Description

Technical Field

[0001] This invention relates to the field of wastewater deodorization technology, and in particular to a wastewater pond deodorization device and method. Background Technology

[0002] Water pollution is mainly caused by pollutants generated by human activities. It includes four main sources: mining pollution, industrial pollution, agricultural pollution, and domestic pollution. Before treating water pollution, wastewater needs to be discharged into a wastewater pond. Since wastewater comes from various parts of life, it contains many chemical substances that will produce odors after reactions. Decomposition and other phenomena also increase the odor. In order to ensure the overall improvement of environmental quality and sustainable development, wastewater needs to be comprehensively and collaboratively controlled and remediated to ensure the effectiveness of integrated pollution control. In the treatment process, flocculants and deodorizers are generally added to the wastewater to react with it and thus remove the odor.

[0003] In existing technologies, flocculants and deodorizers need to be added to wastewater when deodorizing it. However, the flocculants and deodorizers are generally not preheated before being added to the wastewater. As a result, the flocculant and deodorizer molecules do not have initial energy when they are added to the wastewater. Therefore, when the flocculant and deodorizer molecules react with odor substances, they require more activation energy, which reduces the reaction rate.

[0004] Furthermore, when flocculants and deodorizers are added, the wastewater is in a flowing state. When the flocculants and deodorizers are added to the flowing wastewater, their concentration will be diluted, which will affect the reaction between the flocculants and deodorizers and the odor substances in the wastewater, and will also make it impossible to perform quantitative deodorization treatment, thus affecting the deodorization effect. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art by proposing a wastewater deodorization device and method.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a sewage tank deodorization device, comprising a deodorization chamber, wherein the deodorization chamber is provided with a quantitative deodorization mechanism, a quantitative addition mechanism and a preheating mixing mechanism;

[0007] The quantitative deodorization mechanism includes a deodorization cavity inside the deodorization chamber for storing a fixed amount of wastewater. The preheating and mixing mechanism includes placement slots communicating with both sides of the inner wall of the deodorization cavity. Piston plates are provided on the outer walls of the two placement slots on opposite sides. Hollow shafts are rotatably passed through the two piston plates. Multiple rotating sleeves are fixedly connected to the outer walls of the two hollow shafts. The quantitative addition mechanism is used to add deodorant and flocculant quantitatively into the placement slots. While the hollow shafts and rotating sleeves rotate, hot air is introduced into the placement slots to preheat the deodorant and flocculant. When the piston plates move into the deodorization cavity, the preheated deodorant and flocculant gradually enter the wastewater. At the same time, the rotating sleeves contact and agitate the wastewater, mixing it with the deodorant and flocculant.

[0008] Preferably, the preheating mixing mechanism further includes three-stage cylinders A fixedly connected to the left and right ends of the deodorizing chamber. Each of the two three-stage cylinders A has a connecting plate A fixedly connected to its telescopic end. Each of the two connecting plates A has a guide rod A fixedly connected symmetrically to one end close to the other. Both sets of guide rods A penetrate the deodorizing chamber. The two guide rods A and two piston plates are fixedly connected respectively. Each set of guide rods A has a limit block fixedly connected to its outer wall.

[0009] Preferably, the preheating mixing mechanism further includes an annular groove formed on the inner wall of the piston plate. A flexible hose is fixedly inserted between the two sets of piston plates, guide rod A and connecting plate A. The flexible hose delivers hot air into the annular groove and into the rotating sleeve through the hole on the hollow shaft. A motor is fixedly connected to one end of each of the two piston plates away from each other. The drive ends of the two motors are fixedly connected to the two hollow shafts respectively.

[0010] Preferably, each of the rotating sleeves has an extension plate slidably disposed on its inner wall, and a second tension spring is fixedly connected to one end of the inner side of each extension plate. Each second tension spring is fixedly connected to the inner wall of each rotating sleeve. A circular plate is fixedly connected to one end of each of the two hollow shafts that are close to each other. A notch adapted to the shape of the circular plate is opened on one side of each of the two placement slots that are close to each other.

