Description

Technical Field

[0001] The utility model belongs to the technical field of drug production equipment and relates to an intelligent dehumidification box, in particular to an intelligent dehumidification box for the production of Musk Heart Pills. Background Art

[0002] In the existing production of Musk Heart Pills, the pills need to be dehumidified, and a dehumidification box is conventionally used for cooling and dehumidification. The dehumidification box uses a surface cooler to cool and dehumidify. Its principle is to reduce the air temperature so that the relative humidity of the air is greater than 100%, and the moisture will be precipitated and discharged from the air. However, the mainstream equipment of the existing dehumidification box is a rotary dehumidifier. Due to the low dehumidification humidity and fast dehumidification, the surface of the pills may be oily, affecting the quality.

[0003] At the same time, the medium used in the surface cooler of the existing dehumidification box is refrigerant. If the refrigerant is directly used for cooling, the surface cooler will frost and it will take a long time to defrost. Otherwise, severe icing will occur, resulting in a decrease in the dehumidification effect, affecting humidity control, and further affecting the problem of continuous and stable dehumidification of the equipment. Especially in the plum rain and high temperature seasons, the humidity of the box will be around 30% for a long time. Once the ambient temperature and humidity change, the humidity will exceed the limit, the drying time will be extended, and the moisture content in the pills will be close to the upper limit, affecting the quality of the pills.

[0090] Combine the following Figure 1 , describing the specific use process of an intelligent dehumidification box in the utility model.

[0091] When the operator uses the intelligent dehumidification box, the strong current cabinet 22 is started to provide power to the chiller 3, the surface cooler 5, the heater 6, the motor 7, the return air valve 12, the fresh air valve 13, and the chilled water valve group 14. The pills are placed in the dehumidification box 1, and a start signal is sent to the chiller 3, the surface cooler 5, the heater 6, the motor 7, the return air valve 12, the fresh air valve 13, and the chilled water valve group 14 through the controller in the weak current cabinet 23. The chiller 3, the surface cooler 5, the heater 6, the motor 7, the return air valve 12, the fresh air valve 13, the first stop valve 141, the second stop valve 142, the third stop valve 143, and the three-way valve 145 in the chilled water valve group 14 are started and opened after receiving the signal. Water is used as the medium, and the chilled water prepared by the chiller 3 is sent to the surface cooler 5 after being filtered through the chilled water supply pipe 19 and the Y-type filter 15. The pills in the dehumidifying box 1 dissipate moisture to the air in the dehumidifying box 1, and the humid air enters the air through the return air port 11 and the return air pipe 18. In the air conditioning box 2, after being filtered by the primary filter 4 and contacting the surface cooler 5, the air reaches the dew point temperature, so that the relative humidity of the air reaches 100%, so that the moisture is precipitated and discharged from the air, and the moisture content of the air is reduced. The electric heating of the heater 6 after the surface cooler 5 heats the air, thereby reducing the relative humidity of the air. Then, the fan 8 driven by the motor 7 makes the air filtered by the medium efficiency filter 9, and then sent into the dehumidification box 1 through the air supply duct 17, so that the air in the dehumidification box 1 can meet the temperature and humidity requirements required for production. Through the above-mentioned air circulation process in the dehumidification box 1, the pills in the dehumidification box 1 are continuously dried.

[0092] After use, the controller in the weak current cabinet 23 sends a closing signal to the chiller 3, the surface cooler 5, the heater 6, the motor 7, the return air valve 12, the fresh air valve 13, and the chilled water valve group 14. The chiller 3, the surface cooler 5, the heater 6, the motor 7, the return air valve 12, the fresh air valve 13, the first stop valve 141, the second stop valve 142, the third stop valve 143, and the three-way valve 145 are closed after receiving the signal. If necessary, fresh air is introduced from the outside of the dehumidification box 1 through the fresh air duct 16 to ensure a slight positive pressure in the dehumidification box 1, so that the air supply duct 17 and the return air duct 18 form an air supply circulation loop. Water is also replenished to the chiller 3 through the chilled water replenishment pipe 21 via the tap water pipe.

[0093] In addition, according to the change of the box temperature, the controller in the weak current cabinet 23 sends a start signal to the fourth stop valve 144 in the chilled water valve group 14. The fourth stop valve 144 starts to open after receiving the signal, thereby regulating the chilled water flow and bypass flow entering the air conditioning box 2 through the chilled water bypass pipe 146.

[0094] In summary, the utility model provides an intelligent dehumidification box that provides a purified environment that meets the requirements of pharmaceutical production, and can avoid frosting of the equipment during long-term operation, stabilize the temperature and humidity, and ensure the drying effect and quality of the pills. The above embodiments only illustrate the principle and efficacy of the utility model, and are not intended to limit the utility model. Anyone familiar with this technology can modify or change the above embodiments without violating the spirit and scope of the utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in the utility model should still be covered by the claims of the utility model.
