Technical Field

[0001] The utility model relates to the field of medicine cooling equipment, in particular to a medicine preparation rapid cooling equipment. Background Art

[0002] Pharmaceutical preparations refer to various dosage forms for clinical use that are made by processing drug raw materials and appropriate excipients. In the pharmaceutical industry, the production process of drug preparations has extremely strict requirements on temperature control. From the synthesis of raw materials to the molding of the final preparation, each step needs to be carried out within a specific temperature range to ensure that the active ingredients of the drug are not destroyed, while ensuring the stability and safety of the product.

[0003] With the continuous development of modern pharmaceutical technology, the production process of pharmaceutical preparations has become increasingly complex, and higher requirements have been placed on the accuracy and speed of temperature control.

[0004] Traditional cooling methods mainly include natural cooling and simple air cooling, water cooling, etc. Among them, although water cooling can cool to a certain extent, when the liquid medicine enters the water cooling box, it is usually cooled by the medicine contacting the inner wall of the water cooling box, and then the water absorbs the heat conducted by the inner wall to achieve cooling. In this process, the medicine attached to the inner wall of the water cooling box has relatively good heat conduction efficiency due to direct contact with the inner wall, and can be cooled faster. However, the medicine in the middle position and not in contact with the inner wall can only be cooled by slow conduction of the surrounding medicine and heat exchange with the surrounding environment, resulting in large differences in the cooling speed of the medicine at different positions, resulting in uneven cooling efficiency and poor cooling effect. Therefore, a rapid cooling device for drug preparations is proposed to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a rapid cooling device for pharmaceutical preparations, the purpose of which is to improve the problem in the prior art that "during water cooling, the cooling speed of liquid medicine at different positions in the cooling box is different, resulting in uneven cooling efficiency and low cooling effect."

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a rapid cooling device for pharmaceutical preparations, which includes a water cooling box, a medicine inlet pipe is fixedly installed on the upper left part of the water cooling box, a liquid outlet pipe is fixedly installed on the lower right part of the water cooling box, a cooling cylinder is provided on the inner wall of the water cooling box, a medicine outlet pipe is fixedly connected to the lower front surface of the cooling cylinder, the medicine outlet pipe passes through the water cooling box and is connected to the cooling cylinder, a liquid inlet pipe is fixedly installed on the upper rear surface of the water cooling box, a spray assembly is provided on the inner wall of the cooling cylinder, the spray assembly includes a storage disk, a connecting pipe is fixedly connected to the top of the storage disk, the connecting pipe is rotatably connected to the inner wall of the water cooling box near the top of the cooling cylinder, and a connecting groove is provided on the inner wall of the water cooling box near the top of the connecting pipe.

[0008] Preferably, the inner wall of the connecting tube is fixedly connected to a support frame, and the top end of the support frame is fixedly connected to a rotating rod.

[0009] Preferably, a servo motor is fixedly mounted on the top of the water cooling box, and the bottom end of the output shaft of the servo motor is fixedly connected to the top end of the rotating rod.

[0010] Preferably, the outer wall of the storage disk is fixedly connected with a drug guide head and multiple groups are provided.

By setting a guide column and a spiral guide vane, when the liquid medicine is sprayed on the inner wall of the cooling cylinder and flows downward, the guide column and the guide vane cooperate, so that the liquid medicine can always contact the inner wall of the cooling cylinder when it is transferred downward on the guide vane, so that it can always exchange heat with the water outside the cooling cylinder and inside the guide column, thereby further improving the cooling effect and further improving the cooling efficiency.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1 、 Figure 2 and Figure 3 As shown, an embodiment of the present invention is provided: a drug preparation rapid cooling device, including a water cooling box 1 that can cool liquid drugs. The water cooling box 1 serves as the main body of the entire cooling system and provides an environment for cooling liquid drugs. A drug inlet pipe 2 for adding liquid drugs is fixedly installed on the upper left side of the water cooling box 1. The drug inlet pipe 2 is used to add liquid drugs to be cooled. A liquid outlet pipe 4 for circulating cooling water is fixedly installed on the lower right side of the water cooling box 1. The inner wall of the water cooling box 1 is provided with a cooling cylinder 35 that can store liquid drugs in the cooling cylinder 35 and exchange heat with cooling water outside the cooling cylinder 35 for cooling. The lower front surface of the cooling cylinder 35 is fixedly connected to a drug outlet pipe 5 that can transmit the cooled liquid drugs.

[0022] The medicine outlet pipe 5 outputs the cooled liquid medicine, and the medicine outlet pipe 5 passes through the water-cooling box 1 and is connected with the cooling cylinder 35, and the cooled medicine can be transmitted out through the medicine outlet pipe 5. A liquid inlet pipe 7 for adding cooling water to the outside of the cooling cylinder 35 in the water-cooling box 1 is fixedly installed on the upper part of the rear surface of the water-cooling box 1. The liquid inlet pipe 7 and the liquid outlet pipe 4 are respectively responsible for adding cooling water into the water-cooling box 1 and discharging the cooling water after use, so as to realize the circulation and renewal of the cooling water. The liquid inlet pipe 7 is connected with the inner wall of the water-cooling box 1, and the inner wall of the cooling cylinder 35 is provided with a spraying assembly, which includes a storage disk 34 for temporarily storing the medicine added from the medicine inlet pipe 2. The top of the storage disk 34 is fixedly connected with a connecting pipe 33 for transmitting the medicine into the storage disk 34. The connecting pipe 33 is rotatably connected to the inner wall of the water-cooling box 1 near the top of the cooling cylinder 35. The inner wall of the water-cooling box 1 is provided with a connecting groove 37 near the top of the connecting pipe 33, which can transmit the medicine added from the medicine inlet pipe 2 to the connecting pipe 33.

