Description

Technical Field

[0001] This utility model relates to the field of trough mixer technology, specifically a trough mixer. Background Technology

[0002] The trough mixer is a common industrial mixing equipment, mainly used for mixing materials such as powders, granules, and liquids. Its structure is usually trough-shaped, and it has efficient stirring and mixing functions, making it suitable for multiple industries such as chemical, food, and pharmaceutical.

[0003] The existing utility model with authorization announcement number CN221832051U discloses a trough-type mixer, including a mixing box. A power module is snapped onto one side of the mixing box, and a stirring module is threaded onto one side of the power module. Support plates are snapped onto both sides of the upper end face of the mixing box. A rotating shaft is fixedly installed on the upper end face of the two support plates. Rotating plates are fixedly installed on both sides of the outer surface of the rotating shaft. The power module includes a placement box, and a partition is fixedly installed in the middle of the inner surface of the placement box.

[0004] Although the above technical solution allows the mixing box to mix feed ingredients, and the mixing box and power module are fixed together during use, and the power module and the stirring module inside the mixing box are also fixed together to enable the stirring module to operate and mix the ingredients inside the mixing box, and the upper end of the mixing box has a support plate with a rotating shaft fixed to the upper end of the support plate to allow the rotating plate to rotate, the above technical solution has the following problems during use:

[0005] This scheme mainly uses a unidirectional stirring structure to stir and mix materials. This method not only has low material mixing efficiency, but also cannot fully mix the materials.

[0006] The trough mixer has certain limitations in use. It cannot monitor and control the temperature of the mixed materials in real time. For example, in the chemical industry, many reactants need to be kept within a specific temperature range during the mixing process to promote or control the reaction rate. Too high or too low a temperature may lead to incomplete or uneven reaction.

[0007] The existing equipment mainly relies on the motor to drive the mixing drum to continuously adjust its direction and tilt the mixing drum to pour the material during the unloading process. This is not only time-consuming and labor-intensive, but also, when the mixing drum is not adjusted to the appropriate position, it is easy to cause a large amount of material to remain inside the trough mixer, thereby reducing the effectiveness of the equipment.

[0008] Therefore, those skilled in the art have provided a trough-type mixer to solve the problems mentioned in the background art. Utility Model Content

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0041] Example 1

[0042] Please see Figure 1-12A trough-type mixer includes a base plate 1. A protective box 11 and a controller body 2 are fixedly connected to the upper surface of the base plate 1. A bidirectional stirring and temperature control mechanism 3 is arranged above the base plate 1. The bidirectional stirring and temperature control mechanism 3 includes a dual-chamber stirring tank 301. A semiconductor cooling chip 303, a heating plate 315, and two temperature sensors 317 are fixedly connected to the inner wall of the dual-chamber stirring tank 301. The working principle of the semiconductor cooling chip 303 is based on the thermoelectric effect, especially the Peltier effect. When current passes through the thermoelectric chip, which is usually made of different semiconductor materials, typically a bismuth-antimony alloy, a temperature difference will occur between the two ends of the chip. One side absorbs heat, and the other side releases heat, thereby achieving a cooling effect. When current passes through, heat is transferred from one side of the cooling chip to the other side. The cold end absorbs heat, causing its temperature to drop, while the hot end releases heat, causing its temperature to rise. By adjusting the magnitude of the current, the cooling effect can be precisely controlled. The cold end of the semiconductor cooling chip 303 is in contact with the outer side of the inner wall of the dual-chamber stirring tank 301. The semiconductor cooling chip 303 generates a cooling effect that is transferred to the material inside the dual-chamber mixing tank 301 through the inner wall of the tank. The hot end of the semiconductor cooling chip 303 is in contact with the air, and the heat generated during operation is dissipated through the air. The heating plate 315 operates based on resistance heating. When current passes through the resistive material inside the heating plate 315, electrical energy is converted into heat energy, causing the surface temperature of the heating plate 315 to rise. Typically, the heating plate 315 is made of a metal material with good thermal conductivity to ensure uniform heat transfer. The temperature of the heating plate 315 can be controlled by adjusting the current to heat the equipment or environment. The heating plate 315 is connected to the outer side of the inner wall of the dual-chamber mixing tank 301. The heat generated by the heating plate 315 is transferred to the material inside the dual-chamber mixing tank 301 through the inner wall of the tank, thus heating the material.

[0044] The bidirectional stirring temperature control mechanism 3 is internally equipped with an arc-shaped switch mechanism 4. The arc-shaped switch mechanism 4 includes two U-shaped frames 404. The outer surface of each U-shaped frame 404 is fixedly connected to the inner wall of the dual-chamber stirring tank 301. A threaded rod 408 is rotatably connected to the inner wall of each U-shaped frame 404. A guide rod 406 is fixedly connected to the inner wall of each U-shaped frame 404. A sliding frame 405 is threadedly connected to the outer surface of each threaded rod 408. The interior of each sliding frame 405 is slidably connected to the outer surface of the guide rod 406. Two connecting plates 403 are movably hinged to the inner wall of each connecting plate 403. The system is hinged with arc-shaped components 401, two of which are fixedly connected to a first arc plate 409 on their outer surfaces, and two other arc-shaped components 401 are fixedly connected to a second arc plate 402 on their outer surfaces. The interior of the second arc plate 402 is engaged with the outer surface of the first arc plate 409. A rotary motor 407 is installed above each U-shaped frame 404, and the power output end of each rotary motor 407 is fixedly connected to the top of a threaded rod 408.

