DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] See also Figures 1 to 9 In the embodiment of the utility model, a novel circulation filtering device comprises a box base 1, a vibration component is fixedly installed on the top of the box base 1, and a first station component and a second station component are symmetrically installed on the vibration component;

[0037] The first station component is used to discharge the concentrated liquid without drug residue; the second station component is used to discharge the drug residue;

[0038] A rectangular cover 7 with a hollow structure is installed above the first station assembly and the second station assembly. Two filter assemblies arranged up and down are slidably connected to the inner cavity of the rectangular cover 7. A transverse slide 8 for sliding the two groups of filter assemblies is provided on the rectangular cover 7. Fixing assemblies for fixing the filter assemblies are provided at diagonal positions at both ends of the inner side of the transverse slide 8.

[0039] The filtering component located above the first station component is used to filter the drug residue in the concentrated liquid, and the filtering component located above the second station component is used to discharge the drug residue.

[0040] In this embodiment: when the staff uses the vibration filtering device to filter the concentrated liquid, the machine is first started, and the vibration motor assembly in the protective cover 3 drives the filter frame 1001 on the first station of the vibration plate 4 to vibrate;

[0041] Afterwards, the staff slowly pours the pulp in the transferred barrel onto the filter frame 1001 on the first station in the rectangular cover 7. The vibrating filter frame 1001 retains the drug residue on the mesh through the filter screen, and the concentrated liquid flows into the first containing cylinder 5 through the holes of the filter screen, and then flows into the prepared barrel through the concentrated liquid outlet port 6;

[0042] As the amount of fruit pulp filtered increases, a large amount of drug residue accumulates on the filter screen of the filter frame 1001 on the first station, affecting the filtering efficiency. At this time, the staff can pinch the handle 20 of the first fixing component and pull it down, and the sliding fixing column 19 moves down along the slide groove 17 in the direction of squeezing the third spring 18, leaving the inner cavity of the fixing hole 1005, so that the filter frame 1001 on the first station can be released from the fixation. At the same time, the rotating handle 1004 is held to make the filter frame 1001 with accumulated drug residue move along the lower horizontal slide groove 8 to the other side. When the filter frame 1001 is about to slide to the annular portion at the other end, the rotating handle 1004 is rotated to make the filter frame 1001 flip 180 degrees, the filter screen is inverted, and then the filter frame 1001 continues to be translated;

[0043] As the first moving end 1002 and the second moving end 1003 slide, they touch the second fixing assembly located on the upper wall of the semicircular portion. The sliding fixing column 19 squeezed by the touch first moves upward and then, driven by the third spring 18, enters the fixing hole 1005 on the inverted filter frame 1001, thereby fixing the filter frame 1001 with a large amount of drug residue accumulated thereon in an inverted manner.

[0044] At this time, pull the handle 20 of the second fixing assembly in the upper row upwards to release the fixation of the inverted clean filter frame 1001 on the second station, then hold the rotating handle 1004 to slide the clean filter frame 1001 along the upper row of transverse chutes 8 to the first station, and rotate the filter frame 1001 to a forward position during the sliding process. As the clean filter frame 1001 slides to the other semicircular portion of the upper row of transverse chutes 8, the first fixing assembly fixes the clean filter frame 1001, and the pulp can be poured in for filtration.

[0045] On the other side, the spray cleaning function is turned on, and the water flow sprayed from the spray head 12 washes the drug residue on the filter screen of the inverted filter frame 1001 into the second containing cylinder, and then the drug residue slides into the prepared barrel along the filter residue outlet end 15;

[0046] In this way, the filter replacement time is greatly shortened and the concentrate filtration efficiency is improved.

[0047] Please refer to Figures 1-2 The first station assembly includes a first containing cylinder 5 disposed at the top of the vibration assembly, and the discharge port of the first containing cylinder 5 is connected to a concentrated liquid outlet end 6;

[0048] The second station assembly comprises a second containing barrel 9 arranged at the top of the vibration assembly, and a filter residue outlet end 15 is arranged at the discharge port of the second containing barrel 9 .

[0049] In this embodiment: when the staff uses the vibration filtering device to filter the concentrated liquid, the vibration motor assembly in the protective cover 3 drives the filter frame 1001 on the first station on the vibration disk 4 to vibrate, and the filtered concentrated liquid first flows into the first containing tube 5, and then flows into the pre-prepared collection bucket through the concentrated liquid outlet end 6. During cleaning, the spray head 12 on the second station cleans the inverted filter frame 1001 below, and the drug residue washed out from the filter net falls into the second containing tube 9, and then flows out through the filter residue outlet end 15.

