Description

Technical Field

[0001] The utility model relates to the field of calcium carbonate screening, in particular to calcium carbonate grading and sorting equipment. Background Art

[0002] Calcium carbonate is an inorganic compound with the chemical formula of CaCO3. It is the main component of limestone, marble, etc. Calcium carbonate is usually white crystals, tasteless, and basically insoluble in water. During the processing of calcium carbonate, sorting equipment is needed to classify it, that is, to screen and classify calcium carbonate of different particle sizes.

[0003] According to the Chinese patent with publication number CN218854807U, a calcium carbonate grading and sorting device is disclosed. The sorting device has a small volume, which is convenient for feeding from the top. The setting of the chute makes the grade of the sorted calcium carbonate more accurate, which improves the practicality. By setting the inclined neck, the calcium carbonate material falling on the first sub-sieve plate is more dispersed and will not be concentrated. The dispersed calcium carbonate can fully contact with the surface of the first sub-sieve plate, so that the filtration efficiency is further improved.

[0004] In view of the above-mentioned disclosed patent content, two inclined sub-screen plates are provided to facilitate the classification and screening of calcium carbonate. However, after the calcium carbonate falls onto the sub-screen plate, although it can slide along the inclined direction of the sub-screen plate, part of the calcium carbonate will adhere to the sub-screen plate and will be difficult to slide, resulting in that part of the calcium carbonate is difficult to be screened. Over time, this part of the calcium carbonate may clog the screen plate, thereby affecting the subsequent screening effect of the sub-screen plate on calcium carbonate. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a calcium carbonate grading and sorting device to solve the technical problem of poor screening effect of calcium carbonate through a sieve plate.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a calcium carbonate grading and sorting equipment, including a device body, wherein a first screen, a second screen and a third screen are installed in sequence from left to right inside the device body, and two movable shafts are connected to the inside of the device body through bearings, and a driving motor is installed on the outer surface of the device body, and the output end of the driving motor is connected to a driving shaft extending to the inside of the device body, and one end of the driving shaft and one end of a movable shaft are connected to a sprocket, and one end of the other movable shaft is installed with two sprockets, and a chain is meshed between every two sprockets, and a flipping plate is provided at the top of the driving shaft and the tops of the two movable shafts.

[0007] By adopting the above technical solution, when calcium carbonate needs to be screened, the staff can start the drive motor, and the drive motor can drive the drive shaft to rotate, and then drive the sprocket connected thereto to rotate.

[0008] Furthermore, a material guide plate is installed between the first screen and the second screen and between the second screen and the third screen.

[0009] By adopting the above technical solution, the guide plate is arranged so that the calcium carbonate can slide into the second screen and the third screen, thereby the calcium carbonate can be screened.

[0010] Furthermore, a partition is provided at the bottom of the material guide plate, and three second collecting boxes are placed below the interior of the device body.

[0011] By adopting the above technical solution, the partition is set to prevent calcium carbonate of different particle sizes from falling into other second collection boxes, so that the calcium carbonate screened by the screen can only fall into the second collection box directly below.

[0012] Furthermore, a discharge port is provided at the lower side of one side of the device body, and a discharge plate extending to the inside of the discharge port is installed on one side of the third screen.

[0013] By adopting the above technical solution, after the calcium carbonate slides onto the discharge plate, the calcium carbonate can slide out through the discharge port and fall into the first collecting box.

[0014] Furthermore, a first collection box is provided below one side of the device body, and the first collection box is slidably connected to the device body.

[0015] By adopting the above technical solution, the first collecting box can collect calcium carbonate that has not been screened by the screen, and at the same time, the first collecting box is slidably connected to the device body to facilitate taking out the first collecting box.

[0016] Furthermore, a material blocking cover is installed inside the device body, and the top of the material turning plate is in contact with the material blocking cover.

[0017] By adopting the above technical solution, the material blocking cover can block the calcium carbonate and prevent the turning plate from lifting the calcium carbonate to other places.

[0018] Furthermore, the first screen, the second screen and the third screen are all in arc shape, and the mesh diameters of the first screen, the second screen and the third screen decrease successively.

[0019] By adopting the above technical solution, after the calcium carbonate is screened by the first screen, the calcium carbonate accumulated on the first screen will slide onto the second screen and be screened by the second screen.

[0020] Furthermore, a feed hopper is provided on one side of the top of the device body, and the feed hopper is located above the first screen.

[0021] By adopting the above technical solution, the setting of the feed hopper makes it easy to add calcium carbonate into the interior of the device body, and the added calcium carbonate can fall onto the first sieve.

[0022] Furthermore, a control panel is installed on the outer surface of the device body, and the control panel is electrically connected to the driving motor.

[0023] By adopting the above technical solution, it is convenient for the staff to start or shut down the drive motor through the control panel.

[0024] Furthermore, the outer wall of the material turning plate is smooth, and the top of the material guiding plate is smooth.

