adjust the water quality. These agents play a crucial role in wastewater treatment. They can help remove pollutants such as suspended solids, organic matter, and heavy metal ions in the wastewater, and at the same time adjust parameters such as the pH value and redox potential of the wastewater to achieve the purpose of purifying the water quality.

[0003] Some solutions have also been proposed in the prior art. For example, a patent with the publication number CN117658349A discloses a tannic acid production waste liquid treatment device, including a reaction cylinder, an anti-backflow component fixedly connected to the bottom of the reaction cylinder, a power module for driving the bidirectional screw in the anti-backflow component, and a mixing component circumferentially arranged at the top of the anti-backflow component, which is used to block the waste liquid vortex inside the reaction cylinder and generate a vortex flow. By blocking the waste liquid vortex inside the reaction cylinder and generating a vortex flow through the mixing component, the aeration range of the device is increased, and the problems in the prior art that the waste liquid is prone to backflow and the aeration range is small when aerating the tannic acid waste liquid are solved.

[0004] When the existing device treats the wastewater produced by tannic acid production, specific agents are added to remove pollutants such as suspended solids, organic matter, and heavy metal ions in the wastewater. And currently, when adding agents to the wastewater treatment device, the agents are usually added into the reaction cylinder through a certain fixed position, and then stirred to fully mix and react with the wastewater. Since the agents are added to the reaction cylinder through a fixed point, it will cause uneven distribution of the agents in the wastewater, and there will still be a phenomenon of too high or too low local agent concentration after stirring, which affects the effect of wastewater treatment.

[0005] Therefore, the present invention provides a purification device for tannic acid production wastewater. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0031] As Figures 1 to 7As shown in the figure, the present invention provides a technical solution: a purification device for tannic acid production wastewater, including a reaction cylinder 1. One side above the reaction cylinder 1 is fixedly communicated with a liquid inlet pipe 2, and the outer wall of the liquid inlet pipe 2 is fixedly connected with a liquid inlet valve 3. The bottom of the reaction cylinder 1 is fixedly communicated with a liquid outlet chamber 4, and the outer wall of the liquid outlet chamber 4 is fixedly connected with a liquid outlet valve 5. A fixing frame 6 is fixedly installed on the outer wall of the reaction cylinder 1. The top of the reaction cylinder 1 is symmetrically and fixedly communicated with an air outlet pipe 27. A liquid distribution component is arranged inside the reaction cylinder 1, and the liquid distribution component is used to add the medicament to various areas inside the reaction cylinder 1. A stirring component is arranged outside the liquid distribution component, and the stirring component is used to stir the medicament and the wastewater for thorough mixing. A scraping component is arranged inside the reaction cylinder 1, and the scraping component is used to remove the impurities on the bottom surface of the inner wall of the reaction cylinder 1.

[0032] During operation: Before wastewater treatment, open the liquid inlet valve 3, and add the wastewater generated during the tannic acid production process into the reaction cylinder 1 through the liquid inlet pipe 2. When the amount of wastewater in the reaction cylinder 1 reaches an appropriate capacity, close the liquid inlet valve 3.

[0033] When carrying out wastewater treatment work, first add the medicament to various areas inside the reaction cylinder 1 through the liquid distribution component. After the medicament is added, the stirring component quickly stirs the medicament and the wastewater for thorough mixing. During the stirring process, the medicament reacts with pollutants such as suspended substances, organic substances, and heavy metal ions in the wastewater. The reaction will generate a small amount of bubbles and impurities. The bubbles will rise to the water surface and be discharged through the air outlet pipe 27, while the impurities will fall to the bottom of the reaction cylinder 1 to form precipitates. After the reaction is completed, open the liquid outlet valve 5, and the treated wastewater will flow out through the liquid outlet chamber 4 for subsequent other treatments. And during the liquid discharge process, through the scraping component, the precipitates formed at the bottom of the reaction cylinder 1 will not adhere to its inner wall, and all the precipitates can be completely discharged through the liquid outlet chamber 4, keeping the reaction cylinder 1 in a clean state.

