Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a precise metering device for defluorinating agents. Background Technology

[0002] Excessive fluoride ion emissions during industrial wastewater treatment pose a serious threat to the environment and human health. High concentrations of fluoride ions can pollute water bodies, soil, and groundwater resources, disrupt ecological balance, and affect the normal growth and reproduction of plants and animals. For aquatic organisms, fluorides may be toxic, leading to a decline in biodiversity. Therefore, strictly controlling the concentration of fluoride ions in industrial wastewater and employing efficient wastewater treatment technologies are crucial for protecting the ecological environment and safeguarding human health.

[0003] Chinese Patent Publication No. CN219507734U discloses a wastewater defluorination device, which includes a first defluorination tank and a second defluorination tank disposed above the first defluorination tank. The first and second defluorination tanks are connected by a connecting pipe, and a filter assembly is installed inside the second defluorination tank. This utility model uses the above-mentioned wastewater defluorination device, which allows wastewater to undergo two-stage defluorination, resulting in good defluorination efficiency. The device also has disinfection and deodorization functions.

[0004] Regarding the aforementioned technologies, this device has some shortcomings. In practical use, the method of adding defluorinating agent to the first defluorination tank via the inlet pipe is too simple, making precise metering difficult. For example, users may not be able to control the exact amount of defluorinating agent added, which could result in insufficient dosage, failing to achieve the desired defluorination effect, or excessive dosage, increasing operating costs. Therefore, this simple addition method fails to meet the requirements for efficient and precise defluorination. Thus, it is necessary to provide a precise defluorinating agent metering device to solve the above-mentioned technical problems. Utility Model Content

[0030] A precise metering device for defluorinating agent, comprising:

[0031] A substrate 1 has a wastewater treatment tank 2 fixedly mounted on its top. A storage tank 3 is located on one side of the wastewater treatment tank 2 on the top of the substrate 1. Several support legs 5 are fixedly mounted on the bottom of the storage tank 3, and the support legs 5 are in contact with the top of the substrate 1. An output pipe 6 is fixedly inserted into the bottom of the storage tank 3. A metering pump 7 is fixedly mounted on the outer surface of the storage tank 3 near the wastewater treatment tank 2, and one end of the output pipe 6 is fixedly connected to the input end of the metering pump 7.

[0032] The output end of the metering pump 7 is fixedly connected to the addition pipe 10, and one end of the addition pipe 10 is connected to the chemical addition pipe on the sewage treatment tank 2. The top of the storage tank 3 is provided with a cover plate 4, and a liquid addition pipe 11 is fixedly installed on one side of the top of the cover plate 4.

[0033] A sampling tube 14 is fixedly installed at the bottom of the storage tank 3 on one side of the output pipe 6, and a valve is provided on the sampling tube 14. A controller 8 is fixedly installed on the front of the outer surface of the storage tank 3. The defluorinating agent inside the storage tank 3 is sampled through the sampling tube 14 to facilitate monitoring of the concentration of the defluorinating agent inside the storage tank 3 and to ensure the effectiveness of the defluorinating agent.

[0034] A pressure relief pipe 13 is fixedly installed on the other side of the top of the cover plate 4, and the pressure relief pipe 13 is connected to the bottom of the cover plate 4. A pressure relief hole 21 is opened on the outer wall of the pressure relief pipe 13, and the pressure relief hole 21 is located above the top of the cover plate 4. A sealing plug 22 is slidably installed inside the pressure relief pipe 13. A spring 20 is fixedly connected between the top of the sealing plug 22 and the top of the inner wall of the pressure relief pipe 13. An annular locking member 23 is fixedly installed at the bottom inside the pressure relief pipe 13. The annular locking member 23 can limit the vertical position of the sealing plug 22 to prevent the sealing plug 22 from falling off from the bottom opening of the pressure relief pipe 13 under the elastic action of the spring 20.

[0035] In one embodiment, a motor 12 is fixedly installed on the top of the cover plate 4, and the driving end of the motor 12 passes through the top of the cover plate 4 and extends to the bottom of the cover plate 4. A vertical stirring shaft 16 is fixedly installed on the driving end of the motor 12, and a plurality of horizontal stirring rollers 17 are fixedly installed on the outer wall of the vertical stirring shaft 16.

