Description

Technical Field

[0001] The utility model relates to the field of sewage treatment equipment, and particularly relates to an inclined tube cleaning device. Background Art

[0002] The situation of water pollution is intensifying continuously, and the topic of water pollution is constantly mentioned. The environmental protection awareness of the public has gradually awakened, and the concern about water pollution has reached an unprecedented level. In order to make the sewage meet the water quality requirements for discharging into a certain water body or being reused, it is necessary to purify it, and this process is called sewage treatment. At present, there is a steel plant wastewater treatment center undertaking the wastewater treatment tasks such as industrial wastewater, domestic sewage, rainwater, rural irrigation external drainage and surface drainage in the plant area. The wastewater treatment center is equipped with advanced environmental protection equipment such as coarse and fine grids, regulating tanks, D-type filters, high-efficiency reaction sedimentation tanks, plate and frame pressure filters, etc., and adopts the technologies of regulation and high-efficiency coagulation sedimentation to meet the industrial wastewater pollutant discharge standards. Among them, the high-efficiency reaction sedimentation tank includes an inclined tube sedimentation tank, which refers to a sedimentation tank provided with inclined tubes in the sedimentation area. In the sedimentation area of the inclined tube sedimentation tank, a series of shallow sedimentation layers are divided by inclined parallel tubes or parallel pipelines (sometimes honeycomb inclined tube fillers can be used, mainly for sedimentation and sand removal). The treated and settled sludge moves and separates from each other in each shallow sedimentation layer.

[0003] Although the inclined tubes are beneficial to improving the sedimentation efficiency of the sedimentation tank, there is still an important problem in the operation of the inclined tube sedimentation process: sludge is easily attached and accumulated on the inner wall and the top of the inclined tubes, resulting in poor effluent water quality and the need for regular cleaning. Usually, after the effluent water quality deteriorates, the water level of the tank is lowered by stopping the tank and high-pressure water flushing is carried out manually. However, due to the long cleaning interval, the sludge will deposit and solidify on the inclined tubes, and it is often difficult to completely remove the sludge. In severe cases, the inclined tubes even need to be replaced. The cleaning frequency is basically once a month for each sedimentation tank, 4 people are required each time, and each cleaning needs to be continuously operated for 5 hours. Such a cleaning method has low operation efficiency. Since it is manual flushing and the sedimentation tank is large, the inclined tubes in the middle position of the sedimentation tank are far from the operators, resulting in poor cleaning effect and slow speed, and the labor intensity is large. The sedimentation tank is outdoors, and manual flushing is also affected by the weather. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an inclined tube cleaning device to replace manual cleaning, which has a larger flushing range and a larger flushing pressure, can improve the quality and speed of cleaning the inclined tubes, save time, improve work efficiency, and can also increase the cleaning frequency of the inclined tubes to prevent more sludge from depositing and solidifying on the inclined tubes and being difficult to remove.

Detailed implementation manners

[0026] In this text, unless otherwise specified, the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "top", "bottom", etc. are used to indicate the orientation or positional relationship based on the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation and operation, so it should not be construed as a limitation to the present utility model.

[0027] The following will describe the specific implementation manners of the present utility model in more detail with reference to the schematic diagrams. According to the following description, the advantages and features of the present utility model will be clearer. It should be noted that the drawings are all in a very simplified form and use non-precise scales, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present utility model.

[0028] Figure 1 is a top view of a inclined tube cleaning device according to an embodiment of the present utility model, Figure 2 is an axonometric view of a inclined tube cleaning device according to an embodiment of the present utility model. Please refer to Figure 1 and Figure 2 According to an embodiment of the present utility model, a inclined tube cleaning device is provided, which includes an inclined tube sedimentation tank, a traveling component 2 and a cleaning component.

[0029] The inclined tube sedimentation tank includes a tank body and an inclined tube assembly 1 arranged in the tank body. The inclined tube assembly 1 includes a plurality of parallel inclined tubes 11. It can be understood that during the operation of the inclined tube sedimentation tank, the sludge on the inner wall of the inclined tubes will increase, affecting the water quality. Therefore, it is necessary to regularly wash the inclined tubes 11.

[0030] The traveling component 2 includes a track 22 and a traveling vehicle 21. The traveling vehicle 21 can move on the track 22, that is, the moving direction of the traveling vehicle 21 is parallel to the extending direction of the track 22. Further, the track 22 includes a first track 221 and a second track 222 that are parallel to each other. The first track 221 and the second track 222 are located on both sides of the tank body. The two ends of the traveling vehicle 21 are respectively located on the first track 221 and the second track 222 and can move along the first track 221 and the second track 222, and the traveling vehicle 21 is located above the tank body. For example, if the inner cavity of the tank body is a cuboid, the first track 221 and the second track 222 are parallel to two opposite sides of the tank body. It can be understood that the lengths of the first track 221 and the second track 222 are both longer than the length of the inclined tube assembly 1 in the moving direction of the traveling vehicle 21, so that the moving range of the traveling vehicle 21 can cover the entire inclined tube assembly 1.

