Description

Allowable detonating cord making machine for coal mine

Technical Field

The utility model relates to an admissible detonating cord processing technology field in colliery specifically is an admissible detonating cord system cable machine in colliery.

Background

The explosion fuse for coal mine is one used in combustible gas or coal dust explosion environment and has the difference from common explosion fuse in that its coating layer contains flame suppressor.

At present, the method for adding the flame inhibitor into the allowable detonating cord coating layer of the coal mine has two methods:

the first method is a one-shot forming method. When the fuse making machine works, the explosive in the explosive hopper is driven by the core wire to pass through the explosive discharging nozzle and then be wrapped by the inner layer wire and the middle layer wire, the asphalt is adhered to the surface of the cotton wire after passing through the molten asphalt, the asphalt passes through the flame retardant groove, a certain amount of flame retardant is adhered to the surface of the asphalt and is wrapped by the kraft paper and the outer layer wire, and the plastic coating is carried out to prepare the allowable detonating fuse for the coal mine. The method has the disadvantages that the cable core is easy to condense at the outlet after passing through the asphalt pot to form asphalt lumps which are adhered on the cable core, when the cable core passes through the outer layer clamping die, the asphalt lumps are gathered at the edge of the third die core opening to reduce the inner diameter of the die core, and when the asphalt lumps pass through the outer layer clamping die, the cable section wrapped with asphalt, a flame retardant, kraft paper and an outer wrapping material cannot pass through and can be pulled off. In order to prevent the situation, the asphalt lumps adhered to the cable core need to be manually removed at any time, and man-machine isolation production cannot be realized; the cable core passes through the asphalt pot with high temperature, and when cable breakage occurs, the cable core can be processed after asphalt is cleaned, so that the operation is very complicated, and the production efficiency is low.

The second method is a two-step process. Firstly, during rope making, the core wire drives the explosive in the explosive hopper to pass through an explosive discharge nozzle and then is wrapped by an inner layer wire and a middle layer wire, and the rope core is made after coiling; and secondly, the manufactured cable core passes through a chemical feeding nozzle of a cable making machine, the cable making machine rotates, the cable core drives the flame suppressor in the chemical hopper to pass through the chemical feeding nozzle and then be wrapped by the outer layer wire, and the plastic coating is carried out to manufacture the explosion-conducting cable allowable for the coal mine. The method has the disadvantages that the production is completed in two steps, the first step is to complete the cable core part, and the second step is to coat the flame retardant on the cable core on the original cable making machine, so the process is repeated and complicated, and the production efficiency is low.
