Description

Technical Field

[0001] This utility model relates to the field of mixing devices, and in particular to a mixing device for the production of plant fiber raw materials. Background Technology

[0002] Plant fiber raw materials are essential basic materials for industries such as papermaking and textiles, with wood pulp being one of the most common. The production process of wood pulp typically involves mixing wood chips with chemical solutions (such as cooking liquor) to ensure the solution penetrates evenly into the wood chips, thereby effectively separating the fibers during the subsequent cooking process. Traditional mixing devices often employ simple agitator structures, using mechanical stirring to mix the wood chips and the solution. However, this mixing method has significant drawbacks: firstly, relying solely on the shear force of the agitator makes it difficult for the solution to penetrate the wood chips quickly and evenly, resulting in low mixing efficiency; secondly, the slow penetration rate of the solution prolongs the production cycle, increases energy consumption, and may even affect the final quality of the wood pulp due to incomplete local reactions. Therefore, there is an urgent need for a mixing device for the production of plant fiber raw materials to solve these problems. Utility Model Content

[0003] The main objective of this invention is to provide a mixing device for the production of plant fiber raw materials, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A mixing device for producing plant fiber raw materials includes a mixing container. A first support is fixedly installed on the upper inner wall of the mixing container, and a second support is fixedly installed on the upper outer wall of the mixing container. A heating and stirring assembly for mixing and heating the raw materials is rotatably installed on the first support. The heating and stirring assembly consists of a support pipe, a heat-insulating connecting pipe, a heating pipe, mixing blades, a heat-conducting plate, and a heating rod. The heat-insulating connecting pipe is fixedly installed at the lower end of the support pipe, the heating pipe is fixedly installed at the lower end of the heat-insulating connecting pipe, the mixing blades are fixedly sleeved on the heating pipe, the heat-conducting plate is fixedly installed on the outer wall of the heating pipe, and the heating rod is movably placed inside the heating pipe. A drive assembly is fixedly installed on the second support and the heating and stirring assembly.

[0006] Preferably, the supporting pipe on the heating and stirring assembly is rotatably mounted on the first bracket, and the heat-insulating connecting pipe is located below the first bracket.

[0007] Preferably, there are two sets of mixing blades, both of which are fixedly connected to the heating pipe by welding. There are several heat-conducting plates that are welded in a ring on the heating pipe. The heat-conducting plates are located between the two sets of mixing blades. A power cord is fixedly connected to the heating rod and passes through the support pipe and the heat-insulating connection pipe.

[0008] Preferably, the drive assembly consists of a servo motor, a drive pulley, a transmission pulley, and a connecting belt.

[0009] Preferably, the servo motor is fixedly mounted on the lower end of the second bracket, the output shaft of the servo motor passes upward through the second bracket, the drive pulley is fixedly sleeved on the output shaft of the servo motor, and the drive pulley is also located above the second bracket.

[0010] Preferably, the transmission pulley is fixedly sleeved on the support pipe, and the transmission pulley is also located above the first bracket. The drive pulley and the transmission pulley are connected by a connecting belt.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

The heating rod evenly transfers heat to the heating pipe and mixing blades through the heat-conducting plate, so that the liquid medicine is heated during the stirring process, reducing its viscosity and accelerating molecular motion, thereby promoting the rapid penetration of the liquid medicine into the wood chips. This method of simultaneous heating and stirring not only solves the problem of uneven penetration caused by simple mechanical stirring in traditional mixing devices, but also shortens the production cycle and reduces energy consumption. In addition, the design of the heat-insulated connecting pipe effectively prevents heat transfer to the support pipe, ensuring that the drive assembly operates stably in a normal temperature environment and extending the service life of the device. The overall structure is simple and practical, significantly improving the mixing effect of wood chips and liquid medicine and production efficiency. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a mixing device for producing plant fiber raw materials includes a mixing container 1. A first support 2 is fixedly installed on the upper inner wall of the mixing container 1, and a second support 3 is fixedly installed on the upper outer wall of the mixing container 1. A heating and stirring assembly 5 for mixing and heating the raw materials is rotatably installed on the first support 2. The heating and stirring assembly 5 consists of a support pipe 10, a heat-insulating connecting pipe 11, a heating pipe 12, mixing blades 13, heat-conducting plates 14, and a heating rod 15. The heat-insulating connecting pipe 11 is fixedly installed at the lower end of the support pipe 10, and the heating pipe 12 is fixedly installed at the lower end of the heat-insulating connecting pipe 11. The mixing blades 13 are fixedly sleeved on the heating pipe 12, the heat-conducting plates 14 are fixedly installed on the outer wall of the heating pipe 12, and the heating rod 15 is movably placed inside the heating pipe 12. A drive assembly 4 is fixedly installed on the second support 3 and the heating and stirring assembly 5. The drive assembly 4 consists of a servo motor 6, a drive pulley 7, a transmission pulley 8, and a connecting belt 9. The servo motor 6 is fixedly installed at the lower end of the second support 3, and the output axis of the servo motor 6 passes upward through the second support 3. The drive pulley 7 is fixedly mounted on the output shaft of the servo motor 6 and is also located above the second bracket 3. The transmission pulley 8 is fixedly mounted on the support pipe 10 and is also located above the first bracket 2. The drive pulley 7 and the transmission pulley 8 are connected by a connecting belt 9. In use, the mixing container 1 needs to be installed and fixed in the designated position, and the power cord 16 installed on the heating rod 15 needs to be connected to the external temperature control system. When mixing wood chips and chemical solution, put the wood chips and chemical solution into the mixing container 1, and then start the servo motor 6. The servo motor 6 drives the support pipe 10 to rotate via the drive pulley 7, connecting belt 9, and transmission pulley 8. The support pipe 10 drives the heating pipe 12 and mixing blades 13 to rotate via the heat-insulating connecting pipe 11. The mixing blades 13 stir the raw materials, while the heating rod 15 is energized and heats up. The heat is transferred to the heat-conducting plate 14 and mixing blades 13 through the heating pipe 12, thereby heating the raw materials and promoting the penetration of the medicine into the wood chips. After stirring and heating are completed, the servo motor 6 and heating rod 15 are turned off, and the mixed raw materials are taken out.

