[0021] 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.

[0022] In one embodiment, Figure 1-Figure 3As shown, the upper and lower circulating hot air uniform distribution type fireworks drying room includes a drying room body 1 and an air source heat pump main unit 2. The inner wall of the drying room body 1 is provided with a partition 7, and the partition 7 divides the drying room body 1 into an upper and lower layer. The upper layer of the drying room body 1 is a return air layer, and the lower layer of the drying room body 1 is a drying layer. The inner wall of the drying layer of the drying room body 1 is fixedly connected with a perforated air guide plate 6, and the perforated air guide plate 6 divides the drying layer of the drying room body 1 into a drying chamber and an air supply chamber. The air source heat pump main unit 2 is arranged outside the drying room body 1, and the side wall of the drying room body 1 is provided with a material door 9. The drying room body 1 is divided into an upper and lower layer by a partition 7. The upper layer of the drying room body 1 is a return air layer, and the lower layer of the drying room body 1 is a drying layer. The inner side wall of the drying layer of the drying room body 1 is fixedly connected with a punched air guide plate 6. The punched air guide plate 6 divides the drying layer of the drying room body 1 into a drying chamber and an air supply chamber, so that the hot air is evenly distributed in the drying chamber of the drying room body 1 in an upper and lower circulation. The hot air is evenly distributed on the cross section of the drying chamber and flows up and down, so that the material in the drying chamber is evenly dried.

[0023] In one embodiment, Figure 1 As shown, a dehumidifier is arranged in the return air layer of the drying room body 1, and a heat exchanger is arranged in the return air layer 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 dehumidified hot air to preheat fresh air.

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, where the refrigerant dissipates its heat to the air on the outer surface of the condenser, and then cools to become liquid.

[0026] In one embodiment, Figure 1 As shown, a plurality of ventilation holes are evenly distributed on the perforated air guide plate 6 to evenly supply air into the drying chamber.

[0027] In one embodiment, Figure 1 and Figure 2 As shown, the width of the return air layer of the drying room body 1 is greater than half of the width of the drying chamber.

[0028] In one embodiment, Figure 1As shown, a plurality of return air vents are arranged on the side wall of the partition 7, a dustproof net 8 is arranged at the return air vent of the partition 7, and two fresh air vents are opened on the side wall of the return air layer of the drying room body 1, and air valves 3 are arranged in both fresh air vents.

[0029] In one embodiment, Figure 1 and 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.

[0030] The above embodiment discloses a firework drying room with evenly distributed hot air circulating upwards and downwards. The utility model divides the drying room body 1 into two layers, the upper layer of the drying room body 1 is a return air layer, and the lower layer of the drying room body 1 is a drying layer. The inner side wall of the drying layer of the drying room body 1 is fixedly connected with a perforated air guide plate 6. The perforated air guide plate 6 divides the drying layer of the drying room body 1 into a drying chamber and an air supply chamber, so that evenly distributed hot air is formed in the drying chamber of the drying room body 1, so that the hot air is evenly distributed on the cross section of the drying chamber and flows up and down, and the material in the drying chamber is evenly dried;

[0031] The return air layer is equipped with a dehumidifier and fresh air inlet.
