Description

Technical Field

[0001] This utility model relates to the field of equipment for mixing and stirring raw materials, specifically a powder raw material dissolving, mixing and stirring device with anti-agglomeration function. Background Technology

[0002] In many practical applications and work scenarios, it is necessary to mix solid and liquid components in different states to obtain specific final products. For example, in the chemical production field, fine chemicals use the mixture of pigment powder and liquids such as resin solutions to synthesize dyes, pigments, fragrances, and coatings. In the daily chemical industry, surfactant powders are mixed with water, humectants, and fragrances in the production of cosmetics, detergents, and toothpaste. In the pharmaceutical industry, drug powders are mixed with binder solutions to prepare tablets, capsules, and other drug formulations. In pharmaceutical research and development, this is used for experiments such as drug solubility and stability studies. In food processing, beverage production involves mixing solid raw materials such as sugar and flavorings with liquids such as water and fruit juice; baking involves mixing flour with liquid raw materials such as water, oil, and yeast. Furthermore, in the research and production of new materials, solid particles need to be mixed with resin solutions to ensure uniform dispersion during the preparation of composite materials; high-performance ceramic powders are prepared by mixing ceramic powders with liquid additives such as binders; and in the production of electronic materials, positive and negative electrode material powders need to be mixed with binder solutions for the preparation of lithium battery electrode materials. In order to ensure the uniformity of mixing and dispersion of solid powders and liquid components such as solvents, various stirring and mixing devices are often used.

[0003] Existing mixing devices can mix and stir powdered raw materials and solvents of various components according to different actual application scenarios or processing and production needs, so as to obtain solutions or liquid mixtures with high dispersion and uniformity of components. For example, a dissolving and mixing device for adhesive production disclosed in Chinese invention patent application CN202510144535.4 includes a mixing tank, a pulverizing component, a premixing cylinder, a first stirring component, and a second stirring component. The present invention uses the pulverizing component to pre-pulverize the solid material before mixing it with the liquid raw material in the mixing tank. The premixing cylinder can pre-mix the liquid raw material and diffuse it out of the premixing cylinder through the diffusion holes. The first stirring component in the premixing cylinder stirs the solution in the premixing cylinder, which can enhance the stirring effect of the solution in the premixing cylinder. The first stirring rod on the alternating upper and lower stirring rods and the second stirring rod on the rotating shaft can generate superimposed stirring forces during the stirring process, which can further enhance the stirring intensity. This allows the solid powder material to be subjected to stronger shearing and collision effects during the stirring process, avoiding the formation of agglomerates and clumps, and improving the efficiency and quality of dissolution and mixing of solid materials and liquid raw materials. For example, Chinese utility model patent application CN202020018937.2 discloses a pneumatic stirring type dissolving and preparation device for traditional Chinese medicine powder, including a tank and a cover plate. The upper end of the tank has an opening, and the lower end of the cover plate is fixedly connected to an annular block, which slides and fits into the upper opening of the tank. The upper end of the cover plate is fixedly connected to a feeding hopper, and the lower end of the feeding hopper is fixedly connected to a feeding pipe. The lower end of the feeding pipe penetrates the side wall of the cover plate and extends into the tank. The lower end of the feeding pipe is fixedly connected to an arc-shaped baffle, and the lower left side of the baffle is fixedly connected to a distributing plate. The upper end of the distributing plate has a distributing groove, and the bottom of the distributing groove has multiple guiding grooves. This utility model can uniformly add traditional Chinese medicine powder to water, avoiding powder clumping during preparation, and can fully mix the medicine, making the prepared medicine less prone to segregation and stratification, and easier for patients to drink.

[0004] However, the applicant discovered that in the aforementioned production scenarios where powdered raw materials are added to solvents for mixing and dissolution, the actual addition ratio and rate are difficult to control when mixing materials of different components. This is especially true when mixing powdered solid additives with solvents or liquid components, which easily leads to agglomeration. These small, granular clumps continuously circulate with the solution under the agitation of the device. The mixing and stirring devices described in the above solution only have conventional agitation and mixing functions and cannot specifically eliminate these small clumps remaining in the liquid product. This results in two problems: firstly, clogged discharge pipes reducing discharge efficiency; and secondly, product accumulation in certain areas within the stirring device, causing the proportions of various components in the filtered liquid product to deviate from the theoretical preset, affecting the subsequent use of the product.

[0005] To address the aforementioned problems, this utility model provides a powder raw material dissolving, mixing, and stirring device with anti-agglomeration function. It can sieve and filter out small clumps formed during the mixing and dissolving process of powder raw materials and the liquid to be added. Through the continuous flow circulation formed by the solution section inside the device, these sieved clumps are broken up and eliminated, allowing the final solution composition ratio and mixing uniformity to be closer to the expected state, thereby improving the product quality of the obtained mixed solution.

[0027] The following specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.

[0028] This solution is achieved through the following technical means:

[0029] Example: In this example, a powder raw material dissolving, mixing and stirring device with anti-agglomeration function is provided. It can screen out the small clumps formed during the mixing and dissolving of powder raw materials and the liquid to be added, and through the continuous flow circulation formed by the solution inside the device, the clumps are broken up and eliminated, so that the final solution composition ratio and mixing uniformity are closer to the expected state, thereby improving the product quality of the obtained mixed solution.

