Description

Technical Field

[0001] The utility model relates to the technical field of ultrafine powder degassing, and specifically relates to ultrafine powder degassing equipment for packaging bags. Background Art

[0002] Ultrafine powders are often used in medicine or other special fields. In the packaging process of ultrafine powders, due to the fine particle size of the powder itself and the poor degassing effect of the packaging machine, there will be a large amount of material and air in the packaging bag, which will reduce the bulk density of the powder. When packaging, the net content of the material in the packaging bag will not meet the requirements.

[0003] When packaging ultrafine powders, a common solution is to let the powder stand for a period of time to allow the gas inside the powder to escape, thereby increasing the bulk density of the powder and ensuring that the net content of the powder in the packaging bag meets the requirements. However, this method takes a lot of time and cannot meet production needs when faced with large-scale and continuous operations.

[0004] Another way is to insert an air extraction pipe into the packaging bag to suck out the air inside the powder while preventing the material from being sucked out of the packaging bag, thereby increasing the bulk density of the powder. However, this method may cause blockage of the air extraction pipe when working for a long time. Utility Model Content

[0005] The utility model provides a degassing device for ultrafine powder in a packaging bag, which solves the problem in the related art that a filter rod may be blocked when working for a long time.

DETAILED DESCRIPTION

[0036] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, they can also be understood as further technical solutions without paying creative work. In some figures, components with the same structure or function are only schematically illustrated, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0037] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0038] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0039] Reference Figure 1~Figure 2 , which is the first embodiment of the utility model, proposes a degassing device for ultrafine powder in a packaging bag, comprising: a filter rod 2 is lifted and arranged on a support platform 1, and the filter rod 2 is a hollow structure; a fan 3 is connected to the filter rod 2 through an exhaust pipe 5, and the fan 3 is used to provide power for exhausting air. A back-blowing valve 4 is arranged on the exhaust pipe 5.

[0040] In this embodiment, the filter rod 2 has a plurality of air extraction holes. The diameter of the filter holes on the filter rod 2 is smaller than the minimum particle size of the powder, so the powder will be blocked outside the filter rod 2, and only the gas can pass through the filter holes. After the filter rod 2 is inserted into the material in the packaging bag, the fan 3 starts to work, and the fan 3 will continue to extract air to extract all the gas in the packaging bag. Due to the obstruction of the filter holes, the material will not be extracted by the fan 3. The filter rod 2 is used to extract the air in the material, which has a simple structure, low cost, and convenient production. Moreover, the requirements for the operator are low, and the operation is simple and easy to learn. The back-blowing valve 4 is set on the pipeline connecting the filter rod 2 and the fan 3. Even if the filter hole diameter of the filter rod 2 is small, there will still be smaller powder particles that cause the filter rod 2 to be blocked during continuous use. Therefore, it is necessary to set the back-blowing valve 4. The other end of the back-blowing valve 4 will be connected to the gas for back-blowing to blow through the blocked filter holes, thereby increasing the service life of the filter rod 2 and improving the working efficiency of the equipment.

[0041] As a further technical solution, it also includes: the telescopic member 6 is set on the support platform 1 for lifting, and the filter rod 2 is set at one end of the telescopic member 6 close to the material; there are two limit switches 7, both of which are set on the support platform 1, and the limit switches 7 are used to control the lifting range of the telescopic member 6.

[0042] In this embodiment, the telescopic part 6 is used to drive the filter rod 2 to rise and fall. When a vacuum operation is required, the telescopic part 6 needs to be moved up first so that the filter rod 2 can avoid the material conveying position. After rising to the specified position, the material will be conveyed to the bottom of the filter rod 2, and then the telescopic part 6 will continue to drive the filter rod 2 to descend, so that the filter rod 2 enters the packaging bag, and then a vacuum operation is performed to extract the gas in the packaging bag. After ensuring that there is no gas, the telescopic part 6 will rise to drive the filter rod 2 out of the packaging bag. By driving the telescopic member 6, the lifting and lowering of the filter rod 2 can be automatically realized, which ensures work efficiency, reduces labor intensity, and also improves work continuity. The limit switch 7 is installed on the base 1. After the telescopic member 6 rises to the specified position, it will touch the upper limit switch 7, thereby stopping the rising action of the telescopic member 6. When the telescopic member 6 descends, it will touch the lower limit switch 7, thereby stopping the descending action. Through the control of the two limit switches 7, the telescopic member 6 can automatically stop the action, further reducing the work intensity. At the same time, the lifting range can also be more accurately controlled, avoiding the damage of the packaging bag due to the failure of the telescopic member 6 to stop in time.

[0043] As a further technical solution, the present invention further includes: a tray 110 is lifted and lowered on the support platform 1 , and the tray 110 has a through hole 111 , and the filter rod 2 passes through the through hole 111 when being lifted and lowered.

