Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pesticide processing equipment, in particular to a diuron mother liquor treatment device. BACKGROUND

[0002] Diuron is a broad-spectrum herbicide commonly used in agricultural production. Diuron mother liquor refers to a water solution containing diuron main components, generally 20%-41% diuron water solution, used for weed spraying in farmland, woodland, grassland, orchard, and flowers. When using diuron mother liquor, it is necessary to strictly follow the concentration and dosage provided in the instruction manual for preparation and use, to prevent adverse effects on farmland, environment, and human health.

[0003] The production of diuron mother liquor includes the following main processing procedures: 1. solid raw material preparation; 2. reaction preparation; 3. processing filtration: filtering, centrifuging, and separating the mother liquor after reaction to remove impurities and insoluble substances; 4. packaging and storage.

[0004] Currently, in the production of diuron mother liquor, a centrifugal reaction kettle is used to mix diuron solid raw materials with liquid raw materials for reaction, which mainly consists of an outer barrel and an inner barrel rotatingly installed in the outer barrel. The inner barrel is provided with filter holes. After the reaction of diuron solid raw materials with liquid raw materials is completed, the inner barrel of the reaction kettle rotates in the reaction kettle, driving the diuron solid raw materials to rotate in the inner barrel, using centrifugal force to remove the liquid raw materials adsorbed in the solid raw materials, and leaving the solid raw materials, impurities, and insoluble substances in the inner barrel to achieve the filtration of the solid raw materials, impurities, and insoluble substances.

[0005] However, the centrifugal reaction kettle has the following defects when removing the liquid raw materials adsorbed in the solid raw materials: the solid raw materials, impurities, and insoluble substances are left in the inner barrel, making it inconvenient to clean the raw materials, impurities, and insoluble substances, and affecting the treatment efficiency of diuron mother liquor.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0042] To address the technical problems in the background art, the following diuron mother liquor treatment device is provided:

[0043] Combination Figures 1-11 As shown, the present invention provides a diuron mother liquor treatment device, comprising a treatment tank 1 and an annular filter barrel 3; the top of the treatment tank 1 is open, and a support frame is fixed at the bottom of the treatment tank 1 for supporting it; a drain pipe 11 connected to the inside is fixedly installed at the bottom of the side wall of the treatment tank 1, and a drain valve is installed on the drain pipe 11; a rotating shaft 12 is rotatably installed inside the treatment tank 1, and the rotating shaft 12 moves through the bottom of the treatment tank 1; a driving component 2 for driving the rotating shaft 12 to rotate is installed at the bottom of the treatment tank 1; several openings are provided on the side wall of the annular filter barrel 3. Each filter has a square hole 32, which forms multiple sets of filter hole units arranged in a ring array on the annular filter barrel 3. Each set of filter hole units includes multiple filter square holes 32 arranged in a vertical array. A connecting block 31 is installed at the bottom of the annular filter barrel 3, and the bottom of the connecting block 31 has an insertion groove 311. An insertion rod 121 is fixed at the top of the rotating shaft 12, and the insertion rod 121 can be inserted into the insertion groove 311. When diuron solid raw material and liquid raw material react and mix, the diuron solid raw material and liquid raw material are poured into the annular filter barrel 3. After mixing, the ball valve is opened to discharge the liquid raw material. The drive unit 2 is controlled to rotate the shaft 12 inside the processing tank 1, which in turn drives the annular filter 3 to rotate. This causes the solid raw material, impurities, and insoluble matter inside the annular filter 3 to centrifuge and dehydrate. The dehydrated solid raw material, impurities, and insoluble matter remain inside the annular filter 3. The outer wall of the processing tank 1 is symmetrically fixed with two vertically oriented first electric cylinders 13. The piston rods of the two first electric cylinders 13 extend to the top of the processing tank 1 and are fixedly connected to the mounting plate 14. A first telescopic rod 141 is fixedly installed on the mounting plate 14. The telescopic end of the first telescopic rod 141 extends into the interior of the processing box 1, and a first sealing mechanism 4 for sealing the top of the annular filter barrel 3 is installed on the telescopic end of the first telescopic rod 141. A second electric cylinder 15 in a vertical direction is installed on the mounting plate 14. The piston rod of the second electric cylinder 15 is connected to the first sealing mechanism 4. A fixing mechanism 5 acting on the annular filter barrel 3 is installed on the first sealing mechanism 4, and the fixing mechanism 5 is used to fix the first sealing mechanism 4 and the annular filter barrel 3.

