Description

Technical Field

[0001] The utility model relates to a cooling device for drug extraction, belonging to the field of drug production equipment. Background Art

[0002] Drug extraction is a process of extracting the active ingredients of drugs from natural substances such as animals, plants and minerals. Rabdosia rubescens is one of them; the oridonin of Rabdosia rubescens has unique advantages in treating diseases, so the extraction of oridonin components has attracted much attention. Drug extraction methods include solvent method, distillation method and sublimation method. The latter two methods have narrow application ranges and high energy consumption, so they cannot be widely used. The solvent method is mostly used in industry to extract drugs.

[0003] The solvent method is to select an appropriate solvent to extract the oridonin from Rabdosia rubescens, and then concentrate the feed liquid, and finally extract the high-concentration drug. Therefore, the solvent method drug extraction device generally includes an extraction tank and a concentrator. After the active ingredients in the medicinal materials are extracted by the solvent in the extraction tank, the solvent in the extraction liquid is evaporated by the concentrator, so as to extract the high-concentration drug.

[0004] In the prior art, when extracting drugs, usually a solvent is used to extract the drugs. During extraction, it takes a lot of time to extract the feed liquid, and a large amount of heat will be generated during the concentration process after the extracted feed liquid enters the concentrator, so it is necessary to cool it down; so cooling water needs to be introduced for cooling. After these cooling waters cool down the extraction equipment, they still need to be recycled. Therefore, in order to make the recycling of cooling water more convenient, it is necessary to cool down the heated cooling water so as to supply continuous cooling water to the extraction equipment. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a cooling device for drug extraction, which can effectively solve the above problems.

[0006] In order to solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] It includes a cooling tower; the cooling tower sequentially includes a cooling space, an evaporation space and a heat exchange space which are connected to each other from top to bottom; a cooling coil is arranged in the cooling space, one end of the cooling coil is connected with a water inlet pipe, and the other end is connected with a water outlet pipe; a spraying assembly is arranged above the cooling coil; the periphery of the evaporation space is communicated with the outside of the cooling tower through a through groove; heat exchange packing is filled in the heat exchange space.

[0008] A diversion fan is further arranged outside the evaporation space.

[0009] Further: The spraying assembly includes a main spraying pipe and a number of secondary spraying pipes arranged at the front and rear ends of the main spraying pipe. Sprayers are provided at the lower ends of the secondary spraying pipes.

[0010] Further: The through groove of the evaporation space is formed by an inclined air guiding plate, and the inclination angle of the air guiding fan is the same as that of the air guiding plate.

[0011] Further: A liquid collecting space is also provided below the heat exchange space at the bottom of the cooling tower. The liquid collecting space is communicated with the outside through an output pipe.

[0012] Further: The main spraying pipe is communicated with the output pipe, and a water pump is provided at the connection between the main spraying pipe and the output pipe.

[0013] The beneficial effects are as follows:

[0014] This device can not only realize the recycling of cooling water, but also realize the recycling of coolant. Because after the coolant is sprayed on the cooling coil, it will absorb the heat of the cooling water, resulting in an increase in the temperature of the coolant; and the coolant with increased temperature is obviously not suitable for further use; while this device is provided with a heat exchange space, which can absorb the heat carried by the coolant through heat exchange packing, and at the same time the heat is converted into gas and blown out of the cooling tower by the air guiding fan outside the evaporation space.

Detailed Embodiments

[0022] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0023] Refer to Figures 1-4 This is an embodiment of a cooling and temperature reduction device for drug extraction of the present utility model.

[0024] It includes a cooling tower 1; inside the cooling tower 1, there are successively arranged from top to bottom a cooling space 2, an evaporation space 3, and a heat exchange space 4 that are interconnected; a cooling coil 5 is arranged in the cooling space 2, one end of the cooling coil 5 is connected to a water inlet pipe 6, and the other end is connected to a water outlet pipe 7; a spraying assembly 8 is arranged above the cooling coil 5; the periphery of the evaporation space 3 is communicated with the outside of the cooling tower 1 through a through groove 15; a heat exchange filler 9 is filled in the heat exchange space 4.

