[0002] Coal quantitative disc feeder is a commonly used quantitative coal blending equipment in coking plants. It has a simple structure and is easy to maintain. 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, one end of the guide sleeve extends to the end face of the disc body, and the side wall of the guide sleeve is provided with a guide port extending to the end face of the disc body. The disc shell is higher than the disc body and has a discharge port on the side. The material entering the guide sleeve falls to the disc body, is output from the guide port as the disc body rotates, and then enters the discharge port of the disc shell from the guide port. The material flows out from the guide port of the guide sleeve. When the material continues to fall, the material is easy to accumulate in the guide sleeve and is difficult to enter the discharge port from the guide port. Too much material accumulates in the disc feeder, causing the disc feeder to shut down due to overload, affecting production efficiency. Utility Model Content

[0031] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0032] 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:

[0033] The disc housing 2 is provided with a cylindrical groove 21 and a discharge port 22 . The discharge port 22 is provided at the side of the disc housing 2 and communicates with the side wall of the cylindrical groove 21 .

[0034] The material guiding sleeve 1 comprises a connected cylindrical portion 11 and a material guiding portion 12. The two ends of the cylindrical portion 11 are respectively a connecting end 111 and a material guiding end 112. The connecting end 111 is used to communicate with the silo to receive the material. The material guiding end 112 is inserted into the cylindrical groove 21 and is provided with a material guiding port 1121 connected to its own inner wall. The material guiding port 1121 is opposite to the material discharge port 22, and the height of the material guiding port 1121 is greater than the height of the material discharge port 22. At least two material guiding portions 12 are respectively located on both sides of the material guiding port 1121 and extend toward the material discharge port 22.

[0035] The disc body 3 is rotatably disposed on the disc housing 2 and is located in the cylindrical groove 21 . The end surface of the disc body 3 is in sliding contact with the material guide end 112 .

[0036] The cylindrical groove 21 of the disc shell 2 of the disc feeder provides a matching space for the material guide sleeve 1 and the disc body 3. The discharge port 22 arranged on the side of the disc shell 2 and connected to the side wall of the cylindrical groove 21 is used to transport materials. The two ends of the cylindrical portion 11 of the material guide sleeve 1 are respectively a connecting end 111 and a material guide end 112. The connecting end 111 can be connected to the silo to receive the material falling from the silo. The material guide end 112 inserted into the cylindrical groove 21 can cooperate with the disc body 3 rotatably set in the cylindrical groove 21, and slide with the end surface of the disc body 3. When the disc body 3 rotates relative to the disc shell 2 and the cylindrical portion 11, the disc body 3 can push the material in the cylindrical portion 11 out of the cylindrical portion 11 through the guide port 1121 connected to the inner wall of the cylindrical portion 11 through the guide end 112 of the cylindrical portion 11. The guide sleeve 1 is connected to the cylindrical portion 11 and has at least two guide portions 12 respectively located on both sides of the guide port 1121. The guide portion 12 extends toward the discharge port 22, so that the material pushed out of the guide port 1121 moves toward the discharge port 22 set in the disc shell 2, and moves from the discharge port 22 to the corresponding equipment, etc. The material guide port 1121 is opposite to the material discharge port 22, and the height of the material guide port 1121 is greater than that of the material discharge port 22, which can increase the amount of material that can be output by the material guide port 1121 and reduce the possibility of material being blocked in the cylindrical portion 11. The material guide portion 12 can also effectively move the material to the material discharge port 22 for output, which can reduce the possibility of material accumulation in the material guide sleeve 1, and facilitate the material to flow out of the material guide port 1121 and then enter the material discharge port 22 for output, thereby reducing the possibility of excessive accumulation of material in the disc feeder, causing the disc feeder to shut down due to overload, ensuring the normal production of the disc feeder to improve production efficiency, and to a certain extent solving the technical problem of the disc feeder's production efficiency being affected.

[0037] It should be noted that the height involved in this application is the height relative to the ground or reference plane when the disc feeder is in normal use. It can also be based on the end face of the disc body 3, and the maximum height of the guide port 1121 relative to the maximum height of the end face of the disc body 3. The material in the silo directly enters the inner hole of the cylindrical part 11 through one end of the cylindrical part 11. 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.

