Door collision preventing device of viscous fiber cake drying kiln

Abstract

The invention provides a door collision preventing device of a viscous fiber cake drying kiln. A drying kiln for drying viscous fiber cakes is provided with electric propelling devices for propelling drying carts on a guide rail at equal intervals in a sealing door inlet position of a kiln body; and the electric propelling devices are that a transmission shaft of a propelling motor is connected with equidistant propellers, and are communicated with an electric starter connected with vehicle dispatch detecting limiters through power supply wires. When the door collision preventing device is used, the existence of the carts is detected through the limiter in the last parking place in the outlet of the drying kiln; when the existence of the carts is detected, the power supply starter cannot be started; when no cart is detected, the power supply starter can be started to control selective starting of the propelling devices, so that the problems of equipment damage and influence on safety due to collision of an exit sealing door through direct cart entering caused by forgetting of operators in a traditional operation are effectively solved; and the door collision preventing device has prominent characteristics of scientific and reasonable control, economy and practicability and high reliability.

Description

technical field [0001] The invention relates to a device used in chemical fiber production, in particular to an anti-collision door device for a viscose fiber silk cake drying kiln. Background technique [0002] In the production of viscose filament yarn, after being cleaned by pressure washing process, the formed yarn cake needs to be dried in the drying process. In the drying process, the silk cake is loaded into the drying trolley in multiple layers, and pushed into the drying kiln by the equidistant propeller for drying treatment. The equidistant propeller is driven by the motor, and the distance of each propulsion is just one small parking space. The drying kiln is about 50 meters long, and it can dry multiple shredded cakes step by step at the same time. In this operation procedure, the operator pushes the last trolley of the drying kiln out from the exit for each operation to free up a parking space, and then starts the propeller at the entrance to push all the troll...

AI Technical Summary

Problems solved by technology

In actual operation, due to the distance between the entrance and exit is nearly 50 meters, occasionally the operator forgets to get out of the car and directly enters the car, resulting in the phenomenon that the closed door at the exit of the drying kiln is knocked down

In this operation, although the propeller is equipped with an equidistant limit, the actual operation must strictly follow the steps of getting out of the car first and then entering the car. It is inevitable that the operator will make mistakes when going in and out of the car every day. Avoid it completely, that is, it will cause damage to the equipment, and it will also leave hidden dangers to safety
