Description

A Rolling Auxiliary Transmission Mechanism for Filter Press Tracks and Its Application

technical field

The invention relates to the technical field of sludge dewatering, in particular to a rolling auxiliary transmission mechanism for filter press crawlers and an application thereof.

Background technique

In people's daily life and production, a large amount of sludge is produced every year. The recycling method of these sludge can be used as fertilizer for farmland, forest, grassland or desert improvement, etc., as well as for building materials and energy utilization. Since sludge generally contains a large amount of water, the water content is as high as 80%, so in the process of sludge resource treatment, sludge dehydration is a very important link and a common technology.

At present, the commonly used sludge dewatering equipment mainly includes plate and frame sludge dewatering machine, box sludge dewatering machine, belt sludge dewatering machine, centrifugal sludge dewatering machine and so on. Among them, the belt filter press has the advantages of continuous production and low power consumption, and has become relatively more equipment for sludge dewatering. However, in practical applications, the belt filter press still has low pressure and low pressure. The obvious defect of low dryness makes it difficult to meet the current requirements for sludge dewatering. Therefore, a high-pressure flat belt dehydration device is disclosed in the invention patent with application number 201410471557.3. The time is longer than that of the general belt filter press, which can greatly reduce the moisture content of the sludge. However, in the process of use, due to the high pressure, the track used for filter press is under greater pressure, which is prone to generate greater friction, resulting in high energy consumption of the power source, easy to wear, and short service life of the filter press track. Therefore, it is necessary to design a track transmission system that is easy to maintain and reduces friction, so as to increase the service life of the track, reduce maintenance, and reduce energy consumption.
