Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of pharmaceutical equipment, particularly to a dust removal device. BACKGROUND

[0002] In the production line of vials or similar products, the feeding of aluminum caps usually adopts the automatic arrangement of a vibrating hopper. This method uses a high-frequency vibrator to generate oscillation, causing the aluminum caps to displace within the hopper, thereby achieving automatic feeding. However, this feeding method has some significant defects.

[0003] Firstly, since a large number of aluminum caps are placed inside the hopper, during high-frequency oscillation, intense friction occurs between the aluminum caps and between the aluminum caps and the surface of the hopper. This friction generates a large number of 2-10 μm suspended particles and larger aluminum chips. As the number of aluminum caps continues to increase, these aluminum chips and particles continue to accumulate, with the quantity increasing.

[0004] Secondly, the bottom of the existing vibrating hopper is usually a complete closed surface, lacking an effective chip removal mechanism. This results in aluminum chips being unable to be promptly removed, but instead adhering to the surface of the aluminum caps. When the aluminum caps are transferred to the bottle opening, these adhered aluminum chips are also transferred, directly affecting the quality and safety of the product.

[0005] More seriously, the large number of suspended particles accumulated inside the hopper will spread in all directions under the action of air percussion. This spreading phenomenon seriously damages the A-level cleanliness requirement in the production environment, possibly leading to product contamination and quality problems.

[0006] In addition, the existing vibrating hopper dust removal device often lacks an effective multi-stage dust removal mechanism. A single dust removal method is difficult to deal with particles of different sizes and properties, resulting in poor dust removal effect. At the same time, the existing device usually lacks a flexible control mechanism, and cannot adjust the dust removal intensity and frequency according to actual production needs.

[0007] Finally, the existing dust removal device often ignores the structural compatibility with the vibrating hopper in design, which may affect the normal conveying and arrangement of the aluminum caps, thereby reducing production efficiency.

[0008] In view of the above problems, a dust removal device is proposed. UTILITY MODEL CONTENT

[0035] The dust removal device of this utility model will now be described in more detail with reference to the accompanying drawings, which illustrate preferred embodiments of the utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the utility model.

[0036] In the description of this specification, terms such as "one embodiment" or "some embodiments" mean that one or more embodiments of this specification include a particular feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0037] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0038] The dust removal device according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0039] This utility model proposes a dust removal device, such as Figure 1 As shown, it includes: a base 1, a vibrating hopper 2, a first dust removal module 3 and a second dust removal module 4. The vibrating hopper 2 is installed on the base 1. The dust removal port of the first dust removal module 3 is directly opposite the feed port of the vibrating hopper 2. The bottom plate of the vibrating hopper 2 is provided with a plurality of through holes 8. The second dust removal module 4 is installed between the vibrating hopper 2 and the base 1 and is provided corresponding to the plurality of through holes 8.

[0040] The base 1 refers to the basic structure used to support the entire dust removal device, which can be implemented using a platform made of metal materials.

[0041] The vibrating hopper 2 refers to a container used to hold and transport aluminum caps, which can be implemented using a funnel-shaped structure with a vibration mechanism.

[0042] The first dust removal module 3 refers to the dust removal device installed at the feed inlet of the vibrating hopper 2, which can be implemented by a dust collection device or an electrostatic dust removal device.

[0043] The second dust removal module 4 refers to a dust removal device arranged at the bottom of the vibrating hopper 2, and can be implemented by using a negative pressure dust removal system.

[0044] The core innovation of the utility model lies in designing a double dust removal system. Two dust removal modules are arranged at the feeding port and the bottom of the vibrating hopper 2 respectively, forming a comprehensive dust removal scheme. The first dust removal module 3 can start dust removal when the aluminum cover enters the hopper, reducing the dust entering the hopper and cleaning the flying dust. The second dust removal module 4 can process the dust generated during the vibration, which will fall through the through hole 8 on the bottom plate and be adsorbed. This design can effectively reduce the particle amount in the vibrating hopper 2, solving the problem of high particle amount in the vibrating hopper 2 of the aluminum cover.

[0045] The working principle of the utility model is as follows:

[0046] The base 1 is the basis of the whole device, made of solid metal material, with sufficient strength and stability to support the vibrating hopper 2 and other components. The vibrating hopper 2 is installed on the base 1 and connected with the base 1 by fixing bolts or welding, ensuring that it will not displace during work.

[0047] The vibrating hopper 2 adopts a funnel structure, with a vibrating mechanism inside, which can produce high-frequency vibration to make the aluminum cover displace in the hopper. The bottom plate of the vibrating hopper 2 is provided with a plurality of through holes 8, the diameter of which is smaller than the size of the aluminum cover, but sufficient to allow dust and small particles to pass through.

[0048] The first dust removal module 3 is installed above the vibrating hopper 2, with its dust removal port facing the feeding port of the vibrating hopper 2. This arrangement can start dust removal when the aluminum cover enters the hopper, reducing the dust entering the hopper and cleaning the flying dust generated. The first dust removal module 3 can use a dust collector or an electrostatic precipitator, and the appropriate dust removal method can be selected according to actual needs.

[0049] The second dust removal module 4 is installed between the vibrating hopper 2 and the base 1, corresponding to the plurality of through holes 8 on the bottom plate of the vibrating hopper 2. This arrangement can process the dust generated during the vibration, which will fall through the through hole 8 on the bottom plate and be adsorbed by the second dust removal module 4. The second dust removal module 4 can use a negative pressure dust removal system to adsorb the falling dust and particles by generating negative pressure.

[0050] When the aluminum cover enters the feeding port of the vibrating hopper 2, the first dust removal module 3 will immediately start working to adsorb the dust on the surface of the aluminum cover and in the surrounding air. Subsequently, the aluminum cover moves inside the vibrating hopper 2, and in this process, new dust is generated due to friction. These newly generated dust and the previously incompletely removed dust will fall into the second dust removal module 4 through the through holes 8 on the bottom plate under the action of vibration. The second dust removal module 4 continuously works to continuously adsorb the falling dust.

[0051] The design of this double dust removal system can effectively reduce the particle amount in the vibrating hopper 2. The first dust removal module 3 reduces the initial dust amount entering the hopper, and the second dust removal module 4 continuously processes the dust generated during vibration, both of which work together to form a comprehensive dust removal solution.

