Description

Technical Field

[0001] This application relates to the field of belt conveyor equipment technology, specifically a conveyor belt device for belt dryers. Background Technology

[0002] Belt dryers are continuous drying equipment used in batch production. They are suitable for drying sheet-like, strip-like, and granular materials with good air permeability and are widely used in many industries such as metallurgy, building materials, ceramics, fertilizers, chemicals, food, and vegetables. For example, in the food industry, they are used to dry dried fruits and vegetables; in the chemical industry, they are used to dry various chemical raw material granules. The conveyor belt is a key component of the belt dryer, and its main function is to carry and transport materials within the dryer. It is usually made of metallic materials, such as stainless steel or nickel alloys, and has a certain strength and high-temperature resistance, enabling it to withstand the weight of the materials and operate within the dryer for extended periods.

[0003] For example, the patent with announcement number CN217807581U discloses a belt dryer conveying device with an anti-clogging mechanism, including a frame, a mesh belt conveyor, a drying box, an anti-clogging component and a cleaning roller. By setting the cleaning roller, a second rotary motor drives the cleaning roller to rotate, cleaning the material residue remaining in the wire mesh of the mesh belt conveyor, preventing the material residue from clogging the mesh surface after a long time and affecting the subsequent drying effect.

[0004] The aforementioned patented cleaning roller adopts a single-sided contact cleaning design. In actual operation, it can only clean one side of the wire mesh of the mesh belt conveyor, resulting in material debris, oil stains, dust and other impurities remaining on the other side of the wire mesh. As the usage time increases, the residual impurities will gradually accumulate, which will affect the quality of the product.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0038] like Figure 1-6 As shown, this application provides a conveyor belt device for a belt dryer, including a conveyor assembly 2, which is the basic part of the entire device. The conveyor assembly 2 includes a conveyor body 21, which adopts a high-strength steel structure design, possessing good rigidity and stability, and capable of withstanding long-term, high-intensity operation. A conveyor belt body 22 is installed on the conveyor body 21. This belt body is made using a special weaving process, possessing high temperature resistance, corrosion resistance, and wear resistance, and can adapt to the high-temperature environment during the drying process and the frictional loss during material conveying.

[0039] The conveyor belt body 22 is driven by a drive mechanism (not shown in the figure) on the conveyor body 21. The drive mechanism adopts a mature combination of variable frequency speed control motor and transmission chain. The motor can accurately adjust the running speed of the conveyor belt body 22 according to actual production needs, achieving stepless speed change from 0.5-5m / min. Through variable frequency speed control technology, the drying time requirements of different materials can be met. Since the drive mechanism of the conveyor body 21 uses existing mature technology, it will not be described in detail here.

[0040] A drying assembly 1 is fixed at the upper end of the conveyor body 21. The drying assembly 1 includes a drying box 11 fixedly installed at the upper end of the conveyor body 21. The drying box 11 adopts a trapezoidal frame structure design, which can optimize the internal airflow distribution and improve drying efficiency. Fans 12 are fixedly installed on both sides and the top of the drying box 11, which are responsible for quickly transporting a large amount of air to form an airflow and ensure that the airflow can evenly cover the entire internal space of the drying box 11.

[0041] The drying chamber 11 is equipped with multiple heating tubes 13 that are evenly distributed inside. The heating tubes 13 are made of high-temperature resistant stainless steel and filled with high-efficiency electric heating wires. They are also equipped with an intelligent temperature control system (not shown in the figure). In actual operation, the fan 12 blows air toward the heating tubes 13. The heated air forms circulating hot air in the drying chamber 11, which performs all-round and uniform drying on the items conveyed on the conveyor belt body 22.

