Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment pipe backwashing device. Background Art

[0002] Sewage usually refers to the discharged water from life and production that is polluted to a certain extent. This discharged water cannot be discharged casually. If it is discharged casually, it will cause the water in nature to be polluted, thus causing more serious environmental pollution. Therefore, sewage needs to be treated in advance before discharge.

[0003] The pipeline backflushing devices currently in use generally prevent sewage from surging up, and some are even more effective in completely backflushing the dirt in the pipes at one time. However, the backflushing devices have certain shortcomings. They ignore the sludge attached to the inner wall of the sewage pipe. This sludge not only causes odor, but also corrodes the inner wall of the pipe, affecting the service life of the pipe. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A sewage treatment pipe backwashing device comprises a drainage module and a backwashing module, wherein the drainage module comprises an outlet pipe, a filter pipe arranged at the bottom of the outlet pipe, a connecting water pipe connected between the outlet pipe and the filter pipe, a guide plate installed inside the filter pipe, and a plurality of through holes opened at the bottom of the filter pipe, and the backwashing module comprises a curved rod slidably connected between the outlet pipe and the connecting water pipe, a floating plate connected to the bottom end of the curved rod, a horizontal plate connected to the top end of the curved rod, and an annular scraper sleeved on the outer side of the horizontal plate, wherein the annular scraper fits the inner wall of the outlet pipe.

[0007] By adopting the above technical solution, when a large amount of sewage is discharged from multiple through-hole positions, the sewage will float due to untimely discharge, which makes the float plate reciprocate with the curved rod, horizontal plate, and annular scraper, and then the annular scraper cleans the inner wall of the outlet pipe, effectively preventing sludge from adhering, which avoids the breeding of odor, reduces the erosion of the inner wall of the pipe by sludge, and ensures the service life of the pipe.

[0008] In a preferred example, the utility model can be further configured as follows: the water outlet pipe is connected to the inside of the filter pipe through a connecting water pipe, and the water outlet pipe, the filter pipe and the connecting water pipe are all made of stainless steel.

[0009] In a preferred example, the utility model can be further configured as follows: the guide plate is made of plastic material, and the top of the guide plate is set as an inclined surface.

[0010] In a preferred example, the utility model can be further configured as follows: a plurality of through holes are irregularly arranged and communicated with the interior of the filter pipe.

[0011] In a preferred example, the utility model can be further configured as follows: the floating plate is arranged on the top of the plurality of through holes, and the floating plate is made of foam material.

[0012] In a preferred example, the utility model can be further configured as follows: a filter plate is inserted into the water outlet pipe through interference fit, and the filter plate is arranged on the top of the annular scraper.

[0013] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0014] 1. In the utility model, when a large amount of sewage is discharged from multiple through-hole positions, the sewage will float due to untimely discharge, which makes the float plate reciprocate with the curved rod, the horizontal plate and the annular scraper, and then the annular scraper cleans the inner wall of the outlet pipe, effectively preventing the sludge from adhering, which avoids the breeding of odor, reduces the erosion of the inner wall of the pipe by the sludge, and ensures the service life of the pipe.

[0015] 2. In the utility model, when sewage flows through the outlet pipe, it will be filtered by the filter plate, and then some large-volume dirt will be intercepted, which reduces the probability of blockage of the outlet pipe and the downstream pipe, and ensures that the sewage treatment operation can proceed smoothly.

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0024] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0025] A sewage treatment pipe backwashing device provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.

[0026] Embodiment 1:

[0027] Combination Figure 1-3 As shown, the utility model provides a sewage treatment pipe backwashing device, including a drainage module 100 and a backwashing module 200, wherein the drainage module 100 includes an outlet pipe 110, a filter pipe 120 disposed at the bottom of the outlet pipe 110, a connecting water pipe 130 connected between the outlet pipe 110 and the filter pipe 120, a guide plate 140 installed inside the filter pipe 120, and a plurality of through holes 150 opened at the bottom of the filter pipe 120;

[0028] The recoil module 200 includes a curved rod 210 slidably connected between the outlet pipe 110 and the connecting water pipe 130, a floating plate 220 connected to the bottom end of the curved rod 210, a horizontal plate 230 connected to the top end of the curved rod 210, and an annular scraper 240 sleeved on the outside of the horizontal plate 230, wherein the annular scraper 240 is in contact with the inner wall of the outlet pipe 110.

[0029] Furthermore, the water outlet pipe 110 is connected to the inside of the filter pipe 120 through the connecting water pipe 130. The water outlet pipe 110, the filter pipe 120 and the connecting water pipe 130 are all made of stainless steel. The same material is selected to reduce the difficulty of material selection when manufacturing the device.

[0030] Furthermore, the plurality of through holes 150 are arranged irregularly and are connected to the interior of the filter pipe 120 . This structural design ensures that the sewage in the filter pipe 120 can be smoothly discharged from the through holes 150 .

[0031] Furthermore, the floating plate 220 is arranged on the top of the multiple through holes 150. The floating plate 220 is made of foam material. The floating plate 220 made of foam material can rise and fall sensitively when sewage surges up, ensuring that the annular scraper 240 can clean up the sludge on the inner wall of the outlet pipe 110.

[0032] Embodiment 2:

[0033] Combination Figure 1-3As shown, based on the first embodiment, the guide plate 140 is made of plastic material, and the top of the guide plate 140 is set as an inclined surface. With this structural design, the sewage can be guided to flow accurately to the multiple through holes 150.

[0034] Embodiment three:

[0035] Combination Figure 1-3 As shown, in the above embodiment, a filter plate 300 is inserted in the outlet pipe 110 in an interference fit, and the filter plate 300 is arranged on the top of the annular scraper 240. The filter plate 300 can filter large volume of dirt in the sewage and effectively prevent the outlet pipe 110 from being blocked.

[0036] The working principle and use process of the utility model are as follows: when the device is put into actual use, the sewage enters the connecting water pipe 130 from the outlet pipe 110, and then enters the filter pipe 120. During this process, the filter plate 300 screens out large-volume dirt, while small-volume dirt enters the top of the multiple through holes 150, and then cooperates with the continuously flowing out sewage. Since the drainage speed of the filter pipe 120 is lower than the water inlet speed of the connecting water pipe 130, the sewage will float at the positions of the multiple through holes 150, and then rise and fall against the floating plate 220, and then the horizontal plate 230 and the annular scraper 240 connected to the floating plate 220 by the curved rod 210 are reciprocated and lifted, thereby realizing the cleaning of the inner wall of the outlet pipe 110 and effectively preventing sludge from adhering, which avoids the breeding of odor and also ensures the service life of the pipe.
