Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment and purification, in particular to a grille decontamination component and a grille decontamination device. Background Art

[0002] The screen cleaner is a mechanical device used to remove pollutants from fluids. It plays an important role in wastewater treatment and water purification. It uses a unique rake structure and is driven by a motor reducer to perform rotational motion. During operation, the rake captures and separates suspended solids in the fluid from the liquid surface. As the rake moves to the upper part of the equipment, the solid matter falls by gravity and is collected, while the rake continues to rotate. The whole process can be continuous or intermittent, with a high degree of automation and separation efficiency.

[0003] Most existing screen cleaners, such as those disclosed in Chinese Utility Model Publication No. CN220899759U, rely on a motor to drive the rotation of a rotary screen and rake teeth to salvage suspended matter from the water surface and purify the water. However, in these screen cleaners, the width of the rotary screen is fixed. When cleaning a wider water surface, multiple rotary screen machines need to be arranged in a sequential manner along the width of the water surface. These multiple rotary screen machines are independent of each other, meaning that multiple motors are required to separately drive the rotation of their corresponding rotary screens. This increases the number of drive sources and, in turn, the cost of sewage treatment. Furthermore, the increased number of drive sources makes the entire screen treatment device bulky and difficult to install.

[0004] Therefore, it is necessary to improve the grille decontamination device in the prior art. Utility Model Content

[0041] Reference Figures 1-6 As shown, the grille decontamination assembly of the utility model includes:

[0042] The dirt removal frame 1 includes side frames 11 that are arranged side by side and fixedly connected to each other, and the side frames 11 are provided with docking through holes 111 extending along the thickness direction of the side frames 11;

[0043] The grille assembly 2 is arranged between the side frames 11. The grille assembly 2 includes a closed-loop rotating grille 21 whose width direction is consistent with the distribution direction of the side frames 11. The outer side wall of the rotating grille 21 is provided with rake teeth 22 distributed along its circumference;

[0044] The transmission assembly is arranged on the inner side of the rotary grille 21 and is connected to the side frame 11 at both ends. The transmission assembly is provided with at least two transmission assemblies and is connected through the rotary grille 21. At least one transmission assembly is used to connect the output end of the rotating device 5 to drive the rotary grille 21 to rotate along its own circumferential direction; the transmission assembly includes a transmission shaft 3 axially parallel to the distribution direction of the side frame 11, a transmission wheel 31 coaxially arranged on the transmission shaft 3 and connected to the rotary grille 21, and a docking joint 4 coaxially arranged at both ends of the transmission shaft 3 and located on the inner side of the docking through hole 111. The side of the docking joint 4 away from the transmission shaft 3 is a docking surface 411, and the docking surface 411 is provided with matching convex columns 431 and concave holes 413. The axial centerline of the convex column 431, the axial centerline of the transmission shaft 3 and the axial centerline of the concave hole 413 are equally spaced and distributed in the same plane.

[0045] Specifically, the dirt removal frame 1 of the grille dirt removal assembly of the present invention has two side frames 11, which are parallelly arranged and have a plate-like structure with a waist-shaped outer edge. Circular through-hole-shaped docking holes 111 are provided at both ends of the side frames 11, and the inner side of the docking hole 111 is used to install the docking joint 4 at one end of the transmission shaft 3; the two side frames 11 are fixedly connected by a connecting frame 12 distributed side by side along the length direction of the two, and the connecting frame 12 is a U-shaped structure, and the two ends of the connecting frame 12 are respectively welded to the back of the two side frames 11.

[0046] The grille assembly 2 includes a rotating grille 21 that is arranged at equal intervals and distributed side by side along the distribution direction of the two side frames 11. The rotating grille 21 is waist-shaped, and the two ends of the rotating grille 21 are coaxial with the docking holes 111 at both ends of the side frames 11. L-shaped rake teeth 22 are provided on the circumferential outer edge of the rotating grille 21. The rake teeth 22 are evenly distributed at equal intervals along the circumference of the rotating grille 21. The grille assembly 2 also includes a synchronization bar 23. The length direction of the synchronization bar 23 is parallel to the distribution direction of the two side frames 11. The number of synchronization bars 23 is equal to the number of rake teeth 22 on the outer wall of a single rotating grille 21 and is fixedly connected to achieve synchronous movement of multiple rotating grilles 21.

