DETAILED DESCRIPTION

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0019] like Figures 1 to 6 As shown, this utility model discloses a novel high-throughput BDO concentrator filter disc. The technical solution includes flanges 1, of which there are multiple flanges 1. Overflow holes 103 are formed on the side of each flange 1 and arranged in a circular array. Protrusions 101 are provided on each flange 1, and slots 102 are provided at the bottom of each flange 1. Two flanges 1 are connected end-to-end via the protrusions 101 and slots 102, and are bolted together and sealed using a PTFE sealing bag or silicone tape. A filter assembly 2 and a support assembly 3 are sandwiched between the two flanges 1 and sealed using a PTFE sealing bag or silicone tape. The support assembly 3 includes a main body 301, which is made of stainless steel. A central hole 302 is formed in the middle of the main body 301, and a leak is provided at the central hole 302 below the main body 301. The bottom of the funnel 303 is located below the overflow hole 103 and is sealed with a polytetrafluoroethylene sealing soft bag or silicone soft tape to ensure that the seal does not leak. The surface of the main body 301 is provided with a support boss 304. There are multiple support bosses 304 arranged in a ring array on the surface of the main body 301. The support boss 304 has a filter assembly 2. There is a locking mechanism at the edge of the filter assembly 2 and the support assembly 3. The locking mechanism includes a locking ring 4. The locking ring 4 clamps the main body 301 and the filter assembly 2 together. The locking ring 4 is divided into two halves and is provided with locking bolts 401. The two locking rings 4 are connected and fixed to each other by locking bolts 401. The locking ring 4 is provided with a support rod 402. There are multiple support rods 402 arranged in a ring array on the upper surface of the locking ring 4.
