The disc feeder includes a guide sleeve, a disc body and a disc shell. The material enters the guide sleeve and falls into the disc body in the disc shell. The disc body rotates so that the material can flow out from the discharge port connected to the side of the disc shell.

[0003] At present, the disc body is coaxially and rotatably arranged in the disc shell. There is an annular gap required for rotation between the circumferential wall of the disc body and the inner circumferential wall of the disc shell, and there is also a gap required for rotation between the end face of the disc body and the bottom surface of the disc shell. During the operation of the disc feeder, a small amount of material will leak to the bottom surface of the disc shell through the annular gap between the disc body and the disc shell. The continuous discharge of material in the guide sleeve and the material falling to the bottom surface of the disc shell are likely to block the space between the disc body and the outer disc shell outlet, causing the disc feeder to be blocked and shut down, affecting the normal production of the equipment. Utility Model Content

[0004] The present application aims to solve the technical problem that the normal production of a disc feeder is affected to a certain extent at least. To this end, the present application provides a disc feeder and a material conveying system.

[0005] The present application embodiment provides a disc feeder for receiving materials flowing out of a silo, comprising:

[0006] A material guide sleeve is connected to the material bin and is provided with a material discharge channel;

[0007] The disc shell is provided with a cylindrical groove, a coal deposit discharge port and a discharge port. The opening of the cylindrical groove is sleeved on the guide sleeve. The bottom of the cylindrical groove is connected to the coal deposit discharge port, and the discharge port is connected to one side of the cylindrical groove.

[0008] The disc body is rotatably arranged on the disc shell and located in the cylindrical groove. The disc body rotates around its own axis and the axis of the disc body extends along the axial direction of the cylindrical groove. There is a gap between the disc body and the bottom of the cylindrical groove, and the gap is connected to the discharge port.

[0009] In some embodiments, the material guiding sleeve is disposed at one end of the cylindrical groove, and the bottom of the cylindrical groove is connected to a rectangular coal discharge port.

[0010] In some embodiments, the coal accumulation discharge opening is opposite to one end of the disc body, and the length of the coal accumulation discharge opening is smaller than the radius of the disc body.

[0011] In some embodiments, at least one coal discharge port is located between the discharge port and the axis of the disc shell.

[0012] In some embodiments, the disc feeder further comprises:

[0013] The material guiding piece is connected with the outer shell of the disc and is provided with a material guiding through groove which is connected to the material discharge port of the accumulated coal.

[0014] In some embodiments, the discharge port is used to convey the material entering the disc feeder to the conveying belt, and the material guide channel is used to convey the material to the conveying belt.

[0015] In some embodiments, the opening of the material guiding channel faces the material outlet.

[0016] In some embodiments, the disc shell is provided with at least two coal accumulation discharge ports distributed along the circumference of the disc shell, and the disc feeder further comprises a cover rotatably connected to the disc shell and used for opening and closing one of the coal accumulation discharge ports.

[0017] The present application provides a material conveying system for conveying materials, comprising:

[0018] As in the above-mentioned disc feeder, the disc housing includes a connected housing body and a discharge barrel, a cylindrical groove is provided in the housing body, an inner peripheral wall of the discharge barrel is connected to one side of the cylindrical groove, and a discharge port is formed at one end of the discharge barrel, and the discharge port is used to discharge the material;

[0019] The conveyor belt is opposite to the discharge port to receive the material.

[0020] In some embodiments, the disc feeder also includes a material guide member connected to the disc housing, the material guide member extends above the conveying belt, the material guide member is provided with a material guide groove connected to the coal discharge port, and is used to transport materials to the conveying belt.

[0021] Advantageous effects provided by one or more embodiments of the present application:

[0022] In the disc feeder, the material is fed into the feed channel of the guide sleeve, which is connected to the disc shell. The feed channel is inserted into the opening of the cylindrical groove of the disc shell. The material enters the cylindrical groove from the feed channel and falls onto the disc body which is rotatably matched with the disc shell and located in the cylindrical groove. The axis of the disc body extends along the axis of the cylindrical groove and can rotate around its own axis. The material falls to one end of the disc body, and the disc body rotates relative to the disc shell to move the material to the discharge port of the disc shell connected to one side of the cylindrical groove to transport the material. The bottom of the cylindrical groove in the disc shell is connected to the coal discharge port. When the disc body rotates relative to the disc shell, the material entering from the discharge channel will be transferred by the disc body to the discharge port for normal transportation, and some material will also fall from the annular gap between the circumferential wall of the disc body and the inner circumferential wall of the cylindrical groove to the bottom of the cylindrical groove. This part of the material is located in the gap between the disc body and the bottom of the cylindrical groove. The accumulated coal in the gap can be discharged from the coal discharge port. When space is left in the gap and the gap is connected to the discharge port, it is not easy for material to accumulate at the gap and the discharge port, which reduces the occurrence of material accumulation in the cylindrical groove and clogging the discharge port, ensuring the normal operation of the disc feeder and solving the technical problems that affect the normal production of the disc feeder to a certain extent.

