Description

Technical Field

[0001] This utility model relates to the field of ceramic filter technology, specifically an improved iron concentrate ceramic filter. Background Technology

[0002] Iron concentrate is the refined product of iron ore after beneficiation and is one of the main raw materials for the steel industry. In the production process of iron concentrate, in order to improve metal recovery rate and reduce production costs, it is usually necessary to filter the iron concentrate to remove moisture and obtain dry concentrate powder.

[0003] Ceramic filters, as a highly efficient solid-liquid separation device, are widely used in the filtration process of iron concentrate. Traditional ceramic filters typically consist of a circular or rectangular filter chamber containing ceramic filter plates. A vacuum pump generates negative pressure, forcing the filtrate through the micropores on the ceramic filter plates to be discharged, thereby achieving solid-liquid separation.

[0004] In the filter box, solid particles in the iron concentrate slurry will settle at the bottom, causing the water content to surge during the formation of the filter cake, resulting in poor filtration effect. The filtered iron concentrate cannot meet the requirements for subsequent use. Therefore, we propose an improved iron concentrate ceramic filter to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an improved ceramic filter for iron concentrate, which solves the problem that solid particles in the iron concentrate slurry will settle at the bottom, causing a surge in water content during the formation of the filter cake, resulting in poor filtration effect and the filtered iron concentrate not meeting the requirements for subsequent use.

A first gear is fixedly mounted on the surface of the rotating shaft near the motor end. A second gear, meshing with the first gear, is rotatably mounted on the surface of the support plate near the motor position via a first rotating shaft. A rotating disk is also fixedly mounted on the first rotating shaft. A movable pin is fixedly mounted on the surface of the rotating disk at a non-center position. A movable plate is provided on one side of the rotating disk. The movable plate has a strip-shaped sliding opening adapted to the sliding of the movable pin. A sector gear is fixed to one end of the movable plate. The device is rotatably mounted on the support plate via a second rotating shaft.

[0022] like Figure 1-3 As shown:

[0023] An improved iron concentrate ceramic filter includes a support 101, a filter housing 102 fixedly mounted on the support 101, a ceramic filter plate 103 disposed inside the filter housing 102, and a motor 105 fixedly mounted on the support 101 to drive the ceramic filter plate 103 to rotate.

[0024] A baffle plate 106 is disposed inside the filter housing 102;

[0025] The reciprocating linkage mechanism 2 is mounted on the bracket 101. The motor 105 drives the reciprocating linkage mechanism 2 to move the baffle 106 back and forth, which is used to agitate the liquid at the bottom of the filter housing 102.

[0026] The bracket 101 is fixed with symmetrically arranged support plates. The two sets of support plates are rotatably mounted with a rotating shaft through bearings. The ceramic filter plate 103 is fixed on the surface of the rotating shaft. The output end of the motor 105 is fixedly connected to one end of the rotating shaft through a coupling.

[0027] The reciprocating linkage mechanism 2 includes L-shaped frames 208 symmetrically arranged on the upper surface of the bracket 101 near the motor 105. A first gear 201 is fixedly mounted on the surface of the rotating shaft near the motor 105. A second gear 202, meshing with the first gear 201, is rotatably mounted on the surface of the support plate near the motor 105 via a first rotating shaft. A rotating disk 203 is also fixedly mounted on the first rotating shaft. A movable pin 204 is fixedly mounted on the surface of the rotating disk 203 at a non-center position. A movable plate 205 is provided on one side of the rotating disk 203. The movable plate 205 has a strip-shaped sliding opening adapted to the sliding of the movable pin 204. A sector gear 206 is fixed to one end of the movable plate 205. A section of the surface of the movable plate 205 near the sector gear 206 is provided. The device is rotatably mounted on the support plate via the second rotating shaft. Two sets of L-shaped frames 208 are slidably mounted with gear rods 207 through the opened sliding holes. The tooth surfaces of the gear rods 207 mesh with the tooth surfaces of the sector gears 206. A rack 209 is fixedly mounted on the surface of the gear rods 207 via the support rod. A third gear 211 that meshes with the rack 209 is rotatably mounted on the side of the support plate away from the second gear 202 via the connecting shaft. A rotating sleeve 213 is rotatably mounted on the side of the two sets of support plates that are close to each other via the bearing. A fourth gear 212 that meshes with the third gear 211 is fixedly mounted on the surface of the rotating sleeve 213. A connecting rod 214 is fixedly mounted on the surface of the rotating sleeve 213. The other end of the connecting rod 214 is fixedly connected to the spoiler 106.

[0028] The rotating sleeve 213 and the rotating shaft are designed concentrically. A limiting plate 210 is fixedly installed on one side of the rack 209 near the L-shaped frame 208. A limiting groove adapted to the limiting plate 210 is opened on one side of the L-shaped frame 208. The limiting plate 210 can slide in the limiting groove opened in the L-shaped frame 208.

[0029] A protective cover 104 is fixedly installed on the upper surface of the bracket 101 to shield and protect the reciprocating linkage mechanism 2.

[0030] In this embodiment: When the improved iron concentrate ceramic filter is working, the iron concentrate slurry to be processed is fed into the feed inlet of the ceramic filter and discharged into the filter housing 102. In the iron concentrate slurry, solid particles and liquid are mixed together. The rotating shaft (not shown in the figure) is driven to rotate by the motor 105, which in turn drives the ceramic filter plate 103 to rotate. Under negative pressure, the iron concentrate slurry passes through the ceramic filter plate 103. Due to the characteristics of the microporous ceramic filter plate 103, solid particles cannot pass through and are therefore trapped on the surface of the ceramic filter plate 103, forming a filter cake layer. The liquid, however, passes smoothly through the microporous structure and enters the gas-liquid distribution device.

