Description
Technical field
The utility model relates to a kind of jaw crusher, particularly relates to a kind of calcium carbide (CaC under directly broken 400 ℃ of conditions of high temperature that can carry out in calcium carbide industry
2) use new type jaw crusher.
Background technology
The main component of industry calcium carbide is calcium carbide, and molecular formula is CaC
2calcium carbide is mainly for the production of acetylene, further produce the chemical products such as polyvinyl chloride, vinyl acetate, neoprene, trichloro-ethylene, acetylene torch is also widely used in the welding and cutting of metal simultaneously, the calcium carbide process PVC that China shows unique characteristics (polyvinyl chloride) is not only for country has saved bulk petroleum resource, also for consumers in general use inexpensive PVC(polyvinyl chloride) etc. calcium carbide downstream product precondition and guarantee is provided.
The cylindrical bulk of calcium carbide after melting, in the process of acetylene gas processed, for increasing the response area of calcium carbide, can fully react calcium carbide, improves the reaction rate of calcium carbide, need carry out fragmentation to the calcium carbide after melting, the method for current domestic broken calcium carbide:
1, under normal temperature (20 ℃) state, calcium carbide is broken;
The method is very strict to calcium carbide temperature requirement, utilizes common jaw crusher just can complete, but in actual production the disappearance of tool below existing:
(1) environmental pollution, due to the disintegrating machine that domestic design is manufactured at present, all can not be directly broken to high temperature calcium carbide, calcium carbide cooling velocity is relatively slow, calcium carbide manufacturer is in order to enhance productivity, therefore be sold to each PVC(polyvinyl chloride) calcium carbide of manufacturing enterprise, all without broken bulk stone roller shape calcium carbide, PVC(polyvinyl chloride) manufacturing enterprise after buying needs it to carry out fragmentation, after reaching release mesh, screening could utilize, and calcium carbide is in fragmentation, in screening and transportation, understand a large amount of dust that produce and give out pernicious gas, have a strong impact on the environment of plant area of PVC manufacturing enterprise, and the environment of plant area's periphery.
(2) reduce calcium carbide utilization rate; Coarse crushed calcium-carbide is being transported to PVC(polyvinyl chloride) in manufacturing enterprise's process, because calcium carbide volume ratio is larger, poorly sealed close, calcium carbide very easily contacts weathering with airborne steam, and then reduce the effective rate of utilization of calcium carbide.
2, under high temperature (400 ℃ of left and right) state, calcium carbide is broken;
The method is very strict to the requirement of disintegrating machine:
First the disintegrating machine of domestic production cannot be realized directly fragmentation of calcium carbide under high temperature (400 ℃ of left and right) state, mainly has following reason:

(2) support body intensity
The support body of jaw crusher is welded by ordinary carbon steel plate (Q235-A), and when the calcium carbide of long-time broken 400 ℃ of left and right, it is even destroyed that support body produces distortion under the effect of high-temperature baking and intense impact power.
(3) harmfulness of support body heat by conduction
Common jaw crusher is not taked any provision for thermal insulation, when the high temperature calcium carbide of broken 400 ℃ of left and right, the heat of calcium carbide can conduct along crusher chamber outside Rack Body, causes the outer excess Temperature of Rack Body, workman cannot carry out normal operation and maintenance to disintegrating machine, has serious potential safety hazard;
3. the external high temperature calcium carbide crusher of import, carries out fragmentation, also Shortcomings although can realize calcium carbide 400 ℃ of left and right:
(1) expensive; External high temperature calcium carbide crusher price is more expensive, and a high temperature calcium carbide crusher price is about 8,000,000 left and right, and high temperature (400 ℃ of left and right) the calcium carbide crusher price of Er Hui power company development is its 1/8 left and right only.
(2) maintenance difficult; Buy external this high temperature calcium carbide crusher, once disintegrating machine breaks down, need producer to send professional and technical personnel to process, the cycle is long after sale, the delivery cycle of simultaneously corresponding standby redundancy reaches 4-6 month and expensive, seriously restricts and affect the normal production of calcium carbide manufacturing enterprise.
