Description

Technical Field

[0001] The present application relates to the technical field of pollution removal, and in particular to a screen pollution remover for sewage treatment. Background Art

[0002] The screen cleaner is a special water treatment equipment that can continuously and automatically intercept and remove various shapes of debris in the fluid. It can be widely used in urban sewage treatment, tap water industry and power plant water inlet. It can also be used as a pre-screening equipment in wastewater treatment processes in textile, food processing, papermaking, leather and other industries. It is one of the most advanced solid-liquid screening equipment in my country.

[0003] The related technology discloses a grille cleaner, which includes a cleaner body, a plurality of guide rollers rotatably arranged in the cleaner body, and a drive motor for driving the guide rollers to rotate. A grille belt is wound around the plurality of guide rollers, and a plurality of groups of rake teeth are arranged on the grille belt. A sewage outlet is also opened near the top of the cleaner body.

[0004] Since solid dirt may have a certain degree of adhesion after being soaked in water for a long time, when the grille belt cooperates with the rake teeth to carry the solid dirt to the sewage outlet, the solid dirt may adhere to the grille belt instead of falling into the sewage outlet, resulting in poor dirt removal effect of the grille dirt remover and insufficient details. Utility Model Content

[0005] In order to improve the decontamination effect of the screen decontamination machine, the present application provides a screen decontamination machine for sewage treatment.

[0006] The present application provides a sewage treatment screen decontamination machine using the following technical solutions:

[0007] A screen cleaner for sewage treatment comprises a scraper plate slidably mounted on a body of the cleaner just above a sewage outlet, the scraper plate being made of flexible rubber and abutting against a screen belt, and a reciprocating drive assembly for driving the scraper plate to move is also provided on the body of the cleaner.

[0008] By adopting the above technical solution, in the process that the grille belt brings solid dirt into the sewage outlet and returns it to the sewage, the reciprocating drive assembly can drive the scraper plate to reciprocate, so that the scraper plate can scrape off the dirt attached to the grille belt, and the scraped dirt is discharged through the sewage outlet, thereby improving the sewage removal effect of the grille cleaner.

[0009] Optionally, the reciprocating drive assembly includes a transmission roller rotatably mounted inside the dirt remover body and close to the sewage outlet, the transmission roller and the guide roller are driven by a synchronous wheel and a synchronous belt, the end of the transmission roller extends outside the dirt remover body and is coaxially provided with a rotating disk, a connecting rod is hinged on the rotating disk, and a distance is provided between the hinge between the rotating disk and the connecting rod and the axis of the rotating disk, a slider slidably arranged on the dirt remover body is hinged on the connecting rod, and the scraper plate is provided on the slider.

[0010] By adopting the above technical solution, the guide roller transmits power to the transmission roller through the synchronous belt and the synchronous wheel, the transmission roller drives the rotating disk to rotate synchronously, and the synchronous disk promotes the reciprocating linear motion of the slider through the connecting rod, so that the slider drives the scraper plate to move.

[0011] Optionally, the connecting rod is detachably connected to the rotating disk.

[0012] By adopting the above technical solution, workers can adjust the connection position between the connecting rod and the rotating disk, thereby adjusting the length of the scraping path of the scraping plate.

[0013] Optionally, a plurality of threaded holes are radially opened on the rotating disk, the threaded holes are threadedly connected with mounting bolts, and the connecting rod is rotatably sleeved on the mounting bolts.

[0014] By adopting the above technical solution, the mounting bolt cooperates with the multiple threaded holes to achieve the adjustment of the connection position between the connecting rod and the rotating disk.

[0015] Optionally, a sliding hole is radially opened in the rotating disk, a sliding column slides in the sliding hole, one end of the sliding column extends outside the sliding hole, and a compression spring is supported between the other end and the closed end of the sliding hole; a plurality of through holes are opened on the sliding column along its length direction, and a plurality of plug holes are opened from the outside of the rotating disk to the inside, the plug holes are communicated with the through holes and correspond one to one, and a plug pin is provided at the end of the connecting rod, the plug pin is plug-matched with the plug hole, the plug pin slides through the through hole, and a groove is circumferentially opened on the plug pin to engage with the sliding column.