[0031] As the liquid passes through the ceramic filter plate 103, solid particles gradually accumulate on the ceramic filter plate 103 to form a filter cake layer, thereby achieving solid-liquid separation. After the filtration and dehydration process is completed, the filter cake layer is scraped off the ceramic filter plate 103 by a scraper (not shown in the figure) on the filter housing 102 for subsequent processing or transportation.

[0032] While the motor 105 drives the rotating shaft to rotate, it also drives the first gear 201 to rotate synchronously. The first gear 201 meshes with the second gear 202, thereby driving the second gear 202 to rotate. The second gear 202 can drive the rotating disk 203 to rotate, and the rotating disk 203 drives the movable pin 204 to rotate synchronously. At this time, the movable pin 204 slides in the strip-shaped sliding mouth opened in the movable plate 205. The rotating disk 203 drives the movable pin 204 to rotate continuously, thereby driving the movable plate 205 to swing back and forth on the support plate through the second rotating shaft, and at the same time driving the sector gear 206 to swing back and forth synchronously.

[0033] Since the tooth surface of the sector gear 206 meshes with the tooth surface of the gear rod 207, the sector gear 206 can drive the gear rod 207 to slide back and forth in the sliding holes on the two sets of L-shaped frames 208.

[0034] Meanwhile, the gear rod 207 drives the rack 209 to reciprocate through the support rod. Since the rack 209 is meshed with the third gear 211, the reciprocating movement of the rack 209 drives the third gear 211 to reciprocate. Since the third gear 211 is meshed with the fourth gear 212, the fourth gear 212 rotates accordingly, thereby driving the rotating sleeve 213 and the connecting rod 214 to swing back and forth synchronously. With the movement of the connecting rod 214, the baffle 106 swings back and forth synchronously at the bottom of the filter housing 102, which helps to reduce the sedimentation of solid particles in the filter housing 102.

[0035] This solution reduces the sedimentation of solid particles during the filtration process, allowing them to be more evenly distributed on the ceramic filter plate 103, thus improving filtration efficiency and ensuring filtration effect. Because the moisture content of the filter cake is reduced, the quality of the filtered iron concentrate powder is improved, which helps meet the high standards of industrial production and enhances the product's market competitiveness.

[0036] The rack 209 slides in the limiting groove opened in the L-shaped frame 208 through the limiting plate 210. On the one hand, it can limit the rotation of the gear rod 207, and on the other hand, it can ensure the stable meshing of the rack 209 during the movement.

[0037] It should be noted that all electrical equipment involved in this product is powered by an external power source. The solution also includes an electrical control cabinet, which is mounted on bracket 101. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is a mature existing technology and is well known to those skilled in the art, so it will not be described in detail here.

[0038] Meanwhile, the contents of the ceramic filter plate 103 not described in detail in this specification are all prior art known to those skilled in the art, and can be referred to in patent document CN215586781U for details.

[0039] Furthermore;

[0040] In an optional embodiment, the surface of the spoiler 106 has multiple sets of through holes.

[0041] In this embodiment, the surface of the baffle 106 is provided with multiple sets of through holes. Liquid flows through the through holes of the baffle 106, thereby reducing resistance and improving the stability of the connection between the baffle 106 and the connecting rod 214.

[0042] The working principle and usage process of this utility model are as follows: When the improved iron concentrate ceramic filter is working, the rotating shaft (not shown in the figure) is driven to rotate by the motor 105, which in turn drives the ceramic filter plate 103 to rotate. Under negative pressure, the iron concentrate slurry passes through the ceramic filter plate 103. Due to the characteristics of the microporous ceramic filter plate 103, solid particles cannot pass through and are therefore trapped on the surface of the ceramic filter plate 103, forming a filter cake layer, thereby achieving solid-liquid separation. After completing the filtration and dewatering process, the filter cake layer is scraped off the ceramic filter plate 103 by the scraper (not shown in the figure) on the filter housing 102 for subsequent processing or transportation. At the same time as the motor 105 drives the rotating shaft to rotate, it also drives the first gear 201 to rotate synchronously. The first gear 201 meshes with the second gear 202, which in turn drives the second gear 202 to rotate. The second gear 202 can drive the rotating disk 203 to rotate, and the rotating disk 203 drives the movable pin 204 to rotate synchronously. At this time, the movable pin 204 is in the movable plate 205. The slide is designed to slide within the strip-shaped sliding opening. The rotating disk 203 drives the movable pin 204 to rotate continuously, which in turn drives the movable plate 205 to reciprocate on the support plate via the second rotating shaft. Simultaneously, this drives the sector gear 206 to reciprocate synchronously. Since the tooth surfaces of the sector gear 206 mesh with the tooth surfaces of the gear rod 207, the sector gear 206 can drive the gear rod 207 to reciprocate within the sliding holes on the two sets of L-shaped frames 208. At the same time, the gear rod 207 drives the rack 209 to reciprocate via the support rod. As the rack 209 meshes with the third gear 211, the reciprocating movement of the rack 209 drives the third gear 211 to reciprocate. As the third gear 211 meshes with the fourth gear 212, the fourth gear 212 rotates accordingly, thereby driving the rotating sleeve 213 and the connecting rod 214 to reciprocate synchronously. With the movement of the connecting rod 214, the baffle 106 reciprocates synchronously at the bottom of the filter housing 102, which helps to reduce the sedimentation of solid particles inside the filter housing 102.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
