Description

Technical Field

[0001] This utility model relates to the field of disc dryer technology, and more specifically, to an industrial waste salt disc dryer. Background Technology

[0002] The disc-type waste salt dryer conducts heat (heat transfer oil / steam) through multiple layers of hollow heating discs. The material flows layer by layer along a spiral path driven by rake blades, achieving continuous conductive drying. Its core advantages are: thermal efficiency exceeding 60%, reducing energy consumption by 30% compared to convection drying; a sealed design suitable for vacuum operation, allowing simultaneous processing of high-COD waste salt and solvent recovery; and an intelligent temperature control system ensuring moisture content fluctuations are less than ±0.5%, meeting pharmaceutical / food-grade cleanliness requirements.

[0003] However, the current waste salt still needs to be separated after drying to further separate the various components of the waste salt for subsequent use. However, the current disc dryer produces waste salt with large particle size and agglomerates after drying, which is not conducive to subsequent separation. In addition, the material is usually discharged directly, which is not conducive to the drying and collection of large quantities of waste salt. Utility Model Content

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] To address the problem that current disc dryers produce waste salt with large particle sizes and agglomeration after drying, which is detrimental to subsequent mass fractionation, Example 1 is proposed: Please see Figures 1-4 This utility model discloses an industrial waste salt disc dryer, comprising a dryer body 1. The dryer body 1 includes a feeding mechanism 2, a tank 3, a heat source connecting pipe 4, a heating disc assembly 5, a pushing mechanism 6, a pressing mechanism 7, and a discharge valve pipe 9. The feeding mechanism 2 is installed on the tank 3 for inputting waste salt. One end of the heat source connecting pipe 4 extends into the interior of the tank 3 to heat the interior of the heating disc assembly 5, and the other end of the heat source connecting pipe 4 is connected to an external heat source equipment circulation pipe. The heating disc assembly 5... The feeding mechanism 6 is fixedly installed inside the tank body 3. It is used to push the waste salt to fall alternately layer by layer along the heating plate group 5. The pressing mechanism 7 is installed at the bottom of the tank body 3 to crush and discharge the dry waste salt and discharge it through the discharge valve pipe 9. The feeding mechanism 2 includes a feeding hopper 21, a horizontal hinge 22 and a feeding hopper 23. The bottom of the feeding hopper 21 is connected and fixed to the top of the tank body 3. The discharge end of the horizontal hinge 22 extends into the interior of the feeding hopper 21. The feeding hopper 23 is located at the top of the horizontal hinge 22.

[0016] The feeding mechanism 6 includes a drive motor 61, a shaft 62, and vertically arranged rakes 63. The drive motor 61 is fixedly installed on the top of the tank 3. The output end of the drive motor 61 is fixedly connected to the shaft 62 through a coupling. The shaft 62 passes downward through the heating plate assembly 5 and extends into the interior of the tank 3. The rakes 63 are fixedly installed on the outside of the shaft 62 and correspond to and contact the plate surfaces of the heating plate assembly 5.

[0017] In this embodiment, the waste salt is continuously mechanically fed into the tank 3 by the starting feeding mechanism 2. Then, the drive motor 61 is started to drive the shaft 62 to rotate, which drives the rake 63 to spread and push the waste salt on each layer of heating plate group 5, so that it can fully contact the heating plate group 5 to achieve drying. The heat source connection pipe 4 is used to connect the external heat source into the interior of the heating plate group 5 to achieve heating and drying. After the waste salt is completely dried as it falls layer by layer, it falls into the pressing mechanism 7 area at the bottom of the tank 3. At this time, the pressing mechanism 7 is started to squeeze and discharge the dried waste salt by rotation, crushing the large clumps to make the particles uniform, which is convenient for subsequent quality separation. Thus, the device has the advantages of squeezing and crushing waste salt after drying to make the particles uniform, and is compatible with the subsequent screening operation.

[0018] Please see Figure 4 The pressing mechanism 7 includes a geared motor 71, a rotating shaft 72, two pressure rollers 73, and a feeding block 74. The geared motor 71 is fixedly installed at the bottom of the tank body 3. The output end of the geared motor 71 is fixedly connected to the rotating shaft 72 through a coupling. The top end of the rotating shaft 72 passes through and is rotatably connected to the inside of the tank body 3. One end of the pressure roller 73 is rotatably connected to the outside of the rotating shaft 72 and is parallel to the bottom surface of the tank body 3. One end of the feeding block 74 is fixedly connected to the outside of the rotating shaft 72. The bottom of the feeding block 74 is in parallel sliding contact with the bottom surface of the tank body 3.

[0019] The bottom of the inner side of the tank body 3 is provided with an annular groove 8. The outer side of the rotating shaft 72 revolves along the inside of the annular groove 8 and contacts its surface to generate rotation. The inside of the annular groove 8 is provided with an inclined guide groove 81, which is connected to the discharge valve pipe 9.

[0020] In this embodiment, the geared motor 71 is started to drive the rotating shaft 72 to rotate, thereby driving the pressure roller 73 to revolve along the inside of the annular groove 8 while crushing the waste salt clumps that fall, making the clumps uniform. At the same time, the feeding block 74 rotates synchronously to push the crushed waste salt into the inclined guide trough 81 and finally drop it into the discharge valve pipe 9 for discharge.

[0021] Furthermore, considering the common practice of directly discharging waste salt, which hinders the drying and collection of large quantities of waste salt, Example 2 is proposed: Please see Figure 1 The tank body 3 is provided with an inclined guide hinge 10 at the bottom, which corresponds to and cooperates with the discharge valve pipe 9. The discharge end of the inclined guide hinge 10 extends upward and is provided with a receiving bin 11 below.

[0022] In this invention, the waste salt discharged from the discharge valve pipe 9 is discharged through the inclined guide hinge 10 and transported to the inside of the receiving bin 11 for unified collection.

[0023] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
