Sludge feeding machine

Abstract

The invention discloses a sludge feeding machine, which comprises a machine body and at least two stirring and feeding shafts arranged in the machine body; bearings are arranged at the coordinated positions of the two ends of the stirring and feeding shafts and the machine body; bearing seats matched with the bearings of the stirring and feeding shafts are arranged at the corresponding positions of the machine body; each stirring and feeding shaft is provided with a speed reducer for driving the feeding shaft, a driving motor and a frequency converter for controlling the driving motor; the bearing seat comprises a seat body for mounting the bearing and a seat cover arranged outside the seat body; the outer side of the seat body and the seat cover form a closed cavity; and the closed cavity is provided with a liquid injection hole and a closeable liquid outlet. The driving speed reducer, the driving motor and the frequency converter are arranged on each stirring and feeding shaft, and each shaft forms a whole, so that transmission devices such as chains and chain wheels in the transmission process are eliminated, the power transmission part is simplified, and the sludge feeding machine is simple in structural design and convenient to maintain; the two driving speed reducers and the driving motors are respectively controlled by the two frequency converters, and one stop and one start are implemented during overhauling, so that normal work of the other shaft is not affected.

Description

technical field [0001] The invention relates to the field of sludge drying, in particular to a sludge feeder. Background technique [0002] With the development of our country's social economy and cities, the amount of urban sewage production continues to increase. In recent years, the state has actively supported it in terms of policy and financial resources, and built a large number of urban sewage treatment plants to maintain the water environment, prevent and control water pollution, and promote the sustainable development of the national economy and ecological environment. The urban sewage problem has been gradually alleviated. However, the treatment of urban sewage sludge is still a worldwide technical problem. Improper disposal will cause serious secondary pollution, and the problem of harmless treatment of sludge is becoming increasingly serious. [0003] At present, the method usually adopted by sewage treatment plants is to dehydrate the sludge and transport it to...

Problems solved by technology

Due to the high concentration and poor fluidity of this kind of lubricating oil, it is difficult to inject into the general oil injection hole, so it is necessary to refuel when the equipment is stopped.

Affects the daily processing capacity of the equipment, and the more times of starting and stopping due to the maintenance of the bearing housing, the more power is wasted, and it also affects the service life of the whole machine
