Description

Technical Field

[0001] This utility model relates to the field of bubble cleaning machine technology, and in particular to a layered filtration device for bubble cleaning machines. Background Technology

[0002] A bubble cleaner is a device that uses bubbles to clean fruits and vegetables. Its principle is based on the energy generated when bubbles burst upon contact with an object, impacting and scrubbing the surface to clean it. However, in existing technologies, the water from bubble cleaners is usually discharged directly, wasting water resources. While some technologies use simple filters installed at the drain pipe to remove impurities, this single-filter method has low efficiency and unsatisfactory results. Furthermore, cleaning the filtered impurities requires personnel to stop the drainage, resulting in low cleaning efficiency. Therefore, this application proposes a layered filtration device for bubble cleaners. Utility Model Content

[0032] There are two sealing plates 2, and two cylindrical tubes 1 are fixedly connected between the two sealing plates 2 on their sides that are close to each other;

[0033] The centrifugal stratification filtration mechanism 4 consists of two sets, which are respectively installed in the corresponding circular cylinders 1.

[0034] The switchable water supply mechanism 3 is embedded and fixed on the top of the sealing plate 2 above. Both centrifugal stratified filtration mechanisms 4 are rotatably sleeved on the switchable water supply mechanism 3. The switchable water supply mechanism 3 is used to switch the drainage position.

[0035] There are two L-shaped drain pipes 5, which are respectively embedded and fixed on both sides of the bottom of the lower sealing plate 2 and connected to the interior of the corresponding circular cylinder 1.

[0036] There are two first solenoid valves 6, which are respectively connected to and fixed at the ends of two L-shaped drain pipes 5 that are far apart from each other.

The L-shaped drain pipes 5 are used to drain the water inside the corresponding cylindrical cylinder 1.

[0037] The centrifugal stratified filtration mechanism 4 includes two cylindrical filter screens 404 with openings at the top. A baffle 405 is fixedly connected to the top of each cylindrical filter screen 404. The two cylindrical filter screens 404 are stacked vertically, with the filter holes of the upper cylindrical filter screen 404 being larger than those of the lower cylindrical filter screen 404. A water collection cover 401, fixedly installed inside a cylindrical cylinder 1, is provided between the two opposing cylindrical filter screens 404. The lower baffle 405 is rotatably and sealingly fitted onto the corresponding water collection cover 404. At the bottom outer side of the 1, the top of the lower baffle 405 has a first bearing hole, and a first sealing bearing is fixedly fitted inside the first bearing hole. The inner side of the inner ring of the first sealing bearing is fixedly connected to the outer side of the corresponding water collection cover 401. The first sealing bearing serves to provide a sealed rotational installation between the lower baffle 405 and the water collection cover 401. The water collection cover 401 is used to collect the water filtered by the upper circular box-shaped filter screen 404 and guide it into the lower circular box-shaped filter screen 404. An L-shaped connecting rod 402 is fixedly connected to the bottom center of the mesh 404. A support rod 408 is fixedly connected between the front inner wall and the rear inner wall of the round box-shaped filter 404. The bottom of the L-shaped connecting rod 402 extends into the corresponding lower round box-shaped filter 404 and is fixedly connected to the right side of the support rod 408. Two drive motors 403 are fixedly installed at the bottom of the lower sealing plate 2 by external bolts (not shown in the figure). The top of the output shaft of the drive motor 403 extends into the corresponding round cylinder 1 and is fixedly connected to the bottom of the lower round box-shaped filter 404. The drive motor 403 is used to drive the centrifugal rotation of the corresponding two round box-shaped filters 404. Two second bearing holes are opened at the bottom of the lower sealing plate 2. A second sealing bearing is fixedly sleeved in the second bearing hole. The inner side of the inner ring of the second sealing bearing is fixedly connected to the outer side of the output shaft of the corresponding drive motor 403.

[0038] The switchable water supply mechanism 3 includes a first connecting pipe 301, wherein a connecting plate is fixedly connected to the left end of the first connecting pipe 301, and the connecting plate connects to the drain pipe on the bubble cleaning machine. The specific connection structure and principle are existing technologies and will not be described in detail here. A second solenoid valve 303 is fixedly connected to the right end and the top of the first connecting pipe 301. A first connecting pipe 304 and a second connecting pipe 302 are fixedly connected to the right side of the second solenoid valve 303 and the top of the second solenoid valve 303, respectively. The bottom ends of the first connecting pipe 304 and the bottom ends of the second connecting pipe 302 extend to... Inside the corresponding cylindrical tube 1, the upper sealing plate 2 is fixedly fitted on the outside of the first connecting pipe 304 and the second connecting pipe 302. The two baffles 405 located above are respectively sealed and rotatably fitted on the first connecting pipe 304 and the second connecting pipe 302. The top of each of the two upper baffles 405 is provided with a third bearing hole. A third sealing bearing is fixedly fitted in the third bearing hole. The inner side of the inner ring of the two third sealing bearings is fixedly connected to the outer side of the first connecting pipe 304 and the second connecting pipe 302 respectively. The third sealing bearings serve to allow the first connecting pipe 304 and the second connecting pipe 302 to be rotatably installed.

