Description

Technical Field

[0001] This utility model relates to a closed material discharge device and a material transfer system, belonging to the field of material transfer technology. Background Technology

[0002] In the pharmaceutical and health product industries, powders typically require initial mixing using an airflow mixer. After homogenization within the mixer, the powders need to be transferred to other equipment for further processing. Currently, a reusable hopper is used to handle this mixing process. The hopper is pushed or moved below the outlet of the corresponding airflow mixer, which then discharges the mixed material into the hopper. After the hopper is empty, it is removed. To facilitate the turnover of the mixed materials, the hopper requires a reusable hopper during material discharge. The transfer hopper is located below the discharge port of the airflow mixer. To facilitate the connection between the transfer hopper and the discharge port and ensure that the material falls into the transfer hopper, the inlet diameter of the transfer hopper is larger than the outlet diameter of the airflow mixer. There is a certain gap between the opening of the transfer hopper and the outlet of the airflow mixer. When the airflow mixer discharges material, some powder may be exposed or leaked out through this gap. During the material discharge process, dust flies around, which not only wastes the mixed material, but also affects the working environment of the workshop and poses certain safety risks. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a closed material discharge device and a material transfer system.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A material closed discharge device includes a docking flange, a material barrel cover, a connecting pipe, and a lifting mechanism for driving the material barrel cover to move up and down. The docking flange is used to connect with the discharge pipe of the airflow mixer. The material barrel cover is adapted to the opening of the turnover material barrel. The material barrel cover is equipped with a breather. The connecting pipe is a flexible hose. The upper end of the connecting pipe is connected to the docking flange, and the lower end of the connecting pipe is connected to the material barrel cover. Under the action of the lifting mechanism, the material barrel cover moves downward to cover the turnover material barrel. The material from the airflow mixer can enter the turnover material barrel through its discharge port and the connecting pipe for closed discharge. Under the action of the lifting mechanism, the material barrel cover can move upward to detach from the turnover material barrel. The turnover material barrel can transfer the received material.

[0005] The beneficial effects of this utility model are as follows: The sealed material discharge device is installed on the housing at the discharge port of the airflow mixer. The connecting pipe is connected to the discharge port of the airflow mixer. When the airflow mixer is not discharging, the lifting mechanism does not need to operate. When the material in the airflow mixer needs to be discharged, the turnover hopper moves into position, the lifting mechanism operates, the hopper cover moves down and covers the turnover hopper, and the upper connecting flange connects to the airflow mixer. The material in the airflow mixer can directly enter the connecting pipe through the discharge port of the airflow mixer and then fall into the turnover hopper. After the material is discharged, the lifting mechanism resets, the hopper cover moves up and detaches from the turnover hopper, and the turnover hopper can be moved, thereby realizing the transfer of material. The cooperation of the connecting flange, hopper cover, connecting pipe and lifting mechanism realizes the sealed treatment of the material in the airflow mixer during the discharge process, effectively avoiding the problem of powder being exposed or leaking from the gaps, reducing material waste, improving the working environment of the workshop, and reducing safety risks. In addition, the device has a simple structure and is easy to operate. It can select the appropriate bucket lid for docking according to the bucket opening size of different turnover buckets, and is suitable for turnover buckets of various specifications, thus improving the efficiency and flexibility of material transfer.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the lifting mechanism includes at least one lifting cylinder, which is disposed between the docking flange and the hopper cover.

[0008] The beneficial effects of adopting the above-mentioned further solution are that the appropriate number of lifting cylinders can be selected according to the actual driving needs, so as to be able to smoothly drive the material bucket cover to move up and down. The lifting mechanism can adopt lifting cylinders, which realizes the smooth lifting of the material bucket cover. The lifting mechanism has a simple structure, automatic lifting, stable and reliable performance, and ensures the smooth progress of the material sealing discharge process. At the same time, the lifting cylinders are easy to maintain and replace, further improving the service life and operating efficiency of the entire device.

[0009] Furthermore, a drive bearing plate is provided on the docking flange, and the lifting cylinder is connected to the docking flange through the drive bearing plate.

[0010] The advantages of adopting the above-mentioned further solution are that, in order to meet the layout space requirements of the lifting mechanism, the installation position of the lifting mechanism can be expanded by driving the support plate, so that the distance between the lifting mechanism and the connecting pipe is maintained, the lifting cylinder can be more stably installed on the docking flange, and at the same time, the purpose of smoothly driving the material bucket cover can be met, thus improving the stability and reliability of the lifting mechanism. In addition, the setting of the drive support plate also facilitates the maintenance of the lifting cylinder.