[0011] Preferably, a discharge hole is provided on one side of the bottom of the deodorizing cavity. The discharge hole and the two placement slots are connected through a leakage hole. The bottom of the inner wall of each of the two placement slots is provided with a movable slot. An electric telescopic rod is fixedly connected to one end of each of the two movable slots away from each other. A sealing block is fixedly connected to the telescopic end of each of the two electric telescopic rods to block the leakage hole and prevent the deodorizer and flocculant from flowing into the leakage hole.

[0012] Preferably, the quantitative deodorization mechanism further includes a water inlet passing through the front end of the deodorization chamber, the water inlet being provided with a closed structure A, and a three-stage cylinder B fixedly connected to the rear end of the deodorization chamber. The telescopic end of the three-stage cylinder B is fixedly connected to a connecting plate B, and the end of the connecting plate B near the deodorization chamber is symmetrically fixedly connected to guide rods B. Both guide rods B pass through the deodorization chamber, and the other ends of the two guide rods B are fixedly connected to a moving ring. A square piston is fixedly connected to the outer wall of the moving ring, the square piston being adapted to the shape of the deodorization cavity, and a closed structure B is provided at one end of the moving ring.

[0013] Preferably, the quantitative addition mechanism includes a feed hole at the top of the placement groove, two feed holes connected to square cavities, a dispensing column on the inner wall of each of the two square cavities, a quantitative hole on each of the two dispensing columns, a circular groove connected to one end of each of the two square cavities, a first tension spring fixedly connected between each of the two sets of circular grooves and dispensing columns, square grooves on both sides of the top of the deodorizing box, and a storage hopper fixedly connected to the bottom of each of the two square grooves and connected to the square cavity.

[0014] Preferably, the quantitative addition mechanism further includes a rotating shaft rotatably connected to the middle of the top of the deodorizing box, two winding drums are fixedly connected to the outer wall of the rotating shaft, and ropes are fixedly connected to the outer walls of the two winding drums. The two ropes and the two component columns are respectively fixedly connected to and pass through the deodorizing box.

[0015] Preferably, two electric push rods are fixedly connected to one side of the top of the deodorizing box corresponding to the rotating shaft. The telescopic ends of the two electric push rods are fixedly connected to a limiting frame. The limiting frame is slidably connected to the deodorizing box. An L-shaped rod is slidably connected to one end of the limiting frame near the rotating shaft. A toothed plate is fixedly connected to one end of the L-shaped rod. A gear is meshed with one end of the toothed plate near the rotating shaft. The gear is fixedly connected to the rotating shaft. The rotating shaft is slidably connected to the connecting plate B.

[0016] Preferably, a method for deodorizing a sewage tank includes the following steps:

[0017] Step 1: First, the wastewater is pumped into the deodorization cavity through the quantitative deodorization mechanism to complete quantitative storage. At the same time, the quantitative addition mechanism adds the deodorizing agent and flocculant into the placement tank in a quantitative manner and preheats them.

[0018] Step 2: After preheating, the deodorizer and flocculant in the placement tank are squeezed into the deodorization cavity through the piston plate, and the deodorizer and flocculant are mixed and reacted with the sewage. The reaction is heated to increase the reaction rate.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By setting up a preheating mixing mechanism, the flocculant and deodorizer can be preheated before being added to the wastewater. This allows the flocculant and deodorizer molecules to gain initial energy, reducing the activation energy required to react with odor substances and thus accelerating the reaction rate. Furthermore, when the flocculant and deodorizer are fed into the wastewater, the wastewater can be stirred and heated simultaneously, which also expands the stirring area and further accelerates the reaction rate, thereby improving the overall pollution control effect.

[0021] 2. By setting up a quantitative deodorization mechanism, sewage can be pumped into a quantitative deodorization cavity, thereby avoiding the flow of sewage. Therefore, when flocculants and deodorizers are added to stagnant sewage, the concentration will not decrease, ensuring that the flocculants and deodorizers react fully with the odor substances in the sewage.

