Embodiment Construction

[0012] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0013] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0014] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indic...

Abstract

The invention discloses powder screening equipment, and relates to the technical field of powder screening. With the powder screening equipment, powder is prevented from being affected by damp or polluted in the powder drying and screening process, the working efficiency of drying and screening the powder is improved, and the labor cost is reduced. The powder screening equipment comprises a drying device, rotary screen cloth, a feeding pipe and a discharging pipe arranged on the drying device. The drying device is provided with a drying space, and the rotary screen cloth is located in the drying space. The drying space is divided by the rotary screen cloth into a screen cloth feeding area and a screen cloth discharging area. The feeding pipe is arranged on the rotary screen cloth and communicates with the feeding area of the screen cloth. A feeding port of the feeding pipe is located outside the drying space. The discharging pipe is communicated with a discharging area of the screen cloth. The powder screening equipment is used for screening and drying powder.

Description

technical field [0001] The invention relates to the technical field of powder screening, in particular to a powder screening equipment. Background technique [0002] The metal powder used in the existing laser additive forming technology has a large specific surface area and strong adsorption force, and it is easy to be damp and form agglomerates during storage and transportation. In addition, in the recovered powder after use, there are particles that are not completely fused and sintered together, which are beyond the particle size range of the powder. For the convenience of description, "agglomeration" is defined below as "particles that are not completely fused but sintered together beyond the particle size range of the powder". Therefore, in order to improve the quality of the powder used, it is necessary to dry and sieve the powder, evaporate the moisture absorbed by the powder, and sieve out the agglomeration and accumulation in the powder. [0003] In the prior art...
