Description

Technical Field

[0001] This utility model belongs to the technical field of jade processing equipment, specifically relating to a dust removal device for jade processing. Background Technology

[0002] Since ancient times, exquisitely crafted jade has always been one of the most precious and important ornaments in people's hearts. With the continuous development of society and the improvement of people's living standards, jade ornaments have gradually entered every household.

[0003] To obtain a shape that matches the material and color of jade, it is usually necessary to cut, grind, carve, and polish the jade. During the entire jade processing process, a large amount of dust is inevitably generated, which pollutes the environment and affects the health of practitioners.

[0004] In the jade processing industry, liquid pouring is commonly used to reduce dust generated during production. Although the dust removal effect is good, for some processes, such as grinding and polishing of finished product surfaces, the limitations of equipment and other objective factors still require the use of negative pressure dust collection to deal with dust issues.

[0005] Currently, pulse-jet baghouse dust collectors with related pipelines have become the mainstream solution for negative pressure dust removal. While this solution offers excellent dust removal performance and convenient maintenance, the large size of pulse-jet baghouse dust collectors makes them unsuitable for small processing areas with limited space (generally referring to spaces with a ceiling height of 3.5 to 5 meters). Other existing negative pressure dust removal solutions that meet these space requirements, such as those using dust removal devices with the same structure as those disclosed in CN211029632U ​​or CN214419229U, both rely on direct filtration using filter screens. However, some dust enters the filter screen and cannot be effectively cleaned, often resulting in poor dust removal performance and high maintenance difficulty during continuous operation. Summary of the Invention

[0006] To address the shortcomings of the existing technology, this utility model provides a dust removal device for jade processing. By cleverly designing the structure and position of the inlet component, settling box, and lower pipe, and by respectively setting a first guide part and a second guide part, the overall volume and height are reduced while ensuring excellent filtration effect, making it suitable for working environments in small processing areas.

[0007] The technical effects to be achieved by this utility model are realized through the following technical aspects: This utility model provides a dust removal device for jade processing, including a settling component, a fan, and a filter component; The settling assembly includes an inlet component, a settling box, and a lower pipe. The inlet component has a hollow cylindrical structure, including a first cavity and an external port extending outward in a direction tangential to the inlet component, the external port communicating with the first cavity. The settling box is eccentrically located at the lower end of the inlet component and includes a second cavity communicating with the first cavity. The lower pipe passes through the inlet component and communicates with the second cavity, including an intake end disposed within the second cavity and a power end extending out of the top of the inlet component. The power end is connected to one side of the fan, and the filter assembly is fixedly connected to the other side of the fan.

[0008] In the vertical direction, the first cavity and the second cavity are respectively provided with a spiral first guide part and a second guide part, which are fixed to the inlet component and the inner wall of the settling tank, respectively.

[0009] In some implementations, the fan is an axial flow fan, and the fan operates vertically upwards; the outer diameter of the inlet component is larger than the outer diameter of the settling tank.

[0010] In some implementations, the spiral directions of the first guide portion and the second guide portion are opposite.

[0011] Furthermore, the first guide portion is multi-headed spiral, and the second guide portion can be single-headed or multi-headed spiral, with the vertical tilt angle of the first guide portion being greater than or equal to 30°.

[0012] In some implementations, the lower pipe is coaxially arranged with the settling tank, and the suction end is located at the bottom of the second guide, with its diameter gradually decreasing in the direction close to the second guide.

[0013] In some implementations, the diameter of the power end gradually increases in the direction away from the inlet member, and the largest end is connected to the fan.

[0014] In some implementations, the bottom of the settling tank has a funnel-shaped structure, and the suction end is located at the position of the funnel-shaped structure; the settling tank is provided with a collection box, which is located at the bottom of the funnel-shaped structure.

[0015] In some implementations, the filtration assembly includes a conduit and a filter bag, one end of the conduit is connected to the fan, and the other end is fitted with and fixed to the filter bag; the conduit is configured in an inverted U-shape.

[0016] In some implementations, an external connection component is also included, which includes a pipe module and a dust hood. The pipe module is connected to the external port and extends outward away from the inlet component. The dust hood is disposed on the pipe module and includes an inlet end facing the jade processing workbench and communicating its working space with the inside of the pipe module.