[0016] By adopting the above technical solution, the worker presses the sliding column into the sliding hole so that all the through holes on the sliding column are aligned with the corresponding plug-in holes. Then the worker inserts the plug pin into the appropriate plug-in hole and then releases the sliding column. The deformation force of the compression spring will push the sliding column outward from the sliding block, and the sliding column will be inserted into the slot on the plug pin, thereby realizing the adjustment of the hinge position of the connecting rod and the rotating disk.

[0017] Optionally, a step is provided at a position of the sliding hole near its closed end, and when the end of the sliding column abuts against the step, the through hole and the plug hole are exactly coaxial.

[0018] By adopting the above technical solution, the step limits the maximum pressing depth of the sliding column, which is conducive to achieving the alignment of the through hole and the plug hole.

[0019] Optionally, the cross-sections of the plug hole and the sliding column are both rectangular.

[0020] By adopting the above technical solution, the rectangle can limit the circumferential rotation of the sliding column relative to the plug hole, reducing the possibility that the through hole and the plug hole are circumferentially staggered, making it difficult for the plug pin to pass through the through hole.

[0021] Optionally, one end of the plug pin that slides through the through hole is configured in a hemispherical shape.

[0022] By adopting the above technical solution, the hemispherical shape facilitates the insertion of the plug pin through the through hole.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the grille belt brings solid dirt into the sewage outlet and returns to the sewage, the reciprocating drive assembly can drive the scraper to reciprocate, so that the scraper can scrape off the dirt attached to the grille belt, and the scraped dirt is discharged through the sewage outlet, thereby improving the sewage removal effect of the grille decontamination machine;

[0025] 2. The guide roller transmits power to the transmission roller through the synchronous belt and the synchronous wheel. The transmission roller drives the rotating disk to rotate synchronously. The synchronous disk promotes the reciprocating linear motion of the slider through the connecting rod, so that the slider drives the scraper to move. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The embodiment of the present application discloses a screen dirt remover for sewage treatment.

[0032] Example 1

[0033] Reference Figure 1 and Figure 2 The screen dirt remover for sewage treatment comprises a dirt remover body 1, a plurality of guide rollers rotatably mounted inside the dirt remover body 1, a driving motor for driving the guide rollers to rotate, a screen belt 4 is wound around the plurality of guide rollers, and a sewage outlet (not shown in the figure) is opened on the dirt remover body 1.

[0034] The cleaning machine body 1 is provided with a scraper plate 3 which is horizontally slidably mounted above the sewage outlet. The scraper plate 3 is made of flexible rubber material and contacts the grille belt 4. The cleaning machine body 1 is also provided with a reciprocating drive assembly for driving the scraper plate 3 to move.

[0035] Reference Figure 1 and Figure 2 The reciprocating drive assembly includes a transmission roller 5 rotatably mounted in the sewage remover body 1. The transmission roller 5 is horizontal and close to the sewage outlet. The transmission roller 5 and the guide roller are driven by a synchronous wheel 6 and a synchronous belt 7.

[0036] Both ends of the driving roller 5 extend outside the dirt remover body 1 and are coaxially bolted with a rotating disk 8, on which a connecting rod 9 is hinged, and there is a distance between the hinge of the rotating disk 8 and the connecting rod 9 and the axis of the rotating disk 8. The other end of the connecting rod 9 relative to the rotating disk 8 is hinged with a slider 10 that slides on the dirt remover body 1, and the end of the scraper 3 is bolted to the slider 10.

[0037] Reference Figure 1 and Figure 2 The driving motor drives the guide roller to rotate, and the guide roller drives the transmission roller 5 to rotate through the synchronous wheel 6 and the synchronous belt 7. The transmission roller 5 drives the rotating disk 8, so that the connecting rod 9 pushes the slider 10 to slide back and forth linearly, and the slider 10 drives the scraper plate 3 to move, thereby scraping the grille belt 4, thereby improving the decontamination effect of the grille decontamination machine on sewage.

