[0002] Industrial salt refers to salt products used for industrial purposes, usually used in the manufacture of chemicals, metallurgy, leather processing, water treatment, pharmaceuticals and other industries. The preparation process of industrial salt usually involves extracting salt from seawater, lake water or underground brine, and then producing it through evaporation concentration, crystallization precipitation and other methods.
[0003] In the process of industrial salt preparation, the drying process is to remove moisture from the salt to make the salt drier, because the presence of moisture will affect the quality and performance of the salt.
[0004] In the process of industrial salt drying, various types of drying equipment are used, which are selected according to the production scale and output differences. Among them is the spiral dryer. The spiral dryer mainly relies on its internal spiral blades to transport industrial salt and heat the industrial salt during the transportation process.
[0005] However, before drying, industrial salt will partially clump due to being in a high humidity environment. The clumped industrial salt will dry out after passing through a spiral dryer, which will cause the particle size of the dried industrial salt to be uneven, reducing the overall quality of the product. To this end, we propose a drying device for preparing industrial salt. Utility Model Content

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Example 1: Please refer to Figure 1-Figure 5 A drying device for preparing industrial salt shown in the figure comprises a spiral dryer body 1, a bent pipe 5 is connected to the discharge end of the spiral dryer body 1, a discharge pipe 6 is connected to the end of the bent pipe 5 away from the spiral dryer body 1, a conical filter screen 8 is attached to the inner wall of the discharge pipe 6 near the lower edge, an elastic component is provided between the conical filter screen 8 and the discharge pipe 6, an upper connecting ring 7 and a lower connecting ring 9 are attached to the inner wall of the conical filter screen 8 near the edge from top to bottom, a lifting component is provided between the upper connecting ring 7 and the bent pipe 5, the inner ring surfaces of the upper connecting ring 7 and the lower connecting ring 9 are both conical, and the upper connecting ring 7 and the lower connecting ring 9 are symmetrically arranged, and the upper connecting ring 7 and the lower connecting ring 9 are fixedly connected.
[0022] The lifting assembly includes a fixed block 10, which is fixedly connected to the outer wall of the feeding pipe 6, and an electric push rod 4 is fixedly installed on the upper end of the fixed block 10, and the telescopic shaft end of the electric push rod 4 is fixedly connected to a connecting plate 3, which is located above the curved pipe 5, and a connecting piece is provided between the connecting plate 3 and the upper connecting ring 7.
[0023] The connecting part includes a connecting rod 2, which is fixedly connected to the lower end of the connecting plate 3 away from the electric push rod 4, and the connecting rod 2 movably passes through the inner wall of the curved pipe 5, and a fixing rod 11 is symmetrically fixedly connected to the lower edge of the outer wall of the connecting rod 2, and the ends of the two fixing rods 11 away from the connecting rod 2 are fixedly connected to the upper edge of the inner ring surface of the upper connecting ring 7.
[0024] In this embodiment, the industrial salt with humidity is put into the feeding end of the spiral dryer body 1 and is dried when it is discharged from the discharging end of the spiral dryer body 1. This is a known prior art and will not be described in detail. Subsequently, the dried industrial salt will fall into the discharge pipe 6 along the curved pipe 5, and finally the dried industrial salt will pass through the conical filter 8 and be discharged along the discharge pipe 6. In this process, the unagglomerated industrial salt will directly pass through the mesh of the conical filter 8, while the agglomerated industrial salt will not be able to pass through the mesh of the conical filter 8 and will fall along the conical surface of the conical filter 8 to the space between the outer wall of the conical filter 8 and the inner wall of the discharge pipe 6. It should be noted that the design of the conical filter 8 can prevent the agglomerated industrial salt from completely blocking it, because the agglomerated industrial salt will fall along the conical surface of the conical filter 8 to the space between the outer wall of the conical filter 8 and the inner wall of the discharge pipe 6, and the area near the tip of the surface of the conical filter 8 is still unobstructed.
[0025] After the wet industrial salt is dried, start the electric push rod 4, which can drive the connecting plate 3 to move downward, and the connecting plate 3 will drive the connecting rod 2 to slide down in the inner wall of the curved pipe 5. The connecting rod 2 will drive the upper connecting ring 7 and the lower connecting ring 9 to move downward together through the two fixed rods 11. Since the inner ring surface of the lower connecting ring 9 is set in a conical surface, the lower connecting ring 9 can finally fit exactly on the conical surface of the conical filter 8. In this process, the agglomerated industrial salt between the outer wall of the conical filter 8 and the inner wall of the discharge pipe 6 can be squeezed and crushed. The crushed agglomerated industrial salt will pass through the mesh of the conical filter 8 and be discharged from the discharge pipe 6, thereby improving the consistency of the particle size of the dried industrial salt and improving the overall quality of the product.
[0026] It should be noted that, since the inner ring surface of the upper connecting ring 7 is also set in a conical surface and is symmetrical with the inner ring surface of the upper connecting ring 7, the industrial salt will not accumulate on the upper connecting ring 7, but will slide down along the inner surface of the upper connecting ring 7.
[0027] Example 2: Please refer to Figure 2-Figure 5 The present embodiment further illustrates the first embodiment. The elastic component in the figure includes a fixing ring 12, which is fixedly connected to the inner wall of the discharge pipe 6, and the fixing ring 12 is located below the conical filter screen 8, and a plurality of connecting columns 13 are slidably inserted through the inner wall of the fixing ring 12, and the upper ends of the plurality of connecting columns 13 are fixedly connected to the lower end of the conical filter screen 8, and the outer walls of the plurality of connecting columns 13 are slidably sleeved with springs 15, and the plurality of springs 15 are fixedly connected between the fixing ring 12 and the conical filter screen 8.
[0028] The multiple connecting columns 13 and the multiple springs 15 are arranged in a circular array around the center of the fixing ring 12; specifically, the multiple connecting columns 13 and the multiple springs 15 are evenly distributed, so that the support for the conical filter screen 8 is more uniform and stable.
[0029] The lower ends of the plurality of connecting columns 13 are fixedly connected to the limiting blocks 14 , and the upper ends of the plurality of limiting blocks 14 are in contact with the lower end of the fixing ring 12 .
[0030] In this embodiment, when the lower connecting ring 9 moves downward to squeeze and crush the agglomerated industrial salt between the outer wall of the conical filter screen 8 and the inner wall of the discharge pipe 6, under the action of pressure, the conical filter screen 8 will drive the multiple connecting columns 13 to slide down in the inner wall of the fixed ring 12, and the conical filter screen 8 will squeeze the spring 15 connected to the fixed ring 12. Under the action of the spring 15, the pressure can be moved and buffered, which can prevent the conical filter screen 8 from being crushed for a long time and improve the service life of the conical filter screen 8. Secondly, when the lower connecting ring 9 moves up to return to its original position, the telescopic shaft of the electric push rod 4 can be quickly extended, and the lower connecting ring 9 can be quickly moved up and returned to its original position. At this time, under the action of the spring 15, the conical filter screen 8 and the multiple connecting columns 13 will quickly move up and return to their original position, and the limit blocks 14 under the multiple connecting columns 13 will quickly hit the lower end of the fixed ring 12, causing the conical filter screen 8 to vibrate to a certain extent, and the industrial salt adhered to the surface of the conical filter screen 8 will be shaken off, thereby improving the thoroughness of the discharge of the industrial salt and improving the permeability of the conical filter screen 8.
