Description

Technical Field

[0001] The utility model relates to the technical field of calcite powder processing, in particular to calcite powder processing equipment based on airflow screening technology. Background Art

[0002] Calcite is a calcium carbonate mineral. Calcite is a widely distributed mineral and the most common type of natural calcium carbonate. The crystal shapes of calcite vary. Their aggregates can be clusters of crystals, or granular, massive, fibrous, stalactitic, earthy, etc. Knocking on calcite can produce many square fragments, hence the name calcite.

[0003] Airflow screening is a high-precision screening equipment that screens fine powders with a mesh. It is widely used in chemical, pharmaceutical, food, papermaking, metallurgy, building materials, rubber, machinery and other industries. Before further processing, calcite powder needs to be screened. At present, most feed pipes and screening machines are directly connected. As a result, in the process of adding calcite powder to the screening machine, some calcite powder will float out through the screening machine feed pipe under the action of airflow, causing air pollution. For this reason, a calcite powder processing equipment based on airflow screening technology is proposed. Utility Model Content

[0027] like Figures 1 to 5 As shown, the calcite powder processing equipment based on the airflow screening technology includes: a screening machine 1, a support frame 101 and a feed pipe 102 are respectively provided on the outside of the screening machine 1, and a rotating shaft 103 is provided inside the feed pipe 102; a dustproof component is arranged on the outside of the feed pipe 102, for blocking the calcite powder, and the dustproof component includes a shielding component 2 and a feeding component 4, and the shielding component 2 cooperates with the feeding component 4 to block the calcite powder inside the feed pipe 102; a dust collection component 3 is arranged on the outside of the shielding component 2, for collecting the calcite powder floating inside the shielding component 2. Specifically, when screening the calcite powder, the calcite powder to be screened is first passed through the shielding component 2 to the screening machine. The calcite powder is added to the inside of the machine 1 so that the screening machine 1 can screen the calcite powder. In the process of adding calcite powder to the inside of the shielding component 2, the powder entering the screening machine 1 is blocked by the feeding component 4 to prevent the powder inside the screening machine 1 from floating out and causing air pollution. While blocking the calcite powder, the calcite powder floating inside the shielding component 2 is collected by the dust collection component 3 to prevent the calcite powder inside the shielding component 2 from escaping, further ensuring stability during use. An auger is provided on the outside of the rotating shaft 103 to transport the calcite powder to be screened during use. An airflow screening mechanism is provided inside the screening machine 1. The screening machine 1 is a prior art and will not be explained in detail here.

[0028] like Figures 1 to 5 As shown, the shielding assembly 2 includes a fixed cover 201, a collecting hopper 202 and a connecting pipe 203. The connecting pipe 203 is arranged on the outside of the feed pipe 102, and the connecting pipe 203 is connected to the feed pipe 102. The collecting hopper 202 is arranged at one end of the connecting pipe 203, and the collecting hopper 202 is funnel-shaped. The fixed cover 201 is arranged at one end of the collecting hopper 202, and the baffle 204 is engaged with the gear set. Specifically, when in use, the fixed cover 201 cooperates with the collecting hopper 202 to guide the calcite powder that needs to be screened to ensure that the calcite powder can enter the inside of the feed pipe 102 through the connecting pipe 203. At the same time, the fixed cover 201 can block the dust raised by the addition of calcite powder to prevent the operator from inhaling calcite powder.

[0029] like Figures 1 to 5As shown, the feeding assembly 4 includes a gear set, a dust cover 402 and a rotating roller 401. There are multiple rotating rollers 401, and isolation plates are provided on the outside of the rotating rollers 401. There are multiple isolation plates, and the rotating rollers 401 rotate inside the connecting pipe 203. One end of the rotating rollers 401 is provided with a first gear 403, and the dust cover 402 is arranged on the outside of the gear set. Specifically, the rotating rollers 401 cooperate with the isolation plates to transport the calcite powder accumulated inside the collecting bucket 202. There are gaps between adjacent partitions, and the calcite powder that needs to be screened is transported through the gaps between adjacent partitions.

[0030] like Figures 1 to 5 As shown, the gear set includes a fixing frame 405, which is connected to the connecting pipe 203. A second gear 404 is provided on the outside of the fixing frame 405. There are multiple second gears 404, which are meshed with each other, and the second gears 404 are meshed with the first gear 403. Specifically, the number of second gears 404 is an even number, ensuring that the first gear 403 can rotate in the opposite direction when in use. When in use, the cooperation between the second gear 404 and the first gear 403 ensures that the rotating roller 401 and the isolation plate can rotate synchronously, avoiding the isolation plate outside the rotating roller 401 from rotating. The staggered rotation causes calcite powder to float out. A motor is provided on the outside of the dust cover 402, and the motor is connected to any one of the first gears 403. When adding calcite powder, the motor first drives the cooperation of the second gear 404, thereby driving the first gears 403 on both sides to rotate in the opposite direction. During the reverse rotation of the first gear 403, the calcite powder is gradually added through the isolation plate on the outside of the rotating roller 401 to prevent the calcite powder inside the connecting tube 203 from escaping. At the same time, the adding speed of the calcite powder is controlled to avoid blockage caused by the accumulation of calcite powder.

[0031] like Figures 1 to 5As shown, the dust collection component 3 includes a fan 301 and an air outlet strip 303. The fan 301 is arranged on the outside of the fixed cover 201. An air outlet pipe 302 and a connecting pipe 304 are respectively provided on the outside of the fan 301. There are multiple air outlet strips 303, and multiple air outlet strips 303 are arranged inside the fixed cover 201. An air guide pipe is provided between the air outlet strip 303 and the air outlet pipe 302. A fixed shell 305 is provided at one end of the connecting pipe 304. The fixed shell 305 is connected to the fixed cover 201, and The fixed shell 305 is connected to the fixed cover 201, and a filter element 306 is provided inside the fixed shell 305. An air outlet is provided on one side of the opposite side of the air outlet strip 303, and the air outlet is connected to the air guide pipe. Specifically, the fan 301 is a prior art and will not be described in detail here. The filter element 306 blocks the collected calcite powder when in use to prevent the calcite powder from entering the fan 301 through the connecting pipe 304. The fixed shell 305 is connected to the fixed cover 201. The filter element 306 is connected by threads or snaps, which makes it easy to quickly replace the filter element 306 when in use. The air outlet is in the shape of a long strip. The air blown by the fan 301 enters the interior of the air outlet strip 303 through the air outlet pipe 302 and the air guide pipe. The air entering the interior of the air outlet strip 303 is discharged through the air outlet hole, thereby forming an air curtain to block the calcite powder. When in use, the fan 301 first collects the calcite powder raised by the interior of the fixed cover 201 through the connecting pipe 304 and the fixed shell 305, and at the same time blocks the calcite powder through the filter element 306 during collection. When the fan 301 collects the calcite powder raised by the interior of the fixed cover 201, since the air enters from the opening side of the fixed cover 201, the air drives the air curtain blown by the air outlet strip 303 to bend toward the interior of the fixed cover 201 when entering the fixed cover 201, thereby preventing the calcite powder from escaping outward through the opening of the fixed cover 201 when in use.

[0032] like Figures 1 to 5 As shown, a baffle 204 is provided inside the connecting tube 203. There are multiple baffles 204, and the baffles 204 are arranged on both sides of the rotating roller 401. Specifically, the baffles 204 block the gap between the isolation plate and the connecting tube 203, further preventing calcite powder from escaping from between the connecting tube 203 and the isolation plate.
