Description

Technical Field

[0001] This application relates to the field of deodorization of wastewater treatment ponds, and in particular to a deodorization device for chemical wastewater treatment ponds. Background Technology

[0002] In existing technologies, deodorization of chemical wastewater treatment ponds is often achieved by adding deodorizing particles to the wastewater. The deodorizing particles in existing technologies are mostly composite potassium persulfate particles, which achieve deodorization by chemically neutralizing malodorous substances such as hydrogen sulfide and ammonia in the wastewater. The corresponding deodorization device usually includes a storage tank, a dosing mechanism, and a power unit. The dosing mechanism is mostly a screw conveyor or a quantitative dosing valve, which requires an additional power source such as a motor or pump to drive the deodorizing particles in the storage tank to the wastewater. Some devices also need to be equipped with a separate stirring mechanism to mix the particles with the wastewater.

[0003] The aforementioned existing technologies have significant problems: the continuous operation of power sources such as motors and pumps consumes a large amount of electrical energy, increasing daily operating costs; at the same time, the power equipment and supporting circuits have high maintenance requirements and are prone to failure due to the corrosive environment of chemical wastewater, which not only increases maintenance costs but may also cause deodorization interruption due to equipment shutdown, affecting the treatment effect. Utility Model Content

[0004] In order to improve the problem that existing deodorization devices rely on additional power sources such as motors and pumps, resulting in high energy consumption and high operating costs, this application provides a deodorization device for chemical wastewater treatment ponds.

[0005] The deodorization device for a chemical wastewater treatment pond provided in this application adopts the following technical solution: A deodorization device for a chemical wastewater treatment pond includes an inlet pipe with a U-shaped channel inside. The first end of the U-shaped channel has an inlet, and the last end of the U-shaped channel has an outlet lower than the inlet. The middle of the U-shaped channel is connected to a spreading chamber, the top of which is higher than the inlet. A storage box for holding deodorizing particles is installed at the top of the spreading chamber. A water wheel is rotatably connected to the lower part of the spreading chamber, and the lower part of the water wheel is located in a U-shaped channel. A discharge roller is rotatably connected to the lower part of the storage box, and a transmission box for connecting the water wheel and the discharge roller is installed in the water inlet pipe.

[0006] By adopting the above technical solution, chemical wastewater flows into the U-shaped channel from the inlet. Because the outlet is lower than the inlet, water flow is formed, which drives the water wheel in the U-shaped channel to rotate. The water wheel drives the discharge roller below the storage box to rotate through the transmission box, so that the deodorizing particles in the storage box are discharged. At the same time, the water wheel stirs and mixes the deodorizing particles and wastewater. The top of the spreading chamber is higher than the inlet to avoid wastewater overflow and prolong the residence time of wastewater in the inlet pipe. This solves the problem that existing deodorization devices rely on additional power sources such as motors and pumps, resulting in high energy consumption and high operating costs.

[0007] Preferably, the storage box has a rectangular inner cavity, a V-shaped contraction cavity and a semi-cylindrical cavity arranged sequentially from top to bottom. The discharge roller is rotatably connected to the semi-cylindrical cavity, and the lower outer wall of the discharge roller is in contact with the inner wall of the semi-cylindrical cavity. A strip-shaped discharge port is provided below the semi-cylindrical cavity, and a sealing cover is provided above the rectangular inner cavity in the storage box.

[0008] By adopting the above technical solution, the deodorizing particles in the storage box enter the semi-cylindrical cavity through the rectangular inner cavity and the V-shaped contraction cavity. The discharge roller contacts the inner wall of the semi-cylindrical cavity and discharges the particles from the strip discharge port when it rotates. The V-shaped contraction cavity guides the particles to gather, and the sealing cover is used to protect the deodorizing particles in the storage box.

[0009] Preferably, the inner width of the spreading chamber is the same as the diameter of the water wheel, and the water wheel includes a first straight roller and several water plates vertically connected to the outer wall of the first straight roller. The two ends of the first straight roller are rotatably connected to the inner wall of the U-shaped channel.

[0010] By adopting the above technical solution, the width of the spreading chamber is matched with the diameter of the water wheel, ensuring stable rotation of the water wheel. The water flow impacts the water plate on the first straight roller, driving the first straight roller to rotate on the inner wall of the U-shaped channel, thus efficiently acquiring the kinetic energy of the water flow.

