Description

Technical Field

[0001] The utility model relates to the technical field of secondary sedimentation tank cleaning equipment, in particular to a secondary sedimentation tank outlet tank cleaning device. Background Art

[0002] The outlet trough of the secondary sedimentation tank of the sewage treatment plant is easily soaked in water, and some algae and moss are easily attached to the trough wall, which not only affects the appearance, but also affects the water outlet effect and even interferes with the detection results of online monitoring over time. The current methods for dealing with such attachments are mainly manual brush cleaning and machine flushing. For example, the invention with publication number CN114378078A provides a high-efficiency flushing device for moss on the outlet cofferdam of the secondary sedimentation tank. The operation of the traveling device drives the traveling device to run on the pool surface of the secondary sedimentation tank. The operation of the traveling device drives the whole set of high-pressure flushing components to run. During the operation of the whole set of high-pressure flushing components, the fan-shaped nozzle is driven to move to the outlet cofferdam of the secondary sedimentation tank. Since the high-pressure submersible pump dives below the water surface of the secondary sedimentation tank to supply water to the water supply pipe, the water supply pipe is finally connected to the fan-shaped nozzle. Water is sprayed from the fan-shaped nozzle to flush the moss on the inner wall of the secondary sedimentation tank outlet cofferdam. The universal joint structure can adjust the position and direction of the fan-shaped nozzle. Although this flushing device can reduce the burden on operating personnel and reduce safety risks compared with manual operation, it still has certain disadvantages. It only uses the fan-shaped nozzle to flush at a certain position in the outlet trough, and the flushing range is limited. Although the universal joint structure is used to adjust the direction of the nozzle, manual correction is still required, which is time-consuming and labor-intensive. The flushing force in the middle position of the nozzle water outlet is stronger, while it is weaker on both sides. At the same time, after the universal joint structure adjusts the angle of the nozzle, there is still a risk of turning during the movement of the accompanying vehicle, and the stability is poor. There is also a lack of corresponding flushing at the top positions on both sides of the outlet trough, and the entire outlet trough cannot be fully flushed, and the flushing effect is limited.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0024] Reference Figures 1 to 5 As shown, the utility model provides a secondary sedimentation tank outlet tank cleaning device, comprising:

[0025] A high-pressure submersible pump 2 is arranged on a driving device at the center of the secondary sedimentation tank, and the high-pressure submersible pump 2 extends into the secondary sedimentation tank;

[0026] A first X-axis horizontal pipe 3, which is arranged on a traveling frame above the secondary sedimentation tank and is connected to the outlet of the high-pressure submersible pump 2;

[0027] A second X-axis horizontal pipe 4 is arranged directly above the outlet trough of the second sedimentation tank, and the second X-axis horizontal pipe 4 is connected to the first X-axis horizontal pipe 3. Both ends of the second X-axis horizontal pipe 4 are provided with a first spray gun 5, and the first spray gun 5 includes a V-shaped nozzle 520. The V-shaped nozzle 520 of the first spray gun 5 is aimed at the top of the trough body on both sides of the outlet trough of the second sedimentation tank;

[0028] A first Z-axis vertical pipe 6, one end of which is connected to the middle of the second X-axis horizontal pipe 4, and the other end of which extends into the outlet tank of the second sedimentation tank;

[0029] A Y-axis horizontal tube 7, the middle part of which is connected to the first Z-axis vertical tube 6, and second Z-axis vertical tubes 8 are arranged at both ends of the Y-axis horizontal tube 7. Multiple groups of second spray guns 9 are evenly arranged along the axis of the second Z-axis vertical tube 8, and the second spray gun 9 also includes a V-shaped nozzle 520. The number of a single group of second spray guns 9 is two and they are symmetrically arranged. The second spray gun 9 forms a certain angle with the second Z-axis vertical tube 8, and the second spray gun 9 forms a certain angle with the Y-axis horizontal tube 7, and the V-shaped nozzle 520 of the second spray gun 9 is downward and points to the wall of the outlet trough of the second sedimentation tank.

[0030] In this secondary sedimentation tank outlet trough cleaning device, the high-pressure submersible pump 2 directly draws water from the secondary sedimentation tank, and the first spray guns 5 at both ends of the second X-axis horizontal pipe 4 are used to flush the top of the trough body on both sides of the secondary sedimentation tank outlet trough. The pumped water is transported from the first Z-axis vertical pipe 6 to the Y-axis horizontal pipe 7 and then divided into two and sprayed by multiple groups of second spray guns 9. The second spray guns 9 are aimed obliquely downward at the inner wall of the secondary sedimentation tank outlet trough. The design of the V-shaped nozzle 520 can not only enhance the water pressure, but also multiple second spray guns 9 are evenly distributed along the second Z-axis vertical pipe 8, ensuring that the entire height direction of the trough wall can be strongly flushed. The first spray gun 5 and the second spray gun 9 can stably and comprehensively flush the water outlet trough while always moving in the tangential direction of the rotation of the traveling frame, which greatly improves the flushing efficiency and shortens the flushing time. No manual adjustment is required, which greatly saves manpower and material resources.

