Description

Technical Field

[0001] This application relates to the field of fertilizer processing technology, and in particular to a high-efficiency drying device for organic fertilizer production. Background Technology

[0002] Organic fertilizer is mainly produced by processing biological materials, animal and plant waste, and plant residues. It eliminates toxic and harmful substances and is rich in beneficial substances, including various organic acids, peptides, and abundant nutrients such as nitrogen, phosphorus, and potassium. The drying process is an important step in the production of organic fertilizer, and the method of drying is crucial. The drying principle of organic fertilizer is to dry the wet organic fertilizer granules with a moisture content of 50%-55% after granulation through drying equipment until the moisture content is ≤30% to meet the standards for organic fertilizer. For products sold in the short term, a moisture content of ≤30% is sufficient to meet the standard requirements.

[0003] For organic fertilizer products stored for a long time or for further processing into organic-inorganic compound fertilizer granules, the moisture content must be ≤13%. Otherwise, the granules will clump together in the packaging bag during storage. Alternatively, if used for processing into organic-inorganic compound fertilizers, excessive moisture will cause the fertilizer granules to dissolve and soften. Organic fertilizers are generally dried using a drum-type drying cylinder. Hot air circulates inside the drying cylinder, causing the organic fertilizer to rotate and tumble along with the cylinder for drying. However, this process can easily cause organic fertilizer to accumulate inside the cylinder. Due to the high humidity, the organic fertilizer will stick together, affecting the drying effect and resulting in low drying efficiency.

[0004] To address the aforementioned issues, this solution proposes a technical approach: installing hot air ducts inside the drying drum and attaching screens to these ducts. The tumbling organic fertilizer falls onto the screens, which slows its descent, preventing the fertilizer particles from clumping together. The screens break up any clumps of organic fertilizer, thereby improving the drying efficiency of the fertilizer. Summary of the Invention

[0005] The purpose of this application is to break up clumps of organic fertilizer and improve the drying effect of organic fertilizer. Compared with the prior art, it provides a high-efficiency drying device for organic fertilizer production. Hot air pipes are fixedly connected to both sides of the inside of the feeding hopper, and the hot air pipes extend into the inside of the drying drum. A separation screen is fixedly connected between the two hot air pipes. A number of air nozzles are fixedly and equidistantly installed at the bottom of the hot air pipes, and the outlet end of the air nozzles is obliquely facing the separation screen. A sliding rail is fixedly connected to the outside of the two hot air pipes, and a sliding shell is slidably connected to the outside of the sliding rail. A movable end block is fixedly connected to the outside of the sliding shell, and a push rod is hinged to the outside of the movable end block and one end of the sliding rail. A push roller is hinged between the two push rods. A rolling actuating blade is fixedly connected to the inner wall of the drying drum, and the rolling actuating blade corresponds to the push roller. A number of movable crossbars are fixedly connected between the two sliding shells, and a tug spring is fixedly connected to the bottom end of the movable crossbar, and the tug spring corresponds to the top end of the separation screen.

[0006] Two hot air pipes extend into the drying drum, providing hot air for drying. The drying drum rotates and tumbles the organic fertilizer, causing it to fall onto a separating screen. The screen slows the descent of the fertilizer, effectively preventing it from clumping together. Hot air is blown onto the screen, heating it and simultaneously drying any fertilizer particles that have passed through, thus improving the drying effect. Clumps of fertilizer particles remain on the heated screen, where rolling impellers inside the drying drum compress the pushing rollers. The pushing rod and movable end block drive the sliding shell back and forth on the sliding track, which in turn moves the agitator wires on the movable crossbar to agitate the clumps, breaking them up and allowing them to pass through the screen, thus improving the drying quality of the organic fertilizer.

[0007] Furthermore, a hot air blower is fixedly connected to the outside of the feeding hopper car, and the air outlet of the hot air blower is fixedly connected to the hot air pipe. The hot air blower is used to deliver hot air to the hot air pipe, which facilitates the CNC operation of the drying equipment.

