Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of solid waste or solid garbage dredging, and in particular relates to a solid waste or solid garbage dredging device. Background Art
[0002] The desilting and disposal of solid waste or solid garbage has always been a difficult problem to solve. Take the disposal of solid waste or solid garbage in pipes as an example. With the development of modern cities, the pipeline system, as a core part of urban infrastructure, undertakes important tasks such as rainwater drainage and domestic sewage transportation. However, due to long-term use and lack of effective maintenance, a large amount of solid waste or solid garbage is often generated in the pipes. The main components of these solid waste or solid garbage are organic matter, minerals, grease, etc. Over time, they will gradually harden into hard sediments, forming solid waste that is difficult to move and difficult to remove, thus adhering to the inner wall of the pipe. Because these solid waste or solid garbage are large in volume and have strong adhesion, it is difficult for the water flow in the pipe to flush them away, which brings certain difficulties to the cleaning of the pipe.
[0003] While traditional drainage pipe desilting technologies can alleviate these problems to a certain extent, they all have significant limitations. For example, while high-pressure water jets can quickly remove loose dirt, they are less effective against compacted dirt. Furthermore, the high-pressure water flow can physically damage drainage pipes, shortening their service life. Mechanical scraping methods require manual access to the pipes, resulting in low efficiency and safety risks. Chemical dissolution methods can pollute the environment and are ineffective against certain types of dirt.
[0004] This solid waste or garbage not only reduces the water flow area of drainage pipes, resulting in a decrease in drainage capacity, but can also cause problems such as foul odors and mosquito breeding, seriously affecting the urban environment and residents' quality of life. Furthermore, its accumulation can cause corrosion and damage to drainage pipes, increasing maintenance costs and posing safety risks.
[0005] Therefore, how to solve the above technical problems is the difficulty faced by this application. It is necessary to invent an effective device to clean the above solid waste or solid garbage, make the pipeline unobstructed, improve its drainage capacity, and reduce various environmental problems caused by the presence of solid waste or solid garbage. Summary of the Invention

[0011] In step S1, the self-tightening inner steel ring is tightly fitted to the inner wall of the pipe end to generate internal force.
[0012] In step S2, the gas inside the vibration airbag is evacuated, tightly folded and laid on the bottom of the pipeline.

[0026] There is solidified dirt inside the pipe 4, and the dirt is solidified waste or solid garbage.