[0020] Specifically, the support pipe 10 on the heating and stirring assembly 5 is rotatably mounted on the first bracket 2, the heat-insulating connecting pipe 11 is located below the first bracket 2, there are two sets of mixing blades 13, both of which are fixedly connected to the heating pipe 12 by welding, there are several heat-conducting plates 14 welded in a ring shape to the heating pipe 12, and the several heat-conducting plates 14 are located between the two sets of mixing blades 13, a power cord 16 is fixedly connected to the heating rod 15, the power cord 16 passes through the support pipe 10 and the heat-insulating connecting pipe 11, the support pipe 10 is rotatably mounted on the first bracket 2 by bearings to ensure stable rotation; the heat-insulating connecting pipe 11 adopts... Made of high-temperature resistant ceramic fiber material, it effectively blocks the upward conduction of heat from the heating pipe 12; the heating pipe 12 is a stainless steel hollow tube with a heating rod 15 inside, and multiple heat-conducting plates 14 are uniformly welded to the outer wall to increase the heat exchange area; the mixing blades 13 are made of two sets of spiral blades symmetrically welded on the heating pipe 12; the heat-conducting plates 14 are arranged in a radial ring to ensure that heat is evenly diffused to the liquid medicine; the heating rod 15 is a detachable electric heating element, which is connected to an external temperature control system through a power cord 16 to achieve precise temperature control. This design optimizes heat conduction efficiency while ensuring efficient mixing, and ensures the reliability of equipment operation and ease of maintenance.

[0021] Furthermore, due to the limitation of the power cord 16, the heating rod 15 remains stationary and does not rotate with the heating pipe 12, while the heating pipe 12, mixing blades 13 and heat-conducting plates 14 rotate synchronously under the drive of the drive assembly 4. This design ensures the continuous and stable heating function and avoids the power cord 16 from being entangled and damaged due to rotation. The heating rod 15 and the rotating heating pipe 12 adopt a sliding contact conductive structure or achieve power transmission through a non-rotating terminal, thereby establishing a reliable heat conduction mechanism between static heating and rotating stirring.

[0022] Finally, by installing a heating and stirring assembly 5, consisting of a support pipe 10, a heat-insulating connecting pipe 11, a heating pipe 12, a mixing blade 13, a heat-conducting plate 14, and a heating rod 15, on the first support 2 installed on the inner wall of the mixing container 1, and cooperating with the drive assembly 4, the mixing efficiency and uniformity can be significantly improved. The heating rod 15 evenly transfers heat to the heating pipe 12 and the mixing blade 13 through the heat-conducting plate 14, so that the medicine is heated during the stirring process, reducing its viscosity and accelerating molecular motion, thereby promoting the rapid penetration of the medicine into the wood chips. This method of simultaneous heating and stirring not only solves the problem of uneven penetration caused by simple mechanical stirring in traditional mixing devices, but also shortens the production cycle and reduces energy consumption. In addition, the design of the heat-insulating connecting pipe 11 effectively prevents heat from being transferred to the support pipe 10, ensuring that the drive assembly 4 operates stably in a normal temperature environment and extending the service life of the device. The overall structure is simple and practical, significantly improving the mixing effect and production efficiency of wood chips and medicine.

[0023] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
