Description

Technical Field

[0001] This invention belongs to the field of fertilizer production technology, specifically a feeding system for filling bags of potassium magnesium sulfate fertilizer to prevent material adhesion. Background Technology

[0002] Potassium magnesium sulfate fertilizer is a very important fertilizer. It not only provides plants with magnesium and sulfur elements, but also loosens the soil, promotes the growth and development of plant leaves, branches and roots, and makes the plant roots large. At the same time, it can help plants absorb nitrogen, phosphorus and other elements in the soil more quickly, and increase the plant's ability to resist diseases.

[0003] In the production of potassium magnesium sulfate fertilizer, which includes ammonium sulfate and other components, ammonium sulfate is highly hygroscopic. When the fertilizer is exposed to air, ammonium sulfate easily absorbs moisture from the air, causing the fertilizer granules to become wet and potentially leading to granule adhesion. Simultaneously, the fertilizer granules may generate static electricity due to friction and collision, which can cause the granules to attract each other, further increasing the likelihood of adhesion. Additionally, clumping caused by external pressure during the filling process can also hinder production. Therefore, anti-adhesion treatment is necessary. Summary of the Invention

[0004] The purpose of this invention is to provide a feeding system for filling potassium magnesium sulfate fertilizer bags that prevents material adhesion, facilitating the separation and processing of materials of different sizes during the filling process and reducing the possibility of material adhesion.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A feeding system for filling potassium magnesium sulfate fertilizer bags to prevent material adhesion includes a cooling and separation mechanism and a controller;

[0007] The cooling separation mechanism includes a housing, a first fan and a second fan. The first fan and the second fan rotate in opposite directions. The housing has an inlet and an outlet arranged from top to bottom. The first fan is located in the inlet and the second fan is located in the outlet. The inlet and the outlet are not on the same horizontal line.

[0008] The controller is used to input timing control instructions, which include start-up instructions and stop instructions for the first fan or the second fan at different time periods, as well as speed adjustment instructions for the first fan or the second fan. The controller also sends the timing control instructions corresponding to the current time to the first fan or the second fan. The first fan or the second fan is used to generate different air force differences to separate materials of different particle sizes.

[0009] The above scheme achieves the following beneficial effects: the turbulent air generated by the first and second fans helps to agitate and disperse different materials, thereby cooling the materials and preventing them from sticking together.

[0010] Meanwhile, by controlling the generated wind force difference, materials of different sizes are separated into different layers during the falling process. Compared with existing technologies, this method ensures the uniformity of the collected materials while reducing adhesion during the filling process, thereby improving product quality.

[0011] Furthermore, the timing control commands include overweight commands, balance commands, and weightlessness commands;

[0012] Under the overload command, the controller sends a first interval start command to both the first fan and the second fan. Based on the speed adjustment command, the first fan's speed is made to be greater than the second fan's speed. The first fan and the second fan stop working after the time of the first interval start command ends.

[0013] Under the balance command, the controller sends start commands to the first fan and the second fan. Based on the speed adjustment command, the speed of the second fan is made to be greater than that of the first fan, and the material is in a brief suspended state based on the speed difference between the first fan and the second fan.

[0014] Under weightlessness command, the controller sends a shutdown command to the first fan and a second interval start command to the second fan. The second fan operates based on the continuous working time specified in the second interval start command.

[0015] Beneficial effects: Under the overweight command, large particles are separated from small particles due to displacement caused by inertial forces. Under the balance command, the resulting speed difference generates rotational shear force, separating pre-adhesive or potentially agglomerated particles to facilitate subsequent packaging. Under the weightlessness command, the reverse force generated by the second fan further stratifies particles of different sizes, reducing the possibility of material agglomeration.

[0016] Furthermore, the blades of the second blower are stepped, and several air outlets are opened on the blades; the discharge outlets are arranged in a ring around the second blower.

[0017] Beneficial effects: The material is separated by contact between the top of the fan blades and the material, reducing the mixing of falling materials. At the same time, the oblique wind generated by the air outlet separates the material, reducing the material's prolonged contact with the fan and thus reducing adhesion. Meanwhile, the wind force drives the fan blades to rotate, accelerating the rotation of the fan blades.

[0018] Furthermore, a funnel-shaped feed pipe is fixedly connected to the top of the box, and a mounting bracket is fixedly connected to the center of the feed pipe. The first fan is fixedly connected to the mounting bracket, and the feed inlet is located between the feed pipe and the mounting bracket.

[0019] Beneficial effects: The funnel-shaped feed pipe facilitates the entry and guidance of materials and provides support space for the installation of the first blower.

[0020] Furthermore, a conical guide block is fixedly connected between the first fan and the mounting frame, with the diameter of the end of the guide block near the mounting frame being smaller than the diameter of the end of the guide block near the first fan.

