Description

Technical Field

[0001] This utility model relates to the field of fertilizer production equipment, and in particular to a feeding structure for a polyglutamic acid fertilizer production device. Background Technology

[0002] Polyglutamic acid fertilizer is an organic fertilizer made primarily from grain processing by-products. During its production, various raw materials need to be fed into a mixing device in specific proportions. Existing feeding structures typically only achieve simple conveying functions, but the following problems easily arise during material conveying: 1. Impurities or large particles may be mixed into the raw materials, affecting the quality of subsequent processing; 2. The feed rate is difficult to control precisely, leading to inaccurate raw material ratios; 3. Abnormal raw material moisture content cannot be detected in time, affecting product quality; 4. Blockages are prone to occur during the feeding process, affecting production efficiency.

[0003] Therefore, a feeding structure for a polyglutamic acid fertilizer production device is proposed to solve the above problems. Utility Model Content

[0004] This invention overcomes the shortcomings of the prior art and provides a feeding structure for a polyglutamic acid fertilizer production device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a feeding structure for a polyglutamic acid fertilizer production device, comprising: a feeding hopper, a conveying pipe and a driving assembly, wherein the bottom of the feeding hopper is connected to the conveying pipe through a connecting flange, and a spiral conveying shaft is provided inside the conveying pipe, the spiral conveying shaft being driven to rotate by the driving assembly;

[0006] The top of the feed hopper is provided with a detachable filter cover, on which filter holes are evenly distributed. A humidity sensor is provided on the inner wall of the feed hopper, and the detection end of the humidity sensor extends into the interior of the feed hopper. A flow sensor mounting bracket is provided at the middle position of the outer side of the conveying pipe. The flow sensor is fixed by the bracket and its detection end penetrates the pipe wall and extends into the conveying pipe.

[0007] The drive assembly is electrically connected to the controller. The humidity sensor and the flow sensor are both electrically connected to the controller via signal cables. The controller receives electrical signals from the humidity sensor and the flow sensor, thereby driving the drive assembly to work.

[0008] In a preferred embodiment of this utility model, the filter cover is provided with a magnetic adsorption strip on its edge, and a magnetic groove is provided at the corresponding position on the top of the feed hopper. The filter cover is detachably connected to the feed hopper through the magnetic adsorption strip.

[0009] In a preferred embodiment of the present invention, the inner wall of the feed hopper is provided with an inclined guide plate, and 3-6 guide plates are evenly distributed along the circumference of the inner wall of the feed hopper.

[0010] In a preferred embodiment of this utility model, the conveying pipe is provided with an observation window, which is made of a transparent and wear-resistant material.

[0011] In a preferred embodiment of this invention, the blade spacing of the spiral conveyor shaft gradually decreases from the feed end to the discharge end.

[0012] In a preferred embodiment of this utility model, a vibration motor is provided on the outside of the feed hopper, and the vibration motor is electrically connected to the controller.

[0013] In a preferred embodiment of this utility model, the controller is connected to an alarm device. When the humidity sensor detects a value exceeding a preset range or the flow sensor detects an abnormal value, the alarm device issues an alarm.

[0014] In a preferred embodiment of this invention, a pressure sensor is provided at the end of the delivery pipe, and the pressure sensor is signal-connected to the controller.

[0015] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0016] (1) This utility model provides a detachable filter cover at the top of the feed hopper. The uniformly distributed filter holes can perform preliminary screening of the input raw materials, effectively intercepting impurities, agglomerated particles and other foreign objects, preventing them from entering the subsequent transportation and production process, and reducing fertilizer quality problems caused by insufficient purity of raw materials from the source.

