[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1-4As shown, the present invention is a filtering device for producing a refining agent, comprising a cylindrical filtering box 1, a filter screen 3 is arranged in the filtering box 1, a first rotating shaft 4 coaxially arranged with the filter screen 3 is rotatably mounted on the top wall of the filtering box 1, a scraper 5 is mounted on the bottom of the first rotating shaft 4, an arc-shaped notch 11 is arranged on the filter screen 3, an opening 10 is arranged on the side wall of the filtering box 1, a second rotating shaft 9 is embedded in the side wall of the filtering box 1, a rotating plate 6 is mounted on the bottom end of the second rotating shaft 9, the rotating plate 6 is located in the opening 10 and matches the size of the arc-shaped notch 11, a receiving plate 8 is fixed in the opening 10, and the receiving plate 8 is located below the rotating plate 6, a first unloading port 12 is opened on the rotating plate 6, a second unloading port 14 is opened on the receiving plate 8, and a transmission mechanism is arranged between the first rotating shaft 4 and the second rotating shaft 9. , and the first rotating shaft 4 is driven by an external driving source; a feed hopper 2 is connected to one side of the top of the filter box 1, and a discharge hopper is connected to the bottom of the filter box 1; the refining agent is fed into the filter box 1 through the feed hopper 2, and the filter screen 3 filters it, and the refining agent with a qualified particle size falls and is discharged through the discharge hopper, and the large particles of the refining agent are intercepted on the surface of the filter screen 3. The driving source is used to drive the first rotating shaft 4 to rotate, and the scraper 5 can scrape the refining agent flat to speed up the filtering efficiency. The large particles of the refining agent move with the scraper 5. Due to the transmission mechanism, the first rotating shaft 4 will drive the second rotating shaft 9 and the rotating plate 6 to rotate together when it rotates. When the first discharge port 12 rotates to the inside of the filter box 1, when the large particles of the refining agent move to the first discharge port 12, they will fall onto the receiving plate 8 through the first discharge port 12, which is convenient for collection and cleaning.

[0020] See also Figure 2-4 An arc-shaped baffle plate 7 is fixed on the lower surface of the filter screen 3. The baffle plate 7 can prevent the refining agent with a qualified particle size from falling on the receiving plate 8, thereby reducing waste.

[0021] See also Figure 2-4 The bottom of the first discharge port 12 is connected to a first discharge pipe 13, and the bottom of the first discharge pipe 13 contacts the surface of the receiving plate 8, and the bottom of the second discharge port 14 is connected to a second discharge pipe 15. The receiving plate 8 is provided with a plurality of discharge holes 16 in an array, and the discharge holes 16 are located inside the filter box 1. The second discharge pipe 15 rotates with the rotating plate 6, and the large particles of the refining agent will be moved to the second discharge port 14, and finally automatically discharged through the second discharge pipe 15. The discharge holes 16 have the same size as the filter holes of the filter screen 3. Even if some refining agents with qualified particle sizes fall on the receiving plate 8, they can fall through the discharge holes 16 and still be discharged through the discharge hopper.

[0022] See also Figure 1 and Figure 5The transmission mechanism includes a transmission rod 17 fixed on the first rotating shaft 4, a push block 18 is fixed on the end of the transmission rod 17 away from the first rotating shaft 4, a disc 19 is fixed on the top of the second rotating shaft 9, a plurality of transmission grooves 20 are opened on the disc 19, and the push block 18 matches the size of the transmission groove 20; the transmission rod 17 and the push block 18 rotate synchronously with the first rotating shaft 4, when the push block 18 enters the transmission groove 20, it will push the disc 19 and the second rotating shaft 9 to move, and the intermittent rotation of the rotating plate 6 is realized through this structure, reducing the time that the first discharge port 12 is located in the filter box 1, so that the refining agent with a qualified particle size can fall fully.

[0023] Example 2: In order to speed up the discharge of large-size refining agent particles, in this example, refer to Figure 6 As shown, the transmission mechanism includes a first pulley 21 installed on the first rotating shaft 4 and a second pulley 22 installed on the second rotating shaft 9, and a belt 23 is connected between the first pulley 21 and the second pulley 22; the second rotating shaft 9 is continuously rotated by belt transmission, thereby continuously discharging refining agent particles with large particle size.

[0024] The working principle of the present invention is as follows: the refining agent is fed into the filter box 1 through the feed hopper 2, and the filter screen 3 filters it. The refining agent with a qualified particle size falls and is discharged through the discharge hopper. The large particles of the refining agent are intercepted on the surface of the filter screen 3. The driving source (not shown) is used to drive the first rotating shaft 4 to rotate, and the scraper 5 can push and flatten the refining agent to speed up the filtering efficiency. The large particles of the refining agent move with the scraper 5. In the initial state, the first discharge port 12 is located outside the filter box 1. Due to the operation of the transmission mechanism, the first rotating shaft 4 When rotating, it will drive the second rotating shaft 9 and the rotating plate 6 to rotate intermittently. When the first discharge port 12 rotates to the inside of the filter box 1, the large particles of the refining agent are pushed to the first discharge port 12 by the scraper 5, and will fall onto the receiving plate 8 through the first discharge port 12, and then move to the second discharge port 14 with the first discharge pipe 13 to fall for recycling. Even if some refining agents with qualified particle sizes fall on the receiving plate 8, they will fall into the bottom of the filter box 1 through the discharge holes 16 on the receiving plate 8.

[0025] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
