Embodiment

[0033] Such as Figure 1 to Figure 6 As shown, a tube-and-tube powder heat exchanger includes a feed box 2 and a heat exchange box 5, the feed box 2 is arranged at the upper end of the heat exchange box 5, and the lower end of the heat exchange box 5 is provided with a discharge hopper 9 There is a vibration motor 10 outside the discharge hopper 9. After the vibration motor 10 is started, the heat exchange box 5 can be properly vibrated to facilitate the sufficient heat exchange of materials in the heat exchange box 5 and protect the heat exchange tube 3 at the same time. Function (to prevent the heat exchange tube 3 from being in contact with high-temperature materials for too long, which will reduce the service life of the heat exchange tube 3 due to damage); the vibration motor 10 can conveniently control the heat exchange time of the material in the heat exchange box 5, and then control the discharge temperature.

Abstract

The invention discloses a tube nest type micro-powder heat exchanger comprising a feed box and a heat exchange box. The feed box is arranged at the upper end of the heat exchange box, a discharge hopper is arranged at the lower end of the heat exchange box, and a vibrating motor is arranged outside the discharge hopper. Heat exchange tubes are arrayed in the heat exchange box, a water inlet box cover communicated with the heat exchange tubes is arranged outside the heat exchange box, and a water outlet box cover communicated with the heat exchange tubes is arranged outside the heat exchange box. The tube nest type micro-powder heat exchanger has the advantages of simple structure, convenience in manufacturing, no accessory devices, low device cost, non-breakable grain crystals, low energy consumption, small occupation space and the like. Materials generally go down among the heat exchange tubes in the heat exchange box, the grain crystals are less breakable, and product quality is effectively improved. Only the vibrating motor in the heat exchanger consumes energy, water for heat exchange is recycled, no dust and waste gas is discharged, energy saving and emission reduction effects are remarkable. Besides, the heat exchanger practically without motion parts during operation is good in stability and low in maintenance and can produce great economic and social benefits for users.

Description

technical field [0001] The invention relates to a heat exchange device for powder and granular materials, in particular to a tube-and-tube powder heat exchanger, which is mainly used in chemical industry, building materials, metallurgy and other industries. Background technique [0002] In the chemical industry, building materials, metallurgy and other industries, a large amount of powdery and granular materials are often produced at high temperatures, and these materials need to be cooled to a certain temperature at a faster rate before packaging, so that they can be packaged, stored and transported normally. [0003] In today's large-scale and high-speed production, natural cooling in the past can no longer meet the needs of production. Therefore, heat exchangers suitable for powder cooling have a broad market space. [0004] Generally, the devices for cooling powders and granules include rotary type and fluidized bed type. Rotary heat exchangers have disadvantages such ...