[0039] In this implementation scheme: the first connecting pipe 301 is connected to the drain pipe of the bubble cleaner. First, the second solenoid valve 303 on the right, the first solenoid valve 6 on the left, and the drive motor 403 on the left are opened. The output shaft of the drive motor 403 drives the lower circular filter screen 404 to rotate. The lower circular filter screen 404, through the corresponding support rod 408 and L-shaped connecting rod 402, drives the upper circular filter screen 404 to rotate. The water discharged from the drain pipe of the bubble cleaner enters the upper circular filter screen 404 through the first connecting pipe 301, the second solenoid valve 303 on the right, and the first connecting pipe 304. The upper circular filter screen 404... The incoming water undergoes initial filtration. As the upper circular filter screen 404 rotates, it centrifugally ejects the water, trapping particulate impurities within it. The ejected water then flows through the corresponding water collection hood 401 into the lower circular filter screen 404. As the lower circular filter screen 404 rotates, it ejects its internal water, trapping impurities within it. The lower circular filter screen 404 then performs secondary filtration on the incoming water. The ejected water is then discharged to the outside via the corresponding L-shaped drain pipe 5 and the first solenoid valve 6. Through this secondary stratified filtration, impurities in the water can be effectively filtered out, thereby improving filtration efficiency.

[0040] Furthermore:

[0041] The layered filtration device for the bubble cleaning machine also includes a control and reminder mechanism 7, which is installed on the bottom of the lower sealing plate 2 and on two drive motors 403;

[0042] The control and reminder mechanism 7 includes a PLC timer controller 701 and two audible and visual alarm lights 702. Both audible and visual alarm lights 702 are electrically connected to the PLC timer controller 701. The two audible and visual alarm lights 702 are respectively fixedly connected to the front side of the corresponding drive motor 403. The second solenoid valve 303, the drive motor 403 and the first solenoid valve 6 are all electrically connected to the PLC timer controller 701. The PLC timer controller 701 is used to set the opening and closing time of the first solenoid valve 6, the second solenoid valve 303 and the drive motor 403. The audible and visual alarm lights 702 are used to remind personnel with audible and visual alarms. The PLC timer controller 701 is installed at the bottom of the sealing plate 2 below.

[0043] The slag removal mechanism consists of four sets. Each mechanism includes a circular slag collection plate 406, which makes movable contact with the bottom inner wall of a corresponding circular box-shaped filter screen 404. The dimensions of the circular slag collection plate 406 are the same as the dimensions of the bottom inner wall of the circular box-shaped filter screen 404. Filtered impurities are blocked at the top of the circular slag collection plate 406. Each of the two opposing circular box-shaped filter screens 404 has a first through hole with an open top on its far side. A semi-circular filter screen 407 is movably fitted inside the first through hole. The bottom of the opposite semi-circular filter screens 407 on their closest sides respectively makes contact with the bottom of the opposite semi-circular filter screen 404. A corresponding circular slag collection plate 406 is fixedly connected, wherein the maximum diameter of the semi-circular filter screen 407 is the same as the maximum diameter of the circular slag collection plate 406, so that the circular slag collection plate 406 can be moved to the outside through the corresponding first through hole. The two opposing support rods 408 are provided with threaded grooves on their opposite sides, and T-shaped fixing bolts 409 are threadedly fitted into the threaded grooves. An internal threaded sleeve 410 is embedded and fixed on one side of the semi-circular filter screen 407, and the internal threaded sleeve 410 is threaded onto the corresponding T-shaped fixing bolt 409. The semi-circular filter screen 407 is achieved through the internal threaded sleeve 410. The filter screen 407 is threadedly connected to the corresponding T-shaped fixing bolt 409. The T-shaped fixing bolt 409 can fix the semi-circular filter screen 407. Two loading and unloading holes are opened on the opposite sides of the two circular cylinders 1. The loading and unloading holes correspond to the corresponding semi-circular filter screens 407. The inner diameter of the loading and unloading holes matches the outer diameter of the semi-circular filter screens 407, so that the semi-circular filter screens 407 can be moved out of the corresponding loading and unloading holes. A T-shaped plug 411 is movably fitted in the loading and unloading holes. The T-shaped plug 411 is magnetically fixed to the corresponding circular cylinder 1. Four grooves are provided on the opposite sides of each cylinder 1. A first magnet is fixedly connected to the inner wall of the groove on the side away from its opening. A second magnet is fixedly connected to the inner wall of the T-shaped block 411 on the side away from the corresponding circular cylinder 1. The second magnet is movably fitted in the corresponding groove and attracts the first magnet. The T-shaped block 11 and the corresponding circular cylinder 1 are fixedly connected by the first magnet and the second magnet. The T-shaped block 411 is used to block the corresponding take-up and put-out holes. Pull rings are fixedly connected to the opposite sides of the two T-shaped blocks 411 on the opposite sides.

