Description

Technical Field

[0001] This utility model belongs to the field of slag scraping and slag discharge technology for inlet troughs, specifically relating to a slag scraping and slag discharge weir gate for a sedimentation tank with cyclic inlet and cyclic outlet. Background Technology

[0002] Weekly inlet and outlet sedimentation tanks are essential structures in municipal wastewater treatment plants. The inlet channel is typically designed with a variable cross-section. At the end of the inlet channel, a large amount of scum accumulates. To prevent scum from entering the sedimentation tank and to ensure the effective use of the inlet channel, a scum discharge weir is usually installed at the end of the inlet channel. The scum discharge weir is opened periodically to remove scum from the inlet channel.

[0003] However, in actual operation, a large amount of scum floats on the surface of the inlet tank, even at the end and throughout the entire tank. When the scum hardens to a certain extent, its fluidity decreases, making it difficult to remove. Over time, it will occupy the water distribution space of the inlet tank and affect the uniformity of water distribution. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a slag scraping and slag discharge weir for the inlet trough of a circumferential inlet and outlet sedimentation tank. This slag scraping and slag discharge weir aims to solve the technical problem that, under existing technologies, when floating slag clumps to a certain extent, its fluidity decreases, leading to difficulties in removal, occupying the water distribution space of the inlet trough, and affecting the uniformity of water distribution.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides a slag scraping and slag discharge weir gate for the inlet trough of a circumferential inlet and outlet sedimentation tank. The slag scraping and slag discharge weir gate for the inlet trough of a circumferential inlet and outlet sedimentation tank includes an inlet trough body and a weir gate body installed in the inlet trough body. Both sides of the top surface of the inlet trough body are rotatably mounted with lead screws, and the side wall of the inlet trough body is rotatably mounted with a rotating shaft through a sealed bearing. Multiple blades are installed at one end of the rotating shaft that extends into the inlet trough body. A scraper that is tightly connected to the inner wall of the inlet trough body is threaded between the two lead screws, and the two lead screws rotate synchronously through a meshing mechanism.

[0008] When using this technical solution, lead screws are installed on both sides of the top surface of the main body of the inlet tank. After the scraper motor is started, the two lead screws rotate simultaneously through the second synchronous pulley and the second synchronous belt. During the rotation, the scraper scrapes off the scum that has hardened on the inner wall of the main body of the inlet tank. The scum removal motor drives the first synchronous pulley and the first synchronous belt to drive the rotating shaft and blades to rotate. The blades push the scum that has been scraped off and is suspended on the water surface toward the top of the weir gate plate for discharge. This facilitates the cleaning of the hardened scum on the inner wall of the main body of the inlet tank, ensures the cleanliness of the surface of the inlet tank, effectively utilizes the volume of the inlet tank, and achieves efficient and uniform water distribution.

[0009] Preferably, a gate plate is slidably inserted into the bottom end of the gate body, and a dual-purpose manual and electric gate opening and closing machine for driving the gate plate to rise and fall is installed at the top end of the gate body.

[0010] Furthermore, a scraper motor connected to a lead screw is installed at one end of the main body of the water inlet tank, and a support plate is fixed at the top of the main body of the water inlet tank.

[0011] Furthermore, a slag removal motor is fixed to the top of the support plate, and a base is fixed to the bottom of the slag removal motor.

[0012] Furthermore, bolts are installed on the base, and the bottom end of the bolts is threaded into the support plate.

[0013] Furthermore, a first synchronous pulley is fixedly sleeved on both the shaft and the rotating shaft of the slag removal motor, and a first synchronous belt is sleeved and installed between the two first synchronous pulleys.

[0014] Furthermore, the meshing mechanism includes a second synchronous pulley fixedly sleeved on two lead screws and a second synchronous belt disposed between the two second synchronous pulleys, with both ends of the second synchronous belt meshing with the two second synchronous pulleys respectively.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention features lead screws on both sides of the top surface of the main body of the inlet tank. After the scraping motor starts, the two lead screws rotate simultaneously via the second synchronous pulley and the second synchronous belt. During the rotation, the scraper scrapes off the scum that has hardened on the inner wall of the inlet tank. The scum removal motor drives the first synchronous pulley and the first synchronous belt to drive the rotating shaft and blades to rotate. The blades push the scum that has been scraped off and is suspended on the water surface toward the top of the weir gate and discharge it. This facilitates the cleaning of the hardened scum on the inner wall of the inlet tank, ensures the cleanliness of the inlet tank surface, effectively utilizes the volume of the inlet tank, and achieves efficient and uniform water distribution.

One end of the rotating shaft 3 that extends into the inlet trough body 1 is equipped with multiple blades 9. The two screw rods 2 are threadedly connected to a scraper 4 that is tightly connected to the inner wall of the inlet trough body 1, and the two screw rods 2 rotate synchronously through a meshing mechanism.

[0026] The bottom end of the weir gate body 6 is slidably connected to the weir gate plate 8, and the top end of the weir gate body 6 is equipped with a hand-operated and electric weir gate hoist 5 for driving the weir gate plate 8 to rise and fall.

[0027] like Figure 3 and Figure 4 As shown, bolts 15 are installed on the base 11, and the bottom end of bolts 15 is threaded into the support plate 10.

The two ends of the second synchronous belt 16 are respectively meshed with the two second synchronous pulleys 17. After the slag removal motor 7 is started, the two lead screws 2 rotate simultaneously through the second synchronous pulleys 17 and the second synchronous belt 16.

After the slag scraping motor 7 starts, the two lead screws 2 rotate simultaneously through the second synchronous wheel 17 and the second synchronous belt 16. During the rotation, the scraper 4 scrapes off the scum that has hardened on the inner wall of the main body of the inlet tank 1. The slag removal motor 12 drives the first synchronous wheel 14 and the first synchronous belt 13 to drive the rotating shaft 3 and the blades 9 to rotate.
