Description

Technical Field

[0001] This utility model relates to the field of granulator head technology, and in particular to the structure of an anti-clogging compound fertilizer granulator head. Background Technology

[0002] In existing technologies, the compound fertilizer granulator head is a key piece of equipment in the compound fertilizer production process, playing an important role in granulation efficiency and product quality.

[0003] However, existing compound fertilizer granulator heads have many problems in the material conveying process. On the one hand, materials tend to accumulate in the conveying pipe, especially at the discharge port inside the granulator head, which easily leads to blockage. Existing granulator heads lack effective anti-blocking structures, resulting in frequent shutdowns for cleaning, which not only reduces production efficiency but also increases manual maintenance costs. On the other hand, even if some granulator heads are equipped with simple cleaning structures, the cleaning effect is poor, and they cannot effectively remove materials adhering to the inner wall of the conveying pipe and near the discharge port. Long-term use will still cause blockages, affecting the continuity and stability of the granulation process.

[0004] Therefore, it is necessary to provide an anti-clogging compound fertilizer granulator head structure to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides an anti-clogging compound fertilizer granulator head structure, which solves the problems in the background art.

[0006] To solve the aforementioned technical problems, the anti-clogging compound fertilizer granulator head structure provided by this utility model has a main body as its core, with a conveying pipe installed through one end to form a material conveying channel. A mounting frame is fixed to the surface of the main body, and a vertical support rod is installed on the mounting frame. The top of the support rod is connected to the surface of the gas storage tank in the pulse air jet assembly, ensuring stable installation of the gas storage tank. The output end of the gas storage tank is connected to a jet pipe, one end of which is connected to the conveying pipe at a 30-degree angle. An electromagnetic pulse valve is installed on the surface of the conveying pipe to control the process of the gas storage tank spraying gas into the conveying pipe through the jet pipe. In this structure, the gas storage tank, jet pipe, electromagnetic pulse valve, and conveying pipe cooperate with each other. Under the control of the electromagnetic pulse valve, the gas stored in the gas storage tank is sprayed into the conveying pipe at a specific angle through the jet pipe, impacting the material and preventing blockage of the discharge hole inside the main body of the granulator head.

[0007] Preferably, a main shaft is installed inside the conveying pipe, with one end connected to the granulator drive to obtain rotational power. A spiral impeller is installed on the circumferential side of the main shaft to push the material; simultaneously, multiple mounting plates are installed on the circumferential side of the main shaft, located on one side of the spiral impeller, with the mounting plates evenly distributed around the main shaft. A wire brush is installed at the top of each mounting plate, with one end of the wire brush contacting the inner wall of the conveying pipe. When the main shaft rotates, the spiral impeller pushes the material, and the wire brush rotates synchronously to clean the inner wall of the conveying pipe, preventing material adhesion. The two work together to ensure smooth material conveying.

[0008] Preferably, the machine head body and the conveying pipe are connected by a spiral connection. This connection method facilitates installation and disassembly, makes it convenient to inspect and maintain internal parts, and ensures the stability of the connection, so as to prevent leakage and other problems during material conveying.

[0009] Preferably, the multiple mounting plates are installed around the side of the main shaft, so that the wire brush can cover the inner wall of the conveying pipe in all directions, clean the inner wall of the conveying pipe without dead angles, further improve the anti-clogging effect, and ensure the stable conveying of materials in the conveying pipe.

[0010] Preferably, the top of the vertically mounted support rod on the mounting bracket is fixed to the surface of the gas tank, providing stable support for the gas tank and ensuring that the position of the gas tank is fixed during operation, so that the jet pipe can stably jet into the delivery pipe and play the role of the pulse air jet component in preventing blockage.

[0011] Preferably, the main body of the pelletizing head is equipped with a corresponding controller, which can control components such as electromagnetic pulse valves, adjust parameters such as the jet frequency and duration of the pulse air jet component according to actual working needs, and monitor the working status of the entire pelletizing head to achieve intelligent control and ensure efficient and stable operation of the pelletizing head.

[0012] Compared with related technologies, the anti-clogging compound fertilizer granulator head structure provided by this utility model has the following beneficial effects: Compared to existing technologies, this method utilizes a pulse air jet assembly mounted on the main body of the die head. The air tank is connected to the conveying pipe at a 30-degree angle via a jet pipe and is equipped with an electromagnetic pulse valve. During operation, the electromagnetic pulse valve controls the air tank to jet air into the conveying pipe in a pulsed manner. The 30-degree angle design allows the airflow to precisely impact the inside of the conveying pipe and the discharge port at a specific angle, quickly dispersing accumulated materials. This effectively prevents material blockage at the discharge port inside the die head, reducing downtime caused by blockages and significantly improving the continuity and efficiency of compound fertilizer granulation production.

