specific Embodiment approach 2

[0043] refer to figure 1 As shown, the embodiment is a bag-shaped mining equipment explosion-proof, fire-proof, dust-proof and noise-proof device made of soft materials. The mining equipment (4) is installed in a flexible fire-proof isolation bag (3), and the mining equipment (4) is wrapped to form a A relatively sealed equipment space is provided, and there is one or several exhaust ports (2) on the upper part of the fireproof isolation bag (3). The exhaust ports (2) are made of copper mesh, stainless steel mesh, barbed wire, asbestos cloth, glass fiber cloth, etc. The flame retardant isolation net (1) made of flame retardant material is used for fire isolation, carbon dioxide or nitrogen is added to the fire isolation bag, and the flammable combustion-supporting gas inside the fire isolation bag is discharged from the upper isolation net to form a non-flammable and non-explosive Safe and small environment, to achieve the purpose of explosion-proof, fire-proof, dust-proof and...

specific Embodiment approach 3

[0044] figure 2 As shown, the embodiment is a box-type mining equipment explosion-proof, fire-proof, dust-proof and noise-proof device made of hard materials. The mining equipment (4) is installed in the box (3) made of hard materials, and the mining equipment (4) is surrounded. A relatively sealed equipment space is formed. There is one or several exhaust ports (2) on the upper part of the box (3) made of hard materials. The exhaust ports (2) are made of copper mesh, stainless steel mesh, barbed wire, asbestos cloth, The flame-retardant isolation net (1) made of flame-retardant materials such as glass fiber cloth is used for fire-proof isolation. Carbon dioxide or nitrogen is added to the box made of hard materials, and the flammable combustion-supporting gas inside the box made of hard materials is released from the upper part. The isolation net is discharged to form a safe small environment that is not combustible and non-explosive, and achieves the purpose of explosion-pr...

specific Embodiment approach 4

[0045] figure 1 As shown, the embodiment is a room-type mining equipment explosion-proof, fire-proof, dust-proof and noise-isolation device made of hard materials. On and around the top of the equipment (4), a relatively sealed equipment space is formed. There is one or several exhaust outlets (2) on the upper part of the room-type fireproof isolation device (3), and the exhaust outlets (2) are covered with copper mesh. , stainless steel mesh, barbed wire, asbestos cloth, glass fiber cloth and other flame-retardant materials. It is discharged from the upper isolation net to form a safe small environment that is non-combustible and non-explosive, achieving the purpose of explosion-proof, fire-proof, dust-proof and noise-proof.

Abstract

The invention provides an anti-explosion, fireproof, dust-proof and noise-proof protecting device for mine equipment in terms of mine equipment protection and for the purpose of simplicity and practicability. The device is low in cost, simple in structure, and convenient and reliable to use, and can be used for large, medium and small mines. The device comprises three types: (1) the first type of device is made of airtight materials, and the anti-explosion, fireproof, dust-proof and noise-proof purposes are achieved by complete isolation; (2) the second type of device is made of materials with certain breathability or certain breathability partially, inflammable and combustion-supporting gas in an isolation device can be expelled from the breathable materials at the upper part, a non-inflammable and non-explosive safe microenvironment is formed, and the anti-explosion, fireproof, dust-proof and noise-proof purposes are achieved; and (3) the third type of device is made of airtight materials, an air outlet is formed on the isolation device so as to ensure that the inflammable and combustion-supporting gas in the isolation device is expelled from the air outlet at the upper part, a non-inflammable and non-explosive safe microenvironment is formed, and the anti-explosion, fireproof, dust-proof and noise-proof purposes are achieved.

Description

technical field [0001] The invention belongs to the field of mining equipment, and in particular relates to an explosion-proof, fire-proof and dust-proof equipment used in gas, hydrogen and other environments, and a protection device for explosion-proof, fire-proof and dust-proof. Background technique [0002] China's mine disasters are 100 times that of the United States, and the death toll accounts for 80% of the world's total. In China, not only coal mines, but also many other mines have inadequate safety settings, and equipment problems are also prominent: mine owners do not follow the regulations to invest in safety. From the perspective of mining conditions, the overall technical status of coal mines is relatively backward, and state-owned coal mines are mechanized. Although the level has reached 60% to 70%, a large number of township coal mines have a low degree of mechanization and backward equipment, and some still use primitive mining methods. They do not pay atten...