[0052] In some embodiments of the utility model, as shown in Figure 1 、 Figure 2 It also includes a bracket 7, which is installed on the outer contour of the base 1 and the vibrating hopper 2, and the first dust removal module 3 is installed on the bracket 7.

[0053] The utility model introduces the technical feature of the bracket 7, which is installed on the outer contour of the base 1 and the vibrating hopper 2, providing a mounting position for the first dust removal module 3. This design enables the first dust removal module 3 to be stably installed in the appropriate position to effectively remove dust from the material in the vibrating hopper 2.

[0054] By installing the bracket 7 on the outer contour of the base 1 and the vibrating hopper 2 and installing the first dust removal module 3 on the bracket 7, the problem of the installation position of the first dust removal module 3 is solved. This design not only provides a stable mounting structure, but also ensures that the first dust removal module 3 can be correctly aligned with the feeding port of the vibrating hopper 2, thereby achieving efficient dust removal effect. The introduction of the bracket 7 enhances the structural stability of the entire device, and also facilitates the installation, maintenance and adjustment of the first dust removal module 3.

[0055] Specifically, the bracket 7 can be implemented in various forms to achieve its function. For example, the bracket 7 can be designed as a frame structure composed of multiple connecting rods, which can be made of metal materials or high-strength engineering plastics. The bottom of the bracket 7 can be fixed on the base 1 by bolts or welding, and the top can be designed to closely fit the shape of the outer contour of the vibrating hopper 2. This design not only provides stable support, but also can adapt to vibrating hoppers 2 of different sizes and shapes.

[0056] Further, the support 7 can be provided with multiple mounting points or slots for fixing the first dust removal module 3. These mounting points or slots can be designed to be adjustable, allowing the position and angle of the first dust removal module 3 to be adjusted within a certain range. In this way, the dust removal port of the first dust removal module 3 can be accurately aligned with the feed port of the vibrating hopper 2, ensuring optimal dust removal effect.

[0057] The introduction of the support 7 forms an integrated structure with the first dust removal module 3 and the vibrating hopper 2. This coordination in structure not only solves the problem of installation position, but also brings additional benefits. For example, through reasonable design of the support 7, the distance between the first dust removal module 3 and the vibrating hopper 2 can be optimized, ensuring dust removal effect without interfering with the normal operation of the vibrating hopper 2. In addition, the presence of the support 7 can also provide installation space for other additional equipment (such as control panels, sensors, etc.), further improving the functionality and flexibility of the entire device.

[0058] In actual application, the design of the support 7 needs to consider multiple factors. First, the material selection of the support 7 should consider both strength and weight to ensure stability while not excessively increasing the weight of the entire device. Second, the structural design of the support 7 should consider the vibration generated during the operation of the vibrating hopper 2, and appropriate vibration reduction measures should be taken, such as using vibration reduction pads or elastic connectors, to prevent vibration from being transmitted to the first dust removal module 3, affecting its working effect. Finally, the surface treatment of the support 7 also needs to be considered, and corrosion-resistant coatings or corrosion-resistant materials can be used to adapt to different working environments.

[0059] As a preferred embodiment, the support 7 can be designed as a detachable modular structure. This design allows the support 7 to be quickly replaced or adjusted according to different sizes and shapes of the vibrating hopper 2, improving the adaptability and maintenance convenience of the device. For example, the support 7 can be composed of multiple standardized connectors that can be quickly assembled and disassembled through bolts or buckles, etc. This not only facilitates transportation and installation, but also leaves room for future upgrades or modifications.

[0060] This design of the support 7 not only can stably support the first dust removal module 3, but also can effectively reduce the influence of vibration on the dust removal effect. By adjusting the position of the mounting hole, the relative position of the first dust removal module 3 and the feed port of the vibrating hopper 2 can be accurately controlled, thereby optimizing the dust removal effect. At the same time, the modular design makes the installation, maintenance and replacement of the entire device more convenient, greatly improving production efficiency.

[0061] Compared with the prior art, the utility model discloses a support 7 structure is introduced, effectively solved the installation problem of the first dust removal module 3. Traditional dust removal device often installs the dust removal module directly on the vibrating hopper 2 or adopts independent support structure, these methods either influence normal work of vibrating hopper 2, either difficult accurate positioning dust removal module. The support 7 design of the utility model not only provides stable mounting position, also realizes the structure coordination with vibrating hopper 2, neither influence vibrating hopper 2's work, can ensure the best working position of dust removal module. In addition, the support 7 design of the utility model has higher flexibility and adjustability, can adapt to different models vibrating hopper 2 and dust removal module, greatly improve the versatility and practicality of device.

[0062] In some embodiments of the utility model, as shown in Figure 1 、 Figure 2 、 Figure 5 The first dust removal module 3 includes a plurality of suction needles 30 and a plurality of first pipelines 5, a plurality of the suction needles 30 are connected with a plurality of the first pipelines 5 correspondingly, and the suction needles 30 are arranged opposite to the feed inlet and close to the bottom plate of the vibrating hopper 2.

[0063] The design of the first dust removal module 3 adopts a combination of a plurality of the suction needles 30 and a plurality of the first pipelines 5. A plurality of the suction needles 30 are connected with a plurality of the first pipelines 5 correspondingly to form a plurality of independent dust removal channels. This design increases the coverage area and efficiency of dust removal. The suction needles 30 are arranged opposite to the feed inlet, which can start dust removal at the first time when the aluminum cover enters the hopper, effectively reducing the chance of dust and aluminum scraps entering the hopper.

[0064] The suction needles 30 are arranged close to the bottom plate of the vibrating hopper 2, which has two main advantages. First, since a large amount of dust and aluminum scraps will be generated during the vibration of the aluminum cover, these particulate matters will settle to the bottom under the action of gravity, but part of the particulate matters will float in the vibrating hopper 2, and the suction needles 30 can remove the floating particulate matters, and the settled particulate matters are cleaned by the second dust removal module 4 through the through holes 8 to achieve complete cleaning of the vibrating hopper 2. Second, the position close to the bottom plate is usually an area where the aluminum cover accumulates more, and dusting here can better clean the dust attached to the surface of the aluminum cover.