[0046] Two sets of support columns 7 are fixedly connected to the bottom surface of the base plate 1. Each support column 7 has a protective pad 8 fixedly connected to its bottom end. The support columns 7 and protective pads 8 work together to support and protect the device, facilitating its movement and transport, and thus improving its efficiency. The controller consists of two parts: hardware and software.

The software includes control algorithm programs, a real-time operating system (RTOS), and a human-machine interface, all working together to ensure accuracy and efficiency. The system control of this technology is widely used in industrial automation, smart homes, automotive electronics, and other fields. A controller is a core device that regulates system operation by processing input signals in real time and generating control commands. Its working principle can be summarized as follows: First, it collects signals from sensors or external inputs such as temperature and speed, compares them with preset target values ​​to calculate the deviation; then, it uses built-in algorithms such as PID control and logical judgment to analyze the deviation and generate adjustment commands; finally, it drives actuators such as motors and valves through the output interface to adjust the system state, while continuously monitoring the effect through closed-loop feedback to achieve dynamic stability. The controller can control the electrical components of this technical solution.

The bearing body 10 can be used to reinforce the threaded rod 408 and prevent the threaded rod 408 from fluctuating during rotation, thereby affecting the stability of the device.

[0050] Example 3

[0051] The working principle of this utility model is as follows: In use, the operator first connects the controller body 2, stepper motor 308, temperature sensor 317, heating plate 315, semiconductor cooling chip 303, and rotary motor 407 to the power supply. When using this device to mix materials, the second arc plate 402 and the first arc plate 409 are first locked together. The operator inputs the required temperature for material mixing into the controller body 2. Then, the movable door 302 is opened, and the materials to be mixed are put into the double-chamber mixing tank 301. The controller body 2 then controls the temperature sensor 317 to detect the temperature of the inner wall of the double-chamber mixing tank 301. The data detected by the temperature sensor 317 is transmitted to the controller body 2 via a line. After receiving the data, the controller body 2 compares it with the original data set by the operator. When the temperature is lower or higher than the set value, the controller body 2 automatically controls the heating plate 315 or semiconductor cooling chip 303 to heat or cool the inner wall of the double-chamber mixing tank 301. During this process, the temperature sensor 317 continuously detects the temperature. When the temperature reaches the set value, the controller body 2 controls the heating plate 315 or semiconductor cooling chip 303 to heat or cool the inner wall of the double-chamber mixing tank 301. When plate 303 stops working, it simultaneously controls stepper motor 308 to work. Supported by gear carrier 313 and stabilizing plate 316, stepper motor 308 drives main gear 312 to rotate. Since main gear 312 meshes with first gear 311 and second gear 310 respectively, the rotation of main gear 312 drives first gear 311 and second gear 310 to rotate in two opposite directions. The rotation of first gear 311 drives stirring shaft 306 to rotate. Stirring shaft 306 is composed of one bearing carrier 307, gear carrier 313, and the right side of gear carrier 313. The side fixing plate 309 and the protective box 11 serve as supports, rotating in the forward direction around the stirring frame 314 and the inside of the second gear 310; at the same time, the main gear 312 drives the second gear 310 to rotate, and the rotation of the second gear 310 drives the stirring frame 314 to be sleeved on the outer surface of the stirring shaft 306, and the stirring frame 314 rotates around the inner wall of the double-cavity stirring tank 301, the inner wall of the bearing frame 307 and the inner wall of the protective box 11, realizing the reverse movement of the stirring frame 314. Through the setting of the bidirectional stirring temperature control mechanism 3, the material in the double-cavity stirring tank 301 is fully stirred.

[0052] After the materials are evenly mixed, when the first arc plate 409 and the second arc plate 402 need to be opened, the operator uses the controller body 2 to control two rotary motors 407 to work simultaneously. Under the support of the U-shaped frame 404, the rotary motors 407 drive the threaded rod 408 to rotate in the forward direction. Due to the helical transmission relationship between the threaded rod 408 and the sliding frame 405, the rotational motion of the threaded rod 408 is converted into linear motion of the sliding frame 405 along the outer surface of the guide rod 406. Since the sliding frame 405 is hinged to one end of the connecting plate 403, the linear displacement of the sliding frame 405 will pull the connecting plate 403, causing the connecting plate 403 to swing. The other end of the connecting plate 403 is connected to the arc member 401 through a hinge. Therefore, the swing of the connecting plate 403 will further drive the arc member 401 to swing in an arc shape around its own hinge fulcrum within a certain range. Since the arc member 401 is fixedly connected to the first arc plate 409 and the second arc plate 402 respectively, the arc member... The swinging motion of component 401 causes the first arc plate 409 and the second arc plate 402 to swing away from each other along the double-chamber mixing tank 301. The first arc plate 409 and the second arc plate 402, which are related, move away from each other under the external force of the arc component 401. At this time, the well-mixed material falls precisely from the inside of the double-chamber mixing tank 301 into the storage box 305, achieving precise material recovery. After the material is unloaded, the rotary motor 407 is controlled to rotate in the opposite direction. Under the mechanical connection of the connecting plate 403, U-shaped frame 404, sliding frame 405, guide rod 406, and threaded rod 408, the first arc plate 409 and the second arc plate are reset, closing the first arc plate 409 and the second arc plate for future use. This device not only allows for strict detection and control of the temperature of the material inside the trough mixer and achieves bidirectional mixing of the material, ensuring thorough mixing and improving the uniformity of the mixture, but also avoids the problem of constantly adjusting the direction of the mixing drum to completely dump and recover the mixed material.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
