Description

Technical Field

[0001] This invention belongs to the field of coating machine technology, and in particular relates to a desktop fluidized bed and coating machine integrated equipment. Background Technology

[0002] A fluidized bed, or simply fluidized bed, is a reactor that uses gas or liquid to pass through a layer of particulate solids, causing the solid particles to be in a suspended state and carrying out gas-solid or liquid-solid phase reaction processes. A high-efficiency coating machine is a highly efficient, energy-saving, safe, and clean mechatronic device that can perform organic film coating, water-soluble film coating, and sustained-release or controlled-release coating on tablets, pills, candies, etc. It is suitable for the pharmaceutical, chemical, and food industries.

[0003] In existing systems where coating machines and fluidized beds share a common cabinet, fine impurities from the coating machine and fluidized bed tend to fall onto the joints on the common cabinet when they separate from it. This can affect the sealing of the joints when they are reconnected to the coating machine and fluidized bed. Therefore, a desktop integrated device for fluidized bed and coating machine is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a desktop fluidized bed and coating machine integrated device that can prevent material accumulation on the joints, avoid affecting the sealing performance of the joints and connecting pipes, improve the sealing effect over long-term use, and filter the gas entering the common cabinet through the filter screen to prevent impurities in the air from entering the fluidized bed body or the coating machine main unit. It can also automatically clean the filter screen, improve the automation level of the equipment, and solve the existing technical problems.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] A desktop fluidized bed and coating machine integrated device includes: a fluidized bed body, a coating machine main unit and a common cabinet. The bottom of the fluidized bed body and the coating machine main unit are both equipped with connecting pipes. A fan is fixedly connected to the bottom inner wall of the common cabinet. An air inlet pipe and an air outlet pipe are fixedly connected to one side of the common cabinet. The air outlet pipe is connected to the air outlet end of the fan.

[0007] An extension plate is provided, on the surface of which a set of cylinders are fixedly connected. A lifting plate is fixedly connected between one end of the piston rod of the cylinders. A connector for docking with the connecting pipe is rotatably connected to the top of the lifting plate. A telescopic pipe is fixedly connected between the connector and the air outlet pipe.

[0008] A cleaning mechanism is provided on one side of the connector to clean impurities from the connector head.

[0009] Furthermore, an air inlet box is fixedly connected to the top inner wall of the shared cabinet. The air inlet box is located on one side of the air inlet pipe. A filter screen for gas filtration is inserted between the two inner walls of the air inlet box. The top of the filter screen passes through the top of the shared cabinet. The filter screen can filter the gas entering the shared cabinet and prevent impurities in the air from entering the fluidized bed body or the coating machine main unit.

[0010] Furthermore, two connecting frames are fixedly connected to one side of the lifting plate. L-shaped sliding rods are fixedly connected to the top inner walls of the two connecting frames. The sliding rods slide through the top of the air intake box and the common cabinet. A scraper for cleaning the filter screen is slidably sleeved between the two sliding rods. Springs are fixed between the scraper and the sliding rod. During the movement of the lifting plate, the scraper can drive the scraper to clean the filter screen, improve the filtration effect of the filter screen, and prevent it from clogging.

[0011] Furthermore, both inner walls of the air intake box are provided with guide components for guiding the scraper. The guide components include a positioning plate, which is fixed to one inner wall of the air intake box. The scraper is located between the positioning plate and the filter screen. The top of the positioning plate is fixedly connected to an installation shaft, and the circumferential rotation of the installation shaft is connected to a guide plate for guiding the scraper. A second torsion spring is fixedly connected between the guide plate and the installation shaft. During the cleaning process of the filter screen, the spring can also be used to push the scraper to reset, thereby impacting the filter screen and further cleaning it.

[0012] Furthermore, the cleaning mechanism includes a flexible connecting pipe, which is fixed to the surface of the lifting plate and penetrates the lifting plate. One end of the connecting pipe is located on one side of the connector, and the other end of the connecting pipe is located inside the air inlet pipe. After the connector is used, the debris or other impurities on the side can be extracted by the connecting pipe, thereby preventing material accumulation on the connector, avoiding affecting the sealing performance of the connector and the connecting pipe, and improving the sealing effect for long-term use.

[0013] Furthermore, a pull rope is wound around the circumference of the joint, and the other end of the pull rope passes through the lifting plate and is fixed to the extension plate. A first torsion spring is fixedly connected between the bottom of the joint and the lifting plate.

[0014] Furthermore, a guide roller is fixedly connected to the surface of the lifting plate, and the pull rope passes around the guide roller.

