Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a small multifunctional mixer. Background Technology

[0002] For processing various materials in industries such as chemicals, pharmaceuticals, and food, multi-functional mixers are often used to stir, disperse, and emulsify the materials. Current equipment technology mainly focuses on mechanical stirring and modular design, but the following key issues and technical limitations still exist:

[0003] 1. High energy consumption and low power system efficiency.

[0004] Traditional mixing equipment often uses high-power AC motors or fixed-speed drives, resulting in significant energy losses. For example, metal smelting mixing devices, due to their single-speed design, cannot adjust the speed according to the viscosity of the material, leading to over-mixing or under-mixing, increasing energy consumption by 30%-50%. In addition, complex transmission system designs (such as multi-stage gear transmissions) further reduce energy utilization.

[0005] 2. The production process is not observable.

[0006] Most equipment uses metal containers, making it impossible for operators to observe the mixing status in real time. They must rely on indirect parameters (such as temperature and rotation speed) to judge the mixing effect. For example, traditional drug mixers lack transparent observation windows, causing the mixing process to rely on experience for adjustments, which affects the stability of drug quality.

[0007] 3. Large size.

[0008] Traditional equipment has low integration and complex structure. For example, metal smelting mixing devices require independent installation of cooling systems and flue gas treatment units, resulting in a large footprint. Disassembly is also necessary for transportation, increasing costs. Utility Model Content

[0009] In response to the shortcomings of the existing production technologies, the applicant provides a small, multi-functional mixer with a reasonable structure, which has the advantages of small size, intuitive and visible production process, and reduced energy consumption.

[0010] The technical solution adopted in this utility model is as follows:

[0011] A small, multi-functional mixer includes a box-type frame, one side of which is recessed to form a mixing space for holding containers; the box-type frame is provided with a top seat and a base at the top and bottom of the mixing space, respectively.

[0012] The box-type frame houses a power unit, with one power output end extending into the mixing space to drive the mixing components.

[0013] As a further improvement to the above technical solution:

[0014] The power output end of the power unit is coaxial with the stirring shaft of the stirring assembly.

[0015] The side of the top seat facing the mixing assembly serves as the positioning surface for the mixing assembly.

[0016] A geared motor is installed inside the top seat of the box-type frame. The geared motor rests on the inner bottom wall of the top seat facing the mixing assembly. The piston rod of the geared motor passes through this wall and is directly connected to the mixing shaft of the mixing assembly.

[0017] The mixing assembly includes a mixing shaft, a mixing paddle connected to the bottom of the mixing shaft, and a vacuum cover located in the middle of the mixing shaft. The vacuum cover is provided with a feed inlet and a sensor port. A shearing assembly and a dispersing assembly also pass through the vacuum cover.

[0018] The base is equipped with a lifting seat, which moves vertically back and forth based on the box-type frame, and a container is placed on the lifting seat.

[0019] The box-type frame is equipped with a screw jack, which drives the lifting seat to rise and fall.

[0020] The lifting seat includes:

[0021] The lifting frame connects to the output end of the screw jack.

[0022] The base is located on the side of the lifting frame away from the screw jack, and the container is placed on the base.

[0023] The base is equipped with slots that have the same shape as the bottom of the container;

[0024] When the container is placed in the slot of the base, the side wall of the container abuts against the concave side wall of the lifting frame.

[0025] The container is made of stainless steel or transparent acrylic.

[0026] The beneficial effects of this utility model are as follows:

[0027] The power source of this application uses a brushless DC motor, which has low power consumption and low energy consumption. Furthermore, it employs a direct-drive structure, reducing intermediate transmission components and effectively minimizing efficiency losses. The motor speed is adjustable, allowing selection of an appropriate speed based on material characteristics to avoid energy waste.

[0028] In one embodiment of this application, a transparent container made of acrylic material is used to make the entire mixing process observable, and integrated sensors monitor the material status in real time, thereby improving the controllability of the production process.

[0029] The frame is constructed using aluminum profiles, and the electrical components are integrated inside the equipment. A touch screen is mounted on the back of the transmission box cover, achieving a compact and lightweight design that reduces the weight and size of the equipment.

[0030] The biggest difference between this application and existing mixers lies in the fact that the power source is directly located on top of the mixing assembly, with the output shaft of the power source motor extending directly and connecting to the mixing shaft, without any other transmission structure in between. Based on this direct torque transmission, the transmission path is further shortened: the power source motor is located at the top, the container's lifting seat is at the bottom, and the intermediate mixing space is compressed, only allowing for the height of the container's lifting installation. The shorter the transmission path, the higher the coaxiality of the shaft, and the lower the energy consumption. Furthermore, the top seat and base are integrated with the frame, resulting in higher overall strength and a more stable center of gravity. Conventional motor installations often extend above the container, resulting in a small installation area. During mixing, the motor position is prone to loosening and displacement due to stress. The top seat in this application has a large area and is integrated with the frame, effectively providing the motor with a larger and more stable protective installation platform. This improves the stability of the power source, further ensures the coaxiality of the mixing shaft, and guarantees the reliability of the mixing action. Attached Figure Description

[0040] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0041] like Figures 1-5 As shown, the small multi-functional mixer of this embodiment includes a box-type frame 1, one side of which is recessed to form a mixing space 101 for holding a container 6; the box-type frame 1 is provided with a top seat 102 and a base 3 at the top and bottom of the mixing space 101, respectively.

[0042] The housing frame 1 houses a power unit, one of whose power output ends extends into the mixing space 101 and is connected to the mixing assembly 4. The top seat 102, facing the mixing assembly 4, serves as the positioning surface 103 for the mixing assembly 4.

