Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to an underground type drug-adding pipeline pollution-blocking dredging device. Background Art

[0002] Since industrial water systems need to be regulated and treated to meet the system's effluent water quality requirements, common dosing pipeline layouts include gallery type and underground type. Due to factors such as site environment and pipeline leakage safety hazards, underground layout is often used; in order to ensure the long-term and stable operation of dosing pipelines, GB50242-2002 "Construction Quality Acceptance Code for Building Water Supply, Drainage and Heating Engineering" and GB50235-97 "Industrial Metal Pipeline Engineering Construction and Acceptance Code" and other specifications have put forward specific and clear requirements for the laying of underground pipelines to ensure safe use.

[0003] During the long-term operation of the dosing pipeline, factors such as impurities in the drug itself, pipeline corrosion, and land environment can lead to pipeline blockage, reduced equipment output, and even no drug delivery from the pipeline, which directly affects the water quality of the system and the system's exit from operation. The current solution and treatment measures are usually civil excavation and pipeline replacement, but this approach will affect the municipal image, increase maintenance costs, reduce dredging efficiency, and even cause environmental incidents.

[0040] See also Figure 1-5 A buried drug-adding pipeline blockage dredging device includes a main pipeline 1, an inlet end 2 provided on one side of the main pipeline 1 and used for adding drugs, and an outlet end 3 provided on the other side of the main pipeline 1 and used for outputting drugs, a first valve 4 is provided on one side of the main pipeline 1 close to the inlet end 2, and a second valve 5 is provided on one side of the main pipeline 1 close to the outlet end 3, and further includes:

[0041] The scraping mechanism 11 includes a connecting pipe 10 connected to the main pipeline 1 near the first valve 4, a plurality of circumferentially distributed scrapers 1105 slidingly extended into the main pipeline 1 through the connecting pipe 10 and used to loosen the dirt, and a power component arranged on the scraper 1105 and used to push and pull the scraper 1105 close to the inner wall of the main pipeline 1;

[0042] The dredging mechanism is connected to the main pipeline 1 and inputs water for flushing the main pipeline 1 or compressed air for purging the main pipeline 1 into the main pipeline 1.

[0043] With such a design, the scraping mechanism 11 extends into the main pipe 1, and the scraper 1105 loosens the dirt on the inner wall of the main pipe 1. According to the diameter of the main pipe 1, the power component drives the scraper 1105 to approach the inner wall of the main pipe 1, so that the scraper 1105 is tightly attached to the inner wall of the main pipe 1. The scraper 1105 loosens the dirt on the inner wall of the main pipe 1 to prevent the dirt from adhering to the inner wall of the main pipe 1, which facilitates the operation of the dredging mechanism, that is, when water for flushing the main pipe 1 or compressed air for blowing the main pipe 1 is input into the main pipe 1, it is easy for the water or compressed air to carry away the dirt.

[0044] In one embodiment, the scraping mechanism 11 further includes:

[0045] The connecting rod 1102 slides into the main pipeline 1;

[0046] A handle 1101 is connected to an end of the connecting rod 1102 away from the scraper 1105;

[0047] The fixing ring 1103 is connected to the connecting rod 1102 and allows the scraper 1105 to move close to the inner wall of the main pipeline 1. The fixing ring 1103 is provided with a limiting groove 1104 for the scraper 1105 to move.

[0048] With this design, the handle 1101 is fixedly connected to the connecting rod 1102 .

[0049] In one embodiment, the power assembly comprises:

[0050] A connecting block 1110 is slidably disposed on one side of the connecting rod 1102;

[0051] The push-pull rod 1106 has one end hinged to the connection block 1110, and the other end passes through the fixing ring 1103 and is hinged to the scraper 1105. When the connection block 1110 slides, the push-pull scraper 1105 moves in the limiting groove 1104. The limiting groove 1104 is provided with a through groove 1112 for the push-pull rod 1106 to pass through.

[0052] The power member is disposed on the connecting block 1110 and is used to drive the connecting block 1110 to slide.

