Description

Technical Field

[0001] The invention relates to the technical field of dryers, in particular to an extruder which can assist in keeping raw materials dry. Background Art

[0002] In a Chinese patent with the patent publication number CN213238325U, a drying device for an extruder is disclosed, including a feed barrel, a feed pipe and a blower. The feed barrel is used to add materials. The feed pipe is connected to the bottom end of the feed barrel, and the axis of the feed pipe is set at an angle with the axis of the feed barrel; the end of the feed pipe is provided with an air outlet and a feed port located below the air outlet; the feed port is connected to the extruder; and a heating plate is fixed on the feed pipe. The blower is arranged at the end of the feed pipe away from the air outlet; the blower is used to cooperate with the heating plate to dry the material by conveying gas into the feed pipe. The wind blown in by the blower of the drying device for an extruder provided by the utility model cooperates with the heating plate to purge the material, thereby accelerating the evaporation of moisture on the material, ensuring that the material is dried when entering the extruder, and the generated water vapor is discharged from the air outlet, ensuring the drying of the material and the quality of the final product.

[0003] However, the following defects still exist in the specific use of the comparative documents:

[0004] 1. Although the materials can be dried by using a blower in combination with a heating plate in the reference document, the evaporated water vapor is directly discharged into the air. This design not only wastes energy, but also requires a separate heating device for heating. Compared with traditional heating methods, the operation of this system depends on independent heating equipment, which may be more significant in terms of power consumption than some traditional heating methods. In addition, the reference document mainly relies on the process of converting electrical energy into thermal energy, which increases the operating cost to a certain extent.

[0005] 2. In the comparative documents, when the material is dried, only the heating plate is used for heating, while the degree of heating is ignored. When the degree of drying is insufficient, the moisture content in the particles is too high, which may cause the product to be susceptible to moisture and deterioration, and even affect the performance and shelf life of the product. On the contrary, if it is over-dried, it may cause the particles to be over-hardened, brittle, or even cracked, which also affects the quality and stability of the product. In addition, uncontrollable degree of drying often means waste of energy (such as heat energy and electrical energy). Insufficient drying requires increased drying time and energy input, while over-drying is purely meaningless energy consumption.

[0006] 3. The document relies solely on the heating plate for heating, but fails to adequately monitor and control the degree of heating. This single, unregulated heating method poses significant risks, especially for temperature-sensitive materials such as plastic pellets. Excessive temperatures will not only cause them to melt, but also lead to a series of adverse consequences; plastic pellets will gradually lose their original shape, become soft and eventually melt in a high temperature environment. Once melting occurs, the molten plastic may adhere to the inner wall of the material hopper. Over time, this adhesion phenomenon will become more serious and eventually lead to blockage of the material hopper. This will not only affect the smooth progress of the drying process, but may also cause damage to the equipment, increase maintenance costs and downtime.

[0007] Therefore, an extruder that can assist in keeping the raw materials dry is proposed to solve the above problems. Summary of the invention

[0008] In view of this, the technical problem to be solved by the present invention is to propose an extruder that can assist in keeping the raw materials dry, so as to solve the problems of energy waste and uncontrollable material drying caused by material drying in the prior art.

[0009] To achieve the above object, the present invention provides the following technical solution: an extruder that can assist in keeping raw materials dry, comprising an operating table, a hot extrusion device is installed on one side of the upper surface of the operating table, a feed chamber is installed on the side of the operating table close to the hot extrusion device, a drying bin is connected above the feed chamber, a material hopper is fixedly connected to the upper surface of the drying bin, and also includes a circulatory drying mechanism and a drying adjustment mechanism, the circulatory drying mechanism is arranged in the middle of the drying bin, and the drying adjustment mechanism is arranged on the upper surface of the drying bin;

[0010] The recyclable drying mechanism is used for sustainable drying of particles;

[0011] The drying adjustment mechanism is used for adjusting the drying of particles.

[0012] Preferably, the circulatory drying mechanism includes an arc-shaped spiral guide plate, which is fixedly connected to the inner wall of the drying bin, a drying hole is opened at the bottom of the arc-shaped spiral guide plate, a moisture guide pipe is fixedly connected to the bottom of the drying hole, the outer surface of the moisture guide pipe is fixedly connected to the drying bin, and the end of the moisture guide pipe away from the drying hole is fixedly connected to a heat recovery evaporation chamber, and both ends of the heat recovery evaporation chamber are mounted on the hot extrusion device.