[0032] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Figure 1 A schematic diagram of the structure of a disc feeder in some or certain embodiments of the present application is shown. Figure 2 A bottom view of a disc housing in some or certain embodiments of the present application is shown, with reference to Figure 1 and Figure 2 The present application embodiment provides a disc feeder for receiving materials flowing out of a silo (not shown in the figure), comprising:

[0034] The material guiding sleeve 1 is communicated with the material bin and is provided with a material discharge channel 11 .

[0035] The disc shell 2 is provided with a cylindrical groove 21, a coal discharge port 22 and a discharge port 23. The opening of the cylindrical groove 21 is sleeved on the guide sleeve 1. The bottom of the cylindrical groove 21 is connected to the coal discharge port 22, and the discharge port 23 is connected to one side of the cylindrical groove 21.

[0036] The disc body 3 is rotatably disposed on the disc housing 2 and is located in the cylindrical groove 21. The disc body 3 rotates around its own axis and the axis of the disc body 3 extends along the axial direction of the cylindrical groove 21. There is a gap between the disc body 3 and the bottom of the cylindrical groove 21, and the gap is connected to the discharge port 23.

[0037] In the disc feeder, the material is fed into the feed channel 11 of the guide sleeve 1. The guide sleeve 1 is connected to the disc shell 2. The feed channel 11 is inserted into the opening of the cylindrical groove 21 of the disc shell 2. The material enters the cylindrical groove 21 from the feed channel 11 and falls onto the disc body 3 which is rotatably matched with the disc shell 2 and is located in the cylindrical groove 21. The axis of the disc body 3 extends along the axis of the cylindrical groove 21 and can rotate around its own axis. The material falls to one end of the disc body 3. The disc body 3 rotates relative to the disc shell 2, so that the material moves to the discharge port 23 of the disc shell 2 which is connected to one side of the cylindrical groove 21 to transport the material. The bottom of the cylindrical groove 21 in the disc shell 2 is connected to the coal discharge port 22. When the disc body 3 rotates relative to the disc shell 2, the material entering from the discharge channel 11 will be transferred to the discharge port 23 by the disc body 3 for normal transportation, and some materials will also fall to the bottom of the cylindrical groove 21 from the annular gap between the circumferential wall of the disc body 3 and the inner circumferential wall of the cylindrical groove 21. There is a gap between the disc body 3 and the bottom of the cylindrical groove 21. This part of the material is located in the gap between the disc body 3 and the cylindrical groove 21. The accumulated coal in the gap can be discharged from the coal discharge port 22. When space is left in the gap and the gap is connected to the discharge port 23, the gap and the discharge port 23 are not easily blocked, which reduces the occurrence of material accumulation in the cylindrical groove 21 and blocking the discharge port 23, ensuring the normal operation of the disc feeder and solving the technical problems that the normal production of the disc feeder is affected to a certain extent.

[0038] After the coal accumulation discharge port 22 is provided, the coal accumulation discharge port 22 can discharge excess materials during the normal operation of the disc feeder to transport materials, thereby ensuring the normal operation of the disc feeder and reducing possible blockage of the disc feeder.

[0039] It should be noted that, in the disc feeder, in order to ensure the stable rotation of the disc body 3 relative to the disc housing 2, there will be a certain annular gap (not shown in the figure) between the disc body 3 and the cavity wall of the cylindrical groove 21, so as to leave a rotation space between the cavity wall of the cylindrical groove 21 and the peripheral wall of the disc body 3. Due to its own design structure, the disc feeder will have more or less coal accumulation in the process of conveying materials, so the coal accumulation discharge port 22 is set, and even if the coal accumulation discharge port 22 is always in an open state, it will not affect the normal operation of the disc feeder.

