Description

Technical Field

[0001] This utility model relates to the field of fiber processing technology, specifically to a drying device for processing modified biomass fibers. Background Technology

[0002] In the field of modern materials processing, modified biomass fibers are widely used in textile, medical, and construction industries due to their renewable, environmentally friendly, and unique physicochemical properties. Drying, as a key process in the processing of modified biomass fibers, directly affects the quality of the fibers and their subsequent processing performance. Traditional drying methods often employ single hot air drying equipment, where hot air is directly delivered to the fibers from above to evaporate moisture. Since the fibers only receive hot air from above, the contact time with the hot air is limited and short, resulting in slow evaporation and low drying efficiency. To ensure thorough drying, the hot air drying time needs to be extended, increasing production costs. Furthermore, due to the weak penetrating power of hot air, the upper layer of the fiber can make good contact with the hot air and achieve drying, but the moisture in the lower layer is difficult to evaporate effectively, leading to significant differences in the degree of drying between the upper and lower layers of the fiber, resulting in uneven drying. Therefore, a drying device for modified biomass fiber processing is needed to solve the problems existing in the current technology. Utility Model Content

[0003] The purpose of this invention is to provide a drying device for processing modified biomass fibers, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a drying device for processing modified biomass fibers, comprising a belt conveyor and a hot air blower for drying, wherein the hot air blower is disposed above the belt conveyor, and a lower drying mechanism is disposed on the upper part of the belt conveyor, the lower drying mechanism comprising a hollow side baffle, a heat-conducting barrier shell and a lower air outlet, the hollow side baffle being fixed on the base of the belt conveyor, the heat-conducting barrier shell being fixed between the inner walls of the two hollow side baffles, the heat-conducting barrier shell being hollow inside, and a lower air outlet communicating with the hollow cavity being opened on one side surface of the heat-conducting barrier shell.

[0005] Preferably, a first pair of interfaces is provided on one side surface of the hollow side baffle, and the first pair of interfaces is connected to the inner cavity of the hollow side baffle.

[0006] Preferably, a second pair of interfaces is provided on one side surface of the thermal barrier shell, and the second pair of interfaces is connected to the lower air outlet.

[0007] Preferably, the hot air blower includes a heating box and a fan, an air collecting hood is fixed to the upper end of the hollow side baffle, a heating box is fixed to the upper end of the air collecting hood, and a fan is fixed to the center of the top of the heating box.

[0008] Preferably, a hot air duct is fixed between the heating box and the lower drying mechanism, and the two ends of the hot air duct are provided with connecting ports.

[0009] Preferably, one side of the heat-conducting barrier shell is provided with a sloping surface, the inner area of ​​the belt conveyor is provided with a conveyor belt that rotates in a circular manner, and the bottom of the heat-conducting barrier shell is attached to the upper surface of the conveyor belt.

[0010] This invention provides a drying device for processing modified biomass fibers, which has the following advantages compared with the prior art: Through the lower drying mechanism, the modified bio-fiber material is continuously driven by the conveyor belt to cross the heat-conducting barrier shell through which hot air is introduced. When the fiber climbs up the heat-conducting barrier shell along the slope and comes into contact with the heated bottom of the heat-conducting barrier shell, the lower layer of the fiber is initially dried. Compared with the traditional single hot air drying method, this increases the contact opportunity and duration between the fiber and the hot air, accelerates the moisture evaporation rate, effectively improves the drying efficiency, and shortens the processing time. By using a conveyor belt, a heat-conducting barrier shell, and a lower air outlet, the forward momentum of the conveyor belt and the pushing force of the subsequent fibers are used to achieve automatic movement and fall of the fibers on the heat-conducting barrier shell. During the fall of the fibers, the lower air outlet blows hot air from the bottom, which makes up for the problem of insufficient drying in the lower layer caused by the weak penetration of hot air. This significantly improves the uneven drying of the upper and lower layers of fibers and ensures that the overall drying effect of the fibers is consistent. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 This utility model provides a drying device for processing modified biomass fibers, including a belt conveyor 1 and a hot air blower for drying. The belt conveyor 1 provides a continuous conveying platform for modified biomass fiber material. The fiber material is conveyed from the feeding end to the drying area through the internally circulating conveyor belt 14. The hot air blower is set above the belt conveyor 1. A lower drying mechanism 5 is set on the upper part of the belt conveyor 1. The lower drying mechanism 5 includes a hollow side baffle 6, a heat-conducting barrier shell 7 and a lower air outlet 10. The hollow side baffle 6 is fixed on the base of the belt conveyor 1. The heat-conducting barrier shell 7 is fixed between the inner walls of the two hollow side baffles 6. The interior of the heat-conducting barrier shell 7 is hollow. A lower air outlet 10 communicating with the hollow cavity is opened on one side surface of the heat-conducting barrier shell 7.

