Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sludge discharging device for sewage treatment. Background Technique

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it. Sewage treatment is widely applied in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and is also increasingly entering the daily life of ordinary people.

[0003] Sewage treatment has received more and more attention. Existing sewage treatment methods include physical sedimentation method, chemical sedimentation method, biodegradation method, etc. However, no matter which method is used for sewage treatment, a large amount of sludge will accumulate at the bottom of the sewage treatment device after a period of time. In order to ensure the normal and effective progress of sewage treatment, it is often necessary to clean and discharge the sludge inside the sewage treatment device during use. However, most of the current methods for cleaning the sludge inside the sewage treatment device are that workers use cleaning tools to flush water into the sewage treatment device, separate the sludge from the inner wall surface of the sewage treatment device, and then use cleaning tools to remove the sludge inside the sewage treatment device. The large amount of sludge accumulated inside the device is not only inconvenient to remove, but also increases the labor intensity of workers. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] As Figures 1-4 shown: A sludge discharging device for sewage treatment includes a base 1 and a sewage treatment tank 2 arranged above the base 1, and is characterized in that it further includes:

[0017] Support plates 3 bolted to the left and right sides of the base 1, a motor 4 is fixed to the lower part of the outer side of the support plates 3, the sewage treatment tank 2 is rotatably connected between the two support plates 3, and a flipping structure 5 for inverting the sewage treatment tank 2 is arranged inside the support plates 3;

[0018] Above the base 1, there is also a receiving platform 6. A sludge tank 7 is provided at the top of the receiving platform 6. A lifting structure 8 is provided between the base 1 and the receiving platform 6. Four mounting boxes 9 are arranged in an array on the top of the receiving platform 6. A water pipe 10 is communicated with the outside of the mounting box 9. A spray head 11 communicated with the water pipe 10 is provided on the top of the mounting box 9.

[0019] The flipping structure 5 includes a first timing pulley 51 arranged below the inner wall of the support plate 3, a second timing pulley 52 rotatably connected above the inner wall of the support plate 3, and a timing belt 53; the timing belt 53 is wound around the first timing pulley 51 and the second timing pulley 52; a rotating shaft 54 is coaxially provided on the second timing pulley 52, and the output shaft of the motor 4 is coaxially connected with the first timing pulley 51; the rotating shaft penetrates out of the support plate 3 and is fixedly connected with the sewage treatment tank 2.

[0020] When the motor 4 is turned on, the output shaft of the motor 4 drives the first timing pulley 51 to rotate, so that the timing belt 53 drives the second timing pulley 52 above to rotate, and the rotating shaft 54 drives the sewage treatment tank 2 to flip, so as to perform sludge discharge operation on the inside of the sewage treatment tank 2.

[0021] The lifting structure 8 includes a threaded rod 81, a moving platform 82 and a connecting rod 83; the threaded rod 81 is rotatably connected between the two support plates 3, and the output shaft of the motor 4 is fixedly connected to the end of the threaded rod 81; two moving platforms 82 are provided and the two moving platforms 82 are respectively arranged at both ends of the threaded rod 81, and the moving platform 82 is in threaded cooperation with the threaded rod 81; one end of the connecting rod 83 is hinged to the side of the moving platform 82, and the other end of the connecting rod 83 is hinged to the bottom of the moving platform 82.

[0022] The threaded rod 81 here is a positive and negative threaded rod with opposite threaded directions at both ends.

[0023] When the threaded rod 81 rotates, the moving platforms 82 on the left and right sides of the surface of the threaded rod 81 will move towards or in the opposite direction, so that the connecting rods 83 on both sides move, and the connecting rods 83 push the receiving platform 6 above to move, and the height of the receiving platform 6 is adjusted.

[0024] A limiting groove 12 is provided on the surface of the top of the base 1. A limiting block 13 slidably connected to the inner wall of the limiting groove 12 is fixed to the bottom of the moving platform 82. Both the left and right sides of the receiving platform 6 are in contact with the surface of the support plate 3, and the receiving platform 6 is slidably connected to the surface of the support plate 3.

[0025] When the threaded rod 81 rotates, the lower limit block 13 limits the movement of the moving platform 82, so that the moving platform 82 can only move in the left - right direction, improving the stability of the receiving platform 6 during its up - and - down movement. Moreover, the support plate 3 can also guide the receiving platform 6, further improving the stability of the receiving platform 6 during its up - and - down movement.

[0026] The water - passing pipe 10 is a telescopic hose. The top surface of the installation box 9 inclines inward, and the drainage direction of the nozzle 11 faces the bottom of the sewage treatment tank 2.

[0027] After the sewage treatment tank 2 is overturned, the receiving platform 6 moves upward. After the staff passes water into the interior of the water - passing pipe 10, the water flows into the installation box 9 and is discharged from the nozzle 11. The nozzle 11 sprays the water into the interior of the sewage treatment tank 2, thereby flushing the sludge attached to the inner wall surface of the sewage treatment tank 2, so that the sludge and sewage fall into the lower sludge tank 7.

[0028] Working principle: When the staff needs to clean the sludge in the sewage treatment tank 2, the staff first turns on the motors 4 on both sides, so that the output shafts of the motors 4 drive the first timing belt pulleys 51 to rotate, and finally drive the upper sewage treatment tank 2 to overturn; at this time, the opening at the upper part of the sewage treatment tank 2 faces downward. At the same time, the lower threaded rod 81 also rotates, causing the receiving platform 6 to rise, and the nozzle 11 gets as close as possible to the opening of the sewage treatment tank 2. Then the staff passes water into the interior of the water - passing pipe 10, and then the nozzle 11 sprays the water; the water flushes on the inner wall surfaces of various parts of the sewage treatment tank 2, so that the sludge on the inner wall surface of the sewage treatment tank 2 will fall, and the sludge and sewage fall into the lower sludge tank 7. After a period of flushing, the staff can control the motor 4 again to turn the sewage treatment tank 2 back to its original position, and the receiving platform 6 also descends to its original position; then the staff can treat the sewage and sludge in the sludge tank 7 to complete the sludge discharge treatment of the sewage treatment tank 2.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
