Sludge rapid drying device with crushing device

Abstract

The invention provides a sludge rapid drying device with a crushing device, wherein the sludge rapid drying device includes a tank body; the interior of the tank body is separated into a crushing cavity and a drying cavity through a separating plate; a crushing device is arranged in the crushing cavity; an impurity discharge pipe is arranged on the side wall of the bottom of the crushing cavity; aspiral stirrer and an air-blast drying device are arranged in the drying cavity; the spiral stirrer is composed of a spiral stirring blade, a retaining side and a scraping plate; the air-blast dryingdevice is composed of a transmission box, a second motor, a gas intake pipe, a second rotating shaft and a jet plate; an electric heater is inlaid on the side wall of the drying cavity; a discharge pipe is arranged on the side wall of the bottom of the tank body; a jacket is arranged on the outer surface of the tank body; the side wall of the bottom of the jacket is provided with a dehumidification device. Agglomerated sludge is subjected to crushing treatment by the crushing device; the sludge is circulated and stirred by the spiral stirrer; hot air and the sludge make even contact by the air-blast drying device, so that the sludge is evenly dried.

Description

[0001] This application is a divisional application with application number 2016110394672, application date of November 21, 2016, and the title of the invention "a rapid drying equipment for sludge with a crushing device". technical field [0002] The invention relates to a sludge drying machine, in particular to a sludge rapid drying equipment with a crushing device. Background technique [0003] Sludge is rich in nutrients, which can not only increase soil nitrogen, phosphorus, and potassium nutrients, but also improve soil compaction and alkalization. As a developing country, my country is also a large agricultural country. Therefore, from the perspective of economy and resource utilization Considering that the land use of sludge is a way that is in line with my country's national conditions. The sludge dryer is a kind of stirring paddle installed inside the equipment, so that the wet sludge can fully contact with the heat carrier and the hot surface under the agitation of...

AI Technical Summary

Problems solved by technology

However, the structure of the traditional sludge dryer is unstable when the propeller blades are stirring the sludge, the force bearing of the stirring blades is uneven, the power consumption is large, and the contact surface of the sludge heated and dried is small, which may easily cause uneven drying of the sludge and affect Sludge Drying Efficiency
