Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an inner-inflow mesh plate grille. Background Art

[0002] With the rapid development of industrial and urban construction, industrial wastewater and domestic sewage are increasing day by day. In order to prevent pollution and protect the environment, sewage must be treated. However, in the process of sewage treatment, solid waste needs to be removed first at the front end. The existing method is to set up an interception net at the front end of the river where sewage is discharged for cleaning. However, for this cleaning method, when the solid waste reaches a certain level, it will accumulate, which not only affects the flow of river water, but also requires manual salvage at irregular intervals to remove the solid waste intercepted on the interception net and transport it away. This not only has low work efficiency, but also has a large labor intensity. The cleaning work of waterworks, sewage treatment plants, pump stations, etc. is gradually replaced by mechanical operations. Therefore, related mechanical equipment has emerged, and its types have also tended to be diversified. Each type of grille decontamination machine has its own advantages and disadvantages.

[0003] When traditional inner-inflow mesh plate grilles clean the dirt accumulated on the filter plate, they mostly use jetting clean water for cleaning. However, this cleaning method will consume a large amount of water resources, resulting in excessive expenses for water resources and wasting water resources. In view of this technical problem, this application proposes an inner-inflow mesh plate grille. Content of the Utility Model

Specific implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figure 1 , Figure 3 and Figure 5, an embodiment provided by the utility model: an inner-flow screen grid, which includes a clean water tank 1 and a housing 2. The bottom side of the housing 2 is fixedly connected to the bottom side of the inner wall of the clean water tank 1. The top and bottom ends of the inner wall of the clean water tank 1 are both rotatably connected with drive rollers 3. A clean water grid belt 4 is sleeved on the outer walls of the two drive rollers 3. The driving end of a motor 5 installed at the top right side of the housing 2 is fixedly connected to the right side of the top drive roller 3. One end of a rotating shaft 11 is rotatably connected to the left side of the clean water tank 1. Two air bags 6 are arranged at the top left side of the left end of the clean water tank 1. A jet pipe 14 is installed on the top side of the housing 2. The output end of the jet pipe 14 penetrates through the top side of the inner wall of the housing 2 and is equipped with a high-pressure nozzle. Both input ends of the jet pipe 14 are connected to the output ends of the air bags 6 through air pipes 7. One end of the air pipe 7 is fixedly connected to the output end of the air bag 6, and the other end of the air pipe 7 is fixedly connected to the input end of the jet pipe 14. One-way valve diaphragms are arranged on the inner walls of the input and output ends of the air bag 6; a sewage guide plate 15 is arranged inside the housing 2. One end of the sewage guide plate 15 is fixedly connected to the left side of the inner wall of the housing 2, and the other end of the sewage guide plate 15 penetrates through the middle of the right side of the outer wall of the housing 2. An inlet 16 is arranged at the bottom right side of the outer wall of the housing 2;

[0026] Specifically, this screen grid uses the method of high-pressure gas impact to impact the dirt accumulated on the inner wall of the clean water grid belt 4, reducing the use of water resources, thereby reducing the expenses generated by water resources, saving the waste of water resources, and enhancing the awareness of natural environmental protection. When filtering sewage, sewage is injected through the inlet 16. The sewage filters into the clean water tank 1 from the inside to the outside through the clean water grid belt 4. The dirt in the sewage remains on the inner wall of the clean water grid belt, thus completing the filtration. After the air bags 6 are compressed, the air will enter the jet pipe 14 along the air pipes 7 and spray out along the high-pressure nozzles, impacting the part of the clean water grid belt 4 that has moved from the bottom to the top. The high-pressure gas impacts the inner wall of the inlet grid plate 4 along the sieve holes of the clean water grid belt 4, thus washing off the accumulated dirt. Since the dirt has a certain humidity, it is avoided that it dries and adheres to the inner wall of the clean water grid belt 4 and is easily washed off by the impact, and it falls on the sewage guide plate 15 and is led out by the inclined sewage guide plate 15.

[0027] Refer to Figures 2 - 4 , a pulley two 13 fixedly connected to the left side of the top drive roller 3. A pulley one 12 is fixedly connected to the outer wall of the rotating shaft 11. Both ends of the pulley two 13 are respectively connected to the two pulleys one 12 through belts. The shape of one of the belts is cross-shaped. A semi-gear 10 is fixedly connected to the other end of the rotating shaft 11. A rack 9 is installed on the top side of the air bag 6. The two racks 9 are located on the separated sides of the two semi-gears 10. The two racks 9 are connected by a connecting rod 8. One end of the connecting rod 8 is rotatably connected to the middle of one of the racks 9, and the other end of the connecting rod 8 is rotatably connected to the middle of the other rack 9. The middle of the connecting rod 8 is rotatably connected to the left side of the housing 2;

[0028] Specifically, since one of the pulleys 12 is driven by the belts which are cross-sleeved, the rotation direction of this pulley 12 is opposite to that of the other pulley 12. Furthermore, the rotation directions of the two half-gears 10 driven thereby are opposite. When the two half-gears 10 rotate by the same angle, they are in a mirror-symmetrical state, enabling the half-gears 10 to indirectly engage and drive the rack 9. When the rack 9 is driven by the engagement, it will undergo a downward displacement until the half-gears 10 disengage from the rack 9. While the rack 9 compresses the airbag 6, it will drive one end of the connecting rod 8 to move downward, and lift the other end connected to the other rack 9, causing the rack 9 to drive the airbag 6 to pull upward, inhale and expand, and lift the rack 9 to a height where it can engage with the half-gears 10 again, thus carrying out a cycle of inhaling and inflating. The one-way valve diaphragm supports the one-way inhalation and exhalation of the airbag 6, thereby reducing the loss during the air transportation process and improving the efficiency of gas transportation.

[0029] Working principle: When filtering sewage, sewage is injected into the water inlet 16. The sewage filters into the water purification tank 1 from the inside out through the water purification grille belt 4, and the dirt in the sewage remains on the inner wall of the water purification grille belt 4, thus completing the filtration. Meanwhile, the started motor 5 drives the top drive roller 3 to rotate, so that the drive roller 3 drives the water purification grille belt 4 to move. When the top drive roller 3 rotates, it will drive the pulley 13 on the left side to rotate, and through belt transmission, drive the pulley 12 connected to the rotating shaft 11, so that the rotating shaft 11 drives the half-gear 10 connected thereto to rotate, enabling the half-gear 10 to indirectly engage and drive the rack 9. When the rack 9 is driven by the engagement, it will undergo a downward displacement until the half-gears 10 disengage from the rack 9. While the rack 9 compresses the airbag 6, it will drive one end of the connecting rod 8 to move downward, and lift the other end connected to the other rack 9, causing the rack 9 to drive the airbag 6 to pull upward, inhale and expand, and lift the rack 9 to a height where it can engage with the half-gears 10 again. After the airbag 6 is compressed, the air will flow into the spray pipe 14 along the air delivery pipe 7 and spray out along the high-pressure nozzle, impacting the part of the water purification grille belt 4 that has moved from the bottom to the top. The high-pressure gas impacts the inner wall of the water purification grille belt 4 along the sieve holes of the water purification grille belt 4, thereby flushing down the accumulated dirt, which falls on the sewage guide plate 15.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
