Description

Technical Field

[0001] This utility model relates to the field of powder processing technology, specifically to a powder material lifting device. Background Technology

[0002] In modern industrial production, the processing of powder materials is widely used in many fields such as chemical, food, and pharmaceutical industries, especially in biopharmaceuticals, where its application is even more critical. To facilitate material handling by operators, powder material processing equipment is usually installed on a frame at a certain height. The frame elevates the equipment, allowing operators to easily access the discharge port at the bottom of the equipment for material handling.

[0003] However, this method of mounting powder material processing equipment on a frame at a certain height has revealed significant drawbacks in practical use. In the biopharmaceutical field, because the equipment is elevated, it is difficult for workers to easily pour powder materials into the equipment. This not only increases physical exertion and significantly raises the workload, but also may lead to material contamination due to improper operation, affecting drug quality and safety. At the same time, the extended operation time caused by inconvenient material transportation also reduces the overall efficiency of powder material processing to some extent, limiting production progress and hindering companies from improving production efficiency and market competitiveness. Utility Model Content

[0004] The purpose of this invention is to solve the problem that powder materials are difficult to lift and transport conveniently from a low position in the prior art, and to provide a powder material lifting device.

[0005] To address the shortcomings of the aforementioned technical problems, the present invention adopts the following technical solution: a powder material lifting device, which has a lifting component that can be elastically connected to the processing equipment and a lifting pipe that can be connected to the storage cylinder for storing powder materials. The lifting pipe is connected to the lifting component through an elastic part, and the lifting component is provided with a counterweight that can cooperate with the elastic part to vibrate the lifting pipe under the drive of the lifting component. The lifting component includes a temporary storage cylinder supported by a load component. The temporary storage cylinder is connected to a vacuum pump, and the temporary storage cylinder is provided with an opening and closing plate facing the processing equipment. The opening and closing plate is driven by an opening and closing component to cooperate with the vacuum pump to evacuate the inside of the temporary storage cylinder, or to cooperate to discharge the material inside the temporary storage cylinder. The counterweight includes a counterweight block that engages with the elastic part to increase the amplitude of the lifting tube.

[0006] As a further optimization of the powder material lifting device of this utility model: the temporary storage cylinder is fixedly connected to a connecting plate, the connecting plate is connected to a vacuum pump, the connecting plate is connected to two horizontal shafts of the load, and the two horizontal shafts are connected to a load frame for support.

[0007] As a further optimization of the powder material lifting device of this utility model: the connecting plate is provided with a connecting hole that mates with the horizontal shaft, and the bottom of the connecting plate is provided with multiple plug sleeves, which are fitted with plug rods to limit the horizontal shaft into the connecting hole.

[0008] As a further optimization of the powder material lifting device of this utility model: a pull plate is fixedly provided at the end of the multiple plug rods that protrude from the connecting plate.

[0009] As a further optimization of the powder material lifting device of this utility model: the counterweight block is slidably fitted with a guide rail provided on the temporary storage cylinder.

[0010] As a further optimization of the powder material lifting device of this utility model: the connection between the counterweight and the elastic part is C-shaped.

[0011] As a further optimization of the powder material lifting device of this utility model: the temporary storage cylinder is provided with a vertically arranged observation window on its outer periphery.

[0012] As a further optimization of the powder material lifting device of this utility model: an elastic sealing ring is provided on the outer periphery of the opening and closing plate.

[0013] As a further optimization of the powder material lifting device of this utility model: the opening and closing component includes a rotating shaft rotatably mounted on a temporary storage cylinder, a sealed bearing is provided at the connection between the rotating shaft and the temporary storage cylinder, the rotating shaft is fixedly connected to the center of the opening and closing plate, and the rotating shaft is driven by a stepper motor mounted on the temporary storage cylinder.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention effectively reduces the pressure inside the temporary storage cylinder by incorporating a vacuum pump connected to it. Subsequently, using a lift pipe connected to the storage cylinder, the powder material in the lower storage cylinder is lifted and pumped into the temporary storage cylinder for storage, thus avoiding the tedious process of manually lifting materials to a higher position.

[0015] This invention, by setting a counterweight on the temporary storage cylinder, can support and cooperate with the vibration generated by the temporary storage cylinder during the vacuuming process, so as to resonate the powder material in the lifting tube, which significantly reduces the risk of blockage or excessive friction at a single position during the lifting process.

[0016] This invention, by incorporating opening and closing components and plates, enables communication between the temporary storage cylinder and the processing equipment after the powder material in the cylinder is full and the vacuum pump operation is stopped. This ensures that the powder material can be quickly and efficiently transported to the processing equipment for processing. Furthermore, the temporary storage cylinder can be subsequently closed and resealed to achieve a process of re-suction and lifting of the powder material from a lower position.

