Description

Technical Field

[0001] The invention relates to a filtering mechanism, in particular to a circulating filtering mechanism for a cleaning machine, belonging to the technical field of cleaning machines. Background Art

[0002] A cleaning machine is a device used to clean dirt, impurities, etc. on the surface of various objects. It has a wide range of applications. According to the cleaning method, it can be divided into ultrasonic cleaning machines, high-pressure cleaning machines, spray cleaning machines and brush cleaning machines. In order to save water used for cleaning, the cleaning machine can be equipped with a circulating filtering mechanism during use.

[0003] In the prior art, for example, a utility model with application number 202322184584.X discloses a liquid filtering mechanism for an ultrasonic cleaning machine. In order to solve the problem that the cleaning solvent containing impurities is directly discharged, such direct discharge will increase the cleaning cost of the ultrasonic cleaning machine, and impurities are easily accumulated and block the discharge pipe. By placing the discharge pipe for discharging sewage at a higher position, the impeller will be driven to rotate when the water falls, thereby driving the rotation of the fixed shaft and then cleaning the filter screen through a cleaning brush. Due to the presence of a reciprocating screw, the cleaning brush will repeatedly clean the mesh body. At the same time, since it is driven by the water body, it is ensured that the mesh body will be cleaned all the time when the water body is discharged to prevent the mesh holes of the mesh body from being blocked.

[0004] Similar to the above application, there are still some shortcomings:

[0005] During filtering, impurities cannot be graded and collected. The filtering load of a single filter is large, which affects the filtering cycle effect. Although the filter can be cleaned with a cleaning brush, the impurities cannot be discharged after cleaning. The impurities are always located inside the filter bin and will quickly cause the filter to become clogged.

[0006] For this reason, a circulating filtering mechanism for a cleaning machine is designed to optimize the above-mentioned problems. Summary of the invention

[0007] The main purpose of the present invention is to provide a circulating filter mechanism for a cleaning machine, which is provided with an impurity collecting bin, a sedimentation bin and a filter bin inside the circulating filter box, and a large impurity filter mechanism obliquely arranged between the impurity collecting bin and the water inlet, so as to pre-treat large impurities, and then use the large mass particle collection mechanism on the top of the sedimentation bin to collect and store impurity particles with a large specific gravity, so as to recycle metal particles, and finally use the cleaning mechanism inside the filter bin to clean the fine filter screen and discharge the scraped impurities, which not only improves the functionality of the device, but also adopts a graded treatment method to improve the filtering cycle effect and reduce the use load of the filter screen. The large impurity filter mechanism composed of a roller, a coarse filter screen, a baffle, a rotating rod, a cleaning brush, a driven gear and a driving gear can control the rotation of the coarse filter screen by the impact force of the cleaning water flowing in during use. At the same time, the large particle impurities are directly transported to the impurity collection bin for storage, which makes filtering and collection more convenient. The large-mass particle collection mechanism is composed of a guide plate, a slide, an upper guide groove, a lower guide groove, a baffle, a partition, a storage groove, a reset spring, a receiving bucket, a shaft rod, a blade plate, a cam, a lever, and a strip groove. When the large-density particles flow downward together with the water flow, the baffle bar can intercept the particles and retain them in the storage groove. The impact force of the water flow is then used to drive the shaft rod to rotate, and the sliding of the baffle is reciprocated to automatically transfer the particles in the storage groove to the receiving bucket for storage. The collection and storage is more convenient. Through the horizontal plate, rotating groove, roller, rubber The cleaning mechanism, which is composed of a rubber scraper, a temporary storage tank, a transfer bin, a material drop port, a discharge pipe, a mounting groove, a clockwork spring, a reciprocating screw, a slider, a worm gear, and a worm, also uses the impact force of the water flow as a power source to reciprocately control the rubber scraper to clean the surface of the fine filter, and in the process of moving upward for cleaning, the adhered impurities are automatically transported to the inside of the temporary storage tank, and in the process of moving downward for cleaning, the impurities are transferred to the inside of the transfer bin, and finally discharged from the discharge pipe to the inside of the circulation filter box, thereby increasing the service life of the fine filter.

