[0003] A search revealed that patent application CN121342291A discloses a multi-segment programmable high-voltage electric field sludge cell wall breaking device and method. This scheme sets up two electric field reaction chambers with different field strengths, which are used to break down cells with different cell wall strengths in the pretreated sludge to improve the dewatering effect of the sludge. However, in this scheme, the field strength of the electric field reaction chamber is adjusted by an electric field driving unit. The electric field driving unit includes a high-voltage electric field driver group that is independently powered, an intelligent controller for issuing control commands to the high-voltage electric field driver group, and a touch screen for real-time operation. The electric field drive unit is complex, consisting of a high-voltage driver group, an intelligent controller, and a human-machine interface. Not only are the equipment purchase and installation costs high, but daily maintenance also requires technicians with professional electrical control knowledge, which is generally lacking in the sludge treatment industry.

[0004] Therefore, it is necessary to propose a circulating electric field sludge cell disruption and lysis pretreatment device to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the existing electronic field-controlled adjustment unit is complex in structure, expensive, and requires professional personnel for maintenance, making it difficult to adapt to the actual operation and maintenance capabilities of the sludge treatment industry.

[0020] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0021] Example 1: This example discloses a circulating electric field sludge cell disruption and lysis pretreatment device, referring to... Figure 1-3 The system includes an outer shell 1, which is hollow inside. A circulation pump 2 is installed inside the outer shell 1. The input end of the circulation pump 2 is connected to a sludge inlet pipe 3. The end of the sludge inlet pipe 3 away from the circulation pump 2 extends to the outside of the outer shell 1. The output end of the circulation pump 2 is connected to a reaction pipe 4, which is fixed inside the outer shell 1. The reaction pipe 4 has a serpentine tubular structure. The end of the reaction pipe 4 away from the circulation pump 2 extends to the outside of the outer shell 1. When the circulation pump 2 is running, it draws sludge into the sludge inlet pipe 3 and then discharges the sludge into the reaction pipe 4. Finally, the sludge is discharged to the outside of the outer shell 1 through the reaction pipe 4. A top frame is fixed inside the outer shell 1. The top frame includes four horizontal plates 7, which are arranged in pairs and parallel to each other.

[0022] Reference Figure 3The outer shell 1 is equipped with an electric field cell-wall breaking component, which consists of two electric field generating structures arranged opposite each other. Each electric field generating structure includes a first DC electric field generating device 5 and a second DC electric field generating device 6. The two first DC electric field generating devices 5 and the two second DC electric field generating devices 6 are arranged opposite each other. A first reaction zone is formed between the two first DC electric field generating devices 5 and a second reaction zone is formed between the two second DC electric field generating devices 6. A reaction tube 4 passes through the first and second reaction zones. During the flow of sludge in the reaction tube 4, it will go back and forth between the first and second reaction zones multiple times, so that the electric field of the first and second reaction zones will circulate and process the sludge multiple times to ensure the dewatering effect of the sludge. The electric field strength between the first and second reaction zones can be adjusted by adjusting the distance between the two first DC electric field generating devices 5 and the two second DC electric field generating devices 6.

[0023] The first DC electric field generator 5 and the second DC electric field generator 6 have the same structure, mainly consisting of an external frame, a power supply unit, a signal modulation unit, a boost converter unit, and electrode plates. The power supply unit is connected to an external base power supply to provide electrical energy input. The signal modulation unit processes the input electrical energy and outputs a voltage waveform that meets the requirements, which is then sent to the boost converter unit to complete the voltage amplitude boost. The boosted high-voltage electrical energy is then delivered to the electrode plates. An electric field is formed between the electrode plates of the two first DC electric field generators 5. When the sludge medium to be treated flows through the area between the two electrode plates, the medium is subjected to the electric field. The cell structure is changed by means of the electroporation effect, thereby achieving the purpose of cell disruption and lysis. The first DC electric field generator 5 and the second DC electric field generator 6 are existing technologies and will not be described in detail here.

