Description

Technical Field

[0001] The utility model belongs to the technical field of bulk material storage and loading and unloading, and relates to a disc type mixing 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] At present, the common disc feeder has the scraper and discharge port 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 then convey it to the lower end equipment under the guidance of the scraper. This operation method has many disadvantages: the discharge port is often narrow, which is easy to cause blockage when the material volume is large and the material fluidity is poor; a large amount of material is squeezed out from one side, which is not conducive to material mixing, resulting in poor mixing effect. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a disc type mixing feeder, which can prevent material blockage and enhance the mixing effect of materials.

[0005] To achieve the above-mentioned purpose, the utility model provides a disc type mixing feeder, which includes a double-layer disc attached to the bottom outlet of the silo, the double-layer disc includes an upper disc and a lower disc coaxially or coaxially connected in the vertical direction, and the diameter of the upper disc is smaller than the diameter of the lower disc.

[0031] like Figure 1 to Figure 5 As shown, the utility model provides a disc type mixing feeder. The disc type mixing feeder comprises a double-layer disc 100 attached to the bottom outlet of a silo 500, the double-layer disc 100 comprises an upper disc 110 and a lower disc 120 coaxially connected in a vertical direction, the diameter of the upper disc 110 is smaller than the diameter of the lower disc 120, so that the material can fall from the edge of the upper disc 110 into the lower disc 120.

[0032] The double-layer disc 100 is arranged in the annular retaining wall 130, and the annular retaining wall 130 includes a bottom plate 132, a side plate 133 and an upper retaining plate 131. The lower disc 120 is rotatably arranged on the bottom plate 132, and the side plate 133 is vertically arranged along the edge of the bottom plate 132, and the upper retaining plate 131 is arranged on the upper edge of the side plate 133. The side wall of the side plate 133 is provided with a discharge port 121, and a discharge trough 300 is arranged at the edge of the lower disc 120 corresponding to the position of the discharge port 121, and the opening of the discharge trough 300 is lower than the edge of the lower disc 120.

[0033] The feeder also includes a driving device 400 for driving the double-layer disc 100 to rotate. The upper disc 110 and the lower disc 120 are connected by a connecting shaft 150. The driving device 400 is installed below the lower disc 120 and is connected to the connecting shaft 150. It is preferably a driving motor, which can drive the double-layer disc 100 to rotate by gear transmission or belt transmission.

[0034] The upper disc 110 includes a receiving disc 111 disposed at the center thereof and a plurality of diverter plates 112 disposed between the receiving disc 111 and the upper disc 110. The diverter plates 112 are evenly distributed on the outer edge of the receiving disc 111 and extend outward to the outer edge of the upper disc 110. The diverter plates 112 preferably extend along the radial direction of the receiving disc 111. The material falls from the silo 500 into the receiving disc 111. Under the centrifugal force during the rotation of the upper disc 110, the material moves from the center of the receiving disc 111 to the edge, and falls evenly into the lower disc 120 under the action of the diverter plates 112.

[0035] A plate-shaped scraper 200 is provided on the side plate 133 at a position corresponding to the discharge port 121, and the scraper 200 is vertically arranged between the upper disc 110 and the lower disc 120. The lower disc 120 rotates so that the materials converge at the scraper 200 and are then discharged into the discharge chute 300. Furthermore, there is a certain gap between the upper disc 110 and the outlet of the silo 500 to prevent excessive accumulation of materials on the receiving tray 111. In other embodiments, a cone 114 whose diameter gradually decreases upward in the vertical direction may also be provided on the receiving tray 111, and the cone 114 is inserted into the interior of the silo 500 to facilitate the discharge of materials from the silo 500. During the unloading process, the material passes through the diverter plate 112 of the upper disc 110 and falls evenly into the lower disc 120 , and then passes through the scraper 200 of the lower disc 120 and converges to the discharge chute 300 . The mixing effect of the material particles during the overflow and convergence is greatly enhanced, and the material blockage can also be prevented.

[0036] Furthermore, the outlet of the silo 500 is directly placed above the upper disc 110, and the diameter of the receiving plate 111 of the upper disc 110 matches the outlet size of the silo 500. The height of the side plate 133 is higher than the height of the upper disc 110, the inner diameter of the upper baffle 131 matches the diameter of the bottom of the silo 500, and the upper baffle 131 is connected to the outer wall of the silo 500 to form a closed structure. Furthermore, a plurality of scrapers 113 are fixedly arranged on the inner wall surface of the side plate 133 between the upper disc 110 and the upper baffle 131, one end of the scraper 113 is fixedly arranged on the side plate 133, and the other end extends toward the receiving plate 111 in the horizontal direction.

[0037] In order to prevent the material from accumulating in the connection gap between the lower disc 120 and the side plate 133 when falling from the upper disc 110, a guide wall 140 is further provided between the upper disc 110 and the lower disc 120. The upper edge of the guide wall 140 is fixed on the inner wall surface of the side plate 133 and is located below the scraper 113, and the lower edge thereof extends to the lower disc 120. Preferably, the guide wall 140 can be provided vertically with the lower disc 120 or be provided obliquely with respect to the lower disc 120 toward the center of the lower disc 120. Furthermore, the guide wall 140 is disconnected at the discharge port 121.

[0038] 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.