[0011] Furthermore, the material bucket cover is provided with a connecting frame, and the lifting cylinder is connected to the material bucket cover through the connecting frame.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the connecting frame has a U-shaped structure. The open end of the U-shaped structure is connected to the top of the material bucket cover, and the closed end of the U-shaped structure is connected to the drive end of the lifting mechanism. Not only is the connection with the lifting mechanism convenient, but when dealing with turnover material buckets of different specifications, the corresponding material bucket cover can be replaced according to the size of the bucket opening, which facilitates the disassembly and replacement of the material bucket cover.

[0013] Furthermore, there are two lifting cylinders, which are arranged symmetrically.

[0014] The beneficial effects of adopting the above-mentioned further solution are that the two lifting cylinders are symmetrically arranged, which not only ensures the balance and levelness of the material bucket cover during the lifting process, but also allows the two cylinders to share the pressure when encountering a large load, avoiding damage caused by excessive force on a single cylinder, and further enhancing the stability and load-bearing capacity of the lifting mechanism.

[0015] Furthermore, the material bucket cover includes a top cover and a skirt portion surrounding the outer periphery of the top cover, the bottom of the skirt portion extending downwards, and a sealing gasket is also provided inside the material bucket cover.

[0016] The beneficial effect of adopting the above-mentioned further solution is that when the material bucket lid is placed on the opening of the turnover material bucket, the lid skirt can wrap around the outer edge of the opening, which can increase the sealing and stability of the material bucket lid and avoid the risk of the material bucket lid accidentally falling off. Moreover, in order to further increase the sealing effect between the material bucket lid and the turnover material bucket, a sealing gasket is added inside the material bucket lid. With the use of the sealing gasket, it is more effective to prevent powder leakage during the transfer of materials, ensuring the cleanliness and safety of the working environment, and improving the reliability and practicality of the entire material closed discharge device.

[0017] Furthermore, an upper clamp is provided at the connection between the connecting pipe and the mating flange.

[0018] The beneficial effects of adopting the above-mentioned further solution are that the upper clamp can ensure a more stable connection between the connecting pipe and the docking flange, prevent material leakage caused by loose connection during material transfer, improve the sealing performance of the device, ensure that the material in the airflow mixer can be smoothly transferred to the turnover hopper, and ensure the stability and safety of the entire discharge.

[0019] Furthermore, a lower clamp is provided at the connection between the connecting pipe and the material bucket cover.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the lower clamp strengthens the connection stability between the connecting pipe and the material bucket cover. Even if vibration occurs during the material transfer process, it can effectively prevent the connecting pipe and the material bucket cover from loosening, thereby avoiding the risk of material leakage caused by unstable connection, ensuring the continuity of material in the process of transferring and turning the material bucket, and providing a strong guarantee for efficient and safe material transfer.

[0021] This utility model also relates to a material transfer system, including an airflow mixer and a turnover hopper located below the airflow mixer for receiving and transferring the received material. It also includes a material sealing discharge device as described above. The docking flange of the material sealing discharge device is connected to the discharge pipe of the airflow mixer. Under the action of the lifting mechanism of the material sealing discharge device, the hopper cover of the material sealing discharge device can be lowered to seal and contact the hopper opening of the turnover hopper waiting to receive material.

[0022] The beneficial effects of this utility model are that, under the action of the lifting mechanism of the material closed discharge device, the hopper cover can accurately and quickly seal and contact the opening of the turnover hopper, which not only improves the efficiency of material discharge, but also ensures the sealing of the material discharge process, realizing the closed discharge and transfer of materials from the airflow mixer to the turnover hopper, effectively avoiding the problem of powder leakage during the transfer process, and ensuring the cleanliness of the production environment.

[0023] Furthermore, the airflow mixer is located in the upper region, the placement position of the turnover hopper is the hopper receiving position, the hopper receiving position is located in the lower region, and a partition is provided between the upper region and the lower region, as well as between the upper regions, and the partition is provided with a connecting hole.