[0022] 3. Through the setting of the quantitative addition mechanism, flocculants and deodorizers can be added to the wastewater in a quantitative and stable manner. The added flocculants and deodorizers can react completely with the odor substances in the wastewater. At this time, the flocculants and deodorizers react completely with the odors, leaving no residue, thus avoiding the discharge of residues and improving the deodorization effect.

[0023] 4. When the quantitative deodorization mechanism pumps wastewater into the deodorization cavity in a quantitative manner, it will drive the quantitative addition mechanism to move, thereby completing the quantitative addition of flocculant and deodorant. Due to the linkage between the mechanisms, the overall linkage effect can be increased. Attached Figure Description

Detailed Implementation

[0036] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0037] like Figures 1-11The wastewater deodorization device shown includes a deodorization chamber 1, which is equipped with a quantitative deodorization mechanism, a quantitative addition mechanism, and a preheating and mixing mechanism. The quantitative deodorization mechanism includes a deodorization cavity 21 inside the deodorization chamber 1, which is used to store a specific amount of wastewater. The preheating and mixing mechanism includes placement slots 23 communicating with both sides of the inner wall of the deodorization cavity 21. Piston plates 26 are provided on the opposite sides of the inner walls of the two placement slots 23. Hollow shafts 24 rotatably pass through both piston plates 26. The outer walls of the two hollow shafts 24 are fixed. Multiple rotating sleeves 30 are fixedly connected. A metering addition mechanism is used to add deodorant and flocculant into the placement tank 23 in a metered manner. While the hollow shaft 24 and the rotating sleeves 30 rotate, hot air is introduced into the tank to preheat the deodorant and flocculant in the placement tank 23. When the piston plate 26 moves into the deodorization cavity 21, the preheated deodorant and flocculant gradually enter the wastewater. At the same time, the rotating sleeves 30 contact and agitate the wastewater, and mix the wastewater with the deodorant and flocculant. The deodorant and flocculant used can be in powder or liquid form.

[0038] like Figure 1 , Figure 2 , Figure 4 As shown, the preheating mixing mechanism also includes three-stage cylinders A2 fixedly connected to the left and right ends of the deodorizing chamber 1. Each of the two three-stage cylinders A2 has a connecting plate A6 fixedly connected to its telescopic end. Each of the two connecting plates A6 has a guide rod A4 symmetrically fixedly connected to one end of each other. Both sets of guide rods A4 penetrate the deodorizing chamber 1. The two guide rods A4 are fixedly connected to two piston plates 26 respectively. A limit block 3 is fixedly connected to the outer wall of each set of guide rods A4. By setting the limit block 3, the piston plate 26 can be positioned precisely near the notch.

[0039] like Figure 2 , Figure 4 , Figure 9 As shown, the preheating mixing mechanism also includes an annular groove 42 formed on the inner wall of the piston plate 26. A flexible hose 5 is fixedly inserted between the two sets of piston plates 26, the guide rod A4, and the connecting plate A6. The hose 5 delivers hot air into the annular groove 42 and then into the rotating sleeve 30 through holes in the hollow shaft 24. Motors 25 are fixedly connected to the ends of the two piston plates 26 that are furthest apart from each other. The drive ends of the two motors 25 are fixedly connected to the two hollow shafts 24. The hose 5 connects to an external hot air blower to provide heat and to perform heating treatment during mixing, thus achieving multiple uses of heat.

[0040] like Figure 4 , Figure 9 , Figure 10As shown, each rotating sleeve 30 has an extension plate 44 slidably mounted on its inner wall. A second tension spring 43 is fixedly connected to one end of the inner side of each extension plate 44. Each second tension spring 43 is fixedly connected to the inner wall of each rotating sleeve 30. When each extension plate 44 extends beyond the range of the rotating sleeve 30, the rotation area is increased. Two hollow shafts 24 have circular plates 22 fixedly connected to their respective ends near each other. The inner walls of the two placement grooves 23 each have notches on their respective sides near each other, matching the shape of the circular plates 22. The tight fit between the circular plates 22 and the notches prevents wastewater from entering the placement grooves 23 during extraction, thus avoiding affecting the volume of the wastewater.

