Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater treatment equipment, and in particular to a dosing device for industrial wastewater treatment. Background Technology

[0002] In the course of industrial production, many industries such as chemical engineering, electroplating, printing and dyeing, and pharmaceuticals generate industrial wastewater with complex compositions and high polluting properties. If this wastewater is discharged directly without effective treatment, it will cause serious damage to the ecological environment, including water bodies and soil, and endanger human health.

[0003] As a key piece of equipment in the industrial wastewater treatment process, the dosing device's main function is to precisely add various agents to the wastewater. Through a series of chemical reactions such as flocculation, neutralization, and oxidation-reduction, it removes heavy metal ions, organic matter, suspended solids, and adjusts the pH of the wastewater, so that the treated wastewater meets the discharge standards.

[0004] Traditional dosing devices mostly rely on the rotation of a single stirring rod to achieve reagent mixing. The stirring trajectory is fixed and limited to a local area, which easily creates mixing dead zones in the corners of the dosing tank. Especially for poorly soluble reagents, such as the polymeric flocculant PAM, insufficient stirring can easily lead to particle agglomeration and precipitation, resulting in fluctuations in the concentration of subsequently added reagents. This not only affects the wastewater treatment effect but also causes reagent waste or substandard treatment. Therefore, a dosing device for industrial wastewater treatment is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a dosing device for industrial wastewater treatment, which aims to solve the problem in the prior art that "relies on a single stirring rod to rotate and mix the agent, the stirring trajectory is fixed and limited, and it is easy to form a mixing dead corner at the edge of the dosing tank".

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dosing device for industrial wastewater treatment, comprising a support frame, a control box fixedly connected to the right side of the support frame, a support bracket fixedly connected to the inner wall of the support frame, a support member rotatably connected to the inner wall of the support bracket, a dosing tank fixedly installed on the inner wall of the support member, an auxiliary component provided on the left side of the support frame, the auxiliary component including a reduction motor fixedly connected to the outside of the support frame, a drive member fixedly connected to the outside of the output shaft of the reduction motor, a swing arm fixedly connected to the outside of the rotatable connection between the support member and the support bracket, a horizontally penetrating groove provided on the inner wall of the swing arm, the drive member sliding on the inner wall of the groove, a stirring rod rotatably connected to the upper inner wall of the dosing tank, a bevel gear fixedly connected to the upper part of the stirring rod, a guide frame fixedly connected to the upper part of the support frame, and teeth meshing with the bevel gear fixedly connected to the outside of the guide frame.

[0007] As a further description of the above technical solution:

[0008] The driving component includes a connector, and a connecting lever is slidably connected to the inner wall of the connector. The lower part of the connecting lever has multiple sets of insertion holes. The connector and the connecting lever are fixedly connected by an adjusting bolt, which passes through the insertion holes.

[0009] As a further description of the above technical solution:

[0010] The connecting lever is cylindrical on the side near the swing arm.

[0011] As a further description of the above technical solution:

[0012] The guide frame is designed to be arc-shaped.

[0013] As a further description of the above technical solution:

[0014] The center of the guide frame is the connection point between the support frame and the support member.

[0015] As a further description of the above technical solution:

[0016] The support frame is configured in a V shape.

[0017] As a further description of the above technical solution:

[0018] A metering pump is fixedly connected to the right side of the support frame, and the metering pump is connected to the inside of the dosing tank through a hose.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, the guide frame is set in an arc shape and the center of the circle coincides with the rotating connection of the support frame and the support component. When the dosing tank swings, the bevel gear on the upper part of the stirring rod will rotate along the teeth on the outside of the guide frame, thereby driving the stirring rod to rotate and stir in the dosing tank. The rotation and stirring further disperses the convective agent formed by the swing, so that the agent concentration tends to be uniform in a short time.

