Description

Technical Field

[0001] This utility model relates to a sludge scraper and is situated in the technical field of wastewater treatment equipment. Background Technology

[0002] In wastewater treatment, wastewater is discharged into sedimentation tanks for settling. During this process, a large amount of sludge accumulates at the bottom of the sedimentation tank, which is typically cleaned using a sludge scraper. However, traditional sludge scrapers have some significant limitations, leading to the following problems: 1. During scraping, some of the sludge scraped off floats on the surface of the sedimentation tank. When sampling the sedimentation tank using monitoring equipment, this floating sludge can affect the measured parameters or clog the monitoring equipment's pipelines. 2. Due to the low flow rate of wastewater in the sedimentation tank and its high content of nitrogen, phosphorus, and other substances, algae can proliferate in the sedimentation tank under suitable seasons, with appropriate water temperatures and ample sunlight. This affects the sedimentation effect and deteriorates the water quality. If not treated promptly, the algae will adhere to the sludge scraper, reducing its efficiency. Summary of the Invention

[0003] The purpose of this invention is to design a spray device that can remove floating mud clumps and algae from sedimentation tanks.

[0004] This utility model includes a support platform with a rotating wheel, and a spraying mechanism is provided on the support platform. The spraying mechanism includes a water pump installed on the support platform, the water pump inlet being connected to an inlet pipe that extends downwards from the support platform; the water pump outlet being connected to an outlet pipe that is connected to a spraying pipe, the spraying pipe being provided on the support platform and extending along the length of the support platform, and a set of nozzles being provided on the spraying pipe along its length.

[0005] Furthermore, a dosing tank with a dosing port is fixed on the support platform, and the outlet of the dosing tank is connected to the upper part of the water inlet pipe through a solenoid valve.

[0006] Furthermore, a set of connecting frames is provided on one side of the support platform along its length, with the lower end of each connecting frame protruding towards one side of the support platform, and the spray pipe is installed at the lower part of the connecting frame.

[0007] Furthermore, the support platform has a guardrail, and the upper part of each connecting frame is connected to the upper rail of the guardrail to form its connecting part. Two connecting rods connected to both ends of the connecting part are inclined to the outside of the support platform and connected to each other at the lower end, forming an included angle between the two connecting rods. The spray pipe is located between the two connecting rods.

[0008] Furthermore, the spray pipe is positioned on a side of a radius of the supporting platform.

[0009] This invention features a spraying mechanism that uses a water pump to draw water from the sedimentation tank and sprays it through nozzles to disperse the floating sludge clumps on the surface, causing them to settle to the bottom of the sedimentation tank and preventing them from affecting the monitoring indicators of the sedimentation tank. The chemical dosing tank in this invention also sprays an algae-killing agent into the sedimentation tank via a solenoid valve during the sludge scraping process, preventing algae growth within the sedimentation tank.

[0017] by Figure 1 The diagram shows the up, down, left, right, front, and back directions in this embodiment.

[0018] As shown in the figure, this embodiment includes a support platform 1 with a guardrail on top. Rotary wheels 2 are installed at the lower parts of both the left and right ends of the support platform 1. During use, the rotary wheels 2 at both ends are driven by a motor, controlling the support platform 1 to rotate around its center. A main shaft 3 is located at the lower center of the support platform 1, and is fixedly connected to the support platform 1. The main shaft 3 rotates with the support platform 1, driving the scraping component below to perform the scraping process. The driving method of the rotary wheels 2 and the scraping component below the main shaft 3 are existing technologies and will not be described in detail here.

[0019] A spraying mechanism 4 is installed on the support platform 1. The spraying mechanism 4 includes a water pump 5, which is fixedly installed on the upper end of the support platform 1. A water inlet pipe 6 is installed on the left side of the water pump 5. The water inlet pipe 6 is T-shaped, with its right end connected to the water inlet of the water pump 5 and fixed by a flange. Its lower end extends downward through the support platform 1 into the sedimentation tank. When in use, the water pump 5 can pump water from the sedimentation tank through the water inlet pipe 6. A dosing tank 11 is installed above the water inlet pipe 6. The dosing tank 11 is fixedly installed on the upper end of the support platform 1. A dosing port 12 is installed at its upper end, which can add chemicals into the dosing tank 11. The liquid outlet at the lower end of the dosing tank 11 is connected to the water inlet pipe 6. A solenoid valve 13 is installed at the connection between the dosing tank 11 and the water inlet pipe 6. The two components are fixed by the solenoid valve 13, which can realize remote control of the opening and closing of the liquid outlet of the dosing tank 11.

[0020] A water outlet pipe 7 is connected to the outlet of the water pump 5 via a flange. The water outlet pipe 7 extends downwards after passing through the water pump 5, then passes through the support platform 1 and extends forward. A spray pipe 8 is connected to the front end of the water outlet pipe 7, extending along the length of the support platform 1 and positioned on a side of one radius of the support platform 1. A set of spray nozzles 9 is located below the spray pipe 8. In this embodiment, the spray nozzles 9 are positioned along the length of the spray pipe 8 and are used to spray the water flow drawn into the spray pipe 8 by the water pump 5. In this embodiment, the distance from the right-side rotating wheel 2 to the main shaft 3 is the side length of one radius of the support platform 1. A set of connecting frames 10 is provided along the length of the right side of the support platform 1. In this embodiment, three connecting frames 10 are provided. The upper part of each connecting frame 10 spans the upper railing of the guardrail of the support platform 1 to form its spanning part. The lower part consists of two connecting rods, which are fixed to the two ends of the spanning part by welding. The lower parts of the two connecting rods are inclined towards the front of the support platform 1, and the lower ends of the two connecting rods are connected to each other. The welding makes the two connecting rods form an included angle, which protrudes towards the front of the support platform 1. The spray pipe 8 passes through the included angle at the lower end of each connecting frame 10 and is supported by each connecting frame 10, so that the spray head 9 is away from the support platform 1 and the support platform 1 does not affect the spraying effect. In this embodiment, the included angle at the lower end of each connecting frame 10 is rounded to reduce stress concentration.

[0021] In use, this invention first activates each rotating wheel 2, and the support platform 1 rotates around its center to perform a sludge scraping process. At the same time, the spraying mechanism 4 rotates with the support platform 1. During the rotation, the water pump 5 is activated, drawing water from the sedimentation tank through the inlet pipe 6. The water flows through the outlet pipe 7 and is transported to the spray pipe 8. The spray is then applied to the sedimentation tank through the nozzles 9 that move with the support platform 1, dispersing the sludge floating on the surface of the sedimentation tank and causing it to settle to the bottom of the sedimentation tank, thus avoiding affecting the test indicators of the sedimentation tank. When it is necessary to clean algae in the sedimentation tank, the solenoid valve 13 is opened during the spraying process. The chemicals in the dosing tank 11 are drawn into the spray pipe 8 by the water pump 5 and sprayed into the sedimentation tank through the nozzles 9 to clean the algae.
