Problems solved by technology

The advantages of NdFeB are high cost performance and good mechanical properties; the disadvantages are low working temperature, poor temperature characteristics, and easy to powder corrosion and easy to be oxidized
At present, the more commonly used material barrel is generally composed of a cylindrical barrel body. The material barrel is provided with a material connection port that matches the discharge port of the jet mill. Although it can be more convenient for material connection of NdFeB, due NdFeB itself is very easy to oxidize, and this type of barrel cannot isolate the air while receiving the material, resulting in a great reduction in the quality of NdFeB
[0005] The root cause of the above problems lies in the lack of a barrel in the prior art that is specifically designed for use in the process of joining NdFeB materials, and the lack of a barrel that can still have a better seal during rapid and multiple disassembly and assembly processes.

Embodiment 1

[0115] Such as figure 1 As shown, this embodiment provides a pneumatic sealing gasket. It includes an outer rubber ring 110 and an inner rubber ring 120 arranged concentrically, and the outer rubber ring 110 and the inner rubber ring 120 pass through at least two connecting pipes 130 uniformly distributed along the circumferential direction (in this embodiment, the number of connecting pipes 130 is 8 1) connected as a whole; the inner hollow of the outer rubber ring 110 is configured as an annular air storage chamber 221, and the inner hollow of the inner rubber ring 120 is configured as an annular gas collection chamber 223, and the middle part of any connecting pipe 130 is configured for The gas channel 222 communicates with the gas storage chamber 221 and the gas collection chamber 223 .

[0116] Wherein, the capacity of the gas storage chamber 221 can be 2 to 5 times the capacity of the gas collection chamber 223, the side wall thickness of the gas storage chamber 221 can...

Embodiment 2

[0118] Such as figure 2 As shown, this embodiment provides a sealing gasket for NdFeB storage barrels, which is different from Embodiment 1 in that: the outer rubber ring 110 and the connecting pipe 130 are constructed with a braided layer 210.

[0119] In this embodiment, the braided layer 210 is formed by interlacing warp yarns and weft yarns, and the warp yarns and weft yarns are all made of blended yarns made of nylon fibers and metal fibers, and all the warp yarns and weft yarns of the braided layer 210 are spirally wrapped around the outer rubber The appearance of the ring 110 and the connecting pipe 130.

[0120] In this embodiment, the nylon fiber in the warp yarn accounts for about 85%, and the metal fiber accounts for about 15%, so that the warp yarn has better elasticity and toughness; the nylon fiber in the weft yarn accounts for about 80%, and the metal fiber accounts for about 20%, so that Make the warp have better elasticity and strength. In addition, the de...

Embodiment 3

[0122] This embodiment provides a sealing ring for the airtight connection of pipe fittings. The difference from Embodiment 2 is that the material of the outer rubber ring 110 is composed of natural rubber, butadiene rubber, nitrile rubber, Titanium dioxide, carbon fiber, nano-zinc oxide, paraffin-based rubber softening oil, plasticizer, stearic acid, composition;

[0123] The material of the inner rubber ring 120 is composed of natural rubber, butadiene rubber, active silicon powder, carbon black, sulfur, anti-aging agent, accelerator, zinc oxide, magnesium oxide, stearic acid, and aromatic oil.

[0124] In this embodiment, the parts by weight of each component in the outer rubber ring 110 can be any one of the following ranges: 55-65 parts of natural rubber, 15-25 parts of butadiene rubber, 5-10 parts of nitrile rubber, titanium dioxide 1.5-2.5 parts, 1-2 parts of carbon fiber, 1-1.5 parts of nano zinc oxide, 9-11 parts of paraffin-based rubber softening oil, 6-7 parts of pl...

Abstract

The invention relates to the technical field of NdFeB production equipment, in particular to an interface structure for an NdFeB storage tank. It includes a barrel mouth arranged on the barrel body, the opening end of the barrel mouth is constructed with a stepped connection part, and the outer side of the connection part is threaded with a fastening ring; the connection part is provided with a gap in the axial direction, and the fastening ring is placed There is a ejector rod in the gap; the internal structure of the fastening ring has an accommodation chamber for placing the ejector rod, the inner wall of the fastening ring is provided with a telescopic opening connected with the accommodation chamber, and the ejector rod is telescopically constructed in the accommodation chamber from the telescopic opening; The side wall of the cavity opposite to the expansion port is provided with a top rail in the circumferential direction. The gap between the top rail and the expansion port gradually becomes smaller in the direction of rotation of the fastening ring. The top rail is used to follow the rotation of the fastening ring to change the diameter of the ejector rod. up position. Through the present invention, the NdFeB storage barrel can be preferably fixedly connected to the corresponding discharge port.

Description

technical field [0001] The invention relates to the technical field of NdFeB production equipment, in particular to an interface structure for an NdFeB storage barrel. Background technique [0002] NdFeB magnetic material, as the latest result of the development of rare earth permanent magnet materials, is called "Magnetic King" because of its excellent magnetic properties. NdFeB magnetic material is an alloy of praseodymium neodymium metal, boron iron, etc., also known as magnetic steel. NdFeB has extremely high magnetic energy product, coercive force and energy density. It has been widely used in modern industry and electronic technology, making instruments and meters, electroacoustic motors, magnetic separation and magnetization equipment miniaturized, lightweight, Thinning is possible. [0003] NdFeB contains a large amount of rare earth elements neodymium, iron and boron, and its characteristics are hard and brittle. The advantages of NdFeB are high cost performance ...
