[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0020] like Figures 1 to 8As shown, a calcium carbonate processing batching device described in an embodiment of the present invention comprises: a mixing barrel 21; a side plate 3 fixedly connected to the top of the mixing barrel 21; a pillar 31 fixedly connected to the top of the side plate 3; a feeding barrel 32 fixedly connected to the top of the pillar 31; a crushing bin 33 connected to and fixed to the top of one end of the feeding barrel 32; a drop hopper 34 connected to and fixed to the bottom of the other end of the feeding barrel 32; a protective barrel 4 fixedly connected between the mixing barrel 21 and the feeding barrel 32; a flow control mechanism disposed in the protective barrel 4; the flow control mechanism comprises a weighing barrel 41, the bottom end of which is fixedly connected to a circular plate 42; four weighing sensors 43 are fixedly connected to the bottom of the circular plate 42, and the bottoms of the weighing sensors 43 are all fixedly connected to the top of the mixing barrel 21; the bottom of the weighing barrel 41 is connected through the mixing barrel 21, and A solenoid valve 44 is installed; two connecting plates 342 are symmetrically fixed on the side wall of the drop hopper 34, one end of the two connecting plates 342 is rotatably connected to a bidirectional ball screw 343 through a bearing, and the other end of the two connecting plates 342 is fixed to two guide rods 344; two blocking plates 341 are symmetrically threadedly connected to the bidirectional ball screw 343, one end of the blocking plates 341 is slidably connected to the two guide rods 344; a third motor 345 is fixed to one of the connecting plates 342, and the output shaft of the third motor 345 is fixed to one end of the bidirectional ball screw 343; the third motor 345 and the solenoid valve 44 are both electrically connected to the weighing sensor 43; the bottom end of the mixing barrel 21 is fixed to a mounting frame 2, and the bottom of the mounting frame 2 is fixed to a bottom plate 1.

[0021] Calcium carbonate usually needs to be weighed in advance when it is unloaded, but calcium carbonate is usually in the form of blocks or large particles. Large particles of calcium carbonate are prone to more or less, which may lead to inaccurate batching and inconvenience in quick weight balancing. Therefore, when unloading, the large particles of calcium carbonate are crushed into small particles through the crushing bin 33, and then fed through the spiral blade 321 to avoid large particles of calcium carbonate squeezing and damaging the edge of the spiral blade 321. After the calcium carbonate is mixed in the feeding barrel 32, the unloading is carried out. When the flow control mechanism provided by the present invention is used, the third motor 345 is turned on, and the third motor 345 drives the bidirectional ball screw 343 to rotate through the output shaft, and the bidirectional ball screw 343 drives the blocking plate 341 to move to both sides, and the calcium carbonate in the feeding barrel 32 passes through the drop hopper 3 4 falls into the weighing cylinder 41, at which time the weight of the calcium carbonate in the weighing cylinder 41 is monitored by the weighing sensor 43. When the monitored weight reaches 90% of the set value, the third motor 345 is controlled by the computer system. The third motor 345 drives the bidirectional ball screw 343 to rotate through the output shaft, and drives the blocking plate 341 to move toward the center to a gap of 2 cm through the bidirectional ball screw 343, and stops moving until the monitored weight reaches the set value. The bidirectional ball screw 343 drives the blocking plate 341 to move toward the center to a tightly closed state. The different state settings of the blocking plate 341 facilitate the control of the flow rate in the later stage of material feeding to prevent excessive flow from causing the weighing sensor 43 to fail to close in time when reaching the set value, making it inconvenient to control the amount of calcium carbonate, thereby realizing the function of controlling the amount of calcium carbonate during batching.

[0022] like Figure 3 and Figure 4 As shown, two rotating rods 333 are rotatably connected in the crushing bin 33 through bearings, and crushing rollers 331 are fixedly connected to the outer walls of the rotating rods 333.

[0023] The crushing roller 331 provided by the present invention is used to crush calcium carbonate when in use. By turning on the second motor 337, the second motor 337 drives the connected rotating rod 333 to rotate through the output shaft, and drives the connected circular gear 332 to rotate through the rotating rod 333. The circular gear 332 drives another circular gear 332 to rotate in the opposite direction, and the other circular gear 332 drives the connected rotating rod 333 to rotate in the opposite direction. The two rotating rods 333 drive the crushing roller 331 to rotate in opposite directions, thereby crushing the calcium carbonate.

