The discharge end of the feeder is connected with a plurality of stirrers, and the discharge ends of the stirrers are connected with a finished product scale. The ingredient conveying equipment is high in conveying efficiency, free of residues and relatively concentrated in pipeline.

The application discloses a servo cut-off valve group, which comprises a first valve body and a second valve body integrated on a valve seat. Both the valve bodies are provided with valve cavities, and the valve cavities are internally provided with valve spools driven by a servo motor through a screw rod. The valve bodies are provided with outer ring channels communicated with inlet and outlet of the valve seat on the side surfaces, the outer ring channels are communicated with the valve cavities through a plurality of uniformly distributed lateral flow channels, and the inner walls of the valve cavities are further provided with inner ring channels. The longitudinal flow channels at the bottoms of the two valve cavities are communicated with each other through channels in the valve seat. When the two valve spools synchronously rise above the lateral flow channels, fluid can sequentially pass through the flow channels, and the valve is opened; when the two valve spools synchronously descend to completely cover the lateral flow channels, the valve is closed. The two valve cavities are communicated at the bottoms to form a pressure balance cavity, so that the valve spools are hardly subjected to axial thrust when the valve is closed, and high pressure is converted into sealing force in the radial direction of the valve spools, thereby fundamentally solving the high pressure leakage problem of traditional cut-off valves, and the application is especially suitable for high pressure equipment such as filter presses.

The utility model relates to the technical field of production feeding for nutritional fermented feed factories, in particular to a production feeding mechanism for nutritional fermented feed factories, which comprises a pasture crusher and a cyclone dust collector. A cyclone dust collector is arranged on one side of the forage grass crusher, the cyclone dust collector is connected with a U-shaped packing auger through an arranged connecting pipe, and the U-shaped packing auger is connected with a straw bin; a pneumatic conveying pipeline is arranged at a discharging opening in one side of the forage grass pulverizer and connected with a feeding pipe on one side of the cyclone dust collector through a connecting assembly and an auxiliary assembly, forage grass is beaten into the cyclone dust collector through the pulverizer by means of the pneumatic conveying pipeline and beaten into a U-shaped auger through an air seal machine, and the overall height of a workshop is controlled within M; the pneumatic conveying pipeline is large in conveying capacity, long in conveying distance, high in conveying speed, capable of loading materials at one position and then unloading the materials at multiple positions, capable of enabling the materials to run in a closed pipeline, free of dust raising and clean and tidy in environment. The energy consumption and the noise are low; and long-distance conveying can be realized.

This utility model discloses a conveying device for producing lactic acid bacteria beverages, including a conveyor frame. A conveying mechanism is installed at the upper center of the conveyor frame. A guide adjustment mechanism is installed on both sides of the conveying mechanism on the conveyor frame. The guide adjustment mechanism includes mounting plates symmetrically installed at the middle of the two side walls of the conveyor frame and a bidirectional lead screw installed between the two mounting plates. The advantages are: by installing the guide adjustment mechanism on the conveyor frame, this utility model enables the lactic acid bacteria beverage conveying device to not only adjust the spacing between the serpentine guide plates as needed under the action of the motor, the bidirectional lead screw, and the linkage rod, thus meeting the convenient conveying needs of lactic acid bacteria beverages of different sizes after filling, but also effectively increase the conveying capacity of the filled lactic acid bacteria beverages on the device under the action of the serpentine guide plates, meeting the high-efficiency conveying needs of large-volume filled lactic acid bacteria beverages.