[0040] For ease of understanding, the structure of the material guide sleeve 1 and the disc body 3 is described here. The material guide sleeve 1 is coaxially connected to the disc shell 2. There is a gap between one end of the material guide sleeve 1 and the end face of the disc body 3. The side of the material guide sleeve 1 may be provided with a material guide port connected to the material discharge channel 11 and extending to the end face of the disc body 3. The material guide port is connected to the material discharge port 23. The material can enter the material guide port from the material discharge channel 11 and then enter the material discharge port 23 from the material guide port. The disc body 3 is a circular plate with a groove. The groove and the short plate of the circular plate can push the material, so that when the disc body 3 rotates relative to the disc shell 2, the material can be driven and pushed, and the material can flow out from the material discharge port 23. The disc shell 2 can be similar to a cylinder, and one end is closed, so that the internal space of the disc shell 2 forms a cylindrical groove 21.

[0041] In some embodiments, along the axial direction of the disc body 3, the gap between the disc body 3 and one end of the cylindrical groove 21 connecting to the coal discharge port 22 can be controlled to be 3 to 6 mm. Within this range, the possibility of clogging of the disc feeder can be reduced and the discharge of accumulated materials is also convenient.

[0042] In some embodiments, the material guiding sleeve 1 is disposed at one end of the cylindrical groove 21 , and the bottom of the cylindrical groove 21 is connected to a rectangular coal discharge port 22 .

[0043] The guide sleeve 1 and the coal discharge port 22 are respectively located at the two axial ends of the disc shell 2, so that the guide sleeve 1 is located above the coal discharge port 22, which is convenient for discharge and discharge of the coal discharge port 22 at the bottom of the disc shell 2, and the vertical space utilization rate is also high. The rectangular coal discharge port 22 is convenient for preparation and discharge of coal.

[0044] In some embodiments, the coal accumulation discharge opening 22 is opposite to one end of the disc body 3 , and the length of the coal accumulation discharge opening 22 is smaller than the radius of the disc body 3 .

[0045] The coal discharge port 22 is opposite to one end of the disc body 3 to facilitate the discharge of the coal. The length of the coal discharge port 22 is smaller than the radius of the disc body 3, which can facilitate the discharge of the coal while ensuring the use strength of the disc shell 2.

[0046] In some embodiments, the shape of the coal deposit discharge port 22 may also be set to be circular, strip-shaped, or arc-shaped, which is not limited in the present application.

[0047] In some embodiments, at least one coal discharge port 22 is located between the discharge port 23 and the axis of the disc shell 2 .

[0048] The coal discharge port 22 is located between the discharge port 23 and the axis of the disc housing 2, and can discharge materials that are easily accumulated at the discharge port 23, effectively alleviate the situation where materials may accumulate at the discharge port 23, and improve the use stability of the disc feeder.

[0049] In some embodiments, the coal deposit discharge port 22 may also be arranged at other positions at one end of the disc housing 2. The deposited coal can also be discharged to reduce possible blockage of the disc feeder.

[0050] In some embodiments, the disc feeder further includes a material guide member 4 , which is connected to the disc housing 2 and is provided with a material guide groove 41 connected to the coal discharge port 22 .

[0051] The material guide member 4 is connected to the disc housing 2 and is provided with a material guide groove 41 communicating with the coal discharge port 22. The material guide groove 41 can guide the material to a proper destination, so as to facilitate the transportation of the material.

[0052] In some embodiments, the discharge port 23 is used to convey the material entering the disc feeder to the conveying belt 10, and the material guide channel 41 is used to convey the material to the conveying belt 10. Reducing material leakage can also improve the efficiency of material conveying.

[0053] In some embodiments, the opening of the material guiding slot 41 faces the discharge port 23. A corresponding receiving device is usually provided on one side of the discharge port 23. The opening of the material guiding slot 41 faces the discharge port 23, which can also guide the material to the corresponding receiving device and facilitate the cleaning and maintenance of the material guiding slot 41.

[0054] For ease of understanding, here is provided Figure 3 , Figure 3 A front view of a material guide member in some or certain embodiments of the present application is shown, with reference to Figure 3 The material guide member 4 can be a bent plate-like structure, and one end of which is connected to one end of the disc housing 2, and the material guide groove 41 is arranged on a plate surface of the material guide member 4. It is convenient for preparation and can also realize effective conveying of the accumulated material.

[0055] In some embodiments, the material guide member 4 may also be configured as a straight plate or a block according to requirements, etc. This application does not impose any limitation on this.

