Description

Technical Field

[0001] The utility model relates to the technical field of drum granulation, in particular to a drum fluidized bed component. Background Art

[0002] Drum fluidized bed granulation technology is suitable for the production of large-particle ammonium nitrate, calcium ammonium nitrate and other compound fertilizers. This granulation technology has the characteristics of large product particle size, high particle strength, good particle roundness, not easy to agglomerate, good fluidity, simple production equipment structure, small investment, good operating environment, high degree of automation, large output of a single set of equipment, and a wide range of adjustment of process and operating conditions.

[0003] As the market demand for compound fertilizer increases, the production efficiency of drum fluidized bed granulation needs to be increased. However, as the production capacity of drum fluidized bed granulation increases, a large amount of material becomes clogged at the discharge port. The original discharge port can no longer meet the discharge requirements of the increased production capacity, resulting in a large amount of material accumulating at the discharge port, affecting production efficiency. Summary of the Invention

[0004] In view of this, the present invention provides a drum fluidized bed assembly to solve the problem that the original discharge port can no longer meet the material discharge requirements after the production capacity is increased, resulting in a large amount of material piling up at the discharge port, affecting production efficiency.

[0005] The utility model provides a drum fluidized bed assembly, comprising:

[0006] A discharge cylinder is provided at the tail end of the drum, one end of the discharge cylinder is fixedly connected to the tail end of the drum, and the discharge cylinder is coaxially arranged with the drum;

[0007] A material guiding structure is arranged on the inner wall of the discharge barrel, and the material guiding structure includes a guiding portion. The material guiding structure is suitable for rotating with the discharge barrel so that the guiding portion guides the material in the discharge barrel to discharge the discharge barrel.

[0008] Beneficial effects:

[0009] The material guiding structure is arranged on the inner wall of the discharge barrel and rotates with the discharge barrel. The material guiding structure includes a guiding part. When the discharge barrel rotates, the guiding part can guide the material at the bottom of the discharge barrel to discharge the discharge barrel. By setting the material guiding structure, the discharge speed of the discharge barrel can be increased to meet the discharge speed of the drum fluidized bed after the production capacity is increased.

[0010] In an optional embodiment, the material guiding structure further includes a bearing portion, and when the bearing portion rotates to a first position along with the discharge barrel, the bearing portion is suitable for bearing the material in the discharge barrel, and when the bearing portion rotates from the first position to the second position along with the discharge barrel, the bearing portion is suitable for conveying the material to the guiding portion.

[0011] Beneficial effects:

[0012] The bearing part rotates with the discharge barrel. When the bearing part rotates to the first position, the material in the discharge barrel can be accommodated in the bearing part. As the bearing part rotates to the second position, the bearing part transports the accommodated material to the guide part, and discharges the material out of the discharge barrel through the guide part. While the discharge barrel discharges the material by rotating, the bearing part and the guide part cooperate to discharge the material out of the discharge barrel through the guide part, thereby improving the discharge efficiency.

[0013] In an optional embodiment, one side of the bearing portion is connected to one side of the guide portion, and the connection between the bearing portion and the guide portion has an angle. In the first position, the guide portion and the bearing portion cooperate to accommodate materials.

[0014] Beneficial effects:

[0015] The connection between the load-bearing part and the guide part has an angle. When the load-bearing part rotates from the first position to the second position, the material contained in the load-bearing part will be blocked by the guide part to prevent the material contained in the load-bearing part from falling from the load-bearing part and affecting the discharge efficiency.

[0016] In an optional embodiment, it further includes: a plurality of material nozzles, and the plurality of material nozzles are arranged at intervals in the drum.

[0017] In an optional embodiment, the material nozzle has a groove extending in a horizontal direction at one end of the nozzle hole, and the cross section of the groove is conical.

[0018] Beneficial effects:

[0019] A groove is provided at one end with a spray hole. The groove having a conical cross section can increase the flow rate of the spray hole, thereby effectively improving the production capacity.

