[0018] In the present embodiment: the suction filtration tank 1 is provided with a plurality of filter plates 2 installed in its inner cavity, and the pressure difference generated by vacuum or negative pressure is used to accelerate the liquid to pass through the filter medium, so as to achieve solid-liquid separation, so that the mother liquor transmitted in the suction filtration tank 1 can be filtered by the plurality of filter plates 2, and the o-phenylphenol crystals can be filtered on the filter plate 2 through the filter plate 2, so that the o-phenylphenol crystals can be adsorbed on the filter plate 2, and after the filter plate 2 has retained a certain amount of the o-phenylphenol crystals, when the o-phenylphenol crystals need to be taken out, the filter plate 2 needs to be taken out from the suction filtration tank 1, so that the o-phenylphenol crystals retained on one side of the filter plate 2 are taken out together with the filter plate 2, and the filter plate is taken out by opening the device, and the mother liquor residual capacity in the device is The semi-circular plate 21 fixedly connected to the outer wall of the top of the filter plate 2 is in the clearance hole 23 opened on the outer wall of the suction filter tank 1, and the clearance hole 23 has a certain width, so that the side plate 22 fixedly connected to one side of the semi-circular plate 21 can cooperate with it to close the clearance hole 23, so that when the device is in use, the semi-circular plate 21 and the side plate 22 can ensure the normal use of the filter plate 2 in the suction filter tank 1. When the filter plate 2 needs to be taken out, the pull rod 26 is pulled so that when the pull rod 26 is pulled outward, there is a certain friction between the retaining frame 24 slidably connected to the pull rod 26 and the pull rod 26, so that the retaining frame 24 can be displaced to the position of the filter plate 2, so that the retaining frame 24 can be close to one side of the filter plate 2. The filter plate 2 is connected with the filter plate 2 by the retaining frame 24. After the retaining frame 24 is connected with the filter plate 2, the pull rod 26 can continue to be pulled outward until it is separated from the filter plate 2. When the retaining frame 24 is supported on one side of the filter plate 2, the ortho-phenylphenol crystals on the filter plate 2 are separated, and the retaining frame 26 can play a role in receiving the ortho-phenylphenol crystals. Then, the filter plate 2 is pulled upward to separate from the inner cavity of the suction filtration tank 1 through the clearance hole 23. The filter plate 2 corresponds to the semi-annular plate 21, and the width of the clearance hole 23 is larger than the width of the filter plate 2. When the filter plate 2 is pulled upward to drive the ortho-phenylphenol crystals to separate from the inner cavity of the suction filtration tank 1, the ortho-phenylphenol crystals adsorbed on one side of the filter plate 2 can be prevented from rubbing against the inner wall of the clearance hole 23, thereby breaking the ortho-phenylphenol crystals. The filter plate 2 will be pushed to separate from one side of the filter plate 2 and be mixed into the mother liquor again, which will affect the removal of the ortho-phenylphenol crystals. When the filter plate 2 moves upward, the filter plate 2 can enter the slide 31 opened in the vertical plate 3, and the inner wall of the slide 31 matches the filter plate 2, so that after the filter plate 2 is pulled to the top position of the vertical plate 3, the filter plate 2 can correspond to the discharge hole 32, and the discharge hole 32 matches the filter plate 2 and the semi-annular plate 21, so that the filter plate 2 can be taken out from the slide 31 through the discharge hole 32, so that the staff can take out the ortho-phenylphenol crystals on the filter plate 2, thereby reducing the amount of ortho-phenylphenol crystals trapped on one side of the filter plate 2 when the filter plate 2 is taken out, and reducing the loss of ortho-phenylphenol crystals.

[0019] A sealing cover 11 is installed at one end of the suction filtration tank 1, and an observation window and a feed pipe are provided on the sealing cover 11; the sealing cover 11 installed at one end of the suction filtration tank 1 is used to close the opening at one end of the suction filtration tank 1, and various pipelines are connected through the sealing cover 11, and the mother liquor is discharged into the inner cavity of the suction filtration tank 1 through the sealing cover 11. At the same time, the filtration condition of the o-phenylphenol crystals can be directly observed through the opened observation window.

[0020] A plurality of magnetic posts 241 are fixedly connected to the inner wall of the retaining frame 24, and a magnetic block 25 matching the magnetic posts 241 is provided on the filter plate 2; the plurality of magnetic posts 241 fixedly connected to the inner wall of the retaining frame 24 are used for enabling the magnetic posts 241 to be adsorbed with the magnetic block 25 provided on one side of the filter plate 2 when the retaining frame 24 is displaced to one side of the filter plate 2, so that the magnetic posts 241 can be supported on one side of the filter plate 2, so that when the o-phenylphenol crystals on the filter plate 2 are detached, they can play the role of receiving the o-phenylphenol crystals.

[0021] The suction filtration tank 1, the filter plate 2 and the retaining frame 24 are all provided with sliding holes 27 matching the pull rod 26; one end of the pull rod 26 is fixedly connected to a limiting ring 261, and an anti-skid layer is provided on the outer wall of the pull rod 26; the pull rod 26 is slidably connected through the sliding holes 27 provided on the suction filtration tank 1, the filter plate 2 and the retaining frame 24, and the anti-skid layer provided on the outer wall of the pull rod 26 can increase the friction between it and the retaining frame 24, so that when it is pulled outward, it can drive the magnetic column 241 to move to one side of the filter plate 2, so that the magnetic column 241 can be supported on one side surface of the filter plate 2.

[0022] A connecting rod 33 is slidably connected to the vertical plate 3, a connecting groove 34 is provided on the top of the side plate 22, and the bottom of the connecting rod 33 is threadedly connected to the connecting groove 34, and the vertical plate 3 and the suction filtration tank 1 are connected by a connecting block 35; the connecting rod 33 slidably connected on the vertical plate 3 can be connected to the connecting groove 34 provided on the side plate 22, so that the staff can pull the connecting rod 33 upward to make the connecting rod 33 drag the filter plate 2 to move upward, and separate the filter plate 2 from the suction filtration tank 1, so as to facilitate the removal of the ortho-phenylphenol crystals.

[0023] The working principle and use process of the utility model are as follows: when the filter plate 2 needs to be taken out so as to take out the ortho-phenylphenol crystals attached to one side thereof, the pull rod 26 is pulled to drive the retaining frame 24 to be attached to the filter plate 2. When the retaining frame 24 is supported on one side of the filter plate 2, the ortho-phenylphenol crystals on the filter plate 2 are separated, so that the retaining frame 24 can play the role of receiving the ortho-phenylphenol crystals. Then, the filter plate 2 is pulled upward to separate it from the inner cavity of the suction filtration tank 1 through the clearance hole 23. The clearance hole 23 matches the semi-circular plate 21 and the side plate 22, so that the width of the clearance hole 23 is larger than that of the filter plate 2. The width of the filter plate 2 is to prevent the o-phenylphenol crystals adsorbed on one side of the filter plate 2 from rubbing against the inner wall of the yield hole 23, thereby breaking the o-phenylphenol crystals. At the same time, the o-phenylphenol crystals will be pushed to separate from one side of the filter plate 2 and be mixed into the mother liquor again, affecting the removal of the o-phenylphenol crystals. The filter plate 2 is pulled to the position connected to the slideway 31 and the discharge hole 32, so that the staff can remove the o-phenylphenol crystals on the filter plate 2, thereby reducing the amount of o-phenylphenol crystals trapped on one side of the filter plate 2 when the filter plate 2 is taken out, thereby reducing the loss of o-phenylphenol crystals.
