Detailed Description of the Invention

[0034] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Embodiment 1

[0035] An energy-saving calcium carbonate processing equipment, as Figures 1 - 12 shown, includes a housing 1 and a cylinder 2; the cylinder 2 is bolted inside the housing 1; several first through holes 1a are provided at the lower part of the housing 1, and a filter screen is provided on the first through holes 1a; the cylinder 2 is provided with an opening at the lower part; the cylinder 2 is provided with several feeding ports 2a;

[0036] It also includes a screw conveyor 3, a motor 4, a fan 5, a polygonal ball 201 and a scraper 204; an inner bottom of the housing 1 and an inner top surface of the cylinder 2 are jointly rotatably connected with a screw conveyor 3; the blades of the screw conveyor 3 are arranged in a mesh structure; the cylinder 2 is provided with a motor 4, and an output shaft of the motor 4 is fixedly connected to a rotating shaft of the screw conveyor 3; an upper part of the rotating shaft of the screw conveyor 3 is fixedly connected with a fan 5, and the fan 5 is located above the blades of the screw conveyor 3; a plurality of polygonal balls 201 are placed on the filter screen of the first through hole 1a; the cylinder 2 is provided with a plurality of discharge ports 2b distributed in an annular array, and the polygonal balls 201 are centrifugally thrown out from the discharge ports 2b, so as to fall downward between the housing 1 and the cylinder 2 and return to the filter screen of the first through hole 1a; a scraper 204 is arranged at a lower part of the blades of the screw conveyor 3.

[0037] The drying work of the calcium carbonate powder of the present invention is specifically as follows:

[0038] A calcium carbonate powder collection device is externally arranged below the first through hole 1a; the aperture of the filter screen on the first through hole 1a is smaller than the aperture of the mesh blades of the screw conveyor 3;

[0039] During the storage and transportation of the calcium carbonate powder, some of the calcium carbonate powder will be affected by moisture, and the moisture-affected calcium carbonate powder will agglomerate or cake. Therefore, it is necessary to dry the moisture-affected powder therein;

[0040] First, calcium carbonate powder is fed into the cylinder 2 from the feed inlet 2a. Among them, the dry and loose calcium carbonate powder, under the action of its own gravity, will sequentially pass through the mesh blades of the screw conveyor 3 and the filter screen on the first through hole 1a, and is collected by the calcium carbonate powder collection device below it.

[0041] Among them, the agglomerated or caked calcium carbonate powder, due to its large volume, cannot pass through the mesh blades of the screw conveyor 3 and the filter screen on the first through hole 1a, and stays on the mesh blades of the screw conveyor 3 or the filter screen of the first through hole 1a; at the same time, the output shaft of the motor 4 is controlled to drive the screw conveyor 3 to rotate, and the agglomerated or caked calcium carbonate powder located on the mesh blades of the screw conveyor 3 and the filter screen of the first through hole 1a is conveyed upward from bottom to top by the screw conveyor 3; moreover, when the screw conveyor 3 rotates, it will drive the fan 5 to rotate, and hot air flow is blown from top to bottom to dry the calcium carbonate powder in the cylinder 2;

[0042] With the transportation of the auger 3, the agglomerated or caked calcium carbonate powder will always be on the mesh blades at the top of the auger 3, closest to the fan 5. In this way, the agglomerated or caked calcium carbonate powder can be dried specifically. After the moisture contained in the agglomerated or caked calcium carbonate powder is dried, it will change from a wet agglomerated state to a dry and loose powdery state, and thus smoothly fall downward through the mesh blades of the auger 3 and the filter screen on the first through-hole 1a, and be collected by the calcium carbonate powder collection device below it. In this way, the drying operation of the calcium carbonate powder is completed, enabling the damp powder to be dried specifically and reducing the influence of the non-damp calcium carbonate powder on the drying operation, thereby improving the drying efficiency and drying effect of calcium carbonate.

[0043] Since the agglomerated or caked calcium carbonate powder contains moisture, the damp calcium carbonate powder will adhere to the mesh blades of the auger 3 and the filter screen of the first through-hole 1a. Moreover, the damp calcium carbonate powder has adhesiveness to the dry calcium carbonate powder, causing the mesh holes of the blades of the auger 3 and the filter screen holes of the first through-hole 1a to be blocked.

[0044] Therefore, when the blades of the auger 3 rotate, the scraping piece 204 on the blades of the auger 3 will scoop up the polygonal ball 201 and transport it upward along the blades of the auger 3 from bottom to top. During this process, the polygonal ball 201 will extrude the agglomerated or caked calcium carbonate powder on the blades of the auger 3, grinding the agglomerated or caked calcium carbonate powder; and during this process, the concave part 201a of the polygonal ball 201 will rub against and contact the agglomerated or caked calcium carbonate powder on the blades of the auger 3, causing the agglomerated or caked calcium carbonate powder to fall into the concave part 201a, and thus be carried by the polygonal ball 201 to the topmost blade of the auger 3. In this way, the drying efficiency and drying effect of the calcium carbonate powder are further improved.

