Pneumatic conveying apparatus for powdery organic manure

Abstract

This invention relates to the field of pneumatic pipeline conveying technology and discloses a pneumatic conveying device for powdered organic fertilizer, including a cyclone dust collector and a fan. The cyclone dust collector and the fan are connected by a pipeline. A conveying pipe assembly is provided on one side of the cyclone dust collector. The conveying pipe assembly includes an elbow pipe, and straight feeding pipes are provided at both ends of the elbow pipe. By setting a plastic hose inside the elbow pipe, the fertilizer enters the plastic hose during conveying to achieve deflection. This avoids the fertilizer directly contacting the inner wall of the elbow pipe, which would easily cause the elbow pipe to wear faster. Secondly, to prevent fertilizer from adhering to the inner wall of the plastic hose during conveying, the air pressure inside the elbow pipe can be adjusted by driving the arc-shaped movable plate to raise and lower. By quickly controlling the deformation of the plastic hose, fertilizer particles that may be attached to the inner wall of the plastic hose can be effectively shaken off, effectively preventing material blockage and improving conveying quality.

Description

Technical Field

[0001] This invention relates to the field of pneumatic pipeline conveying technology, and in particular to a pneumatic conveying device for powdered organic fertilizer. Background Technology

[0002] Organic fertilizer is a fertilizer formed by the fermentation and decomposition of animal and plant residues, excrement and other organic matter. It is rich in organic matter and various nutrients, which can improve soil structure and promote crop growth. In the process of processing organic fertilizer powder, it needs to be transported between different processes. Pneumatic conveyor is a device for transporting organic fertilizer. Its main working principle is to use the energy of airflow to transport granular materials in a closed pipe along the airflow direction.

[0003] In pneumatic conveying, conveying pipelines need to be constructed according to different conveying scenarios. During the construction of the conveying pipeline, bends are required to achieve turning. When powdered organic fertilizer granules are conveyed, due to the thrust of the airflow, the powder particles will concentrate and exert a high-intensity continuous impact force on the outer wall of the bend pipe when flowing through the bend. This will result in greater wear at the bend section than in the straight section. At the same time, powdered organic fertilizer is prone to absorbing moisture and clumping. The airflow field in the bend area is turbulent, so the powder is prone to deposit and adhere to the inner side of the bend, thus forming local blockages, increasing resistance and reducing conveying efficiency. Traditional pneumatic conveying devices lack the function to deal with such wear and local adhesion at bends. Therefore, a pneumatic conveying device for powdered organic fertilizer is proposed to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a pneumatic conveying device for powdered organic fertilizer.

[0005] The pneumatic conveying device for powdered organic fertilizer provided by this invention adopts the following technical solution: A pneumatic conveying device for powdered organic fertilizer includes a cyclone dust collector and a blower, wherein the cyclone dust collector and the blower are connected by a pipeline, and a conveying pipe assembly is provided on one side of the cyclone dust collector. The conveying pipe assembly includes an elbow pipe, with feeding straight pipes at both ends of the elbow pipe. One of the feeding straight pipes is fixedly connected to the feeding direction of the cyclone dust collector. A plastic hose is provided inside the elbow pipe. Two auxiliary rings are integrally formed inside the elbow pipe. Rubber sealing rings are fixedly connected to both ends of the plastic hose. The auxiliary rings have annular grooves. The rubber sealing rings extend into the annular grooves and are adapted to the size of the annular grooves. A mounting base is fixedly connected to the outer bend of the elbow pipe. A housing is bolted to the top of the mounting base. An electric push rod is fixedly connected to the top of the housing. An arc-shaped movable plate is fixedly connected to one end of the electric push rod. The arc-shaped movable plate is slidably disposed inside the housing. The arc-shaped movable plate forms a sealing sliding fit with the inner walls of the housing and the base, respectively.