[0013] Compared with existing technologies, a main shaft connected to the granulator drive is installed inside the conveying pipe. The spiral pusher impeller on the main shaft can push the material. At the same time, the wire brush on the mounting plate on one side of the impeller contacts the inner wall of the conveying pipe. During the rotation of the main shaft, the wire brush can clean the material adhering to the inner wall of the conveying pipe in time, avoiding material adhesion and blockage. In conjunction with the spiral pusher impeller, the anti-blocking ability of the conveying pipe and the stability of material conveying are further improved.

[0014] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0018] Please refer to the following: Figure 1-4The anti-clogging compound fertilizer granulator head structure includes a head body 1. One end of the head body 1 is connected to the conveying pipe 2 via a precision-machined through-hole interface. During manufacturing, the interface dimensions of the two are ensured to match precisely. High-precision machining ensures the flatness and concentricity of the interface, forming a continuous and smooth material conveying channel. During actual installation, an auxiliary positioning tool is used to align one end of the conveying pipe 2 with the interface of the head body 1 and then fix it in place. The mounting frame 3 is fixed to the surface of the head body 1 by welding or bolting. During installation, welding must ensure uniform and firm welds, and bolts must be of appropriate specifications and tightened with consistent torque to ensure the stability of the mounting frame 3. A support rod is vertically mounted on the mounting frame 3, and its top end is fixed to the surface of the gas storage tank 11 in the pulse air jet assembly 4 by welding or bolting. During installation, the verticality is accurately measured to ensure the gas storage tank 11 is horizontally stable and to avoid affecting the accuracy of gas injection. The output end of the gas storage tank 11 is threadedly connected to the jet pipe 10 via a sealed fitting, with a sealing ring to prevent gas leakage. One end of the jet pipe 10 is connected to the conveying pipe 2 by welding or flange connection. During welding, the process is strictly controlled to ensure strength and sealing. When connecting with a flange, ensure that the sealing gasket is installed correctly and tightened evenly. The angle between the jet pipe 10 and the conveying pipe 2 is 30 degrees, which is ensured by a special mold or positioning fixture. An electromagnetic pulse valve 9 is installed on the surface of the conveying pipe 2 via a threaded interface, and the interface is kept clean during connection. In this structure, the gas stored in the gas storage tank 11 is injected into the conveying pipe 2 at a 30-degree angle through the jet pipe 10 at a set frequency and pressure under the control of the electromagnetic pulse valve 9. The high-speed gas precisely impacts the material inside the conveying pipe 2 and near the discharge port of the machine head body 1, blowing away accumulated material and preventing blockage of the discharge port. Example

[0019] Please refer to the following: Figure 1-4The main shaft 5 installed inside the conveying pipe 2 is connected at one end to the granulator drive equipment via a coupling. The coupling is selected based on parameters such as shaft diameter and torque of both components, ensuring accurate alignment during installation for stable and efficient power transmission. A spiral impeller 6 is mounted on the circumference of the main shaft 5 via a key connection or interference fit. For key connections, the key is selected according to the keyway dimensions of the main shaft 5 and the impeller, ensuring a proper fit clearance. For interference fits, the interference amount is controlled. Assembly is achieved through heating or cooling to ensure reliable torque transmission between the impeller and the main shaft 5, enabling material pushing. Multiple mounting plates 7 are evenly distributed around the spiral impeller 6 on the circumference of the main shaft 5. The mounting plates 7 are fixed to the main shaft 5 by welding or bolting. During installation, accurate installation angles are ensured so that the wire brush 8 mounted on the top of each mounting plate 7 can effectively contact the inner wall of the conveying pipe 2. The wire brush 8 is fixed by bolts or clips, and the contact pressure with the inner wall is adjusted during installation. When the main shaft 5 rotates under the drive of the drive equipment, the spiral pusher impeller 6 rotates and pushes the material along the conveying pipe 2 axially toward the discharge hole of the machine head body 1. At the same time, the wire brush 8 rotates synchronously to scrape the inner wall of the conveying pipe 2, scraping off the adhering material and mixing it into the material flow. The two work together to prevent the material from stagnating and sticking, and improve the anti-blocking ability of the conveying pipe 2. Example

[0020] Please refer to the following: Figure 1-4 The machine head body 1 and the conveying pipe 2 are connected by a spiral connection. During manufacturing, a matching thread structure is machined at the connection point, and the thread specifications, pitch, and other parameters are strictly determined according to design requirements to ensure a tight and stable connection. During installation, sealant is first applied to the threaded area, and then the conveying pipe 2 is slowly screwed into the machine head body 1. The pipe is then gradually tightened to the specified torque to ensure no leakage. This connection method facilitates installation, and during equipment malfunction and maintenance, the conveying pipe 2 can be easily disassembled for inspection, repair, and replacement of internal parts. It also ensures a stable connection that can withstand the pressure and vibration during material conveying, preventing leakage. Example