[0044] The design of the insertion slot 311 and insertion rod 121 allows for a detachable connection between the annular filter barrel 3 and the rotating shaft 12. The annular filter barrel 3 is inserted inside the processing box 1. Using the fixing mechanism 5, the solid and liquid raw materials of diuron react and mix. After mixing, the solid raw materials, impurities, and insoluble substances inside the annular filter barrel 3 undergo centrifugal rotation for dehydration. The solid raw materials, impurities, and insoluble substances remaining inside the inner barrel after dehydration are fixed by the fixing mechanism 5. The first electric cylinder 13 moves the mounting bracket vertically upward, causing the first sealing mechanism 4 to shift. Thus, the annular filter barrel is fixed by the fixing mechanism 5. 3. The filter is lifted to the top of the treatment tank 1. At this point, the annular filter 3 can be disassembled to clean the solid raw materials, impurities, and insoluble matter remaining inside the annular filter 3. This facilitates the cleaning of raw materials, impurities, and insoluble matter and improves the treatment efficiency of diuron mother liquor. Through the design of the first sealing mechanism 4, the top of the annular filter 3 can be sealed, thereby effectively preventing the rotating shaft 12 from rotating inside the treatment tank 1 and driving the annular filter 3 to rotate. This prevents the solid raw materials, impurities, and insoluble matter inside the annular filter 3 from being released from the top of the annular filter 3 during centrifugal dehydration.

[0045] In this embodiment, the rotating shaft 12 is mounted on the bottom of the processing box 1 via a sealed bearing, and the driving component 2 includes a motor 21 fixedly mounted on the bottom of the processing box 1. The output shaft of the motor 21 is connected to the rotating shaft 12 via a bevel gear assembly 22.

[0046] When in use, the control motor 21 is turned on, and the output shaft of the motor 21 rotates, which drives the rotating shaft 12 to rotate inside the processing box 1 through the bevel gear assembly 22, making it easy to control; the design of the sealed bearing increases the sealing between the rotating shaft 12 and the processing box 1.

[0047] In this embodiment, the first sealing mechanism 4 includes a connecting plate 41 fixedly connected to the telescopic end of the first telescopic rod 141. An annular sealing plate 42 for sealing the opening end of the annular filter barrel 3 is installed on the connecting plate 41, and a fixing mechanism 5 is installed on the annular sealing plate 42.

[0048] In use, controlling the second electric cylinder 15 causes the connecting plate 41 to move along the first telescopic rod 141 toward the filter barrel 3, which allows the annular sealing plate 42 to seal the top opening of the filter barrel 3, making it easy to control.

[0049] In this embodiment, the fixing mechanism 5 includes three mounting blocks 51 arranged in a ring array on the annular sealing plate 42. A first electric push rod 52 in a horizontal direction is fixedly mounted on the mounting block 51. The piston rod of the first electric push rod 52 is fixedly connected to a fixing block 53. A second electric push rod 54 in a vertical direction is fixedly mounted on the fixing block 53. The piston rod of the second electric push rod 54 is fixedly mounted with a clamping plate 55 that can contact the annular filter barrel 3.

[0050] In use, the first electric push rod 52 and the second electric push rod 54 work together to move the fixing block 53 closer to or further away from the annular filter barrel 3. Then, the second electric push rod 54 works together to move the clamping plate 55 up and down in the vertical direction, so that the clamping plate 55 comes into contact with the annular filter barrel 3. This achieves the effect of fixing the annular filter barrel 3 with the three clamping plates 55. The operation is simple. Example 2

[0051] like Figures 1-11 As shown, based on the above embodiments, this embodiment further provides the following:

[0052] In this embodiment, the annular sealing plate 42 can be inserted into the annular filter barrel 3. When the annular sealing plate 42 is inserted into the annular filter barrel 3, the outer side wall of the annular sealing plate 42 is in contact with the inner side wall of the annular filter barrel 3. Rubber plates 551 are fixedly installed on the side of the three clamping plates 55 that are close to each other.