[0034] Through the above embodiments, the medicament is added to various area positions inside the reaction cylinder 1 through the liquid distribution component. The distribution of the medicament in various areas of the reaction cylinder 1 can ensure that the pollutants in the wastewater are in full contact with the medicament, avoiding the situation of too high or too low local medicament concentration. Cooperating with the arranged stirring component for thorough mixing, it is ensured that the wastewater in the entire reaction cylinder 1 can be effectively treated, thereby optimizing the reaction effect and improving the quality of wastewater treatment.

[0035] Such as Figures 4 to 6As shown in the figure, the liquid separation component includes a liquid storage cylinder 7. The top end of the liquid storage cylinder 7 is rotatably connected to the inner wall of the top surface of the reaction cylinder 1, and the bottom end of the liquid storage cylinder 7 is rotatably connected to the inner wall of the bottom surface of the reaction cylinder 1. Moreover, the liquid storage cylinder 7 is located at the central position of the reaction cylinder 1. A plurality of groups of liquid outlet holes 8 are evenly arranged on the outer wall of the liquid storage cylinder 7. The number of each group of liquid outlet holes 8 is several and they are longitudinally and evenly arranged on the surface of the liquid storage cylinder 7. A spraying component is arranged inside the liquid storage cylinder 7, and the spraying component is used to enable the medicament to be sprayed out from each liquid outlet hole 8.

[0036] During operation: When the medicament is added to the designated position inside the liquid storage cylinder 7, the spraying component is started. The spraying component will enable the medicament to be sprayed out simultaneously through each group of several liquid outlet holes 8. Since the liquid storage cylinder 7 is located at the central position of the reaction cylinder 1, and each group of liquid outlet holes 8 is evenly distributed on the outer wall of the liquid storage cylinder 7, and several liquid outlet holes 8 in each group are longitudinally and evenly arranged on the surface of the liquid storage cylinder 7, the medicament sprayed out through each liquid outlet hole 8 will be distributed in each area inside the reaction cylinder 1, thus achieving the effect of the medicament contacting the wastewater in each area.

[0037] As Figures 4 to 6 shown in the figure, the spraying component includes a rotating shaft 9. The rotating shaft 9 is located inside the liquid storage cylinder 7 and its two ends are respectively rotatably connected to the inner walls of the top surface and the bottom surface of the reaction cylinder 1. A motor 17 is fixedly installed at the bottom of the reaction cylinder 1, and the output shaft of the motor 17 is fixedly connected to one end of the rotating shaft 9. A plurality of fixed push plates 11 are fixedly connected to the outer wall of the rotating shaft 9. The end of the fixed push plate 11 away from the rotating shaft 9 is an arc surface and is attached to the inner wall of the liquid storage cylinder 7. A plurality of blocking plates 10 are arranged on the inner wall of the liquid storage cylinder 7. One side of the plurality of blocking plates 10 is an arc surface and is respectively attached to one side of each group of liquid outlet holes 8, and the other side of the plurality of blocking plates 10 is attached to the outer wall of the rotating shaft 9. A liquid storage chamber 13 is formed in the area between each fixed push plate 11 and the blocking plate 10. An inlet liquid component for adding the medicament into each liquid storage chamber 13 is arranged above the liquid storage chamber 13. A linkage component is arranged between each fixed push plate 11 and the blocking plate 10.

[0038] During operation: In the initial state, each blocking plate 10 is located on one side of each group of liquid outlet holes 8. Since one side of the blocking plate 10 is an arc surface and is respectively attached to one side of each group of liquid outlet holes 8, each liquid outlet hole 8 is in a closed state, and the wastewater will not enter the inside of the liquid storage cylinder 7.

[0039] Through the liquid inlet assembly, the medicament is evenly added into each liquid storage chamber 13, that is, between the blocking baffle 10 and the fixed push plate 11. Then, the motor 17 is started, and its output shaft drives the rotating shaft 9 to rotate. When the rotating shaft 9 rotates, it drives each fixed push plate 11 to rotate around the rotating shaft 9 and along the inner wall of the liquid storage cylinder 7. When the fixed push plate 11 starts to rotate, it drives the blocking baffle 10 to rotate together through the linkage assembly. After the blocking baffle 10 rotates a certain angle, each liquid outlet hole 8 is just in the open state, and at this time, the blocking baffle 10 can no longer rotate. When the rotating shaft 9 continues to drive multiple fixed push plates 11 to rotate, the fixed push plates 11 gradually fit with the blocking baffle 10. When the fixed push plates 11 gradually rotate and fit with the blocking baffle 10, due to the generated extrusion force, the medicament between the liquid storage chambers 13 is ejected from one side of several liquid outlet holes 8. When the fixed push plates 11 and the blocking baffle 10 are completely fitted, the medicament between each liquid storage chamber 13 is all ejected, thus realizing the effect that the medicament is evenly distributed in each area inside the reaction cylinder 1.