[0017] Meanwhile, the filter cover adopts a detachable design, which is convenient for staff to disassemble and clean regularly, avoiding the filter hole blockage from affecting the feeding efficiency. It takes into account both the filtration function and maintenance convenience. Furthermore, in conjunction with the magnetic adsorption strip and magnetic groove structure on the edge of the feed hopper, the connection between the filter cover and the feed hopper is tighter, which not only prevents the raw material from leaking out of the gap, but also allows for quick installation and removal of the filter cover, greatly improving the ease of operation. (2) The spiral conveying shaft inside the conveying pipe of this utility model is driven to rotate by the drive component, which can stably push the raw material to the subsequent process, avoiding the problems of raw material accumulation and conveying interruption in the traditional feeding method. In particular, the design of the spiral conveying shaft blade spacing gradually decreasing from the feeding end to the discharging end can moderately compact the raw material during the conveying process, reduce the gap between the raw materials, and make the conveying amount per unit time more uniform, providing a stable guarantee for the raw material ratio in the subsequent production process. In addition, the flow sensor in the middle of the outer side of the conveying pipe is fixed by a bracket. Its probe extends into the pipe to monitor the raw material conveying flow in real time and transmits the signal to the controller. The controller then adjusts the working state of the drive component (such as the rotation speed) according to the flow data to form a closed-loop control, thereby achieving precise control of the raw material conveying volume and avoiding production waste or unstable product quality caused by flow fluctuations.

[0018] (3) The inner wall of the feed hopper of this utility model is provided with 3-6 inclined guide plates, which are evenly distributed along the circumference of the inner wall. This can guide the input raw materials to slide smoothly down the guide plates, avoid the raw materials from accumulating and blocking at the bottom of the feed hopper, and at the same time reduce the friction loss between the raw materials and the hopper wall, thus extending the service life of the feed hopper.

[0019] Meanwhile, the transparent, wear-resistant observation window on the conveying pipe allows staff to visually observe the material conveying status inside the pipe. This enables quick assessment of blockages, material residue, and other issues without disassembling the pipe, reducing inspection and maintenance costs. The vibrating motor on the outside of the feed hopper is electrically connected to the controller. When the material slightly clumps or accumulates, the controller can activate the vibrating motor to loosen the material through vibration, ensuring smooth feeding. This is especially suitable for fertilizer raw materials that are prone to clumping, improving the adaptability of the feeding structure to raw materials with different characteristics.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, a feeding structure for a polyglutamic acid fertilizer production device includes: a feeding hopper 1, a conveying pipe 2, and a driving assembly 3. The bottom of the feeding hopper 1 is connected to the conveying pipe 2 via a connecting flange. A spiral conveying shaft 20 is provided inside the conveying pipe 2. The spiral conveying shaft 20 is driven to rotate by the driving assembly 3. Preferably, the blade spacing of the spiral conveying shaft 20 gradually decreases from the feeding end 22 to the discharge end 23. The spiral conveying shaft 20 inside the conveying pipe 2 is driven to rotate by the driving assembly 3, which can stably push the raw material to the subsequent process and avoid the problems of raw material accumulation and conveying interruption in the traditional feeding method. In particular, the design of the spiral conveying shaft 20 blade spacing gradually decreasing from the feeding end 22 to the discharge end 23 can moderately compact the raw material during the conveying process, reduce the gaps between the raw materials, and make the conveying amount per unit time more uniform, providing a stable guarantee for the raw material ratio in the subsequent production process. In addition, the flow sensor in the middle of the outer side of the conveying pipe 2 is fixed by a bracket. Its probe extends into the pipe to monitor the raw material conveying flow in real time and transmits the signal to the controller 4. The controller 4 then adjusts the working state (such as speed) of the drive component 3 according to the flow data to form a closed-loop control, thereby achieving precise control of the raw material conveying volume and avoiding production waste or unstable product quality caused by flow fluctuations.

[0029] A detachable filter cover 10 is provided on the top of the feed hopper 1. The filter cover 10 has filter holes evenly distributed on it. Specifically, the edge of the filter cover 10 is provided with a magnetic adsorption strip, and a magnetic groove is provided at the corresponding position on the top of the feed hopper 1. The filter cover 10 is detachably connected to the feed hopper 1 through the magnetic adsorption strip. By providing a detachable filter cover 10 on the top of the feed hopper 1, the evenly distributed filter holes can perform preliminary screening of the input raw materials, effectively intercepting impurities, agglomerated particles and other foreign objects, preventing them from entering the subsequent conveying and production stages, and reducing fertilizer quality problems caused by insufficient purity of raw materials from the source.