[0017] In some implementations, a low-frequency vibrator is provided on the outer surface of the inlet or settling tank, and the low-frequency vibrator is located near the outside of the first guide or the second guide.

[0018] In summary, this utility model has at least the following advantages: 1. The jade processing dust removal device provided by this utility model generates a negative pressure effect through a fan. Dust enters through the external port, passes sequentially through the inlet component and the settling box. Under the influence of the first and second guide parts, larger dust particles fall into the settling box, while the remaining finer dust particles enter the lower pipe through the suction end and are finally completely filtered by the filter assembly. Compared with existing small dust removal devices, its filtration effect is excellent and fully meets the dust removal requirements of jade processing.

[0019] 2. The jade processing dust removal device provided by this utility model, through the ingenious setting of the structure and position of each component of the settling component, makes the entire jade processing dust removal device compact, smaller in size and lower in height, while ensuring excellent filtration effect, and is more suitable for working environments in small processing areas below 5 meters.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0035] For ease of understanding, it should be noted that the Z-axis direction is the vertical direction.

[0036] Example 1: Please see Figures 1-3 As shown, this embodiment provides a jade processing dust removal device 100, which is mainly installed near the indoor jade processing area of ​​a small jade processing plant to filter and settle the dust 301 generated during the jade processing process, thereby reducing the dust 301 content in the indoor environment, especially in the closed processing space during summer.

[0037] The jade processing dust removal device 100 includes a settling component 1, a fan 2, and a filter component 3. The settling component 1 settles larger dust particles in the dust 301 to reduce the filtration volume of the filter component 3. The fan 2 is located between the settling component 1 and the filter component 3, providing negative pressure to draw finer dust 301 towards the filter component 3, thereby filtering the remaining dust 301.

[0038] Specifically, the settling assembly 1 includes an inlet component 11, a settling box 12, and a lower pipe 13. The inlet component 11 has a hollow cylindrical structure, including a first cavity 111 and an external port 112 extending outward in a direction tangential to the inlet component 11, which communicates with the first cavity 111. The settling box 12 is eccentrically located at the lower end of the inlet component 11 in the vertical direction Z, and includes a second cavity 121 communicating with the first cavity 111. The lower pipe 13 passes through the inlet component 11 and communicates with the second cavity 121, including an intake end 131 disposed in the second cavity 121 and a power end 132 extending out of the top of the inlet component 11. The power end 132 is connected to one side of the fan 2, and the filter assembly 3 is fixedly connected to the other side of the fan 2.

[0039] Along the vertical direction Z, the first cavity 111 and the second cavity 121 are respectively provided with a spiral first guide part 113 and a second guide part 122, which are respectively fixed to the inlet part 11 and the inner wall of the settling box 12.

[0040] Please Figures 1-3 Based on this, refer to Figure 4 . Figure 4 The dotted line with arrows indicates the airflow direction. During use, the settling assembly 1, fan 2, and filter assembly 3 are tightly connected, except for the external connection port 112, which is a sealed connection. The external connection port 112 connects to an external pipe, thus enabling spatial connection between the jade processing dust removal device 100 and each jade processing workbench.

[0041] When the fan 2 starts, a negative pressure space is formed in the settling assembly 1 at the lower end of the fan 2, causing the external port 112 to draw in a gas mixture 300 containing dust 301 into the first cavity 111. In this embodiment, the cylindrical structure of the inlet member 11 has a smaller dimension in the vertical Z direction to reduce the overall height and achieve the required airflow effect. The external port 112, which is tangentially positioned, allows the gas mixture 300 to swirl and flow along the outer wall of the first cavity 111 after entering the inlet member 11. When the gas mixture 300 enters the first cavity 111, it is slowed down by the spiral-shaped first guide part 113, and larger dust particles 301 begin to separate and settle.

[0042] The gas mixture 300 continues to be affected by negative pressure as it enters the second chamber 121. The spiral-shaped second guide 122 further increases the flow resistance of the gas mixture 300, while also increasing its settling path. Larger dust particles 301 gradually settle onto the surface of the second guide 122 due to the decreased flow velocity. During settling, the gas mixture 300 also pushes the dust particles 301 that have already settled on the surface of the second guide 122 further into the bottom of the settling tank 12, thereby achieving the effect of separation and settling.

