Embodiment Construction

[0031] Such as Figure 1 to Figure 9 As shown, for existing defects, the subject of protection of the present invention is as follows:

[0032] The development is a continuous drying system for the production of vanadium-free rare earth-based titanium and tungsten powder. The use of the bowl enables the materials in the sagger to heat up and cool down at the fastest speed, improving the roasting efficiency. At the same time, the roasting mode is segmented and controlled in different temperature segments to achieve a multi-gradient temperature control mode and consider energy saving. The problem of gradient utilization of thermal energy.

[0033] At the same time, the saggers are grouped, and through the joint action of the transmission system, multiple batches can be carried out at the same time, the drying efficiency can be improved, and continuous and circular production can be realized.

[0034] Based on the above description, the structural part includes a continuous dry...

Abstract

The invention provides a continuous drying system for production of vanadium-free rare earth-based titanium tungsten powder. The system comprises a plurality of groups of drying furnaces, chain type conveying machines, roller type conveying machines, an automatic loading machine and an automatic unloading machine, wherein the plurality of groups of drying furnaces are arranged side by side; each drying furnace comprises a plurality of sections of temperature control boxes in a connection manner to form a calcination channel; every two temperature control boxes are in one group and all the temperature control boxes are divided into eight sections; the temperature sub-gradients of eight temperature control sections are reduced in sequence from the front to back; a negative-pressure exhaust fan is arranged at the tops of the temperature control boxes in the eighth temperature section; the roller type conveying machines are positioned at the inlet ends and the outlet ends of the drying furnaces and are arranged in a crossed manner with the chain type conveying machines at the outer ends of the roller type conveying machines; sensors are arranged on the connection parts of the roller type conveying machines and the chain type conveying machines; the automatic loading machine and the automatic unloading machine are arranged at the appropriate positions on the chain type conveying machines. The continuous drying system can be used for simulating the environment in an electric heating furnace by taking measures of setting the temperature in a subsection manner, adjusting the running speed and the like, so that the aim of temperature control is realized.

Description

technical field [0001] The invention relates to a drying production line system capable of circulation and continuous production. Background technique [0002] The current intermediate process of granular vanadium-free rare earth-based titanium-tungsten powder uses an electric heating furnace for batch drying, that is, the material is placed in the electric furnace, and the roasting temperature is set at a temperature range of 400 to 600 ° C, and the roasting time is set at 2 to 4 hours. In this process, the material needs to be placed in a closed electric furnace for roasting. The sintering time is long, and it needs to go through the heating and cooling stages, and it needs to be fed in batches, so the time is longer and the efficiency is lower. Low. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a continuous drying system for producing vanadium-free rare earth-based titanium-tungsten powder, which ...