[0006] By adopting the above technical solution, a plastic hose is installed inside the elbow pipe. During fertilizer transportation, the fertilizer enters the plastic hose to achieve deflection. This avoids direct contact between the fertilizer and the inner wall of the elbow pipe, which would otherwise cause faster wear. Secondly, to prevent fertilizer from adhering to the inner wall of the plastic hose during transportation, the air pressure inside the elbow pipe can be adjusted by driving the arc-shaped movable plate to quickly control the deformation of the plastic hose and effectively shake off any fertilizer particles that may be attached to the inner wall of the plastic hose, effectively preventing material blockage and improving the quality of transportation. Finally, after the housing is removed, operators can inspect and maintain the inside of the elbow pipe through the opening at the base location. Maintenance work can be carried out without stopping the machine, even without removing the plastic hose, ensuring transportation efficiency and safety during use.

[0007] Preferably, the elbow pipe has two fixing rings connected internally by threads. The two fixing rings are respectively set on one side of the two auxiliary rings. The fixing rings are rotatably connected to the fixing rings, and the two fitting rings are respectively fitted to the two rubber sealing rings.

[0008] By adopting the above technical solution, a sealing fit is formed between the rubber sealing ring and the auxiliary ring.

[0009] Preferably, the top of the box is provided with multiple exhaust holes, and when the arc-shaped movable plate moves up and down, the gas inside the box is discharged through the exhaust holes.

[0010] By adopting the above technical solution, the opening of the exhaust port can ensure that the arc-shaped movable plate can move flexibly inside the box.

[0011] Preferably, a first flange is fixedly connected to one end of each of the two feeding straight pipes facing the elbow pipe, a second flange is provided at the end of the elbow pipe facing the cyclone dust collector, and a third flange is fixedly connected to the other end of the elbow pipe. The two first flanges are respectively connected to the second flange and the third flange by bolts.

[0012] By adopting the above technical solution, a detachable fixed connection is formed through bolt connection.

[0013] Preferably, the end of the elbow facing the second flange is connected to a first connecting pipe via a sealed bearing, and a second connecting pipe is fixedly connected to the second flange. The first connecting pipe extends into the interior of the second connecting pipe and is threadedly connected to the second connecting pipe. A fixing bracket is fixedly connected to the elbow, and multiple positioning rods are fixedly connected to one side of the second flange.

[0014] By adopting the above technical solution, after the first connecting pipe and the second connecting pipe are connected and installed, the assembly of the second flange and the elbow pipe is completed.

[0015] Preferably, all of the positioning rods pass through the fixing frame, and a fastening ring is threadedly connected to the outside of each positioning rod, with the fastening ring fitting against one side of the fixing frame.

[0016] By adopting the above technical solution, after the positioning rod passes through the fixed frame, the positioning ring is fixed on the fixed frame by the fastening ring.

[0017] Preferably, the fixing frame includes an inner combination ring and an outer combination ring, the inner combination ring being fixedly connected to the outside of the elbow pipe, and the outer combination ring being disposed outside the inner combination ring.

[0018] By adopting the above technical solution, the annular channel formed between the inner and outer combined rings can be used for the insertion of positioning rods.

[0019] Preferably, the inner combined ring is provided with multiple connecting rods on the side opposite to the positioning rod, and the two ends of the multiple connecting rods are fixedly connected to the inner combined ring and the outer combined ring respectively.

[0020] By adopting the above technical solution, the connecting rod fixes the inner and outer composite rings together, ensuring their stability.

[0021] Preferably, the elbow pipe has a movable ring connected to the outside of the end facing the third flange via a thread, and the elbow pipe has multiple inspection ports, all of which are located inside the movable ring.

[0022] By adopting the above technical solution, the inspector can observe the internal condition of the elbow pipe.

[0023] Preferably, a guide plate is fixedly connected to the top of the arc-shaped movable plate, and the guide plate penetrates the top wall of the box.

[0024] By adopting the above technical solution, the guide plate ensures that the curved movable plate can move smoothly.

