Description
Technical Field
[0001] This utility model belongs to the technical field of preventing scaling and clogging in mine drainage pumping wells, and specifically relates to an anti-scaling device. Background Technology
[0002] With the rapid development of global industrialization and urbanization, groundwater resources, as an important strategic resource, are receiving increasing attention for their extraction and utilization. However, during the long-term groundwater dewatering (extraction) process in mines, the problem of scaling and clogging in pumping wells has gradually become prominent, becoming a key factor restricting the efficiency and quality of groundwater dewatering (extraction). Scaling and clogging in pumping wells not only affect the amount of groundwater extracted but may also lead to water quality degradation and even environmental and safety problems. Therefore, in-depth research into this issue and the development of effective solutions are of great significance for ensuring mine safety and the sustainable utilization of groundwater resources.
[0003] This utility model provides an anti-scaling device, which aims to solve problems such as poor water flow, well wall damage and pump wear caused by scaling and blockage during the use of water pumps, thereby improving the efficiency of water pumps, extending their service life, and ensuring the stable operation of water pumps and water supply safety. Utility Model Content
[0004] In view of this, the present invention provides an anti-scaling device that can solve problems such as poor water flow, well wall damage and pump wear caused by scaling and blockage during the use of water pumps, thereby improving the efficiency of water pumps, extending their service life, and ensuring the stable operation of water pumps and the safety of water supply.
[0005] This utility model is implemented as follows:
[0006] This utility model provides an anti-scaling device, comprising a wellhead air-filling sealing device, a well drainage pipe, an exhaust pipe, and an anti-scaling agent pipe. The wellhead air-filling sealing device is a cylindrical structure, with its bottom dimension matching the wellhead dimension and its top dimension larger than the wellhead dimension. The change in size is an arc-shaped structure, used to seal the wellhead to prevent external air from entering the well and to prevent the anti-scaling agent from escaping. The well drainage pipe is fixed at the center of the wellhead air-filling sealing device, and is used to discharge sewage. The exhaust pipe and the anti-scaling agent pipe are fixed inside the wellhead air-filling sealing device at a position away from the well drainage pipe. The exhaust pipe is used to exhaust gas from the well into the pumping well, and the anti-scaling agent pipe is used to add anti-scaling agent into the pumping well.
[0007] The technical effects of the anti-scaling device provided by this utility model are as follows: The wellhead air-filling sealing device adopts a cylindrical structure with a bottom size matching the wellhead and a larger top size. The arc-shaped structure ensures a tight seal, preventing external air from entering the well and avoiding the escape of the anti-scaling agent, thereby improving the system's sealing performance.
[0008] The vent pipe is used to remove gas from the well, preventing abnormal pressure caused by gas accumulation. The vent at the top effectively removes gas from the well, while the valve design ensures that the anti-scaling agent does not escape during cleaning, guaranteeing the system's cleaning effectiveness. The vent pipe's position ensures that it does not affect the anti-scaling agent's effectiveness during operation, while also allowing for timely handling of gas in the well and maintaining normal well pressure.
[0009] Based on the above technical solution, the anti-scaling device of this utility model can be further improved as follows:
[0010] The wellhead air-filling and sealing device is made of rubber and has a gas inlet and outlet at the top. The gas inlet and outlet are used to fill the wellhead air-filling and sealing device with air, causing it to expand and seal the pipe opening. The side wall of the wellhead air-filling and sealing device is provided with threads to increase the friction with the wellhead position, so that the wellhead air-filling and sealing device is more firmly fixed at the wellhead position.
[0011] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: using rubber material provides good elasticity and sealing performance; the threaded sidewall increases friction with the wellhead, making it more stable and effectively fixing it in the wellhead position.
[0012] Furthermore, valves are provided on the gas inlet and outlet to close the wellhead gas filling and sealing device, thereby sealing it at the wellhead position to prevent gas leakage.
[0013] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the gas inlet and outlet at the top allow the inside to be filled with gas, causing the device to expand to achieve a better sealing effect, while the valve setting prevents gas leakage and ensures a closed state.
[0014] Furthermore, the wellhead gas filling and sealing device is equipped with monitoring sensors that penetrate deep into the well to monitor the concentration and pressure of the anti-scaling agent inside; the monitoring sensors include a gas concentration sensor and a pressure sensor.
