The utility model relates to the technical field of pelletizing equipment, and discloses an adjustable pelletizing device which comprises a pelletizing table, the top side of the pelletizing table is fixedly connected with a U-shaped frame, the center of the top side of the U-shaped frame is in threaded connection with a T-shaped rod, the bottom end of the T-shaped rod is rotatably connected with a mounting cover, the bottom side of the mounting cover is fixedly connected with a pressing plate, and the pressing plate is fixedly connected with the top side of the U-shaped frame. The right side of the U-shaped frame is fixedly connected with a mounting plate, a pressing plate and a limiting plate are arranged, one or more material strips are placed on the top side of the pelletizing table, it is ensured that end openings of the placed material strips abut against the limiting plate, then the pressing plate is used for extruding and limiting the placed material strips from the top side, and therefore the material strips can be extruded and limited from the top side; at the moment, when the cutter carries out pelletizing operation, under the limiting effect of the limiting plate, the particle size cut every time can be kept the same, the situation that the particle size is not uniform is avoided, meanwhile, the pressing plate can prevent the material strips from tilting in the pelletizing process, and therefore it is guaranteed that the pelletizing operation is carried out normally.

The invention relates to the technical field of vacuum bag cleaning, and discloses a cleaning device for vacuum bag conveying, which comprises a rewinding machine and a rewinding frame, a continuous cleaning assembly is arranged between the rewinding machine and the rewinding frame, the continuous cleaning assembly comprises a cleaning shell, a cleaning screw rod and a driving part, the cleaning shell is fixedly connected between the rewinding machine and the rewinding frame, and the cleaning screw rod is fixedly connected between the cleaning shell and the rewinding frame. The side, close to the rewinding machine, of the cleaning shell is arranged to be trapezoid, when a vacuum bag passes through the cleaning shell, under the trapezoid structure, small dust is blown away by airflow through the guiding effect of an inclined face, primary cleaning of the surface of the vacuum bag is achieved, meanwhile, the cleaning lead screws located in the vertical direction rotate to conduct secondary cleaning on the vacuum bag, and in the rotating process of the cleaning lead screws, the cleaning lead screws can clean the surface of the vacuum bag. The contact area between the dust removal device and the vacuum bag is not large and continuous, the contact mode can effectively remove impurities and cannot damage the vacuum bag, dust and the impurities are easily brought to the two sides of the vacuum bag under the rotation effect, and impurity residues are effectively avoided.

A conveying device with a screening function for a pellet iron ore concentrate stock bin comprises a first-layer platform, an inclined platform and a conveying belt. The first-layer platform is horizontally arranged, and the inclined platform is obliquely arranged. And one end of the first-layer platform is connected with the higher end of the inclined platform. And a headstock is arranged at the side part of the other end of the first-layer platform. And a tailstock is arranged at the lower end of the inclined platform. And a middle support frame is arranged between the headstock and the tailstock. And a feeding roller and a driving roller are arranged on the headstock. And a tail roller is arranged on the tail frame. The conveying belt sequentially bypasses the feeding roller, the driving roller and the tail roller and then returns to the feeding roller along the middle supporting frame to form a closed loop. A sundry sieve is arranged on the side part of the headstock. And a feeding hole of the impurity sieve is connected with a discharging end of the conveying belt. And a stock bin is arranged below the impurity sieve. And an iron remover is arranged on the conveying belt and is positioned above the first-layer platform. According to the utility model, the pellet iron ore concentrate can be efficiently transported and stored, waste iron devices and waste sundries can be effectively removed before pelletizing or storage, and the purity of the iron ore concentrate is improved.

This invention relates to the application of microalgae polysaccharides in enhancing intestinal immunity in dairy cows, belonging to the field of feed technology. The microalgae polysaccharides prepared by this invention are used to increase the secretion of IgA, IgG, and IgM by the intestinal mucosa. This invention uses a specific ratio of kelp buds, Dunaliella salina, and Haematococcus pluvialis for pre-enzymatic hydrolysis using trypsin and nattokinase for a certain period of time, followed by enzymatic hydrolysis using hemicellulase and pectinase for a certain period of time. The resulting microalgae polysaccharide product has excellent effects in promoting the secretion of immunoglobulins in the dairy cow intestine, significantly increasing the content of IgA, IgG, and IgM in the dairy cow intestine, thereby enhancing intestinal immunity. It can serve as a highly effective alternative component for improving the intestinal immune function of dairy cows.
