Description

Technical Field

[0002] Salt, as one of the important substances for our survival, is crucial both in our daily cooking and in medical and health aspects. It is widely applicable in various fields such as medicine, beauty, disinfection, dental care, and decontamination.

[0003] Salt can be refined through dissolution, precipitation, filtration, and evaporation. After passing through a vibrating screen, coarse and fine salts are separated to obtain the required fine salt, and the coarse salt is redissolved. In the existing screening technology, there is a phenomenon of incomplete screening; small salt grains can pass through the mesh holes, and large salt grains remain on the screen. However, for some relatively small large salt grains, it is very likely that they will get stuck in the mesh holes and block the mesh holes, affecting the subsequent screening of salt grains and having a great impact on the screening efficiency.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0090] As Figures 1 to 14As shown in the figure, this embodiment proposes a dry salt vibrating screen with a surface cleaning mechanism, which includes a mounting frame 1, a first discharge bucket 4 and a second discharge bucket 5. There are two mounting frames 1, and the two mounting frames 1 are symmetrically arranged. The second discharge bucket 5 is installed on the side of the first discharge bucket 4.

[0095] In this embodiment, the dried salt (dry salt) is poured onto the screen mesh 15, and the vibration caused by the vibration screening mechanism enables the fine salt to pass through the screen mesh 15 and fall into the lower first discharge bucket 4, while the relatively large salt lumps remain on the screen mesh 15. Then, the cleaning and collecting mechanism collects and sweeps the large salt grains on the screen mesh 15 into the second discharge bucket 5 for subsequent re-dissolution.

[0100] a vibration module 7, which is installed between the mounting frame 1 and the load-bearing column 3. Both ends of the vibration module 7 are respectively connected to the mounting frame 1 and the load-bearing column 3.

[0101] The first mounting frame 14, and the screen 15 is mounted between the opposite sides of the two first mounting frames 14.

[0102] The driven rod 16, which is mounted at the middle position of the bottom of the first mounting frame 14, and the driven rod 16 is slidably arranged on the load-bearing column 3.

[0103] The roller 17, which is mounted at the bottom of the driven rod 16, and the roller 17 is composed of a vertical cylinder and a horizontal cylinder arranged vertically.

[0104] The second connecting column 18, there are two second connecting columns 18, and the two second connecting columns 18 are symmetrically arranged and mounted at the bottom ends of the two ends of the first mounting frame 14.

[0105] The second spring 19, there are two second springs 19, and the two second springs 19 are mounted on the two second connecting columns 18. The second spring 19 is in the vertical direction, and the second spring 19 is located on the second connecting column 18 between the load-bearing column 3 and the first mounting frame 14.

[0106] As Figures 3 to 4 shown, the vibration screening mechanism further includes a vibration driving assembly. There are two groups of vibration driving assemblies, and the two groups of vibration driving assemblies are mounted on the two mounting frames 1. The vibration driving assembly includes,

[0107] The first support plate 8, which is mounted on the mounting frame 1, and the first support plate 8 is an L-shaped plate.

[0108] The first motor 9, which is mounted on the first support plate 8.

[0118] While the screen 15 is vibrating up and down, it is vibrated by the vibration module 7, so that the load-bearing column 3 moves left and right on the first connecting column 2 under the restriction and cooperation of the first connecting column 2 and the first spring 6. The movement of the load-bearing column 3 makes the driven rod 16, the second connecting column 18 and the second spring 19 move, and makes the roller 17 slide on the first cam 13. The movement of the driven rod 16, the second connecting column 18 and the second spring 19 makes the first mounting frame 14 move, and then drives the screen 15 to shake left and right, thus realizing the left and right vibration of the screen 15, and thus realizing the up and down and left and right vibration of the screen 15. The vibration of the screen 15 enables the separation of large salt grains and fine salt grains, which is convenient for the subsequent collection and re-dissolution of large salt grains and the collection of fine salt grains.

[0158] In this embodiment, after the dry salt falls onto the screen 15, the third electric rotating shaft seat 30 provides power to rotate the second gear 39.

At the same time, the second electric rotating shaft seat 28 provides power to rotate the second rotating shaft rod 26, thereby driving the roller brush 27 to rotate. The roller brush 27 moves on the surface of the screen 15 towards the second discharge bucket 5, thus sweeping the large salt grains on the screen 15 into the second discharge bucket 5, realizing the collection of large salt grains on the screen for the re-dissolution of large salt grains;

[0160] Since salt grains may get stuck on the screen 15 during the vibration process, it is necessary to eject and collect the stuck salt blocks. At this time, the second motor 48 on the third support plate 42 provides power to rotate the spline shaft 49. The rotation of the spline shaft 49 causes the worm 50 to rotate. The rotation of the worm 50 will cause the fifth gear 52 meshed with it to rotate. Due to the limitation of the rack 54, the rotation of the fifth gear 52 will cause the worm 50 to move along the axis on the spline shaft 49. The rotation of the spline shaft 49 causes the third slider 44 to slide on the spline shaft 49. The movement of the third slider 44 drives the movement of the second mounting frame 55. When the fifth gear 52 rotates, the second cam 53 is driven to rotate synchronously through the fifth rotating shaft rod 51. Since the second cam 53 contacts the bottom of the connecting plate 46, the rotation of the second cam 53 causes the connecting plate 46 to move up and down within the second mounting frame 55 under the restriction of the locking rod 45, that is, the ejector rod 47 on the connecting plate 46 will move upward to eject the large particle salt blocks stuck in the mesh holes of the screen 15 outward, realizing the cleaning of salt grains in the screen holes and providing conditions for the collection of the ejected salt grains;

[0161] After the large salt lumps are ejected from the screen 15, the power is provided by the third electric rotating shaft seat 30 to make the second gear 39 rotate. Due to the meshing relationship between the second gear 39 and the toothed ring 20 and the installation of the third electric rotating shaft seat 30 on the second slider 29, the second slider 29 slides in the first slide rail 21, so that the third rotating shaft rod 31 moves in the first slide rail 21. The fourth electric rotating shaft seat 32 provides power to make the third rotating shaft rod 31 rotate. The rotation direction of the third rotating shaft rod 31 is counterclockwise when viewed from the side of the whole device where the arc toothed ring 20 is installed. Thus, the third rotating shaft rod 31 rotates while moving. The rotation of the third rotating shaft rod 31 makes the first bracket 33 rotate. At the same time, the electric telescopic rod 35 extends to make the second bracket 34 rotate, so that the second bracket 34 contacts the surface of the screen 15. At this time, the folding cloth 36 is opened due to the rotation of the second bracket 34. The rotation of the third rotating shaft rod 31 makes the third gear 40 rotate. The rotation of the third gear 40 makes the fourth gear 41 rotate and drives the fourth rotating shaft rod 37 to rotate. The rotation of the fourth rotating shaft rod 37 makes the strip brush 38 rotate. The strip brush 38 sweeps the large salt grains ejected from the screen holes into the space between the first bracket 33, the second bracket 34 and the folding cloth 36, realizing the collection of the salt grains ejected from the screen holes, so that the subsequent screening can be carried out in the same state, and the phenomenon of the screen holes being blocked will not occur, thus solving the problem that the screening is insufficient and multiple screenings are required, and greatly saving time.

[0162] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
