ZXLDM-J mechanical blockage detection device

ZXLDM-J mechanical blockage detection device< Br/>
The blockage detection device adopts a pressure plate door type detection and is installed on the side wall of the chute. When the material causes blockage in the chute, the accumulated material will definitely give pressure to the side wall of the chute, thereby pushing the movable door of this device inward. When the deflection angle of the movable door is greater than the controlled angle, its control switch will act, thereby issuing a warning or shutdown signal. If connected to the control circuit of the vibrator, it can achieve automatic vibration without stopping in case of mild blockage. After troubleshooting the blockage, the movable door will automatically reset< Br/>




Working principle
This device adopts a gate structure, with spring reset, and is installed on the side wall of the chute. When the material causes blockage in the chute, the accumulated material will definitely give pressure to the side wall of the chute, thereby pushing the movable door of this device inward. When the deflection angle of the movable door is greater than the controlled angle, its control switch will act, thereby issuing a warning or shutdown signal. If connected to the control circuit of the vibrator, it can achieve automatic vibration without stopping in case of mild blockage. After troubleshooting the blockage, the movable door will automatically reset< Br/>
Usage conditions

1. Altitude below 2000m

2. Environmental temperature: -35 ℃~+50 ℃

3. Relative humidity: not greater than 95

4. Atmospheric pressure: 80-110Kpa

5. Working position: Installed on the side wall of the chute that is not affected by material impact





Installation and wiring
（1） Installation method:

1. Open 240× at an appropriate position on the side wall of the chute; A 260 rectangular opening, and then a 300mm long baffle is placed on the inner wall of the chute about 100-200mm above the opening to prevent large pieces of material from falling and directly impacting the movable door, causing misoperation. Use randomly selected rubber plates to completely cover and seal the opening< Br/>
1. Use M10× for this device; Tighten the 25 bolts onto the corner fittings< Br/>
（2） Installation essentials and main matters

1. This series of protective devices can be installed in groups of two, on two opposite side walls of the chute that are not affected by material impact, and the height is determined according to user needs. It is generally recommended to install at a height of two-thirds upwards from the bottom of the chute< Br/>
2. This series of product devices can also be used in two groups of four, with one group installed on the side wall of the chute at a relative height of one-third from the bottom, as a light blockage detection. Used to receive signals from the vibration device. When the chute is blocked, the vibration device receives the signal and starts to vibrate; Another set is installed at the bottom two-thirds as a shutdown signal for severe blockage< Br/>
（3） Wiring: A 4-core cable is led out from the protective device

Maintenance and use

After six months of use, this device needs to undergo a maintenance inspection to check for any looseness or detachment of the fastening screws. After tightening, it can be used again. At the same time, apply lubricating oil to the shaft sleeve of the door shaft and remove any accumulated dust< Br/>
