Description

Technical Field

[0001] This utility model relates to the field of blasting engineering technology, specifically to an improved bulk explosive metering system. Background Technology

[0002] Bulk explosives are industrial explosives that are not pre-formed into fixed explosive packages and exist in the form of loose particles, powders, or pastes. They are mainly composed of ammonium nitrate, fuel oil, sensitizers, and other components. Compared with traditional packaged explosives, bulk explosives can be mixed and prepared on-site according to blasting needs, and have the characteristics of high flexibility, low cost, and high blasting efficiency. In the production and use process, special equipment is often used for dynamic mixing and quantitative transportation. They are widely used in large-scale blasting operations such as mining, water conservancy projects, and road construction. At the same time, due to the high sensitivity of bulk explosives and the stringent requirements for storage and transportation, strict safety regulations must be followed. Through full-process information management and explosion-proof technology, the safety and traceability of bulk explosives in the production, transportation, and use stages must be ensured.

[0003] In the existing technology, when explosives manufacturers repackage bulk explosives, they need to package them in quantitative quantities according to specifications. After delivery to the blasting site, they need to temporarily allocate the explosives to each work point according to the construction plan. During use, some static electricity will be generated when transporting the explosives. The explosives may cause danger due to the accumulation of static electricity. In addition, the explosives may clump together during the transport process, thereby blocking the feeding efficiency.

[0004] Therefore, an improved bulk explosive metering system was proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an improved bulk explosive quantitative dispensing system, which solves the technical problems of static electricity being generated during explosive transportation, which may cause danger due to the accumulation of static electricity, and the possibility of explosive clumping during the transportation process, thereby blocking the feeding efficiency. The system achieves the purpose of static electricity elimination and stirring to prevent clogging.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an improved bulk explosive quantitative dispensing system, comprising a conveyor platform, bottom legs fixedly connected to both sides of the bottom of the conveyor platform, a support fixedly installed on the top of the conveyor platform, a hopper fixedly installed between the inner walls of the support, an antistatic coating provided on the inner wall surface of the hopper, an antistatic elimination component provided on the top of the hopper, and a stirring anti-clogging component provided on the surface of the antistatic elimination component.

[0007] Preferably, the static elimination component specifically includes: a support plate, fixedly installed on the top of the hopper; a frame plate, with the support plate fixedly installed at equal intervals on the top; a bottom ring, fixedly installed on the top of the frame plate; a gear, disposed on the top of the support plate; and a hole block, fixedly installed at equal intervals on the top of the support plate.

[0008] Preferably, a rotating ring is rotatably connected to the top of the bottom ring, and a hollowed-out groove plate is fixedly installed on the top of the rotating ring. Connecting rods are fixedly installed on both sides of the gear one, and the other end of the connecting rods movably passes through the interior of the hollowed-out groove plate and extends to the top of the hollowed-out groove plate.

[0009] Preferably, the outer wall of the connecting rod is fixedly fitted with a convex sleeve, and the outer wall of the convex sleeve is provided with a slot at equal intervals around its circumference. The outer wall of the convex sleeve is slidably connected to the inner wall of the hollow groove plate, and the other end of the other connecting rod moves through the top of the support plate and extends to the bottom of the support plate. An antistatic rod is fixedly installed at the bottom of the connecting rod.

[0010] Preferably, a sliding rod is slidably connected to the inner wall of the hole block, a locking block is fixedly installed at one end of the sliding rod, a spring is movably sleeved on the outer wall of the sliding rod, one end of the spring is fixedly connected to one side of the hole block, and the other end of the spring is fixedly connected to one side of the locking block. The other side of the locking block engages with the inner wall of the locking groove. An external push plate is fixedly connected to the top of the locking block. By setting an antistatic coating on the inner wall of the hopper, static electricity generated by friction during explosive conveying can be reduced, thus reducing the risk of static electricity causing an explosion. The static elimination rod in the static elimination component can actively neutralize the charge on the surface of the explosive. With the rotation design of the rotating ring and connecting rod, it can cover the inside of the hopper in all directions, ensuring the effectiveness of static elimination, thereby achieving the effect of static elimination.

[0011] Preferably, the stirring anti-clogging component specifically includes: a sliding sleeve plate, movably sleeved on the outer wall of the support plate; a reduction motor, fixedly installed on the top of the sliding sleeve plate; a second gear, fixedly installed on the output end of the reduction motor; a cylinder, fixedly installed on the top of the support plate; an installation groove, circumferentially and equidistantly formed on the outer wall of the static eliminator; and a sliding groove, formed on both sides of the inner wall of the installation groove.

A locking block three is fixedly connected to the bottom of the locking block, and the outer wall of the locking block three engages with the inner wall of the locking groove three. The stirring and anti-clogging component drives gear two and gear one through a reduction motor, which drives the static elimination rod to rotate. At the same time, the stirring structure composed of the mounting strip and the locking block can break up the clumps of explosives in real time, ensuring uniform explosive flow and avoiding blockage. The cylinder pushes the sliding sleeve plate to move up and down, which can adjust the position of the reduction motor. The mounting strip engages with the locking groove two through the locking block two, and the locking block engages with the locking groove three through the locking block three. The compression spring assists in fixing, and the stirring structure can be quickly disassembled without tools, thereby achieving the effect of stirring and anti-clogging.

[0014] This invention provides an improved bulk explosive dispensing system. It offers the following advantages:

[0015] (1) This utility model can reduce the generation of static electricity by setting up a static elimination component. Explosives can be put into the hopper. When an object with static electricity approaches the static elimination rod, the static charge on the surface of the object will attract ions with opposite charges in the ion cloud. The antistatic coating on the inner wall of the hopper can also reduce the generation of static electricity, reduce the static electricity generated by friction during the transport of explosives, and reduce the risk of static electricity causing an explosion, thereby achieving the effect of static elimination.

The rotating ring 514 rotates on the bottom ring 513, and the stirring rod 617 stirs the discharge port of hopper 4 to prevent accumulation and blockage. The surface of stirring rod 617 and mounting strip 616 can be sprayed with an antistatic coating. When it is necessary to maintain the static elimination rod 519, firstly, the buckle block 6112 is pulled to drive the compression spring 6113 to compress, driving... The slider 6111 slides within the groove 619, the locking block 3 6114 separates from the locking groove 3, the mounting strip 616 is removed from the mounting groove 615, the locking block 2 618 separates from the locking groove 2, the starting cylinder 614 drives the sliding sleeve plate 611 to retract, causing gear 2 613 to separate from gear 1 516, then push the outer push plate 5115 with two fingers, causing the locking block 1 5113 and the sliding rod 5112 to move, compressing the spring 5114, the locking block 1 5113 separates from the locking groove 1, the connecting rod 517 and the convex sleeve 518 can be removed from the hollow groove plate 515, and then the gear 1 516 and the static elimination rod 519 are removed from the hollow groove plate 515.