[0024] Each of the first DC electric field generating devices 5 and each of the second DC electric field generating devices 6 has a connecting seat 84 fixed at both ends. Each of the first DC electric field generating devices 5 and each of the second DC electric field generating devices 6 is provided with a sliding structure. The four horizontal plates 7 are arranged in pairs, and the four sliding structures are respectively arranged between the two pairs of horizontal plates 7. The sliding structure includes two guide rails 81 and two sliding brackets 82. The two guide rails 81 are fixed between the two horizontal plates 7 in the same group, and the two sliding brackets 82 are slidably mounted on the two guide rails 81 respectively, and the two sliding brackets 82 are respectively positioned with corresponding positions. The two connecting seats 84 on the upper are connected. For the first DC electric field generating device 5 or the second DC electric field generating device 6, the arrangement of the two guide rails 81 and the two sliding frames 82 allows them to move along the length direction of the guide rails 81, which facilitates the adjustment of the electric field strength of the first reaction zone and the second reaction zone. The guide rails 81 are arranged in the horizontal direction and are perpendicular to the horizontal plate 7. Furthermore, rollers 83 are installed on the sliding frames 82, and the number of rollers 83 is at least two. The arrangement of rollers 83 can reduce the friction between the sliding frames 82 and the guide rails 81, which facilitates the movement of the sliding frames 82 on the guide rails 81.

[0025] Each of the first DC electric field generating devices 5 and each of the second DC electric field generating devices 6 is fixed with a back support 85 on its side. Each of the back supports 85 is fixed with a fixing plate 86 on its side. The end of the fixing plate 86 away from the back support 85 is provided with an arc surface.

[0026] The housing 1 is internally equipped with two adjustment components, which act on two electric field generating structures respectively. The two adjustment components are used to adjust the distance between the two first DC electric field generating devices 5 and the two second DC electric field generating devices 6. The adjustment components include a rotation structure, a pressing structure, and a control structure. The rotation structure includes a rotating main shaft 91, which is rotatably installed inside the housing 1. One end of the rotating main shaft 91 has a channel with a circular cross-section, and the axis of the channel coincides with the axis of the rotating main shaft 91. The outer side of the rotating main shaft 91 has a strip-shaped opening 92, which communicates with the interior of the rotating main shaft 91. The rotation structure also includes a servo motor 93, which is installed inside the housing 1. The output shaft of the servo motor 93 is fixedly fitted with a first gear 94, and the rotating main shaft 91 is fixedly fitted with a second gear 95, with the first gear 94 and the second gear 95 meshing.

[0027] Reference Figure 7The pressing structure includes a sliding shaft 101, which is inserted into a channel and slidably connected to the channel. Two first pressure plates 102, one second pressure plate 103, and one third pressure plate 104 are fixed on the sliding shaft 101. The two first pressure plates 102, one second pressure plate 103, and one third pressure plate 104 all pass through the strip opening 92 and slide in the strip opening 92. A connecting plate 96 is fixed at one end of the sliding shaft 101 outside the rotating main shaft 91. The connecting plate 96 extends from the outside of the sliding shaft 101 and remains perpendicular to the sliding shaft 101.

[0028] The control structure includes a first frame 111, which is fixed inside the outer casing 1. Three reference marking lines 112 are provided on the side of the first frame 111, which correspond to three adjustment states: adjusting the first DC electric field generator 5 separately, adjusting the second DC electric field generator 6 separately, and adjusting the first DC electric field generator 5 and the second DC electric field generator 6 simultaneously. A first lead screw 113 is rotatably mounted on the first frame 111. A first movable seat 114 is threaded onto the first lead screw 113 and is slidably mounted on the first frame 111. One end of the first lead screw 113 extends to the outside of the first frame 111 and is equipped with a handwheel. The handwheel facilitates the operator's control of the rotation of the first lead screw 113.