[0047] There are two transmission components and they correspond one-to-one to the two docking through holes 111. Specifically, the transmission shaft 3 in the transmission component is coaxial with the docking through hole 111. Two transmission wheels 31 distributed along its axial direction are welded and fixed coaxially on the transmission shaft 3. The circumferential outer edge of the transmission wheel 31 is in contact with the inner side wall of the end of one of the rotary grids 21. The transmission wheel 31 is a synchronous wheel, and the end of the transmission shaft 3 is coaxially connected with a docking joint 4. The two opposite sides of the two docking joints 4 on the same transmission shaft 3 are docking surfaces 411. The docking surface 411 is provided with matching convex columns 431 and concave holes 413, and the axial center lines of the convex columns 431, the axial center lines of the transmission shaft 3 and the axial center lines of the concave holes 413 are equally spaced and distributed on the same plane.

[0048] After adopting the above structure, when it is necessary to clean a water surface with a width greater than or equal to twice the width of the grille dirt removal assembly of the utility model, two or more grille dirt removal assemblies are sequentially fitted and fixedly connected along their own width direction. At the same time, the protruding columns 431 of one of the two butt joints 4 opposite to the adjacent two grille dirt removal assemblies are inserted into the concave holes 413 of the other, and the protruding columns 431 of the rear pair of joints 4 are also inserted into the concave holes 413 of the front pair of joints 4. After splicing in this way, the dirt removal frames 1 of the adjacent two grille dirt removal assemblies are fixedly connected. After connection, it is only necessary to connect the output end of the rotating device 5 to one of the docking joints 4 located on the outside at any end position, so that the rotating device 5 drives the docking joint 4 and the transmission shaft 3 corresponding to the docking joint 4 to rotate, while the rotary grille 21 in the grille cleaning assembly rotates, driving the rake teeth 22 to rotate, and the debris on the water surface can be salvaged. At the same time, the docking joints 4 at the same axial position in the grille cleaning assembly at other positions rotate, and the transmission shaft 3 and the transmission wheel 31 rotate, which can drive the rotary grilles 21 at other positions to rotate and the rake teeth 22 to move.

[0049] Therefore, the grille dirt removal assembly of the present invention is conveniently spliced by connecting the convex column 431 and the concave hole 413 of the display screen on the docking joint 4. In the combination to form a grille dirt removal device for purifying water quality, only one rotating device 5 is required to simultaneously drive multiple rotary grilles 21 to rotate to achieve water cleaning and purification. In this way, by reducing the number of rotating devices 5, it is beneficial to reduce the cost of the grille dirt removal device, and the structure is more compact, which is convenient for installation and splicing.

[0050] A further improvement is that multiple protrusions 431 and recesses 413 are provided, and the protrusions 431 and recesses 413 are provided in a one-to-one correspondence. Specifically, there are four protrusions 431 and four recesses 413, and the four recesses 413 and four protrusions 431 are distributed in a ring with the axis of the docking joint 4 as the centerline and are spaced apart. With this structure, the number of protrusions 431 and recesses 413 is increased. When two grille cleaning assemblies are spliced, the multiple sets of plug-in matching recesses 413 and protrusions 431 ensure a stable transmission connection between the docking joint 4 and the drive shaft 3 at the same axis, which in turn helps to ensure a stable transmission connection of the rotary grille 21.

[0051] A further improvement is that the two ends of the transmission shaft 3 are fixedly connected with a disc 32 coaxially, the docking joint 4 includes an outer disc 41, an inner disc 42 and a screw 43, and the docking surface 411 is arranged on the side of the outer disc 41 facing away from the inner disc 42. The outer disc 41 and the inner disc 42 are detachably connected by the screw 43 to enclose an assembly cavity that is adapted to the disc 32 and coaxial with the transmission shaft 3. The outer disc 41 is provided with connecting through holes 412 distributed along its own circumference. The connecting through holes 412 include recessed holes 413 and assembly holes 414 arranged between the recessed holes 413 and threadedly connected to the inner wall and the screw 43. The boss 431 is connected to the screw 43 coaxially.

[0052] Specifically, in the present invention, the disc 32 is integrally connected to the end of the transmission shaft 3 coaxially. In the docking joint 4, the outer disc 41 is an outer barrel shape, which is sleeved on the outside of the disc 32 from the end of the transmission shaft 3. The inner disc 42 has two semicircular arcs. The outer disc 41 is provided with eight connecting through holes 412 distributed in a circular array, which are four recessed holes 413 and four assembly holes 414 distributed at intervals. The inner disc 42 is provided with four circular holes distributed in a circular array, which correspond one to one with the four recessed holes 413 and the four assembly holes 414. When an outer disc 41 and two inner discs 42 are spliced together, an assembly cavity adapted to the disc 32 is enclosed, and the outer disc 41 and the two inner discs 42 are threadedly connected by four screws 43 distributed in a circular array. The ends of the four screws 43 are fixedly connected with four protruding columns 431 coaxially, which are convenient for inserting into the inner sides of the four recessed holes 413 of the docking joint 4 of other grille dirt removal components. By adopting the above structure, the butt joint 4 is of split structure, which is convenient for splicing and assembling, and ensures that the transmission shaft 3 and the butt joint 4 are coaxial.

