Description

[0002] With the acceleration of urbanization, river ecosystems are facing unprecedented pressure. In particular, a large amount of pollutants, including heavy metals and organic pollutants, have accumulated in river sediments. These pollutants can also lead to eutrophication of water bodies, which in turn can cause a series of ecological problems such as algae outbreaks. Therefore, it is necessary to treat riverbed sludge.

[0003] At present, the way to treat river sludge is usually to first extract the sludge, use a filter press to filter and dehydrate it, and then carry out subsequent treatment to make the sludge meet the discharge standards. The filter press process mainly uses filter press mesh blocks for filtration. After a batch of sludge is filtered, it is necessary to suspend the operation of the entire device and desludge the sludge. After desludge is completed, new sludge can be added to continue dehydration. It is difficult to carry out desludge and sludge dehydration at the same time, resulting in poor continuity of the treatment process and low overall treatment efficiency, which makes it difficult to cope with the treatment needs of large amounts of sludge.

[0035] like Figure 2 , Figure 3 and Figure 7As shown, the filtering mechanism includes a driving motor 121, a connecting plate 122, a filter cartridge 123, a rotating shaft 124 and a connecting frame 125. The driving motor 121 is installed in the middle of the bottom of the separation cylinder 2, and the rotating shaft 124 is rotatably connected in the middle of the separation cylinder 2. The bottom of the rotating shaft 124 is connected to the output shaft of the driving motor 121, and the top of the rotating shaft 124 is connected to the middle of the bottom of the rotating cover 3. The lower part of the rotating shaft 124 is connected to the connecting plate 122, and a plurality of filter cartridges 123 are evenly spaced along the circumferential direction on the connecting plate 122. The size of the discharge port 21 is slightly larger than that of the filter cartridge 123. The filter cartridge 123 can be rotated to the top of the discharge port 21 when rotating, so that the sludge in the filter cartridge 123 can be discharged through the discharge port 21. The number of the filter cartridges 123 is consistent with the number of the injection pipes 7 and are respectively located below the corresponding injection pipes 7. The upper part of the rotating shaft 124 is connected to a connecting frame 125, and the connecting frame 125 is connected to a plurality of filter cartridges 123.

[0036] like Figure 2-Figure 7 As shown, the extrusion mechanism includes a guide sleeve 132, an extrusion bag 133, a sliding rod 134, an annular track 135, a piston plate 136 and a guide block 137. A plurality of guide sleeves 132 are rotatably connected at uniform intervals along the circumferential direction on the rotating cover 3. The number of the guide sleeves 132 is consistent with the number of the filter cartridges 123 and the lower part of the guide sleeve 132 is located in the filter cartridge 123. The outer side of the guide sleeve 132 is connected to the extrusion bag 133. The lower part of the guide sleeve 132 is evenly spaced with connecting holes 138. The connecting holes 138 connect the inside of the guide sleeve 132 with the inside of the extrusion bag 133. The inside of the guide sleeve 132 and the inside of the extrusion bag 133 are both filled with liquid. The inside of the guide sleeve 132 is slidably connected to the piston plate 136. The top of the piston plate 136 is connected to the sliding rod 134. 136 slides downward in the guide sleeve 132 to inject the liquid in the guide sleeve 132 into the squeezing bag 133 through the exhaust pipe, so that the squeezing bag 133 expands to squeeze the sludge. The piston plate 136 slides upward in the guide sleeve 132 to draw the liquid in the squeezing bag 133 back into the guide sleeve 132 through the connecting hole 138, so that the squeezing bag 133 retracts. The outer circle of the connecting frame 131 is connected to an annular track 135, and the annular track 135 is inclined with the left lower and the right higher. The top of the sliding rod 134 is connected to a guide block 137, and the guide block 137 is located in the annular track 135 and can slide along the annular track 135. When the guide block 137 slides along the annular track 135, the annular track 135 moves up and down, thereby driving the sliding rod 134 to move up and down.

[0037] like Figure 3As shown, the material discharge control mechanism includes a solenoid valve 111, a photoelectric sensor receiving end 112 and a photoelectric sensor transmitting end 113. The solenoid valve 111 is installed on the injection tube 7, and the photoelectric sensor receiving end 112 is installed on the solenoid valve 111. The photoelectric sensor transmitting end 113 is installed on the lower right side of the connection frame 131. The photoelectric sensor transmitting end 113 and the photoelectric sensor receiving end 112 constitute a photoelectric sensor. The photoelectric sensor and the solenoid valve 111 are both electrically connected to the control panel 6. The photoelectric sensor receiving end 112 is rotated to align with the photoelectric sensor transmitting end 113. At this time, the photoelectric sensor can send a signal to the control panel 6 to control the corresponding solenoid valve 111 to open.

[0038] When it is necessary to treat the sludge in the river channel, the device can be used. When in use, the sludge is first dumped into the discharge barrel 5, and the sludge in the discharge barrel 5 will enter the discharge frame 8, and the sludge in the discharge frame 8 will enter the injection pipe 7. Since the solenoid valve 111 blocks the injection pipe 7, the sludge will not continue to flow, and then the drive motor 121 can be controlled to drive the rotating shaft 124 to rotate. The rotation of the rotating shaft 124 drives the filter cartridge 123 to rotate through the connecting plate 122 and the connecting frame 125. The rotating shaft 124 can also drive the rotating cover 3 to rotate while rotating. When the rotating cover 3 rotates, it drives the injection pipe 7, the guide ring 9 and the guide sleeve 132 to rotate together. When the guide sleeve 132 rotates, it can drive the sliding rod 134 to rotate. When the sliding rod 134 rotates, it can drive the guide The block 137 slides along the circular track 135, thereby driving the piston plate 136 to move up and down. When the photoelectric sensor receiving end 112 on the injection tube 7 moves to align with the photoelectric sensor transmitting end 113, it can send a signal to the control panel 6 to control the corresponding solenoid valve 111 to open. At this time, the sludge can fall into the corresponding filter cartridge 123, and the sliding rod 134 located inside the filter cartridge 123 is also located at the top position in the guide sleeve 132, and the squeezing bag 133 is also in a contracted state. After the sludge is added, the device continues to operate, causing the corresponding photoelectric sensor receiving end 112 and the photoelectric sensor transmitting end 113 to separate. At this time, the solenoid valve 111 is closed, and then the next filter cartridge 123 will rotate to the photoelectric sensor transmitting end 113 for When the filter cartridge 123 with added sludge rotates, the guide block 137 connected to the sliding rod 134 inside the filter cartridge 123 will slide downward along the circular track 135, and the sliding rod 134 will also slide downward. When the sliding rod 134 slides downward, it can drive the piston plate 136 to move downward to inject the liquid in the guide sleeve 132 into the squeezing bag 133 through the connecting hole 138, so that the squeezing bag 133 expands to squeeze the sludge in the filter cartridge 123, and squeezes out the water in the sludge until the guide block 137 moves to the leftmost side of the circular track 135 and is also located at the bottom end of the circular track 135. Then the guide block 137 continues to move to the right along the front side of the circular track 135, so that the guide block 137 rises, thereby driving the sliding The rod 134 rises, and the sliding rod 134 draws the liquid in the squeezing bag 133 back into the guide sleeve 132 through the connecting hole 138 when rising. When the guide block 137 moves to the middle of the front side of the annular track 135, the sliding rod 134 also rises a certain distance. At this time, the squeezing bag 133 shrinks and no longer contacts the sludge, and the filter cartridge 123 also rotates to be located directly above the discharge port 21. At this time, the sludge in the filter cartridge 123 will be discharged through the discharge port 21 under the action of gravity. After being discharged, the filter cartridge 123 continues to rotate to the right side and can move to the photoelectric sensor transmitting end 113 to add sludge. This is repeated to achieve the treatment of the sludge, and in the process of treatment, it can be cyclically treated. By setting multiple filter cartridges 123 during the treatment process,The processes of sludge addition, sludge moisture extrusion and sludge discharge can be performed separately, and all processes can be carried out in sequence, and the overall treatment efficiency is higher.

[0039] like Figure 8-Figure 11 As shown, it also includes a ventilation mechanism, which includes a connecting shell 141, an air guide ring 142, an air guide pipe 143, an air injection pipe 144, an air suction pipe 145 and a partition block 146. A plurality of connecting shells 141 are evenly spaced and connected between the connecting plate 122 and the connecting frame 125. The number of the connecting shells 141 is consistent with the number of the filter cartridges 123 and is covered on the outside of the filter cartridges 123. The space between the connecting shell 141 and the filter cartridge 123 constitutes a ventilation chamber 1411. The inner bottom of the separation cylinder 2 is connected to an air guide ring 142. The inner bottom of the separation cylinder 2 is connected to partition blocks 146 on both sides. The partition blocks 146 are located at the air guide ring. 142 and slidingly cooperates with the air guide ring 142 to divide the interior of the air guide ring 142 into a front and a rear side. During the rotation of the air guide ring 142, the part located in front of the dividing block 146 is the air injection chamber, and during the rotation of the air guide ring 142, the part located behind the dividing block 146 is the air suction chamber. An air guide pipe 143 is connected between the connecting shell 141 and the air guide ring 142, and the air guide pipe 143 connects the interior of the air guide ring 142 with the interior of the connecting shell 141. An air injection pipe 144 and an air suction pipe 145 are connected on the left side of the bottom of the separation cylinder 2. The air injection pipe 144 is connected to the air injection chamber, and the air suction pipe 145 is connected to the air suction chamber.

[0040] During use, the suction pipe 145 can be connected to the suction end of the external suction device, and the injection pipe 144 can be connected to the outlet end of the air outlet device. In the process of squeezing the moisture in the sludge, the suction device causes the suction pipe 145 to inhale air, which can generate negative pressure in the suction chamber, thereby generating negative pressure in the ventilation chamber 1411 to assist in sucking out the moisture. When the squeezing bag 133 is in a contracted state after squeezing the moisture in the sludge, the air outlet device can be controlled to jet, thereby injecting gas into the injection chamber through the injection pipe 144, and the gas in the injection chamber will enter the filter cartridge 123 through the ventilation chamber 1411 and the filter holes on the filter cartridge 123, thereby assisting in pushing the sludge attached to the filter holes of the filter cartridge 123 back into the filter cartridge 123. In this way, it is possible to assist in sucking out the moisture in the sludge and push the sludge attached to the filter holes of the filter cartridge 123 back into the filter cartridge 123.

[0041] like Fig.12 and Fig.13As shown, it also includes a scraper mechanism, which includes an arc-shaped rack 151, a connecting gear 152 and a scraper frame 153. The arc-shaped rack 151 is connected to the left side of the top of the separation cylinder 2, and the connecting gear 152 is connected to the upper part of the guide sleeve 132. The arc-shaped rack 151 is located at the moving track of the connecting gear 152, so that the connecting gear 152 can rotate to mesh with the arc-shaped rack 151 and be driven to rotate by the arc-shaped rack 151. The guide sleeve 132 is connected to the scraper frame 153, and the scraper frame 153 is in contact with the inner wall of the filter cylinder 123.

[0042] When the rotating cover 3 drives the guide sleeve 132 to rotate, the guide sleeve 132 can drive the connecting gear 152 to move. When moving, the connecting gear 152 will mesh with the arc-shaped rack 151 and be driven by the arc-shaped rack 151 to rotate. At this time, the connecting gear 152 can drive the guide sleeve 132 to rotate. When the guide sleeve 132 rotates, it can drive the scraper frame 153 to rotate. The rotation of the scraper frame 153 can scrape off the sludge attached to the inner wall of the filter cartridge 123 to prevent the sludge from accumulating on the inner wall of the filter cartridge 123.

[0043] like Fig.14 and Fig.15 As shown, it also includes a connecting rod 161 and a stirring rod 162. The connecting rod 161 is connected to the middle of the top of the rotating cover 3. The upper part of the connecting rod 161 passes through the middle of the discharge frame 8 and is located in the separation cylinder 2. A plurality of groups of stirring rods 162 are evenly spaced along the circumferential direction and connected to the connecting rod 161. Each group of stirring rods 162 is provided with four stirring rods that are evenly spaced and distributed along the axial direction of the connecting rod 161.

[0044] like Fig.14 and Fig.15 As shown, a scraper plate 17 is also included. Each group of four stirring rods 162 is connected with a scraper plate 17, and the scraper plate 17 is in contact with the inner wall of the lower barrel 5.

[0045] When the rotating cover 3 rotates, it can drive the stirring rod 162 to rotate through the connecting rod 161, thereby stirring the sludge in the lower barrel 5 to prevent the sludge from condensing together. When the stirring rod 162 rotates, it can also drive the scraper plate 17 to scrape off impurities attached to the inner wall of the lower barrel 5 to prevent impurities from adhering to the inner wall of the lower barrel 5.