[0029] Two annular plates 115 are fixed to the side of the first movable seat 114. There is a gap between the two annular plates 115, and the two annular plates 115 are respectively located on both sides of the connecting plate 96. When the two annular plates 115 move, they can jointly drive the connecting plate 96 to move, so that the connecting plate 96 drives the sliding shaft 101 to move. The inner diameter of the annular plate 115 is larger than the shaft diameter of the sliding shaft 101, and the annular plate 115 and the sliding shaft 101 are coaxially arranged. The sliding shaft 101 passes through the inner annular opening of the annular plate 115, and the sliding shaft 101 and the annular plate 115 do not contact each other.

[0030] Since the two electric field generating structures and the two regulating components are identical, only one of the electric field generating structures and its corresponding regulating component will be described in detail here. The regulating component has three regulating modes. First, in the initial state, such as... Figure 3 As shown, the two first pressure plates 102 are respectively positioned opposite the two fixed plates 86. In this case, when the rotating spindle 91 rotates, the two first pressure plates 102 rotate synchronously and can simultaneously apply a pushing force to the arc surface of the two fixed plates 86, so that the two fixed plates 86 move synchronously, thereby simultaneously adjusting the positions of the first DC electric field generating device 5 and the second DC electric field generating device 6.

[0031] Secondly, such as Figure 8As shown, the second pressure plate 103 is positioned directly opposite the fixed plate 86 on the first DC electric field generator 5, and the fixed plate 86 on the second DC electric field generator 6 is positioned directly opposite the gap between the third pressure plate 104 and the adjacent first pressure plate 102. In this case, when the rotating spindle 91 rotates, the second pressure plate 103 will apply a pushing force to the corresponding fixed plate 86, and the third pressure plate 104 and the two first pressure plates 102 will not contact the two fixed plates 86. At this time, the first DC electric field generator 5 moves independently, while the second DC electric field generator 6 remains stationary, and the position of the first DC electric field generator 5 can be adjusted independently.

[0032] Thirdly, such as Figure 9 As shown, the third pressure plate 104 is positioned directly opposite the fixed plate 86 on the second DC electric field generator 6, while the fixed plate 86 on the first DC electric field generator 5 is positioned directly opposite the gap between the second pressure plate 103 and the adjacent first pressure plate 102. In this case, when the rotating spindle 91 rotates, the third pressure plate 104 will apply a pushing force to the corresponding fixed plate 86, and the second pressure plate 103 and the two first pressure plates 102 will not contact the two fixed plates 86. At this time, the second DC electric field generator 6 moves independently, while the first DC electric field generator 5 remains stationary, and the position of the second DC electric field generator 6 can be adjusted independently.

[0033] In summary, by adjusting the positions of the sliding shaft 101, the first pressure plate 102, the second pressure plate 103, and the third pressure plate 104, the operator can synchronously or individually adjust the first DC electric field generator 5 and the second DC electric field generator 6, which is applicable to sludge treatment conditions in different scenarios.

[0034] For the rotating spindle 91 and the sliding shaft 101, the servo motor 93 controls their rotation. Specifically, when the servo motor 93 is running, it drives the rotating spindle 91 to rotate through the meshing first gear 94 and second gear 95. Since the first pressure plate 102, the second pressure plate 103 and the third pressure plate 104 are all placed in the strip opening 92, the rotating spindle 91 can drive the sliding shaft 101, the first pressure plate 102, the second pressure plate 103 and the third pressure plate 104 to rotate, thereby pushing and adjusting the first DC electric field generating device 5 and the second DC electric field generating device 6.