[0056] In some embodiments, the disc housing 2 is provided with at least two coal accumulation discharge ports 22 distributed along the circumference of the disc housing 2 , and the disc feeder further comprises a cover 5 detachably connected to the disc housing 2 and used for opening and closing one of the coal accumulation discharge ports 22 .

[0057] At least two coal accumulation discharge ports 22 are arranged on the disc housing 2, which has a better effect of preventing accumulation blockage. A cover 5 for opening and closing the coal accumulation discharge port 22 is arranged on one of the coal accumulation discharge ports 22. The number of coal accumulation discharge ports 22 opened during normal conveying of the disc feeder can be controlled according to the particle size of the material conveyed by the disc feeder, thereby improving the versatility of the disc feeder and ensuring the normal operation of the disc feeder.

[0058] In some embodiments, one side of the cover 5 is detachably connected to the disc housing 2, and the other side is detachably connected to the disc housing 2 by fasteners, etc. This facilitates the cover 5 to open and close the coal discharge port 22.

[0059] Based on the same inventive concept, the present application also provides a material conveying system for conveying materials. The structure of the material conveying system can also refer to Figure 1 , the material conveying system may include:

[0060] As in the previous disc feeder, the disc shell 2 includes a connected shell body 24 and a discharge barrel 25, a cylindrical groove 21 is provided in the shell body 24, an inner circumferential wall of the discharge barrel 25 is connected to one side of the cylindrical groove 21, and a side wall of the discharge barrel 25 and an opening at one end together form a discharge port 23, and the discharge port 23 is used for discharging materials.

[0061] The conveyor belt 10 is opposite to the discharge port 23 to receive the material.

[0062] The disc housing 2 includes the structure of the housing body 24 and the discharge barrel 25. When the axis of the disc housing 2 is arranged along the gravity direction, the downward end of the discharge barrel 25 can be configured as a discharge port 23 to facilitate the transportation of materials. Other structures and effects in the disc feeder can refer to the above and will not be repeated here. The conveying belt 10 is opposite to the discharge port 23, and the material can naturally fall to the conveying belt 10 for stable transportation.

[0063] Furthermore, when the disc feeder is operating normally, the accumulated coal in the disc feeder can be discharged from the designed coal discharge port 22 through the operation of the disc body 3 without stopping for maintenance. The discharge principle is that the accumulated coal is discharged through the dead weight of the coal and the squeezing of the disc body 3 and the disc shell 2; the discharged accumulated coal can be guided to the conveying belt 10 through the guide groove 41, thereby achieving the effect of balanced quantitative proportioning, and can also effectively solve the problem of the quantitative disc feeder shutting down due to excessive coal accumulation.

[0064] In some embodiments, a viewing port 12 may be provided on one side of the material guide sleeve 1, and the viewing port 12 is connected to the material discharge channel 11. The viewing port 12 can be used to observe the material accumulation in the material discharge channel 11 and the cylindrical groove 21, and timely respond to the material accumulation, reduce the possibility of accidents, and ensure the stable operation of the disc feeder and the material conveying system.

[0065] In some embodiments, the disc feeder also includes a material guide 4 connected to the disc housing 2, the material guide 4 extends above the conveyor belt 10, and the material guide 4 is provided with a material guide groove 41 connected to the coal discharge port 22, and is used to transport materials to the conveyor belt 10.

[0066] It can realize the stable collection and transportation of materials, reduce material waste, and improve the production efficiency and benefits of the material transportation system.

[0067] In some embodiments, the disc feeder can adjust the relationship between the guide sleeve 1, the disc body 3 and the disc shell 2 according to the needs. For example, the guide sleeve 1 can be located above the disc body 3, and the coal discharge port 22 can be located below the disc body 3. The disc body 3, the cylindrical groove 21 and the guide sleeve 1 can be coaxially arranged, and the axis can be arranged along the gravity direction or at an angle with the gravity direction. The disc feeder has a good use effect.

[0068] In some embodiments, the disc feeder may further include a bracket 6 and a driving mechanism 7, the bracket 6 is connected to the disc housing 2 to support the overall structure of the disc housing 2, the driving mechanism 7 may include a motor and a reducer, etc., the motor and the reducer may be transmission-connected, and the terminal output end of the driving mechanism 7 may extend into the cylindrical groove 21 and be coaxially connected to the disc body 3 to drive the disc body 3 to rotate. This facilitates the normal operation of the disc feeder.
