DETAILED DESCRIPTION

[0023] The following will be combined with 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 of 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.

[0024] like Figure 1~Figure 5As shown, this embodiment proposes a bag filter for organic chemicals, including a mounting frame 1, the top of the mounting frame 1 is rotatably connected to a drum 2 that penetrates the mounting frame 1, the top of the drum 2 is fixedly connected to an annular plate 3, the inner side of the annular plate 3 is slidably matched with a mounting plate 4, the bottom of the mounting plate 4 is fixedly connected to a filter bag 5, the filter bag 5 is arranged inside the drum 2, the bottom of the drum 2 is fixedly connected to a liquid outlet pipe 21, the top of the mounting plate 4 is fixedly connected to a liquid inlet pipe 41 that communicates with the inside of the filter bag 5, the outer side of the mounting plate 4 is fixedly connected to a plurality of blocks 6 that are distributed at equal angles around the mounting plate 4, the top of the annular plate 3 is provided with a plurality of positioning members 7 for positioning and fixing the blocks 6, and one end of the mounting frame 1 is provided with a driving member 8 for driving the drum 2 to rotate.

[0025] The chemical solution to be filtered is introduced into the filter bag 5 through the liquid inlet pipe 41. After being filtered by the filter bag 5, the chemical solution flows out through the liquid outlet pipe 21. The filtered impurities will remain in the filter bag 5. At the same time, the drum 2 is rotated by the driving member 8, which causes the annular plate 3 to drive the mounting plate 4 to rotate synchronously, so that the filter bag 5 is centrifugally rotated. In this way, the chemical solution can be quickly discharged from the filter bag 5 by the centrifugal force, thereby accelerating the filtration speed of the chemical solution. The impurities inside the filter bag 5 will be concentrated on the outer edge of the filter bag 5 under the action of centrifugal force, which will not affect the outflow speed of the liquid in the middle of the filter bag 5, and can greatly improve the filtration efficiency.

[0026] The locking cam 73 is pressed against the locking cam 74 at the opposite end of the locking cam 74, and the locking cam 73 is pressed against the locking cam 74 at the opposite end of the locking cam 74.

[0027] When installing, by directly matching the block 6 with the corresponding socket 71, the block 6 will apply pressure to the wedge-shaped limit block 73 to make it slide into the receiving groove 75. At this time, the spring 76 is compressed to accumulate potential energy. When the block 6 is fully matched with the corresponding socket 71, the block 6 no longer applies pressure to the wedge-shaped limit block 73. At this time, the spring 76 releases the potential energy, so that the wedge-shaped limit block 73 returns to its initial position and contacts the top surface of the block 6. This can limit the block 6 from separating from the socket 71, thereby completing the installation of the block 6, so that the mounting plate 4 and the annular plate 3 remain fixed;

[0028] During disassembly, the slide bar 72 slides by pulling the pull block 74 outward, so that the wedge-shaped limit block 73 completely slides into the storage groove 75, which makes the wedge-shaped limit block 73 completely disengaged from the block 6. In this way, the block 6 can be directly taken out, thereby realizing the rapid removal of the mounting plate 4 and the filter bag 5, which is convenient for cleaning the filter bag 5.

[0029] Furthermore, the driving member 8 includes a motor 81, which is fixedly mounted on the top of the mounting frame 1. The output shaft of the motor 81 is fixedly connected to a gear 82. The bottom end of the drum 2 is fixedly connected to a ring gear 83 meshing with the gear 82. The number of teeth of the gear 82 is smaller than the number of teeth of the ring gear 83. The gear 82 and the ring gear 83 are both located on the inner side of the mounting frame 1. The motor 81 is started to rotate the gear 82. Since the gear 82 meshes with the ring gear 83, the ring gear 83 rotates and drives the drum 2 to rotate. This causes the annular plate 3 to drive the mounting plate 4 to rotate synchronously, causing the filter bag 5 to rotate centrifugally, so that the chemical solution can be quickly discharged from the filter bag 5 under the action of centrifugal force.

[0030] Furthermore, a seal 9 is installed on the outer edge of the bottom of the mounting plate 4, and the seal 9 includes an annular airbag 91 fixedly connected to the outer edge of the bottom of the mounting plate 4, and an elastic sealing ring 92 is fixedly connected to the outer side of the annular airbag 91, and the outer side of the elastic sealing ring 92 abuts against the inner wall of the annular plate 3, and an air inlet pipe 93 for introducing gas into the annular airbag 91 is fixedly connected to the outer edge of the top of the mounting plate 4, and the outlet end of the air inlet pipe 93 is connected to the inside of the annular airbag 91, and the inlet end of the air inlet pipe 93 is fixedly connected to a gas valve 94.

[0031] When the mounting plate 4 and the annular plate 3 are slidably matched, gas is introduced into the air inlet pipe 93, which increases the internal pressure of the annular airbag 91 and causes the annular airbag 91 to expand, thereby causing the elastic sealing ring 92 to expand outward and fit tightly against the inner wall of the annular plate 3, thereby greatly improving the sealing between the mounting plate 4 and the annular plate 3.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
