Description

Technical Field

[0001] This utility model belongs to the technical field of filter press equipment, specifically relating to a high-efficiency filter press for iron ore concentration and dewatering. Background Technology

[0002] A filter press is a special filtration machine that applies pressure to a material to cause liquid to seep out. It was first used in chemical production in the early 18th century and is still widely used in industries such as chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramics, and environmental protection.

[0003] Existing high-efficiency filter presses used for iron ore concentration and dewatering mostly adopt a single filter belt form, which means that the filter plates need to be separated one by one for unloading. This results in low unloading efficiency, wastes a lot of time, and has certain limitations. Summary of the Invention

[0004] The purpose of this invention is to address the problem of existing high-efficiency filter presses for iron ore concentration and dewatering that use a single filter belt, and to provide a filter press for iron ore concentration and dewatering. This device can quickly unload the filter plates after the material has been concentrated by pressure filtration, and can prevent the material from sticking to the surface of the filter plates and being unable to flow, thereby improving the processing efficiency of slurry concentration and dewatering.

[0005] A filter press for iron ore concentration and dewatering includes a processing table, a fixed plate, a connecting block, a connecting plate, a slide bar, a threaded rod, a drive device, a filter plate, a sliding plate, a connecting chain, and a vibration device.

[0006] A discharge port is located at the center of the processing table surface. Fixed plates are fixedly connected to both sides of the processing table. A vibration device is located at the top of the fixed plates, and a connecting block is located at the top of the vibration device. The connecting block is fixedly connected to the top connecting plate. Two sliding rods are fixedly connected between the two connecting plates. A threaded rod is also located between the two sliding rods, with one end of the threaded rod inserted into one side of the connecting plate and the other end passing through the other side of the connecting plate and connecting to the drive device. Several filter plates are included, each comprising a frame and filter plates disposed within the frame. A suspension device is located at the top of the filter plate frame. The filter plate has a hanging hole for mounting the filter plate onto the slide rod, and each of the two sides of the filter plate has a fixed lug with a hole. The sliding plate is located outside the filter plates. The top of the sliding plate has a through hole for mounting on the slide rod and an internal thread hole for threaded connection with the threaded rod. Each side of the sliding plate has a connecting chain fixing protrusion with a through hole. The fixed lug on one side of the filter plate and the connecting chain fixing protrusion on one side of the sliding plate are fixedly connected to one connecting chain, and the fixed lug on the other side of the filter plate and the connecting chain fixing protrusion on the other side of the sliding plate are fixedly connected to another connecting chain.

[0007] The vibration device includes a connecting column, a spring body, a reinforcing column, and a vibrator. The connecting column is located at the top of the fixed plate, the bottom end of the spring body is fixedly connected to the top end of the connecting column, the top end of the spring body is fixedly connected to the connecting block, the bottom surface of the connecting block has a groove, the spring body has a reinforcing column inside, the bottom end of the reinforcing column is fixedly connected to the top end of the connecting column, the top end of the reinforcing column is inserted into the groove on the bottom surface of the connecting plate, and the vibrator is fixedly connected to the bottom end of the connecting plate.

[0008] Furthermore, the aforementioned filter press for iron ore concentration and dewatering includes a drive unit comprising a motor housing, a drive motor housed within the motor housing, and a battery connected to the drive motor. The motor housing is mounted on a connecting plate, and the drive motor is connected to a threaded rod.

[0009] Furthermore, in the aforementioned filter press used for iron ore concentration and dewatering, the inner diameter of the groove at the bottom of the connecting plate is the same as the inner diameter of the spring body.

[0010] Furthermore, in the aforementioned filter press for iron ore concentration and dewatering, the connecting chain is formed by several connecting rings interlocking with each other. The connecting rings at both ends of the connecting chain are respectively fitted into the through holes of the connecting chain fixing protrusion on one side of the sliding plate, and the remaining connecting rings are respectively fitted into the through holes of the fixing ears on one side of the filter plate.

[0011] Furthermore, in the aforementioned filter press for iron ore concentration and dewatering, the power source for the vibrator is either a battery of the drive unit or an external power source.

[0012] The beneficial effects of this utility model are:

[0013] 1. The filter press of this utility model uses the fixing lugs of the filter plates and the connecting chain fixing protrusion of the sliding plate to pull the chain, which can quickly disperse multiple filter plates, thereby quickly unloading the filter plates after the material is pressed and concentrated. This effectively avoids the disadvantage of slow unloading speed of a single plate, improves the unloading speed, and speeds up the processing efficiency.