[0044] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0045] like Figure 1-Figure 8As shown, this embodiment provides a circulating filtering mechanism for a cleaning machine, comprising a circulating filtering box 1, a water inlet 2 opened on one side of the top of the circulating filtering box 1, and a circulating water pump 11 installed on the side of the circulating filtering box 1, an impurity collecting bin 3 is provided on the side of the top of the circulating filtering box 1 away from the water inlet 2, a large impurity filtering mechanism 4 is obliquely arranged between the bottom of the water inlet 2 and the top of the impurity collecting bin 3, a sedimentation bin 5 is provided below the side of the circulating filtering box 1 close to the water inlet 2, a large mass particle collecting mechanism 6 is provided at the top of the sedimentation bin 5 and below the large impurity filtering mechanism 4, a filter bin 7 is provided on the side of the circulating filtering box 1 away from the sedimentation bin 5, the input end of the circulating water pump 11 is connected to the inside of the filter bin 7, a fine filter screen 8 is vertically arranged inside the circulating water pump 11, a cleaning mechanism 9 is provided on the side of the fine filter screen 8 close to the sedimentation bin 5, and an overflow port 10 is provided between the side of the sedimentation bin 5 and the filter bin 7.

[0046] The overall working principle is: use a high-pressure water pump to extract the cleaning waste water inside the cleaning machine, and inject the cleaning waste water into the circulation filter box 1 from the water inlet 2. The waste water is first filtered by the large impurity filtering mechanism 4, and the impurities after filtering are stored in the impurity collection bin 3. The filtered waste water will flow into the top of the large-mass particle collecting mechanism 6 and flow downward along the large-mass particle collecting mechanism 6. Since the large-mass particles have a faster sedimentation rate, they will be intercepted and collected by the large-mass particle collecting mechanism 6. If the particles The particulate matter contains metal particles, which can be recycled. After the large mass particles are collected, the wastewater falls into the sedimentation bin 5, and the sludge in the wastewater is precipitated. The supernatant after precipitation enters the filter bin 7 from the overflow port 10, and after being filtered by the fine filter 8, it can be returned to the inside of the cleaning machine by the circulating water pump 11. After the wastewater passes through the fine filter 8 for filtration, the cleaning mechanism 9 is used to clean and discharge the impurities on the surface of the fine filter 8 to prevent the impurities from sticking to the fine filter 8 again, thereby increasing the service life of the fine filter 8.

[0047] In this embodiment, a vertical plate 12 is installed between the two ends inside the sedimentation bin 5, and there is a gap between the bottom of the vertical plate 12 and the inner bottom of the sedimentation bin 5. There are two groups of vertical plates 12, and the two groups of vertical plates 12 are parallel to each other.

[0048] Local working principle: After the wastewater falls into the sedimentation bin 5, the vertical plate 12 can play a certain barrier role on the wastewater, reducing the interference effect of the wastewater on the original wastewater in the sedimentation bin 5 when it falls, so as to facilitate the sedimentation of the wastewater. When there is a lot of sediment in the sedimentation bin 5, the slurry pump can be connected to discharge the sediment.

[0049] In this embodiment, the large impurity filtering mechanism 4 includes a roller 401, a coarse filter screen 402, a baffle 403 and a cleaning component. The roller 401 is rotatably installed between the two ends of the circulation filter box 1, and two groups of rollers 401 are provided. A coarse filter screen 402 is provided between the two groups of rollers 401. The coarse filter screen 402 is inclined toward the inside of the impurity collecting bin 3. The baffle 403 is evenly and vertically fixed on the outside of the coarse filter screen 402. The inside of the impurity collecting bin 3 is provided with a cleaning component for cleaning the surface of the coarse filter screen 402.

[0050] Local working principle: After the wastewater is injected into the water inlet 2 at a high speed, it will not only pass through the coarse filter 402, but also impact on the baffle 403, thereby driving the coarse filter 402 to rotate toward the impurity collection bin 3, and the impurities will fall into the interior of the impurity collection bin 3. If there are impurities stuck on the coarse filter 402, the cleaning component can be used to clean the impurities on the coarse filter 402.

