Description

Technical Field

[0001] The present application belongs to the technical field of filtering equipment, and in particular, relates to a disc filter. Background Art

[0002] The disc filter is a continuous vacuum filtration device and an indispensable device in the preparation of high-quality iron powder. It is used to eliminate impurities in the medium. When in use, the disc filter will pour the slurry containing minerals into the filter box and achieve continuous filtration through extraction and rotation.

[0003] An existing foreign patent with publication number BR112015026146B1 discloses a disc filter, comprising: a porous ceramic substrate, a porous ceramic membrane layer on the outer surface of the ceramic substrate, and at least one conductive wiring.

[0004] Although the above-mentioned filter is easy to detect, the slow rotation of the filter disc during actual use leads to low fluidity of the slurry. The filter disc cannot quickly adsorb impurities that are far away, and some impurities will sink to the bottom and cannot be filtered, causing the slurry concentration to change continuously, resulting in unstable filtration efficiency. Summary of the invention

[0005] The purpose of this application is to provide a disc filter to address the above-mentioned technical problems, which can improve the stability of slurry filtration efficiency.

[0006] The present application provides a disc filter, comprising:

[0007] Filtration pool;

[0008] A main shaft, wherein the main shaft is movably mounted on the filter tank;

[0009] A plurality of filter discs are provided and mounted on the main shaft;

[0010] A filter tank is placed in the filter tank and corresponds to the filter disc;

[0011] A conveying system connected between the inside and outside of the filter tank;

[0012] Wherein, the conveying system is provided with a pump body.

[0013] The mineral slurry is placed in the filter tank, and the main shaft is driven to rotate by a motor or other driving device to make the filter disc rotate around the main shaft. When the filter disc is immersed in the mineral slurry, filtering is performed through the filter disc, and the filter disc moves in the filter tank. The distance between the filter disc and the inner wall of the filter tank is 3-5cm. The slurry placed outside the filter tank in the filter tank has poor fluidity, and impurities will settle downward. Through the conveying system, this part of the slurry is conveyed to the filter tank through the pump body to keep the slurry concentration in the filter tank relatively stable. The overflowing slurry in the filter tank flows from above to the filter tank with high filtration efficiency.

[0014] Furthermore, the delivery system comprises:

[0015] An extraction pipe is connected to the bottom of the filter tank and is placed outside the filter tank;

[0016] A delivery pipeline connected to the bottom of the filter tank;

[0017] Wherein, the extraction pipeline is connected to the delivery pipeline, and the pump body is installed on the extraction pipeline.

[0018] The bottom of the filter pool is connected by an extraction pipe and is placed in an area outside the filter tank. The filter tank is connected by a delivery pipe to ensure that the slurry outside the filter tank can be continuously transported to the filter tank, keeping the slurry concentration in the filter tank stable and ensuring that the filtering efficiency of the filter disc is relatively stable.

[0019] Furthermore, it also includes:

[0020] Ore transport pipeline, connected to the delivery pipeline;

[0021] The valve body is installed between the ore transport pipeline and the delivery pipeline.

[0022] The ore conveying pipeline is connected to the source of the ore slurry. When the filter pool needs to add ore slurry, the ore conveying pipeline is connected to the delivery pipeline to mix the ore slurry conveyed by the ore conveying pipeline with the ore slurry conveyed by the extraction pipeline and slowly transported to the filter tank at the same time to keep the liquid level in the filter pool and the overall ore slurry concentration stable. When the ore conveying pipeline stops conveying, the valve body is closed to prevent the ore slurry conveyed by the extraction pipeline from flowing back into the ore conveying pipeline. The valve body adopts a solenoid valve, which is easy to control.

[0023] Furthermore, the filtering pool comprises:

[0024] A push plate is placed at the bottom of the filter tank, and a plurality of push plates are provided and correspond to the extraction pipes;

[0025] The push seat is placed on both sides of the push plate and is movably connected to the outer side wall of the filter tank;

[0026] The cavity is mounted on the filter tank;

[0027] The piston is placed in the cavity and connected to the push seat.

[0028] The cavity is connected to the gas source and the control valve. By pumping and transmitting air in the cavity, the movement of the push seat and the push plate is controlled to scrape the precipitated impurities around the connection between the extraction pipeline and the filter tank into the extraction pipeline to prevent a large amount of impurities from accumulating at the bottom of the filter tank. The push plate is installed and connected to the push seat.

[0029] Furthermore, it also includes:

[0030] A scraper, installed on one side of the filter tank and corresponding to the filter disc;

[0031] A guide plate, disposed between adjacent filter discs;

[0032] Wherein, the scraper is installed on the guide plate, and a guide mechanism is arranged between the scraper and the guide plate.

[0033] The filter material on the filter disc is scraped off by the scraper and then collected by the guide plate. The scraper and the guide plate are movably connected by a guide mechanism, so that the scraper can scrape the filter material on the filter disc cleanly and ensure that the scraper will not get stuck with the filter disc.

[0034] Furthermore, the guiding mechanism comprises:

[0035] An articulated shaft, installed between the scraper and the guide plate;

[0036] An elastic member is placed between the scraper and the guide plate;

[0037] Telescopic plate, movably mounted on the scraper;

[0038] The spring is placed between the telescopic plate and the scraper.