[0021] Please refer to the following: Figure 1-4 The multiple mounting plates 7 are installed around the sides of the main shaft 5. During manufacturing, the number and distribution angle of the mounting plates 7 are precisely calculated based on the inner diameter of the conveying pipe 2 and the dimensions of the main shaft 5. During installation, specialized positioning tools and measuring instruments are used for calibration to ensure uniform distribution and accurate angles, guaranteeing that the wire brush 8 can fully cover the inner wall of the conveying pipe 2. Through this design, the wire brush 8 cleans the inner wall of the conveying pipe 2 without any blind spots when the main shaft 5 rotates, promptly removing adhering materials, further improving the anti-clogging effect, ensuring stable material conveying, and strengthening the anti-clogging performance of the conveying system. Example

[0022] Please refer to the following: Figure 1-4The top of the vertically mounted support rod on the mounting bracket 3 is fixed to the surface of the gas storage tank 11. The support rod material must have sufficient strength and rigidity to withstand the weight of the gas storage tank 11 and the working gas pressure. During installation, welding must ensure weld quality, and bolt connections must be tightened and anti-loosening measures must be taken to ensure the stable fixation of the gas storage tank 11. Only when the gas storage tank 11 is stable can the jet pipe 10 maintain the accurate installation position and angle, stably jetting gas into the conveying pipe 2 during operation, allowing the pulse air jet assembly 4 to continuously and effectively play its anti-clogging role, ensuring the accuracy and stability of gas jetting, and preventing material blockage in the conveying pipe 2. Example

[0023] Please refer to the following: Figure 1-4 The controller 12, adapted to the main body 1 of the granulator head, is connected to components such as the electromagnetic pulse valve 9 via cables. During connection, the wiring should be accurately followed according to the electrical wiring diagram, and proper protection and securing of the wiring should be ensured to avoid mechanical damage and electromagnetic interference. The controller 12 is typically installed on a control panel near the main body 1 for easy operation and monitoring. Through preset programs or operator commands, it controls the electromagnetic pulse valve 9, adjusting parameters such as the jet frequency and duration of the pulse air jet assembly 4 according to actual working needs. For example, if an increase in material conveying pressure or a decrease in speed is detected in the conveying pipe 2, the jet frequency is automatically increased or the jet time is extended to enhance the anti-clogging effect. Simultaneously, the working status of the granulator head is monitored in real time, such as the spindle speed 5 and the pressure in the air tank 11. Abnormalities are detected and alarms are triggered promptly, and protective measures are taken to achieve intelligent control and ensure the efficient and stable operation of the granulator head.

[0024] The working principle of the anti-clogging compound fertilizer granulator head structure provided by this utility model is as follows: When the granulator is started, the drive unit rotates the main shaft 5, and the spiral pusher impeller 6 installed on the side of the main shaft 5 rotates accordingly. At this time, the material enters the conveying pipe 2, and the spiral pusher impeller 6 uses its spiral blade structure to push the material along the axial direction of the conveying pipe 2 towards the discharge hole of the machine head body 1, providing a stable material conveying for the granulation process. During material conveying, some material may adhere to the inner wall of the conveying pipe 2. Over time, this adhered material can accumulate and cause blockages. The wire brush 8, rotating synchronously with the spiral impeller 6, has bristles that adhere closely to the inner wall of the conveying pipe 2, continuously scraping away the adhered material and allowing it to re-mix into the main material flow, continuing to be conveyed forward with the spiral impeller 6. Multiple mounting plates 7 and wire brushes 8 surrounding the main shaft 5 can thoroughly clean the inner wall of the conveying pipe 2, preventing blockages caused by material accumulation. Simultaneously, a certain amount of pressurized gas pre-stored in the gas storage tank 11 is injected into the conveying pipe 2 at a set frequency and duration through the jet pipe 10, which forms a 30-degree angle with the conveying pipe 2, under the control of the electromagnetic pulse valve 9. The high-speed inclined airflow precisely impacts the inside of the conveying pipe 2, especially creating a strong blowing force at the discharge port inside the die head body 1, promptly dispersing the material accumulated near the discharge port, preventing blockage caused by material accumulation and compaction, ensuring the unobstructed discharge port, and allowing the material to be smoothly discharged from the die head body 1 into the subsequent granulation process.

[0025] The spiral pusher impeller 6, wire brush 8 and pulse air jet assembly 4 work together to achieve multiple guarantees such as continuous material conveying, inner wall cleaning and anti-clogging of the discharge hole. Together they maintain a good material conveying environment in the conveying pipe 2, ensuring the efficient and stable operation of the compound fertilizer granulator head and continuously completing the granulation of compound fertilizer.