[0065] Further, the number and layout of the suction needles 30 can be adjusted according to actual needs. For example, a plurality of the suction needles 30 can be evenly distributed around the feed inlet to form a ring-shaped dust removal area. This layout can ensure effective dust removal regardless of the direction of the aluminum cover entering the hopper.

[0066] The connection mode of the suction needle 30 and the first pipeline 5 can also be optimized according to actual conditions. For example, a quick disassembly connection mode can be adopted to facilitate cleaning and maintenance. In addition, the material of the first pipeline 5 can be selected as an antistatic material to prevent static electricity from being generated during dust removal, thereby affecting the dust removal effect.

[0067] The dust removal device of the utility model realizes all-round dust removal of the aluminum cover by setting dust removal structures at the feeding port and the bottom of the vibrating hopper 2. This design not only removes dust as soon as the aluminum cover enters the hopper, but also continuously removes dust and aluminum scraps generated due to vibration in the hopper, effectively solving the problem of excessive particle amount in the vibrating hopper 2.

[0068] Specifically, when the aluminum cover enters the vibrating hopper 2, the suction needle 30 located at the feeding port immediately starts to work and adsorbs dust and aluminum scraps on the surface of the aluminum cover. Since the suction needle 30 is close to the bottom plate of the vibrating hopper 2, they can continuously remove new dust and aluminum scraps generated due to vibration. Multiple suction needles 30 are connected to multiple first pipelines 5 correspondingly to form multiple independent dust removal channels. This design increases the coverage area and efficiency of dust removal and ensures the continuity and comprehensiveness of the dust removal process.

[0069] Meanwhile, multiple through holes 8 provided on the bottom plate of the vibrating hopper 2 cooperate with the second dust removal module 4 to further enhance the dust removal effect inside the hopper. This double dust removal structure not only ensures the timeliness of dust removal, but also ensures the continuity and comprehensiveness of dust removal, significantly improving the dust removal effect.

[0070] As a preferred embodiment, the suction needle 30 can be designed as an adjustable angle structure. For example, the suction needle 30 can be connected to the first pipeline 5 through a spherical joint, so that the angle of the suction needle 30 can be adjusted according to actual needs to adapt to aluminum covers of different shapes and sizes. Different size ranges can ensure sufficient suction force without damaging the aluminum cover. In addition, a microporous structure can be provided on the surface of the suction needle 30 to increase the adsorption area.

[0071] In actual application, the number of suction needles 30 is set to 2, 3, 4, 5, 6 or more, and the number of suction needles 30 can be set according to the size and shape of the vibrating hopper 2, which will not be described here. These suction needles 30 can be evenly distributed around the feeding port to form a circular dust removal area. Each suction needle 30 is connected to a negative pressure device through an independent first pipeline 5. The negative pressure device provides negative pressure, so that the suction needle 30 can adsorb dust and aluminum scraps without affecting the normal conveying of the aluminum cover.

[0072] The dust removal device has remarkable advantages compared with the prior art. In the prior art, the vibrating hopper 2 is usually designed with a closed bottom, which cannot effectively discharge the accumulated dust and aluminum scraps. However, the dust removal device of the utility model realizes omnibearing and continuous dust removal by arranging the suction needle 30 at the feeding port and arranging the through hole 8 and the second dust removal module 4 at the bottom. This design not only reduces the entry of dust and aluminum scraps at the source, but also continuously removes the dust and aluminum scraps generated in the hopper, effectively solving the problem of dust and aluminum scrap accumulation in the prior art.

[0073] In addition, the dust removal device forms multiple independent dust removal channels through the multiple suction needles 30 and the multiple first pipelines 5, greatly improving the dust removal efficiency. Compared with the single dust removal port design, this design can more comprehensively and efficiently remove dust and aluminum scraps, significantly reducing the particle amount in the hopper.

[0074] In some embodiments of the utility model, as shown in Figure 5 The suction groove 301 is arranged on the suction needle 30, and the suction groove 301 is arranged along the extension direction of the suction needle 30. A plurality of suction holes 302 are arranged in the suction groove 301.

[0075] The suction needle 30 is an important component of the first dust removal module 3 and is used for adsorbing dust and particles in the vibrating hopper 2. The suction groove 301 arranged on the suction needle 30 can increase the adsorption area and improve the adsorption efficiency. The suction groove 301 is arranged along the extension direction of the suction needle 30, which can ensure that the suction groove 301 covers the entire length of the suction needle 30 and maximizes the use of the surface area of the suction needle 30.

[0076] A plurality of suction holes 302 are arranged in the suction groove 301 and arranged along the suction groove 301, which can further increase the adsorption area and adsorption effect. The arrangement of the plurality of suction holes 302 can form a larger negative pressure area and improve the adsorption capacity of dust and particles. At the same time, the distribution of the plurality of suction holes 302 can ensure the uniformity of the adsorption effect and avoid the occurrence of adsorption dead angles.

[0077] Through this design, the adsorption effect of the suction needle 30 is significantly improved, which can more effectively remove dust and particles in the vibrating hopper 2, thereby solving the technical problem of poor adsorption effect of the suction needle 30. This improvement not only improves the working efficiency of the dust removal device, but also helps to maintain the cleanliness of the production environment, which is of great significance to ensure product quality.

[0078] Specifically, the design of the adsorption groove 301 can have multiple implementations. For example, the adsorption groove 301 can be a linear groove along the length direction of the suction needle 30, or a spiral groove. The linear groove can provide uniform adsorption effect, while the spiral groove can increase the adsorption area. The depth of the adsorption groove 301 can be adjusted according to actual needs. Further, the cross section of the adsorption groove 301 is designed as a V-shaped, thereby avoiding the aluminum cover from blocking the adsorption groove 301, ensuring the dust removal effect while avoiding affecting the production.

[0079] The design of the adsorption hole 302 can also have multiple variations. The adsorption hole 302 can be circular, oval or other shapes. The hole diameter can be determined according to the size of the dust particles to be adsorbed. The arrangement of the adsorption hole 302 can also be flexibly adjusted, which can be single column arrangement or multi-column staggered arrangement, to improve the adsorption efficiency.