[0040] It should be noted that during each wastewater treatment, the wastewater to be treated inside the reaction cylinder 1 and the medicament to be ejected from the liquid storage cylinder 7 are both in a filled state. Filling the medicament can ensure that when the blocking baffle 10 and the fixed push plate 11 rotate, the medicament can be effectively extruded, thereby ensuring that the medicament can be effectively ejected. Filling the wastewater can ensure that the ejected medicament can cover each area of the wastewater.

[0041] As Figures 4 to 6 shown, the linkage assembly includes multiple groups of arc-shaped push rods 14. The number of each group of arc-shaped push rods 14 is several. One side of each fixed push plate 11 is respectively fixedly connected to one end of each group of arc-shaped push rods 14. The outer walls of each group of several arc-shaped push rods 14 are respectively inserted into the inner walls of each blocking baffle 10. High-strength springs 15 are arranged outside the arc-shaped push rods 14. One end of each high-strength spring 15 is fixedly connected to one side of the blocking baffle 10, and the other end of each high-strength spring 15 is fixedly connected to a frustum-shaped block 16. One side of each frustum-shaped block 16 is fixedly connected to the end of the arc-shaped push rod 14 far from the fixed push plate 11. A plurality of limiting blocks 12 are fixedly connected to the inner wall of the liquid storage cylinder 7, and the plurality of limiting blocks 12 are respectively located on one side of the plurality of blocking baffles 10.

[0042] During operation: At the beginning, when the rotating shaft 9 rotates and drives the fixed push plate 11 to rotate, the fixed push plate 11 will drive the blocking baffle 10 to rotate through the arc-shaped push rod 14. And due to the high-strength spring 15 provided, when the fixed push plate 11 pushes the blocking baffle 10 to rotate, the high-strength spring 15 will not deform. And when the blocking baffle 10 rotates to fit one side of the limit block 12, the fixed push plate 11 cannot push the blocking baffle 10 to rotate anymore when it continues to rotate. And at this time, the fixed push plate 11 will gradually approach the blocking baffle 10. Since the liquid outlet holes 8 are no longer closed after the blocking baffle 10 rotates, when the fixed push plate 11 gradually approaches the blocking baffle 10, the medicine in the liquid storage chamber 13 will be ejected from each liquid outlet hole 8. When the fixed push plate 11 rotates to fit the blocking baffle 10, all the medicine is squeezed out. At this time, when the motor 17 drives the rotating shaft 9 to continue rotating, it will drive the entire liquid storage cylinder 7 to rotate.

[0043] As Figures 4 to 6 shown, the length of the arc-shaped end of the blocking baffle 10 is slightly larger than the outer diameter of the liquid outlet hole 8, and the distance between the side of the blocking baffle 10 close to the limit block 12 and the limit block 12 is the same as the thickness of the blocking baffle 10.

[0044] During operation: The length of the arc-shaped end of the blocking baffle 10 is slightly larger than the outer diameter of the liquid outlet hole 8, so that the blocking baffle 10 can just block one side of the liquid outlet hole 8 in the initial state. And by setting the distance between the side of the blocking baffle 10 close to the limit block 12 and the limit block 12 to be the same as the thickness of the blocking baffle 10, when the blocking baffle 10 fits the limit block 12, the liquid outlet hole 8 can just be completely opened. And when the fixed push plate 11 rotates to fit the blocking baffle 10, it can just squeeze out all the medicine in the liquid storage chamber 13.

[0045] As Figures 2 to 3 shown, a blocking circular plate 18 is rotatably connected to the top of the liquid storage cylinder 7, and the blocking circular plate 18 is fixedly installed on the top of the reaction cylinder 1.

