Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and more specifically, to an integrated water purification equipment pulse sludge discharge device. Background Technology

[0002] In urban water supply systems, water treatment plants, as core infrastructure, bear the crucial responsibility of providing safe and stable drinking water to residents, commercial users, and industrial users. Currently, the mainstream water purification process in my country's urban water treatment plants mostly adopts the classic process of "coagulation-sedimentation-filtration-disinfection." Among them, the sedimentation stage is the core step in removing suspended particles and colloidal impurities from the raw water, and its operating efficiency directly determines the load of subsequent filtration processes and the final effluent water quality.

[0003] Integrated water purification equipment is mainly used in urban waterworks. This equipment includes a sedimentation tank and currently primarily employs gravity-based sludge removal, relying on the sludge's own weight to naturally drain through a discharge pipe. This method is slow, has a long cycle, and easily creates a "dead zone" at the bottom of the discharge pipe, leading to long-term sludge accumulation and hardening. Therefore, we propose a pulse sludge removal device for integrated water purification equipment. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an integrated water purification equipment pulse sludge discharge device to solve the current technical problems of slow sludge discharge speed, long cycle, and easy formation of "dead zone" at the bottom of the sludge discharge pipe, which leads to long-term sludge accumulation and hardening.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an integrated water purification equipment pulse sludge discharge device, including a sedimentation tank and a pulse sludge discharge mechanism installed inside the sedimentation tank. The pulse sludge discharge mechanism includes an air inlet pipe located outside the sedimentation tank and a pulse sludge discharge pipe located inside the sedimentation tank. The air inlet pipe includes an air inlet section and a pulse section. An installation plate is provided on the inner wall of the air inlet section. A spring is provided on the installation plate. A piston plate adapted to the size of the air inlet section is provided at the end of the spring. The pulse sludge discharge pipe includes a coarse pipe section, a U-shaped section, a thin pipe section and a sludge discharge section in sequence along the long axis direction. An exhaust pipe is provided at equal intervals on the coarse pipe section.

[0006] Preferably, the pulse section with a variable diameter is located at the end of the air intake section, and the diameter of the pulse section is larger than the diameter of the air intake section.

[0007] Preferably, drainage grooves are provided at equal intervals on the top back of the sedimentation tank, and a sedimentation filter layer is provided inside the sedimentation tank.

[0008] Preferably, positioning rods 9 are symmetrically arranged on the mounting plate. The positioning rods 9 are L-shaped and their ends are connected to the inner wall of the pulse section. Positioning holes are opened on the piston plate, and the positioning rods 9 are densely arranged in the positioning holes.

[0009] Preferably, the U-shaped section, the coarse pipe section, and the sludge discharge section have the same diameter, the U-shaped section connects the coarse pipe section and the fine pipe section, and the U-shaped section is located outside the sedimentation tank.

[0010] Preferably, the exhaust pipe has its opening facing upwards, and the thin tube section is provided with sludge suction pipes at equal intervals. The end of the sludge suction pipe is provided with a flared opening, which faces downwards. The sedimentation filter layer is located between the exhaust pipe and the sludge suction pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model designs a pulse sludge discharge pipe structure. The pulse sludge discharge pipe adopts a variable diameter design of "coarse pipe section - U-shaped section - fine pipe section". The exhaust pipes with equal distances and upward openings on the coarse pipe section can discharge part of the pulse airflow upwards, directly hitting the sedimentation filter layer located above the exhaust pipe. The backflow of the airflow can loosen the sludge attached to the surface of the filter layer, preventing sludge from clogging the filter layer pores and accumulating and hardening, thus ensuring the filtration performance of the sedimentation filter layer. When the airflow flows through the coarse pipe section and enters the fine pipe section, the venturi effect generated by the narrowing of the pipe diameter creates a negative pressure in the fine pipe section. Combined with the sludge suction pipe and the downward-facing flared end, it can efficiently adsorb the sludge on the sedimentation filter layer. The flared end expands the adsorption range, ensuring that there are no dead corners in the sedimentation tank for sludge cleaning, ensuring sludge discharge efficiency, simple operation, and low energy consumption. It is suitable for the operation needs of integrated water purification equipment in urban waterworks and other scenarios, solving the current problems of slow sludge discharge speed, long cycle, and easy formation of "dead zone" at the bottom of the sludge discharge pipe, which leads to long-term accumulation and hardening of some sludge.

