Description

Technical Field

[0001] This utility model relates to the field of ferric chloride preparation technology, and in particular to an automatic dilution and preparation device for liquid ferric chloride. Background Technology

[0002] Liquid ferric chloride (FeCl3) is an important chemical substance, mainly used as a flocculant and precipitant to remove pollutants such as heavy metals, phosphates, and sulfides from drinking water, industrial wastewater, and municipal sewage. It has the effects of decolorization, deodorization, oil removal, sterilization, and reduction of COD and BOD, and is suitable for the purification treatment of drinking water, industrial water, and swimming pool circulating water.

[0003] Liquid ferric chloride requires dilution during use, and this dilution must strictly adhere to the principle of first adding water (diluent) to the dilution container, and then slowly adding the liquid ferric chloride stock solution to the water. In existing technologies, because the equipment used for dilution operations has a fixed volume, the inlet height is also fixed. The required equipment volume varies when diluting different proportions of liquid ferric chloride. For dilution operations with lower dilution degrees, the liquid ferric chloride stock solution fed from a fixed position will impact the diluent (water), easily causing violent reactions and splashing. Furthermore, the harmful gases generated during the dilution process cannot be dealt with promptly, posing a safety hazard to operators. Therefore, this invention proposes an automatic dilution and preparation device for liquid ferric chloride to address the shortcomings of existing technologies. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide an automatic dilution and preparation device for liquid ferric chloride. This device features a movable top cover controlled by a lifting mechanism located above the inside of the dilution and preparation tank. The mixing and stirring mechanism, the raw liquid pipe, and the diluent pipe are all mounted on the movable top cover. The position of the movable top cover can be adjusted according to the dilution volume, allowing the raw liquid pipe and the diluent pipe to feed into the liquid surface, thus avoiding splashing caused by feeding from a height.

Detailed Implementation

[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] Example 1

[0019] according to Figure 1-3As shown in the figure, this embodiment proposes an automatic dilution and preparation device for liquid ferric chloride, including a dilution and preparation tank 1, a movable top cover 2, a lifting mechanism, a raw material pipe 3, and a diluent pipe 4. The movable top cover 2 is located on the upper part of the inside of the dilution and preparation tank 1. The lifting mechanism is located on the outside of the dilution and preparation tank 1 and is connected to the movable top cover 2. A mixing and stirring mechanism is located inside the dilution and preparation tank 1 and is rotatably installed with the movable top cover 2. The movable top cover 2 has a raw material pipe 3 and a diluent pipe 4 communicating with the inside of the dilution and preparation tank 1. A purification cover is located on the top of the movable top cover 2. 5. The top of the purification cover 5 is provided with a first hose 6 and a second hose 7. One end of the first hose 6 is provided with a raw liquid delivery pipe 8, and the second hose 7 is provided with a diluent delivery pipe 9. The raw liquid delivery pipe 8 and the diluent delivery pipe 9 are respectively provided with a first electronic metering valve 10 and a second electronic metering valve 11. The raw liquid pipe 3 and the diluent pipe 4 are respectively connected to the first hose 6 and the second hose 7. The purification cover 5 is provided with a purification component inside. An exhaust fan 12 is provided on one side of the purification cover 5. The exhaust fan 12 is connected to the inside of the purification cover 5. An exhaust seat 13 is provided at the bottom inside the movable top cover 2.

[0020] In use, the automatic dilution and preparation device for liquid ferric chloride of this invention adjusts the position and height of the movable top cover 2 according to the predetermined total dilution amount. First, the diluent (water) is quantitatively added to the dilution preparation tank 1 through a piping system consisting of a diluent delivery pipe 9, a second flexible hose 7, a second electronic metering valve 11, and a diluent pipe 4. Then, the liquid ferric chloride stock solution is quantitatively added to the dilution preparation tank 1 through a piping system consisting of a stock solution delivery pipe 8, a second flexible hose 7, a first electronic metering valve 10, and a stock solution pipe 3. Since the lower end of the stock solution pipe 3 is close to the surface of the diluent, splashing caused by impact can be effectively avoided. During this process, synchronous stirring can be performed by a mixing and stirring mechanism to improve the uniformity of dilution. Harmful gases produced during dilution enter the movable top cover 2 through the exhaust seat 13 and then into the purification cover 5. They are then drawn in by the exhaust fan 12, purified by the purification components, and finally discharged through the exhaust fan 12.

In this invention, the two lifting cylinders 16 are controlled synchronously by a controller. When the movable top cover 2 moves up and down, the output end of the lifting cylinder 16 moves, causing the movable top cover 2 to move.

[0022] The mixing mechanism includes a stirring shaft 17, blades 18, and a motor 19.

The motor 19 is connected to the stirring shaft 17. By placing the motor 19 inside the hollow cover 20, heat dissipation of the motor 19 is achieved.

[0023] The purification assembly consists of multiple sets of annular activated carbon adsorption plates 21. Each set of annular activated carbon adsorption plates 21 is threadedly connected to the inner wall of the purification cover 5. The size of the central hole on each annular activated carbon adsorption plate 21 is adapted to the size of the hollow cover 20. The suction end of the exhaust fan 12 is located above the uppermost set of annular activated carbon adsorption plates 21. The multiple threaded annular activated carbon adsorption plates 21 facilitate disassembly and replacement.

[0024] The bottom of the dilution and mixing tank 1 is funnel-shaped, and a discharge pipe 22 is provided at the bottom of the dilution and mixing tank 1. A control valve 23 is provided on the discharge pipe 22. The discharge pipe 22 is used to discharge the final diluted liquid ferric chloride.

[0025] This invention features a movable top cover 2 controlled by a lifting mechanism installed above the interior of the dilution mixing tank 1 via an exhaust seat 13. The mixing and stirring mechanism, the raw liquid pipe 3, and the diluent pipe 4 are all installed on the movable top cover 2. The position of the movable top cover 2 can be adjusted according to the dilution volume, allowing the raw liquid pipe 3 and the diluent pipe 4 to feed into the liquid surface, thus avoiding splashing caused by feeding from a high position. By installing a purification cover 5 on the top of the movable top cover 2, the purification components inside the purification cover 5, in conjunction with the exhaust fan 12, can purify and discharge the harmful gases generated during the dilution process, thus avoiding safety hazards.
