Description

Technical Field

[0001] This utility model relates to the field of inorganic salt processing technology, specifically to an inorganic salt cooling device. Background Technology

[0002] In the production of inorganic salts (such as sodium chloride, potassium sulfate, sodium carbonate, etc.), material cooling and crystallization is a critical process. Traditional mainstream cooling equipment, such as jacketed stirred cooling kettles or open stirred crystallization tanks, generally have some shortcomings. First, scaling is a serious problem. On the cooling surface, due to the lowest temperature, inorganic salt crystals easily precipitate and firmly adhere to the heat exchange wall, forming a thick scale layer. This scale layer constitutes a huge thermal resistance, causing a sharp drop in heat transfer efficiency, an increase in cooling energy consumption, and requiring frequent shutdowns for manual or chemical cleaning. At the same time, it is not convenient to quickly separate the precipitated inorganic salt crystals from the waste liquid, thus affecting the continuity and efficiency of production. Therefore, this utility model proposes an inorganic salt cooling device to improve this problem. Utility Model Content

[0003] The purpose of this invention is to provide an inorganic salt cooling device in order to solve the problems mentioned in the background art.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0016] like Figures 1-9 As shown, in some embodiments of this utility model, an inorganic salt cooling device includes: Cooling tank 1, which is fixedly provided with a partition 2, which is used to divide it into a cooling chamber and a waste liquid chamber. A liquid injection pipe 3 is connected to the cooling tank 1. Preferably, the partition 2 is located on the inner bottom wall of the cooling tank 1. The cooling chamber is used to store clean water and the waste liquid chamber is used to temporarily store waste liquid. The cooling mechanism 5 includes four end plates 501 fixed to the inner wall of the cooling box 1. Vertical rods 502 slide through the end plates 501. Inclined cooling shell plates 503 are fixed to the tops of the four vertical rods 502. Cooling pipes 504 are installed inside the cooling shell plates 503. Both ends of the cooling pipes 504 are connected to the cooling chamber via delivery pipes 505. One of the delivery pipes 505 is connected to a water pump 506 installed on the cooling box 1. The cooling box 1 is equipped with a mechanism for driving the cooling shell plates 503 to reciprocate. The driving component 507 is movable. A drain pipe 508 is connected to the end of the cooling shell plate 503 with a lower inclination. Preferably, the liquid injection pipe 3 is located above the end of the cooling shell plate 503 with a higher inclination. The cooling shell plate 503 includes a cooling plate with a baffle frame. The cooling pipe 504 is a serpentine tube embedded in the cooling plate. The cooling box 1 is equipped with a refrigeration device (e.g., a high-power semiconductor refrigeration chip with its cooling end located inside the cooling chamber) for cooling the water in the cooling chamber. The delivery pipe 505 is a rubber hose. When cooling the material, the inorganic salt solution to be cooled is added through the injection pipe 3. The inorganic salt solution first flows onto the cooling shell plate 503 and then flows along the plate surface at the end with the lower inclination. Finally, it flows downward from the drain pipe 508. At this time, the refrigeration equipment cools the water in the cooling chamber. The water pump 506 performs work, which delivers the cooled water to the cooling pipe 504 through one of the delivery pipes 505, and then returns it to the cooling chamber through the other delivery pipe 505, thus forming a cold water circulation. During the circulation process, the ring transfers cold energy to the cooling shell plate 503, thereby cooling the inorganic salt solution and causing inorganic salt crystals to precipitate. At the same time, the cooling shell plate 503 is driven to slide up and down reciprocally by the driving component 507, thereby generating vibration force, which can effectively disrupt the nucleation and growth process of crystals on the surface of the cooling shell plate 503, prevent scale formation, and maintain long-term high-efficiency heat transfer. Meanwhile, by utilizing the vibration force and the inclined design of the cooling shell plate 503, inorganic salt crystals and waste liquid are discharged from the drain pipe 508. Separation mechanism 6 is installed in the waste liquid chamber. It is used to separate the inorganic salts precipitated from the waste liquid during cooling. When the inorganic salt crystals and waste liquid are discharged from the drain pipe 508 into the waste liquid chamber, the separation mechanism 6 allows the slurry to be separated immediately after cooling, which shortens the process flow, improves production efficiency, and can recover the waste liquid and inorganic salt crystals in a timely manner. In this scheme, the cooling shell plate 503 is tilted and movable inside the cooling tank 1. The solution is indirectly heated by the circulation of cold water, which cools it and causes crystals to precipitate. The driving component 507 drives the entire cooling shell plate 503 to reciprocate, which effectively prevents the crystals from adhering and forming scale on the plate surface. The cooled crystal slurry flows along the inclined plate surface to the drain pipe 508 at the lower end under the action of gravity and vibration, and is then separated by the separation mechanism 6 located in the waste liquid chamber, realizing the instant separation of crystals and waste liquid, thereby improving the continuity and efficiency of production.

[0017] like Figure 2 and Figure 8 As shown, the specific structure of the drive component 507 of this utility model is disclosed. The drive component 507 includes a rotating shaft 5071 that rotates through the cooling box 1. One end of the rotating shaft 5071 is connected to a motor 5072 installed on the cooling box 1. A cam 5073 is fixed on the rotating shaft 5071. The convex end of the cam 5073 is rotatably provided with an abutting wheel 5074 that abuts against the cooling shell plate 503. When the motor 5072 does work, its output shaft drives the rotating shaft 5071 to rotate, thereby driving the cam 5073 to rotate. Due to the structure of the cam 5073, the abutting wheel 5074 intermittently abuts against the end of the cooling shell plate 503, thereby driving the cooling shell plate 503 to move upward and then downward by gravity, thereby realizing up-and-down reciprocating movement, thereby generating vibration force to prevent scaling.

