Description
Technical Field
[0001] This utility model relates to the field of sedimentation tank technology, and in particular to a double-trough bridge-type sand suction device for sedimentation tanks. Background Technology
[0002] A sedimentation tank is a water treatment or hydraulic engineering facility that uses the principle of gravity sedimentation to separate and remove solid particles such as mud, sand, and gravel from water flow. Its core functions are "sand settling and silt reduction, water purification, and equipment protection". It is widely used in water supply treatment, sewage treatment, water conservancy projects, agricultural irrigation, mine drainage, and landscape engineering.
[0003] Traditional sand suction methods are limited in their application to loose sand particles. They are often ineffective at adsorbing clumps of sand that have adhered to the bottom of the pool due to moisture absorption and gravity compaction, resulting in the long-term retention of these stubborn sand particles. Over time, the residual sand accumulates, affecting not only the normal operation of the equipment but also potentially causing blockages in the pool and increasing the difficulty of subsequent cleaning. Utility Model Content

The compression spring is located outside the movable rod, and the top end of each compression spring is fixedly connected to the inside of the top end of the movable frame.
[0008] In a preferred embodiment, two air pumps are provided above the support plate. Each air pump has an air blowing pipe fixedly connected to its blowing end. The bottom end of each air blowing pipe is fixedly connected to a dispersing pipe, and the dispersing end of each dispersing pipe is fixedly connected to the outside of the air blowing head.
[0009] In a preferred embodiment, sand accumulation tanks are fixedly connected to both sides of the dual-sand tank, and sand discharge pipes are installed above the sand accumulation tanks.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] The present invention discloses a double-channel bridge-type sand suction device for sedimentation tanks, which is mainly used in scenarios where traditional sand suction methods can only remove loose sand particles and are difficult to handle stubborn sand adhering to the bottom of the tank, resulting in incomplete sand cleaning, low efficiency, and the need for frequent repeated sand suction.
[0021] Reference Figures 1-5 A double-trough bridge-type sand suction device for a sedimentation tank is disclosed. The top of the double-trough sand tank 1 is fixedly connected to two guardrails 2. Two support plates 3 are fixedly connected between opposite sides of the guardrails 2. The interior of the double-trough sand tank 1 is provided with two sand suction vertical pipes 10. The outer side of each sand suction vertical pipe 10 is provided with an auxiliary sand suction component 12. The sand suction vertical pipe 10 is located below the support plate 3. The auxiliary sand suction component 12 includes a movable frame 1205. The interior of the movable frame 1205 is provided with two vibrators 1208. Multiple air blowing heads 1209 are provided on both sides of the movable frame 1205. The top of the movable frame 1205 is provided with a round hole, and the sand suction vertical pipe 10 is movably connected to the interior of the round hole.
[0022] Reference Figures 1-5 In a preferred embodiment, the support plate 3 is provided with two motor frames 1201, and each motor frame 1201 is fixedly connected to a drive motor 1202. The power output shafts of the drive motors 1202 are connected to a rotating shaft 1203 through a coupling. A pulling rope 1204 is wound around the outside of the rotating shaft 1203, and the bottom end of the pulling rope 1204 is fixedly connected to the top of the movable frame 1205.
[0023] In this design, the movable frame 1205 has symmetrical holes, and movable rods 1206 are movably connected inside each hole. The bottom end of each movable rod 1206 is fixedly connected to the top end of the vibrator 1208. A compression spring 1207 is fixedly connected to the top end of each vibrator 1208, and the compression spring 1207 is located outside the movable rod 1206. The top end of each compression spring 1207 is fixedly connected to the inside of the top end of the movable frame 1205.
[0024] In this scheme, two air pumps 1212 are installed above the support plate 3. The blowing end of each air pump 1212 is fixedly connected to an air blowing pipe 1211. The bottom end of each air blowing pipe 1211 is fixedly connected to a dispersing pipe 1210. The dispersing end of each dispersing pipe 1210 is fixedly connected to the outside of the air blowing head 1209.
