[0018] The present application discloses a filtering device 100, such as Figure 1As shown, the filter device 100 includes a first filter element 11 and a second filter element 12, one end of the first filter element 11 includes a first filter tube 111 penetrating the first filter element 11, the inner and outer sides of the first filter tube 111 are respectively provided with threads, the other end of the first filter element 11 includes a first plugging member 112 hinged to the first filter element 11, and a first plugging portion 113 for connecting the first filter element 11 and the first plugging member 112 is provided on the side of the first plugging member 112 away from the hinged first filter element 11, when the first filter element 11 is installed, filter cotton and other materials can be placed in the first filter element 11, after the materials are placed, the first filter element 11 closes the first plugging member 112, and the first plugging member 112 is closed by the first plugging portion 113 and a slot corresponding to the first plugging portion 113 provided on the first filter element 11. The width of the second filter element 12 is greater than that of the first filter element 11. The second filter element 12 is used to accommodate the first filter chamber. By limiting the width, the first filter element 11 can be placed in the first filter element 11. One end of the second filter element 12 includes a second filter tube 121 that penetrates the second filter element 12. The inner and outer sides of the second filter tube 121 are respectively provided with threads. The threads on the inner side of the second filter tube 121 correspond to the threads on the outer side of the first filter tube 111. The other end of the second filter element 12 includes a second plugging member 122 hinged to the second filter element 12. The second plugging member 122 is provided with a second plugging portion 123 for connecting the second filter element 12 and the second plugging member 122 on the side away from the hinged second filter element 12. The first filter element 11 is connected to the inside of the first filter element 11 through the first filter tube 111 and the second filter tube 121. The second filter element 12 and the first filter element 11 are connected through the second filter tube 121 and the first filter tube 111. The first filter element 11 is arranged inside the second filter element 12.When in use, the first filter element 11 is placed in the second filter element 12 by opening the second plugging member 122 hinged to the second filter element 12, and then connected and fixed by the corresponding threads on the second filter tube 121 and the first filter tube 111. After the first filter element 11 and the second filter element 12 are connected, the second plugging member 122 plugs the second filter element 12. After the plugging is completed, the filter device 100 can be connected to the external pipe through the threads on the inner side of the first filter tube 111 to filter the external sewage. The filter device 100 of the present application can be placed in the first filter element 11 and the second filter element 12 respectively. The filter element increases the filtering effect of the filter device 100. When it is necessary to clean the impurities in the filter element, it is only necessary to remove the external pipe through the inner thread of the first filter tube 111, and then handle the impurities in the filter device 100 by opening the second plugging member 122 and the first plugging member 112. After the first filter tube 111 and the second filter tube 121 are connected, they no longer need to be removed. Only when the first filter element 11 and the second filter element 12 fail and need maintenance, the second filter element 12 and the first filter element 11 can be removed through the second filter tube 121 and the first filter tube 111 for easy maintenance. The width of the second filter element 12 of the present application is greater than that of the first filter element 11, so it can accommodate filter elements of various sizes, such as filter elements, etc., and can flexibly increase the filtering effect of the filter device 100. When the filter device 100 of the present application needs to be cleaned of impurities, it is only necessary to disconnect the first filter tube 111 from the external pipeline through the thread on the first filter tube 111, and then open the second sealing member 122 and the first sealing member 112, so that the impurities in the filter device 100 can be easily handled, which can greatly simplify the cleaning process and reduce equipment downtime and maintenance costs.

[0019] As an implementation method, Figure 2 As shown, the filter device 100 further includes a third filter element 13, the width of the third filter element 13 is greater than that of the second filter element 12, and one end of the third filter element 13 includes a third filter tube 131 penetrating the third filter element 13, as shown in FIG. Figure 3As shown, the inner side of the third filter tube 131 is provided with threads, and the threads on the inner side of the third filter tube 131 correspond to the threads on the outer side of the second filter tube 121. The other end of the third filter element 13 includes a third plugging member 132 hinged to the third filter element 13, and the third plugging member 132 is provided with a third plugging portion 133 for connecting the third filter element 13 and the third plugging member 132 on the side away from the hinged third filter element 13. The width of the third filter element 13 is larger, and it can accommodate the second filter element 12 and the first filter element 11. The third filter element 13 also has a third filter tube 131 running through it, and the inner side of the third filter tube 131 is provided with threads, which match the outer threads of the second filter tube 121, so as to achieve the connection between the three. The other end of the third filter element 13 has a hinged third plugging member 132 for closing the third filter element 13, and the third plugging member 132 has a third plugging portion 133 on the side away from the hinge for fixing the third filter element 13 and the third plugging member 132. The third filter element 13 provides flexibility and expandability for the filter device 100. The filter device 100 can add more filter elements, such as additional filter cartridges or other filter materials, through the third filter element 13. Through the threaded connection between the third filter tube 131 and the second filter tube 121, a multi-stage filter system can be formed to meet more complex filtering requirements.

The aperture size of the first filter element 11 is larger than the aperture size of the second filter element 12, and the aperture size of the second filter element 12 is larger than the aperture size of the third filter element 13, so that the effect of multi-stage filtration can be achieved. Larger particles will first be intercepted in the first filter element 11, and smaller particles will continue to pass through the first filter element 11 and enter the second filter element 12, and finally pass through the third filter element 13 for final filtration. The design of gradually reducing the aperture can effectively capture impurities of different particle sizes and improve the filtration accuracy and efficiency.

[0021] As an implementation mode, the apertures of the first filter element 11 and the first blocking element 112 are greater than or equal to 5 mm and less than or equal to 10 mm, the apertures of the second filter element 12 and the second blocking element 122 are greater than or equal to 1 mm and less than 5 mm, and the apertures of the third filter element 13 and the third blocking element 132 are greater than or equal to 0.1 mm and less than 1 mm.

Furthermore, the pore size of the first filter element 11 and the first blocking element 112 is greater than or equal to 7 mm and less than or equal to 8 mm, the pore size of the second filter element 12 and the second blocking element 122 is greater than or equal to 2.8 mm and less than 3.2 mm, and the pore size of the third filter element 13 and the third blocking element 132 is greater than or equal to 0.5 mm and less than 0.6 mm.

[0022] As an embodiment, the outer side of the second filter element 12 includes an enclosed support member 124. The support member 124 is used to ensure the shape of the second filter element 12. The support member 124 can increase the rigidity of the second filter element 12, prevent it from being deformed due to uneven force or impact during use, and maintain the shape of the filter element stable. The stable filter element shape helps to maintain the uniform distribution of the filter pores and ensure that the filtering effect is not affected. It can be understood that the support member 124 can also be set on the outer side of the first filter element 11 to increase the supporting effect.

[0023] As an implementation manner, the first filter element 11 and the second filter element 12 are made of stainless steel.

[0024] As an implementation method, a sealing gasket is provided at the threaded connection portion of the first filter tube 111 and the second filter tube 121. The sealing gasket can fill the small gap at the threaded connection, prevent the fluid from leaking from the gap, and ensure the sealing of the filter device 100.
