Description

Technical Field

[0001] The utility model relates to a drying device for salt production, belonging to the field of edible salt production equipment. Background Art

[0002] The process of producing iodized ordinary edible salt includes moisture intake, brine making, crystallization, salt collection and salt washing. After the salt washing step is completed, it needs to be dehydrated and dried. The drying is generally carried out by vibration drying on a vibrating drying bed.

[0003] The vibrating drying bed, also called vibrating fluidized bed dryer, works on the principle of using a combination of vibration and hot air to dry the material. First, the material is fluidized on the drying bed through the vibration device to increase the contact area between the material and the hot air. Then, the hot air heats the material through the drying bed to evaporate the moisture in the material. At the same time, the continuous vibration of the vibration device can make the material tumble and spread continuously on the drying bed, ensuring that the material is evenly heated and ventilated. Finally, after a certain period of drying, the moisture in the material is completely evaporated to obtain a dry product.

[0004] In the process of drying edible salt, the smaller the salt particles are, the greater the possibility of solidification, because the larger the specific surface area, the larger the contact area between the salt particles and the air, and the easier it is to deliquesce and agglomerate. In addition, if there are many small salt particles between the large salt particles, the fine salt will repeatedly deliquesce and crystallize, causing the large salt particles to stick to each other. Therefore, it is necessary to observe the boiling of the material in the drying bed at any time, and if there is agglomeration, it should be dealt with in time.

[0005] The prior art application number is 202021831479.0, and the name of the patent application is a fluidized bed dryer for preventing material agglomeration. It reveals that the material is discharged through the discharge port after drying and then falls onto the screen of the screener. Part of the material that falls on the screen has agglomeration. At this time, the vibration motor starts, and the eccentric wheel is driven to rotate through the output shaft to hit the screen. The screen will vibrate after being hit, and the agglomerated material can be shaken away.

[0006] The existing technology is to break up the salt after drying, but since the heat transfer is not sufficient after agglomeration, the agglomerated edible salt is still slightly moist. The higher the stacking height of the edible salt and the longer the time, the easier it is to agglomerate. The screen needs to be operated repeatedly between drying, which consumes a lot of energy.

[0007] Therefore, the utility model provides a drying device for producing salt which dries and tumbles to break it up. Utility Model Content

[0008] In view of this, the purpose of the utility model is to provide a drying device for producing salt that dries and tumbles to break it up.

[0009] The utility model is achieved in this way:

[0010] A drying device for salt production, comprising a vibration unit, a drying bed, and a dispersion net, wherein the drying bed is provided with materials to be dried, the vibration unit is located directly below the drying bed and drives the drying bed to vibrate up and down, and a dispersion net is arranged above the drying bed;

[0011] The dispersion net comprises a net plate, a net frame, and fixed barbs. The net frame is composed of two parallel supporting rods, which are respectively fixed on the two long sides of the net plate. A plurality of fixed barbs are arranged at equal distances on the wide side of the net plate.

[0012] Wherein, the mesh number of the screen plate is greater than the mesh number of the drying bed.

[0013] As a further improvement, a magnetic strip is installed on the outer side of the mesh frame.

[0014] As a further improvement, the magnetic strip is made of neodymium iron boron magnet material.

[0015] As a further improvement, the mesh plate is formed by a plurality of branches intersecting each other, and the contact area of ​​the bottom end of the branches facing the drying bed is smaller than that of the other end.

[0016] As a further improvement, fixing buckles are installed at the intersection positions of the branches.

[0017] As a further improvement, the fixing buckle comprises a first buckle plate and a second fixing plate, wherein a plurality of clip strips are arranged at equal distances on the bottom end surface of the first buckle plate, and a plurality of clip slots corresponding to the clip strips are opened on the upper surface of the second fixing plate;

[0018] The first gusset plate and the second fixing plate are respectively located at the upper and lower sides of the intersection of the branches, and the clamping strip on the first gusset plate passes through the mesh plate and is clamped with the second fixing plate.

[0019] As a further improvement, it also includes a casing, a feed port, and a discharge port, wherein the feed port and the discharge port are respectively provided at two horizontal ends of the casing;

[0020] The horizontal ends of the drying bed are fixed on the inner wall of the casing through springs, and the dispersion net is also fixed on the inner wall of the casing above the drying bed through fixed barbs.

[0025] ② The magnetic strip of the utility model will be adsorbed inside the casing, and the long side length of the dispersion net is at least two meters.