[0025] In summary, the present invention has the following beneficial technical effects: 1. A pneumatic conveying device for powdered organic fertilizer, which uses a plastic hose installed inside the elbow pipe to allow fertilizer to enter and change direction during conveying. This avoids direct contact between the fertilizer and the inner wall of the elbow pipe, which would otherwise cause faster wear. Secondly, to prevent fertilizer from adhering to the inner wall of the plastic hose during conveying, the air pressure inside the elbow pipe can be adjusted by driving the arc-shaped movable plate to quickly control the deformation of the plastic hose and effectively shake off any fertilizer particles that may be attached to the inner wall of the plastic hose, thus preventing material blockage and improving conveying quality. Finally, after removing the housing, operators can inspect and maintain the inside of the elbow pipe through the opening at the base location. This allows for maintenance work to be carried out without removing the plastic hose, ensuring conveying efficiency and safety during use.

[0026] 2. A pneumatic conveying device for powdered organic fertilizer, wherein the plastic hose can be easily disassembled and assembled on the elbow pipe for easy replacement and maintenance. After the plastic hose is removed, the movement of the arc-shaped lifting plate can be controlled so that its inner curved surface connects with the inner curved surface of the elbow pipe to form a complete bending surface that can guide the conveyed fertilizer. This ensures that the pneumatic conveying of fertilizer can still be carried out normally after the plastic hose is removed, thus enhancing its functionality.

[0027] 3. A pneumatic conveying device for powdered organic fertilizer, which can directly control the elbow pipe to rotate flexibly on the first connecting pipe in response to different conveying needs during the initial pipeline construction or subsequent pneumatic conveying process, thereby realizing the function of flexibly adjusting the conveying direction during construction and subsequent conveying to adapt to different conveying scenarios. Compared with the traditional operation of dismantling, adjusting the direction and reassembling after installation, it is more convenient and flexible.

[0028] 4. A pneumatic conveying device for powdered organic fertilizer, wherein after the control ring moves above the inspection port, the operator can directly observe whether there are leaking fertilizer particles inside the elbow pipe through the inspection port, or during the conveying process, the inspection port can be directly exposed. When the plastic hose is damaged, the gas during the conveying process will also be blown out of the inspection port. The operator can judge the integrity of the plastic hose by whether there is gas flowing out of the inspection port, thereby ensuring the safety and stability of the fertilizer conveying process.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 The present invention will be described in further detail below.

[0032] like Figures 1 to 6 As shown, a pneumatic conveying device for powdered organic fertilizer according to an embodiment of the present invention includes a cyclone dust collector 1 and a blower 2. The cyclone dust collector 1 and the blower 2 are connected by a pipe, and a conveying pipe assembly 3 is provided on one side of the cyclone dust collector 1. The conveying pipe assembly 3 includes an elbow pipe 31, with feeding straight pipes 32 at both ends of the elbow pipe 31. One of the feeding straight pipes 32 is fixedly connected to the feeding direction of the cyclone dust collector 1. A plastic hose 33 is provided inside the elbow pipe 31. Two auxiliary rings 34 are integrally formed inside the elbow pipe 31. Rubber sealing rings 35 are fixedly connected to both ends of the plastic hose 33. An annular groove is provided on the auxiliary ring 34. The rubber sealing ring 35 extends into the annular groove and is adapted to the size of the annular groove. A mounting base 36 is fixedly connected to the outer bend of the elbow pipe 31. A housing 37 is bolted to the top of the mounting base 36. An electric push rod 38 is fixedly connected to the top of the housing 37. An arc-shaped movable plate 39 is fixedly connected to one end of the electric push rod 38. The arc-shaped movable plate 39 is slidably disposed inside the housing 37. The arc-shaped movable plate 39 forms a sealing sliding fit with the inner wall of the housing 37 and the base, respectively.

