Water removing method and water removing apparatus for high temperature emulsion explosive production line explosive cartridge

Abstract

The present invention discloses a water removing method for a high temperature emulsion explosive production line explosive cartridge, wherein an explosive cartridge conveyed out from a cooling water tank is subjected to vibration so as to make water beads attached on the explosive cartridge shed under an exciting vibration force effect, compressed air being subjected to drying heating is utilized to purge and heat the explosive cartridge being subjected to vibration dewatering to accelerate evaporation of the water on the explosive cartridge surface so as to achieve the water removing on the high temperature emulsion explosive production line explosive cartridge. According to the present invention, the explosive cartridge conveyed out from the cooling water tank is subjected to vibration so as to make the water removing rate on the explosive cartridge surface achieve 95%, and then the explosive cartridge being subjected to vibration dewatering passes through the compressed air heating dehumidifier so as to make the water removing efficiency achieve 98%, such that the dehumidifying effect is significant; after the explosive cartridge is subjected to water removing through the method of the present invention, the strength of the packaging carton can be reduced on the base of the existing packaging so as to reduce the manufacturing cost of the packaging carton; and the method of the present invention is simple and is easy to perform, the adopted apparatus has the low cost, the use is stable, and the effect is satisfactory.

Problems solved by technology

However, this production line is sensitive to high temperature, and its charging temperature is as high as 85°C-90°C. The formed drug rolls need to be fully circulated and cooled to 30°C-40°C in the pool through the belt before they can be sent to the packaging process and packed into boxes.

There is water on the surface of the cooled medicine roll, if the water cannot be removed well, it will easily lead to moisture regain and deformation of the medicine box after the medicine roll is packed

After understanding, many production enterprises have adopted methods such as adding axial flow fans above the subsequent conveyor belts, adding "air knives", and adding absorbent cotton cloth to remove water, but the results are not ideal

Because the water on the surface of the medicine roll is not well removed, the product packaging box is deformed due to moisture, or even collapsed

In order to solve the problem of moisture deformation of the packaging box, the company solves the problem of box deformation by increasing the strength of the packaging box body, which greatly increases the manufacturing cost of the packaging box
