Description

Technical Field

[0001] This invention relates to the field of chemical dosing and mixing devices, specifically to a chemical dosing and mixing device for treating sediment pollution based on intelligent control. Background Technology

[0002] Currently, the main methods used for sediment remediation are in-situ treatment and ex-situ treatment. In-situ treatment technology treats sludge on-site, avoiding the high costs and secondary pollution associated with sludge transfer, while also preventing the loss of sediment from reservoirs. Existing in-situ treatment technologies mainly involve adding sediment amendments to the sediment. These amendments oxidize and remove reducing substances in the water, and degrade or absorb elements such as nitrogen and phosphorus, thereby solving the problem of sediment pollution.

[0003] Before adding the amendment agent to the reservoir, the agent needs to be prepared. This requires a dosing and mixing device for sediment pollution control to mix the agent and add it to the reservoir. Existing dosing and mixing devices mix the agent by rotating the stirring blades. However, the cylinder used to carry the agent is usually just placed on a support frame. When the agent is stirred and rotated, the cylinder will shake. Generally, the weight of the cylinder and the agent is used to avoid this shaking. However, the larger the amount of agent, the greater the force generated by the rotation, which cannot fundamentally solve the shaking problem. In addition, the existing stirring blades are fixed to the rotating shaft with bolts. If replacement is needed, the operation will be relatively troublesome. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a dosing and mixing device for sediment pollution treatment based on intelligent control, which solves the problems of shaking during the mixing of chemicals and the inconvenience of replacing the mixing blades in existing dosing and mixing devices for sediment pollution treatment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dosing and stirring device for treating sediment pollution based on intelligent control, comprising a supporting base, a supporting frame, a chemical cartridge, and a stirring assembly that operates under intelligent control. The supporting base has a supporting ring fixed in the middle position by multiple supporting rods. An anti-sway mechanism is provided inside the supporting ring to prevent the chemical cartridge from shaking. The anti-sway mechanism is installed in the supporting ring by multiple shock-absorbing components, which provide shock absorption. The anti-sway mechanism includes a supporting block with an annular groove inside. A cross groove is formed in the middle of the supporting block. Four racks are slidably connected to the inner surface of the cross groove. Four transmission gears are rotatably connected at equal intervals to the bottom of the inner wall of the annular groove. An annular gear is slidably connected to the inner surface of the annular groove. The annular gear meshes with all four transmission gears, and the four racks mesh with corresponding transmission gears.

[0006] Preferably, a drive motor is fixedly connected to the bottom of the support block, the output end of the drive motor passes through the support block and extends into the interior of the annular groove, and a drive gear is fixedly connected to the output end of the drive motor, the drive gear meshing with the annular gear for transmission.

[0007] Preferably, each of the four racks is fixedly connected to a fixing block at its top, the fixing block passing through the supporting round block and extending above the supporting round block, and each of the four fixing blocks is fixedly connected to an arc-shaped plate at its top.

[0008] Preferably, the shock absorption component includes multiple arc-shaped grooves equidistantly formed on the inner surface of the supporting ring, and multiple connecting blocks are fixedly connected at equal intervals to the annular surface of the supporting ring, with the multiple connecting blocks slidably connected to the corresponding arc-shaped grooves.

[0009] Preferably, a damper is rotatably connected to the inner wall of the arc-shaped groove, the output end of the damper is rotatably connected to one side of the connecting block, and a buffer spring is sleeved on the surface of the damper, with the two ends of the buffer spring contacting the inner wall of the arc-shaped groove and the side of the connecting block, respectively.

[0010] Preferably, the stirring assembly includes an input motor, a rotating shaft, and stirring blades. The stirring blades are mounted on the rotating shaft via a mounting assembly. The mounting assembly includes a mounting groove and a mounting rod at the bottom of the rotating shaft. A groove is formed at the top of the mounting rod. A circular plate is slidably connected to the inner surface of the groove. A first return spring is fixedly connected to the bottom of the circular plate. The other end of the first return spring is fixedly connected to the bottom of the inner wall of the groove.

