Description

Technical Field

[0001] This utility model relates to the technical field of flocculation reaction devices, specifically a stirred flocculation reaction device for wastewater treatment. Background Technology

[0002] A flocculation reactor is a device used in wastewater treatment. It involves adding flocculants to cause fine particles in the water to aggregate into larger flocs, which are then removed through sedimentation or filtration. This device typically includes a stirring system, a reagent dosing system, and a reaction tank, designed to promote sufficient contact and reaction between the flocculant and suspended solids in the water.

[0003] Existing stirred flocculation reactors are widely used in wastewater treatment. However, a significant problem exists in practical application: excessive shear force generated during stirring can cause the initially formed flocs to break down, thus affecting sedimentation efficiency. During stirring, the flocculant reacts with suspended solids in the wastewater to form flocs. Appropriate stirring speed and force are crucial to ensuring the successful growth and eventual sedimentation of these flocs. If the shear force is too high during stirring, the flocs will break down prematurely, forming smaller particles. These smaller particles settle slowly and are less effective at removing pollutants from the water. Excessive shear force not only affects the stability of the flocs but may also increase the burden on subsequent treatment stages, leading to reduced flocculation efficiency and unsatisfactory sedimentation results.

[0004] In view of this, we propose a stirred flocculation reaction device for wastewater treatment. Utility Model Content

[0005] The purpose of this invention is to provide a stirred flocculation reactor for wastewater treatment. This stirred flocculation reactor for wastewater treatment solves the problem that in existing stirred flocculation reactors, excessive shear force during wastewater treatment can cause floc breakage, affecting sedimentation effect and treatment efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A stirred flocculation reactor for wastewater treatment includes a body with a base supporting it. A stirring mechanism is mounted on the body, comprising: an electromagnetic drain pipe at the bottom of the body, equipped with a solenoid valve for controlling the discharge of wastewater or reaction liquid; and a high-pressure air inlet pipe at the top of the body, with an upper ring-shaped hollow component fixedly connected to its bottom. A lower ring-shaped hollow component is rotatably connected to the bottom of the upper ring-shaped hollow component, and an air delivery column is rotatably connected to the bottom of the lower ring-shaped hollow component. A middle... The hollow connecting ring has a small gear fixedly connected to its bottom. A gear ring is fixedly connected to the bottom of the inner wall of the machine body, and the inner wall of the gear ring meshes with the small gear. Several oblique jet nozzles are fixedly connected to the inner wall of the hollow connecting ring, and the oblique jet nozzles are arranged in a circumferential array on the oblique jet nozzles. A connecting pipe is provided on the inner wall of the hollow connecting ring, one end of which is fixedly connected to the inner wall of the hollow connecting ring, and the other end of which is fixedly connected to the inner wall of the air supply column. The small gear is made of magnetic material, and an oscillation mechanism is provided on the inner wall of the base. The small gear oscillates by magnetic force driving the oscillation mechanism.

[0008] Preferably, the body is provided with a cover, which is used to close the top of the device, and the cover is not completely sealed to the body.

[0009] Preferably, a positioning ring is rotatably connected to the outer wall of the hollow connecting ring, and the outer wall of the positioning ring is rotatably connected to the inner wall of the machine body.

[0010] Preferably, a plurality of hollow connecting rings are provided, and the hollow connecting rings are arranged in a linear array on the gas delivery column.

[0011] Preferably, the outer wall of the upper ring-shaped hollow component is fixedly connected to the inner wall of the machine body, and the outer wall of the lower ring-shaped hollow component is rotatably connected to the inner wall of the machine body.

[0012] Preferably, the oscillation mechanism includes a ring-shaped component, which is fixedly connected to the inner wall of the base.

[0013] Preferably, the inner wall of the annular component is provided with an arc-shaped groove, and an annular spring is provided on the inner wall of the arc-shaped groove. One end of the annular spring is fixedly connected to the inner wall of the arc-shaped groove, and the other end of the annular spring is fixedly connected to an annular magnet. The outer wall of the annular magnet is slidably connected to the arc-shaped groove.

[0014] By employing the above technical solution, this utility model provides a stirred flocculation reaction device for wastewater treatment. It possesses at least the following beneficial effects:

[0015] 1. This utility model incorporates a stirring mechanism. When the inclined jet nozzle rotates around the air delivery column, it also revolves around the inner wall of the machine body. The airflow released by the inclined jet nozzle has low shear force. The lift of the bubbles and the flow of the airflow do not directly generate strong shear force like mechanical stirring, thus avoiding damage to the initially formed flocs. The rising speed of the bubbles is relatively slow, which can provide moderate mixing without causing the flocs to split or break.

[0016] 2. This utility model incorporates a vibration mechanism. The ring-shaped magnet strikes the inner wall of the ring-shaped component, providing vibrational force to the machine body. This vibrational force helps break up localized dead zones in the liquid, making the water flow more uniform and thus enhancing the flocculation effect. Vibration promotes the dispersion of bubbles in the liquid, prevents bubbles from agglomerating into large bubbles, ensures uniform bubble distribution in the liquid, increases the contact area between bubbles and suspended matter and flocs in the liquid, and improves flocculation efficiency.

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.