[0044] In this implementation scheme: the interval time between the two drive motors 403, the interval time between the two first solenoid valves 6, and the interval time between the two second solenoid valves 303 are preset by the PLC timer controller 701. When the cleaning time is reached, the PLC timer controller 701 controls the left drive motor 403, the left first solenoid valve 6, and the right second solenoid valve 303 to close, and controls the right drive motor 403, the right first solenoid valve 6, the upper second solenoid valve 303 to open, and the left audible and visual alarm light 702 to turn on. The left audible and visual alarm light 702 turns on to remind personnel to clean, so that the two round box-shaped filter screens 404 on the right continue to perform layered centrifugal filtration by centrifugal rotation. While the two round box-shaped filter screens 404 on the right are filtering, personnel can clean the impurities inside the two round box-shaped filter screens 404 on the left. During cleaning, pulling the pull ring moves the corresponding T-shaped sealing block 411 out of the pick-and-place hole, and then the corresponding T-shaped fixing bolt 409 is rotated in the opposite direction to separate from the thread groove, releasing the half After fixing the circular filter screen 407, the semi-circular filter screen 407 can be moved to the left, causing the corresponding circular slag collection plate 406 and the impurities on it to be removed from the circular box-shaped filter screen 404 and the pick-and-place hole. This allows the impurities on the circular slag collection plate 406 to be cleaned. After cleaning, the circular slag collection plate 406 can be reinstalled into the corresponding circular box-shaped filter screen 404. Then, the T-shaped block 411 is fixed back into the corresponding pick-and-place hole, ready for the next cleaning operation. When the next cleaning time is reached, the PLC timer controller 70... 1. Control the second solenoid valve 303 on the right to open again, the first solenoid valve 6 on the left, the drive motor 403 on the left and the audible and visual alarm light 702 on the right to open, and control the second solenoid valve 303 on the top, the first solenoid valve 6 on the right, the drive motor 403 on the right and the audible and visual alarm light 702 on the left to close. This will switch to centrifugal filtration through the two round box-shaped filters 404 on the left, which will clean the impurities inside the two round box-shaped filters 404 on the right, thereby achieving the purpose of alternating filtration and cleaning without stopping the machine.

[0045] It should be noted that the first solenoid valve 6, the drive motor 403, the second solenoid valve 303, and the audible and visual alarm light 702 are all electrically connected to the PLC timer controller 701 via wires.

[0046] The audible and visual alarm light 702 can preferably be a Schneider XAL-A series audible and visual alarm light. The PLC timer controller 701 can preferably be a Siemens SIMATIC S7-1200. The first solenoid valve 6 and the second solenoid valve 303 can preferably be an Airtac 4V210-08. When the PLC timer controller 701 outputs a low level, it can control the first solenoid valve 6 and the second solenoid valve 303 to de-energize, reset the valve core, and close the corresponding air circuit. When the PLC timer controller 701 outputs a high level, the coils of the first solenoid valve 6 and the second solenoid valve 303 are energized, opening the corresponding air circuit. The drive motor 403 is a combination motor of Siemens 1LE0 series motor + SINAMICS V20 frequency converter. When controlling the drive motor 403, the PLC timer controller 701 outputs a relay signal (DO point) to switch the motor power supply on and off to achieve simple start and stop. The specific control principle is existing technology and will not be elaborated here.

[0047] Working principle: The first connecting pipe 301 is connected to the drain pipe of the bubble cleaner. The interval time between the two drive motors 403, the interval time between the two first solenoid valves 6, and the interval time between the two second solenoid valves 303 are preset by the PLC timer controller 701. First, the second solenoid valve 303 on the right, the first solenoid valve 6 on the left, and the drive motor 403 on the left are opened. The output shaft of the drive motor 403 drives the lower circular box-shaped filter screen 404 to rotate. The lower circular box-shaped filter screen 404 drives the upper circular box-shaped filter screen 404 to rotate through the corresponding support rod 408 and L-shaped connecting rod 402. The water discharged from the drain pipe of the bubble cleaner enters the upper circular box-shaped filter screen 404 through the first connecting pipe 301, the second solenoid valve 303 on the right, and the first connecting pipe 304. Inside 04, the upper circular box-shaped filter 404 performs initial filtration of the incoming water. As the upper circular box-shaped filter 404 rotates, it centrifugally throws the water out, and particulate impurities are trapped inside the upper circular box-shaped filter 404. The thrown-out water enters the lower circular box-shaped filter 404 through the corresponding water collection hood 401. As the lower circular box-shaped filter 404 rotates, it throws out the water inside, and its impurities are trapped inside the lower circular box-shaped filter 404. The thrown-out water is discharged to the outside through the corresponding L-shaped drain pipe 5 and the first solenoid valve 6. The lower circular box-shaped filter 404 performs secondary filtration of the incoming water. Through secondary filtration, impurities in the water can be effectively filtered out. The filtered water is discharged to the outside through the corresponding L-shaped drain pipe 5 and the first solenoid valve 6. The centrifugal filtration method improves the filtration efficiency.

