Description

Technical Field

[0001] This utility model relates to the field of guide plate technology, specifically to an internal guide plate for a compound fertilizer dryer. Background Technology

[0002] In compound fertilizer production, the amount of material entering the dryer is large and unevenly distributed. Guide plates can evenly distribute the material within the dryer, forming a uniform material curtain or layer. This allows hot airflow to fully penetrate the material, preventing uneven drying caused by areas of excessively thick or thin material, thus improving the consistency of drying quality. By rationally designing the shape, angle, and position of the guide plates, the material can be guided along a specific path within the dryer, increasing the contact area and contact time between the material and the hot airflow.

[0003] Existing devices primarily use spiral guide plates inside the cylinder to guide the movement of compound fertilizer. Current technologies are largely similar to guide plates and cylinders used in steam dryers. The structure disclosed in CN214120721U includes a main body and serrated filler plates distributed on the outer arc surface of the main body. The main body is a spiral-shaped plate, and several filler plates, evenly spaced along the spiral direction, are fixed on its outer arc surface, with clearance gaps between adjacent filler plates. This utility model uses filler plates on the guide plates to fill the gap between the guide plates and the inner wall of the cylinder, preventing material from being trapped and remaining inside the cylinder, thus avoiding affecting the drying quality and purity of the material. However, this device still has areas for improvement.

[0004] Existing devices mainly use integrated spiral structure guide plates, which makes it difficult to replace guide plate components that are severely deformed by local heat in some devices. This results in a lot of wasted maintenance costs and reduces the working efficiency and practicality of the device. Therefore, in order to solve the above problems, an internal guide plate for compound fertilizer dryers is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an internal guide plate for a compound fertilizer dryer, so as to solve the problem mentioned in the background art that the existing devices mainly use an integrated spiral structure guide plate, which makes it difficult to replace some guide plate components that are severely deformed by local heat, thus resulting in a lot of wasted maintenance costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an internal guide plate for a compound fertilizer dryer, comprising a cylinder, wherein heat dissipation pipes are arranged in a circular array on the inner wall of the cylinder, a spiral mounting rail is fixedly connected to the inner wall of the cylinder, guide plates are sequentially arranged on the inner wall of the spiral mounting rail, a clearance notch corresponding to the heat dissipation pipes is opened on the outer wall of the spiral mounting rail, and an assembly mechanism is provided on the spiral mounting rail.

[0007] Preferably, the spiral section of the spiral mounting rail is generally L-shaped, and the right side of the spiral mounting rail section is provided with an edge for placing the guide plate.

[0008] Preferably, the guide plate is spiral in shape, the spiral path of the guide plate is consistent with the spiral path of the spiral mounting rail, and the guide plate has one spiral turn.

[0009] Preferably, the spiral mounting rail has three sets of assembly mechanisms corresponding to each set of guide plates, and the assembly mechanisms are evenly distributed inside the spiral mounting rail.

[0010] Preferably, the assembly mechanism includes a positioning cylinder, the outer wall of which is mounted on the inner wall of the spiral mounting rail, and the inner wall of the guide plate is provided with a positioning hole that matches the positioning cylinder.

[0011] Preferably, a hexagonal bolt is inserted into the left side of the positioning cylinder, and a hexagonal threaded sleeve is threaded onto the right side of the hexagonal bolt.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model utilizes a positioning cylinder, hexagonal bolts, and hexagonal threaded sleeves in its assembly mechanism. By placing the guide plate on the inner wall of the spiral mounting rail, the positioning hole of the guide plate is fitted onto the outer wall of the positioning cylinder. Then, the guide plate is fixed by the hexagonal bolts and hexagonal threaded sleeves, thus achieving the assembly of the guide plate. This allows for the replacement of guide plates that have been severely deformed by heat in some devices, saving significant maintenance costs and improving the convenience and practicality of the device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 One embodiment provided by this utility model:

[0021] An internal guide plate for a compound fertilizer dryer includes a cylinder 11. The inner wall of the cylinder 11 has a circular array of heat dissipation pipes 12. A spiral mounting rail 13 is fixedly connected to the inner wall of the cylinder 11. Guide plates 14 are arranged sequentially on the inner wall of the spiral mounting rail 13. The outer wall of the spiral mounting rail 13 has a clearance notch 15 corresponding to the heat dissipation pipes 12. An assembly mechanism 2 is provided on the spiral mounting rail 13.

[0022] The spiral mounting rail 13 has an overall "L" shaped spiral cross-section. The right side of the spiral mounting rail 13's cross-section has an edge for mounting the guide plate 14. This design allows the spiral mounting rail 13 to overlap with the guide plate 14. The guide plate 14 is spiral in shape, and its spiral path is consistent with that of the spiral mounting rail 13. The guide plate 14 has one spiral turn. This design ensures that the outer wall of the guide plate 14 is tightly fitted to the inner wall of the spiral mounting rail 13.

[0023] The spiral mounting rail 13 has three sets of assembly mechanisms 2 corresponding to each set of guide plates 14. The assembly mechanisms 2 are evenly distributed inside the spiral mounting rail 13. Through this design, each set of guide plates 14 can be stably placed on the inner wall of the spiral mounting rail 13. The assembly mechanism 2 includes a positioning cylinder 16. The outer wall of the positioning cylinder 16 is installed on the inner wall of the spiral mounting rail 13. The inner wall of the guide plate 14 is provided with positioning holes that are compatible with the positioning cylinder 16. Through this design, each set of guide plates 14 can be positioned and placed on the inner wall of the spiral mounting rail 13. A hexagonal bolt 17 is inserted on the left side of the positioning cylinder 16. A hexagonal threaded sleeve 18 is threaded on the right side of the hexagonal bolt 17. Through this design, the guide plate 14 is fixed by limiting the position of the hexagonal bolt 17 in cooperation with the hexagonal threaded sleeve 18.

[0024] Working principle: When the guide plate 14 needs to be assembled, the guide plate 14 is first placed on the inner wall of the spiral mounting rail 13, so that the positioning hole of the guide plate 14 is fitted on the outer wall of the positioning cylinder 16. Then, the hexagonal bolt 17 is inserted into the left side of the positioning cylinder 16, and the hexagonal threaded sleeve 18 is threaded onto the right outer wall of the hexagonal bolt 17, so that the hexagonal bolt 17 cooperates with the hexagonal threaded sleeve 18 to limit and fix the guide plate 14, thus realizing the assembly operation of the guide plate 14.
