Quick sludge drying equipment with crushing device

Abstract

The invention provides quick sludge drying equipment with a crushing device. The quick sludge drying equipment comprises a tank; the internal of the tank is divided into a crushing cavity and a drying cavity through a separation plate; the crushing device is arranged in the crushing cavity; an impurity removing pipe is arranged on the side wall of the bottom of the crushing cavity; a spiral stirrer and an air blowing drying device are arranged in the drying cavity; the spiral stirrer consists of a spiral stirring blade, a stop edge and a scraping plate; the air blowing drying device consists of a transmission box, a second motor, an intake pipe, a second rotating shaft and an air spraying plate; an electric heater is embedded in the side wall of the drying cavity; a discharge pipe is arranged on the side wall of the bottom of the tank; a jacket is arranged on the outer surface of the tank; and a dehumidifying device is arranged on the side wall of the bottom of the jacket. The quick sludge drying equipment crushes caked sludge through the crushing device, achieves the purpose of circularly stirring the sludge through the spiral stirrer, facilitates uniform contact between hot air and the sludge through the air blowing drying device, and facilitates uniform drying of the sludge.

Description

technical field [0001] The invention relates to a sludge drying machine, in particular to a sludge rapid drying equipment with a crushing device. Background technique [0002] 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 the paddle, so as to achieve the purpose of drying. The sludge dryer is widely used in activated sludge, sewage sludge, petrochemical sludge, papermaking sludge, printing and dyeing sludge, tanning sludge, electroplating sl...

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
