Embodiment 1

[0044] As shown in the accompanying drawings, a non-metallic blocking explosion suppression ball includes: an upper tubular structure 1, a lower tubular structure 2, an arcuate sheet 3, an annular sheet 4 and a circular sheet 5, an upper tubular structure 1, a lower tubular structure 2, an arcuate sheet Sheet 3, annular sheet 4 and circular sheet 5 form a hollow grid-shaped sphere;

[0045] The upper tubular structure 1 and the lower tubular structure 2 are respectively arranged at the upper and lower ends of the sphere and are coaxial with the sphere;

[0046] The number of the arcuate pieces 3 is four, which are symmetrically arranged around the upper tubular structure 1 and the lower tubular structure 2, the two adjacent arcuate pieces are perpendicular to each other, and the chords of the arcuate pieces 3 are The structure 2 is fixedly connected, and the arc of the arcuate piece 3 constitutes the warp of the sphere;

[0047] The number of the annular sheets 4 is four, and...

Embodiment 2

[0057] Same as Example 1, the difference is only:

[0058] The composition of the explosion-suppressed sphere material includes the following components:

[0059]

Embodiment 3

[0061] The sphere structure is the same as in Example 1,

[0062] The composition of the explosion-suppressed sphere material includes the following components and weight percentages:

[0063]

[0064] Weigh each component according to the above weight percentage, mix antioxidant, carbon black and nylon 66 masterbatch in a high-speed mixer for 3 minutes, then put it into a twin-screw extruder together with carbon fiber for granulation, and carbon fiber is extruded by extruding The auxiliary feeding port of the machine is added. The twin screw adopts SHF-30 type produced by Nanjing Jiente Electromechanical Co., Ltd. The speed of the screw machine is 450 rpm, and the temperature of each section of the extruder is controlled as follows: the barrel temperature is 240 °C in the first zone, 245 °C in the second zone, 260 °C in the third zone, 265 °C in the fourth zone, 265 °C in the fifth zone, and 265 °C in the die head. .

Abstract

The invention discloses a nonmetal separating explosion suppression ball. The ball comprises an upper tubular structure, a lower tubular structure, four arched pieces, 3 to 5 annular pieces and two circular pieces, wherein the upper tubular structure, the lower tubular structure, the arched pieces, the annular pieces and the circular pieces form a hollow grid-shaped ball body; the upper tubular structure and the lower tubular structure are respectively arranged at the upper and lower ends of the ball body and coaxial with the ball body; the arched pieces are symmetrically arranged at the peripheries of the upper tubular structure and the lower tubular structure; and the annular pieces are vertically inserted into the arched pieces along the axis of the ball body. The ball has the advantages that the ball is long in service life and not required to be replaced, the stability of the ball in a flammable and explosive chemical is relatively high, debris and residues do not exist, the mechanical property is relatively high, phenomena such as collapse are avoided, and the ball is easy and convenient to disassemble.

Description

technical field [0001] The invention relates to the technical field of blocking explosion suppression, and furthermore, relates to a non-metallic blocking explosion suppression ball. Background technique [0002] In containers containing gasoline, diesel oil, acetylene and other liquids, due to the existence of the mixture of vapor and air of these volatile substances, it is very easy to burn and explode. Explosion suppression technology is a kind of technology that can effectively prevent the explosion of flammable and explosive gaseous and liquid hazardous chemicals caused by accidents (static electricity, welding, gunshots, collisions, wrong operations, etc.) The proprietary technology of intrinsic safety in the storage and transportation of explosive liquid and gaseous hazardous chemicals is referred to as HAN (Hypostasis Anchor-hold No-expolosion), which means intrinsically safe and non-explosive. [0003] In the 1960s, the United States began to use polyurethane foam ...