[0030] Meanwhile, the filter cover 10 adopts a detachable design, which makes it convenient for staff to disassemble and clean it regularly, avoiding the filter holes from being blocked and affecting the feeding efficiency. It takes into account both the filtration function and the convenience of maintenance. Furthermore, in conjunction with the magnetic adsorption strip and magnetic groove structure on the edge of the feed hopper 1, the connection between the filter cover 10 and the feed hopper 1 is tighter, which not only prevents the raw materials from leaking out of the gaps, but also allows for quick installation and removal of the filter cover 10, greatly improving the ease of operation.

[0031] A humidity sensor is installed on the inner wall of the feed hopper 1, and the detection end 11 of the humidity sensor extends into the inside of the feed hopper 1; a flow sensor mounting bracket is installed at the middle position of the outer side of the conveying pipe 2, the flow sensor is fixed by the bracket and its detection end penetrates the pipe wall and extends into the conveying pipe 2, and the humidity sensor is installed on the inner wall of the feed hopper 1, and the detection end extends into the inside to detect the humidity of the raw material in real time.

[0032] The drive assembly 3 is electrically connected to the controller 4. A pressure sensor is provided at the end of the delivery pipe 2. The pressure sensor is connected to the controller 4 via a signal. The humidity sensor and the flow sensor are both electrically connected to the controller 4 via signal cables. The controller 4 receives the electrical signals from the humidity sensor and the flow sensor, thereby driving the drive assembly 3 to work. The controller 4 is connected to an alarm device. When the humidity sensor detects a value exceeding the preset range or the flow sensor detects an abnormal value, the alarm device will sound an alarm.

[0033] In a preferred embodiment of this utility model, the inner wall of the feed hopper 1 is provided with an inclined guide plate 12. There are 3-6 guide plates 12 evenly distributed around the inner wall of the feed hopper 1. The guide plates 12 can guide the raw materials to slide smoothly down the guide plates 12, avoid the raw materials from accumulating and blocking at the bottom of the feed hopper 1, and at the same time reduce the frictional wear between the raw materials and the hopper wall, thus extending the service life of the feed hopper 1.

[0034] In a preferred embodiment of this utility model, the conveying pipe 2 is provided with an observation window 21. The observation window 21 is made of transparent and wear-resistant material, which allows the staff to directly observe the conveying status of the raw materials in the pipe. It can quickly determine whether there are problems such as blockage or raw material residue without disassembling the pipe, thus reducing inspection and maintenance costs. A vibration motor is provided on the outside of the feed hopper 1. The vibration motor is electrically connected to the controller 4. When the raw materials are slightly clumped or accumulated, the controller 4 can start the vibration motor to loosen the raw materials through vibration, ensuring smooth feeding. It is especially suitable for fertilizer raw materials that are prone to clumping, thus improving the adaptability of the feeding structure to raw materials with different characteristics.

[0035] When using this utility model, fertilizer raw materials are fed into the top of the feed hopper 1. The raw materials pass through the filter holes of the filter cover 10, where impurities, clumps, and other foreign objects are intercepted. The fed raw materials are guided by the guide plate 12 and slide smoothly down it into the bottom of the feed hopper 1.

[0036] When the drive assembly 3 is started, the screw conveyor shaft 20 begins to rotate, pushing the raw material into the conveying pipe 2 to be conveyed to the subsequent process. As the blade spacing of the screw conveyor shaft 20 gradually decreases from the feed end 22 to the discharge end 23, the raw material is moderately compacted during the conveying process, reducing the gaps between the raw materials.

[0037] The flow sensor monitors the raw material conveying flow rate in real time and transmits the signal to the controller 4. The controller 4 adjusts the rotation speed of the drive component 3 based on the flow data to achieve precise control of the raw material conveying volume.

[0038] The humidity sensor monitors the humidity of the raw material in the feed hopper 1 in real time. When the humidity value exceeds the preset range or the flow sensor value is abnormal, the alarm device will sound an alarm, and the staff will need to check and handle it in time.

[0039] If slight clumping or accumulation of raw materials is observed through observation window 21, or if controller 4 detects a related abnormal signal, controller 4 can start the vibration motor to loosen the raw materials through vibration, ensuring smooth feeding.

[0040] When problems such as raw material blockage or residue occur, they can be visually assessed through the observation window 21 without disassembling the pipeline, allowing for timely handling.
