This invention discloses an intelligent powder packaging machine, relating to the field of powder packaging technology. The intelligent powder packaging machine includes a chassis, a bottom sealing mechanism, a vertical sealing mechanism, a feeder, a conveying pipe, a top sealing mechanism, a cutter, an extension component, a striking component, and a dust suppression component. During the powder filling process, the extension component prevents the conveying pipe from being too far from the bottom of the bag, thus preventing powder diffusion during the falling process. The extension component rotates during its descent or ascent, and the striking component strikes its outer wall during this rotation. The combined effect of centrifugal force and the striking action causes dust from the inner wall of the extension component to fall into the bag, preventing residual powder from escaping and causing contamination. Simultaneously, the dust suppression component sucks up any small amount of dust generated during the filling process after the powder is fully filled into the bag, preventing it from affecting the quality of the packaged product.

The utility model provides a phthalic anhydride production system which successfully solves the problem that residual materials at the bottom of a phthalic anhydride buffer tank cannot be completely emptied by reasonably designing pipelines and valve configuration. Specifically, a third pipeline is arranged in the system, is connected to an outlet in the bottom of the buffer tank and is provided with a first control valve, so that residual phthalic anhydride materials at the bottom of the buffer tank can be completely emptied through the pipeline in the production process; therefore, the problem that the phthalic anhydride quality is influenced by long-time shutdown or oxidation of residual materials in a traditional system is effectively avoided. Through the design, not only are the continuity and the stability of the phthalic anhydride production process improved, but also the quality of a final product is guaranteed, and the quality fluctuation problems of phthalic anhydride color value increase and the like are avoided. Meanwhile, the system simplifies operation, reduces manual intervention and improves production efficiency.

The utility model relates to the technical field of ceramic preparation, in particular to a mold for porous alumina ceramic preparation, which comprises a lower mold base and an upper mold base, a mold cavity is arranged in the middle of the top surface of the lower mold base, a detachable vertical rod is arranged on a bottom plate of the mold cavity, and a movable bottom plate matched with the mold cavity and slidably sleeved on a rod body of the vertical rod is arranged in the mold cavity. An extrusion die plate matched with the die cavity is arranged in the middle of the bottom face of the upper die base, guide rods are arranged at the two ends of the upper die base, the lower ends of the guide rods penetrate through the lower die base in a sliding mode and are provided with inward bending parts, and ejector rods capable of penetrating through a bottom plate of the die cavity are arranged on the top faces of the inner ends of the bending parts; the upper end of the guide rod is connected with the upper die holder, and the lower end of the guide rod penetrates through the lower die holder in a sliding manner, so that when the die is installed, the function of positioning the lower die holder and the upper die holder can be achieved, position deviation of the lower die holder and the upper die holder is prevented, and the function of convenient installation is achieved.

The utility model discloses a ball mill for cement production and processing, which relates to the technical field of cement processing and comprises a pair of supporting plates, a ball mill body is rotatably arranged between the supporting plates, a mounting frame is arranged on one side of the ball mill body, and a pre-crushing bin is arranged on the mounting frame. A first motor support is arranged on the pre-crushing bin, a first motor is arranged on the upper wall face of the first motor support, a crushing roller is arranged at the driving end of the first motor, a feeding hopper is arranged on the pre-crushing bin, and a first pressing block is arranged on the feeding hopper. And the caked raw materials in the pre-crushing bin are pre-crushed, so that the volume of the caked cement production raw materials is reduced, the situation that the raw material feeding speed is reduced due to the fact that the cement production raw materials block the feeding port of the ball mill body is avoided, and then the machining efficiency of the ball mill is improved.

This invention provides a pellet feed transfer robot for livestock farming, relating to the field of feed transfer. The livestock pellet feed transfer robot includes a storage cylinder, a discharge funnel fixedly connected to the bottom of the storage cylinder, multiple solenoid valves fixedly installed between the storage cylinder and the discharge funnel, and a feeding mechanism fixedly installed at the top of the storage cylinder. The feeding mechanism includes a protective cover installed on the top of the storage cylinder, a conveying pipe rotatably installed at the bottom of the feed inlet of the protective cover, and a filtering mechanism installed at the bottom of the conveying pipe for filtering feed passing through the conveying pipe. During the feeding stage, the conveying pipe rotates, connecting the discharge end of the conveying pipe with the storage cylinder. By adjusting the spacing of the baffles through the filtering mechanism in the feeding mechanism, it achieves the filtration of fragments in feed of different diameters. Combined with a vibration mechanism, it reduces feed blockage and cleans fragments from the surface of the baffles, solving the problem of mixed storage of fragments and whole feed, clogging the discharge port or solenoid valves, and reducing feed quality.