[0024] like Figure 7 and Figure 8As shown, the top of the mixing barrel 21 is fixedly connected to a first motor 22, the output shaft of the first motor 22 is fixedly connected to a stirring rod 23, and a plurality of first stirring paddles 24 are fixedly connected to the stirring rod 23; the top of the stirring rod 23 is fixedly connected to a first bevel gear 232, and the top of the stirring rod 23 is rotatably connected to a second bevel gear 233, and the second bevel gear 233 is arranged above the first bevel gear 232 and is arranged in a reverse symmetrical manner; the bottom of the first bevel gear 232 is fixedly connected to a first connecting rod 235, and the top of the second bevel gear 233 is fixedly connected to a second connecting rod 2 36, the first connecting rod 235 and the second connecting rod 236 are rotatably connected to the gear box 231; the side wall of the gear box 231 is rotatably connected to the third connecting rod 237, one end of the third connecting rod 237 is fixedly connected to the third bevel gear 234, and the two ends of the third bevel gear 234 are respectively meshed with the first bevel gear 232 and the second bevel gear 233; the top end of the second connecting rod 236 is fixedly connected to the rotating frame 25, and the inner side walls of the rotating frame 25 are fixedly connected to three second stirring paddles 26, and the second stirring paddles 26 are staggered with the first stirring paddle 24.

[0025] The first stirring paddle 24 and the second stirring paddle 26 provided by the present invention are used to fully and quickly stir calcium carbonate and water when in use. By turning on the first motor 22, the first motor 22 drives the stirring rod 23 to rotate through the output shaft, and the stirring rod 23 drives the first stirring paddle 24 to rotate; when the stirring rod 23 rotates, it also drives the first bevel gear 232 to rotate, and the third bevel gear 234 is driven to rotate through the first bevel gear 232, and the second bevel gear 233 is driven to rotate through the third bevel gear 234. Since the first bevel gear 232 and the second bevel gear 233 are arranged in reverse symmetry, the second bevel gear 233 rotates in the opposite direction to the first bevel gear 232, and the second connecting rod 236 is driven to rotate through the second connecting rod 236, and the rotating frame 25 is driven to rotate. The second stirring paddle 26 is driven to rotate through the rotating frame 25, and the second stirring paddle 26 and the first stirring paddle 24 are staggered and rotate in different directions to fully stir the calcium carbonate, thereby realizing the function of quickly stirring and mixing ingredients.

[0026] like Figure 7 As shown, the bottoms of both ends of the rotating frame 25 are in contact with the bottom inner wall of the mixing barrel 21; scraper rods 29 are fixedly connected to the two outer walls of the rotating frame 25, and the scraper rods 29 are in contact with the inner wall of the mixing barrel 21; the bottom of the mixing barrel 21 is connected and fixedly connected with a discharge pipe 27, and a discharge valve 28 is installed on the discharge pipe 27.

[0027] The scraper rod 29 provided by the present invention is used to scrape off the calcium carbonate on the inner wall of the mixing barrel 21 when in use. After the ingredients are mixed, when it is necessary to discharge the ingredients, the first motor 22 is continued to be driven, thereby driving the rotating frame 25 to rotate, and the scraper rod 29 is driven to rotate through the rotating frame 25. The calcium carbonate on the inner wall of the mixing barrel 21 is scraped off by the scraper rod 29, and the calcium carbonate on the inner wall of the bottom of the mixing barrel 21 is scraped off through the bottom of the rotating frame 25, thereby completing the cleaning of the mixing barrel 21.

[0028] like Figure 4 As shown, a driving motor 322 is fixedly connected to one end of the feeding cylinder 32 close to the crushing bin 33, and an output shaft of the driving motor 322 is rotatably connected to the feeding cylinder 32 through a bearing, and a spiral blade 321 is fixedly connected to the output shaft of the driving motor 322 through a cross bar.

[0029] When the spiral blade 321 provided by the present invention is in use, the driving motor 322 is turned on to drive the spiral blade 321 to rotate, and the calcium carbonate in the feeding barrel 32 is squeezed and transported by the spiral blade 321. During the extrusion process, small particles of calcium carbonate continue to be crushed, and different particles of calcium carbonate are mixed before feeding.

[0030] like Figure 1 to Figure 2 As shown, a water tank 5 is fixedly connected to the base plate 1, a water inlet pipe 51 is connected and fixedly connected to the top of the mixing barrel 21, and one end of the water inlet pipe 51 away from the mixing barrel 21 is connected and fixedly connected to the water tank 5, a water pump 52 is fixedly connected to the water tank 5, and the water pump 52 is installed at one end of the water inlet pipe 51; a flow meter 53 is installed on the water inlet pipe 51, and the flow meter 53 is electrically connected to the water pump 52.

[0031] The flow meter 53 provided by the present invention is used to control the water output when in use. When mixing ingredients, the water pump 52 is turned on, and the water pump 52 transports the water in the water tank 5 to the mixing barrel 21 through the water inlet pipe 51. The water flow is monitored by the flow meter 53. When the water flow reaches the set value, the water pump 52 is controlled to be closed through the flow meter 53 to stop water delivery.

