Description

Technical Field

[0001] This utility model relates to the field of nanomaterials technology, specifically to a fine sieving device for preparing active ultrafine calcium carbonate. Background Technology

[0002] Calcium carbonate (CaCO3) is an inorganic compound, commonly known as limestone, stone powder, marble, etc. Calcium carbonate is neutral, basically insoluble in water, but soluble in hydrochloric acid. It is the main raw material for preparing activated ultrafine calcium carbonate. After the activated ultrafine calcium carbonate is prepared, it usually needs to be screened using a fine sieve device.

[0003] For example, a fine screening device for preparing activated ultrafine calcium carbonate, with announcement number "CN217120798U," uses a baffle plate to cover the vibrating screen body, thereby blocking small white solid particles floating in the air. This prevents a large number of white solid particles from floating in the air during the screening process, reducing the harm to workers' health. However, when cleaning is required, the baffle plate needs to be manually removed by the operator, and then reinstalled after cleaning, which consumes a lot of physical strength and increases labor costs. Furthermore, after screening, the operator needs to manually remove the unqualified activated ultrafine calcium carbonate piece by piece, which takes a long time to complete the discharge process, thus reducing work efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems of the following: when cleaning is required, operators need to manually remove the baffle plate, and after cleaning, it needs to be reinstalled, which consumes a lot of physical strength and increases manual labor. At the same time, after screening, the operator needs to manually remove the unqualified active ultrafine calcium carbonate piece by piece, which takes a long time to complete the discharge work and reduces work efficiency. Therefore, this invention proposes a fine screening device for the preparation of active ultrafine calcium carbonate.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fine sieving device for preparing active ultrafine calcium carbonate is designed, including a box and a discharge port. The discharge port is machined at the bottom of the box, and adjustment mechanisms are provided on both sides of the box. A discharge mechanism is provided at the rear of the box. A first motor is provided on the top of the box, and a turntable is fixedly connected to the end of the output shaft of the first motor. A first filter screen and a second filter screen are rotatably connected to the inner wall of the box through bearings. Multiple support legs are installed at the bottom of the box.

[0007] Preferably, the adjusting mechanism includes a bent plate, with a second motor fixedly connected to the bottom of each of the two bent plates. The inner side of each bent plate is fixedly connected to the housing. A threaded rod is fixedly connected to the end of the output shaft of each of the second motors. Both ends of the threaded rod are rotatably connected to the bent plate through bearings. The outer wall of each threaded rod is threadedly connected to a cover plate. A sliding seat is fixedly connected to the outer side of each cover plate. The sliding seat is slidably connected to the bent plate through a slot. The slot is machined on the inner side of the bent plate.

[0008] Preferably, two feed pipes are fixedly connected to both sides of the cover plate, and a first motor is fixedly connected to the middle of the cover plate.

[0009] Preferably, the discharge mechanism includes a fixed plate, the outer walls of both fixed plates are fixedly connected to the housing, a cylinder is fixedly connected above each fixed plate, the output end of each cylinder is fixedly connected to a crossbar, the inner wall of each crossbar is slidably connected to two vertical bars, both ends of each vertical bar are fixedly connected to a horizontal plate, the outer wall of each horizontal plate is fixedly connected to the housing, the outer wall of each crossbar is fixedly connected to a rack, and the rack meshes with two gears.

[0010] Preferably, the gear drive shaft is fixedly connected to the first filter screen and the second filter screen respectively.

[0011] The present invention proposes a fine sieving device for preparing active ultrafine calcium carbonate, which has the following advantages: through the cooperation of the housing and the adjustment mechanism, the output shaft of the second motor rotates to drive the threaded rod to rotate, thereby driving the cover plate to move. The movement of the cover plate drives the sliding seat to slide along the inner wall of the slot, so that when cleaning, the operator does not need to expend a lot of physical strength to move the cover plate, thereby saving manual labor.

[0012] Through the cooperation of the housing and the discharge mechanism, the cylinder output end moves, causing the crossbar to slide along the outer wall of the vertical bar. The movement of the crossbar causes the rack to move, and the movement of the rack causes the gear to rotate. Compared with the operator manually taking it out bit by bit, it takes less time, thus improving work efficiency. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] See attached document Figure 1-5 In this embodiment, a fine sieving device for preparing active ultrafine calcium carbonate includes a box body 1 and a discharge port 8. The discharge port 8 is machined at the bottom of the box body 1. Adjustment mechanisms 6 are provided on both sides of the box body 1. A discharge mechanism 9 is provided at the rear of the box body 1. A first motor 5 is provided on the top of the box body 1. Both the first motor 5 and the second motor 602 are servo motors. A turntable 3 is fixedly connected to the end of the output shaft of the first motor 5. A first filter screen 7 and a second filter screen 2 are rotatably connected to the inner wall of the box body 1 through bearings. The mesh size of the first filter screen 7 and the second filter screen 2 can be selected according to actual needs to meet the working requirements. Multiple support legs are installed at the bottom of the box body 1.

