The hydraulic rotary cone crusher is simple in structure; due to the adoption of a double-seal assembly formed by two seals, the sealing effect is preferable; the service life is long, the transmission efficiency is effectively improved, and the service is reliable.
Description
Technical field
The utility model relates to disintegrating apparatus, relates in particular to a kind of hydraulic gyre cone crusher black box that is applied to the industrial circles such as metallurgy, chemical industry, building materials, electric power, traffic, various materials is carried out to coarse crushing processing.
Background technology
Hydraulic rotary crusher is widely used in the industries such as metallurgy, building materials, chemical industry and water power, it is one of capital equipment of coarse crushing ore or rock, its primary structure comprises that motor, power transmission shaft, excentric sleeve, main shaft, upper frame, middle support body, lower frame, mantle portion and dust cover etc., main shaft lower end are inserted in excentric sleeve inside, main shaft upper end is mantle portion fixedly, between mantle portion and upper frame, middle support body, forms crusher chamber; Motor, power transmission shaft, gear form transmission component power are passed to excentric sleeve, thereby eccentric shaft drives main shaft to drive mantle portion to do swing campaign, bulk materials enters crusher chamber, along with the motion of mantle portion, material between the crushing wall of mantle portion and support body, be constantly squeezed, shear and bending after be broken rapidly.Although this equipment has the features such as the ratio of reduction is large, production capacity is high, product granularity is even, but also there is certain deficiency, it is mainly the poor performance of dust sealing, the design of existing hydraulic rotary crusher dust sealing is, what at crusher chamber and extraneous dust seal, lean on is middle ring is set on broken head and with rubber tube, does filler within it, add dust cover, in order to intercept the transmission component that is immersed in of breeze.This sealing effectiveness is extremely undesirable, does not reach the object of dust seal at all.During maintenance, can find in machine oil, with sediments such as a large amount of mineral powders and metal fillings, directly affects engine oil quality, and at this moment the sediment in fuel tank accounts for 5--10%.Due to the oily extreme difference in fuel tank, each driving member of heavy wear and copper part, cause reduce the service life of mechanical transmission component, increased equipment operation failure rate, also just makes production cost greatly improve.
Summary of the invention
The purpose of this utility model is to provide a kind of simple and reasonable, good sealing effect, can extension device the hydraulic gyre cone crusher with black box in service life.
The purpose of this utility model realizes in the following manner.
According to the hydraulic gyre cone crusher with black box of the present utility model, comprise motor, power transmission shaft, excentric sleeve, main shaft, conical gear, upper frame, middle support body, lower frame, mantle, middle ring and hydraulic system, lower frame is arranged on the bottom of mantle, the lower end of main shaft is inserted in excentric sleeve inside, the upper end of main shaft is fixed on the top of mantle, mantle upper end is provided with hydraulic system, on middle ring, be provided with seal, on excentric sleeve top, be provided with dust cover, mantle and upper frame, between middle support body, form crusher chamber, lower frame is arranged on the bottom of mantle, form transmission system annular seal space with ground, it is characterized in that described seal is by the lower seal collar of high abrasion EU, the upper sleeve gasket ring middle sealing ring middle with being arranged on upper sleeve gasket ring and the lower seal collar forms, outside at described lower frame is provided with air feed system, on described lower frame, have for airduct import, described air feed system is by air compressor machine, the air accumulator being connected with air compressor machine, gas storage is tank connected therewith forms for airduct and the magnetic valve being arranged on on airduct, described passes for airduct import and inserts in transmission system annular seal space for airduct.
The utility model has the advantages that:
1) of the present utility modelly adopted that above-mentioned high abrasion EU is three-layer sealed has formed first sealing, three sealing ring assembly precisions are very high, and wearability is extremely strong, has effectively intercepted entering of ore dust;
2) the utility model is provided with air feed system and has formed second sealing in the annular seal space of transmission system, and this sealing is to adopt by pipeline to introduce wind regime from outside, enters into the closed circuit malleation wind-force of formation in transmission system annular seal space.This air inlet pipeline adopts and filters air source apparatus, guarantees the gaseous mass of air intake, has further guaranteed that transmission system do not invaded by dust, and air inlet pipeline of the present utility model adopts magnetic valve automatically to control.
The utility model is simple in structure, and two seals forms dual-seal component, good sealing effect, and long service life, has improved transmission efficiency, reliable operation effectively.
