Abstract
The invention discloses an internal dust exhausting method of a jaw crusher. A feed opening of the jaw crusher is sealed by a soft curtain. A movable cover plate is arranged on the upper part of the jaw crusher. A discharge opening chute of the jaw crusher is sealed by a soft curtain. A dust collection point is arranged at a crushing dust production point of the jaw crusher, and is a dust exhausting cover between the discharge opening chute and the soft curtain, and the dust exhausting cover is connected with a dust removal system through a dust-gas pipe. According to the dust exhausting method, dust can be efficiently exhausted from the jaw crusher, high sealing performance is ensured, low negative pressure and a small volume of air are required, and the crusher is convenient to maintain and operate. A device for implementing the internal dust exhausting method of the jaw crusher is simple in structure and reliable in performance.
Description
Technical field
The present invention relates to a kind of inner dust discharge method of jaw crusher, the invention still further relates to a kind of device of realizing the method.
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
First technical problem to be solved by this invention is to provide a kind of, dust discharge method of being convenient to disintegrating machine maintenance, operation little for jaw crushing function efficient discharge dirt, strong, the required negative pressure of seal and air quantity.
Second technical problem to be solved by this invention is to provide a kind of device of realizing the inner dust discharge method of this jaw crusher.
In order to solve above-mentioned first problem, the inner dust discharge method of jaw crusher provided by the invention, jaw crushing machine inlet capable adopts soft curtain airtight, described jaw crusher top adopts removable cover, in described jaw crusher feed opening chute, adopt soft curtain airtight, dust sucting point is located at the fragmentation of jaw crusher and produces dirt pits.
Described dust sucting point is, between described feed opening chute and soft curtain, dust discharge cover is set, and described dust discharge cover is connected by dirt tracheae with dust pelletizing system.
In order to solve above-mentioned second technical problem, the device of realizing the inner dust discharge method of jaw crusher provided by the invention, 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 discharge method of jaw crusher and the device 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 present invention 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 present invention is a kind of, dust discharge method of being convenient to disintegrating machine maintenance, operation little for jaw crushing function efficient discharge dirt, strong, the required negative pressure of seal and air quantity.The apparatus structure of realizing the inner dust discharge method of this jaw crusher is simple, dependable performance.
