Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, and in particular to an adaptive energy-saving rotary bar screen cleaner. Background Technology

[0002] A bar screen is a type of wastewater treatment machine that separates solids from liquids using a bar screen. It is used to automatically intercept, collect, and discharge solid impurities from wastewater.

[0003] During operation, the motor drives the active guide wheel to rotate, which in turn drives the chain and the driven guide wheel located in the underwater working area. The sprocket has several rake teeth, which hook underwater debris and move it upwards with the movement of the sprocket. The debris is then removed by gravity and transported to the conveying device, which removes the debris. However, existing rotary bar screens cannot automatically adjust the rotation speed according to the amount of solid impurities in the water. There is a problem that the rotation speed is not matched with the amount of solids intercepted. When there are few solid impurities, the rotation speed is too fast and idles, which increases the overall energy consumption. Or when there are many solid impurities, the rotation speed is too slow, which can cause the impurities to accumulate and block the water. In addition, the existing plow-type rake teeth are all fixed and cannot be adjusted according to the amount of solid impurities intercepted. When rakes are rake, if the rake teeth are too long and the single load is too large, the transmission chain is prone to breakage at high speed. If the rake teeth are too short, the amount of debris retrieved at one time is too small, resulting in low bar screen removal efficiency.

[0004] Therefore, it is necessary to provide a new adaptive energy-saving rotary bar screen to solve the above-mentioned technical problems. Summary of the Invention

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0038] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0039] Example 1:

[0040] Please see Figures 1 to 9 The present invention provides an adaptive energy-saving rotary bar screen cleaner, which includes: a support frame 1 and multiple transmission sprockets 11 rotatably mounted on both sides of the support frame 1. A transmission chain 12 is mounted on the multiple transmission sprockets 11 located on the same side. Multiple support rollers 13 are evenly installed between two transmission chains 12. A hollow tube 14 is installed between two corresponding transmission sprockets 11 on the same side. The hollow tube 14 is coaxial with the rotation shaft of the transmission sprocket 11. Protective baffles 15 are also installed on both sides of the support frame 1.

[0041] The drive mechanism 2, which drives the transmission sprocket 11 to rotate, is mounted on the support frame 1. The drive mechanism 2 is electrically connected to the controller 2a, and the controller 2a is electrically connected to multiple vision cameras 2b. The drive mechanism 2 includes a mounting plate 21, which is mounted on the top of the support frame 1. A drive motor 22 and a reducer 23 are sequentially mounted on the mounting plate 21. The output shaft of the drive motor 22 is coaxially and fixedly connected to the input shaft of the reducer 23. The output shaft of the reducer 23 is connected to the support shaft of the transmission sprocket 11 on the top side through a pulley. Both the drive motor 22 and the reducer 23 are electrically connected to the controller 2a, which is mounted on the mounting plate 21. Multiple vision cameras 2b are mounted on the front and rear ends of the mounting plate 21.

[0042] A grid component 3 is provided in several units, and the grid components 3 are continuously and alternately arranged on two adjacent support rollers 13. The grid component 3 includes a spacer rod 31, on which several grid pieces 32 are evenly installed. Both ends of the grid pieces 32 are provided with round holes 301 that slide with the support rollers 13. Plow claws 33 are movably inserted between two adjacent grid pieces 32 on the spacer rod 31. Multiple plow claws 33 are evenly provided with multiple limiting holes 303. The bottom ends of multiple plow claws 33 are connected to a base plate 331. Insertion holes 302 aligned with the limiting holes 303 are provided on the spacer rod 31 at positions corresponding to the multiple plow claws 33. Limiting components 34 are movably inserted into the insertion holes 302 on the spacer rod 31. Adjustment rod seats 311 are threadedly installed on both ends of the spacer rod 31.

