The application relates to the field of piezoelectric pumps, in particular to a micro-nano piezoelectric air pump with air inlet and outlet on the same surface, which comprises a rack mechanism, an oil tank, an engine, a battery assembly and a silencer which are sequentially installed on a rack body, a moving piece located outside the rack body, a shell piece arranged outside the oil tank, a control piece arranged on the top of the shell piece and a tool box installed on one side of the shell piece. The piezoelectric ceramic prepared by adopting the micro-nano process is combined with the laser welding assembly mode instead of the adhesive assembly mode, so that the reliability risk of the aging of the adhesive layer and the decrease of the bonding force in the high-temperature, high-humidity and low-temperature environment is avoided, the air tightness and long-term consistency between the layers are ensured, and the durability of the product under the harsh working conditions such as vibration and mechanical impact is remarkably improved. Thirdly, the air inlet, the air outlet and the air exhaust are completed on the same structure surface, the flow path layout and the number of parts are simplified, and the assembly complexity and the cost are reduced.

The application relates to a feedback device for a steam sterilization and maturation equipment, and belongs to the technical field of feed processing equipment. The device comprises a temperature measuring mechanism, a material containing mechanism, a conversion mechanism and a control mechanism. The temperature measuring mechanism is arranged in a sterilization and maturation tank and is used for detecting the temperature of feed. The material containing mechanism is arranged below the sterilization and maturation tank and is used for receiving the feed in the sterilization and maturation tank. The conversion mechanism is arranged below the outlet of the sterilization and maturation tank and above the material containing mechanism and the input end of a conveying mechanism. The conversion mechanism is used for selectively connecting the outlet of the sterilization and maturation tank with the material containing mechanism or the input end of the conveying mechanism. The control mechanism is electrically connected with the sterilization and maturation tank, the temperature measuring mechanism and the conversion mechanism. The application can solve the problem of excessively high maturation degree of feed after sterilization and maturation.

A low-NOx ammonia-coal stable combustion swirl burner relates to the field of clean combustion of coal with low carbon and low NOx. This invention addresses the problems of ammonia slip and high NOx emissions in existing ammonia-coal co-combustion technologies. In this invention, a primary air / pulverized coal duct is fitted onto a central NH3 duct, forming a primary air channel between them. An outer NH3 duct is fitted onto the primary air / pulverized coal duct, forming an NH3 channel between them. An inner secondary air duct is fitted onto the outer NH3 duct, forming an inner secondary air channel between them. An outer secondary air duct is fitted onto the inner secondary air duct, forming an outer secondary air channel between them. Tangential and axial blades are respectively installed in the inner and outer secondary air channels. This invention is used for pulverized coal swirl combustion.

This utility model discloses a pneumatic high-viscosity lubricating oil refueling device, comprising: an oil tank, which is a cavity with an opening at the top, a sealing cap installed at the top of the oil tank, and a discharge pipe installed at the bottom of the oil tank; a pressure pipe, which is placed on one side of the oil tank, an air filter installed at one end of the pressure pipe, and a diversion pipe connected to the sealing cap fixed in the middle of the pressure pipe. The beneficial effects of this utility model are: by connecting the pressure pipe to a high-pressure gas source, compressed air is used to pressurize the inside of the oil tank, so that the high-viscosity lubricating oil is discharged from the discharge pipe under pressure; solenoid valves are installed on the outside of the diversion pipe and in the middle of the pressure pipe. By controlling the opening and closing of the solenoid valves, the flow direction of compressed air can be flexibly controlled, realizing the switching between different operations such as pressurizing the oil tank and pressurizing the inside of the sealing cap, thus meeting different working needs.