[0043] It should be noted that the eccentric arrangement of the settling box 12 and the inlet component 11 results in inconsistent flow velocities of the gas mixture 300 at different points in the first cavity 111. This creates varying degrees of turbulence as it flows toward the upper part of the second cavity 121, ensuring that the gas mixture 300 receives sufficient resistance and improving the settling ratio.

[0044] When the gas mixture 300 reaches the suction end 131, it has essentially settled. The remaining dust particles 301 are smaller and lighter, and not easily settled, so they continue to flow towards the fan 2 through the suction end 131. After passing through the fan 2, the filter assembly 3 filters the remaining finer dust particles 301, completing the air purification. The specific dust removal efficiency varies depending on the filter material used.

[0045] A gas mixture 300 containing dust 301 enters the jade processing dust removal device 100 through the external port 112. After the aforementioned settling and filtration, it fully meets the dust removal requirements for jade processing. Compared to existing small dust removal devices, its filtration effect is excellent. A lower pipe 13 passes through the inlet 11 and the settling box 12, and a first guide 113 and a second guide 122 are provided. While effectively completing settling and filtration, the structure is compact and small in size. In the vertical direction Z, through design and selection, its height can be controlled to below 3 meters, fully meeting the working environment of small processing areas below 5 meters.

[0046] In this embodiment, to meet the functional and height requirements of the jade processing dust removal device 100, the fan 2 is an axial flow fan, and the working direction of the fan 2 is vertically upward. The large flow rate and compact mechanical structure of the axial flow fan are more suitable for the dust removal environment described in this embodiment, and its economic efficiency is also suitable for micro and small enterprises whose main production sites are small processing areas.

[0047] In addition, the outer diameter of the inlet 11 should be larger than the outer diameter of the settling box 12. When the gas mixture 300 enters the first cavity 111, in addition to being affected by the first guide part 113, the gas mixture 300 is also affected by the increase in negative pressure space, and the airflow deceleration effect is more obvious. Since the outer diameter of the settling box 12 is smaller than that of the inlet 11, it is used to accelerate the gas mixture 300 again during the initial settling process to prevent excessive deposition of dust 301 at the bottom of the inlet 11.

[0048] In a further embodiment, the spiral directions of the first guide portion 113 and the second guide portion 122 are opposite. When the gas mixture 300 carrying dust 301 passes through the junction of the first guide portion 113 and the second guide portion 122, due to the opposite spiral directions, it is affected by the inertia of the dust 301, causing the dust 301 to separate from the air more rapidly, thus increasing the settling ratio of the dust 301.

[0049] Furthermore, the first guide section 113 is multi-headed spiral, and the second guide section 122 can be single-headed or multi-headed spiral. The vertical Z-angle of the first guide section 113 is greater than or equal to 30°. Since the outer diameter of the inlet 11 is larger than the outer diameter of the settling tank 12, after the gas mixture 300 enters the inlet 11 through the external port 112, the wind resistance of the multi-headed spiral first guide section 113 will increase as the flow velocity decreases. In practical applications, a vertical Z-angle of the first guide section 113 greater than or equal to 30° can achieve a more ideal settling effect. The gas mixture 300 "spins" in the inlet 11, where coarser dust 301 can settle in large quantities and then be carried along the second guide section 122 into the settling tank 12.

[0050] The second guide section 122 can also adopt a multi-head spiral structure to improve settling. However, since a large amount of coarse dust 301 is deposited at the bottom of the second guide section 122, the multi-head spiral structure of the second guide section 122 may blow up the dust 301 at the bottom when the flow rate of the gas mixture 300 is high. Therefore, in this embodiment, the second guide section 122 adopts a single-head spiral shape. The gas mixture 300 rotates and flows within the second guide section 122, and the dust 301 will gradually move away from the center, achieving separation from the airflow. At the same time, it increases the settling distance of the gas mixture 300 in the second guide section 122, ensuring sufficient settling.

[0051] Continue reading Figures 1-4 To improve the separation of dust 301 and prevent it from being re-inhaled into the lower pipe 13, the lower pipe 13 is coaxially arranged with the settling box 12, and the suction end 131 is located at the bottom of the second guide 122. After being coaxially arranged, the suction end 131 is located in the middle of the bottom of the settling box 12. A large amount of coarser dust 301 undergoes centrifugal motion in the second guide 122, thereby moving away from the suction end 131 to avoid being sucked in.