[0018] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0019] like Figure 1 and Figure 2 As shown, it has a lift pipe 2 for sucking powder material from the storage cylinder 1, and a lifting member 5 that is elastically connected to the feed inlet of the processing equipment 7. The lift pipe 2 is connected to the temporary storage cylinder 509 included in the lifting member 5 via an elastic part 3, specifically, the elastic part 3 is a vertically extendable elastic tube. This design ensures that when the inside of the lifting member 5 is empty, the operator can control the vacuuming operation, thereby creating a negative pressure between the storage cylinder 1 and the temporary storage cylinder 509 inside the lifting member 5. The generation of negative pressure is based on Bernoulli's principle, that is, the pressure is low where the flow velocity is high. By reducing the air pressure inside the temporary storage cylinder 509 through vacuuming, the powder material in the storage cylinder 1 is sucked into the temporary storage cylinder 509 under the action of the air pressure difference. Subsequently, the powder material in the storage cylinder 1 can be easily extracted into the temporary storage cylinder 509 using the lift pipe 2. During the extraction process, the vibration of the temporary storage cylinder 509 plays a key role. This vibration not only helps the powder material fall evenly into the temporary storage cylinder 509, preventing material accumulation, but also causes the riser pipe 2 to vibrate accordingly. This vibration effect helps reduce the probability of powder material clogging in the riser pipe 2, ensuring smooth material flow. Specifically, the connection between the temporary storage cylinder 509 and the processing equipment 7 of the lifting component 5 is provided with an elastic rubber cylinder, and other elastic connecting cylinders are also acceptable, as long as it can ensure that the temporary storage cylinder 509 can vibrate.

[0020] A counterweight 4 is provided on the temporary storage cylinder 509, which further enhances the vibration effect of the riser tube 2. The working principle of the counterweight 4 is based on the principle of resonance. When the temporary storage cylinder 509 vibrates during the vacuuming process, the counterweight block 401 inside the counterweight 4 is stably vertically displaced under the support of the elastic part 3, thereby amplifying the vibration amplitude of the elastic part 3. This amplified vibration can drive the riser tube 2 to produce relatively stable irregular vibration, further reducing the risk of powder material blockage.

[0021] The counterweight 401 has a certain weight, which allows it to resonate synchronously under the vibration drive of the temporary storage cylinder 509. The cooperation between the counterweight 401 and the elastic part 3 provides auxiliary vibration for the lifting tube 2, thereby ensuring that the powder material can be stably and smoothly lifted into the temporary storage cylinder 509. A vertically arranged limiting post 403 is fixedly installed inside the guide rail 402, which is slidably connected to the counterweight 401, increasing the stability of the vertical displacement of the counterweight 401. The C-shaped design at the connection between the counterweight 401 and the elastic part 3 allows the operator to connect or separate the two for use as needed.

[0022] like Figure 1 As shown, the temporary storage cylinder 509 is connected to a vacuum pump 501 capable of extracting air from its interior. The vacuum pump 501 is mounted on the connecting plate 502, facilitating operator control of the vacuuming process inside the temporary storage cylinder 509. Simultaneously, the vibration of the vacuum pump 501 during operation, in conjunction with the vibration of the temporary storage cylinder 509 and the counterweight 401, further enhances the resonance effect on the riser pipe 2. This resonance causes the riser pipe 2 to undergo relatively stable irregular vibrations to a certain extent, contributing to the smooth flow of materials.

[0023] A viewing window 506 is provided on the temporary storage cylinder 509 for operators to observe the material storage level. This helps operators to promptly understand the amount of powder material inside the temporary storage cylinder 509 for subsequent operations. An opening / closing plate 508 is sealed inside the temporary storage cylinder 509 near the processing equipment 7, driven by an opening / closing component 507 located on the temporary storage cylinder 509. When the powder material inside the temporary storage cylinder 509 is sufficient, the operator can control the vacuuming operation to end and use the opening / closing component 507 to open the opening / closing plate 508, smoothly conveying the material in the temporary storage cylinder 509 to the processing equipment 7 for processing.

[0024] When it is necessary to lift powdered material, the operator can control the opening and closing plate 508 to rotate via the opening and closing component 507 to seal the bottom of the temporary storage cylinder 509. Then, the vacuum pump 501 is used to evacuate the air inside the temporary storage cylinder 509, creating a pressure difference between the temporary storage cylinder 509 and the storage cylinder 1, thereby drawing in the powdered material. This process greatly simplifies the tedious steps of moving materials to a higher position and then pouring them in, effectively reducing workload and improving the efficiency of powdered material processing to a certain extent. The processing equipment 7 is mounted on the support frame 8, with its discharge port exposed at a certain height, facilitating the collection of processed powdered particles at the discharge port by the operator. This not only improves work efficiency but also ensures the safety of the operator.

