[0002] There are many types of automatic garbage intercepting mechanical screens in the field of sewage treatment, and the structures include rotary type and internal entry type. There are also many forms of intercepting garbage in sewage, such as bar structure, rake tooth structure, and mesh structure. Among the many garbage intercepting equipment, the internal entry mesh plate type mechanical screen has many advantages and is widely used due to its large processing capacity, large slag discharge, and no slag leakage at the rear end of the rear screen. However, it also has its shortcomings: the mesh of the internal entry mesh plate type mechanical screen is a punched structure, and fibrous garbage passes through multiple holes at the same time, easily forming entanglements and difficult to fall off, causing the mesh plate to be blocked, seriously affecting the equipment processing capacity. In order to solve the problem of mesh blockage, sufficient flushing water is required to ensure the mesh plate regeneration capacity. However, a large amount of flushing water increases water consumption, which increases the burden on users. At the same time, the flushing water needs to be treated and the treatment process needs to be increased. Utility Model Content

[0023] like Figures 1 to 5 As shown, the embodiments of the present invention provide a swing-scanning grille cleaning device, a flushing device for use in the sewage treatment field, and more particularly, a flushing system for mesh grilles. This swing-scanning grille cleaning device solves the problem of mesh grilles being unable to be effectively flushed in the prior art, achieving optimal flushing results using less flushing water, thereby reducing costs and increasing efficiency.

[0024] Specifically, the swing scanning grid cleaning device includes a support 10, a drive device 20, a cam mechanism 30, a connecting rod assembly 40, and a flushing assembly 50. The support 10 has an opening 11, for example, an opening 11 is provided on a side surface of the support 10, and the opening 11 connects the inner side of the support 10 with the outer side of the support 10. The drive device 20 is arranged away from the opening 11, that is, the drive device 20 will not approach the opening 11 and cause an obstruction of the opening 11. The drive device 20 is arranged on the outer side of the first end of the support 10 and is not easily stained by water. It is connected to the first end of the support 10, which facilitates the installation and connection of the drive device 20 to the support 10. The flushing assembly 50 is arranged in the support 10, and the support 10 provides support and protection for the flushing assembly 50. The flushing assembly 50 includes a flushing pipe 51 and a nozzle 52 connected to the end of the flushing pipe 51. One end of the flushing pipe 51 receives water input and outputs water through the nozzle 52. The nozzle 52 faces the opening 11 and is used to flush the objects to be flushed outside the opening 11, such as the grille mesh. The flushing pipe 51 is swingably connected to the support 10. The swing of the flushing pipe 51 drives the nozzle 52 to swing, thereby increasing the flushing range. The cam mechanism 30 is connected to the output end of the driving device 20. The connecting rod assembly 40 connects the cam mechanism 30 and the flushing pipe 51. The rotation of the cam mechanism 30 drives the connecting rod assembly 40 to move, and the connecting rod assembly 40 drives the flushing pipe 51 to swing. The support 10 also includes a mounting mechanism 12 provided on both sides of the opening 11. The mounting mechanism 12 may include, for example, a convex edge on the support 10 located on both sides of the opening 11 and a threaded fastener passing through the convex edge. The convex edge is provided with a through hole. The threaded fastener can pass through the through hole and be connected to other equipment, such as the threaded hole of the conveying device of the mesh grille. For example, it can be connected to a mesh grille dirt-blocking device in which the grille can rotate.

[0025] In this embodiment, the driving device 20 is connected to the cam mechanism 30, and the cam is connected to one end of the connecting rod assembly 40, and the other end is connected to the flushing pipe 51, so that the rotational power of the cam mechanism 30 is converted into the reciprocating motion of the connecting rod assembly 40. Under the reciprocating push-pull action of the connecting rod assembly 40, the flushing pipe 51 realizes a certain amplitude of rotation and swing, and the nozzle 52 located at the end of the flushing pipe 51 realizes a large amplitude of swing, so that the flushing water is swept and flushed in all directions on the screen without any flushing blind spot. At the same time, the flushing interval is increased by relying on the swing amplitude, and the flushing effect can be met by using less water or fewer nozzles, thereby achieving energy-saving water use and a more efficient cleaning effect.

[0026] At the same time, the entire flushing system device is independently placed outside the pollution-blocking equipment, and is connected to the equipment to be flushed by the support 10. The external flushing source can be linked with the equipment to control the flushing, and the overall disassembly, cleaning and maintenance are convenient.

[0027] In some examples, such as Figure 3As shown, the swing scanning type grid cleaning device of this embodiment adopts a swing flushing method to scan the grid mesh plate horizontally, and at the same time, under the action of the longitudinal movement of the mesh plate itself, the grid surface is flushed in all directions.