[0011] Preferably, the mounting rod has a limiting groove on both the front and back sides, and the inner wall of the mounting groove has a limiting post on both the front and back sides that cooperates with the limiting groove. The top edge of the circular plate also has a slot.

[0012] Preferably, two L-shaped rods are slidably connected to the left and right sides of the rotating shaft via sliding grooves. One end of the two L-shaped rods bends downward and extends into the mounting groove. The other end of the two L-shaped rods is fixedly connected to a toggle ring. A second return spring is fixedly connected between the bottom of the L-shaped rod and the bottom of the inner wall of the sliding groove. Beneficial effects

[0013] This invention provides a chemical dosing and mixing device for treating sediment pollution based on intelligent control. Compared with the prior art, it has the following advantages:

[0014] 1. This intelligent control-based dosing and mixing device for treating sediment pollution uses an anti-sway mechanism on the support frame to clamp and fix the dosing cartridge, preventing it from shaking due to centrifugal force generated by dosing and mixing. The clamping operation of the cartridge is convenient and can fix cartridges of different sizes, improving the ease of use of the device.

[0015] 2. This intelligent control-based dosing and mixing device for treating sediment pollution absorbs the force generated during the mixing of chemicals by setting shock-absorbing components around the support block, thus preventing the entire support frame from shifting due to excessive force.

[0016] 3. This intelligent control-based dosing and mixing device for treating sediment pollution allows for the simple and quick installation of the mixing blades by mounting the mixing blades onto the rotating shaft using an installation component. When installing the mixing blades, the installation component only needs to be pressed in and rotated once, thus enabling the mixing blades to be installed quickly and easily.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] This intelligent control-based dosing and mixing device for sediment pollution treatment offers three technical solutions:

[0029] like Figure 1-5The first embodiment is shown: it includes a support base 1, a support frame 2, a cartridge 3, and a stirring assembly 4. A pressure pump, a delivery pipe, and a control box are installed on the support frame 2. The control box contains a controller that controls the start and stop of the entire device and intelligently controls the dosage. A support ring 11 located in the middle is fixed inside the upper support base 1 by multiple support rods 12. An anti-sway mechanism 5 is installed inside the support ring 11 to prevent the cartridge 3 from shaking. The anti-sway mechanism 5 is installed in the support ring 11 by multiple shock-absorbing components 6, and the shock-absorbing components 6 provide shock absorption. The anti-sway mechanism 5 includes a support block 51, with an annular groove 52 inside the support block 51 and a cross groove 53 in the middle of the support block 51. The inner surface of the cross groove 53 slides. Four racks 54 are connected. Four transmission gears 55 are equidistantly rotatably connected to the bottom of the inner wall of the annular groove 52. An annular gear 56 is slidably connected to the inner surface of the annular groove 52. The annular gear 56 meshes with the four transmission gears 55 for transmission. The four racks 54 mesh with the corresponding transmission gears 55 for transmission. A drive motor 57 is fixedly connected to the bottom of the support block 51. The output end of the drive motor 57 passes through the support block 51 and extends into the interior of the annular groove 52. A drive gear 58 is fixedly connected to the output end of the drive motor 57. The drive gear 58 meshes with the annular gear 56 for transmission. A fixing block is fixedly connected to the top of each of the four racks 54. The fixing block passes through the support block 51 and extends above the support block 51. An arc-shaped plate 59 is fixedly connected to the top of each of the four fixing blocks.

[0030] By using the anti-sway mechanism installed on the support base 2 to clamp and fix the cartridge 3, the position of the cartridge 3 is fixed when the medicine is stirred, thereby preventing the cartridge 3 from shaking due to the centrifugal force generated by stirring. Moreover, the clamping operation of the cartridge 3 is convenient and can fix cartridges 3 of different sizes, improving the convenience of using the device.

