Embodiment Construction
[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0035] It should be noted that when an element is said to be "disposed on, provided with" another element, it may be directly on the other element or there may also be an intermediate element. A component, it can be directly connected to another component or there may be an intermediate component at the same time. "Fixed connection" means fixed connection. There are many ways of fixed connection, which are not within the scope of protection of this article. The term used in this article "Vertical", "horizontal", "left", "right" and similar expressions are for the purpose ...

The invention discloses a self-induction constant pressure remote pneumatic conveying system for mine materials, comprising: a main conveying pipe for conveying materials in an intermediate warehouse, and an auxiliary air pipe for supplying air to the main conveying pipe is arranged side by side on one side of the main conveying pipe , the end of the main feeding pipe is connected with a mixer that mixes the material in the main feeding pipe with air force, and the end of the mixer is equipped with a nozzle that sprays out the material mixed in the mixer and air force in a slurry form when it meets water ; When the induced check valve monitors the pressure value in the main feeding pipe to rise, the pulse box will automatically open, and the gas in the auxiliary air pipe will enter the main feeding pipe for gas replenishment, blowing plugging and pressure stabilization. When the pressure of the main feeding pipe recovers After setting the value, the pulse box will stop automatically, and the auxiliary air pipe will stop supplying air; including the air inlet pipe connected to the quantitative feeding device at the bottom of the intermediate bin, when the material enters the feeding device evenly, the air force will send the quantitative feeding device at the bottom of the intermediate bin The set material is blown out so that the material can be conveyed smoothly.
Description
technical field [0001] The invention relates to the technical field of pneumatic conveying systems, in particular to a remote pneumatic conveying system for self-induction constant pressure mine materials. Background technique [0002] Material transportation has always been a relatively large part of industrial applications, and the environmental protection, efficiency and energy consumption of powdery materials are the key issues to be solved. At present, mechanical conveying methods include belt conveyor, vibrating conveyor, bucket conveyor and screw conveyor, which are more suitable for open-air or large-volume material transportation, with poor dust control, high material damage rate, limited conveying distance, and difficult maintenance. [0003] Pneumatic conveying uses the energy of airflow to transport powdery materials along the direction of airflow in a closed pipeline, which is a specific application of fluidization technology. Pneumatic conveying system has the...
