Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of honeysuckle industrial production equipment, specifically to a belt dryer for honeysuckle. Background Technology
[0002] With the expansion of honeysuckle planting area and the increase in yield, drying and storage have become bottlenecks hindering the development of the honeysuckle industry. In the industrial processing of honeysuckle, the honeysuckle drying production line consists of equipment such as a blanching coolant, automated dryer, conveyor, and steam heat source. The production line is highly mechanized, forming a streamlined process from feeding, blanching and cooling, automatic drying to discharge, greatly reducing the labor intensity of workers and improving product quality. Drying the honeysuckle is a crucial step. Traditional belt dryers have many shortcomings. On the one hand, the material transmission process lacks effective buffering and dispersion; honeysuckle is easily broken due to collision and compression during conveying and transition, seriously affecting the product's appearance and quality. On the other hand, the hot air system design is simplistic, unable to achieve precise layered drying, resulting in uneven drying and significant loss of effective components, further exacerbating the decline in honeysuckle quality. This makes it difficult to meet the high-quality and high-efficiency requirements of modern honeysuckle drying processing, necessitating optimization and improvement of existing equipment. Utility Model Content
[0003] To address the aforementioned shortcomings, this invention aims to provide a belt dryer for honeysuckle. This invention, taking into account the characteristics of honeysuckle, utilizes a three-layer staggered mesh belt with varying apertures, combined with a buffer transition mechanism and a heating device, to effectively reduce the breakage rate of honeysuckle during the drying process, achieving precise layered drying of honeysuckle and improving drying efficiency and product quality.
[0004] To achieve the above technical objectives, the following technical solutions were adopted:
[0005] A belt dryer for honeysuckle includes a housing, a conveying mechanism, a buffer transition structure, and a heating device. The housing houses the conveying mechanism and the buffer transition structure, and has openings corresponding to the heating device on its top, sides, and bottom. The conveying mechanism includes three horizontally arranged staggered mesh belts, with the mesh belt aperture decreasing progressively from top to bottom, and each layer running in opposite directions. The middle layer of mesh belt has wavy guide strips on its surface. The buffer transition structure includes an inclined buffer plate and an elastic buffer pad. One end of the buffer plate is connected to the discharge end of the upper mesh belt, and the other end extends above the feed end of the lower mesh belt. The elastic buffer pad is laid on the surface of the buffer plate. The heating device includes an electric heater at the top of the housing, a steam heat exchanger on the side of the housing, and an air source heat pump at the bottom of the housing.
[0006] Furthermore, the mesh belt includes a top mesh belt, a middle mesh belt, and a bottom mesh belt. The top mesh belt is connected to the material inlet, and the bottom mesh belt is connected to the material outlet.
[0007] Furthermore, the top layer mesh belt has an aperture of 8mm, the middle layer mesh belt has an aperture of 6mm, and the bottom layer mesh belt has an aperture of 4mm.
[0008] Furthermore, the wavy guide strips on the middle mesh belt are set at a 15° angle to the running direction of the middle mesh belt to induce lateral diffusion of materials.
[0009] Furthermore, the surface of the elastic buffer pad is provided with a plurality of hemispherical buffer grooves in an alternating pattern.
[0010] Furthermore, a baffle plate is provided opposite to the buffer plate, and the baffle plate is inclined in the opposite direction to the inclination of the buffer plate to prevent material from overflowing.
[0011] Furthermore, the mesh belt is provided with elastic baffles on both sides, which can both limit the lateral overflow of materials and buffer the impact force of materials.
[0012] Furthermore, the air outlet direction of the steam heat exchanger is opposite to the running direction of the middle mesh belt.
[0013] Furthermore, a dehumidifier is installed on the top of the cabinet.
[0014] Furthermore, each hot air outlet of the heating device is equipped with a cotton mesh filter layer to prevent high-temperature airflow from directly impacting the material.
[0015] The beneficial effects achieved by this utility model are as follows:
[0016] Compared with existing technologies, this utility model provides a belt dryer for honeysuckle. Through a three-layer staggered mesh belt design, combined with different apertures and corrugated guide strips, this utility model enables the material to tumble and spread evenly using its own gravity. Combined with the effective buffering of the buffer transition structure, it significantly reduces the breakage rate of honeysuckle during transmission, ensuring product quality. The layered layout and reasonable configuration of the heating device allow honeysuckle to receive targeted hot air treatment at different drying stages, achieving precise layered drying, improving drying efficiency and uniformity, and effectively reducing the loss of effective components. Furthermore, the elastic sidewalls and baffles ensure the stability of material transmission from multiple angles, preventing material spillage. The cotton mesh filter layer prevents high-temperature airflow from impacting the material, providing comprehensive protection for the honeysuckle and improving product quality.

Detailed Implementation
[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. The described embodiments are merely some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] like Figure 1 As shown, the present invention provides a belt dryer for honeysuckle, comprising a housing 1, a transmission mechanism, a buffer transition structure, and a heating device.
[0025] The housing 1 houses the transmission mechanism and the buffer transition structure, and has openings on its top, sides and bottom corresponding to the heating device.
