Description

Technical Field

[0001] The present application relates to the field of sewage treatment, and in particular to a sludge cleaning device for sewage treatment. Background Art

[0002] Wastewater treatment is a procedure that is often required in the current industrial production field, especially for various industries such as textiles, papermaking, printing and dyeing, and chemicals. Due to the large amount of wastewater, if reliable sewage treatment is not carried out, it will cause extremely serious pollution to the environment. The main role of the tap water sedimentation tank in sewage treatment is to remove the precipitated sludge.

[0003] For example, the sludge cleaning device for the horizontal flow sedimentation tank of a water plant with application number CN202222704389.0 still has the following deficiencies in actual use:

[0004] When cleaning the sludge in the sedimentation tank, the above patent requires the use of a desludging bucket to transport the sludge multiple times, which makes the work efficiency very slow. At the same time, it is used in conjunction with a lead screw and a scraper. The height of the scraper is limited, and excessive sludge will overflow and reduce the cleaning effect. At the same time, the lead screw, scraper and other devices are easily corroded when immersed in sewage for a long time, which also aggravates water pollution. Summary of the Invention

[0005] In order to improve the problems of aggravated water pollution and low cleaning efficiency, the present application provides a sludge cleaning device for sewage treatment.

[0006] The sludge cleaning device for sewage treatment provided in this application adopts the following technical solution:

[0007] A sludge cleaning device for sewage treatment comprises a sedimentation tank and a traveling device on both sides of the sedimentation tank, wherein the traveling device comprises a traveling frame;

[0008] A connecting plate arranged at the lower end of the frame is fixedly provided in the middle of the upper end of the frame via a reduction motor, and winches for controlling the first and second collecting frames are fixedly provided on both sides of the upper end of the frame, and one end of the second collecting frame is movably plugged into the inner wall of the first collecting frame;

[0009] A partition is fixedly provided on one side of the interior of the collection frame 1, and a waterproof motor for driving the auger 1 to rotate is fixedly provided between the outer wall of the collection frame 2 and the partition. An auger 2 is rotatably provided on one end of the collection frame 2 facing the auger 1 and is movable and interlaced inside the central axis of the auger 1.

[0010] A sewage suction pipe fixedly connected to the bottom of the inner cavity of the collecting frame is provided between the second auger and the first auger, and the end of the sewage suction pipe is away from the transverse tangent of the second auger and the first auger.

[0011] By adopting the above technical solution, the setting of auger two and auger one can gather the sludge on both sides of the sedimentation tank towards each other, thereby facilitating cleaning. At the same time, the length of collection frame one and collection frame two can be changed to be suitable for sedimentation tanks of different widths.

[0012] Preferably, the output shaft of the reduction motor movably passes through the frame, and the upper end surface of the frame is in contact with a limit plate which is fixedly sleeved with the output shaft of the reduction motor.

[0013] By adopting the above technical solution, the rack can achieve the supporting effect of each structure. At the same time, the setting of the limit plate prevents the collection frame and other structures from pulling on the output shaft of the reduction motor, causing abnormal damage to the motor bearings. The limit plate plays a limiting role and effectively protects the reduction motor.

[0014] Preferably, limiting frames that fit with a surface of the collecting frame are fixedly provided on both sides of one end of the connecting plate away from the sewage suction pipe, and the limiting frames extend to the interior of the sedimentation tank.

[0015] By adopting the above technical solution, the limiting frame can guide the lifting and lowering of the collecting frame 1 and also promote the rotation of the collecting frame 1.

[0016] Preferably, an opening is provided at the upper end of the rack, which is located directly below the winch, and the steel ropes of the two winches pass through the opening and are fixed to the upper ends of the collecting frame 1 and the collecting frame 2 respectively.

[0017] By adopting the above technical solution, the setting of the winch can lower the collecting frame to the specified position. At the same time, the setting of the two steel ropes makes the collecting frame movable and easy to adjust, making it more flexible.

[0018] Preferably, a sewage discharge pipe 1 detachably fixed to the sewage suction pipe is fixed on one side of the rack surface, a sewage discharge pipe 2 is fixed on the rack surface at an angle opposite to the sewage discharge pipe 1, and the sewage suction pipe is rotated 180 degrees to be spliced and fixed to the sewage discharge pipe 2.

[0019] By adopting the above technical solution, the arrangement of the second sewage pipe and the first sewage pipe enables the suction pipe to be rotated to two positions to achieve sludge suction.

[0020] Preferably, the collecting frame 1 is provided with a symmetrical T-shaped groove on one side of the collecting frame 2, and the collecting frame 2 is provided with a T-shaped plate inserted into the T-shaped groove on one side of the collecting frame 1.

