[0002] In the production of some pharmaceuticals, excipients are often required. Besides acting as excipients, carriers, and improving stability, pharmaceutical excipients also play a crucial role in forming the drug release system, protecting, supporting, and enhancing drug safety, improving bioavailability, and increasing patient compliance. Most excipients require heating or drying processes before being added to the production process.

[0003] According to the publication number (CN221915690U), a preheating tank for the production of pharmaceutical excipients is disclosed, including a placement box. A box cover is provided on the top of the placement box. A drive motor is fixed to the top side wall of the box cover. The output shaft of the drive motor is fixed to a connecting shaft through a coupling. The end of the connecting shaft away from the drive motor passes through the box cover and is fixed with symmetrically distributed preheating plates. Heating wires are provided inside the preheating plates. A heating tube is embedded in the bottom side wall of the box cover.

[0004] The technical solution has at least the following drawbacks: although the invention can preheat pharmaceutical excipients, it is inconvenient to discharge the excipients after preheating and it is also inconvenient to position the opened cover. Therefore, improvements are urgently needed. Thus, we propose a preheating tank for pharmaceutical excipient production. Utility Model Content

[0005] The purpose of this utility model is to provide a preheating tank for the production of pharmaceutical excipients, which solves the problems mentioned in the background art, namely, that it is inconvenient to discharge the pharmaceutical excipients after each preheating and that it is inconvenient to position the opened cover.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a preheating tank for pharmaceutical excipient production, comprising a support frame, a preheating tank detachably mounted on the upper end of the support frame, a cover plate provided on the upper end of the preheating tank, a stirring motor fixedly mounted on the upper end of the cover plate, a feeding channel connected to the lower end of the preheating tank, a sealing component for blocking the feeding channel provided on one side of the preheating tank, and a limiting component for supporting and limiting the stirring motor provided on one side of the cover plate.

[0007] Optionally, the sealing assembly includes a fixed plate disposed on the left side of the preheating tank. Fixed rods are welded to the front and rear sides of the upper end of the fixed plate. Fixed strips are welded to the front and rear sides of the cover plate. A slot is provided at the lower end of the fixed strip. A return spring is fixedly installed on the inner side of the fixed plate. The other end of the return spring is fixedly connected to the outer side of the preheating tank. Two return springs are provided. A baffle is fixedly installed at the lower end of the fixed plate. The baffle is movably connected to the support frame.

[0008] Optionally, the limiting component includes a limiting rod disposed above the cover plate. The limiting rod is fixedly connected to the cover plate by welding. Two limiting rods are provided. One end of the limiting rod is provided with a limiting groove. The lower end of the limiting rod is movably connected to the limiting groove. A fixing ring is welded to the other side of the preheating tank. An insert rod is welded to the other side of the cover plate. The insert rod is movably connected to the fixing ring.

[0009] Optionally, the size of the fixing rod is adapted to the size of the slot, and the fixing rod is movably connected to the slot.

[0010] Optionally, the stirring motor is located inside the preheating tank, and the inner wall of the preheating tank is provided with heating wires for preheating the auxiliary materials.

[0011] Optionally, a guide plate is welded to the lower end of the support frame, and the guide plate is located below the material unloading channel.

[0012] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0013] The technical solution of this application, through the setting of a support frame, preheating tank, stirring motor, limit rod, return spring, limit groove and insert rod, can pull the fixed plate to move to the left, and at the same time stretch the return spring, so that the fixed plate drives the baffle to separate from the discharge channel, thereby facilitating the discharge of the preheated pharmaceutical excipients through the discharge channel. This avoids the situation where pharmaceutical excipients get stuck in the valve when using valve control, and also saves the trouble of workers tilting the preheating tank to pour out the pharmaceutical excipients.

[0014] At the same time, during the process of pulling the fixed plate, the fixed plate will cause the fixed rod and the fixed strip to separate, which makes it easier to pull the cover plate upward, eliminating the trouble of using buckles to restrict the cover plate.

[0015] After the fixing rod separates from the fixing bar, the cover plate can drive the stirring motor and stirring rod to separate from the preheating tank, thus facilitating the discharge of pharmaceutical excipients from the discharge channel. At the same time, as the cover plate moves upward, the limiting rod on the cover plate will be engaged in the limiting groove. At this time, the fixing plate is pulled to the left, thereby engaging the lower end of the limiting rod in the limiting groove, thus limiting the position of the cover plate. This makes it convenient for staff to add new pharmaceutical excipients to the preheating tank after the pharmaceutical excipients are discharged. Attached Figure Description

[0021] Please see Figure 1-3 This utility model provides a technical solution: a preheating tank for pharmaceutical excipient production, including a support frame 1, a preheating tank 11 detachably mounted on the upper end of the support frame 1, a cover plate 12 provided on the upper end of the preheating tank 11, a stirring motor 13 fixedly mounted on the upper end of the cover plate 12, a feeding channel 14 connected to the lower end of the preheating tank 11, a sealing component for blocking the feeding channel 14 provided on one side of the preheating tank 11, and a limiting component for supporting and limiting the stirring motor 13 provided on one side of the cover plate 12.

[0022] In this embodiment, the pharmaceutical excipients are preheated by the heating wire inside the preheating tank 11, while the stirring motor 13 is turned on to slowly stir the pharmaceutical excipients in the preheating tank 11, thereby ensuring the preheating effect of the pharmaceutical excipients. After preheating is completed, the preheated pharmaceutical excipients can be quickly discharged by opening the sealing component, saving the trouble of pouring and discharging by the staff. Moreover, the setting of the limiting component can support and limit the stirring motor 13, thereby facilitating the separation of the cover plate 12 from the preheating tank 11, and thus facilitating the addition of pharmaceutical excipients.

