The application relates to the technical field of powder production and processing equipment, in particular to a flow guide device for airflow mill pulverization and a pulverizer adopting the flow guide device, wherein the flow guide device for airflow mill pulverization comprises a device body, a flow guide area, a collection area and a drainage area are formed in the device body, and the collection area and the drainage area are distributed around the flow guide area; when the device body is matched with a pulverization cavity and the pulverization cavity is in a working state, airflow sprayed from a nozzle flows to the lower part of the collision area after collision in the middle of a pulverization area and then flows into the flow guide area and the drainage area in sequence; the collection area collects coarse particles sinking downwards, the collection area is formed with an opening, coarse particles in the collection area can flow out through the opening, the flowed-out coarse particles can flow into the drainage area together with airflow and flow out of the drainage area; the flowing direction of airflow flowing out of the drainage area is towards the top of the pulverization cavity. The flow guide device for airflow mill pulverization can improve powder preparation efficiency and improve the vortex state at the bottom of the pulverization cavity.

The diversion tunnel flood discharge structure comprises a diversion tunnel, a flood discharge pipe, a pressurizing pipe and an air compressor, the flood discharge pipe is fixedly arranged, one end of the flood discharge pipe is connected with the water outlet end of the diversion tunnel, the other end of the flood discharge pipe is connected with a river channel, one end of the pressurizing pipe is connected with the flood discharge pipe, and the other end of the pressurizing pipe is connected with the air compressor. The inner diameter of the pressurizing pipe is smaller than that of the flood discharge pipe. The diversion tunnel flood discharge structure is simple in overall structure, high in flood discharge efficiency and low in construction difficulty and cost.

The application discloses a big data table hash connection hardware acceleration method and device, equipment and medium, and relates to the database heterogeneous acceleration field. The method is applied to an acceleration board card and comprises the following steps: receiving a connection operation type instruction; applying a first memory space of a first to-be-connected data table and a second memory space of a second to-be-connected data table respectively by using a connection table size instruction, so as to store each first shard of the first to-be-connected data table into the first memory space and store each second shard of the second to-be-connected data table into the second memory space; and performing hash connection calculation on each first shard in the first memory space and each second shard in the second memory space according to the connection operation type instruction and a preset parallel processing row number, so as to obtain corresponding connection table row data. Through the above scheme, the hash connection hardware acceleration effect can be effectively improved.
