Technical Field

[0001] The utility model relates to the technical field of calcium powder processing, and particularly relates to a multi-stage screening device for calcium powder. Background Art

[0002] Calcium powder, commonly known as limestone and stone powder, mainly consists of calcium carbonate, is weakly alkaline, insoluble in water, and soluble in acid.

[0003] Before the calcium powder is processed, the ground calcium powder needs to be subjected to multi-stage screening to distinguish calcium powder with different particle sizes, so as to meet the specific requirements of different industries and applications. In the prior art, screening is generally carried out through multiple screening plates, so that the calcium powder can be subjected to multi-stage screening.

[0004] However, the screening plates are all flat structures, so the processing capacity for large or irregularly shaped materials is limited, and it is easy for large waste materials to be not discharged in time and block the discharge holes. Therefore, the utility model provides a multi-stage screening device for calcium powder, so that materials of various shapes can be screened, and large waste materials can be discharged in time to avoid blocking the discharge holes.

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will, with reference to the accompanying drawings of the embodiments of the present utility model Figures 1-5 , clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model fall within the scope of protection of the present utility model.

[0026] As Figures 1-5 shown: A multi-stage screening device for calcium powder includes a fixed cylinder 101. The fixed cylinder 101 is provided so that the components thereon can be supported, and it can also prevent dust from being generated during the screening of calcium powder, thereby avoiding harm to the physical health of the staff. An inlet 105 is opened at the axis of the vertical surface on one side of the fixed cylinder 101. The inlet 105 is provided so that the calcium powder to be screened can be added into a plurality of screening cylinders 104 through the inlet 105 for screening. The inlet 105 can be opened by a cutting machine. A first rotating disk 102 is rotatably connected to the vertical inner wall on the side of the fixed cylinder 101 close to the inlet 105. The first rotating disk 102 is provided so that one side of a plurality of screening cylinders 104 can be supported. The first rotating disk 102 is rotatably connected to the vertical inner wall on one side of the fixed cylinder 101 through a thrust bearing, so that it will not get stuck when rotating. A plurality of screening cylinders 104 are sequentially connected to the surface on the side of the first rotating disk 102 away from the inlet 105. The plurality of screening cylinders 104 are provided so that the calcium powder added thereto will be subjected to multi-stage screening through the plurality of screening cylinders 104, thereby meeting the requirements of different industries. The first rotating disk 102 is welded to one end of the screening cylinder 104 closest to it, so that its connection structure is more stable.

[0027] Multiple screening cylinders 104 are all welded end to end in sequence, so that the multiple screening cylinders 104 can be closely connected, thereby increasing the screening effect. A material guiding platform 107 is arranged on the inner side wall of the multiple screening cylinders 104. By setting the material guiding platform 107, the calcium powder can be guided, so that the multiple screening cylinders 104 can continuously guide the calcium powder without tilting, avoiding the calcium powder to be screened from stopping at one place and rotating without being able to complete multi-stage screening. The material guiding platform 107 is welded on the inner side wall of the multiple screening cylinders 104, making its connection structure more stable. The cross-section of the material guiding platform 107 is set as a trapezoidal structure, which can improve the material guiding effect. And the material guiding platform 107 is connected to the inner side wall of the multiple screening cylinders 104 in a spiral structure, which can not only improve the material guiding effect but also not affect the screening effect. A plurality of screening holes are provided on the multiple screening cylinders 104. By setting the plurality of screening holes, the calcium powder can be screened. The plurality of screening holes and the corresponding screening cylinders 104 can be integrally formed by die casting during production, making their connection structure more stable.

