Description

Technical Field

[0002] The sludge produced by municipal sewage treatment plants can be considered as a concentrate of pollutants in municipal domestic sewage. If not properly handled, it can easily cause secondary pollution. It is estimated that my country currently treats more than 220 million tons of municipal domestic sewage every day. According to the sludge yield, the national municipal sewage treatment plants produce more than 200,000 tons of sludge after filtration every day. Such a huge amount of sludge will inevitably cost a lot to handle. Therefore, exploring and studying new sludge treatment methods is an effective way to reduce sludge treatment costs and reduce secondary pollution in sludge treatment, which meets the requirements of ecological civilization construction.

[0027] In this example, see Figure 1 The above-mentioned gas collecting pipe includes a gas collecting main pipe 61 and a gas collecting branch pipe 62, wherein a first exhaust end and a second exhaust end are provided on the gas collecting main pipe 61, the first exhaust end is connected to the suction end of the stirring fan 4 through a first control valve 611, and the second exhaust end is connected to the exhaust gas treatment system through a second control valve 612. There are three gas collecting branch pipes 62, and the three gas collecting branch pipes 62 are all connected to the gas collecting main pipe 61, and the air inlet end of one of the gas collecting branch pipes 62 passes through the top of the separation cover 51 and is connected to the gas phase gathering area 103, and the other two gas collecting branch pipes 62 respectively pass through the tops of the two separation plates 52 and are connected to the gas phase gathering area 103.

The blocking component slides to block or avoid the hole 311. In application, when the working section 31 is required to perform air flow stirring operation, the blocking component slides to the first position to avoid the hole 311, so that the compressed air in the working section 31 is sprayed into the sludge pool 1 through the hole 311. When the working section 31 stops the air flow stirring operation, the blocking component slides to the second position to block the hole 311, thereby preventing sludge water from invading the working section 31 through the hole 311, thereby reducing the accident rate of sludge water blocking the working section 31.

[0030] In this example, see Figures 1 to 9 At the bottom of the sludge pool 1, a plurality of supporting columns 106 are provided along the length direction of the working section 31, and the working section 31 is fixed at the middle of the plurality of supporting columns 106.

When the electromagnet 20 is energized, the magnetic block 82 will be attracted to move toward the electromagnet, the first spring 83 will be stretched, and the magnetic block 82 will drive the driving rod 8 to move through the rotating rod 81, so that the driving rod 8 can drive the sleeve 7 to move to the first position, and the sleeve 7 avoids the hole 311. When the electromagnet 20 is powered off, the first spring 83 contracts and drives the magnetic block 82 to reset. The magnetic block 82 drives the driving rod 8 to reset through the rotating rod 81, so that the driving rod 8 can drive the sleeve 7 to move to the second position, and the sleeve 7 closes the hole 311.

[0033] In some embodiments, see Figures 1 to 9 A guide plate 75 is provided at one end of the sleeve 7 close to the hole body 311 corresponding to the hole body 311. The guide plate 75 is inclined relative to the working section 31, and the angle between the guide plate 75 and the working section 31 is an acute angle. When the sleeve 7 is in the first position on the working section 31, the guide plate 75 is located in front of the airflow injection direction in the hole body 311. The guide plate 75 is used to guide and change the transmission direction of the airflow, so that the airflow can stir the sludge water body to generate more turbulence and improve the stirring effect.

[0034] In some embodiments, see Figures 1 to 9The sleeve 7 and the working section 31 can rotate relative to each other. A square prism section 701 is provided on the side of the sleeve 7 close to the hole 311. The guide plates 75 are provided on the four side walls of the square prism section 701. The four guide plates 75 include two first plates 751 and two second plates 752. The angle between the first plate 751 and the working section 31 is different from the angle between the second plate 752 and the working section 31. The first plate 751 and the second plate 752 are arranged relative to each other. One end of 8 is connected to an intermittent driving mechanism, and a transmission assembly for driving the sleeve 7 to rotate is provided between the driving rod 8 and the sleeve 7. In this embodiment, the transmission assembly includes sprockets 73 respectively mounted on the driving rod 8 and the sleeve 7 and a chain 74 wound around the two sprockets 73. The above-mentioned intermittent driving mechanism drives the driving rod 8 to rotate intermittently, and with the help of the transmission assembly, the sleeve 7 can be driven to rotate intermittently, so that the first plate body 751 and the second plate body 752 take turns to guide the airflow ejected from the hole body 311.