[0038] Reference Figure 1 and Figure 2 A plurality of threaded holes 81 are radially opened on the rotating disk 8, and a mounting bolt 11 is threadedly connected to any threaded hole 81. The connecting rod 9 is rotatably sleeved on the mounting bolt 11. Through the detachable connection between the connecting rod 9 and the rotating disk 8, the worker can adjust the hinge position of the connecting rod 9 and the rotating disk 8, thereby adjusting the length of the scraping path of the scraper plate 3.

[0039] The implementation principle of Example 1 is as follows: the driving motor in the prior art drives the guide roller to rotate, the guide roller transmits power to the transmission roller 5 through the synchronous belt 7 and the synchronous wheel 6, the transmission roller 5 drives the rotating disk 8 to rotate synchronously, and the synchronous disk promotes the reciprocating linear motion of the slider 10 through the connecting rod 9, so that the slider 10 drives the scraper plate 3 to move, thereby scraping off the residual dirt on the grille belt 4.

[0040] Example 2

[0041] Reference Figure 3 The difference between this embodiment and embodiment 1 is that a sliding hole 82 is radially opened in the rotating disk 8, one end of the sliding hole 82 is closed, and the other end extends to the circumferential outer wall of the rotating disk 8, and a sliding column 12 slides in the sliding hole 82.

[0042] Reference Figure 3 One end of the slide post 12 extends out of the sliding hole 82 , and a compression spring 13 is supported between the other end and the closed end of the sliding hole 82 . A plurality of through holes 121 are formed on the slide post 12 along its length direction.

[0043] A plurality of plug holes 83 are opened on the outside of the rotating disk 8 and the inside thereof, and the plug holes 83 are communicated with the through holes 121 and correspond one to one, and a plug pin 14 is integrally formed at the end of the connecting rod 9, and the plug pin 14 is plugged into and matched with the plug hole 83 and the plug pin 14 slides through the through hole 121, and an annular groove 141 is opened circumferentially on the plug pin 14 and is used to engage with the sliding column 12.

[0044] Reference Figure 3 The worker presses the slide post 12 into the sliding hole 82 so that each through hole 121 on the slide post 12 is aligned with the corresponding plug-in hole 83. Then the worker inserts the plug pin 14 into the appropriate plug-in hole 83 and then releases the slide post 12. The deformation force of the compression spring 13 pushes the slide post 12 out of the sliding hole 82, and the slide post 12 is inserted into the slot 141 on the plug pin 14, thereby realizing the adjustment of the hinge position of the connecting rod 9 and the rotating disk 8.

[0045] Reference Figure 3 One end of the plug pin 14 that slides through the through hole 121 is configured in a hemispherical shape, thereby facilitating the plug pin 14 to pass through the through hole 121 .

[0046] Reference Figure 3 The cross-sections of the plug hole 83 and the slide post 12 are both rectangular, thereby limiting the rotation of the slide post 12 relative to the plug hole 83 and reducing the possibility that the plug holes 83 are circumferentially staggered with each other, making it difficult for the plug pin 14 to pass through the through hole 121.

[0047] Reference Figure 3A step 15 is arranged near the closed end of the sliding hole 82. When the end of the sliding column 12 contacts the step 15, the through hole 121 and the plug hole 83 are exactly coaxial. The step 15 facilitates the one-to-one alignment of the through hole 121 and the plug hole 83, thereby facilitating the insertion of the plug pin 14 through the through hole 121 on the sliding column 12.

[0048] The implementation principle of Example 2 is as follows: the worker presses the slide post 12 into the sliding hole 82, and the compression spring 13 is compressed until the end of the slide post 12 hits the step 15. At this time, the through hole 121 is aligned with the plug hole 83 one by one. The worker inserts the plug pin 14 into the appropriate plug hole 83, and then releases the slide post 12. The deformation force of the compression spring 13 will push the slide post 12 out of the sliding hole 82, and the slide post 12 will be inserted into the slot 141 on the plug pin 14, thereby realizing the adjustment of the hinge position of the connecting rod 9 and the rotating disk 8.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