[0020] In an optional embodiment, the width of the groove gradually decreases from the middle to both ends.

[0021] Beneficial effects:

[0022] By designing the groove to have a structure with gradually decreasing width from the middle to the two ends, the flow rate can be increased while the sprayed material liquid can fully contact with the air and quickly cool and solidify, preventing the problem of the material liquid not being able to fully contact with the air and unable to solidify quickly due to the increase in flow rate.

[0023] In an optional embodiment, at least one material guiding structure is provided in the discharge barrel.

[0024] Beneficial effects:

[0025] By arranging multiple material guiding structures in the discharge barrel, the discharge efficiency of the discharge barrel can be effectively improved, which helps to improve production efficiency.

[0026] In an optional embodiment, the angle between the bearing portion and the guiding portion is 120°-150°.

[0027] In an optional embodiment, the angle of the bottom of the groove is 75°. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0036] As the market demand for compound fertilizers increases, it is necessary to increase the production efficiency of drum fluidized bed granulation to meet the market demand for compound fertilizers. However, after increasing the production capacity of the drum fluidized bed, a large amount of material was unable to be discharged through the discharge port, and a large amount of material was blocked at the discharge port, resulting in low discharge efficiency at the discharge port. The discharge barrel has a 3° slope. As the discharge barrel rotates, the material entering the discharge barrel will be discharged from the discharge barrel along the 3° slope. As the production capacity of the drum fluidized bed increases, a large amount of material enters the discharge barrel. The 3° slope of the discharge barrel is unable to discharge a large amount of material, resulting in blockage and accumulation.

[0037] The present application sets a material guiding structure on the inner wall of the discharge barrel 1, which can guide and discharge the material in the discharge barrel 1. The material guiding structure cooperates with the 13° slope of the discharge barrel to discharge a large amount of material entering the discharge barrel 1 into the discharge barrel 1, thereby improving the discharge efficiency and further improving the production efficiency.

[0038] The following combination Figures 1 to 4 , describing the embodiments of the present utility model.

[0039] According to an embodiment of the present utility model, a drum fluidized bed assembly device is provided, comprising: a discharge cylinder 1 and a material guiding structure.

[0040] Specifically, a discharge barrel 1 is disposed at the rear end of the drum, one end of which is fixedly connected to the rear end of the drum, and the discharge barrel 1 and the drum are coaxially disposed. A material guide structure is disposed on the inner wall of the discharge barrel 1 and includes a guide portion 2. The material guide structure is adapted to rotate with the discharge barrel 1 so that the guide portion 2 guides the material in the discharge barrel 1 to be discharged from the discharge barrel 1.

[0041] In this embodiment, the tail end of the drum is the material discharge port, and the discharge barrel 1 is fixedly connected to the tail end of the drum. The rotation of the drum drives the discharge barrel 1 to rotate. The rotation of the drum can transport the material in the drum into the discharge barrel 1, and the rotation of the discharge barrel 1 can discharge the material entering the discharge barrel 1. The material guide structure is provided on the inner wall of the discharge barrel 1. The material guide structure includes a guide part 2. The guide part 2 rotates with the discharge barrel 1. When the guide part 2 rotates, it can guide the material at the bottom of the discharge barrel 1 and guide it from the inside of the discharge barrel 1 to the outside of the discharge barrel 1.

[0042] like Figure 1 and Figure 2 As shown, in some embodiments, the material guiding structure further includes a supporting portion 3. When the supporting portion 3 rotates to the first position along with the discharge barrel 1, the supporting portion 3 is suitable for supporting the material in the discharge barrel 1. When the supporting portion 3 rotates from the first position to the second position along with the discharge barrel 1, the supporting portion 3 is suitable for conveying the material to the guiding portion 2.

