[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Referring to Figures 1-4 , a filtering device of a defoaming machine includes an outer shell 1. The top of the outer shell 1 is connected and communicated with a liquid inlet pipe 2. One end of the outer shell 1 is connected and communicated with a liquid outlet pipe 3. The outer shell 1 is in a cylindrical shape with openings at both ends. The liquid outlet pipe 3 is fixedly arranged through the opening at one end of the outer shell 1, and the filtered liquid is discharged through the liquid outlet pipe 3. An inlet hole is provided on the outer wall of the outer shell 1, and the liquid inlet pipe 2 is fixedly arranged through the inlet hole, and the liquid to be filtered is introduced into the device through the liquid inlet pipe 2;

[0021] The other end of the outer shell 1 is threadedly connected to the can lid 4. The outer wall at the opening of the other end of the outer shell 1 is provided with an external thread, and the inner wall of the can lid 4 is provided with a matching internal thread. The can lid 4 is threadedly connected to the other end of the outer shell 1 through the internal thread. The can lid 4 can be firmly screwed onto the other end of the outer shell 1, ensuring the tightness and reliability of the connection. A filter screen layer 5 is installed on one side of the can lid 4. A filter membrane layer 7 is provided on the inner wall of the filter screen layer 5. An installation seat 8 is installed at the bottom end of the filter membrane layer 7. A filter element layer 6 is installed between the filter screen layer 5 and the filter membrane layer 7. A filtering gap is provided between the filter screen layer 5 and the inner wall of the outer shell 1. There is a placement gap between the filter screen layer 5 and the filter membrane layer 7. The filter element layer 6 is located in the placement gap, providing sufficient space for the filtration of the liquid. There is also a placement gap between the filter screen layer 5 and the filter membrane layer 7 to facilitate the installation and fixation of the filter element layer 6, ensuring that after the liquid passes through the filter screen layer 5, it can further pass through the fine filtration of the filter element layer 6 and the filter membrane layer 7, thus effectively improving the quality and effect of filtration.

[0022] The filter screen layer 5 and the filter membrane layer 7 are respectively in the shape of a cylinder with openings at both ends. The filter screen layer 5 and the filter membrane layer 7 are respectively located inside the outer shell 1. A number of filter holes are provided on the surface of the filter screen layer 5. The installation seat 8 installed at one end of the filter membrane layer 7 extends out of the inner wall of the filter screen layer 5. An annular clamping groove is provided at the inner wall of the opening at one end of the outer shell 1 close to the liquid outlet pipe 3. The installation seat 8 is clamped in the annular clamping groove. The filter membrane layer 7 is clamped and installed on the inner wall of the outer shell 1 through the installation seat 8. The filter screen layer 5 intercepts larger particle impurities in the liquid through the filter holes, realizing the function of preliminary filtration. The filter element layer 6 is made of activated carbon, which is used to adsorb and remove tiny particles, odors and harmful substances in the liquid, has a high filtration accuracy, and can further remove fine impurities and microorganisms. The filter membrane layer 7 has a high filtration accuracy and can further remove fine impurities and microorganisms.

[0023] When installing, align the installation seat 8 with the annular clamping groove, and then rotate and connect the can lid 4 to the outer shell 1 so that the installation seat 8 is firmly clamped in the annular clamping groove. After the liquid is preliminarily filtered by the filter screen layer 5, it further passes through the filter element layer 6 and the filter membrane layer 7 for more fine filtration, effectively removing tiny particles and harmful substances in the liquid and improving the filtration effect and the quality of the liquid. When the filtration performance of the filter screen layer 5, the filter element layer 6 and the filter membrane layer 7 decreases or reaches the service life, just rotate the can lid 4 to remove it from the outside of the outer shell 1, and pull out the filter screen layer 5, the filter element layer 6 and the filter membrane layer 7 from the inside of the outer shell 1, and take out the installation seat 8 from the annular clamping groove, then it is easy to replace the new filtering components, maintaining the filtration efficiency and stability of the filtering device.

[0024] When using this device, first place this device at the designated working position. Through the cooperation of the housing 1, the tank cover 4 and the mounting seat 8, the filtering component can be quickly disassembled for cleaning, reducing the time required for equipment maintenance, improving work efficiency, being able to clean the impurities on the filtering component in a timely manner, avoiding the blockage of the filter screen and the filter element, ensuring the filtering efficiency of the filtering device, thus ensuring the normal operation and treatment effect of the defoaming machine, reducing the wear and damage of the equipment caused by impurities, and extending the service life of the defoaming machine and the filtering device.