[0053] When centrifugally dehydrates solid raw materials, impurities, and insoluble substances, the connecting plate 41 moves along the first telescopic rod 141 into the annular filter barrel 3 via the second electric cylinder 15. This allows the annular sealing plate 42 to be inserted into the annular filter barrel 3, thereby squeezing the fixed raw materials, impurities, and insoluble substances inside the annular filter barrel. This allows the solid raw materials, impurities, and insoluble substances to be dehydrated by centrifugation in the annular filter barrel 3 while being squeezed for dehydration, further improving the dehydration effect of diuron mother liquor.

[0054] The design of the rubber plate 551 increases the friction between the rubber plate 551 and the annular filter barrel 3 when the clamping plate 55 contacts the annular filter barrel 3, thereby increasing the fixing effect on the annular filter barrel 3.

[0055] In this embodiment, the connecting block 31 is fixedly mounted at the eccentric bottom of the annular filter barrel 3. The annular sealing plate 42 has a cavity 421 inside. The top of the annular sealing plate 42 has a through hole 422 that communicates with the cavity 421. The connecting plate 41 is located inside the cavity 421. The first telescopic rod 141 and the second electric cylinder 15 both pass through the through hole 422 and are fixedly connected to the connecting plate 41. The top wall and bottom wall of the cavity 421 are both equipped with balls 423 that contact the connecting plate 41.

[0056] The rotating shaft 12 rotates, causing the annular filter barrel 3 to move in a circular motion around the rotating shaft 12. Solid raw materials, impurities and insoluble substances rotate inside the annular filter barrel 3, further improving the desiccation effect of diuron mother liquor.

[0057] The design of the ball bearing 423 reduces the friction between the connecting plate 41 and the annular sealing plate 42, thereby increasing the service life of the equipment. Example 3

[0058] like Figures 1-11 As shown, based on the above embodiments, this embodiment further provides the following:

[0059] In this embodiment, a second telescopic rod 6 in a vertical direction is fixedly provided on the top of the annular sealing plate 42, and a mounting block 51 is installed on the top of the second telescopic rod 6. A third electric push rod 7 connected to the mounting block 51 is fixedly installed on the top of the annular sealing plate 42. A cleaning mechanism 8 for cleaning the filter square hole 32 is installed at the bottom of the clamping plate 55. A third electric cylinder 424 in a vertical direction is fixedly installed on the annular sealing plate 42. The piston rod of the third electric cylinder 424 can penetrate the annular sealing plate 42 and abut against the connecting plate 41.

[0060] The design of the cleaning mechanism 8 effectively prevents solid raw materials, impurities, and insoluble substances from clogging the inside of the filter square holes 32 during the dehydration process inside the annular filter barrel 3, thus affecting the discharge of liquid through the filter square holes 32.

[0061] In this embodiment, the cleaning mechanism 8 includes a vertical plate 81 fixed to the bottom of the clamping plate 55. A receiving cavity 811 is provided in the vertical plate 81. Multiple cleaning rods 82 are movably inserted through the vertical plate 81 and located in the receiving cavity 811. The multiple cleaning rods 82 are arranged in a vertical linear array. One end of the cleaning rod 82 passes through the side of the vertical plate 81 near the filter barrel 3, and the cleaning rod 82 can be inserted into the filter square hole 32. A spring 83 connected to the cleaning rod 82 is fixed in the receiving cavity 811. The side wall of the cleaning rod 82 away from the spring 83 is arc-shaped. Specifically, when the motor 21 drives the annular filter barrel 3 to rotate through the rotating shaft 12, the annular filter barrel 3 contacts the arc surface of the cleaning rod 82.

[0062] When the annular filter barrel 3 rotates, it contacts the arc surface of the cleaning rod 82. When the cleaning rod 82 is located at the filter square hole 32 on the annular filter barrel 3, the spring 83 returns to its natural state, pushing the cleaning rod 82 into the filter square hole 32. The cleaning rod 82 can then clean the inside of the filter square hole 32. When the annular filter barrel 3 rotates and contacts the arc surface of the cleaning rod 82, the cleaning rod 82 is inserted into the filter square hole 32. The rotation of the annular filter barrel 3 can push the cleaning rod 82 to slide into the receiving cavity 811.

