Description

Steam discharge device in a kind of ball mill
Technical field
The utility model belongs to the corollary equipment of ore grinding ball mill, relates to a kind of new ball mill steam exhaust device that can realize the outer row smoothly of steam in ball mill.
Background technology
Ball mill is divided into grate ball mill and overflowball mill according to ore discharge mode difference, be that to adopt prevailing be overflow type ore mill in current ore dressing plant, overflowball mill is primarily of the part such as cylindrical shell, end cap, base bearing, hollow axle journal, travelling gear and ore feeder composition.Ball mill can produce a large amount of steam in running, if got rid of not in time, organism temperature can be caused too high.The mode that in current ball mill, steam is discharged is still by adopting the principle of cold-hot air convection to carry out at the observation panel (as shown in Fig. 1, arrow bundle represents steam) in centre, nesting box front end, and such discharge mode mainly exists following problem:
1, produce a large amount of vapours in ball mill, only cannot thoroughly be discharged by observation panel;
2, vapours is hoarded in a large number in ball mill, ball mill organism temperature entirety is raised, is unfavorable for the safe operation of ball mill;
3, in ball mill, steam fills the air, and cannot observe inner ore grinding phenomenon by observation panel;
The steam of 4, being discharged by observation panel is directly come factory building inside, and post temperature is high, high humidity, and environment is poor.
Utility model content
In operation process, produce a large amount of steam and the problems referred to above brought to overcome ball mill, the utility model provides steam discharge device in a kind of ball mill.
The technical solution adopted in the utility model is: steam discharge device in a kind of ball mill, this ball mill comprises cylindrical shell, bowl mill quill shaft, nesting box, observation panel, inspiratory limbs is connected on nesting box top, the inspiratory limbs other end is connected on air-breathing supervisor, air-breathing supervisor is provided with blower fan, fan outlet is communicated with blast pipe, and the exhaust outlet of blast pipe is positioned at the outside of Brick wall.
Described nesting box top is inverted horn mouth shape, and inspiratory limbs is communicated with at horn mouth top closing place.
Described air-breathing supervisor is provided with simple and easy dust cleaning case, and simple and easy dust cleaning case fastens shimming by upper half chests, mould drag and is provided with filter cloth by bolted, inside again, mould drag bottom pyramidal, and the cone end is provided with can opening and closing outlet.
Described simple and easy dust cleaning case has two at least, is enabled, closes by Valve controlling.
Described filter cloth is located in half chests.
Described observation panel is provided with can opening and closing wicket, is of a size of 700mm × 1000mm, the gap of the little every limit of opening and closing and nesting box can adhere to sealing strip.
The exhaust outlet height of described blast pipe is higher than Brick wall height.
The beneficial effects of the utility model: in upwards central tendency when 1, steam is drawn onto bowl mill quill shaft position, thus by observation panel can see clearly the ore grinding phenomenon of ball grinder interior and the inner easy-abrasion part of nesting box whether intact;
2, by the getter action of centrifugal blower, by vapours in ball mill by discharging factory building by blower fan suction, making it to reach can exhaust steam, do not affect again the object of environment, and organism temperature entirety keeps stable;
3, in ball mill, steam is no longer come factory building inside, effectively improves post environment;
When 4, stopping, staff can enter into ball grinder interior from observation panel and works accordingly, greatly improves operating efficiency.
Accompanying drawing explanation
Fig. 1 is protocorm grinding machine steam exhaust device schematic diagram;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the amplification assumption diagram of simple and easy dust cleaning case of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is illustrated
As shown in Fig. 2: steam discharge device in a kind of ball mill, this ball mill comprises cylindrical shell 1, bowl mill quill shaft 2, nesting box 3, observation panel 6, inspiratory limbs 4 is connected on nesting box 3 top, inspiratory limbs 4 other end is connected on air-breathing supervisor 11, air-breathing supervisor 11 is provided with blower fan 8, blower fan 8 air outlet is communicated with blast pipe 9, and the exhaust outlet of blast pipe 9 is positioned at the outside of Brick wall 7.Starting blower fan 8 is disposed to outside factory building by ball grinder interior steam 5 extraction, blower fan produce negative pressure according to capacity number determine, can not be much, in order to avoid breeze is extracted out, the blower fan of different models or use more than two can be selected, also directly can utilize the original Fan Equipment of production system.
Can be inverted horn mouth shape by nesting box 3 substructure reconstruction, inspiratory limbs 4 be communicated with at horn mouth top closing place.Horn mouth shape as long-pending vapour device so that vapor stream smooth and easy.Inspiratory limbs 4 is fiberglass arm, and inspiratory limbs 4 adopts dog type rubber flexible joint to be connected to nesting box 3 top, damages inspiratory limbs 4 interface to prevent the vibrations because producing when ball mill runs.
In order to retain the mine dust be attached on steam, avoid waste, reduce environmental pollution, air-breathing supervisor 11 is provided with simple and easy dust cleaning case 12, as shown in Figure 3, simple and easy dust cleaning case 12 fastens shimming 12-3 by upper half chests 12-1, mould drag 12-2 and is provided with filter cloth 12-5 in, inside fastening by bolt 12-4 again, mould drag 12-2 bottom pyramidal, the cone end is provided with can opening and closing outlet 12-6.The fiber cloth that the optional compactness of filter cloth 12-5 is large, the rejection effect that obtain, the material that available sack cleaner cloth bag is used.Close the valve 13 on air-breathing supervisor 11, open the intake valve 14 of simple and easy dust cleaning case 12, filter cloth 12-5 just can retain mine dust, drops to mould drag 12-2 when gathering many, and upper mould drag is removable, reclaims mine dust or changes filter cloth.
Simple and easy dust cleaning case 12 has two at least, is controlled to enable, close, ensure that at least one works by valve 12-7, the operation just can carrying out reclaiming mine dust or changing filter cloth of not stopping like this.Filter cloth 12-5 is located in half chests 12-1, opens simple and easy dust cleaning case 12 and just can clear away the knoisphere be attached under filter cloth 12-5.
Observation panel 6 can be closed transparent window, and also can be provided with can opening and closing wicket.Needing the wicket opening observation panel 6 when observing ball grinder interior ore grinding phenomenon to observe, after observation, recover closed condition.This observation panel 6 is of a size of 700mm × 1000mm, and sealing strip is posted in the gap of little every limit and nesting box, ensures that ball grinder interior ore pulp can not overflow from the gap of observation panel 6.The wicket of observation panel 6 is normally closed condition, when inner ore grinding phenomenon observed by needs, observes, recover closed condition after observation outside the wicket station only need opening observation panel 6; In addition, after ball mill stops, personnel need to enter in cylindrical shell when carrying out checking or overhauling, and only need enter from observation panel 6, abandon the loaded down with trivial details flow process of carrying out follow-up work after being dismantled by nesting box 3 again, greatly improved operating efficiency.The exhaust outlet height of blast pipe 9 preferably higher than Brick wall 7 height so that exhaust steam 10 spreads in atmosphere immediately.
