Description

Technical Field

[0001] This utility model relates to the field of fine chemical proportioning and metering, and in particular to a device for precise metering and proportioning of raw materials for perfluoropolyether siloxane anti-fingerprint agent. Background Technology

[0002] Perfluoropolyether siloxane anti-fingerprint agents are functional coating materials widely used on the surfaces of consumer electronics, optical devices, and other products. Their preparation process places extremely high demands on the precision of raw material proportioning and the mixing environment. Especially in the raw material feeding stage, if multiple solid particulate precursor materials are involved, achieving precise and controllable metering directly determines the performance and batch stability of the final product.

[0003] Most existing devices for raw material proportioning employ simple weighing or manual addition methods. These methods have significant drawbacks when dealing with small-batch, high-precision fine chemical production: firstly, simple gravity or vibration feeding cannot achieve intermittent and constant-volume precise metering, easily leading to deviations in the feeding amount due to changes in material bulk density; secondly, when mixing multiple raw materials, they need to be weighed separately before being poured in, which is cumbersome and inefficient. Furthermore, if the feeding system is poorly designed and lacks independent control over the feeding process, cross-contamination or proportioning errors are highly likely. In addition, because anti-fingerprint agent raw materials are sensitive to ambient temperature, existing simple proportioning tanks often lack effective insulation or corrosion protection, making it difficult to mix raw materials in a stable temperature environment and failing to guarantee the purity of the raw materials during the reaction process.

[0004] Therefore, this invention proposes a precise metering and proportioning device for perfluoropolyether siloxane anti-fingerprint agent raw materials to address the shortcomings of existing technologies. Summary of the Invention

The viewing window is embedded in a mounting groove opened in the side wall of the storage tank body, and the viewing window faces the interior of the inner tank. The scale lines are etched on the transparent surface of the viewing window to assist in measuring the liquid level height inside the storage tank body.

[0010] Preferably, the side wall of the storage tank body is also provided with a tank door, which is rotatably connected to an inspection port opened on the side wall of the storage tank body via a hinge.

[0019] 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.

[0020] Reference Figures 1-5 This utility model provides a device for precise metering and proportioning of raw materials for perfluoropolyether siloxane anti-fingerprint agent, which solves the problems in the prior art of making precise metering of solid raw materials and lack of necessary heat preservation and corrosion protection.

[0021] Specifically, it includes a storage tank body 1, an inlet pipe 2 fixedly connected to the top of the storage tank body 1, and an outlet pipe 5 fixedly connected to the bottom of the storage tank body 1. The storage tank body 1 serves as the core carrier of the entire device, carrying raw materials and solvents. The storage tank body 1 internally includes an inner tank 101 and an outer tank 102 sleeved outside the inner tank 101. An insulation jacket is formed between the inner tank 101 and the outer tank 102. This double-layer tank structure can effectively ensure the temperature stability of the materials inside the tank during the proportioning and mixing process, and meet the requirements of pressure bearing and heat conduction.

[0022] A batching mechanism 3 is also fixedly connected to the top of the storage tank body 1. The batching mechanism 3 is used to achieve precise metering of multiple raw materials. The batching mechanism 3 adopts a dual-path independent metering and conveying method to achieve simultaneous and independent control of the feeding of two raw materials.

[0023] The batching mechanism 3 includes a hopper 301, and a first batching box 303 and a second batching box 307 disposed at the bottom of the hopper 301. A partition 302 is fixedly provided inside the hopper 301. The partition 302 is vertically fixedly connected to the inner wall of the hopper 301, dividing the internal space of the hopper 301 into two independent chambers that are not connected to each other. These chambers are used to hold two different raw materials that need to be mixed in different proportions, effectively avoiding cross-contamination of the raw materials before they are added.

[0024] A first motor 305 is fixedly connected to the side wall of the first batching box 303. The output shaft of the first motor 305 penetrates the side wall of the first batching box 303 and extends into the interior of the first batching box 303. The end of the output shaft is connected to a first rotating fan 304 via a key. The first rotating fan 304 is rotatably disposed inside the first batching box 303, and its blades have a fixed volumetric interval. When the first motor 305 drives the first rotating fan 304 to rotate, it can realize intermittent, quantitative volumetric metering and feeding of raw materials in the upper hopper 301. The bottom of the first batching box 303 is fixedly connected to the interior of the inner tank 101 through a first feeding pipe 306, serving as the channel for the first type of raw material to enter the main tank.

[0025] Similarly, a second motor 309 is fixedly connected to the side wall of the second ingredient box 307. The output shaft of the second motor 309 penetrates the side wall of the second ingredient box 307 and extends into the interior of the second ingredient box 307. The end of the output shaft is connected to and driven by a second rotating fan 308 via a pin. The second rotating fan 308 is rotatably disposed inside the second ingredient box 307 and is also used to realize the quantitative metering and dispensing of the second raw material. The bottom of the second ingredient box 307 is fixedly connected to the interior of the inner tank 101 via a second discharge pipe 310, serving as a channel for the second raw material to enter the main tank.