[0063] In this embodiment, the cleaning rod 82 has a through cavity 821 that communicates with the receiving cavity 811. A one-way valve 822 is fixed in the through cavity 821, and an inlet pipe 84 that communicates with the receiving cavity 811 is fixedly installed on the top of the upright plate 81.

[0064] The design of the inlet pipe 84 allows it to be connected to a liquid transfer pump during use. The liquid transfer pump delivers liquid to the inlet pipe 84, which then enters the receiving cavity 811 and subsequently the through cavity 821. This opens the one-way valve 822, allowing the liquid to be sprayed out of the cleaning rod 82. The one-way valve 822 is designed to prevent solid raw materials, impurities, and insoluble substances in the filter square hole 32 from entering the receiving cavity 811 through the through cavity 821 when the cleaning rod 82 is inserted into the filter square hole 32.

[0065] In this embodiment, a second sealing mechanism 9 for sealing its opening is installed on the processing box 1; the second sealing mechanism 9 includes a third telescopic rod 91 symmetrically and horizontally fixedly installed on the outer wall of the processing box 1, and two top plates 92 symmetrically arranged on the top of the processing box 1. The two top plates 92 are respectively fixedly connected to the telescopic ends of the two third telescopic rods 91. A fourth electric push rod 93 horizontally connected to the top plates 92 is fixedly installed on the processing box 1. Two grooves are constructed on the opposite sides of the two top plates 92. When the two top plates 92 are in contact, they seal the top opening of the processing box 1. When the two top plates 92 are in contact, the two grooves on the two top plates 92 are respectively in contact with the cross sections of the first telescopic rod 141 and the second electric cylinder 15. Each top plate 92 has an arc-shaped groove 921 on its top. The two arc-shaped grooves 921 are symmetrically arranged. Specifically, when the two top plates 92 are in contact, the two arc-shaped grooves 921 form a circle. An arc-shaped limiting plate 922 is rotatably connected to the top plate 92 and located in the arc-shaped groove 921. The top of the arc-shaped limiting plate 922 is inclined outward. When the two arc-shaped limiting plates 922 are in contact, the two arc-shaped limiting plates 922 form a circle. An arc-shaped external toothed ring 923 is fixed on the outer side of the arc-shaped limiting plate 922. A motor 94 is fixedly installed on the top of one of the top plates 92. The output shaft of the motor 94 is fixedly installed with a drive gear 95 that meshes with the arc-shaped external toothed ring 923. A limiting gear 96 is coaxially fixed to the bottom of the filter barrel 3. An arc-shaped internal toothed rack 924 that can mesh with the limiting gear 96 is fixed on the inner side of the arc-shaped limiting plate 922.

[0066] Utilizing the design of the second sealing mechanism 9, when the annular filter barrel 3 rotates inside the processing box 1 to dehydrate solid raw materials, impurities, and insoluble substances, the two fourth electric push rods 93 are controlled to bring the two top plates 92 closer together, so that the two top plates 92 fit together and seal the top opening of the processing box 1, thereby effectively preventing the liquid from splashing out through the top opening of the processing box 1 when the annular filter barrel 3 rotates to dehydrate solid raw materials, impurities, and insoluble substances.

[0067] When cleaning solid raw materials, impurities and insoluble substances inside the annular filter barrel 3, the annular filter barrel 3 is lifted to the top of the treatment box 1, which can achieve the effect of spray cleaning on the outside of the annular filter barrel 3 and cleaning inside the filter square holes 32, further facilitating the cleaning of the annular filter barrel 3 and further improving the treatment efficiency of diuron mother liquor.

