[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model provides Figure 1-Figure 8 The calcium carbonate powder efficient screening device shown in the figure comprises a screening box 1 with a feed port at the top, a feed discharge pipe 10 is connected to the bottom of the screening box 1, and a blower mechanism 2 and a screening mechanism 6 are arranged on the screening box 1, a first row hopper 3 and a second row hopper 8 are arranged on both sides of the screening box 1, and gates are inserted on the first row hopper 3 and the second row hopper 8 to facilitate the opening and closing of the first row hopper 3 and the second row hopper 8, and a first discharge pipe 4 and a second discharge pipe 7 that are interconnected are arranged on one side of the screening box 1, and a collecting box 9 is arranged below the second discharge pipe 7;

[0028] An adjusting mechanism 5 is also provided on one side of the screening box 1, and the adjusting mechanism 5 includes a lifting frame 57 and a base frame 51 fixed to the bottom of one side of the screening box 1, and a power component for driving the lifting frame 57 to rise and fall is also provided between the base frame 51 and the screening box 1, and the lifting frame 57 has a slot cavity for placing the collecting box 9, and the lifting frame 57 is also inserted with a baffle 58 for limiting the collecting box 9.

[0029] Specifically, the power component includes two fixed plates 52 fixed on one side of the screening box 1, and a first motor 53 installed on the top of one of the fixed plates 52, a screw rod 55 is rotatably installed between one of the fixed plates 52 and the base frame 51, a light rod 56 is connected between the other fixed plate 52 and the base frame 51, and connecting plates 54 and sleeves are fixed on both sides of the lifting frame 57, and the connecting plates 54 are sleeved on the screw rod 55, and the sleeve is slidably sleeved on the light rod 56, and the first motor 53 is used to drive the screw rod 55 to rotate.

[0030] When screening calcium carbonate powder, first add the calcium carbonate powder into the screening box 1 from the feed port, then screen the calcium carbonate powder in multiple stages through the screening mechanism 6, so that unqualified calcium carbonate powder is discharged from the first row hopper 3 and the second row hopper 8 respectively, and qualified calcium carbonate powder is discharged from the discharge pipe 10, thereby completing the screening of calcium carbonate powder;

[0031] During the screening process, the fine powder floating in the screening process of the calcium carbonate powder can be blown into the first discharge pipe 4 and the second discharge pipe 7 through the blower mechanism 2, and then the fine powder in the first discharge pipe 4 falls into the second discharge pipe 7, and is discharged into the collection box 9 together with the fine powder in the second discharge pipe 7, thereby realizing the collection of the fine powder;

[0032] After the fine powder is collected, when the collecting box 9 needs to be cleaned, the first motor 53 can be used to drive the screw rod 55 to rotate, so that the screw rod 55 drives the lifting frame 57 to descend through the connecting plate 54. At this time, the lifting frame 57 drives the collecting box 9 to descend synchronously, so that the collecting box 9 is away from the second discharge pipe 7 until the collecting box 9 is lowered onto the bottom frame 51, and then the baffle 58 is pulled out from the lifting frame 57, and the collecting box 9 is moved down from the lifting frame 57 to pour out the collected calcium carbonate fine powder, so as to facilitate the recycling of the calcium carbonate fine powder and clean it. After processing, the collecting box 9 can be installed on the lifting frame 57, and the collecting box 9 can be limited by the baffle 58, and then the first motor 53 can be used to drive the screw rod 55 to rotate in the opposite direction, so that the screw rod 55 can drive the lifting frame 57 to rise through the connecting plate 54, so as to drive the collecting box 9 to rise to the bottom of the second discharge pipe 7, so as to facilitate the subsequent use of the collecting box 9, thereby realizing the lifting and lowering adjustment of the collecting box 9, making it easier to remove the collecting box 9 filled with fine powder, greatly reducing the labor intensity of workers, and helping to improve the screening efficiency of calcium carbonate powder.

[0033] Regarding how to filter the above, Figure 5-Figure 8 As shown:

[0034] The screening mechanism 6 includes an upper screen plate 64, a lower screen plate 63 and two shaft rods 62 arranged inside the screening box 1. The upper screen plate 64, the lower screen plate 63 and the two shaft rods 62 are distributed at intervals, and the bottoms of the upper screen plate 64 and the lower screen plate 63 are connected to the inner wall of the screening box 1 with springs 65. Cams 66 are installed in the middle of the two shaft rods 62, and the convex ends of the two cams 66 are in contact with the bottoms of the upper screen plate 64 and the lower screen plate 63 respectively. One end of the two shaft rods 62 extends to the outside of the screening box 1 and is connected with a transmission belt. A second motor 61 is also fixed to one side of the screening box 1, and the main shaft of the second motor 61 is connected to the end of one of the shaft rods 62. The first row hopper 3 corresponds to the upper screen plate 64, and the second row hopper 8 corresponds to the lower screen plate 63.

