Problems solved by technology

All three types of dehydration equipment have their own disadvantages
[0004] At present, the existing sludge dehydration methods include thermal drying, chemical methods, etc., but they have the following problems: thermal drying of sludge has a large one-time investment, high energy consumption and operating costs, and is likely to cause secondary dehydration. Pollution and high requirements for management and operation technology, etc., chemical methods have problems such as large amount of chemicals used and high costs of chemicals

Abstract

The invention relates to a multi-layer roll press filter belt type sludge deep dewatering machine, which belongs to the technical field of environmental geotechnical engineering. The multi-layer roll press belt type sludge deep dewatering machine consists of a pressure-bearing drying drum, a cleaning drum, a gear motor, a drive chain, a transmission chain, a hydraulic cylinder, a lower pressure tile, a lower pressure tile sealing strip, a mud cake collection tank, Discharge hopper, mud cake scraper, filter belt, discharge control valve, feed hopper, reversing roller, upper pressure tile, upper pressure tile sealing strip, limit contact, angle limiter, upper pressure tile rocker It is composed of a frame. After the sludge is fed, the deceleration motor is reversed to make the mud sample roll up on the pressure-bearing drying drum in multiple layers. The upper and lower pressure tiles of the two-stage four-bar mechanism are powered by hydraulic cylinders. The rolled up sludge is hugged tightly and pressurized to achieve deep dehydration of the sludge. The invention has reasonable design, simple structure and convenient operation, can further deep dehydrate and dry the sludge after mechanical dehydration treatment in sewage treatment plants, and has low treatment cost and low energy consumption.

Description

technical field [0001] The invention relates to a multi-layer roll press filter belt type sludge deep dewatering machine, which belongs to the technical field of environmental geotechnical engineering. Background technique [0002] Sludge is the product of sewage treatment. Most of the pollutants in sewage are transferred to sludge. Sludge that has not been properly treated and disposed of enters the environment and brings secondary pollution to water, soil and the atmosphere. pose a serious threat to human health. With the rapid improvement of my country's sewage treatment capacity, sludge production has increased sharply. According to the data of "Public Utilities Industry: Sludge Treatment Market Is Imminent" by China Solid Waste Network, the national wet sludge production in 2015 was nearly 40 million tons, with an annual average of 40 million tons. The growth rate is greater than 20%, and the sludge treatment situation in my country is severe. [0003] The high water c...