[0024] The beneficial effects of adopting the above-mentioned further scheme are that the mixing capacity of the airflow mixer varies and its height is different. In terms of layout, the airflow mixer can be arranged on the upper floor of the building, and the material receiving position of the hopper can be arranged on the lower floor of the building. The material receiving position of the hopper is directly below the discharge pipe of the airflow mixer. The material mixed by the airflow mixer can be directly dropped into the turnover hopper.

[0031] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0032] like Figure 1 As shown, a closed material discharge device includes a connecting flange 1, a material bucket cover 2, a connecting pipe 3, and a lifting mechanism for driving the material bucket cover 2 to move up and down. The connecting flange 1 is used to connect to the discharge pipe of an airflow mixer. The material bucket cover 2 is adapted to the opening of a reusable material bucket 11. The material bucket cover 2 is equipped with a breather 9. The connecting pipe 3 is a flexible hose. The upper end of the connecting pipe 3 is connected to the connecting flange 1, and the lower end of the connecting pipe 3 is connected to the material bucket cover 2. Under the action of the lifting mechanism, the material bucket cover 2 moves downward to cover the reusable material bucket 11. The material from the airflow mixer can enter the reusable material bucket 11 through its discharge port and the connecting pipe 3 for closed discharge. Under the action of the lifting mechanism, the material bucket cover 2 can move upward to detach from the reusable material bucket 11, and the reusable material bucket 11 can transfer the received material.

[0033] The breather 9 has a filtration function and can replenish air, allowing external air to enter and maintain the pressure balance inside the turnover hopper 11, ensuring smooth material discharge.

[0034] The lifting mechanism includes at least one lifting cylinder 4, which is disposed between the docking flange 1 and the material bucket cover 2. The appropriate number of lifting cylinders 4 can be selected according to actual driving needs, ensuring smooth up-and-down movement of the material bucket cover 2. The lifting mechanism, using lifting cylinders 4, achieves smooth lifting of the material bucket cover 2. The lifting mechanism has a simple structure, automatic lifting, stable and reliable performance, ensuring the smooth operation of the sealed material discharge process. Furthermore, the lifting cylinders 4 are easy to maintain and replace, further improving the service life and operating efficiency of the entire device.

[0035] The docking flange 1 is equipped with a drive support plate 5, and the lifting cylinder 4 is connected to the docking flange 1 through the drive support plate 5. To accommodate the layout space of the lifting mechanism, the installation position of the lifting mechanism can be expanded by using the drive support plate 5, maintaining a distance between the lifting mechanism and the connecting pipe 3. This allows the lifting cylinder 4 to be more securely installed on the docking flange 1, while also ensuring smooth driving of the material bucket cover 2, thus improving the stability and reliability of the lifting mechanism. Furthermore, the drive support plate 5 facilitates the maintenance of the lifting cylinder 4.

[0036] The material bucket cover 2 is equipped with a connecting frame 6, and the lifting cylinder 4 is connected to the material bucket cover 2 through the connecting frame 6. The connecting frame 6 has a U-shaped structure. The open end of the U-shaped structure is connected to the top of the material bucket cover 2, and the closed end of the U-shaped structure is connected to the drive end of the lifting mechanism. This not only facilitates connection with the lifting mechanism, but also allows for the replacement of the material bucket cover 2 according to the size of the bucket opening when dealing with different sizes of turnover material buckets 11, making it convenient to disassemble and replace the material bucket cover 2. The cylinder body of the lifting cylinder 4 is connected to the drive support plate 5, and the piston rod of the lifting cylinder 4 is connected to the connecting frame 6.

[0037] Two lifting cylinders 4 are provided, and the two lifting cylinders 4 are symmetrically arranged. The symmetrical arrangement of the two lifting cylinders 4 not only ensures the balance and levelness of the material bucket cover 2 during the lifting process, but also allows the two cylinders to share the pressure when encountering a large load, avoiding damage caused by excessive force on a single cylinder. It can also further enhance the stability and load-bearing capacity of the lifting mechanism.

[0038] The material hopper cover 2 includes a top cover 21 and a skirt 22 surrounding the top cover 21. The bottom of the skirt 22 extends downwards, and a sealing gasket is also provided inside the material hopper cover 2. When the material hopper cover 2 is placed on the opening of the transfer hopper 11, the skirt 22 can wrap around the outer edge of the opening, which can increase the sealing and stability of the material hopper cover 2 and avoid the risk of the material hopper cover 2 accidentally falling off. Moreover, in order to further increase the sealing effect between the material hopper cover 2 and the transfer hopper 11 when it moves downwards, a sealing gasket is added inside the material hopper cover 2. With the use of the sealing gasket, powder leakage during material transfer is more effectively prevented, ensuring the cleanliness and safety of the working environment and improving the reliability and practicality of the entire closed material discharge device.