[0053] With this design, the limiting groove 1104 is connected to the through groove 1112 .

[0054] In one embodiment, the power member comprises:

[0055] The threaded rod 1111 is connected to one end of the connecting block 1110 close to the connecting rod 1102;

[0056] The threaded sleeve 1109 is connected to one end of the connecting rod 1102 and sleeved on the threaded rod 1111, and is threadedly connected to the threaded rod 1111;

[0057] The fixing ring 1108 is rotatably connected to one end of the threaded sleeve 1109 close to the threaded rod 1111 and is slidably connected to the threaded rod 1111 . The fixing ring 1108 is connected to a plurality of fixing rods 1107 which are distributed in a circle and connected to the fixing ring 1103 .

[0058] With this design, the threaded sleeve 1109 is fixedly connected to the connecting rod 1102; one end of the fixing rod 1107 is fixedly connected to the fixing ring 1103, and the other end is fixedly connected to the fixing ring 1103;

[0059] By rotating the connecting rod 1102, the threaded sleeve 1109 rotates, causing the threaded rod 1111 to move, driving the connecting block 1110 to move, and the push-pull rod 1106 drives the scraper 1105 to slide in the limiting groove 1104 and approach the inner wall of the main pipe 1, thereby allowing the scraper 1105 to adapt to main pipes 1 of different diameters; it is worth noting that the push-pull rod 1106 only swings in the moving direction of the connecting block 1110, so the fixed rod 1107, the fixed ring 1108 and the fixed ring 1103 are used in combination to limit the threaded rod 1111, thereby preventing the threaded rod 1111 from rotating with the rotation of the threaded sleeve 1109.

[0060] In one embodiment, the dredging mechanism comprises:

[0061] A feed pipe 6 is connected to the main pipeline 1 at one side close to the first valve 4 and is used to input water or compressed air into the main pipeline 1;

[0062] The discharge pipe 9 is connected to one side of the main pipeline 1 close to the second valve 5, and discharges the dirt in the main pipeline 1 to the outside of the main pipeline 1 under the flushing of water or the heavy sweeping of compressed air.

[0063] With this design, it is determined whether the pipeline is blocked by dirt according to the operating parameters, such as the outlet pressure of the dosing pump and the outlet flow of the pipeline, and a regular cleaning cycle is formulated and optimized. When the main pipeline 1 needs to be cleared and cleaned, the dirt in the main pipeline 1 is first loosened by the scraper 1105 to prevent the dirt from adhering to the inner wall of the main pipeline 1; then, the first valve 4 and the second valve 5 are operated to make the area between the first valve 4 and the second valve 5 on the main pipeline 1 closed, and the medicine cannot flow through this area, and then water or compressed air is input into the feed pipe 6 to flush or purge the main pipeline 1, and drive the dirt to be discharged from the discharge pipe 9; it is worth noting that the choice of inputting water or compressed air depends on the type of medicine. For example, when the medicine is sulfuric acid, only compressed air can be input into the main pipeline 1 for purging.

[0064] In one embodiment, the dredging mechanism further comprises:

[0065] A third valve 7 is provided on the feed pipe 6 and is used to open or close the feed pipe 6;

[0066] The fourth valve 8 is disposed on the discharge pipe 9 and is used to open or close the discharge pipe 9 .

[0067] Working principle: When in use, the scraping mechanism 11 extends into the main pipe 1, and the scraper 1105 loosens the dirt on the inner wall of the main pipe 1. According to the size of the diameter of the main pipe 1, the power component drives the scraper 1105 to approach the inner wall of the main pipe 1, so that the scraper 1105 is close to the inner wall of the main pipe 1. The scraper 1105 loosens the dirt on the inner wall of the main pipe 1 to prevent the dirt from adhering to the inner wall of the main pipe 1, which is convenient for the operation of the dredging mechanism, that is, when water for flushing the main pipe 1 or compressed air for blowing the main pipe 1 is input into the main pipe 1, it is easy for water or compressed air to carry away the dirt.