[0043] The adjustment mechanism 4 is embedded in the hollow tube 14 at the top and back of the support frame 1. The adjustment mechanism 4 includes an installation tube 41, which is embedded in the hollow tube 14 and is coaxially arranged with the hollow tube 14. Multiple lifting parts 42 are installed at both ends of the installation tube 41. Each of the multiple lifting parts 42 is equipped with an adjustment part 43 for adjusting the extension and retraction of the plow claw 33. The multiple lifting parts 42 and the adjustment parts 43 are electrically connected to the controller 2a.

[0044] It should be noted that during use, when the support frame 1 is installed on the intercepting water area, the visual camera 2b captures and identifies the solid floating impurities in the water at the front end of the cleaning machine, as well as the solid impurities dredged by the grid piece 3 that has just emerged from the water area. Based on the identified quantity, the information is fed back to the controller 2a. The controller 2a adjusts the speed of the drive motor 22 of the drive mechanism 2 according to the feedback information, thereby adjusting the overall operating speed of the cleaning machine to avoid idling or blockage caused by excessively slow speed, making the cleaning machine more efficient and energy-saving.

[0045] Furthermore, based on the identification of solid impurities in the water body through the shooting, when several grid pieces 3 pass through the adjustment mechanism 4, the lifting piece 42 first releases the restriction of the limiting piece 34 on the multiple plow claws 33 by the adjusting piece 43, and then the adjusting piece 43 cooperates with the base plate 331 to adjust the extension length of the plow claws 33, thereby adjusting the retrieval load of a single rotation of the cleaning machine. This reduces the retrieval load at high speed to avoid breakage of the transmission chain 12, and maximizes the single retrieval load at low speed, making the entire cleaning machine more efficient and energy-saving.

[0046] It should also be noted that: both controller 2a and vision camera 2b are control and monitoring components commonly used in existing industrial technology. By capturing images and then using image algorithms, they can analyze the content of solid impurities in the water and feed the analysis results back to controller 2a. Controller 2a, through programming using a microcontroller or PLC logic device, can control the drive mechanism 2 and the adjustment mechanism 4 to perform corresponding actions based on the feedback results. The specific control principle will not be described in detail here.

[0047] In an embodiment of the present invention, please refer to Figure 1 , Figure 4 and Figure 9 The limiting member 34 includes a vertical plate 341. The top of the vertical plate 341 is equipped with mounting pieces 342 corresponding to multiple insertion holes 302. A limiting rod 343 is fixedly installed on the end of the mounting piece 342 facing the insertion hole 302. The limiting rod 343 is inserted and engaged with the corresponding insertion hole 302. A return spring 344 is symmetrically installed on the end of the mounting piece 342 facing the insertion hole 302. The end of the return spring 344 away from the mounting piece 342 is fixedly connected to the outer wall of the spacer rod 31. A limiting frame 345 is installed on the top of the mounting piece 342. A filter screen 346 is embedded in the limiting frame 345.

[0048] It should be noted that when the limiting member 34 is in use, when multiple plow claws 33 are inserted into the spacer rod 31, the limiting rod 343 corresponding to the multiple plow claws 33 is first passed through the insertion hole 302 and then inserted into the limiting hole 303 on the corresponding plow claw 33 to complete the limiting and locking. When adjustment is required, the vertical plate 341 is pulled outward to drive the limiting rod 343 from the limiting hole 303 into the insertion hole 302. After adjustment, after the limiting hole 303 is aligned with the insertion hole 302, the vertical plate 341 is released. Under the action of multiple return springs 344, the vertical plate 341 is pulled to automatically drive the limiting rod 343 to return and insert into the limiting hole 303.

[0049] In this embodiment: a rectangular protective cover 35 is installed on the side of the spacer rod 31 away from the limiting member 34 and corresponding to the multiple insertion holes 302. The rectangular protective cover 35 is designed with a hollow structure, and a discharge hole 351 is opened at the bottom of the rectangular protective cover 35. This makes it easy for the rectangular protective cover 35 to protect the insertion holes 302 and prevent impurities from entering the insertion holes 302. At the same time, the discharge hole 351 is provided to facilitate the expulsion of impurities in the limiting hole 303 from the discharge hole 351 when the limiting rod 343 is inserted into the limiting hole 303, thus preventing the limiting hole 303 from being blocked.

