Description

Technical Field

[0001] This utility model belongs to the field of filtration device technology, specifically a filtration device for pesticide formulation production. Background Technology

[0002] Filtration devices used in pesticide formulation production, namely pesticide filters, are multi-purpose filtration equipment characterized by novel structure, small size, simple and flexible operation, energy saving, high efficiency, closed operation, and strong adaptability. Pesticide filters are widely used in the production and processing of pesticide formulations to remove impurities and particles from liquids, ensuring product quality and stability. Filtration devices used in pesticide formulation production are an indispensable and important piece of equipment in the pesticide production process. When selecting and using them, factors such as production needs, material characteristics, and price must be fully considered to ensure product quality and stability.

[0003] An existing patent (publication number: CN218686738U) discloses a filtration device for pesticide formulation production. This filtration device can quickly remove the filter plate from the fixed base for cleaning. After cleaning, the filter plate is placed between two fixed bases, and the adjusting head is turned to rotate the locking head into the fixing groove on the filter plate, thus quickly fixing the filter plate to the fixed base. The operation is convenient and allows personnel to easily clean the filter plate. However, when disassembling the filter plate, the operator needs to put their hands inside the device, which can easily cause the operator's arms to be contaminated with pesticide formulations, affecting the operator's health. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a filtration device for pesticide formulation production, which effectively solves the problem that when disassembling the filter plate of the filtration device, the operator needs to put his / her hand into the inside of the device, which can easily cause the operator's arm to be contaminated with pesticide formulations and affect the operator's health.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for pesticide formulation production, comprising a filter tank, four support legs fixedly installed at equal intervals in a ring at the bottom of the filter tank, a movable cover on the top of the filter tank, a support frame fixedly installed on the upper rear part of the filter tank, a drive motor fixedly installed on one side of the support frame, a transmission component at the output end of the drive motor, two transmission bars symmetrically fixedly installed on the inner wall of the filter tank, an installation ring inside the filter tank, a receiving hopper fixedly installed on the top of the installation ring, a connecting ring placed inside the installation ring, a filter screen fixedly installed inside the connecting ring, two installation grooves symmetrically opened on the inner wall of the installation ring, each of the two installation grooves having a clamp inside, two sliding rods symmetrically and movably inserted into the surface of the installation ring, each of the two sliding rods having a contact head fixedly installed at the ends away from each other, and the ends of the two sliding rods being fixedly connected to the two clamps respectively, each of the two sliding rods having a spring sleeved on the surface of the two sliding rods, each of the two springs being fixedly connected to the installation ring and the contact head respectively, the transmission component being drivenly connected to the installation ring, and the drive motor outputting power to the installation ring through the transmission component when it is running.

[0006] Preferably, the transmission assembly includes an upper sprocket and a positioning frame. The upper sprocket is fixedly installed at the output end of the drive motor. One side of the upper sprocket is rotatably connected to the filter tank via a shaft seat. The positioning frame is fixedly installed at the lower rear of the filter tank. Both ends of one side of the positioning frame are rotatably mounted with lower sprockets. A chain is meshed between the upper sprocket and the two lower sprockets.

[0007] Preferably, a shaft is fixedly installed on one side of each of the lower sprockets, and one end of each shaft extends into the interior of the filter tank and is fixedly installed with a drive bevel gear. The surfaces of the two shafts are rotatably connected to the filter tank through sealed bearings.

[0008] Preferably, the upper part of the surface of the driving bevel gear is meshed with a driven bevel gear, the bottom of the driven bevel gear is rotatably connected to the inner bottom of the filter tank, the top of the driven bevel gear is fixedly installed with a threaded rod, the top of the two threaded rods is rotatably connected to the bottom of the two transmission bars respectively, the lower part of the surface of the threaded rod is meshed with a threaded sleeve, the surface of the threaded sleeve is fixedly installed with a support rod, and the top of the two support rods is fixedly connected to the mounting ring.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When the filter screen is to be removed, the operator opens the movable cover and starts the drive motor to drive the upper sprocket to rotate along the shaft seat. When the upper sprocket rotates, it drives the two lower sprockets to rotate along the positioning frame through the chain. When the two lower sprockets rotate, they drive the two shafts to rotate inside the two sealed bearings. When the two shafts rotate, they drive the driven bevel gear to rotate through the active bevel gear. When the driven bevel gear rotates, it drives the threaded sleeve to move upward through the threaded rod. When the threaded sleeve moves upward, it pushes the mounting ring upward through the support rod.