[0023] In this technical solution, the sealing assembly includes a fixing plate 2 located on the left side of the preheating tank 11. Fixing rods 21 are welded to both the front and rear sides of the upper end of the fixing plate 2. Fixing strips 22 are welded to both the front and rear sides of the cover plate 12. A slot 23 is provided at the lower end of the fixing strip 22. A return spring 24 is fixedly installed on the inner side of the fixing plate 2. The other end of the return spring 24 is fixedly connected to the outer side of the preheating tank 11. Two return springs 24 are provided. A baffle 25 is fixedly installed at the lower end of the fixing plate 2. The baffle 25 is movably connected to the support frame 1.

[0024] In this embodiment, after the pharmaceutical excipients are preheated, the fixed plate 2 is pulled to the left, and at the same time the return spring 24 is stretched, so that the fixed plate 2 drives the baffle 25 to separate from the discharge channel 14, thereby facilitating the discharge of the preheated pharmaceutical excipients through the discharge channel 14. This avoids the situation where the pharmaceutical excipients get stuck in the valve when using a valve for control, and also saves the trouble of the staff tilting the preheating tank 11 to pour out the pharmaceutical excipients. At the same time, during the process of pulling the fixed plate 2, the fixed plate 2 will drive the fixed rod 21 to separate from the fixed strip 22, thereby facilitating the upward movement of the cover plate 12, saving the trouble of using a buckle to limit the cover plate 12.

[0025] In this technical solution, the limiting component includes a limiting rod 3 disposed above the cover plate 12. The limiting rod 3 is fixedly connected to the cover plate 12 by welding. There are two limiting rods 3. One end of the limiting rod 3 is provided with a limiting groove 31. The lower end of the limiting rod 3 is movably connected to the limiting groove 31. A fixing ring 32 is welded to the other side of the preheating tank 11. An insert rod 33 is welded to the other side of the cover plate 12. The insert rod 33 is movably connected to the fixing ring 32.

[0026] In this embodiment, after the fixing rod 21 separates from the fixing strip 22, the cover plate 12 can be pulled upward to separate the cover plate 12 from the stirring motor 13 and the stirring rod, thus facilitating the discharge of pharmaceutical excipients from the discharge channel 14. At the same time, during the upward movement of the cover plate 12, the limiting rod 3 on the cover plate 12 will be engaged in the limiting groove 31. At this time, the fixing plate 2 is pulled to the left to engage the lower end of the limiting rod 3 in the limiting groove 31, thereby limiting the position of the cover plate 12. This facilitates the addition of new pharmaceutical excipients to the preheating tank 11 after the pharmaceutical excipients are discharged.

[0027] In this technical solution, the size of the fixing rod 21 is adapted to the size of the slot 23, and the fixing rod 21 is movably connected to the slot 23.

[0028] In this embodiment, the fixed rod 21 cooperates with the slot 23 to position the cover plate 12, thereby facilitating the limitation of the cover plate 12.

[0029] In this technical solution, the stirring motor 13 is located inside the preheating tank 11, and the inner wall of the preheating tank 11 is provided with heating wires for preheating the auxiliary materials.

[0030] In this embodiment, the heating wire installed inside the preheating tank 11 facilitates the heating of the pharmaceutical excipients, and the stirring motor 13 on the preheating tank 11 facilitates the stirring of the heated pharmaceutical excipients inside the preheating tank 11, thereby ensuring the preheating effect of the pharmaceutical excipients.

[0031] In this technical solution, a guide plate 26 is welded to the lower end of the support frame 1, and the guide plate 26 is located below the material feeding channel 14.

[0032] In this embodiment, the guide plate 26 is provided to guide the pharmaceutical excipients discharged from the feeding channel 14, thereby facilitating the discharge and guidance of the preheated pharmaceutical excipients.

[0033] During use, the pharmaceutical excipients are preheated by the heating wire inside the preheating tank 11. Simultaneously, the stirring motor 13 is turned on to slowly agitate the excipients within the preheating tank 11, ensuring effective preheating. Once preheating is complete, the fixing plate 2 is pulled to the left, simultaneously stretching the return spring 24. This causes the fixing plate 2 to separate the baffle 25 from the discharge channel 14, facilitating the discharge of the preheated excipients through the discharge channel 14. This avoids the problem of excipients getting stuck in valves, which is a common issue with valve control, and eliminates the need for workers to tilt the preheating tank 11 to pour the excipients. During the pulling process, the fixing plate 2 also moves the fixing rod 21 to the fixing... The strip 22 separates, making it easier to pull the cover plate 12 upward, eliminating the hassle of using clips to limit the cover plate 12. After the fixing rod 21 separates from the fixing strip 22, the cover plate 12 can be pulled upward again, causing the cover plate 12 to drive the stirring motor 13 and stirring rod to separate from the preheating tank 11, thus facilitating the discharge of pharmaceutical excipients from the discharge channel 14. At the same time, during the upward movement of the cover plate 12, the limiting rod 3 on the cover plate 12 will be engaged in the limiting groove 31. At this time, the fixing plate 2 is pulled to the left, thus engaging the lower end of the limiting rod 3 in the limiting groove 31, thereby limiting the position of the cover plate 12. This makes it convenient for staff to add new pharmaceutical excipients to the preheating tank 11 after the pharmaceutical excipients are discharged.
