Description

Ventilation telescopic pipeline device for coal storage Euro bin

Technical Field

The utility model belongs to the technical field of the Euro storehouse and specifically relates to a store up coal Euro storehouse with flexible pipe installation that ventilates is related to.

Background

The Euro coal storage is the latest domestic environment-friendly coal storage mode, but the situation of coal storage is greatly different because the coal types used by the Euro coal storage are greatly different from those used in China. The coal used in China at present has high water content (the sum of internal water and external water can reach more than 30%), a large amount of volatilized water vapor and various gases generated by coal oxidation are dissolved together to form acidic substances which are adhered to the surfaces of various devices and metal structures in a bin, and the generated corrosion and rust seriously damage the service life and the structural safety of the devices.

In addition, toxic and harmful gas volatilized by coal accumulated in the Euro bin not only can generate fire hazard, but also can harm the personal safety of overhaul and operating personnel entering the bin.

In order to reduce the oxidation of coal in the bunker or avoid spontaneous combustion, nitrogen is released into the coal in the bunker to prevent the oxidation of the coal for the safety of coal storage, but the nitrogen is inevitably released and is diffused into a space which is not piled with coal in the bunker, so that the oxygen content in the air above the coal pile in the bunker is reduced, and therefore, people are required to enter the bunker quickly for treatment, and the danger of suffocation caused by too low oxygen concentration exists.

As shown in fig. 2, although two sets of first fans 16 are arranged on the roof and 15 of the euro bunker, the actual exhaust effect is poor, mainly because various gases and water vapor are generated and mainly collected in the area near the upper surface of the coal pile in the bunker. The gas in the area near the main fan and discharged by the first fan 16 mounted on the top cover 15 of the euro silo, and the top cover 15 of the euro silo is not a sealed container, various gaps always exist between the top cover 15 and the barrel 1 at various structural joints of the euro silo, so that the gas can enter the silo and then flow to the first fan 16 to be discharged by the first fan 16, because the gas flow always occurs from the place with the smallest resistance, the gas flow efficiency from bottom to top is very low, so that the upward flow speed of the gas close to the coal pile is very slow, especially in the condition that the height of the coal pile in the euro silo is low, namely the stored coal amount is small, when the distance between the surface of the coal pile and the first fan 16 of the top cover 15 is long, the air discharge effect of the first fan 16 is poor, according to practical observation, the time of at least 10 hours is required for completely replacing the gas in the silo, and the restriction of the storage operation of the personnel can also affect the safety of the euro silo in time, and the safety of the production of the euro silo can be seriously affected.

As shown in figure 1, in order to realize the functions of coal warehousing and stacking and coal discharging and taking, a set of complete coal entering and exiting stacking equipment is arranged in the Euro silo, and mainly comprises a rotary trestle 4, a trestle walking mechanism 5, a central rotary platform 13, a central telescopic blanking pipe 6, a spiral frame 8, a spiral machine 9, a spiral frame A-shaped frame 11 and the like, wherein a coal conveying trestle 3 is arranged at the top of the Euro silo, a belt conveyor is arranged in the trestle, and coal is conveyed to an inlet of the central telescopic blanking pipe 6 at the upper part of the Euro silo by the conveyor and then enters the Euro silo through the central telescopic blanking pipe 6. The spiral stacking device pushes coal out to be laid flat, so that the coal is stacked up layer by layer, meanwhile, the rotary trestle 4 is driven by the trestle travelling mechanism 5 to do circular motion on a horizontal plane fixed in a bin, the spiral frame A-shaped frame 11 is hung on the rotary trestle 4 through the spiral frame lifting steel wire rope 7 and rotates along with the rotation of the rotary trestle 4, the hung steel wire rope enables the spiral frame A-shaped frame 11 to do lifting motion through the winding device, the requirement that the stacking is achieved, the spiral frame A-shaped frame 11 changes along with the change of the coal stacking height all the time is met, the central telescopic blanking pipe 6 is formed by concentrically connecting a plurality of sections of round pipes with different diameters, the round pipes between every two adjacent sections are mutually hooked and cannot be separated, and can relatively slide along the axial direction of the barrel body, the structure enables the whole set of telescopic blanking pipe to expand or contract section by section along with the extension or shortening of the distance between two ends, the telescopic length can meet the requirement that the distance between the rotary trestle 4 and the spiral frame A-shaped frame 11 changes, and the materials are ensured to always pass through the central telescopic blanking pipe 6. Therefore, the area between the rotary trestle 4 and the spiral frame A-shaped frame 11 in the Euro bin is the space occupied by equipment operation, obviously, fixed ventilation pipeline equipment cannot be arranged in the space, and except for a bin top fan, the existing coal storage Euro bin has no corresponding ventilation device to meet the requirement of quick and efficient ventilation.
