Description

Technical Field

[0001] This utility model belongs to the field of solution cooling technology, and in particular relates to a high-efficiency cooling device for cobalt acetate solution. Background Technology

[0002] Cobalt acetate solution is an important inorganic chemical product. A common preparation method is to disperse metallic cobalt powder in acetic anhydride, oxidize it by bubbling in air or oxygen in the presence of a catalyst, filter it after the reaction, dissolve the obtained cobalt salt powder in water, filter it again to remove residue, and adjust the filtrate to a weakly acidic state with acetic acid to obtain cobalt acetate solution. During the preparation of cobalt acetate solution, some reactions (such as the oxidation reaction of metallic cobalt with oxidant, the dissolution reaction of acetic acid, etc.) are accompanied by exothermic phenomena. If the reaction temperature is too high, it may lead to increased volatilization of acetic acid, decreased product purity, and even safety risks. Therefore, users usually use heat exchangers to cool it down.

[0003] Currently, heat exchangers are mostly used for cooling during the preparation of cobalt acetate solutions. During operation, the heat exchanger may experience abnormal displacement due to fluid impact loads, which can lead to loosening of the heat exchanger's connection ports. Therefore, a high-efficiency cooling device for cobalt acetate solutions is needed. This device can support and fix the heat exchanger through a support structure to prevent abnormal displacement due to fluid impact loads and ensure the sealing of the heat exchanger's connection ports. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency cooling device for cobalt acetate solution, which can support and fix the heat exchanger through a support structure, prevent abnormal displacement of the heat exchanger due to fluid impact load, and ensure the sealing of the heat exchanger connection port, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A high-efficiency cooling and temperature reduction device for cobalt acetate solution includes a spiral wound heat exchanger disposed on the right side of the tank. Two symmetrical base plates are disposed below the spiral wound heat exchanger. Two symmetrical support plates are disposed at the bottom of the spiral wound heat exchanger. Two symmetrical fixing rods are fixedly connected to the bottom of the support plates. A threaded rod is fixedly connected to the bottom of the support plates. Two symmetrical limiting sleeves are fixedly connected to the top of the base plates. The fixing rods slide within the inner cavity of the limiting sleeves. A threaded sleeve is rotatably connected to the top of the base plates. The threaded rods are threadedly connected to the threaded sleeves. A fixing ring is disposed at the top of the support plates. Two symmetrical bolts are threaded through the top of the fixing ring. The bolts pass through the fixing ring and the support plates and are threadedly connected to nuts. A chiller is disposed on the back of the spiral wound heat exchanger.

[0006] Preferably, an elastic gasket is fixedly connected to the inner cavity of the fixing ring, and the elastic gasket is in contact with the surface of the spiral wound heat exchanger.

[0007] Preferably, the spiral heat exchanger includes a shell disposed on the top of a support plate, a solution inlet on the left side of the shell connected to the outlet of a tank via a pipe, a solution outlet on the right side of the shell connected to a delivery pipe, a coolant inlet on the top of the shell connected to the outlet of a chiller via a connecting pipe, and a coolant outlet on the top of the shell connected to the inlet of a chiller via a connecting pipe.

[0008] Preferably, the inner cavity of the water cooler is filled with soft water, and two symmetrical positioning holes are provided on the top of the base plate.

[0009] Preferably, the fixing rod is a rectangular rod, and two symmetrical torsion bars are fixedly connected to the surface of the threaded sleeve.

[0010] The beneficial effects of this utility model are: 1. This utility model uses bolts to fix the base plate to the ground. By rotating the threaded sleeve, the support plate moves upward and fits against the bottom of the spiral wound heat exchanger through the limiting of the fixing rod and the limiting sleeve. The fixing ring is sleeved on the surface of the spiral wound heat exchanger and fixed with bolts and nuts. This achieves the goal of supporting and fixing the heat exchanger through the support structure, avoiding abnormal displacement of the heat exchanger due to fluid impact load, and ensuring the sealing of the heat exchanger connection port. 2. By setting up an elastic gasket, this utility model provides a certain degree of resilience to the fixing ring when it is fixed to the spiral heat exchanger. This prevents the fixing ring from breaking due to the expansion or contraction of the spiral heat exchanger caused by temperature changes, thus ensuring the safety of the fixing ring user.