[0031] Example 2: For Example 2 of the present invention, Figure 2 、 Figure 3 、 Figure 4 Note that, descriptions of parts that are the same as those in Example 1 are omitted and are given the same reference numerals.
[0032] like Figure 2 、 Figure 3 、 Figure 4 As shown, the present invention relates to a dredging device for solid waste or solid garbage, wherein the self-tightening inner steel ring 1 is composed of a steel ring joint device 11, a steel ring body 12, an air hole interface 13, and a vibration interface 14; After the steel ring body 12 is wrapped around the inner wall of the pipe 4, it is connected end to end through the steel ring joint device 11. The outer surface of the steel ring body 12 is in close contact with the inner wall of the pipe 4. A number of side hooks 15 are arranged on the inside of the steel ring body 12. The side hooks 15 are fixedly installed with the ends of the vibrating airbag 2. The outer side of the steel ring body 12 is respectively provided with an air hole interface 13 and a vibration interface 14. The air hole interface 13 and the vibration interface 14 pass through the steel ring body 12 and are connected to the vibrating airbag 2; The steel ring joint device 11 includes a socket 111, a spigot 112, a socket bolt and a spigot bolt; The socket 111 is plugged into the socket 112; The socket 111 is threadedly connected to one side of the socket 112 via a socket bolt, and the inner side of the socket 111 is threadedly connected to the inner side of the socket 112 via a socket bolt.
[0033] The vibrating airbag 2 includes: Air pump 21, air shut-off valve 22, bladder 23, fishbone vibrator 24, steel ring airbag seal 25, oil shut-off valve 26 and engine 27; The air pump 21 is connected to the air hole interface 13 through the air closing valve 22 to inflate the bladder 23, and the engine 27 is connected to the vibration interface 14 through the oil closing valve 26; The fishbone vibrator 24 is built into the bag 23 and driven by the engine 27 . The steel ring airbag seals 25 are located at both ends of the bag 23 and are connected to the side hooks 15 .
[0034] In some embodiments, the air vent interface 13 and the vibration interface 14 use a quick-release magnetic connector, and the air vent interface 13 has a built-in pressure sensor, which automatically triggers the air pump 21 to replenish air when the air pressure in the bag 23 is lower than a set threshold.
[0035] In some embodiments, an elastic rubber gasket is provided between the socket 111 and the plug 112 of the steel ring joint device 11 to compensate for the interface gap caused by the pipe deformation and reduce the noise during the vibration transmission process.
[0036] In some embodiments, the motor 27 is equipped with a variable frequency controller to facilitate adjustment of the amplitude and frequency of the fishbone vibrator 24 .
[0037] In some embodiments, the outer surface of the bladder 23 is covered with a replaceable friction lining, and the lining material is silicon carbide particles composite rubber or polyurethane corrugated belt, which is used to increase the shear force on the interface with the dirt during vibration.
[0038] A method for desilting a solid waste or solid garbage silt removal device, comprising the following steps: S1: Install the self-tightening inner steel ring 1 on the inner wall of the end of the pipe 4; S2: Connect the vibration airbag 2 to the self-tightening inner steel ring 1; S3: After solidified dirt forms on the pipe 4, the vibration airbag 2 is activated to remove silt; S4: After the desilting is completed, the gas in the vibration airbag 2 is discharged and the pipeline 4 continues to operate.
[0039] In step S1, the self-tightening inner steel ring 1 is tightly fitted to the inner wall of the end of the pipe 4 to generate internal force.
[0040] In step S2 , the gas inside the vibrating airbag 2 is evacuated, tightly folded, and laid at the bottom of the pipe 4 .
[0041] The self-tightening inner steel ring 1 provides the pipe 4 with additional anti-deformation capability.
[0042] In some embodiments, in step S1 , an epoxy resin layer needs to be applied to the inner wall of the pipe 4 before installing the self-tightening inner steel ring 1 .
[0043] In some embodiments, in step S2 , the vibrating airbag 2 is folded in a serpentine curling manner, and the curling axis can be embedded in a rigid guide rod. Oil pulleys are provided at both ends of the guide rod to facilitate traction and laying in the pipeline 4 .
[0044] In some embodiments, in step S3, the dredging operation is carried out in two stages. In the first stage, low-frequency vibration of 5-10 Hz is used to cause interface peeling between the dirt and the inner wall of the pipe 4. In the second stage, high-frequency vibration of 20-50 Hz is switched to crush the peeled dirt.
[0045] Working principle: After the steel ring body 12 of the self-tightening inner steel ring 1 is unfolded, it is wrapped around the inner wall of the pipe 4. The socket 111 of the steel ring joint device 11 is connected to the socket 112. The socket bolts and the socket bolts are tightened in sequence to make the outer surface of the steel ring body 12 fit tightly with the inner wall of the pipe 4 to form radial prestress. Before installation, the inner wall of the pipe 4 needs to be coated with an epoxy resin layer 41. At the same time, the concentricity deviation of the steel ring should be checked to be ≤1.5mm. Fold the bag 23 of the vibrating airbag 2 into a serpentine curled state, slide it along the bottom of the pipe to the designated position, and connect the steel ring airbag seals 25 at both ends of the bag 23 through the two-way spring lock 151 of the side hook 15, ensuring that the hook slot 151 is completely locked; Start the air pump 21 to inflate the bag 23 through the quick-release magnetic air hole interface 13. The inflation pressure is 0.15-0.2 MPa. The bag expands layer by layer from bottom to top, preferentially lifting the dirt at the bottom, until the outer surface of the bag 23 is completely in contact with the inner wall of the pipe. Start the engine 27 to drive the fishbone vibrator 24. In the first stage, the low-frequency vibration of 5 Hz is continued for 10 minutes to peel off the dirt from the interface of the pipe wall. In the second stage, it is switched to the high-frequency vibration of 30 Hz and the amplitude is adjusted to 2 mm. It is continued for 15 minutes to crush and peel off the dirt. After the dredging is completed, the gas in the bag 23 is discharged through the air hole interface 13.
[0046] The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should still fall within the scope of the present invention.
