Description

Technical Field

[0001] This utility model belongs to the technical field of dissolving devices, specifically relating to a water-soluble fertilizer production dissolving device with stirring function. Background Technology

[0002] Water-soluble fertilizers, due to their high nutrient content, rapid dissolution, and high absorption and utilization rate, have become a core fertilizer type in facility agriculture and precision irrigation. In their production process, the dissolution and uniform mixing of solid raw materials (such as nitrogen, phosphorus, and potassium fertilizers, and trace element agents) are crucial to product quality—ensuring complete dissolution without residue to prevent clogging of irrigation equipment, while also guaranteeing uniform nutrient concentration in the solution. Currently, the water-soluble fertilizer dissolving devices used in the industry have significant technical shortcomings in adapting to the needs of large-scale production and improving dissolution efficiency and quality. Specific problems are as follows: Current water-soluble fertilizer production often employs a step-by-step process of crushing and screening followed by dissolving and mixing. Solid raw materials must first be crushed by an independent crusher, then screened to remove large particles and impurities, and finally sent to a dissolving tank for stirring and dissolving. This process not only requires multiple pieces of equipment, resulting in a large footprint and high equipment investment, but also suffers from raw material transfer losses and a long overall process time. Furthermore, the dried raw material particles are prone to agglomeration, which can easily clog the screens during screening, requiring frequent shutdowns for cleaning and severely impacting production continuity. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a water-soluble fertilizer production dissolving device with a stirring function. Compared with traditional devices that first crush and filter the raw materials and then stir and dissolve them, the raw materials enter the device and are directly dissolved and screened in the water environment within the filter frame. The moist particles are more easily dispersed through the filter holes, avoiding the agglomeration problem of dry screening. Compared with traditional screening and filtering mechanisms, the screening difficulty is reduced and the dissolving time is shorter. The overall size of the device is reduced through the built-in design of the filtering mechanism.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a water-soluble fertilizer production dissolving device with stirring function, comprising a dissolving tank, a top cover screwed to the top of the dissolving tank, a motor mounted on the top of the top cover, the output end of the motor connected to a first rotating shaft, a first gear fixedly sleeved on the outer side of the first rotating shaft, the bottom end of the first rotating shaft penetrating the top cover and screwed to a stirring paddle, a filter frame screwed to the inner side of the top cover, filter holes penetrating the bottom of the filter frame, a lifting rod penetrating and sliding between the top and bottom of the top cover, the bottom end of the lifting rod penetrating the bottom of the filter frame and fixedly connected to a first disc, a filter hole clearing rod on the top of the first disc, an annular fixing frame fixedly connected to the top of the lifting rod, an arc-shaped actuating seat fixedly mounted on the inner side of the annular fixing frame, a second rotating shaft rotatably mounted on the top of the top cover, a second gear fixedly connected to the top of the second rotating shaft, an actuating mechanism fixedly sleeved on the outer side of the second rotating shaft, and a valve connected to the bottom of the dissolving tank.

[0005] The beneficial effects of this invention are as follows: This device uses a filter frame to intercept the raw materials entering the dissolving tank. The stirring paddle acts directly inside the filter frame, causing the raw materials to undergo high-intensity stirring, rotation, and friction within the small space of the filter frame. Upon input, the raw materials are immediately agitated and broken down in the water inside the filter frame. Compared to traditional devices that first crush and filter before stirring and dissolving, this device requires less dissolution time. Furthermore, the filter hole cleaning rod cleans the filter holes in real time during the stirring process, ensuring the continuous passage of fine particles after dissolution, while simultaneously pushing clogged particles back into the filter frame for further dissolution. The built-in design of the filtration mechanism also reduces the overall size of the device. The raw materials are dissolved and screened in the water environment within the filter frame, and the moist particles are more easily dispersed through the filter holes, avoiding the agglomeration problem of dry screening. Compared to traditional screening and filtering mechanisms, this also reduces the screening difficulty. Additionally, a single motor can perform both stirring and filter hole cleaning functions, reducing both operating costs and maintenance difficulty.

[0006] For the input of materials: As a further improvement to the above technical solution: the top of the top cover is connected to a water injection pipe joint and a feeding pipe, and the top of the feeding pipe is connected to a hopper.

[0007] The beneficial effects of this improvement are as follows: Before formal operation, connect the water injection pipe joint to the external water supply pipeline, open the water supply valve, and inject clean water into the dissolving tank through the water injection pipe joint. The water level in the dissolving tank is monitored by a liquid level sensor to control the water injection volume. The water supply is stopped when the preset liquid level is reached. Then, the solid raw material of the water-soluble fertilizer to be dissolved is poured into the hopper, and the raw material falls into the filter frame inside the top cover through the feeding pipe.

