DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Embodiment 1:

[0030] Reference Figure 1-Figure 5 , a liquid raw material filtering device, comprising:

[0031] Reactor 1;

[0032] The connecting pipe 101 is fixedly connected to the reaction kettle 1;

[0033] A filter assembly is fixedly connected to the connecting pipe 101;

[0034] The liquid inlet pipe 3 is fixedly connected to the filter assembly;

[0035] The first valve 301 is fixedly connected to the liquid inlet pipe 3;

[0036] The second valve 302 is fixedly connected to the liquid inlet pipe 3;

[0037] The third valve 2 is fixedly connected to the connecting pipe 101 .

[0038] The liquid inlet pipe 3 is fixedly connected to a discharge pipe 6 , and the discharge pipe 6 is fixedly connected to a fourth valve 601 .

[0039] The filter assembly includes a connecting cylinder 4 and a filter element body 7. The filter element body 7 is fixedly connected in the connecting cylinder 4. A first flange 5 is fixedly connected to the connecting cylinder 4. A second flange 1011 is fixedly connected to the connecting pipe 101. The first flange 5 is connected to the second flange 1011 by bolts 501.

[0040] A clamping ring 8 is fixedly connected to the filter element body 7, and a first magnet 801 is fixedly connected to the clamping ring 8. A connecting ring 401 is fixedly connected to the connecting tube 4, and a second magnet 4011 is fixedly connected to the connecting ring 401. The first magnet 801 and the second magnet 4011 attract each other.

[0041] The connecting tube 4 is a glass tube.

[0042] It should be noted that the connecting tube 4 is made of borax glass, which can ensure the hardness of the connecting tube 4 on the one hand, and facilitate the staff to directly observe the use of the filter element body 7 on the other hand.

[0043] A sealing gasket is provided at the connection between the first flange 5 and the second flange 1011 .

[0044] Reference Figure 1-Figure 5 , the liquid raw material is transported to the reactor 1 through the liquid inlet pipe 3. During the transportation process, the liquid raw material needs to pass through the filtering component;

[0045] During filtering, the liquid raw material will flow into the connecting tube 4 through the liquid inlet pipe 3, and the liquid raw material entering the connecting tube 4 will be filtered through the filter element body 7. After filtering through the filter element body 7, the impurity particles in the liquid raw material can be effectively filtered out.

[0046] After filtering for a period of time, when the filter element body 7 needs to be replaced, the staff can use the disassembly tool to remove the bolts 501, and then remove the filter assembly from the second flange 1011. At this time, the staff can manually rotate the filter element body 7. After the filter element body 7 is rotated to a certain angle, the first magnet 801 will no longer be attracted to the second magnet 4011. At this time, the staff can pull the filter element body 7 outward to quickly pull out the filter element body 7.

[0047] When installing a new filter element body 7, the staff can fix the clamping ring 8 on the bottom of the filter element body 7, and then push the filter element body 7 into the connecting tube 4. After pushing it in, rotate the filter element body 7. The rotation of the filter element body 7 will drive the clamping ring 8 to rotate. The rotation of the clamping ring 8 will drive the first magnet 801 to rotate. After rotating to a certain angle, the first magnet 801 will be attracted to the second magnet 4011. At this time, the filter element body 7 can be quickly installed.

[0048] By attracting the first magnet 801 on the clamping ring 8 and the second magnet 4011 on the connecting ring 401 provided in the device, the filter element body 7 can be quickly disassembled and installed, thereby improving the filtering efficiency.

[0049] It should be noted that the first magnet 801 and the second magnet 4011 are strong magnets and will not become loose due to the impact of the liquid raw material during the filtering process.

[0050] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