[0035] When screening calcium carbonate powder, calcium carbonate powder is added into the screening box 1 from the feed port, and then the two shafts 62 are driven to rotate by the second motor 61 and the transmission belt. At this time, the two shafts 62 simultaneously drive the cams 66 thereon to rotate, so that the two cams 66 continuously touch the upper sieve plate 64 and the lower sieve plate 63 respectively, and then the upper sieve plate 64 and the lower sieve plate 63 vibrate under the action of the spring 65. When the calcium carbonate powder falls on the upper sieve plate 64, the calcium carbonate powder is screened by the vibration of the upper sieve plate 64, so that large particles of calcium carbonate powder are discharged through the first row hopper 3, and smaller calcium carbonate powder falls on the lower sieve plate 63 through the upper sieve plate 64. At this time, the calcium carbonate powder is screened again by the vibration of the lower sieve plate 63, so that the larger particles of powder mixed in the calcium carbonate powder are discharged through the second row hopper 8, and the qualified calcium carbonate powder falls to the bottom of the screening box 1 until it is discharged through the discharge pipe 10, thereby realizing multi-stage screening of calcium carbonate powder and improving the screening effect of calcium carbonate powder.

[0036] Regarding the above-mentioned method of blowing and sieving fine powder, Figure 1-Figure 8 As shown:

[0037] The blowing mechanism 2 includes a fan 21 fixed on one side of the screening box 1, and a first blowing pipe 25 and a second blowing pipe 26 installed on the inner wall of the screening box 1, the first blowing pipe 25 is above the upper sieve plate 64, and the second blowing pipe 26 is above the lower sieve plate 63. A connecting valve 22 is connected to one side of the fan 21, and a first branch pipe 23 is connected between one end of the connecting valve 22 and the first blowing pipe 25, and a second branch pipe 24 is connected between the other end and the second blowing pipe 26. The first discharge pipe 4 corresponds to the first blowing pipe 25, and the second discharge pipe 7 corresponds to the lower sieve plate 63.

[0038] During the screening process of calcium carbonate powder, air can be blown through the fan 21, so that the connecting valve 22 can be used to divert the air into the first branch pipe 23 and the second branch pipe 24, and then discharged into the first blowing pipe 25 and the second blowing pipe 26 respectively. At this time, the first blowing pipe 25 blows the calcium carbonate fine powder floating above the upper sieve plate 64 into the first discharge pipe 4, and the second blowing pipe 26 blows the calcium carbonate fine powder floating above the lower sieve plate 63 into the second discharge pipe 7, and the calcium carbonate fine powder in the first discharge pipe 4 falls into the second discharge pipe 7, and falls into the collecting box 9 together with the calcium carbonate fine powder in the second discharge pipe 7, thereby realizing the screening of the calcium carbonate fine powder and facilitating the recycling of the calcium carbonate fine powder.

[0039] Furthermore, if Figure 1 , Figure 5 and Figure 8 As shown, a protection box is also installed on one side of the screening box 1, and the protection box cover is arranged outside the second motor 61 and the transmission belt.

[0040] During the operation of the second motor 61 and the transmission belt, the protection box can provide protection for them, thereby increasing the safety of the screening device.

[0041] In addition, in one embodiment, if Figure 3 and Figure 4 As shown, plug-in strips are installed on both sides of the bottom of the collection box 9, and plug-in grooves corresponding to the plug-in strips are opened on both sides of the inner wall of the groove cavity.

[0042] When the collecting box 9 is to be disassembled, the collecting box 9 can be pulled so that the collecting box 9 slides in the groove cavity on the lifting frame 57, and drives the plug-in strip to slide out of the plug-in groove, so as to realize the sliding disassembly of the collecting box 9 from the lifting frame 57, and then pour out the fine calcium carbonate powder collected in the collecting box 9 to realize the recycling of the fine calcium carbonate powder and complete the cleaning of the collecting box 9, and then insert the collecting box 9 into the groove cavity, and insert the plug-in strip into the plug-in groove to quickly position the collecting box 9 and the lifting frame 57, and then insert the baffle 58 on the lifting frame 57 to limit the collecting box 9 and complete the installation of the collecting box 9, thereby realizing the rapid disassembly and assembly of the collecting box 9, and making it more labor-saving to disassemble the collecting box 9 filled with fine calcium carbonate powder, and convenient for cleaning the collecting box 9.

[0043] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
