Fireworks Dryer

Abstract

The invention discloses a fireworks dryer. The fireworks dryer comprises a machine body, a heat source system, a dehumidifying system and a multilayer heat conducting material frame; each heat conducting layer of the multilayer heat conducting material frame is communicated by pipes back and forth; a hot water or hot air inlet and a hot water or hot air outlet of each heat conducting layer are communicated by pipes; and a master hot water or hot air inlet and a master hot water or hot air outlet of the multilayer heat conducting material frame are communicated with the heat source system. The fireworks dryer has the advantages of large shortening of the drying time, high production efficiency, low energy consumption, small difference of material drying curves in different positions and good drying quality; no steam water drop is in the top of the machine body; and the safe opening, closing, locking and unlocking of a mobile door and the material accessing of an intelligent trailer are remotely controlled to prevent accidents.

Description

technical field [0001] The invention relates to a fireworks production equipment, in particular to a fireworks dryer. Background technique [0002] In the production of fireworks, fireworks raw materials such as drugs, bright beads, and lead wires must be dried, and most of them use the drying method of traditional drying rooms. Chinese Patent Announcement No. CN 101936643 B discloses "fireworks and firecrackers drying room with air source heat pump as heat source", announcement number CN 204630261 U discloses "a kind of pyrotechnic powder drying system", and announcement number CN 100436383C discloses "heat pump type gunpowder drying system". Drying method and device", the patents such as "a method and device for dehumidifying and drying fireworks firecracker powder" disclosed by the notification number CN 101348402 B all place the materials on one or more layers of air-permeable bottom plates, and the hot air passes through the materials to dry. The drying time of these e...

AI Technical Summary

Problems solved by technology

The drying time of these equipment is long, the production efficiency is low, the energy consumption is large, and the drying curves of materials in different positions are very different, some dry quickly, and some dry slowly

The top of the drying room is also prone to form water droplets and fall on the materials, which affects the drying quality. On the other hand, the fireworks raw materials must be cooled before unloading after drying, and the next batch of raw materials can enter the drying room. Otherwise, it is flammable and explosive, which will cause personal safety. ACCIDENT

However, the current drying room has good thermal insulation, and it takes a long time to cool down, which affects production efficiency.