[0013] Preferably, a spiral diverter plate is fixedly connected to the inner wall of the heat recovery evaporation chamber, a dry gas guide pipe is fixedly connected to the bottom of one end of the heat recovery evaporation chamber away from the moisture guide pipe, the outer surface of the dry gas guide pipe is fixedly connected to the operating table, and the end of the dry gas guide pipe away from the heat recovery evaporation chamber is fixedly connected to a secondary drying chamber.

[0014] Preferably, the secondary drying chamber is sleeved on the outer surface of the drying bin, the drying gas flow guide pipe is fixedly connected to a heat conduction pipe on the side close to the secondary drying chamber, the outer surface of the heat conduction pipe is fixedly connected to the middle of the upper surface of the drying bin, and the secondary drying chamber is fixedly connected to an exhaust pipe on the side away from the heat conduction pipe.

[0015] Preferably, the drying adjustment mechanism comprises a baffle, one end of which is rotatably connected to the bottom of the material hopper, and a push rod is symmetrically rotatably connected to the middle of the baffle.

[0016] Preferably, one end of the push rod away from the spoiler is rotatably connected to a threaded slider, and the bottoms of both ends of the threaded slider are slidably connected to intake fixed chambers.

[0017] Preferably, the fixed air intake chamber is fixedly connected to the upper end of the arc-shaped spiral guide plate, the outer surface of the fixed air intake chamber is fixedly connected to the inner wall of the drying bin, and a threaded rod is threadedly connected to the middle portion of the threaded slider.

[0018] Preferably, a micro servo motor is provided at one end of the threaded rod away from the spoiler, the micro servo motor is mounted on the air intake fixed chamber, and one end of the threaded rod is fixedly connected to the drive shaft of the micro servo motor.

[0019] Compared with the prior art, the extruder provided by the present invention can assist in keeping the raw materials dry, and has the following beneficial effects:

[0020] 1. Through the setting of the arc spiral guide plate and the drying hole, when the material slides along the surface of the arc spiral guide plate to the feed chamber under the guidance of the arc spiral guide plate, the output wind flows into the wet gas guide pipe along the drying hole through the blower, and flows to the heat recovery evaporation chamber through the wet gas guide pipe. At this time, the heat generated by the hot extrusion inside the hot extrusion device will heat the airflow in the heat recovery evaporation chamber, and the heated airflow will be transported to the secondary drying chamber along the dry gas guide pipe. The metal heat exchange on the surface of the drying bin generates a certain temperature inside the drying bin. At this time, the arc spiral guide plate also begins to gradually generate heat under the action of heat transfer, and the flow The particles moving on the surface of the arc-shaped spiral guide plate will be gradually heated and dried. Compared with the setting of a blower and a heating plate for drying in the comparative document, which causes energy waste, the heat of the blower can be heated by the heat generated by the extruder itself, and the surface of the arc-shaped spiral guide plate is dried and heated again by the heated wind. Through the setting of the present invention, not only the wind power inside the blower can be recycled, but the water vapor after drying can be recycled to the heat recovery evaporation chamber to be dried again, and the dried gas can be recycled for drying materials, which can not only reduce the electricity consumption caused by the additional use of the heating body, but also save energy consumption and enhance the sustainable use of the equipment.

[0021] 2. The flow rate of the material in the material hopper in the arc-shaped spiral guide plate can be controlled by setting the baffle plate. Under the heat exchange drying effect of the arc-shaped spiral guide plate and the inner wall of the drying bin, by adjusting the opening and closing angle of the baffle plate, not only the falling speed of the material can be controlled to prevent material congestion, but also the flow rate of the material in the arc-shaped spiral guide plate can be controlled by adjusting the angle of the baffle plate. When the material passes through the arc-shaped spiral guide plate under the flow speed control, the drying time of the material on the surface of the arc-shaped spiral guide plate can be controlled, thereby further realizing the control of the dryness of the material and reducing the melting and sticking phenomenon of the material caused by excessive drying.