[0028] One end of the screening cylinder 104 far from the first rotating disk 102 is provided with a second rotating disk 103. By setting the second rotating disk 103, the other ends of the multiple screening cylinders 104 can be driven by a driving mechanism. The second rotating disk 103 is welded to one end of the last screening cylinder 104, making its connection structure more stable. The aperture of the screening holes provided on the multiple screening cylinders 104 increases sequentially in the direction from the first rotating disk 102 to the second rotating disk 103, so that the calcium powder in the multiple screening cylinders 104 can be subjected to multi-stage screening. Therefore, the fine calcium powder falls first, and then the particle size increases sequentially, while the unwanted particle sizes will be discharged to the end and discharged by the discharge pipe 108, so that materials of various shapes can be screened, and large waste materials can be discharged in time to avoid blocking the discharge holes. First driving grooves are provided on the outer side walls of the first rotating disk 102 and the second rotating disk 103. By setting the first driving grooves, the driving wheel 202 can be limited in cooperation with the second driving grooves, and the rotation of the driving wheel 202 can drive the first rotating disk 102 and the second rotating disk 103 to rotate. Therefore, the multiple screening cylinders 104 rotate accordingly to screen the calcium powder.

[0029] The first driving groove can be integrally formed by die casting when manufacturing the first rotating disk 102 and the second rotating disk 103, so as to make its connection structure more stable. Limiting disks 201 are arranged on the inner side wall of the fixed cylinder 101 corresponding to the positions of the first rotating disk 102 and the second rotating disk 103. The limiting disks 201 are welded to the inner side wall of the fixed cylinder 101. Second driving grooves are opened in both limiting disks 201 corresponding to the positions of the two first driving grooves. The limiting disks 201 are provided to cooperate with the second driving grooves so that the driving wheels 202 can drive them. The second driving grooves can limit the driving wheels 202, and can also further support the first rotating disk 102 and the second rotating disk 103 through the driving wheels 202 to prevent them from falling off during driving. The second driving grooves and the limiting disks 201 can be integrally formed by die casting during manufacturing, so as to make their connection structure more stable. Multiple groups of driving mechanisms are arranged between the first driving grooves and the second driving grooves. By arranging multiple groups of driving mechanisms, multiple driving wheels 202 can rotate synchronously, and then the first rotating disk 102 and the second rotating disk 103 can be driven. Therefore, multiple screening cylinders 104 can be driven to rotate accordingly, so that the calcium powder inside can be multi-stage screened. An outlet 106 is opened on the fixed cylinder 101 facing the ground direction. The outlet 106 is provided so that the screened calcium powder can be discharged. The outlet 106 can be opened by a cutting machine.

[0030] Each group of driving mechanisms includes a driving wheel 202 arranged in each first driving groove and each second driving groove. By arranging the driving wheel 202, the driving wheel 202 rotates to drive the first rotating disk 102 and the second rotating disk 103 to rotate synchronously, and then drives multiple screening cylinders 104 to rotate accordingly. The driving wheel 202 is rotatably connected in the first driving groove and the second driving groove, so that the driving wheel 202 can be limited and can also support the first rotating disk 102 and the second rotating disk 103, thereby increasing their stability. A transmission rod 203 is arranged at the axis centers of the two driving wheels 202. By arranging the transmission rod 203, the transmission rod 203 rotates to drive the driving wheels 202 arranged thereon to rotate accordingly. The transmission rod 203 passes through the two driving wheels 202 and is fixedly connected to the driving wheels 202. Moreover, a rubber layer is wrapped on the outer side wall of the driving wheel 202. By arranging the rubber layer, the friction force can be increased to make the driving effect better. The transmission rod 203 passes through the fixed cylinder 101, so that the motor 204 can be connected to the transmission rod 203.