[0021] By adopting the above technical solution, the T-shaped groove plays a role of limiting the T-shaped plate and can change the length of the second collecting frame and the first collecting frame at the same time.

[0022] Preferably, a cross slot is provided in the middle of the central shaft of the first auger, and a cross rod movably inserted into the cross slot is fixed to the central shaft of the second auger.

[0023] By adopting the above technical solution, the cross rod slides in the cross slot so that the distance between the auger 2 and the auger can be adjusted while the auger 2 rotates.

[0024] Preferably, the collecting frame 1 is provided with a slot for inserting one end of the collecting frame 2 on the other side of the collecting frame 2, and the collecting frame 1 is fixed with an inclined plate at the lower end of the sewage suction pipe.

[0025] By adopting the above technical solution, the arrangement of the inclined plate can achieve the effect of cutting the sludge and at the same time transport the sludge to the inside of the collecting frame 1 and the collecting frame 2.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The winch can be used to transport auger two and auger one to the designated location. At the same time, the distance between collection frame one and collection frame two can be changed to adapt to sedimentation tanks of different widths, increasing cleaning efficiency and the practicality of the device. At the same time, the winch can remove auger two and auger one from the sedimentation tank when not in use to avoid prolonged immersion in sewage, which can easily corrode and aggravate water pollution. Secondly, the cleaning efficiency of the auger combined with the vacuum suction method of sludge makes the cleaning efficiency even higher;

[0028] 2. With the help of the reduction motor, the second and first auger rotates 180 degrees, which can realize the second or multiple cleaning of the sedimentation tank. It is very convenient, the working time is short, and the cleaning efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following is combined with Figure 1 - Figure 5 This application is described in further detail.

[0038] The embodiment of the present application discloses a sludge cleaning device for sewage treatment.

[0039] Reference Figure 1 A sludge cleaning device for sewage treatment includes a sedimentation tank 1. The sedimentation tank 1 is an existing structure with a ground at both ends, and a walking device 4 on both sides of the sedimentation tank 1. The walking device 4 is an existing structure and can use a gantry to achieve the purpose of walking. It is equipped with rollers, motors and other driving devices. It will not be described in detail for the existing device. The walking device 4 includes a running frame 2 for installing various structures.

[0040] The traveling device 4 can be used to drive the cleaning device to move inside the sedimentation tank 1, thereby cleaning the sludge inside the sedimentation tank 1.

[0041] Reference Figure 1 、 Figure 2 、 Figure 4 The mounting end of the reduction motor 6 is fixed to one end of the frame 2 by bolts, and the output shaft of the reduction motor 6 is movable through the serial port opened at the upper end of the frame 2, and the upper end surface of the frame 2 abuts against the limit plate 18. The contact surface between the upper end of the frame 2 and the lower end of the limit plate 18 is set to a smooth surface to reduce friction resistance and save energy. The perforation in the middle of the limit plate 18 is fixed to the surface of the output shaft of the reduction motor 6, and the connecting plate 19 is away from the end of the sewage suction pipe 11. Parallel limit frames 8 are fixed on both sides, and the surfaces of the two limit frames 8 are in contact with the surface of the collecting frame 9 to achieve sliding. The lower end of the limit frame 8 extends to the inside of the sedimentation tank 1. The length of the limit frame 8 can achieve that one end of the inclined plate 12 is in contact with the bottom of the sedimentation tank 1 without being separated from the collecting frame 9. The limit frame 8 is preferably made of stainless steel, which is not easy to rust and avoids pollution of the water body.

[0042] Under the action of gravity of the connecting plate 19 and the two limiting frames 8, the limiting plate 18 is tightly abutted against the row frame 2. At this time, the reduction motor 6 is powered on, and the output shaft of the reduction motor 6 rotates to drive the limiting plate 18, the connecting plate 19 and the limiting frame 8 to rotate. It should be noted that when the collecting frame 1 9 and the collecting frame 2 20 rotate, the collecting frame 1 9 and the collecting frame 2 20 rotate in the air or at the top. At the same time, when the collecting frame 1 9 and the collecting frame 2 20 rotate slowly, the two winches 3 need to slowly release the steel rope to replenish The radius of rotation changes. When the collection frame 1 9 and the collection frame 2 20 rotate 180 degrees, the steel ropes of the two hoists 3 are in a crossed state. In this state, it is necessary to note that when the collection frame 1 9 and the collection frame 2 20 rotate to their original positions, the reduction motor 6 can only rotate in the opposite direction to restore the steel ropes of the two hoists 3 to a parallel state. Otherwise, the reduction motor 6 continues to rotate after the rotation, causing the two steel ropes to tangle and knot, which will increase the wear of the steel ropes and affect the lifting and lowering of the collection frame 1 9 and the collection frame 2 20. The two limit frames 8 can push the collection frame 1 9 and the collection frame 2 20 to move and play a supporting role.

