Description

Technical Field

[0001] The invention belongs to the technical field related to soil infiltration treatment in sewage treatment, and in particular relates to a soil ecological treatment experimental device with adjustable operating parameters. Background Art

[0002] In the current field of soil infiltration treatment experiments, in order to improve the accuracy of the experiment, the method of spraying sewage into the soil ecological infiltration module in a dry-wet alternating manner is widely used. This method helps the microorganisms in the soil to fully decompose organic matter. For example, in a soil ecological treatment experimental device with adjustable operating parameters involved in a published patent (application number CN202221007936.3), dry-wet alternating treatment is achieved by controlling the rotation of the soil ecological infiltration module.

[0003] However, when the experimental device is running, when the soil ecological infiltration module rotates, a window period of sewage spraying will inevitably occur. During this period, the submersible sewage pump continues to run and transport sewage, which directly leads to ineffective loss of electric energy. In addition, in the later stage of the experiment, the way to obtain experimental infiltration data is usually to rely on manual measurement of the amount of clean water recovered from the clean water tank. This operation process is not only cumbersome, but also unable to monitor the infiltration effect in real time, which greatly affects the accuracy and timeliness of the experimental data and is difficult to meet the actual needs of the experiment.

[0004] To this end, we proposed a soil ecological treatment experimental device with adjustable operating parameters to solve the above problems. Summary of the invention

[0020] A driving mechanism 7 that cooperates with the rotating tube 4 is provided in the annular driving chamber 2.

The worm wheel 73 is fixedly sleeved on the rotating tube 4, and the worm wheel 73 is meshed with the worm 72. Through the transmission cooperation of the worm 72 and the worm wheel 73, the stepping motor 71 can drive the rotating tube 4 to rotate.

[0021] The support frame 8 is fixedly arranged on the base 1, and the sewage pump 9 is fixedly arranged on one side of the support frame 8. A telescopic tube 10 is fixedly arranged on the support frame 8, and a solenoid valve 11 is installed at the end of the telescopic tube 10. The telescopic port of the telescopic tube 10 is fixedly connected to a shower head 12, and the fixed port of the telescopic tube 10 is connected to the sewage pump 9 through an infusion tube 13. Two micro electric push rods 23 are fixedly arranged at the fixed end of the telescopic tube 10, and the output ends of the two micro electric push rods 23 are fixedly connected to the shower head 12. Through the arranged micro electric push rods 23, the spraying distance between the shower head 12 and the soil ecological infiltration module 6 can be adjusted as needed, and it is convenient to control the shower head 12 to give way to the soil ecological infiltration module 6 in the later stage, so that the disassembly of the soil ecological infiltration module 6 is not blocked.

[0022] The shower head 12 is located above each soil ecological infiltration module 6, an arc-shaped photoresistor sheet 14 is fixedly provided on the inner wall of one side of the annular driving cavity 2, a plurality of trigger lamps 15 matching the arc-shaped photoresistor sheet 14 are fixedly provided on the rotating tube 4, and each trigger lamp 15 corresponds to each soil ecological infiltration module 6 one by one, a trigger mechanism 16 is provided on the base 1, and the trigger mechanism 16 is electrically connected to the arc-shaped photoresistor sheet 14, and the trigger mechanism 16 is electrically connected to the sewage pump 9 and the solenoid valve 11.

[0023] The trigger mechanism 16 includes a trigger chamber 161, an electromagnetic block 162, a sliding pressing block 163, a permanent magnet block 164 and a press switch 165. The trigger chamber 161 is opened on the base 1, and the electromagnetic block 162 is fixedly arranged in the trigger chamber 161.

Through the set electromagnetic block 162, the corresponding magnetic change can be generated based on the resistance change of the arc-shaped photoresistor sheet 14. In conjunction with the permanent magnet block 164, the push switch 165 can be automatically controlled to be opened and closed based on the rotation position of the soil ecological infiltration module 6.

[0024] The liquid guiding cavity 3 is connected to the clean water tank 17 through a drainage pipe 27 , and a permeation data feedback mechanism 18 is arranged on the clean water tank 17 . A one-way valve 26 is installed on the drainage pipe 27 . The setting of the one-way valve 26 can prevent the clean water in the clean water tank 17 from flowing back.