[0015] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: In the use of anti-scaling agent tubes, the configuration of monitoring sensors can monitor the concentration of anti-scaling agent in real time, ensuring accurate control of dosage and effect, and avoiding over- or under-dosing.
[0016] Furthermore, the power cable of the monitoring sensor passes through the inside of the wellhead gas filling and sealing device and extends to the outside of the well to connect with the power source.
[0017] The advantages of adopting the above-mentioned improved scheme are as follows: the sensor extends deep into the well, primarily responsible for monitoring the concentration of the anti-scaling agent and the well pressure, ensuring the normal operation of the system. Connecting to an external power source via cable allows for real-time data feedback, facilitating adjustments by operators.
[0018] Furthermore, the well drainage pipe is connected to the output port of the well drainage pump, which is used to pump out the sewage in the well; after the well drainage pipe extends out of the wellhead air-filling sealing device, it bends to one side, and the curvature of the bend is parabolic, with its focal point coinciding with the output port of the well drainage pump.
[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the main function of the well drainage pipe is to effectively discharge sewage from the well, and its design must ensure unobstructed fluid flow and avoid blockage. After being connected to the well drainage pump, the sewage can be quickly extracted through the pump's action, maintaining the cleanliness of the well environment.
[0020] The parabolic shape design of well drainage pipes helps reduce fluid resistance and ensures pumping efficiency and effectiveness.
[0021] Furthermore, the bottom of the anti-scaling agent tube extends below the water surface inside the well.
[0022] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the anti-scaling agent tube allows the anti-scaling agent to be effectively injected into the well to combat scaling. Its bottom extends below the water surface, helping to ensure uniform dosage distribution and maximize effectiveness.
[0023] Furthermore, the monitoring sensor is inserted deep into the well and placed above the water surface inside the well.
[0024] Furthermore, the exhaust pipe extends into the well, and an exhaust port is provided at its top for discharging gas from the well.
[0025] Furthermore, a valve is provided on the vent hole to prevent gas from escaping when the anti-scaling agent cleans the well, thus affecting the cleaning effect.
[0026] Compared with the prior art, the beneficial effects of the anti-scaling device provided by this utility model are:
[0027] 1. The wellhead air-filling plugging device is mainly used to seal the wellhead to prevent external air from entering the well and to prevent the escape of anti-scaling agent. Its cylindrical structure design ensures that the bottom size matches the wellhead, while the top size is larger than the wellhead, thus achieving a good sealing effect through the arc structure.
[0028] The use of rubber provides excellent elasticity and sealing. The gas inlet and outlet allow the device to be inflated, thus expanding it and firmly sealing the wellhead.
[0029] 2. The main purpose of the well drainage pipe is to effectively discharge sewage from the well. It is connected to the well drainage pump to ensure that sewage can be quickly pumped out, maintaining the cleanliness of the well environment.
[0030] The curved design (parabolic shape) of the drain pipe optimizes fluid flow, making sewage discharge smoother. The focal point coincides with the pump's output port, which helps improve overall efficiency.
[0031] 3. The purpose of the vent pipe is to expel the gas generated inside the well to prevent gas accumulation and potential safety hazards. It is equipped with a vent at the top for effective gas discharge.
[0032] The valve installed at the vent can prevent the anti-scaling agent from escaping into the well during the cleaning process, thus affecting the cleaning effect.
[0033] 4. Anti-scaling agent tubing is used to inject anti-scaling agents into the well to reduce or prevent scale formation. The bottom of the anti-scaling agent tubing extends below the water surface to ensure that the agent is fully mixed and effective.
[0034] A proper layout with other pipelines can ensure the effective distribution of anti-scaling agents and improve the anti-scaling effect.
[0035] 5. The monitoring sensors enable real-time monitoring of critical parameters such as the concentration and pressure of the anti-scaling agent within the well. The combination of gas concentration and pressure sensors provides the necessary data support for the system.
[0036] Power cable: The sensor is connected to an external power source via a cable to ensure a stable power supply and data transmission.
[0037] The various components work together to form a highly efficient anti-scaling device. The wellhead air-sealing device provides sealing and protection, the well drain pipe and vent pipe ensure environmental cleanliness and safety, and the anti-scaling agent pipe and monitoring sensors ensure the effectiveness of the anti-scaling operation. This integrated design not only extends the well's service life but also improves its operational efficiency. Attached Figure Description