[0028] In some examples, the opening 11 is long and narrow, and there are multiple flushing assemblies 50 arranged in groups along the length of the opening 11. The flushing tube 51 swings back and forth along the length of the opening 11, so that the flushing assemblies 50 can flush significantly along the length of the opening 11.

[0029] In some examples, the connecting rod assembly 40 includes a connecting rod 41, a push-pull rod 42, and a shift rod 43, which are pivotally connected in sequence. One end of the connecting rod 41 is pivotally connected to one end of the push-pull rod 42, and the other end of the push-pull rod 42 is pivotally connected to one end of the shift rod 43. The connecting rod 41 is pivotally connected to the cam mechanism 30, which can be a circular rotating wheel connected to the output shaft of the drive device 20. The other end of the connecting rod 41 is pivotally connected to a position of the circular rotating wheel away from the center. Rotation of the circular rotating wheel pulls the connecting rod 41 to move. The connecting rod 41, in turn, drives the push-pull rod 42 to move. The shift rod 43 is pivotally connected to the flushing pipe 51. The other end of the shift rod 43 is pivotally connected to the flushing pipe 51. The pivot point of the other end of the shift rod 43 and the flushing pipe 51 can be the rotation center of the flushing pipe 51. The push-pull rod 42 passes through the support 10, extending from the outside of the support 10 into the inside of the support 10. As can be seen, the drive device 20 is connected to the cam mechanism 30, with one end of the connecting rod 41 connected to the cam and the other end connected to the push-pull rod 42. Under the action of the connecting rod 41, the cam rotational power is converted into the reciprocating motion of the push-pull rod 42. The reciprocating motion of the push-pull rod 42 can be basically along a straight line. A plurality of levers 43 are installed on the push-pull rod 42. Under the reciprocating push-pull action of the push-pull rod 42, the lever 43 swings a certain amplitude, thereby driving the flushing pipe 51 to rotate. The nozzle 52 at the end of the flushing pipe 51 swings a large amplitude, achieving a full-scale sweep of the flushing water on the screen. The flushing effect can be achieved with fewer nozzles, achieving energy-saving water use while having a more efficient cleaning effect. The above structure forms a power conversion process through the cam mechanism 30, the connecting rod 41, the push-pull rod 42, the lever 43 and other components, converting the torque output by the drive device 20 into a vector power source for the swinging, scanning and flushing of the nozzle 52.

[0030] In some examples, the swing-scanning grid cleaning device of this embodiment further includes a bearing 60 disposed on the support 10. The flushing tube 51 includes a pivot shaft 53, which can be disposed on the outer wall of the flushing tube 51. The pivot shaft 53 passes through the bearing 60, thereby enabling the pivot shaft 53 to rotate smoothly on the support 10. The shift lever 43 is connected to the pivot shaft 53. The shift lever 43 is fixedly connected to the pivot shaft 53, and the shift lever 43 drives the pivot shaft 53 to rotate.

[0031] In some examples, the support 10 includes a housing 13 and a support plate 14 disposed in the housing 13 . The bearing 60 is disposed on the support plate 14 to provide support for the flushing tube 51 so that the flushing tube 51 is located in the middle position in the housing 13 .

[0032] In some examples, the swing-scanning grille cleaning device of this embodiment further includes a water inlet pipe 54 extending through the support 10 and fixed to the support 10. The flushing assembly 50 further includes a retractable hose 55 connected between the water inlet pipe 54 and the flushing pipe 51. The high-pressure hose 55 connects the water inlet pipe 54 to each of the nozzles 52 and the flushing pipe 51. While the front end of the water inlet pipe 54 is fixed, the flushing pipe 51 at the output end can flexibly swing to achieve the desired purpose.

[0033] In some examples, the inlet of the water inlet pipe 54 is located outside the second end of the support 10, separated from the driving device 20 located at the first end of the support 10, to prevent water from entering the driving device 20, and the structural layout is reasonable.

[0034] In some examples, the driving device 20 is arranged on one side of the plane where the opening 11 is located. The driving device 20 does not cross the plane where the opening 11 is located, which facilitates the installation of the swinging scanning grille cleaning device. The driving device 20 will not interfere with equipment such as pollution-blocking equipment that has a grille to be cleaned, and can be applied to a variety of different equipment.

[0035] In some examples, the nozzle 52 includes a barrel and a rotating impeller rotatably disposed within the barrel. The barrel is used for water to flow through, and the rotating impeller rotates rapidly under the influence of the high-pressure flushing water, so that the water flushed from the nozzle forms a conical flushing surface. The nozzle 52 is a rotatable nozzle 52, which can achieve a 360-degree rotation coverage of the flushing angle, thereby increasing the flushing area.

[0036] In some examples, the driving device 20 is a reduction motor, such as an existing motor with a reduction device. The reduction motor can be driven by low power to meet the power requirements of the cleaning device, thereby achieving energy saving and emission reduction effects.

[0037] Finally, it should be emphasized that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
