Abstract
Description
Technical Field
[0001] This utility model relates to the field of separation, and in particular to a dry-wet separator. Background Technology
[0002] A wet-dry separator is a device that uses centrifugal force to separate liquids and solids in a mixture, and it has a wide range of applications in the field of waste treatment. Currently available wet-dry separators typically use a rotating screen to separate the solids from the liquid in the wastewater, and then use an auger mechanism to compact and discharge the separated solids.
[0003] Sewage dry-wet separators typically require continuous operation. During operation, sewage often flows directly into the auger mechanism without being separated. Research has found that this is because the rotating screen in the separator becomes clogged with hair and other debris from the sewage over time, reducing the screen's filtration capacity. This causes unseparated sewage to flow directly into the auger mechanism, preventing the auger from forming the product. In severe cases, this can lead to sewage overflow and create a work hazard. To solve these problems, manual cleaning and maintenance are usually used, but manual cleaning is time-consuming. Timed flushing methods cannot remove hair firmly attached to the screen, and the cleaning effect is not as expected. Using chemical flocculation to pre-treat the sewage would significantly increase the treatment cost. Utility Model Content

[0030] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0031] Please refer to Figures 1 to 5 A dry-wet separator, characterized in that it includes a rotating screen 1, a crushing component 2, a sensing component 3, and an auger component 4;
[0032] The auger assembly 4 is located at the product output end of the rotating screen 1, and the top of the auger assembly 4 is provided with a feed trough 41 for receiving the product of the rotating screen 1.
[0033] The sensing component 3 includes a moisture measuring sensor 31 and / or a liquid level sensor 32. The moisture measuring sensor 31 is located between the output end of the rotating screen 1 and the feed trough 41 and is used to sense the moisture content of the product of the rotating screen 1. The liquid level sensor 32 is located inside the feed trough 41 and is used to sense the liquid level of the feed trough 41.
[0034] The crushing component 2 is arranged around the circumference of the rotating screen 1 and is used to crush the deposits on the rotating screen 1.
[0035] As can be seen from the above description, the beneficial effects of this utility model are as follows: By combining the structural features of the dry-wet separator with the setting of sensor components and crushing components 2, the attachments on the rotating screen 1 are crushed in a timely manner. Specifically, a moisture measuring sensor 31 is set between the output end of the rotating screen 1 and the feed trough 41 of the auger assembly 4 to detect the water content of the separated product, and / or a liquid level sensor 32 is set in the feed trough 41 of the auger assembly 4 to assess the water content of the separated product by sensing the liquid level in the feed trough 41 of the auger assembly 4. When the water content reaches a set threshold, the crushing components 2 are controlled to operate to crush the attachments on the rotating screen 1, thereby clearing the screen holes on the screen, cleaning the blockage, ensuring the normal operation of the dry-wet separator, realizing automated control, and avoiding manual intervention.
[0036] Understandably, crushing component 2 can be used to crush the attached materials (mainly hair) on the screen. This can be achieved through physical crushing using sharp-faced mechanisms such as blades, or chemical crushing using degradation measures such as acid spraying. The crushing method can be selected based on the specific application environment of the dry-wet separator. Screw conveyor component 4, commonly known as a screw conveyor, is a device that uses rotating helical blades to push materials along a fixed casing for transport. This type of conveyor is mainly used for transporting powdery, granular, and small lump materials, and is suitable for horizontal, inclined, or vertical conveying. The screw conveyor typically includes a trough, helical blades, a rotating shaft, bearings at both ends, a central suspension bearing, and a drive unit. The helical blades are the core component of the screw conveyor; they rotate to move the material forward within the casing, thus achieving material transport.
[0037] Please refer to Figures 3 to 5 In an embodiment of this utility model, the crushing component 2 includes a combing plate 21, and the combing plate 21 is provided with brush plates 22 in sequence along the axial direction of the rolling screen 1. The brush plates 22 are matched with the screen holes of the rolling screen 1.
[0038] As can be seen from the above description, in order to improve the crushing effect, a combing plate 21 is set on the screen holes of the matching screen. When the rotating screen cylinder rotates, the brush plate 22 on the combing plate 21 combs the hair attached to it to an angle that is easy to cut, so as to facilitate the subsequent crushing component 2 to carry out crushing.