[0050] In an embodiment of the present invention, please refer to Figure 1 , Figure 5 , Figure 6 and Figure 7 Multiple lifting components 42 are circumferentially distributed around the axis of the hollow tube 14. Each lifting component 42 includes a screw 421 and a servo motor 423. The screw 421 is rotatably mounted on the mounting tube 41. A rectangular rod 422 is threadedly connected to one end of the screw 421 that passes outward through the mounting tube 41. One end of the rectangular rod 422 passes upward through a rectangular slot in the hollow tube 14 and is fitted with a U-shaped plate 4221. An adjusting component 43 is mounted on the U-shaped plate 4221. The rectangular rod 422 slides in the rectangular slot in the hollow tube 14. The servo motor 423, which drives the screw 421 to rotate, is embedded in the inner wall of the mounting tube 41 and is electrically connected to the controller 2a via a cable.

[0051] The adjusting component 43 includes a vertical push plate 431 and an electric push rod 432. The vertical push plate 431 is slidably mounted on a U-shaped plate 4221. The electric push rod 432 is embedded in the outer side wall of the top of the rectangular rod 422, and the telescopic end of the electric push rod 432 is fixedly connected to the vertical push plate 431. A horizontal plate 4311 is installed at the bottom of the vertical push plate 431. An electric telescopic rod 433 is fixedly installed on the horizontal plate 4311. A U-shaped clamp 434 is fixedly installed at the top of the electric telescopic rod 433. The U-shaped clamp 434 is engaged with the base plate 331, and the distance between the U-shaped clamp 434 and the top of the vertical push plate 431 is adapted to the distance between the base plate 331 and the limiting component 34. Both the electric push rod 432 and the electric telescopic rod 433 are electrically connected to the controller 2a.

[0052] It should be noted that when the lifting component 42 is in use, when the grid component 3 rotates to align with the corresponding lifting component 42, the controller 2a controls the corresponding servo motor 423 to start, driving the screw 421 to rotate. When the screw 421 rotates, the rectangular rod 422 has a threaded hole that is threaded to the screw 421. Under the constraint of the rectangular groove opened in the hollow tube 14, the rectangular rod 422 is driven to slide upward along the screw 421, thereby pushing the U-shaped plate 4221 to move upward synchronously until the vertical push plate 431 is flush with the vertical plate 341. At the same time, the U-shaped clamp 434 on the electric telescopic rod 433 is flush with the bottom plate 331. Then, the electric push rod 432 is controlled to drive the vertical push plate 431 to push the vertical plate 341 to drive the limit rod 343 to exit from the limit hole 303. Then, the electric telescopic rod 433 is controlled to extend and retract, and the U-shaped clamp 434 pulls it. The extension length of multiple plow claws 33 is adjusted by moving the base plate 331. After adjustment, the limiting hole 303 is aligned with the insertion hole 302. Then, the electric push rod 432 is controlled to retract. When retracting, the vertical push plate 431 releases the restriction on the vertical plate 341. The U-shaped clamp 434 exits from the base plate 331 simultaneously, and the vertical plate 341 automatically resets, completing the limit. Then, the servo motor 423 is controlled to reverse, and the rectangular rod 422 is controlled to move down and reset. After adjustment, the grid member 3 automatically moves away from the position of the adjustment mechanism 4. The next grid member 3 entering the adjustment mechanism 4 is adjusted through the same steps as the next group, so that all grid members 3 on the decontamination machine are adjusted in sequence. During this adjustment process, the lifting part 42 and the adjusting part 43 of the adjustment mechanism 4 rotate synchronously with the corresponding grid member 3, so that adjustment can be carried out one by one without stopping the machine.

