Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer processing equipment, in particular to a horizontal drum drying device. Background Art

[0002] During the processing of fertilizer, it will go through a granulation process so that the fertilizer is processed into granules, but the water content is generally very high at this time, and it needs to be dried through a drying process to reduce the water content. When drying, a drying drum can usually be used. The drying drum can generally be set to a rotating type. The material (fertilizer particles to be dried) enters the drying drum through one end, and hot air is introduced into the drying drum at the same time. The drying drum rotates so that the material is in a tumbling state and moves to the other end (to ensure smooth movement, a spiral plate can also be fixed on the inner wall of the drying drum to push the material to move to the other end during the rotation process). While tumbling, the material contacts the hot air to achieve the purpose of drying. However, in the prior art, hot air generally enters through the end of the drying drum and then is exported from the other end (generally introduced at the same end as the material), which causes the water vapor generated by drying to move to the other end together. The water vapor and the material may be mixed again in the later stage of drying, and secondary drying is required, so that the efficiency of drying will be reduced. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a horizontal drum drying device, which solves the problem in the prior art that materials need to be dried twice, resulting in low efficiency.

[0004] According to an embodiment of the utility model, a horizontal drum drying device comprises:

[0005] A horizontal fixed cylinder, with a first support box and a second support box fixedly connected at both ends, wherein the first support box is also fixedly connected to an air inlet pipe and a feed hopper, and an end of the horizontal fixed cylinder close to the second support box is also fixedly connected to an air outlet pipe;

[0006] The roller is coaxially arranged with the horizontal fixed cylinder, one end of which is located in the horizontal fixed cylinder and the other end of which is located in the first support box. The roller is rotatably matched with the horizontal fixed cylinder and is provided with a plurality of communication holes located in the horizontal fixed cylinder.

[0007] A driving motor is installed in the second supporting box and its rotating shaft is rotatably extended into the horizontal fixed cylinder and fixedly connected to the center of the end surface of the drum;

[0008] Among them: the feed hopper includes a feed section extending into the drum, the drum is also provided with an end surface hole surrounding the feed section and located in the first support box, the horizontal fixed cylinder is also fixedly connected to a discharge hopper located below it, and the drum is also provided with a plurality of discharge ports located directly above the feed hopper, and the discharge ports are located between the connecting hole and the drive motor.

[0009] In the above embodiment, the material enters one end of the drum through the feed hopper, and the hot air enters the first support box through the air inlet pipe, and then can also enter the same end of the drum, contacting the material during the rolling process to achieve drying. During the continued movement, the generated water vapor can enter the horizontal fixed cylinder through the arranged connecting hole in time, and then be discharged through the air outlet pipe, while the material leaves the drum through the discharge port and is then discharged through the discharge hopper. The probability of the material and water vapor mixing in the later stage of drying is smaller, so the frequency of the need for secondary drying of the material can be reduced, thereby improving the efficiency.

[0010] Furthermore, the air inlet pipe is arranged opposite to the end hole.

[0011] Furthermore, a plurality of first air guide holes are also arranged on the end surface of the drum where the end surface hole is arranged.

[0012] Furthermore, the horizontal fixed cylinder also includes a first support ring located in the first support box and rotatably matched with the outer wall of one end of the drum, and a second support ring located in the second support box and rotatably matched with the outer wall of the other end of the drum.

[0013] Furthermore, the first supporting ring is provided with a second air guide hole at the lower end thereof.

[0014] Furthermore, the communicating hole is a long strip-shaped hole structure.

[0015] Furthermore, the communicating holes include a plurality of hole bands distributed in an annular shape, and the hole bands are arranged at equal intervals.

[0016] Furthermore, the discharge port is a long strip-shaped hole structure equidistantly surrounding the drum.

[0017] Furthermore, the air outlet pipe is located above the horizontal fixed cylinder.

[0018] Furthermore, the first supporting box and the second supporting box are also fixedly connected with supporting legs respectively.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] By arranging a horizontal fixed cylinder outside the drum and a connecting hole on the drum, water vapor can enter the horizontal fixed cylinder through the connecting hole in time during drying, and then be discharged through the air outlet pipe, and the material is discharged through different discharge hoppers, thereby reducing the probability of water vapor and material being mixed again in the later stage of drying, and solving the problem of low efficiency caused by the need for secondary drying of materials in the prior art.

[0028] In an exemplary embodiment, Figure 1 , 2 As shown, this embodiment provides a horizontal drum drying device, which includes:

[0029] A horizontal fixed cylinder 1, with a first support box 2 and a second support box 3 fixedly connected at both ends, wherein the first support box 2 is also fixedly connected to an air inlet pipe 4 and a feed hopper 5, and an end of the horizontal fixed cylinder 1 close to the second support box 3 is also fixedly connected to an air outlet pipe 6;

[0030] The roller 7 is coaxially arranged with the horizontal fixed cylinder 1 and one end of the roller is located in the horizontal fixed cylinder 1 and the other end of the roller is located in the first support box 2. The roller 7 is rotatably matched with the horizontal fixed cylinder 1 and is provided with a plurality of communication holes 8 located in the horizontal fixed cylinder 1.

