Sludge dryer for environmental governance riverway restoration

Abstract

The invention discloses a sludge dryer for environmental governance riverway remediation, and the sludge dryer comprises a fixed sludge drying mechanism and a limit driving motor mechanism, wherein the input end of the fixed sludge drying mechanism is connected with the limit driving motor mechanism. According to the drying machine, when the folded blades rotate and exchange heat with sludge, thedrying heating lamp tube and the pumping pump can be synchronously started, the interior of the drying working cavity is pumped through the long pumping pipe to be in a micro-negative-pressure state,meanwhile, water is heated to become steam, the steam is separated from the sludge and then discharged, and finally sludge drying is achieved; moreover, a current in the annular electromagnet can be switched on during drying, and the annular electromagnet is used for firmly adsorbing the annular iron ring on the outer side of the annular electromagnet, so that the working stability of the folded blades is improved, the folded blades are prevented from generating relative displacement to influence the drying effect when being impacted by sludge, and the mounting stability is also improved; andthe current in the annular electromagnet can be immediately cut off after the work is finished or during maintenance, so the positioning sleeve can be conveniently taken down from the long rotating rod.

Description

technical field [0001] The invention relates to the technical field of equipment related to environmental treatment, in particular to a sludge dryer for environmental treatment and river restoration. Background technique [0002] Sludge biological drying is to use the microorganisms in the sludge to use its own organic matter as raw material, and use the oxygen in the air to remove the surface water and bound water in the sludge through the heat generated during its metabolism to improve its low level. Calorific value; microorganisms decompose various metabolites of organic matter through biochemical reactions to meet their own metabolism and growth needs, and gradually mineralize organic matter. The sludge dryer is a kind of equipment specially used to separate the water in the sludge. It realizes the sludge drying by indirect heating and low-speed stirring. The existing indirect sludge drying equipment is pushed by a single-channel rotary screw, which includes a long cyli...

Problems solved by technology

[0003] In the existing sludge dryer, the relative displacement of the propeller blades is prone to occur when rotating and exchanging heat, which affects its working efficiency. The blades are prone to float or unbalance when stirring the sludge, which affects its service life and the driving motor works stably. Poor sex
