Description

Technical Field

[0001] The utility model relates to the technical field of roller kiln discharging, in particular to a roller kiln discharging device. Background Art

[0002] A roller kiln is a rotating drum type equipment, usually used for heat treatment, sintering, roasting or drying under high temperature conditions. A roller kiln is usually composed of a long and inclined rotating drum. Different combustion and heating areas can be set up in sections according to process requirements to achieve heating, sintering or drying of the materials to be processed. The discharging device of the roller kiln is a device used to smoothly remove or discharge the materials processed or produced in the kiln from the kiln body;

[0003] The existing discharging device of the roller kiln usually uses a number of conveying rollers to convey the materials or the bearing structure carrying the materials to achieve discharging. When the materials are processed through the roller kiln, due to the uneven distribution of the bearing gravity of the materials or the bearing structures carrying the materials, the conveying rollers are smooth in the conveying process, which may cause the materials or the bearing structures carrying the materials to fall off from the conveying rollers, causing the materials to be damaged or fall, thereby reducing the production quality of the materials. In addition, the materials have a high temperature during the discharging process and need to be naturally cooled before they can be manually recovered, which reduces the processing efficiency. Therefore, we propose a discharging device for the roller kiln. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model cooperates with each other by arranging a second motor, a threaded rod, a limit plate, a collar, a ball and a laser rangefinder. During discharging, the second motor is controlled by a matching control panel to drive the threaded rod to rotate forward and backward according to the size and width of the material or the carrying box carrying the material. The threaded rod drives the limit plates to slide toward or relative to each other under the limit of the conveying roller through the relative threads opened at both ends of the surface, thereby adjusting the distance between the limit plates, so that during the discharging process, the material or the carrying box carrying the material is limited by the limit plates, thereby avoiding the material or the carrying box from deviating during the discharging process, preventing it from falling off, ensuring the stability of the discharging, and during the adjustment, the distance between the limit plates can be detected in real time by the laser rangefinder during the adjustment, so that it can be accurately adjusted during the adjustment, and different materials can be used for discharging within the moving range. During the discharging process, the nested ball on the inner wall surface of the limit plate can reduce the friction coefficient on the inner side of the limit plate, so that when the material collides with the limit plate, the moving direction of the material can be changed by the ball, preventing the material from being damaged, and further improving the discharging effect.

[0013] 2. The utility model cooperates with the air cooling hood, the blower, the ventilation duct, the air outlet and the air guide duct. When discharging, when the material moves on the conveying roller, the blower blows air to convey the external cold air into the ventilation duct, and blows it to the material being conveyed with the help of the air outlet, so that the material can be cooled quickly, effectively saving time and improving processing efficiency. While blowing air, the cold air is guided into the drive box through the ventilation duct to cool the transmission gear and the drive gear in the inner cavity of the drive box, so as to avoid the gear temperature being too high and affecting the transmission effect or being damaged, effectively extending the service life, ensuring the stability of the transmission during discharging, and then effectively driving the conveying roller to rotate and drive the material to discharge.