[0022] Compared with the traditional drying method, another highlight of the present invention is that it uses a spiral arc spiral guide plate structure as the guide flow path for the material. This design not only makes full use of the material's own gravity, making the drying process more efficient and energy-saving, but also ensures that the material can evenly receive the heat generated by the heat exchange between the arc spiral guide plate and the inner wall of the drying bin during the flow process, thereby achieving uniform drying of the material surface. This improvement significantly reduces the uneven drying phenomenon caused by material accumulation, and improves the drying effect and product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] For further examples, please refer to Figures 1 to 7 As shown:

[0047] The drying adjustment mechanism 3 includes a baffle plate 31, one end of which is rotatably connected to the bottom of the material hopper 14, and a push rod 32 is symmetrically rotatably connected to the middle of the baffle plate 31;

[0050] A micro servo motor 36 is disposed at one end of the threaded rod 35 away from the spoiler 31. The micro servo motor 36 is mounted on the air intake fixed chamber 34. One end of the threaded rod 35 is fixedly connected to the drive shaft of the micro servo motor 36.

[0051] Wherein: the micro motor is electrically connected to the control system.

[0052] Compared with the reference document, through the implementation of this embodiment, another highlight of the present invention is that the spiral arc spiral guide plate 21 structure is used as the guide flow path of the material. This design not only makes full use of the material's own gravity, making the drying process more efficient and energy-saving, but also ensures that the material can evenly receive the heat generated by the heat exchange between the arc spiral guide plate 21 and the inner wall of the drying bin 13 during the flow process, thereby achieving uniform drying of the material surface. This improvement significantly reduces the uneven drying phenomenon caused by material accumulation, and improves the drying effect and product quality.

[0053] Everything in the above example works like this:

[0054] In the initial state: the operator places the particles to be extruded into the material hopper 14 , and at this time, the baffle 31 is closed to the bottom of the material hopper 14 .

[0055] The following is the working process of the recyclable drying mechanism 2 for sustainable drying of particles:

[0056] At this time, after the feed chamber 12 is running and the baffle plate 31 at the bottom of the material hopper 14 is open, the blower connected to the air intake fixed chamber 34 is started. At this time, when the blower is started, because the air intake fixed chamber 34 is connected to the upper end of the drying hole 22, the gas blown by the blower will flow along the drying hole 22 to the moisture guide pipe 23 at the bottom of the drying hole 22. At this time, the gas is transmitted to the heat recovery evaporation chamber 24 through the moisture guide pipe 23. Since the heat recovery evaporation chamber 24 needs to be preheated when it is started, the material can be softened and its viscosity can be reduced by preheating, making it easier to The hot extruder 11 is extruded, which can not only reduce the resistance and energy consumption in the extrusion process, but also improve the quality and output of the extruded product; at this time, a large amount of heat will be generated on the surface of the hot extrusion device 11, and the heat of the surface of the hot extrusion device 11 will be exchanged by the gas in the heat recovery evaporation chamber 24. At this time, the exchanged gas begins to flow along the bottom of the end of the heat recovery evaporation chamber 24 away from the moisture guide pipe 23 to the dry gas guide pipe 26. At this time, under the continuous gas delivery of the blower, the heated gas will be transmitted along the dry gas guide pipe 26 to the secondary drying chamber 27, and because the secondary drying chamber 27 is wrapped in the drying bin 1 3 outer surface, at this time, the heat transfer through the secondary drying chamber 27 and the surface of the drying chamber 13 will gradually generate hot air flow inside the drying chamber 13, and because the drying chamber 13 and the surface of the arc-shaped spiral guide plate 21 are made of metal, when the secondary drying chamber 27 is continuously heat-transferred, the heat conduction function of the metal will generate heat in the inner wall of the drying chamber 13, the surface of the arc-shaped spiral guide plate 21 and the drying hole 22, and when the operator controls the drying chamber 13 to open at the bottom of the material hopper 14 through the intelligent control interface, the gas after the heat exchange on the particle surface by the blower will flow into the heat recovery evaporation chamber 24 again for re-evaporation. The secondary heated gas flows to the secondary drying chamber 27 for circulating drying. Through the arrangement of the present invention, the heat of the blower can be heated by the heat generated by the extruder itself, and the surface of the arc-shaped spiral guide plate 21 is dried and heated again by the heated wind. Through the arrangement of the present invention, not only the wind power inside the blower can be recycled, but the water vapor after drying can be recycled to the heat recovery evaporation chamber 24 to be dried again, and the dried gas can be recycled for drying materials, which can not only reduce the electricity consumption caused by the additional use of the heating body, but also save energy consumption and enhance the sustainable use of the equipment.