[0080] The material selection of the suction needle 30, the adsorption groove 301 and the adsorption hole 302 is also important. Generally, corrosion-resistant and easy-to-clean materials such as stainless steel and aluminum alloy can be selected. This not only ensures the stability of long-term use, but also facilitates daily maintenance and cleaning.

[0081] In addition, the design of the adsorption groove 301 on the suction needle 30 interacts positively with other parts of the first dust removal module 3. The arrangement of the adsorption groove 301 and the adsorption hole 302 increases the connection area with the first pipeline 5, so that the suction force generated by the negative pressure device can be more evenly and effectively distributed on the surface of the suction needle 30. This design not only improves the adsorption efficiency of a single suction needle 30, but also optimizes the working performance of the entire first dust removal module 3.

[0082] The utility model discloses a plurality of adsorption holes 302 are arranged on the suction needle 30, which not only improves the adsorption efficiency, but also solves the problem that the traditional suction needle 30 is easy to have adsorption dead angle. The uniform distribution of multiple adsorption holes 302 ensures the uniform distribution of adsorption force on the surface of the entire suction needle 30, greatly reducing the possibility of dust and particle residue. In addition, this design also reduces the risk of the suction needle 30 being blocked, because even if part of the adsorption hole 302 is blocked, other adsorption holes 302 can still work, ensuring the continuity and stability of the dust removal effect.

[0083] Compared with the prior art, the design has obvious advantages. The traditional suction needle 30 usually adopts a smooth surface design, although simple to manufacture, but the adsorption effect is limited. The utility model discloses a plurality of adsorption grooves 301 and a plurality of adsorption holes 302 are arranged on the surface of the suction needle 30, the effective adsorption area is significantly increased, and a stronger negative pressure area is formed. This design not only improves the adsorption efficiency, but also enhances the adaptability to different size particles. At the same time, the design of the utility model is also convenient for cleaning and maintenance, and the accumulated material in the adsorption groove 301 and the adsorption hole 302 can be removed by reverse airflow flushing, prolonging the service life of the equipment.

[0084] In some embodiments of the utility model, as shown in Figure 2 、 Figure 4 The second dust removal module 4 includes a gas distribution disc 40, the gas distribution disc 40 is installed between the vibrating hopper 2 and the base 1, and a plurality of air holes 9 are arranged on the gas distribution disc 40, and the plurality of air holes 9 are arranged correspondingly with the through holes 8.

[0085] The gas distribution disc 40 of the second dust removal module 4 is installed between the vibrating hopper 2 and the base 1, and a plurality of air holes 9 are arranged on the gas distribution disc 40, and the plurality of air holes 9 are arranged correspondingly with the through holes 8 on the bottom plate of the vibrating hopper 2. The structure design makes the second dust removal module 4 can effectively remove dust at the bottom of the vibrating hopper 2.

[0086] By arranging the gas distribution disc 40 at the bottom of the vibrating hopper 2 and arranging the air holes 9 on the gas distribution disc 40 correspondingly with the through holes 8 on the bottom plate of the vibrating hopper 2, effective dust removal at the bottom of the vibrating hopper 2 can be realized. When the vibrating hopper 2 works, the dust and particles generated at the bottom can be sucked away through the through holes 8 of the bottom plate and the air holes 9 of the gas distribution disc 40, so as to achieve the purpose of dust removal. This design not only solves the problem of dust removal at the bottom of the vibrating hopper 2, but also prevents dust and particles from accumulating in the hopper, improves the dust removal efficiency and effect.

[0087] Specifically, the design of the gas distribution disc 40 can have various implementation manners. For example, the gas distribution disc 40 can adopt a circular, square or other geometric shape suitable for the shape of the bottom of the vibrating hopper 2. The material of the gas distribution disc 40 can be selected from metal, plastic or other wear-resistant materials to ensure the stability during long-term use. The number, size and distribution of the air holes 9 can be adjusted according to actual needs to achieve the best dust removal effect.

[0088] The installation mode between the air distribution plate 40 and the bottom plate of the vibrating hopper 2 can also be various. Bolt fixing, buckle connection or other detachable connection modes can be adopted to facilitate daily maintenance and cleaning. In addition, a sealing ring or gasket can be added between the air distribution plate 40 and the base 1 to prevent dust from leaking from the gap.

[0089] The corresponding arrangement of the air vent 9 and the through hole 8 on the bottom plate of the vibrating hopper 2 is the key of the design. The corresponding arrangement can be one-to-one accurate correspondence or staggered correspondence, as long as the dust and particles can be smoothly sucked away through the two layers of holes. The shape of the air vent 9 can be circular, oval or other suitable shapes, and the hole diameter can be designed according to actual needs.

[0090] The technical scheme of the utility model adds the air distribution plate 40 at the bottom of the vibrating hopper 2, forming a double-layer filtering structure. The through hole 8 on the bottom plate of the vibrating hopper 2 serves as the first layer of filtering, and the air vent 9 on the air distribution plate 40 serves as the second layer of filtering. The double-layer structure not only improves the dust removal efficiency, but also prevents large particle impurities from directly entering the dust removal system, prolonging the service life of the dust removal equipment.

[0091] In actual application, when the vibrating hopper 2 is working, the dust and particles generated by the friction between the aluminum covers and the surface of the hopper will move to the bottom under the action of gravity and vibration. These dust and particles first pass through the through hole 8 on the bottom plate of the vibrating hopper 2, and then pass through the air vent 9 on the air distribution plate 40, and finally are sucked away by the dust removal system connected below the air distribution plate 40. This layer-by-layer filtering method greatly improves the dust removal effect and effectively solves the technical problem of dust removal at the bottom of the vibrating hopper 2.

[0092] Through this design, the utility model can effectively solve the problem of dust removal at the bottom of the vibrating hopper 2. Compared with the prior art, the utility model has the following advantages: first, by adding the air distribution plate 40 at the bottom of the vibrating hopper 2, a double-layer filtering structure is formed, which greatly improves the dust removal efficiency; second, the design of the air distribution plate 40 makes the bottom of the vibrating hopper 2 no longer completely closed, solving the problem of unable to remove dust in the prior art; finally, through effective bottom dust removal, the accumulation of aluminum scraps and dust in the hopper is reduced, the risk of product pollution is reduced, and the problem of suspended particles spreading to the surrounding is also reduced, which helps to maintain the cleanliness of the production environment.

