Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment, and in particular to a multifunctional sludge scraper for sewage treatment tanks. Background Technology

[0002] Sludge scrapers are key equipment in sedimentation tanks (such as radial flow, horizontal flow, or vertical flow sedimentation tanks) of wastewater treatment plants. They use mechanical devices to scrape the sludge settled at the bottom of the tank to the sludge discharge port, preventing sludge accumulation from affecting water quality and treatment efficiency. During their use, they mainly use rotating or reciprocating scrapers to scrape the sludge towards the discharge port. Early sludge scrapers relied on manual operation, which was inefficient and prone to safety accidents. Therefore, sludge scrapers for wastewater treatment tanks have attracted much attention.

[0003] Existing sludge scrapers for wastewater treatment ponds are all one-piece molded machines. The scraper arm is fixed to a track around the pond through the machine body, and the drive device moves along the track. As a result, they can only clean the bottom of the pond on the same plane. When the bottom of the pond is uneven, they cannot effectively scrape the sludge from the uneven areas, thus affecting their overall scope of use and performance. Therefore, this application provides a multi-functional sludge scraper for wastewater treatment ponds to meet the needs. Utility Model Content

[0004] The purpose of this application is to provide a multifunctional sludge scraper for sewage treatment ponds, which solves the problem that the existing technology cannot adapt to different sewage treatment ponds, and achieves the goal of improving the overall flexibility and adaptability of use.

[0005] To achieve the above objectives, this application provides the following technical solution: a multifunctional sludge scraper for sewage treatment ponds, comprising a transmission rack and a drive motor. The transmission rack is spliced ​​together by a splicing assembly. The output end of the drive motor is fixedly connected to a drive shaft, and a drive gear is meshed with the top of the transmission rack. The drive shaft is inserted into the drive gear, and the drive motor drives the drive gear to rotate through the drive shaft. Each of the two transmission racks has a mounting shaft on one side opposite to the other, and a mounting sleeve is sleeved around the periphery of the mounting shaft. Multiple elastic push rods are connected to the mounting sleeves through multiple mounting rings, and a cleaning scraper is fixedly connected to the bottom end of each elastic push rod. The multiple cleaning scrapers are independently controlled by the elastic push rods connected to them.

[0006] Preferably, the splicing assembly includes a splicing cavity formed on the side wall of the transmission rack, and the interior of the splicing cavity is connected to the same lower pressure plate by multiple compression springs. The other side wall of the transmission rack is fixedly connected to a splicing plate, and the splicing plate can be inserted into the interior of the splicing cavity.

[0007] Preferably, the top of the splicing plate is provided with multiple locking grooves, and the bottom of the lower pressure plate is fixedly connected with a locking plate, the lower pressure plate and the locking plate being compatible.

[0008] Preferably, the splicing cavity has a guide groove inside, and the side wall of the splicing plate is fixedly connected to a guide member, which is slidably connected inside the guide groove.

[0009] Preferably, the splicing cavity has an installation cavity inside, and a buffer plate is fixed inside the installation cavity, with the splicing plate in contact with the buffer plate.

[0010] Preferably, a fixing plate is fixedly connected inside the cleaning scraper, and a connecting scraper is provided between the two cleaning scrapers. Both sides of the connecting scraper are fixedly connected to fixing members, and the fixing members are engaged with the fixing plate.

[0011] Preferably, the side wall of the transmission rack is provided with a mounting hole, and an internal threaded sleeve is fixedly connected inside the mounting hole. Both ends of the mounting shaft are fixedly connected with threaded columns, and the internal threaded sleeve and the threaded columns are compatible. The side wall of the mounting sleeve is provided with a placement groove, and a connecting band is fixedly connected to the mounting shaft. The connecting band is snapped into the inside of the placement groove.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model has a reasonable structure. It is equipped with multiple cleaning scrapers that are independently controlled by elastic push rods connected to them. When the bottom of the sewage treatment tank is uneven, the uneven bottom can obstruct the cleaning scrapers to a certain extent, so that the cleaning scrapers are subjected to force and the force is transmitted to the elastic push rods. The elastic push rods are deformed and shortened under the force, which in turn drives the cleaning scrapers to move upward. Thus, the cleaning scrapers can perform autonomous scraping operations according to the specific conditions of the bottom of the sewage treatment tank, improving the overall flexibility and convenience of its use and reducing the generation of cleaning dead corners.