[0053] Example 2:

[0054] This second embodiment is based on the first embodiment; please refer to... Figures 1 to 13 A collection mechanism 5 is installed on the support frame 1 behind the transmission chain 12. The collection mechanism 5 includes an L-shaped collection box 51. The L-shaped collection box 51 is installed on the support frame 1 and is located at the lower rear drain port of the transmission chain 12. A pusher 52 is installed at the bottom end of the L-shaped collection box 51 that extends into the lower part of the transmission chain 12. A top 53 is installed at the bottom of the L-shaped collection box 51 behind the pusher 52. A puller 54 is installed at the top of the L-shaped collection box 51. A discharge channel 502 is opened at the top of the L-shaped collection box 51 behind the puller 54. A T-shaped channel 504 is symmetrically opened at the bottom of the discharge channel 502. A transfer box 55 is movably inserted in the T-shaped channel 504. The pusher 52, the top 53 and the puller 54 are all electrically connected to the controller 2a.

[0055] Among them, the pusher 52 includes an electro-hydraulic push rod 521. Two electro-hydraulic push rods 521 are fixedly installed at the front end of the bottom of the L-shaped collection box 51, and the telescopic ends of the two electro-hydraulic push rods 521 extend into the L-shaped collection box 51 and are fixedly installed together with a pusher plate 522. The two electro-hydraulic push rods 521 are electrically connected to the controller 2a.

[0056] The top material component 53 includes a push plate 531, a drive shaft 534, and a power motor 535. The push plate 531 is slidably installed inside the L-shaped collection box 51, and a channel steel 532 is symmetrically installed on the bottom of the push plate 531. A rack plate 533 is embedded in the groove of the channel steel 532. The L-shaped collection box 51 is provided with a sliding groove 503 that slides with the channel steel 532. The drive shaft 534 is rotatably installed on the bottom of the L-shaped collection box 51, and a drive gear 5341 is symmetrically sleeved on the drive shaft 534. The drive gear 5341 meshes with the corresponding rack plate 533. The power motor 535 is installed on the outer wall of the L-shaped collection box 51 and is electrically connected to the controller 2a through a cable. The output shaft of the power motor 535 is connected to the drive shaft 534 through a pulley drive. Both the push plate 531 and the bottom of the L-shaped collection box 51 are provided with a drain groove 501.

[0057] The material pulling component 54 includes a pulling plate frame 541 and two electro-hydraulic push rods 542. The pulling plate frame 541 is slidably installed on the top of the L-shaped collection box 51 and located in front of the discharge channel 502. The two electro-hydraulic push rods 542 are symmetrically installed on the outer side wall of the top of the L-shaped collection box 51 and are electrically connected to the controller 2a through cables. The telescopic ends of the two electro-hydraulic push rods 542 are fixedly connected to the pulling plate frame 541.

[0058] It should be noted that when the collection mechanism 5 is in use, if the rear visual camera 2b detects excessive accumulation of solid impurities in the L-shaped collection box 51, the electro-hydraulic push rod 521 is activated first, driving the pusher plate 522 to push the impurities in the L-shaped collection box 51 onto the lower plate 531. During the pushing process, the impurities are simultaneously squeezed to expel moisture from the solid impurities. Then, the power motor 535 is activated, driving the drive shaft 534 to rotate. When the drive shaft 534 rotates, the drive gear 5341 meshes with the rack plate 533, thereby driving the rack plate 533 to drive the channel steel 532 to push the lower pusher plate 531 upward. The top of the moving solid impurities first contacts the bottom of the pull plate frame 541 for further extrusion. Solid impurities are drained by pressing them down. Then, the power motor 535 is reversed, causing the lower push plate 531 to move down a certain distance. Then, the electro-hydraulic actuator 542 is controlled to drive the pull plate frame 541 away from the discharge channel 502. Then, the power motor 535 is started, driving the top of the upper push plate 531 to be flush with the bottom of the pull plate frame 541, so that the solid impurities are flush with the discharge channel 502. Then, the electro-hydraulic actuator 542 is controlled to retract, pulling the solid impurities on the lower push plate 531 into the transfer box 55. The transfer box 55 is movably inserted into the T-slot 504 by two T-blocks 551. After loading, it can be lifted and transferred using the lifting lugs 552 around it, making the transfer of the decontaminated solids very convenient.