[0008] As a further improvement to the above technical solution: the filter holes are arrayed at the bottom of the filter frame, and the number and distribution position of the filter hole clearing rods on the first disk are the same as the filter holes, with each filter hole clearing rod aligned with a filter hole.

[0009] To ensure automatic reset of the boom after it rises: As a further improvement to the above technical solution: a sliding rod is fixedly provided on the top of the annular fixing frame, and a guide compression bracket is provided on the top of the top cover. The sliding rod passes through the top plate of the guide compression bracket and is slidably connected to it. A spring is sleeved on the outside of the sliding rod between the top plate of the guide compression bracket and the annular fixing frame.

[0010] The sliding rod at the top of the lifting rod slides upward through its sliding relationship with the guide compression bracket, while the spring between the annular fixed frame and the guide compression bracket is compressed and stores energy. When the semi-annular ramp actuating seat rotates and disengages from the arc-shaped actuating mating seat, the spring releases its elastic force, pushing the annular fixed frame and the lifting rod to quickly return to their original position downward, causing the filter hole unblocking rod to leave the filter hole.

[0011] To drive the boom to rise and fall: As a further improvement to the above technical solution: the actuating mechanism includes a second disc fixedly sleeved on the outside of the second rotating shaft, and a semi-annular ramp actuating seat is provided on the top of the second disc.

[0012] When the second gear drives the second rotating shaft and the outer actuation mechanism to rotate synchronously, the semi-annular ramp actuation seat on the top of the second disc of the actuation mechanism rotates together. When the semi-annular ramp actuation seat rotates to contact the arc surface actuation mating seat on the inner side of the annular fixed frame, the ramp structure generates an upward thrust on the arc surface actuation mating seat, causing the annular fixed frame and the bottom lifting rod to move upward.

[0013] To provide stable support for this device: As a further improvement to the above technical solution: the bottom of the dissolving tank is connected to four bottom supports arranged in a ring.

[0014] The bottom support is used to provide stable support for this device.

[0015] To drive the second gear to rotate: As a further improvement to the above technical solution: the second gear meshes with the first gear.

[0016] When the first gear rotates, it can synchronously drive the second gear to rotate.

[0017] To monitor the water level inside the dissolving tank: As a further improvement to the above technical solution: a liquid level sensor is installed at the bottom of the top cover.

[0018] The level sensor is used to monitor the water level inside the dissolving tank.

[0019] In summary, the beneficial effects of this case are as follows: 1. This device uses a filter frame to trap the raw materials entering the dissolving tank. The stirring paddle acts directly inside the filter frame, causing the raw materials to be stirred, rotated, and rubbed in a small space. After the raw materials are added, they are stirred and broken down in the water inside the filter frame. Compared with traditional devices that first crush and filter and then stir and dissolve, the raw materials are directly dissolved and screened in the water environment inside the filter frame after entering the device. The moist particles are more easily dispersed through the filter holes, avoiding the agglomeration problem of dry screening. Compared with traditional screening and filtering mechanisms, the screening difficulty is reduced and the dissolution time is shorter.

[0020] 2. The filter hole cleaning rod cleans the filter holes in real time during the stirring process, effectively preventing filter hole blockage and ensuring that fine particles of the raw material continue to pass through after dissolution. At the same time, it can push the blocked particles back into the filter frame to continue dissolving.

[0021] 3. This device reduces its overall size through the built-in filtration mechanism.

[0022] 4. This device can achieve both stirring and filter cleaning functions using a single motor, which reduces both operating costs and maintenance difficulty.

[0023] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0026] like Figure 1-7 As shown, a water-soluble fertilizer production dissolving device with stirring function includes a dissolving tank 1. A top cover 2 is screwed to the top of the dissolving tank 1. A motor 7 is mounted on the top of the top cover 2. The output end of the motor 7 is connected to a first rotating shaft 8. A first gear 9 is fixedly sleeved on the outer side of the first rotating shaft 8. The bottom end of the first rotating shaft 8 passes through the top cover 2 and is screwed to a stirring paddle 10. A filter frame 11 is screwed to the inner side of the top cover 2. Filter holes 12 are provided through the bottom of the filter frame 11. A lifting rod 13 passes through and slides between the top and bottom of the top cover 2. The bottom end of the lifting rod 13 passes through the bottom of the filter frame 11 and is fixedly connected to the first disc 14. The top of the first disc 14 is provided with a filter hole unblocking rod 15. The top of the lifting rod 13 is fixedly connected with an annular fixing frame 16. The inner side of the annular fixing frame 16 is fixedly provided with an arc-shaped actuating seat 17. The top of the top cover 2 is rotatably mounted with a second rotating shaft 21. The top of the second rotating shaft 21 is fixedly connected with a second gear 22. The outer side of the second rotating shaft 21 is fixedly sleeved with an actuating mechanism 23. The bottom of the dissolving tank 1 is connected with a valve 26.

