Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1 and 2, a material conveying pipeline comprises a conveying pipe body 1, wherein the conveying pipe body 1 is vertically arranged, a first control valve 2, a metering device 3 and a second control valve 4 are sequentially arranged in the conveying pipe body 1 from top to bottom to control the on-off of the conveying pipe body, and the first control valve 2, the metering device 3 and the second control valve 4 are all connected with a controller 5.
The working process of the embodiment is as follows: in the working process, the first control valve 2 is firstly closed, materials are collected, after a certain amount of materials are collected, an instruction is sent to the first control valve 2 through the controller 5 to enable the first control valve 2 to be in an open state, the materials fall into the metering device 3 to be metered, the first control valve 2 is closed at the same time, after metering is completed, the metering device 3 is controlled by the controller 5 to unload the materials, the materials fall into the second control valve 4, the second control valve 4 is controlled by the controller 5 to be opened, the second control valve 4 is closed after unloading of the materials on the second control valve 4 is completed, one-time material conveying and metering actions are completed, the steps are repeated, and conveying and metering of the whole materials are achieved.
This embodiment can master in real time the interior material of pipeline and carry the condition and add up the statistics to the material volume, when taking place the pipeline jam, can in time know, easily pipeline's maintenance.
Referring to fig. 1, in some embodiments, an air inlet 6 is formed on the conveying pipe body 1 below the second control valve 4, and the bottom end of the conveying pipe body 1 is connected to a negative pressure fan (not shown).
This embodiment is equipped with negative-pressure air fan on carrying body 1, and the material that falls from second control valve 4 can be fast followed and carried body 1 output under the negative pressure is drawn, simultaneously because of being provided with second control valve 4, therefore the negative pressure is little to metering device 3 influence.
It can be understood that, in consideration of the negative pressure adsorption effect, the air inlet 6 is disposed close to the second control valve 4, and the air inlet 6 is uniformly distributed in plurality in the circumferential direction of the cross section of the conveying pipe body 1. This embodiment is because of air intake 6 is close to second control valve 4 and sets up, therefore can discharge in the timely quick follow conveying pipe body 1 of the material that second control valve 4 unloaded, and air intake 6 is a plurality of along 1 cross section circumferencial direction equipartitions of conveying pipe body, then can guarantee absorbent uniform stability.
