Description

Technical Field

[0001] This utility model relates to a quantitative mixing device for wastewater treatment agents, belonging to the field of wastewater treatment technology. Background Technology

[0002] In wastewater treatment, various chemical agents, such as flocculants, pH adjusters, disinfectants, and nutrients, are often added to achieve treatment goals such as solid-liquid separation, pollutant degradation, sterilization, and biochemical regulation. Traditional mainstream dosing methods rely primarily on manual operation, where operators weigh, transport, and manually add the agents to the treatment facility based on experience or rough calculations. This method has significant drawbacks: the dosage depends on manual judgment, resulting in low accuracy and a tendency for under- or over-dosing, affecting treatment effectiveness (such as incomplete flocculation and pH imbalance) and wasting agents; the operation is cumbersome and labor-intensive, especially inefficient when frequent or batch dosing is required; and there are certain safety risks, as operators may directly come into contact with corrosive or hazardous chemicals.

[0003] To overcome the shortcomings of manual dosing, some automated or semi-automated dosing equipment has emerged on the market. A common technical solution involves using multiple fixed storage tanks, each equipped with an independent metering pump, pipeline, and valves, with the control system delivering the reagents at timed and quantitative intervals. While this type of equipment improves automation to some extent, it still has several limitations: First, the system structure is complex, occupies a large area, has cumbersome pipeline layout, and has high purchase and maintenance costs; second, its configuration is usually fixed, and once installed, it is inconvenient to adjust the types of reagents and dosing ranges, making it difficult to flexibly adapt to changes in processing technology or the need for sequential dosing of multiple reagents. Utility Model Content

[0006] Furthermore, an inlet baffle is provided at the bottom of the turntable, and the inlet baffle is fixedly connected to the mixing tank.

[0007] Furthermore, two mirror-aligned injection ports are provided on the inlet baffle, and the injection ports are perpendicularly aligned with the treatment agent through holes.

[0013] 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.

[0014] See Figures 1 to 8 This utility model provides a technical solution: a wastewater treatment agent quantitative mixing device, including a mixing tank 1, a turntable 2 above the mixing tank 1, a rotating shaft connector 21 connected to the middle of the turntable 2 by a bearing, a rotating shaft 3 fixedly connected to the rotating shaft connector 21, a motor 6 at the top of the rotating shaft 3, the motor 6 being fixedly connected to the rotating shaft 3, and the top of the motor 6 being fixedly connected to a fixing plate 7 to ensure that the motor will not move during operation. Multiple equally spaced treatment agent through holes 22 are opened around the rotating shaft connector 21 on the turntable 2, and slide rails 23 are opened on both sides of the treatment agent through holes 22. A limiting member 24 is slidably connected on the rail 23. An external limiting block 241 is rotatably connected to the tail end of the limiting member 24. An internal limiting block 242 is provided on both sides of the front end of the limiting member 24. Bottle head recesses 25 are provided on the other two sides of the treatment agent through hole 22. A metering bottle 4 is provided on the treatment agent through hole 22. A bottle head connector 41 is fixedly connected to the bottom of the metering bottle 4. A bottle head protrusion 42 is fixedly connected to the bottom of the bottle head connector 41. Limiting grooves 43 are provided on both sides of the bottle head connector 41. A limiting internal groove 44 corresponding to the internal limiting block 242 is provided in the limiting groove 43.

[0015] An inlet baffle 5 is provided at the bottom of the turntable 2, and the inlet baffle 5 is fixedly connected to the mixing tank 1. Two mirror-aligned injection ports 51 are provided on the inlet baffle 5, and the injection ports 51 are perpendicularly aligned with the treatment agent through holes 22. There are 6 treatment agent through holes 22.

[0016] The metering bottle 4 is inserted into the bottle head recess 25 through the bottle head protrusion 42, and the limiting member 24 slides into the limiting groove 43 and is engaged with the turntable 2. The rotating shaft 3 extends through the inlet baffle 5 into the mixing tank 1, and the lower end surface of the rotating shaft 3 is also provided with stirring blades.

[0017] During installation, align the bottle head protrusion 42 with and insert it into the bottle head recess 25 to achieve initial vertical positioning of the metering bottle. After the bottle head protrusion 42 is inserted into the bottle head recess 25, manually push the limiting member 24 along the slide rail 23 towards the bottle head connector so that its front end is embedded in the limiting groove 43.

[0018] After the limiting member 24 is fully slid into place, rotate the outer limiting block 241 at the tail of the limiting member 24 so that its two ends fit against the metering bottle 5 to prevent the limiting member 24 from sliding out. At the same time, the inner limiting block 242 is coaxially connected with the outer limiting block 241. As the outer limiting block 241 rotates, the inner limiting block also pops out and locks into the inner groove 44 to form a lock, thereby preventing the metering bottle from loosening or falling off during rotation or vibration.

[0019] Working principle: According to the types of agents and single dosage required by the wastewater treatment process, the operator pre-fills different wastewater treatment agents, such as flocculants and pH adjusters, into the corresponding quantitative bottles 4. The capacity of each quantitative bottle can be customized as needed to ensure that the capacity of a single bottle is the dosage for one time.

[0020] The metering bottle filled with the reagent is inserted into the corresponding bottle head recess 25 on the turntable 2 through the bottle head protrusion 42 at its bottom, and the limiting member 24 is pushed to slide along the slide rail 23, so that the internal limiting block 242 is engaged in the limiting internal groove 44 of the bottle head connector 41, completing a quick and secure installation. Six metering bottles can be installed on the turntable at the same time to accommodate multiple reagents or multiple dosings.

[0021] Motor 6 starts, driving the rotating shaft 3 to rotate reciprocally. It is programmed to rotate 3 times clockwise and then 3 times counterclockwise, repeating this cycle. This, in turn, drives the turntable 2 fixed to it and all the installed metering bottles 4 to rotate together. An inlet baffle 5 is fixed to the bottom of the turntable 2, which has two mirror-aligned injection ports 51. Through a preset program, the through-hole 22 of the treatment agent corresponding to the metering bottle 4 to be added is precisely rotated to a position perpendicularly aligned with one of the injection ports 51 on the inlet baffle before stopping.

[0022] At this time, the mouth of the metering bottle 4 is connected to the inside of the mixing tank 1 through the treatment agent through-hole 22 and the injection port 51. The operator can manually or through the designed pouring mechanism pour all the medicine in the metering bottle 4 into the mixing tank through the injection port. Since the capacity of each metering bottle 4 is fixed, the medicine poured in each time is the preset precise dose.

[0023] After the first reagent is added, motor 6 can be restarted to rotate turntable 2 to the next metering bottle 4 to be added, aligning it with the injection port 51 (which can be the same or a different one) for the metered addition of the second reagent. This process can be repeated to achieve automated or semi-automated addition of multiple reagents in the required order and quantity according to the process requirements.

[0024] After all the necessary chemicals are poured into the mixing tank 1, the motor 6 can continue to drive the stirring blades installed at the lower end of the rotating shaft 3 to rotate at high speed and perform reciprocating motion, so as to fully stir and mix the sewage and treatment agent in the tank, and ensure that the chemical reaction or physical treatment process is carried out uniformly and efficiently.

[0025] Obviously, the above embodiments are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, these obvious variations or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
