A fire safety device for producing porous granular ammonium oil explosives

Abstract

The utility model discloses a fire safety device for producing porous granular ammonium nitrate oil explosives, which belongs to the field of explosive production and comprises a crushing structure. A baffle is slidably mounted on the outer surface of a slide groove. Limiting strips are mounted on the outer sides of the baffle. In order to solve the problem that the amount of dust in a crusher is not detected, resulting in the crusher itself being extremely unsafe, extremely prone to explosion when encountering an open flame, and insufficient safety protection, explosive raw materials are poured into a material discharging frame, and a dust content sensor B arranged in a detection groove monitors the dust content in the discharge frame. When the dust content exceeds a set value, a driving motor is controlled to operate so that the forward and reverse thread screws are rotated, and the threads push two groups of movable threaded hole plates to approach each other, and the baffles are approached to each other in the slide groove, so that the flux space size in the discharge frame is reduced, and the feed size of the explosive raw materials is controlled, thereby controlling the dust content and preventing the open flame from accidentally igniting the explosive raw materials.

The products include: powdered ammonium oil-fuel mixture, porous granular ammonium oil-fuel mixture, heavy ammonium oil-fuel mixture, granular sticky explosive, and tackified granular ammonium oil-fuel mixture. Porous granular ammonium oil-fuel mixture can crush the explosive raw materials when manufacturing. In the publication number CN208843963U document, a kind of ammonium oil-fuel mixture production device is proposed, which can drive the first row of hoppers and the collection hopper to vibrate by arranging a vibrating mechanism, a double-shaft motor, a protective sleeve and a vibration block, and the products attached to the first row of hoppers and the collection hopper are all shaken off into the collection box, which not only avoids the waste of resources, but also prevents the occurrence of dangerous situations.

A detection groove 137 is provided on the inner wall of the row frame 13 and at the lower end of the movable threaded hole plate 136. A dust content sensor B138 is installed inside the detection groove 137. The inside of the detection groove 137 A blocking net B139 is installed near the middle end of the row frame 13, a dust content sensor A111 is installed inside the body of the crushing box 11 and at the lower end of the crushing roller 15, a blocking net A112 is installed on one side of the dust content sensor A111, an inclined strip 113 is installed inside the crushing box 11 and at the lower end of the blocking net A112, a circular frame 114 is installed at the bottom end of the inner part of the crushing box 11, a cylinder 115 is installed at the top of the circular frame 114, a mounting frame 1151 is installed at the moving end of the cylinder 115, a receiving frame 116 is threadedly installed at the bottom end of the mounting frame 1151, an adjustment motor 117 is installed on the outer surface of the crushing box 11, a rotating shaft 118 is installed at the output end of the adjusting motor 117, and a guide plate 119 is installed at the lower end of the rotating shaft 118.

[0026] In this embodiment, the explosive raw materials are poured into the discharge frame 16, and the dust content sensor B138 arranged in the detection slot 137 monitors the dust content in the row frame 13.
