The invention discloses a method for preparing a wear-resistant ceramic liner by an active brazing method, which relates to a method for preparing a wear-resistant ceramic liner. The invention solves the problems of low bonding strength, easy falling off of ceramics and easy aging of rubber materials in the existing adhesive and wear-resistant ceramic rubber liners, and the problems that the existing wear-resistant ceramic liners connected by bolts are easy to break and have short anti-wear life. The method of the invention is as follows: 1. preparing active metal paste solder; 2. surface-treating ceramic blocks and steel plates; 3. preparing welding assembly parts; The wear-resistant ceramic liner of the present invention cancels the rubber layer, improves the bonding strength, wear resistance and high-temperature service life, and the shear strength of the brazing joint reaches 191MPa; the low cooling rate reduces the residual stress of the liner, and the liner is not easy Breakage, extended service life. The obtained liner can be used for coal conveying and ash discharge systems in thermal power plants, as well as anti-wear liners in material conveying and batching systems in metallurgical iron and steel industries, such as silos and hoppers.

The invention discloses an oil fume guide type range hood which comprises a draught fan hood and a fume collecting hood. A draught fan is arranged inside the draught fan hood. A fume baffle is arranged on the upper portion of the front side of the fume collecting hood. The oil fume guide type range hood is characterized in that a fume guide plate is arranged on the rear side of the fume baffle; the space between the fume guide plate and the fume baffle forms a fume guide cavity; the space between the fume guide plate and the fume collecting hood forms a fume collecting cavity; further, clearances are reserved between at least two lateral sides of the fume guide plate and the position, corresponding to the fume collecting hood, of the shell, so that the fume guide cavity communicates with the fume collecting cavity; and the range hood further comprises an air blowing guide device which comprises air blowing ports, the air blowing ports are used for blowing out airflow which is close to the fume guide plate and flows obliquely upwards and towards the middle, and the air blowing ports are formed in the two sides of the front portion of the fume collecting hood correspondingly and close to the bottom of the fume collecting hood.

The invention relates to the field of 5G signal radio frequency technology, and discloses a 5G radio frequency signal stability detection device, in which an auxiliary rod is movably connected to the inner side of the driving part. The 5G radio frequency signal stability detection device interacts with the signal receiver through the stable seat when the screw rotates counterclockwise, and the signal receiver is subjected to a resisting force to form an upward and downward movement trend. The information is received, and the signal antenna is unfolded by the linkage of the signal receiver to increase the speed of receiving signals. The upper end of the main shaft is subjected to strong vibration force to push the unfolding part to run. The force is diffused to both ends, and the extended parts that have been attenuated during the signal propagation process are re-deployed, which achieves the effect of information stability detection, and also provides convenience for high-speed operation, which is more conducive to the transmission of network signals and ensures the commercial use of 5G networks. Maximize value.

The invention provides a light-emitting diode epitaxy structure with a hole energy adjustment layer, and relates to a semiconductor device which has at least one potential jump barrier or surface barrier and is especially suitable for light emission. A P-type semiconductor material hole energy adjustment layer with a low barrier layer is inserted into a P-type semiconductor material transport layer of the LED epitaxy structure; the material is Al<x1>In<y1>Ga<1-x1-y1>N; in the formula, x1 is smaller than or equal to 1 and greater than or equal to 0; y1 is smaller than or equal to 1 and greater than or equal to 0; 1-x1-y1 is greater than or equal to 0; the thickness is 1-300nm; the lattice constant of the hole energy adjustment layer is greater than those of a P-type semiconductor material transport layer I and a P-type semiconductor material transport layer II; and the forbidden bandwidth is smaller than those of the P-type semiconductor material transport layer I and the P-type semiconductor material transport layer II. The hole energy is increased by a polarization electric field to improve the hole injection efficiency; a hole barrier is not increased; and the defects of low hole injection efficiency and low internal quantum efficiency in the prior art are overcome.