[0031] like Figure 2 and 3 The second embodiment is shown. The main difference between the second and first embodiments is that the shock-absorbing component 6 includes multiple arc-shaped grooves 61 that are equally spaced on the inner surface of the supporting ring 11. Multiple connecting blocks 62 are fixedly connected at equal intervals on the annular surface of the supporting block 51. The multiple connecting blocks 62 are slidably connected to the arc-shaped grooves 61 at corresponding positions. A damper 63 is rotatably connected to the inner wall of the arc-shaped groove 61. The output end of the damper 63 is rotatably connected to one side of the connecting block 62. A buffer spring 64 is sleeved on the surface of the damper 63. The two ends of the buffer spring 64 are in contact with the inner wall of the arc-shaped groove 61 and the side of the connecting block 62, respectively.

[0032] By setting shock-absorbing components 6 around the support block 51, the force generated during the stirring of the medicine is absorbed, thus avoiding the problem of the entire support base 2 shifting position due to excessive force.

[0033] like Figure 6-9 The third embodiment is shown, and its main difference from the second embodiment is that the stirring assembly 4 includes an input motor, a rotating shaft 7, and stirring blades. The stirring blades are mounted on the rotating shaft 7 via a mounting assembly 8. The mounting assembly 8 includes a mounting groove 81 at the bottom of the rotating shaft 7 and a mounting rod 82. A groove 83 is formed at the top of the mounting rod 82. A circular plate 84 is slidably connected to the inner surface of the groove 83. A first return spring 85 is fixedly connected to the bottom of the circular plate 84. The other end of the first return spring 85 is fixedly connected to the bottom of the inner wall of the groove 83. Limiting grooves 86 are provided on both the front and back of the rod 82. Limiting posts 87 that cooperate with the limiting grooves 86 are provided on both the front and back of the inner wall of the mounting groove 81. A slot 811 is also provided at the top edge of the circular plate 84. Two L-shaped rods 88 are slidably connected to the left and right sides of the rotating shaft 7 through the sliding groove. One end of the two L-shaped rods 88 is bent downward and extends into the mounting groove 81. The other end of the two L-shaped rods 88 is fixedly connected to a toggle ring 89. A second return spring 810 is fixedly connected between the bottom of the L-shaped rod 88 and the bottom of the inner wall of the sliding groove.

[0034] The stirring blade is installed onto the rotating shaft 7 by means of the mounting component 8. When installing the stirring blade, the mounting component 8 only needs to be pressed in and rotated once, so that the stirring blade can be installed simply and quickly.

[0035] During installation, the cartridge 3 is placed on top of the supporting block 51. The drive motor 57 is started, driving the drive gear 58 to rotate. The drive gear 58 rotates and transmits power to the ring gear 56. The ring gear 56 rotates and transmits power to the transmission gear 55. The transmission gear 55 rotates, causing the rack 54 to move. The rack 54 moves and drives the arc plate 59 to move closer to the outside of the cartridge 3, clamping it to the outside of the cartridge 3. At this point, the installation of the cartridge 3 is complete. When the stirring assembly 4 works and stirs the medicine in the cartridge 3, the generated force is first transmitted to the supporting block 51, causing the supporting block 51 to sway. This force is then transmitted to the connecting block 62, causing the buffer spring 64 to be compressed and the damper 63 to absorb the transmitted force. In addition, when installing the stirring blade, the stirring... The blade is fitted to the bottom of the rotating shaft 7, and the mounting rod 82 is installed into the mounting groove 81. The mounting rod 82 moves into the mounting groove 81, and the limiting post 87 enters the vertical part of the limiting groove 86. After reaching the bottom, the mounting rod 82 is rotated, so that the limiting post 87 enters the inclined part of the limiting groove 86, thereby causing the mounting rod 82 to move upward and press the stirring blade. In addition, when the limiting post 87 enters the end of the inclined part of the limiting groove 86, the limiting post 87 enters the slot 811 on the circular plate 84, thereby limiting the entire mounting rod 82 and preventing rotation. When disassembling, the ring 89 is pushed down so that the L-shaped rod 88 contacts the circular plate 84, causing the slot 811 to disengage from the limiting post 87. At this time, the mounting rod 82 is rotated and pulled out to complete the disassembly of the stirring blade.