[0042] A cleaning component 3 is fixed in the middle of the conveyor body 21. The cleaning component 3 includes a mounting plate 31 that is fixed to the lower end of the conveyor body 21 by bolts. The mounting plate 31 is made of high-strength aluminum alloy, which is lightweight and high-strength. It can reduce the weight of the entire device while ensuring structural stability. At one end of the mounting plate 31, a mounting bracket 32 ​​is fixed by bolts. The mounting bracket 32 ​​adopts a hollow frame structure design to provide sufficient installation space for the internal transmission components. At the other end of the mounting plate 31, a limit plate 33 is fixed by bolts.

[0043] Between the mounting frame 32 and the limiting plate 33, a first cleaning brush 34 and a second cleaning brush 35 are arranged vertically. The first cleaning brush 34 uses high-density nylon bristles with moderate bristle hardness, which can effectively remove material residues adhering to the outer wall of the conveyor belt body 22. The second cleaning brush 35 also uses high-density nylon bristles and can clean material residues adhering to the inner wall of the conveyor belt body.

[0044] The first cleaning brush 34 and the second cleaning brush 35 are driven by a drive unit mounted on the mounting bracket 32. The drive unit consists of a drive motor 36, a transmission gear set, and a transmission shaft 37. The transmission shaft 37 and the driven shaft 38 are rotatably mounted at both ends of the mounting bracket 32, respectively. The transmission gear set consists of a first gear 39 and a second gear 310 fixedly mounted on the transmission shaft 37 and the driven shaft 38, respectively. The first gear 39 and the second gear 310 adopt a high-precision involute tooth profile design, and through precise meshing, they can realize the relative rotation of the transmission shaft 37 and the driven shaft 38. At the lower end of one side of the mounting bracket 32, a dedicated drive motor 36 is fixedly mounted. This drive motor 36 adopts a high-torque, low-noise design, and its output end is fixedly mounted to the transmission shaft 37 through a high-strength coupling, which can stably transmit power to the transmission shaft 37.

[0045] To facilitate the installation, disassembly, and replacement of the cleaning brushes and improve the maintenance efficiency of the equipment, the first cleaning brush 34 and the second cleaning brush 35 are fixedly installed between the mounting bracket 32 ​​and the limiting plate 33 using a quick-release mechanism. The quick-release mechanism includes a first coupling 311 disposed between the drive shaft 37 and the first cleaning brush 34, and a second coupling 312 disposed between the driven shaft 38 and the second cleaning brush 35. One end of the drive shaft 37 and the driven shaft 38 is provided with a locking block (not shown in the figure). The locking block adopts a trapezoidal cross-section design, which has good guiding and stability. One end of the first cleaning brush 34 and the second cleaning brush 35 is provided with a matching locking groove (not shown in the figure). During installation, simply align the locking groove of the first cleaning brush 34 with the locking block of the drive shaft 37 and gently push it in to achieve locking. Then, it is fixedly connected through the first coupling 311. Similarly, the second cleaning brush 35 can be locked onto the driven shaft 38 and fixedly connected through the second coupling 312. This makes the replacement of the cleaning brushes simple and quick, without the need for complicated tools, greatly shortening the maintenance time of the equipment.

[0046] In addition, the outer walls of the other ends of the first cleaning brush 34 and the second cleaning brush 35 are respectively fixed with a first rolling bearing 313 and a second rolling bearing 314. The first rolling bearing 313 and the second rolling bearing 314 are high-precision deep groove ball bearings, which can effectively reduce the friction during brush rotation and improve rotation efficiency. The outer walls of the first rolling bearing 313 and the second rolling bearing 314 are respectively snapped into two U-shaped grooves (not shown in the figure) on the limiting plate 33. The inner walls of the U-shaped grooves are finely machined and have a smooth surface, which can fit tightly with the rolling bearings. The quick-release mechanism also includes a first limiting block 315 and a second limiting block 316 respectively snapped into the two U-shaped grooves on the limiting plate 33. The first limiting block 315 is snapped into the outer wall of the second rolling bearing 314, and the second limiting block 316 is snapped into the outer wall of the first rolling bearing 313. The first limiting block 315 and the second limiting block 316 are fixed to the limiting plate 33 with high-strength bolts, which can securely fix and install the first cleaning brush 34 and the second cleaning brush 35, and can also effectively prevent the brushes from loosening and shifting during equipment operation, ensuring the stability of the cleaning effect.

