Description

Technical Field

[0001] This utility model relates to the field of industrial salt production technology, specifically an evaporation and crystallization device for industrial salt production. Background Technology

[0002] Evaporation crystallization refers to the process of separating the solvent from the solute in a solution by raising the temperature, causing the solute to polymerize and turn into crystals. Industrial salt is one of the most basic raw materials in the chemical industry. It refers to crude salt, which is divided into lake salt, well salt, and sea salt. Among them, sea salt has a relatively higher industrial value and a lower edible value because the seawater in sea salt contains a variety of elements. Industrial salt has a wide range of industrial uses and is one of the most basic raw materials in the chemical industry. It is known as the "mother of the chemical industry".

[0003] In the industrial salt production process, stirring rods and scrapers are common components. The stirring rod plays a crucial role in mixing, constantly rotating and agitating to ensure thorough mixing and uniform reaction of the raw materials, thus guaranteeing the quality of the industrial salt. The scraper is equally indispensable, promptly cleaning materials adhering to the walls of the production container to prevent residue and ensure smooth production. However, under current technological conditions, the tank often only contains a simple stirring rod. When crystallization occurs on the inner wall of the tank, manual cleaning is usually required. Due to the relatively limited space within the tank, manual operation makes it difficult to reach every corner, hindering the crystallization removal process. Moreover, crystals often adhere firmly to the inner wall, making manual cleaning inefficient, time-consuming, and difficult to guarantee thorough cleaning, causing numerous problems for related production processes and operations. Utility Model Content

[0004] The purpose of this invention is to provide an evaporation and crystallization device for industrial salt production, which aims to solve the problem that it is difficult to manually clean the crystals inside the tank in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: the evaporation and crystallization device for industrial salt production includes a tank, an inlet located at the top of the tank, and an outlet pipe located at the bottom of the tank;

[0006] A rotating disk is provided inside the tank, and a rotating assembly is provided above the rotating disk. The rotating assembly drives the rotating disk to rotate about the central axis of the tank.

[0007] The rotating disk is provided with four sets of vertically penetrating limiting slots with openings facing the circumferential side, and the limiting slots are opened radially along the rotating disk.

[0008] The rotating disk is equipped with a shrinking and expanding assembly, and a first splicing piece extending in the vertical direction is connected below the shrinking and expanding assembly. Four sets of second splicing pieces extending in the vertical direction are fixedly provided on the lower surface of the rotating disk.

[0009] The second splicing component is located inside the limiting slot, and the second splicing component is in the radial direction of the rotating disk. The side of the first splicing component away from the tank is provided with an arc surface, and the side of the second splicing component facing the first splicing component is provided with an arc groove that matches the arc surface on the first splicing component.

[0010] The first splicing component is disposed in the limiting slot, and the first splicing component can move radially along the limiting slot on the rotating disk;

[0011] When the expansion and contraction assembly drives the first splice to contract along the limiting slot, the arc surface on the first splice abuts against the arc groove on the second splice to form a stirring rod structure; when the expansion and contraction assembly drives the first splice to expand along the limiting slot, the arc surface on the first splice detaches from the arc groove on the second splice, so that the opposite side of the arc surface of the first splice abuts against the inner wall of the tank.

[0012] Preferably, the rotating assembly includes a first drive motor fixedly installed on the top wall of the tank body and a rotating plate fixedly connected to the output end of the first drive motor;

[0013] The lower end of the rotating plate is fixedly connected to multiple vertically arranged connecting columns, which are fixedly connected to the upper surface of the rotating disk.

[0014] Preferably, a second drive motor is fixedly provided below the rotating plate, and the second drive motor is used to drive the expansion and contraction assembly to operate;

[0015] The expansion and contraction assembly includes a rotating plate fixedly connected to the output end of the second drive motor and a connecting rod hinged to the rotating plate;

[0016] The rotating plate is rotatably mounted on the upper surface of the rotating disk;

[0017] The connecting rod has an L-shaped structure and is divided into four groups. Each connecting rod is hinged to a sliding block, and the upper surface of the first splicing piece is fixed to the bottom of the sliding block.

[0018] The rotating plate is a square plate, and the connecting rod is hinged to the corner of the rotating plate.

[0019] Preferably, a convex-shaped limiting strip is fixedly provided on the side wall of the limiting slot, and slots adapted to the convex-shaped limiting strip are opened on both sides of the sliding block.

[0020] Preferably, the inner top wall of the tank is provided with an annular hanging groove with the opening facing downwards, and the cross-sectional shape of the annular hanging groove is an inverted convex shape.