[0045] Subsequently, when the blades of the auger 3 rotate, the polygonal ball 201 is centrifugally thrown out from the discharge port 2b under the action of inertia, and thus falls downward between the housing 1 and the cylinder 2 and returns to the filter screen of the first through-hole 1a to repeat the above operation. Example 2

[0046] Based on Example 1, as Figures 2 - 9As shown, a powder processing unit is also included, and the powder processing unit includes a rectangular frame 101, an extrusion plate 102, a mounting box 103 and an extrusion roller 104; the barrel 2 is bolted with the rectangular frame 101; the four sides of the rectangular frame 101 correspond to the discharge ports 2b one by one; each side of the rectangular frame 101 is provided with an extrusion plate 102; the rectangular frame 101 is provided with four mounting boxes 103 distributed in a rectangular shape, and the four mounting boxes 103 are distributed at the four corners of the rectangular frame 101; at least three extrusion rollers 104 distributed in a vertical array are rotatably connected between each two adjacent mounting boxes 103, and the extrusion rollers 104 are in contact with the extrusion plates 102 on the corresponding sides.

[0047] The powder processing unit also includes a connecting block 111 and an inclined plate 112; the shell 1 is configured as a rectangular structure; each inner side surface of the shell 1 is fixedly connected to a connecting block 111; each connecting block 111 is hingedly connected to an inclined plate 112, and each inclined plate 112 is located above the corresponding side extrusion roller 104.

[0048] The powder processing unit also includes an airbag 113; each inner side surface of the shell 1 is provided with an airbag 113, and each airbag 113 is respectively in contact with the inclined plate 112 on the corresponding side, and the airbag 113 is in contact with the extrusion roller 104 on the corresponding side, and a plurality of convex points are provided on the surface of the extrusion roller 104; each inclined plate 112 is respectively provided with a plurality of air outlet grooves 112a, and the air outlet grooves 112a are provided with air-permeable membranes to prevent powder from passing through the air outlet grooves 112a and entering the inclined plate 112; the airbag 113 is provided with a plurality of jet grooves 113a, and each jet groove 113a is respectively connected with the air outlet groove 112a on the corresponding side.

[0049] The powder processing unit further includes a spring rod 121 ; a plurality of spring rods 121 are disposed between each extrusion plate 102 and the rectangular frame 101 ; through the elastic force of the spring rods 121 , the extrusion plate 102 and the extrusion roller 104 can adapt to powders of different volumes.

[0050] The powder processing unit also includes a baffle 105 ; each extrusion plate 102 is provided with two baffles 105 distributed up and down, and the baffle 105 is in contact with the rectangular frame 101 , and the baffle 105 blocks the powder to prevent the powder from falling between the extrusion plate 102 and the rectangular frame 101 .

[0051] Each extrusion plate 102 is formed by three sections of plates hinged by torsion springs, and the torsion springs are located between the upper and lower adjacent extrusion rollers 104, so that the distances between the three extrusion rollers 104 and the corresponding extrusion plates 102 can be adjusted individually to accommodate different volumes of calcium carbonate powder.

[0052] The powder processing unit further includes a blower box 122 and a ventilation pipe 123; each side of the rectangular frame 101 is provided with an "eight"-shaped inclined opening 101a; a blower box 122 is provided at each of the four internal corners of each rectangular frame 101, and the air outlet of the blower box 122 faces the inclined opening 101a on the corresponding side; each blower box 122 is provided with a ventilation pipe 123, and the ventilation pipe 123 penetrates through the housing 1 and communicates with the outside.

[0053] The installation box 103 is set to be a hollow structure; an opening is provided at the lower part of the installation box 103, and the opening faces the filter screen of the first through hole 1a; a second through hole 103a is provided on each of the opposite surfaces of every two adjacent installation boxes 103, and every two opposite second through holes 103a are respectively located at both ends of the corresponding side extrusion roller 104.

[0054] A pump is externally connected to the ventilation pipe 123;

[0055] In the above process, when the calcium carbonate powder is conveyed by the auger 3, the agglomerated or caked calcium carbonate powder will always be on the mesh blades at the uppermost part of the auger 3. Therefore, the calcium carbonate powder entering the cylinder 2 from the feed port 2a will directly contact the agglomerated or caked calcium carbonate powder on the mesh blades at the uppermost part of the auger 3. When the agglomerated or caked calcium carbonate powder has not been dried and is blocked on the mesh blades at the uppermost part of the auger 3, the dry and loose calcium carbonate powder cannot smoothly pass through the mesh blades of the auger 3. As more powder is fed in, more powder is blocked on the mesh blades of the auger 3, resulting in a lower drying effect for the wet, caked, and agglomerated calcium carbonate powder in the lower layer, causing more serious blockage and seriously affecting the drying work of the calcium carbonate powder;

[0056] Therefore, when the mesh blades of the auger 3 rotate, a centrifugal force will be generated on the agglomerated or caked calcium carbonate powder thereon, causing it to be thrown out circumferentially and thus being thrown out through the discharge port 2b into the space between the housing 1 and the cylinder 2, and due to the influence of gravity, it will fall downward between the extrusion roller 104 and the extrusion plate 102;

