The energy-saving efficient pellet material drying, preheating and roasting production line comprises a chain grate machine, a rotary kiln and an annular cooler, a kiln head bin of the rotary kiln is connected with one end of an annular cooling bin of the annular cooler in a sealed mode, and an inclined sliding plate is arranged in the kiln head bin; high-temperature pellets in the rotary kiln fall onto the cooling conveying plate chain through the inclined sliding plate, a roundabout fresh air heat exchange channel is arranged in the inclined sliding plate, and fresh air enters the fresh air heat exchange channel through the fresh air guide-in pipe under the power of the fresh air conveying fan and then enters the cooling conveying plate chain through the fresh air guide-in pipe. Fresh air exchanges heat with the high-temperature pellets on the inclined sliding plate in the fresh air heat exchange channel, and after heat exchange, the fresh air is guided into the heat exchange fresh air drying section of the chain grate through the hot air conveying pipe to dry the green pellets. The inclined sliding plate is additionally arranged in the kiln head bin of the rotary kiln, has a material guiding function and can effectively prevent generation of hydrogen chloride gas in the chain grate; and more importantly, the drying efficiency of the chain grate machine is also improved.

The motor is fixedly installed on the treatment barrel, the stirring rod is connected to the output end of the motor, the connecting plate is arranged on the stirring rod, a filtering assembly is arranged at the bottom of the treatment barrel and comprises a discharging pipe, a filtering box and a feeding hopper, the discharging pipe is installed at the bottom of the treatment barrel, a valve is arranged on the discharging pipe, and the filtering box is connected with the discharging pipe. And the filter box is arranged at the bottom of the discharge pipe, so that the technical problems that urea and other components in a solution cannot be uniformly mixed and the use effect of the solution and the efficiency of a catalytic reduction reaction are influenced due to the fact that an effective stirring mechanism is generally lacked in an existing recovery device mentioned in the background technology are solved.

This invention discloses a system and method for water replenishment and exchange through multi-gate coordinated control, comprising: a river channel; and a first control gate assembly and a second control gate assembly respectively disposed in the upstream and downstream sections of the river channel, and further comprising multiple channels disposed in the river channel and positioned between the first and second control gate assemblies. This invention utilizes natural tidal energy to replenish and exchange water in the inland river channel through multiple gates, while simultaneously and rationally coordinating the opening and closing of the upstream and downstream first and second control gate assemblies, thereby ensuring a long-term unidirectional flow state in the inland river channel, increasing water circulation, and ultimately improving the water quality of the inland river channel.

The utility model provides a radiator double-straight-seam welding device, which relates to the technical field of radiator processing, and comprises a box body, a cold air conveying assembly is fixedly connected to one side outside the box body, the cold air conveying assembly comprises an air inlet box, one side of the air inlet box is fixedly connected to the box body, and the other side of the air inlet box is fixedly connected to the box body. An air suction device is installed at the end, away from the box body, of the air inlet box, a cold air box is fixedly connected to the top end of the box body, fins are fixedly connected to the inner wall of the cold air box, and a semiconductor chilling plate is fixedly connected to the top end of each fin. According to the utility model, direct and effective air cooling is provided, so that the cooling efficiency and the welding speed are greatly improved, the whole welding process is further optimized, impurities, particulate matters and harmful gases in the air in the air bellow are adsorbed, and when the purification effect of the activated carbon is poor, the activated carbon of the filter assembly can be replaced, so that the production cost is reduced. Operation is simple and convenient.

The application discloses a satellite network routing update method and system, electronic equipment and storage medium, and mainly solves the problem that non-landing satellite configuration data is lost in the transmission process due to link failure, leading to routing sending failure or loop. The routing update method provided by the application quickly and reliably converges the routing. The method comprises the following steps: (1) refreshing topology data after receiving satellite failure, calculating the shortest path from the gateway station to the satellite based on the minimum hop strategy; determining the home gateway station of the satellite and recording the corresponding shortest path length; (2) dividing the satellites into different batches according to the shortest path length, and completing the satellite routing update in batches from near to far; (3) sending routing update instructions to a plurality of satellites in the same batch in a concurrent manner, and forwarding only through the updated node or gateway station direct path.

This invention discloses a top-drive type tailpipe cementing head, a tailpipe cementing system, and a cementing process. The cement head body comprises a cement head body, a rubber plug pre-installation mechanism, and a drill pipe tandem connector. The cement head body is used to connect to the top drive system at its upper end. At least one union joint is milled on the cement head body. The cement head body has an internal cavity. The rubber plug pre-installation mechanism is installed within the cavity. The rubber plug pre-installation mechanism includes a rubber plug sleeve and a drill pipe rubber plug. A fluid channel is provided on the side wall of the rubber plug sleeve. The drill pipe rubber plug is installed inside the rubber plug sleeve. The drill pipe rubber plug is used to scrape the drill pipe under the action of displacement fluid. The drill pipe tandem connector is connected to the lower end of the cement head body. The drill pipe tandem connector is used to connect the drill pipe string. This invention solves the problem of the need for multiple connection and disassembly of conventional cement heads in tailpipe cementing; solves the circulation problem of the top drive system under drill pipe rubber plug pre-installation; and solves the problem of continuity of tailpipe cementing construction throughout the entire process.
