Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to an anti-clogging cleaning device for a reaction vessel used in pesticide production. Background Technology

[0002] In the pesticide production process, the reaction vessel is a key piece of equipment. Its interior is prone to residual materials such as crystals and resinous deposits. If not cleaned in time, it will cause blockages and affect the continuity of production.

[0003] Existing anti-clogging cleaning devices for reactors mostly employ high-pressure water jet automatic cleaning systems. These systems use high-pressure pumps to pressurize water, which is then channeled through specialized nozzles to form a high-speed water jet that breaks down and removes scale from the reactor's inner wall. However, current three-dimensional rotating nozzles often extend into the reactor via telescopic rods. Due to the large distance between the telescopic rods and the reactor inlet wall, these rods tend to shake violently during operation, resulting in poor stability.

[0004] To address the aforementioned problems, this utility model document proposes an anti-clogging cleaning device for a reaction vessel used in pesticide production. Utility Model Content

[0005] This invention provides an anti-clogging cleaning device for a reaction vessel used in pesticide production, which solves the shortcomings of the existing technology where the three-dimensional rotating nozzle is inserted into the vessel through a telescopic rod. Due to the large distance between the telescopic rod and the inner wall of the vessel inlet, the nozzle is prone to violent shaking during use, resulting in poor stability.

[0006] This utility model provides the following technical solution:

[0007] A clog-prevention cleaning device for a pesticide production reactor includes:

[0008] A vertical frame is provided, with a base plate welded and fixed to the bottom of the vertical frame. Foot brake type universal wheels are fixedly installed at the four corners of the bottom of the base plate. A vertically movable mounting plate is provided on the open side of the vertical frame. Two triangular reinforcing frames are symmetrically welded and fixed to the bottom of the mounting plate. A booster water pump is fixedly installed on the top of the mounting plate.

[0009] The input end of the booster pump is connected to an external water source via a hose, and the output end of the booster pump is connected to a conveying steel pipe that extends into the interior of the reactor. A three-dimensional rotating nozzle is installed at the bottom end of the conveying steel pipe, and a fixing plate is fitted on the conveying steel pipe to improve its vertical movement stability. The fixing plate is located above the three-dimensional rotating nozzle.

[0010] In one possible design, the same threaded screw is rotatably mounted on both ends of the inner wall of the vertical frame via bearings. A matching screw seat is threaded onto the threaded screw. One side of the screw seat passes through the side opening of the vertical frame and is fixedly connected to one side of the mounting plate. A drive motor for driving the threaded screw to rotate is fixedly mounted on the top of the vertical frame. The output shaft of the drive motor passes through the inner wall of the vertical frame and is fixedly connected to the top end of the threaded screw.

[0011] In one possible design, sliders for improving the stability of movement are fixedly provided on both sides of the lead screw seat, and a groove for sliding connection of the corresponding slider is provided on the inner wall of the vertical frame. First pulleys are rotatably installed on both sides of the slider, and the center of both ends of the first pulleys are rotatably connected to the inner wall of the mounting seat fixed on the slider through bearings. The first pulleys are in contact with the vertical wall of the groove.

[0012] In one possible design, a row of second pulleys is rotatably mounted on one side of the triangular reinforcement frame. The center of both ends of the second pulleys is rotatably connected to the inner wall of the mounting base fixed on the triangular reinforcement frame via bearings. The second pulleys are in contact with the outer wall of the vertical frame.

[0013] In one possible design, two U-shaped guide wheels are symmetrically and rotatably mounted on the top of the fixed disk. The center of each end of the U-shaped guide wheel is rotatably connected to the inner wall of the mounting seat fixed on the fixed disk via bearings. The U-shaped guide wheels are in contact with the outer wall of the conveying steel pipe. The conveying steel pipe passes through the gap between the two U-shaped guide wheels and through the through hole in the center of the fixed disk.

[0014] In one possible design, the fixed plate has multiple reserved holes arranged in a ring array, each containing a corresponding bolt. The end of the bolt passes through a hole aligned with the connecting flange at the top of the reactor and is threaded with a corresponding nut.

[0015] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0016] The working principle and usage process of this technical solution are as follows:

[0017] When in use, shut down the feed, discharge, and insulation systems of the reactor and disconnect the power. Use the foot-brake casters to move the cleaning device to a suitable position next to the reactor, and fix the foot brakes to lock the position. Then, fasten the fixing plate to the connecting flange on the top of the reactor with bolts and nuts. After starting the drive motor, the mounting plate is driven to move vertically along the vertical frame through the threaded transmission between the threaded screw and the screw seat. The sliders on both sides of the screw seat roll in the groove through the first pulley to reduce friction and prevent deviation. The second pulley on the triangular reinforcement frame is in contact with the outer wall of the vertical frame to further suppress the lateral sway of the mounting plate. The mounting plate drives the booster water pump and the conveying steel pipe to move synchronously, so that the three-dimensional rotating nozzle is accurately lowered to the specified cleaning height inside the reactor.