[0015] Furthermore, a heating box is fixedly connected to the bottom inner wall of the shared cabinet, and multiple heating wires are fixedly connected between the two inner walls of the heating box. A partition is fixedly connected to the bottom inner wall of the heating box, and the top of the partition does not contact the heating box. The heating box is located between the air outlet pipe and the air outlet end of the fan, connecting them.

[0016] Furthermore, a protective cover is fixedly connected to one side of the outer wall of the shared cabinet, and the protective cover is located on one side of the air inlet pipe.

[0017] Furthermore, the bottom of the air intake box is provided with a collection box for collecting impurities.

[0018] The embodiments of the present invention have the following beneficial effects:

[0019] In this invention, by installing a cleaning mechanism on one side of the connector, debris or other impurities on the side of the connector can be extracted by the connecting pipe after use, thereby preventing material accumulation on the connector, avoiding affecting the sealing performance of the connector and the connecting pipe, and improving the sealing effect for long-term use.

[0020] In this invention, by installing a filter screen in the air inlet box, the gas entering the common cabinet can be filtered through the filter screen, preventing impurities in the air from entering the fluidized bed body or the coating machine main unit.

[0021] In this invention, by installing a scraper on one side of the filter screen, the scraper can be driven to clean the filter screen during the movement of the lifting plate, thereby improving the filtration effect of the filter screen and preventing it from clogging.

[0022] In this invention, the scraper is designed to be movable, so that during the cleaning process of the filter screen, the scraper can be pushed back by a spring to impact the filter screen and further clean it.

[0023] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0036] Example 1

[0037] Please see Figures 1-7 As shown, this embodiment provides a desktop fluidized bed and coating machine integrated device, including: a fluidized bed body 1, a coating machine main unit 2, and a common cabinet 4. The bottom of both the fluidized bed body 1 and the coating machine main unit 2 are equipped with connecting pipes 3. A fan 23 is fixedly connected to the bottom inner wall of the common cabinet 4. A connecting air inlet pipe 10 and an air outlet pipe 22 are fixedly connected to one side of the common cabinet 4. The air outlet pipe 22 is connected to the air outlet end of the fan 23.

[0038] An extension plate 5 is fixedly connected to a set of cylinders 6. A lifting plate 7 is fixedly connected to one end of the piston rod of the cylinder 6. A connector 9 for docking with the connecting pipe 3 is rotatably connected to the top of the lifting plate 7. A telescopic pipe 8 is fixedly connected between the connector 9 and the air outlet pipe 22. When the cylinder 6 is activated, the cylinder 6 can drive the lifting plate 7 to move upward, and then drive the connector 9 to rise through the lifting plate 7, thereby completing the docking with the connecting pipe 3 on the fluidized bed body 1 or the coating machine main unit 2.

[0039] The cleaning mechanism is located on one side of the connector 9 to clean impurities on the connector 9.

[0040] Example 2

[0041] Improvements based on Example 1: See Appendix Figures 1-7 ,

[0042] Reference Figure 4 An air inlet box 12 is fixedly connected to the top inner wall of the shared cabinet 4. The air inlet box 12 is located on one side of the air inlet pipe 10. A filter screen 13 for filtering gas is inserted between the two inner walls of the air inlet box 12. The top of the filter screen 13 passes through the top of the shared cabinet 4. At the same time, the gas first enters the air inlet box 12 through the air inlet pipe 10, and then enters the shared cabinet 4 after being filtered by the filter screen 13, thereby improving the cleanliness of the air.

[0043] Reference Figure 5 Two connecting frames 15 are fixedly connected to one side of the lifting plate 7. L-shaped sliding rods 16 are fixedly connected to the top inner walls of the two connecting frames 15. The sliding rods 16 slide through the top of the air intake box 12 and the common cabinet 4. A scraper 18 for cleaning the filter screen 13 is slidably sleeved between the two sliding rods 16. A spring 17 is fixed between the scraper 18 and the sliding rod 16. When the lifting plate 7 rises, it drives the connecting frame 15 to move upward. The connecting frame 15 drives the scraper 18 to rise through the sliding rod 16, thereby cleaning the impurities and dust on the surface of the filter screen 13 and reducing the number of manual cleaning times.

