Description

Technical Field

[0001] The utility model relates to the technical field of sewage cleaning, in particular to a road sewage cleaning device for municipal engineering. Background Art

[0002] Road sewage refers to sewage generated on roads, which mainly comes from rainfall, vehicle emissions and activities such as road cleaning. Road sewage may contain debris such as fallen leaves, packaging bags, and stones, which pose potential hazards to the environment and water bodies. In order to reduce the impact of road sewage on the environment, some cities will build drainage systems to collect sewage for treatment or directly discharge it to sewage treatment plants for treatment.

[0003] At present, when cleaning road sewage, the debris mixed in the sewage will flow with the sewage, and pipes are generally used to clean sewage. When the pipes suck in sewage, the filter may be blocked. If a filter is installed at the water inlet of the pipe, it will not only affect the water inlet, but also may cause the filter to be blocked. If the filter is not installed, leaves and plastic bags enter the inner cavity of the pipe with the sewage, which may cause blockage inside the pipe. Regardless of whether the water inlet of the pipe is blocked with a filter installed or the inside of the pipe is blocked without a filter installed, it takes a lot of time to clear the blockage, which affects the efficiency of cleaning sewage.

[0004] Therefore, the utility model provides a road sewage cleaning device for municipal engineering to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a road sewage cleaning device for municipal engineering, such as Figure 1 , Figure 2 and Figure 3 As shown, the cleaning device includes a treatment barrel 1, an inlet pipe 2 arranged on the treatment barrel 1, an outlet pipe 9 arranged at the lower end of the treatment barrel 1, a mounting frame 3 fixedly installed below the inlet pipe 2, a reciprocating screw 5 rotatably installed inside the treatment barrel 1, a filter plate 6 slidably installed inside the treatment barrel 1 for filtering sewage, a water wheel blade 8 sleeved on the reciprocating screw 5, and a scraping assembly arranged on the reciprocating screw 5 for scraping the filter plate 6, and the filter plate 6 is rotatably connected to the reciprocating screw 5;

[0025] The scraping assembly includes a fixed ring 15 screwed on the reciprocating screw rod 5 and a scraping plate 7 fixedly mounted on the fixed ring 15 and in contact with the filter plate 6. Bristles are provided on one side of the scraping plate 7 close to the filter plate 6. The fixed ring 15 is rotatably connected to the filter plate 6 through a bearing.

[0026] The side wall of the filter plate 6 is fixedly connected to the limit block, and the inner wall of the treatment cylinder 1 is provided with a limit groove for the limit block to slide. The sewage is introduced from the feed pipe 2, and the sewage is filtered by the filter plate 6 when passing through the filter plate 6, so that the impurities mixed in the sewage adhere to the filter plate 6. After the sewage passes through the filter plate 6, the sewage impacts the water wheel blade 8, driving the water wheel blade 8 to rotate, and the water wheel blade 8 drives the reciprocating screw 5 to rotate synchronously. Through the setting of the fixed ring 15 and the filter plate 6, the reciprocating screw 5 drives the fixed ring 15 to rotate along the surface of the reciprocating screw 5, thereby driving The scraper plate 7 rotates synchronously to scrape the surface of the filter plate 6. At the same time, when the reciprocating screw 5 rotates, the filter plate 6 slides back and forth along the surface of the reciprocating screw 5 under the limiting action of the limiting block, thereby achieving an oscillation effect, so that the impurities attached to the surface of the filter plate 6 are vibrated off, reducing the probability of clogging of the filter plate 6, and then the filter plate 6 is connected to the bearing of the fixing ring 15 through the filter plate 6. The filter plate 6 moves synchronously with the fixing ring 15, so that when the reciprocating screw 5 rotates, the scraper plate 7 scrapes the filter plate 6, and the filter plate 6 oscillates at the same time.

[0027] In order to ensure that the reciprocating screw rod 5 is firmly installed inside the treatment cylinder 1, Figure 2 and Figure 3As shown, a mounting plate 10 is fixedly connected inside the processing cylinder 1 , and a plurality of mounting plates 10 are provided, with at least two mounting plates 10 symmetrically arranged at both ends of the reciprocating screw 5 , and the mounting plates 10 are rotatably connected to the reciprocating screw 5 .

[0028] By disposing the mounting plate 10 , the reciprocating screw rod 5 can be easily installed inside the processing cylinder 1 , and the axis of the reciprocating screw rod 5 coincides with the axis of the processing cylinder 1 .

[0029] It should be noted that in order to limit the sliding position of the filter plate 6, Figure 3 and Figure 4 As shown, a limiting ring 11 for limiting the filter plate 6 is fixedly connected to the outer wall of the reciprocating screw 5 .

[0030] By setting the limiting ring 11, the sliding distance of the filter plate 6 is limited, and the reciprocating thread on the reciprocating screw rod 5 is provided between the upper mounting plate 10 and the limiting ring 11, so that the sliding of the filter plate 6 is further stabilized.

[0031] Furthermore, in order to facilitate the operator to collect and process the impurities in the treatment cylinder 1, as Figure 3 and Figure 4 As shown, the outer wall of the treatment tube 1 is fixedly connected to a treatment box 12 which is in communication with the inner cavity of the treatment tube 1 , the inner wall of the treatment box 12 is fixedly connected to a guide plate 13 , and the inner wall of the outlet pipe of the treatment box 12 is fixedly connected to a filter screen 14 .

[0032] When the filter plate 6 oscillates to remove impurities, the impurities are suspended above the filter plate 6 in the treatment tube 1, and the sewage flows into the treatment box 12, bringing the impurities therein into the treatment box 12 simultaneously, passing through the drainage plate 13, falling into the bottom of the treatment box 12, and then passing through the filter net 14 into the inner cavity of the treatment tube 1, and the impurities mixed therein remain inside the treatment box 12, and are blocked by the drainage plate 13, so that the impurities at the bottom of the treatment box 12 are not easy to flow back into the treatment tube 1, thereby improving the sewage treatment efficiency.

[0033] It should be noted that in order to improve the efficiency of sewage treatment, Figure 4 As shown, the guide plate 13 is arranged at an angle, and a plurality of guide plates 13 are provided, and the plurality of guide plates 13 are fixedly mounted on the inner wall of the processing box 12 .

[0034] By disposing a plurality of guide plates 13 , impurities at the bottom of the processing box 12 are not easily returned to the interior of the processing tube 1 .

[0035] Furthermore, in order to reduce the force of sewage impacting the filter plate 6, as Figure 4 As shown, a guide block 4 is fixedly connected to the inner wall of the treatment tube 1, and the guide block 4 is configured to be a truncated cone.

[0036] When sewage enters the interior of the treatment tube 1 through the feed pipe 2 , it is blocked by the guide block 4 , which slows down the flow rate of the sewage, reduces the force of the sewage impacting the filter plate 6 , and prolongs the service life of the filter plate 6 .

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