[0043] In this embodiment, the material guiding structure also includes a bearing part 3, which is arranged on the side of the guide part 2 facing the roller. The bearing part 3 can rotate with the discharge barrel 1. The bearing part 3 is a plate-like structure. When the bearing part 3 is in the first position, the bearing part 3 is located at the bottom of the barrel. At this time, the bearing part 3 is perpendicular to the horizontal plane. As the discharge barrel 1 rotates, the bearing part 3 can carry part of the material located at the bottom of the discharge barrel 1 to the end face of the bearing part 3. The bearing part 3 cooperates with the inner wall of the discharge barrel 1 to accommodate the material at the angle between the bearing part 3 and the discharge barrel 1. In the second position, the bearing part 3 is parallel to the horizontal direction. In the process of the bearing part 3 rotating from the first position to the second position, the material accommodated in the bearing part 3 will roll and roll along the bearing part 3 to the guide part 2. The guide part 2 guides the material to the outside of the discharge barrel 1.

[0044] In addition, in other embodiments, except for the side facing the guide portion 2 and the side fixedly connected to the discharge barrel 1, the other side edges of the support portion 3 are all provided with bending portions. The bending portions can enable the support portion 3 to better support the material and prevent the material from falling from the end face of the support portion 3 during the rotation of the support portion 3.

[0045] In other embodiments, when the load-bearing portion 3 is in the first position, the load-bearing portion 3 is perpendicular to the horizontal plane; when in the second position, there is an angle between the load-bearing portion 3 and the horizontal plane; the load-bearing end surface of the load-bearing portion 3 is constructed as an inclined surface inclined toward the guide portion 2; in the process of the load-bearing portion 3 rotating from the first position to the second position, the material on the load-bearing portion 3 can be guided to the guide portion 2 through the inclined surface, and the inclined surface can better guide the material.

[0046] That is to say, by setting up the bearing part 3, part of the material accumulated at the bottom of the discharge barrel 1 can be carried on the bearing part 3, and the bearing part 3 transports the carried material to the guide part 2 during the rotation, and the material is discharged from the discharge barrel 1 through the guide part 2. During the rotation of the discharge barrel 1, it can not only discharge the material through its own 3° inclined surface, but also discharge part of the material through the bearing part 3 and the guide part 2.

[0047] like Figure 1 and Figure 2 As shown, in some embodiments, one side of the bearing portion 3 is connected to one side of the guide portion 2, and the connection between the bearing portion 3 and the guide portion 2 has an angle. In the first position, the guide portion 2 and the bearing portion 3 cooperate to accommodate materials.

[0048] In this embodiment, the bearing portion 3 and the guide portion 2 are both plate-shaped structures. Figure 1In the figure, the bearing part 3 is arranged on the rear side of the guide part 2, and the front side of the bearing part 3 is connected to the rear side of the guide part 2. The material on the bearing part 3 is discharged from the front side of the guide part 2 to the discharge barrel 1. The bearing part 3 and the guide part 2 are fixedly connected to form a material guiding structure. The connection between the bearing part 3 and the guide part 2 has an angle, and the upper end face of the guide part 2 is an inclined surface to facilitate the discharge of the material carried on the bearing part 3 to the discharge barrel 1 through the inclined surface. When the bearing part 3 is in the first position, the guide part 2 can cooperate with the bearing part 3 to carry the material to the end face of the bearing part 3. The guide part 2 can prevent the material from falling from the bearing part 3. The guide part 2, the inner wall of the discharge barrel and the bearing part 3 cooperate to accommodate the material.

[0049] In addition, in other embodiments, Figure 1 In the figure, a bending portion can be provided on the right side of the guide portion 2, which can block the material. When in the first position, the bending portion can prevent the material from falling from the load-bearing portion 3. At the same time, in the process of the material rolling from the load-bearing portion 3 to the guide portion 2, the bending portion can prevent the material from falling from the guide portion 2 into the discharge barrel 1, thereby reducing the discharge efficiency. The bending portion can guide and limit the material, and guide the material to be discharged from the front side of the guide portion 2 to the discharge barrel 1.