[0039] The scraper is hinged to the guide plate through a hinge shaft, and the scraper is deflected in a direction opposite to the rotation direction of the filter disc through an elastic member. The telescopic plate and the spring structure enable the telescopic plate to abut against the filter disc to ensure that the filtered material is scraped cleanly. When the telescopic plate is scraping, the activity between the telescopic plate and the scraper and the rotation of the hinge shaft can prevent the scraper and the filter disc from getting stuck.

[0040] The beneficial effects of this application are:

[0041] 1. Through the conveying system, the slurry at the bottom of the filter pool is transported to the filter tank through the pump body to keep the slurry concentration in the filter tank relatively stable.

[0042] 2. By controlling the movement of the push seat and the push plate, the precipitated impurities around the connection between the extraction pipe and the filter tank are scraped into the extraction pipe to prevent a large amount of impurities from accumulating at the bottom of the filter tank.

[0043] 3. Use the scraper to scrape the filter material off the filter disc, and then collect it through the guide plate. The guide mechanism ensures that the scraper will not get stuck with the filter disc. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The following provides a detailed description of the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0052] Embodiment 1:

[0053] like Figure 1 , Figure 2 As shown, the embodiment of the present application provides a disc filter, comprising:

[0054] Filter tank 100;

[0055] A main shaft 200, wherein the main shaft 200 is movably mounted on the filter tank 100;

[0056] A plurality of filter discs 300 are provided and mounted on the main shaft 200;

[0057] The filter tank 400 is disposed in the filter tank 100 and corresponds to the filter plate 300;

[0058] The conveying system 500 is connected between the inside and the outside of the filter tank 400;

[0059] The conveying system 500 is provided with a pump body 510 .

[0060] The mineral slurry is placed in the filter tank 100, and the main shaft 200 is driven to rotate by a driving device such as a motor, so that the filter disc 300 rotates around the main shaft 200. When the filter disc 300 is immersed in the mineral slurry, filtering is performed through the filter disc 300, and the filter disc 300 moves in the filter tank 400. The distance between the filter disc 300 and the inner wall surface of the filter tank 400 is 3-5 cm. The slurry placed outside the filter tank 400 in the filter tank 100 has poor fluidity, and impurities will settle downward. Through the conveying system 500, this part of the slurry is conveyed to the filter tank 400 through the pump body 510, and the slurry concentration in the filter tank 400 is kept relatively stable. The overflowing slurry in the filter tank 400 flows from the top to the filter tank 100, and has a high filtration efficiency.

[0061] Embodiment 2:

[0062] like Figure 2 As shown, the embodiment of the present application provides a disc filter. In addition to the above technical features, the conveying system 500 further includes:

[0065] The extraction pipeline 520 is connected to the delivery pipeline 530 , and the pump body 510 is installed on the extraction pipeline 520 .

[0066] The bottom of the filter pool 100 is connected through an extraction pipe 520 and is placed in an area outside the filter tank 400, and the filter tank 400 is connected through a delivery pipe 530 to ensure that the slurry outside the filter tank 400 can be continuously delivered to the filter tank 400, keeping the slurry concentration in the filter tank 400 stable, and ensuring that the filtering efficiency of the filter disc 300 is relatively stable.

[0067] Furthermore, it also includes:

[0068] The ore transport pipeline 540 is connected to the delivery pipeline 530;

[0069] The valve body 550 is installed between the ore conveying pipeline 540 and the delivery pipeline 530 .

[0070] The ore conveying pipeline 540 is connected to the source of the ore slurry. When the filter tank 100 needs to add ore slurry, the ore slurry conveyed by the ore conveying pipeline 540 is mixed with the ore slurry conveyed by the extraction pipeline 520 through the connection between the ore conveying pipeline 540 and the delivery pipeline 530, and is slowly transported to the filter tank 400 at the same time to keep the liquid level in the filter tank 100 and the overall ore slurry concentration stable. When the ore conveying pipeline 540 stops conveying, it is closed by the valve body 550 to prevent the ore slurry conveyed by the extraction pipeline 520 from flowing back into the ore conveying pipeline 540. The valve body 550 adopts an electromagnetic valve, which is easy to control.

[0071] Embodiment 3:

[0076] The piston 121 is disposed in the cavity 410 and connected to the push seat 120 .

[0077] The cavity 410 is connected to the air source and the control valve. By pumping and supplying air in the cavity 410, the movement of the push seat 120 and the push plate 110 is controlled to scrape the precipitated impurities around the connection between the extraction pipe 520 and the filter tank 100 into the extraction pipe 520 to prevent a large amount of impurities from accumulating at the bottom of the filter tank 100. The push plate 110 and the push seat 120 are installed and connected.

[0087] The telescopic plate 623 is movably mounted on the scraper 600;

[0088] The spring 624 is placed between the telescopic plate 623 and the scraper 600 .

[0089] The scraper 600 is hinged to the guide plate 610 through the hinge shaft 621, and the scraper 600 is deflected in the direction opposite to the rotation direction of the filter plate 300 through the elastic member 622. The telescopic plate 623 and the spring 624 enable the telescopic plate 623 to abut against the filter plate 300 to ensure that the filtered material is scraped cleanly. When the telescopic plate 623 is scraping, the activity between the telescopic plate 623 and the scraper 600 and the rotation of the hinge shaft 621 can prevent the scraper 600 and the filter plate 300 from getting stuck.
