Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to a cleaning rod for sewage treatment and a cleaning method. Background Art

[0002] Wastewater treatment is the process of purifying wastewater to meet the quality requirements for discharge into a water body or reuse. Domestic sewage, the wastewater generated by daily life, is a complex mixture of various inorganic and organic substances, including: ① floating and suspended solid particles of varying sizes; ② colloidal and gelatinous dispersions; and ③ pure solutions.

[0003] The sewage treatment process will undergo multiple sedimentation treatments. The first sedimentation will separate the larger suspended matter in the sewage from the water body by standing still, such as aquatic plants, plastic bags, etc. The suspended matter on the surface needs to be salvaged, and then by adding reaction agents, the suspended particles in the sewage will settle after the reaction. After the treated water after the reaction is transported to the next reaction tank, the sediment at the bottom of the tank needs to be scraped and cleaned.

[0004] During the sewage treatment process, sedimentation tanks are primarily cleaned using a scoop rod with a mesh bag or a cleaning rod with a scraper. These are used to salvage floating debris from the surface and scrape debris from the bottom, respectively. Existing cleaning rods are simple in structure, typically simply attaching a mesh bag or scraper to the front of the bamboo pole, or featuring adjustable lengths. Different cleaning needs require different cleaning tools. Damage to the rod requires replacement. To salvage as many floating objects as possible at once, the opening of the net bag should be as large as possible. However, larger openings can increase the risk of floating objects falling from the bag or becoming too large, potentially causing them to fall during handling. Summary of the Invention

[0029] The following is a non-limiting detailed description of the technical solutions of the present invention in conjunction with preferred embodiments and the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0030] As shown in the figure, the present invention provides a technical solution: a cleaning rod and a cleaning method for sewage treatment, comprising an adjusting rod 1, a salvage net assembly 2 and a scraper assembly 3, wherein the adjusting rod 1 has an adjustable rod length and is a hollow structure as a whole, and the salvage net assembly 2 and the scraper assembly 3 are assembled on the adjusting rod 1 as required; the salvage net assembly 2 comprises a skeleton 21, a net bag 22 and a fixing rope group 23, wherein the area enclosed by the skeleton 21 should be as large as possible, and the two ends of the skeleton 21 are passed through the holes set at the end of the adjusting rod 1 and fixed by fixing elements, and the edge of the net bag 22 is provided with several rings 221, and the surface is provided with mesh holes 222, which is sleeved on the skeleton 21, and the fixing rope group 23 has two groups, one group is fixed on the boundary of the net bag 22 facing the adjusting rod 1, and the other group is fixed on the skeleton 21.

[0031] The skeleton 21 includes two parts: a fixed frame 211 and a flexible frame 212. The fixed frame 211 has a fixed shape and is not easily deformed. The flexible frame 212 is where the net bag 22 is placed and where the fixed rope group 23 is fixed. The whole is made of flexible material and can maintain its inherent shape without applying external force.

[0032] The fixing rope assembly 23 includes a fixing ring 231 , an extension rope 232 and a wristband 233 , wherein two ends of the extension rope 232 are respectively connected to the fixing ring 231 and the wristband 233 , and one end connected to the wristband 233 passes through the interior of the adjusting rod 1 .

[0033] During the actual salvage process, different functions can be achieved by pulling the two fixing rope groups 23, specifically: the fixing rope group 23 on the net bag 22 can be used to pull open the opening of the net bag 22 to make the opening as large as possible. At the same time, because it is pulled in the direction of the adjusting rod 1, the skeleton 21 as a whole is further reinforced, which can prevent the skeleton 21 from being separated from the adjusting rod 1 when the fixing component fails; the fixing rope group 23 on the skeleton 21 plays a role in transporting the salvaged objects. Because the flexible frame 212 is easy to deform, it bends one side to the other side under the pulling of the fixing rope group 23, which can cover the internal objects and achieve a certain fixed sealing effect, which can effectively prevent the internal salvaged objects from falling off during transportation.

[0034] The scraper assembly 3 includes a support rod 31, a first fixed sleeve 32, a scraper group 33, a collecting bag group 34 and an adjustment group 35, wherein the support rod 31 is passed through the adjusting rod 1, the first fixed sleeve 32 is fixed at one end of the adjusting rod 1 and can allow the support rod 31 to pass through, the scraper group 33 is fixed at the end of the support rod 31, the collecting bag group 34 is arranged on the scraper group 33, and the adjustment group 35 is arranged at the other end of the support rod 31.

[0035] The scraper assembly 33 includes a middle fixed block 331 , a knife holder 332 , and a scraper 333 , wherein the knife holder 332 is fixed to the lower side of the middle fixed block 331 , and the scraper 333 is fixed on the knife holder 332 , and has an arc-shaped structure.

