Chute blockage detector XLDS-I, XLDS-II 【 Chute blockage detection device 】 Chute blockage switch product description:

The detector is installed on the side wall of the chute. When a blockage occurs in the chute, the accumulated material will inevitably squeeze the movable door and cause it to shift, activating the travel switch and issuing an alarm or shutdown signal. After troubleshooting, the movable door automatically resets under the action of the weight block< Br/>
Chute blockage detector is mainly used to prevent chute blockage of belt conveyors. The product is suitable for industries such as coal mines, docks, power plants, building materials, chemicals, metallurgy, and grain storage, and is used for conveying bulk materials with belt conveyors< Br/>




XLDS-I Overview: The chute blockage detector is used to detect blockages in coal conveying systems and can provide alarm or shutdown signals. It can also be connected to a vibration motor to troubleshoot blockages< Br/>
Structural characteristics of XLDS-I

1. This detector adopts a side pressure movable door structure. After troubleshooting, the pressure of the weight block automatically resets the valve< Br/>
2. Imported travel switches are used inside the machine, which are sensitive in action and highly reliable< Br/>
3. Small in size, easy to install< Br/>
Cast aluminum shell with anti-corrosion coating

Overloaded microswitch contacts

High sensitivity, with a force of only 0.9Kg to trigger the switch

The imported travel switch is used inside the machine, which is sensitive in action and has high reliability

Chute blockage switch is a common phenomenon in the bulk material conveying system of belt conveyors. Therefore, it is often necessary to have on-site staff handle the blockage of the chute after shutdown, which affects normal production, increases labor intensity of workers, and causes unnecessary economic losses< Br/>
Chute blockage switch can be used in material transportation systems to effectively eliminate blockage, wall sticking, arching and other faults caused by material deliquescence, charged adsorption, crystallization and other reasons, ensuring safe production and improving transportation efficiency. This product is widely used in industries such as metallurgy, power, mining, and chemical engineering< Br/>
Usage conditions of XLDS-I chute blockage switch

1. Altitude below 2000m

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

3. Relative humidity: not more 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

Working principle of XLDS-I chute blockage switch: This device adopts a door type structure, 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 an alarm 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/>
Installation and wiring of XLDS-I chute blockage switch
（1） Installation method:

1. Open 240× at an appropriate position on the side wall of the chute; A 260 rectangular opening is installed, and a baffle with a length of about 300mm is welded to 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/>
