This invention provides a method for producing single-cell protein using a mixed bacterial culture, comprising the following steps: performing primary seed culture on methanogenic bacteria, *Tricholoma materata*, and *Glucosinolate methyl-eating bacteria* to obtain primary seed solutions; mixing the primary seed culture solutions evenly to obtain a mixed bacterial solution; inoculating the obtained mixed bacterial solution into a secondary seed culture medium for cultivation to obtain a secondary seed solution; inoculating the obtained secondary seed solution into a fermentation medium for scale-up cultivation to obtain a fermentation broth; separating the solid and liquid components of the obtained fermentation broth, harvesting the bacterial cells, and obtaining single-cell protein. This method for producing single-cell protein using a mixed bacterial culture improves the utilization rate of the carbon source methane and the yield of single-cell protein.

The application relates to a manufacturing method of a head structure of a carbon fiber composite material-based aerodynamic push rod, which comprises the following steps: dividing the head structure into five parts, i.e. a circular truncated cone-shaped upper shell, an inverted circular truncated cone-shaped lower shell, a supporting pipe, a flange seat and a circular truncated cone-shaped protective sleeve; setting a first thickened area and a second thickened area in the upper shell; setting a third thickened area and a fourth thickened area in the lower shell; adopting carbon fiber prepreg to carry out multi-layer pasting on the upper shell, and then inserting multi-layer carbon fiber prepreg into the multi-layer interval of the first thickened area and the second thickened area for pasting; adopting carbon fiber prepreg to carry out multi-layer pasting on the lower shell, and then inserting multi-layer carbon fiber prepreg into the multi-layer interval of the third thickened area and the fourth thickened area for pasting; adopting carbon fiber prepreg to carry out multi-layer pasting on the supporting pipe, and then carrying out curing and forming through a hot pressing tank process after the pasting is completed. According to the head structure requirements, reasonable optimization design of prepreg layer angle, layer sequence and layer proportion is carried out, the head structure bearing requirements are met, and overall weight reduction is realized.

The utility model relates to composite bag processing technical field especially is a kind of composite bag welding nozzle heat sealing device for food, including bearing plate, the top of bearing plate is separately provided with heat sealing assembly and auxiliary assembly, auxiliary assembly is located at the bottom of heat sealing assembly, by setting up installation top plate, driving motor, threaded rod, moving block, spring telescopic link and the cooperation use of heat sealing knife, the sealing of heat sealing device to composite bag different position is realized, the flexibility of device is improved, driving motor is installed in the end of installation top plate, driving threaded rod rotates, threaded rod is connected with moving block screw thread, so that moving block can move along its axial direction under the rotation of threaded rod, one end of spring telescopic link is connected in moving block, other end connects heat sealing knife, the setting of spring telescopic link makes heat sealing knife have certain buffer capacity in moving process, can adapt to composite bag of different thickness, guarantee heat sealing effect.
