Problems solved by technology

The filter elements used for cross-flow filtration are generally hollow fiber membranes, stainless steel materials, or ceramic materials. According to the specifications of the filtering objects, the filter elements need to be replaced frequently. For the filtration of magnesite, generally larger volume The filter element is made of stainless steel or ceramic material, which is heavy, inconvenient to replace, and requires a lot of labor. Even if the replaced filter element occupies a relatively large area, and the cost is high, the filtration efficiency is reduced.

Embodiment 1

[0038] like figure 1 , 2 , 3, 4, 5, a detachable cross-flow filter for magnesite, including a filter housing 3 with a raw liquid inlet 1 and a filtrate outlet 19, and a filter cavity 4 inside, so The raw liquid inlet is set at one end of the filter shell, and the filtrate outlet is set on the outer surface of the filter shell. And the orifice plate 5 of the filter material storage area 42, the orifice plate 5 and the filter housing 3 are sealed by the orifice plate sealing ring 9, and the two orifice plates are provided with mounting holes 51 for fixing the filter tube system. The system is fixed between the two orifice plates; the filter tube system inlet 61 is connected to the raw liquid inlet, the filter tube system outlet 62 is connected to the filter material storage area, and the filter material storage area is provided with a filter material discharge port 7, and one is connected to the filter processing area. The backwash port 2 also includes a raw liquid inlet contr...

Embodiment 2

[0053] like Image 6 , 7 , 8, 9, in order to facilitate disassembly and cleaning, the filter mesh tube is not directly installed in the installation hole on the orifice plate, but a sub-filter unit composed of a small orifice plate and a filter mesh tube is installed. At this time, the orifice plate 5 set on the filter housing 3 can be called the primary orifice plate, and the small orifice plate set on the primary orifice plate can be called the secondary orifice plate 10 . The diameter should be compatible with the aperture of the primary orifice plate, and the number of the secondary mounting holes 11 on the secondary orifice plate 10 is generally not more than 400. The sealing between the orifice plate 5 and the filter housing 3 and between the orifice plate 5 and the filter mesh tube can be sealed by a filter sealing ring 64 . The sealing between the primary orifice plate and the secondary orifice plate 10 can be sealed by a filter sealing ring 64 . In this embodiment,...

Abstract

The invention relates to the technical field of magnesite filtration, in particular to a detachable cross-flow filter for magnesite and a filtration method thereof, which comprises a filter shell with a raw liquid inlet and a filtrate outlet, and a filter casing is arranged inside. In the filter cavity, there is an orifice plate that divides the filter cavity into a filter treatment area and a filter material storage area. There are installation holes for fixing the filter tube system on the two orifice plates, and the filter tube system is fixed between the two orifice plates. room; the filter material storage area is provided with a filter material discharge port and a backwash port connected with the filter treatment area, and also includes a raw liquid inlet control valve, a filtrate outlet control valve, a filter material discharge port control valve, and a backwash port control valve , feed pump, air compressor, water delivery pump, pressure gauge, and controller, which have a good sealing effect and can meet the requirements of convenient cleaning, disassembly and assembly, and have a large filtering capacity, which reduces labor intensity and is effective The cost is reduced, the degree of automation is high, and the filtration efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of magnesite filtration, in particular to a detachable cross-flow filter for magnesite and a filtration method thereof. Background technique [0002] Magnesite is the main raw material for the extraction of metal magnesium. 2 / 3 of the world's magnesite reserves are concentrated in China, and 1 / 2 of the output is provided by China. In the world magnesite market, China has a pivotal position. As of 1996, a total of 27 magnesite mining areas have been proved nationwide, with 3.001 billion tons of magnesite reserves, distributed in 9 provinces (regions). Liaoning has the most abundant magnesite reserves, accounting for 85.6% of the country's total; Tibet, Xinjiang and Gansu followed. In more than 20 deposits, 10 large mining areas have 94% of the reserves. The world's production capacity of light-burned magnesium is about 2 million tons, and China's output accounts for about 50% of the world's total output. ...
