Description

Technical Field

[0001] This utility model relates to the field of vacuum defoaming technology, and in particular to a vacuum pressure defoaming device. Background Technology

[0002] A vacuum pressure degassing device is an industrial equipment used to remove air bubbles from materials (such as liquids, colloids, pastes, etc.). It creates an environment of alternating vacuum and pressure, causing the air bubbles inside the material to rapidly expand, burst, and be expelled, thereby improving the density, uniformity, and reliability of the product. The core principle of a vacuum pressure degassing device is to eliminate air bubbles using changes in physical pressure. During operation, a vacuum pump reduces the air pressure inside the sealed cavity to create a vacuum environment. Under vacuum, the dissolved gases in the material precipitate out due to the decrease in solubility. At the same time, existing bubbles expand and rise to the surface and rupture due to the increased pressure difference between the inside and outside. A booster pump applies positive pressure, and the pressure difference further crushes and discharges the remaining or difficult-to-escape bubbles. By alternating between vacuum and pressure, bubbles can be removed more efficiently and thoroughly.

[0003] Existing vacuum pressure defoaming devices leave the working chamber at a high temperature after the defoaming process is completed. After processing, workers need to reach into the working chamber to retrieve materials. When reaching in to retrieve materials, the arm is very likely to accidentally touch the inside of the chamber, causing burns. To address this issue, the inventor has proposed a vacuum pressure defoaming device to solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this utility model is achieved through the following means: A vacuum pressure defoaming device includes a frame, a sealed tank, and a working component. The frame has an installation port in the middle that matches the sealed tank. One end of the sealed tank is fixedly connected to the installation port. One side of the sealed tank has an opening covered by a sealing cap. The inner side of the sealed tank has a working chamber that communicates with the opening. The upper and lower ends of the working chamber are horizontally arranged with a shelf. The working chamber has a retaining plate near both ends of the shelf, which is fixedly connected to the wall of the working chamber. The shelf is provided with a limiting protrusion matching the retaining plate near the retaining plate at the end away from the opening. The shelf is provided with guide protrusions near the retaining plate on both sides. The retaining plate is provided with a movable retaining block near the opening. A rectangular spring is connected between the movable retaining block and the limiting protrusion. The rectangular spring is fixedly connected to the movable retaining block and the limiting protrusion. The sealing cap is provided with a sealing surface near the opening. A circular top plate is provided on the sealing surface near the shelf, and the side wall of the circular top plate abuts against the side wall of the shelf.

[0005] In a further embodiment of the above description, a support platform for supporting the sealing tank is provided on the bottom inner side of the frame near the sealing tank. The top of the support platform adopts an arc-shaped structure that matches the sealing tank. The support platform cooperates with the sealing tube. A protective opening is provided on the outer side of the frame near the installation port. A protective door is covered on the protective opening. One end of the protective door is hinged to the outer side of the frame. The end of the sealing cover away from the sealing tank is connected to the protective opening through a hinged bracket. The protective door is used to cover the sealing cover to prevent workers from coming into contact with the sealing cover connected to the sealing tank during equipment processing and being burned by the sealing cover.

[0006] In a further embodiment of the above description, the outer circumference of the sealed container near the mounting port is provided with a connecting protrusion. An annular groove is formed on the side of the connecting protrusion near the sealing cover. Locking blocks are evenly distributed on the outer wall of the annular groove near the groove opening. The size and thickness of the sealing cover near the connecting protrusion are matched with the annular groove, and locking protrusions that are offset from the locking blocks are distributed in an annular shape along the edge of the sealing cover near the connecting protrusion. The annular groove and locking blocks on the connecting protrusion are used to cooperate with the locking protrusions, thereby achieving the sealing effect by rotating the sealing cover by rotating the handle, causing the locking protrusions to be offset from the locking blocks.

[0007] In a further embodiment of the above description, the sealing cover is rotatably connected to the hinge bracket. A rotating handle is located near the edge of the sealing cover on the hinge bracket. One end of the rotating handle extends through the hinge bracket toward the sealing cover, and a rotating gear is synchronously connected to the end of the rotating handle near the sealing cover. A drive rack that meshes with the rotating gear is located near the rotating gear on the sealing cover. During the sealing operation, the operator can insert the edge of the sealing cover into the annular groove and then twist the rotating handle. The rotating handle drives the rotating gear to control the rotation of the sealing cover via the drive rack, thereby misaligning the locking protrusion with the locking block to achieve a locking effect.

[0008] In a further embodiment of the above description, the working components include a heating wire, a circulating fan, a vacuum pump, and a booster pump. The heating wire is fixedly installed inside the sealed container at the end away from the sealing cover, and the connecting end of the heating wire extends through the sealed container toward the outer side of the sealed container. A partition cover is fixedly installed inside the sealed container near the heating wire. Flow ports are provided at the upper and lower ends of the partition cover near the shelf. The circulating fan is fixedly installed on the flow ports. A protective net is provided inside the partition cover near the heating wire. The partition cover is used to provide protection for the circulating fan, while the protective net is used to provide protection for the heating wire.