[0031] The inclined tube cleaning device includes a driving assembly 3 for driving the traveling crane 21 to move. The driving assembly 3 includes a motor. Further, the driving assembly 3 includes a speed reducer for reducing the speed of the motor. Preferably, the motor can be a variable frequency motor, and the moving speed of the traveling crane 21 can be changed by adjusting the frequency of the variable frequency motor to achieve stepless speed regulation. Exemplarily, the driving assembly 3 can be installed on the traveling crane 21.

[0032] The traveling crane assembly 2 includes two travel switches 23, which are respectively located at two end points of the moving range of the traveling crane 21 on the track 22, enabling the traveling crane 21 to reciprocate within the moving range. It can be understood that the travel switch 23 is a type of position switch, a commonly used small-current master electrical appliance. It uses the collision of the moving parts of the production machinery to actuate its contacts to achieve the on or off control circuit and reach a specific control purpose. Usually, such switches are used to limit the position or stroke of the mechanical movement, so that the moving machinery can automatically stop, reverse, change speed, or move back and forth automatically at a certain position or stroke. For example, in this embodiment, when the traveling crane 21 reaches the end point of the moving range, it just triggers the travel switch 23, thereby changing the moving direction and moving in the reverse direction. In this way, the traveling crane 21 can move back and forth within the moving range, and the inclined tube 11 can be washed more cleanly and thoroughly.

[0033] For safety, the traveling crane assembly 2 further includes two stoppers 24, which are respectively located on both sides of the moving range and outside the moving range, that is, the two travel switches 23 are located between the two stoppers 24. If the travel switch 23 fails, the stopper 24 can play a role in blocking the continuous movement of the traveling crane 21 and driving it out of the track 22, playing a safety protection role.

[0034] The cleaning assembly includes a water delivery pipe 41 and a plurality of nozzles 42 communicated with the water delivery pipe 41. The water delivery pipe 41 is connected to the traveling crane 21. The nozzles 42 are located above the pool body. The nozzles 42 are used to move along with the traveling crane 21 to wash the inclined tube assembly 1. The nozzle of the nozzle 42 is a flat mouth, and the long axis direction of the flat mouth is perpendicular to the moving direction of the traveling crane 21. The water spraying direction of the nozzle 42 is consistent with the inclination angle of the inclined tube. For reference, Figure 3 . Specifically, the water delivery pipe 41 includes a first pipe 411 and a second pipe 412 communicated with each other. The second pipe 412 is installed on the traveling crane 21. A plurality of nozzles 42 are evenly distributed on the second pipe 412. The first pipe 411 is a flexible pipe. The second pipe 412 can be a straight pipe, for example, and the second pipe 412 is perpendicular to the moving direction of the traveling crane 21. The nozzle of the nozzle 42 is a flat mouth, and the sprayed water is in a fan shape. For reference, Figure 4, the water sprayed between adjacent nozzles 42 can overlap. The long axis direction of the flat nozzle is perpendicular to the moving direction of the traveling vehicle 21. The water sprayed by all nozzles 42 is basically in the same plane, with a large flushing range, and there will be no dead corners of the inclined pipes missed and not flushed properly. Moreover, the spraying direction of the nozzles 42 is consistent with the inclination angle of the inclined pipes, so the sprayed water can reach the bottom of the inclined pipes all the time, flushing the entire inclined pipes in place. For example, reference can be made to Figure 3 and Figure 4 , branch pipes 43 corresponding to the nozzles 42 one by one can be provided on the second pipeline 412, and the nozzles 42 can be connected to the branch pipes 43 by threads.

[0035] Furthermore, the inclined pipe cleaning device includes a support assembly for supporting the first pipeline 411. The support assembly includes a guide member 51 and a plurality of hanging rings 52. The plurality of hanging rings 52 are sleeved on the guide member 51 and can slide along the guide member 51. The plurality of hanging rings 52 are connected to the first pipeline 411, and the plurality of hanging rings 52 are spaced apart on the first pipeline 411. It can be understood that the first pipeline 411 can move on the guide member 51 through the hanging rings 52, similar to the movement of a curtain. The guide member 51 is parallel to the moving direction of the traveling vehicle 21, and the length of the first pipeline 411 is greater than the moving range of the traveling vehicle 21, so that the traveling vehicle 21 can move freely within the moving range without being restricted by the too short first pipeline 411. Exemplarily, the guide member 51 can be a steel wire rope or a rod, and a bracket 53 can be provided to support and fix the guide member 51.