[0041] like Figure 6 , Figure 7 As shown, a discharge hole 34 is provided on one side of the bottom of the deodorizing cavity 21. The discharge hole 34 and the two placement slots 23 are connected through a leakage hole 33. A movable slot 35 is provided at the bottom of the inner wall of each of the two placement slots 23. An electric telescopic rod 36 is fixedly connected to one end of each movable slot 35, away from each other. A sealing block 32 is fixedly connected to the telescopic end of each electric telescopic rod 36 to block the leakage hole 33, preventing the deodorizer and flocculant from flowing into the leakage hole 33. This avoids affecting the quantity of deodorizer and flocculant and ensures the reaction effect.

[0042] like Figure 2 , Figure 4 , Figure 5 As shown, the quantitative deodorization mechanism also includes a water inlet 20 passing through the front end of the deodorization chamber 1, with a closed structure A27 on the water inlet 20, and a three-stage cylinder B9 fixedly connected to the rear end of the deodorization chamber 1. A connecting plate B8 is fixedly connected to the telescopic end of the three-stage cylinder B9. Guide rods B7 are symmetrically fixedly connected to one end of the connecting plate B8 near the deodorization chamber 1. Both guide rods B7 pass through the deodorization chamber 1. A moving ring 28 is fixedly connected to the other end of the two guide rods B7. A square piston 29 is fixedly connected to the outer wall of the moving ring 28. The square piston 29 is adapted to the shape of the deodorization cavity 21. A closed structure B31 is provided at one end of the moving ring 28.

[0043] like Figure 7 , Figure 8 As shown, the quantitative addition mechanism includes a feed hole 39 at the top of the placement groove 23. Both feed holes 39 are connected to square cavities 37. The inner walls of both square cavities 37 are provided with dispensing columns 38. Each dispensing column 38 is provided with a quantitative hole 40. Each of the two square cavities 37 is connected to a circular groove at one end. A first tension spring 41 is fixedly connected between the two sets of circular grooves and the dispensing columns 38. Square grooves 13 are provided on both sides of the top of the deodorizing box 1. The bottom ends of the two square grooves 13 are fixedly connected to storage hoppers 12 and connected to the square cavities 37.

[0044] like Figure 1 , Figure 2 , Figure 7 As shown, the quantitative addition mechanism also includes a rotating shaft 11 rotatably connected to the center of the top of the deodorizing chamber 1. Two winding drums 15 are fixedly connected to the outer wall of the rotating shaft 11, and ropes 14 are fixedly connected to the outer walls of both winding drums 15. The two ropes 14 and two component columns 38 are respectively fixedly connected to and pass through the deodorizing chamber 1. The ropes 14 facilitate repositioning and pulling, and the position of the ropes 14 is restricted by the upright plate, so that the ropes 14 on both sides are aligned with the center position of the two winding drums 15, which facilitates the winding operation of the ropes 14.

[0045] like Figure 1 , Figure 2 As shown, two electric push rods 17 are fixedly connected to one side of the top of the deodorizing box 1 corresponding to the rotating shaft 11. The telescopic ends of the two electric push rods 17 are fixedly connected to the limit frame 16. The limit frame 16 and the deodorizing box 1 are slidably connected. An L-shaped rod 10 is slidably connected to one end of the limit frame 16 near the rotating shaft 11. A toothed plate 19 is fixedly connected to one end of the L-shaped rod 10. A gear 18 is meshed with one end of the toothed plate 19 near the rotating shaft 11. The gear 18 and the rotating shaft 11 are fixedly connected. The rotating shaft 11 and the connecting plate B8 are slidably connected.

[0046] A method for deodorizing a sewage tank includes the following steps:

[0047] Step 1: First, the wastewater is pumped into the deodorization cavity 21 through the quantitative deodorization mechanism to complete the quantitative storage. At the same time, the quantitative addition mechanism adds the deodorizing agent and flocculant into the placement tank 23 in a quantitative manner and preheats them.

