Description

Technical Field

[0001] This application relates to the field of sludge treatment equipment technology, specifically to an intelligent sludge dewatering system. Background Technology

[0002] To facilitate the treatment and transportation of sludge with high water content, dewatering is necessary. The dewatered, cake-like sludge is easier to bag and transport for effective processing. Common sludge dewatering methods include natural drying, mechanical dewatering, and granulation. Natural drying and mechanical dewatering are suitable for sludge-water sludge, while centrifugal dewatering is a commonly used mechanical dewatering method. In existing technologies, general sludge centrifugal dewatering equipment primarily achieves sludge dewatering by controlling the high-speed rotation of the centrifugal dewatering drum. After centrifugal dewatering, the cake-like sludge is scraped off and collected for the next batch of sludge dewatering. Most equipment relies on periodic cleaning of the filter holes on the centrifugal dewatering drum, which can lead to a decrease in dewatering efficiency due to filter hole blockage. Furthermore, the existing sludge centrifugal dewatering equipment lacks a high degree of automation, further affecting the efficiency of sludge centrifugal dewatering. Summary of the Invention

The sealing ring 45 and the sealing ring 41 are connected by several fasteners. The hollow air guide ring 310 is provided with a rotating ring 46 that is attached to the dehydration control frame 305. The rotating ring 46 slides through the cavity partition plate 315. A support member 47 is fixed between the rotating ring 46 and the sealing ring 45 and is fitted in the arc-shaped slide 312 (the synchronous rotation of the sealing ring 45 and the rotating ring 46 is achieved by the action of the support member 47). A baffle 48 is fixedly provided on the surface of the rotating ring 46. In the initial state, the baffle 48 is against the first positioning plate 313.

[0041] like Figure 6As shown, while controlling the opening of the upper solenoid valve 5 on the U-shaped air supply pipe 317, the solenoid valve 5 on the lower vent pipe 316 is also opened. At this time, the air entering the U-shaped air supply pipe 317 through the air supply pipe 318 flows upward into the inner cavity of the hollow air guide ring 310. Subsequently, the air pushes the baffle 48 to rotate counterclockwise along the inner wall of the hollow air guide ring 310 until the baffle 48 disengages from the first positioning plate 313 and abuts against the second positioning plate 314. At this time, the entire deflection and diversion assembly 4 rotates 180° counterclockwise, and the diversion pipe 43 rotates from the vertical upward position to the vertical downward position, controlling the closing of the solenoid valve 5 on the lower vent pipe 316 and the upper solenoid valve 5 on the U-shaped air supply pipe 317. When it is necessary to control the entire When the reversing flow assembly 4 completes its reset (i.e., controls the reversing flow assembly 4 to rotate clockwise), the lower solenoid valve 5 on the U-shaped air supply pipe 317 is opened, and the solenoid valve 5 on the upper vent pipe 316 is opened simultaneously. At this time, the air entering the U-shaped air supply pipe 317 through the air supply pipe 318 flows downward into the inner cavity of the hollow air guide ring 310. Subsequently, the air pushes the baffle 48 to rotate clockwise along the inner wall of the hollow air guide ring 310 until the baffle 48 disengages from the second positioning plate 314 and abuts against the first positioning plate 313. At this time, the entire reversing flow assembly 4 rotates 180° clockwise, and the flow pipe 43 rotates from the vertical downward position to the vertical upward position (i.e., the reversing flow assembly 4 returns to its initial position).