[0018] During cleaning, a booster pump draws external water through a hose, pressurizes the water, and delivers it to the three-dimensional rotating nozzle via a conveying steel pipe. Driven by high-pressure water, the three-dimensional rotating nozzle rotates automatically, forming a high-speed water jet that impacts and peels off residual materials such as crystals and resinous deposits from the inner wall of the reactor. The fixed plate on the outside of the conveying steel pipe restricts its radial displacement through two U-shaped guide wheels, preventing the steel pipe from shaking violently due to the reaction force of the high-pressure water and ensuring stable operation of the nozzle. During the cleaning process, the operator can observe the cleaning status through the observation window on the top of the reactor. After cleaning, the bolts of the fixed plate are loosened, the drive motor rotates in the opposite direction, and the mounting plate is lifted to the initial height through the threaded screw. The three-dimensional rotating nozzle then exits the reactor, and the device is moved to the next cleaning target or storage location.

[0019] This utility model has the following beneficial effects:

[0020] In this invention, the fixed plate is securely connected to the top flange of the reactor with bolts and nuts, providing a stable support point for the conveying steel pipe. Two U-shaped guide wheels symmetrically rotated on the top of the fixed plate are in dynamic contact with the outer wall of the conveying steel pipe, guiding and stabilizing the vertical movement of the conveying steel pipe, further improving the stability of the conveying steel pipe and the bottom three-dimensional rotating nozzle.

[0021] In this invention, the sliders on both sides of the lead screw seat slide in the grooves on the inner wall of the vertical frame. The first pulleys on both sides of the sliders contact the vertical wall of the grooves, reducing the friction between the sliders and the grooves, making the sliders move more smoothly, and improving the stability of the sliders' movement, thereby enhancing the stability of the mounting plate's movement.

[0022] In this utility model, two triangular reinforcing frames are symmetrically welded and fixed to the bottom of the mounting plate. A row of second pulleys rotatably mounted on the frame contacts the outer wall of the vertical frame, which further stabilizes and guides the movement of the mounting plate, reduces the shaking of the mounting plate during vertical movement, and enables the booster pump and conveying steel pipe and other components to work stably.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0031] In one embodiment:

[0032] Please refer to Figure 1-4 A cleaning apparatus, comprising:

[0033] The vertical frame 1 has a fixed base plate 2 welded to its bottom. Foot brake type universal wheels 3 are fixedly installed at the four corners of the bottom of the base plate 2. The foot brake type universal wheels 3 can be used to easily move the entire cleaning device to a suitable position next to the reactor, and the foot brakes can be fixed to lock the position of the device.

[0034] The same threaded screw 4 is rotatably mounted on both ends of the inner wall of the vertical frame 1 via bearings. The threaded screw 4 is threadedly connected to a matching screw seat 5. One side of the screw seat 5 passes through the side opening of the vertical frame 1 and is fixedly connected to one side of the mounting plate 10. The top of the vertical frame 1 is fixedly mounted with a drive motor 6. The output shaft of the drive motor 6 passes through the inner wall of the vertical frame 1 and is fixedly connected to the top of the threaded screw 4. After the drive motor 6 is started, the drive motor 6 drives the threaded screw 4 to rotate. Through the threaded transmission between the threaded screw 4 and the screw seat 5, the mounting plate 10 is driven to move vertically along the vertical frame 1.

[0035] Slider 7 is fixedly installed on both sides of the lead screw seat 5. A sliding groove 8 is provided on the inner wall of the vertical frame 1 for sliding connection of the corresponding slider 7. First pulleys 9 are rotatably installed on both sides of the slider 7. The center of both ends of the first pulleys 9 are rotatably connected to the inner wall of the mounting seat fixed on the slider 7 through bearings. The first pulleys 9 are in contact with the vertical wall of the sliding groove 8. During the movement of the mounting plate 10, the sliders 7 on both sides of the lead screw seat 5 roll in the sliding groove 8 through the first pulleys 9, which reduces the friction between the sliders 7 and the sliding groove 8, making the sliders 7 move more smoothly and preventing the sliders 7 from deviating. This improves the stability of the movement of the sliders 7 and enhances the stability of the movement of the mounting plate 10.

[0036] Two triangular reinforcing frames 11 are symmetrically welded and fixed to the bottom of the mounting plate 10. A row of second pulleys 12 is rotatably installed on one side of the triangular reinforcing frame 11. The two ends of the second pulleys 12 are rotatably connected to the inner wall of the mounting seat fixed on the triangular reinforcing frame 11 through bearings. The second pulleys 12 are in contact with the outer wall of the vertical frame 1. When the mounting plate 10 moves, the second pulleys 12 on the triangular reinforcing frame 11 are in contact with the outer wall of the vertical frame 1, further suppressing the lateral sway of the mounting plate 10 and reducing the sway of the mounting plate 10 during vertical movement.

