The invention discloses a rotary magnetron target and horizontal magnetron sputtering coating equipment. The rotary magnetron target comprises a target, a magnetic core and a magnet, wherein the magnetic core is arranged at the middle part of the target, at least one magnet is arranged at the periphery of the magnetic core, and one end facing the target, of the magnet, is conical. The horizontal magnetron sputtering coating equipment comprises a front pre-pumping chamber, a front rough-pumping chamber, a front fine-pumping chamber, a front buffering chamber, a coating chamber, a rear buffering chamber, a rear fine-pumping chamber, a rear rough-pumping chamber and a rear pre-pumping chamber which are sequentially connected, wherein one or more coating chambers are provided, and one rotary magnetron target is arranged in each coating chamber, and located above a workpiece. According to the rotary magnetron target, the tail end of the magnet is designed to be a tip, thus the distribution density of magnetic force lines on the surface of the target is enhanced, and the number of the sputtered target particles can be increased, and then the coating efficiency of the surface of the workpiece is increased. The rotary magnetron target is applied to the horizontal magnetron sputtering coating equipment, thus the coating efficiency of the workpiece can be effectively increased, and the production cycle of a whole process line is shortened, and then the production efficiency is increased.

The invention discloses a classification and purification device for liquefied gas, which belongs to the technical field of gas purification and comprises a purification tank. A raw material tank is arranged on one side of the purification tank, and a liquefaction tank is arranged on the other side of the purification tank. The raw material tank and the The temperature of the liquefaction tank is lowered by the cooling device, and the raw material tank and the purification tank and between the liquefaction tank and the purification tank are connected by the first connecting pipe. The device, the placed raw material tank and liquefaction tank can squeeze the supporting bellows, so that the extruded gas is transported to the inside of the communication cavity through the gas delivery hose, and the gas pushes the sealing plate to slide inside the storage groove and the limit groove. The sealing plate slides out of the limit groove under the push of the gas, and seals the gap between the cooling barrel, the raw material tank and the liquefaction tank, so that the cooling effect of liquid nitrogen is better, and the effect of liquefaction and purification of gas is improved. better.