[0027] This device uses a filter frame 11 to trap the raw materials entering the dissolving tank 1. The stirring paddle 10 acts directly inside the filter frame 11, causing the raw materials to be intensely stirred, rotated, and rubbed within the small space inside the filter frame 11. Upon input, the raw materials are immediately agitated and broken down in the water inside the filter frame 11. Compared to traditional devices that first crush and filter before agitation and dissolution, this device requires less time for dissolution. Furthermore, the filter hole clearing rod 15 cleans the filter holes 12 in real time during agitation, ensuring the continuous passage of fine particles after dissolution, while simultaneously pushing clogged particles back into the filter frame 11 for further dissolution. The built-in filtration mechanism also reduces the overall size of the device. The raw materials are dissolved and screened in the water environment within the filter frame 11, making it easier for moist particles to disperse and pass through the filter holes, avoiding the agglomeration problem associated with dry screening. Compared to traditional screening and filtration mechanisms, this also reduces screening difficulty. Additionally, a single motor can perform both agitation and filter hole cleaning functions, reducing both operating costs and maintenance difficulty.

[0028] The top of the top cover 2 is connected to a water injection pipe joint 3 and a feeding pipe 4, and the top of the feeding pipe 4 is connected to a hopper 5.

[0029] Before the formal operation, connect the water injection pipe connector 3 to the external water supply pipeline, open the water supply valve, and inject clean water into the dissolving tank 1 through the water injection pipe connector 3. The water level in the dissolving tank 1 is monitored by the liquid level sensor 28 to control the water injection volume. The water supply is stopped after the preset liquid level is reached. Then, the solid raw material of the water-soluble fertilizer to be dissolved is poured into the hopper 5, and the raw material falls into the filter frame 11 inside the top cover 2 through the feeding pipe 4.

[0030] The filter holes 12 are arranged in an array at the bottom of the filter frame 11. The number of filter hole clearing rods 15 and their distribution positions on the first disk 14 are the same as those of the filter holes 12. Each filter hole clearing rod 15 is aligned with one filter hole 12.

[0031] The top of the annular fixing frame 16 is fixedly provided with a sliding rod 18, and the top of the top cover 2 is provided with a guide compression bracket 19. The sliding rod 18 passes through the top plate of the guide compression bracket 19 and is slidably connected to it. A spring 20 is sleeved on the outside of the sliding rod 18 between the bottom of the top plate of the guide compression bracket 19 and the annular fixing frame 16.

[0032] The sliding rod 18 at the top of the lifting rod 13 slides upward through the sliding relationship with the guide compression bracket 19, while the spring 20 between the annular fixed frame 16 and the guide compression bracket 19 is compressed and stored. When the semi-annular ramp actuating seat 25 rotates and disengages from the arc surface actuating mating seat 17, the spring 20 releases its elastic force, pushing the annular fixed frame 16 and the lifting rod 13 to quickly return to their original position downward, so that the filter hole unblocking rod 15 leaves the filter hole 12.

[0033] The actuating mechanism 23 includes a second disc 24 fixedly sleeved on the outside of the second rotating shaft 21, and a semi-annular ramp actuating seat 25 is provided on the top of the second disc 24.

[0034] When the second gear 22 drives the second rotating shaft 21 and the outer actuating mechanism 23 to rotate synchronously, the semi-annular ramp actuating seat 25 on the top of the second disc 24 of the actuating mechanism 23 rotates together. When the semi-annular ramp actuating seat 25 rotates to contact the arc surface actuating mating seat 17 on the inner side of the annular fixed frame 16, the ramp structure generates an upward thrust on the arc surface actuating mating seat 17, which drives the annular fixed frame 16 and the bottom lifting rod 13 to move upward.

[0035] The bottom of the dissolving tank 1 is connected to four bottom supports 27 arranged in a ring.

[0036] The bottom bracket 27 is used to provide stable support for this device.

[0037] The second gear 22 meshes with the first gear 9.

[0038] When the first gear 9 rotates, it can synchronously drive the second gear 22 to rotate.

[0039] A liquid level sensor 28 is installed at the bottom of the top cover 2.

[0040] The level sensor 28 is used to monitor the water level inside the dissolving tank 1.