[0038] For ease of understanding, the structure of the disc body 3 is described here. The disc body 3 is a disc-shaped structure with a groove on the plate surface. When the disc body 3 rotates relative to the disc shell 2, the uneven arrangement between the groove and the plate surface of the disc can drive and push the material and make the material flow out from the discharge port 22. The disc shell 2 can be similar to a cylinder, and both ends are closed or converged, so that the internal space of the disc shell 2 forms a cylindrical groove 21.

[0039] In some embodiments, the discharge port 22 extends to the opening of the cylindrical groove 21 , and the maximum height of the guide port 1121 is greater than the opening height of the cylindrical groove 21 .

[0040] The discharge port 22 extends to the opening of the cylindrical groove 21, and can accept more materials. The maximum height of the material guide port 1121 is greater than the opening height of the cylindrical groove 21, that is, the maximum height of the material guide port 1121 is greater than the maximum height of the discharge port 22, which can more effectively increase the material that can flow out of the material guide port 1121 and reduce the possible blockage of the cylindrical portion 11.

[0041] In some embodiments, the axes of the cylindrical groove 21 and the disc body 3 extend in the same direction, and the ratio of the distance between the guide port 1121 and the end face and the distance between the opening of the cylindrical groove 21 and the end face is 5:3 to 1:1, based on the end face of the disc body 3. When the disc feeder is working normally, based on the end face of the disc body 3, the distance between the guide port 1121 and the end face is the height of the guide port 1121 relative to the end face of the disc body 3, and the height of the cylindrical groove 21 relative to the end face of the disc body 3. When the ratio of the two distances or heights is within the above range, the efficiency of the rotation and transportation of the material is high, and the possible blockage of the material can be effectively reduced.

[0042] It should be noted that the end face of the disc body 3 can be any end face at both axial ends of the disc body 3, and this application does not impose any limitation on this.

[0043] In some embodiments, the distance between the guide port 1121 and the end surface may be 105 mm to 110 mm, and the distance between the opening of the cylindrical slot 21 and the end surface may be 60 to 100 mm. It can be applied to most disc feeders and has good versatility.

[0044] In some embodiments, the two guide portions 12 are respectively located on both sides of the guide port 1121 and extend to the discharge port 22. The material flowing out of the guide port 1121 can be stably guided to the discharge port 22 for output, thereby reducing the possible blockage of the material in the cylindrical portion 11.

[0045] In some embodiments, in the direction from the axis of the cylindrical portion 11 to the peripheral wall of the cylindrical portion 11 , the distance between the two material guide portions 12 decreases, and the minimum distance between the two material guide portions 12 is smaller than the width of the discharge port 22 .

[0046] The spacing between the two guides 12 decreases in the direction from the axis of the cylindrical portion 11 to the peripheral wall of the cylindrical portion 11. The rotational thrust exerted on the material by the disc body 3 and the centrifugal force of part of the material can promote the material to enter the discharge port 22, improve the material conveying efficiency, and also help to reduce the possibility of material blockage and improve the production efficiency of the disc feeder. The minimum spacing between the two guides 12 is smaller than the width of the discharge port 22, which can also allow part of the material located between the cylindrical portion 11 and the cylindrical groove 21 to have space to enter the discharge port 22, which is conducive to reducing the overall material accumulation.

[0047] In some embodiments, the distance between the two material guiding portions 12 may also remain unchanged, and the present application does not impose any limitation on this.

[0048] In some embodiments, along the axial direction of the cylindrical portion 11, the material guiding portion 12 extends from the material guiding end 112 to the highest point of the material guiding port 1121, so that the material flowing out of the material guiding port 1121 can be effectively guided.

[0049] In some embodiments, the material guide portion 12 may be plate-shaped, and the highest point of the material guide port 1121 corresponds to the maximum height of the material guide port 1121. The maximum height of the material guide plate may also be greater than the material guide port 1121, or less than the material guide port 1121. Compared with the background scheme, the guidance and transportation of materials can be improved.

[0050] Combination Figure 1 and Figure 2 In some embodiments, there is a spacing between the cylindrical portion 11 and the side wall of the cylindrical groove 21. The disc feeder also includes a booster 4, which is detachably connected to the outer peripheral wall of the cylindrical portion 11 and is located in a space corresponding to the spacing. The booster 4 is spaced apart from the disc body 3.

