Embodiment Construction
[0035] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings of the embodiments.
[0036] In the present invention, the conveying pipeline is arranged in upper and lower layers, even if the lower pipeline is blocked by accumulated material, the accumulated material can still be transported by the upper pipeline, thereby ensuring the normal operation of the entire conveying system.
[0037] see image 3 , self-dragging material conveying system of the present invention, it comprises feed bin 21, and the top of feed bin 21 is provided with filter bag 213, and the top of feed bin 21 is provided with filter bag blowback system 212 (with instrument air blowback);
[0038] The hopper 26 contains the conveyed material;
[0039] Material conveying lower pipeline 23, its inlet end communicates with hopper 26 through hopper outlet door 25 (electric or pneumatic valve), conveys the material in the hop...

The invention relates to a self-dredging material conveying system and a self dredging method thereof. The problem that existing material conveying systems are blocked is solved. The self-dredging material conveying system comprises a stock bin, a hopper, a lower material conveying pipeline, an upper material conveying pipeline and a negative pressure fan, wherein the inlet end of the lower material conveying pipeline communicates with the hopper through a hopper outlet door, the outlet end of the lower material conveying pipeline communicates with the stock bin through a lower pipeline outlet door, and a pressure detector is arranged in the lower material conveying pipeline; the upper material conveying pipeline is arranged above the lower material conveying pipeline in parallel and communicates with the lower material conveying pipeline through a plurality of communication pipes, and the outlet end of the upper material conveying pipeline communicates with the stock bin through an upper pipeline outlet door; and the negative pressure fan communicates with the upper portion of the stock bin through a stock bin outlet pipeline, so that negative pressure air currents are generated in the lower material conveying pipeline and the upper material conveying pipeline. The hopper outlet door, the negative pressure fan, the lower pipeline outlet door, the upper pipeline outlet door and a stock bin inlet and outlet door are all controlled by a controller. According to the self- =dredging material conveying system and the self dredging method thereof, a conveying pipeline is arranged to be of a two-layer structure in the vertical direction, during normal operation, materials are conveyed through the lower material conveying pipeline, and during blocking, the materials are conveyed by the upper material conveying pipeline, so that the self dredging function of the material conveying system is achieved.
Description
technical field [0001] The invention relates to an anti-clogging technology for a material conveying system, in particular to a self-dragging material conveying system and a self-dragging method that is suitable for a negative-pressure pneumatic conveying system and can be self-dredging when the internal blockage of the system pipeline occurs. Background technique [0002] The negative pressure pneumatic conveying system is a system that uses the energy of the air to transport materials, specifically refers to the system that uses the kinetic energy of air with a certain speed to transport materials. [0003] In this type of conveying system, pipeline blockage is one of the most common and most unhandy failures of the pneumatic ash conveying system, accounting for more than 60% of the failure rate of the pneumatic ash conveying system. [0004] see figure 1 , the structure of the existing material delivery system is as follows: the material in the hopper 15 enters the mater...