[0011] Preferably, the discharge roller includes a second straight roller and a plurality of material distribution plates vertically connected to the outer wall of the second straight roller, and the transmission box is connected between the first straight roller and the second straight roller.

[0012] By adopting the above technical solution, the transmission box transmits the power of the first straight roller to the second straight roller. When the second straight roller rotates, the material distribution plate separates and carries out the deodorizing particles in the storage box, achieving uniform discharge.

[0013] Preferably, the transmission box includes a first synchronous pulley connected to the second straight roller, a second synchronous pulley connected to the first straight roller, and a synchronous belt surrounding the outer rings of the first and second synchronous pulleys.

[0014] By adopting the above technical solution, the first synchronous pulley rotates with the second straight roller, the second synchronous pulley rotates with the first straight roller, and the synchronous belt connects the first synchronous pulley and the second synchronous pulley, so as to realize the synchronous transmission between the water wheel and the discharge roller and stably transmit kinetic energy.

[0015] Preferably, the transmission box further includes a first waterproof box and a second waterproof box that are sealed together. The first waterproof box is provided with a first round hole and a second round hole. One side of the first synchronous pulley rotates through the first round hole, and one side of the second synchronous pulley rotates through the second round hole.

[0016] By adopting the above technical solution, the first waterproof box and the second waterproof box are sealed together, and the first and second round holes allow the first and second synchronous pulleys to pass through, which ensures transmission and prevents sewage from entering the transmission box.

[0017] Preferably, a plurality of material distribution blocks are installed at equal intervals above the semi-cylindrical cavity in the storage box, and the cross-section of the material distribution blocks is a triangle with the apex pointing upwards.

[0018] By adopting the above technical solution, the triangular-section dividing block divides the deodorizing particles into equal segments above the semi-cylindrical cavity, avoiding excessive particle accumulation that could press down the discharge roller, reducing the pressure between the discharge roller and the particles, and preventing blockage.

[0019] Preferably, one side of the spreading chamber is connected to a connecting cavity for installing the transmission box, and a cover plate is installed above the connecting cavity.

[0020] By adopting the above technical solution, the connecting cavity provides installation space for the transmission box, and the cover plate covers the top of the connecting cavity, which facilitates later opening and reduces the spread of odor.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. This application requires no additional power source such as a motor or pump. It utilizes the water flow formed by the water level difference between the inlet and outlet of the U-shaped channel to drive the water wheel to rotate. The automatic dispensing of deodorizing particles is achieved through the linkage of the transmission box and the discharge roller. This fundamentally solves the problems of high energy consumption and high operation and maintenance costs of existing technologies. Moreover, the water wheel rotates and simultaneously stirs the sewage and deodorizing particles, eliminating the need for a separate stirring mechanism, which simplifies the structure. Furthermore, the larger the sewage flow, the faster the water wheel speed, and the amount of chemicals dispensed by the discharge roller increases accordingly, achieving dynamic matching between the amount of chemicals dispensed and the amount of sewage, thus improving the stability of deodorization.

[0022] 2. In this application, the diameter of the water wheel is the same as the width of the spreading chamber, and the central axis of the water wheel is perpendicular to the water flow direction of the U-shaped channel. This ensures that the water flow impacts the water plate evenly, making the water wheel rotate stably. It also allows the water wheel to fully agitate the falling deodorizing particles in the spreading chamber. In addition, the U-shaped channel extends the sewage retention time, allowing the particles and sewage to achieve more thorough contact and mixing.

[0023] 3. In this application, the discharging roller's distribution plate is in close contact with the inner wall of the semi-cylindrical cavity. When rotating, a fixed volume material cavity can be formed between every two adjacent distribution plates, accurately accommodating a quantitative amount of deodorizing particles and carrying them to the strip-shaped discharge port. This structure ensures that the dosage is only related to the water wheel speed and will not result in excessive or insufficient dosage due to changes in the remaining particle amount in the storage tank.