[0015] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that a first pair of interfaces 11 are provided on one side surface of the hollow side baffle 6, which are connected to the inner cavity of the hollow side baffle 6. A second pair of interfaces 12 are provided on one side surface of the heat-conducting barrier shell 7, which are connected to the lower air outlet 10. The fiber material climbs up the heat-conducting barrier shell 7 along the slope 13 driven by the conveyor belt 14. The subsequent pushing of the fiber material causes it to fall back automatically, realizing the "climbing-falling" movement of the fiber material, increasing the contact area and time with the heat-conducting surface, and improving the bottom drying effect. The surface of the heat-conducting barrier shell 7 is heated by the internal hot air flow and directly contacts the bottom of the fiber material. The drying is assisted by heat conduction, which solves the problem of insufficient drying of the lower layer caused by the weak penetration of traditional hot air. When the fiber material falls back from the heat-conducting barrier shell 7, the lower air outlet 10 blows hot air to the bottom of the fiber material, which further heats the lower layer of the fiber material through forced convection, making up for the limitation of hot air penetration from top to bottom and improving the drying uniformity.

[0016] Further as Figure 1 , Figure 2 and Figure 4As shown, it is worth noting that the hot air blower includes a heating box 3 and a fan 4. An air collecting hood 2 is fixed to the upper end of the hollow side baffle 6. The heating box 3 is fixed to the upper end of the air collecting hood 2. The fan 4 is fixed to the center of the top of the heating box 3. A hot air duct 8 is fixed between the heating box 3 and the lower drying mechanism 5. Connecting ports 9 are provided at both ends of the hot air duct 8.

[0017] Further as Figure 1 As shown, it is worth noting that a slope 13 is provided on one side of the thermal barrier shell 7, and a conveyor belt 14 is provided in the internal area of ​​the belt conveyor 1 for circulating rotation. The conveyor belt 14 directly carries the modified bio-fiber material. The continuous feeding of the fiber material is achieved through the circulating rotation, so that it passes through the drying area in sequence. The bottom of the thermal barrier shell 7 is attached to the upper surface of the conveyor belt 14.

[0018] The solution has the following working process: Before use, the heating wire in the heating box 3 is working, and the blower 4 can generate hot air. Since the conveyor belt 14 on the belt conveyor 1 can drive the modified bio-fiber material laid on it to feed into the hot air drying chamber, the hot air dries the modified bio-fiber material. During use, hot air is introduced into the hollow side baffle 6 and the heat-conducting barrier shell 7 through the hot air duct 8. During the transfer of the modified bio-fiber material by the conveyor belt 14, the modified bio-fiber material climbs up the heat-conducting barrier shell 7 along the slope 13 under the forward action of the conveyor belt 14. The modified bio-fiber material on the heat-conducting barrier shell 7 is automatically pushed back onto the conveyor belt 14 by the subsequent modified bio-fiber material. In this way, the modified bio-fiber material can continuously cross the heat-conducting barrier shell 7 through which hot air is introduced during the drying process. The heat-conducting barrier shell 7, which heats up the surface of the modified bio-fiber material in contact with it, can dry its bottom, thereby improving the situation where the lower layer of the modified bio-fiber material has poor local drying effect due to its distance from the hot air outlet and the weak penetration of the hot air. During the process of the modified bio-fiber material being pushed onto the heat-conducting barrier shell 7 and falling onto the conveyor belt 14, the lower air outlet 10 of the heat-conducting barrier shell 7 can blow hot air from its bottom during the falling process of the modified bio-fiber material, thereby further improving the uniform drying effect of the lower layer of the modified bio-fiber material.