[0021] The annular suspension groove is equipped with a suspension component, and the lower end of the suspension component is fixedly connected to the rotating plate.

[0022] Preferably, the lower end of the first splicing component is fixedly provided with an inclined plate. When the first splicing component is separated from the second splicing component, the first splicing component drives the inclined plate to abut against the inner side of the tank to clean the lower end of the inner wall of the tank. When the first splicing component and the second splicing component are spliced, the inclined plate is located inside the tank to stir the lower end of the tank.

[0023] Preferably, a support leg is fixedly provided at the bottom of the tank, and the discharge pipe is supported on the support leg.

[0024] The beneficial effects are: 1. When the expansion and contraction components act as a driving force, causing the first splice to contract along the limiting slot, the arc surface on the first splice will tightly adhere to the arc groove of the second splice, thus forming a stirring rod structure. This stirring rod structure enables effective stirring of the liquid inside the tank. During the stirring process, the liquid is fully agitated, allowing the evaporation and crystallization process inside the tank to proceed more comprehensively and thoroughly, thereby improving the overall efficiency and effectiveness of evaporation and crystallization.

[0025] 2. The expansion and contraction assembly drives the first splicing component to expand along the limiting slot. During this process, the fit between the arc surface and the arc groove between the first and second splicing components changes, and the first splicing component gradually detaches from the second splicing component. When one side of the first splicing component abuts against the inner wall of the tank, it can effectively treat the crystals on the inner wall of the tank, thus avoiding the tediousness and instability of manual cleaning and making the cleaning effect more convenient.

[0032] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0033] like Figures 1-5 As shown, an evaporation crystallization device for industrial salt production is mainly used to manually clean the crystals inside the tank 1.

[0034] In this embodiment, the evaporation crystallization apparatus includes a tank body 1, an inlet 15 located at the top of the tank body 1, and an outlet pipe 16 located at the bottom of the tank body 1. Material is poured into the tank body 1 through the inlet 15, and then the material reacts within the tank body 1. After the reaction, any remaining material is discharged through the outlet pipe 16, and the crystals are also discharged through the outlet pipe 16 after being cleared. In this embodiment, the structure and principle of the tank body 1, the inlet 15, and the outlet pipe 16 of the evaporation crystallization apparatus are all existing technologies and will not be described in detail here.

[0035] Specifically, the feed inlet 15 is located below the rotating disk 2, and a support leg 17 is fixedly provided below the tank body 1. The discharge pipe 16 is supported on the support leg 17, and the support leg 17 supports the tank body 1.

[0036] like Figure 1 , Figure 4 and Figure 5 As shown, a rotating disk 2 is rotatably installed inside the tank body 1, and a rotating assembly 3 is installed above the rotating disk 2. The rotating assembly 3 drives the rotating disk 2 to rotate around the central axis of the tank body 1. Four sets of limiting slots 4 are opened on the rotating disk 2, which are vertically penetrating and open towards the circumferential side. The limiting slots 4 are opened radially along the rotating disk 2. A shrinking and expanding assembly 5 is installed on the rotating disk 2. A first splicing piece 6 extending in the vertical direction is connected below the shrinking and expanding assembly 5. The setting of the limiting slots 4 can limit the first splicing piece 6 and prevent the first splicing piece 6 from shifting during the movement. Four sets of second splicing pieces 7 extending in the vertical direction are fixedly installed on the lower surface of the rotating disk 2.

[0037] The second splicing piece 7 is located inside the limiting slot 4, and the second splicing piece 7 is in the radial direction of the rotating disk 2. The side of the first splicing piece 6 away from the tank 1 is provided with an arc surface, and the side of the second splicing piece 7 facing the first splicing piece 6 is provided with an arc groove that matches the arc surface on the first splicing piece 6. The first splicing piece 6 is set in the limiting slot 4, and the first splicing piece 6 can move radially along the limiting slot 4 on the rotating disk 2.

[0038] When the expansion and contraction assembly 5 drives the first splicing piece 6 to contract along the limiting slot 4, the arc surface on the first splicing piece 6 abuts against the arc groove on the second splicing piece 7 to form a stirring rod structure. The stirring rod structure can stir the liquid in the tank 1, improving the efficiency of evaporation and crystallization. When the expansion and contraction assembly 5 drives the first splicing piece 6 to expand along the limiting slot 4, the arc surface on the first splicing piece 6 disengages from the arc groove on the second splicing piece 7, so that the opposite side of the arc surface of the first splicing piece 6 abuts against the inner wall of the tank 1. This can effectively treat the crystals on the inner wall of the tank 1, thereby avoiding the tediousness and instability of manual cleaning.