[0025] When the cooling tower 1 of this device is in use, first, the high-temperature cooling water flowing through the drug extraction tank is introduced into the cooling coil 5 through the water inlet pipe 6. At this time, the temperature of the cooling coil 5 rises due to the passage of the high-temperature cooling water; then the spraying assembly 8 is turned on, and the spraying assembly 8 sprays a coolant onto the cooling coil 5. The coolant forms droplets and drips onto the cooling coil 5 below. The coolant droplets absorb the heat of the cooling coil 5 and then drip through the gaps in the middle of the cooling coil 5; the cooling of the cooling coil 5 is completed, and at the same time, the cooling of the cooling water is also completed.

[0026] The cooled cooling water can be recycled and added to the drug extraction tank for continued use; with this equipment, a low-temperature water source can be continuously supplied to the extraction tank to participate in the cooling of drug extraction.

[0027] After the coolant droplets of this device drip from the cooling coil 5 placed in the cooling space 2, they will enter the evaporation space 3. There is nothing set in this evaporation space 3, only a lot of through grooves 15 are provided on the tower wall of the cooling tower 1 where the evaporation space 3 is located; the through grooves 15 are arranged around the cooling tower 1; at the same time, a guiding air blower 10 is also arranged outside the evaporation space 3. When the guiding air blower 10 is started, airflows will enter the evaporation space 3 of the cooling tower 1 from the other three directions, and then flow out from the direction where the guiding air blower 10 is located.

[0028] The purpose of such a setting is that due to the heat exchange space 4 in this device, a heat exchange filler 9 is arranged in the heat exchange space 4 below the evaporation space 3. When the high-temperature coolant droplets contact the heat exchange filler 9, the cooling temperature decreases, but gas is generated on the surface of the heat exchange filler 9. After the gas rises to the evaporation space 3, it will be output outside the cooling tower 1 along the direction of the guiding air blower 10.

[0029] With such a setting, it is possible to prevent high-temperature gas from rising to the cooling coil 5 in the cooling space 2 and avoid reheating the cooled cooling coil 5.

[0030] Meanwhile, with such a setting of this device, not only can the recycling of cooling water be achieved, but also the recycling of coolant can be realized. Because after the coolant is sprayed on the cooling coil 5, it will absorb the heat of the cooling water, resulting in an increase in the temperature of the coolant; and the coolant with increased temperature is obviously no longer usable; while this device is provided with a heat exchange space 4, which can absorb the heat carried by the coolant through the heat exchange packing 9, and at the same time the heat is converted into gas and blown out of the cooling tower 1 by the guiding fan 10 outside the evaporation space 3.

[0031] The spraying assembly 8 includes a spraying main pipe 81 and a number of spraying sub-pipes 82 arranged at the front and rear ends of the spraying main pipe 81, and spray nozzles 83 are arranged at the lower ends of the spraying sub-pipes 82.

[0032] The spraying area of the spraying assembly 8 of this device is determined based on the area of the cooling coil 5. Generally speaking, the cooling coil 5 will be bent into a bent pipe with a square volume; so the spraying assembly 8 needs to guide the coolant in the spraying main pipe 81 to the upper part of the cooling coil 5 through the spraying sub-pipes 82;

[0033] The through groove 15 of the evaporation space 3 is formed by an inclined air guiding plate 11, and the inclination angle of the guiding fan 10 is the same as the inclination angle of the air guiding plate 11. The purpose of the air guiding plate 11 is to guide the air flow into the evaporation space 3 at an appropriate angle, which can improve the efficiency of the air flow passing through.

[0034] A liquid collecting space 12 is also provided at the bottom of the cooling tower 1 below the heat exchange space 4, and the liquid collecting space 12 is communicated with the outside through an output pipe 13.

[0035] The function of the liquid collecting space 12 of this device is to collect the cooled coolant, and the output pipe 13 can output the coolant.

[0036] The spraying main pipe 81 is communicated with the output pipe 13, and a water pump 14 is arranged at the connection between the spraying main pipe 81 and the output pipe 13.

[0037] With such a setting, the coolant can also realize liquid circulation through the spraying main pipe 81, the output pipe 13, and the water pump 14; and can continuously cool the cooling water in the cooling tower 1.

[0038] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any person skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
