Technical Field

[0001] The utility model relates to the technical field of powder material transportation, in particular to a pneumatic conveying system for a lifting feeder. Background Art

[0018] Reference will now be made in detail to embodiments of the present disclosure, one or more examples of which are set forth herein below. Each embodiment and example is provided by explaining the apparatus, composition and materials of the present disclosure, rather than limiting. On the contrary, the following description provides a convenient illustration of an exemplary embodiment for implementing the present disclosure. In fact, it will be clear to those skilled in the art that various modifications and variations can be made in the teachings of the present disclosure without departing from the scope or spirit of the present disclosure. For example, a feature shown or described as a part of an embodiment can be used in conjunction with another embodiment to produce yet another embodiment. It is expected that the present disclosure covers such modifications and variations within the scope of the appended claims and their equivalents. Other objects, features and aspects of the present disclosure are disclosed in or clear from the following detailed description. It will be understood by those of ordinary skill in the art that this discussion is only a description of exemplary embodiments and is not intended to limit the wider aspects of the present disclosure.

[0019] like Figure 1The utility model shows a pneumatic conveying system of a lifting feeder disclosed in the utility model, comprising an ash hopper 1, an elevator 2 and a silo 3. The ash hopper 1, the elevator 2 and the silo 3 are connected through a closed pipeline. A pneumatic conveying mechanism for conveying the material in the ash hopper 1 to the elevator 2 is arranged at the outlet end of the lower end of the ash hopper 1. The pneumatic conveying mechanism comprises a fan 4 and a conveying pump 5 which are connected to each other. The fan 4 adopts a Roots blower, which can be continuously pressurized to meet the needs of long-distance material transportation. The outlet end of the conveying pump 5 is connected to the discharge end of the ash hopper 1. A rotary feeder 10 for discharging is arranged at the lower end of the ash hopper 1. The material is conveyed to the outlet end of the conveying pump 5 through the rotary feeder 10. A material-gas separation mechanism is arranged on the pipeline between the ash hopper 1 and the elevator 2.

[0020] The material of the utility model is in a closed state during pipeline transportation, thereby preventing the material from absorbing moisture, being contaminated or mixed with other impurities during transportation. Through pneumatic conveying and cooperation with the elevator, compared with the direct use of curved pipe lifting and transmission, the utility model can greatly reduce pneumatic consumption and ensure smooth transportation.

[0021] Specifically, the material-gas separation mechanism of the utility model includes a material-gas separation bin 6 and an ash bin 7 arranged at the lower end of the material-gas separation bin 6. A chute 8 is arranged at the lower part of the ash bin 7, which is connected with the hopper of the elevator 2 through the chute 8. After the material is separated from the air, the material falls to the hopper of the elevator 2 in the ash bin 7 by gravity, and basically moves under the action of gravity in the ash bin 7, thereby reducing gas consumption and ensuring smooth transportation of materials.

[0022] In order to ensure the working environment, a dust collector 9 for removing dust from the gas can be connected to the gas outlet end of the material-gas separation bin 6 of the utility model to meet the energy-saving and environmental protection requirements of the on-site environment.