[0044] In this embodiment, the tray 110 is penetrated by the filter rod 2, and the overall height can be adjusted, which ensures that the device can adapt to packaging bags of different sizes and improves the adaptability of the device.

[0045] As a further technical solution, it also includes: the two ends of the telescopic dust cover 8 are respectively arranged on the tray 110 and the filter rod 2.

[0046] In this embodiment, the telescopic dust cover 8 is arranged on the tray 110. Since the particle size of the material in the packaging bag is relatively fine, after the air is exhausted, when the filter rod 2 is pulled out of the packaging bag, some material will be taken out of the packaging bag and slowly fall from the top of the tray 110, causing the area around the equipment to be messy and taking more time to clean the equipment. The telescopic dust cover 8 is arranged on the top, which can effectively prevent dust from being scattered everywhere and ensure the cleanliness around the equipment. When the backflush valve 4 is backflushing, the telescopic dust cover 8 can also prevent dust from flying around, further ensuring the cleanliness of the equipment.

[0047] As a further technical solution, it also includes: a scraper 120 is arranged on the bottom surface of the tray 110, the scraper 120 is annular, and the inner wall of the scraper 120 abuts against the surface of the filter rod 2; and a vibrating member 130 is arranged at the end of the telescopic dust cover 8 away from the scraper 120.

[0048] In this embodiment, the scraper 120 is used to scrape the material adhering to the surface of the filter rod 2 off the surface of the filter rod 2, so that the material falls back into the packaging bag, thereby preventing waste of material and reducing the frequency of cleaning in the dust cover, thereby saving manual operation. The vibration member 130 is arranged in the telescopic dust cover 8. When the filter rod 2 rises, the vibration member 130 will vibrate, so that the material adhering to the filter rod 2 is shaken off the filter rod 2, thereby further reducing the amount of material adhering to the filter rod 2 and saving the amount of material loss.

[0049] As a further technical solution, it also includes: a guide member 140 is arranged on the side of the tray 110 away from the scraper 120, the guide member 140 is coaxial with the through hole 111, and the guide member 140 is used to guide the filter rod 2.

[0050] In this embodiment, the guide member 140 is tubular. When the filter rod 2 rises to the top, the filter rod 2 will be higher than the height at which the scraper 120 is separated from the tray 110. If the filter rod 2 is slightly deformed, the filter rod 2 may not be able to accurately enter the through hole 111 after it falls again, causing damage to the filter rod 2. The guide member 140 is set above the tray 110. Even if the filter rod 2 is lifted to the maximum height, it still cannot be separated from the guide member 140. Therefore, when the filter rod 2 descends, it will be guided by the guide member 140 and directly enter the through hole 111 without being damaged, thereby ensuring the integrity of the device.

[0051] As a further technical solution, the bottom of the filter rod is in an arc shape.

[0052] In this embodiment, the arc-shaped bottom of the filter rod 2 makes it easier for the filter rod 2 to enter the material inside the packaging bag, reduces the resistance received by the filter rod 2 during operation, and improves the efficiency of the equipment operation.

[0053] As a further technical solution, it also includes: a dust removal port 810 is arranged on the side of the telescopic dust cover 8 away from the tray 110.

[0054] In this embodiment, the dust removal port 810 is set at the top of the telescopic dust cover 8. When the back-blowing valve 4 is opened for back-blowing, the dust removal port 810 will block the flying dust from escaping from the inside of the dust cover. While ensuring that a large amount of back-blowing gas can leave the telescopic dust cover 8, it can also effectively prevent the material from flying away from the dust cover to ensure the cleanliness of the on-site environment.

[0055] As a further technical solution, the fan 3 is connected to the filter rod 2 via a steel wire hose.

[0056] In this embodiment, since the top of the telescopic dust cover 8 also needs to be adjusted to adapt to different materials, a steel wire hose is used for connection to ensure that the connection between the filter rod 2 and the fan 3 will not be restricted during adjustment, thereby improving the adaptability of the equipment.

[0057] As a further technical solution, it also includes: a three-way valve 510 is arranged on the steel wire hose, and the three-way valve 510 connects the two sides of the steel wire hose with the outside air respectively.

[0058] In this embodiment, the three-way valve 510 is used to communicate with the outside world. When vacuuming is required, the connection between the three-way valve 510 and the outside world is closed, and the fan 3 is turned on at the same time to ensure that the fan 3 can perform vacuuming and the gas in the packaging bag is extracted. After the extraction is completed, the three-way valve 510 is adjusted to allow the filter rod 2 to communicate with the outside world, so that gaps appear in the tightly combined materials, ensuring that the filter rod 2 can be separated from the packaging bag after the vacuuming is completed, thereby improving the continuous working ability of the equipment and improving the work efficiency.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