[0050] like Figure 2 As shown, in some embodiments, at least one material guiding structure is provided in the discharge barrel 1 .

[0051] In this embodiment, two material guiding structures are provided in the discharge barrel 1. The two material guiding structures are symmetrically arranged with respect to the center of the discharge barrel 1. The two material guiding structures can cooperate with the 13° slope of the discharge barrel, so that a large amount of material entering the discharge barrel 1 can be discharged into the discharge barrel 1.

[0052] In other embodiments, three, four or other numbers of material guiding structures may be provided in the discharge barrel 1 , and the plurality of material guiding structures may be provided at intervals or at even intervals.

[0053] In some embodiments, the angle between the bearing portion 3 and the guiding portion 2 is 120°-150°.

[0054] In this embodiment, the angle between the bearing portion 3 and the guide portion 2 is 135°, and the angle between the guide portion 2 and the inner wall of the discharge barrel 1 is 45°. In other embodiments, the angle between the bearing portion 3 and the guide portion 2 may be 120°, 150° or other angles.

[0055] To increase the production capacity of the drum fluidized bed, this embodiment further provides a material nozzle 4. By installing the material nozzle 4 disclosed in this embodiment within the drum fluidized bed, the material flow rate can be increased, thereby increasing the production capacity of the drum fluidized bed. The material nozzle 4 and the aforementioned material guide structure can effectively increase the production efficiency of the drum fluidized bed. The specific structure of the material nozzle 4 is described in detail below.

[0056] like Figure 3 and Figure 4 As shown, in some embodiments, it also includes: a plurality of material nozzles 4, and the plurality of material nozzles 4 are arranged in the drum at intervals.

[0057] like Figure 3 As shown, in some embodiments, the material nozzle 4 has a nozzle hole 5 and one end thereof is provided with a groove 6 extending in a horizontal direction, and the cross section of the groove 6 is conical.

[0058] like Figure 3 As shown, in some embodiments, the groove 6 is concentrically arranged with the spray hole 5 , and the spray hole 5 is arranged in the groove 6 .

[0059] In this embodiment, a groove 6 is provided on the end face of the material nozzle 4 having the spray hole 5, both ends of the groove 6 extend to the edge of the end face, the cross section of the groove 6 is conical, the spray hole 5 is arranged in the groove 6 and is located at the bottom of the groove 6, the spray hole 5 is arranged in the middle of the groove 6, and the spray hole 5 is concentrically arranged with the groove 6. When the spray hole 5 sprays the material, the material will first enter the groove 6 through the spray hole 5 and then be sprayed into the drum. The groove 6 can increase the flow rate of the spray hole 5 and improve the spraying efficiency.

[0060] like Figure 3 As shown, in some embodiments, the width of the groove 6 gradually decreases from the middle to both ends.

[0061] In this embodiment, the width of the middle part of the groove 6 is greater than the width of the two ends of the groove 6, and the width gradually decreases from the middle part to the two ends. The material flow rate at the two ends of the groove 6 is less than the flow rate in the middle part of the groove 6. The purpose is to make the material sprayed from the two ends of the groove 6 fully contact with the air. If the flow rate at the two ends of the groove 6 is the same as the flow rate in the middle part of the groove 6, the material sprayed from the two ends of the groove 6 will not be able to fully contact with the air, resulting in the material being unable to quickly condense into a solid state. The semi-solid material will stick to other materials to form a block structure, which is easy to accumulate in the drum, which is not conducive to subsequent production.

[0062] It should be noted that the material sprayed from the spray hole 5 is in liquid form, and there is a distance between the spray hole 5 and the bottom of the drum. The sprayed material will quickly condense into a solid state when it comes into contact with the air during the falling process.

[0063] like Figure 3 As shown, in some embodiments, the angle of the bottom of the groove 6 is 75°.

[0064] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