[0047] Meanwhile, a baffle 4 is fixedly installed on the conveyor body 21 by bolts. The baffle 4 is made of transparent acrylic material, which not only has good visibility, making it convenient for operators to observe the internal cleaning status, but also effectively prevents the debris swept by the first cleaning brush 34 and the second cleaning brush 35 from falling onto the items being dried above the conveyor belt body 22, thus ensuring the cleanliness of the dried materials and the quality of the products.

[0048] Working principle: When using, first confirm that the conveyor belt body 22 is undamaged and free of material residue, that the cleaning brush is securely installed, and that the limit block of the quick-release mechanism is tightly engaged with the rolling bearing to prevent loosening during operation. Check whether the heating tube 13, fan 12 and temperature control system inside the drying chamber 11 are normal, and that the baffle 4 is free of cracks to ensure transparency and visibility.

[0049] Based on the material characteristics, the speed of the conveyor belt is set by the variable frequency speed control motor to determine the residence time of the material in the drying chamber 11. The target temperature of the heating tube 13 is set in the intelligent temperature control system to match the material drying process requirements. The material to be dried is evenly spread on the conveyor belt body 22 to avoid local accumulation that affects the drying uniformity. The conveyor belt is supported by the high-strength steel structure of the conveyor body 21 to ensure load-bearing stability.

[0050] When the variable frequency speed control motor is turned on, the motor drives the conveyor belt body 22 to rotate through the transmission chain. The conveyor belt moves from the feed end to the discharge end of the drying chamber 11 at a set speed, and the material enters the drying chamber 11 accordingly. After the heating tube 13 is powered on, the internal electric heating wire heats up. The stainless steel shell is protected against high temperature. The intelligent temperature control system monitors the temperature in real time and automatically adjusts the heating power to maintain the set temperature.

[0051] The fans 12 on both sides and top of the drying chamber 11 are started, blowing air towards the heating tube 13. The heated air forms hot air, which is evenly covered by the material above the mesh belt through the optimized airflow distribution of the trapezoidal frame structure of the drying chamber 11. The hot air is in full contact with the material, and the moisture is removed through convection heat exchange. A circulating hot air path is formed inside the drying chamber 11 to ensure that the material is dried in all directions. As the material moves with the mesh belt, the hot air continues to act until the moisture content reaches the discharge end of the drying chamber 11.

[0052] While the material is drying, the drive motor 36 of the cleaning component 3 starts and transmits power to the transmission shaft 37 through the coupling. The first gear 39 on the transmission shaft 37 meshes with the second gear 310 on the driven shaft 38, driving the first and second cleaning brushes 35 to rotate synchronously in opposite directions. The high-density nylon bristles of the first cleaning brush 34 and the second cleaning brush 35 are in close contact with the surface of the mesh belt. When rotating, they scrape off the material residue adhering to the inner and outer walls of the mesh belt, preventing the residue from accumulating and affecting the operation of the mesh belt or contaminating the subsequent materials.

[0053] The brush is connected to the drive shaft 37 and the driven shaft 38 via a quick-release structure. When rotating, the first and second rolling bearings 314 roll in the U-shaped groove of the limiting plate 33 to reduce friction. The limiting block fixes the position of the brush to prevent it from shifting during cleaning and to ensure stable cleaning effect. The residue scraped off by the cleaning brush falls to the collection device (not shown in the figure) below the conveyor body 21, preventing the residue from falling back onto the material surface through the mesh belt gaps.

[0054] After drying, the material moves along the mesh belt to the discharge end of the conveyor body 21, where it is collected by the operator or enters the subsequent process. The transparent acrylic baffle 4 blocks the splashing of residue throughout the process, ensuring the cleanliness of the material.

[0055] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