[0026] This dual-path dispensing structure can precisely control the amount and ratio of two solid raw materials by independently controlling the rotation speed and start-up time of the first motor 305 and the second motor 309, thus meeting the precise requirements of perfluoropolyether siloxane anti-fingerprint agent for the raw material ratio.

[0027] Based on the above embodiments, the present invention may further include the following preferred technical solutions: To facilitate real-time monitoring of the liquid level within the tank and aid in measurement, an observation mechanism 4 is provided on the side wall of the storage tank body 1. The observation mechanism 4 includes a viewing window 401 and a scale line 402. The viewing window 401 is embedded in a mounting groove on the side wall of the storage tank body 1, ensuring that the inner surface of the viewing window 401 faces the interior of the inner tank 101, while its outer surface is flush with the outer wall of the outer tank 102. The scale line 402 is etched onto the transparent surface of the viewing window 401, allowing operators to accurately read the liquid level in the inner tank 101, particularly when injecting solvent into the inlet pipe 2, effectively assisting in measurement.

[0028] To facilitate inspection and maintenance of the interior of the storage tank body 1, a tank door 6 is provided on the side wall of the storage tank body 1. The tank door 6 is rotatably connected to the inspection port opened on the side wall of the storage tank body 1 via a set of hinges, allowing for flexible opening and closing. A handle 7 is fixedly connected to the outer side wall of the tank door 6, allowing operators to easily control the opening and closing of the tank door 6, facilitating maintenance or cleaning of the tank interior, such as removing residue from the inner tank 101 wall.

[0029] To clearly define the pipe layout, the inlet pipe 2 is located on the top right side of the storage tank body 1, and the outlet pipe 5 is located on the bottom left side of the storage tank body 1. This asymmetrical arrangement facilitates pipe design and integration, and avoids interference between pipes.

[0030] To ensure the purity of the raw materials and achieve effective heat preservation, the inner tank 101 is preferably made of ultra-low carbon stainless steel, which has excellent corrosion resistance and chemical inertness, avoiding reactions with raw materials such as perfluoropolyethers and siloxanes, thereby maximizing the purity of the raw materials. The outer tank 102 is preferably made of carbon steel, and its main function is to provide sufficient structural strength and pressure-bearing capacity to meet the stable operation requirements of the equipment.

[0031] To further emphasize the physical separation of raw materials, the partition 302 is vertically fixed to the inner wall of the hopper 301, dividing the hopper 301 into two independent chambers that are not connected to each other, ensuring that the two raw materials to be measured are completely physically isolated before entering the batching box.

[0032] To maintain stable operation of the device, the bottom of the storage tank body 1 is fixedly connected with support feet 8, preferably four support feet 8, which are distributed in a rectangular array to stably support the entire device and ensure the stability of the tank during the batching and mixing process.

[0033] Working principle: When using this equipment, firstly, the required proportions of raw materials are added to the storage tank body 1 through the batching mechanism 3. Then, the liquid inlet pipe 2, which is fixedly connected to the top of the storage tank body 1, is opened to add water into the storage tank body 1. During the batching process, the liquid level rise is observed through the observation mechanism 4 to facilitate the adjustment of the total amount of raw materials at any time. At the same time, the raw materials are kept warm through the inner tank 101 and the outer tank 102 during the batching process. After the batching is completed, the liquid outlet pipe 5, which is fixedly connected to the bottom of the storage tank body 1, is opened to discharge the material and complete the collection. At the same time, when the equipment needs to be inspected and maintained, the tank door 6 is opened through the handle 7, which is fixedly connected to the side wall of the tank door 6, to facilitate maintenance or cleaning of the inside of the storage tank body 1. During the use of the equipment, the support feet 8, which are fixedly connected to the bottom of the storage tank body 1, are used for support to maintain the stable operation of the equipment. When mixing raw materials through the mixing mechanism 3, several raw materials are first added separately into the hopper 301 separated by the partition 302. The first motor 305, which is fixedly connected to the side wall of the first mixing box 303, is started. The output end of the first motor 305 drives the first rotating fan 304, which is fixedly connected to it, to rotate in the first mixing box 303. Since the spacing between the first rotating fans 304 is fixed, the addition efficiency and total amount of the first material can be controlled by adjusting the rotation speed and the opening time. Through the rotation of the first rotating fan 304, the material in the hopper 301 is added to the storage tank body 1 through the first discharge pipe 306, which is fixedly connected to the bottom of the first mixing box 303. The same applies to the other side. The second motor 309, which is fixedly connected to the side wall of the second mixing box 307, is started so that the second motor 309 drives the second rotating fan 308 to rotate, and another material is transported to the storage tank body 1 through the second discharge pipe 310. When observing the batching process, the internal condition of the storage tank 1 can be observed through the viewing window 401 inside the storage tank body 1. Readings can be taken using the scale lines 402 on the side wall of the storage tank body 1, allowing staff to constantly monitor the batching process and make corresponding adjustments. Meanwhile, the inner tank 101 is made of ultra-low carbon stainless steel, which is corrosion-resistant and chemically inert. It will not react with perfluoropolyethers and siloxanes, ensuring the purity of the raw materials to the maximum extent. The outer layer is made of carbon steel, which does not contact the materials, meeting the requirements for pressure resistance and heat conduction.