[0044] Reference Figure 5 and Figure 7The inner walls of both sides of the air intake box 12 are provided with guide components for guiding the scraper 18. The guide components include a positioning plate 28, which is fixed to one inner wall of the air intake box 12. The scraper 18 is located between the positioning plate 28 and the filter screen 13. The top of the positioning plate 28 is fixedly connected to the mounting shaft 29. The mounting shaft 29 is rotatably connected to the guide plate 30 for guiding the scraper 18. A second torsion spring 31 is fixedly connected between the guide plate 30 and the mounting shaft 29. During the upward movement, the scraper 18 pushes the guide plate 30 open and then moves above the guide plate 30. When the scraper 18 returns to its original position with the slide rod 16, the scraper 18 moves backward along the guide plate 30 and then slides downward along the positioning plate 28. After the slide is in place, it is pushed by the spring 17 to approach the filter screen 13 and then impact the filter screen 13, thereby shaking off the dust on the filter screen 13 and improving the cleaning effect.

[0045] Reference Figure 6 The cleaning mechanism includes a flexible connecting pipe 27, which is fixed to the surface of the lifting plate 7 and passes through the lifting plate 7. One end of the connecting pipe 27 is located on one side of the connector 9, and the other end of the connecting pipe 27 is located inside the air inlet pipe 10. The connecting pipe 27 is connected to the air inlet pipe 10, so that the connecting pipe 27 has suction force, thereby extracting foreign objects on the connector 9.

[0046] A pull rope 25 is wrapped around the circumference of the connector 9. The other end of the pull rope 25 passes through the lifting plate 7 and is fixed to the extension plate 5. A first torsion spring 26 is fixedly connected between the bottom of the connector 9 and the lifting plate 7. When the lifting plate 7 rises, the connector 9 rotates under the pull of the pull rope 25, which in turn causes the second torsion spring 31 to be stressed. Then, when the lifting plate 7 returns to its original position, the connector 9 rotates, which improves the cleaning effect on the connector 9. A guide roller 24 is fixedly connected to the surface of the lifting plate 7, and the pull rope 25 passes around the guide roller 24.

[0047] Reference Figure 4 A heating box 19 is fixedly connected to the bottom inner wall of the common cabinet 4. Multiple heating wires 21 are fixedly connected between the two inner walls of the heating box 19. A partition 20 is fixedly connected to the bottom inner wall of the heating box 19. The top of the partition 20 does not contact the heating box 19. The heating box 19 is located between the air outlet pipe 22 and the air outlet end of the fan 23, connecting them. The heating wires 21 can heat the air, which is convenient for drying the raw materials.

[0048] Reference Figure 4 A protective cover 11 is fixedly connected to one side of the outer wall of the shared cabinet 4. The protective cover 11 is located on one side of the air inlet pipe 10. The protective cover 11 is in a breathable state and can block large foreign objects.

[0049] Reference Figure 4The bottom of the air intake box 12 is provided with a collection box 14 for collecting impurities. The collection box 14 runs through the side of the air intake box 12 and the common cabinet 4, making it easy to remove and clean. The collection box 14 is used to collect the impurities that have been cleaned.

[0050] The usage process and working principle of the technical solution of this invention are as follows:

[0051] In use, the fluidized bed body 1 or the coating machine main unit 2 is connected to the connector 9 through the bottom connecting pipe 3. When connecting, the cylinder 6 is started, and the cylinder 6 drives the lifting plate 7 to move upward, which in turn drives the connector 9 to rise, thereby completing the docking with the connecting pipe 3.

[0052] Start the fan 23 and heating wire 21. The fan 23 will charge the heated air into the fluidized bed body 1 or the coating machine main unit 2 through the air outlet pipe 22, the telescopic pipe 8 and the connector 9, thereby drying the raw materials inside. At the same time, the gas first enters the air inlet box 12 through the air inlet pipe 10, and then enters the common cabinet 4 after being filtered by the filter screen 13. Then the fan 23 blows it into the heating box 19.

[0053] When the lifting plate 7 rises, it drives the connecting frame 15 to move upward. The connecting frame 15 drives the scraper 18 to rise through the slide rod 16, thereby cleaning the impurities and dust on the surface of the filter screen 13. During the rising process, the scraper 18 pushes open the guide plate 30 and then moves above the guide plate 30. When the scraper 18 returns to its original position with the slide rod 16, the scraper 18 moves backward along the guide plate 30 and then slides downward along the positioning plate 28. After the slide is in place, it is pushed by the spring 17 to approach the filter screen 13 and then impact the filter screen 13, thereby shaking off the dust on the filter screen 13 and improving the cleaning effect.

[0054] When the lifting plate 7 rises, the connector 9 rotates under the pull of the pull rope 25, which in turn causes the second torsion spring 31 to be stressed. Then, when the lifting plate 7 returns to its original position, the connector 9 rotates, and the connecting pipe 27 is connected to the air inlet pipe 10, so that the connecting pipe 27 has suction force, thereby extracting foreign objects from the connector 9.
