Description

Technical Field

[0001] The utility model relates to the technical field of powder processing, in particular to a vibrating screen for calcium powder processing. Background Art

[0002] Calcium powder, commonly known as limestone or stone powder, is mainly composed of calcium carbonate, which is weakly alkaline, insoluble in water, and soluble in acid. Calcium powder can be divided into: heavy calcium powder, light calcium powder, active calcium powder, flue gas desulfurization calcium powder, ultrafine calcium carbonate, etc.

[0003] Nowadays, calcium powder is often processed through a vibrating screen, which works by using the reciprocating vibration generated by the excitation of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce a plane gyratory vibration, while the lower rotating weight causes the screen surface to produce a conical gyratory vibration. The combined effect of the two causes the screen surface to produce a compound gyratory vibration.

[0004] Chinese patent document CN209452288U discloses a vibrating screen for powder processing, wherein a first screen and a second screen are arranged horizontally in a screen drum in sequence, the screen hole diameter of the first screen is larger than the screen hole diameter of the second screen, a first driving mechanism drives the first screen to rotate around the axial direction of the screen drum, and a second driving mechanism drives the second screen to rotate around the axial direction of the screen drum; a plurality of grinding structures are arranged at the bottom of the first screen, and the plurality of grinding structures are distributed circumferentially around the axial direction of the screen drum. The vibrating screen for powder processing with the above-mentioned optimized design is provided with grinding structures distributed along the circumference at the bottom of the first screen, and when the first screen and the second screen rotate to screen the material, the grinding structure at the bottom of the first screen performs secondary grinding on the powder between the second screen and the first screen, on the one hand, the powder is secondary crushed to increase the amount of material passing through the second screen, and on the other hand, the screening speed of the second screen is increased, thereby improving the screening efficiency.

[0005] During the implementation process, the above patent document can perform secondary crushing of the powder, increase the amount of material passing through the second screen, and improve the screening efficiency. However, it is inconvenient to disassemble and replace the screen, resulting in a large number of large particles of powder being blocked by the screen mesh after long-term use, causing the vibration screening efficiency of the screen for calcium powder to be reduced.

DETAILED DESCRIPTION

[0022] 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 described below in conjunction with specific implementation methods.

[0023] like Figure 1 As shown, a vibrating screen for calcium powder processing includes a vibrating screen body 1, a connecting mechanism 2 is fixedly connected to the upper part of the vibrating screen body 1, and a screening mechanism 3 can be installed. The connecting mechanism 2 is slidably connected to the screening mechanism 3, and the calcium powder can be vibrated and screened. The screening mechanism 3 is externally threadedly connected to a feeding mechanism 4, and the input calcium powder can be transported. The feeding mechanism 4 is fixedly connected to a driving mechanism 5 on the upper part, and the unloading mechanism 6 can be driven to rotate. The driving mechanism 5 is fixedly connected to the unloading mechanism 6 on the lower part, and the calcium powder accumulated in the inner cavity of the conical funnel 42 can be stirred so that it can be unloaded smoothly downward.

[0024] In order to achieve the purpose of installing the screening mechanism 3, refer to Figure 3The connecting mechanism 2 includes an externally threaded connecting shell 21, and a plurality of arc-shaped limiting plates 22 are fixedly connected to the bottom wall of the inner cavity of the externally threaded connecting shell 21 in an annular array. The arc-shaped limiting plates 22 can cooperate with the screening frame 31 through the gaps between each other, thereby achieving the function of limiting the screening frame 31 installed in the inner cavity of the externally threaded connecting shell 21.

[0025] In order to achieve the purpose of vibrating and screening calcium powder, refer to Figure 3 The screening mechanism 3 includes a screening frame 31, a screen 32 is fixedly connected to the middle of the inner cavity of the screening frame 31, and a plurality of T-shaped fixing blocks 33 are fixedly connected to the upper end of the outer surface of the screening frame 31 in a circular array, which can facilitate the holding and installation of the screening frame 31, and the screening frame 31 is sleeved between a plurality of arc-shaped limiting plates 22.

[0026] When the screening frame 31 needs to be installed, the screening frame 31 can be aligned with the gaps between the matching arc-shaped limit plates 22 by holding two of the T-shaped fixing blocks 33. At this time, when the internal threaded sleeve 41 and the conical funnel 42 are rotated and tightened on the outer surface of the external threaded connection shell 21, the lower end of the outer surface of the conical funnel 42 will press down and fix the T-shaped fixing blocks 33, so that the screening frame 31 installed in the inner cavity of the external threaded connection shell 21 will not loosen during the operation of the vibrating screen body 1.

[0027] In order to achieve the purpose of conveying the calcium powder, refer to Figure 4 The feeding mechanism 4 includes an internal threaded casing 41, and a conical funnel 42 is fixedly connected to the upper end of the outer surface of the internal threaded casing 41, which can facilitate the delivery and transportation of calcium powder. The conical shape of the conical funnel 42 avoids the phenomenon of calcium powder scattering to the outside during the delivery of calcium powder, and the inner diameter of the bottom of the conical funnel 42 is the same as the inner diameter of the screening frame 31, so the screening frame 31 installed in the inner cavity of the external threaded connection shell 21 can be fixed. The inner surface of the internal threaded casing 41 is threadedly connected to the outer surface of the external threaded connection shell 21.

[0028] In order to achieve the purpose of driving the unloading mechanism 6 to rotate, refer to Figure 4 The driving mechanism 5 includes a support frame 51, and a motor 52 is fixedly connected to the middle of the upper end of the outer surface of the support frame 51, which can drive the connecting shaft 61 to rotate and then drive a number of unloading plates 62 to rotate. The lower end of the outer surface of the support frame 51 is fixedly connected to the upper end of the outer surface of the conical funnel 42.

[0029] In order to achieve the purpose of stirring the calcium powder accumulated in the inner cavity of the conical funnel 42 so that it can be discharged smoothly downward, refer to Figure 4The unloading mechanism 6 includes a connecting shaft 61, and a plurality of groups of unloading plates 62 are fixedly connected to the lower end of the outer surface of the connecting shaft 61 at intervals, and the sizes of the plurality of groups of unloading plates 62 decrease step by step from top to bottom. The upper end of the connecting shaft 61 is fixedly connected to the output end of the piston rod of the motor 52.

[0030] When the calcium powder put into the inner cavity of the connecting shaft 61 accumulates, the motor 52 is started so that the piston rod of the motor 52 drives the connecting shaft 61 to rotate, thereby causing the plurality of discharge plates 62 to rotate to stir the powder accumulated in the inner cavity of the conical funnel 42 so that it falls smoothly into the inner cavity of the internal threaded casing 41.

[0031] It should be noted that the specific installation method of the motor 52, the circuit connection method and the control method in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0032] The working principle of the utility model is as follows: when the screening frame 31 needs to be disassembled for cleaning or replacement, firstly, the internal threaded casing 41 is rotated counterclockwise to remove the internal threaded casing 41 and the conical funnel 42, and then the screening frame 31 is slid out of the inner cavity of the external threaded connection shell 21 by holding the T-shaped fixing block 33, and when calcium powder is added to the inner cavity of the conical funnel 42 to generate accumulation, the power supply of the motor 52 can be turned on, so that the plurality of unloading plates 62 rotate to stir the powder accumulated in the inner cavity of the conical funnel 42 to make it fall into the inner cavity of the internal threaded casing 41.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