[0021] 2. In this utility model, the driving component consists of a connecting component and a connecting lever. By adjusting the bolts that pass through the insertion holes at different positions on the connecting lever, the length of the connecting lever extending out of the connecting component can be changed to adapt to the high-intensity mixing requirements of different antidotes.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] Reference Figure 1 - Figure 3This utility model provides an embodiment of a dosing device for industrial wastewater treatment, comprising a support frame 1, which serves as the basic frame of the device and is directly connected to the ground or the main body of the wastewater treatment equipment. It provides a stable installation platform for all components, including a control box 2, a support frame 3, and a metering pump. The control box 2 is fixedly connected to the right side of the support frame 1 and is electrically connected to a reduction motor 61 and a metering pump, allowing adjustment of the speed of the reduction motor 61 and the dosing flow rate of the metering pump. A support frame 3 is fixedly connected to the inner wall of the support frame 1. The support frame 3 is V-shaped, providing precise rotational support for the swinging of the dosing tank 5. A support member 4 is rotatably connected to the inner wall of the support frame 3, serving as a bridge between the dosing tank 5 and the support frame 3, and bearing the functions of fixing and transmitting the swinging motion of the dosing tank 5. The dosing tank 5 is fixedly installed on the inner wall of the support member 4, serving as a mixing vessel for the reagent and water. The container is designed to accommodate the single-use dosage of chemicals for industrial wastewater treatment. Its smooth, corrosion-resistant inner wall, made of 304 stainless steel or PPH plastic, prevents chemicals from corroding the container and causing impurities to enter. It provides space for the rotating and oscillating motion of the stirring rod 67. Through the combined effects of oscillation convection and rotational stirring, it ensures uniform mixing of the chemicals within the container, preventing sedimentation or agglomeration. An auxiliary component 6 is located on the left side of the support frame 1. This component includes a geared motor 61 fixedly connected to the outside of the support frame 1. Its output shaft drives the drive component 62 to rotate, converting electrical energy into mechanical rotational power. It features a speed reduction function, and the output speed can be adjusted to 5-10 r / min via the control box 2. This ensures smooth, impact-free oscillation of the dosing tank 5 due to excessive speed, preventing violent shaking and chemical spillage caused by excessive rotation.

[0030] Reference Figure 1 - Figure 3A drive component 62 is fixedly connected to the outer side of the output shaft of the geared motor 61, serving as the transmission medium between the power of the geared motor 61 and the swing arm 63, while also allowing for adjustable swing amplitude. A swing arm 63 is fixedly connected to the outer side of the rotatable connection between the support component 4 and the support frame 3. When the drive component 62 slides within the groove 64, the swing arm 63 swings in an arc around the rotation axis, thereby causing the support component 4 and the dosing tank 5 to swing synchronously. A groove 64 is horizontally provided through the inner wall of the swing arm 63, providing a sliding track for the connecting lever 622 of the drive component 62, ensuring that the drive component 62 can push the swing arm 63 to swing along a fixed trajectory when rotating. The drive component 62 slides on the inner wall of the groove 64. A stirring rod 67 is rotatably connected through the upper inner wall of the dosing tank 5. When it rotates with the bevel gear 66, the stirring blades on the rod disperse the medicine. The convective agent generated by the oscillation is further dispersed to eliminate mixing dead zones. A bevel gear 66 is fixedly connected to the upper part of the stirring rod 67, and a guide frame 65 is fixedly connected to the upper part of the support frame 1. The guide frame 65 is set in an arc shape, and the center of the guide frame 65 is the connection point between the support frame 3 and the support member 4. This ensures that when the dosing tank 5 oscillates, the bevel gear 66 can always roll along the teeth on the outside of the guide frame 65 to avoid disengagement. Teeth that mesh with the bevel gear 66 are fixedly connected to the outside of the guide frame 65. When the dosing tank 5 oscillates and drives the bevel gear 66 to roll along the teeth, the bevel gear 66 converts the linear rolling motion into its own rotational motion, which in turn drives the stirring rod 67 to rotate in the dosing tank 5. The stirring power comes entirely from the oscillation of the dosing tank 5, eliminating the need for a separate stirring motor, simplifying the structure and reducing energy consumption.

