Technical Field
[0001] The utility model relates to the technical field of compound food additive production, in particular to a foreign matter screening device for compound food additives. Background Technique
[0002] As is well known, a compound food additive is a formulated mixture containing two or more food additives. A compound food additive is made by physically mixing two or more single - variety food additives, with or without auxiliary materials, in order to improve food quality and facilitate food processing. There are some foreign matters in the compound food additive materials. To ensure the safety of compound food additives, it is necessary to screen and remove the foreign matters in the compound food additive materials.
[0003] Most of the existing foreign matter screening devices for compound food additives screen out the foreign matters inside the compound food additives through the filter screen inside the screening cylinder. The foreign matters in the compound food will accumulate on the upper side of the filter screen, which is likely to cause the filter screen to be blocked, and at the same time, it is not convenient to clean the foreign matters on the filter screen.

Embodiment
[0023] As Figure 1-6 shown, a foreign object screening device for compound food additives includes a sieve cylinder 1 and a base 2. Guide hoppers 19 are fixedly connected to both ends of the sieve cylinder 1 to facilitate the guiding of compound food additives or foreign objects. Two vertical plates 3 are fixedly connected to the top of the base 2. The first rotating shaft 4 is rotatably connected to both vertical plates 3. A first motor 5 for driving the rotation of the first rotating shaft 4 is installed on one vertical plate 3, and a fixing mechanism is installed on the other vertical plate 3. The sieve cylinder 1 is fixedly connected to the two rotating shafts. A collection box 20 is placed below the sieve cylinder 1 to facilitate the collection of compound food additives or foreign objects. Universal wheels 21 with self-locking functions are installed at the four corners of the bottom end of the collection box 20 to facilitate the movement of the collection box 20. A filter screen 6 is installed at the middle position inside the sieve cylinder 1. The second rotating shaft 7 is rotatably connected to the filter screen 6. Feeding plates 8 are installed on both sides of the filter screen 6 on the second rotating shaft 7. The side end of the feeding plate 8 is in contact with the side end of the filter screen 6. Regular polygon grooves 9 are provided at both ends of the second rotating shaft 7. A driving mechanism for driving the rotation of the second rotating shaft 7 is installed at the top of the two vertical plates 3;
[0024] Drive the second rotating shaft 7 to rotate through the drive mechanism. The rotation of the second rotating shaft 7 drives the rotation of a plurality of material pushing plates 8. The foreign matters on the filter screen 6 are pushed away by the material pushing plates 8, preventing the accumulation of foreign matters on the filter screen 6 and avoiding clogging of the filter screen 6. When it is necessary to clean the foreign matters inside the sieve cylinder 1, stop fixing the first rotating shaft 4 and the sieve cylinder 1 through the fixing mechanism. Drive the first rotating shaft 4 and the sieve cylinder 1 to rotate through the first motor 5, and rotate the sieve cylinder 1 by 180°. The foreign matters inside the sieve cylinder 1 will fall out and land in the foreign matter collection box 20 below the sieve cylinder 1, thus facilitating the cleaning of the foreign matters inside the sieve cylinder 1.
[0025] It should be noted that as shown in the figure, the fixing mechanism includes a circular plate 10. The circular plate 10 is fixedly connected to the corresponding first rotating shaft 4. There are two card slots 11 provided on the corresponding vertical plate 3. The two card slots 11 are respectively located on the upper side and the lower side of the first rotating shaft 4. A first electric cylinder 12 is installed on the circular plate 10. A clamping column 13 adapted to the card slot 11 is installed on the first electric cylinder 12. Push the clamping column 13 to move through the first electric cylinder 12, and insert the clamping column 13 into the corresponding card slot 11 to fix the circular plate 10, the first rotating shaft 4 and the sieve cylinder 1.
[0026] It should also be noted that as Figure 6 shown, the drive mechanism includes a second motor 14. A fixing frame 15 is fixedly connected to the tops of the two vertical plates 3. A plurality of second electric cylinders 16 are installed on the fixing frame 15. A fixing plate 17 is fixedly connected to the plurality of second electric cylinders 16. The second motor 14 is installed on the fixing plate 17. The output end of the second motor 14 is fixedly connected to a regular polygon column 18 adapted to the regular polygon groove 9. Drive the fixing plate 17 and the second motor 14 to move upward through the plurality of second electric cylinders 16, so that the regular polygon column 18 is separated from the regular polygon groove 9, facilitating the rotation of the sieve cylinder 1. Drive the fixing plate 17 and the second motor 14 to move downward through the plurality of second electric cylinders 16, so that the regular polygon column 18 is inserted into the regular polygon groove 9. Drive the regular polygon column 18, the second rotating shaft 7 and a plurality of material pushing plates 8 to rotate through the second motor 14.
[0027] The motors and electric cylinders in this embodiment are all existing devices purchased on the market, and are all equipped with corresponding control switches. The control switches are installed in appropriate positions according to the usage requirements.
[0028] In summary, when the foreign object screening device for the compound food additive is in use, the base 2 is fixed on the ground, and the top surface of the base 2 is flush with the ground. The collection box 20 for collecting the compound food additive is moved below the screening cylinder 1, and the universal wheels 21 on the collection box 20 are locked. The compound food additive to be screened is poured into the interior of the screening cylinder 1 from the upper side of the screening cylinder 1. The foreign objects inside the compound food additive are screened out by the filter screen 6, and the compound food additive falls through the mesh holes of the filter screen 6 into the interior of the collection box 20 below the screening cylinder 1. At the same time, the second motor 14 drives the regular polygon column 18, the second rotating shaft 7 and the plurality of material pushing plates 8 to rotate, and the foreign objects on the filter screen 6 are pushed away by the material pushing plates 8;
[0029] When it is necessary to clean the foreign objects on the filter screen 6, the collection box 20 for collecting the compound food additive is pushed away, and then the collection box 20 for collecting foreign objects is pushed below the screening cylinder 1. Then, the plurality of second electric cylinders 16 drive the fixed plate 17 and the second motor 14 to move upward, so that the regular polygon column 18 is separated from the regular polygon groove 9. At the same time, the first electric cylinder 12 pulls the clamping column 13 to move, so that the clamping column 13 is separated from the clamping groove 11. Then, the first motor 5 drives the first rotating shaft 4 and the screening cylinder 1 to rotate, and the screening cylinder 1 rotates 180°. The foreign objects inside the screening cylinder 1 will fall out and land in the foreign object collection box 20 below the screening cylinder 1. Then, the first electric cylinder 12 pushes the clamping column 13 to move, and the clamping column 13 is inserted into the corresponding clamping groove 11 to fix the first rotating shaft 4 and the screening cylinder 1. The plurality of second electric cylinders 16 drive the fixed plate 17 and the second motor 14 to move downward, so that the regular polygon column 18 is inserted into the regular polygon groove 9. Then, the collection box 20 for collecting foreign objects is pushed away, and the collection box 20 for collecting the compound food additive is pushed below the screening cylinder 1, and then the foreign objects in the compound food additive are continuously screened out.
