Description

Technical Field

[0001] This utility model relates to the field of plastic microbial degradation technology, specifically to a device for degrading plastics using microorganisms. Background Technology

[0002] For example, Chinese patent CN211255786U discloses a device for degrading plastics using microorganisms, including a degradation cylinder. A first support plate is fixedly welded to the side wall of the degradation cylinder. A blower is fixedly installed at the upper end of the first support plate. A connecting pipe is provided at the lower end of the degradation cylinder. The air outlet of the blower is connected to the connecting pipe through an air pipe. One end of the connecting pipe passes through the lower end of the degradation cylinder and is connected to an aeration pipe. A second support plate is fixedly welded to the side wall of the degradation cylinder.

[0003] However, the above solution has the following shortcomings: The above technology, by setting up a blower and an aeration pipe, connecting the blower's outlet to the aeration pipe, and connecting microporous aerators at equal intervals on the aeration pipe, can oxygenate the biodegradation liquid during plastic degradation through the blower and microporous aerators. However, during use, when the degradation work is paused, the EPS secreted by the bacterial flocs in the biodegradation liquid will adhere to the microporous aerator like glue along with impurities, clogging the micropores in the aerator and preventing the aerator from aerating and oxygenating. Therefore, we have introduced a device that utilizes microorganisms to degrade plastic. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution:

[0021] Example 1:

[0022] A device for degrading plastics using microorganisms includes a degradation tank 1. Both ends of the degradation tank 1 are equipped with movable aeration mechanisms. The movable aeration mechanisms increase oxygen into the degradation tank 1, which to a certain extent improves the biological activity in the biodegradation liquid and increases the degradation speed. Both ends of the degradation tank 1 are fixedly connected to a cleaning water tank 4, which contains a water source. The water source is transferred to the cleaning water tank 4 by rotating the aeration side of the movable aeration mechanism. The movable aeration mechanism is connected to a conversion mechanism.

[0023] The conversion mechanism is located at the lower end of the cleaning water tank 4. An air pump 11 is fixedly installed at the lower end of the degradation tank 1. The conversion mechanism is connected to the output end of the air pump 11 through the air guide pipe 5. A circulation filtration mechanism is provided on the outside of the degradation tank 1. The degradation liquid is circulated and filtered through the circulation filtration mechanism. Several vibrators 14 are fixedly installed inside the cleaning water tank 4. The specific model of the vibrator 14 is the BJ-50 ultrasonic transducer produced by Guangdong Gute Technology Co., Ltd. The vibrator 14 uses high-frequency vibration to generate dense micro bubbles in the liquid. When these bubbles collapse instantly, they release energy to physically impact and micro-scrub the microporous aerator 12 immersed in the liquid.

[0024] The movable aeration mechanism includes a connecting pipe 7, which is open at the lower end and sealed at the upper end. The connecting pipe 7 is movably connected to the mounting cavity 13, which is located inside the degradation chamber 1. The outer side of the connecting pipe 7 is tightly fitted to the mounting cavity 13. Several microporous aerators 12 are fixedly installed on one side of the connecting pipe 7. The upper end of the connecting pipe 7 is fixedly connected to the output end of the drive motor 6, which is fixedly installed on the upper end of the degradation chamber 1. The lower end of the connecting pipe 7 is movably connected to a sliding pipe 10, which is fixedly connected to a three-way solenoid valve 9. When it is necessary to clean several microporous aerators 12, the corresponding drive motor 6 is turned on to drive the connecting pipe 7 to rotate. Since the sliding pipe 10 is slidably connected to the lower end of the connecting pipe 7, the sliding pipe 10 will not rotate during the rotation of the connecting pipe 7. After the connecting pipe 7 drives several microporous aerators 12 into the cleaning water tank 4, the drive motor 6 stops rotating and self-locks.

[0025] The conversion mechanism includes a three-way solenoid valve 9. A first circulation pump 8 is fixedly installed at the lower end of the cleaning water tank 4. The input end of the first circulation pump 8 extends into the cleaning water tank 4, and the output end is fixedly connected to the three-way solenoid valve 9. The three-way solenoid valve 9 is also fixedly connected to the air guide pipe 5. The cleaning filtration mechanism includes a second circulation pump 2. The output end of the second circulation pump 2 extends into the degradation chamber 1 and is connected to the output end of the filter 3. The input end of the filter 3 extends into the degradation chamber 1. The filter 3 can be selected in appropriate size and model during use.

[0026] Working principle: During use, the three-way solenoid valve 9 connects the air guide pipe 5 to the sliding pipe 10 without connecting it to the first circulation pump 8. The air pump 11 sends gas into the two air guide pipes 5. The gas entering the air guide pipes 5 will pass through the three-way solenoid valve 9 into the sliding pipe 10. The gas will then pass through the sliding pipe 10 into the connecting pipe 7. The gas entering the connecting pipe 7 will pass through several microporous aerators 12 into the degradation chamber 1. This oxygenates the biodegradation liquid during plastic degradation, which to some extent improves the biological activity in the biodegradation liquid and increases the degradation speed.

[0027] The liquid in the degradation tank 1 is pumped into the filter 3 by the second circulation pump 2. The filter 3 filters out impurities in the liquid. The filtered liquid returns to the degradation tank 1 through the output of the second circulation pump 2. When it is necessary to clean several microporous aerators 12, the corresponding drive motor 6 is turned on to drive the connecting pipe 7 to rotate. Since the sliding pipe 10 is slidably connected to the lower end of the connecting pipe 7, the sliding pipe 10 will not rotate with the connecting pipe 7 during the rotation. After the connecting pipe 7 drives several microporous aerators 12 into the cleaning water tank 4, the drive motor 6 stops rotating and self-locks.

[0028] The three-way solenoid valve 9 is controlled to connect the first circulation pump 8 to the sliding pipe 10. The air guide pipe 5 is not connected to the first circulation pump 8 or the sliding pipe 10. After the first circulation pump 8 is started, the water in the cleaning water tank 4 is drawn into the connecting pipe 7 and then discharged into multiple microporous aerators 12. At the same time, the vibrator 14 located in the cleaning water tank 4 will cause the water in the cleaning water tank 4 to vibrate, which facilitates the cleaning of impurities in the microporous aerators 12. After cleaning, the first circulation pump 8, vibrator 14, etc. are turned off, and the microporous aerators 12 are rotated back into the degradation box 1 by the drive motor 6 driving the connecting pipe 7.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