[0014] 2. The filter press of this utility model can generate vibration by connecting an external power source through a vibrator during unloading, thereby shaking off the concentrated minerals and preventing them from sticking to the surface of the filter plate and making it easier to discharge during the production process.

[0018] Example 1

[0019] A filter press for iron ore concentration and dewatering, see Figures 1-2 It includes a processing table 1, a fixed plate 2, a connecting block 16, a connecting plate 15, a slide bar 3, a threaded rod 5, a drive device 6, a filter pressure plate 4, a sliding plate 12, a connecting chain 8, and a vibration device.

[0020] A discharge port 9 is located at the center of the processing table surface. This discharge port facilitates the discharge of concentrated iron ore from the filter press into the next process. Fixed plates are fixedly connected to both sides of the processing table. A vibration device is located at the top of each fixed plate, and a connecting block is located at the top of the vibration device. The connecting block is fixedly connected to the top connecting plate. Two sliding rods are fixedly connected between the two connecting plates. A threaded rod 5 is located between the two sliding rods and between the two connecting plates. One end of the threaded rod is inserted into one side of the connecting plate, and the other end passes through the other side of the connecting plate and connects to the drive device. Several filter plates are included, each comprising a frame and filter plates housed within the frame. The top of the filter plate frame has a hanging hole for mounting the filter plate onto the sliding rods. Each of the two sides is provided with a fixed lug 7 with a hole; there are two sliding plates, located on both sides of several filter plates respectively. The top of the sliding plate is provided with a through hole for fitting on the sliding rod and an internal threaded hole for threaded connection with the threaded rod. Each side of the sliding plate is provided with a connecting chain fixing protrusion 17 with a through hole. The fixed lug on one side of the filter plate and the connecting chain fixing protrusion on one side of the sliding plate are fixedly connected to one connecting chain. The fixed lug on the other side of the filter plate and the connecting chain fixing protrusion on the other side of the sliding plate are fixedly connected to another connecting chain. The connecting chain is formed by several connecting rings interlocking with each other. The connecting rings at both ends of the connecting chain are respectively fitted into the through holes of the connecting chain fixing protrusion on one side of the sliding plate, and the remaining connecting rings are respectively fitted into the through holes of the fixed lug on one side of the filter plate.

[0021] The vibration device includes a connecting column, a spring body, a reinforcing column, and a vibrator. The connecting column is located at the top of a fixed plate, and the bottom end of the spring body is fixedly connected to the top end of the connecting column. The top end of the spring body is also fixedly connected to the connecting plate. The connecting plate is elastically connected, allowing it to move. The spring body contains a reinforcing column, the bottom end of which is fixedly connected to the top end of the connecting column. The top end of the reinforcing column is inserted into a groove at the bottom end of the connecting plate. The inner diameter of the groove at the bottom end of the connecting plate is the same as the inner diameter of the spring body. The vibrator is fixedly connected to the bottom end of the connecting plate. The power source for the vibrator is a battery from a drive device or an external power source. The reinforcing column ensures the stability of the connecting plate during its movable connection, preventing the connecting plate from shifting due to the spring's inability to guarantee stability.

[0022] The drive device includes a motor housing, a drive motor housed inside the motor housing, and a battery connected to the drive motor. The motor housing is mounted on a connecting plate. The drive motor is connected to a threaded rod. The battery provides power to the drive motor, enabling the drive motor to drive the threaded rod to rotate.

[0023] In conventional filter presses, after the filtration and concentration process, the pressed filter plates need to be manually separated one by one, and the iron ore filter cake adhering to the plates needs to be knocked off before being collected and transported to the next process. In the technical solution of this invention, after the filtration and concentration process is completed, the drive motor of the drive unit is started. The drive motor drives the threaded rod to rotate, and the rotation of the threaded rod drives the sliding plate to slide horizontally via the thread. During the horizontal movement, the sliding plate, through the connected chain, pulls the remaining filter plates to quickly disperse, thereby completing the joint unloading. This design allows multiple filter plates to quickly disperse, enabling rapid unloading of the concentrated ore plates, effectively avoiding the slow unloading speed of individual plates, improving unloading speed, and accelerating processing efficiency.

[0024] In addition, this technical solution also incorporates springs and vibrators. Due to the elastic connection of the springs, when the power is turned on by the vibrator, the connecting plate can drive the slide rod and the filter plate to vibrate together, thereby shaking off the concentrated minerals and preventing them from sticking to the surface of the filter plate and being unable to be discharged. Moreover, the stability of the connecting plate can be maintained by the reinforcing column.

[0025] After unloading, the filter press can be used again for iron ore slurry filtration and concentration.