[0023] like Figure 2 、 Figure 3 and Figure 4 As shown, the inner wall of the cooling cylinder 35 is provided with a guide assembly, which includes a guide column 6 that can guide the liquid medicine to both sides to contact the cooling cylinder 35 for heat exchange and cooling. The guide column 6 is fixedly connected to the bottom end of the inner wall of the cooling cylinder 35. The outer wall of the guide column 6 is fixedly connected with a guide vane 62 that can guide the liquid medicine to contact the inner wall of the cooling cylinder 35 and the outer wall of the guide column 6 to improve the cooling effect. The guide vane 62 is fixedly connected to the inner wall of the cooling cylinder 35.

[0024] like Figure 1 、 Figure 2 and Figure 3 As shown, the inner wall of the connecting pipe 33 is fixedly connected to a support frame 32 that drives the connecting pipe 33 to rotate, and the top of the support frame 32 is fixedly connected to a rotating rod 31 that drives the support frame 32 to rotate. The top of the water cooling box 1 is fixedly installed with a servo motor 3 that drives the rotating rod 31 to rotate. The servo motor 3 is an existing structure and can be implemented by technicians in this field. Since it is an existing technology, it will not be described in detail in this case. The bottom end of the output shaft of the servo motor 3 is fixedly connected to the top of the rotating rod 31, and the outer wall of the storage disk 34 is fixedly connected to a drug guide head 36 and is provided with multiple groups. The multiple groups of drug guide heads 36 are evenly arranged on the outer wall of the storage disk 34. By setting multiple groups of drug guide heads 36 and coordinating the rotation of the drug guide heads 36, the liquid medicine can be evenly sprayed on the inner wall of the cooling cylinder 35, thereby improving the heat exchange effect and quickly cooling the liquid medicine, thereby improving the cooling efficiency. The storage disk 34, the drug guide head 36, and the connecting pipe 33 are all arranged on the inner wall of the cooling cylinder 35.

[0025] like Figure 2 、 Figure 3 and Figure 4As shown, the guide blade 62 is set to a spiral shape. By setting the guide blade 62 to a spiral shape, the liquid medicine can be transferred downward along the spiral guide blade 62, so that when being transferred on the guide blade 62, it can stick to the outer wall of the guide column 6 and the inner wall of the cooling cylinder 35, so that heat exchange can be carried out quickly, further improving the cooling effect of the liquid medicine. The guide column 6 is set to a flat-top cone shape. By setting it to a flat-top cone shape, the liquid medicine can be guided to both sides of the guide column 6 to contact the inner wall of the cooling cylinder 35, thereby improving the cooling effect. A circulation pipe 1 61 is fixedly connected to the upper front surface of the guide column 6 and can cooperate with the circulation pipe 2 63 to allow the cooling water to circulate. The circulation pipe 1 61 passes through the cooling cylinder 35 and is connected to the inner wall of the water-cooling box 1. A circulation pipe 2 63 is fixedly connected to the lower rear surface of the guide column 6 and can cooperate with the circulation pipe 1 61 to allow the cooling water to circulate. The circulation pipe 2 63 passes through the cooling cylinder 35 and is connected to the inner wall of the water-cooling box 1. The cooling water can circulate through the cooperation of the circulation pipe 1 61 and the circulation pipe 2 63, thereby further improving the cooling effect.

[0026] The working principle of the present invention is as follows: when in use, when the liquid medicine is added into the water cooling box 1 from the medicine inlet pipe 2, the medicine first enters the connecting groove 37, and the connecting groove 37 plays a transition role, guiding the medicine into the connecting pipe 33. The connecting pipe 33 rotates under the drive of the support frame 32, the rotating rod 31 and the servo motor 3, and the medicine is transferred from the inner wall of the connecting pipe 33 to the storage disk 34. The outer wall of the storage disk 34 is fixed with multiple groups of medicine guide heads 36. The rotation of the servo motor 3 drives the rotating rod 31, the support frame 32, the connecting pipe 33, the storage disk 34 and the medicine guide heads 36 to rotate. Through the multiple groups of medicine guide heads 36, the liquid medicine can be evenly sprayed onto the inner wall of the cooling cylinder 35, so that the liquid medicine is fully in contact with the inner wall of the cooling cylinder 35, so that the medicine can be evenly and faster to exchange heat with the water outside the cooling cylinder 35, thereby improving the effect of heat exchange, achieving rapid cooling of the liquid medicine, and improving the cooling efficiency.

[0027] In the cooling cylinder 35, the guide column 6 is set to a flat-top cone shape, which can guide the liquid medicine to both sides so that it contacts the inner wall of the cooling cylinder 35. The guide blade 62 is set to a spiral shape. When the liquid medicine is transmitted downward along the spiral guide blade 62, it will stick to the outer wall of the guide column 6 and the inner wall of the cooling cylinder 35, further increasing the contact area between the medicine and the cooling environment, thereby better performing heat exchange and improving the cooling effect of the liquid medicine.

[0028] At the same time, the circulation pipe 1 61 and the circulation pipe 2 63 on the guide column 6 are connected to the water cooling box 1, and are connected to the liquid inlet pipe 7 and the liquid outlet pipe 4, so that the cooling water can be connected to the outside for circulation, thereby further improving the cooling effect and ensuring that the medicine can reach the required cooling temperature in a shorter time.
