Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery and utilization technology in fertilizer production, and in particular to a filter-type pipeline screen device for fertilizer production. Background Technology

[0002] In the fertilizer production sector, the quality of particle filtration during material transport directly impacts product quality and production continuity. Fertilizer materials are complex and diverse: organic fertilizer production often involves solid impurities such as straw fragments, clumps of livestock and poultry manure, and bone meal residue; during compound fertilizer preparation, unreacted phosphate rock powder, potassium salt crystals, and large particles missed during raw material screening can easily enter the transport pipelines. If these impurities exceeding particle size limits are not intercepted in time, they can cause multiple production problems: clogging granulator nozzles leading to uneven particle formation, wear on conveyor impellers increasing equipment maintenance costs, and even affecting the nutrient uniformity of subsequent products, reducing fertilizer application effectiveness. Existing pipeline filters are mostly designed for fluid media and are difficult to adapt to the characteristics of particulate materials in fertilizer production: conventional filter screens have fixed pore sizes, which are prone to clogging due to particle accumulation, requiring frequent shutdowns for cleaning and causing production interruptions; the few filtration devices designed for solid materials suffer from complex structures and inconvenient disassembly, resulting in insufficient adaptability and practicality. With the increasing demands for fertilizer quality in modern agriculture and the need for high efficiency and stability in large-scale production, there is an urgent need for a dedicated pipeline filtration device that can accurately intercept large particulate impurities, is easy to clean and maintain, and is suitable for the transportation of particulate media, in order to solve the application pain points of traditional equipment.

[0012] Figure 1 This is a schematic diagram of a filter-type pipeline screen device for fertilizer production. Figure 2 for Figure 1 A schematic diagram of the structure of the middle screen from the left. Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1 and 2 As shown, a filter-type pipeline screen device for fertilizer production includes a housing 1. The top of the housing 1 is connected to the fertilizer pipeline material inlet 2, and the bottom of the housing 1 is connected to the fertilizer pipeline material outlet 3. A detachable screen 4 is obliquely arranged inside the housing 1. The bottom extension of the screen 4 has a discharge port 5, and the area below the screen 4 is connected to the fertilizer pipeline material outlet 3. The screen 4 includes multiple upper grooves 4.1 on the upper side and multiple lower grooves 4.2 on the lower side. A round steel bar 4.3 is placed between each upper groove 4.1 and lower groove 4.2. The grooves 4.2 are detachably connected. In this embodiment, the number of round steel bars 4.3 can be increased or decreased between the upper grooves 4.1 and lower grooves 4.2, thereby adjusting the spacing between adjacent round steel bars 4.3. This allows for free adjustment of the particle agglomerate diameter that the screen 4 can filter, adapting to actual production needs.

[0015] Preferably, the housing 1 has a spindle-shaped structure that is narrow at the top and bottom and wide in the middle.

[0016] Preferably, the two ends of the round steel bar 4.3 are detachably connected to the upper groove 4.1 and the lower groove 4.2 by bolts. In this embodiment, the round steel bar 4.3 constituting the screen 4 is detachable, so the number of round steel bars 4.3 can be increased or decreased more easily, and the spacing between adjacent round steel bars 4.3 can be adjusted. Its function is to freely adjust the diameter of the particle clusters that the screen 4 can filter, so as to adapt to the actual production needs.

[0017] Preferably, the upper groove 4.1 and the lower groove 4.2 are steel strip structures formed by continuous S-shaped bends to create multiple grooves. This steel strip structure is easy to process. In actual installation, it is only necessary to place the round steel 4.3 between the upper groove 4.1 and the lower groove 4.2 and then tighten the bolts.

[0018] Preferably, an inspection port 1.1 is provided on the surface of the housing 1 above the side of the screen 4, and an inspection door 1.2 is hinged to the inspection port 1.1. When it is necessary to adjust the spacing between the round steel bars 4.3, the inspection door 1.2 can be opened, thereby adjusting the spacing between the round steel bars 4.3 at the inspection port 1.1.

[0019] Preferably, a valve 5.1 is provided at the discharge port 5. When a large number of large particles accumulate at the discharge port 5, the valve 5.1 can be opened to discharge the material.

[0020] Preferably, a vibration motor 5.2 is also provided below the discharge port 5. Turning on the vibration motor 5.2 can increase the speed at which material is discharged from the discharge port 5.

[0021] The working principle of this embodiment is as follows: In this device, materials are conveyed pneumatically through pipelines. The material consists of particles with a diameter of approximately 1-5 mm. During production, these particles tend to agglomerate, forming larger agglomerates with a diameter exceeding 50 mm. These larger agglomerates are conveyed through the pipeline to the crusher for crushing. However, even larger agglomerates are generated during production, preventing them from reaching the crusher via pneumatic conveying. These agglomerates accumulate at the bottom of the pipeline, causing blockages and increasing the load on the crusher. Therefore, an auxiliary filter based on a Y-type filter was manufactured. Figure 1 The filter-type pipe screen shown.

[0022] The material enters through the fertilizer pipe material inlet 2 above the shell 1. After passing through the screen 4, large particles larger than the distance between two adjacent round steel bars 4.3 are intercepted. These intercepted large particles, under the influence of gravity, gather along the inclined screen 4 to the discharge port 5 on one side of the shell 1. The screen 4 is constructed as follows... Figure 2As shown, the screen 4 consists of upper grooves 4.1 and lower grooves 4.2 on the upper and lower sides, and round steel bars 4.3. The spacing between the upper grooves 4.1 and the spacing between the lower grooves 4.2 are the same. The surface of the round steel bars 4.3 is smooth, which is conducive to filtration. At the same time, large particles intercepted can more easily gather along the inclined screen 4. The round steel bars constituting the screen 4 are detachable, and the number of round steel bars 4.3 can be increased or decreased, and the spacing between adjacent round steel bars 4.3 can be adjusted. Its function is to freely adjust the diameter of the particle clusters that the screen 4 can filter, so as to adapt to actual production needs. The filtered large particle clusters can be temporarily stored above the valve 5.1 of the discharge port 5. By periodically opening the valve 5.1, the large particles can be discharged. Due to the pneumatic conveying, the shell 1 is in a negative pressure state, and the material flow is not affected. The large particle clusters can be discharged smoothly under the action of gravity. The material after passing through the screen 4 gathers in the funnel part below and can flow smoothly to the next production stage through the fertilizer pipeline material outlet 3.

[0023] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
