Description

Technical Field

[0001] The utility model relates to the technical field of green algae cleaning equipment, in particular to an automatic cleaning device for an algae blocking net frame. Background Art

[0002] In open channel water transfer, each water inlet is typically equipped with two gates for easy maintenance. To prevent large amounts of green algae from being released downstream, an algae barrier is installed between the two gates. Each algae barrier requires four algae-blocking frames assembled within a single frame. During water release, algae accumulates on the frames, and in severe cases, they can completely clog and clog the frames, leading to water outages. Therefore, the frames must be regularly cleaned to ensure proper operation. Due to space constraints, the frames must be manually removed one by one, cleaned manually, and then reinstalled within the frame, repeating this process over and over again. This operation is inefficient and labor-intensive. Furthermore, the manually cleaned algae and water mixture must be stored in a fixed area, wasting resources and increasing labor, while also causing secondary pollution to the surrounding environment.

[0022] Combine Figures 1 to 3 As shown, an automatic cleaning device for an algae intercepting net frame includes a box body 1 with a frame structure, the box body 1 is provided with box walls on all sides, the top of the box body 1 is provided with a conveying port 11 open upward, the bottom of the box body 1 is provided with a sewage collecting port 12, a rotating brush 2 is passed through the box body 1, one end of the rotating brush 2 is connected to a motor 21, the motor 21 is fixedly connected to the box body 1, two groups of rotating brushes 2 are provided in parallel and rolling against each other, the two groups of rotating brushes 2 are respectively provided on both sides of the inner side of the conveying port 11, and the opening plane of the conveying port 11 is parallel to the length direction of the rotating brush 2.

[0023] The length of the rotating brush 2 is parallel to the conveying direction of the conveyor 3. A gantry 13 is located above the conveying port 11, with a suspension device 14 located at its top. Limiting slots 15 are provided on either side of the conveying port 11 along its length within the housing 1. These slots are located below the gantry 13, allowing the algae-blocking screen 5, which is being cleaned, to move vertically within the conveying port 11 along these slots. Below the sewage collection port 12 is the conveyor 3, with a filter press located at its output end. This filter press includes a pressure roller 4 located above the output end of the conveyor 3.

[0024] Combine Figures 1 to 4 As shown, the conveyor 3 is a belt conveyor, and a lower fixed roller 30 is provided on the inner side of the conveyor belt of the conveyor 3. The lower fixed roller 30 can be replaced by the tensioning rollers at both ends of the belt conveyor or can be provided separately. The pressure roller 4 in the filter press is provided on the upper part of the position corresponding to the lower fixed roller 30. A pressure adjustment mechanism is provided between the pressure roller 4 and the conveyor 3. The pressure adjustment mechanism includes a fixed guide groove 31 and a guide body 41 sliding in the guide groove 31. The guide body 41 is provided with two shaft ends respectively provided at the pressure roller 4. The pressure roller 4 is rotatably connected to the guide body 41 through a double-row spherical roller bearing 42. Both sides of the guide body 41 are slidably provided in the guide groove 31. The sliding direction of the guide body 41 is consistent with the conveyor The conveying plane of the conveyor 3 is vertical, and two sets of guide grooves 31 are respectively fixed on the left and right sides of the conveying direction of the conveyor 3. A fixed block 32 is provided at the bottom of the guide groove 31 in the length direction, and a pressure-adjusting bolt 34 is provided between the guide body 41 and the fixed block 32. The top threaded end of the pressure-adjusting bolt 34 is threadedly connected to the guide body 41, and the middle part of the pressure-adjusting bolt 34 is slidably passed through the fixed block 32. A compressible spring 33 is provided between the bottom surface of the fixed block 32 and the nut at the bottom end of the pressure-adjusting bolt 34. The lower side of the guide body 41 is threadedly connected to one end of the limiting screw 35, and the bottom end of the limiting screw 35 is top-connected to the upper side of the fixed block 32. The minimum height of the pressure roller 4 is adjusted by the set limiting screw 35.

[0025] The pressure adjustment mechanism has two functions: upper and lower pressure adjustment and upper and lower minimum distance adjustment: First, by adjusting the upper and lower positions of the pressure-adjusting bolt 34, the compression amount of the spring 33 is adjusted, and then the pressure between the pressure roller 4 and the lower fixed roller 30 is adjusted, so as to adjust the extrusion force of the filter press device; Second, in order to limit the damage to the belt caused by direct contact between the upper and lower pressure rollers when no-load, it is necessary to limit the minimum distance between the upper and lower rollers. Since the upper roller naturally has a tendency to move downward under its own weight, two limit screws 35 are added. When necessary, the elongation of the limit screw 35 can be adjusted to achieve the purpose of adjusting the minimum distance between the pressure roller 4 and the lower fixed roller 30.

[0026] During use, the operator hangs the algae-catching net frame 5 with attached green algae on the suspension device 14 above the box body 1. Then, the operator controls the suspension device 14 to slowly lower the algae-catching net frame 5. The limit and guidance of the sliding of the algae-catching net frame 5 are realized through the provided limit groove 15, making the up-and-down movement of the algae-catching net frame 5 smoother and avoiding jamming. At the same time, the motors 21 drive the two rotating brushes 2 to rotate respectively, and the rotational speeds of the two motors 21 can be adjusted by the frequency converter. The conveyor 3 also starts working simultaneously. The rotating brushes 2 clean the green algae attached to the algae-catching net frame 5. Part of the green algae directly falls onto the conveyor belt of the conveyor 3 below, and part of the green algae adheres to the rotating brushes 2. However, under the action of the high-speed rotation centrifugal force of the rotating brushes 2, the green algae is thrown out and finally also falls onto the conveyor belt below and is sent out by the conveyor 3 together. While the conveyor 3 sends out the green algae, the pressing rollers 4 of the pressure filtration device and the conveyor belt jointly squeeze the green algae on the conveyor belt to squeeze out the excess water in the green algae, realizing the separation of water and green algae. After the algae-catching net frame 5 reaches the lowest position from top to bottom, the suspension device 14 starts to drive the algae-catching net frame 5 to move upward. The dirt on the algae-catching net frame 5 can be washed synchronously through a water pipe to complete further washing work. After the algae-catching net frame 5 reaches the highest position, all the motion systems stop working. The operator removes the algae-catching net frame 5 and installs the cleaned algae-catching net frame 5 back into the frame of the algae-catching device, and the entire cleaning work of the algae-catching net frame completes a cycle.

[0027] The water squeezed out by the pressure filtration device can be used to irrigate green plants. The green algae after pressure filtration is convenient for shipping and centralized drying, and the dried green algae can be used as fertilizer. In this way, resources are effectively utilized, the labor intensity of the operator is reduced, and secondary pollution to the environment is avoided.

[0032] During use, as shown in Figures 5 to 7 , the algae-catching net frame 5 to be cleaned is horizontally pushed from the conveying port 11 to the output port 110 at the other end. At the same time, the two sides of the algae-catching net frame 5 are cleaned by the rotating brush 2. By rotating the positioning screw 63, the height of the adjustment frame 60 in the box body 1 can be adjusted, and then the lifting height of the idlers 6 for supporting the algae-catching net frame 5 can be adjusted, so as to adapt to the cleaning of algae-catching net frames 5 with different heights. In order to further improve the cleaning ability, the brush 2 at the output port 110 can clean the algae-catching net frame 5 again. In this embodiment, the algae-catching net frame 5 does not need to be lifted to a relatively high height, which is suitable for cleaning algae-catching net frames 5 with more attached green algae.