[0018] like Figure 5 As shown, a further technical solution of the present invention for the cooling shell plate 503 is disclosed. A spring 5075 sleeved on the vertical rod 502 is installed between the cooling shell plate 503 and the end plate 501. When the cooling shell plate 503 moves upward due to the contact of the cam 5073 and the contact wheel 5074 and then returns to its original position by gravity, the cooling shell plate 503 will squeeze the spring 5075. The elastic force of the spring 5075 is used to make the vibration effect of the cooling shell plate 503 better. At the same time, it also avoids the cooling shell plate 503 from hitting the end plate 501 hard when it returns to its original position, thus playing a protective role.

[0019] like Figure 3 and Figure 9The specific structure of the separation mechanism 6 of this utility model is disclosed. The separation mechanism 6 includes a mesh cylinder 601 fixed on the cooling tank 1 with one end open. A spiral conveying rod 602 is coaxially rotatably mounted on the mesh cylinder 601. A conduit 603 corresponding to the drain pipe 508 is connected to the mesh cylinder 601. A drain pipe 604 connected to the waste liquid chamber is provided on the cooling tank 1. A linkage rod 605 rotatably passes through the partition plate 2. One end of the linkage rod 605 is connected to the rotating shaft 5071 through a bevel gear assembly 606, and the other end is connected to the spiral conveying rod 602 through a universal coupling 607. Since the conduit 603 corresponds to the drain pipe 508, even if the cooling shell plate 503 moves up and down, the solution will still flow through the drain pipe 508 and the conduit 603. Preferably, the open end of the screen cylinder 601 is located outside the cooling box 1, and the outer edge of the spiral blades of the spiral conveyor 602 abuts against the inner wall of the screen cylinder 601. When the rotating shaft 5071 rotates, the linkage rod 605 is driven to rotate synchronously through the bevel gear assembly 606, and then the spiral conveyor 602 is driven to rotate synchronously through the universal coupling 607. The waste liquid falls into the waste liquid chamber through the mesh on the screen cylinder 601 and is finally discharged from the drain pipe 604. The inorganic salt crystals precipitated by cooling will be trapped in the screen cylinder 601. With the rotation of the spiral conveyor 602, the solid crystals can be pushed forward to achieve discharge, and the spiral blades can clean the crystals attached to the screen cylinder 601 to prevent the mesh from being blocked, thereby achieving the effect of solid-liquid separation.

[0020] like Figure 5 and Figure 9 As shown, the present invention discloses a further technical solution for the cooling shell plate 503. The end of the cooling shell plate 503 with a low inclination is connected to a liquid collection shell 7. The drain pipe 508 is connected to the bottom end of the liquid collection shell 7 and is inserted into the conduit 603. Since the cooling shell plate 503 will vibrate up and down, the liquid collection shell 7, as a transition collector, can effectively collect the slurry flowing down from the entire width of the cooling shell plate 503, avoiding splashing. The insertion and cooperation of the drain pipe 508 and the conduit 603 can ensure that the slurry flows smoothly into the screen cylinder 601 for solid-liquid separation, thereby improving practicality.

[0021] like Figure 6 and Figure 8 As shown, the present invention discloses a further technical solution for the cooling shell plate 503. The inner bottom wall of the cooling shell plate 503 is arrayed with several protrusions 8. The longitudinal section of the protrusions 8 is arc-shaped. By setting the protrusions 8, the effective contact area between the cooling shell plate 503 and the material is directly increased. It can also disrupt the laminar flow state of the liquid film and thin the thermal boundary layer, thereby significantly improving the heat transfer coefficient. At the same time, the protrusions 8 constitute tiny obstacles, making the liquid flow path more tortuous and prolonging the cooling and crystallization time of the material on the cooling shell plate 503, thereby improving the cooling efficiency.

[0022] like Figure 7 As shown, a further technical solution for the cooling shell plate 503 of this utility model is disclosed. A guide rod 9 is rotatably inserted through the cooling tank 1 and located below the injection pipe 3. An overflow shell 10 is fixed on the guide rod 9. An adjusting member 4 for adjusting the rotation of the guide rod 9 is provided on the cooling tank 1. By rotating the guide rod 9 and the overflow shell 10 fixed on the guide rod 9, in the initial state, the overflow shell 10 is adjusted by the adjusting member 4 so that its opening faces upward. When the solution is injected from the injection pipe 3, it will first flow into the overflow shell 10, and the solution level will rise horizontally, thus overflowing from the overflow shell 10, thereby evenly covering the entire width of the cooling shell plate 503, thus effectively utilizing the cooling shell plate 503 for cooling. When the final stage is reached, the guide rod 9 is adjusted by the adjusting member 4 so that the opening of the overflow shell 10 faces downward, thus completely pouring the solution into the cooling shell plate 503, so that there is not too much solution remaining inside.

[0023] like Figure 2 As shown, the specific structure of the adjusting component 4 of this utility model is disclosed. The adjusting component 4 includes a spur gear 401 fixed on the guide rod 9, a lead screw 402 threaded through the cooling box 1, and a rack 403 rotatably connected to the free end of the lead screw 402. The rack 403 meshes with the teeth of the spur gear 401. Twisting the lead screw 402 forces it to move, thereby driving the rack 403 to move. By utilizing the meshing of the teeth of the rack 403 and the spur gear 401, the rotation of the guide rod 9 can be adjusted. At the same time, the threaded connection between the lead screw 402 and the cooling box 1 has self-locking properties, so that the guide rod 9 can be locked after adjustment.

[0024] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
