Description

Technical Field

[0001] This utility model belongs to the field of energy-saving and environmental protection technology, and specifically relates to a concentration evaporation and sewage discharge system. Background Technology

[0002] In the pharmaceutical industry, evaporation equipment is widely used for concentrating pharmaceutical solutions and recovering solvents. During the concentration process, a large amount of water vapor is generated, which needs to be promptly discharged through a wastewater system to ensure the continuity of the concentration process and the quality of the pharmaceutical solution. Traditional evaporation wastewater systems typically include a concentrator storage tank, a wastewater pump, and cooling water valves. The concentrator storage tank stores the distilled water generated during the concentration process. When the liquid level in the tank reaches a preset height, the wastewater pump automatically starts, discharging the distilled water from the system. However, the wastewater pump generates a significant amount of heat during operation. If this heat cannot be dissipated in time, the pump body temperature will become too high, affecting its service life and potentially causing damage. This also poses a risk of contaminating the pharmaceutical solution and compromising drug safety.

[0003] Currently, the common cooling method involves operators periodically inspecting the pumps and manually opening the cooling water valves based on experience to cool the sewage pumps with cooling water. However, relying on manual operation makes precise control impossible, easily leading to untimely or excessive cooling, affecting the cooling effect and posing a risk of chemical contamination. Furthermore, manual operation consumes a large amount of manpower, carries the risk of operational errors, and the continuous flow of cooling water wastes water resources, failing to meet the requirements of energy conservation and emission reduction.

[0004] Therefore, developing a concentrated evaporation and wastewater discharge system that can efficiently cool down and save water resources is of great significance for ensuring drug quality, improving production efficiency, and reducing production costs. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] This utility model provides a concentration evaporation and wastewater discharge system. Please refer to [link / reference]. Figure 1 It includes a heating unit 1, an evaporation unit 2, a condensation unit 3, a storage unit 4, a sewage pump 5, and a heat exchange unit 6;

[0028] The inlet of heating unit 1 is used to introduce liquid medicine, the bottom of heating unit 1 is connected to the bottom of evaporation unit 2, the upper outlet of heating unit 1 is connected to the upper inlet of evaporation unit 2, the top outlet of evaporation unit 2 is connected to the material inlet of condensation unit 3, the material outlet of condensation unit 3 is connected to the inlet of storage unit 4, the outlet of storage unit 4 is connected to the material inlet of sewage pump 5, and the material outlet of sewage pump 5 is used to discharge distilled water.

[0029] The cold source inlet of the condensing unit 3 is used to introduce cooling circulating water. The cold source outlet of the condensing unit 3 is connected to the cold source inlet of the sewage pump 5. The cold source outlet of the sewage pump 5 is connected to the inlet of the heat exchange unit 6. The outlet of the heat exchange unit 6 is used to output cooling circulating water.

[0030] Specifically, the liquid medicine is heated, evaporated, and concentrated in heating unit 1. The evaporated water vapor enters evaporation unit 2 and exits through the top outlet of evaporation unit 2. It is then sent to condensation unit 3 for condensation treatment to obtain distilled water. The distilled water is sent to storage unit 4 for temporary storage. When a certain liquid level is reached, sewage pump 5 is activated to discharge the liquid. Sewage pump 5 generates heat during operation, which is then used to cool the circulating cooling water in condensation unit 3. The heated circulating cooling water is sent to heat exchange unit 6 for heat exchange and cooling, and then returned to condensation unit 3 for recycling.

[0031] The concentration evaporation sewage discharge system provided by this utility model utilizes the cooling circulating water of the condensation unit 3 to cool the sewage pump 5, avoiding the consumption of additional cooling water and saving water resources. Through the coordinated work of the condensation unit 3 and the heat exchange unit 6, the cooling of the sewage pump 5 is automatically controlled, reducing manual intervention and improving operating efficiency. At the same time, the system has a compact structure, reducing the risk of external pollution and ensuring the purity of the liquid during the concentration evaporation process.

[0032] Please see Figures 2-4 Furthermore, the concentration evaporation sewage discharge system also includes: a filter unit 7;

[0033] The cold source outlet of the sewage pump 5 is also connected to the inlet 703 of the filter unit 7, and the outlet 704 of the filter unit 7 is connected to the inlet of the heat exchange unit 6.

