Problems solved by technology

[0005] 1. The gas-liquid separation of the turntable filter device mainly relies on gravity. Due to the existence of upward vacuum, a high installation height is required to overcome the upward atmospheric pressure and ensure the effect of gas-liquid separation. The required factory building is about 25 meters long, and the required civil construction costs are high.
[0006] 2. The plate height of the traditional turntable filter device is higher than that of the slurry tank, and it is necessary to add a feeding pump to transport the slurry, which increases energy consumption and equipment cost

Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the drawings.

[0030] Such as figure 1 , A rotary disc vacuum filter device, the filter device includes a filter device main body 2 and a built-in gas-liquid separation device 3, the filter device main body 2 includes a washing device and a filter connected to the built-in gas-liquid separation device 3 respectively The disc 7, the feeding device, and the discharging device. The built-in gas-liquid separation device 3 is connected to the vacuum system and the front liquid sealing device 4 through pipelines, and the front liquid sealing device 4 is connected to the drainage pump 6 and the rear liquid sealing device 4 through the pipeline. Liquid sealing device 5. The front liquid sealing device 4 and the rear liquid sealing device 5 are devices that can keep the slight negative pressure generated at the inlet of the drain pump at all times, and are not connected to the outside air.

Abstract

The invention provides a turntable vacuum filter device which comprises a filter device main body and a built-in gas liquid separation device. The turntable vacuum filter device is characterized in that the filter device main body comprises a washing device, a filter disc, a feed device and a discharge device, wherein the filter disc, the feed device and the discharge device are respectively connected with the built-in gas liquid separation device which is connected with a vacuum system and a front liquid seal device by pipelines, and the front liquid seal device is connected with a liquid drainage pump and a rear liquid seal device in sequence by pipelines. According to the turntable vacuum filter device, the mounting height is low, the height of a workshop is only required to be about 10 meters, more than 50% of civil engineering cost is lowered, and as the height of the disc face is lowered, a slurry groove is higher than the disc face, the slurry can flow to the disc face under the action of gravity, no charge pump is needed, the energy consumption is saved, and the equipment cost and the maintenance cost are both reduced.

Description

Technical field [0001] The invention relates to a filter device, in particular to a rotary disc vacuum filter device. Background technique [0002] The filter device is a machine that uses the pressure difference to separate the solid particles and the liquid through the porous medium (filter plate, filter cloth), and the solid forms a filter cake or loose powder. It is mainly used for dewatering non-ferrous metal concentrates, flotation tailings, coal and sludge, and can also be used for solid-liquid separation of suspensions that are not easy to precipitate. It is widely used in mineral processing, food, paper, chemical and sugar, environmental protection, etc. industry. [0003] At present, most of the rotary disc vacuum filter devices used in our country are composed of vacuum system, filter disc, driving device, feeding device, washing device, filter cloth regeneration device, unloading device and electric control box. Due to the vacuum filtration method, the installation he...