[0042] like Figure 13 As shown, a support plate 23 is fixedly installed inside the powered centrifuge cylinder 21. The output shaft of the first motor 22 passes through the hollow guide tube 42 and is fixedly connected to the support plate 23 (i.e., the output shaft of the first motor 22 and the hollow guide tube 42 are rotatably connected). Two arc-shaped flow ports 24 are opened on the surface of the support plate 23. The hollow guide tube 42 is rotatably connected to the powered centrifuge cylinder 21. The end of the hollow guide tube 42 is provided with a circular flow port 44 corresponding to the number and position of the arc-shaped flow ports 24. A solenoid valve 5 is also installed on the guide tube 43. After the powered centrifuge cylinder 21 is completed, a solenoid valve 5 is installed on the guide tube 43. After the high-moisture sludge in the inner cavity of the centrifuge cylinder 21 is transported (the high-moisture sludge in the hollow guide tube 42 flows into the inner cavity of the power centrifuge cylinder 21 through the circular flow port 44 and the arc-shaped flow port 24; after the high-moisture sludge transport is completed, the solenoid valve 5 on the guide tube 43 is controlled to close), the power centrifuge cylinder 21 is controlled by the first motor 22 to rotate at high speed to generate centrifugal force, so that the high-moisture sludge in the power centrifuge cylinder 21 can be centrifuged and dewatered. After centrifugation and dewatering, the sludge adheres to the inner wall of the power centrifuge cylinder 21 (sludge cake).

[0043] The intelligent sludge dewatering system provided in this application operates as follows: like Figure 7As shown, the control system opens the solenoid valve 5 on the drainage pipe 43, allowing high-moisture sludge to be conveyed downwards through the sludge inlet pipe 303 and the drainage pipe 43 into the inner cavity of the hollow drainage fluid 42. The high-moisture sludge entering the inner cavity of the hollow drainage fluid 42 flows into the inner cavity of the powered centrifuge drum 21 through the circular flow port 44 and the arc-shaped flow port 24. When the high-moisture sludge conveying time reaches the set time of the control system, the control system closes the solenoid valve 5 on the drainage pipe 43 and stops the conveying of high-moisture sludge. Subsequently, it opens the solenoid valve 5 on the horizontal guide pipe 307 and starts the third motor 110 to control the powered centrifuge drum 21 to rotate at high speed. The filtered water produced during the dewatering process enters the horizontal dewatering cylinder 302, and is then collected by each vertical guide pipe into the horizontal guide pipe 307. It then flows along the horizontal guide pipe 307 into the drain pipe 304 and is discharged into the collection tank (the fine sludge particles in the discharged filtered water settle in the collection tank, and the sludge that has accumulated for a long time can be further dewatered, such as by pressure filtration). During the centrifugation process, the high water content sludge in the hollow guide fluid 42 gradually flows into the inner cavity of the power centrifuge cylinder 21. During the centrifugal dewatering process, the first sealing part 113 is tightly pressed against the end of the horizontal dewatering cylinder 302 (that is, the open end of the horizontal dewatering cylinder 302 is sealed).

[0044] After the dewatering time set by the control system is reached, the first motor 22 controls the power screw 109 to rotate, causing the moving frame 111 to move horizontally away from the horizontal dewatering cylinder 302 until the moving frame 111 moves to the set position. At this time, the first sealing part 113 disengages from the opening end of the horizontal dewatering cylinder 302. Then, the power cylinder 106 controls the second mounting frame 107 to move so that the sludge output pipe 101 is aligned with the horizontal dewatering cylinder 302. Subsequently, the first motor 22 controls the power screw 109 to rotate again, causing the sludge output pipe 101 to gradually move horizontally into the inner cavity of the horizontal dewatering cylinder 302. The scraper 119 moves along the inner wall of the power centrifuge cylinder 21 to separate the attached dewatered sludge, facilitating subsequent... The circumferential movement of the scraper 119 scrapes off the dewatered sludge until the second sealing part 117 is tightly pressed against the opening end of the horizontal dewatering cylinder 302. Then, the second motor 114 controls the sludge discharge auger 102 to rotate. The sludge discharge auger 102 drives the scraper 119 to move in a circle. During the circumferential movement of the scraper 119, the dewatered sludge after being divided and crushed can be scraped off into the sludge output pipe 101 (entering into the sludge output pipe 101 through the sludge inlet 115). The dewatered sludge entering the sludge output pipe 101 is gradually transported towards the sludge discharge pipe 116 under the rotation of the sludge discharge auger 102. The sludge transported to the position of the sludge discharge pipe 116 falls into the sludge collection box through the sludge discharge pipe 116 to complete the collection.