[0053] A further improvement is that the butt joint 4 is rotationally coupled to the transmission shaft 3 and is positionally connected, with the axis of relative rotation between the butt joint 4 and the transmission shaft 3 coinciding with the axis of the transmission shaft 3. By adopting the above structure, the butt joint 4 can rotate relative to the transmission shaft 3 at a certain angle. When the two reach a certain relative rotation angle, the butt joint 4 and the transmission shaft 3 rotate synchronously.

[0054] Specifically, a first limiting plate 331 is provided on the circumferential outer edge of the transmission shaft 3 , and a second limiting plate 415 is provided on the docking joint 4 . The first limiting plate 331 and the second limiting plate 415 are spaced apart along the circumference of the transmission shaft 3 .

[0055] To be more specific, the side of the disc 32 away from the transmission shaft 3 is integrally connected to the convex disc 33 coaxially, and the outer periphery of the convex disc 33 is distributed with four first limiting plates 331 in an annular array, while the inner side wall of the outer disc 41 is distributed with four second limiting plates 415 in an annular array.

[0056] After the butt joint 4 is assembled on the transmission shaft 3, in the initial state, the four first limit plates 331 and the four second limit plates 415 are spaced apart, allowing the butt joint 4 to rotate a certain angle about the axis of the transmission shaft 3 until the four second limit plates 415 simultaneously abut against the four second limit plates 415. When the outer disk 41 on the butt joint 4 rotates, the second limit plates 415 act on the first limit plates 331, causing the first limit plates 331 and the disk 32 to rotate, thereby driving the transmission shaft 3 to rotate. In this way, a relative rotational connection and a limiting connection are achieved between the butt joint 4 and the transmission shaft 3. Four first limit plates 331 and four second limit plates 415 are provided, ensuring stable circumferential transmission between the butt joint 4 and the transmission shaft 3 and ensuring uniform and consistent force distribution.

[0057] A further improvement is that the docking joint 4 further includes a bearing 44 sleeved around the outer and inner discs 41 and 42. The outer ring of the bearing 44 is fixedly connected to the circumferential inner wall of the docking hole 111, while the inner ring is fixedly connected to the circumferential outer edge of the outer disc 41. This structure ensures the stable rotation of the outer and inner discs 41 and 42, and the transmission shaft 3, relative to the side frame 11.

[0058] The utility model also discloses a grille decontamination device, comprising:

[0059] The dirt removal mechanism includes the above-mentioned grille dirt removal assembly, which is fixedly connected along the distribution direction of its own side frame 11. In the two adjacent grille dirt removal assemblies, the two opposite docking joints 4 are plugged into and matched with the protruding column 431 of one docking joint 4 and the concave hole 413 of the other docking joint 4.

[0060] The rotating device 5 includes a rotating motor 51, and the output end of the rotating motor 51 is drivingly connected to one of the docking joints 4 in one of the end position decontamination components;

[0061] The collecting assembly 6 includes a collecting trough 61 with an open top and a vibrator 62 arranged at the bottom of the collecting trough 61. The collecting trough 61 is arranged to be inclined downward and is located directly below the top of the dirt removal mechanism. The projection of the top of the dirt removal mechanism on the horizontal plane is located within the projection of the notch of the collecting trough 61 on the horizontal plane to receive debris that falls from the rake teeth 22 that rotate to the top of the rotary grille 21.

[0062] Specifically, it also includes two fixing frames 9 and several connecting components 7. The dirt removal mechanism is arranged between the two fixing frames 9. The connecting component 7 is used to fix the two adjacent grille dirt removal components, the grille dirt removal component at the end position and the fixing frame 9. The fixing frame 9 is fixed on the ground. The connecting component 7 includes a threaded bolt 71 and a nut 72. The bolt 71 is passed through the connecting frame 12 and is threadedly connected to the nut 72, so as to connect the two adjacent grille dirt removal components and the dirt removal frame 1 and the fixing frame 9 in the grille dirt removal assembly at the end position.

