Problems solved by technology

Larger consumption, higher cost
During the production process, if the filter cloth of a single filter element and the liquid collection pipe are not tightly sealed, it will also cause the floating substance index of the leaf filter to fail to meet the standard and reduce the production of the equipment.

Embodiment Construction

[0017] Such as figure 1 As shown, a new leaf filter filter device includes a liquid collection pipe 1, a shunt pipe 2, a pipe collar 3, a filler 4, a connecting pipe 5, and a stainless steel mesh 6. There are a plurality of distribution ports under the liquid collection pipe 1, which protrude from the liquid collection pipe 1 to form a distribution pipe 2. The connecting pipe 5 is covered with a stainless steel mesh 6 to form a flow channel. During installation, the head of the shunt pipe 2 and the connecting end of the connecting pipe 5 are respectively wrapped with an alkali-resistant material tape, and the pipe collar 3 is turned with a wrench to lock the shunt pipe 2 and the connecting pipe 5. When the leaf filter is working, the liquid flows from the liquid collection pipe 1 into the distribution pipes 2, and is filtered through the flow channel. Since the connecting pipe 5 is covered with stainless steel mesh 6 to form the flow channel, it replaces the filter sheet and f...

Abstract

The invention discloses a novel leaf filter filtration device, which comprises a liquid collecting pipe, flow division pipes, pipe collars, a filler, connecting pipes and stainless steel meshes. The filtration device is characterized in that the connecting pipes are sheathed with the stainless steel meshes to form flow channels for filtration instead of filter discs and filter cloth, and joints of the flow channels and the flow division pipes are sealed and fixed by the pipe collars and the filler. The filter elements of the filtration device are firm and durable, have good filtering effects, and are not required to be replaced within 2 to 3 years.

Description

technical field [0001] The invention relates to a leaf filter for alumina production equipment, in particular to a novel filter device for the leaf filter. Background technique [0002] Leaf filter is an important equipment in alumina production and is widely used in the filtration equipment of fine filtration operation unit. Among them, in the overflow fine filtration link of sedimentation and separation of red mud, the solid-liquid separation of the leaf filter mainly depends on the internal filter element, and the sealing performance of the filter element determines the level of the float index of the leaf filter. [0003] At present, the filter devices of leaf filter equipment manufacturers at home and abroad are composed of four main components: liquid collection pipe, pressure ring, filter disc, and filter cloth. In general, the service life of filter cloth is about 70-90 days. After the filter cloth completely fails, the equipment needs to be dismantled as a whole, ...