[0021] The adjustment mechanism 6 includes two bent plates 601. A second motor 602 is fixedly connected to the bottom of each bent plate 601. The second motors 602 are identical servo motors and can rotate synchronously. The inner sides of the bent plates 601 are fixedly connected to the housing 1. A threaded rod 603 is fixedly connected to the end of the output shaft of each second motor 602. Both ends of the threaded rod 603 are rotatably connected to the bent plates 601 via bearings. The outer walls of the threaded rods 603 are threadedly connected to the cover plate 604. A sliding seat 605 is fixedly connected to the outer side of the cover plate 604. The sliding seat 605 is slidably connected to the bent plates 601 via slots 606. The slots 606 are machined on the inner side of the bent plates 601. Two feed pipes 4 are fixedly connected to both sides of the cover plate 604. A first motor 5 is fixedly connected to the middle of the cover plate 604. The rotation of the output shaft of the second motor 602 drives the threaded rod 603 to rotate, thereby moving the cover plate 604. The movement of the cover plate 604 causes the sliding seat 605 to slide along the inner wall of the slot 606.

[0022] The discharge mechanism 9 includes a fixed plate 901. The outer walls of both fixed plates 901 are fixedly connected to the housing 1.

The rack 906 meshes with two gears 907. The drive shafts of the gears 907 are fixedly connected to the first filter screen 7 and the second filter screen 2, respectively. The movement of the output end of the cylinder 902 causes the horizontal bar 903 to slide along the outer wall of the vertical bar 904. The movement of the horizontal bar 903 causes the rack 906 to move. The movement of the rack 906 causes the gears 907 to rotate.

[0023] Working principle:

[0024] When using a fine sieving device to screen the prepared activated ultrafine calcium carbonate:

[0025] The operator adds the activated ultrafine calcium carbonate to be screened into the box 1 through the feed pipes 4 on both sides. The activated ultrafine calcium carbonate falls onto the turntable 3. Then the first motor 5 is started. The output shaft of the first motor 5 rotates and drives the turntable 3 to rotate, so that the activated ultrafine calcium carbonate is evenly distributed on the first filter screen 7 through the through holes on the turntable 3.

[0026] The diameter of the filter holes on the first filter screen 7 is larger than that on the second filter screen 2. Qualified activated ultrafine calcium carbonate passes through the first filter screen 7 and the second filter screen 2 in sequence, and is finally discharged from the outlet 8. The activated ultrafine calcium carbonate can be finely screened by passing through the second filter screen 7. After screening, the operator starts the lower cylinder 902. The output end of the cylinder 902 moves and drives the lower horizontal bar 903 to slide along the outer wall of the vertical bar 904. The movement of the lower horizontal bar 903 drives the lower rack 906 to move. The movement of the rack 906 drives the gear 907 to rotate. The rotation of the gear 907 drives the second filter screen 2 to rotate towards the outlet 8, so that the unqualified activated ultrafine calcium carbonate on the second filter screen 2 is discharged from the outlet 8. After the activated ultrafine calcium carbonate on the second filter screen 2 is discharged, the upper cylinder 901 is started to discharge the activated ultrafine calcium carbonate on the first filter screen 7. Compared with the operator manually removing it, it takes less time.

[0027] After all the activated ultrafine calcium carbonate is discharged, the first filter screen 7 and the second filter screen 2 are reset by controlling cylinder 902 for easy reuse. The operator starts the second motor 602, and the output shaft of the second motor 602 rotates forward, driving the threaded rod 603 to rotate, thereby moving the cover plate 604. The movement of the cover plate 604 causes the sliding seat 605 to slide upward along the inner wall of the slot 606. When the cover plate 604 is moved to a position that is easy for the operator to clean, the power of the second motor 602 is turned off. This allows the operator to move the cover plate 604 without expending much physical effort. The box 1, the first filter screen 7 and the second filter screen 2 are then rinsed using an external high-pressure water gun. The rinsed waste and wastewater are discharged from the discharge port 8. Finally, the cover plate 604 is reset by controlling the second motor 602 for easy reuse.

[0028] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
