Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor equipment, in particular to a belt leakage detection device. Background Art

[0002] At present, in the production process of wet smelting enterprises such as alumina, raw materials are transported by belt conveyors. In the process of using belts to transport materials, due to changes in factors such as material size and humidity, it is sometimes easy for materials to spill at specific locations such as the feed port or belt turns. If the inspection personnel cannot find it in time, a large amount of materials will continue to spill, increasing the workload of the cleaning personnel. Therefore, it is necessary to conduct leakage detection on specific locations where these transport belts are prone to spillage, so as to promptly warn the staff to recycle these spilled raw materials, avoid continuous spillage of materials, affect the on-site environment, and cause a large amount of material waste. In response to the above needs, the utility model provides a belt leakage detection device. Utility Model Content

The specific number of the guide rods 2, the springs 22 and the adjusting nuts 23 can be determined according to the size of the actual object. In this embodiment, the number of the three can be set to 2; the top of each guide rod 21 is fixedly connected to the bottom of the receiving hopper 1; the bottom of each guide rod 21 is connected to the top of the base 4 in a lifting and sliding manner, and the bottom of each guide rod 21 passes through the top of the base 4 and is threadedly connected to an adjusting nut 23; each spring 22 is sleeved in a On the guide rod 21, the top of each spring 22 abuts against the bottom of the receiving hopper 1, and the bottom of each spring 22 abuts against the top of the base 4; a push rod 11 is provided at the bottom of the receiving hopper 1, and the travel switch 3 is installed on the top of the base 1 and is located below the push rod 11; the travel switch 3 is used to be electrically connected to an external alarm device. When the conveyor belt leaks, the receiving hopper 1 continuously receives the material falling from above. During this process, the receiving hopper 1 will continue to press down and contact the travel switch 3 until the signal of the travel switch 3 is triggered, so that the external alarm device reminds the staff that the leakage at this location has reached a warning state and needs to be dealt with in time. The utility model utilizes an adjusting nut 23 to adjust the compression stroke of the spring 22 and the distance between the push rod 11 and the travel switch 3, so as to control the receiving amount of the receiving hopper 1. The receiving hopper 1 will drop to the position that triggers the signal of the travel switch 3 only after receiving a certain amount of material. The device is small and light, easy to install, and can be placed below the position where the belt is prone to spillage. It can be used by connecting the power cord and the signal line. When the belt spills, the spilled material falls into the receiving hopper 1. When the spilled material reaches the weight set by the user, the corresponding signal can be output.

[0024] In this embodiment, the receiving hopper 1 is a funnel-shaped structure with a large opening and a small bottom. The funnel-shaped receiving hopper 1 can collect materials at the bottom so that the center of gravity is concentrated in the middle, making the device more stable when placed and receiving materials.