[0093] In some embodiments of the utility model, as shown in Figure 2As shown, the base 1 is provided with through holes (not shown), and the second dust removal module 4 further comprises a plurality of second pipelines 6, which are arranged in the through holes to communicate with the air holes 9.

[0094] The technical scheme of the utility model realizes the close connection between the second dust removal module 4 and the base 1 by arranging the through holes on the base 1 and making the second pipelines 6 pass through the through holes to connect the air holes 9. This design enables the second dust removal module 4 to be stably installed between the vibrating hopper 2 and the base 1, while ensuring the effective realization of the dust removal function.

[0095] Specifically, the base 1 is provided with a plurality of through holes, which can be designed according to actual needs, such as circular, elliptical or other suitable shapes. The number and distribution of the through holes can be optimized according to the structure and dust removal needs of the second dust removal module 4. The second pipelines 6 can be made of flexible materials, such as hoses or bellows, to facilitate passing through the through holes of the base 1 and connecting with the air holes 9.

[0096] The diameter of the second pipeline 6 can be designed according to the dust removal needs and the thickness of the base 1. The length of the second pipeline 6 needs to consider the distance from the bottom of the base 1 to the air hole 9. In order to improve the stability and sealing of the connection, the connection between the second pipeline 6 and the through hole can be sealed with a sealing ring or sealing glue.

[0097] In addition, the connection mode of the second pipeline 6 and the air hole 9 can also be optimized. For example, a flange or threaded interface can be provided at the end of the second pipeline 6 to reliably connect with the air hole 9. Through this design, not only the stability of the connection can be ensured, but also the maintenance and replacement in the later stage are facilitated.

[0098] The utility model realizes the close connection between the second dust removal module 4 and the base 1 by arranging the through holes on the base 1 and making the second pipelines 6 pass through the through holes to connect the air holes 9. This design enables the second dust removal module 4 to be stably installed between the vibrating hopper 2 and the base 1, while ensuring the effective realization of the dust removal function.

[0099] Specifically, when the vibrating hopper 2 is working, the dust and particles generated at the bottom will fall onto the air distribution plate 40 of the second dust removal module 4 through the through hole 8. The air holes 9 on the air distribution plate 40 are connected with the second pipeline 6, and the dust and particles can be effectively sucked away through the action of the negative pressure device. Since the second pipeline 6 passes through the through hole of the base 1, the entire dust removal system forms a closed circulation, greatly improving the dust removal efficiency.

[0100] As a preferred embodiment, the base 1 can be made of a metal material, such as stainless steel or aluminum alloy, to ensure sufficient strength and stability. The second pipeline 6 can be a polyurethane hose. The air distribution plate 40 can be a perforated plate structure, and the material can be stainless steel or engineering plastic.

[0101] Through this design, the dust removal device of the utility model can effectively solve the dust removal problem at the bottom of the vibrating hopper 2. Compared with the traditional dust removal scheme only above the hopper, the technical scheme of the utility model increases the second dust removal module 4 at the bottom and ingeniously realizes the connection by using the structure of the base 1, greatly improving the comprehensiveness and efficiency of dust removal. This design not only effectively removes the dust and particles generated during the vibration process, but also prevents these pollutants from re-entering the hopper or scattering into the environment, thereby significantly improving the cleanliness of the production environment.

[0102] Compared with the prior art, the technical scheme of the utility model has the following advantages: first, by providing the through hole on the base 1 and making the second pipeline 6 pass through, the second dust removal module 4 is tightly connected with the base 1, improving the stability of the overall structure. Secondly, this design makes the dust removal system form a closed circulation, greatly improving the dust removal efficiency. Thirdly, the technical scheme of the utility model can simultaneously solve the dust removal problem above and at the bottom of the vibrating hopper 2, realizing the all-around dust removal effect. Finally, this design ingeniously uses the structure of the base 1, realizing the optimization and improvement of the function without increasing the overall volume of the device.

[0103] In some embodiments of the utility model, a negative pressure device (not shown in the figure) is further included, which is communicated with the first pipeline 5 and the second pipeline 6.

[0104] In the existing penicillin bottle or similar product production line, the aluminum cover adopts the automatic arrangement feeding mode of the vibration hopper 2. Although this mode can realize automatic feeding, when the inside of the hopper is filled with a large number of aluminum covers, the aluminum covers are rubbed against each other and the surface of the hopper under high-frequency oscillation, a large number of 2-10 μm suspended particles and large aluminum chips are generated. With the continuous increase of the number of aluminum covers, the number of aluminum chips and particles will accumulate more and more, and since the bottom of the hopper is a complete closed surface, it cannot remove the chips. These aluminum chips will adhere to the surface of the aluminum cover and be transferred to the bottle opening with the aluminum cover, affecting the product. At the same time, a large number of suspended particles accumulated in the hopper spread in all directions under the forced vibration of the air, seriously damaging the A-level environment.

[0105] The dust removal device of the utility model discloses a base 1, vibration hopper 2, first dust removal module 3, second dust removal module 4 and negative pressure device. The vibration hopper 2 is installed on the base 1, and the dust removal port of the first dust removal module 3 is opposite the feed inlet of the vibration hopper 2. A plurality of through holes 8 are arranged on the bottom plate of the vibration hopper 2, and the second dust removal module 4 is installed between the vibration hopper 2 and the base 1 and corresponds to the plurality of through holes 8. The first dust removal module 3 includes a plurality of suction needles 30 and a plurality of first pipelines 5, and the plurality of suction needles 30 are connected with the plurality of first pipelines 5, the suction needle 30 is opposite the feed inlet and is close to the bottom plate of the vibration hopper 2. The second dust removal module 4 includes the air distribution disc 40, which is installed between the vibration hopper 2 and the base 1, and a plurality of air holes 9 are arranged on the air distribution disc 40, and the plurality of air holes 9 correspond to the through holes 8. The base 1 is provided with the via, and the second dust removal module 4 further includes a plurality of second pipelines 6, and the plurality of second pipelines 6 are arranged in the via and communicate with the plurality of air holes 9. The negative pressure device communicates with the first pipeline 5 and the second pipeline 6.