[0068] Working principle and usage process of this invention:

[0069] When diuron solid raw material and liquid raw material react and mix, the first electric cylinder 13 moves the mounting frame vertically upward, and the second electric cylinder 15 moves the connecting plate 41 closer to the mounting plate 14 along the first telescopic rod 141, causing the annular sealing plate 42 to move so that the annular sealing plate 42 is above the processing box 1. At this time, diuron solid raw material and liquid raw material can be fed into the annular filter barrel 3 for mixing. After mixing is completed, the ball valve is opened to discharge the liquid raw material, while the solid raw material, impurities and insoluble matter remain inside the annular filter barrel 3. With the cooperation of the first electric cylinder 13 and the second electric cylinder 15, the opening of the annular filter barrel 3 is sealed by the annular sealing plate 42. The motor 21 is turned on, and the output shaft of the motor 21 rotates, which drives the rotating shaft 12 to rotate in the processing box 1 through the bevel gear assembly 22. This causes the solid raw materials, impurities and insoluble matter in the annular filter barrel 3 to be centrifugally rotated and dehydrated. The solid raw materials, impurities and insoluble matter remain inside the annular filter barrel 3 after dehydration. The annular sealing plate 42 seals the opening of the annular filter barrel 3 to prevent the solid raw materials, impurities and insoluble matter from falling out from the top of the annular filter barrel 3. After dehydration, the second electric cylinder 15 positions the annular sealing plate 42 above the processing box 1. Then, with the cooperation of the first electric push rod 52 and the second electric push rod 54, the fixing block 53 moves closer or further away from the annular filter barrel 3. With the cooperation of the second electric push rod 54, the clamping plate 55 moves up and down in the vertical direction, thus realizing the dehydration of the filter barrel 3. The clamping plates 55 abut against the annular filter barrel 3, thus fixing the annular filter barrel 3 through the three clamping plates 55. The first electric cylinder 13 moves the mounting frame vertically upward, lifting the annular filter barrel 3 to the top of the processing box 1. At this time, the annular filter barrel 3 can be disassembled to clean the fixed raw materials, impurities, and insoluble substances remaining inside the annular filter barrel 3. Furthermore, when the motor 21 is controlled to rotate the shaft 12 inside the processing box 1, and the solid raw materials, impurities, and insoluble substances are centrifuged and dehydrated, the second electric cylinder 15 moves the connecting plate 41 along the first telescopic rod 141 into the annular filter barrel 3, allowing the annular sealing plate 42 to be inserted into the annular filter barrel 3. This squeezes the fixed raw materials, impurities, and insoluble substances inside the annular filter barrel, allowing the solid raw materials, impurities, and insoluble substances to be centrifuged and dehydrated simultaneously, further improving the dehydration effect of diuron mother liquor.

[0070] By fixing the connecting block 31 to the eccentric bottom of the annular filter barrel 3, the rotating shaft 12 rotates, causing the annular filter barrel 3 to move in a circular motion around the rotating shaft 12. Solid raw materials, impurities, and insoluble substances rotate inside the annular filter barrel 3, further improving the desiccant mother liquor removal effect. Utilizing the design of the connecting plate 41 located within the cavity 421, when the second electric cylinder 15 moves the connecting plate 41 along the first telescopic rod 141 into the annular filter barrel 3, the first electric push rod 52 is controlled to move the fixing block 53 away from the mounting block 51 and into contact with the inner wall of the treatment box 1. This places the clamping plate 55 outside the annular filter barrel 3, allowing the annular sealing plate 42 to move horizontally, ensuring that the annular sealing plate 42 and the treatment box 1 are on the same axis. In the linear direction, the second electric actuator 54 moves the clamping plate 55 vertically downward to the outside of the annular filter barrel 3. Then, the first electric actuator 52 is controlled to move the fixing block 53 closer to the mounting block 51, so that both clamping plates 55 are in contact with the outer wall of the annular filter barrel 3. This will cause the annular sealing plate 42 to be in the same axial direction as the annular filter barrel 3. At this time, the second electric cylinder 15 can move the connecting plate 41 along the first telescopic rod 141 into the annular filter barrel 3, and the third electric actuator 7 can move the mounting block 51 vertically upward, so that the first electric actuator 52 is above the annular filter barrel 3. This allows the solid raw materials, impurities and insoluble substances to rotate and be dehydrated in the annular filter barrel 3, while being squeezed and dehydrated.

