Abstract
The utility model discloses an internal dust exhaust device of a jaw crusher. An feeding hole of the jaw crusher is sealed by a soft curtain, a movable cover plate is arranged at the upper part of the jaw crusher, a discharge hole chute of the jaw crusher is sealed by a soft curtain, and a dust collection point is positioned at a breaking dust production point of the jaw crusher and is formed in a manner that a dust exhaust cover is arranged between the discharge hole chute and the soft curtain and is connected with a dedusting system through a dust gas pipe. A dust exhaust method of the jaw crusher provided by the utility model can be used for exhausting dust efficiently, is high in airtightness, requires a small amount of negative pressure and small air volume, and facilitates maintenance and operation of the crusher. The device for implementing the internal dust exhaust method is simple in structure and reliable in performance.
Description
Technical field
The utility model relates to a kind of jaw crusher, particularly relates to the inner dust exhaust of a kind of jaw crusher.
Background technology
The coarse crushing that jaw crusher is widely used in various ores and bulk materials in the industries such as mine selecting and purchasing, building materials, highway, railway, water conservancy and chemical industry with in broken in, be a kind of conventional disintegrating apparatus.In the continuous process of broken material, generation is escaped to dust in a large number, the mechanism of production of dust has following three aspects: (1) material is directly dropped to the recoil air-flow producing in machine by charging aperture, takes away part dust and is escaped by charging aperture; (2) the movable liner plate of the jaw crusher generation high pressure draught that runs up, takes away broken dust and escapes from the low-pressure area of feed opening; (3) between the chute of feed opening and belt, there is the shear action that certain altitude is poor and belt runs up to air, can will in material, carry dust proliferation secretly.
Escape dust and spread in workshop, operating personnel have been brought to certain occupational hazards.Although enterprise is used dust pelletizing system to carry out treating flour dust to jaw crusher at present, the following Fig. 1 signal of improvement method (arrow is that air-flow moves towards signal), but the method is not in order to affect operating personnel's observation, adopt outside hood to carry out dust discharge, because equipment and hood do not have airtight, it is far away that dust sucting point produces dirt pits apart from fragmentation, cause Air Quantity Required and negative pressure larger, cause the required energy consumption of cleaner high, but still dust discharge weak effect, there are a large amount of dust to escape from the chute of feed opening, adopt which dust discharge also to affect the normal maintenance of jaw crusher, think a large difficult point of current jaw crusher treating flour dust.
Patent content
Technical problem to be solved in the utility model is to provide the inner dust exhaust of jaw crusher that the efficient dust discharge of a kind of energy, strong, the required negative pressure of seal and air quantity are little, be convenient to disintegrating machine maintenance, operation.
In order to address the above problem, the inner dust exhaust of jaw crusher that the utility model provides, comprise jaw crusher and feed opening chute, above the charging aperture of described jaw crusher, be provided with movable closed cover plate, on described movable closed cover plate and be provided with the soft curtain of the first suspension between feed belt, in described feed opening chute, be provided with the soft curtain of the second suspension, on described feed opening chute, be provided with hood in the described second position hanging between soft curtain and described jaw crusher, described hood is connected with dust pelletizing system by dirt tracheae.
Adopt the inner dust exhaust of jaw crusher of technique scheme, the first soft curtain of suspension and second hangs soft curtain and has sealing function, when work, material is delivered to and in jaw crusher working chamber, is carried out fragmentation by the soft curtain of the first suspension by feed belt, operating personnel observe by the movable closed cover plate of jaw crusher top, the dust that the dust producing in material shattering process and material are carried secretly is emptying after dust pelletizing system is filtered by hood, and the material after fragmentation hangs soft curtain to outfeed belt through feed opening chute and second and is transported to next technique.
In the middle of feed opening chute and second hangs soft curtain, dust discharge cover is set, because near producing dirt pits, and be broken air-flow low-pressure area, simultaneously because all arranging, charging aperture and discharging opening hang soft curtain, neither affect the normal work of disintegrating machine, can form again good confined space, so can form good negative pressure in disintegrating machine, thereby reach the object of efficient dust discharge, and dust pelletizing system Air Quantity Required and blast reduce greatly, reduce energy consumption, also do not affected the maintenance of disintegrating machine.
The utlity model has following characteristics:
1, in machine, seal is strong, dust discharge effect is good, can solve the shortcoming of the outer dust discharge of tradition with not enough;
2, the outer dust discharge method of dust discharge Air Quantity Required and blast is compared greatly and is reduced, thereby reduces dust pelletizing system energy consumption;
3, convenient operation personnel facilities for observation ruuning situation, is convenient to equipment maintenance.
In sum, the utility model be a kind of little for jaw crushing function efficient discharge dirt, strong, the required negative pressure of seal and air quantity, be convenient to disintegrating machine maintenance, operation, the inner dust exhaust of jaw crusher simple in structure, dependable performance.
Brief description of the drawings
Fig. 1 is the outside dust discharge method of current traditional jaw crusher and device schematic diagram (arrow is that air-flow moves towards signal).
Fig. 2 is the inner dust discharge method of jaw crusher and the device schematic diagram (arrow is that air-flow moves towards signal) that the utility model provides.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 2, the device of the inner dust discharge method of jaw crusher that what the utility model provided realize, jaw crusher 1 is placed in concrete foundation, above the charging aperture of jaw crusher 1, be provided with movable closed cover plate 2, on movable closed cover plate 2 and between feed belt 4, be provided with the soft curtain 3 of the first suspension, in feed opening chute 6, be provided with the soft curtain 7 of the second suspension, position on feed opening chute 6 between the soft curtain 7 of the second suspension and jaw crusher 1 is provided with hood 8, hood 8 is connected with dust pelletizing system 10 by dirt tracheae 9, feed opening chute 6 belows are outfeed belt 5.
Referring to Fig. 2, the first soft curtain 3 of suspension and second hangs soft curtain 7 and has sealing function, when work, material is delivered in jaw crusher 1 working chamber and is carried out fragmentation by the soft curtain 3 of the first suspension by feed belt 4, operating personnel observe by jaw crusher top movable closed cover plate 2, the dust that the dust producing in material shattering process and material are carried secretly is emptying after dirt tracheae 9 is delivered to dust pelletizing system 10 filtrations by hood 8, and the material after fragmentation hangs soft curtain 7 to outfeed belt 5 through feed opening chute 6 and second and is transported to next technique.
In the middle of feed opening chute 6 and second hangs soft curtain 7, dust discharge cover 8 is set, because near producing dirt pits, and be broken air-flow low-pressure area, simultaneously because all arranging, charging aperture and discharging opening hang soft curtain, neither affect the normal work of disintegrating machine, can form again good confined space, so can form good negative pressure in disintegrating machine, thereby reach the object of efficient dust discharge, and dust pelletizing system Air Quantity Required and blast reduce greatly, reduce energy consumption, also do not affected the maintenance of disintegrating machine.
