Fault detection system for pneumatic conveying of household garbage

Abstract

The invention discloses a fault detection system for pneumatic conveying of household garbage. The fault detection system for pneumatic conveying of household garbage comprises a fault detection module which is connected with a main control server, the main control server is connected with a fault removal module, the fault detection module comprises a plurality of pipe pressure meters which are each connected with an alarm, the fault removal module comprises a pressurizing deblocking module and a mechanical deblocking module, the mechanical deblocking module comprises a base, a fixed rod is installed in the base in a sliding mode and provided with a first through hole, a movable rod is installed in the first through hole in a sliding mode, one end of the movable rod extends out of the first through hole, and the end, outside the first through hole, of the movable rod is provided with a taper drill bit. According to the fault detection system for pneumatic conveying of household garbage, the taper drill bit can be conveniently and rapidly pushed into a pipeline through a transmission module, the dredging efficiency is greatly improved, the movable rod can be effectively protected through a buffer module, and thus the service life of the movable rod is prolonged.

Description

technical field [0001] The invention relates to the technical field of pneumatic conveying, in particular to a fault detection system for pneumatic conveying of household garbage. Background technique [0002] Pneumatic conveying, also known as airflow conveying, uses the energy of airflow to convey granular materials along the airflow direction in a closed pipeline. It is a specific application of fluidization technology. The pneumatic conveying device has a simple structure and is easy to operate. , Vertical or oblique direction of transportation, during the transportation process, physical operations such as heating, cooling, drying and air classification of materials or some chemical operations can also be carried out at the same time. [0003] Patent No. 200510200280.1 Pneumatic conveying system automatic blockage removal method and device invention patent discloses a pneumatic conveying system automatic blockage removal method and device, which includes a pressure vess...