[0051] There is a gap between the cylindrical portion 11 and the side wall of the cylindrical groove 21. The booster 4 is arranged in the space corresponding to this gap, and the booster 4 is spaced from the disc body 3. The booster 4 can apply pressure to the material flowing into the cylindrical portion 11 and the disc housing 2, and when the material contacts the booster 4, it can remind the staff that the material accumulation of the disc feeder is serious and needs to be handled. The booster 4 itself can increase the downward pressure on the material so that the material can be driven to the discharge port 22 by the rotating disc body 3.

[0052] It should be noted that Figure 2 The left side figure is a partial schematic diagram of the right side figure, and the left side figure does not show the disc housing 2. Figure 2 The right side of the figure only shows the shell body 23 below the booster 4. In the disc feeder, there is usually a gap between the guide end 112 of the cylindrical part 11 and the end face of the disc body 3 to meet the requirement of the disc body 3 rotating relative to the disc shell 2 and the cylindrical part 11. A gap can also be set between the outer peripheral wall of the cylindrical part 11 and the cylindrical groove 21 to provide an operating space for processing the material. The materials located in the space corresponding to the gap can also be pressurized by the booster 4 and cooperate with the disc body 3 to flow out from the discharge port 22.

[0053] In some embodiments, the distance between the booster 4 and the disc body 3 changes gradually along the circumference of the cylindrical portion 11 . With the disc body 3 rotating counterclockwise or clockwise, different pressures are applied to the material in the circumference of the cylindrical portion 11 to promote the material to enter the discharge port 22 .

[0054] In some embodiments, the booster 4 is an acrylic arc plate, and the inner circumferential wall of the acrylic arc plate is closely connected to the outer circumferential wall of the cylindrical portion 11. The acrylic arc plate is usually translucent or transparent, and the arc shape can match the rotation of the disc body 3, facilitate the detection of the material condition, and fully apply pressure to the material to promote the material to be driven into and out of the material port 22.

[0055] In some embodiments, the disc feeder further comprises:

[0056] The columnar member 5 is inserted into the booster member 4 along the axial direction of the cylindrical portion 11 .

[0057] The elastic member 8 is coaxially sleeved on the columnar member 5 , and two ends of the elastic member 8 act on the columnar member 5 and the booster member 4 respectively.

[0058] The columnar member 5 cooperates with the elastic member 8, and the elastic member 8 can play a shock-absorbing role when the material presses against the supercharging member 4, thereby extending the overall life. The elastic member 8 can also provide a certain operating space for the columnar member 5.

[0059] In some embodiments, the booster 4 can also be set as a rectangular plate or a plate of other shapes according to needs. The booster 4 is detachably connected to the outer peripheral wall of the cylindrical part 11, and the connection can be achieved by snaps or fasteners, etc., which is convenient for overall disassembly and assembly. The elastic member 8 can be an annular elastic member or spring sleeved on the cylindrical member 5, and the expansion and contraction direction of the elastic member 8 can be along the axial direction of the cylindrical part 11. One end of the elastic member 8 can be fixed to the cylindrical member 5, or it can only abut on the annular protruding ring provided on the cylindrical member 5, or the disc feeder can also include a nut threadedly connected to the cylindrical member 5, one end of the elastic member 8 can abut against the cylindrical member 5 and the nut, and the elastic member 8 can be located on a plate surface of the acrylic arc plate away from the disc body 3. Convenient for operation.

[0060] In some embodiments, the disc housing 2 includes a housing body 23 and a discharge barrel 24. The inner hole of the discharge barrel 24 is arranged along the gravity direction of the axis of the disc housing 2 and can be configured as a discharge port 22 to facilitate the transportation of materials. Other structures and effects in the disc feeder can be referred to above and will not be repeated here. The discharge port 22 can transfer materials to equipment such as a conveyor belt.

[0061] In some embodiments, an observation port 13 may be provided on one side of the material guide sleeve 1. The observation port 13 may be set on the cylindrical portion 11. The observation port 13 can facilitate observation of material discharge conditions, timely response to material accumulation conditions, reduce the possibility of accidents, and ensure stable operation of the disc feeder and the material conveying system.

[0062] In some embodiments, the disc feeder can adjust the relationship between the guide sleeve 1, the disc body 3 and the disc housing 2 according to the needs. For example, the guide sleeve 1 can be located above the disc body 3, and 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 better use effect.

[0063] 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.