[0106] The utility model discloses a base 1, vibration hopper 2, first dust removal module 3, second dust removal module 4 and negative pressure device. The vibration hopper 2 is installed on the base 1, and the dust removal port of the first dust removal module 3 is opposite the feed inlet of the vibration hopper 2. A plurality of through holes 8 are arranged on the bottom plate of the vibration hopper 2, and the second dust removal module 4 is installed between the vibration hopper 2 and the base 1 and corresponds to the plurality of through holes 8. The first dust removal module 3 includes a plurality of suction needles 30 and a plurality of first pipelines 5, and the plurality of suction needles 30 are connected with the plurality of first pipelines 5, the suction needle 30 is opposite the feed inlet and is close to the bottom plate of the vibration hopper 2. The second dust removal module 4 includes the air distribution disc 40, which is installed between the vibration hopper 2 and the base 1, and a plurality of air holes 9 are arranged on the air distribution disc 40, and the plurality of air holes 9 correspond to the through holes 8. The base 1 is provided with the via, and the second dust removal module 4 further includes a plurality of second pipelines 6, and the plurality of second pipelines 6 are arranged in the via and communicate with the plurality of air holes 9. The negative pressure device communicates with the first pipeline 5 and the second pipeline 6.

[0107] Further, the negative pressure device can be provided as a negative pressure fan. The use of the negative pressure fan can provide a stable negative pressure source, ensuring the consistency and reliability of the dust removal effect. Therefore, the dust removal device of the utility model can more effectively reduce the dust content in the vibration hopper 2 and improve the dust removal efficiency.

[0108] As a preferred embodiment, a plurality of said air holes 9 are arranged in a circumferential array on said air distribution plate 40, the number of groups of said air holes 9 arranged in an array is the same as the number of said suction needles 30, and said first pipeline 5 and said second pipeline 6 are connected in communication, said first pipeline 5 is connected in communication with a negative pressure device. This arrangement can ensure the uniformity of the dust removal coverage and improve the dust removal efficiency.

[0109] Compared with the prior art, the dust removal device of the utility model simultaneously connects said first pipeline 5 and said second pipeline 6 through a negative pressure device, realizing double dust removal of the feeding port and the bottom plate of said vibrating hopper 2. This design not only effectively removes the dust generated during the feeding process, but also removes the dust and aluminum scraps accumulated inside the hopper through said through hole 8 of the bottom plate. Thus, the dust removal device of the utility model solves the problem of ineffective removal of dust accumulated inside the hopper in the prior art, significantly improves the dust removal efficiency, and effectively protects the production environment.

[0110] In some embodiments of the utility model, said negative pressure device is set as a negative pressure fan.

[0111] The negative pressure device is an important component of the dust removal device, which is used to provide negative pressure to realize the dust removal function. The negative pressure device connects said first pipeline 5 and said second pipeline 6 to provide power for the entire dust removal system.

[0112] By setting the negative pressure device as a negative pressure fan, negative pressure can be effectively generated to realize dust removal of the interior and surrounding space of said vibrating hopper 2. As a common negative pressure equipment, the negative pressure fan has the advantages of simple structure, easy operation and maintenance. It can continuously and stably generate negative pressure to ensure the continuity and reliability of the dust removal effect.

[0113] The use of negative pressure fan makes the entire dust removal system work more efficiently. It is connected to different parts of the dust removal device through said first pipeline 5 and said second pipeline 6, which can simultaneously remove dust from the feeding port and the bottom said through hole 8 of said vibrating hopper 2. This design not only effectively removes dust and particles on the surface of the aluminum cover, but also prevents dust from spreading to the environment through the bottom said through hole 8, thereby maintaining the cleanliness of the production environment.

[0114] Specifically, the negative pressure fan can adopt various types, such as centrifugal negative pressure fan or axial flow negative pressure fan. The centrifugal negative pressure fan generates centrifugal force through the high-speed rotating impeller to suck air from the inlet and discharge it from the outlet, thereby generating negative pressure. The axial flow negative pressure fan transports air along the axial direction through the axial rotating blades, which also can generate negative pressure effect.

[0115] Further, the selection of the negative pressure fan can be customized according to the specific needs of the dust removal device. For example, a negative pressure fan with an air volume in the range of 500-2000 m 3 / h and a negative pressure in the range of 5-20 kPa can be selected. Such parameter ranges can meet the needs of most aluminum cover vibration hopper 2 dust removal devices. Among them, the actual parameter selection of the negative pressure fan is set according to the actual needs in the production process, which will not be repeated here.

[0116] Therefore, the negative pressure fan forms a complete dust removal system with the first dust removal module 3 and the second dust removal module 4. The negative pressure fan is connected to the suction needle 30 of the first dust removal module 3 through the first pipeline 5, and is connected to the air distribution disc 40 of the second dust removal module 4 through the second pipeline 6. This connection mode enables the negative pressure fan to provide negative pressure power to both dust removal modules at the same time, achieving comprehensive dust removal of the feed inlet and the through hole 8 at the bottom of the vibration hopper 2.

[0117] As a preferred embodiment, the negative pressure fan can be installed on one side or the bottom of the base 1 to save space and reduce the impact on the production line layout. The air inlet of the negative pressure fan can be connected to the first pipeline 5 and the second pipeline 6 through a hose or a hard pipe to ensure smooth air flow transmission. At the same time, a filter can be installed at the connection between the negative pressure fan and the pipeline to prevent dust from entering the fan and prolong the service life of the equipment.

[0118] By using a negative pressure fan as a negative pressure device, the dust removal device of the present application has significant advantages in solving the problem of particle quantity in the aluminum cover vibration hopper 2. Compared with traditional positive pressure blowing or simple suction methods, the negative pressure fan can provide a more powerful and stable negative pressure source. This not only improves the dust removal efficiency, but also better controls the spread of dust.

[0119] Specifically, the use of a negative pressure fan enables the dust removal device of the present application to simultaneously and efficiently remove dust from the feed inlet and the through hole 8 at the bottom of the vibration hopper 2. This all-round dust removal method significantly reduces the amount of dust adhering to the surface of the aluminum cover, reducing the amount of suspended particles and aluminum chips generated by friction of the aluminum cover. At the same time, since the negative pressure fan can continuously and stably provide negative pressure, it avoids the intermittent or uneven dust removal problems that may occur in traditional dust removal methods, ensuring the consistency and reliability of the dust removal effect.

