Description
Technical Field
[0001] The utility model relates to the field of sewage treatment, in particular to a rotary fine grid dirt remover with a cleaning mechanism. Background Art
[0002] The screen cleaner is a device used to filter water bodies. It separates impurities in the water body through screen machines and screw conveyors to achieve the purpose of cleaning water quality. In the existing sewage treatment process, it is necessary to set up a multi-stage screen cleaner according to the number and size of impurities in the sewage. In the sewage filtration process, the coarse screen set at the front end of the sewage inflow direction is first used to filter impurities such as branches and large garbage in the sewage, and then the fine screen set at the rear end of the sewage inflow direction is used to filter smaller particles in the sewage. This step-type screen filtration system is widely used in the field of sewage treatment due to its non-stop continuous operation characteristics.
[0003] However, in actual use, the existing fine grid decontamination machine needs to filter smaller impurities in the water, so the grid holes on the grid are small in diameter and are often blocked by impurities such as small stones, causing its water flow to deteriorate and affecting the efficiency of sewage treatment. In response to the above technical problems, the designers set a cleaning brush at the discharge end of the existing fine grid decontamination machine to brush the grid holes, which reduces the blockage of the grid holes to a certain extent. However, the brush is made of flexible material. When impurities such as small stones are stuck in the grid holes under the impact of water flow, the flexible brush is difficult to clean them. After the fine grid decontamination machine has been used for a period of time, the cleaning effect of the brush will be greatly reduced, affecting its water flow performance. Utility Model Content

[0052] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the push cleaning mechanism further includes a push block 218 with a V-shaped front end, and the push block 218 slides along the inner walls of the two first sliding blocks 206 and the two second connecting plates 207;
[0053] The included angle between the two end faces of the front end of the push block 218 is the same as the included angle between the two end faces of the V-shaped grid plate 101 , and the rear end of the push block 218 is connected to the rear end of the first sliding block 206 via a fourth spring 219 .
[0054] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the push cam 202 is located on the inner side of the plurality of push cleaning mechanisms;

[0056] In this embodiment, there are six groups of push cleaning mechanisms, the retracting section 2022 is located on the side away from the discharge end of the rotary fine grid dirt remover 1, the three groups of push cleaning mechanisms located on this side, the third spring 217 and the fourth spring 219 are all in a natural state, and the front end of the push cleaning mechanism does not contact the V-shaped grid plate 101, and this state is defined as the initial state. The push section 2021 is located on the side close to the discharge end of the rotary fine grid dirt remover 1, the three groups of push cleaning mechanisms located on this side, the third spring 217 is in a stretched state, the fourth spring 219 is compressed, the first spring 211 and the second spring 212 are in a stretched state, and the cleaning column 213 is inserted into the grid hole 102, and this state is defined as the cleaning completion state.

When the push cleaning mechanism retreats, the above process is opposite.
[0058] In this embodiment, when the limiting protrusion 216 is in contact with the inner end surface of the V-shaped grid plate 101 , the cleaning column 213 does not contact with the inner end surface of the V-shaped grid plate 101 .

During the initial installation, the pushing cleaning mechanism is aligned with the V-shaped screen plate 101 rotating around the first sprocket 106. During the circular motion of the annular screen, the three groups of pushing cleaning mechanisms close to the discharge end can always be stably inserted into the corresponding V-shaped screen plate 101 for cleaning operations.
[0062] In this embodiment, sprockets are provided at the feed end below the ring chain 104 and at the corner position in the middle for alignment and guidance, and the sprockets are rotatably mounted on the two side walls of the frame 103 via mounting shafts.
[0063] As an embodiment of the present utility model, the number of the V-shaped grid plates 101 is an odd number, and the array angle between adjacent pushing and cleaning mechanisms is equal to twice the angle between adjacent V-shaped grid plates 101 rotating around the first sprocket 106 .
[0064] In this embodiment, there are six groups of pushing cleaning mechanisms, with a total of 81 V-shaped grating plates 101 (other odd numbers can also be set according to the depth of sewage to meet the usage requirements), the array angle between adjacent pushing cleaning mechanisms is 60°, and the angle between adjacent V-shaped grating plates 101 rotating around the first sprocket 106 is 30°, that is, the pushing cleaning mechanism cleans the V-shaped grating plates 101 at intervals, and the 81 V-shaped grating plates 101 are numbered 1 to 81 in sequence. When the annular grille rotates the first circle, the pushing cleaning mechanism cleans the 1st, 3rd, ..., 81st V-shaped grating plates 101. When the annular grille rotates the second circle, the 1st V-shaped grating plate 101 adjacent to the 81st V-shaped grating plate 101 is skipped, and the 2nd, 4th, ..., 80th V-shaped grating plates 101 are cleaned. The cleaning of all V-shaped grating plates 101 can be completed by two cycles of the annular grille.
[0065] In this embodiment, since the size of the inner ring is limited, a V-shaped grid plate 101 is provided to clean the intervals and meet the use requirements and the need for installation space.
[0066] As an embodiment of the utility model, a cleaning pipeline (not shown in the figure) for cleaning the V-shaped grid plate 101 is also provided on the outer side of the discharge end of the rotary fine grid cleaner 1, and a plurality of cleaning nozzles (not shown in the figure) are provided on the cleaning pipeline.

At the same time, when the pushing cleaning mechanism pushes out the impurities stuck in the grid hole 102, the cleaning nozzle flushes the pushed out impurities into the screw feeder. In this embodiment, the water inlet end of the cleaning pipeline is connected to the water outlet end of the pumping component, and the pumping component is used to pump the water filtered by the fine grid for cleaning operations.