[0014] 2. In this utility model, by setting an inner threaded sleeve and a threaded post, and selecting an installation shaft of appropriate size, the threaded post at the free end of the installation shaft is aligned with the fixing part on the transmission rack, so that the installation shaft can be directly screwed, so that the installation shaft is threadedly connected to the inner threaded sleeve through the threaded post. After the installation shaft is installed, the connecting belt can be pulled directly, so that the connecting belt is deformed by force and locked inside the placement groove, thereby limiting the position of the installation sleeve and ensuring the stability of the installation sleeve during use.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0027] The following is combined with Figure 1-4 The embodiments shown illustrate the technical solution of this utility model:

[0028] The device includes a transmission rack 1 and a drive motor 2. The transmission rack 1 is spliced ​​together by splicing components. The output end of the drive motor 2 is fixedly connected to a drive shaft 3, and the top of the transmission rack 1 is meshed with a drive gear 4. The drive shaft 3 is inserted into the drive gear 4, and the drive motor 2 drives the drive gear 4 to rotate through the drive shaft 3. Each of the two transmission racks 1 has a mounting shaft 5 on one side opposite to the other, and a mounting sleeve 6 is sleeved around the periphery of the mounting shaft 5. Multiple elastic push rods 8 are connected to the mounting sleeve 6 through multiple mounting rings 7, and a cleaning scraper 9 is fixedly connected to the bottom end of the elastic push rod 8. The multiple cleaning scrapers 9 are independently controlled by the elastic push rods 8 connected to them.

[0029] During its use, multiple transmission racks 1 can be directly selected and automatically spliced ​​together using a splicing assembly, so that the length of the spliced ​​transmission racks 1 is the same as that of the sewage treatment tank. Two spliced ​​transmission racks 1 are placed on both sides of the sewage treatment tank, and the two drive gears 4 mesh with the spliced ​​transmission racks 1. Thus, the drive motor 2 can be directly controlled by an external controller, allowing the drive motor 2 to autonomously drive the drive gears 4 to move via the drive shaft 3. When the drive gears 4 are subjected to force and move, the drive gears 4 can transmit the moving force through the mounting shaft 5 and the mounting... The force of the sleeve 6 is transmitted to the elastic push rod 8 and the cleaning scraper 9, allowing the cleaning scraper 9 to clean the bottom of the sewage treatment tank under its force. When the bottom of the sewage treatment tank is uneven, the uneven bottom can provide some resistance to the cleaning scraper 9, causing the cleaning scraper 9 to be under force and transmitting the force to the elastic push rod 8. The elastic push rod 8 deforms and shortens under the force, which in turn drives the cleaning scraper 9 to move upward. Thus, the cleaning scraper 9 can perform autonomous scraping operations according to the specific conditions of the bottom of the sewage treatment tank, improving its overall flexibility and convenience of use and reducing the generation of cleaning dead corners.

[0030] The splicing assembly includes a splicing cavity 10 formed on the side wall of the transmission rack 1, and the same lower pressure plate 12 is connected inside the splicing cavity 10 through multiple compression springs 11. A splicing plate 13 is fixedly connected to the other side wall of the transmission rack 1, and the splicing plate 13 can be inserted into the inside of the splicing cavity 10.