[0033] In this device, the cyclone dust collector 1 is an existing gas and particle separation device, so it will not be described further here. In the specific implementation process, the fan 2 generates suction, and the powdered organic fertilizer particles are drawn into the cyclone dust collector 1 through the conveying pipe assembly 3. The cyclone dust collector 1 removes the powdered organic fertilizer from the gas, thus realizing the pipeline conveying function of the powdered organic fertilizer. During the fertilizer conveying process in the conveying pipe assembly 3, a plastic hose 33 is installed inside the elbow pipe 31. The fertilizer enters the plastic hose 33 during conveying to achieve deflection, thus avoiding direct contact between the fertilizer and the inner wall of the elbow pipe 31, which could easily cause faster wear on the elbow pipe 31. The plastic hose 33 is made of materials such as polyurethane or thermoplastic polyurethane to ensure its performance during use. To enhance wear resistance and elasticity, and to prevent fertilizer particles from impacting the inner wall of the plastic hose 33 during the turning process and causing adhesion, the electric push rod 38 can drive the arc-shaped movable plate 39 to rise and fall. When the arc-shaped movable plate 39 descends, the gas inside the housing 37 enters the elbow pipe 31, causing the air pressure inside the elbow pipe 31 to increase, thereby squeezing the plastic hose 33 inside the elbow pipe 31 and causing the plastic hose 33 to deform. Then, the arc-shaped movable plate 39 is driven to move upward, the air pressure inside the pipe decreases and resets, causing the plastic hose 33 to return to its initial shape. In this way, by quickly controlling the deformation of the plastic hose 33, fertilizer particles that may be attached to the inner wall of the plastic hose 33 can be effectively shaken off, effectively avoiding material blockage and improving the conveying quality. Secondly, the plastic hose 33 can be removed from the elbow pipe 31. If the plastic hose 33 needs to be disassembled, replaced, or maintained due to wear or other special circumstances, and a new plastic hose 33 cannot be found in time to replace it, the arc-shaped movable plate 39 can be directly driven to move even without the plastic hose 33. This moves the inner curved surface of the arc-shaped movable plate 39 to the corresponding height of the inner curved surface of the elbow pipe 31, thus connecting the inner curved surface of the arc plate with the inner curved surface of the elbow pipe 31 to form a complete bending surface that can guide the conveyed fertilizer. This ensures the normal operation of the pneumatic conveying of fertilizer and improves the flexibility of use. At the same time, after the bolts between the contact box 37 and the mounting base 36 are fixed, the box 37 can be removed. At this time, the operator can inspect and maintain the inside of the elbow pipe 31 through the opening at the base location. Maintenance work can be carried out without stopping the machine without removing the plastic hose 33, thus improving the conveying efficiency.

[0034] The elbow pipe 31 has two fixing rings 391 connected by threads inside. The two fixing rings 391 are respectively set on one side of the two auxiliary rings 34. The fixing rings 391 are rotatably connected to the fixing rings 391, and the two fitting rings 392 are respectively fitted to the two rubber sealing rings 35. The rubber sealing ring 35 can elastically deform. During installation, the rubber sealing ring 35 and the plastic hose 33 are directly pushed into one end of the elbow pipe 31. During the pushing process, the opening of the mounting seat 36 on the 31 can be used for auxiliary pulling to ensure smooth insertion. After insertion, the protruding parts of the rubber sealing ring 35 at both ends of the plastic hose 33 are inserted into the grooves on the auxiliary ring 34 to ensure a seal between the rubber sealing ring 35 and the auxiliary ring 34. After insertion, the fixing ring 391 is screwed into the opening of the elbow pipe 31, causing the fixing ring 391 to tightly press the rubber sealing ring 35 onto the auxiliary ring 34, thus completing the fixed installation of the plastic hose 33. Similarly, after removing the fixing ring 391, the plastic hose 33 can be quickly removed for convenient installation and removal, making it more convenient to use.

[0035] The top of the box 37 is provided with multiple exhaust holes 393. When the arc-shaped movable plate 39 moves up and down, the gas inside the box 37 is discharged through the exhaust holes 393. When the curved movable plate 39 moves, it compresses the gas inside the box 37. The compressed gas can be discharged through the exhaust port 393, thereby ensuring that the curved movable plate 39 moves smoothly.

