Embodiment 1

[0014] See this example figure 1 As shown, during the grinding operation, the operator weighs a 5g TNT equivalent sample, places the sample in the mortar 7, and fixes it in the upper frame of the lifting platform 8, wherein the lifting platform is an aluminum-magnesium alloy lifting platform of 20cm*20cm , by adjusting the aluminum-magnesium alloy lifting platform 8 to make the mortar in the best grinding position, the grinding rod is made of a wooden grinding rod 4, a 5mm thick titanium alloy lower protective plate 5 and an agate grinding head 6 with a diameter of 110mm. The materials of horizontal protective plate 1, vertical protective plate 3 and protective bottom plate 2 are all 10mm thick carbon steel. The operator is located on one side of the vertical protective plate 3, passes through a circular opening with a diameter of 55mm at the horizontal protective plate 1, wears anti-scald gloves, holds the grinding rod 4 for grinding, and the inner side of the vertical protec...

Embodiment 2

[0017] See this example figure 2 As shown, during the grinding operation, the operator weighs 5g of TNT equivalent sample, places it in the mortar 7, and fixes it in the upper frame of the aluminum-magnesium alloy lifting platform 8, wherein the lifting platform is a 20cm*20cm aluminum-magnesium alloy lifting platform. Platform, make the mortar be in the best grinding position by adjusting the lifting platform 8, the grinding rod is made of wooden grinding rod 4, 10mm thick diameter explosion-proof glass lower protective plate 5 and agate grinding head 6 of 110mm. Horizontal protective plate 1 and vertical protective plate 3 are made of transparent explosion-proof glass with a thickness of 10 mm. The operator is located on one side of vertical protective plate 3 and passes through the circular opening with a diameter of 55 mm in horizontal protective plate 1. Wear anti-scald gloves and hold The grinding rod 4 is ground, and the grinding process is observed through the explosi...

Abstract

The invention belongs to the field of dangerous goods protection equipment and discloses an explosion-proof safety grinding device. The device exerts a protection effect against an explosion wave, a combustion heat wave and splash of broken residues of a built-in device, and is applicable to dispersion and grinding of small dose flammable and explosive dangerous goods required by a scientific experiment. The device mainly comprises a protection system, a grinding system and a visual observation system; the protection system comprises a protection housing and sand boxes on the two sides; the grinding system comprises an aluminum-magnesium alloy lifting platform, a grinding rod, a lower protection plate, a sectional material and a mortar; and the visual observation system is an image transmission device (a camera, a bracket, a signal transmission device and a display screen) or an observation window. The device is simple to operate, low in cost, safe and reliable, convenient to manufacture and easy to popularize and apply.

Description

technical field [0001] The invention relates to a grinding device, which belongs to the field of protective equipment for dangerous goods. Background technique [0002] In the research field of explosives and other dangerous goods, grinding materials is a very important and indispensable step. However, these materials generally have high energy, high power, flammability, and explosive characteristics. , will cause combustion or explosion due to friction, impact, static electricity and other reasons. The heat energy and high-temperature and high-pressure gas generated will damage, throw, and compress the surrounding materials. Grinding operations without protective measures are extremely It is easy to cause damage to peripheral equipment or operator casualties. Patent CN107328624A discloses a safety shield for explosive grinding operation, which has the disadvantage that it cannot effectively protect the hands of the operator, and the control of the accuracy of the grinding ...