[0036] In one preferred embodiment, an electric heating rod 18 is fixedly installed at the bottom of the sewage treatment tank 2 on one side of the transverse stirring roller 17, and a temperature sensor 15 is fixedly installed inside the storage tank 3.

[0037] In one embodiment, a transparent glass 9 is fixedly embedded on the outer surface of the storage tank 3 to facilitate observation of the amount of defluorinating agent stored inside the storage tank 3 so that it can be added in a timely manner. The inner wall of the storage tank 3 is provided with an anti-corrosion coating 19 to improve the durability of the device and reduce maintenance costs.

[0038] In one preferred embodiment, the cover plate 4 is fixedly installed on the top of the storage tank 3 by several bolts. The connection between the cover plate 4 and the storage tank 3 is stepped. A sealing gasket is provided at the connection between the cover plate 4 and the storage tank 3, which realizes the detachability of the cover plate 4, making it convenient to clean the inside of the storage tank 3 and to inspect and maintain its internal mechanical parts, thereby improving the use effect of the storage tank 3.

[0039] The working principle of this utility model is as follows: The entire device is controlled by the controller 8. Since the device matched with the controller 8 is a common device and belongs to the existing common knowledge technology, its electrical connection relationship and specific circuit structure will not be described in detail here. The specific structure of the sewage treatment tank 2 can refer to the existing technology, which can be easily implemented by those skilled in the art. In the process of sewage treatment, when the sewage needs to be defluorinated when it is discharged into the sewage treatment tank 2, a certain amount of defluorinating agent will be injected into the storage tank 3 in advance through the liquid addition pipe 11. During the process of adding defluorinating agent, the metering pump 7 is controlled to start working. The metering pump 7 will extract the defluorinating agent located in the storage tank 3 through the output pipe 6 and input it into the addition pipe 10. Then, it will be input into the sewage treatment tank 2 through the addition pipe 10 to react with the sewage. During the process of adding defluorinating agent, the metering pump 7 can accurately control the flow rate of the defluorinating agent input into the sewage treatment tank 2 and monitor it in real time, thereby ensuring that the amount of defluorinating agent added is just right. This precise delivery method effectively prevents the addition of too much or too little defluorinating agent, thereby optimizing defluorination efficiency, meeting the needs of efficient and precise wastewater treatment, improving work efficiency, and ensuring the stability and reliability of the treatment process.

[0040] While the defluorinating agent is stored in storage tank 3, the motor 12 can be started at regular intervals. The drive end of the motor 12 drives the vertical stirring shaft 16 to rotate, and the rotation of the vertical stirring shaft 16 drives the horizontal stirring roller 17 to rotate. The rotation of the horizontal stirring roller 17 will stir the defluorinating agent inside the storage tank 3, prevent the defluorinating agent from settling, ensure that the defluorinating agent is evenly mixed, prevent sedimentation and stratification, and effectively guarantee the use effect of the defluorinating agent.

[0041] During the storage of the defluorinating agent in storage tank 3, if the internal pressure of storage tank 3 becomes too high, it will cause the sealing plug 22 inside the pressure relief pipe 13 to move upward. The sealing plug 22 will compress the spring 20. When the sealing plug 22 moves above the pressure relief hole 21, the internal pressure of storage tank 3 will be connected to the outside through the pressure relief pipe 13 and the pressure relief hole 21 to relieve pressure. When the internal pressure of storage tank 3 returns to normal, the sealing plug 22 will reset under the elastic action of the spring 20, so that the device has an automatic pressure relief function. When the pressure inside storage tank 3 is too high, it will automatically relieve pressure to prevent the tank from being damaged due to excessive pressure, improve the safety of the device, and prevent accidents.

[0042] Temperature sensor 15 can monitor the temperature of the defluorinating agent stored inside storage tank 3. When the temperature is too low, the defluorinating agent can be heated by electric heating rod 18 to maintain the temperature of the defluorinating agent in storage tank 3 within a suitable range, prevent the defluorinating agent from becoming ineffective or precipitating due to temperature changes, extend the shelf life of the defluorinating agent, and ensure the treatment effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