[0008] Furthermore, the top surface of the movable crossbar is arched, and the actuating spring is bent in a figure-eight shape. The actuating spring is made of elastic steel wire, which effectively prevents fertilizer particles from staying on the top of the movable crossbar. The figure-eight shaped actuating spring has a large actuation range, and the actuating spring made of elastic steel wire has good wear resistance.

[0009] Furthermore, a fixed baffle is fixedly connected to the other end of the sliding track, and a connecting baffle is fixedly connected between one end of the two sliding shells. A return spring is fixedly connected between the connecting baffle and the fixed baffle. The return spring pushes the connecting baffle to restore the position of the sliding shell, thereby realizing the back-and-forth movement of the sliding shell.

[0010] Furthermore, movable sliders are slidably connected to both ends of the top of the fixed baffle, and a connecting rod is hinged between one side of the two movable sliders and the connecting baffle, so that the connecting baffle, which moves back and forth repeatedly, drives the movable sliders to slide on the fixed baffle by pushing the connecting rod.

[0011] Furthermore, a movable frame is hinged between the other sides of the two movable sliders, and the movable frame has an eight-shaped structure. A connecting pin is inserted into the middle of the movable frame, and a pin plate corresponding to the connecting pin is fixedly connected to the middle of the fixed baffle. An air outlet window is opened on the outside of the discharge hopper. The two movable sliders drive the movable frame to open and close. The operator inserts the connecting pin into the connecting pin through the air outlet window on the discharge hopper to lock the state of the two movable sliders. Indirectly, the state of the sliding shell is locked by locking the connecting baffle, which makes it easy to remove the drying roller from the hot air pipe.

[0012] Furthermore, displacement rollers are fixedly installed at the bottom of both the feeding hopper and the discharging hopper, and a support sleeve is fixedly connected inside the discharging hopper to the corresponding hot air pipe. The feeding hopper and the discharging hopper can be separated from the drying drum, and the support sleeve provides auxiliary support to the end of the hot air pipe to improve the stability of the hot air pipe.

[0013] Optionally, a heat storage pipe is fixedly connected to the bottom end face of the separating screen, and the inside of the heat storage pipe is filled with heat storage oil. The heat storage pipe filled with heat storage oil absorbs heat and distributes the heat evenly to the separating screen, which effectively improves the drying effect of the separating screen on organic fertilizer. At the same time, storing heat effectively alleviates the temperature fluctuation inside the drying drum.

[0014] Furthermore, a heat-conducting vertical rod is fixedly connected to the bottom end of the heat storage pipeline, and the heat-conducting vertical rod is made of aluminum alloy material. The heat-conducting vertical rod effectively improves the heat absorption effect of the heat storage pipeline.

[0015] Furthermore, an oil pipe rotating end is movably connected to one side of the feed hopper car, and the oil pipe rotating end is movably connected to one end of the heat storage pipeline. The oil pipe rotating end is set at a 90-degree bend. By changing the rotation direction of the oil pipe rotating end, it is convenient to carry out oil filling and draining operations in the heat storage pipeline, drain the heat storage oil in the heat storage pipeline, reduce the weight of the hot air pipe, and facilitate the removal of the hot air pipe.

[0016] Compared to existing technologies, the advantages of this application are:

[0017] (1) This solution uses two hot air pipes to extend into the drying drum to provide hot air for drying. The drying drum drives the organic fertilizer to rotate and tumble. The organic fertilizer that falls off the tumbling drum lands on the separating screen. The separating screen slows down the falling force of the organic fertilizer, effectively preventing the organic fertilizer from clumping due to tumbling. The blower blows hot air onto the separating screen, heating the separating screen while drying the organic fertilizer particles that have passed through the separating screen. This effectively improves the hot air drying effect of the fertilizer. The clumps of fertilizer particles remain on the heated separating screen. The rolling blades inside the drying drum squeeze the pushing roller. The pushing rod and the movable end block drive the sliding shell to slide back and forth on the sliding track, which in turn drives the agitator on the movable crossbar to agitate the clumps of fertilizer particles back and forth, breaking up the clumps of fertilizer particles, making it easier for the fertilizer particles to pass through the separating screen and fall, effectively improving the drying quality of the organic fertilizer.