[0021] Beneficial effect: The conical guide block forms an arc surface to reduce the support for the material, so that the material falling onto the guide block can fall off easily.

[0022] Furthermore, a filter screen is also installed at the discharge port.

[0023] Beneficial effects: The material is filtered through a filter screen to separate large clumps, which facilitates the subsequent recycling of the collected large clumps and ensures the uniformity of fertilizer particles in the subsequent packaging.

[0024] Furthermore, a shaking mechanism is provided at the top of the filter screen. The shaking mechanism includes an adjusting shaft, which is fixedly connected to the top of the filter screen and slides with the housing. A spring is also fixedly connected to the adjusting shaft and the housing.

[0025] Beneficial effects: The spring's swaying motion causes the filter screen to shake, facilitating the separation of materials from the filter screen.

[0026] Furthermore, a pressure plate is hinged to the end of the adjusting shaft away from the filter screen, and a rotating shaft is hinged to the center of the pressure plate. The rotating shaft rotates in conjunction with the housing. When the adjusting shaft moves to the lowest point, the pressure plate and the bottom of the fan blade are horizontal to each other.

[0027] Beneficial effects: The adjusting shaft drives the extension of the pressure plate to receive materials, and the rotation of the fan blades crushes and separates the materials on the pressure plate, reducing the formation of lumps. At the same time, the arc surface formed by the rotation of the pressure plate pushes and separates the gaps between the fan blades.

[0028] Furthermore, several striking mechanisms are arranged around the feed pipe in a circumferential direction. Each striking mechanism includes a sealing chamber, in which a first piston is slidably fitted. A connecting pipe and a sleeve are provided between the first piston and the bottom of the sealing chamber, and the connecting pipe and the sleeve are respectively connected to the sealing chamber.

[0029] A one-way valve is also connected inside the connecting pipe. The end of the connecting pipe away from the sealing chamber is connected to the feed pipe. One end of the sleeve is connected to the sealing chamber, and the other end of the sleeve is connected to the inside of the box. A second piston is slidably fitted inside the sleeve. A knocking rod is fixedly connected to the end of the second piston away from the sealing chamber. A return spring is sleeved on the knocking rod. The return spring is located between the second piston and the sleeve.

[0030] Below the striking rod is an L-shaped locking rod. Both the locking rod and the striking rod have mating grooves for limiting the striking rod. The end of the locking rod away from the striking rod is located below the sealing chamber. The sleeve and the sealing chamber have pressure relief ports located at the bottom of the sealing chamber.

[0031] A central rod is fixedly connected to the center of the bottom of the first piston. Several arc-shaped pieces are hinged on the central rod. The arc-shaped pieces are located at the end of the central rod away from the piston, and the arc-shaped pieces are arranged in a ring around the central rod.

[0032] When the curved plate is in its normal state, it remains perpendicular to the ground; when the curved plate is in its open state, it remains horizontal to the ground.

[0033] When the first piston moves to the point furthest from the bottom of the sealing chamber, the locking rod separates from the striking rod, the striking rod contacts the feed pipe, and the pressure relief port contacts the second piston; when the first piston moves to the point closest to the bottom of the sealing chamber, the locking rod and the striking rod engage through the mating groove, the striking rod separates from the feed pipe, and the pressure relief port separates from the second piston.

[0034] Beneficial effects: By restricting the flow of air from the feed pipe into the sealed chamber through the one-way valve, the turbulent airflow inside the chamber pushes the arc-shaped plate to open, thereby continuously increasing the pressure inside the sealed chamber and causing the center rod to move upward, while the return spring remains in its normal state.

[0035] When the open arc-shaped plate on the locking rod contacts the locking rod, it causes the mating grooves of the locking rod and the striking rod to misalign, releasing the huge pressure in the sealing chamber to push the second piston to move. When the second piston passes the pressure relief port, the interior of the sealing chamber connects with the interior of the housing and is reset.

[0036] Furthermore, the curved pieces are petal-shaped or arc-shaped.

[0037] Beneficial effect: The shape of the arc-shaped plate forms a concave surface, which facilitates the residual propulsion of the turbulent airflow to a horizontal position, thereby assisting in the movement of the first piston. Attached Figure Description

[0048] The following detailed description illustrates the specific implementation method:

[0049] The reference numerals in the accompanying drawings include: housing 1, mounting bracket 11, feed pipe 12, discharge port 13, first fan 2, guide block 21, second fan 3, fan blade 31, filter screen 4, adjusting shaft 41, spring 42, pressure plate 43, vibration chamber 5, first piston 51, arc plate 52, locking rod 53, second piston 54, striking rod 55, mating groove 56, connecting pipe 6.

