Description

A pressurized iron concentrate dewatering device Technical Field

[0001] This utility model relates to the field of iron concentrate dehydration, and in particular to a pressurized iron concentrate dehydration device. Background Technology

[0002] In the production and processing of iron concentrate, dehydration is a crucial step. Excessive moisture content in iron concentrate increases transportation costs, makes it prone to clumping during storage, affects product quality, and also has an adverse impact on subsequent smelting and other processing steps, reducing production efficiency and increasing energy consumption.

[0003] Currently, traditional iron concentrate dewatering equipment uses a simple pressurization method combined with filtration for dewatering. However, even when using filter cloth, the filter screen may still need to be cleaned during the processing. Although the filter cloth can block most of the iron concentrate, some fine particles or impurities may pass through the filter cloth and adhere to the surface of the filter screen. Over time, these deposits will affect the water passage capacity of the filter screen and reduce the dewatering efficiency. Moreover, manual cleaning requires stopping the machine and incurs labor and time costs, resulting in low maintenance efficiency and reduced processing efficiency. Therefore, a pressurized iron concentrate dewatering device is proposed to solve the above problems. Summary of the Invention

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Referring to Figures 1, 3, and 4, one embodiment of this utility model provides a pressure-type iron concentrate dewatering device, comprising a pressure frame 1, a pressure rod 2, and a pressure plate 3. The pressure rod 2 is fixedly installed at the top of the pressure frame 1, and its bottom output end passes through the pressure frame 1 and is fixedly connected to the pressure plate 3. A cylinder 4 is provided inside the pressure frame 1, and a water outlet is provided on the outer wall of the cylinder 4. A filter cylinder 5 is provided inside the cylinder 4, and the pressure plate 3 is inserted into the inner wall of the filter cylinder 5. The pressure frame 1, pressure rod 2, pressure plate 3, filter cylinder 5, and cylinder 4 are all structural components of a hydraulic dewatering machine. A cleaning mechanism is provided between the filter cylinder 5 and the cylinder 4. The cleaning mechanism includes a cleaning component 7, which includes a support for two sets of cleaning frames 71. Two sets of fixing rings 74 are slidably connected to the inner wall of the cylinder 4. Cleaning frames 71 supporting fixing plates 73 are fixedly connected to the front and rear inner walls of the two sets of fixing rings 74. Fixing plates 73 supporting cleaning brushes 72 are provided on the inner side of the two sets of cleaning frames 71. Multiple sets of cleaning brushes 72 that can clean the outer wall and holes of the filter cylinder 5 are fixedly connected to the inner side of the two sets of fixing plates 73. The multiple sets of cleaning brushes 72 are correspondingly arranged with respect to the holes of the filter cylinder 5, and the diameter of the cleaning brushes 72 is smaller than the diameter of the holes of the filter cylinder 5, so that the cleaning brushes 72 can be inserted into the holes of the filter cylinder 5. Thus, the holes of the filter cylinder 5 can be cleaned by inserting the cleaning brushes 72 into the holes of the filter cylinder 5, thereby improving the filtration efficiency.

[0029] Referring to Figures 1, 2, and 3, the cleaning mechanism also includes a transmission assembly 6. The transmission assembly 6 includes a gear ring 61 that drives the fixed ring 74, the cleaning frame 71, and the cleaning brush 72 to rotate. The gear ring 61 is fixedly connected to the outer wall of the fixed ring 74. Two sets of fixed brackets 64 supporting the servo motor 63 are fixedly connected to the upper part of the rear surface of the cylinder 4. The servo motor 63 that drives the drive gear 62 to rotate is fixedly installed between the two sets of fixed brackets 64. The top end of the output shaft of the servo motor 63 passes through the fixed bracket 64 and is fixedly connected to the drive gear 62 that drives the gear ring 61 to rotate. The drive gear 62 meshes with the outer wall of the gear ring 61.

