Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically a high-efficiency and environmentally friendly multi-functional belt filter. Background Technology

[0002] Belt filters, also known as belt press filters, are filtration devices that remove water from slurry by using the squeezing and shearing action between the belts, consisting of two endless filter belts wound around a series of sequentially arranged rollers of varying sizes. Belt filters can be configured into many different models due to different arrangements and combinations of the press rollers. They offer advantages such as simple structure, high dewatering efficiency, large processing capacity, low energy consumption, low noise, high degree of automation, continuous operation, and easy maintenance. Their cost and operating expenses are more than 30% lower than plate and frame filter presses, making them the preferred equipment for urban wastewater treatment. Belt filters are mainly used in industries such as papermaking, printing and dyeing, pharmaceuticals, mining, steel, coal, and leather tanning, and are most commonly used in urban wastewater treatment and industrial sludge dewatering.

[0003] However, currently available continuous belt filters only perform continuous filtration. The liquid is filtered under different vacuum discs in a continuous operation mode, and the filtered liquid is collected in the collection pipe. It cannot distinguish and collect liquids of different concentrations. Furthermore, the filter cake has a relatively high moisture content after filtration, which cannot achieve the purpose of drying and thus reduces the filtration effect. For filter cakes that require lower moisture content, it cannot meet the requirements and must be dried again with other drying equipment. At the same time, most of the belt filters on the market are open-type, which may release harmful media into the air during operation, which is harmful to people and the environment.

[0031] Working principle: In use, firstly, the filter cloth 4 is connected to an external driving power source. The filter cloth 4 can convey solid-liquid separation or solid-liquid medium suspension inside the lower housing 1. The feeding pipe 15 can add the solid-liquid separation or solid-liquid medium suspension into the feed box 5 and then distribute it onto the filter cloth 4. The rotation of the filter cloth 4 conveys the solid-liquid separation or solid-liquid medium suspension. During the conveying process of the solid-liquid separation or solid-liquid medium suspension, under the action of gravity and the filtration of the first vacuum suction cup filter element 901, the second vacuum suction cup filter element 902, and the third vacuum suction cup filter element 903, the filtrate is passed into the interior of the first vacuum suction cup filter element 901, the second vacuum suction cup filter element 902, and the third vacuum suction cup filter element 903 and then discharged from the corresponding collection pipe 904. At this time, the first vacuum suction cup filter element 901, the second vacuum suction cup filter element 902, and the third vacuum suction cup filter element 903 are used. Liquid collection pipes 904 on filter element 902 and third vacuum suction cup filter element 903 discharge liquids of different concentrations respectively. Then, filter cloth 4 transports the filter cake to drying chamber 7 for drying. Then, the power of vertical electric push rod 804 is turned on, driving the first pressure plate 801 and the second pressure plate 802 to move towards filter cloth 4, so that the first pressure plate 801 and the second pressure plate 802 press the filter cake on filter cloth 4 and discharge it from the discharge end 11 under the transmission of filter cloth 4. At this time, the air pressure or hydraulic pressure during the pressing process of filter cake is up to 10 barg. Finally, by setting the air pump 17, the gas in the upper housing 2 is extracted and sent into the interior of the upper housing 2 through the air pump 17, so that the belt filter device is in a closed space in the actual working environment, so that the airtight pressure resistance can reach ±100 mbar.