[0012] 2. This utility model also designs an air intake pipe structure. The air intake part of the air intake pipe works in conjunction with the pulse part. By using the difference in pipe diameter, a pressure change is generated with the help of a spring and a piston plate to form a high-intensity pulsed airflow. Compared with the direct current airflow, the impact force of this pulsed airflow is greater, which can quickly promote the fluid flow in the pulsed sludge discharge pipe. Combined with the exhaust pipe impacting the sedimentation filter layer, it avoids the risk of sludge accumulating and caking. In addition, the spring drives the piston plate to automatically reset and continuously supplies air to the air intake pipe, realizing the periodic output of the pulsed airflow. No additional power control is required, which improves the stability and reliability of the mechanism operation. Attached Figure Description

Detailed Implementation

[0015] like Figures 1 to 4 As shown, the present invention relates to an integrated water purification equipment pulse sludge discharge device, including a sedimentation tank 101 and a pulse sludge discharge mechanism 200 disposed within the sedimentation tank 101. The pulse sludge discharge mechanism 200 includes an air inlet pipe 201 located outside the sedimentation tank 101 and a pulse sludge discharge pipe 202 located inside the sedimentation tank 101. The air inlet pipe 201 includes an air inlet section 2011 and a pulse section 2012. An installation plate 206 is disposed on the inner wall of the air inlet section 2011. A spring 207 is disposed on the installation plate 206. A piston plate 208 adapted to the size of the air inlet section 2011 is disposed at the end of the spring 207. The pulse sludge discharge pipe 202 includes a coarse pipe section 2021, a U-shaped section 2022, a thin pipe section 2023 and a sludge discharge section 2024 in sequence along the long axis direction. An exhaust pipe 203 is disposed at equal intervals on the coarse pipe section 2021. This utility model generates a high-intensity pulsed airflow through the air inlet pipe 201 structure, and the pulsed sludge discharge pipe 202 with its variable diameter design, combined with the Venturi effect and siphon principle, efficiently cleans sludge and can also backwash the sedimentation filter layer 103 to prevent clogging. It is easy to operate, has low energy consumption, and is stable in operation, making it suitable for the needs of urban waterworks and other scenarios.

[0016] Specifically, the pulse section 2012 has a variable diameter at the end of the air inlet section 2011, with the diameter of the pulse section 2012 being larger than that of the air inlet section 2011. This difference in pipe diameter utilizes fluid dynamics principles; when the airflow enters the larger-diameter pulse section 2012 from the smaller-diameter air inlet section 2011, a pressure surge occurs, further enhancing the pulse effect and enabling the airflow to more efficiently drive the water flow within the sludge discharge pipe.

[0017] Furthermore, drainage channels 102 are equidistantly provided at the top back of the sedimentation tank 101, and a sedimentation filter layer 103 is provided inside the sedimentation tank 101. The equidistant design of the drainage channels 102 ensures that the supernatant in the sedimentation tank 101 is discharged evenly. The sedimentation filter layer 103 divides the sedimentation tank 101 into upper and lower spaces, which facilitates the installation of the pulse sludge discharge mechanism 200. Secondly, the sedimentation filter layer 103 is used for sedimentation to prevent sediment from entering the lower pipe and to prevent sludge from accumulating and hardening.

[0018] It is worth noting that positioning rods 209 are symmetrically arranged on the mounting plate 206. The positioning rods 209 are L-shaped, and their ends are connected to the inner wall of the pulse section 2012. Positioning holes are opened on the piston plate 208, and the positioning rods 209 are densely arranged in the positioning holes. The L-shaped positioning rods 209 achieve stable support by being fixed at both ends. Their cooperation with the positioning holes of the piston plate 208 can strictly limit the movement trajectory of the piston plate 208, prevent the piston plate 208 from shifting or tilting under the action of airflow, and ensure that the piston plate 208 is always in close contact with the inner wall of the air intake section 2011, thus ensuring the airflow sealing effect.