[0030] Referring to Figures 2, 3, and 4, an installation component 8 is provided on the inner side of the cleaning frame 71. The installation component 8 includes a mounting groove 82 for inserting mounting block two 83 and mounting block one 81. Mounting block two 83, which supports and fixes long plate 73, is inserted into the inner wall of the mounting groove 82. The long plate 73 is fixedly connected to the inner side of mounting block two 83. Both the mounting groove 82 and mounting block two 83 are rectangular with dovetail grooves. Mounting block one 81, which limits the position of mounting block two 83, is inserted into the inner wall of the mounting groove 82 at the top of mounting block two 83. Mounting block one 81 is T-shaped, and the bottom of the downward extension of the T-shape of mounting block one 81 is also dovetail-shaped. Mounting block one 81 is T-shaped and has the same length and width as the cleaning frame 71, so it can be installed at the top of the cleaning frame 71 to limit mounting block two 83. At the same time, mounting block two 83... Both mounting block 81 and mounting slot 82 are designed in a dovetail shape to improve installation stability. After mounting block 83 and mounting block 81 are inserted into mounting slot 82, they can only be moved out from the top. With the help of threaded rod 84, mounting block 81 is limited to a stable position, which also facilitates subsequent replacement and maintenance. Threaded rods 84 are inserted into the top left and right sides of mounting block 81. Threaded slots 85 are opened on the top left and right sides of cleaning frame 71. Both sets of threaded rods 84 pass through the top left and right horizontal ends of mounting block 81 and are threaded into the inner wall of the threaded slots 85. After passing through mounting block 81, the threaded rods 84 are threaded into the threaded slots 85 to stably limit the mounting blocks 81 and 83 and the cleaning brush 72.

[0031] Working principle: When in use, place the iron concentrate to be dehydrated inside the filter cylinder 5 using a filter cloth, start the pressure rod 2, and under the support of the pressure frame 1, the output end of the pressure rod 2 pushes the pressure plate 3 downward. Since the pressure plate 3 is inserted into the inner wall of the filter cylinder 5, as the pressure plate 3 presses down, pressure is applied to the iron concentrate. Under the action of pressure, the water in the iron concentrate is squeezed out and discharged through the holes of the filter cylinder 5 into the space between the filter cylinder 5 and the cylinder body 4, thus completing the initial dehydration.

[0032] During the dehydration process, to prevent the holes of the filter cylinder 5 from being clogged by iron concentrate and affecting the dehydration efficiency, the cleaning mechanism is activated, and the servo motor 63 is turned on. The output shaft of the servo motor 63 drives the drive gear 62 to rotate. Because the drive gear 62 meshes with the gear ring 61, and the gear ring 61 is fixed to the outer wall of the fixed ring 74, the rotation of the drive gear 62 will drive the gear ring 61, the fixed ring 74, and the connected cleaning frame 71, fixed long plate 73, and cleaning brush 72 to rotate together. During the rotation, when the cleaning brush 72 is aligned with the holes of the filter cylinder 5, its flexibility allows it to be inserted into the holes of the filter cylinder 5 to clean them, so that water can pass through the filter cylinder 5 smoothly, continuously maintaining the filtration performance of the filter cylinder 5, thereby improving the dehydration efficiency.

[0033] When the cleaning brush 72 wears out after a period of use and needs to be replaced, first unscrew the threaded rod 84 to disengage it from the threaded groove 85 at the top of the cleaning frame 71. After removing the threaded rod 84, the mounting block 1 81 can be lifted upwards. Since mounting block 1 81, mounting block 2 83, and mounting groove 82 are all dovetail-shaped, mounting block 1 81 and mounting block 2 83 are tightly connected and can only be moved from above. Therefore, after lifting mounting block 1 81, mounting block 2 83 can also be removed from the mounting groove 82, allowing the cleaning brush 72 fixed inside mounting block 2 83 to be removed and replaced. After replacement, insert the mounting block 2 83 corresponding to the new cleaning brush 72 into the mounting groove 82, then place mounting block 1 81 on top, ensuring that the T-shaped bottom of mounting block 1 81 mates with mounting block 2 83. Finally, screw on the threaded rod 84 to fix mounting block 1 81 and mounting block 2 83 onto the cleaning frame 71, completing the replacement and maintenance of the cleaning brush 72. This operation is convenient and ensures the normal operation of the device in the future. Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
