The automatic feeding device is designed according to existing requirements, synchronous feeding of various food materials can be completed at a time, the food material proportion can be adjusted in real time according to the requirements, rotating airflow can be generated while loading is conducted, rapid discharging of the food materials is assisted, and the discharging efficiency can be improved.

This invention discloses a phosphorus slag-based cementitious material, its preparation method, and its application, specifically relating to the field of cementitious materials technology. The cementitious material, by weight, comprises the following components: 60-90 parts phosphorus slag powder; 5-25 parts fly ash; 5-15 parts activator; 0.25-1.5 parts early-strength agent; and 0.2-0.5 parts water-reducing agent; wherein the specific surface area of ​​the phosphorus slag powder is 400-550 m². 2 / kg, particle size (D) 90 The particle size is 20-40 μm; the early-strength agent is selected from at least one of iron salts and aluminum salts. This invention uses phosphorus slag micro-powder with a specific specific surface area as the main substrate, with a high dosage, combined with fly ash, activator, early-strength agent, and water-reducing agent to obtain phosphorus slag-based cementitious materials. By optimizing the physical properties of the phosphorus slag micro-powder and constructing a suitable composite activator-early-strength system, the 28-day compressive strength of the cementitious material reaches over 61.0 MPa, achieving a balance between "high phosphorus slag content" and "high strength".

A stirring device arranged on an aluminum foil rolling oil drum comprises a stirring pipe, one end of the stirring pipe is arranged in the oil drum, and stirring blades are arranged on the stirring pipe arranged in the oil drum. The other end of the stirring pipe is exposed out of the oil drum and is provided with an additive injection port; a stirring motor is arranged on one side of the stirring pipe exposed out of the oil drum, and is connected with the stirring pipe through a transmission part. The additive injection port is used for putting an additive into the oil drum and sampling a mixed solution in the oil drum, so that the additive is injected while stirring, the stirring uniformity of the mixed solution is improved, and the mixed solution in the oil drum can be conveniently sampled. When the stirring pipe does not rotate, the stirring blades vertically fall into the connecting grooves of the stirring pipe due to gravity, and when the stirring pipe rotates, the stirring blades extend outwards along with the rotational inertia of the stirring pipe; therefore, the stirring pipe can extend into the oil drum through the port of the oil drum and can stir the mixed liquid in the oil drum.

The invention discloses an environment-friendly long-acting antifouling paint and a preparation method thereof, and belongs to the technical field of paint materials and antifouling. The environment-friendly long-acting antifouling paint comprises the following components in parts by weight: 30-50 parts of a component A, 25-45 parts of a component B, 8-25 parts of a functional body, 1-5 parts of color paste and 0.3-3 parts of an auxiliary agent, the component A is an aliphatic isocyanate prepolymer which is prepared from aliphatic isocyanate and castor oil through a reaction, and the specific preparation raw materials comprise the following components in parts by weight: 20-40 parts of aliphatic isocyanate and 10-20 parts of castor oil; the component B is polyaspartic acid ester, and the molecular weight of the polyaspartic acid ester is 800-1500 g / mol; the castor oil has good reaction activity with aliphatic isocyanate, can significantly improve the flexibility of a prepolymer (polyurea precursor) and the cohesiveness with a base material, and can optimize the compatibility of the polyurea precursor with polyaspartic acid ester with the molecular weight of 800-1500 g / mol, thereby improving the mechanical stability and weather resistance of the whole polyurea paint coating. The technical problem that an existing coating material cannot give consideration to synergistic improvement of environmental protection property and mechanical property is solved.

This disclosure relates to the technical field of equipment for grinding wheel production. One embodiment of this disclosure provides a feeding device for grinding wheel production, comprising: an equipment frame, a first cylinder, a second cylinder, and a pair of pusher plates. The first cylinder and the second cylinder are respectively mounted on the two side surfaces of the equipment frame. The pusher plates are located at the output ends of the first cylinder and the second cylinder. A top frame is fixed to the top of the equipment frame. A leveling component is mounted on the top frame. Both a low-level material tank and a high-level material tank are mounted on the equipment frame and fixed to a support. A conveying pipe is provided at the bottom of both the low-level and high-level material tanks. A spiral pusher is installed inside the conveying pipe, and the spiral pusher is rotated by a motor. A discharge pipe is provided at the bottom of the conveying pipe. This technical solution solves the technical problem that existing grinding wheel production feeding machines generally use a single feeding mechanism and rely solely on high-quality materials for production, a traditional model that brings many problems that urgently need to be addressed.
