Description

Technical Field

[0001] This utility model relates to the field of sartan biphenyl, and in particular to a circulating drying device for sartan biphenyl. Background Technology

[0002] Sartan biphenyl is a pharmaceutical intermediate used to synthesize novel sartan antihypertensive drugs, such as losartan, valsartan, iprosartan, and irbesartan.

[0003] A search revealed that the Chinese patent "A Vacuum Drying Device for the Synthesis of the Pharmaceutical Intermediate Sartan-Biphenyl" (CN216716823U) discloses a vacuum drying device for the synthesis of the pharmaceutical intermediate sartan-biphenyl. The device includes a housing with a drying chamber inside. Inside the drying chamber, placement plates are equidistantly arranged vertically via sliding rails. A slot is located at the center of the outer wall of each placement plate, and a pull-out box containing a desiccant is inserted into the slot. This device effectively dries the air inside the drying chamber, significantly improving its drying efficiency. The pull-out box, inserted into the slot, has a locating block that slides along a positioning groove, enhancing stability during removal and facilitating desiccant replacement. Heating tubes are arranged around the drying chamber near the housing, greatly increasing the dryness of the chamber. The serpentine arrangement of the heating tubes further improves the uniformity of drying within the chamber.

[0004] Although the aforementioned drying equipment can achieve a certain drying effect through the combination of desiccant and electric heating tubes, the multiple stacked placement plates for storing sartan biphenyl make it difficult for the sartan biphenyl in the middle to receive uniform heat due to the use of two electric heating tubes for simultaneous heating from above and below. Furthermore, since the heat energy cannot be recovered and reused, there will be a problem of resource waste.

[0005] Therefore, a circulating dryer for sartan-biphenyl is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a circulating drying device for sartan biphenyl to solve the above-mentioned problems, thereby improving the problems of traditional drying equipment that cannot recover heat energy and has low drying efficiency.

[0007] This utility model achieves the above objectives through the following technical solution, and is used in a sartan biphenyl circulating drying equipment, comprising: a drying equipment body;

[0008] The drying equipment body mainly consists of a main body and a storage component;

[0009] The main component includes a housing;

[0010] The storage unit includes a housing disposed in a box, the upper part of the housing is a sartan biphenyl placement part, and the middle and lower part of the housing is provided with a storage shell;

[0011] A circulation component capable of recovering heat energy and continuously heating to promote drying effect is provided in the housing;

[0012] The circulation component includes a guide shell connected to the top of the housing. The top of the guide shell is connected to an air duct, and a fan is installed in the air duct. When the lower end of the air duct is configured as a double-pipe, the lower end of the air duct passes through the main body and is connected to the circulation shell. The air outlets of the two circulation shells are connected to guide pipes, and the air outlets of the guide pipes are connected to the guide shell.

[0013] Preferably, the main component further includes an electric heating tube, which is located in the lower middle part of the chamber. The electric heating tube can heat the gas in the chamber, thereby improving the drying effect on the sartan biphenyl powder.

[0014] Preferably, the storage component further includes a guide rail and a slide. The guide rail is fixedly connected to the lower middle part of the housing, and the slide is disposed in the guide rail. The side of the slide closest to the storage housing is fixedly connected to the storage housing. The guide rail and the slide can limit the position of the storage housing, which is convenient for the staff to replace the desiccant later.

[0015] Preferably, two circulation shells are provided, and the two circulation shells are respectively fixedly connected to the two sides of the inner wall of the box. As described above, the airflow can be guided from the side of the inner cavity of the box to prevent the airflow from causing the sartan biphenyl powder to disperse.

[0016] Preferably, the top and bottom of the circulation shell surface are provided with through holes, the middle part of the circulation shell is hollow, and the hollow part of the circulation shell communicates with the through holes.

[0017] Preferably, the ports of both through holes are elliptical in shape, and the two through holes are oriented in opposite directions. As described above, this facilitates the guidance of gas.

[0018] Preferably, a guide plate is provided at the lower through-hole port, and the guide plate faces upward.

[0019] The beneficial effects of this utility model are:

[0020] The circulation component heats the chamber through the heating element. This works in conjunction with the desiccant in the storage shell to remove moisture from the sartan biphenyl. The airflow is guided from the bottom up from both sides of the chamber cavity to adsorb the still warm airflow and re-inject it into the chamber for heating. This process is repeated to significantly increase the temperature of the airflow, improve the drying effect of sartan biphenyl, and also achieve the effect of resource utilization.