[0031] Reference Figure 2 - Figure 4 The driving component 62 includes a connecting component 621. A connecting lever 622 is slidably connected to the inner wall of the connecting component 621. The connecting lever 622 extends into the slide groove 64 of the swing arm 63. When rotating, it slides in the slide groove 64, pushing the swing arm 63 to swing around the rotation axis, converting the rotational power of the motor into the reciprocating swing power of the swing arm 63. The lower part of the connecting lever 622 has multiple sets of insertion holes 623. The connecting component 621 and the connecting lever 622 are fixedly connected by adjusting bolts 624. The adjusting bolts 624 pass through the insertion holes 623. By adjusting the bolts 624 passing through different insertion holes 623, the length of the connecting lever 622 extending out of the connecting component 621 can be changed. The longer it extends, the greater the swing amplitude of the driving swing arm 63 (maximum 60°), which is suitable for high-intensity mixing of difficult-to-dissolve drugs; the shorter it extends, the smaller the swing amplitude (minimum 15°), which is suitable for easily soluble drugs. The connecting lever 622 is cylindrical on the side near the swing arm 63, converting sliding friction into rolling friction, reducing frictional resistance with the slide groove 64, and preventing jamming. A metering pump is fixedly connected to the right side of the support frame 1. The metering pump is connected to the inside of the dosing tank 5 through a hose, accurately delivering the uniformly mixed reagent in the dosing tank 5 to the wastewater pool according to the wastewater treatment requirements.

[0032] Working principle: Before starting the device, the swing amplitude needs to be preset according to the solubility characteristics of the agent to be treated. By adjusting the bolt 624 in the drive component 62, select the insertion hole 623 at different positions on the connecting rod 622. If treating a difficult-to-dissolve agent such as a flocculant, the connecting rod 622 needs to extend a longer length from the inner wall of the connector 621, and then fix it with the adjusting bolt 624 through the corresponding insertion hole 623, so that the swing amplitude of the subsequent dosing tank 5 can reach a maximum of 60°. If treating an easily soluble agent such as a neutralizer, shorten the length of the connecting rod 622 extending from the connector 621, and fix it with the adjusting bolt 624. The swing amplitude of the dosing tank 5 can be reduced to a minimum of 15°, thus adapting to the mixing intensity requirements of different agents and completing the preparation before starting.

[0033] After the device is started, the output shaft of the geared motor 61 drives the drive component 62 to rotate as a whole. The connector 621 in the drive component 62 rotates synchronously with the output shaft. The connecting rod 622, which is slidably connected to the inner wall of the drive component 62, is cylindrical on the side near the swing arm 63. The cylindrical end of the rod extends into the horizontally penetrating groove 64 on the inner wall of the swing arm 63. As the connector 621 rotates, the cylindrical end of the connecting rod 622 rolls and slides along the track in the groove 64, thereby pushing the swing arm 63 to swing back and forth around the rotational connection between the support component 4 and the support frame 3. Since the inner wall of the support component 4 is fixedly connected to the dosing tank 5, the dosing tank 5 swings synchronously with the swing arm 63. The reagent in the tank is subjected to the inertia of the swing to form lateral and longitudinal convection, breaking the laminar flow state of traditional static stirring, and initially realizing the mixing of reagent and water.

[0034] As the dosing tank 5 swings, a rotating stirring rod 67, rotatably connected to the upper inner wall of the dosing tank 5, moves synchronously with it. A bevel gear 66, fixedly connected to the upper part of the stirring rod 67, meshes with the outer teeth of an arc-shaped guide frame 65 fixedly connected to the upper part of the support frame 1. Because the center of the guide frame 65 completely coincides with the rotating connection point of the support member 4 and the support frame 3, the bevel gear 66 can always roll tightly along the outer teeth of the guide frame 65 when the dosing tank 5 swings, preventing disengagement. The meshing and rolling of the bevel gear 66 drives its own rotation, which in turn drives the stirring rod 67 to rotate synchronously within the dosing tank 5. The blades on the stirring rod 67 further disperse the convective agent formed by the swinging motion, eliminating mixing dead zones in the corners of the dosing tank 5, significantly improving the mixing efficiency and uniformity of the agent, thereby improving the treatment effect of industrial wastewater.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