[0036] The collecting bag group 34 includes a fixing rod 341, two limit blocks 342, a limit twist 343, a connecting rope 344 and a placement bag 345, wherein one end of the fixing rod 341 is fixed to the outward side of the knife holder 332, the placement bag 345 passes through the fixing rod 341, the lower side is in contact with the upper surface of the knife holder 332, and the upper outward end is limited to a certain height by the two limit blocks 342, the limit twist 343 is fixed on the middle fixing block 331 and is consistent with the height of the limit block 342, and the connecting rope 344 connects the upper inward end of the placement bag 345 and the limit twist 343.

[0037] The adjustment group 35 includes a second fixing sleeve 351, a handle 352 and a fixed block 353, wherein the second fixing sleeve 351 is fixed to the other end of the adjustment rod 1 and allows the support rod 31 to extend, the handle 352 is fixed to the end of the support rod 31, and the second fixing sleeve 351 and the support rod 31 are correspondingly provided with a card slot matching the fixed block 353.

[0038] In actual operation, the angle of the scraper assembly 33 at the other end is adjusted by rotating the handle 352 , and after the adjustment is completed, the fixed block 353 is embedded to limit the position.

[0039] The adjusting rod 1 includes a main rod 11, a secondary rod 12 and an extension rod 13, wherein the inner walls of both ends of the main rod 11 are provided with a section of thread, and the outer wall of the secondary rod 12 is provided with a thread matching the main rod 11. The extension rod 13 is connected to the main rod 11 to increase the overall length.

[0040] In actual operation, there are two main ways of assembling the secondary rod 12, the main rod 11 and the extension rod 13. One is that when a longer distance is actually required, the threaded end of the secondary rod 12 can be directly screwed into the thread on one side of the main rod 11, and the other end of the main rod 11 is connected to the extension rod 13. This is the longest state of the adjusting rod 1; if the actual required distance is not long, the unthreaded end of the secondary rod 12 can be passed through the main rod 11 until the threaded end contacts the threaded part of the main rod 11, and then rotated to connect, and then the extension rod 13 is connected as required. At this time, the overall length of the adjusting rod 1 can be shortened, and the connection method between the main rod 11 and the extension rod 13 can be a groove connection or a threaded connection.

[0041] The specific cleaning methods are as follows:

[0042] S1. Assemble the rod: According to the distance of the cleaning position, select the assembly method of the adjustment rod to change the overall length of the rod;

[0043] S2. Accessories selection: If you need to salvage floating objects on the water surface, assemble the salvage net assembly on the adjusting rod. If you need to scrape off the attachments on the bottom of the sedimentation tank, assemble the scraper assembly on the adjusting rod.

[0044] S3a. Salvaging floating objects: During the salvaging process, the fixed rope group 23 connected to the net bag 22 is always pulled to make the net bag 22 as large as possible. After salvaging as many floating objects as possible, the fixed rope group 23 connected to the flexible frame 212 is pulled to bend the flexible frame 212, thereby pressing the salvaged objects, and then transferring the salvaged objects out of the water.

[0045] S3b. Scraping off sediment: Before cleaning, adjust the collection bag assembly 34 to change the opening size of the placement bag 345, extend the scraper assembly 33 into the bottom of the sedimentation tank, and use the scraper 333 to scrape off the attachments on the bottom of the tank. The scraped dirt slides along the blade of the scraper 333 into the placement bag 345 for unified collection. When the placement bag 345 is full, it is transferred and emptied, and then cleaning continues.

[0046] Specifically, in S1, when assembling the rod body, if the required distance is longer, the main body length can be increased by nesting multiple extension rods 13; if threaded connection is selected as the connection method between the main rod 11 and the extension rod 13, the overall length can be fine-tuned by rotating the extension rod 13 during the salvage process, and auxiliary gripping components can be provided on the rod bodies of the main rod 11 and the extension rod 13 to prevent slipping.

[0047] In S3a, before salvaging, the wristbands 233 of the two fixed rope groups 23 can be respectively put on the left and right hands of the salvage personnel for easy distinction. During salvage, if a certain set of fixed rope groups 23 needs to be tightened, the extension rope 232 can be wrapped around the corresponding hand to shorten the length of the extension rope 232 until the net bag 22 or the frame 21 is pulled.

[0048] In S3b, in order to facilitate scraping, the scraper 333 needs to have a certain inclination angle when installed, and the placement bag 345 can be a disposable detachable setting, that is, after it is filled once, the seal is removed and another placement bag 345 is replaced to continue cleaning, avoiding the cleaning of the placement bag 345. Of course, the placement bag 345 can be used continuously until it is damaged and replaced to save costs.