A solution outlet 23 is located on the right side of the shell 21, connected to a delivery pipe. A coolant inlet 24 is located on the top of the shell 21, connected to the outlet of a chiller 10 via a connecting pipe. A coolant outlet 25 is located on the top of the shell 21, connected to the inlet of the chiller 10 via a connecting pipe. Two symmetrical base plates 3 are positioned below the wound-wound heat exchanger 2. Two symmetrical support plates 4 are positioned at the bottom of the wound-wound heat exchanger 2. Two symmetrical fixing rods 5 are fixedly connected to the bottom of the support plates 4, and threaded connections are fixedly attached to the bottom of the support plates 4. The top of the base plate 3 is fixedly connected to two symmetrical limiting sleeves 7. The fixing rod 5 slides in the inner cavity of the limiting sleeve 7. The top of the base plate 3 is rotatably connected to a threaded sleeve 8. The threaded rod 6 is threadedly connected to the threaded sleeve 8. The top of the support plate 4 is provided with a fixing ring 9. The inner cavity of the fixing ring 9 is fixedly connected to an elastic gasket 11. The elastic gasket 11 is in contact with the surface of the spiral heat exchanger 2. By setting the elastic gasket 11, when the fixing ring 9 fixes the spiral heat exchanger 2, the elastic gasket 11 will provide a certain elasticity to the fixing ring 9, so as to prevent the fixing ring 9 from breaking due to the expansion or contraction of the spiral heat exchanger 2 caused by temperature changes when fixing the spiral heat exchanger 2, thus ensuring the safety of the user of the fixing ring 9. The top of the fixing ring 9 is provided with two symmetrical bolts. The bolts pass through the fixing ring 9 and the support plate 4 and are threadedly connected with nuts. The back of the spiral heat exchanger 2 is provided with a chiller 10.

[0015] Example 2: Figure 1-4This invention illustrates an embodiment of a high-efficiency cooling and temperature-reducing device for cobalt acetate solution. It includes a wound-rotor heat exchanger 2 positioned on the right side of a tank 1. Two symmetrical base plates 3 are positioned below the wound-rotor heat exchanger 2. Two symmetrical support plates 4 are positioned at the bottom of the wound-rotor heat exchanger 2. Two symmetrical fixing rods 5 are fixedly connected to the bottom of the support plates 4. The fixing rods 5 are rectangular rods. Two symmetrical torsion bars are fixedly connected to the surface of a threaded sleeve 8. A threaded rod 6 is fixedly connected to the bottom of the support plates 4. Two symmetrical limiting sleeves 7 are fixedly connected to the top of the base plates 3. The fixing rods 5 slide within the inner cavity of the limiting sleeves 7. The threaded sleeve 8 is rotatably connected to the top of the base plates 3. The threaded rod 6 is threadedly connected to the threaded sleeve 8. A fixing ring 9 is positioned at the top of the support plates 4. Two symmetrical bolts are threaded through the top of the fixing ring 9, passing through the fixing ring 9 and the support plates 4 and threaded with nuts. A chiller 10 is positioned on the back of the wound-rotor heat exchanger 2. The inner cavity of the chiller 10 is filled with soft water. Two symmetrical positioning holes are opened at the top of the base plates 3.

[0016] Working principle: When using this utility model, the user fixes the base plate 3 to the ground with bolts, rotates the threaded sleeve 8, and causes the threaded sleeve 8 and threaded rod 6 to move threadedly. Through the limiting of the fixing rod 5 and the limiting sleeve 7, the support plate 4 moves upward and fits against the bottom of the spiral wound heat exchanger 2. The fixing ring 9 is then fitted onto the surface of the spiral wound heat exchanger 2, and the bolt passes through the fixing ring 9 and the support plate 4 and is threadedly connected to the nut. This fixes the spiral wound heat exchanger 2 with the fixing ring 9, preventing abnormal displacement of the heat exchanger due to fluid impact load and ensuring the sealing of the heat exchanger connection. When the fixing ring 9 fixes the spiral wound heat exchanger 2, the elastic gasket 11 provides a certain degree of resilience to prevent the fixing ring 9 from breaking due to the expansion or contraction of the spiral wound heat exchanger 2 caused by temperature changes, thus ensuring the safety of the user.

[0017] In summary, this high-efficiency cobalt acetate solution cooling device uses bolts to fix the base plate 3 to the ground. By rotating the threaded sleeve 8, the support plate 4 moves upward and fits against the bottom of the spiral wound heat exchanger 2 through the limiting of the fixing rod 5 and the limiting sleeve 7. The fixing ring 9 is then fitted onto the surface of the spiral wound heat exchanger 2 and fixed with bolts and nuts. This allows the heat exchanger to be supported and fixed through the support structure, preventing abnormal displacement of the heat exchanger due to fluid impact loads and ensuring the sealing of the heat exchanger connection.