[0039] The upper clamp 7 is provided at the connection between the connecting pipe 3 and the docking flange 1. The upper clamp 7 can ensure a more stable connection between the connecting pipe 3 and the docking flange 1, prevent material leakage caused by loose connection during material transfer, improve the sealing performance of the device, ensure that the material in the airflow mixer 10 can be smoothly transferred to the transfer hopper 11, and ensure the stability and safety of the entire discharge.

[0040] A lower clamp 8 is provided at the connection between the connecting pipe 3 and the material bucket cover 2. The lower clamp 8 enhances the connection stability between the connecting pipe 3 and the material bucket cover 2. Even if vibration occurs during material transfer, it can effectively prevent the connecting pipe 3 and the material bucket cover 2 from loosening, thereby avoiding the risk of material leakage caused by unstable connection. This ensures the continuity of material in the transfer and turnover material bucket 11 process and provides a strong guarantee for efficient and safe material transfer.

[0041] like Figure 2 and Figure 3 As shown, this utility model also relates to a material transfer system, including an airflow mixer 10 and a turnover hopper 11 located below the airflow mixer 10 for receiving and transferring the received material. It also includes a material sealing discharge device as described above. The docking flange 1 of the material sealing discharge device is connected to the discharge pipe of the airflow mixer 10. Under the action of the lifting mechanism of the material sealing discharge device, the hopper cover 2 of the material sealing discharge device can be lowered to seal and contact the hopper opening of the turnover hopper 11 waiting to receive material.

[0042] The airflow mixer 10 is located in the upper area, and the placement position of the turnover hopper 11 is the hopper receiving position, which is located in the lower area. A partition 14 is provided between the upper and lower areas, and between the upper areas themselves. The partition 14 has a connecting hole 15. The airflow mixer 10 has varying mixing capacities and therefore different heights. In terms of layout, the airflow mixer 10 can be placed on the upper floor of the building, and the hopper receiving position can be placed on the lower floor. The hopper receiving position is directly below the discharge pipe of the airflow mixer 10. The mixed material from the airflow mixer 10 can directly fall into the turnover hopper 11. This material transfer system has a compact overall layout, makes reasonable use of workshop space, and is easy to operate, providing convenience for the material discharge and transfer of the airflow mixer 10.

[0043] Medium-sized airflow mixers 10 are typically around three meters high, with the material receiving area in the lower layer, such as the first floor. In this case, the airflow mixers 10 in the upper area can be placed on the second floor. Large airflow mixers 10 can reach a height of around nine meters, and can be placed on the second, third, or even fourth floor. There are staircases between adjacent floors.

[0044] The turnover hopper 11 is mounted on the turnover trolley frame 12, and a positioning baffle 13 is provided at the material receiving position of the hopper 11 for positioning the turnover hopper 11. Pushing the turnover trolley frame 12 to move the turnover hopper 11 allows operators to quickly and accurately place or remove the turnover hopper 11 at the material receiving position, making turnover convenient and fast. The positioning baffle 13 can limit the position of the turnover hopper 11 at the material receiving position, ensuring that the hopper lid 2 can move down to seal against the turnover hopper 11, ensuring that the material can be accurately and stably transferred into the turnover hopper 11.

[0045] The airflow mixer 10 of this utility model is arranged on the upper floor of the building, and a corresponding material receiving position is arranged on the lower floor. The turnover cart 12 can be manually pushed to move the turnover material hopper 11 to the material receiving position. Under the action of the lifting mechanism of the material sealing discharge device, the material hopper cover 2 can accurately and quickly seal and contact the opening of the turnover material hopper 11. When the material hopper cover 2 is in close contact with the opening of the turnover material hopper 11, the discharge valve of the airflow mixer 10 is opened, and the material is discharged. The material falls from the discharge pipe of the airflow mixer 10 to the connecting pipe 3, and then enters the turnover material hopper 11 through the opening, realizing the sealed discharge of material from the airflow mixer 10. This utility model ensures that the powder material smoothly enters the turnover material hopper 11 during the discharge process and eliminates the phenomenon of dust flying during the discharge process.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
