Description

Technical Field

[0001] The utility model relates to the technical field of nano calcium carbonate, in particular to an automatic screening device for a bin for producing nano calcium carbonate. Background Technique

[0002] Nano calcium carbonate is a nano material with relatively low cost. According to its characteristics, it has obvious advantages in aspects such as reinforcement, transparency, dispersibility, thixotropy and leveling property, so that nano calcium carbonate has a relatively broad market and application in the manufacture of plastic products.

[0003] The patent with the patent announcement number: CN218309549U discloses a production and preparation device for nano calcium carbonate, including a bottom plate. The top of the bottom plate is fixedly connected with a first side plate and a second side plate. Between the first side plate and the second side plate, there is a cleaning box for placing ore blocks to be cleaned. Inside the cleaning box, there are two turning rods for turning the ore blocks. Inside the cleaning box, there is a set of turning mechanisms for driving the two turning rods to turn the ore blocks. Inside the cleaning box, there are a plurality of filter holes for sediment to pass through; The tops of the first side plate and the second side plate are respectively fixedly connected with a first mounting plate and a second mounting plate. Between the first mounting plate and the second mounting plate, a plurality of rotating shafts are rotatably connected. On the circumferential surfaces of the plurality of rotating shafts, communicating blocks are fixedly connected. The bottoms of the plurality of communicating blocks are fixedly connected with high-pressure nozzles for cleaning the ore blocks; Between the first side plate and the second side plate, there is a set of jolting mechanisms for driving the cleaning box to jolt. On one side of the second mounting plate, there is a set of gear connection mechanisms. The jolting mechanism drives the plurality of high-pressure nozzles to adjust the cleaning angle through the gear connection mechanism. The above patent has the following deficiencies: Although this patent can produce nano calcium carbonate, when the nano calcium carbonate is produced, there will be some hard lumps sticking together. If these hard lumps are screened manually, it will not only be time-consuming and laborious, but also increase the labor cost of the factory. In view of this, we propose an automatic screening device for a bin for producing nano calcium carbonate. Summary of the Utility Model

[0023] Embodiment 1

[0024] As Figures 1-4As shown in the figure, an automatic screening device for a bunker used in the production of nano-calcium carbonate includes a base 1. A back plate 2 is fixedly connected to the top of the base 1, and a vibrating sieve mechanism 3 is arranged on the front surface of the back plate 2. The vibrating sieve mechanism 3 includes a chute 31, a slider 32, a first box body 33, a filter plate 34, a slideway 35, a motor 36, a transmission shaft 37, a movable rod 38, a push rod 39, a fixed block 310, and a spring 311. The chute 31 is opened on the front surface of the back plate 2, the slider 32 is slidably connected to the inside of the chute 31, the first box body 33 is fixedly connected to the front surface of the slider 32, the filter plate 34 is fixedly connected to the inside of the first box body 33, and the filter plate 34 is inclined to be higher on the left and lower on the right. The slideway 35 is arranged on the bottom inner wall of the first box body 33, and the slideway 35 is inclined to be lower on the left and higher on the right. The movement of the slider 32 is limited by setting the chute 31. The motor 36 is fixedly connected to the top of the base 1 through a bracket. The front output end of the motor 36 is fixedly connected to the left end of the movable rod 38 through the transmission shaft 37. The transmission shaft 37 rotates through the back plate 2 by means of a bearing. The right end of the movable rod 38 is fixedly connected to the rear end of the push rod 39. The fixed block 310 is fixedly connected to the bottom of the first box body 33. The motor 36 is supported by setting the bracket. The right end of the slider 32 is fixedly connected to the left end of the spring 311, and the right end of the spring 311 is fixedly connected to the right inner wall of the chute 31.

[0025] During use, first pour the material to be screened into the inside of the first box body 33, and then start the motor 36 to drive the transmission shaft 37 to rotate clockwise. The transmission shaft 37 rotates clockwise to drive the movable rod 38 to rotate clockwise. The movable rod 38 rotates clockwise to drive the push rod 39 to revolve clockwise and push the fixed block 310 to the right during the rotation process. The fixed block 310 moves to the right to drive the first box body 33 to move to the right and compress the spring 311. Subsequently, the spring 311 rebounds to drive the first box body 33 to move to the left. Thus, the first box body 33 and the filter plate 34 move left and right, and the materials inside are vibrated and screened. Larger-sized materials will slide down through the filter plate 34 into the second box body 41, and smaller-sized materials will fall through the filter holes on the filter plate 34 onto the slideway 35 and finally slide down from the slideway 35 into the third box body 5.

[0026] Embodiment 2

[0027] As Figures 1-4As shown, a crushing mechanism 4 is provided on the top of the base 1. The crushing mechanism 4 includes a second box body 41 which is fixedly connected to the top of the base 1. Two horizontal shafts 42 are rotatably penetrated through the inside of the second box body 41 by bearings. A crushing roller 43 is fixedly connected to the middle parts of the two horizontal shafts 42. Gear 44 is fixedly connected to the front ends of the two horizontal shafts 42, and the two gears 44 are meshed with each other. The second box body 41 is provided to provide a supporting force for the horizontal shaft 42. A pulley 45 is fixedly connected to the middle part of the transmission shaft 37 and the rear end of the right horizontal shaft 42, and the two pulleys 45 are connected by a transmission belt. A third box body 5 is provided at the lower left corner of the first box body 33, and the second box body 41 is arranged at the lower right corner of the first box body 33.

[0028] During use, on the basis of Embodiment 1, when the transmission shaft 37 rotates, the right horizontal shaft 42 is driven to rotate by the pulley 45 and the transmission belt. The rotation of the right horizontal shaft 42 drives the left horizontal shaft 42 to rotate through the gear 44. Thus, the two horizontal shafts 42 rotate simultaneously, and drive the crushing roller 43 to rotate to crush the materials falling on the filter plate 34.
