[0027] Embodiment 1, a kind of filter equipment for producing polyamide resin, the filter equipment for producing polyamide resin comprises:

[0028] Specifically, a filtering device is provided inside the reactor body 1;

[0029] Further, the filtering device includes a filter screen 2, which is located in the inner cavity of the reactor body 1 and is fixedly connected to the reactor body 1. A plurality of No. 1 filter holes 22 are provided on one side of the filter screen 2 and the filter screen 2 is arranged in a "truncated cone" shape. A mounting frame 3 is slidably inserted on the side of the filter screen 2. After the material enters the reactor body 1, it will pass through the connecting plate 21 from the surface of the filter screen 2, and the impurities will flow along the filter screen 2 to the mounting frame 3. Both ends of the mounting frame 3 are slidably inserted with storage boxes 4 for collecting impurities, and a plurality of No. 2 filter holes 41 are provided on one side of the storage box 4. A plurality of No. 3 filter holes 42 are provided at the bottom of the storage box 4, and impurities flowing to the mounting frame 3 will be concentrated in the storage box 4 to ensure that the impurities will not accumulate on the surface of the filter screen 2. The No. 2 filter holes 41 and the No. 3 filter holes 42 can further allow the material to pass through the storage box 4 to ensure the utilization rate of the material. The upper end of the mounting frame 3 is fixedly connected with a connecting frame 6, and the connecting frame 6 and the filter screen 2 are slidably connected. The connecting frame 6 can be hooked by tools such as iron hooks in the prior art, and then the mounting frame 3 can be taken out, thereby taking out the storage box 4, which is very convenient.

[0030] In order to facilitate the sliding connection between the connecting frame 6 and the filter screen 2, one end of the filter screen 2 of the present application is fixedly connected to a guide rod 5 arranged in a "polygonal shape", and the side of the connecting frame 6 is provided with an insertion port 61 for the guide rod 5 to be slidably inserted and two notches 62 for facilitating the falling of materials. Through the cooperation of the polygonal guide rod 5 and the insertion port 61, it can be ensured that the trajectory of the connecting frame 6 is fixed when sliding, and the notch 62 can leak space for the falling of materials to avoid blocking the falling of materials.

[0031] In order to facilitate the connection between the filter screen 2 and the reactor body 1, the side of the filter screen 2 of the present application is fixedly connected with two symmetrically arranged connecting plates 21, and the connecting plates 21 are fixedly connected to the reactor body 1. The connecting plates 21 can facilitate the installation of the filter screen 2 and free up the installation space of the mounting frame 3 and the storage box 4.

[0032] In order to better guide impurities, the upper end of the mounting frame 3 of the present application is fixedly connected to two symmetrically arranged fixed blocks 8. The two fixed blocks 8 are both arranged to be "triangular pyramids" and correspond to the positions of the connecting plate 21. In this way, impurities falling on the connecting plate 21 can be guided into the storage box 4, and the fixed blocks 8 are placed on the connecting plate 21 to further support the mounting frame 3.

[0033] In order to facilitate the installation of the storage box 4, one end of the storage box 4 of the present application is fixedly connected with multiple iron sliders 7. The iron sliders 7 are arranged in a "T" shape and are slidably plugged with the mounting frame 3. The iron sliders 7 can facilitate the sliding installation of the storage box 4 on the mounting frame 3.

[0034] In order to ensure the stable installation of the storage box 4, a plurality of positioning grooves 31 for the sliding and plugging of the ferrous slider 7 are opened on the side of the mounting frame 3 of the present application. The positioning grooves 31 can facilitate the sliding and plugging of the ferrous slider 7. A magnet 9 is fixedly connected to the inner side of the positioning grooves 31. The magnet 9 can attract the ferrous slider 7, thereby making the installation of the storage box 4 more stable and avoiding shaking of the storage box 4 when falling.

[0035] In actual implementation, the material entering the inner cavity of the reactor body 1 will fall on the filter 2, and then the qualified material will flow through the filter 2 through the No. 1 filter eye 22, and then the impurities will slide on the curved surface of the filter 2 and then roll in the direction of the mounting frame 3, and then flow into the storage box 4, and then the impurities will be collected in the storage box 4, and the qualified material will flow out of the storage box 4 from the No. 2 filter eye 41 and the No. 3 filter eye 42, so as to avoid the waste of materials. After using it for a period of time, you can use tools such as iron hooks in the prior art to hook the connecting frame 6 and then pull out the mounting frame 3, then slide the storage box 4 out of the mounting frame 3 and pour the impurities in the storage box 4 into the impurity collection device, which is very convenient.