[0018] (2) A hot air blower is fixedly connected to the outside of the feeding hopper car, and the air outlet of the hot air blower is fixedly connected to the hot air pipe. The hot air blower is used to deliver hot air to the hot air pipe, which facilitates the CNC operation of the drying equipment.

[0019] (3) The top surface of the movable crossbar is arched, and the actuating spring is bent in a figure-eight shape. The actuating spring is made of elastic steel wire, which effectively prevents fertilizer particles from staying on the top of the movable crossbar. The figure-eight actuating spring has a large actuating range, and the actuating spring made of elastic steel wire has good wear resistance.

[0020] (4) A fixed baffle is fixedly connected to the other end of the sliding track, and a connecting baffle is fixedly connected between one end of the two sliding shells. A reset spring is fixedly connected between the connecting baffle and the fixed baffle. The reset spring pushes the connecting baffle to restore the position of the sliding shell, thereby realizing the back-and-forth movement of the sliding shell.

[0021] (5) Both ends of the top of the fixed baffle are slidably connected to movable sliders, and one side of the two movable sliders is hinged to the connecting baffle. The connecting baffle, which moves back and forth repeatedly, drives the movable sliders to slide on the fixed baffle by pushing the connecting rod.

[0022] (6) A movable frame is hinged between the other sides of the two movable sliders, and the movable frame has an eight-shaped structure. A connecting pin is inserted in the middle of the movable frame. A pin plate corresponding to the connecting pin is fixedly connected in the middle of the fixed baffle. An air outlet window is opened on the outside of the discharge hopper car. The two movable sliders drive the movable frame to open and close. The operator inserts the connecting pin into the connecting pin through the air outlet window on the discharge hopper car to lock the state of the two movable sliders. The state of the sliding shell is locked indirectly by locking the connecting baffle, which makes it easy to take out the drying drum from the hot air pipe.

[0023] (7) Displacement rollers are fixedly installed at the bottom of both the feeding hopper and the discharging hopper. A support sleeve is fixedly connected inside the discharging hopper to the corresponding hot air pipe. The feeding hopper and the discharging hopper can be separated from the drying drum. The support sleeve provides auxiliary support to the end of the hot air pipe to improve the stability of the hot air pipe.

[0024] (8) A heat storage pipeline is fixedly connected to the bottom end of the separating screen, and the inside of the heat storage pipeline is filled with heat storage oil. The heat storage pipeline filled with heat storage oil absorbs heat and distributes the heat evenly to the separating screen, which effectively improves the drying effect of the separating screen on organic fertilizer. At the same time, the stored heat effectively alleviates the temperature fluctuation inside the drying drum.

[0025] (9) A heat-conducting vertical rod is fixedly connected to the bottom end of the heat storage pipeline, and the heat-conducting vertical rod is made of aluminum alloy material. The heat-conducting vertical rod effectively improves the heat absorption effect of the heat storage pipeline.

[0026] (10) An oil pipe rotating end is movably connected to one side of the feed hopper car, and the oil pipe rotating end is movably connected to one end of the heat storage pipeline. The oil pipe rotating end is set at a 90-degree bend. By changing the rotation direction of the oil pipe rotating end, it is convenient to carry out oil injection and oil discharge operations in the heat storage pipeline, discharge the heat storage oil in the heat storage pipeline, reduce the weight of the hot air pipe, and facilitate the removal of the hot air pipe.

Detailed Implementation

[0039] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0040] Example 1:

[0041] This invention provides a high-efficiency drying device for organic fertilizer production. Please refer to [link / reference]. Figure 1-3 The system includes a drying drum 1, with a feeding hopper 2 and a discharging hopper 3 movably connected to both ends of the drying drum 1. The feeding hopper 2 and discharging hopper 3 are equipped with feeding and discharging hoppers, respectively. Hot air pipes 4 are fixedly connected to both sides of the inside of the feeding hopper 2, extending into the interior of the drying drum 1. A hot air blower 7 is fixedly connected to the outside of the feeding hopper 2, with the outlet of the hot air blower 7 fixedly connected to the hot air pipes 4. Hot air is supplied to the hot air pipes 4 using the hot air blower 7. (The hot air blower 7 is existing equipment, and is described in the art.) (Technicians can choose the appropriate model of equipment themselves, which will not be described in detail here). A separation screen 401 is fixedly connected between the two hot air pipes 4. A number of air nozzles 402 are fixedly and equidistantly installed at the bottom of the hot air pipes 4, and the outlet end of the air nozzles 402 is obliquely facing the separation screen 401. The air nozzles 402 blow hot air onto the separation screen 401 to improve the hot air drying of the falling fertilizer particles, and at the same time heat the separation screen 401, so that the clumped fertilizer particles can be broken and dispersed on the separation screen 401.

