Problems solved by technology

[0003] When existing cryolite manufacturers filter and recycle aluminum fluoride solution, workers generally need workers to manually discharge the filtered silica particles from the filter plate. Not only the filter equipment is easily damaged, but also the production efficiency is low.
Some manufacturers have purchased a rotary filter for filtration, but the structure of the scraping device of the filter is fixed, and it cannot be adjusted according to the feeding speed of the solution to be filtered and the content of particles in the solution, and the filtration efficiency is low.

Embodiment 1

[0023] Embodiment 1: as Figure 1~4 Shown: a scraping device for a filter and a matching filter plate, including a scraper 5 and a mounting bracket 1, the scraper 5 is an arc-shaped structure with the scraper surface protruding outward; the scraper 5 is installed through an arc adjustment device and an angle adjustment device On the mounting frame, it is arranged above the filter plate 11 in an inclined manner.

[0024] The angle adjustment device includes three angle adjustment rods 4 arranged horizontally and corresponding sliders 3. The slider 3 is installed on the slide rail 2 of the mounting bracket 1 in a manner that can move up and down. It is hinged with the upper part of the scraper 5 , and the slider 3 is provided with a locking screw 14 for fixing with the mounting bracket 1 . By adjusting the slider 3 up and down, the angle adjusting rod 4 can be driven to move up and down, thereby adjusting the inclination angle of the scraper 5 .

[0025] The arc adjustment dev...

Embodiment 2

[0029] Embodiment 2: as Figure 5 Shown: compared with embodiment 1, the difference between a kind of filter scraping device and the matching filter plate of this embodiment is that the filter plate 11 is a conical structure that protrudes upwards in the middle, and the filter plate 11 is set as The conical structure can speed up the discharge speed of silica particles and improve the efficiency of filtration and recovery.

[0030] Working principle and using method of the present invention:

[0031] When performing filtration and recovery, the scraping device and its supporting filter plate 11 are installed on the rotary filter, and the driving device 13 of the rotary filter drives the casing 12 and the filter plate 11 to rotate, and the aluminum fluoride solution containing silicon dioxide particles After falling into the filter plate 11, the aluminum fluoride solution is filtered through the filter plate 11, and the silica is left on the filter plate 11. As the filter plat...

Abstract

The invention discloses a scraping device for a filter and a matched filter plate. The scraping device comprises a scraping plate and a mounting bracket, wherein the scraping plate is an arc-shaped structure of which a scraping surface is protruded outwards; the scraping plate is installed on the mounting bracket through a radian adjusting device and an angle adjusting device, and is arranged above the filter plate in an inclined manner. The scraping device is simple in structure and high in filter efficiency, and the arc and mounting angle of the scraping device can be adjusted according to the blanking speed of a solution needing to be filtered and the content of particles in the solution.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a scraping device for a filter and a matching filter plate. Background technique [0002] Cryolite is an indispensable flux in aluminum smelting, and it is also widely used in other industries. In the production process of cryolite, in order to improve the utilization efficiency of raw materials, it is necessary to filter out the mixed silicon dioxide particles in the aluminum fluoride solution, so as to recycle the aluminum fluoride solution. [0003] When existing cryolite manufacturers filter and recycle aluminum fluoride solution, workers generally need workers to manually discharge the filtered silicon dioxide particles from the filter plate. Not only the filter equipment is easily damaged, but also the production efficiency is low. Some manufacturers have purchased a rotary filter for filtration, but the structure of the scraping device of the filter is fi...