[0039] In an embodiment of this utility model, the crushing component 2 further includes a shearing blade 23, which is disposed tangentially to the rotating screen 1 and is used to crush the deposits on the rotating screen 1.
[0040] As can be seen from the above description, the shearing blades 23 set in the tangential direction of the rotating screen 1 are used to break up the attachments on the screen. After the combing plate 21 completes the combing function, the hair attached to the screen is broken up efficiently, while avoiding the introduction of new impurities by chemical crushing and improving the crushing efficiency.
[0041] In an embodiment of this utility model, the shearing blade 23 and the combing plate 21 are disposed adjacent to the bottom end of the rotating screen 1.
[0042] As can be seen from the above description, both the shearing blade 23 and the combing plate 21 are located at the bottom of the rotating screen 1, which has the following two advantages: First, by utilizing the weight of the attached material itself, it is easier for it to protrude from the screen surface and be more easily broken by the shearing blade 23 after combing; Second, after the shearing blade 23 breaks the attached material, it causes the attached material to directly detach from the rotating screen 1 and fall to the bottom of the device. If the breaking is carried out at other locations on the rotating screen 1, the broken hair and other attached materials are likely to fall back into the screen, causing the next blockage.
[0043] Please refer to Figure 6 In an embodiment of this utility model, a rinsing assembly 5 is further included. The rinsing assembly 5 includes a clean water tank 51 and a rinsing pipe 52. The rinsing pipe 52 includes a main pipe 53 and a nozzle 54. The main pipe 53 is arranged parallel to the axial direction of the rotating screen 1 on the outside of the rotating screen 1, and the nozzle 54 faces the screen holes of the rotating screen 1. The clean water tank 51 is used to provide rinsing water to the rinsing pipe 52.
[0044] As can be seen from the above description, after the crushing component 2 crushes the material attached to the screen, in order to quickly clear the blockage, the nozzle 54 in the flushing component 5 is used to flush and clean the screen holes, so that the cleaned debris can be quickly removed and the blockage clearing efficiency can be improved.
[0045] In an embodiment of this utility model, the rotating screen 1 includes a drive motor 6, which is used to drive the rotating screen 1 to rotate.
[0046] Furthermore, it also includes a submersible pump for conveying the waste to be treated to the input end of the rotating screen 1.
[0047] As can be seen from the above description, the drive motor 6 controls the operation of the rotating screen 1. When clearing blockages, the drive motor 6 can be paused or its operating speed reduced, simplifying the control process. At the same time, a submersible pump is used to transfer the waste to be processed to the input end of the rotating screen 1. When clearing blockages, only the submersible pump needs to be controlled to control the input amount, further simplifying the control process.
[0048] In embodiments of this utility model, a control component is also included. The control component includes a control unit, a shearing drive unit, a rinsing drive unit, and a communication unit. The control unit is used for overall control of the operation of the dry-wet separator; the shearing drive unit is used for controlling the operation of the crushing component 2; the rinsing drive unit is used for controlling the operation of the rinsing component 5; and the communication unit is used for transmitting control signals.
[0049] Specifically, please refer to Figure 7 The control unit, based on a microcontroller or PLC, includes a human-machine interface, signal acquisition board, frequency converter, and other components. It controls the motors and pumps within the device, and manages the overall operation of the device. When sensor signals are input to the control unit via the signal acquisition board, the control unit uses the obtained moisture content value at the screen output and control parameters set via the human-machine interface to control the frequency converter and other electrical components, controlling the shearing drive unit, rinsing drive unit, and other similar units.
[0050] This utility model provides a dry-wet separator, mainly used to solve the problem of screen clogging. The following is a detailed description with reference to the embodiments.
