Description
Technical Field
The utility model relates to the technical field of nitrocotton production equipment, in particular to a safety interlocking device for a water-driving centrifugal machine.
Background
The nitrocotton can be packaged only by a water-driving process after undergoing the processes of nitration, boiling and washing. At present, a Huada water-driving centrifugal machine is adopted to drive water of dehydrated nitrocotton, and the water-driving process comprises feeding, dehydrating, washing, discharging and packaging. The rotating speed, the vibration and other equipment permission data of the water driving centrifugal machine are not accessed into the control system, and the equipment permission conditions cannot be monitored in real time. The following safety risks exist in the case of water-driving centrifuges operating at high speeds: 1. the driving centrifuge is in a high-speed rotation process in the dehydration process, the vibration of the driving centrifuge is also increased rapidly, and if the vibration is ultrahigh due to equipment failure, the hidden danger of further safety accidents is caused by failure to take measures in time; 2. according to the process flow, the cotton material layer is scraped off by the scraper only in the low-speed process after the discharging speed of the water-driving centrifugal machine is stable. The condition of scraper misoperation exists in the high-speed rotation process of the water-driving centrifugal machine.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a safety interlocking device for a water-driving centrifugal machine, which can control the operation of the centrifugal machine in real time and ensure the safety of the centrifugal machine.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the safety interlocking device for the water-driving centrifugal machine comprises a control system, the centrifugal machine and a main motor for driving the centrifugal machine to run, wherein the main motor is provided with a controller electrically connected with the main motor, and the safety interlocking device also comprises a vibration sensor, and the vibration sensor is arranged on a shell of the centrifugal machine; the centrifugal machine also comprises a position sensor, wherein the position sensor is arranged on a scraper of the centrifugal machine, and the vibration sensor, the position sensor and the controller are all electrically connected with a control system.
Further, the method comprises the following steps: the position sensor is a proximity switch.
Further, the method comprises the following steps: the rotating speed sensor is arranged on the output shaft of the main motor; the rotating speed sensor is electrically connected with the control system.
The utility model has the beneficial effects that: because install vibration sensor, position sensor, revolution speed transducer on driving water centrifuge, be connected above sensor and control system electricity, sensor signal spreads into current control system into, and the staff of being convenient for carries out real time monitoring to the running state of equipment to utilize control system to realize driving water centrifuge safety real time control, reduce safe risk.

FIG. 1 is a schematic structural view of the present invention;
labeled as: the device comprises a main motor 1, a vibration sensor 2, a position sensor 3, a scraper 4 and a rotating speed sensor 5.
Detailed Description
The utility model is further described with reference to the following figures and detailed description.
The safety interlocking device for the water-driving centrifugal machine comprises a control system, the centrifugal machine and a main motor 1 for driving the centrifugal machine to run, wherein the main motor 1 is provided with a controller electrically connected with the main motor 1, the safety interlocking device also comprises a vibration sensor 2, and the vibration sensor 2 is arranged on a shell of the centrifugal machine; the vibration sensor 2 can be connected with the control system through a two-wire system 4-20mA signal, when the vibration value of the centrifuge is larger than 75mm/s, the control system sends a shutdown signal to the controller, and the controller controls the main motor 1 of the centrifuge to stop running; the scraper position sensor 3 is arranged on a scraper 4 of the centrifuge, so that the position of the scraper 4 can be detected conveniently; the vibration sensor 2, the position sensor 3 and the controller are all electrically connected with a control system. More specifically, the control system is a DCS system, and the controller is a PLC controller.
Specifically, the position sensor 3 is a proximity switch, and a switching value signal of the proximity switch is connected to the DCS system.
The device comprises a main motor 1, a rotating speed sensor 5, a speed sensor and a controller, wherein the rotating speed sensor 5 is arranged on an output shaft of the main motor 1; and the rotating speed sensor 5 is electrically connected with the DCS system. Under the condition that the rotating speed of the main motor 1 of the centrifuge is greater than 80r/min, if the position signal of the scraper 4 is abnormal, the DCS controls the PLC to stop the operation of the main motor 1 of the centrifuge.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