[0030] Specifically, the structure of the powder raw material dissolving, mixing, and stirring device with anti-agglomeration function given in this patent application can be referred to the appendix to the specification. Figure 1The overall structural layout of the device is illustrated below. The device includes a main body 1 with a hollow mixing chamber 101 and a circulation guide channel 102. In this embodiment, the circulation guide channel 102 is positioned on the side of the mixing chamber 101, with its lower end connected to the lower part of the mixing chamber 101 and its upper end connected to the upper part. Inside the mixing chamber 101, a spiral blade 2 is provided to continuously push the liquid portion downwards. A crushing and screening screen 3 is located below the spiral blade 2 within the mixing chamber 101. To achieve this structure, a motor 5 can be installed at the top of the main body 1 as a drive device. The motor's rotary output shaft drives the rotary shaft with the spiral blade 2 via a bevel gear meshing structure. When the motor 5 is energized, it drives the spiral blade 2 to rotate continuously. It should be noted that before starting the drive unit 5, the aforementioned mixing chamber 101 is already filled with a liquid solvent or various liquid raw material components. Inside the main body 1 of the device, there is an additive filling channel 103 that extends from the outside to the top of the mixing chamber 101. The main function of this additive filling channel 103 is to add various powdered additives to the mixing chamber 101, which stores the liquid raw materials. (See attached instruction manual) Figure 2 Taking the structure shown as an example, the crushing and screening screen plate 3 mainly includes a high-strength mesh material layer 301 located in the middle and a main frame portion 302 surrounding the outer side of the material layer. For example, the high-strength mesh material layer 301 can be formed by interlacing nylon yarns, which ensures that it has a large number of pores to allow the coating material to pass through, while also having sufficient strength to block clumps of additive materials.

[0031] To more clearly illustrate the working principle of the device, this embodiment uses the most common scenario of adjusting the color or gloss of coating materials as an example for comparison and explanation.

[0032] Conventional coating material mixing devices, when mixing base coating materials and powdered dyes, continuously agitate the base coating material while adding the dye. However, due to the difficulty in controlling the addition rate and instantaneous amount, it is easy to add too much dye to the base coating material in a short period. In this case, the liquid base coating material will first combine with the outer surface of the powdered dye, forming a relatively dense coating layer and thus a clump structure. Once this occurs, it will prevent the internal powdered dye from dispersing outwards, and it will also prevent the outer base coating material from penetrating inwards and continuing to combine and react with the powdered dye at the center of the clump, thereby reducing the uniformity of the coating material mixing. Because conventional mixing devices typically only use blade-like structures to agitate all coating materials as a whole, small clumps of additive raw materials will continue to circulate with the external fluid coating materials and cannot be eliminated. This results in the final coating material still containing small clumps or particles, greatly reducing the quality of the coating material.

[0033] To address the problems arising from the aforementioned situation, the powder raw material dissolving, mixing, and stirring device with anti-agglomeration function provided in this application incorporates a structure in which a spiral blade 2 and a crushing and screening screen 3 work together. Similar to the aforementioned conventional stirring and mixing devices, this device, when initially adding solid powdered components such as powdered dyes as additives to water or liquid components, achieves initial dispersion and mixing through the continuous agitation of the spiral blade 2. However, it inevitably forms small agglomerated structures in the coating material. At this time, as the aforementioned spiral blade 2 continues to rotate, it continuously pushes the liquid coating material downwards. This portion of the liquid coating material passes through the crushing and screening screen 3 and enters the circulation channel 102 from below the mixing chamber 101. It then re-enters the mixing chamber 101 from the upper part of the circulation channel 102, thus forming a flow circulation within the device. At this point, the clump-like or granular additive components initially flow with the liquid coating material. Because their particle size is larger than the pores in the crushing and screening screen 3, they are confined and adhere to the screen. As the coating material continues to circulate under the propulsion of the spiral blades 2 and continuously impacts these small clumps, a compressive force is applied. With continued agitation, the clump-like additive material eventually breaks down and disperses until it can pass through the pores formed in the crushing and screening screen 3. Ultimately, the size of all fine particles or clumps in the final coating material is controlled below the size of the pores.

[0034] As a preferred structure, in this embodiment, the crushing and screening screen plate 3 is arranged at an angle within the mixing chamber 101, and the higher side of the crushing and screening screen plate 3 is opposite to the spiral blade 2. Refer to the appendix of the specification for further details. Figure 3 As shown in the structure, when the aforementioned clump-like or granular additive material components initially adhere to the higher side of the crushing and screening screen plate 3, the clump-like additive material components will roll downwards along the surface of the screen plate as the coating material circulates. Compared to a screen plate that is horizontally arranged, this structure adds a downward rolling process to the clump-like structures during the operation of the mixing device. At this time, for these larger clump-like parts, some of them will first embed themselves into the pores of the crushing and screening screen plate 3. As the clump-like parts roll along the screen plate, these embedded parts will be peeled off from the main body of the clump, thereby gradually breaking down and eliminating these clump-like structures until they become particles with the required size that can flow through the aforementioned crushing and screening screen plate 3 with the liquid portion, thus improving the overall processing effect of the mixing device.

[0035] Of course, the mixing and stirring method for coating materials mentioned here is just one common application scenario for mixing powder raw materials with liquid components. This device can also be widely used in various practical fields such as medical and chemical industries. Therefore, the aforementioned working method should not be regarded as a limitation of this mixing and stirring device.

[0036] Further preferably, to facilitate smoother circulation within the mixing device, an arc-shaped transition section 1021 can be formed within the circulation guide channel 102, and an inclined guide surface 1011 inclined towards the bottom of the circulation guide channel 102 can be provided at the bottom of the mixing chamber 101. On the other hand, to reduce the obstruction of the coating material flow at the connection point when the two ends of the crushing and screening screen plate 3 are respectively mounted and fixed on the inner wall of the mixing chamber 101, a guide transition portion 4 can also be formed between the crushing and screening screen plate 3 and the inner wall of the mixing chamber 101. This guide transition portion 4 has an inclined surface extending from the inner wall of the mixing chamber 101 towards the high-strength mesh material layer 301 on the crushing and screening screen plate 3.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