[0048] Step 2: After preheating, the deodorizer and flocculant in the placement tank 23 are squeezed into the deodorization cavity 21 through the piston plate 26, and the deodorizer and flocculant are mixed and reacted with the sewage. During the reaction, the mixture is heated to increase the reaction rate.

[0049] Working principle: First, the flocculant and deodorizer are poured into the storage hoppers 12 on both sides. Then, the three-stage cylinder B9 is activated, pushing the connecting plate B8 away from the deodorizing chamber 1. This moves the guide rod B7 and the moving ring 28. Because the square piston 29 and the inner wall of the deodorizing cavity 21 are tightly fitted, a negative pressure is generated when the square piston 29 moves. This opens the closed structure A27, allowing sewage to pass through the inlet 20 and enter the deodorizing cavity 21. At the same time, the connecting plate B8 moves the L-shaped rod 10 and the toothed plate 19. When the toothed plate 19 and the gear 18 mesh... When they are together, the horizontal motion is converted into rotational motion. At this time, the gear 18 rotates the shaft 11 and the winding drum 15, so the rope 14 can be wound up. Since the rope 14 and the component column 38 are fixed together, the component column 38 can be pulled to one side and the first tension spring 41 is stretched. At this time, the metering holes 40 on both sides are filled with a certain amount of flocculant and deodorant respectively. When the metering hole 40 and the feed hole 39 are aligned, the flocculant and deodorant fall into the placement groove 23. When the gear 18 and the tooth plate 19 are separated, the component column 38 can be automatically reset by the elastic reset action of the first tension spring 41.

[0050] After the flocculant and deodorizer enter the placement tank 23, hot air is delivered into the annular tank 42 through the hose 5 by an external hot air blower. The holes in the hollow shaft 24 allow the hot air to enter the rotating sleeve 30. Simultaneously, the motor 25 rotates the hollow shaft 24, transferring heat to the flocculant and deodorizer for preheating. This allows the flocculant and deodorizer molecules to gain initial energy, reducing the activation energy required for reaction with odorous substances and accelerating the reaction rate. The presence of the placement tank 23 restricts the extension plate 44, ensuring it remains within the tank. Then, the connecting plate B8 continues to move, filling the entire deodorizing cavity 21 with wastewater. This completes the quantitative extraction of wastewater, preventing its flow. Therefore, when the flocculant and deodorizer are added to still wastewater, their concentration is not reduced, ensuring a full reaction between the flocculant and deodorizer and the odorous substances in the wastewater. Simultaneously, the square piston 29 covers the top of the discharge port 34 to prevent leakage.

[0051] When the third-stage cylinder A2 moves the connecting plate A6 towards the deodorization chamber 1, it moves the guide rod A4 and pushes the piston plate 26 inward. At this time, the preheated flocculant and deodorant begin to contact the sewage. The guide rod A4 is limited by the limit block 3, so that the piston plate 26 reaches the position close to the notch. At this time, the sewage can be stirred and heated at the same time, which can also expand the stirring area and further accelerate the reaction rate, thereby improving the overall pollution control effect. After the quantitative sewage treatment is completed, the hot air supply is turned off. At this time, the extension plate 44 can be stored in the rotating sleeve 30 by the elastic reset action of the second tension spring 43 to avoid affecting the storage of the rotating sleeve 30. Then, the third-stage cylinder is started in reverse. A2 resets the piston plate 26 and tightly clamps the circular plate 22 onto the notch, completing the sealing operation. At this time, the electric telescopic rod 36 is activated, moving the sealing block 32 to one side and opening the leakage hole 33. Therefore, the sewage entering the placement tank 23 flows into the discharge hole 34 through the leakage hole 33. Then, the electric push rod 17 is activated, moving the limit frame 16 away from the rotating shaft 11, and the three-stage cylinder B9 is activated in the opposite direction, moving the connecting plate B8 towards the deodorization box 1. At this time, the closed structure B31 is in the open state, allowing the treated sewage to flow out through the discharge hole 34, facilitating the extraction of the next sewage for treatment. After the three-stage cylinder B9 stops moving, the electric push rod 17 again moves the L-shaped rod 10 close to the gear 18, facilitating subsequent meshing and connection.
