[0030] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.
[0031] The multifunctional mining fan mesh cover assembly device as shown in the figure includes: a wind cover barrel, a baffle plate, an explosion-proof baffle 9, an anti-oxidation baffle 10 and an activated carbon baffle 11. The baffle is installed on the wind cover barrel, and the wind cover barrel is installed at the fan outlet. The wind cover barrel raises the fan outlet to 20 cm to prevent operators from inserting their fingers and getting entangled.
[0032] The wind hood barrel includes a barrel body and a fixing plate. A connecting plate 6 is arranged at the bottom of the barrel body. A plurality of connecting holes are correspondingly provided on the connecting plate 6 and the fan outlet. The wind hood barrel is installed at the fan outlet through the connecting nut 5 and the connecting hole. A limiting rod 61 is arranged at the edge of the connecting plate 6. A limiting groove is formed between the limiting rod 61 and the barrel body. The unused baffles can be placed in the limiting groove to complete the storage and arrangement of the baffles, thereby preventing the unused baffles from being lost.
[0033] The fixing plate is a semicircular ring structure, which is arranged on the top of the barrel body, and includes a first fixing plate 1 and a second fixing plate 3. The circumference of the first fixing plate 1 is longer than that of the second fixing plate 3. The first fixing plate 1 is fixedly arranged on the barrel body, and the second fixing plate 3 is detachably installed on the top of the barrel body through a fixing nut 4. A baffle placement groove 2 is provided on the top of the barrel body. The baffle placement groove 2 is a groove with a certain height, and the groove is recessed toward the inner side of the barrel body. The baffle is limitedly placed in the baffle placement groove 2, and the top is clamped and fixed by the fixing plate. When installing the baffle, remove the second fixing plate 3, insert the baffle horizontally into the bottom limit of the first fixing plate 1 and place it in the baffle placement groove 2, and then install the second fixing plate 3 and lock it through the fixing nut 4. At this time, the baffle is limitedly fixed by the first fixing plate 1 and the second fixing plate 3.
[0034] The baffles include a baffle plate, an explosion-proof baffle plate 9, an anti-oxidation baffle plate 10 and an activated carbon baffle plate 11. The baffle plates are inserted and installed in the baffle placement slot 2. The baffle plates are replaced according to different usage scenarios to achieve the desired purpose. The baffle plate includes a mesh baffle plate 7 and a radial baffle plate 8. The mesh baffle plate 7 is made of 6mm thick steel bars with a mesh size of 3cm*3cm. The baffle plate has been greatly optimized on the original wind hood, so that the fan mouth shielding area is reduced from about 50% to about 15%, greatly reducing the ventilation resistance.
[0035] When underground blasting operations are performed, explosion-proof baffles are used. The explosion-proof baffles are made of 10mm thick steel bars and have a mesh size of 2cm*2cm. They protect the fan from shock wave damage while preventing flying rocks from entering the fan.
[0036] The anti-oxidation baffle 10 is a sealed circular baffle composed of calcium oxide and iron wire, which can form a seal at the fan outlet to prevent moisture from entering the fan, greatly prevent idle fans from being oxidized in the humid and high temperature environment underground, and increase the service life of the fan.
[0037] When toxic and harmful gases in the well need to be treated and removed, an activated carbon baffle 11 is used. The activated carbon baffle 11 is a double-layer mesh structure made of activated carbon. It adsorbs toxic and harmful gases in an environment where toxic and harmful gases need to be treated urgently. The activated carbon can adsorb 90% of H2S at the ppm level.
[0038] Finally, it should be noted that, in this article, relationships such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms include, include or any other variations are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0039] The units described as separate components may or may not be physically separated, and the components shown as units may or may not be physical units, that is, they may be located in one place or distributed on multiple network units. Some or all of the units may be selected according to actual needs to achieve the purpose of the solution of this embodiment.