[0057] In traditional methods, wind power is often directly discharged after completing its task. However, the present invention allows wind power to circulate continuously in the system through innovative loop design, reducing energy waste. The water vapor heated and dried by the arc-shaped spiral guide plate 21 is not directly discarded, but is cleverly guided to the heat recovery evaporation chamber 24 for further drying. This step not only further removes residual moisture in the water vapor, but also allows heat energy that might have been lost to be recovered and reused. This dual utilization of heat energy not only improves the overall energy efficiency, but also significantly reduces the energy consumption cost in the production process.

[0058] Furthermore, the dried gas is recycled as a drying source for the material. This measure not only simplifies the production process, but also reduces the demand for external drying equipment. Compared with the traditional single additional drying equipment, the integrated design of the present invention greatly saves equipment investment and reduces maintenance costs; at the same time, since the drying process is completed in a closed system, the influence of external factors on the drying effect is reduced, thereby improving the drying quality and stability of the product.

[0059] Please refer to the above working process Figures 1 to 7 .

[0060] The following is the working process of the drying adjustment mechanism 3 for adjusting the drying of particles:

[0061] At this time, when the operator starts the micro servo motor 36 under the control of the control system, the micro servo motor 36 driving shaft is fixed to the threaded rod 35, so the micro servo motor 36 will drive the threaded rod 35 to rotate synchronously. Since the threaded rod 35 is threadedly connected to the threaded slider 33, and the bottom of the threaded slider 33 is slidably connected to the air intake fixed chamber 34, the threaded slider 33 is driven to slide on the surface of the air intake fixed chamber 34 by the rotation of the threaded rod 35. The push rod 32 is rotatably connected to the baffle plate 31 at the side away from the threaded slider 33. Since the baffle plate 31 is rotatably connected to the bottom of the material hopper 14, the rotation of the threaded rod 35 will drive the opening and closing adjustment of the baffle plate 31 at the bottom of the material hopper 14. By setting the baffle plate 31, the falling flow rate of the material in the material hopper 14 can be controlled by adjusting the inclination angle of the baffle plate 31. When the inclination angle of the baffle plate 31 is large, the material will pass through the baffle plate faster under the action of gravity, thereby accelerating the flow into the arc-shaped spiral guide plate 21. path; on the contrary, if the inclination angle of the baffle 31 is reduced, the falling speed of the material will be slowed down, thereby slowing down the flow speed of the material on the arc-shaped spiral guide plate 21; and then the flow speed of the material in the material hopper 14 in the arc-shaped spiral guide plate 21 can be controlled, and under the heat exchange drying effect between the arc-shaped spiral guide plate 21 and the inner wall of the drying bin 13, by adjusting the opening and closing angle of the baffle 31, not only the falling speed of the material can be controlled to prevent material congestion, but also the flow speed of the material in the arc-shaped spiral guide plate 21 can be controlled by adjusting the angle of the baffle 31. When the material is on the arc-shaped spiral guide plate 21, the drying time of the material on the surface of the arc-shaped spiral guide plate 21 can be controlled by controlling the flow speed, and the dryness of the material can be further controlled, which not only reduces the excessive moisture content in the particles when the drying degree is insufficient, which may cause the product to be susceptible to moisture and deteriorate, and even affect the product's performance and shelf life; at the same time, it can also reduce the excessive hardening, fragility, and even cracking of the particles caused by excessive drying, and can reduce its energy consumption and improve the efficiency of equipment use.

[0062] Compared with the traditional drying method, another highlight of the present invention is that it adopts a spiral arc spiral guide plate 21 structure as the guide flow path of the material. This design not only makes full use of the material's own gravity, making the drying process more efficient and energy-saving, but also ensures that the material can evenly receive the heat generated by the heat exchange between the arc spiral guide plate 21 and the inner wall of the drying bin 13 during the flow process, thereby achieving uniform drying of the material surface. This improvement significantly reduces the uneven drying phenomenon caused by material accumulation, and improves the drying effect and product quality.
