The system has small output and poorer economy when the system is transported for a long distance. The pipeline is many, takes up an area of more, arranges the difficulty, and the system reliability is relatively poor.
An internal bypass (double-sleeve) pneumatic conveying system is an advanced pneumatic conveying technology developed abroad in the 80 th century. The developed internal bypass turbulent dense-phase pneumatic conveying system changes the working conditions of low concentration, high flow speed, high abrasion, easy pipe blockage and high energy consumption in conventional positive-pressure conveying, finds an ideal alternative scheme for solving the problems of high output and dense-phase conveying of high-abrasion materials, and completely realizes the localization. The inner bypass ash conveying pipeline and various valves and pipeline accessories arranged on the pipeline jointly form a set of complete inner bypass turbulent flow dense-phase pneumatic conveying system. The ash mixer is a key pipeline accessory.

The technical scheme of the utility model: the utility model provides an interior bypass turbulent flow dense phase pneumatic conveyor system is with mixing grey ware, is including mixing grey ware body, mix the inside defeated ash pipe that is equipped with of grey ware body, mix grey ware body one end and pass through defeated grey female pipe of defeated union coupling, mix the grey ware body other end and connect and defeated grey union coupling through a shrinkage, the last circular steel welding that has a plurality of slant water conservancy diversion strips that has of defeated grey pipe, be connected with the intake pipe on mixing grey ware body lateral wall, mix grey ware body, defeated grey pipe and shrinkage and connect between formation gas cavity.
Preferably, the ash mixer body is a horizontally arranged seamless pipe, the air inlet pipe is vertically connected to the ash mixer body, and the contraction joint is welded on the ash mixer body.
Preferably, the top of the air inlet pipe is provided with an air inlet pipe connecting flange, and two ends of the ash conveying pipe are provided with ash conveying pipe connecting flanges.
Preferably, one end of the ash mixer body is connected with the ash conveying pipe through a connecting ring.
Preferably, the length of the oblique flow guide strip is matched with the length of the gas chamber.
The utility model discloses well intake pipe passes through intake pipe flange and air supply pipe connection, and defeated ash pipe passes through defeated ash union coupling flange and defeated grey female union coupling. The pipeline flanges are connected by flanges, so that the installation and the maintenance are convenient. The temperature difference of the main ash conveying pipeline is basically stable, the thermal expansion and the cold shrinkage are reduced, the flange connection is leak-free, and the safety and the reliability are realized.
The utility model provides an ash conveying pipe is actually for mixing the ash inlet of ash ware, and the ash in the ash conveying main pipe is sent into through ash conveying pipe and is mixed the ash ware. The ash conveying pipe is welded with a guide strip with a certain inclination by round steel. The gas entering the ash mixer from the gas inlet pipe flows to the outlet of the ash mixer along the diversion strips, and is mixed (contracted and connected) with the fly ash sent by the ash conveying pipe at the outlet of the ash mixer. The guide strips arranged on the ash conveying pipe enable compressed air entering the ash mixer to flow to the outlet of the ash mixer along a certain inclination angle on one hand, and increase the disturbance of air flow on the other hand, so that the compressed air and fly ash are in a flowing state after being mixed.
The contraction joint increases the air flow speed of the obtained air chamber, forms certain impact and fluidization effect on fly ash, pushes the air-ash mixture to flow forward, and prevents pipe blockage.
The utility model discloses an intake pipe lets in the air and increases the defeated air output, makes the ash intensive mixing that air and defeated ash pipe carried, adjusts grey gas to appropriate concentration ratio, improves conveying capacity, eliminates "stifled pipe" and sprouts the state for carry smoothly, not stifled pipe.
