Description

Technical Field

[0001] The utility model belongs to the field of raw material loading and unloading, and relates to a central disc feeder. Background Art

[0002] Center disc feeder is a common raw material feeding equipment, widely used in metallurgy, coal, chemical industry, building materials, grain and other fields. Using center disc feeder for feeding can make the material evenly enter the next conveying equipment from the silo. It has the advantages of light size, simple maintenance and stable operation.

[0003] The scraper and discharge port of the common center disc feeder are on the side of the disc. The centrifugal force generated by the rotation of the disc is used to push the material outward to the discharge port and transport it to the lower equipment under the guidance of the scraper. This operation method also has many shortcomings. First, the discharge port is often narrow, which is easy to cause blockage when the material volume is large and the material fluidity is poor. Second, a large amount of material pressure will gather at the scraper, which is easy to cause damage and failure of the scraper and disc. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a central disc feeder.

[0005] In order to achieve the above object, the utility model provides the following technical solutions:

[0006] A central disc feeder is provided with a guide body, a scraper and a disc body along the material flow direction. The guide body and the scraper are fixedly arranged, the disc body is rotatably arranged around its axis, and a material discharge through hole is arranged at the center of the disc body; the material falls onto the disc body along the guide body, the disc body rotates, the scraper disperses the material and the material falls through the material discharge through hole.

[0007] Optionally, the guide body is conical.

[0008] Optionally, a connection shell is arranged around the outside of the flow guide, the flow guide is arranged on the connection shell by at least two support arms, and the scraper is arranged on a side of the support arm facing the disc body and is fixedly connected to the connection shell.

[0009] Optionally, a supporting disk is arranged on a side of the disk body away from the flow guide body, and the disk body is driven to rotate by a driving device arranged on a side of the supporting disk.

[0010] Optionally, the driving device includes a driving motor, a pinion is arranged on the output shaft of the driving motor, and a driven gear meshing with the pinion is arranged on the disc body.

[0011] Optionally, a material discharge hopper matching the position of the material discharge through hole is provided on the support plate.

[0012] Optionally, a central axis is provided on the flow guide body, and the scraper is arranged on the central axis via a mounting bearing.

[0013] Optionally, the scraper is arranged on the connecting shell by a connecting plate.

[0014] Optionally, a wear-resistant lining is provided on the surface of the disc body facing the scraper.

[0015] Optionally, a disc shield is arranged around the outer side of the disc body.

[0016] Optionally, at least two legs are arranged below the support plate.

[0017] The beneficial effects of the utility model are:

[0018] The structural design of the center disc feeder given in this proposal changes the discharge port of the existing center disc feeder from the side of the disc to the center of the disc. The material flow is no longer guided by a scraper, but a guide body is set on the top. The material in the silo falls to the periphery of the disc body, and the scraper arranged around the middle scrapes the material to the discharge hole in the center of the disc body and outputs it to the next level of equipment. This design no longer uses centrifugal force to push the material, and the material does not have to pass through the narrow volute outlet. The material is driven to rotate during the rotation of the disc body and is directly squeezed into the discharge hole by the scraper, which effectively avoids the situation where the disc body is blocked due to poor material fluidity. During the unloading process, the bulk material is in a flowing state, avoiding the accumulation of materials for a long time. On the other hand, the scraper is set in multiple groups and fixed in multiple places. The force on the single scraper is smaller and more uniform, which can increase the service life of the scraper and reduce the maintenance workload.

[0030] See also Figure 1 to Figure 5, which is a central disc feeder, comprising a connecting shell 1, a scraper 3, a disc body 5, a supporting disc 8 and a driving device 9, wherein a flow guide 2 is arranged in the middle of the connecting shell 1; the scraper 3 is located below the flow guide 2, with its bottom close to the surface of the disc body 5, and is arranged in a circle around the middle axis of the flow guide 2; the disc body 5 is located below the connecting shell 1, and a material discharge through hole 15 is provided in the middle of the disc body 5; the supporting disc 8 is installed below the disc body 5, and a material discharge hopper 13 is provided in the middle of the supporting disc 8.

[0031] The connecting shell 1 and the middle flow guide 2 are an integral weldment, and the flow guide is welded to the shell of the connecting shell 1 through the support arm 4. A flange is provided on the upper part of the connecting shell 1 for connecting with the material bin discharge port.

[0032] like Figure 5 As shown, the scraper 3 has two pieces, one end of which is fixed to the middle shaft of the guide body 2 by installing a bearing 17 and is arranged spirally around the axis, and the other end is connected to the connecting shell 1 by a pin or bolt through a connecting plate 14. A wear-resistant lining plate can be installed on the inner side of the arc of the scraper 5, and a wear-resistant lining plate 6 is also installed on the upper surface of the disc body 5. A disc guard 7 is provided on the outer side of the disc body 5 to prevent material from scattering.

[0033] like Figure 4 As shown, a pinion 11 is installed on the output shaft 16 of the driving device 9, and the output shaft 16 is installed on the side of the supporting disk 8. The bottom flange of the disk body 5 is connected to the driven gear 12 by bolts. The pinion 11 is meshed with the driven gear 12 to drive the driven gear 12 and the disk body 5 to rotate.

[0034] The disc body 5 and the driven gear 12 are arranged in the support disc 8, and the driven gear 12 is fixed axially by a circular groove in the support disc 8. A support leg 10 for supporting the whole device is arranged below the support disc 8, and at least two support legs 10 are arranged, and four support legs 10 are arranged in this embodiment.

[0035] In summary, when the disc feeding equipment is working, the driving device 9 drives the pinion 11 to rotate, and the gear transmission drives the disc body 5 to rotate. When the material in the silo is feeding, it falls into the connecting shell 1, and the material flow is guided by the guide body 2, and falls to the periphery of the disc body 5. Driven by the rotation of the disc body 5, it contacts and impacts the scraper 3, and is pushed into the material drop hole 15 in the center of the disc body 5 under the pressure of the scraper 3. The lower part of the material drop hole 15 is connected to the lower hopper 13, and the material is transported to the lower equipment through the lower hopper 13. During the unloading process, the bulk materials are in a flowing state to avoid long-term accumulation of materials. The disc scraper 3 is set in multiple groups and fixed in multiple places, which improves the stability of the scraper 3 and is also convenient for replacing the scraper 3 when damaged, without replacing the entire equipment.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
