5results about How to "Adjust particle size" patented technology

This application relates to a polyacrylamide spiral granulator, belonging to the field of granulators. It includes a feed cylinder, a motor, a spiral conveyor, a die plate, and a conveying cylinder. The conveying cylinder is horizontally positioned, and the feed cylinder is vertically positioned above it, with its lower end connected to the conveying cylinder. The spiral conveyor is disposed inside the conveying cylinder, and the motor is located on one side of the conveying cylinder and drives the spiral conveyor. The die plate includes a fixed plate and a rotating plate. The fixed plate has multiple discharge holes (first type), and the rotating plate has multiple discharge holes (second type). The rotating plate and the fixed plate rotate relative to each other. The conveying cylinder is equipped with a fixing component to fix the positions of both the rotating plate and the fixed plate. This application has the effect of allowing users to quickly adjust the particle size of the extruded polyacrylamide granules.

The utility model discloses a crusher for crushing asphalt reclaimed materials, and belongs to the technical field of crushers. The crusher comprises a machine frame and two crushing rollers, the two crushing rollers are both rotationally connected with the machine frame, one crushing roller is rotationally connected with the machine frame through a turnover frame, the turnover frame is rotationally connected with the machine frame, and an elastic mechanism is arranged between the turnover frame and the machine frame. When hard impurities with increased sizes enter the crusher, the movable crushing rollers can be pushed away under the action of interaction force due to the action of resistance, so that the turnover mechanism rotates in the direction of overcoming the elastic force of the elastic mechanism, the distance between the crushing rollers is increased, the impurities can pass through the space between the two crushing rollers, and the impurities are separated from the crushing rollers. In this way, when the crushing roller encounters hard and large-size impurities, the crushing roller can pass through the crushing roller to prevent the crusher from being damaged, and the equipment is protected.

The application discloses a CO-SCR catalyst, a preparation method and application thereof, and the CO-SCR catalyst comprises a cerium-based composite oxide carrier and a noble metal active component, and the noble metal active component is dispersed on the surface of the cerium-based composite oxide carrier by means of a surfactant. The CO-SCR catalyst utilizes the dispersion and loading of the noble metal assisted by the surfactant, so that the CO-SCR catalyst has higher metal dispersion and redox capacity. Meanwhile, the suitable pH value of the carrier surface is also beneficial to the adsorption of CO and NO, and the low-temperature catalytic activity and high-temperature stability of the catalyst are improved, and the CO-SCR catalyst has higher catalytic activity and nitrogen selectivity in the use temperature range of 250 DEG C to 400 DEG C.

The application discloses a low-GI rice flour production raw material crushing equipment and a crushing method thereof, and relates to the technical field of low-GI rice flour production. The equipment comprises a hopper which is a raw material feeding port of the equipment. A coarse powder machine is arranged at the bottom of the hopper and used for coarsely crushing the raw material. One end of the coarse powder machine is connected with a feeder. One end of the feeder is connected with a feeding air pipe. The other end of the feeder is connected with a crushing disc. The crushing disc is driven by airflow to finely crush the raw material by mutual collision. A screening device is connected to the crushing disc and used for screening the raw material which is finely crushed. The screening device can also send the raw material with relatively coarse particles which is screened out back to the crushing disc for secondary crushing. The feeder and the screening device are arranged to control the crushing efficiency and effect of the raw material. Meanwhile, the feeder and the screening device can be adjusted to adjust the particle size of the raw material after crushing.

This invention discloses an organofluorosilicone emulsion deepening agent, which is made from the following raw materials in parts by weight: 3-9 parts of hexamethylcyclotrisiloxane, 2-4 parts of trifluoropropylmethylcyclotrisiloxane, 1-3 parts of hexamethyldisiloxane, 3-9 parts of vinyldisiloxane, 1-3 parts of emulsifier, 0.1-0.6 parts of catalyst, and 2-6 parts of acrylate monomer. The organofluorosilicone monomer is prepared by ring-opening reaction of hexamethylcyclotrisiloxane, trifluoropropylmethylcyclotrisiloxane, and hexamethyldisiloxane under the action of trifluoromethanesulfonic acid catalyst. Then, the emulsifier is used to emulsify the monomer to obtain organofluorosilicone emulsion I. This invention has a simple preparation method, can reduce dye affinity, and inhibit dye migration. Furthermore, by changing the amount of emulsifier, the particle size of the emulsion can be adjusted, and emulsions of different particle sizes can be mixed together to form a film with different roughness, thus achieving a deepening effect.