[0035] Specifically, the above-mentioned intermittent drive mechanism includes a first gear 84, a half gear 85 and a motor 30, wherein the first gear 84 is arranged at the end of the driving rod 8 close to the rotating rod 81, the first gear 84 is fixedly connected to the driving rod 8, the half gear 85 is rotatably connected to the sealing plate 10 through the first rotating shaft 851, and is located on one side of the first gear 84, the motor 30 is arranged in the accommodating groove 107, and the driving end of the motor 30 is connected to the first rotating shaft 851, which is used to drive the half gear 85 to rotate. In application, when the electromagnet 20 is energized and the sleeve 7 moves to the first position, the first gear 84 moves to the predetermined position. At this time, the first gear 84 is aligned with the half gear 85, and the first gear 84 and the half gear 85 enter the working state. The motor 30 drives the half gear 85 to rotate, and the half gear 85 intermittently engages with the first gear 84 to drive the drive rod 8 to rotate intermittently, so that the drive rod 8 intermittently drives the sleeve 7 to rotate through the transmission assembly. When the electromagnet 20 is de-energized and the sleeve 7 moves to the second position, the first gear 84 and the half gear 85 are staggered, and the first gear 84 and the half gear 85 exit the working state.

[0036] In this embodiment, the number of teeth on the above-mentioned half gear 85 is 1 / 4 of the number of teeth on the above-mentioned first gear 84. Through such a configuration, the half gear 85 can drive the first gear 84 to rotate by 90° each time, so that the angle of rotation of the sleeve 7 each time is also 90°. In this embodiment, the number of hole bodies 311 corresponding to each sleeve 7 is two, and the two hole bodies 311 are respectively arranged on the left and right sides of the working section 31. When the two hole bodies 311 perform airflow stirring operation, one corresponds to the first plate body 751 or the second plate body 752. Since the first plate body 751 and the second plate body 752 have different inclination angles relative to the working section 31, the airflow ejected from the two hole bodies 311 will have different transmission angles after passing through the guide plate 75, so that the flow direction and flow rate of the sludge water body on the left and right sides of the working section 31 are different, thereby greatly increasing the turbulence in the sludge water body and improving the stirring effect. In this embodiment, two first plates 751 and two second plates 752 are provided on the square prism segment 701, and the sleeve 7 is rotated intermittently by 90°, so that the first plate 751 and the second plate 752 can correspond to each hole 311 alternately, and the airflow ejected from each hole 311 can intermittently change the transmission angle, thereby increasing the turbulence in the sludge water body and improving the stirring effect.

[0037] In some embodiments, see Figure 1 and Fig.10 A sealing sleeve 9 is provided at the end of the working section 31, and a connecting groove 901 is provided in the middle of the sealing sleeve 9. A piston 91 is slidably provided in the connecting groove 901. A second spring 93 is provided between the piston 91 and the bottom of the connecting groove 901. A proximity switch 94 is provided at the bottom of the connecting groove 901. The proximity switch 94 is used to control the opening and closing of the electromagnet 20 and the motor 30. A trigger block 92 is provided at one end of the piston 91 facing the bottom of the connecting groove 901. In application, the working section 31 is inserted into the connecting groove 901 and is sealed and connected to the connecting groove 901. The working section 31 It is connected to the connecting groove 901. When the stirring fan 4 supplies air to the working section 31, the air pressure in the working section 31 gradually increases, and the compressed air flow drives the piston 91 to move toward the side of the proximity switch 94 and compresses the second spring 93, so that the trigger block 92 triggers the proximity switch 94, thereby turning on the electromagnet 20 and the motor 30. When the stirring fan 4 stops supplying air to the working section 31, the air pressure in the working section 31 drops, and the second spring 93 contracts to drive the piston 91 to drive the trigger block 92 away from the proximity switch 94, and the electromagnet 20 and the motor 30 are turned off.

[0038] In application, when the stirring fan 4 is just started, the air pressure in the working section 31 is low. If the electromagnet 20 is in the energized state and the sleeve 7 is in the first position, the airflow ejected through the hole 311 will have insufficient power due to the low pressure, and the sludge water body will easily invade the working section 31 through the hole 311. In this embodiment, when the stirring fan 4 is turned on, the electromagnet 20 will not be energized immediately, but it is necessary to push the piston 91 through the airflow to compress the second spring after the air pressure in the working section 31 increases. 93, the electromagnet 20 will be energized only after the trigger block 92 triggers the proximity switch 94, so that the sleeve 7 avoids the hole 311. At this time, the pressure in the working section 31 is relatively large, and the airflow ejected from the hole 311 is powerful enough to prevent the sludge water from invading the working section 31 through the hole 311. On the other hand, when the air pressure in the working section 31 decreases and the airflow power is insufficient, the second spring 93 will drive the trigger block 92 away from the proximity switch 94, so that the electromagnet 20 is de-energized, so that the sleeve 7 can timely block the hole 311 on the working section 31.