[0037] A booster pump 13 is fixedly installed on the top of the mounting plate 10. The input end of the booster pump 13 is connected to an external water source via a hose, and the output end is connected to a conveying steel pipe 14. The conveying steel pipe 14 extends into the reactor, and a three-dimensional rotating nozzle 15 is threadedly installed at the bottom end of the conveying steel pipe 14. The rotational power of the three-dimensional rotating nozzle 15 mainly comes from the recoil force of the high-pressure water jet and the hydraulic torque formed by the nozzle offset. When the high-pressure water is sprayed out through the nozzle, due to the eccentricity of the two nozzles along the axial direction, the water flow will generate a reaction force on the nozzle, causing the pinion to rotate around the horizontal axis. The transmission mechanism that forms the three-dimensional rotation generally uses a pair of mutually perpendicular bevel gears. The pinion passes through the large gear... Under the meshing action of the wheel, the rotating sealing component is driven to rotate along the vertical axis. At the same time, the passive bevel gear drives the impeller to rotate in the opposite direction through the gear train, realizing the revolution of the nozzle body and the rotation of the nozzle itself, forming a synchronous three-dimensional rotation. One component of the water jet is sprayed onto the impeller through the fixed nozzle, forming a resistance torque. The rotation of the impeller is fed back to the bevel gear, which forms a deceleration effect, ensuring that the jet does not atomize, and achieving the purpose of powerful cleaning and delamination. During use, the jet trajectory of the three-dimensional rotating nozzle 15 forms a spherical envelope surface, which can achieve 360° cleaning without dead angles. By adjusting the relative position of the two nozzles, that is, adjusting the rotational torque formed by the jet, the speed can be adjusted within a certain range.

[0038] A fixed plate 16 is fitted onto the conveying steel pipe 14. The fixed plate 16 is located above the three-dimensional rotating nozzle 15. Two U-shaped guide wheels 17 are symmetrically and rotatably mounted on the top of the fixed plate 16. The two ends of the U-shaped guide wheels 17 are rotatably connected to the inner wall of the mounting seat fixed on the fixed plate 16 through bearings. The U-shaped guide wheels 17 are in contact with the outer wall of the conveying steel pipe 14. The conveying steel pipe 14 passes through the gap between the two U-shaped guide wheels 17 and through the through hole in the center of the fixed plate 16. Multiple reserved holes are arranged in a ring array on the fixed plate 16. Each reserved hole is equipped with a corresponding bolt 18. The end of the bolt 18 passes through the hole of the fixed plate 16 that is aligned with the connecting flange at the top of the reactor and is then threaded with the corresponding nut 19 to fasten the fixed plate 16 to the connecting flange at the top of the reactor, providing a stable support point for the conveying steel pipe 14.

[0039] In practical use, first shut down the feed, discharge and heat preservation systems of the reactor and disconnect the power. Use the foot brake caster 3 to move the cleaning device to a suitable position next to the reactor and fix the foot brake to lock the position. Then, fasten the fixing plate 16 to the connecting flange on the top of the reactor with bolts 18 and nuts 19. After starting the drive motor 6, the drive motor 6 drives the threaded screw 4 to rotate. Through the thread transmission between the threaded screw 4 and the screw seat 5, the mounting plate 10 is driven to move vertically along the vertical frame 1. The mounting plate 10 drives the booster water pump 13 and the conveying steel pipe 14 to move synchronously, so that the three-dimensional rotating nozzle 15 is accurately lowered to the specified cleaning height in the reactor. During the movement of the mounting plate 10, the sliders 7 on both sides of the screw seat 5 roll in the groove 8 through the first pulley 9 to reduce friction and prevent deviation. At the same time, the second pulley 12 on the triangular reinforcement frame 11 is in contact with the outer wall of the vertical frame 1 to further suppress the lateral sway of the mounting plate 10.

[0040] During cleaning, the booster water pump 13 draws external water through a hose, pressurizes the water, and delivers it to the three-dimensional rotating nozzle 15 via the conveying steel pipe 14. The three-dimensional rotating nozzle 15 rotates automatically under the drive of high-pressure water, forming a high-speed water jet with multiple angles and full coverage. This jet impacts and peels off residual materials such as crystals and resinous wall-hanging materials from the inner wall of the reactor. The fixed plate 16 on the outside of the conveying steel pipe 14 restricts its radial displacement through two U-shaped guide wheels 17 to prevent the steel pipe from shaking violently due to the reaction force of the high-pressure water, ensuring stable operation of the nozzle. During the cleaning process, the operator can observe the cleaning situation through the observation window on the top of the reactor. After cleaning, the bolts 18 of the fixed plate 16 are loosened, the drive motor 6 rotates in the opposite direction, and the mounting plate 10 is lifted to the initial height through the threaded screw 4. The three-dimensional rotating nozzle 15 is then removed from the reactor, and the device is moved to the next cleaning target or storage location.

[0041] This application can be used for cleaning reaction vessels used in pesticide production, and can also be used in other fields applicable to this application.

[0044] Please refer to Figure 1 A soft protective cover made of canvas is installed on the inner wall of the side opening of the vertical frame 1 to reduce the impact of dust on the threaded screw 4.

Those skilled in the art can make any selections according to their needs or convenience.
