The invention discloses a multi-section fixed bed reactor and application thereof. The fixed bed reactor comprises a plurality of sections of reaction units which are connected in series in the vertical direction, and static mixers arranged between the adjacent reaction units, the reaction unit comprises a reactor and a redistributor positioned above the reactor; a mixing component is arranged in the static mixer, and a heat preservation shell pass is arranged outside the mixing component; the inlet of the static mixer is communicated with the outlet of the reactor of the previous section of reaction unit and the raw material supplementing pipe, and the outlet of the static mixer is communicated with the redistributor of the next section of reaction unit. After each section of reactor discharges, materials are automatically supplemented, mixed and subjected to heat preservation, and then are distributed into the next section of reactor, so that the raw materials can be fully mixed and uniformly distributed. The equipment is simple to operate, and stable, continuous and efficient in production.

This invention provides a continuous preparation device for chlorine dioxide slow-release microspheres, belonging to the field of mechanical device technology. It solves the problems of existing commercially available chlorine dioxide preparation devices, where dust easily comes into contact with the chlorite solution and polymer solution during continuous production, causing a decline in chlorine dioxide quality; and the inaccurate and unstable delivery of the feeding equipment to the designated position during the placement and collection of chlorine dioxide slow-release microspheres, resulting in product loss. This continuous preparation device for chlorine dioxide slow-release microspheres includes a body, a frame, and a base. The body, located at the top of the base, has a rotating unit for loading materials and a preparation unit on one side of the rotating unit. The preparation unit and the rotating unit are separated by a glass plate. Two symmetrical openings are located at the bottom of the glass plate, and a limiting seat is provided at the opening within the preparation unit. This invention has the advantages of dust prevention and continuous manufacturing.

The invention discloses a pipe drawing and welding forming integrated manufacturing process for a plastic bucket. The process comprises the following steps that S1, a pipe drawing blank is prepared, specifically, a continuous plastic pipe is extruded through pipe drawing equipment; s2, a fixed-length cutting process: conveying the continuous plastic pipe extruded by the pipe drawing equipment to cutting equipment; s3, workpiece positioning and clamping are conducted, specifically, the cut barrel body blank, a preset base and a barrel cover are transferred to welding equipment; s4, inner side support arrangement; and S5, heating welding forming: passing through a heating structure of welding equipment. The problems that a traditional blow molding process is low in efficiency, uneven in barrel body wall thickness, high in mold cost, difficult in model changing and high in material loss and energy consumption are solved; through the modes of extrusion molding, fixed-length cutting and hot melting welding, efficient continuous production is achieved, it is guaranteed that the wall thickness of the barrel body is uniform, the structural strength is stable, no complex mold is needed, production of products of various specifications can be rapidly adapted, the production cost is remarkably reduced, and the device is especially suitable for large-size containers.

This invention relates to the field of fiber preparation technology and discloses a highly efficient method for preparing flame-retardant monofilaments. The method includes: surface activation of a polyamide matrix using radio frequency plasma to directionally introduce carboxyl functional groups; surface grafting modification of a composite flame-retardant masterbatch using a silane coupling agent to construct an interfacial transition layer; controlling the moisture content of the raw materials using a microwave-airflow combined drying system; achieving a gradient distribution of the flame retardant using a dual-channel spinning assembly; synergistically dispersing the nano-reinforcing phase and the flame retardant to construct a three-dimensional network structure, and forming nascent monofilaments using the spinning assembly; controlling the crystal structure through two-stage stretching involving wetting pre-orientation and dry heat main orientation; and stabilizing the fiber structure using a segmented temperature-controlled thermal relaxation process to obtain a finished monofilament product with flame-retardant properties. This invention achieves efficient and continuous production of flame-retardant monofilaments through the synergistic effect of plasma activation, gradient spinning, and staged orientation.