[0031] During the splicing process, the first transmission rack 1 can be directly pushed, allowing the splicing plate 13 on the side wall of the first transmission rack 1 to be inserted into the splicing cavity 10 of the second transmission rack 1 under its force. At this time, due to the size of the splicing plate 13 itself, the insertion force can be effectively converted into a thrust force acting on the lower pressure plate 12, causing the lower pressure plate 12 to be stressed and its force to be transmitted to the splicing plate 13, causing the compression spring 11 to deform and shorten, thereby driving the lower pressure plate 12 to move, providing effective space for the installation of the splicing plate 13. After the splicing plate 13 is inserted, the reaction force of the deformation of the compression spring 11 will act on the lower pressure plate 12, causing the lower pressure plate 12 to quickly press down and fix the splicing plate 13, thus quickly completing the installation steps.

[0032] The top of the splicing plate 13 is provided with multiple locking grooves, and the bottom of the lower pressure plate 12 is fixedly connected to the locking plate 14, and the lower pressure plate 12 and the locking plate 14 are compatible.

[0033] During its use, the locking plate 14 can move along with the lower pressure plate 12. When the lower pressure plate 12 is pressed down, it will drive the locking plate 14, so that the locking plate 14 can move along the locking groove and then lock into the inside of the locking groove. At this time, the locking structure between the locking groove and the locking plate 14 will further improve the stability of its overall splicing structure and prevent the possibility of movement during use.

[0034] The splicing cavity 10 has a guide groove 15 inside, and the side wall of the splicing plate 13 is fixedly connected to a guide member 16, which is slidably connected inside the guide groove 15.

[0035] During its assembly and installation, when the lower pressure plate 12 moves, the moving force of the lower pressure plate 12 can be effectively transmitted to the guide member 16, so that the guide member 16 slides along the guide groove 15 under force. At this time, the sliding structure between the guide groove 15 and the guide member 16 can effectively limit the movement trajectory of the lower pressure plate 12, so that it remains stable during use and avoids the possibility of deviation during adjustment.

[0036] The splicing cavity 10 has an installation cavity inside, and a buffer plate 17 is fixed inside the installation cavity, and the splicing plate 13 is in contact with the buffer plate 17.

[0037] During its use, when the splicing plate 13 is forcefully inserted into the splicing cavity 10, the buffer plate 17 can effectively buffer and dampen the impact force of the splicing cavity 10 insertion, thereby ensuring the stability of its overall splicing use.

[0038] The cleaning scraper 9 is internally fixedly connected to a fixing plate 18, and a connecting scraper 19 is provided between the two cleaning scrapers 9. Both sides of the connecting scraper 19 are fixedly connected to fixing parts 20, and the fixing parts 20 are engaged with the fixing plate 18.

[0039] Before use, the connecting scraper 19 can be placed directly between the two cleaning scrapers 9, thereby directly pushing the fixing member 20, causing the fixing member 20 to deform and bend under force. After bending, the fixing member 20 can effectively enter the interior of the cleaning scraper 9, and then it can be released directly. At this time, the fixing member 20 will automatically reset under the action of its own deformation reaction force, thereby engaging with the fixing plate 18. At this time, the engagement structure between the fixing plate 18 and the fixing member 20 will effectively limit the position of the connecting scraper 19, making it stable during use.

[0040] The side wall of the transmission rack 1 is provided with a mounting hole, and an inner threaded sleeve 21 is fixedly connected inside the mounting hole. Both ends of the mounting shaft 5 are fixedly connected with threaded posts 22, and the inner threaded sleeve 21 and the threaded posts 22 are compatible. The side wall of the mounting sleeve 6 is provided with a placement groove 23, and a connecting band 24 is fixedly connected to the mounting shaft 5. The connecting band 24 is snapped into the inside of the placement groove 23.

[0041] Before use, a suitable size mounting shaft 5 can be selected directly. The threaded post 22 at the free end of the mounting shaft 5 is aligned with the fixing part 20 on the transmission rack 1, so that the mounting shaft 5 can be directly screwed, so that the mounting shaft 5 is threadedly connected to the inner threaded sleeve 21 through the threaded post 22. After the mounting shaft 5 is installed, the connecting band 24 can be pulled directly, so that the connecting band 24 is deformed by force and locked inside the placement groove 23, thereby limiting the position of the mounting sleeve 6 and ensuring the stability of the mounting sleeve 6 during use.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