[0035] Reference Figure 1-Figure 5 As shown, this embodiment provides a specific implementation method for a drying device for salt production, including a vibration unit 10, a drying bed 20, and a dispersion net 30. The drying bed 20 is placed with materials to be dried. The vibration unit 10 is located directly below the drying bed 20 and the vibration unit 10 drives the drying bed 20 to vibrate up and down. A dispersion net 30 is arranged above the drying bed 20.

[0036] The dispersion net 30 comprises a net plate 301, a net frame 302, and fixed barbs 303. The net frame 302 is composed of two parallel supporting rods, which are respectively fixed on the two long sides of the net plate 301. A plurality of fixed barbs 303 are arranged at equal distances on the wide side of the net plate 301.

[0037] The mesh number of the screen plate 301 is greater than the mesh number of the drying bed 20 .

[0038] The utility model places the edible salt material to be dried on the drying bed 20. Driven by the vibration unit 10, the material on the drying bed 20 will pass through the dispersion net 30 above when boiling and tumbling, and the edible salt will be broken up. Even if the salt particles are smaller, the specific surface area is larger, the contact area between the salt particles and the air is larger, and the drying and breaking up are performed simultaneously. The higher the stacking height of the salt is, the more tumbling and boiling are required. Similarly, the adhesion of the salt particles during the dissolution and crystallization process will also be dispersed synchronously and will not be solidified into a whole.

[0039] Furthermore, a magnetic strip 305 is installed on the outer surface of the mesh frame 302, and the magnetic strip 304 will be adsorbed on the inside of the casing 60. The long side length of the dispersion net 30 is at least two meters. In order to prevent the middle part of the dispersion net 30 from arching up at will, the material located in the middle of the drying bed 20 will not be unable to pass through the mesh plate 301 during the tumbling process, and will easily solidify into blocks.

[0040] Furthermore, the magnetic strip 305 is made of NdFeB magnet material, which has a certain tolerance to general acids and alkalis.

[0041] As a possible specific implementation of the utility model, the mesh plate 301 is formed by a plurality of branches 311 crossing each other, and the contact area of ​​the bottom end of the branch 311 toward the drying bed 20 is smaller than that of the other end. The contact area with the material is small, and it is easier to break the adhesion of relatively small salt particles, resulting in a better dispersion effect.

[0042] As a possible specific implementation of the present invention, a fixing buckle 304 is installed at the intersection of the branches 311 .

[0043] Furthermore, the fixing buckle 304 comprises a first buckle plate 341 and a second fixing plate 342, wherein a plurality of clip strips 343 are arranged at equal distances on the bottom end surface of the first buckle plate 341, and a plurality of clip slots 344 corresponding to the clip strips 343 are opened on the upper surface of the second fixing plate 342;

[0044] The first buckle plate 341 and the second fixing plate 342 are respectively located at the upper and lower sides of the intersection of the branches 311 . The clip strip 343 on the first buckle plate 341 passes through the mesh plate 301 and is engaged with the clip slot 344 of the second fixing plate 342 .

[0045] There are a number of fixing buckles 304 which are linearly installed on the mesh plate 301 to prevent the mesh plate 301 from being too long or too wide, which may cause the middle part of the mesh plate 301 to be easily deformed and arched.

[0046] The utility model further comprises a casing 60, a feed port 40, and a discharge port 50, wherein the casing 60 is provided with a feed port 40 and a discharge port 50 at both horizontal ends thereof;

[0047] The horizontal ends of the drying bed 20 are fixed to the inner wall of the casing 60 through springs 70 , and the dispersion net 30 is also fixed to the inner wall of the casing 60 above the drying bed 20 through fixing hooks 303 .

[0048] Furthermore, a plurality of inlets 601 for hot air or cold air are provided on the top of the housing 60 .

[0049] The vibration unit 10 includes a vibration shaft 101 and a vibration motor 102 . The top end of the vibration shaft 101 contacts the middle of the drying bed 20 , and the other end of the vibration shaft 101 is mechanically connected to the output end of the vibration motor 102 located on the outer side of the housing 60 .

[0050] The edible salt material of the utility model enters the drying bed 20 in the casing 60 from the feed port 40, and is driven by the vibration unit 10 to vibrate and tumble. The material passes through the dispersion net 30 and is broken up. At the same time, hot air or cold air enters from the top of the casing 60, and the material is gradually dried without being easily solidified. The dried edible salt is discharged from the discharge port 50.

[0051] In one specific embodiment, the distance between the drying bed 20 and the dispersion net 30 is 3-8 cm, which ensures that the rolling material can pass through the dispersion net 30 without affecting the rolling of the material.

[0052] The material mentioned above refers to edible salt to be dried after dehydration.

[0053] 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.