[0034] By adding a filter unit 7, impurities (such as drug residues, particulate matter, etc.) in the cooling circulating water can be effectively removed, preventing impurities from entering the heat exchange unit 6 and the sewage pump 5, thus avoiding equipment blockage or wear. The filtered cooling circulating water has better flow and higher heat exchange efficiency, further optimizing the cooling effect of the sewage pump 5.

[0035] In one specific implementation, valves are respectively installed on the pipeline connecting the cold source outlet of the sewage pump 5 to the inlet of the heat exchange unit 6, and on the pipeline connecting the cold source outlet of the sewage pump 5 to the inlet 703 of the filter unit 7.

[0036] In one specific implementation, the filter unit 7 includes a housing 701 and a plurality of filter layers 702 installed in the housing 701. The plurality of filter layers 702 are arranged on the path of the cooling circulating water from the inlet 703 to the outlet 704 for filtering and purifying the cooling circulating water.

[0037] Multiple filter layers 702 can perform graded filtration of impurities of different particle sizes to ensure the purity of cooling circulating water. The type and number of filter layers 702 can be flexibly configured according to the characteristics of impurities in the cooling circulating water to meet the needs of different operating conditions.

[0038] Furthermore, the filter unit 7 also includes a disassembly cover 705 and a plurality of mounting rods 708. The disassembly cover 705 is installed on one side of the housing 701, and the plurality of mounting rods 708 are disposed inside the housing 701. The inner outer edge of the disassembly cover 705 is fixedly connected to one end of the plurality of mounting rods 708, and the other end of the plurality of mounting rods 708 is a free end. The plurality of filter layers 702 are inserted into the mounting rods 708.

[0039] The design of the disassembly cover 705 makes the maintenance of the filter unit 7 and the replacement of the filter element 711 more convenient, reducing downtime; and the filter layer 702 is fixed by the mounting rod 708 to ensure that the filter layer 702 will not shift or fall off during operation, improving system stability. At the same time, the plug-in installation method of the filter layer 702 facilitates quick assembly and disassembly, making it suitable for mass production and maintenance.

[0040] Specifically, the disassembly cover 705 is tightly connected to the housing 701 via the connecting part 706. In order to enhance the sealing of the filter unit 7, a rubber gasket 707 can also be added at the connection between the disassembly cover 705 and the housing 701.

[0041] Optionally, the multiple filter layers 702 include a filter element 711 and mounting holes 712 on the outer edge of the filter element 711; the mounting rod 708 is provided with multiple locking blocks 709 corresponding to the size of the mounting holes 712 in the direction of the inner wall of the housing 701, and the multiple mounting holes 712 are inserted into the mounting rod 708 through the locking blocks 709.

[0042] The design of the locking block 709 ensures that the filter layer 702 is firmly fixed to the mounting rod 708, preventing it from loosening due to water flow impact; this further simplifies the installation and replacement process of the filter layer 702 and improves operational efficiency.

[0043] Furthermore, a limiting plate 710 is connected to the side of the locking block 709 near the disassembly cover 705. The length of the limiting plate 710 is greater than that of the locking block 709 connected to it. In the direction from the free end of the multiple mounting rods 708 to the disassembly cover 705, the length of the multiple locking blocks 709 gradually increases, and the length of the multiple limiting plates 710 also gradually increases.

[0044] By gradually increasing the length of the limiting block 709 and the limiting plate 710, the mounting hole 712 of the filter layer 702 can be smoothly inserted into the mounting rod 708 layer by layer through the front end of the limiting block 709 and the limiting plate 710, further improving the convenience of installation and replacement.

[0045] In one specific embodiment, there are four mounting rods 708, which are evenly and symmetrically distributed.

[0046] Optionally, the filter element 711 includes at least one of activated carbon, resin, PP melt-blown filter element 711, and ceramic. The PP melt-blown filter element 711 can remove large particulate impurities, while the activated carbon filter element 711 or resin filter element 711 can remove impurities such as drug residues and inorganic salt crystals.

[0047] In one specific embodiment, in the direction from the free end of the plurality of mounting rods 708 to the disassembly cover 705, the first filter layer 702 is selected as a PP melt-blown filter element 711, the second filter layer 702 is selected as an activated carbon filter element 711 or a resin filter element 711, and the third filter layer 702 is selected as a filter element 711 with a filtration accuracy of not less than 0.01μm.