[0057] At the same time, taking the left extrusion roller 104 as an example, control the three extrusion rollers 104 to rotate clockwise from the front view, and while rolling and dispersing the agglomerated or caked calcium carbonate powder through the extrusion roller 104 and the extrusion plate 102, convey it downward;

[0058] It should be noted that the calcium carbonate powder between the uppermost extrusion roller 104 and the extrusion plate 102 has the largest volume because it has just been thrown out from the discharge port 2b; the calcium carbonate powder between the lowermost extrusion roller 104 and the extrusion plate 102 has a smaller volume after being extruded by the upper two extrusion rollers 104. Therefore, when calcium carbonate powder passes through both the uppermost extrusion roller 104 and the lowermost extrusion roller 104 simultaneously, at this time, the distances between the three extrusion rollers 104 and the extrusion plate 102 are equal, and the calcium carbonate powder with a reduced volume passing through the lowermost extrusion roller 104 cannot be subjected to the extrusion force of the extrusion plate 102, which affects the rolling and dispersion effects of the calcium carbonate powder.

[0059] Therefore, the extrusion plate 102 is divided into three sections, and each two sections of the extrusion plate 102 are hinged to each other, which can realize the individual adjustment of the distances between the three extrusion rollers 104 and the corresponding extrusion plate 102 to adapt to calcium carbonate powder of different volumes.

[0060] Meanwhile, control the pump connected to the air vent pipe 123 to send hot air into the air blower box 122 through the air vent pipe 123, and then blow it out from the air outlet of the air blower box 122 through the inclined opening 101a towards the calcium carbonate powder between the extrusion roller 104 and the extrusion plate 102. In this way, while the hot air blown out through the inclined opening 101a dries the calcium carbonate powder between the extrusion roller 104 and the extrusion plate 102, because the inclined opening 101a is in an "eight" shape, the inclined opening 101a will blow the calcium carbonate powder between the extrusion roller 104 and the extrusion plate 102 from the inside to the outside, dispersing the crushed calcium carbonate powder to achieve a better drying effect.

[0061] It should be noted that the setting of the inclined plate 112 can prevent the calcium carbonate powder from falling between the inner side of the housing 1 and the extrusion roller 104; however, since the calcium carbonate powder in this part is in a wet state and has strong adhesiveness, it is difficult to fall downward after adhering to the inclined plate 112.

[0062] When the extrusion roller 104 rotates, the bumps provided on its surface will squeeze the airbag 113, thereby causing a change in the gas volume of the airbag 113, resulting in the vibration of the airbag 113 and shaking the calcium carbonate powder on the inclined plate 112 downward.

[0063] Moreover, when the airbag 113 is squeezed, the gas in the airbag 113 will be ejected through the air jet groove 113a towards the air outlet groove 112a, and through the ejected air flow, a wind curtain is formed to block the calcium carbonate powder centrifugally thrown out from the discharge port 2b, thereby reducing the adhesion amount of the calcium carbonate powder on the inclined plate 112.

[0064] After the polygonal ball 201 is centrifugally thrown out from the uppermost blade of the auger 3, it enters between the extrusion roller 104 and the extrusion plate 102 through the discharge port 2b. Since the volume of the polygonal ball 201 is larger than the maximum distance between the extrusion roller 104 and the extrusion plate 102, it cannot move downward between the extrusion roller 104 and the extrusion plate 102, and is constantly flipped by the extrusion roller 104 and the extrusion plate 102, thereby scraping out the calcium carbonate powder in the recessed portion 201a of the polygonal ball 201; in this way, the agglomerated or caked calcium carbonate powder can be brought between the extrusion roller 104 and the extrusion plate 102 by the polygonal ball 201, and crushed and dispersed by the extrusion roller 104 and the extrusion plate 102 to be further dried.

[0065] Subsequently, the polygonal ball 201 will be moved toward both ends of the squeezing roller 104 by the airflow blown out by the oblique opening 101a, and enter the installation box 103 through the second through hole 103a, and then return to the filter screen of the first through hole 1a to move the next batch of calcium carbonate powder. Example 3

[0066] On the basis of Example 2, Figures 10 - 11 As shown, it also includes a spring telescopic rod 202 and a rotating rod 203; at least four spirally distributed spring telescopic rods 202 are arranged on the inner side of the cylinder 2, and the telescopic parts of the spring telescopic rods 202 are in contact with the blades of the auger 3; each telescopic part of the spring telescopic rod 202 is respectively provided with a rotating rod 203.

[0067] When the polygonal ball 201 moves to the uppermost blade of the auger 3, the polygonal ball 201 will contact the rotating rod 203, thereby being moved by the rotating rod 203, causing the polygonal ball 201 to roll and contact the calcium carbonate powder on the uppermost blade of the auger 3, thereby improving the extrusion and grinding ability of the polygonal ball 201 relative to the agglomerated or lumped calcium carbonate powder. At the same time, the recessed portion 201a allows more calcium carbonate powder to adhere to the recessed portion 201a, thereby improving the calcium carbonate powder carrying capacity of the polygonal ball 201.

Any equivalent substitutions made within the principles of the present invention should be included in the protection scope of the present invention.
