Description

A rolling auxiliary transmission mechanism for filter press crawlers and its application

Technical field

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

Background technique

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

Currently, the commonly used sludge dehydration equipment mainly includes plate and frame sludge dehydrator, box sludge dehydrator, belt sludge dehydrator, centrifugal sludge dehydrator, etc. Among them, the belt filter press has become a relatively commonly used equipment for sludge dewatering due to its advantages of continuous production and low power consumption. However, in practical applications, the belt filter press also has low filter pressure and low filter pressure. The obvious defect of low dryness makes it difficult to meet the current requirements for sludge dewatering. Therefore, the invention patent with application number 201410471557.3 discloses a high-pressure flat belt dehydration device, which provides a high-pressure belt filtering method. Actual use has proven that its filtering pressure is high and the sludge is pressurized. The time is longer than that of a general-purpose belt filter press, and the moisture content of the sludge can be greatly reduced. However, during use, due to the high pressure, the crawler track used for filter press is under greater pressure and is prone to generate greater friction, resulting in high energy consumption of its power source, easy wear and tear, and short service life of the filter press track. Therefore, it is necessary to design a crawler transmission system that is easy to maintain and reduces friction to increase the service life of the crawler, reduce maintenance, and reduce energy consumption.

Contents of the invention

The purpose of the present invention is to overcome the shortcomings of the prior art and provide a rolling auxiliary transmission mechanism for filter press crawlers, which can better assist the operation of the filter press crawlers and improve the stability and smoothness of the operation of the filter press crawlers. Reduce the energy consumption of its power source.

Another object of the present invention is to provide the application of the rolling auxiliary transmission mechanism for the filter press crawler track, which is flexible and convenient to use.

The technical solution of the present invention is: a rolling auxiliary transmission mechanism for filter press crawlers, including an installation frame, a connecting shaft and rolling parts. A plurality of connecting shafts arranged in parallel are distributed in the installation frame, and each connecting shaft is provided with There are rolling parts, and the surface of the rolling parts is connected with the filter press track and produces relative motion. Among them, on the one hand, the installation frame serves as a support component for connecting shafts and rolling elements, fixing each connecting shaft and rolling elements to form an independent rolling unit; on the other hand, each rolling auxiliary transmission mechanism acts as an independent rolling unit, each The rolling units are spliced together based on the installation frame to form an auxiliary transmission mechanism that is suitable for the filter press crawler track.

The installation frame includes a plurality of partitions and side fixing assemblies. The plurality of partitions are arranged in parallel along the axial direction of the connecting shaft. Both sides of each partition are fixedly connected by side fixing assemblies. The setting of the partition is mainly used to cooperate with the following rolling elements to separate each rolling element for easy installation. At the same time, it also avoids mutual interference when the rolling elements on the same connecting shaft are used.

The partition is an integrated structure, with connecting holes distributed on the partition, and each connection hole is connected to a connecting shaft; the same connecting shaft passes through the connecting holes at corresponding positions on each partition. When installing the partitions of this structure, first connect the connecting holes and rolling elements on each partition to the corresponding connecting shaft alternately in series. The two ends of each connecting shaft are locked or welded with fixed elements, and then the connecting holes and rolling elements on each partition are installed. Just weld the side fixing components on both sides of the board. The partition of this structure is easy to make and can be formed at one time.

The partition is a combined structure, including a partition body and an upper fixed strip. There are through slots with upper openings distributed on the partition body. Each through slot is connected to a connecting shaft, and the same connecting shaft passes through each partition.

When there is local damage, the corresponding rolling parts can be replaced as needed. The use is very flexible and can effectively reduce the maintenance cost of the equipment. On the other hand, due to the large surface area of the filter press track, the pressure The weight of the filter track is also very large. Therefore, if multiple rolling parts are used in combination, the auxiliary power will be greater than that of one roller, and the auxiliary transmission effect will be significantly improved. At the same time, it can also reduce the overall weight of the rolling auxiliary transmission mechanism. , to achieve the purpose of simplifying the equipment.
