Abstract
The utility model belongs to the field of thermal calcium carbide crushing, discloses a jaw crusher capable of adapting to the high-temperature working condition, and aims to solve the problem that a conventional jaw crusher cannot adapt to the high-temperature working condition. The jaw crusher comprises a fixed tooth plate, a side protecting plate, a movable tooth plate, a heat-resistant bearing and graphite lubricating grease, wherein the fixed tooth plate, the side protecting plate and the movable tooth plate adopt segmental structures and high-temperature wear resistance materials. The graphite lubricating grease is refined by inorganic thickening agent thickening ester synthetic oil, ultramicro fine powdered graphite, antioxidant and anticorrosion additives and the like, so that the jaw crusher can stably and continuously work at the temperature of 400 DEG C.
Description
Technical field
The utility model relates to a kind of jaw crusher of worst hot case, belongs to the broken field of thermoelectricity stone.
Background technology
Calcium carbide, calcium carbide, be important basic chemical raw materials, mainly for generation of acetylene gas.Also for organic synthesis, oxycetylene welding etc.The electric furnace reduction method is the unique method of current industrial production calcium carbide.Adopt closed maximization furnace of calcium carbide, coke and lime pulverizing, mix and add closed type calcium carbide furnace by proportioning, and reduction reaction is carried out in the energising heating under 2000-2200 ℃, generates the melting calcium carbide, flows into calcium carbide pot and carry out fragmentation after cooling in stove.Calcium carbide is cooling rear extreme hardness fully, makes fragmentation very difficult.Do not fire when calcium carbide is dry, meet water or moisture and can produce rapidly highly flammable acetylene gas, while reaching certain concentration in air, blasting property disaster.Therefore, disintegrating machine can not adopt water cooling mode to be lowered the temperature to bearing and body.
Current technology prepared by calcium carbide is to be cooled to 400 ℃ of left and right at it to carry out fragmentation.Current common jaw crusher is worked at normal temperatures, and its bearing temperature can not surpass 60 ℃, otherwise light cisco unity malfunction, heavy damage bearing.The high-temperature stable of jaw crusher, the problem of continuous operation have been proposed for this reason.
The utility model content
The technical problems to be solved in the utility model is: a kind of jaw crusher of worst hot case is provided, can 400 ℃ stable, work continuously, solve that current common jaw crusher can not be stablized at 400 ℃, the problem of continuous operation.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows.
The fixed tooth plate of jaw crusher, side guard plate, swing tooth plate have adopted segmental structure and high-temperature and wear-proof, and jaw crusher has adopted high temperature resistant bearing and graphited oil simultaneously, makes jaw crusher can stablize, work continuously at 400 ℃.
Usefulness of the present utility model is as follows.
With common jaw crusher, compare, this programme has taken into full account the particularity of calcium carbide fragmentation, do not adopt the type of cooling to be lowered the temperature to bearing and body, by the meticulous selection of material and the optimal design of structure, solved that common jaw crusher can not be stablized at 400 ℃, the problem of continuous operation, solved the blank of current domestic jaw crusher in the broken field of thermoelectricity stone.
The accompanying drawing explanation
Fig. 1 is the jaw crusher front view.
Fig. 2 is the jaw crusher side view.
Mark in figure: 1 is that fixed tooth plate, 2 is that side guard plate, 3 is that swing tooth plate, 4 is that high temperature resistant bearing, 5 is graphited oil.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model is by the structure shown in accompanying drawing 1,2: fixed tooth plate 1, side guard plate 2, swing tooth plate 3 all adopt segmental structure, all adopt RTCr16 high-temperature wearable cast iron materials.Adopt segmental structure, can dispersed material to the impulsive force of above-mentioned part, fine finishining is carried out in the back side (with the contact-making surface of frame, moving gnathosoma) of above-mentioned part simultaneously, increased the contact area of above-mentioned part, reduce the purpose of impacting thereby reach.Adopt RTCr16 high-temperature wearable cast iron, make above-mentioned part can keep normal mechanical performance at 400 ℃, broken function is stable, continuous operation.
The utility model has also adopted high temperature resistant bearing 4: the high temperature resistant bearing that the plain bearing steel is made after by heat treatment, its serviceability temperature, 300 to 600 ℃ of left and right, can meet the requirement of the broken operating mode of thermoelectricity stone.
The utility model has also adopted graphited oil 5: common high temperature resistant butter viscosity is high; once shut down cooling rear oil sclerosis; lubricating oil can't add; by inorganic thickening agent multiviscosisty synthetic ester lubricant, ultra tiny powdered graphite, the refining graphited oil formed of additive such as anti-oxidant, anticorrosive more than 200 ℃ during high temperature; the carbon residue that stays of base oil slowly volatilizees; graphite can be attached on metal surface and form dry film lubrication; high-temperature resistant can reach 600 ℃, can meet the requirement of the broken operating mode of thermoelectricity stone.
Claims (1)
1. the jaw crusher of a worst hot case, comprise fixed tooth plate, side guard plate, swing tooth plate, high temperature resistant bearing, graphited oil, and wherein fixed tooth plate, side guard plate, swing tooth plate have adopted segmental structure and high-temperature and wear-proof.