[0059] Furthermore, an extension plate 536 is movably inserted into one end of the push plate 531 facing the push plate 522. A limiting spring 5361 is provided between the extension plate 536 and the push plate 531. In this way, when the push plate 522 pushes the solid impurities collected in the L-shaped collection box 51 onto the push plate 531, it simultaneously pushes the extension plate 536 into the push plate 531. Then, after the push plate 522 is released and reset, under the restriction of the limiting spring 5361, the extension plate 536 automatically extends to expand the support area of ​​the push plate 531 and prevent solid impurities from falling off the push plate 531, resulting in incomplete discharge.

[0060] The working principle of the adaptive energy-saving rotary bar screen provided by this invention is as follows:

[0061] When in use, when the support frame 1 is installed on the intercepting water area, the visual camera 2b captures and identifies the solid floating impurities in the water at the front end of the cleaning machine, as well as the solid impurities dredged by the grid piece 3 that has just emerged from the water area. Based on the identified quantity, the information is fed back to the controller 2a. The controller 2a adjusts the speed of the drive motor 22 of the drive mechanism 2 according to the feedback information, thereby adjusting the overall operating speed of the cleaning machine to avoid idling or blockage caused by excessively slow speed, making the cleaning machine more efficient and energy-saving.

[0062] Furthermore, based on the identification of solid impurities in the water body through the shooting, when several grid pieces 3 pass through the adjustment mechanism 4, the lifting piece 42 first releases the restriction of the limiting piece 34 on the multiple plow claws 33 by the adjusting piece 43, and then the adjusting piece 43 cooperates with the base plate 331 to adjust the extension length of the plow claws 33, thereby adjusting the salvage load of a single rotation of the cleaning machine, so as to reduce the salvage load at high speed to avoid the transmission chain 12 from breaking, and maximize the single salvage load at low speed, making the entire cleaning machine more efficient and energy-saving.

[0063] Simultaneously, a collection mechanism 5 is set up. When the rear visual camera 2b captures an excessive accumulation of solid impurities in the L-shaped collection box 51, the electro-hydraulic push rod 521 is activated first, driving the pusher plate 522 to push the impurities in the L-shaped collection box 51 onto the lower plate 531. During the pushing process, simultaneous compression is performed to squeeze out the moisture from the solid impurities. Then, the power motor 535 is activated, driving the drive shaft 534 to rotate. When the drive shaft 534 rotates, the drive gear 5341 meshes with the rack plate 533, thereby driving the rack plate 533 to drive the channel steel 532 to push the lower pusher plate 531 upward. The top of the moving solid impurities first contacts the bottom of the pull plate frame 541, further... The solid impurities are squeezed to drain the water. Then, the power motor 535 is reversed, causing the lower push plate 531 to move down a certain distance. Then, the electro-hydraulic push rod 542 is controlled to drive the pull plate frame 541 away from the discharge channel 502. Then, the power motor 535 is started, driving the top of the upper push plate 531 to be flush with the bottom of the pull plate frame 541, so that the solid impurities are flush with the discharge channel 502. Then, the electro-hydraulic push rod 542 is controlled to retract, pulling the solid impurities on the lower push plate 531 into the transfer box 55. The transfer box 55 is movably inserted into the T-slot 504 by two T-blocks 551. After loading, it can be lifted and transferred using the lifting lugs 552 around it, making the transfer of the decontaminated solids very convenient.