[0046] During operation: Through the provided blocking circular plate 18, the top of the entire liquid storage cylinder 7 is blocked, so that when the fixed push plate 11 rotates and gradually approaches the blocking baffle 10 to squeeze the medicine, the medicine will not overflow from the top of the liquid storage cylinder 7, but will only spray out from one side of each liquid outlet hole 8.

[0047] As Figures 2 to 3 shown, the liquid inlet assembly includes a liquid medicine tank 19, the liquid medicine tank 19 is fixedly installed on the top of the reaction cylinder 1, the bottom of the liquid medicine tank 19 is fixedly connected with a plurality of connecting pipes 20, the outer walls of the plurality of connecting pipes 20 are respectively inserted into the inner wall of the blocking circular plate 18, the outlets of the plurality of connecting pipes 20 are all located directly above the liquid storage chamber 13, and one-way valves 21 are arranged outside the plurality of connecting pipes 20.

[0048] During operation: By opening each one-way valve 21, the medicament in the medicament tank 19 can uniformly enter each liquid storage chamber 13 through a plurality of connecting pipes 20. And due to the one-way valves 21 provided, when the fixed push plate 11 rotates and gradually approaches the blocking baffle 10 to squeeze the medicament, the medicament will not flow back to the medicament tank 19 through the connecting pipes 20, but can only be ejected from one side of each liquid outlet hole 8.

[0049] As Figure 3 and Figure 7 As shown, a plurality of stirring rods 22 are uniformly and fixedly connected to the outer wall of the liquid storage cylinder 7, and a plurality of stirring blades 23 are fixedly connected to the outer walls of the plurality of stirring rods 22.

[0050] During operation: When the fixed push plate 11 rotates to fit with the blocking baffle 10 so that all the medicament is extruded, when the motor 17 drives the rotating shaft 9 to continue rotating, the fixed push plate 11 and the blocking baffle 10 cannot rotate further due to the limitation of the limiting block 12 at this time. And the fixed push plate 11 will transfer the rotational force to the liquid storage cylinder 7 through the limiting block 12, causing the liquid storage cylinder 7 to rotate inside the reaction cylinder 1. When the liquid storage cylinder 7 rotates, it will drive a plurality of stirring rods 22 and stirring blades 23 to rotate, enabling the medicament to fully mix with the wastewater and react. And the whole rotation process is integrated. After all the medicament is added, the stirring and mixing operation can be carried out immediately, thereby optimizing the reaction time of the entire wastewater treatment. When the medicament is mixed with the wastewater, the chemical reaction can reach the equilibrium state faster, thereby shortening the reaction time and improving the efficiency of wastewater treatment.

[0051] As Figure 3 and Figure 7 As shown, one end of each stirring rod 22 far from the liquid storage cylinder 7 fits with the inner wall of the reaction cylinder 1, and a gear 24 is fixedly connected to the outer wall of each stirring rod 22. A plurality of annular rack plates 25 are fixedly installed on the inner wall of the reaction cylinder 1, and the teeth of the annular rack plates 25 mesh and match with the teeth of the gears 24.

[0052] During operation: When the stirring rods 22 and the stirring blades 23 revolve around the liquid storage cylinder 7 as the axis on the inner wall of the reaction cylinder 1, a meshing relationship will occur between the gears 24 and the annular rack plates 25, causing the stirring rods 22 and the stirring blades 23 to rotate. With the cooperation of revolution and rotation, the stirring effect of the stirring blades 23 is better, and the reaction between the medicament and the wastewater is more sufficient.

[0053] As Figures 2 to 3 As shown, a plurality of scraping plates 26 are fixedly connected to the bottom outer wall of the liquid storage cylinder 7, and the bottoms of the plurality of scraping plates 26 respectively fit with the inner wall of the bottom surface of the reaction cylinder 1.

[0054] During operation: When the liquid storage cylinder 7 rotates, multiple scraping plates 26 will rotate around the liquid storage cylinder 7 as the axis. Since the bottom of the scraping plate 26 is in contact with the inner wall of the bottom surface of the reaction cylinder 1, when the scraping plate 26 rotates, it can continuously scrape off the precipitates generated by the reaction and falling to the bottom of the reaction cylinder 1, preventing the precipitates from adhering to the inner wall surface of the reaction cylinder 1 and causing them to not all flow out from the liquid outlet chamber 4.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
