Municipal-sludge treating equipment

Abstract

The invention discloses municipal-sludge treating equipment. The municipal-sludge treating equipment comprises a body and a blanking channel arranged in the body, wherein the body is internally provided with a first transmission cavity positioned at the left side of the blanking channel; a feeding cavity extending rightwards and opening leftwards is arranged at the right side of the blanking channel; the blanking channel is internally and rotatably provided with a first rotating shaft extending leftwards and rightwards; the first rotating shaft is provided with an extruding disc in a manner ofsliding leftwards and rightwards; a first spring surrounding the outer surface of the first rotating shaft is arranged between the left end surface of the extruding disc and the left end wall of theblanking channel; the first rotating shaft extends rightwards to enter a feeding cavity. The municipal-sludge treating equipment disclosed by the invention has the beneficial effects that the structure is simple, the operation is convenient, mechanical extrusion is firstly utilized to remove water in sludge, then the physical property that lime can generate heat when meeting water is utilized to remove residual water in the sludge, and because of secondary dewatering, the dewatering rate is higher; because of the chemical action of the lime, the acidity and the alkalinity of the sludge can bechanged, so that the treated sludge is more beneficial to secondary utilization or landfill, and the practical performance of the device is improved.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a treatment method for municipal sludge. Background technique [0002] With the acceleration of urbanization and the gradual increase of urban residents, a large amount of domestic sewage sludge will be produced in this process. In the process of urban sludge treatment, there has always been a relatively difficult technical problem, which is the dehydration rate of traditional sludge dewatering equipment. Low, and the degree of automation is not high, resulting in the treated sludge can not meet the secondary utilization or landfill standards, this device effectively solves this problem. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a treatment method for municipal sludge, which can solve the above-mentioned problems in the prior art. [0004] The present invention is achieved through the following technical...