[0036] Two straight feed pipes 32 are fixedly connected to a first flange 394 at one end facing the elbow pipe 31, a second flange 395 is provided at one end of the elbow pipe 31 facing the cyclone dust collector 1, and a third flange 396 is fixedly connected to the other end of the elbow pipe 31. The two first flanges 394 are respectively connected to the second flange 395 and the third flange 396 by bolts. The advantage of bolted connections is that the installation and disassembly of the two first flanges 394, the second flange 395, and the third flange 396 can be completed quickly, facilitating assembly.

[0037] The elbow pipe 31 is connected to the first connecting pipe 397 via a sealed bearing at one end facing the second flange 395. The second connecting pipe 398 is fixedly connected to the second flange 395. The first connecting pipe 397 extends into the second connecting pipe 398 and is connected to the second connecting pipe 398 via a thread. A fixing bracket 4 is fixedly connected to the elbow pipe 31. Multiple positioning rods 381 are fixedly connected to one side of the second flange 395. After the first connecting pipe 397 is rotated and screwed into the second connecting pipe 398, the assembly between the elbow pipe 31 and the second flange 395 can be completed. The advantage of this assembly method is that during the erection of the conveying pipe assembly 3, the elbow pipe 31 can be flexibly rotated on the first connecting pipe 397 according to the turning requirements of different directions. This enables flexible adjustment of the conveying direction during the erection and subsequent conveying process to adapt to different conveying scenarios.

[0038] Multiple positioning rods 381 pass through the fixing frame 4, and a fastening ring 399 is threadedly connected to the outside of the positioning rod 381. The fastening ring 399 fits against one side of the fixing frame 4. When the elbow pipe 31 is turned, the fixing bracket 4 rotates on the outside of the elbow pipe 31. After the rotation is completed, the fixing ring 399 is tightened directly on the outside of the fastening ring 399 to fix the fixing bracket 4 to the outside of the positioning rod 381, so as to ensure the stability of the elbow pipe 31 after the turn adjustment.

[0039] The fixing frame 4 includes an inner combination ring 41 and an outer combination ring 42. The inner combination ring 41 is fixedly connected to the outside of the elbow pipe 31, and the outer combination ring 42 is disposed outside the inner combination ring 41. By establishing the inner combination ring 41 and the outer combination ring 42, an annular groove is reserved between them so that the positioning rod 381 can pass through.

[0040] Multiple connecting rods 43 are provided on the side of the inner combined ring 41 away from the positioning rod 381, and the two ends of the multiple connecting rods 43 are fixedly connected to the inner combined ring 41 and the outer combined ring 42 respectively. The inner combination ring 41 and the outer combination ring 42 are fixedly connected by a connecting rod 43. The connecting rod 43 is located on the side opposite to the positioning rod 381 to avoid the connecting rod 43 obstructing the positioning rod 381 when the fixed ring 391 rotates.

[0041] The elbow pipe 31 is connected to the outside of the third flange 396 by a moving ring 5 through a thread. Multiple inspection ports 6 are opened on the elbow pipe 31, and the multiple inspection ports 6 are all located inside the moving ring 5. After rotating the moving ring 5, it can be adjusted up and down outside the elbow pipe 31. When the moving ring 5 stops outside the inspection port 6, the inspection port 6 is sealed to ensure the airtightness of the elbow pipe 31. If the plastic hose 33 is damaged and leaks, fertilizer particles may fall between the elbow pipe 31 and the plastic hose 33. In this case, after controlling the moving ring 5 to move above the inspection port 6, the operator can directly observe whether there are leaked fertilizer particles inside the elbow pipe 31 through the inspection port 6. Alternatively, during the conveying process, the inspection port 6 can be directly exposed. When the plastic hose 33 is damaged, the gas during the conveying process will also blow out of the inspection port 6. The operator can judge the integrity of the plastic hose 33 by whether there is gas flowing out of the inspection port 6, thereby ensuring the safety and stability of the fertilizer conveying process.

[0042] A guide plate is fixedly connected to the top of the arc-shaped movable plate 39, and the guide plate penetrates the top wall of the box 37. The guide plate guides the curved movable plate 39, enabling it to move smoothly.

[0043] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