[0035] The position of the sliding shaft 101 is adjusted by a control component. Specifically, the operator controls the rotation of the first lead screw 113 by rotating a handwheel. When the first lead screw 113 rotates, it drives the first moving seat 114 to move, and the two annular plates 115 on it move accordingly. During the movement of the two annular plates 115, they can jointly drive the connecting plate 96 to move, ultimately controlling the movement of the sliding shaft 101. When the sliding shaft 101 moves, the first pressure plate 102, the second pressure plate 103, and the third pressure plate 104 move accordingly. During the adjustment process, the operator can refer to the three reference lines 112 to control the position of the sliding shaft 101, such as... Figure 10 As shown, when the middle part of the first movable seat 114 is aligned with the three reference marking lines 112 a, b, and c respectively, it corresponds to three different adjustment modes. When aligned with a, it is the synchronous adjustment mode; when aligned with b, it is the mode of adjusting the first DC electric field generator 5 separately; and when aligned with c, it is the mode of adjusting the second DC electric field generator 6 separately.

[0036] Example 2: Based on Example 1, this example discloses a circulating electric field sludge cell disruption and lysis pretreatment device, referring to... Figure 2 and Figure 5 The housing 1 is equipped with a reset assembly for controlling the reset of the first DC electric field generator 5 and the second DC electric field generator 6. The reset assembly includes a second frame 121, which is fixed inside the housing 1. A second lead screw 122 is rotatably mounted on the second frame 121. Two second moving seats 123 are threaded onto the second lead screw 122. Each second moving seat 123 is fixed with a reset push plate 125. The two reset push plates 125 are respectively positioned opposite to the two electric field generators. The two reset push plates 125 are parallel to each other and are arranged along the length of the housing 1. The second lead screw 122 has two threads of the same length but opposite directions. The two second moving seats 123 are threaded onto the two threads, which allows the second lead screw 122 to control the two second moving seats 123 to move synchronously and move away from each other when the second lead screw 122 rotates. A drive motor 124 is mounted on the side of the second frame 121. The output shaft of the drive motor 124 is fixedly connected to the second lead screw 122.

[0037] For different types of sludge, staff need to adjust the electric field strength of the first reaction zone and the second reaction zone according to the actual situation. Before each adjustment, staff can use two reset push plates 125 to control the two first DC electric field generators 5 and the two second DC electric field generators 6 to reset, so that the distance between the two first DC electric field generators 5 and the two second DC electric field generators 6 is maximized, providing a larger adjustment range for subsequent electric field adjustment. Specifically, staff can control the second lead screw 122 to rotate through the drive motor 124, thereby moving the two reset push plates 125 away from each other. When the reset push plates 125 move, they can push the side-by-side first DC electric field generators 5 and second DC electric field generators 6.

[0038] Example 3: Based on Example 2, this example discloses a circulating electric field sludge cell disruption and lysis pretreatment device, referring to... Figure 1 and Figure 2 The outer casing 1 is provided with a positioning assembly for fixing the positions of the two first DC electric field generating devices 5 and the two second DC electric field generating devices 6. The positioning assembly includes a lifting cylinder 131, a lifting frame 132 and two locking pressure plates 133. The lifting cylinder 131 is installed on the bottom surface of the outer casing 1, and the telescopic end of the lifting cylinder 131 extends into the interior of the outer casing 1 and is slidably connected to the outer casing 1. The lifting frame 132 is fixed to the telescopic end of the lifting cylinder 131. The two locking pressure plates 133 are respectively fixed to both ends of the lifting frame 132, and the two locking pressure plates 133 are respectively positioned facing the two first DC electric field generating devices 5 and the two second DC electric field generating devices 6.

[0039] After adjusting the positions of the two first DC electric field generators 5 and the two second DC electric field generators 6, the operator can activate the lifting cylinder 131, causing the lifting frame 132 to move the two locking plates 133 upward until the two locking plates 133 press down on the two first DC electric field generators 5 and the two second DC electric field generators 6. In this case, the pressing action of the two locking plates 133 can fix the two first DC electric field generators 5 and the two second DC electric field generators 6, ensuring the positional stability of the two first DC electric field generators 5 and the two second DC electric field generators 6.

[0040] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