[0036] Generally, the inclined pipe cleaning device further includes a water inlet assembly. The water inlet assembly includes a water inlet pipe 61, a water pump 62 and a regulating valve 63 with adjustable opening. The water inlet pipe 61 is communicated with the water conveying pipeline 41. The water outlet of the water pump 62 is connected to the water inlet pipe 61. The water inlet of the water pump 62 is used to connect to a water tank 7. The water pump 62 is used to pump the liquid in the water tank 7 to the water inlet pipe 61, and the regulating valve 63 is arranged on the water inlet pipe 61. Specifically, the water inlet pipe 61 is communicated with the first pipeline 411 to convey the liquid in the water tank 7 to the first pipeline 411 for flushing the inclined pipes 11. The water supply pressure of the water pump 62 can be adjusted to about 0.8 - 1 MPa, for example. A pressure gauge 64 is provided on the water inlet pipe 61 to detect the pressure of the liquid, and the pressure of the liquid can be controlled by coordinating with the opening adjustment of the regulating valve 63. Further, the water inlet pipe 61 can be communicated with the first pipeline 411 through a quick connector, which is convenient for quick disassembly. Therefore, if there are multiple inclined pipe sedimentation tanks and only one inclined pipe sedimentation tank is flushed at a time, only one water pump 62 needs to be equipped, saving equipment costs.

[0037] The inclined pipe cleaning device can also include a control module. The control module can be located in the central control room, for example. The control module is electrically connected to the driving assembly 3 and the regulating valve 63, and can remotely control the cleaning operation of the inclined pipes 11 in the central control room.

[0038] Based on the above inclined tube cleaning device, this embodiment further provides an inclined tube cleaning method, and the cleaning method includes: starting the traveling crane, moving the traveling crane on the rail, and the spray head follows the traveling crane to move, so that the cleaning water is sprayed out from the spray head and sprayed onto the inclined tube to wash the inclined tube.

[0039] For example, start the traveling crane assembly to move the traveling crane 21 on the rail 22, and the spray head follows the traveling crane 21 to move. Exemplarily, start the driving assembly 3 to drive the traveling crane 21 to move on the rail 22. The moving speed of the traveling crane 21 can be changed by adjusting the frequency of the frequency conversion motor, and the moving speed can be 20 m / min - 30 m / min, such as 25 m / min.

[0040] Exemplarily, the cleaning method further includes: introducing the cleaning water into the water delivery pipeline, so that the cleaning water is sprayed out from the spray head 42 and sprayed onto the inclined tube 11, and the spraying direction of the spray head 42 is consistent with the inclination angle of the inclined tube 11.

[0041] Specifically, start the water pump 62 to pump the cleaning water in the water tank 7 into the water delivery pipeline. It can be understood that the flow rate and pressure of the cleaning water can be adjusted by changing the opening degree of the regulating valve 63. Exemplarily, according to the on-site needs, the flow rate of the cleaning water can be controlled at 15 m 3 / h - 20 m 3 / h. Starting the water pump 62 can be before starting the traveling crane assembly, or after starting the traveling crane assembly, or at the same time as starting the traveling crane assembly.

[0042] When the traveling crane 21 touches the travel switch 23, the traveling crane 21 changes the moving direction and moves in the reverse direction, so that the traveling crane 21 automatically makes a round-trip movement on the rail 22.

[0043] With the above configuration, the spray head 42 is driven to move by the traveling crane assembly 2, so as to wash the inclined tube assembly 1 while moving. The nozzle is set to be flat-mouthed, which not only increases the flushing water pressure but also expands the flushing range; the long axis direction of the flat mouth is perpendicular to the moving direction of the traveling crane 21, further expanding the flushing range; the spraying direction of the spray head 42 is consistent with the inclination angle of the inclined tube, so that the entire inclined tube can be washed. In summary, the utility model has a larger flushing range and a larger flushing pressure, and even the inclined tube in the middle of the pool can be washed, improving the quality and speed of cleaning the inclined tube, saving time. In the prior art, it takes 5 hours to clean manually once, while the utility model only takes one hour to clean once, improving the work efficiency, replacing manual cleaning in the prior art, reducing the labor intensity of the operators, and using this device to clean the inclined tube is not affected by the weather, and the cleaning work can be carried out at any time, and the frequency of cleaning the inclined tube can also be increased to prevent more sludge from depositing and solidifying on the inclined tube and being difficult to remove.