[0120] In addition, the use of a negative pressure fan also simplifies the structure of the entire dust removal system. Compared with a complex system that requires multiple independent air sources, a single negative pressure fan can provide power to the entire dust removal device, reducing the complexity and maintenance cost of the system. This not only improves the reliability of the equipment, but also facilitates daily maintenance and management by operators.

[0121] Generally, the negative pressure device is set as a negative pressure fan, which is a simple and effective technical solution, and solves the problem of how to realize a stable and reliable negative pressure source, providing necessary power support for the normal operation of the entire dust removal device. This design helps to improve the dust removal efficiency, reduce the particle amount in the vibrating hopper 2 of the aluminum cover, and thus improve the product quality and production environment.

[0122] In some embodiments of the present application, as shown in Figure 3 , Figure 4 a plurality of air holes 9 are arranged in an array on the air distribution disc 40, each suction needle 30 is connected to the same group of air holes 9, and the first pipeline 5 is connected to the second pipeline 6.

[0123] The technical scheme of the present application effectively solves the problem of excessive particle amount in the vibrating hopper 2 of the aluminum cover by arranging a plurality of air holes 9 in an array on the air distribution disc 40, connecting each suction needle 30 to the same group of air holes 9, and connecting the first pipeline 5 to the second pipeline 6 and the negative pressure device.

[0124] Specifically, the air holes 9 on the air distribution disc 40 are arranged in an array, which ensures comprehensive coverage of the bottom of the vibrating hopper 2. Each suction needle 30 is connected to the same group of air holes 9, which ensures the balance and efficiency of the dust removal system. For example, if there are 8 suction needles 30, the air holes 9 can be arranged in 8 groups, and each suction needle 30 is connected to a group of air holes 9; for example, if there are 4 suction needles 30, the air holes 9 can be arranged in 12 groups, and each suction needle 30 is connected to three groups of air holes 9, each group can contain multiple air holes 9, forming a complete circumferential arrangement.

[0125] The connection of the first pipeline 5 and the second pipeline 6, and the connection of the first pipeline 5 and the negative pressure device, forms a complete negative pressure circulation system. This connection allows the negative pressure device to generate continuous negative pressure through the second pipeline 6 and the first pipeline 5, so that the suction needles 30 and the air holes 9 can effectively adsorb and collect dust and particulate matter in the vibrating hopper 2. Further, the design of this negative pressure circulation system can adjust the negative pressure intensity according to actual needs, for example, a frequency converter can be installed on the negative pressure device to adjust the negative pressure size according to the amount of particles in the hopper, thereby achieving more precise dust removal effect.

[0126] Therefore, the technical scheme of the utility model has obvious advantages compared with the prior art. The conventional dust removal mode of the vibrating hopper 2 usually only sets a dust suction device above the hopper, which cannot effectively handle the dust accumulated at the bottom of the hopper. The utility model sets the air holes 9 arranged in a circumferential array at the bottom of the hopper and forms a corresponding relationship with the suction needles 30 above, which greatly improves the dust removal efficiency at the bottom of the hopper. At the same time, the design of the negative pressure circulation system ensures the continuity and stability of the dust removal process, avoiding the problem of dust dispersion again caused by intermittent dust removal in the conventional method. This design not only improves the dust removal efficiency, but also significantly improves the product quality and production environment, effectively solving the problem of dust accumulation in the vibrating hopper 2 in the prior art.

[0127] The technical scheme of the utility model has obvious advantages compared with the prior art. The conventional dust removal mode of the vibrating hopper 2 usually only sets a dust suction device above the hopper, which cannot effectively handle the dust accumulated at the bottom of the hopper. The utility model sets the air holes 9 arranged in a circumferential array at the bottom of the hopper and forms a corresponding relationship with the suction needles 30 above, which greatly improves the dust removal efficiency at the bottom of the hopper. At the same time, the design of the negative pressure circulation system ensures the continuity and stability of the dust removal process, avoiding the problem of dust dispersion again caused by intermittent dust removal in the conventional method. This design not only improves the dust removal efficiency, but also significantly improves the product quality and production environment, effectively solving the problem of dust accumulation in the vibrating hopper 2 in the prior art.

[0128] In some embodiments of the utility model, a plurality of electromagnetic valves (not shown in the figure) are further included, and the plurality of electromagnetic valves are correspondingly installed on the plurality of first pipelines 5 and close to the negative pressure device.

[0129] The technical scheme of the utility model realizes accurate control of the dust removal system by installing the electromagnetic valve on the first pipeline 5 and setting it close to the negative pressure device. The electromagnetic valve can open or close a specific first pipeline 5 as needed, thereby controlling the adsorption strength of the corresponding air hole 9. This design enables the dust removal device to target different areas of dust in the vibrating hopper 2 for targeted dust removal, improving the dust removal efficiency. At the same time, the setting of the electromagnetic valve also increases the flexibility of the system, and the operator can adjust the dust removal strategy according to the actual situation to adapt to different working environments and requirements.

[0130] Specifically, the technical scheme of the utility model includes the following key features:

[0131] 1. A plurality of electromagnetic valves: the electromagnetic valve is an automatic device for controlling the flow of gas or liquid, which can open or close the flow path as needed. The number of electromagnetic valves can be configured according to the number of first pipelines 5, for example, one electromagnetic valve can be configured for each first pipeline 5, or the electromagnetic valve can be configured for part of the second pipeline 6 as needed.

[0132] 2. The installation position of the electromagnetic valve: the electromagnetic valve is installed on the first pipeline 5 and is close to the negative pressure device. This installation position can maximize the loss of air flow in the pipeline and improve the control accuracy. The electromagnetic valve can be installed near the connection between the first pipeline 5 and the negative pressure device, for example, within a range of 10-30 cm from the connection.

[0133] 3. Control system: in order to fully play the role of the electromagnetic valve, the utility model can also be equipped with a corresponding control system. The control system can control the on-off state of each electromagnetic valve according to the preset program or real-time monitoring data. For example, a timing switch mode can be set, or the on-off of the electromagnetic valve can be dynamically adjusted according to the feedback of the dust concentration sensor.

