Description

Technical Field

[0001] This utility model relates to a wet mixer and belongs to the field of powder material mixing technology. Background Technology

[0002] When mixing materials, industrial granulators or wet mixers typically add a predetermined amount of material into the equipment first, and then gradually mix the powdered material by supplying liquid. In industrial applications, when mixing black tea powder and glycerin to prepare health products, due to the high viscosity of glycerin, the above method can easily lead to localized particle adhesion during mixing, resulting in insufficient dilution and a phenomenon where some parts are still relatively dry while others are still sticky. If a one-time pour of the mixture or binder is used, some parts may be difficult to stir, leading to a longer equipment working time. If an intermittent liquid supply mixing method is used, it can also easily lead to a longer actual mixing time, and it is easy to misjudge the actual amount of glycerin used during the mixing process, making it difficult to quickly, accurately, and effectively achieve a better mixing effect. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a wet mixer for adding glycerin simultaneously with powdered materials. By utilizing the counteracting effect of the two materials, more uniform wetting is achieved before mixing, which helps to shorten the material mixing time and quickly improve the uniformity of material mixing.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] This utility model provides a wet mixer, including a mixing container. A stirring mechanism is rotatably installed inside the mixing container. A driving device for driving the stirring mechanism to rotate is provided on the mixing container. A top cover is provided on the top cover, and an exhaust pipe, a feeding pipe, and a spray pipe connected to the inner cavity of the mixing container are installed on the top cover. A diffuser plate is installed on one side of the top cover inside the mixing container. The diffuser plate is located below the feeding pipe and is inclined to the horizontal plane. A nozzle is installed on the part of the spray pipe inside the mixing container, and the nozzle points to the opening position of the diffuser plate in the downward direction.

[0006] Specifically, the diffuser plate has a trapezoidal shape that is narrower at the top and wider at the bottom, and the two sides of the diffuser plate are provided with baffles to prevent material from falling out from the sides of the diffuser plate.

[0007] Specifically, an air jet pipe connected to the inner cavity of the mixing container is installed above the mixing container, and an air nozzle is installed below the air jet pipe, with the air nozzle blowing in the direction of the opening of the diffuser plate at an angle downwards.

[0008] Specifically, the nozzle has an air chamber inside, which is connected to the jet pipe. The bottom of the nozzle has an air slit that is connected to the air chamber, and the extension direction of the air slit is parallel to the bottom plane of the diffuser plate.

[0009] Specifically, the jet pipe is located between the feed pipe and the spray pipe, and the air blowing direction of the air slit is between the nozzle's ejection position and the bottom edge of the diffuser plate.

[0010] Specifically, the mixing container has a bottom plate installed inside, the stirring part of the stirring mechanism is located above the bottom plate, and the mixing container is also equipped with a heating device for heating the bottom plate.

[0011] Specifically, the heating device includes an electric heating tube for heating the base plate, which is inserted into the base plate or coiled at the bottom of the base plate.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0013] This invention utilizes a diffusion plate structure inside the mixing container to disperse powdered materials upon input. Pre-mixing is achieved by spraying a mixture or adhesive onto the surface of the dispersed material using a nozzle. This rapidly improves the uniformity of liquid distribution. For adhesives with high viscosity at low temperatures, such as glycerin, it also quickly improves the uniformity of glycerin distribution in the powdered material and achieves initial mixing. This facilitates rapid mixing of powdered materials in subsequent mixers. Compared to traditional methods, it allows for faster assessment of the appropriate amount of adhesive, contributing to the rapid and accurate production of standardized products.

[0021] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0022] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example:

[0024] This utility model provides a wet mixer for simultaneously adding glycerin to powdered materials. The opposing action of the two materials achieves more uniform wetting before mixing, which helps shorten mixing time and quickly improves the uniformity of material mixing. To realize the structural function of the device, it includes a mixing container 1 to provide an environment for mixing powdered materials and liquids. To achieve the stirring function, a stirring mechanism 2 is rotatably installed inside the mixing container 1, and a drive device 3 is provided on the mixing container 1 to drive the stirring mechanism 2 to rotate. The drive device 3 can be a motor. The stirring mechanism 2 needs to include at least multiple blades, connected by a transmission shaft. The linkage between the mixing container 1 and the mixing container 1 should be configured with a rotary seal. To achieve pre-mixing of materials before stirring, a top cover 4 is provided on the top of the mixing container 1. An extraction pipe 5, a feeding pipe 6, and a spray pipe 8, all connected to the inner cavity of the mixing container 1, are installed on the top cover 4. The extraction pipe 5 is used to create a vacuum inside the mixing container 1, thereby attracting the material inside the feeding pipe 6 into the mixing container 1. If the material drawn into the equipment is directly sprayed with viscous liquid, not only is the direction difficult to control, but it is also difficult to evenly spray the mixed viscous liquid at different locations. Therefore, a diffuser plate 7 is installed on the side of the top cover 4 located inside the mixing container 1, as shown in the reference. Figure 3 As shown, specifically, the diffuser plate 7 is positioned below the feed pipe 6 and is inclined to the horizontal plane. When the material flows downwards from the feed pipe 6, it is blocked by the diffuser plate 7, allowing the material to spread and fall. At this time, a nozzle 9 is installed in the part of the spray pipe 8 inside the mixing container 1 to supply the corresponding adhesive. The nozzle 9 is positioned so that it points towards the downward-sloping opening of the diffuser plate 7. Figure 3 As shown, the spread material flows into the mixing container 1 from below the diffuser plate 7. When the nozzle 9 supplies the adhesive, it directly and evenly sprays the adhesive onto the surface of the material, thereby quickly achieving pre-mixing. This method can quickly and evenly mix the adhesive and powdered material. A secondary mixing process is then performed through stirring, effectively improving mixing efficiency. For adhesives with high viscosity, such as glycerin, this method can achieve excellent mixing results efficiently. Considering that the material falls through the diffuser plate 7 on a flat surface with a certain length, at least one nozzle 9 can be provided, evenly distributed along the width of the falling material.

[0025] This utility model provides a wet mixer. To improve the falling direction and position of the material, the bottom surface of the diffuser plate 7 is trapezoidal, narrower at the top and wider at the bottom. To prevent the material from falling off the side of the diffuser plate 7 and thus preventing the material from being sprayed with adhesive, baffles are provided on both sides of the diffuser plate 7 to prevent the material from falling off the side of the diffuser plate 7 and to constrain the discharge direction of the material. As a further preferred embodiment, corresponding guide sections or guide grooves (not shown in the figure) can also be provided on the bottom surface of the diffuser plate 7 to guide the powder material to be evenly distributed. Other specific embodiments are not limited here.

[0026] This utility model provides a wet mixer, specifically offering another implementation method for guiding the uniform spreading of powdered materials. Specifically, an air jet pipe 10, communicating with the inner cavity of the mixing container 1, is installed above the mixing container 1. Figure 3 As shown, an air nozzle 11 is installed below the jet pipe 10, and the air blowing direction of the air nozzle 11 is set to point towards the opening position of the diffuser plate 7 at an angle downward. Materials affected solely by gravity or impact may tend to concentrate locally on the diffuser plate 7. To reduce this tendency, other airflows are used to guide or apply force to change this tendency, so that the airflow from the jet pipe 10 can improve the uniform distribution of the material during its descent. In a preferred embodiment, an air chamber is provided inside the air nozzle 11, and the air chamber is connected to the jet pipe 10. An air slit is provided at the bottom of the air nozzle 11, communicating with the air chamber. The extension direction of the air slit is parallel to the bottom plane of the diffuser plate 7, so that the blown airflow can evenly affect the material under the influence of the airflow force. Simultaneously, the jet pipe 10 can also be positioned between the feed pipe 6 and the spray pipe 8, and as shown... Figure 3 As shown, the airflow direction of the air slit is set between the spray position of the nozzle 9 and the bottom edge of the diffuser plate 7. This method utilizes the principle of low pressure at the high-speed airflow position, which easily adsorbs powdery materials at the side position and flows them towards the airflow position, ultimately delivering the material to the spray position of the nozzle 9. It should be noted that the material supply and airflow supply occur simultaneously, but in order to maintain the low-pressure environment for material extraction in the mixing container 1, the flow rate of the airflow ejected by the air nozzle 11 per unit time should be much less than the flow rate of the airflow drawn out by the suction pipe 5, until the negative pressure environment is balanced, and the air volume of the two can be kept in equilibrium.

[0027] This utility model provides a wet mixer for mixing black tea powder and glycerin. For glycerin, a material with high viscosity at low temperatures, it is difficult to dilute and fully mix it. Therefore, a base plate 12 is installed inside the mixing container 1, and the stirring part of the stirring mechanism 2 is located above the base plate 12. A heating device 13 is also provided inside the mixing container 1 to heat the base plate 12, thereby heating the material above the base plate 12. This reduces the viscosity of the glycerin during mixing, ensuring thorough dilution and avoiding waste of glycerin and affecting the viscosity of the product. The heating device 13 may include an electric heating element for heating the base plate 12. The heating element can be directly mounted on the base plate 12 for heat conduction or coiled at the bottom of the base plate 12, allowing for both localized and global heating. When global heating is used, the heating element can be designed in an involute spiral shape to ensure uniform heating of all parts of the base plate 12.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