[0026] like Figure 1-3As shown, the conveying mechanism includes three horizontally arranged staggered mesh belts 2, each running in opposite directions to form an "S"-shaped material conveying path. This allows the material to continuously change position and direction throughout the conveying process, undergoing multiple flips and movements to ensure contact with hot air and achieve uniform drying. The mesh belts 2 include a top mesh belt 21, a middle mesh belt 22, and a bottom mesh belt 23. The top mesh belt 21 is connected to the material inlet 10, and the bottom mesh belt 23 is connected to the material outlet 11. The aperture of the mesh belts 2 decreases progressively from top to bottom (8mm for the top layer, 6mm for the middle layer, and 4mm for the bottom layer) to ensure the material... The material will not fall during the transmission process, and its movement space can be reasonably restricted according to the characteristic of the material gradually shrinking during the drying process to ensure the drying effect. The surface of the middle mesh belt 22 is provided with wavy guide strips 221, which are set at a 15° angle with the running direction of the middle mesh belt 22. When the material dries to the middle mesh belt, the surface moisture decreases and it is easy to clump. The wavy guide strips 221 set at an angle are used to mechanically disperse the material and induce the material to diffuse laterally, while increasing the hot air residence time. The mesh belt 2 has elastic baffles on both sides, which can not only limit the lateral overflow of the material, but also buffer the impact of the material.
[0027] like Figure 4 As shown, the buffer transition structure includes an inclined buffer plate 3 and an elastic buffer pad 4. One end of the buffer plate 3 is connected to the discharge end of the upper mesh belt 2, and the other end extends above the feed end of the lower mesh belt 2. The elastic buffer pad 4 is laid on the surface of the buffer plate 3, and its surface is provided with multiple hemispherical buffer grooves 41, which can effectively disperse the impact force when the material falls and prevent the material from being damaged by collision. A baffle plate 9 is provided opposite to the buffer plate 3. The baffle plate 9 is inclined in the opposite direction to the inclination of the buffer plate 3 to prevent it from overflowing due to inertia or excessive sliding speed, and to ensure that the material can be accurately and smoothly transitioned to the lower mesh belt to avoid material overflow.
[0028] The heating device includes an electric heater 5 located at the top of the chamber, a steam heat exchanger 6 located on the side of the chamber, and an air source heat pump 7 located at the bottom of the chamber. The air outlet direction of the steam heat exchanger 6 is opposite to the running direction of the middle mesh belt 22, which prolongs the heat exchange time between the hot air and the material and enhances the heat exchange effect. At the same time, cotton mesh filter layers are set at each hot air outlet of the heating device to buffer and filter the high-temperature airflow, avoid the high-temperature airflow from directly impacting the material, and protect its quality. A dehumidifier 8 is installed at the top of the chamber 1 to remove the moisture released by the material during the drying process in a timely manner and maintain a dry drying environment inside the chamber 1.
[0029] Its working steps are as follows:
[0030] The honeysuckle to be dried is conveyed from the feed inlet 10 to the top mesh belt 21. The top mesh belt 21 has an 8mm aperture, which is sufficient to carry the honeysuckle and begin transport. The honeysuckle moves along the top mesh belt 21. Simultaneously, the electric heater 5 at the top of the chamber 1, the steam heat exchanger 6 on the side, and the air source heat pump 7 at the bottom are activated, sending hot air into the chamber 1 from the top, side, and bottom openings, respectively. The honeysuckle on the top mesh belt 21 moves along with the mesh belt, making full contact with the hot air and beginning the initial drying process. When the honeysuckle reaches the discharge end of the top mesh belt 21, it slides off the inclined buffer plate 3. The elastic buffer pad 4 and hemispherical buffer groove 41 on the surface of the buffer plate 3 cushion the honeysuckle, allowing it to smoothly transition to the middle mesh belt 22. At the same time, the baffle plate 9 on the opposite side prevents the honeysuckle from overflowing. The middle mesh belt 22 has a 6mm aperture and runs in the opposite direction. Its surface features wavy guide strips 221 that induce lateral diffusion of the honeysuckle, increasing the contact area between the honeysuckle and the hot air. Hot air from the steam heat exchanger 6 exchanges heat with the honeysuckle running in the opposite direction from the side, further drying the honeysuckle. When the honeysuckle reaches the discharge end on the middle mesh belt 22, it transitions again to the bottom mesh belt 23 via a buffer transition structure. The bottom mesh belt 23 has a 4mm aperture and runs in the opposite direction to the middle mesh belt 22, performing the final drying treatment on the honeysuckle. After drying, the honeysuckle is conveyed to the discharge port 11 for output, completing the entire drying process.
[0031] Throughout the process, the dehumidifier 8 at the top of the chamber 1 works continuously to remove moisture; the cotton mesh filter layer at the hot air inlet protects the honeysuckle from the impact of high-temperature airflow; the elastic baffles on both sides of the mesh belt 2 restrict the lateral overflow of materials and buffer the impact force, ensuring that the drying work is carried out efficiently and stably.
