The invention belongs to the technical field of hydraulic machinery, and relates to an anti-backflow air entrainment cavitation reduction device which comprises a gas channel, one end of the gas channel is communicated with a gas source, and the other end of the gas channel is provided with an anti-backflow assembly; the anti-backflow assembly comprises n baffles and n springs, and the n baffles are all hinged to the inner wall face of the gas channel; the n baffles are encircled to form a shielding part for shielding an outlet of the gas channel; one end of a spring is fixedly connected to one side, away from the gas source, of a baffle, and the other end is fixedly connected to the inner wall surface of the gas channel. By means of the mode that the n baffles are encircled to form the shielding part, the n baffles are separated under the condition that gas pressure is enough, the shielding part is opened, and gas smoothly passes through for aeration; when the gas pressure is insufficient, the n baffles are encircled, the shielding part can be automatically closed, and liquid in the hydraulic machinery is prevented from flowing back.

The adjustable ceramic air supply device comprises a pulverized coal pipe, the pulverized coal pipe is sleeved with and fixedly provided with an annular piece, the pulverized coal pipe is sleeved with and communicated with a discharging pipe, the discharging pipe and the annular piece are connected through a plurality of fastening bolts, and the upper end of the discharging pipe is communicated with and fixedly provided with an air inlet pipe. An annular sliding groove is formed in the pulverized coal pipe, a movable part is arranged in the discharging pipe, and one end of the movable part extends into the annular sliding groove and is arranged in the annular sliding groove in a sliding mode. According to the adjustable ceramic air supply device for pneumatic conveying of pulverized coal, air flow is discharged through a gap between the movable part and the discharging pipe and is mixed with pulverized coal in the pulverized coal pipe, and a generated material column can be damaged; the long-distance stable conveying effect is achieved, the device is used in the pneumatic conveying process of the pulverized coal, the high-concentration pulverized coal discharged from the injection tank is diluted, solid and gas are fully and evenly mixed, the pulverized coal and the gas form a stable concentrated-phase solid-gas two-phase flow, long-distance, high-concentration and large-injection-quantity conveying of the pulverized coal is facilitated, and the device is key equipment for long-distance concentrated-phase conveying of the pulverized coal.

The application discloses a high-voltage bushing transport adjustable damping type shock-absorbing support frame and relates to the technical field of high-voltage bushing transportation.The high-voltage bushing transport adjustable damping type shock-absorbing support frame comprises a support and a shock-absorbing component, each shock-absorbing component comprises a base, the base is supported on a mounting base surface, a spring seat, the spring seat is arranged above the base and fixed on the support, a coil spring, the coil spring is connected with the base and the spring seat at two ends respectively, and a damper, the damper comprises a pressure cylinder and a flow rate regulating valve, the pressure cylinder is arranged in the coil spring in a spaced mode, a cylinder body of the pressure cylinder is fixed on the base, a piston rod top end is fastened with the spring seat through locking pieces, and the flow rate regulating valve is installed on a fluid passage of the pressure cylinder to regulate the flow rate of fluid in and out of the pressure cylinder.Through the flow rate regulating valve, the flow rate of fluid in the pressure cylinder can be regulated, the rigidity of the pressure cylinder is further regulated, the damping size of the coil spring is regulated, different transportation conditions can be adapted, and the safety and stability of the high-voltage bushing transportation process are ensured.

The utility model relates to the technical field of feeding equipment, in particular to a constant-temperature speed-adjustable liquid incense base feeding device, which comprises a material tank, a temperature control mechanism and a pressure control mechanism, the material tank is internally provided with a liquid storage cavity for storing liquid incense bases, and the temperature control mechanism and the pressure control mechanism are arranged on the material tank. When the liquid incense base in the liquid storage cavity is output to the next procedure through the discharging port formed in the bottom of the charging bucket, the temperature of the liquid incense base stored in the liquid storage cavity is controlled through the temperature control mechanism, so that the temperature of the liquid incense base output from the discharging port is kept consistent, and then the liquid incense base output from the discharging port is controlled by controlling the pressure in the liquid storage cavity. Therefore, the flow rate of the liquid base output from the discharge port is controlled. When the liquid essence base in the liquid storage cavity is output to the next process, through the temperature control mechanism and the pressure control mechanism, it is ensured that the output liquid essence base has the stable temperature and the adjustable flow speed, the processing quality of the powder essence for food is improved, and waste and loss in the production process are reduced.