[0039] Specifically, such as Figure 1 As shown, the rotating assembly 3 includes a first drive motor 301 fixedly installed on the top wall inside the tank 1 and a rotating plate 302 fixedly connected to the output end of the first drive motor 301. When the first drive motor 301 is started, it can drive the rotating plate 302 to rotate. The lower end of the rotating plate 302 is fixedly connected to multiple vertically arranged connecting columns 8. The connecting columns 8 are fixedly connected to the upper surface of the rotating disk 2. When the rotating plate 302 rotates, it can drive the rotating disk 2 to rotate through the connecting columns 8.

[0040] like Figure 4 and Figure 5 As shown, a second drive motor 10 is fixedly installed below the rotating plate 302. The second drive motor 10 is used to drive the expansion and contraction assembly 5 to operate. The expansion and contraction assembly 5 includes a rotating plate 501 fixedly connected to the output end of the second drive motor 10 and connecting rods 502 hinged to the rotating plate 501. After the second drive motor 10 is started, it can drive the rotating plate 501 to rotate. When the rotating plate 501 rotates, it can drive multiple sets of connecting rods 502 to rotate synchronously. The rotating plate 501 is rotatably mounted on the upper surface of the rotating disk 2. The connecting rods 502 have an L-shaped structure and are divided into four groups. Each connecting rod 502 is hinged to a sliding block 11. The upper surface of the first splicing piece 6 is fixedly mounted on the bottom of the sliding block 11. The rotating plate 501 is a square plate. The connecting rods 502 are hinged to the corners of the rotating plate 501. When the connecting rods 502 rotate, they can drive the sliding blocks 11 to move along the limiting slot 4 to realize the contraction and expansion of the first splicing piece 6.

[0041] A convex-shaped limiting strip is fixedly provided on the side wall of the limiting slot 4. The sliding block 11 has slots on both sides that are adapted to the convex-shaped limiting strip. The convex-shaped limiting strip can limit the sliding block 11 to prevent it from tilting.

[0042] like Figure 3 As shown, an annular hanging groove 12 with its opening facing downward is provided on the inner top wall of the tank body 1. The cross-sectional shape of the annular hanging groove 12 is an inverted convex structure. A hanging member 13 is provided in the annular hanging groove 12. The lower end of the hanging member 13 is fixedly connected to the rotating plate 302. When the rotating plate 302 rotates, it can drive the hanging member 13 to slide in the annular hanging groove 12, thereby improving the suspension of the rotating plate 302 and achieving the stability of the rotating plate 302.

[0043] like Figure 1 and Figure 4 As shown, the lower end of the first splicing component 6 is fixedly provided with an inclined plate 14. When the first splicing component 6 is separated from the second splicing component 7, the first splicing component 6 drives the inclined plate 14 to abut against the inner side of the tank body 1 to clean the crystals at the lower end of the inner wall of the tank body 1. When the first splicing component 6 and the second splicing component 7 are spliced, the inclined plate 14 is located inside the tank body 1 to stir the lower end of the tank body 1.

[0044] Working principle: The material is poured into the tank 1 through the feed inlet 15. The material then reacts inside the tank 1. During the reaction, the second drive motor 10 starts, driving the rotating plate 501 to rotate. The rotation of the rotating plate 501 drives multiple sets of connecting rods 502 to rotate synchronously. As the connecting rods 502 rotate, they drive the sliding block 11 to move along the limiting slot 4, so that the arc surface on the first splicing part 6 abuts against the arc groove on the second splicing part 7 to form a stirring rod structure. At this time, the second drive motor 10 stops, and the first drive motor 301 starts, driving the rotating plate 302 to rotate. When the rotating plate 302 rotates, it drives the rotating disk 2 to rotate through the connecting column 8, allowing the rotating disk 2 to drive the stirring rod structure. The rotating mechanism stirs the liquid inside the tank 1, improving the efficiency of evaporation and crystallization. After the reaction, the remaining material is discharged from the discharge pipe 16. Then, the first drive motor 301 is stopped and the second drive motor 10 is started, driving the rotating plate 501 to rotate. The rotation of the rotating plate 501 drives the sliding block 11 to move along the limiting slot 4 through the connecting rod 502, causing the arc surface on the first splicing part 6 to disengage from the arc groove on the second splicing part 7. The arc surface of the first splicing part 6 is then placed against the inner wall of the tank 1 on the opposite side. At this time, the second drive motor 10 stops and the first drive motor 301 starts, which can drive the first splicing part 6 to rotate, effectively treating the crystals on the inner wall of the tank 1. The cleaned crystals are discharged from the discharge pipe 16.