[0063] The rotating device 5 is arranged on the grille cleaning component at one end. Specifically, the rotating device 5 includes a rotating motor 51. The casing of the rotating motor 51 is welded and fixed to the side frame 11 through a mounting frame 511. The mounting frame 511 is a downward protective cover-like structure for protecting the rotating motor 51 and preventing it from being corroded by rainwater. The output shaft of the rotating motor 51 is fixedly connected to the inner sleeve 52 opposite to it coaxially. The inner sleeve 52 is a square tube. The four side walls of the inner sleeve 52 are provided with a first slider 521. The outer sealing sleeve of the inner sleeve 52 is provided with an outer sleeve 53. The four side walls of the outer sleeve 53 are provided with a sliding fit with the first slider 521 and parallel to the rotating motor 5. A compression spring 56 is provided between the first sliding opening 531 extending axially from the output shaft and the inner cavity enclosed by the inner sleeve 52 and the outer sleeve 53. The two ends of the compression spring 56 are connected to the inner sleeve 52 and the outer sleeve 53, respectively. A protective cover 55 is fixedly provided on the outer sleeve 53, covering the first sliding opening 531, to prevent moisture from entering the inner and outer sleeves 52 and 53 and corroding the compression spring 56. The end of the outer sleeve 53 away from the inner sleeve 52 is fixedly connected to the docking plate 54 coaxially. The docking plate 54 has four plug posts 542 and four sockets 541 arranged in a circular array at intervals. The plug posts 542 are adapted to fit into the recessed holes 413, and the sockets 541 are adapted to fit into the protruding posts 431.

[0064] After adopting the above structure, the rotating motor 51 is fixed to the side frame 11 of the grille cleaning assembly at the end position through the mounting frame 511, the outer sleeve 53 is moved closer to the inner sleeve 52, and the docking head 4 is rotated so that the plug post 542 on the docking plate 54 is aligned with the recessed hole 413, and the plug hole 541 is aligned with the protruding column 431. Then, the outer sleeve 53 is loosened, and under the elastic force of the compression spring 56, the compression spring 56 pushes the outer sleeve 53 and the docking plate 54 to move closer to the side frame 11, so that the plug post 542 is inserted into the recessed hole 413. When the protrusion 431 is relatively inserted into the insertion hole 541, in this connection state, the rotary motor 51 is started, which can drive the docking plate 54 to rotate, so that the docking head 4 drives the transmission wheel 31 to rotate through the transmission shaft 3, and then drives the rotary grille 21 in each grille cleaning assembly to rotate, so that the rake teeth 22 move to salvage the suspended debris on the water surface. After rotating to the top of the rotary grille 21, the rake teeth 22 move downward, and the debris falls into the collection tank 61 under the influence of gravity. Under the action of the vibrator 62, the debris is discharged from the collection tank 61.

[0065] In the grille dirt removal device, adjacent grille dirt removal components are plugged in and matched with each other through matching protrusions 431 and recessed holes 413. Therefore, only one rotating device 5 is required to drive the rotary grilles 21 of multiple grille dirt removal components to rotate, reducing the number of rotating devices 5, which not only reduces costs but also makes the structure more compact and convenient to install.

[0066] A further improvement is that the collecting groove 61 includes an inner groove 611 and an outer groove 612 which are consistent in length direction and are slidably connected to each other, and the outer wall of the inner groove 611 fits with the inner wall of the outer groove 612.

[0067] Specifically, two outer grooves 612 and two inner grooves 611 are provided. Both inner grooves 611 are tilted downward and arranged in mirror-image symmetry. The ends of the two inner grooves 611 are fixedly connected as one body. The inner bottom walls of both the outer groove 612 and the inner groove 611 are provided with water-permeable holes 615 to facilitate drainage. A second slider 613 is provided on the inner sidewall of the outer groove 612, and a second sliding opening 614 is provided on the sidewall of the inner groove 611 along its length. The second slider 613 and the second sliding opening 614 are slidably connected to achieve relative sliding connection between the outer groove 612 and the inner groove 611. A support foot is provided below the end of the outer groove 611 away from the inner groove 612 for fixing to the ground.

[0068] With the above structure, it is convenient to adjust the relative positions of the two outer grooves 612 according to the specific width of the dirt removal mechanism, and fix the supporting feet on the ground, thereby adjusting and fixing the length of the collection groove 61.

[0069] The two side frames 11 at the end positions are fixedly connected with elastic sealing plates 8, which are rubber plates. When in use, the sealing plates 8 can undergo elastic deformation so that the width of the side of the two sealing plates 8 away from the decontamination mechanism is consistent with the width of the water surface to be treated, thereby preventing suspended matter on the water surface from passing through the gap outside the side frames 11, thereby ensuring the water purification effect.

[0070] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods.
