The utility model provides tapping equipment for valve accessory production. The tapping equipment for valve accessory production comprises a base and a supporting plate fixedly installed on the top of the base. The electric guide rail is assembled on the supporting plate; the hydraulic cylinder is mounted on the electric guide rail, and a tapping assembly is assembled on the hydraulic cylinder; the circular placing plate is arranged above the base; the cleaning mechanism is arranged on the base and is used for cleaning scrap iron on the circular placing plate; and the rotating mechanism is arranged on the base and the circular placing plate and is used for driving the circular placing plate to rotate. The tapping equipment for valve accessory production has the advantages that scrap iron on the containing plate can be automatically cleaned, and then the machining efficiency can be improved.

The invention relates to a preparation system and method of a nutrient nano-emulsion. The preparation system of the nutrient nano-emulsion comprises an ingredient homogenizing tank, a storage tank, a stirring device, a vacuum pipeline, a negative pressure pipeline and a nitrogen pipeline, the ingredient homogenizing tank is provided with a gas inlet suitable for being connected with a nitrogen pipeline so as to introduce nitrogen into the ingredient homogenizing tank, and a feeding hole suitable for putting an original material into the ingredient homogenizing tank; the stirring end of the stirring device extends into the cavity of the ingredient homogenizing tank; a discharge port is further formed in the batching and homogenizing tank, the discharge port is connected with an inlet of the storage tank through a negative pressure pipeline, and materials are suitable for flowing into the storage tank through the negative pressure pipeline; more than two ball valves are arranged on the negative pressure pipeline; one end of the vacuum pipeline is communicated with the interior of the cavity of the storage tank, and the vacuum pump is suitable for pumping air in the storage tank and the negative pressure pipeline through the vacuum pipeline. Based on the physical preparation principle, no organic solvent is used in the preparation process, and no pollutant is discharged.

This invention relates to the field of vacuum material conveying technology and discloses a vacuum material conveying device for continuous caramel production, comprising: an inner tube, an outer tube installed on the outer wall of the inner tube, and a cavity in the middle of the inner and outer tubes; further comprising: multiple cooling plates, the multiple cooling plates being symmetrically and equidistantly attached to the outer wall of the inner tube; a pushing part and a driving part are installed inside the cavity, the driving part being used to drive the pushing part to operate; two through holes are symmetrically opened on the inner wall of the inner tube; and a sealed chamber one and a sealed chamber two are respectively installed on the inner wall of the outer tube at positions corresponding to the two through holes; by setting up the cooling plates, the pushing part, and the driving part in cooperation, automatic coagulation and peeling of caramel can be achieved, which can replace manual scraping and high-pressure water washing cleaning methods, cleaning thoroughly without residue, and will not scratch the inner wall of the inner tube, maintaining the smoothness of the tube wall, effectively avoiding the problem of subsequent caramel adhesion and blockage caused by tube wall damage.

The utility model discloses a chicken feed granulator, which relates to the technical field of chicken feed granulating equipment, and has the technical key points that the chicken feed granulator comprises a granulator body, and the granulator body comprises a discharging assembly and a placing assembly; wherein the placing assembly comprises a limiting assembly and a limiting block, the limiting block is movably sleeved with the granulator body, and a threaded rod is fixed to the limiting block. The device has the technical effects that the placement block, the first connecting block and the threaded rod are arranged, and the rotating block is rotated, so that the threaded rod drives the placement block to move through the first connecting block, and a second connecting block moves along the vertical rod to limit the placement block; and then, chicken feed particles prepared by the granulator body can be discharged into the charging basin nearby through the discharging port block, so that the aim of discharging the chicken feed particles into the charging basin nearby and preventing the chicken feed particles from splashing on the ground is achieved through the design.

The invention belongs to the technical field of polyurethane, and discloses a washable weather-resistant flame-retardant waterborne polyurethane finishing agent as well as a preparation method and application thereof. The preparation method comprises the following steps: adding functional additives (modified silicon carbide, a flame retardant, a free radical scavenger, epoxy resin and a chain extender) into a polyurethane prepolymer for reaction; then adding aliphatic diamine to carry out an end capping reaction, adding water to carry out phase inversion, and then adding a polyacrylate emulsion and a plasticizer to carry out emulsification. Through the synergistic interaction of the epoxy resin, the silane coupling agent modified silicon carbide and the polyacrylate, the flame-retardant waterborne polyurethane is endowed with excellent washing resistance.
