Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a dosing device for wastewater treatment that is easy to adjust. Background Technology

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Currently, wastewater is purified in factory wastewater ponds by adding a certain amount of chemicals. A search revealed existing technology (Publication No.: CN202121296400.3) – an easily adjustable wastewater treatment dosing device. The document describes "pulling the corrugated pipe, inserting both ends of the corrugated pipe into the fixed ring on one side of the connecting pipe, and then rotating the rotating ring to thread the threaded ring and threaded groove. At this point, the fixed ring and rotating ring can be fixed, thereby adjusting the corrugated pipe..." The pipes are fixed to the connecting pipes. Due to the expandable nature of the corrugated pipes, they can be self-adjusted according to the height of the medicine tank, facilitating the adjustment of the connection distance between pipes. Activating the hydraulic rod pushes the casters downwards, causing the connecting blocks to slide along the connecting groove. When the casters reach the desired position, the hydraulic rod lifts the frame, separating the fixing plate from the ground. Pushing the equipment allows it to be moved via the casters, facilitating mobile use. However, existing technologies suffer from difficulties in effectively adjusting the pump's delivery position and dosing range when the medicine tank is located in a wastewater treatment tank for mobile dosing.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1 to 4 As shown, this utility model provides an easily adjustable dosing device for wastewater treatment, including: a dosing cart 1, on the upper surface of which a chemical solution tank 34 is placed.

[0020] The upper inner side of the dosing cart 1 is movably connected to a limiting base column 41. A worm gear transmission assembly 44 is installed on the cylindrical surface of the limiting base column 41. A height adjustment frame 4 is welded to the upper cylindrical surface of the limiting base column 41. A screw lifting mechanism 42 is installed inside the height adjustment frame 4. The screw lifting mechanism 42 is connected to the drug delivery cylinder 2 through a drive block 45. A spiral blade 22 is axially connected to the inner side of the drug delivery cylinder 2. A spray plate 3 is distributed at the upper end of the drug delivery cylinder 2. The lower end of the spray plate 3 is connected to the drive block 45 through a connecting bracket 46. A small motor 35 is axially connected to the front side of the spray plate 3. The spray plate 3 is connected to the drug tank 34 through an infusion hose 32.

[0021] First, based on the current water quality monitoring in the sewage treatment tank, select the type of solid or liquid agent to add. Push the dosing cart 1 to the side of the sewage treatment tank. The screw lifting mechanism 42 drives the agent delivery cylinder 2 and the spray plate 3 to move upward to a suitable height. Then, control the spiral blades 22 in the agent delivery cylinder 2 to deliver the agent in the solid agent cylinder 23 into the tank. Then, drive the small motor 35 to rotate and tilt the spray plate 3 to the moving angle, so that the metering pump 33 delivers the liquid from the liquid tank 34 into the spray plate 3. The liquid is then sprayed outward through the nozzles 31 of the spray plate 3, so that the tilted nozzles 31 spray out multiple parabolic lines, which facilitates the dispersion of the liquid into the sewage treatment tank.

[0022] In this embodiment, a control cabinet 11 is fixed on the upper surface of the dosing cart 1, and a control panel is provided on the upper surface of the control cabinet 11; and the control cabinet 11 is located on the rear side of the medicine tank 34.

[0023] As a preferred implementation, the control cabinet 11 is equipped with a controller and a storage battery. The controller controls the electrical equipment designed for the dosing process, and the storage battery provides power for the operation of the mechanical mechanism, making it convenient to operate the agent delivery cylinder 2 and the spray plate 3 to add treatment agents to the surface of the sewage tank.

[0024] In this embodiment, a solid drug cylinder 23 is provided on the right side of the upper end face of the drug delivery cylinder 2, and a discharge port 21 is provided on the lower end face of the drug delivery cylinder 2.

[0025] In a preferred embodiment, the solid agent in the solid agent cylinder 23 falls into the agent conveying cylinder 2, and the agent is conveyed to the discharge port 21 and discharged into the sewage treatment tank by the spiral blades 22 in the agent conveying cylinder 2.

[0026] In this embodiment, nozzles 31 are equidistantly installed on the left side of the spray plate 3, and a metering pump 33 is connected to the surface of the infusion hose 32; the metering pump 33 is fixed at the front end of the drug dosing cart 1. The lower end of the spray plate 3 is connected to the inner side of the connecting bracket 46 by a movable shaft, and the drug delivery cylinder 2 and the height adjustment frame 4 are vertically distributed.

[0027] In a preferred embodiment, the metering pump 33 delivers a certain amount of the agent from the medicine tank 34 to the nozzle 31 of the spray plate 3 for spraying. The small motor 35, which is axially connected to the front side of the spray plate 3, facilitates the rotation of the small motor 35, allowing the nozzle 31 of the spray plate 3 to spray a wider range and the agent to be added to the sewage treatment tank in a more dispersed manner.

[0028] In this embodiment, a connecting bracket 46 is welded to the left side of the drive block 45; and a medicine delivery cylinder 2 is inserted and fixed to the inner side of the connecting bracket 46, and a small motor 35 is fixed to the front surface of the connecting bracket 46. The worm gear transmission assembly 44 is connected to an adjusting column 43 through a worm; and the adjusting column 43 is located at the distance between the height adjustment frame 4 and the medicine tank 34.

[0029] As a preferred implementation, the drive block 45 facilitates the conversion of the rotational motion of the screw lifting mechanism 42 into linear motion, thereby driving the agent conveying cylinder 2 and the spray plate 3 to move up and down, achieving the effect of adjusting the dosing height of the sewage treatment agent. The worm gear transmission assembly 44 mainly consists of a worm gear and a worm. By manually rotating the adjusting column 43, the worm gear transmission assembly 44 is driven to mesh and rotate, thereby driving the limiting bottom column 41 to rotate at a certain angle, adjusting the feeding position of the agent conveying cylinder 2 and the spray plate 3. This allows for quick adjustment of the dosing position of the dosing device as it moves with the dosing trolley, ensuring that the dosing device accurately adds the sewage treatment agent into the sewage treatment tank, and reducing the labor intensity of manual dosing.

[0030] This utility model's easily adjustable wastewater treatment dosing device effectively solves the problem in existing technologies where the pump's delivery position and dosing range are difficult to adjust when the dosing tank is located in the wastewater treatment tank and the device is moved around. It allows for quick adjustment of the dosing position as the device moves with the dosing cart, ensuring that the dosing device accurately delivers wastewater treatment chemicals into the wastewater treatment tank. This reduces the labor intensity of manual dosing, improves the convenience of mobile dosing devices, and is suitable for easily adjustable wastewater treatment dosing devices.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