[0134] The correlation and interaction between these features are as follows: the installation position of the electromagnetic valve close to the negative pressure device can ensure that the negative pressure can act on the corresponding air hole 9 quickly and effectively when the electromagnetic valve is opened. At the same time, the setting of multiple electromagnetic valves enables the system to finely control the dust removal needs of different areas. The control system coordinates the working state of each electromagnetic valve to realize the intelligent operation of the entire dust removal device. Further, in order to obtain better suction effect, when one valve is opened and the other three are disconnected, the connection time and sequence of the electromagnetic valve can form a cyclic dust collection effect, which can also avoid fixing the aluminum cover in one position to block the operation of the aluminum cover, so that the structure of the vibrating hopper 2 loses its original function.

[0135] The technical scheme of the utility model solves the problem of how to further improve the dust removal efficiency and system flexibility, and the specific working principle is as follows:

[0136] Firstly, the control system sets the working mode of each electromagnetic valve. For example, different dust removal intensities and frequencies can be set according to the dust accumulation in different areas of the vibrating hopper 2. For areas with more dust, the opening time or frequency of the corresponding electromagnetic valve can be increased; for areas with less dust, the dust removal intensity can be appropriately reduced to save energy.

[0137] Secondly, during the dust removal process, the electromagnetic valve is opened and closed according to the preset program or real-time feedback. When the electromagnetic valve is opened, the negative pressure generated by the negative pressure device directly acts on the corresponding air hole 9 through the second pipeline 6, realizing efficient dust removal of the specific area. When the electromagnetic valve is closed, the connection between the negative pressure and the air hole 9 is cut off, and the dust removal operation in that area is stopped.

[0138] Through this fine control, the technical scheme of the utility model can realize the following advantages:

[0139] 1. Improve dust removal efficiency: by targeted control of dust removal intensity in different areas, dust particles in the vibrating hopper 2 can be more effectively removed, reducing dust accumulation.

[0140] 2. Enhance system flexibility: operators can adjust the dust removal strategy at any time according to actual production needs, adapting to different working environments and requirements.

[0141] 3. Optimize energy use: by precisely controlling the working state of each air hole 9, unnecessary energy consumption is avoided, improving the working efficiency of the entire dust removal device.

[0142] 4. Prolong equipment life: by reasonably distributing the working load of the negative pressure device, long-term overuse of certain areas can be avoided, thereby prolonging the service life of the entire dust removal device.

[0143] As a preferred embodiment, as shown in Figures 1-5 the dust removal device of the utility model can be implemented as follows:

[0144] In the dust removal device of the embodiment of the utility model, the base 1 is fixed on the machine table, the upper part of the base 1 is fixedly connected with the lower end of the vibrating hopper 2, excitation is generated by vibrating the high-frequency vibrator inside the base 1, the vibrating hopper 2 is driven to vibrate at high speed, and aluminum cover screening and feeding are completed.

[0145] Preferably, under the premise of meeting the feeding, 12 groups of through holes 8 are reasonably arranged on the inner bottom surface of the vibrating hopper 2, correspondingly, the bottom of the vibrating hopper 2 is in contact and connection with the upper surface of the array type circulating air distribution disc 40, and the upper surface of the array type circulating air distribution disc 40 also has 12 groups of air holes 9 which are in one-to-one correspondence with the 12 groups of through holes 8 on the vibrating hopper 2; wherein the multiple air holes 9 of each group of the array type circulating air distribution disc 40 are mutually penetrated, and one interface is arranged for the second pipeline 6 at the center position of the lower surface of the array type circulating air distribution disc 40 corresponding to each group. The lower surface of the circulating air distribution disc 40 is in contact and connection with the base 1.

[0146] Preferably, the needle holder is fixedly connected with the vibrating base 1, the suction needle 30 module 3 is fixedly connected with the needle holder 6, and the first dust removal module 3 is located above the cavity of the vibrating hopper 2. Further, a plurality of adsorption holes 302 are opened on the surface of each suction needle 30 of the first dust removal module 3, a large number of dynamic suspended particles are sucked away by the negative pressure formed around the adsorption holes 302 during work, in addition, V-shaped grooves are opened on the outer surface of each individual suction needle 30, and the planar body cannot completely block the adsorption holes 302, which can prevent aluminum covers from being adsorbed at the adsorption holes 302.

[0147] Preferably, the pipe one 51 of the second pipe 6 is used to connect the air holes 9 of the first group 401, the fifth group 405 and the ninth group 409 on the air distribution disc 40 in array circulation with the suction needle one 31 on the first dust removal module 3; the pipe two 52 is used to connect the air holes 9 of the second group 402, the sixth group 406 and the tenth group 410 on the air distribution disc 40 in array circulation with the suction needle two 32 on the first dust removal module 3; the pipe three 53 is used to connect the air holes 9 of the third group 403, the seventh group 407 and the eleventh group 411 on the air distribution disc 40 in array circulation with the suction needle three 33 on the first dust removal module 3; the pipe four 54 is used to connect the air holes 9 of the fourth group 404, the eighth group 408 and the twelfth group 412 on the air distribution disc 40 in array circulation with the suction needle four 34 on the first dust removal module 3, forming a wide-angle circulation array, greatly expanding the coverage range.

[0148] By association, the pipe one 51, the pipe two 52, the pipe three 53 and the pipe four 54 of the first pipe 5 are all connected with the negative pressure fan, and a breakable electromagnetic valve is arranged in the middle of the first pipe 5, so that the opening and closing of the electromagnetic valve can realize the breakage and connection of the pipe. When the electromagnetic valve is opened, the pipe is connected, and the air holes 9 at the bottom of the vibrating hopper 2 and the suction holes 302 on the first dust removal module 3 generate suction force, so as to suck away the aluminum scraps and suspended particles.

[0149] Further, in order to obtain better suction effect, when one valve is opened and the other three valves are disconnected, the connection time and connection sequence of the electromagnetic valve can form a regular dust collection effect, and can also avoid the problem that the aluminum cover is fixed at the position of the suction force and blocks the running of the aluminum cover, so that the structure of the vibrating hopper 2 loses the original function.