[0031] One end of each transmission rod 203 is provided with a motor 204. The output shaft of the motor 204 is connected to one end of the transmission rod 203 through a coupling, so that the output shaft of the motor 204 rotates, and then drives the transmission rod 203 to rotate accordingly. Multiple motors 204 need to be set to rotate synchronously and in the same direction. One side of the motor 204 is provided with an L-shaped support plate 205. The L-shaped support plate 205 is provided to support the motor 204, thereby preventing the output shaft of the motor 204 from rotating and self-rotating. The motor 204 is connected to one side surface of the L-shaped support plate 205 by bolts, making it convenient to disassemble and assemble the motor 204. One end of the L-shaped support plate 205 is connected to the outer side wall of the fixed cylinder 101, so that the L-shaped support plate 205 can be supported. One end of the L-shaped support plate 205 is connected to the outer side wall of the fixed cylinder 101 by bolts, making it convenient to disassemble and assemble. On the side surface of the second rotating disk 103 away from the screening cylinder 104, there is a discharge pipe 108. The discharge pipe 108 is provided so that the calcium powder that does not meet the size particle size after screening can be discharged through the discharge pipe 108, thereby preventing it from staying in the multiple screening cylinders 104 and causing the screening holes to be blocked. Therefore, the screening holes can be prevented from being blocked. The discharge pipe 108 can be connected to one side of the second rotating disk 103 by a flange, making it convenient to disassemble and assemble. And the discharge pipe 108 is set as a corrugated pipe structure, so that its orientation can be adjusted.

[0032] Below the discharge port 106, corresponding to the positions of the multiple screening cylinders 104, there are multiple storage boxes 304. The multiple storage boxes 304 are sequentially placed above the ground and corresponding to the positions of the multiple screening cylinders 104. The multiple storage boxes 304 are provided so that the calcium powder with different particle sizes can fall into the corresponding storage boxes 304 for storage after screening. Symmetrically arranged on the lower part of the outer side wall of the fixed cylinder 101 are support frames 301. The support frames 301 are provided so that the fixed cylinder 101 and its various components above can be supported. The fixed cylinder 101 is connected to the upper part of the support frame 301 by bolts, making it convenient to disassemble and assemble. Both lower parts of the two support frames 301 are provided with connecting plates 302. The connecting plates 302 are provided so that the support legs 303 can be fixed. The connecting plates 302 are welded to the lower parts of the support frames 301, making their connection structure more stable. Symmetrically arranged on the lower part of each connecting plate 302 are support legs 303. The support legs 303 are provided so that the various components above can be stably supported. The support legs 303 are welded to the lower parts of the connecting plates 302, making their connection structure more stable. On the side surface of the feed inlet 105 away from the screening cylinder 104, there is a guide plate 109. The guide plate 109 is provided so that the calcium powder can be added into the screening cylinder 104 closest to the feed inlet 105 through the guide plate 109. The guide plate 109 is inclined and fixedly connected to the outer side wall of the fixed cylinder 101 at the feed inlet 105, making its connection structure more stable.

[0033] Usage method of the present utility model:

[0034] When it is necessary to screen calcium powder, place the storage box 304 in the corresponding position, and then start multiple motors 204 so that the multiple motors 204 drive the transmission rod 203 to rotate. The rotation of the transmission rod 203 drives the driving wheel 202 to rotate accordingly. Subsequently, the multiple driving wheels 202 rotate in the first driving grooves in the first rotating disk 102 and the second rotating disk 103. Under the influence of friction, the first rotating disk 102 and the second rotating disk 103 drive the multiple screening cylinders 104 thereon to rotate accordingly. At this time, pour the calcium powder through the material guiding plate 109, so that the calcium powder will continuously move and be screened under the action of the material guiding table 107, enabling the calcium powder to be screened at multiple levels. The screened calcium powder will fall into different storage boxes 304 for collection according to its particle size, and those that do not meet the specifications will be discharged through the discharge pipe 108. After collection, it can be pulverized again to make it meet the specification size. Thus, the screening cylinder 104 is used to replace the screening plate, enabling materials of various shapes to be screened. Moreover, by setting the material guiding table 107 in cooperation with the discharge pipe 108, large waste materials can be discharged in a timely manner to avoid blocking the screening holes.

[0035] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0036] The above is the preferred implementation mode of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