[0026] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0027] This application discloses a deodorization device for a chemical wastewater treatment pond.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 6A deodorization device for a chemical wastewater treatment pond includes an inlet pipe 1 for supplying water to the wastewater treatment pond. The inlet pipe 1 has a U-shaped channel with one end higher than the other. The two ends of the U-shaped channel are respectively provided with an inlet 11 and an outlet 12. The outlet 12 is lower than the inlet 11. The middle of the U-shaped channel is connected upward to a spreading chamber 14 that is higher than the inlet 11. The spreading chamber 14 is located between the outlet 12 and the inlet 11. A water wheel 4 with the same diameter as the inner width of the spreading chamber 14 is rotatably connected below the spreading chamber 14. The water wheel 4 is arranged horizontally, and the central axis of the water wheel 4 is perpendicular to the water flow direction of the U-shaped channel. The lower part of the water wheel 4 is located in the U-shaped channel, and the upper part of the water wheel 4 is located in the spreading chamber 14. The water wheel 4 includes a first straight roller 41 rotatably connected to the inner wall of the U-shaped channel and several water plates 42. The several water plates 42 are alternately and vertically fixedly connected to the outer wall of the first straight roller 41. The inlet 11 of the inlet pipe 1 needs to continuously supply chemical wastewater that meets the rated flow and initial head required for the design conditions, so as to ensure that the water flow has the basic power to drive the water wheel. Because the U-shaped channel in the inlet pipe 1 has a water level difference due to the inlet 11 being higher than the outlet 12, the chemical wastewater generates a stable water flow when it flows through. The water flow impacts the water wheel 4 in the U-shaped channel, and the water wheel 4 is driven to rotate around the axis by the water plates 42 interlaced on the outer wall of the first straight roller 41. The axis is perpendicular to the water flow direction to ensure uniform force. The diameter of the water wheel 4 is the same as the width of the spreading chamber 14. Its upper part is located in the spreading chamber 14 and its lower part is located in the U-shaped channel. This design can avoid the wastewater in the spreading chamber 14 from affecting the rotation of the water wheel 4, ensuring that the water flow effectively drives the rotation and providing space for subsequent mixing of deodorizing particles and wastewater.

[0029] Reference Figure 3 , Figure 4 , Figure 8 A storage box 2 is fixedly installed at the top of the spreading chamber 14. The storage box 2 is used to hold deodorizing particles. The storage box 2 is provided with a rectangular inner cavity 22, a V-shaped contraction cavity 23, and a semi-cylindrical cavity 24. The rectangular inner cavity 22, the V-shaped contraction cavity 23, and the semi-cylindrical cavity 24 are connected to each other from top to bottom. A strip-shaped discharge port 26 is provided directly below the semi-cylindrical cavity 24. The inner width of the strip-shaped discharge port 26 is larger than the diameter of the deodorizing particles. The upper part of the rectangular inner cavity 22 in the storage box 2... The storage tank 2 is equipped with a sealing cover 21 for covering the deodorizing particles inside. Several material distribution blocks 25 with triangular cross-sections pointing upwards are installed at equal intervals above the semi-cylindrical cavity 24 in the storage tank 2. A connecting cavity 15 is connected to one side of the spreading chamber 14. The connecting cavity 15 is used to install the transmission box 3. A cover plate 13 is installed above the connecting cavity 15 and is in contact with the outer wall of the storage tank 2 and the top of the water inlet pipe 1. A discharge roller 5 is horizontally connected below the storage tank 2. The storage bin 2 stores a large number of deodorizing particles through the rectangular inner cavity 22. The V-shaped shrinkage cavity 23 guides the particles to gather downwards. The semi-cylindrical cavity 24 provides a suitable space for the discharge roller 5. The width of the strip discharge port 26 is greater than the particle diameter to ensure that the particles are discharged smoothly. The sealing cover 21 can prevent the particles from getting damp or odors from overflowing, and it is easy to open and replenish the particles. The triangular dividing block 25 above the semi-cylindrical cavity 24 can evenly divide the particles to avoid accumulation and blockage. The connecting cavity 15 provides an installation position for the transmission box 3. The cover plate 13 seals the connecting cavity 15.