[0019] It is worth noting that the U-shaped section 2022, the coarse pipe section 2021, and the sludge discharge section 2024 have the same pipe diameter. The U-shaped section 2022 connects the coarse pipe section 2021 and the fine pipe section 2023, and is located outside the sedimentation tank 101. The coarse pipe section 2021 and the fine pipe section 2023 have a large difference in pipe diameter. During the airflow process, a Venturi effect will occur. When the airflow passes through the coarse pipe section 2021, the pressure behind it increases due to the fine pipe section 2023. This causes part of the airflow to be discharged from the exhaust pipe 203 and directly rush to the sedimentation filter layer 103. Under the backwashing action, it can prevent sludge from accumulating and caking on the sedimentation filter layer 103, and at the same time, it can cooperate with the subsequent sludge discharge work.

[0020] It is worth noting that the exhaust pipe 203 is positioned with its opening facing upwards, and sludge suction pipes 204 are equidistantly arranged on the narrow tube section 2023. The sludge suction pipes 204 have a bell-shaped opening 205 at their ends, which faces downwards. The sedimentation filter layer 103 is located between the exhaust pipe 203 and the sludge suction pipes 204. When the airflow passes through the coarse tube section 2021, some airflow also flows along the long axis of the pulse sludge discharge pipe 202. When the airflow enters the narrow tube section 2023, it continues to flow forward, thus generating a siphon effect. Through the cooperation of the sludge suction pipes 204 and the bell-shaped opening 205, the sludge and sand on the sedimentation filter layer 103 can be extracted and discharged from the sludge discharge section 2024.

[0021] Working Principle: This embodiment provides an integrated water purification equipment pulse sludge removal device. In use, compressed gas is continuously supplied to the air inlet 2011 of the air inlet pipe 201 through an external air source. After entering the air inlet 2011, the gas exerts pressure on the piston plate 208. As the gas pressure gradually increases, when the pressure overcomes the elastic force of the spring 207, the piston plate 208 moves along the guide of the positioning rod 209 towards the pulse section 2012. When the piston plate 208 enters the pulse section 2012, the gas in the air inlet 2011 rapidly enters the pulse section. In the pulse section 2012, because the diameter of the pulse section 2012 is larger than that of the inlet section 2011, the gas will experience a pressure change within the pulse section 2012, forming a stronger pulsed airflow. This pulsed airflow then enters the coarse section 2021 of the pulsed sludge discharge pipe 202. A portion of the pulsed airflow entering the coarse section 2021 is discharged through the equally spaced, upward-facing exhaust pipes 203. The discharged airflow directly impacts the sedimentation filter layer 103 located above the exhaust pipe 203, providing a backflushing effect on the sludge adhering to the sedimentation filter layer 103, effectively preventing sludge from settling. Silt and tar form on the surface of the filter layer 103. Simultaneously, another portion of the pulsed airflow continues along the coarse tube 2021 towards the U-shaped section 2022. After passing through the U-shaped section 2022, it enters the fine tube 2023. Because the diameter of the fine tube 2023 is smaller than that of the coarse tube 2021, the airflow velocity increases within the fine tube 2023. Based on the Venturi effect and the siphon principle, a negative pressure is formed within the fine tube 2023. This negative pressure is then removed through the sludge suction pipes 204, which are equidistantly positioned on the fine tube 2023, and the downward-facing bell-shaped openings 205 at the ends of the sludge suction pipes 204. The sludge and sediment loosened by backflushing on the filter layer 103 are drawn into the capillary section 2023. Finally, the sludge and sediment drawn into the capillary section 2023 are mixed with the airflow and continue to flow along the capillary section 2023. They are then discharged from the device through the sludge discharge section 2024, completing the pulse sludge discharge process. During the sludge discharge process, when the gas pressure in the air inlet section 2011 decreases, the elastic force of the spring 207 will push the piston plate 208 to reset and re-seal the air inlet section 2011, waiting for the next gas pressure accumulation. This cycle repeats to achieve continuous and efficient pulse sludge discharge operation.