[0042] When drying organic fertilizer, the fertilizer is poured from the feed hopper 2 into the drying drum 1. The drying drum 1 drives the fertilizer to rotate and roll. The fertilizer falling down lands on the separating screen 401, which effectively prevents the fertilizer from falling directly back into the drying drum 1 and avoids the fertilizer from agglomerating due to excessive falling force. Fertilizer particles that are not agglomerated can pass directly through the separating screen 401 and continue to fall. The hot air blown out by the air nozzle 402 dries the fertilizer particles with hot air, which effectively improves the drying effect of the effective fertilizer.

[0043] Please see Figure 4-6 Two hot air ducts 4 are externally fixedly connected to sliding rails 5, and sliding shells 501 are slidably connected to the outside of sliding rails 5. Movable end blocks 502 are fixedly connected to the outside of sliding shells 501, and push rods 503 are hinged to the outside of movable end blocks 502 and one end of sliding rails 5. Pushing rollers 504 are hinged between two push rods 503. Rolling actuating blades 505 are fixedly connected to the inner wall of drying drum 1, and the rolling actuating blades 505 correspond to the pushing rollers 504. A plurality of movable crossbars 6 are fixedly connected between the two sliding shells 501 at equal intervals, and the bottom surface of the movable crossbars 6 is... A fixed actuating spring wire 601 is connected, corresponding to the top surface of the separating screen 401. The top surface of the movable crossbar 6 is arched, and the actuating spring wire 601 is bent in a figure-eight shape and is made of elastic steel wire. A fixed baffle 8 is fixedly connected to the other end of the sliding track 5. A connecting baffle 9 is fixedly connected between one end of the two sliding shells 501, and a return spring 10 is fixedly connected between the connecting baffle 9 and the fixed baffle 8. The return spring 10 pushes the connecting baffle 9 to restore the position of the sliding shell 501, thereby realizing the back-and-forth reciprocating movement of the sliding shell 501.

[0044] After the agglomerated fertilizer granules fall onto the separating screen 401, hot air is blown onto the separating screen 401 by the air nozzle 402. The separating screen 401 carries heat that dries the fertilizer granules. During the rotation of the drying drum 1, the rolling actuating blades 505 on the inner wall of the drying drum 1 cyclically squeeze and push the pushing roller 504. Through the pushing rod 503 and the movable end block 502, the sliding shell 501 slides on the sliding track 5. With the cooperation of the return spring 10 between the connecting baffle 9 and the fixed baffle 8, the position of the sliding shell 501 is restored, thereby realizing the back-and-forth movement of the movable crossbar 6 between the two sliding shells 501. Figure 6 As shown, the agitator 601 at the bottom of the movable crossbar 6 agitates the clumped fertilizer particles, thereby breaking up the clumps and effectively improving the drying effect of the clumped organic fertilizer.

[0045] Please see Figure 7-9Both the bottom of the feeding hopper 2 and the discharging hopper 3 are fixedly equipped with displacement rollers. Inside the discharging hopper 3, a support sleeve 11 is fixedly connected to the hot air pipe 4. The feeding hopper 2 and the discharging hopper 3 can be separated from the drying drum 1. The support sleeve 11 provides auxiliary support to the end of the hot air pipe 4, improving its stability. Movable sliders 801 are slidably connected to both ends of the top of the fixed baffle 8, and a connecting rod 802 is hinged between one side of each movable slider 801 and the connecting baffle 9. The connecting baffle 9 drives the movable sliders 801 by pushing the connecting rod 802. The movable slider 801 slides on the fixed baffle 8. A movable frame 803 is hinged between the other sides of the two movable sliders 801. The movable frame 803 has an eight-shaped structure. A connecting pin 804 is inserted into the middle of the movable frame 803. A pin plate 805 corresponding to the connecting pin 804 is fixedly connected to the middle of the fixed baffle 8. An air outlet window is opened on the outside of the discharge hopper 3. The two movable sliders 801 drive the movable frame 803 to open and close. The connecting pin 804 is inserted into the connecting pin 804 to lock the state of the two movable sliders 801.

