Example Embodiment

[0031] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only the present invention. Some embodiments, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the protection scope of the present invention.

[0032] Such as Figure 1-3 As shown, this embodiment provides a material blockage detection device, which can be used in a vertically arranged material pipeline to detect whether blockage occurs at or above the device. The material jam detection device includes an induction probe 1, a rotating shaft 2, a proximity switch 3 and a controller 4. The sensing probe 1 is c...

Abstract

The invention relates to the technical field of detection devices, and discloses a material blockage detection device. The material blockage detection device comprises an induction probe rod, whereinone end of the induction probe rod extends into material flow; a rotating shaft is rotationally connected with the induction probe rod; a proximity switch in selective contact with the other end of the induction probe; a controller is electrically connected with the proximity switch and comprises a timing module and an alarm module; and falling material can toggle one end of the induction probe rod so that the other end of the induction probe rod is out of contact with the proximity switch. According to the material blockage detection device, the impact force generated by the material in the falling process is converted into an electric signal, once the blockage or the material falling is blocked, and the blockage or the blocking time is longer than a preset value, the alarm module gives an alarm, so that the abnormal process flow condition of the material blockage detection device or the upstream of the material blockage detection device is found in time, and the accident enlargementis avoided, so that the process flow smoothness is improved; and the induction probe rod is not prone to damaging, so that the service life of the material blockage detection device is long.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a material blockage detection device. Background technique [0002] In the production process of modern technology, the technology involved in material transmission (such as chemical enterprises, coal enterprises, ports, power plants, etc.), there is an unavoidable situation of material blockage. If the material is blocked, the production efficiency will be low, and if it is serious, the machine will be damaged, resulting in a large economic loss. Therefore, in the actual industrial production process, it is particularly important to monitor the material falling process and find material blockage in time. [0003] At present, pressure sensors installed in the material flow are mostly used to monitor material clogging. When there is a clog at the place where the pressure sensor is installed, the clogged material will squeeze the pressure sensor. When the pressure reache...