[0025] like Figure 2 As shown, the opening / closing component 507 includes a stepper motor 5071 located outside the temporary storage cylinder 509 and a rotating shaft 5072 rotatably mounted on the temporary storage cylinder 509. Specifically, the rotating shaft 5072 is rotatably connected to the temporary storage cylinder 509 via a sealed bearing. The rotating shaft 5072 is centrally fixedly connected to the opening / closing plate 508. When the stepper motor 5071 is operated by the operator, it drives the rotating shaft 5072 to rotate the opening / closing plate 508. This design enables the temporary storage cylinder 509 to connect or close with the feed inlet of the processing equipment 7, facilitating material conveying and vacuuming of the temporary storage cylinder 509. An elastic sealing ring is provided on the outer layer of the opening / closing plate, ensuring the opening and closing function of the plate and the stability of sealing the temporary storage cylinder 509, thereby ensuring the stability of the vacuum pump 501 in drawing air from the inside of the temporary storage cylinder 509 to achieve a vacuum.

[0026] like Figure 1 and Figure 2 As shown, the temporary storage cylinder 509 is fixedly mounted on the connecting plate 502, which in turn engages with two horizontal shafts 601 on the carrier 6. These two horizontal shafts 601 are firmly fixed to the carrier 6, primarily serving to help maintain the stability of the temporary storage cylinder 509. During the vacuuming process, the vibration of the temporary storage cylinder 509, combined with the elastic connection of the processing equipment 7 and the vibration characteristics of the simply supported beam of the horizontal shafts 601, effectively transmits the vibration to the counterweight 4 fixedly mounted on the temporary storage cylinder 509. Simultaneously, the connection hole 5010 and the horizontal shafts 601 further allow the temporary storage cylinder 509 to slide axially along the horizontal shafts 601, thereby further effectively reducing the irregular vibration of the lifting tube 2. This design not only enhances the vibration effect of the lifting tube 2 but also ensures the stability of the temporary storage cylinder 509 during the vacuuming process. Under the stable support of the elastic part 3, the counterweight 4 causes the lifting tube 2 to produce relatively irregular swaying. This shaking reduces the risk of blockage that may occur when powdered material enters the temporary storage cylinder 509 through the riser pipe 2 under negative pressure, and also reduces excessive friction between the powdered material and a certain point on the inner wall of the riser pipe 2. This design not only improves the material conveying efficiency but also extends the service life of the equipment.

[0027] The connecting plate 502 has a connecting hole 5010 for connecting to the horizontal shaft 601, and two insertion sleeves 504 are fixedly installed on the side of the connecting plate 502 facing the horizontal shaft 601. Insertion rods 505 are inserted into each insertion sleeve 504 to confine the horizontal shaft 601 within the connecting hole 5010, thereby stably connecting the connecting plate 502 and the horizontal shaft 601. This maintains the relative position of the temporary storage cylinder 509 while ensuring relatively stable vibration of the temporary storage cylinder 509 under the load of the horizontal shaft 601 during vacuuming. The ends of the two horizontal shafts 601 facing away from the shelf 602 are provided with baffles with an outer diameter larger than the connecting hole 5010 to further maintain the connection stability between the horizontal shaft 601 and the connecting plate 502. Two plug rods 505 are fixedly provided with a pull plate 503 at one end of the connecting plate 502, and a pull groove is provided between the pull plate 503 and the connecting plate 502 so that the operator can pull the plug rod 505 and the plug sleeve 504 as needed, thereby realizing the convenient disassembly and assembly of the connecting plate 502 and the horizontal shaft 601.

[0028] Both horizontal shafts 601 are fixedly mounted on a carrying rack 602 connected to the support frame 8. The carrying rack 602 is fixed to the support frame 8 with anchor bolts and is positioned corresponding to the feed inlet of the processing equipment 7. This design allows operators to elastically connect the bottom of the discharge port of the temporary storage cylinder 509 to the feed inlet of the processing equipment 7 using a flexible tube, thus maintaining the amplitude of vibration of the temporary storage cylinder 509 itself. The carrying rack 602 has a gantry-shaped structure, and both bends away from the support frame 8 are equipped with reinforcing ribs 603. This design maintains the structural stability of the carrying rack 602, and, based on the stability of the position of the horizontal shafts 601, makes the horizontal shafts 601 form a state similar to a simply supported beam. When the temporary storage cylinder 509 vibrates due to vacuuming or other reasons, the end of the horizontal shaft 601 away from the carrying rack 602 can generate displacement and sway within a certain range, providing the necessary conditions for the vibration of the temporary storage cylinder 509.

[0029] Specifically, the model of stepper motor 5071, the model of vacuum pump 501, the sealed rotational connection between shaft 5072 and temporary storage cylinder 509, and the control methods of stepper motor 5071 and vacuum pump 501 should all be understood as existing technology.

[0030] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
