Dry sludge crushing device

Abstract

The invention discloses a dry sludge crushing device. The dry sludge crushing device is characterized by comprising a shell, a supplying unit, a feeding unit, a crushing unit, a blockage clearing unit and a discharging unit, wherein the supplying unit supplies dry sludge to the feeding unit; the feeding unit is installed at the upper end of the shell; the feeding unit transfers the dry sludge to the crushing unit arranged below the feeding unit; the crushing unit and the blockage clearing unit are located in the shell; the crushing unit crushes the dry sludge; the blockage clearing unit is arranged below the crushing unit; the discharging unit is arranged at the bottom end of the shell; and the crushed dry sludge is discharged from the discharging unit. According to the dry sludge crushing device, by integrating the feeding unit, the crushing unit, the blockage clearing unit and the like, the remarkable problems that a crusher is unsmooth in feeding and prone to blockage during discharging are solved, and high efficiency, environment friendliness, energy conservation and safety in the sludge crushing process are achieved.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment, and in particular relates to a dry sludge crushing device. Background technique [0002] In the conventional sludge incineration process, the sludge is directly poured into the silo, and then sent to the incinerator through the conveying equipment. The sludge formed in large pieces is often blocked, which makes the transportation efficiency low, so it is often required to be coarsely crushed. The crusher is directly connected to the bottom of the silo, which may easily cause excessive load fluctuations. In order to prevent the crusher from being overloaded and stop running, it is necessary to balance the feeding speed; adding a conveyor between the silo and the crusher to achieve uniform feeding has the disadvantages of large equipment footprint and high energy consumption. [0003] Secondly, when the sludge is fed, the hardness is different, and the crushing effect is uneven. ...