[0025] By adopting the above technical solution, calcium carbonate can smoothly slide onto the next screen through the guide plate, thereby improving the screening effect of calcium carbonate.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] The utility model is provided with a driving motor, a driving shaft, a sprocket, a chain, a movable shaft and a flipping plate. When calcium carbonate needs to be screened, a worker can start the driving motor, and the driving motor can drive the driving shaft to rotate slowly in the counterclockwise direction, and then drive the sprocket connected thereto to rotate, and then drive another sprocket to rotate through the chain, and then drive another sprocket to rotate through the chain, so that the two movable shafts and the driving shaft can rotate at the same time, and then drive the flipping plate to rotate, and the flipping plate located on the first screen can slowly flip the calcium carbonate and push the calcium carbonate on the first screen The calcium carbonate is then pushed onto the second screen by the flipping plate, and then flipped and screened by the flipping plate on the second screen. After screening, the calcium carbonate is sifted onto the third screen. In this way, the calcium carbonate is sifted in turn, thereby improving the screening effect of calcium carbonate and avoiding the accumulation of calcium carbonate on the screen and making it difficult to move, so that the calcium carbonate can slide onto the next screen for screening in an orderly manner, while avoiding the clogging of the screen by calcium carbonate, thereby improving the screening efficiency of calcium carbonate.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0034] The following describes an embodiment of the utility model based on its overall structure.

[0035] Embodiment 1:

After the calcium carbonate is screened by the first screen 4, the calcium carbonate accumulated on the first screen 4 will slide onto the second screen 5 and be screened by the second screen 5. A feed hopper 2 is provided on one side of the top of the device body 1, and the feed hopper 2 is located above the first screen 4. The setting of the feed hopper 2 is convenient for adding calcium carbonate into the inside of the device body 1, and the added calcium carbonate can fall onto the first screen 4. The inside of the device body 1 is also connected to two movable shafts 9 through bearings, and a drive motor 16 is installed on the outer surface of the device body 1. A control panel 19 is installed on the outer surface of the device body 1, and the control panel 19 is electrically connected to the drive motor 16, so that the staff can start or shut down the drive motor 16 through the control panel 19.

[0037] Specifically, the output end of the driving motor 16 is connected to a driving shaft 7 extending into the interior of the device body 1, and one end of the driving shaft 7 is connected to one end of a movable shaft 9 with a sprocket 17, and one end of the other movable shaft 9 is equipped with two sprockets 17, and a chain 18 is meshed and connected between every two sprockets 17.

When calcium carbonate needs to be screened, the staff can start the driving motor 16, and the driving motor 16 can drive the driving shaft 7 to rotate, and then drive the sprocket 17 connected thereto to rotate.

[0038] See also Figure 2-Figure 4 A material guide plate 3 is installed between the first sieve 4 and the second sieve 5 and between the second sieve 5 and the third sieve 6. The top of the material guide plate 3 is smooth. The material guide plate 3 is arranged so that calcium carbonate can slide into the second sieve 5 and the third sieve 6, so that the calcium carbonate can be screened. A partition 15 is arranged at the bottom of the material guide plate 3. Three second collecting boxes 14 are placed below the inside of the device body 1. The second collecting boxes 14 are slidably connected to the device body 1 to facilitate the removal of the second collecting boxes 14, so that the calcium carbonate collected in the second collecting boxes 14 can be cleaned. The three second collecting boxes 14 are respectively located directly below the first sieve 4, the second sieve 5 and the third sieve 6. The setting of the partition 15 prevents calcium carbonate of different particle sizes from falling into other second collecting boxes 14, so that the calcium carbonate screened by the sieve can only fall into the inside of the second collecting box 14 directly below.

[0039] See also Figure 1-Figure 4 A discharge port 12 is provided at the lower side of the device body 1, and a discharge plate 11 extending to the inside of the discharge port 12 is installed on one side of the third screen 6.

The setting of the material blocking cover 10 can block the calcium carbonate and prevent the material turning plate 8 from lifting the calcium carbonate to other places.

[0043] The working principle of the utility model is as follows: first, the staff can install the sorting equipment and connect the power supply, then add calcium carbonate into the device body 1 through the feed hopper 2, and then start the drive motor 16. The drive motor 16 can drive the drive shaft 7 to rotate slowly in the counterclockwise direction, and then drive the sprocket 17 connected thereto to rotate, and then drive another sprocket 17 to rotate through the chain 18, and then drive another sprocket 17 to rotate through the chain 18, so that the two movable shafts 9 and the drive shaft 7 can rotate at the same time, and then drive the flipping plate 8 to rotate, and the flipping plate 8 located on the first screen 4 can rotate. The calcium carbonate can be slowly flipped and pushed to move on the first screen 4, so that the first screen 4 can screen the calcium carbonate. As the flipping plate 8 continues to rotate, the flipping plate 8 can push the calcium carbonate that has not been screened and filtered by the first screen 4 onto the second screen 5, and then flip and screen it through the flipping plate on the second screen 5. After screening, it slides onto the third screen 6, and the calcium carbonate is screened in this way. The calcium carbonate that falls downward during the screening process will fall into the second collection box 14 below, and the calcium carbonate that has not been screened by the third screen 6 will slide into the first collection box 13 through the discharge plate 11.
