Spark detector for conveying cotton

Abstract

The invention relates to a spark detection device and particularly discloses a spark detector for conveying cotton. The spark detector for conveying the cotton comprises a spark detection part and an executing mechanism which are mounted on a cotton conveying pipeline in series, and is characterized in that the executing mechanism comprises an engaging pipe communicated with the cotton conveying pipeline; the bottom face of the engaging pipe is a turning plate which is controlled by an external connection rod; an output channel is formed in the lower part of the engaging pipe; the connection rod is provided with a pneumatic device; an air pipe connected with an air pump is arranged at the top of the pneumatic device; and an inductor is arranged on the air pipe. The spark detector for conveying the cotton has the advantages of simple structure, convenience for utilization, reasonable design, flexibility in application, rapid action response, low fault rate and stability in operation; and the production efficiency is easily improved and the maintenance cost is reduced, and the spark detector for conveying the cotton is suitable for wide popularization and application.

Description

(1) Technical field [0001] The invention relates to a Mars detection device, in particular to an activity detector for cotton transportation. (2) Background technology [0002] In textile enterprises, cotton and other textile fibers are easily activated due to mechanical rotation during the process of opening, removing impurities, and absorbing cotton. The cotton outlet of one machine is sent to the cotton box of another machine, and it is easy to burn during this process and cause a fire. In order to prevent the occurrence of fire, a spark detector must be installed on the cotton pipeline. This device can detect the existence of sparks in time, and discharge the cotton and other textile fibers with sparks into the fire extinguishing box to extinguish the sparks. [0003] The Mars detection device currently used on the cotton pipeline is composed of a Mars detection component, a control box and an actuator. The Mars detection component and the actuator are connected in seri...

AI Technical Summary

Problems solved by technology

[0003] The Mars detection device currently used on the cotton pipeline is composed of a Mars detection component, a control box and an actuator. The Mars detection component and the actuator are connected in series on the cotton pipeline. The final weak voltage signal is amplified by the voltage amplifier and then sent to the control box, and finally the valve in the actuator is controlled by the control box, so the action time of the actuator is synchronized with the action time of the control box, so it is necessary to control the spark. The installation distance between the detection component and the actuator should be kept as small as possible, generally within 3 meters. Even so, it is difficult to discharge the cotton and other textile fibers with Mars into the Fire extinguishing box, because in principle, the action time of the actuator should be later than that of the control box, and the opening and closing response of the actuator is determined by the speed of the mechanical action
