Abstract
Description
Technical Field
[0001] The utility model relates to a positive electrode material roasting device, in particular to a sagger conveying position misdetection preventing device. Background Art
[0002] In the process of positive electrode material roasting, kilns are usually used for roasting, and saggers are one of the important auxiliary equipment for roasting positive electrode materials. The kilns used for sintering positive electrode materials are mostly track kilns. During sintering, a single sagger is placed on the conveyor track. Through a certain procedure, the rolling speed of the conveyor track is set, the temperature of the kiln is set, and the positive electrode material is sintered continuously.
[0003] During the operation of the sagger on the outer line of the kiln, the sagger transmission at the loading station and the flipping and unloading station has high requirements for the positioning of the sagger. A slight deviation of the sagger position will affect its normal operation. When the sagger needs to be accurately positioned, its start and stop positions are usually controlled by a photoelectric sensor switch. However, due to the high dust content at the construction site, the transmitter or receiver of the photoelectric sensor switch will be blocked, making the photoelectric sensor ineffective, which will lead to inaccurate loading and flipping positions or failure to detect the sagger, resulting in damage to the sagger, missing loading or missing unloading, further causing downtime or reduced production, and increased production costs. Summary of the invention
[0004] Purpose of the utility model: The purpose of the utility model is to provide a device for preventing misdetection of sagger conveying position, which can accurately position the sagger and reduce production costs.
[0005] Technical solution: The device for preventing misdetection of the sagger conveying position described in the utility model comprises a track for conveying the sagger, a wire body installed on the track, a driving device for driving the movement of the sagger, and a controller for controlling the movement of the sagger. A monitoring device for monitoring the position of the sagger is provided on the side of the track, and the monitoring device is an ultrasonic sensor.
[0006] Preferably, the ultrasonic sensor is mounted on a bracket.
[0007] Preferably, a limit switch for assisting in monitoring the position of the sagger is installed on the track.
[0008] Preferably, the limit switch is installed on the telescopic rod.
[0009] Preferably, the telescopic rod is installed on a track to control the up and down movement of the limit switch, thereby limiting the movement of the sagger.
[0010] Preferably, the line body is a roller or a chain.
[0011] Preferably, the material of the sagger is one or more of aluminosilicate, high-aluminum, magnesia, and silicon carbide.
[0012] Preferably, the controller is a programmable logic controller.
[0013] Preferably, the material of the sagger is one or more of aluminosilicate, high-aluminum, magnesia, and silicon carbide.
[0014] Beneficial effects: Compared with the prior art, the present utility model has the following remarkable advantages: (1) The ultrasonic sensor is used to replace the opposed photoelectric induction switch, avoiding the influence of dust on the opposed photoelectric induction switch, preventing the misdetection of the sagger position, and ensuring the stable operation of the system; (2) The sagger is accurately positioned to avoid the situations of sagger damage, missing loading, and missing discharging; (3) The ultrasonic sensor and the limit switch are arranged to double-monitor the position of the sagger to ensure the normal operation during the sagger transmission process. Description of the Drawings
[0015] Figure 1 It is a schematic diagram of the overall appearance of the present utility model. Detailed Embodiment
[0016] The technical solution of the present utility model will be further described below in conjunction with the embodiments.
[0017] As shown in the figure, the anti-misdetection device for the sagger conveying position of the present utility model includes a track 1 for conveying the sagger, a wire body 2 installed on the track 1, a driving device for driving the sagger 3 to move, a controller for controlling the movement of the sagger 3, and a monitoring device for monitoring the position of the sagger 3 arranged beside the track 1. The monitoring device is an ultrasonic sensor 4 installed on a bracket 6.
[0018] In this embodiment, the wire body 2 is a roller.
[0019] A limit switch 5 for assisting in monitoring the position of the sagger 3 is installed at the position on the track 1 where the sagger 3 needs to stop.
[0020] The limit switch 5 is installed on a telescopic rod 7.
[0021] The telescopic rod 7 is installed on the track 1 and is used to control the up and down movement of the limit switch 5, thereby restricting the movement of the sagger 3.
[0022] When the limit switch 5 is in the upward extended position, its highest point is higher than the lowest point of the sagger; when the limit switch 5 is in the downward retracted position, its highest point is lower than the lowest point of the sagger.
[0023] The material of the sagger 3 is one or more of aluminosilicate, high-aluminum, magnesia, and silicon carbide.
[0024] The controller is a programmable logic controller (i.e., PLC).
[0025] The working principle of the anti-misdetection device for the conveying position of the sagger described in the present utility model is as follows: During the operation of the sagger on the outer line of the kiln, the conveyance of the sagger is achieved through the track and the roller. When the sagger runs to the position where it needs to stop, the ultrasonic sensor will receive the corresponding signal, and this signal is transmitted to the PLC. The PLC then controls the roller to pause rolling, thereby making the sagger stop moving at the position where it needs to stop. At the same time, the corresponding sagger will also trigger the limit switch, causing the telescopic rod to retract downward, and the restriction of the limit switch is then released. This signal is also transmitted to the PLC to make the roller pause rolling, so as to achieve double monitoring of the sagger position. After the sagger stops moving, the operation of loading the sagger or flipping and discharging can be completed at this station. After this operation is completed, the PLC will receive the signal that the operation is completed and control the roller to continue rolling, and the sagger will continue to move forward. When the sagger leaves the detection range of the ultrasonic sensor, the PLC emits a signal, and the telescopic rod extends upward, waiting to convey the next sagger.
[0026] If the ultrasonic sensor fails or is affected by the material of the sagger itself, resulting in the inability to respond to the sagger position, the existence of the limit switch can ensure that the sagger stops at a specific position to complete the operation of loading the sagger or flipping and discharging. The settings of the ultrasonic sensor and the limit switch can double monitor the position of the sagger to ensure the normal operation during the sagger transmission process.
