Description
Technical Field
[0001] The utility model relates to the technical field of mosquito coil drying, in particular to a heat pump drying type mosquito coil heating system. Background Art
[0002] Mosquito coils are medicinal items that can repel mosquitoes, kill bacteria, and prevent insect pests. They have long been a must-have for consumers to repel mosquitoes in summer and autumn. However, the production process and processing technology of mosquito coils are relatively high, especially the drying of mosquito coils. During production, the raw materials are generally mixed with water and stirred evenly, then pressed into wet blanks and punched into molds, and then sent to the drying room for drying with hot air. The drying room is generally built in a long strip with varying lengths. In actual production, the wet blanks of mosquito coils are placed on grid-type shelves, and the shelves are stacked in a simple transport vehicle, which is then sent to the drying room for drying mosquito coils. Traditional mosquito coil drying usually adopts countercurrent drying method, and the general air supply temperature is above 80℃. During the drying process, the air moisture content at the return air of the feeding section is high, and the dehumidification capacity is low. If the dehumidification capacity of the air at the return air is to be improved, the air supply temperature must be increased or the air supply volume must be increased. At the same time, traditional mosquito coil drying generally uses coal or gas as energy to heat the air, and there are still problems such as high energy consumption and serious environmental pollution. Heat pump is a highly efficient and energy-saving technology. It uses the reverse Carnot principle to convert part of low-grade energy into high-grade energy by consuming high-grade energy, thereby achieving energy improvement and improving the dehumidification capacity per unit energy consumption. Heat pump drying technology is now widely used in the wood industry, textile, food and agricultural product processing industries. Therefore, applying heat pump technology to mosquito coil drying can reduce or solve the high energy consumption and high pollution problems in mosquito coil drying.
[0003] In the existing drying room, during the mosquito coil drying process, the air duct is fixedly installed, so that the hot air blown out from the air duct is unevenly distributed in the drying room, with a larger air volume below the air duct and a smaller air volume in the center, resulting in uneven heating of the mosquito coils on the material rack in the drying room, affecting the quality of the finished mosquito coils.

[0033] Please refer to Figure 1 and Figure 2, a heat pump unit 4 is installed at the top of the drying chamber body 1, air ducts 5 are installed on both sides of the heat pump unit 4, and the air ducts 5 are connected to the drying chamber body 1. The drying chamber body 1 is of a tunnel type. Stainless steel heat-insulating doors 2 are installed at both ends of the drying chamber body 1. Sliding tracks 3 are laid at the bottom of the drying chamber body 1. A material rack 8 is placed on the sliding tracks 3 inside the drying chamber body 1, and the material rack 8 is slidably connected to the sliding tracks 3. Two air supply openings 6 are provided at the top of the drying chamber body 1, and the air supply openings 6 are communicated with the air ducts 5. An air return opening 7 is provided at the top of the drying chamber body 1, and the air return opening 7 is communicated with the heat pump unit 4.
[0034] Working principle: First, the mosquito coil raw materials are mixed, added with water, stirred evenly, then pressed into wet blanks and formed by punching. Then they are placed on the material rack 8 and enter the inside of the drying chamber body 1 through the sliding tracks 3 for drying. The drying chamber body 1 is long. Then the heat pump unit 4 starts to send out hot air through the air ducts 5, and the hot air is sent out simultaneously from the two air supply openings 6 and returns from the air return opening 7 in the middle. Then the heat pump unit 4 starts to send out hot air through the air ducts 5. The heat pump unit 4 is composed of a compressor, two condensers, two evaporators, two air supply fans, and a control system. The heat pump drying technology is mature and has been widely applied, and it is not the novelty of this application, so it will not be described in detail.
