Description

Technical Field

[0001] The utility model relates to the technical field of belt dryers, in particular to a belt dryer capable of preventing material from falling off. Background Art

[0002] Belt dryer is a continuous drying equipment widely used in industrial production. It is mainly used to dry small pieces of materials and fibrous materials, such as dehydrated vegetables, Chinese herbal medicine pieces and other materials with high moisture content and heat sensitivity. It can maintain the shape of the material during the drying process and can still maintain a certain shape after drying. In order to prevent the material from falling off the conveyor belt due to various reasons during the operation of the belt dryer, causing material waste, equipment damage or pollution, a belt dryer with anti-dropping is proposed.

[0003] According to the search, the Chinese patent document, announcement number: CN215447324U, discloses a belt dryer that prevents material from falling. By starting the No. 1 motor according to the amount of processed materials, the No. 1 motor rotates the counter-rotating threaded rod through the cooperation of the transmission wheel and the transmission belt. The rotation of the counter-rotating threaded rod can make the symmetrically arranged limit clamps move towards each other on the surface of the mesh conveyor belt, which can effectively limit the material during the transmission process and prevent the material from sliding off the side of the mesh conveyor belt. However, in actual use, since the mesh conveyor belt and the heating rod are set close to each other, when the material is in a high temperature area for a long time, it may cause damage to it or even cause the risk of fire and explosion; in addition, when the material is transferred between mesh conveyor belts at different heights, the device does not have good protection, so there is still a risk of causing material waste or damage to the equipment, which reduces the overall practicality. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a belt dryer for preventing material from falling, which has the advantages of multiple protections, improving drying efficiency and energy utilization, and reducing production costs, thereby solving the above technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a belt dryer for preventing material from falling, comprising a shell, a first material baffle plate is fixedly installed inside the shell, a roller and a second material baffle plate are installed inside the first material baffle plate, a mesh conveyor belt is installed on the outer side of the roller, a driving motor is fixedly installed on the front side of the shell, a first fan and a feeding table are fixedly installed on the top surface of the shell, a heating box is fixedly installed on the rear side of the shell, a first air inlet pipe is fixedly installed on the rear side of the heating box, a heater and a second fan are fixedly installed inside the heating box, a second air inlet pipe is fixedly installed on the outer side of the second fan, an air collecting hood is fixedly installed on the front side of the second fan, and an air outlet pipe is fixedly installed on the front side of the air collecting hood.

[0009] Through the above technical solution, when the three drive motors are started, the three drive motors can respectively drive the three rollers to rotate, and then drive the three mesh conveyor belts to move. Therefore, it can not only effectively drive the material to move and transport, but also increase the material movement path, thereby improving the drying efficiency; the other six first material baffles can also effectively prevent the material from falling or detaching from the two sides of the mesh conveyor belt, preventing material waste, equipment damage or pollution, etc., thereby improving the overall practicality of the device.

[0010] Preferably, there are two second baffle plates, one of which is installed on the inner side of the first baffle plate near the top of the shell near the left end, and the other second baffle plate is installed on the inner side of the first baffle plate near the middle of the shell near the right end.

[0011] Through the above technical solution, when the material falls from the top mesh conveyor belt, one of the second material baffles can prevent it from excessively moving or detaching from the left end of the mesh conveyor belt, ensuring that it can fall steadily on the mesh conveyor belt below. Similarly, the other second material baffle can also play the same role. At the same time, the second material baffle can also loosen and flip the material when it falls and transfers, thereby increasing the evaporation area of ​​the material and improving the drying efficiency.

[0012] Preferably, the first air intake pipe, the heater, the second fan and the second air intake pipe are all provided in plural numbers, and filters are fixedly installed inside the plural first air intake pipes.

[0013] Through the above technical solution, when multiple second fans and heaters are started, the second fans can suck external air into the interior of the heating box through the second air inlet pipe and the first air inlet pipe. The air is then heated by the heater and transported to the interior of the air outlet pipe and the shell, effectively improving the overall drying efficiency of the device. The filter can prevent impurities such as dust in the air from entering the interior of the heating box, thereby ensuring the operating environment inside the device.

[0014] Preferably, the air collecting hood and the air outlet pipe are both provided in plural numbers, and an air diffusion hood is installed at one end of the air outlet pipe away from the air collecting hood, and the air diffusion hood is arranged just below the mesh conveyor belt near the bottom of the shell.

[0015] Through the above technical solution, the heated air can pass through the wind collecting hood, the exhaust pipe and the inside of the air expansion hood in sequence after being transported by the second fan. Then, the heated air will be transmitted upward layer by layer, thereby effectively drying the material on the mesh conveyor belt. At the same time, the air expansion hood can ensure that the material can be sufficiently heated in each area, thereby improving the overall practicality of the device.

[0016] Preferably, the number of the first fans is plural.

[0017] Through the above technical solution, the heated air will gradually rise to the top of the shell after drying the material. At the same time, there will be a large amount of moisture in the air. At this time, the first fan can be started. The first fan can not only effectively discharge the water vapor to the outside of the device, but also correctly guide the air flow to avoid the water vapor from re-attaching to the surface of the material, thereby improving the overall practicality of the device.

Therefore, it can not only effectively drive the material to move and transport, but also increase the material movement path, thereby improving the drying efficiency; the other six first material baffles can also effectively prevent the material from falling or detaching from the two sides of the mesh conveyor belt, thereby preventing material waste, equipment damage or pollution, etc., and improving the overall practicality of the device; when the material falls from the top mesh conveyor belt, one of the second material baffles can prevent it from excessively moving or detaching from the left end of the mesh conveyor belt, ensuring that it can fall steadily on the mesh conveyor belt below. Similarly, the other second material baffle can also play the same role. At the same time, the second material baffle can also loosen and flip the material when it falls and transfers, thereby increasing the evaporation area of ​​the material, thereby improving the drying efficiency.

[0020] 2. The utility model starts multiple second fans and heaters. The second fans can suck external air into the interior of the heating box through the second air inlet pipe and the first air inlet pipe. After that, the air is heated by the heater and then transported to the wind collecting hood, the air outlet pipe and the interior of the air expansion hood in sequence. After that, the heated air will be transmitted upward layer by layer, so as to effectively dry the materials on the mesh conveyor belt. At the same time, the filter can prevent dust and other impurities in the air from entering the interior of the heating box. The air expansion hood can ensure that the materials can be sufficiently heated in all areas, thereby improving the overall practicality of the device. When the heated air gradually rises to the top of the shell after drying the materials, there will be a large amount of moisture in the air. At this time, the first fan can be started.
