Embodiment Construction

[0051] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0052] The invention discloses a new type of jaw crusher for crushing 400°C high-temperature calcium carbide. The design idea is: apply a heat-insulating coating around the crushing cavity to prevent the heat in the crushing cavity from transferring to the outside of the frame and bearings, and use high-temperature-resistant bearings. , An automatic lubricating system 8 is provided on the drive bearing 12 of the crusher to directly crush calcium carbide at a temperature of about 400°C. The structure of the crusher is shown in the appendix Figure 1-5 . The so-called crusher drive bearing 12 of this machine has 4 disk bearings in total, one disk at the connection between the two ends of the movable jaw body and the eccentric shaft, one disk at the connection between the belt pulley and the eccentric shaft, and one disk at the connection between the flyw...

Abstract

The invention relates to a jaw crusher, in particular to a novel jaw crusher which can crush calcium carbide in a state of the high temperature of 400 DEG C directly in the calcium carbide industry. ZS-1 high-temperature-resistant thermal insulating coatings are applied among a moving jaw protection plate, a moving jaw plate and a moving jaw body, between an edge protection plate and a frame body and between a fixed jaw plate and the frame body respectively, so that a high-temperature thermal insulating layer is formed; a transmission bearing of the crusher adopts 20Cr2Ni4, the hardness of the bearing is HRC 58-60, and the temper temperature is 250 DEG C; the bearing of the crusher comprises an electric lubricant pump, a controller, a distributor and a pipeline connector, and a lubrication system adopts electric single-line progressive lubrication; a rotary speed monitoring protection system is mounted on the crusher; and a temperature sensor which records the changes of the working temperature of a motor is mounted on a driving motor of the crusher. According to the novel jaw crusher, the calcium carbide can be crushed at the temperature of about 400 DEG C, the production cost of PVC (polyvinyl chloride) is reduced, and at the same time, waste caused by import of foreign crushing equipment at a high price is avoided.

Description

technical field [0001] The present invention relates to a jaw crusher, in particular to a calcium carbide (CaC 2 ) with a new jaw crusher. Background technique [0002] The main component of industrial calcium carbide is calcium carbide, the molecular formula is CaC 2 Calcium carbide is mainly used in the production of acetylene, further producing chemical products such as polyvinyl chloride, vinyl acetate, neoprene, trichlorethylene, etc. At the same time, acetylene flames are also widely used in metal welding and cutting. my country's unique calcium carbide method PVC ( Polyvinyl chloride) not only saves a large amount of oil resources for the country, but also provides the premise and guarantee for consumers to use high-quality and cheap PVC (polyvinyl chloride) and other calcium carbide downstream products. [0003] The smelted calcium carbide is in the shape of a cylindrical block. In the process of producing acetylene gas, in order to increase the reaction area of ​​...