[0009] In a further embodiment of the above description, the top surface of the sealed container has connection ports at both ends. Both the vacuum pump and the booster pump are installed on the top of the inner side of the frame near the connection ports. A partition plate is also present on the top of the frame near the connection ports. The air inlet of the vacuum pump is connected to the connection port at one end of the top surface of the sealed container, and the air outlet of the vacuum pump extends outwards towards the frame. The air outlet of the booster pump is connected to the connection port at the other end of the top surface of the sealed container. A gas storage tank is located on one side of the booster pump, and the air inlet of the booster pump is connected to the gas storage tank. The booster pump provides positive pressure, while the vacuum pump creates a vacuum inside the sealed container.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: A limiting protrusion matching the card plate is provided at the end of the shelf away from the opening, near the card plate. Guide protrusions are provided on both sides of the shelf near the card plate. A movable card block is detachably provided at the end of the card plate near the opening. A rectangular spring connects the movable card block and the limiting protrusion, and the rectangular spring is fixedly connected to the movable card block and the limiting protrusion. Simultaneously, a circular top plate is provided on the sealing surface near the shelf. The circular top plate is fitted against the shelf. When the sealing cover is not opened, the circular top plate abuts against the side wall of the shelf, thus limiting the shelf. At this time, the rectangular spring is in a stretched state. When the sealed container is opened, the circular top plate flips with the sealing cover. After the shelf loses its limiting effect, the stretched rectangular spring begins to rebound. Simultaneously, it moves towards the opening of the sealed container through the limiting protrusion, thus popping the shelf towards the opening of the sealed container. This allows workers to directly remove materials without having to put their hands into the container, thus avoiding burns to their arms. Attached Figure Description

Detailed Implementation

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] For this embodiment, please refer to Figures 1-7 The vacuum pressure defoaming device specifically implemented includes a frame 1, a sealed tank 2, and working components. The frame 1 has a mounting port 3 in the middle that matches the sealed tank 2. One end of the sealed tank 2 is fixedly connected to the mounting port 3. An opening 4 is provided on one side of the sealed tank 2, and a sealing cap 5 is placed over the opening 4. A working chamber 6 is provided inside the sealed tank 2, communicating with the opening 4. A placement plate 7 is horizontally arranged at both the upper and lower ends of the working chamber 6. A retaining plate 8 is provided near both ends of the placement plate 7 within the working chamber 6, and the retaining plates 8 are fixedly connected to the wall of the working chamber 6. The placement plates 7 are located away from... One end of the opening 4 is provided with a limiting protrusion 9 that matches the card plate 8. Both sides of the shelf 7 are provided with guide protrusions 10 near the card plate 8. The card plate 8 is provided with a movable card block 11 that is detachable at one end near the opening 4. A rectangular spring 12 is connected between the movable card block 11 and the limiting protrusion 9. The rectangular spring 12 is fixedly connected to the movable block and the limiting protrusion 9. The sealing cover 5 is provided with a sealing surface 13 on the side near the opening 4. A circular top plate 14 is provided on the sealing surface 13 near the shelf 7. The side wall of the circular top plate 14 abuts against the side wall of the shelf 7. Specifically, when the sealed container 2 is opened, the circular top plate 14 flips up along with the sealing cover 5. At this time, the shelf 7 loses its limiting effect, and the stretched rectangular spring 12 begins to rebound. While rebounding, it moves towards the opening 4 of the sealed container 2 through the limiting protrusion 9, thereby popping the shelf 7 towards the opening 4 of the sealed container 2, making it easier for staff to directly take out the materials.

[0014] The bottom inner side of the frame 1 is provided with a support platform 15 for supporting the sealing tank 2 near the sealing tank 2. The top of the support platform 15 adopts an arc-shaped structure that matches the sealing tank 2. The support platform 15 cooperates with the sealing tube. The outer side of the frame 1 is provided with a protective opening 16 near the installation port 3. A protective door 17 is covered on the protective opening 16. One end of the protective door 17 is hinged to the outer side of the frame 1. The end of the sealing cover 5 away from the sealing tank 2 is connected to the protective opening 16 through a hinge bracket 18. Specifically, the protective door 17 is placed on the side of the sealing cover 5 away from the sealing tank 2. During the defoaming process, since the sealing cover 5 is connected to the sealing tank 2, the heating temperature of the heating wire 26 will still be conducted to the sealing cover 5 when the defoaming temperature is reached. Therefore, in order to prevent workers from being burned by directly contacting the sealing cover 5 during processing, the sealing cover 5 is covered by the protective door 17.