[0051] In this embodiment, the cleaning assembly includes a rotating rod 404, cleaning bristles 405, a driven gear 406 and a driving gear 407. The rotating rod 404 is rotatably installed between the two ends of the impurity collection bin 3. Cleaning bristles 405 are provided on the outer side of the rotating rod 404. The cleaning bristles 405 are in contact with the surface of the coarse filter 402. A driven gear 406 is provided at the end of the rotating rod 404, and a driving gear 407 meshing with the driven gear 406 is fixed to one end of the roller 401.

[0052] Local working principle: When the coarse filter 402 rotates, it will also drive the roller 401 to rotate. The rotation of the roller 401 will drive the driving gear 407 and the driven gear 406 to rotate, thereby controlling the rotation of the rotating rod 404 and the cleaning brush 405 to clean the surface of the coarse filter 402 and ensure that large impurities completely fall into the impurity collection bin 3.

[0053] In this embodiment, the cleaning mechanism 9 includes a transverse plate 901, a rotating groove 902, a roller 903, a rubber scraper 904, a mounting groove 909, a spring spring 910, a discharge assembly and a lifting assembly. The transverse plate 901 is arranged along the width direction of the fine filter 8. A rotating groove 902 is provided on one side of the transverse plate 901 close to the fine filter 8. A roller 903 is rotatably installed inside the rotating groove 902. A rubber scraper 904 that fits the surface of the fine filter 8 is fixed in the side extension direction of the roller 903. Mounting grooves 909 are provided at both ends of the rotating groove 902. Spring springs 910 are installed inside the mounting grooves 909. The outer end of the spring spring 910 is fixedly connected to the inner wall of the mounting groove 909, and the inner end of the spring spring 910 is fixedly connected to the end of the roller 903. A discharge assembly is provided below the transverse plate 901, and a lifting assembly for controlling the up and down movement of the transverse plate 901 is provided inside the filter bin 7.

[0054] Local working principle: when the fine filter 8 filters wastewater, certain impurities will adhere to the surface. In order to ensure the normal filtration of the fine filter 8, the lifting assembly is used to drive the horizontal plate 901 to move up and down, and the rubber scraper 904 on the horizontal plate 901 fits with the surface of the fine filter 8. When the horizontal plate 901 moves upward, the rubber scraper 904 fits on the surface of the fine filter 8 and tilts downward. When the horizontal plate 901 moves downward, the rubber scraper 904 fits on the surface of the fine filter 8 and tilts upward. When the rubber scraper 904 fits with the fine filter 8, it will be subject to the elastic force applied by the clockwork spring 910, thereby ensuring the fit effect of the rubber scraper 904 and the fine filter 8. In the process of the rubber scraper 904 fitting on the fine filter 8 and moving upward, the discharge assembly can be used to store the cleaned impurities, and in the process of the rubber scraper 904 fitting on the fine filter 8 and moving downward, the discharge assembly is used to discharge the impurities to the outside.

[0055] In this embodiment, the discharge component includes a temporary storage tank 905, a transfer bin 906, a material drop port 907 and a discharge pipe 908. The temporary storage tank 905 is opened between the symmetrical sides of the roller 903. The transfer bin 906 is provided below the cross plate 901.

The discharge pipe 908 is installed at the bottom end of the transfer bin 906, and the bottom end of the discharge pipe 908 extends to the outside of the circulation filter box 1.

[0056] Local working principle: When the rubber scraper 904 is attached to the fine filter 8 and moves upward, the impurities scraped off by the rubber scraper 904 will gather on the surface of the rubber scraper 904 and enter the temporary storage tank 905. When the rubber scraper 904 is attached to the fine filter 8 and moves downward, the rubber scraper 904 will tilt upward and drive the roller 903 to rotate, hiding the temporary storage tank 905 inside the rotating tank 902, and entering the transfer bin 906 through the drop port 907, and then discharged to the outside of the circulating filter box 1 through the discharge pipe 908.

[0057] In this embodiment, the lifting assembly includes a reciprocating screw rod 911, a slider 912 and a rotating part. The reciprocating screw rod 911 is vertically rotatably installed inside the filter bin 7. A slider 912 is provided on the reciprocating screw rod 911. The slider 912 is fixed to the side of the cross plate 901. A rotating part is provided on the top of the reciprocating screw rod 911.

