[0032] Example: Reference Figure 1-7 A filtering device for feed additive production shown in the figure comprises a filter box 1, an upper function plate 2 and a lower function plate 3 are respectively provided on the left and right sides of the filter box 1, electric gates 4 are embedded and installed inside the upper function plate 2 and the lower function plate 3, the filtering channel in the filter box 1 is separated into a first inspection chamber 5 and a second inspection chamber 6 by the gate plates of the two electric gates 4, a first filter component 12 and a second filter component 13 of the same structure are respectively rotatably connected in the first inspection chamber 5 and the second inspection chamber 6, a first closing plate 7 and a second closing plate 8 are respectively slidably matched in the first inspection chamber 5 and the second inspection chamber 6, the first filter component 12 and the second filter component 13 are vertically arranged with each other, and the first filter component 12 and the second filter component 13 are connected by a transmission mechanism, a servo motor 9 for driving the transmission mechanism is fixedly installed on one side of the filter box 1, a feed inlet is provided at the top of the filter box 1, a discharge port is provided at the bottom of the filter box 1, and four support columns are fixed at the bottom of the filter box 1.

[0033] During actual use of the device, when the first filter assembly 12 is in a horizontal state, the second filter assembly 13 is in a vertical state and is located inside the second inspection chamber 6, the gate of the electric gate 4 in the upper functional panel 2 is lowered to isolate the second inspection chamber 6 from the filter channel in the filter box 1, and the first closing plate 7 slides toward the inside of the first inspection chamber 5, and the lower surface of the first closing plate 7 slides in contact with the upper surface of the first filter assembly 12, thereby closing the first inspection chamber 5 to prevent the feed additive from escaping through the first inspection chamber 5, and the feed additive is poured into the filter box 1 through the feed inlet. Inside, the first filter component 12 filters the feed additives by vibration, and the filtered feed additives are discharged through the discharge port. During this period, the staff can inspect and maintain the second filter component 13 in the second inspection room 6 when the device is in operation; when the first filter component 12 reaches the working time and needs to be inspected, the feeding is suspended, the gate of the electric gate 4 in the upper function panel 2 is recovered, the first closing plate 7 slides out of the first inspection room 5, and the servo motor 9 drives the transmission mechanism to operate, and the transmission mechanism drives the second filter component 13 to rotate 90° counterclockwise to a horizontal position. The first filter assembly 12 rotates 90° clockwise to a vertical state. At this time, the first filter assembly 12 is completely located in the first inspection chamber 5. The gate of the electric gate 4 in the lower functional panel 3 rises vertically to isolate the first inspection chamber 5 from the filter channel in the filter box 1. The second closing plate 8 slides toward the inside of the second inspection chamber 6. The top of the second closing plate 8 slides in contact with the lower surface of the second filter assembly 13, which plays a role in supporting the second filter assembly 13 and also completely closes the second inspection chamber 6 to prevent the feed additive from escaping through the second inspection chamber 6. At this time, feeding starts again and is in a horizontal position. The second filter component 13 in the state filters the feed additives by vibration. Since the first inspection room 5 and the filter channel in the filter box 1 are separated by the gate plate of the electric gate 4, the staff can inspect and maintain the first filter component 12 in the first inspection room 5 when the device is in operation; the first filter component 12 and the second filter component 13 can filter the feed additives alternately, and the operation of the device will not affect the inspection and maintenance work of the first filter component 12 / second filter component 13 entering the first inspection room 5 / second inspection room 6.

[0034] In order to achieve the linkage between the first filter assembly 12 and the second filter assembly 13, in this embodiment, the transmission mechanism includes a rotating rod 14 rotatably connected to one side of the filter box 1, and a first gear 15 is fixedly sleeved on the side surface of the rotating rod 14. The rotating shafts of the first filter assembly 12 and the second filter assembly 13 both pass through the filter box 1 and are respectively fixedly connected to the second gear 18 and the sprocket 16. A similar sprocket 16 is fixed to one end of the rotating rod 14, and the two sprockets 16 are connected by a chain transmission. The first gear 15 is meshed with the second gear 18, and the output end of the servo motor 9 is fixedly connected to a sprocket 16. When the servo motor 9 drives the sprocket 16 to rotate 90° in the opposite direction, the second filter component 13 will rotate counterclockwise to a horizontal position. Through the transmission of the chain 17, the two sprockets 16 will rotate 90° synchronously, driving the first gear 15 to rotate 90° synchronously. Due to the meshing connection between the first gear 15 and the second gear 18, the second gear 18 will rotate 90° in the opposite direction synchronously, thereby driving the first filter component 12 to rotate 90° clockwise, so that the first filter component 12 and the second filter component 13 rotate synchronously. The servo motor 9 controls the sprocket 16 to rotate 90° forward or reversely, so that the first filter component 12 and the second filter component 13 are alternately in a horizontal state, and the feed additives are filtered alternately.

[0035] In order to achieve vibration filtration of feed additives, in this embodiment, the first filter assembly 12 includes a swing plate 121, and one end surface of the swing plate 121 is slidably matched with a mounting cross plate 127 that can vibrate vertically. A filter plate 128 is fixed to one side of the mounting cross plate 127. The rotating shaft of the swing plate 121 passes through the filter box 1 and is fixedly connected to the second gear 18. A groove 122 is opened at one end of the swing plate 121, and a plurality of guide rods 123 are fixed in the groove 122. A movable plate 124 is slidably sleeved on the side surface of the guide rod 123. Springs 125 are fixed between the upper and lower surfaces of the movable plate 124 and the two groove walls of the groove 122. A plurality of vibration motors 126 are fixedly installed on the upper surface of the movable plate 124, and the movable plate 124 is fixedly connected to the mounting cross plate 127. When the first filter assembly 12 is in a horizontal state, the filter plate 128 of its filtering part is located in the filter channel, and the peripheral side surface of the filter plate 128 is in sliding contact with the inner wall of the filter box 1 and the side wall of the upper functional plate 2. When the vibration motor 126 vibrates, since the movable plate 124 is sleeved on the outer side of the guide rod 123, and springs 125 are fixed between the upper and lower surfaces of the movable plate 124 and the two groove walls of the groove 122, the movable plate 124, the installation cross plate 127 and the filter plate 128 are simultaneously vertically reciprocated up and down to achieve vibration filtration of feed additives. When the second filter assembly 13 is in a horizontal state, the filter part of the second filter assembly 13 is also located in the filter channel, and the filter part of the second filter assembly 13 is in sliding contact with the inner wall of the filter box 1 and the side wall of the lower functional plate 3.

[0036] In this embodiment, a first electric push rod 10 and a second electric push rod 11 are fixedly installed on the back of the filter box 1, and the output ends of the first electric push rod 10 and the second electric push rod 11 are respectively fixedly connected to the first closing plate 7 and the second closing plate 8 through the connecting rod 19.