[0045] After the sludge discharge time set by the control system is reached, the first motor 22 controls the power screw 109 to rotate in the opposite direction, causing the sludge output pipe 101 to gradually move away from the horizontal dewatering cylinder 302 until the moving frame 111 moves to the set position. At this time, the second sealing part 117 disengages from the opening end of the horizontal dewatering cylinder 302, and the scraper 119 completely disengages from the horizontal dewatering cylinder 302. Then, the power cylinder 106 controls the second mounting frame 107 to move, causing the first sealing part 113 to realign with the horizontal dewatering cylinder 302 again. The first motor 22 controls the rotation of the power screw 109, causing the first sealing part 113 to gradually approach the horizontal dewatering cylinder 302 until the first sealing part 113 is tightly pressed against the opening end of the horizontal dewatering cylinder 302. Then, the third motor 110 is turned off, and the solenoid valve 5 on the horizontal guide pipe 307 is closed while the solenoid valve 5 on the backwash pipe 309 is opened. Subsequently, the entire reversing flow diversion assembly 4 is rotated 180°, causing the diversion pipe 43 to rotate from a vertically upward position to a vertically downward position (the mud inlet pipe 303 passes through the sealing ring 4). (1. Blocking) At this time, the solenoid valve 5 on the drainage pipe 43 is opened, and backwash water is continuously delivered to the horizontal guide pipe 307 through the backwash pipe 309 (the backwash pipe 309 is connected to a backwash pump). The backwash water entering the horizontal guide pipe 307 flows upward along each vertical guide pipe into the horizontal dewatering cylinder 302. The backwash water in the horizontal dewatering cylinder 302 generates water pressure on the outer wall of the power centrifuge cylinder 21, causing the backwash water to pass through each filter hole on the power centrifuge cylinder 21 and enter the power centrifuge cylinder 21. In this way, backwashing is achieved on several filter holes on the surface of the power centrifuge cylinder 21. The backwash water in the inner cavity of the power centrifuge cylinder 21 enters the hollow guide fluid 42 through the arc-shaped flow port 24 and the circular flow port 44, and then flows downward from the hollow guide fluid 42 into the guide pipe 43, and is discharged into the water collection tank through the drain pipe 304. During this process, the inner cavity of the hollow guide fluid 42 is flushed by the backwash water, and the flushed sewage is discharged into the water collection tank. The fine sludge particles in the sewage can settle in the water collection tank.

[0046] After the backwashing time set by the control system is reached, the solenoid valve 5 on the backwash pipe 309 is closed and the backwash pump is shut off. Simultaneously, the solenoid valve 5 on the horizontal guide pipe 307 is opened. At this time, the remaining water in the inner cavities of the power centrifuge 21, the horizontal dewatering cylinder 302, and the hollow guide tube 42 is discharged into the collection tank along the vertical guide tube, the horizontal guide tube 307, and the drain pipe 304, respectively. This emptys the power centrifuge 21, the horizontal dewatering cylinder 302, and the hollow guide tube 42. After the wastewater emptying time set by the control system is reached, the solenoid valve 5 on the horizontal guide pipe 307 and the solenoid valve 5 on the guide tube 43 are first closed. Then, the reversing guide assembly 4 is rotated 180° in the opposite direction, causing the guide tube 43 to rotate from a vertically downward position to a vertically upward position (the guide tube 43 is realigned with the sludge inlet pipe 303). At this time, all components on the dewatering control mechanism return to their initial state, and all components on the multi-directional power mechanism also return to their initial state (e.g., Figure 1 As shown in the figure, the same control method described above can be used to continuously achieve automated dewatering of sludge with high water content, which improves the sludge dewatering efficiency to a certain extent.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
