specific Embodiment
[0036] For the drying treatment of colloidal substances with drying parameters as follows:
[0037] Colloidal substances include organic matter and dispersed and suspended minerals, have a tendency to thermally bind, contain 80% water, and the product must be a dry powder containing 15% water. It adopts the working method of drying 120 tons per day and continuous operation for 24 hours and 7 days. In other words, for a dry amount of colloidal matter of 5 tons / hour, the evaporation of water will be 3824 kg / hour, and the theoretical calculation requires heat 3824 × 2257 kJ / kg = 8630768 kJ / H = 2397 kWh = about 360 kg of coal / Hour.
[0038] 1. Using existing industrial drying equipment:
[0039] Three cascade rotary dryers need to be installed and operated,
[0040] First stage 2200 mm diameter x 24000 mm length,
[0041] Second stage 1800 mm diameter x 20000 mm length,
[0042] Level 3 1500 mm diameter x 16000 mm length,
[0043] The hot gas requires 700 kg / h of coal, whic...

The invention discloses a combination drying device and a drying treatment method thereof. The combination drying device comprises a drum made of a heat conduction material, wherein the wall of the drum is sieve pore-like or screen-like, an external powered rotation mechanism is connected with the drum to drive the drum to rotate around the horizontal axis, the inside of the drum is provided with a metal ball receiving and outputting device, a plurality of metal balls are placed in the metal ball receiving and outputting device, the aperture of the sieve pore or screen is less than the diameter of the metal balls; and the inner wall of the drum is provided with a metal ball extracting device, the metal ball extracting device receives the metal balls, the metal balls output by the outputting device are lifted and then return to the inside of the metal ball receiving and outputting device, the heat supply output port of a metal ball heating system is installed in the metal ball receiving and outputting device, and a to-be-dried good inputting device is installed in the metal ball receiving and outputting device. By adopting the combination drying device, the heat transfer efficiency of the drying process can be extremely increased, the manufacturing cost can be saved and the energy consumption can be reduced; the device is easy to maintain and low in operating cost. The combination drying device is worth of popularizing and using in the preparation field of the industrial raw material dry powder.
Description
technical field [0001] The invention relates to the technical field of industrial material drying, in particular to a mixing drying device and a drying treatment method. Background technique [0002] In the field of industrial production and processing, many industrial materials require dry powder treatment. Such as cement, lime, gypsum, sand, gravel building materials; such as mineral fillers, colorants, plasticizers, coating additives; such as nitrogenous fertilizers, lime materials, humic acid fertilizers; food such as fruit and vegetable powder, grains and roots powder, meat and bone meal; medicines such as capsules and tablets, beauty products; such as fillers, dyes, minerals or vegetables; waste disposal such as garbage and sludge; etc. In these industries, the main steps to obtain dry powder include: ① dry grinding, ② fine water grinding, ③ mixing with additives or adjuvants, ④ mechanical dehydration, ⑤ drying. [0003] There are various technical means and methods ...