[0048] While the circular box-shaped filter screen 404 is filtering, the filtered impurities are blocked on the top of the circular slag collection plate 406. When the cleaning time is reached, the PLC timer controller 701 controls the left drive motor 403, the left first solenoid valve 6, and the right second solenoid valve 303 to close, and controls the right drive motor 403, the right first solenoid valve 6, the upper second solenoid valve 303 to open, and the left audible and visual alarm light 702 to turn on. The left audible and visual alarm light 702 turns on to remind personnel to clean, causing the two circular box-shaped filter screens 404 on the right to rotate centrifugally, so that the discharged water passes through the upper second solenoid valve 303, the second... The filter is discharged to the outside via the connecting pipe 302, the upper right circular box-shaped filter screen 404, the right water collection cover 401, the lower right circular box-shaped filter screen 404, the right L-shaped drain pipe 5, and the right first solenoid valve 6. While the two circular box-shaped filters 404 on the right are filtering, personnel can clean the impurities inside the two circular box-shaped filters 404 on the left. During cleaning, pulling the pull ring moves the corresponding T-shaped sealing block 411 out of the pick-and-place hole. Then, the corresponding T-shaped fixing bolt 409 is rotated in the opposite direction to separate from the threaded groove, releasing the fixation of the semi-circular filter screen 407. Then, the semi-circular filter screen 407 can be moved to the left to move the filter screen 407. The corresponding circular slag collection plate 406 is removed from the circular box-shaped filter screen 404. The circular slag collection plate 406 carries the impurities on it out of the circular box-shaped filter screen 404 and out through the pick-and-place hole to the outside, thus cleaning the impurities on the circular slag collection plate 406. After cleaning, the circular slag collection plate 406 can be moved back into the corresponding circular box-shaped filter screen 404, and the semi-circular filter screen 407 can be fixed by rotating the T-shaped fixing bolt 409 in the threaded groove. Then, the T-shaped block 411 is fixed again in the corresponding pick-and-place hole, ready for the next cleaning operation. When the next cleaning time is reached, the PLC timer controller... 701 again controls the second solenoid valve 303 on the right to open, the first solenoid valve 6 on the left, the drive motor 403 on the left, and the audible and visual alarm light 702 on the right to open, and controls the second solenoid valve 303 on the top, the first solenoid valve 6 on the right, the drive motor 403 on the right, and the audible and visual alarm light 702 on the left to close. This switches to centrifugal filtration through the two round box-shaped filters 404 on the left, which cleans the impurities inside the two round box-shaped filters 404 on the right. This achieves the purpose of alternating filtration and cleaning without stopping the machine. Furthermore, by alternating cleaning without stopping the machine, the downtime waiting time can be effectively reduced, thereby improving the cleaning efficiency.

[0049] Example 2

[0050] Reference Figure 4This embodiment differs from Embodiment 1 in that: two L-shaped support plates are fixedly connected to the bottom of the lower sealing plate 2, and the drive motor 403 is fixedly connected to the inner wall of the bottom of the corresponding L-shaped support plate by external bolts (not shown in the figure). The L-shaped support plate is used to support the corresponding drive motor 403. A pointer 8 is fixedly connected to the outside of the output shaft of the drive motor 403. The two pointers 8 are symmetrically arranged and are used to indicate the rotation position of the circular filter screen 404.

[0051] The usage method of this embodiment is as follows: Unlike Embodiment 1, it also has the following functions: While the output shaft of the drive motor 403 rotates, it also drives the corresponding pointer 8 to rotate. When the pointer 8 rotates to a position away from the PLC timer controller 701, it indicates that the semi-circular filter screen 407 is aligned with the corresponding pick-up / placement hole, making it convenient for personnel to directly remove the semi-circular filter screen 407. If the pointer 8 rotates to other positions, it indicates that the semi-circular filter screen 407 is not aligned with the corresponding pick-up / placement hole. When removing slag, personnel can turn on the drive motor 403 so that the circular filter screen 404 drives the corresponding semi-circular filter screen 407 to align with the pick-up / placement hole. Then, the drive motor 403 can be turned off, and the slag removal operation can be performed directly.