[0025] The penetration data feedback mechanism 18 includes a piston float 181, a scale rod 182 and a pointer 183. The piston float 181 is slidably set in the clean water tank 17, and the scale rod 182 is fixedly set on the piston float 181. The upper end of the scale rod 182 penetrates the clean water tank 17. The pointer 183 is fixedly set on the upper side wall of the clean water tank 17, and the pointer 183 is arranged opposite to the scale rod 182. Through the set piston float 181, it can float to a corresponding height based on the amount of clean water entering the clean water tank 17, and then it will drive the scale rod 182 to automatically move up to a corresponding height. The data indicated by the pointer 183 can automatically reflect the current clean water volume data.

[0026] A protective cover 20 is fixedly provided on the upper side wall of the clear water tank 17, and a scale rod 182 passes through the protective cover 20. A CCD camera 21 is fixedly provided in the protective cover 20, and a fill light 22 is fixedly provided in the protective cover 20. The CCD camera 21 can form image data indicating the data of the pointer 183 and feed it back to the laboratory computer so that the staff can directly obtain the experimental data and avoid the tedious subsequent measurement. The fill light 22 can provide fill light for the CCD camera 21, and the protective cover 20 can protect the CCD camera 21.

[0027] The operating principle of the present invention is now described as follows: When using this device, each soil ecological infiltration module 6 is threadedly connected to the corresponding threaded port 24, and then the shower head 12 is controlled to move downward by the micro electric push rod 23. The spraying distance between the shower head 12 and the soil ecological infiltration module 6 can be adjusted according to the height of the soil ecological infiltration module 6 to ensure the spraying effect.

[0028] Next, the sewage pump 9 and the stepper motor 71 are started. The sewage pump 9 will transport the sewage used for the experiment in the sewage pool to the shower head 12 through the infusion tube 13. The shower head 12 will spray the sewage into the corresponding soil ecological infiltration module 6. The delivery power of the sewage pump 9 can be adjusted as needed to control the water spraying force of the shower head 12. The stepper motor 71 will control the rotation of the worm 72. Under the transmission cooperation of the worm gear 73, the rotating tube 4 will drive the various soil ecological infiltration modules 6 on the liquid guide seat 5 to rotate. When the initial soil ecological infiltration module 6 rotates away from the spraying range of the shower head 12, the initial soil ecological infiltration module 6 will rotate to the soil ecological infiltration module 6. The light irradiated by the corresponding triggering lamp 15 will move away from the arc-shaped photoresistor sheet 14, so that the resistance value of the arc-shaped photoresistor sheet 14 increases, and then the current passed through the electromagnetic block 162 decreases, and the repulsive force of the electromagnetic block 162 on the permanent magnet block 164 decreases, so that the sliding pressing block 163 moves upward under the pull of the reset spring 19, so that the pressing switch 165 automatically resets to the disconnected state, and then the sewage pump 9 is automatically shut down, and the electromagnetic valve 11 is automatically closed, so that the sewage in the telescopic tube 10 no longer enters the shower head 12, so that the shower head 12 stops spraying sewage and waits for the arrival of the next soil ecological infiltration module 6.

[0029] When the next soil ecological infiltration module 6 is in the spraying position of the shower 12, the light irradiated by the corresponding trigger light 15 will act on the arc-shaped photoresistor sheet 14, so that the resistance value of the arc-shaped photoresistor sheet 14 is automatically reduced, thereby re-enhancing the magnetism of the electromagnetic block 162. Similarly, at this time, the press switch 165 will be pressed and closed by the sliding press block 163 again, thereby restarting the sewage pump 9 and the electromagnetic valve 11, so that the sewage spraying program is automatically started when the soil ecological infiltration module 6 arrives, and automatically shut down when the soil ecological infiltration module 6 leaves.

[0030] The sewage entering the soil ecological infiltration module 6 will enter the clean water tank 17 through the liquid guide seat 5, the rotating tube 4, the liquid guide cavity 3 and the drainage pipe 27 in sequence after being purified. As the amount of clean water entering the clean water tank 17 increases, the piston float 181 will drive the scale rod 182 to move up automatically. When the experiment is over, the data on the scale rod 182 indicated by the pointer 183 can reflect the amount of clean water entering the clean water tank 17. Subsequently, the indicated data can be directly fed back to the laboratory computer through the CCD camera 21, so that the staff can directly obtain the data of this experiment. The data on the amount of seeped clean water can well feedback the permeability of the soil ecological infiltration module 6 used in this experiment, which is convenient for the experimenters to compare the standard data and adjust the soil ecological infiltration module 6, avoiding the tediousness of subsequent manual measurement of data.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
