Description

TECHNICAL FIELD

[0002] Cottonseed processing is to separate the short lint on the cottonseed from the cottonseed through the action of a machine, and the short lint is the main product, and the main components of the cottonseed short lint are organic compounds such as cellulose and hemicellulose, which have loose and porous structures and are extremely flammable. Although the cottonseed will be subjected to a stone removing and metal chip removing device before entering the workshop, some fine sandstone and metal chips may not be screened out, and the sparks generated by the friction and impact of the fine sandstone and metal chips can ignite the short lint, the flame can spread along the fiber gap to the depth, form smoldering, and it is not easy to be found, and it is easy to relight after extinguishing. Due to the flammable characteristics of the short lint itself, once a fire occurs, the fire spreads rapidly, and it is easy to form a large area and three-dimensional fire in a short time, causing difficulty in fire fighting. Due to the large fire load in the workshop, the temperature of the fire scene will be very high, the risk of building collapse will be greatly increased, which is not conducive to the attack of the fire brigade, and more fire water is needed to cool the fire scene temperature and block the spread of the fire. In addition, cotton has smoldering properties and must be slowly soaked with water, which requires a large amount of fire water, which further increases the difficulty of fire fighting.

[0003] In addition, although there is a spark detection device in the present lint removing workshop, there are certain limitations in the operation process. Once the spark is detected and an alarm signal is sent, manual checking of the alarm position is required, and the lint collecting pipeline has a small space and is inconvenient to operate. Generally, the short lint is sucked to the lint collecting machine by air, and then the spark is treated, which delays the treatment time and further increases the risk of fire.