[0030] Reference Figure 3 , Figure 4 , Figure 7 The discharge roller 5 is rotatably connected to the semi-cylindrical cavity 24. The discharge roller 5 includes a second straight roller 51 and several distribution plates 52 vertically connected to the outer wall of the second straight roller 51. A rotating hole 27 is provided on one side of the lower part of the storage box 2, through which the second straight roller 51 is rotatably connected. One end of the second straight roller 51 passes through the rotating hole 27, and the outer wall of the distribution plate 52 below the discharge roller 5 is in contact with the inner wall of the semi-cylindrical cavity 24. The transmission box 3 is connected between the first straight roller 41 and the second straight roller 51. The material roller 5 rotates within the semi-cylindrical cavity 24 via the second straight roller 51. The material distribution plate 52 on the outer wall rotates with it, which can separate the deodorizing particles in the semi-cylindrical cavity 24 and carry them to the strip discharge port 26. The material distribution plate 52 contacts the inner wall of the semi-cylindrical cavity 24, which not only prevents the particles from leaking out, but also ensures that a certain amount of particles are carried out with each rotation. One end of the second straight roller 51 passes through the rotating hole 27 and is connected to the transmission box 3, so as to realize linkage with the first straight roller 41 of the water wheel 4, so that the discharge action is synchronized with the water flow drive.

[0031] Reference Figure 5 The water inlet pipe 1 is equipped with a transmission box 3 for connecting the water wheel 4 and the discharge roller 5. The transmission box 3 includes a first synchronous pulley 33, a second synchronous pulley 34, a synchronous belt 35, a first waterproof box 31, and a second waterproof box 32. The first synchronous pulley 33 is fixedly connected to the second straight roller 51, and the second synchronous pulley 34 is fixedly connected to the first straight roller 41. The inner ring of the synchronous belt 35 is connected around the outer ring of the first synchronous pulley 33 and the second synchronous pulley 34 respectively. The first waterproof box 31 and the second waterproof box 32 are sealed together by a sealing gasket and bolts. The upper and lower ends of the first waterproof box 31 are respectively provided with a first round hole 36 and a second round hole 37. One side of the first synchronous pulley 33 rotates through the first round hole 36 through a bearing, and one side of the second synchronous pulley 34 rotates through the second round hole 37 through a bearing. The transmission box 3, through the cooperation of the first synchronous pulley 33, the second synchronous pulley 34 and the synchronous belt 35, transmits the rotational kinetic energy of the first straight roller 41 in the water turbine 4 to the second straight roller 51 in the discharge roller 5, so as to realize the synchronous operation of the water turbine 4 and the discharge roller 5. The first waterproof box 31 and the second waterproof box 32 are sealed by sealing gaskets and bolts to prevent sewage from entering the transmission box 3 and affecting the transmission components. The bearings at the first round hole 36 and the second round hole 37 not only ensure that the synchronous pulleys pass through smoothly, but also reduce rotational friction, so as to ensure stable and efficient transmission.

[0032] In this embodiment, during the daily reception and pretreatment of wastewater in the chemical wastewater treatment pond, the inlet 11 of the inlet pipe 1 needs to continuously receive chemical wastewater that meets the rated flow and initial head required by the design conditions. This ensures that the water flow has the basic power to drive the water turbine. Alternatively, the installation elevation of the spreading chamber 14 and the high-level inlet 11 can be simultaneously raised to increase the elevation difference between the inlet and the water turbine 4, allowing sufficient hydraulic potential energy to be generated when the wastewater flows through the U-shaped channel. The chemical wastewater flows into the U-shaped channel through the inlet 11 of the inlet pipe 1. Because the outlet 12 of the U-shaped channel is lower than the inlet 11, a natural water level difference is formed. When the wastewater flows, it impacts the water turbine 4 located in the U-shaped channel, causing the first straight roller 41 and the water plate 42 on the outer wall of the water turbine 4 to rotate. As the water turbine 4 rotates, it drives the transmission... The linkage between the first synchronous wheel 33, the second synchronous wheel 34 and the synchronous belt 35 in the box 3 drives the discharge roller 5 in the semi-cylindrical cavity 24 below the storage box 2 to rotate. The second straight roller 51 and the distribution plate 52 of the discharge roller 5 discharge the deodorizing particles stored in the storage box 2 through the rectangular inner cavity 22, gathered in the V-shaped shrinkage cavity 23 and evenly separated by the distribution block 25, and discharge them quantitatively from the strip discharge port 26. After the discharged deodorizing particles fall into the spreading chamber 14, they are synchronously stirred by the rotating water wheel 4 and fully mixed with the sewage in the U-shaped channel. After extending the mixing contact time, they are discharged into the sewage treatment tank from the outlet 12. The whole process does not require an additional motor or other power source. It can complete the dosing and mixing by relying only on the kinetic energy of the sewage itself, realizing the efficient deodorization pretreatment of chemical sewage and laying the foundation for subsequent sewage treatment tank operations.