[0043] Because the steel rope of the winch 3 is wound, in order to avoid the distance difference caused by the steel rope when it is wound, a fixed pulley needs to be set on the opening 5. Specifically, a linear drive mechanism is fixed on one side of the opening 5, and the mounting end of the fixed pulley is fixed to the moving end of the linear drive mechanism, so that one end of the steel rope can maintain a vertical state as the other end moves (the fixed pulley is not shown in the figure). At the same time, adjusting the position of the fixed pulley can directly adjust the distance between the auger 14 and the auger 2 15, and then adjust the total length of the collection frame 1 9 and the collection frame 2 20, so that it can be adjusted according to the sedimentation tank 1 of different widths, thereby increasing the practicality and applicability of the device.

[0044] Reference Figure 1 、 Figure 2 、 Figure 4, both sides of the upper end of the row frame 2 are fixed with winches 3, and the two winches 3 respectively control the lifting of the collection frame 1 9 and the collection frame 2 20. The collection frame 1 9 is located on one side of the collection frame 20 and has two T-shaped slots 21. The two T-shaped slots 21 are symmetrical to each other. The collection frame 2 20 is located on one side of the collection frame 1 9 and is fixed with a T-shaped plate 24. The T-shaped plate 24 is inserted into the T-shaped slot 21 and realizes lateral movement. At the same time, the contact surface of the T-shaped plate 24 and the T-shaped slot 21 is provided with lubricating oil. The collection frame 1 9 is located on the other side of the collection frame 20 and has an L-shaped slot 23. One end of the collection frame 20 is movably inserted into the slot 23, and one end of the collection frame 20 is set to be L-shaped. It should be noted that Yes, the thickness of the other end of the collecting frame 20 is the same as that of the collecting frame 1 9. The collecting frame 1 9 is fixed with an inclined plate 12 on the side of the lower end of the suction pipe 11. The inclined plate 12 is preferably made of flexible rubber material. The flexible setting can be cut and spliced for installation, and thus has the same flexibility as the width of the sedimentation tank 1. Openings 5 are provided on both sides of the upper end of the row frame 2. The openings 5 are located directly below the winch 3 and the length of the opening 5 is the same as or greater than the length of the winding drum of the winch 3, which can effectively avoid contact between the steel rope and the row frame 2. The steel ropes of the two winches 3 pass through the openings 5 respectively, and the two steel ropes are fixed to the upper end of the collecting frame 1 9 and the upper end of the collecting frame 20 respectively.

[0045] When the distance between the two steel ropes is fixed, the user can push the collection frame 2 20 to make the collection frame 2 20 slide inside the collection frame 1 9 and make the T-shaped plate 24 slide in the T-shaped groove 21, thereby adjusting the length between the collection frame 2 20 and the collection frame 1 9. Secondly, the length of the collection frame 2 20 between the collection frame 1 9 can also be changed by driving the fixed pulley to move through the set linear drive mechanism (note that when the fixed pulley is set to one, the fixed pulley can only adjust the position of the steel rope in one direction. If there are two fixed pulleys that clamp the steel rope in the middle, the position of the steel rope can be adjusted in two directions. The specific user can set it according to the actual situation: the relevant structure is not shown in the above description figure).

[0046] Reference Figure 3, one side surface of the interior of the collecting frame 9 is fixed to the three surfaces of the partition 13, and a gap is provided between one end of the partition 13 and an end surface of the collecting frame 9. In order to protect the waterproof motor 16, it needs to be closed by screws and a cover to prevent sludge from entering. A waterproof motor 16 is fixed between the outer wall of the collecting frame 20 and the partition 13. The output shaft of the waterproof motor 16 is movable through the partition 13 and is fixed to the central axis of the driving auger 14 to drive the auger 14 to rotate. A cross slot 22 is provided in the middle of the end of the central axis of the auger 14 away from the waterproof motor 16, and a cross rod 17 is fixed to the central axis of the auger 2 15, which is movably inserted into the cross slot 22. At the same time, the spiral direction of the auger 14 is opposite to the spiral direction of the auger 2 15, thereby transporting the soil on both sides to between the auger 14 and the auger 2 15 and located at the front end of the sewage suction pipe 11.

[0047] The waterproof motor 16 is powered on to work, and the output shaft of the waterproof motor 16 drives the auger 14 to rotate and transports the sludge at the bottom of the sedimentation tank 1 in one direction. At the same time, the cross slot 22 drives the cross rod 17 to rotate and then drives the auger 2 15 to rotate to transport the sludge at the other end of the bottom of the sedimentation tank 1. The sludge in two directions is transported to the front end of the sewage suction pipe 11.