[0032] like Figure 3 As shown, a sealing plate 334 is slidably connected to the top of the crushing bin 33; a pull block 338 is fixedly connected to one end of the sealing plate 334 that passes through the crushing bin 33, and buckles 335 are provided on both sides of the pull block 338, and the buckles 335 are rotatably connected to the crushing bin 33 through pin shafts, and two clamping columns 336 are fixed to the crushing bin 33, and the clamping columns 336 are matched with the buckles 335.

[0033] The sealing plate 334 provided by the present invention is used to seal dust and prevent dust from flying when in use. When calcium carbonate is crushed by the crushing roller 331, dust is generated, so it is necessary to push the pulling block 338 to push the sealing plate 334 to one end of the crushing bin 33, and then rotate the two buckles 335 to clamp the two buckles 335 on the two clamping columns 336 to achieve the sealing of the crushing bin 33.

[0034] like Figure 6 As shown, four limiting columns 45 are fixedly connected to the outer side wall of the top end of the weighing cylinder 41, and four limiting grooves are opened on the inner wall of the protective cylinder 4, and the limiting columns 45 slide in the limiting grooves.

[0035] When the limiting column 45 provided by the present invention is in use, calcium carbonate falls into the weighing cylinder 41, and the weighing cylinder 41 will slide. During the sliding process of the weighing cylinder 41, the weighing cylinder 41 drives the limiting column 45 to slide in the limiting groove, and the limiting column 45 limits the weighing cylinder 41 in the vertical direction.

[0036] Working principle: by turning on the second motor 337, the second motor 337 drives the connected rotating rod 333 to rotate through the output shaft, and drives the connected circular gear 332 to rotate through the rotating rod 333, and the circular gear 332 drives another circular gear 332 to rotate in the opposite direction, and the other circular gear 332 drives the connected rotating rod 333 to rotate in the opposite direction, and the two rotating rods 333 drive the crushing roller 331 to rotate in opposite directions, so as to crush the calcium carbonate; the calcium carbonate in the feeding cylinder 32 is squeezed and transported through the spiral blade 321; by turning on the third motor 345, the third motor 345 drives the bidirectional ball screw 343 to rotate through the output shaft, and drives the sealing plate 341 to move to both sides through the bidirectional ball screw 343, and the calcium carbonate in the feeding cylinder 32 falls into the weighing cylinder 41 through the drop hopper 34, and the weight of the calcium carbonate in the weighing cylinder 41 is monitored by the weighing sensor 43 at this time, and the weight to be monitored reaches the set value When the weight reaches 90%, the third motor 345 is controlled by the computer system. The third motor 345 drives the bidirectional ball screw 343 to rotate through the output shaft, and drives the blocking plate 341 to move toward the center to a gap of 2 cm through the bidirectional ball screw 343, and stops moving until the monitored weight reaches the set value. The bidirectional ball screw 343 drives the blocking plate 341 to move toward the center to a closed state. The different state settings of the blocking plate 341 facilitate the control of the flow rate in the later stage of material feeding to prevent excessive flow, which will cause the weighing sensor 43 to fail to close in time when it reaches the set value, making it inconvenient to control the amount of calcium carbonate, thereby realizing the function of controlling the amount of calcium carbonate during batching; during batching, by turning on the water pump 52, the water pump 52 transports the water in the water tank 5 to the mixing barrel 21 through the water inlet pipe 51, and the water flow is monitored by the flow meter 53. When the water flow reaches the set value, the water pump 52 is controlled to close through the flow meter 53 to stop water delivery; By turning on the first motor 22, the first motor 22 drives the stirring rod 23 to rotate through the output shaft, and the stirring rod 23 drives the first stirring paddle 24 to rotate; when the stirring rod 23 rotates, it also drives the first bevel gear 232 to rotate, and the third bevel gear 234 is driven to rotate through the first bevel gear 232, and the second bevel gear 233 is driven to rotate through the third bevel gear 234. Since the first bevel gear 232 and the second bevel gear 233 are arranged in reverse symmetry, the second bevel gear 233 rotates in the opposite direction to the first bevel gear 232, and the second connecting rod 236 is driven to rotate through the second bevel gear 233. The rotating frame 25 is driven to rotate by the second connecting rod 236, and the second stirring paddle 26 is driven to rotate by the rotating frame 25. The second stirring paddle 26 rotates in different directions staggered from the first stirring paddle 24 to fully stir the calcium carbonate, thereby realizing the function of quickly stirring and mixing the ingredients; after the ingredients are completed, when it is necessary to discharge the materials, the first motor 22 is continued to be driven to drive the rotating frame 25 to rotate, and the scraper rod 29 is driven to rotate by the rotating frame 25, and the calcium carbonate on the inner wall of the mixing barrel 21 is scraped off by the scraper rod 29, and the calcium carbonate on the inner wall of the bottom of the mixing barrel 21 is scraped off through the bottom of the rotating frame 25, thereby completing the cleaning of the mixing barrel 21.