[0031] Specifically, in the present embodiment, the second X-axis horizontal tube 4 and the first X-axis horizontal tube 3 can be integrally formed or connected by flanges. The first spray gun 5 is arranged at both ends of the second X-axis horizontal tube 4 in the vertical direction. Furthermore, in order to enhance the flushing force of the first spray gun 5, the V-shaped nozzle 520 of the first spray gun 5 can be moved closer to the top of the trough body of the water outlet trough, and the first spray gun 5 can form a certain angle with the second X-axis horizontal tube 4 and face the tangent direction of the rotation of the carriage frame; the second spray gun 9 can be arranged in three groups or more, and two of each group are arranged on both sides of the second Z-axis vertical tube 8 respectively. More second Z-axis vertical tubes 8 can be arranged to improve the flushing efficiency of the second spray gun 9; the pipe fittings are rigidly connected, and the stability between the pipe fittings can be enhanced by ribs and connecting plates; such as Figure 2 As shown, the two second spray guns 9 of each group are respectively directed downward toward the two side walls of the water outlet trough, as shown in FIG. Figure 3 As shown, the two second spray guns 9 in each group are facing the tangential direction of the rotation of the traveling frame so as to shorten the distance between them and the groove wall to increase the flushing force; the opening direction of the V-shaped nozzle 520 is always forward, and the edges of the diffused water columns sprayed by the V-shaped nozzles 520 of multiple second spray guns 9 overlap to ensure the comprehensive flushing of the groove wall along the height direction. Furthermore, multiple groups of the first spray guns 5 can also be set along the Y-axis direction. When only one group is set, the first spray gun 5 can lag behind the second spray gun 9 in the forward direction.

[0032] Furthermore, an external power supply is also included, and the external power supply includes a power switch, and the power switch is connected to the high-pressure submersible pump 2.

[0033] Specifically, the crane drive device in the center of the secondary sedimentation tank draws power from the outside through a power supply slide line, the high-pressure water pump can draw power directly from the power supply slide line, and the power switch can be set on the fixed bridge above the secondary sedimentation tank or in the control room to cooperate with the controller for intelligent control.

[0034] Furthermore, the first spray gun 5 and the second spray gun 9 both include a water outlet pipe 510 and a V-shaped nozzle 520 .

[0035] Specifically, one end of the water outlet pipe 510 is connected to the second X-axis horizontal pipe 4 and the second Z-axis vertical pipe 8 through a tee pipe, and the other end of the water outlet pipe 510 is used to install the V-shaped nozzle 520. The length of the water outlet pipe 510 of the first spray gun 5 is set according to the second X-axis horizontal pipe 4, and the nozzle is placed as close as possible to the top of the trough of the second sedimentation tank outlet trough away from the trough body on both sides to improve the flushing efficiency. Similarly, the V-shaped nozzle 520 of the second spray gun 9 is also placed as close as possible to the trough wall of the second sedimentation tank outlet trough.

[0036] Furthermore, the axes of the first X-axis horizontal tube 3 and the second X-axis horizontal tube 4 are in the same plane.

[0037] Specifically, the first X-axis horizontal pipe 3 and the second X-axis horizontal pipe 4 can be a pipe that is first led upward from the outlet of the high-pressure submersible pump 2 placed in the secondary sedimentation tank, and then bent horizontally until the end is connected to two first spray guns 5. It should be noted that the height of the first X-axis horizontal pipe 3 is adjustable, depending on the distance between the first spray gun 5 and the top of the trough body on both sides of the secondary sedimentation tank outlet trough.

[0038] Furthermore, a plurality of connecting brackets 10 are provided between the first X-axis horizontal pipe 3 and the traveling frame above the secondary sedimentation tank.

[0039] Specifically, the connecting bracket 10 is used to fix the first X-axis horizontal pipe 3, and ensure that the first spray gun 5 and the second spray gun 9 move with the rotation of the traveling frame around the center of the second sedimentation tank. The moving direction of the first spray gun 5 and the second spray gun 9 is always the tangential direction of the rotation of the end of the traveling frame.

[0040] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