[0048] At the same time, when the length between the collecting frame 20 and the collecting frame 1 9 changes, the cross rod 17 is moved in the cross groove 22 to adjust the distance between the auger 2 15 and the auger 1 14. It should be noted that even if the auger 2 15 and the auger 1 14 are in contact with each other, the surfaces of the auger 2 15 and the auger 1 14 will not contact the end of the sewage suction pipe 11 and there will still be space for storing sludge.

[0049] Reference Figure 3-Figure 5 A sewage suction pipe 11 is provided between the auger 2 15 and the auger 1 14, and one side of the lower surface of the sewage suction pipe 11 is fixedly connected to the bottom of the inner cavity of the collecting frame 1 9. The contact area between the sewage suction pipe 11 and the bottom of the inner cavity of the collecting frame 1 9 is not large and is suspended on one side of the collecting frame 20 so as not to affect the movement of the collecting frame 2 20. The end of the sewage suction pipe 11 is away from the transverse tangent of the auger 2 15 and the auger 14 so as to avoid interference between the two. A sewage discharge pipe 7 is fixedly provided on one side of the surface of the rack 2, and one end of the sewage discharge pipe 7 can be fixed to the sewage suction pipe 11 by bolts or a quick-release structure. The quick-release structure is a prior art and will not be described in detail. A sewage discharge pipe 2 10 is fixed to the other side surface of the rack 2, and the sewage discharge pipe 2 10 is diagonally arranged to the sewage discharge pipe 7. The sewage suction pipe 11 is rotated 180 degrees to be spliced and fixed to the sewage discharge pipe 2 10, and the sewage suction pipe 11 and the sewage discharge pipe 2 10 can be fixed by bolts or a quick-release structure.

[0050] First, connect the sewage pipe 2 10 or the sewage pipe 1 7 to the external vacuum suction device. Then, the vacuum suction device generates negative pressure in the sewage pipe 2 10 or the sewage pipe 1 7, and then generates negative pressure in the sewage suction pipe 11 to suck the sludge at the front end of the sewage suction pipe 11 to achieve the cleaning effect. When the device cleans from one end of the sedimentation tank 1 to the other end, the collection frame 2 20 and the collection frame 1 9 can be rotated 180 degrees for further cleaning. Before rotation, the bolts or quick-release structure between the sewage suction pipe 11 and the sewage pipe 1 7 need to be removed and unlocked to make the sewage suction pipe 11 and the sewage pipe 7 active. After the collection frame 2 20 and the collection frame 1 9 are rotated 180 degrees, the sewage suction pipe 11 corresponds to the sewage pipe 2 10. Then, the user fixes it with bolts or quick-release structures to further clean the sludge at the bottom of the sedimentation tank 1.

[0051] The vacuum suction device is preferably a dredge suction pump.

[0052] Among them, the linear drive mechanism, waterproof motor 16, reduction motor 6 and winch 3 are existing technologies, and their structural principles will not be described in detail. At the same time, this device also includes power supply, controller, wires and remote control devices, which are not the main technologies and will not be described in detail.

[0053] The implementation principle of the sludge cleaning device for sewage treatment in the embodiment of the present application is as follows:

[0054] When the sedimentation tank 1 needs to be cleaned, the user controls the remote control to release the steel ropes of the two winches 3, thereby moving the collecting frame 9 away from the connecting plate 19 and making the bottom of the collecting frame 9 and the inclined plate 12 contact with the bottom of the sedimentation tank 1. Then, the walking device 4 is powered on and moves, and the output shaft of the reduction motor 6 is used to achieve support and then push the collecting frame 9 to move through the connecting plate 19 and the limit frame 8. At the same time, the waterproof motor 16 drives the auger 14 and the auger 2 15 to rotate to gather the sludge, and then generates negative pressure through the vacuum suction device to discharge the sludge through the suction pipe 11 and the discharge pipe 7, thereby achieving a quick cleaning effect.

[0055] When secondary cleaning is required, the reduction motor 6 drives the connecting plate 19 and the limiting frame 8 to rotate, and the limiting frame 8 pushes the collecting frame 9 to rotate, so that the collecting frame 9 rotates 180 degrees, and then repeats the above cleaning operation.

[0056] In summary, when the device is not in use, the auger 14 and the auger 2 15 are at the upper end of the sedimentation tank 1 and are not in contact with the water inside. Therefore, it can effectively avoid being easily corroded by being immersed in sewage for a long time and at the same time avoid aggravating water pollution. Secondly, the cleaning efficiency of the auger combined with the vacuum suction method of sludge makes the cleaning efficiency higher.

[0057] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