[0050] Please refer to Figures 1 to 3 The filter assembly includes two filter frames 1001 slidably connected to the inner cavity 7, the two filter frames 1001 are staggered in an up-and-down manner, and the two ends of the two filter frames 1001 are respectively integrally formed with a first movable end 1002 and a second movable end 1003, and the end of the second movable end 1003 away from the filter frame 1001 is integrally formed with a rotating handle 1004;

[0051] The first movable end 1002 and the second movable end 1003 are both slidably connected to the inner cavity of the transverse slide groove 8, and the first movable end 1002 and the second movable end 1003 are both provided with a fixing hole 1005 for docking with the fixing component;

[0052] The first movable end portion 1002 and the second movable end portion 1003 are both cylindrical structures.

[0053] In this embodiment: During the filtering process using the device, the staff flips the filter frame 1001 by holding the rotating handle 1004, and switches the filter frame 1001 between the first station and the second station by sliding the first movable end 1002 and the second movable end 1003 in the inner cavity of the transverse slide groove 8.

[0054] Please refer to Figures 1 to 9 The fixing assembly includes a columnar slide groove 17 which is diagonally opened inside the rectangular cover 7, and the columnar slide groove 17 is connected to the inner side of the transverse slide groove 8;

[0055] The bottom end of the inner wall of the columnar slide 17 is fixedly connected with a third spring 18, the top end of the third spring 18 is fixedly connected with a sliding fixed column 19 slidably connected to the columnar slide 17, the outer wall of the sliding fixed column 19 is integrally formed with a pull handle 20 that penetrates to the outside of the rectangular cover 7, and the outer wall of the sliding fixed column 19 is provided with a fixing column bolt opening 22;

[0056] The outer wall of the rectangular cover 7 is provided with a side wall bolt opening 21 aligned with the fixing column bolt opening 22 in the reset state;

[0057] The outer wall of the rectangular cover 7 is provided with a side wall slide groove 16 for the pull handle 20 to move up and down

[0058] One end of the sliding fixing column 19 away from the third spring 18 is in an inclined surface, and the inclined surface is away from the semicircular portion of the transverse sliding groove 8 .

[0059] In this embodiment: during the filtering process using the device, the fixing assembly above the first station is used to fix the upright filter frame 1001 for filtering, and the fixing assembly above the second station is used to fix the inverted filter frame 1001 for easy cleaning. During the filtering process, fixing bolts are inserted into the side wall bolt openings 21 and the fixing column bolt openings 22 to prevent the vibrating third spring 18 from accidentally driving the sliding fixing column 19 to release the fixation of the filter frame 1001.

[0060] Please refer to Figures 1 to 7 A flushing assembly is provided on one side of the top of the box base 1 close to the second containing cylinder 9. The flushing assembly includes a water pipe 11 connected to an external water source, and a spray head 12 is connected to the output end of the water pipe 11.

[0061] In this embodiment: as the amount of filtered fruit pulp increases, a large amount of drug residue accumulates on the filter screen of the filter frame 1001 on the first station, affecting the filtering efficiency. At this time, the staff can move the filter frame 1001 to the top of the second station, and move the clean filter frame 1001 above the second station to the top of the first station, and then open the spray head 12 to clean the filter frame 1001 below.

During the vibration, the second station also vibrates, and the inverted filter frame 1001 above the second station also vibrates, thereby facilitating the filtered drug residue to fall off from the filter net.

[0065] Please refer to Figures 1-2The top end of the vibration plate 4 is connected to the bottom end of the first filling tube 5, and the fixing plate 13 is connected to the bottom end of the second filling tube 9.

[0066] In this embodiment: when the staff uses the vibration filtering device to filter the concentrated liquid, the vibration motor drives the vibration plate 4 to vibrate, and the vibration plate 4 then drives the first station and the rectangular cover 7 and the filter frame 1001 on the first station to vibrate. At this time, the rectangular cover 7 will also transmit part of the vibration to the second station. The second spring 14 under the fixed plate 13 not only plays a supporting role, but also makes the components on the first station vibrate more smoothly.
