Description

Technical Field

[0001] The utility model relates to the field of nozzle technology, in particular to a powder fluid nozzle for the lithium battery industry. Background Art

[0002] The positive and negative electrode powder fluids in the lithium battery industry usually flow out through pipes to nozzles, with the characteristics of high temperature, high pressure and high speed. The high-speed and violent impact of the fluid will cause wear of the nozzle mouth, the metal of the nozzle mouth will slowly fall off, and the internal flow hole will become larger or change in shape. In this case, the flow rate increases and the pressure decreases accordingly, which will affect the shape of the spray and the spray particles.

[0003] When powder fluid pressure, flow rate, and operating conditions are similar, there are currently two common methods for extending nozzle life: heat-treating and quenching metal nozzles to increase their hardness and improve wear resistance; and using ceramic nozzles. The first type of metal nozzle typically achieves a heat-treated hardness of only 50-60 HRC. Higher hardness leads to cracking, significantly reducing plasticity and strength. Ceramic nozzles typically have a hardness of 7-9 on the Mohs hardness scale (approximately 25-33 HRC). The hardness of these two nozzles determines their wear resistance, resulting in insufficient performance in actual operating conditions and requiring frequent replacement.

[0004] As can be seen from this, the existing nozzle materials have low hardness, poor wear resistance, and are easily worn. High-hardness materials have low plasticity and strength, are prone to cracking, are difficult to form, and are difficult to install. The mounting threads are easily damaged and fail. Therefore, it is necessary to develop a solution to address the above issues. Utility Model Content

[0005] In view of this, the present invention aims to address the shortcomings of the existing technology, and its main purpose is to provide a powder fluid nozzle for the lithium battery industry, which can effectively solve the problems of poor wear resistance and short practical life of the existing nozzles.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A powder fluid nozzle for the lithium battery industry includes a main body and a wear-resistant ring; a fluid channel is provided in the main body, a fluid inlet is provided at the input end of the main body, the fluid inlet is connected to one end of the fluid channel, and a mounting hole is provided at the output end of the main body; the wear-resistant ring is made of cemented carbide, is embedded in the mounting hole and fixed, and a fluid outlet is formed on the wear-resistant ring, which is connected to the other end of the fluid channel.

[0008] Preferably, the main body is made of 416 stainless steel or 630 stainless steel, and the hardness of the main body after heat treatment is 50-60HRC.

[0009] Preferably, an external thread is formed on the outer wall of the input end of the main body.

[0010] Preferably, the output end profile of the main body is in the shape of a nut.

[0011] Preferably, the wear-resistant ring is made by sintering powder and has a hardness of 70-90HRC.

[0013] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:
