Technical Field

[0002] Most inter-basin water transfers are connected through newly built channels, but the ecosystem of the newly built channels needs a certain amount of time to reach a balanced and stable state, so there is a risk of abnormal growth of algae on the channel slopes. If the algae grow abnormally, it will affect the water supply safety, water quality safety, and engineering safety of the channel. Therefore, cleaning the algae attached to the slopes and eliminating the risks that the abnormal growth of algae may bring to the channel have become technical issues that need to be solved urgently.

[0003] At present, in the removal technology of algae growing on slopes at home and abroad, in order to avoid secondary pollution of water quality, physical removal methods are often used, mainly including manual cleaning, mechanical friction cleaning and other methods. After cleaning, the algae water needs to be separated from the algae water. However, the existing algae water separation method has cumbersome steps, low separation efficiency and poor separation effect. Therefore, a non-stop algae water separation treatment method with good separation effect, high separation efficiency and convenient operation is needed. Summary of the invention

[0010] The first return spring and the second return spring support the first wedge-shaped portion and the second wedge-shaped portion of the first vertical baffle and the second vertical baffle to extend out of the first through hole and the second through hole in a normal state; The left and right sides of the first vertical baffle and the second vertical baffle are both vertically provided with extension slides, and the left and right inner walls of the first installation box and the second installation box are both provided with extension slides corresponding to the extension slides; The middle pressure plate includes a first push plate part, a second push plate part and a push plate connecting member, the front end of the push plate connecting member is connected to the second push plate part, the rear end of the push plate connecting member is connected to the first push plate part, and the hydraulic drive motor is arranged between the first push plate part and the second push plate part.

[0011] In the initial state of step (1), the middle pressure plate is located in the middle position of the separation box in the front-to-back direction, and the sewage inlet main pipe is connected to the first sewage inlet branch pipe through the two-position three-way solenoid valve. The algae-water mixed slurry passes through the sewage inlet main pipe and the first sewage inlet branch pipe and falls to the rear side of the middle pressure plate through the first water inlet hole. The sewage of the algae-water mixed slurry is filtered by the first filter plate under the action of gravity and enters the first water filter funnel.

[0012] The specific operation process of step (2) is as follows: ① The two-position three-way solenoid valve controls the sewage inlet main pipe to be connected with the second sewage inlet branch pipe. The algae-water mixed slurry passes through the sewage inlet main pipe and the second sewage inlet branch pipe and falls to the front side of the middle pressure plate through the second water inlet hole. At the same time, the two hydraulic drive motors rotate forward, synchronously driving the gear on the same side to move backward on the rack. The middle pressure plate pushes the algae on the first water filter funnel backward, so that the algae are squeezed by the middle pressure plate and the rear pressure plate. As the first damping spring is compressed, the extrusion force on the algae becomes greater and greater, and the water contained in the algae will still be squeezed out. The sewage falls into the guide inclined plate at the bottom of the first algae box and gathers at the water outlet to be discharged from the first algae box; ② The middle pressure plate continues to move backward, pushing the rear pressure plate to continue to move backward. During the rear pressure plate's backward movement, under the action of the first wedge-shaped portion and the third wedge-shaped portion, the first vertical baffle moves downward to compress the first return spring until the rear pressure plate moves to the rear side of the first vertical baffle. At this time, the first vertical baffle returns to its original position upward under the action of the first return spring. ③ Then the hydraulic drive motor rotates in the opposite direction, driving the middle pressure plate to move forward, and the rear pressure plate is supported by the first vertical baffle plate. The algae between the middle pressure plate and the rear pressure plate are no longer subjected to the squeezing force and naturally fall into the first algae box.

[0013] The specific operation process of step (3) is as follows: ① The two hydraulic drive motors rotate in opposite directions, synchronously driving the gear on the same side to move forward on the rack, so that the middle pressure plate continues to move forward. When the middle pressure plate moves to its original position, the two-position three-way solenoid valve controls the sewage inlet main pipe to be connected with the first sewage inlet branch pipe again. The algae-water mixed slurry passes through the sewage inlet main pipe and the first sewage inlet branch pipe and falls to the front side of the middle pressure plate through the first water inlet hole. At the same time, the hydraulic drive motor continuously drives the middle pressure plate forward, so that the algae are squeezed by the middle pressure plate and the front pressure plate. As the second damping spring is compressed, the extrusion force on the algae becomes greater and greater, and the water contained in the algae will still be squeezed out. The sewage falls into the guide inclined plate at the bottom of the second algae box and is collected at the water outlet to be discharged from the second algae box. ② The middle pressure plate continues to move forward, pushing the front pressure plate to continue to move forward. During the forward movement of the front pressure plate, under the action of the second wedge-shaped portion and the fourth wedge-shaped portion, the second vertical baffle moves downward to compress the second return spring until the front pressure plate moves to the front side of the second vertical baffle. At this time, the second vertical baffle returns to its original position under the action of the second return spring; ③ Then the hydraulic drive motor rotates forward, and the hydraulic drive motor drives the middle pressure plate to move backward. The front pressure plate is supported by the second vertical baffle plate. The algae between the middle pressure plate and the front pressure plate are no longer subjected to the squeezing force and naturally fall into the second algae box.

[0014] When the hydraulic drive motor drives the middle pressure plate to move forward and the rear pressure plate is supported by the first vertical baffle, the first hydraulic telescopic oil cylinder pushes the second wedge block to move forward, and the second wedge block presses down the seventh wedge surface of the first mounting hole to make the first vertical baffle move down again, and the rear side surface of the upper end of the first vertical baffle is separated from the front side surface of the lower end of the rear pressure plate, and the rear pressure plate slowly returns to its original position forward under the action of the first damping spring; When the middle pressure plate moves backward and the front pressure plate is supported by the second vertical baffle, the second hydraulic telescopic cylinder extends, pushing the fourth wedge block to move backward. The fourth wedge block presses down the third wedge block to make the second vertical baffle move down again. The front pressure plate slowly returns to its original position backward under the action of the second damping spring.

[0015] The algae-water separation device of the present invention drives the middle pressure plate to reciprocate forward and backward through the forward and reverse rotation of the hydraulic drive motor to push the algae on both sides thereof so that the water in the algae is squeezed out and sent to the algae box, thereby effectively improving the algae-water separation efficiency and separation effect.

[0016] In summary, the present invention is easy to operate, simplifies the algae-water separation process, greatly improves the algae-water separation efficiency and separation effect, and effectively solves the technical problems of the existing separation methods with complicated steps, low separation efficiency and poor separation effect.

[0031] In the initial state in step (1), the intermediate pressure plate 51 is located in the middle position of the separation box 44 in the front-to-back direction, and the sewage inlet main pipe 103 is connected to the first sewage inlet branch pipe 101 through the two-position three-way solenoid valve 104. The algae-water mixed slurry passes through the sewage inlet main pipe 103 and the first sewage inlet branch pipe 101 and falls to the rear side of the intermediate pressure plate 51 through the first water inlet hole 55. The sewage of the algae-water mixed slurry is filtered by the first filter plate 48 under the action of gravity and enters the first water filter funnel 46.

[0032] The specific operation process of step (2) is as follows: ① The two-position three-way solenoid valve 104 controls the sewage inlet main pipe 103 to be connected with the second sewage inlet branch pipe 102. The algae-water mixed slurry passes through the sewage inlet main pipe 103 and the second sewage inlet branch pipe 102 and falls to the front side of the intermediate pressure plate 51 through the second water inlet hole 56. At the same time, the two hydraulic drive motors rotate forward, synchronously driving the gear 60 on the same side to move backward on the rack 62, and the intermediate pressure plate 51 pushes the algae on the first water filter funnel 46 backward to move, so that the algae are squeezed by the intermediate pressure plate 51 and the rear pressure plate 50. As the first damping spring 53 is compressed, the extrusion force on the algae becomes greater and greater, and the water contained in the algae will still be squeezed out. The sewage falls into the guide inclined plate 99 at the bottom of the first algae box 45, and is collected at the water outlet 100 to be discharged from the first algae box 45; ② The middle pressure plate 51 continues to move backward, pushing the rear pressure plate 50 to continue to move backward. During the rear pressure plate 50 moving backward, under the action of the first wedge-shaped portion and the third wedge-shaped portion, the first vertical baffle 67 moves downward to compress the first return spring 63 until the rear pressure plate 50 moves to the rear side of the first vertical baffle 67. At this time, the first vertical baffle 67 returns to its original position upward under the action of the first return spring 63. ③ Then the hydraulic drive motor rotates in the opposite direction, and the hydraulic drive motor drives the middle pressure plate 51 to move forward. The rear pressure plate 50 is supported by the first vertical baffle 67. The algae between the middle pressure plate 51 and the rear pressure plate 50 are no longer subjected to the squeezing force and naturally fall into the first algae box 45.

[0033] The specific operation process of step (3) is as follows: ① The two hydraulic drive motors rotate in opposite directions, synchronously driving the gear 60 on the same side to move forward on the rack 62, so that the intermediate pressure plate 51 continues to move forward. When the intermediate pressure plate 51 moves to its original position, the two-position three-way solenoid valve 104 controls the sewage inlet main pipe 103 to be connected with the first sewage inlet branch pipe 101 again, and the algae-water mixed slurry passes through the sewage inlet main pipe 103 and the first sewage inlet branch pipe 101 and falls to the front side of the intermediate pressure plate 51 through the first water inlet hole 55. At the same time, the hydraulic drive motor continuously drives the intermediate pressure plate 51 forward, so that the algae are squeezed by the intermediate pressure plate 51 and the front pressure plate 52. As the second damping spring 54 is compressed, the extrusion force on the algae becomes greater and greater, and the water contained in the algae will still be squeezed out. The sewage falls into the guide inclined plate 99 at the bottom of the second algae box 96, and is collected at the water outlet 100 to be discharged from the second algae box 96; ② The middle pressure plate 51 continues to move forward, pushing the front pressure plate 52 to continue to move forward. During the forward movement of the front pressure plate 52, under the action of the second wedge-shaped portion and the fourth wedge-shaped portion, the second vertical baffle 68 moves downward to compress the second return spring 64 until the front pressure plate 52 moves to the front side of the second vertical baffle 68. At this time, the second vertical baffle 68 returns to its original position under the action of the second return spring 64. ③ Then the hydraulic drive motor rotates forward, and the hydraulic drive motor drives the middle pressure plate 51 to move backward. The front pressure plate 52 is supported by the second vertical baffle 68. The algae between the middle pressure plate 51 and the front pressure plate 52 are no longer subjected to the squeezing force and naturally fall into the second algae box 96.

[0034] When the hydraulic drive motor drives the middle pressure plate 51 to move forward and the rear pressure plate 50 is supported by the first vertical baffle 67, the first hydraulic telescopic oil cylinder 69 pushes the second wedge block 108 to move forward, and the second wedge block 108 presses down the seventh wedge surface of the first mounting hole 105 to make the first vertical baffle 67 move down again, and the upper rear side surface of the first vertical baffle 67 is separated from the lower front side surface of the rear pressure plate 50, and the rear pressure plate 50 slowly returns to its original position forward under the action of the first damping spring 53; While the middle pressure plate 51 moves backward and the front pressure plate 52 is supported by the second vertical baffle 68, the second hydraulic telescopic cylinder 70 extends, pushing the fourth wedge block to move backward.

8. The non-stop algae-water separation method according to claim 7, characterized in that: The specific operation process of step (2) is as follows: ① The two-position three-way solenoid valve controls the sewage inlet main pipe to be connected with the second sewage inlet branch pipe. The algae-water mixed slurry passes through the sewage inlet main pipe and the second sewage inlet branch pipe and falls to the front side of the middle pressure plate through the second water inlet hole. At the same time, the two hydraulic drive motors rotate forward, synchronously driving the gear on the same side to move backward on the rack. The middle pressure plate pushes the algae on the first water filter funnel backward, so that the algae are squeezed by the middle pressure plate and the rear pressure plate. As the first damping spring is compressed, the extrusion force on the algae becomes greater and greater, and the water contained in the algae will still be squeezed out.

The algae-water mixed slurry passes through the sewage inlet main pipe and the first sewage inlet branch pipe and falls to the front side of the middle pressure plate through the first water inlet hole. At the same time, the hydraulic drive motor continuously drives the middle pressure plate forward, so that the algae are squeezed by the middle pressure plate and the front pressure plate. As the second damping spring is compressed, the extrusion force on the algae becomes greater and greater, and the water contained in the algae will still be squeezed out. The sewage falls into the guide inclined plate at the bottom of the second algae box and is collected at the water outlet to be discharged from the second algae box. ② The middle pressure plate continues to move forward, pushing the front pressure plate to continue to move forward. During the forward movement of the front pressure plate, under the action of the second wedge-shaped portion and the fourth wedge-shaped portion, the second vertical baffle moves downward to compress the second return spring until the front pressure plate moves to the front side of the second vertical baffle. At this time, the second vertical baffle returns to its original position under the action of the second return spring; ③ Then the hydraulic drive motor rotates forward, and the hydraulic drive motor drives the middle pressure plate to move backward.
