Description

Technical Field

[0001] The utility model relates to the technical field of limestone powder filtering, in particular to a filtering device used in a limestone powder bin. Background Art

[0002] It is found in daily production that limestone powder may be mixed with various debris, such as iron sheets, wood strips, cloth strips, etc. During the transportation of limestone powder, these debris may cause blockage or even damage to the unloading frequency conversion air lock and spiral weighing feeder, thus affecting the preparation process of limestone powder slurry.

[0003] The existing patent CN202120653845.6 discloses a filtering device for limestone powder silo, which relates to the technical field of debris filtering. In the desulfurization process using limestone as a desulfurization absorbent, the limestone powder may be mixed with iron sheets, wood strips, cloth strips and other debris. The debris enters the corresponding mechanical equipment along with the limestone powder, which may cause the equipment to be blocked or even damaged, and have an adverse effect on the preparation process of the limestone slurry. The present application includes a filter cartridge for installation at the discharge port of the limestone powder silo and a filter element arranged in the filter cartridge;

[0004] In the actual implementation process of the above patent, larger impurities are blocked by multiple magnet bars, and iron filings can be adsorbed at the same time. However, the actual implementation requires the removal of impurities and iron filings, which is cumbersome and requires manual operation, thus affecting the operating efficiency and further affecting the filtration efficiency. Therefore, we propose a filtering device for a limestone powder silo. Utility Model Content

[0005] The purpose of the utility model is to provide a filtering device for limestone powder silo, which solves the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filtering device for a limestone powder silo, comprising a first cylinder, a second cylinder is arranged on the lower side of the first cylinder, a side wall of the first cylinder is connected to a first servo motor, the outer end of the transmission shaft of the first servo motor is fixedly connected to a rotating block, both side walls of the rotating block are connected to connecting rods, the outer ends of the connecting rods are fixedly connected to a ring, a plurality of evenly distributed electromagnet rods are fixed to the inner wall of the ring, one of the rings is arranged between the first cylinder and the second cylinder, the other side wall of the first cylinder is fixedly connected to a sleeve, the tail end of the sleeve is plugged into a movable column, and the tail end of the movable column is fixedly connected to the outer wall of the second cylinder.

[0007] By adopting the above technical scheme, the movable column is telescoped and lifted in the sleeve, thereby driving the second cylinder to lift and lower, thereby pressing the corresponding ring, and then introducing limestone powder into the first cylinder, so that the limestone powder will pass through the ring, so that the electromagnet rod in the ring can block and filter larger impurities, and the electromagnet rod can adsorb iron filings. When the filtered impurities and iron filings need to be cleaned, the movable column is used to drive the second cylinder to descend, and then the first servo motor is started to drive the rotating block to rotate, so that another ring enters between the first cylinder and the second cylinder, and then the second cylinder is closed again to convey the material for filtration, and at the same time, the iron filings and impurities in the ring rotated to the outside can be cleaned, thereby improving the convenience and efficiency of operation.

[0008] As a preferred embodiment of the utility model, a limiting groove is provided on one side wall of the first cylinder, an adaptive limiting slider is inserted into the inner cavity of the limiting groove, an electric push rod is fixedly connected to the bottom of the limiting slider, the tail end of the electric push rod is fixedly connected to the bottom of the inner cavity of the limiting groove, and the outer wall of the limiting slider is fixedly connected to the first servo motor through a connecting block.

[0009] By adopting the above technical solution, before the first servo motor drives the rotating block to rotate, the electric push rod is started to drive the limit slider to descend, so that the rotating block drives the ring to descend, thereby preventing impurities inside the ring from being scraped off by the bottom of the first cylinder when the ring rotates.

[0010] As a preferred embodiment of the present invention, second servo motors are embedded in both side walls of the rotating block, and the outer end of the transmission shaft of the second servo motor is fixedly connected to the corresponding connecting rod end.

[0011] By adopting the above technical solution, when the ring containing impurities and iron filings rotates to the outside, the corresponding second servo motor is started to flip the ring, so that the impurities are poured out, and at the same time the corresponding electromagnet rod is powered off, so that the iron filings will automatically fall off, thereby improving the convenience of the cleaning operation.

[0012] As a preferred embodiment of the utility model, a third servo motor is fixed to the top of the inner cavity of the sleeve, and a screw is fixedly connected to the outer end of the transmission shaft of the third servo motor. The outer end of the screw is inserted into a threaded hole opened at the end of the movable column and the threads are engaged. A stable bearing is mounted on one side of the outer wall of the screw, and the outer wall of the stable bearing is fixedly connected to the inner wall of the sleeve through a short rod.

[0013] By adopting the above technical solution, in actual use, starting the third servo motor can drive the screw to rotate, thereby driving the movable column to move, thereby driving the second cylinder to move, and then driving the first cylinder and the second cylinder to close and separate.

[0014] As a preferred embodiment of the utility model, matching rubber rings are fixed to the top and bottom of the circular ring.

[0015] By adopting the above technical solution and setting the rubber ring, the compression and sealing effect can be improved when the ring is compressed.

[0016] As a preferred embodiment of the present utility model, the top of the first cylinder and the tail end of the second cylinder are both fixedly connected with a cone cylinder.

[0017] By adopting the above technical solution and setting the cone, the feeding and discharging can be centralized.

[0018] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0019] The filtering device for limestone powder bin of the technical solution of the present application can drive the movable column to descend through the third servo motor, so that the second cylinder can descend, and then the first servo motor can drive the rotating block to rotate, so that the two rings can change positions, so that the filtered larger impurities and adsorbed iron filings can be quickly replaced, so that the cleaning of larger impurities and filtering can be carried out simultaneously, which improves the operating efficiency, and then improves the efficiency of limestone powder filtering, and the operation is convenient;

[0020] The second servo motor can drive the ring to flip, so that larger impurities blocked on the surface of the electromagnet plate can fall down. At the same time, cutting off the power to the electromagnet plate can make the adsorbed iron filings quickly separate from the electromagnet rod, thereby further improving the efficiency of removing impurities and iron filings.
