Cold water is injected into the water storage tank, so that the temperature of the bent stirring rod can be reduced, high heat can be prevented from being generated when lotus root starch is stirred, and the quality of the lotus root starch is prevented from being influenced.

This utility model discloses a reaction vessel for preparing the chemical product 4-methyldiphenylamine, including a reaction tank. The upper part of the reaction tank has a support plate inside, and the lower center of the support plate has a protective cylinder. It also includes a mixing mechanism. The mixing mechanism includes a circular groove, a sphere, a rotating cylinder, a sealed bearing, a rotating shaft, a stirring rod, and an L-shaped support rod. The top wall of the support plate is rotatably connected to the L-shaped support rod, and the rotating cylinder is fixedly connected to the left side of the lower end of the L-shaped support rod. The outer wall of the upper end of the rotating cylinder is fixedly fitted with a sphere. The bottom wall of the protective cylinder has a circular groove, and the inner arc surface of the circular groove is slidably connected to the outer arc surface of the sphere. The outer surface of the rotating cylinder is rotatably connected to uniformly distributed rotating shafts through the sealed bearing. This reaction vessel for preparing 4-methyldiphenylamine, through the combination of the rotation of the stirring rod and the circumferential oscillation of the stirring assembly, achieves a wider mixing range, eliminates blind spots in edge mixing, and provides a better mixing effect.

The utility model relates to the technical field of mixing machine equipment, and provides a strong shovel blade structure of a mixing machine, which comprises a stirring shovel arranged in a mixing cavity of the mixing machine, a shovel blade is axially arranged on the outer wall of the stirring shovel, an upper cambered surface with the top inclined inwards is arranged at the top of the shovel blade, a lower cambered surface with the bottom inclined inwards is arranged at the bottom of the shovel blade, and the upper cambered surface and the lower cambered surface are arranged on the outer wall of the stirring shovel. One side, far away from the stirring shovel, of the shovel blade is provided with an outer cambered surface with the outer part inclined inwards, one side, close to the stirring shovel, of the shovel blade is provided with an inner cambered surface which is the same as the outer cambered surface in inclination direction, and a reverse cambered surface which is opposite to the outer cambered surface and the inner cambered surface in inclination direction is arranged between the outer cambered surface and the inner cambered surface on the side wall of the shovel blade. The stirring shovel overcomes the defects in the prior art and is reasonable in design and compact in structure, when the stirring shovel works in the mixing cavity of the mixer, the shovel blades turn over materials in the mixing cavity up and down and inside and outside to form staggered flowing, stirring is more uniform, the shovel blades are wide in stirring range, and the stirring efficiency is improved. The movement tracks of the shovel blades are not overlapped, and the stirring uniformity is greatly improved due to different stirring speeds.

The invention provides a novel low-carbon environment-friendly heat-insulation building material preparation device and a preparation method thereof, and relates to the technical field of building material processing. A forming part is arranged at the upper end of the bottom frame and comprises four sets of rail plates, and rotating rods are connected between the two sets of rail plates close to the left side of the bottom frame and between the two sets of rail plates close to the right side of the bottom frame. Materials are mixed and conveyed through a material supply piece, two sets of first motors are operated to enable a forming plate to be conveyed to the right side, a forming groove in the forming plate is located under a pressing plate, first hydraulic rods are extended to enable the pressing plate to press downwards, material forming is completed, and a second motor is operated to adjust the front-back position of a spray head; the waterproof and fireproof additive is sprayed to the surface of the formed material through the spray head, and the finished product is obtained through drying and curing, so that accurate mixing and forming of the raw materials and uniform adding of the additive are achieved, the whole production process is more efficient and accurate, and meanwhile the high-quality standard of the product is ensured.
