An alarm device for broken rollers used in orbital kilns

Abstract

The invention discloses a roller bar breaking alarming device for a track kiln. The roller bar breaking alarming device comprises laser shielding pieces, a laser range finder and an alarm system. The laser shielding pieces are correspondingly assembled with roller bars in a one-to-one manner and are kept to coaxially rotate. Each laser shielding piece is provided with a laser shielding part. The laser shielding parts of all the laser shielding pieces are kept to synchronously rotate. When the roller bars normally run in a non-bar-breaking state, the laser shielding part kept closest to the laser range finder conducts periodical intermittent shielding on laser beams. When the roller bars abnormally run in a bar breaking state, the broken roller bars stop rotating and are up warped, the shielding state is kept for the laser beams all the time, and the alarm system calculates the roller bar positions of the broken roller bars according to the distance measured by the laser range finder and sends alarm signals. The roller bar breaking alarming device is simple and exquisite in structural design, the bar breaking detection performance is reliable, positioning of the broken roller bars is accurate, and a real-time monitoring and alarming function can be achieved.

Description

technical field [0001] The invention relates to the technical field of orbital kilns, in particular to a roller broken alarm device for an orbital kiln. Background technique [0002] The roller kiln belongs to the tunnel type kiln. The roller table of the roller table kiln is composed of roller bars arranged in parallel and crossing the section of the kiln working channel. The products can be placed directly on the roller table or on the backing plate. The roller is rotated by the transmission system, so that the product is transported into the kiln with the rotation of the roller, and the firing process is completed in the kiln. There are more and more roller kilns in the lithium battery industry. Due to the long firing cycle of lithium battery materials, the length of the kiln is relatively short, generally about 40 meters. The conveying speed of the silicon carbide rollers used is relatively slow, and the rotation of the rollers It is also very slow. It is difficult for ...

Problems solved by technology

In this structure, the cooperation between the detection part and the follower corresponding to the roller rod one by one is used to judge whether the roller rod is broken. Although real-time detection can be realized, the design is complicated, and the detection components and sensors are used in many applications, and the probability of damage is high. , complex maintenance and management