[0015] The outer circular surface of the sealed container 2 is provided with a connecting protrusion 19 near the installation port 3. An annular groove 20 is provided on the side of the connecting protrusion 19 near the sealing cover 5. Locking blocks 21 are evenly distributed on the outer wall of the annular groove 20 near the groove opening. The size and thickness of the sealing cover 5 near the connecting protrusion 19 are matched with the annular groove 20. Locking protrusions 22 that are offset from the locking blocks 21 are distributed in annularly along the edge of the sealing cover 5 near the connecting protrusion 19. Specifically, when the sealing cap 5 needs to be fastened onto the sealing container 2, the locking protrusion 22 on the sealing cap 5 is rotated by turning the handle 23 to the position between the locking blocks 21 and the locking blocks 21. Then, the sealing cap 5 and the locking protrusion 22 are inserted into the annular groove 20. Then, the handle 23 is turned to make the locking protrusion 22 coincide with the locking block 21, thus realizing the connection between the sealing cap 5 and the sealing tube.

[0016] The sealing cover 5 is rotatably connected to the hinge bracket 18. A rotating handle 23 is provided on the hinge bracket 18 near the edge of the sealing cover 5. One end of the rotating handle 23 extends through the hinge bracket 18 toward the sealing cover 5, and a rotating gear 24 is synchronously connected to the end of the rotating handle 23 near the sealing cover 5. A drive rack 25 that meshes with the rotating gear 24 is provided on the sealing cover 5 near the rotating gear 24. Specifically, through the design of the drive rack 25 and the rotating gear 24, and by using the blank areas provided at both ends of the drive rack 25, when the sealing cover 5 rotates, causing the drive rack 25 to rotate into the blank area, the rotation angle of the sealing cover 5 can be limited, making it convenient for operators to control.

[0017] The working components include a heating wire 26, a circulating fan 27, a vacuum pump 28, and a booster pump 29. The heating wire 26 is fixedly installed inside the sealed tank 2 at the end away from the sealing cover 5, and the connecting end of the heating wire 26 extends through the sealed tank 2 toward the outer side of the sealed tank 2. A partition cover 30 is fixedly installed inside the sealed tank 2 near the heating wire 26. The upper and lower ends of the partition cover 30 are provided with flow ports 31 near the shelf 7. The circulating fan 27 is fixedly installed on the flow ports 31. A protective net 32 ​​is provided inside the partition cover 30 near the heating wire 26.

[0018] Both ends of the top surface of the sealed tank 2 are provided with connection ports 33. The vacuum pump 28 and the booster pump 29 are both installed on the top of the inner side of the frame 1 near the connection ports 33. There is also a partition plate 34 on the top of the frame 1 near the connection ports 33. The air inlet of the vacuum pump 28 is connected to the connection port 33 at one end of the top surface of the sealed tank 2. The air outlet of the vacuum pump 28 extends outward toward the frame 1. The air outlet of the booster pump 29 is connected to the connection port 33 at the other end of the top surface of the sealed tank 2. A gas storage tank 35 is provided on one side of the booster pump 29. The air inlet of the booster pump 29 is connected to the gas storage tank 35. It should be noted that the connection effect, connection method and movement of the circulating fan 27, heating wire 26, booster pump 29, vacuum pump 28 and sealing tank 2 in the working components are all existing technologies of vacuum pressure defoaming machines on the market. The circuit program involved can also be applied in this application. It will not be described in detail here. The attached drawings are only for illustration and do not have a limiting effect. Those skilled in the art should be able to make reasonable selections and designs according to the actual situation.

[0019] The workflow of this application: 1) Placing the product: Place the product to be processed on the shelf 7, push the shelf 7 into the sealed container 2, and then flip the sealing cover 5 towards the sealed container 2. At the same time, the circular top plate 14 will abut against the side wall of the shelf 7 until the shelf 7 is completely inside the sealed container 2 and until the sealing cover 5 is completely attached to the sealing cover 2. At the same time, the sealing cover 5 and the locking protrusion 22 are engaged in the annular groove 20. Then, control the rotating handle 23 to drive the rotating gear 24 to rotate. The rotating gear 24 drives the sealing cover 5 to rotate through the drive rack 25 until the locking protrusion 22 coincides with the locking block 21, thus realizing the connection between the sealing cover 5 and the sealing tube. Finally, close the protective door 17. 2) Processing the product: The vacuum pump 28 is turned on to reduce the gas pressure in the sealed container 2, forming a vacuum environment. Then, under vacuum, the gas dissolved in the material will precipitate due to the decrease in solubility. At the same time, the existing bubbles will expand due to the increase in internal and external pressure difference, accelerate to rise to the surface and rupture. Then, the pressurized gas in the gas storage tank 35 is drawn by the booster pump 29 and injected into the sealed container 2 to apply positive pressure. The pressure difference is used to further crush and discharge the residual or difficult-to-escape bubbles, thus removing the bubbles. During the above steps, the heating wire 26 is used to heat the sealed container 2 to provide the temperature required for the process. 3) Removing the product: After the process is completed, open the protective door 17 and the sealing cover 5. At the same time, the circular top plate 14 flips along with the sealing cover 5. At this time, the shelf 7 loses its limiting effect, and the stretched rectangular spring 12 begins to rebound. While rebounding, it moves towards the opening 4 of the sealing tank 2 through the limiting protrusion 9, thereby popping the shelf 7 towards the opening 4 of the sealing tank 2, making it easier for the staff to remove the product.