[0021] By placing two circulation shells on both sides of the inner cavity of the chamber, the moisture of sartan biphenyl and the desiccant in the storage shell can be guided from the side when the airflow blows from bottom to top. This can effectively prevent the airflow from interfering with the sartan biphenyl and causing the sartan biphenyl powder to scatter. At the same time, by using the above-mentioned method of moisture treatment, the amount of moisture removed from each layer can be kept consistent when drying sartan biphenyl in layers, thereby improving the drying uniformity of sartan biphenyl.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] In practical implementation: such as Figure 1-5As shown, a circulating drying device for sartan biphenyl includes: a drying device body 1; the drying device body 1 mainly consists of a main body 11 and a storage component 13; the main body 11 includes a housing 111; the main body 11 also includes an electric heating tube 112, which is disposed in the lower middle part of the housing 111; the storage component 13 includes a shell 131 disposed in the housing 111, the upper part of the shell 131 is a sartan biphenyl placement part, and the lower middle part of the shell 131 is provided with a storage shell 133; a circulation component 12 capable of recovering heat energy and continuously heating to promote the drying effect, the circulation component 12 is disposed in the housing 111; the storage component 13 also includes a guide rail 132 and a slide 134, the guide rail 132 is fixedly connected to the lower middle part of the shell 131, the slide 134 is disposed in the guide rail 132, and the side of the slide 134 near the storage shell 133 is fixedly connected to the storage shell 133.

[0030] Sartan biphenyl is a pharmaceutical intermediate that is a colorless crystal that turns dark when exposed to light. This indicates that it may undergo chemical changes in a humid environment, affecting its stability and purity. Therefore, it needs to be dried using the aforementioned drying equipment body 1.

[0031] It should be noted that sartan biphenyl is toxic and has a significant sensitizing effect on the skin. Therefore, it is necessary to ensure that it is dry during handling to reduce the chance of contact with moisture and thus reduce the risk.

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, the circulation assembly 12 includes a guide shell 121 connected to the top of the housing 111. A duct 122 is connected to the top of the guide shell 121. A fan 123 is installed in the duct 122. When the lower end of the duct 122 is configured as a double-pipe, the lower end of the duct 122 extends through the main body 11 and is connected to a circulation shell 124. The air outlets of both circulation shells 124 are connected to guide pipes 127, and the air outlets of the guide pipes 127 are connected to the guide shell 121. The circulation shell 124 is configured with... There are two circulation shells 124, which are fixedly connected to the two sides of the inner wall of the housing 111 respectively. The top and bottom of the surface of the circulation shell 124 are provided with through holes 125. The middle part of the circulation shell 124 is hollow and communicates with the through holes 125. The ports of the two through holes 125 are both elliptical and the two through holes 125 are oriented in opposite directions. The port of the lower through hole 125 is provided with a guide plate 126, which is oriented upward.

[0033] First, the heating element 112 is turned on to raise the temperature in the chamber 111. Combined with a desiccant, this adsorbs and removes moisture from the sartan biphenyl. Then, the fan 123, through the guide shell 121, injects the airflow from the chamber 111 into the two circulation shells 124 via the air duct 122. The gas is initially discharged through the lower through-hole 125 of the circulation shell 124. The airflow then flows upwards through the guide plate 126. As the gas flows, it passes the side of the outer shell, blowing upwards the moisture from the sartan biphenyl, the moisture adsorbed by the desiccant, and the airflow heated by the heating element 112. This mixture then re-enters the guide shell 121 through the upper through-hole 125 and the guide pipe 127. This process is repeated, not only treating the moisture in the chamber 111 but also raising the temperature as the airflow passes repeatedly through the heating element 112, effectively promoting the drying of the sartan biphenyl powder.

[0034] In use, when workers need to dry sartan biphenyl, a desiccant is first placed in the storage shell 133, and then the sartan biphenyl is placed in the upper middle part of the shell 131. The door is then closed, creating a sealed space within the chamber 111. The heating element 112 is then turned on to raise the temperature within the chamber 111. Combined with the desiccant, this allows the moisture in the sartan biphenyl to be adsorbed and removed. At this point, the fan 123 is turned on, and the fan 123 guides the airflow from the chamber 111 through the guide shell 121 into the two circulation shells 124 via the air duct 122. The gas will first pass through... The airflow is discharged outward through the lower through-hole 125 of the circulation shell 124. At this time, the airflow will flow upward through the guide plate 126. When the gas flows, it will pass through the side of the shell, which can blow the moisture of sartan biphenyl, the moisture adsorbed by the desiccant, and the airflow heated by the electric heating tube 112 upward together. Then, it will enter the guide shell 121 again through the upper through-hole 125 and the guide tube 127. This process is repeated. The moisture in the chamber 111 is not only treated, but the temperature is also increased as the airflow is repeatedly heated by the electric heating tube 112, which can effectively promote the drying of sartan biphenyl powder.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
