Abstract

The invention discloses an air flue air distribution structure of a heat pump drying machine. The air flue air distribution structure comprises a shell, a drying chamber and a heat pump main engine. The shell is formed by packaging an insulation board. A lower conveying net belt and an upper conveying net belt are arranged in the drying chamber. First space is formed below the lower conveying net belt. Second space is formed between the upper conveying net belt and the lower conveying net belt. Third space is formed above the upper conveying net belt. A first air opening is formed in the top of the drying chamber. Second air openings, third air openings and fourth air openings are formed in the sided face of the drying chamber from bottom to top in sequence. An inner circulation air flue and an outer circulation air flue can be formed, the air flues are arranged reasonably and inlaid in the drying chamber, closed circulation is achieved, full heat preservation is achieved, heat is prevented from being lost, and the cost for manufacturing an outer independent air flue is omitted. In addition, dry air can be fully saturated to take away more water, the drying efficiency is improved, and the problem that sludge on the upper conveying net belt is dried unevenly is solved.

Description

technical field [0001] The invention relates to the technology in the field of dryers, in particular to an air distribution structure for an air duct of a heat pump dryer. Background technique [0002] The Ministry of Housing and Urban-Rural Development predicts that the amount of sludge that needs to be safely treated and disposed of in cities and towns in my country will reach 31.43 million tons in 2015 according to the target requirements for the treatment rate of sewage discharge during the "Twelfth Five-Year Plan" period. In addition, the rivers and lakes adjacent to cities in my country have been seriously polluted, and the sediment containing high concentrations of heavy metals and toxic organic substances urgently needs to be excavated, dredged and treated. [0003] Heat pump drying is a recognized green drying technology. However, at present, heat pump drying equipment needs to manufacture an external separate air duct, which increases the cost, increases the heat l...