[0031] A driving motor 9 is installed in the second supporting box 3 and its rotating shaft is rotatably extended into the horizontal fixed cylinder 1 and fixedly connected to the center of the end surface of the drum 7;

[0032] Among them: the feed hopper 5 includes a feed section 10 extending into the drum 7, and the drum 7 is also provided with an end hole 11 surrounding the outside of the feed section 10 and located in the first support box 2, the horizontal fixed drum 1 is also fixedly connected to a discharge hopper 12 located below it, and the drum 7 is also provided with a plurality of discharge ports 13 located directly above the feed hopper 5, and the discharge ports 13 are located between the connecting hole 8 and the drive motor 9. When the drive motor 9 is running, it drives the drum 7 to rotate in the horizontal fixed drum 1.

[0033] In the above embodiment, the material enters one end of the drum 7 through the feed hopper 5, and the hot air enters the first support box 2 through the air inlet pipe 4, and then can also enter the same end of the drum 7. The hot air contacts the material during the rolling process to achieve drying. During the continued movement, the generated water vapor can enter the horizontal fixed cylinder 1 through the arranged connecting hole 8 in time, and then be guided away through the air outlet pipe 6, while the material leaves the drum 7 through the discharge port 13, and then is guided away through the discharge hopper 12. The probability of mixing the material and the water vapor in the latter stage of drying is smaller, so the frequency of the material needing to be dried twice can be reduced, so the efficiency is improved.

[0034] Specifically, during drying, water vapor generally moves upward relatively, and therefore accumulates at the upper part after entering the horizontal fixed cylinder 1. In order to better and quickly guide the water vapor away, the air outlet pipe 6 can be arranged above the horizontal fixed cylinder 1, and more air outlet pipes 6 can be arranged in the axial direction of the horizontal fixed cylinder 1.

[0035] Furthermore, the first support box 2 and the second support box 3 are provided to provide fixed support for both ends of the horizontal fixed cylinder 1, and are also provided for the installation of the feed hopper 5, the air inlet pipe 4 and the drive motor 9, wherein the air inlet pipe 4 can also be directly opposite to the end hole 11 on the end face of the drum 7, so that the hot air can enter the drum 7 more smoothly, and part of the hot air will also heat the end outer wall of the drum 7 in the first support box 2, thereby assisting the material in the drum 7 to dry;

[0036] Furthermore, the first support box 2 and the second support box 3 are also fixedly connected with support legs 14, respectively, so that the entire device is stable on the ground;

[0037] Furthermore, a plurality of first air guide holes 15 may be further provided on the end surface of the drum 7 where the end hole 11 is provided. These first air guide holes 15 may allow part of the hot air to enter the drum 7, thereby making the hot air enter the drum 7 more smoothly.

[0038] In a further exemplary embodiment, Figure 1 , 3As shown, the horizontal fixed cylinder 1 also includes a first support ring 16 located in the first support box 2 and the first support ring 16 is rotatably matched with the outer wall of one end of the drum 7, and a second support ring 17 located in the second support box 3 and the second support ring 17 is rotatably matched with the outer wall of the other end of the drum 7. That is, the first support ring 16 and the second support ring 17 provide rotation support for both ends of the drum 7, so that the drum 7 runs more smoothly; further, the first support ring 16 is also provided with a second air guide hole 18 located at its lower end, so that part of the hot air can enter the lower end of the horizontal fixed cylinder 1 through the second air guide hole 18, so that the lower wall of the drum 7 can be heated, thereby assisting the drying process, and at the same time, this will not cause obstruction to the movement of water vapor located relatively above.

[0039] In a more detailed exemplary embodiment, Figure 1 As shown, the communicating hole 8 includes a plurality of hole bands distributed in an annular shape, and the hole bands are arranged at equal intervals. The communicating hole 8 on each hole band can also be a long strip hole structure with a small width, which is not suitable for materials to pass through, but hot air and water vapor can pass through to ensure normal drying;

[0040] Furthermore, the discharge port 13 is a long strip-shaped hole structure equidistantly surrounding the outside of the drum 7. Compared with the connecting hole 8, the hole structure of the discharge port 13 is larger, which can allow the material to leave smoothly, and as the drum 7 rotates, the material passes through the discharge port 13 in a state of being thrown outward, so that the discharge efficiency is higher. Furthermore, the air outlet pipe 6 is staggered from the discharge port 13 to prevent the material from being thrown into the air outlet pipe 6.

[0041] 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 of the utility model, which should be included in the scope of the claims of the utility model.
