Description

Technical Field

[0001] The utility model belongs to the technical field of bulk material processing and relates to a disc feeder. Background Art

[0002] Disc feeder is a feeding device commonly used at the bottom of silo. It is widely used in metallurgy, coal, chemical industry, building materials, grain and other fields. Using 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 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 end equipment under the guidance of the scraper. This operation method also has many shortcomings. First, the position of the discharge port is often small, which is easy to cause blockage when the material volume is large and the material fluidity is poor. Second, the mixing effect is not good, and a large amount of material is squeezed out from one side, which is not conducive to material mixing. Utility Model Content

[0027] Specific embodiment 1,

[0028] like Figure 1-Figure 3As shown, a disc feeder comprises a disc 1, a driving device 3, and 6 pairs of scrapers 2 connected around the disc. The driving device 3 drives the disc and its scrapers to rotate around the center of the disc. A certain gap is formed between the disc 1 and the upper silo 5, and materials 4 are naturally accumulated on the surface of the disc. The disc feeder also comprises a shell 6, which is installed on the outside of the disc 1 and the scraper 2 to prevent dust from escaping. An integrally formed material storage platform is provided at the bottom of the shell. The material storage cavity formed between the material storage platform and the shell is an annular U-shaped groove 7 structure. The U-shaped groove 7 is located on the outside of the lower part of the disc to store the material 4 accumulated on the disc. The disc rotates to disturb the material falling into the material; a discharge port 8 is also provided at a designated position at the bottom of the U-shaped groove to facilitate material discharge; the scrapers 2 around the disc rotate around the center of the disc in the U-shaped groove, and push the material in the U-shaped groove 7 to the discharge port 8 at the bottom of the U-shaped groove 7; a partition plate 9 is provided on the disc shell at a position corresponding to the discharge port, and the partition plate 9 is used to block the material to prevent the material from falling directly from the disc into the discharge port 8; the disc shell is also provided with an adjustment baffle 10, and the adjustment baffle can adjust the height of the baffle from the disc surface to adjust the amount of material falling into the surrounding U-shaped grooves under the disturbance of the disc.

[0029] In this embodiment, the top of the disc shell and the upper silo form a seal to prevent dust from escaping.

[0030] In this embodiment, a wear-resistant lining is provided on the upper surface of the disc.

[0031] In this embodiment, the scraper is made of wear-resistant material.

[0032] In this embodiment, the specific working method is as follows: materials are stored in the silo 5, and the materials are accumulated on the upper surface of the disc 1. Due to the natural accumulation angle of the materials themselves, the materials can be accumulated on the upper surface of the disc when the disc is stationary, and the materials will not fall into the U-shaped grooves 7 around the disc. In addition, a partition is provided at the corresponding position of the disc shell to ensure that the materials will not fall directly from the disc into the discharge port 8. When the disc rotates, the materials fall into the U-shaped grooves 7 around the disc under the action of the disc disturbance and centrifugal force, and are pushed to the discharge port 8 by the scrapers 2 around the disc, and are output through the conveyor 11 below the discharge port.

[0033] Specific embodiment 2,

[0034] The difference between this embodiment and specific embodiment 1 is that a disc scraper 11 is provided on the upper surface of the disc of this embodiment. The scraper is fixed to the disc and rotates together with the disc to better push the material to the U-shaped groove around the disc, which is particularly suitable for materials with poor flow properties.

[0035] 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.