[0058] Partial working principle: In the process of controlling the lifting of the horizontal plate 901 , the rotation of the reciprocating screw 911 is controlled by the rotating part, and the slider 912 reciprocates along the length direction of the reciprocating screw 911 , thereby driving the lifting of the horizontal plate 901 .

[0059] In this embodiment, the rotating part includes a worm wheel 913 and a worm 914 . The worm wheel 913 is fixed to the top of the reciprocating screw 911 , and the worm 914 is fixed to the end of the roller 401 . The worm 914 is meshed with the worm wheel 913 .

[0060] Partial working principle: When the wastewater is filtered and circulated, the roller 401 drives the worm 914 to rotate, the rotation of the worm 914 controls the rotation of the worm wheel 913, and the rotation of the worm wheel 913 drives the rotation of the reciprocating screw 911.

[0061] In this embodiment, the large mass particle collection mechanism 6 includes a guide plate 601, a chute 602, an upper guide groove 603, a lower guide groove 604, a baffle 605, a partition 606, a storage groove 607, a return spring 608, a receiving bucket 609 and a gap drive assembly. The guide plate 601 is tilted at the inner top of the sedimentation bin 5, and the bottom end of the guide plate 601 faces the side wall of the circulation filter box 1. The chute 602 is opened at the middle position of the guide plate 601. The top of the guide plate 601 is evenly opened along the length direction with an upper guide groove 603 that is connected to the inside of the chute 602. The bottom of the guide plate 601 is opened along the length direction with a The lower guide groove 604 is connected to the upper guide groove 603, and the upper guide groove 603 is staggered with the lower guide groove 604. The top of the guide plate 601 is evenly provided with baffles 605 along the length direction. The upper guide groove 603 is located between adjacent baffles 605. The guide plate 601 is internally slidably provided with partitions 606. Storage grooves 607 are evenly opened on the partitions 606.

[0062] Partial working principle: after preliminary filtration, the wastewater falls into the top of the guide plate 601 and flows downward. Due to the blocking effect of the baffle 605 on the water flow, the water flow will flow through the top of the baffle 605. The particles with heavier weight fall at a faster rate, are intercepted by the baffle 605 and stored in the storage groove 607 through the upper guide groove 603. In the initial state, the upper guide groove 603 and the storage groove 607 are connected. As the particles with large specific gravity are continuously collected, the gap drive component controls the partition 606 to slide inside the slide groove 602, connecting the storage groove 607 and the lower guide groove 604. The particles collected in the storage groove 607 fall into the receiving bucket 609 through the lower guide groove 604 for storage, and then the partition 606 is reset under the action of the reset spring 608. The partition 606 continues to slide and continues to intercept and collect the particles. When the receiving bucket 609 stores a lot of impurities, the cleaning port on the side of the circulation filter box 1 is opened to discharge the particle impurities.

[0063] In this embodiment, the gap driving mechanism includes a shaft rod 610, a blade plate 611, a cam 612, a lever 613 and a strip groove 614. The shaft rod 610 is rotatably installed between the two ends of the sedimentation bin 5. The shaft rod 610 is located below the bottom end of the guide plate 601. The outer side of the shaft rod 610 is evenly provided with blade plates 611 along the circumferential direction. A cam 612 is fixed at one end of the shaft rod 610. A lever 613 is fixed at the bottom of the partition 606. A strip groove 614 cooperating with the lever 613 is opened at the bottom of the guide plate 601, and the lever 613 slides inside the strip groove 614.

[0064] Local working principle: When wastewater flows down from the guide plate 601, it will impact the surface of the blade 611, exerting thrust on the blade 611, controlling the shaft 610 to rotate in the opposite direction, and the cam 612 on the shaft 610 rotates together. When the cam 612 contacts the lever 613, as the cam 612 continues to rotate, it will squeeze the lever 613, control the guide plate 601 to slide upward, and discharge the particles into storage. When the cam 612 separates from the lever 613, the reset spring 608 will control the automatic reset of the guide plate 601 to continue collecting the particles.