[0051] Please refer to Figures 1 to 7 Embodiment 1 of this utility model is as follows:
[0052] A dry-wet separator, characterized in that it comprises a rotating screen 1, a crushing component 2, a sensing component 3, and an auger component 4; the auger component 4 is disposed at the product output end of the rotating screen 1, and the top of the auger component 4 is provided with a feed trough 41 for receiving the product of the rotating screen 1; the sensing component 3 includes a moisture measuring sensor 31 and / or a liquid level sensor 32, the moisture measuring sensor 31 is disposed between the output end of the rotating screen 1 and the feed trough 41 and is used to sense the moisture content of the product of the rotating screen 1; the liquid level sensor 32 is disposed inside the feed trough 41 and is used to sense the liquid level of the feed trough 41; the crushing component 2 is disposed around the circumference of the rotating screen 1 and is used to crush the deposits on the rotating screen 1. A moisture sensor 31 is installed between the output end of the rotating screen 1 and the feed trough 41 of the auger assembly 4 to detect the moisture content of the separated product. And / or, a liquid level sensor 32 is installed in the feed trough 41 of the auger assembly 4 to assess the moisture content of the separated product by sensing the liquid level in the feed trough 41 of the auger assembly 4. When the moisture content reaches a set threshold, the crushing component 2 is controlled to operate to crush the deposits on the rotating screen 1, thereby clearing the screen holes on the screen, cleaning the blockage, ensuring the normal operation of the dry and wet separator, realizing automated control, and avoiding manual intervention.
[0053] Please refer to Figures 3 to 5 Embodiment two of this utility model is as follows:
[0054] Based on Embodiment 1, the crushing component 2 includes a combing plate 21, and brush plates 22 are sequentially arranged along the axial direction of the rotating screen 1 on the combing plate 21. The brush plates 22 are matched with the screen holes of the rotating screen 1. The combing plate 21 is arranged to match the screen holes on the screen. When the rotating screen cylinder rotates, the brush plates 22 on the combing plate 21 comb the hair attached to it to an angle that is easy to cut, so as to facilitate the subsequent crushing by the crushing component 2.
[0055] The crushing assembly 2 also includes a shearing blade 23, which is positioned tangentially to the rotating screen 1 and used to crush the deposits on the rotating screen 1. By using the shearing blade 23 positioned tangentially to the rotating screen 1 to crush the deposits attached to the screen, the hair attached to the screen is efficiently crushed after the combing plate 21 completes its combing function, while avoiding the introduction of new impurities through chemical crushing, thus improving crushing efficiency.
[0056] The shearing blade 23 and the combing plate 21 are positioned close to each other at the bottom of the rotating screen 1.
[0057] Please refer to Figure 6 Embodiment three of this utility model is as follows:
[0058] Based on Embodiment 1, a flushing assembly 5 is also included. The flushing assembly 5 includes a clean water tank 51 and a flushing pipe 52. The flushing pipe 52 includes a main pipe 53 and a nozzle 54. The main pipe 53 is arranged parallel to the axial direction of the rotating screen 1 on the outside of the rotating screen 1, and the nozzle 54 faces the screen holes of the rotating screen 1. The clean water tank 51 is used to provide flushing water to the flushing pipe 52. After the crushing assembly 2 crushes the material attached to the screen, in order to quickly clear the blockage, the nozzle 54 in the flushing assembly 5 is used to flush and clean the screen holes, so that the cleaned debris can be quickly removed, thereby improving the blockage clearing efficiency.
[0059] The rotating screen 1 includes a drive motor 6, which drives the rotating screen 1 to rotate. It also includes a submersible pump, which transfers waste to be treated to the input end of the rotating screen 1. By using the drive motor 6 to control the operation of the rotating screen 1, the drive motor 6 can be paused or its operating speed reduced when clearing blockages, simplifying the control process. Simultaneously, by using the submersible pump to transfer waste to the input end of the rotating screen 1, the input flow can be controlled simply by controlling the submersible pump when clearing blockages, further streamlining the control process.
[0060] Please refer to Figure 7 Embodiment four of this utility model is as follows:

When the sensor signal is input to the control unit via the signal acquisition board, the control unit controls the frequency converter and other electrical components to control the shearing drive unit, rinsing drive unit, etc., based on the obtained moisture content value at the screen output and the control parameters set by the human-machine interface.
[0062] In summary, the dry-wet separator provided by this utility model incorporates sensor and crushing components based on the structural features of the dry-wet separator to crush the deposits on the rotating screen in a timely manner.