[0041] Working principle and usage process of this utility model: Before the formal operation, connect the water injection pipe connector 3 to the external water supply pipeline, open the water supply valve, and inject clean water into the dissolving tank 1 through the water injection pipe connector 3. The water level in the dissolving tank 1 is monitored by the liquid level sensor 28 to control the water injection volume. The water supply is stopped after the preset liquid level is reached.The solid raw material of the water-soluble fertilizer to be dissolved is then poured into the hopper 5. The raw material falls into the filter frame 11 inside the top cover 2 through the feeding pipe 4. At this time, the raw material comes into contact with the clean water in the filter frame 11 and begins to be initially moistened and dissolved. The motor 7 is started by the control platform. The motor 7 drives the first rotating shaft 8 to rotate. The stirring paddle 10 connected to the bottom of the first rotating shaft 8 rotates in the dissolving tank 1, stirring the clean water and the water-soluble fertilizer raw material. On the one hand, it breaks up the lumpy raw material and accelerates its fusion with the water. On the other hand, it forms a local vortex, which causes the raw material particles to continuously pass through the filter holes 12 and enter the lower area of ​​the dissolving tank 1 under the action of the water flow. At the same time, it ensures that the undissolved particles continue to be stirred in the filter frame. Meanwhile, the first gear 9 on the outside of the first rotating shaft 8... The second gear 22, which is engaged with the first disc, rotates. The second gear 22 drives the second shaft 21 and the outer actuating mechanism 23 to rotate synchronously. The semi-annular ramp actuating seat 25 on the top of the second disc 24 of the actuating mechanism 23 rotates accordingly. When the semi-annular ramp actuating seat 25 rotates to contact the arc-shaped actuating mating seat 17 on the inner side of the annular fixed frame 16, the ramp structure generates an upward thrust on the arc-shaped actuating mating seat 17, causing the annular fixed frame 16 and the bottom lifting rod 13 to move upward. The sliding rod 18 at the top of the lifting rod 13 slides upward through its sliding relationship with the guide compression bracket 19, simultaneously compressing and storing the spring 20 between the annular fixed frame 16 and the guide compression bracket 19. Meanwhile, the first disc 14 is... The lifting rod 13 moves upward, and the filter hole clearing rod 15 on the top of the first disc 14 moves upward simultaneously, inserting into the filter hole 12 and extending to the top of the filter frame 11, pushing out the raw material particles blocked in the filter hole 12, thus realizing the automatic clearing and anti-clogging function of the filter hole. When the semi-annular inclined actuating seat 25 rotates and disengages from the arc surface actuating seat 17, the spring 20 releases its elastic force, pushing the annular fixing frame 16 and the lifting rod 13 to quickly return to their original position, causing the filter hole clearing rod 15 to leave the filter hole 12. Throughout the process, the raw material completes a continuous process of "wetting - stirring and crushing - dissolving - sieving" within the filter frame 11: the dissolved solution and fine particles enter the dissolving tank 1 through the filter hole 12, and part of the water flow power transmission of the stirring paddle 10... The raw materials are fed into the tank, forming a continuous circulation, which further mixes the solution evenly. The raw materials that do not pass through the filter holes 12 are continuously stirred in the filter frame 11 until they reach the sieve particle size and pass through the filter holes 12. In summary, this device intercepts the raw materials entering the dissolving tank 1 through the filter frame 11, and the stirring paddle 10 acts directly inside the filter frame 11. After the raw materials are added, they are stirred and broken in the water inside the filter frame 11. Compared with the traditional device that first crushes and filters and then stirs and dissolves, the dissolving time of this device is shorter. In addition, the filter hole clearing rod 15 cleans the filter holes 12 in real time during the stirring process, ensuring that the fine particles after the raw materials are dissolved continue to pass through, while pushing the blocked particles back into the filter frame 11 to continue dissolving.Meanwhile, the built-in design of the filtration mechanism also reduces the overall size of the device. The raw materials are dissolved and screened in the water environment within the filter frame 11. The moist particles are more easily dispersed through the filter holes, avoiding the agglomeration problem of dry screening. Compared with traditional screening and filtration mechanisms, it also reduces the screening difficulty. At the same time, a single motor can realize both stirring and filter hole cleaning functions, which reduces both operating costs and maintenance difficulty. After dissolution, the water-soluble fertilizer solution can be exported and the device can be cleaned. Open the valve 26 at the bottom of the dissolving tank 1, and the dissolved water-soluble fertilizer solution is exported to the storage container or subsequent processing equipment through valve 26. After export, close valve 26, and inject clean water into the dissolving tank 1 again through the water injection pipe joint 3. Start the motor 7 to drive the stirring paddle to rotate, and rinse the inner wall of the dissolving tank 1, the stirring paddle 10, and the filter frame 11. The rinsing wastewater is discharged through the valve. If there are many impurities trapped in the filter frame 11, the connecting bolts between the top cover 2 and the dissolving tank 1 can be unscrewed, the top cover 2 can be removed, and the filter frame 11 can be cleaned separately. After cleaning, it can be reassembled to ensure the cleanliness and dissolving efficiency of the device when it is used next time.