[0050] Example 1

[0051] The basic implementation examples are as follows: Figures 1 to 10 As shown: A feeding system for filling potassium magnesium sulfate fertilizer bags to prevent material adhesion, including a cooling and separation mechanism and a controller.

[0052] The cooling separation mechanism includes a housing 1, a first fan 2, and a second fan 3. The first fan 2 and the second fan 3 rotate in opposite directions. The housing 1 has an inlet and an outlet 13 arranged sequentially from top to bottom. The first fan 2 is located inside the inlet, and the second fan 3 is located inside the outlet 13. The inlet and outlet 13 are not on the same horizontal line. A funnel-shaped inlet pipe 12 is welded to the top of the housing 1. A mounting bracket 11 is welded to the center of the inlet pipe 12. The first fan 2 is bolted to the mounting bracket 11. The inlet is located between the inlet pipe 12 and the mounting bracket 11. A conical guide block 21 is welded between the first fan 2 and the mounting bracket 11. The diameter of the end of the guide block 21 closest to the mounting bracket 11 is smaller than the diameter of the end of the guide block 21 closest to the first fan 2. The fan blades 31 of the second fan 3 are stepped, and several air outlets are opened on the fan blades 31. The outlet 13 is arranged in a ring around the second fan 3.

[0053] A filter screen 4 is also provided inside the discharge port 13. The filter screen 4 is slidably engaged with the housing 1. A shaking mechanism is also provided on the top of the filter screen 4. The shaking mechanism includes an adjusting shaft 41, which is welded to the top of the filter screen 4 and is slidably engaged with the housing 1. A spring 42 is provided between the adjusting shaft 41 and the housing 1. One end of the spring 42 is welded to the housing 1, and the other end of the spring 42 is welded to the adjusting shaft 41. A pressure plate 43 is hinged to the end of the adjusting shaft 41 away from the filter screen 4. A rotating shaft is hinged to the center of the pressure plate 43. The rotating shaft is rotatably engaged with the housing 1. When the adjusting shaft 41 moves to the lowest point, the pressure plate 43 and the bottom of the fan blade 31 are horizontal to each other.

[0054] The controller is used to input timing control instructions, which include start-up instructions and stop instructions for the first fan 2 or the second fan 3 at different time periods, and speed adjustment instructions corresponding to the first fan 2 or the second fan 3. The controller also sends the timing control instructions corresponding to the current time to the first fan 2 or the second fan 3. The first fan 2 or the second fan 3 is used to generate different air force differences to separate materials of different particle sizes.

[0055] The timing control commands include overload commands, balance commands, and weightlessness commands. Under the overload command, the controller sends a first interval start command to both the first fan 2 and the second fan 3. Based on the speed adjustment command, the speed of the first fan 2 is made greater than that of the second fan 3. The first fan 2 and the second fan 3 stop working after the time of the first interval start command ends. Under the balance command, the controller sends a start command to both the first fan 2 and the second fan 3. Based on the speed adjustment command, the speed of the second fan 3 is made greater than that of the first fan 2, and the material is in a brief suspended state based on the speed difference between the first fan 2 and the second fan 3. Under the weightlessness command, the controller sends a shut-off command to the first fan 2 and simultaneously sends a second interval start command to the second fan 3. The second fan 3 works based on the continuous working time in the second interval start command.

[0056] For example, under the overweight command, during the material falling process, the rotation speed of the first fan 2 is changed to make the material fall at the same speed, forming the same magnitude of acceleration; after the first fan 2 and the second fan 3 stop, because the materials are produced in the same batch, the components of different sizes tend to be consistent, and the large particles and small particles are separated due to displacement changes caused by inertial forces.

[0057] Under the balancing command, the resulting speed difference causes pre-adhesive or potentially agglomerated material particles to be temporarily retained. Meanwhile, the wind directions generated by the first fan 2 and the second fan 3 disturb each other, creating a rotational shear force that causes the material particles to rotate. This rotational shear force separates the pre-adhesive or potentially agglomerated material particles, facilitating subsequent bagging.

[0058] Under the weightlessness command, the reverse force generated by the second fan 3 changes the motion state of particles of different volumes. Under the same force, smaller and lighter particles are more likely to be displaced, thereby causing particles of different sizes to be stratified again, reducing the possibility of material adhesion.

[0059] The specific implementation process is as follows: materials are added manually and enter the box 1 through the feed pipe 12. The rotation of the first fan 2 accelerates the intake and dispersion of materials. The turbulent air generated by the first fan 2 and the second fan 3 is used to stir and disperse different materials so that the materials can be cooled and are less likely to stick together.

