Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a device for unclogging an aerated grit chamber. Background Technology

[0002] Aerated grit chambers are pretreatment facilities used in wastewater treatment to remove inorganic particles (such as sand and cinders) with a higher specific gravity from wastewater. They use aeration to create swirling currents in the wastewater, thus separating sand particles from organic matter.

[0003] Existing aerated grit chambers require regular flushing and maintenance after a period of use, and the silt and water generated during flushing are discharged through the sand discharge pipe. However, due to the large amount of sand carried in the flushing water and the limited power and speed when discharging it, the sand discharge pipe is prone to blockage. Therefore, we have made an improvement and proposed an aerated grit chamber unblocking device. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0031] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] like Figure 1-5 As shown, this embodiment proposes an aerated grit chamber dredging device, including an aerated grit chamber body 1 and a grit discharge pipe 2. The output end of the aerated grit chamber body 1 is fixedly connected to a grit inlet 3, and the grit inlet 3 is connected to the input end of the grit discharge pipe 2. A dredging mechanism 4 and a plugging mechanism 5 are provided on the outside of the grit discharge pipe 2.

[0034] The unblocking mechanism 4 includes a high-pressure water gun 401, a water pipe 402, a nozzle 403, a motor 404, a sleeve 405, a connecting ring 406, a fan blade 407, and a water outlet 408.

[0035] The high-pressure water gun 401 is detachably connected to the sand discharge pipe 2. The water pipe 402 is set at the input end of the high-pressure water gun 401. The nozzle 403 is fixedly connected to the output end of the high-pressure water gun 401. The motor 404 is fixedly installed on the surface of the nozzle 403. The sleeve 405 is fixedly connected to the output shaft end of the motor 404. The connecting ring 406 is rotatably connected to one side of the sleeve 405. The fan blade 407 is set on the outer wall of the sleeve 405. The water outlet 408 is opened on the surface of the sleeve 405.

[0036] like Figure 5 As shown, the output shaft of the energized motor 404 drives the sleeve 405 to rotate. By energizing the motor 404, the output shaft of the energized motor 404 drives the sleeve 405 to rotate, and the rotating sleeve 405 drives the fan blade 407 and the water outlet 408 to rotate in a circular motion.

[0037] like Figure 5 As shown, the high-pressure water gun 401 in the energized state is used to supply water to the inside of the sleeve 405 through the nozzle 403. By energizing the high-pressure water gun 401, the energized high-pressure water gun 401 supplies water to the inside of the sleeve 405 through the nozzle 403.

[0038] like Figure 5 As shown, the nozzle 403 is connected to the inside of the sleeve 405 via the connecting ring 406. Water is supplied to the high-pressure water gun 401 through the water pipe 402 via an external water tank, and the water flows into the sleeve 405 through the connecting ring 406.

[0039] like Figure 4 As shown, the plugging mechanism 5 includes a sand outlet pipe 501, a slot 502, and a plug 503;

[0040] The sand discharge pipe 501 is fixedly connected to the output end of the sand discharge pipe 2. The slot 502 is opened on one side of the sand discharge pipe 2, and the plug 503 is threadedly connected to the slot 502. When the plug 503 is removed from the slot 502, the plug 503 in the removed state opens the slot 502. Then, the unblocking mechanism 4 is placed inside the sand discharge pipe 2, and the external unwinding device unwinds the unblocking mechanism 4, allowing the unblocking mechanism 4 to move inside the sand discharge pipe 2.

[0041] like Figure 4 As shown, the plug 503 in the installed state is used to seal the slot 502, and the plug 503 in the disassembled state is used to open the slot 502. By opening the slot 502 with the plug 503 in the disassembled state, it is easier to place the entire unblocking mechanism 4 inside the sand discharge pipe 2.

[0042] like Figure 4As shown, the sand outlet pipe 501 is used to discharge the silt and sand accumulated inside the sand discharge pipe 2. The rotating sleeve 405 sprays water out through the water outlet 408 to flush the silt and sand accumulated inside the sand discharge pipe 2, and the rotating fan blade 407 scrapes away the silt and sand accumulated inside the sand discharge pipe 2. This structure facilitates the unblocking of the silt and sand accumulated inside the sand discharge pipe 2, and the removed silt and sand are then discharged to the outside of the sand discharge pipe 2 through the sand outlet pipe 501.

[0043] Specifically, when using this aerated grit chamber dredging device: when it is necessary to dredge the silt and sand accumulated inside the grit discharge pipe 2, firstly, remove the plug 503 from the slot 502. The plug 503 in the removed state opens the slot 502. Then, place the dredging mechanism 4 inside the grit discharge pipe 2 and let the external unwinding device unwind the dredging mechanism 4. The dredging mechanism 4 moves inside the grit discharge pipe 2. Then, the water pipe 402 supplies water to the high-pressure water gun 401 through the external water tank. Then, connect the high-pressure water gun 401 to power and run it. The high-pressure water gun 401 in the powered state supplies water to the sleeve 405 through the nozzle 403. The water flows into the sleeve 405 through the connecting ring 406.

[0044] Then, the motor 404 is powered on and started, so that the output shaft of the powered motor 404 drives the sleeve 405 to rotate. The rotating sleeve 405 drives the fan blade 407 and the water outlet 408 to rotate in a circle. The rotating sleeve 405 sprays water out through the water outlet 408 to wash away the mud and sand accumulated inside the sand discharge pipe 2. The rotating fan blade 407 scrapes away the mud and sand accumulated inside the sand discharge pipe 2. This structure facilitates the unblocking of the mud and sand accumulated inside the sand discharge pipe 2. The removed mud and sand are then discharged to the outside of the sand discharge pipe 2 through the sand outlet pipe 501.

[0045] All technical features in this embodiment can be freely combined according to actual needs.

[0046] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
