[0002] Edible salt can be classified into well salt, sea salt, pond salt, rock salt, etc. Its ingredients include iron, calcium, zinc, potassium, sodium, iodine and other nutrients. The edible salt people use is a type of salt, which refers to salt rich in sodium, that is, sodium chloride. Salt is also an important element that the human body cannot lack, and it has the function of regulating human activities.

[0003] The production process of edible salt involves extracting sodium chloride from raw materials, then treating and processing it to finally obtain edible salt that meets food safety standards; the treatment and processing process includes collecting raw materials, dissolving, filtering, evaporating, crystallizing, harvesting, washing, centrifuging, drying, screening and packaging. In the screening step, most of the screening uses a sorting machine, which is a device that weight-grades and screens products. The material passes through a vibrating motor to vibrate the multi-layer screen to screen the material, and then it is discharged.

[0004] However, the gaps between the current screen and the frame shell are mostly filled with elastic sealing strips. However, the particles of our table salt are very small, most of them are above 100 mesh, and some can even reach above 200 mesh, while coarse salt is below 100 mesh, which can easily be embedded in the gap between the sealing strip and the screen, affecting the sealing effect.

[0033] Reference Figure 1-Figure 6 As shown, this embodiment provides a specific implementation method for a screening device for salt production, including a first frame 10, a support column 20, a second frame 30 and a spring 40, wherein the first frame 10 is in contact with the bottom surface, the four corners of the first frame 10 are vertically mounted with support columns 20, and the top of the support column 20 is supported by the spring 40, so that the second frame 30 can vibrate up and down;

[0034] The second frame 30 comprises a shell 301 and a plurality of screens 302. The top of the shell 301 is a square shell with an open end. The screens 302 are installed in parallel with each other on the inner wall of the shell 301.

[0035] The feed inlet 303 and the discharge port 304 are respectively installed at the horizontal ends of the housing 301 for feeding edible salt and the discharge port 304 after screening;

[0036] The vibration motor 305 is installed at the bottom of the housing 301 .

[0037] The edible salt material of the utility model falls into the second frame 30 through the feed port 303, and at the same time, the second frame 30 is driven by the vibration motor 305 to vibrate up and down on the top of the first frame 10. The edible salt vibrates from the feed port 303 to the discharge port 304. When it moves to the discharge port 304, the edible salt of different particle sizes is screened out through the screen 302.

[0038] In one specific embodiment, the sieve 302 has two layers, and the mesh sizes of the sieves 302 on both sides are different. The mesh size of the upper layer is smaller than that of the lower layer, and the discharge port 304 includes three, namely the first discharge port 341, the second discharge port 342 and the third discharge port 343, which screen out three edible salts of different particle sizes.

[0039] The sieve 302 comprises a sieve hole portion 321, a blocking portion 322 and a fixing portion 323. The blocking portion 322 is vertically arranged on the long side of the sieve hole portion 321 for screening edible salt, and the fixing portion 323 is horizontally welded on the outer side surface of the blocking portion 322 facing away from the sieve hole portion 321.

[0040] The mesh portion 321 and the blocking portion 322 of the sieve 302 are formed by pulling out the mesh portion 321 from a whole steel plate, and then bending the blocking portion 322 to leave an adjustment portion 324 at the edge.

[0041] That is to say, when the edible salt of the utility model moves to the edge of the screen 302, it will be blocked by the blocking part 322. The blocking part 322 is bent and has no gap. It does not need a sealing strip to block it, and there is no problem of the edible salt getting stuck in the sealing strip.

[0042] Furthermore, the sieve portion 321 is provided with a plurality of sieve holes with different diameters, and edible salt of different particle sizes can be screened out, that is, the larger the diameter of the sieve hole, the larger the edible salt particles, and conversely, the smaller the diameter of the sieve hole, the smaller the edible salt particles.

[0043] Furthermore, the sieve portion 321 is provided with an adjustment portion 324 at a distance from the bottom end of the blocking portion 322. The sieve portion 321 will bear most of the weight. If the sieve portion 321 directly supports the blocking portion 322, the edge of the sieve portion 321 will be in the shape of thin strips with equal distances, which are easy to break and affect the screening quality.

[0044] Furthermore, the surface of the adjustment portion 324 is flat and smooth, and it is easier to use tools to clean the edible salt that falls on the adjustment portion 324 during later cleaning.

[0045] The screen 302 further includes a plurality of fixed columns 325 and open columns 326 . The fixed columns 325 are welded to the inner wall of the shell 301 , and the open columns 326 are fixed to the top of the fixed columns 325 .

[0046] Furthermore, a plurality of mounting holes 323 - 1 are formed at equal intervals on the fixing portion 323 , for the opening column 326 to pass through and be fixed.

[0047] The screen 302 can be conveniently fixed and installed without screws or bolts, and can be directly snapped in place. The installation is more convenient and simple. For disassembly, the screen 302 can be directly removed by lifting it upwards one by one from the feed port 303 or the discharge port 304, thus avoiding complicated and time-consuming installation.

[0048] Furthermore, the top of the blocking portion 322 extends to the same horizontal plane as the top of the housing 301 or the adjustment portion 324 of the previous screen 302, so as to prevent the edible salt from directly passing over the screen 302 and falling into the screening space of the next layer during use.

[0049] In one specific embodiment, a top cover 306 is provided on the top of the shell 301 for shielding and facilitating the screening of edible salt.

[0050] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
