[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0023] In one embodiment, Figure 1-Figure 3As shown, the left-right circulating advection hot air fireworks and firecrackers drying room comprises a drying room body 1 and an air source heat pump main unit 2. The air source heat pump main unit 2 is arranged outside the drying room body 1. The side wall of the drying room body 1 is provided with a material door 8. The drying room body 1 is divided into a drying chamber and an air supply chamber. The inner side wall of the drying chamber is fixedly connected with a partition wall 7. The partition wall 7 divides the drying chamber into an air inlet chamber and a return air chamber. In the utility model, the drying chamber of the drying room body 1 is divided into a drying chamber and an air supply chamber. The drying chamber is divided into a left chamber and a right chamber by a partition wall 7. The left chamber is the air inlet chamber and the right chamber is the return air chamber. The left-right circulating advection hot air is formed in the drying chamber, so that the hot air is evenly distributed on the longitudinal section of the drying chamber of the drying room and flows left and right, and the materials in the drying chamber are evenly dried, thereby improving the drying efficiency of the fireworks and medicine materials. In addition, the wind force and wind speed are gentle and will not cause dust to fly, thereby effectively improving the safety of the drying room body 1.
[0024] In one embodiment, Figure 1 As shown, the air inlet cavity of the drying room body 1 is connected to the air supply cavity through the guide plate 4 and the wind wall 3.
[0025] In one embodiment, Figure 1 and Figure 2 As shown, a plurality of fans are installed on the wind wall 3, and the fans are evenly distributed on the wind wall 3. This is beneficial for even distribution of hot air on the longitudinal section of the drying chamber of the drying room.
[0026] In one embodiment, Figure 1 As shown, a plurality of ventilation holes are evenly arranged on the guide plate 4, which is conducive to the uniform distribution of hot air on the longitudinal section of the drying chamber of the drying room. The ventilation holes make the wind speed of the fan gentle and will not cause dust to fly, effectively improving the safety of the drying room body.
[0027] In one embodiment, Figure 1 As shown, a dustproof net 6 is arranged in the return air cavity of the drying room body 1 to prevent dust from entering.
[0028] In one embodiment, Figure 1 and Figure 2 As shown, a condenser 5 is arranged in the return air cavity of the drying room body 1, and the return air cavity of the drying room body 1 is connected to the supply air cavity through the dustproof net 6 and the condenser 5. When the refrigerant is discharged from the compressor of the heat pump and enters the condenser, it flows in the pipelines, which are in a high temperature and high pressure state, and the refrigerant dissipates its heat here to the air on the outer surface of the condenser, and then cools to become liquid.
[0029] In one embodiment, Figure 1 As shown, a dehumidifier, a fresh air outlet, and a heat exchanger are provided in the drying room of the drying room body 1. The heat exchanger is used to transfer heat from hot fluid to cold fluid, and the heat exchanger uses the dehumidified hot air to preheat the fresh air.
[0030] In one embodiment, Figure 1and Figure 2 As shown, a movable material trolley is provided in the drying chamber of the drying room body 1. The movable material trolley is used to evenly distribute the materials in the drying chamber.
[0031] The above-mentioned embodiment discloses a left-right circulating horizontal hot air drying room for fireworks and firecrackers. In the utility model, the drying chamber of the drying room body 1 is divided into a drying chamber and an air supply chamber. The drying chamber is divided into a left chamber and a right chamber by a partition wall 7. The left chamber is an air inlet chamber and the right chamber is a return air chamber. Left-right circulating horizontal hot air is formed in the drying chamber, so that the hot air is evenly distributed on the longitudinal section of the drying chamber of the drying chamber and flows left and right, so as to evenly dry the materials in the drying chamber, thereby improving the drying efficiency of the fireworks and medicine materials, and the wind force and speed are gentle and will not cause dust to fly, thereby effectively improving the safety of the drying room body 1; improving the drying efficiency is beneficial to saving electric energy and being more environmentally friendly.
[0032] A movable material cart is used to evenly distribute the materials in the drying chamber.