[0046] After the organic fertilizer drying process is completed, the worker pushes the movable frame 803 through the air outlet window on the discharge hopper 3, pushing the two movable sliders 801 to both ends of the fixed baffle 8. The connecting rod 802 is pulled, pulling the connecting baffle 9 towards the fixed baffle 8, causing the sliding shell 501 to slide on the sliding track 5. This stretches the two push rods 503 and the push roller 504, causing the push roller 504 to move closer to the hot air pipe 4, away from the rolling actuating blade 505. The connecting pin 804 is then inserted into the connecting pin 804, locking the state of the two movable sliders 801. Figure 8 As shown, the two push rods 503 and the push roller 504 are indirectly locked, and then the feed hopper 2 and the discharge hopper 3 are pushed to separate from the drying drum 1, making it easier to pull the hot air pipe 4 out of the drying drum 1, and facilitating the subsequent cleaning of the separation screen 401, such as... Figure 7 As shown.

[0047] Example 2:

[0048] Compared to Example 1, this embodiment mainly adds a heat storage pipe 12. The heat storage pipe 12 absorbs and conducts heat, facilitating uniform heating of the separation screen 401 and improving the drying and separation of agglomerated fertilizer particles on the separation screen 401. Please refer to [link to relevant documentation]. Figure 3 and Figure 10A heat storage pipe 12 is fixedly connected to the bottom end face of the separating screen 401, and the inside of the heat storage pipe 12 is filled with heat storage oil. The heat storage pipe 12, filled with heat storage oil, absorbs heat and distributes the heat evenly onto the separating screen 401, effectively improving the drying effect of the separating screen 401 on organic fertilizer. A heat-conducting vertical rod 1201, made of aluminum alloy, is fixedly connected to the bottom end face of the heat storage pipe 12. The heat-conducting vertical rod 1201 effectively improves the drying effect of the separating screen 401 on organic fertilizer. To enhance the heat absorption effect of the heat storage pipeline 12, an oil pipe rotating end 1202 is movably connected to one side of the feed hopper 2, and the oil pipe rotating end 1202 is movably connected to one end of the heat storage pipeline 12. The oil pipe rotating end 1202 is bent at ninety degrees. By changing the rotation direction of the oil pipe rotating end 1202, the oil filling and oil draining operations of the heat storage pipeline 12 are realized, the heat storage oil in the heat storage pipeline 12 is discharged, the weight of the hot air pipe 4 is reduced, and the hot air pipe 4 is made easier to remove.

[0049] Before drying, rotate the oil pipe rotating end 1202 upwards so that the outlet end of the oil pipe rotating end 1202 faces upwards. Inject the heat storage oil from the oil pipe rotating end 1202 into the heat storage pipe 12. During the drying of organic fertilizer, blow hot air from the air nozzle 402 to the separation screen 401. The heat carried by the hot air is transferred to the heat storage pipe 12 through the heat-conducting vertical rod 1201. The heat storage oil in the heat storage pipe 12 absorbs and stores the heat, and distributes the heat evenly to the separation screen 401 through the heat storage pipe 12, effectively improving the uniform drying of organic fertilizer by the separation screen 401. The heat storage oil in the heat storage pipe 12 stores the heat, effectively alleviating the heat fluctuation inside the drying drum 1 and effectively preventing the change of hot air temperature from affecting the drying effect of organic fertilizer. After the organic fertilizer drying process is completed, rotate the oil pipe rotating end 1202 downwards to facilitate the discharge of the heat storage oil in the heat storage pipe 12, thereby reducing the weight of the hot air pipe 4.

[0050] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
