Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a pushable sludge scraping device for sedimentation tanks. Background Technology

[0002] In the wastewater treatment process, sedimentation tanks are one of the key treatment units. Their function is to settle suspended particles in wastewater and achieve solid-liquid separation. The sludge scraper is an important piece of equipment in the sedimentation tank, responsible for scraping the sludge settled at the bottom of the tank and pushing it to the sludge discharge port for subsequent treatment.

[0003] A search revealed a sedimentation tank inner wall scraping mechanism with authorization announcement number CN216755488U. The mechanism includes a sedimentation tank, with a sludge discharge pipe penetrating the bottom and a support frame fixedly connected to the top. A first motor is fixedly connected to the top of the support frame. The beneficial effects of this invention are that, during operation, two scraping devices, connected by a scraping frame, a limiting seat, a shovel blade, a mounting frame, and a scraping plate, can simultaneously scrape the inner and bottom walls of the sedimentation tank. The shovel blade, through a movable connection, allows it to be inserted laterally into the sludge, and the sludge flow port allows the scraped sludge to pass through, thereby reducing scraping resistance. The structure is reasonable and provides better scraping effect.

[0004] In the process of implementing the above solution, the following problems were found in the existing technology that have not been well resolved: In the existing technology, when the sludge on the inner wall of the sedimentation tank is scraped by the sludge scraper, the sludge is directly discharged through the sludge discharge pipe. However, since there is no good sludge pushing component in the sludge discharge pipe, the sludge will accumulate in the sludge discharge pipe as it flows out naturally, thus causing the pipe to be blocked. Therefore, it is urgent to design a pushable sedimentation tank scraping device to solve the above problems. Utility Model Content

The sludge scraping assembly 6 includes a sludge scraping frame 601 fixedly installed on one side of the rotating drum 8, and the sludge scraping frame 601 is attached to the inner bottom wall of the tank body 1. The sludge scraping frame 601 is composed of a square frame and a semi-circular frame. One end of the sludge scraping frame 601 has a third mounting hole on one side of the rotating drum 8.

At this time, the first spiral blade 603 on the first drive shaft 602 rotates under the meshing transmission of the bevel ring 605 and the first bevel gear 604, which facilitates the sludge to be transported to the sludge discharge trough and realizes the sludge scraping performance of the sedimentation tank.

[0036] Component 13 is introduced and is mounted on the sludge discharge trough and the base 11;

[0037] The ejector assembly 13 includes an outlet 1301 located on one side of the top of the base 11, and a sludge discharge pipe 1302 extending out of the sludge discharge trough is fixed to one side of the outlet 1301.

A second drive shaft 1306 is rotatably connected to the inner wall of the first mounting hole via a sealed bearing. A second spiral blade 1307 is mounted on the outer wall of the second drive shaft 1306, fitting against the bottom of the inner wall of the outlet 1301 and the inner wall of the sludge discharge pipe 1302. A transmission assembly is provided at one end of the second drive shaft 1306.

A rotating rod 1308 is rotatably connected to the inner wall of the hole via a sealed bearing. The top of the rotating rod 1308 is fixedly connected to the top inner wall of the rotating drum 8. A second bevel gear 1305 is fixedly installed at the bottom of the rotating rod 1308 and one end of the second drive shaft 1306. The two second bevel gears 1305 mesh with each other. A valve 1303 is installed at one end of the sludge discharge pipe 1302. When the rotating drum 8 rotates, it drives the rotating rod 1308 to rotate synchronously. The two meshing second bevel gears 1305 drive the second drive shaft 1306 and the second spiral blade 1307 to rotate, which facilitates the sludge to be pushed out from the discharge port 1301 through the sludge discharge pipe 1302. This realizes the function of automatic sludge pushing and discharge, avoids the problem of pipe blockage when sludge is discharged, and reduces manual operation costs and labor intensity.

[0038] Specifically, the bottom end of the sludge shovel frame 601 is provided with a drop opening 606, and the drop opening 606 is located above the sludge discharge trough.

[0041] The working principle of this utility model is as follows: the motor 4 in the drive mechanism drives the drive shaft 9 to rotate, which in turn drives the rotating drum 8 to rotate around the fixed drum 12. When the rotating drum 8 rotates, the sludge shovel frame 601 fixed on one side moves accordingly. The inclined blade surface at the bottom of the sludge shovel frame 601 is in contact with the inner wall of the bottom of the pool body 1 to shovel up the sludge. At the same time, the first spiral blade 603 on the first drive shaft 602 rotates under the meshing transmission of the bevel ring 605 and the first bevel gear 604, and transports the sludge in the sludge shovel frame 601 to the direction of the sludge discharge trough through the drop port 606. Moreover, the first scraper 5 at the top of the sludge shovel frame 601 is in contact with the inner wall of the circumference of the pool body 1, and the second scraper 7 at the bottom is in contact with the inner wall of the sludge discharge trough and the top surface of the base 11, which can thoroughly clean the pool wall and the sludge discharge trough.

[0042] When the rotating drum 8 rotates, the rotating rod 1308, which is fixedly connected to its top inner wall, rotates synchronously. It works with two meshing second bevel gears 1305 to drive the second transmission shaft 1306 to rotate, thereby causing the second spiral blade 1307 to rotate in the discharge outlet 1301 and the sludge discharge pipe 1302, pushing the sludge out from the discharge outlet 1301 through the sludge discharge pipe 1302. The valve 1303 at one end of the sludge discharge pipe 1302 can control the sludge discharge speed and flow rate.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
