Abstract
The utility model relates to the technical field of belt conveyors, in particular to a secondary protection device for preventing material returning of a belt conveyor. The automatic feeding device comprises a lengthened carrier roller, wherein two ends of the upper part of the lengthened carrier roller are respectively welded with a contact plate, the lower part of the lengthened carrier roller is welded with a fixed belt clamping plate, the fixed belt clamping plate is entrained with a belt baffle for material touch, the lengthened carrier roller is fixed on a belt rack of a belt machine head, and an electric travel switch is arranged at the front end of the lengthened carrier roller. The device utilizes the lengthened carrier roller and the electric travel switch to manufacture a trigger device, and realizes protection shutdown by touching the device through the materials on the return belt. The device and the belt conveyor blocking switch and the anti-tearing device form secondary protection, thereby avoiding belt accidents and ensuring the stability of a material conveying system. Simple and practical structure, safety and reliability, and easy processing and manufacturing.
Description
Technical Field
The utility model relates to the technical field of belt conveyors, in particular to a secondary protection device for preventing material returning of a belt conveyor.
Background
In the prior art, when the belt conveyor is blocked, the situation that the material blocking device does not act sometimes occurs, so that the belt conveyor does not stop running, the belt conveyor head is caused to emit materials, and the belt is broken. Because the feeding belt is unattended, the equipment runs in a single line, a standby system is not available, and once belt faults occur, the conveying of finished products such as sinter, pellet, coke and the like is interrupted, the finished products cannot be timely conveyed to a blast furnace, and the stable and smooth production of the blast furnace is directly influenced.
Disclosure of Invention
The utility model aims to provide the secondary protection device for preventing the belt conveyor from returning materials, which is simple and practical in structure, safe and reliable and aims to overcome the defects.
The technical scheme of the utility model is as follows: the secondary protection device for preventing the material returning of the belt conveyor is characterized by comprising an extension carrier roller, wherein two contact plates are respectively welded at two ends of the upper part of the extension carrier roller, a fixed belt clamping plate is welded at the lower part of the extension carrier roller, a belt baffle for material touching is entrained in the fixed belt clamping plate, the extension carrier roller is fixed on a belt rack of a belt machine head, and an electric travel switch is arranged at the front end of the extension carrier roller.
In the above scheme, the method further comprises:
the lower edge of the belt baffle is 10-25mm away from the return belt.
The utility model has the advantages that: 1. the device utilizes the lengthened carrier roller and the electric travel switch to manufacture a trigger device, and realizes protection shutdown by touching the device through the materials on the return belt. 2. The device and the belt conveyor blocking switch and the anti-tearing device form secondary protection, thereby avoiding belt accidents and ensuring the stability of a material conveying system. 3. Simple and practical structure, safety and reliability, and easy processing and manufacturing.
Embodiments of the present utility model will be described in further detail below with reference to the accompanying drawings.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model.
Fig. 2 is a schematic view of the installation site of the present utility model.
Detailed Description
Referring to fig. 1 and 2, the names of the parts are as follows: the device comprises a lengthened carrier roller 1, a contact plate 2, a fixed belt clamping plate 3, a belt baffle 4, an electric travel switch 5, a material 6, a standby position 7 of the device, an action position 8 of the device and a belt 9.
Referring to fig. 1 and 2, the secondary protection device for preventing the material from returning of the belt conveyor comprises an elongated carrier roller 1, two contact plates 2 are respectively welded at two ends of the upper part of the elongated carrier roller 1, a fixed belt clamping plate 3 is welded at the lower part of the elongated carrier roller, a belt baffle 4 for material touching is entrained in the fixed belt clamping plate 3, and the lower edge of the belt baffle 4 is 10-25mm away from a return belt. The lengthened carrier roller 1 is fixed on a belt frame of a belt machine head, and an electric travel switch 5 is arranged at the front end of the lengthened carrier roller 1. When the belt blanking plug does not act, the material can be piled up to return the journey belt, touches belt baffle 4, and this device can rotate to the action position by standby position, touches electric travel switch 5, realizes the interlocking and shut down, avoids the belt accident to take place, ensures the stability of blast furnace material loading.
The device utilizes the lengthened carrier roller 1 and the electric travel switch 5 to manufacture a trigger device, and realizes the protection shutdown by touching the device through the materials on the return belt.
The above description is only of specific embodiments of the present utility model, and the various illustrations do not limit the essential content of the present utility model.
