Description

Technical Field

[0001] This utility model relates to the field of chemical technology, and in particular to a high-efficiency cooling fermentation tank. Background Technology

[0002] Fermentation tanks are common fermentation containers in the chemical industry, and their temperature is typically controlled by cooling water. Current technology commonly uses a cooling jacket around the tank for water cooling. However, the cooling jacket is a complete annular cavity, preventing the cooling water from flowing evenly from the inlet to the outlet. This results in poor cooling water circulation in some areas, affecting cooling efficiency. Furthermore, the inlet pressure of the cooling water usually needs to be adjusted according to temperature control requirements during cooling. Sudden pressure changes during adjustment and normal operation are unavoidable, disrupting the balanced cooling water circulation and also affecting cooling efficiency.

[0003] Therefore, those skilled in the art are dedicated to developing a fermenter capable of efficient cooling. Summary of the Invention

[0004] In view of the above-mentioned defects in the prior art, the present invention aims to solve the technical problem of low cooling efficiency of the cooling jacket of the existing fermenter due to its own structural defects and water pressure changes.

[0005] To achieve the above objectives, this utility model provides a high-efficiency cooling fermentation tank, including a tank body and a cooling jacket around it. A continuous spiral baffle is provided in the annular cavity between the tank body and the cooling jacket. The spiral baffle divides the annular cavity into spiral channels for cooling water. The pitch of the spiral channels gradually decreases along the water flow direction. The top and bottom of the cooling jacket are respectively connected to an inlet pipe and an outlet pipe. A constant pressure pipe is connected between the inlet pipe and the outlet pipe, and a regulating valve is provided on the constant pressure pipe.

[0006] Furthermore, an inlet pressure gauge is installed on the inlet pipe, and the inlet pressure gauge is located between the constant pressure pipe and the cooling jacket.

[0007] Furthermore, a water pressure gauge is installed on the water outlet pipe, and the water pressure gauge is located between the constant pressure pipe and the cooling jacket.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] The spiral channel ensures better contact between the cooling water and the entire outer wall of the tank. As the cooling water flows along the spiral channel, its cooling capacity is gradually reduced. The varying pitch of the spiral channel enhances the fluidity of the cooling water, improving the cooling effect in the lower part of the tank and compensating for the cooling capacity loss. This results in a more balanced cooling effect between the upper and lower parts of the tank. The constant pressure pipe prevents unnecessary pressure surges when adjusting the inlet water pressure. It releases any sudden increase in inlet pressure to the outlet, achieving pressure balance between the inlet and outlet, further enhancing the stability of the cooling process and ensuring cooling efficiency.

[0013] The following description, with reference to the accompanying drawings, illustrates several preferred embodiments of the present invention to make its technical content clearer and easier to understand. The present invention can be embodied in many different forms, and the scope of protection of the present invention is not limited to the embodiments mentioned herein.

[0014] In the accompanying drawings, components with the same structure are indicated by the same numerical designation, and components with similar structures or functions are indicated by similar numerical designations. The dimensions and thicknesses of each component shown in the drawings are arbitrary, and this invention does not limit the dimensions and thicknesses of each component. To make the illustrations clearer, the thickness of some components has been appropriately exaggerated in the drawings.

[0015] like Figure 1 As shown, the high-efficiency cooling fermenter of this utility model includes a tank body 1 and a cooling jacket 2 around it. A continuous spiral baffle 3 is provided in the annular cavity between the tank body 1 and the cooling jacket 2. The spiral baffle 3 divides the annular cavity into spiral channels 4 for cooling water. The pitch of the spiral channels 4 gradually decreases along the water flow direction. The top and bottom of the cooling jacket 2 are respectively connected to an inlet pipe 5 and an outlet pipe 6. A constant pressure pipe 7 is connected between the inlet pipe 5 and the outlet pipe 6. A regulating valve 8 is provided on the constant pressure pipe 7.

[0016] Furthermore, an inlet pressure gauge 9 is installed on the inlet pipe 5, and the inlet pressure gauge 9 is located between the constant pressure pipe 7 and the cooling jacket 2.

[0017] Furthermore, a water pressure gauge 10 is installed on the water outlet pipe 6, and the water pressure gauge 10 is located between the constant pressure pipe 7 and the cooling jacket 2.

[0018] The spiral channel ensures better contact between the cooling water and the entire outer wall of the tank. As the cooling water flows along the spiral channel, its cooling capacity is gradually reduced. The varying pitch of the spiral channel enhances the fluidity of the cooling water, improving the cooling effect in the lower part of the tank and compensating for the cooling capacity loss. This results in a more balanced cooling effect between the upper and lower parts of the tank. The constant pressure pipe prevents unnecessary pressure surges when adjusting the inlet water pressure. It releases any sudden increase in inlet pressure to the outlet, achieving pressure balance between the inlet and outlet, further enhancing the stability of the cooling process and ensuring cooling efficiency.

[0019] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
