A powder metallurgy drying equipment for the production of metal products

Abstract

The invention discloses a powder metallurgy drying equipment for metal product production, which belongs to the technical field of metal product production. A flexible drying belt is added in the drying cavity formed by the drying outer cylinder and the drying inner cylinder, and a plurality of drying belts are arranged on the flexible drying belt. In the storage tube loaded with metal powder, when drying, the flexible drying belt is rolled into the drying chamber, the hot air in the drying inner tube is evenly transferred to the flexible drying belt, and the metal powder in the storage tube is evenly heated, and the drying process is completed. During the rotation of the outer cylinder, the vibration body at the bottom of the storage cylinder makes the elastic drying bag vibrate up and down. The metal powder not only shakes during the centrifugal rotation, but also vibrates up and down with the elastic drying bag, which is beneficial to the large fluctuation of the metal powder. When drying After the completion, the flexible drying belt is pulled out, which can not only realize the ventilation and heat dissipation of the storage tube, shorten the cooling time of the metal powder, but also do not need to open the drying equipment to facilitate the export of the metal powder in the storage tube, saving energy and loss.

Description

technical field [0001] The invention relates to the technical field of biological test tube drying, and more specifically relates to a powder metallurgy drying equipment for metal product production. Background technique [0002] Powder metallurgy is an industrial technology for producing metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, forming and sintering to produce metal materials, composite materials and various types of products. [0003] At present, powder metallurgy technology has been widely used in transportation, machinery, electronics, aerospace, weapons, biology, new energy, information and nuclear industries, and has become one of the most dynamic branches of new material science. Powder metallurgy technology has a series of advantages such as significant energy saving, material saving, excellent performance, high product precision and good stability, and is very suitable for mass production.

Problems solved by technology

[0004] The traditional technology utilizes sending hot air to the drying equipment to dry the metal powder, while the existing equipment generally adopts drum drying. Even in the rotating drying equipment, the metal powder is easy to accumulate at the bottom of the drying equipment, and it is difficult to effectively dry the metal powder. In addition, when the drying is completed, if the drying equipment is directly opened to export the metal powder, it will cause heat loss to a certain extent, which is not conducive to the subsequent drying operation, and the temperature of the directly exported metal powder is too high. If the device is loaded, it is not easy for it to cool down quickly