[0025] Please see Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a stirred flocculation reaction device for sewage treatment, including a body 1, a base 3 at the bottom of the body 1, the base 3 supporting the body 1 to maintain the stability and safety of the device and ensure that the equipment will not tilt or shift during operation. A stirring mechanism 4 is provided on the body 1, the stirring mechanism 4 including: an electromagnetic drain pipe 41, located at the bottom of the body 1, equipped with an electromagnetic valve for controlling the discharge of sewage or reaction liquid, facilitating automated control and precise discharge, ensuring high efficiency of the treatment process and timely liquid discharge; and a high-pressure air inlet pipe 42, located at the top of the body 1, with an upper ring-shaped hollow component 43 fixedly connected to the bottom of the high-pressure air inlet pipe 42, and a lower ring-shaped hollow component 44 rotatably connected to the bottom of the upper ring-shaped hollow component 43. A hollow ring 44 is rotatably connected to an air supply column 45 at its bottom. A hollow connecting ring 46 is fixedly connected to the outer wall of the air supply column 45. A small gear 48 is fixedly connected to the bottom of the hollow connecting ring 46. A gear ring 49 is fixedly connected to the bottom of the inner wall of the body 1. The inner wall of the gear ring 49 meshes with the small gear 48. An oblique jet nozzle 410 is fixedly connected to the inner wall of the hollow connecting ring 46. Several oblique jet nozzles 410 are provided, and a circular array of oblique jet nozzles 410 is provided on the oblique jet nozzles 410. A connecting pipe 411 is provided on the inner wall of the hollow connecting ring 46. One end of the connecting pipe 411 is fixedly connected to the inner wall of the hollow connecting ring 46, and the other end of the connecting pipe 411 is fixedly connected to the inner wall of the air supply column 45. The small gear 48 is made of magnetic material. An oscillation mechanism 5 is provided on the inner wall of the base 3. The small gear 48 oscillates by magnetic force driving the oscillation mechanism 5.

[0026] The body 1 is equipped with a cover 2, which is used to seal the top of the device to prevent sewage from splashing out. The cover 2 is not completely sealed to the body 1, so gas can be discharged. The outer wall of the hollow connecting ring 46 is rotatably connected to the positioning ring 47. The outer wall of the positioning ring 47 is rotatably connected to the inner wall of the body 1. The positioning ring 47 is used to support the middle part of the gas delivery column 45 during rotation. Several hollow connecting rings 46 are provided. The hollow connecting rings 46 are arranged in a linear array on the gas delivery column 45 to stir the upper and lower layers, promote the full mixing of water and the uniform formation of flocs, and improve the reaction efficiency. The outer wall of the upper ring-shaped hollow part 43 is fixedly connected to the inner wall of the body 1, and the outer wall of the lower ring-shaped hollow part 44 is rotatably connected to the inner wall of the body 1.

[0027] The oscillation mechanism 5 includes a ring-shaped component 51, which is fixedly connected to the inner wall of the base 3. An arc-shaped groove 52 is provided on the inner wall of the ring-shaped component 51, and an annular spring 53 is provided on the inner wall of the arc-shaped groove 52. One end of the annular spring 53 is fixedly connected to the inner wall of the arc-shaped groove 52, and the other end of the annular spring 53 is fixedly connected to an annular magnet 54. The outer wall of the annular magnet 54 is slidably connected to the arc-shaped groove 52.

[0028] When the stirred flocculation reaction device for sewage treatment of this utility model is in use, during the flocculation reaction inside the machine body 1, the air compressor is connected to the high-pressure air inlet pipe 42. The high-pressure air in the high-pressure air inlet pipe 42 passes through the upper ring hollow part 43, the lower ring hollow part 44, the air delivery column 45, the hollow connecting ring 46, and finally is discharged through the oblique jet nozzle 410, which stirs the liquid and mixes the gas inside the machine body 1, promotes the flocculation reaction, and improves the floc formation efficiency.

[0029] When the angled jet nozzle 410 discharges jet gas, it experiences a reaction force, causing the hollow connecting ring 46 to rotate. The hollow connecting ring 46 drives the air delivery column 45 to rotate, which in turn drives the pinion gear 48 to rotate. Under the action of the gear ring 49, the pinion gear 48 drives the air delivery column 45 to rotate around the inner wall of the machine body 1. This causes the angled jet nozzle 410 to rotate around the air delivery column 45 and also around the inner wall of the machine body 1. By making the rotation trajectory of the angled jet nozzle 410 more complex, the airflow can be evenly distributed in multiple directions, ensuring thorough mixing and stirring of the gas and liquid, and improving the uniformity and efficiency of the flocculation reaction. In addition, this rotational motion helps to prevent the aggregation of air bubbles in the liquid, making the air bubbles more evenly distributed in the water, further improving the wastewater treatment effect.

[0030] Meanwhile, the airflow released at the angled jet nozzle 410 has low shear force. The lift of the bubbles and the flow of the airflow do not directly generate strong shear force like mechanical stirring, thus avoiding damage to the initially formed flocs. The slower rising speed of the bubbles provides moderate mixing without causing the flocs to split or break apart.

[0031] Simultaneously, when the pinion 48 rotates, it drives the annular magnet 54 to move a certain distance on the inner wall of the arc-shaped groove 52 via magnetic force. Then, when the pinion 48 moves to the limit position of the annular magnet 54, the annular magnet 54 quickly returns to its original position under the action of the annular spring 53. The annular magnet 54 strikes the inner wall of the annular component 51, providing a vibrational force to the machine body 1. This vibrational force helps to break up local dead zones in the liquid, making the water flow more uniform, thereby enhancing the flocculation effect. Vibration promotes the dispersion of bubbles in the liquid, prevents bubbles from agglomerating into large bubbles, ensures that bubbles are evenly distributed in the liquid, increases the contact area between bubbles and suspended matter and flocs in the liquid, and improves flocculation efficiency.
