High-yield asphalt coating device for high-voltage cable production

Abstract

The invention discloses a high-yield asphalt coating device for high-voltage cable production, and the device comprises a processing box body, a partition plate and an ash removal mechanism; four supporting legs are welded to the bottom of the processing box body in a rectangular array mode, corresponding through holes are formed in the two symmetrical side walls of the processing box body, four first transmission motors are installed on the outer wall of one side of the machining box side by side, two partition plates are longitudinally and fixedly connected to an inner cavity of the machining box in an inserted mode, and the two partition plates sequentially divide the machining box into an ash removal cavity, a coating cavity and a drying cavity from left to right; and an ash removal mechanism is arranged in the ash removal cavity and comprises a water storage tank, a linear vibration motor and a connecting frame. According to the high-yield asphalt coating device for high-voltage cable production, dust and impurities on the surface of a high-voltage cable are removed before coating so as to ensure that the adhesion effect of asphalt in the subsequent coating process is better, the yield is higher, and the high-voltage cable can be efficiently dried so as to ensure the efficiency of the production process.

Description

technical field [0001] The invention belongs to the technical field of high-voltage cable processing, and in particular relates to an asphalt coating device for high-voltage cable production with high yield rate. Background technique [0002] High-voltage cable is a kind of power cable. It is a power cable used to transmit 1kv-1000kv. It is mostly used in power transmission and distribution. The components of high-voltage cables from the inside to the outside include: conductors, insulation, inner In order to ensure the performance of high-voltage cables, sheaths, fillers, and external insulation, it is necessary to strictly control each production link of high-voltage cables. [0003] For example, the Chinese invention application number is CN201210325458.5, which is an adjustable scraping type high-voltage cable asphalt coating device, including a nozzle for spraying asphalt and a scraping belt for scraping the surface of the cable after asphalt spraying, and it also inclu...

[0003] For example, the Chinese invention application number is CN201210325458.5, which is an adjustable scraping type high-voltage cable asphalt coating device, including a nozzle for spraying asphalt and a scraping belt for scraping the surface of the cable after asphalt spraying, and it also includes frequency conversion Motor, frequency converter, PLC controller and potentiometer, the potentiometer gives the analog quantity to the flow of asphalt, the signal of the potentiometer is transmitted to the PLC controller, and the digital operation of the PLC controller is transmitted to the frequency converter, and the frequency converter sets The low-speed vector controls the action of the variable frequency motor, and the speed of the variable frequency motor controls the flow rate of the asphalt pump, thereby controlling the nozzle to spray at an appropriate flow rate. This invention uses an electrical automation closed-loop to effectively control the flow rate of asphalt, which solves the problem of uneven spraying of asphalt, making The high-voltage cables are stably coated during the production process, but the existing equipment does not remove the dust and impurities on the surface of the high-voltage cables before coating, resulting in poor asphalt adhesion in the subsequent coating process, so the yield rate is not high enough, and The problem of not being able to efficiently dry high-voltage cables to ensure the efficiency of the production process