[0010] When the mounting ring moves upward, it causes the receiving hopper and filter screen to move to the outside of the filter tank. Simultaneously, the mounting ring also causes the two contact heads to move upward along the two drive bars. Since the two drive bars are slanted strips, narrower at the top and wider at the bottom, the upward movement of the two contact heads, pushed by the elastic force of the two springs, causes them to move backward. This backward movement of the contact heads causes the two clamps to move away from the connecting ring via two sliding rods, thus releasing the clamping and fixing of the connecting ring. This allows the filter screen to be quickly removed for cleaning. This eliminates the need for operators to insert their hands into the device when disassembling the filter screen, preventing pesticide contamination of the operator's arms and ensuring the operator's health.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1 to 6 The present invention includes a filter tank 1, four support legs 3 fixedly and equidistantly installed at the bottom of the filter tank 1 in a ring, a movable cover 2 on the top of the filter tank 1, a support frame 4 fixedly installed on the upper rear part of the filter tank 1, a drive motor 5 fixedly installed on one side of the support frame 4, a transmission assembly on the output end of the drive motor 5, two transmission bars 6 symmetrically fixedly installed on the inner wall of the filter tank 1, an installation ring 7 inside the filter tank 1, a receiving hopper 8 fixedly installed on the top of the installation ring 7, a connecting ring 9 placed inside the installation ring 7, and a filter screen 10 fixedly installed inside the connecting ring 9. Two mounting grooves 11 are symmetrically opened on the inner wall of the mounting ring 7. Each mounting groove 11 is equipped with a clamp 12. Two sliding rods 15 are symmetrically and movably inserted into the surface of the mounting ring 7. A contact head 14 is fixedly installed at the far end of each sliding rod 15. The close end of each sliding rod 15 is fixedly connected to the two clamps 12. A spring 13 is sleeved on the surface of each sliding rod 15. Both ends of the two springs 13 are fixedly connected to the mounting ring 7 and the contact head 14, respectively. The transmission component is connected to the mounting ring 7. When the drive motor 5 is running, it outputs power to the mounting ring 7 through the transmission component.

[0022] To remove the filter screen 10, the operator opens the movable cover 2 and starts the drive motor 5 to drive the transmission component. When the transmission component is running, it pushes the mounting ring 7 upward. When the mounting ring 7 moves upward, it will drive the receiving hopper 8 and the filter screen 10 to the outside of the filter tank 1. At the same time, the mounting ring 7 will also drive the two contact heads 14 to move upward along the two transmission bars 6. Since the two transmission bars 6 are oblique bars that are narrow at the top and wide at the bottom, when the two contact heads 14 move upward, they will be driven by the elastic force of the two springs 13 to move backward. When the two contact heads 14 move backward, they will drive the two clamps 12 away from the connecting ring 9 through the two slide rods 15, thereby releasing the clamping and fixing of the connecting ring 9, and thus the filter screen 10 can be quickly removed for cleaning. This means that when the filter screen 10 is removed, the operator does not need to put their hands into the inside of the device, avoiding the operator's arms from getting contaminated with pesticides and ensuring the operator's health.

A shaft 20 is fixedly mounted on one side of each lower sprocket 19. One end of each shaft 20 extends into the interior of the filter tank 1 and is fixedly mounted with a drive bevel gear 22. The two shafts 20... All surfaces are rotatably connected to the filter tank 1 via sealed bearings 21; the upper part of the surface of the driving bevel gear 22 is meshed with the driven bevel gear 23, the bottom of the driven bevel gear 23 is rotatably connected to the inner bottom of the filter tank 1, the top of the driven bevel gear 23 is fixedly installed with a threaded rod 25, the top of the two threaded rods 25 is rotatably connected to the bottom of the two transmission bars 6 respectively, the lower part of the surface of the threaded rod 25 is meshed with a threaded sleeve 26, the surface of the threaded sleeve 26 is fixedly installed with a support rod 24, the top of the two support rods 24 is fixedly connected to the mounting ring 7.

[0024] The operator starts the drive motor 5, which drives the upper sprocket 16 to rotate along the shaft seat 17. When the upper sprocket 16 rotates, it drives the two lower sprockets 19 to rotate along the positioning frame 18 via the chain 27. When the two lower sprockets 19 rotate, they drive the two shafts 20 to rotate inside the two sealed bearings 21. When the two shafts 20 rotate, they drive the driven bevel gear 23 to rotate via the driving bevel gear 22. When the driven bevel gear 23 rotates, it drives the threaded sleeve 26 to move upward via the threaded rod 25. When the threaded sleeve 26 moves upward, it pushes the mounting ring 7 upward via the support rod 24.