[0071] Utilizing the design of the cleaning mechanism 8, solid raw materials, impurities, and insoluble substances rotate within the annular filter barrel 3 for dehydration. During the dehydration process, the first electric push rod 52 moves the fixing block 53 away from the mounting block 51, preventing the rubber plate 551 from contacting the annular filter barrel 3. The third electric cylinder 424 is controlled to have its piston rod penetrate the annular sealing plate 42 and abut against the connecting plate 41, thus fixing the connecting plate 41 and the annular sealing plate 42. When the annular filter barrel 3 rotates, it rotates between the three clamping plates 55 and abuts against the cleaning square rod 82 on the vertical plate 81. The spring 83 deforms, and the annular filter barrel 3 contacts the arc surface of the cleaning square rod 82 as it rotates. When the cleaning square rod 82 is located at the filter square hole 32 on the annular filter barrel 3, the spring 83 returns to its natural state, pushing... The cleaning rod 82 is inserted into the filter square hole 32, allowing for cleaning of the inside of the filter square hole 32. This effectively prevents solid raw materials, impurities, and insoluble substances from clogging the filter square hole 32 during the dehydration process inside the annular filter barrel 3, thus ensuring the liquid can be discharged through the filter square hole 32. Furthermore, the design of the cleaning rod 82 allows the mounting plate 14 to move vertically upwards when the first electric cylinder 13 lifts the annular filter barrel 3 to the top of the processing box 1. This allows the annular filter barrel 3 to rotate within the processing box 1, enabling the cleaning rod 82 to be inserted into the filter square hole 32. When lifting the annular filter barrel 3, the cleaning rod 82 limits its movement, effectively preventing the annular filter barrel 3 from slipping out from between the three clamping plates 55.

[0072] Utilizing the design of the second sealing mechanism 9, when the annular filter barrel 3 rotates within the processing chamber 1 to dehydrate solid raw materials, impurities, and insoluble substances, the two fourth electric actuators 93 are controlled to bring the two top plates 92 closer together, causing them to adhere and seal the top opening of the processing chamber 1. This effectively prevents liquid from splashing out through the top opening of the processing chamber 1 during the rotation of the annular filter barrel 3 to dehydrate solid raw materials, impurities, and insoluble substances. When cleaning solid raw materials, impurities, and insoluble substances inside the annular filter barrel 3, the two first electric cylinders 13 are controlled to clean the annular filter. When the barrel 3 is lifted to the top of the processing box 1, the two fourth electric actuators 93 are controlled to move the two top plates 92 away from each other and slide to the sides of the processing box 1 respectively. After the annular filter barrel 3 is lifted to the top of the processing box 1, the two fourth electric actuators 93 are controlled to move the two top plates 92 closer together, so that the two top plates 92 are in contact, the two arc grooves 921 form a circle, and the two arc limiting plates 922 are in contact. The two first electric cylinders 13 are controlled to move the mounting plate 14 vertically downward. When the annular filter barrel 3 contacts the top arc surface of the arc limiting plate 922, the first electric actuator 52 is controlled. The fixed block 53 is displaced away from the mounting block 51. Through the cooperation of the third electric push rod 7 and the second electric push rod 54, the annular sealing plate 42 is positioned above the annular filter barrel 3, and multiple cleaning rods 82 are positioned outside the annular filter barrel 3. The limiting of the annular filter barrel 3 is removed, and the annular filter barrel 3 slides downward along the top arc surface of the arc-shaped limiting plate 922, so that the limiting gear 96 at the bottom of the annular filter barrel 3 engages with the arc-shaped internal racks 924 on the inner side of the two arc-shaped limiting plates 922. At this time, the control motor 94 is turned on, and the output shaft of the motor 94 rotates, driving the drive gear 95. The rotation of the ring filter 3 causes the two arc-shaped external toothed rings 923 to drive the two arc-shaped limiting plates 922 to rotate sequentially within the two arc-shaped grooves 921, thereby rotating the annular filter barrel 3. A liquid pump then delivers liquid to the inlet pipe 84, allowing the liquid to enter the receiving cavity 811 and be sprayed out through the passage 821 towards the outside of the cleaning rod 82. The rotation of the annular filter barrel 3 achieves a spray cleaning effect on the outside of the annular filter barrel 3 and cleans the inside of the filter square holes 32, further facilitating the cleaning of the annular filter barrel 3 and improving the efficiency of treating diuron mother liquor.