[0043] The power unit directly drives the stirring assembly 4, and the power output end of the power unit is coaxial with the stirring shaft 401 of the stirring assembly 4.

[0044] A geared motor 5 is installed inside the top seat 102 of the box-type frame 1. The geared motor 5 rests on the inner bottom wall of the top seat 102 facing the stirring assembly 4. The piston rod of the geared motor 5 passes through this wall and is directly connected to the stirring shaft 401 of the stirring assembly 4. The geared motor 5 is built into the top seat 102, and the positioning surface of the top seat 102 facing the stirring assembly 4 is the mounting surface of the geared motor 5. With the stirring assembly 4 as the orientation reference, the geared motor 5 is located on the back of the positioning surface.

[0045] The height of stirring component 4 is constant.

[0046] The stirring assembly 4 includes a stirring shaft 401, a stirring paddle 402 connected to the bottom of the stirring shaft 401, and a vacuum cover 403 located in the middle of the stirring shaft 401. The vacuum cover 403 is provided with a feed inlet and a sensor port. A shearing assembly 404 and a dispersing assembly 405 also pass through the vacuum cover 403.

[0047] The lifting seat 7 is based on the box-type frame 1 and moves vertically back and forth. The lifting seat 7 is equipped with a container 6.

[0048] The box-type frame 1 is equipped with a screw jack 2, which drives the lifting seat 7 to rise and fall.

[0049] Lifting seat 7 includes:

[0050] The lifting frame 701 is connected to the output end of the screw jack 2.

[0051] The base 702 is located on the side of the lifting frame 701 away from the screw jack 2, and the container 6 is placed on the base 702.

[0052] The bottom support 702 has the same shape as the bottom of the container 6 and is coaxial.

[0053] When container 6 is placed on base 702, the side wall of container 6 abuts against the concave side wall of lifting frame 701.

[0054] Container 6 is made of stainless steel or transparent acrylic.

[0055] The specific structure and working principle of this application are as follows:

[0056] To address the problems of high energy consumption, lack of process monitoring, and large size associated with traditional multi-functional mixing equipment, this application provides a small multi-functional mixer that effectively solves these issues.

[0057] like Figure 1 and Figure 2 As shown, a small multi-functional mixer includes a box-type frame 1, such as Figure 2 The side of the box-type frame 1 shown is recessed to form a mixing space 101. The mixing space 101 is used to accommodate the mixing components 4 and the container 6. The advantage of this arrangement is that the overall size of the box-type frame 1 is large, while the space occupied by the mixing space 101 is relatively small. Since the box-type frame 1 also contains structures such as a power source and counterweights, the stability of the entire machine is guaranteed.

[0058] The box-type frame 1 includes a top seat 102, which is located directly above the mixing space 101. Within the top seat 102, such as... Figure 2 In the center position, a geared motor 5 is provided as the power source to drive the stirring assembly 4. The output shaft of the geared motor 5 passes directly through the bottom wall of the top seat 102 and is connected to the stirring paddle 402, without any other transmission structure, in order to reduce the loss during the transmission process. In addition, since the top seat 102 also compensates for the height of the frame, the output shaft of the geared motor 5 can be relatively shorter, further ensuring the coaxiality of the stirring paddle 402.

[0059] With the stirring component 4 as the orientation reference, the bottom wall of the top seat 102 faces away from the back of the stirring component 4 and is the mounting surface of the geared motor 5; the bottom wall of the top seat 102 faces the front of the stirring component 4 and is the positioning reference of the stirring component 4. Compared with the small area structure of the stirring paddle 402 in conventional products, the large area positioning surface 103 of this application can provide higher stability.

[0060] The mixing assembly 4 can use any commercially available mixing paddle 402. The box-type frame 1 provided in this application is suitable for various small-sized mixing paddles 402. It is recommended to choose a small-sized mixing paddle 402 because this application is aimed at small mixers.

[0061] like Figures 3-4 As shown, the lifting seat 7 in this application is a movable structure capable of vertical up-and-down movement. (Refer to reference...) Figure 2 In this application, a screw jack 2 is used to drive the lifting seat 7 to move up and down. When the screw jack 2 lifts the container 6, the container 6 and the vacuum cover 403 are closed. After the stirring is completed, the screw jack 2 drives the lifting seat 7 and the container 6 to reset.

[0062] In one embodiment of this application, considering that many materials in the chemical and pharmaceutical industries are highly corrosive, conventional mixing equipment is easily damaged by corrosion, affecting product quality and equipment lifespan. This embodiment addresses this specific need by comprehensively improving the corrosion resistance of the aforementioned basic structure.

[0063] All parts that come into contact with materials are made of 316L stainless steel, which contains 2-3% molybdenum and has better resistance to chloride corrosion than 304 stainless steel.

[0064] The stirring frame, dispersion disc, and rotor surfaces of the agitator 402 undergo double-layer treatment:

[0065] Substrate: Electrochemically polished to Ra≤0.2μm,

[0066] Surface layer: Spray a 50-80μm thick ETFE (ethylene-tetrafluoroethylene copolymer) coating.

[0067] All bushings used have been upgraded from the standard PTFE material to PTFE with 25% glass fiber reinforcement.

[0068] The feed port, temperature measuring port and other interfaces are lined with PTFE sleeves.

[0069] This embodiment optimizes the basic mixing equipment through material selection and surface treatment, giving it excellent corrosion resistance. It is particularly suitable for fields with strict requirements on equipment corrosion resistance, such as pharmaceuticals, fine chemicals, and electronic chemicals.