[0025] In the auxiliary sand suction assembly 12, the vibrator 1208 can shake apart the clumps of sand adhering to the bottom of the pool, avoiding the problem that traditional sand suction can only suck away loose sand and leave stubborn sand behind; at the same time, the air blowing head 1209 uses directional airflow to gather the shaken sand particles toward the sand suction head 11, allowing the sand suction head 11 to suck away more sand particles at once, greatly improving the thoroughness and efficiency of sand suction and reducing the number of times sand suction is repeated.
[0026] Reference Figures 1-3 In a preferred embodiment, sand accumulation tanks 4 are fixedly connected to both sides of the double-sand tank 1. Sand discharge pipes 5 are provided above the sand accumulation tanks 4. Sand suction pumps 6 are provided at the top of the sand discharge pipes 5. A special hose 7 is fixedly connected to the other end of the sand suction pumps 6. Perforations are provided on both support plates 3. The outer side of the special hose 7 is fixedly connected to the inside of the perforation. A hanger bridge 9 is fixedly connected to the bottom of the support plates 3. A sand suction system 8 is provided inside the hanger bridge 9. The top of the sand suction system 8 is fixedly connected to the end of the special hose 7 away from the sand suction pump 6. The bottom ends of the two sand suction systems 8 are fixedly connected to the top of the sand suction vertical pipe 10. A sand suction head 11 is fixedly connected to the bottom of the sand suction vertical pipe 10. The sand suction head 11 is located between the two vibrators 1208.
[0027] Working principle: The slope inside the dual-chamber sand tank 1 guides the accumulated sand in the water to slide naturally to a fixed position. As the sand accumulates, the vibrator 1208 of the auxiliary sand suction component 12 remains in contact with the bottom of the tank. After the sand suction command is issued, the vibrator 1208 immediately starts and generates high-frequency vibration, which disperses the sand particles that were originally attached to the bottom of the tank, changing the sand particles from solid clumps to loose particles, making them easier to collect later. At the same time, the air pump 1212 above the support plate 3 starts to operate, compressing... Gas is delivered to the dispersion pipe 1210 through the air blowing pipe 1211. The dispersion pipe 1210 evenly distributes the gas to multiple air blowing heads 1209 on both sides of the moving frame 1205. The air blowing heads 1209 on both sides simultaneously blow air outward, forming a directional airflow that gathers the dispersed sand particles towards the center of the sand suction head 11, preventing the sand particles from dispersing and remaining at the bottom of the pool. Once the sand particles are gathered around the sand suction head 11, the sand suction system 8 starts and generates a strong suction force, and the sand suction head 11 sucks in the gathered sand particles. Sand particles enter the sand suction system 8 through the sand suction vertical pipe 10, and are then transported to the sand discharge pipe 5 through the special hose 7. The sand suction pump 6 continuously provides power to finally transport the sand particles in the sand discharge pipe 5 to the sand accumulation tank for storage. After the sand suction operation is completed, the drive motor 1202 of the auxiliary sand suction component 12 starts, driving the rotating shaft 1203 to rotate and gradually tightening the pulling rope 1204. The rope pulls the moving frame 1205 to move upward along the sand suction vertical pipe 10, causing the vibrator 1208 to detach from the bottom of the tank. At this time, the staff can clean the outside of the vibrator 1208 to remove the attached residual sand particles. After cleaning, the drive motor 1202 rotates in reverse, the rotating shaft 1203 releases the pulling rope 1204, and the moving frame 1205 returns to its original position under the assistance of gravity and the compression spring 1207. The vibrator 1208 then re-engages tightly with the bottom of the double-trough sand tank 1, and the entire system returns to its initial state, waiting for the next sand accumulation to reach the threshold before starting the sand suction operation.
[0028] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
