Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and more specifically to a jet-suction mixing assembly and its online flocculation mixing device. Background Technology

[0002] In water treatment, flocculation is a crucial step. Its purpose is to aggregate fine particles in the water into larger particles by adding flocculants, facilitating subsequent sedimentation or filtration. Traditional flocculation reactors primarily rely on mechanical agitation to mix the flocculant and water. However, this traditional method has several drawbacks, as follows:

[0003] 1. High maintenance costs: Flocculent material easily adheres to the impeller, resulting in reduced mixing efficiency and requiring frequent manual cleaning, which increases maintenance workload and costs.

[0004] 2. High energy consumption: Mechanical stirring requires a large amount of electricity to drive the stirring equipment, which increases energy consumption in the water treatment process and does not meet the requirements of energy conservation and emission reduction.

[0005] 3. Large footprint: Traditional flocculation reaction tanks have a large structure, requiring significant civil engineering costs and occupying a large area, which is a major limiting factor for water treatment plants with limited space.

[0006] 4. Poor flexibility: The operation of traditional flocculation reaction tanks requires a matching power and control system, the installation and commissioning process is complicated, and the requirements for the installation site are high, making it difficult to adapt to different working conditions and site conditions.

[0007] Although some improvements have been made in existing technologies, they have not fundamentally solved the above problems. Therefore, there is an urgent need for a new type of flocculation mixing device that can overcome the shortcomings of traditional mechanical stirring and achieve a highly efficient, energy-saving, and maintenance-free flocculation reaction process to meet the requirements of the modern water treatment industry for high efficiency, environmental protection, and economy.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] See appendix Figure 1 This utility model discloses a jet-suction hybrid injection assembly, comprising:

[0035] Water inlet pipe 1, one end of which has a spray nozzle 5 with a gradually decreasing diameter;

[0036] Adjustment frame 2 is connected to the outside of water inlet pipe 1 and can be adjusted in position along the axial direction of water inlet pipe 1;

[0037] The jet pipe 3 has one end fixedly connected to the adjusting frame 2 and corresponds to the spray port 5 of the water inlet pipe 1. The other end of the jet pipe 3 is in the shape of a trumpet with a gradually increasing diameter. The distance between the jet pipe 3 and the spray port 5 can be adjusted by the adjusting frame 2.

[0038] The arc-shaped guide plate 4 is fixed to the flared end of the jet pipe 3 by multiple support rods 6, with the concave surface of the arc-shaped guide plate 4 facing the flared end of the jet pipe 3.

[0039] To further optimize the above technical solution, the adjusting frame 2 consists of multiple bent rods 7, which are evenly distributed around the water inlet pipe 1. One end of each bent rod 7 is fixed to the end of the jet pipe 3, while the other end is adjustablely connected to the outer wall of the water inlet pipe 1. The adjusting frame 2, composed of multiple bent rods 7 evenly distributed around the water inlet pipe 1, allows for more flexible and stable adjustment of the distance between the jet pipe 3 and the spray nozzle 5, better adapting to the mixing requirements under different working conditions and further improving the mixing effect.

[0040] To further optimize the above technical solution, the end of the bent rod 7 connected to the water inlet pipe 1 has a slider 8 that fits snugly against the water inlet pipe 1. The slider 8 has a threaded hole, and an adjusting bolt 9 that tightens against the outer wall of the water inlet pipe 1 is connected inside the threaded hole. This allows for precise adjustment of the distance between the suction pipe 3 and the spray nozzle 5, making operation convenient and the connection more secure and reliable, ensuring the stable operation of the device.

[0041] To further optimize the above technical solution, the bottom outer side of the water inlet pipe 1 has a radially outward protruding variable diameter retaining ring 10, which is used to prevent the slider 8 from falling out of the water inlet pipe 1. This enhances the structural stability of the device, avoids equipment failure caused by the slider 8 falling out, and improves the reliability and service life of the equipment.

[0042] To further optimize the above technical solution, the ejector tube 3 consists of an annular rim 11, a straight tube 12, and a trumpet tube 13. The edge of the annular rim 11 is fixedly connected to the bent rod 7, and the wide end of the trumpet tube 13 is fixedly connected to the support rod 6. This structural design makes the ejector tube 3 more rational, better guides fluid flow, enhances the ejection effect, and improves mixing efficiency.

[0043] To further optimize the above technical solution, the end of the water inlet pipe 1 furthest from the spray nozzle 5 has a connecting flange 14. This facilitates the connection of the water inlet pipe 1 with other pipes or equipment, improving the ease of installation and versatility of the device, and making equipment integration and maintenance easier.

[0046] In this embodiment, the design of the arc-shaped guide plate 4 can form a circulating mixed flow with a flow rate of more than 3 times the inlet flow rate.

[0047] In this embodiment, the flocculant premixed water inlet system 18 includes a water supply pipe 19 connected to the water inlet 16. The water supply pipe 19 has a dosing branch pipe 20, which is connected to a dosing pump 21. The dosing pump 21 is connected to a flocculant supply tank 22. By adding flocculant from the flocculant supply tank 22 into the water supply pipe 19 via the dosing pump 21, precise flocculant dosing is achieved, ensuring the effectiveness of the flocculation reaction and improving the quality and efficiency of water treatment.

[0048] To further optimize the above technical solution, the inlet 16 has a flange structure and is connected to the connecting flange 14 at the end of the inlet pipe 1 furthest from the spray nozzle 5. This connection method is simple and reliable, facilitates installation and maintenance, and improves the stability and service life of the equipment.

[0049] This embodiment provides an online flocculation reaction device that requires no power system, is maintenance-free, and has high mixing efficiency, achieving automatic mixing through the principle of fluid dynamics.

[0050] This embodiment requires no power system; it relies solely on the inlet water pressure to drive the jet suction effect, thus eliminating the need for an external power source.

[0051] The tank 15 structure provided in this embodiment is as follows: Figure 2 As shown, the inlet 16 is at the top of the tank 15, and the outlet 17 is at the bottom of the tank 15.

[0052] The workflow of the online flocculation mixing device provided in this embodiment is as follows:

[0054] 2. Raw water is sprayed out at high speed from inlet pipe 1 to form a negative pressure zone;

[0055] 3. The suction pipe 3 draws in the fluid inside the tank, forming a mixed flow;

[0056] 4. The arc-shaped guide plate 4 guides the fluid to form a vertical swirling flow, which enhances the flocculation reaction.

[0057] Traffic adaptation operation:

[0058] Loosen the adjusting bolt 9 and slide the adjusting bracket 2 to change the distance between the injection nozzle 5 and the suction pipe 3;

[0059] Low flow rate conditions: Reduce spacing to enhance suction force;