[0060] During the material falling process, the first fan 2 or the second fan 3 rotates based on overweight command, balance command and weightlessness command. The resulting air force difference allows materials of different sizes to be separated into different layers during the falling process, so as to ensure the uniformity of the collected materials and reduce the occurrence of adhesion during the filling process.

[0061] During the process of falling material coming into contact with the fan blade 31, the material is separated by contact between the top of the fan blade 31 and the material to reduce the mixing of falling material. At the same time, the oblique wind generated by the air outlet separates the material to reduce the material's long-term contact with the fan and reduce the occurrence of adhesion. Meanwhile, the wind force drives the fan blade 31 to rotate, thereby accelerating the rotation of the fan blade 31.

[0062] When the falling material comes into contact with the filter screen 4, the increased weight causes the filter screen 4 to move downwards, which in turn causes the spring 42 to shake, thus shaking the filter screen 4 and facilitating the separation of material and large clumps from it. Simultaneously, the adjusting shaft 41 drives the extension of the pressure plate 43 to receive the material. The rotation of the fan blades 31 then crushes and separates the material on the pressure plate 43, reducing the formation of clumps and ensuring the uniformity of the material.

[0063] Example 2

[0064] The difference from the above embodiment is that a number of striking mechanisms are arranged around the feed pipe 12 in a circumferential direction. The striking mechanism includes a sealing chamber, in which a first piston 51 is slidably fitted. A connecting pipe 6 and a sleeve are provided between the first piston 51 and the bottom of the sealing chamber. The connecting pipe 6 and the sleeve are respectively connected to the sealing chamber.

[0065] A one-way valve is also connected inside the connecting pipe 6. The end of the connecting pipe 6 away from the sealing chamber is connected to the feed pipe 12. One end of the sleeve is connected to the sealing chamber, and the other end of the sleeve is connected to the inside of the housing 1. A second piston 54 is slidably fitted inside the sleeve. A striking rod 55 is fixedly connected to the end of the second piston 54 away from the sealing chamber. A return spring 42 is fitted on the striking rod 55 and is located between the second piston 54 and the sleeve. An L-shaped locking rod 53 is provided below the striking rod 55. Both the locking rod 53 and the striking rod 55 are provided with mating grooves 56 for limiting the striking rod 55. The end of the locking rod 53 away from the striking rod 55 is located below the sealing chamber. The sleeve and the sealing chamber have pressure relief ports located at the bottom of the sealing chamber. A central rod is welded to the center of the bottom of the first piston 51. Several arc-shaped pieces 52 are hinged to the central rod. The arc-shaped pieces 52 are petal-shaped or arc-shaped. The arc-shaped pieces 52 are located at the end of the central rod away from the piston, and the arc-shaped pieces 52 are arranged in a ring around the central rod.

[0066] When the arc-shaped plate 52 is in its normal state, it remains perpendicular to the ground. When the arc-shaped plate 52 is in its open state, it remains horizontal to the ground. When the first piston 51 moves to the point furthest from the bottom of the sealing chamber, the locking rod 53 separates from the striking rod 55, the striking rod 55 contacts the feed pipe 12, and the pressure relief port contacts the second piston 54. When the first piston 51 moves to the point closest to the bottom of the sealing chamber, the locking rod 53 and the striking rod 55 engage through the mating groove 56, the striking rod 55 separates from the feed pipe 12, and the pressure relief port separates from the second piston 54.

[0067] The specific implementation process is as follows: By restricting the one-way valve, the air from the feed pipe 12 continuously enters the sealed chamber. At the same time, the turbulent air inside the housing 1 pushes the arc-shaped plate 52 to open, thereby increasing the area of ​​the first piston 51 under the turbulent airflow through the central rod, which in turn assists in moving the first piston 51. At this time, the locking rod 53 restricts the movement of the second piston 54 and the striking rod 55 by the restriction of the mating groove 56. The second piston 54 is not connected to the pressure relief port, so that the pressure inside the sealed chamber continues to increase, causing the central rod to move upward, and the return spring 42 is in the normal state.

[0068] When the arc-shaped piece 52 on the locking rod 53 contacts the locking rod 53, the mating groove 56 of the locking rod 53 and the striking rod 55 is misaligned, and the huge pressure in the sealing chamber is released to push the second piston 54 to move. This pushes the striking rod 55 on the second piston 54 to contact the feed pipe 12, shaking off any material that may accumulate on the feed pipe 12 and reducing material adhesion. At this time, the return spring 42 is compressed. When the second piston 54 passes through the pressure relief port, the inside of the sealing chamber is connected to the inside of the housing 1 to restore the air pressure balance. The weight of the first piston 51 is used to reset the piston, and the compressed return spring 42 pushes the second piston 54 to reset.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention.