[0052] Please Figures 1-4 Based on the above Figure 5a and Figure 5b ,like Figure 5a As shown, the diameter of the suction end 131 gradually decreases along the direction close to the second guide part 122, so that the flow rate of the suction end 131 gradually increases from bottom to top. Since the suction force of the suction end 131 is small at the opening, it avoids the coarser dust 301 falling nearby from being sucked into the lower pipe 13, while the finer dust 301, because it cannot settle, continues to be sucked into the lower pipe 13 by the suction end 131, and finally reaches the filter assembly 3.

[0053] Furthermore, the suction force of the lower duct 13 is determined by the fan 2. To maximize the utilization of the suction force and airflow of the fan 2, such as... Figure 5b As shown, the diameter of the power end 132 gradually increases in the direction away from the inlet member 11, and the largest end is connected to the fan 2.

[0054] Of course, to facilitate collection after settling, the bottom of the settling tank 12 is designed in a funnel shape, with the suction end 131 located at the funnel-shaped structure. The settling tank 12 is equipped with a collection box 123, which is located at the bottom of the funnel-shaped structure. Coarser dust 301 is collected into the collection box 123 by the funnel-shaped structure. After a period of use, the collection box 123 can be pulled out for cleaning.

[0055] In this embodiment, please continue to refer to Figures 1-5b The filter assembly 3 includes a conduit 31 and a filter bag 32. One end of the conduit 31 is connected to the fan 2, and the other end is fitted with and fixed to the filter bag 32. The filter bag 32 is a commonly used filter consumable in the dust filtration industry, and its filtration effect meets the requirements of jade processing scenarios. By directly connecting the conduit 31 and the filter bag 32 to the fan 2, the difficulty and cost of later maintenance of the jade processing dust removal device 100 can be effectively reduced. In order to reduce the overall height and facilitate the fixing operation of the filter bag 32, the conduit 31 is set with an inverted U-shaped structure.

[0056] Of course, in other embodiments, the filter assembly 3 can also be implemented as a plate filter box. Multiple plate-shaped filter screens are installed in the filter box. When the gas mixture 300 enters the filter box and passes through the filter screens, finer dust particles 301 adhere to the screens, achieving the effect of air filtration. This solution is quite common and will not be described in detail here.

[0057] In summary, the jade processing dust removal device provided by this utility model utilizes a negative pressure effect generated by a fan. Dust enters through the external port, passes sequentially through the inlet component and the settling box, and, influenced by the first and second guide parts, larger dust particles fall into the settling box, while the remaining finer dust particles enter the lower pipe through the suction end and are ultimately completely filtered by the filter assembly. Compared to existing small dust removal devices, its filtration effect is excellent, fully meeting the dust removal requirements of jade processing.

[0058] Secondly, by cleverly setting the structure and position of each component of the settling assembly, the entire jade processing dust removal device is made compact, smaller in size and lower in height, while ensuring excellent filtration effect, making it more suitable for working environments in small processing areas below 5 meters.

[0059] Example 2: This embodiment provides a dust removal device 100 for jade processing, which is structurally optimized based on Embodiment 1. Please refer to the following description. Figures 1-5b Based on this, refer to Figures 6-7The jade processing dust removal device 100 differs from Embodiment 1 in that it further includes an external connection component 4. The external connection component 4 includes a pipe module 41 and a dust collection hood 42. The pipe module 41 is connected to an external port 112 and extends outwards away from the inlet component 11. The dust collection hood 42 is mounted on the pipe module 41 and includes an inlet end 421 facing the jade processing workbench 200, and its working space is connected to the interior of the pipe module 41.

[0060] When the fan 2 operates and generates negative pressure at the external port 112, the dust suction hood 42 installed on the pipe module 41 generates a certain suction force to adsorb the dust 301 generated during jade processing. The dust 301 enters the pipe module 41 through the dust suction hood 42, and then enters the inlet component 11 and other structures through the external port 112 for sedimentation and filtration, thus completing the filtration of the dust 301.

[0061] To improve the negative pressure within the pipe module 41, prevent insufficient suction, and reduce the amount of dust drawn in, sealing gaskets 15 are installed at the connections between the pipe module 41, dust hood 42, etc., and the number of dust hoods 42 should be controlled to no more than four. The pipe module 41 can also be manufactured using a modular splicing method to meet the needs of production lines with different lengths and dimensions.

[0062] Of course, to achieve a good negative pressure effect, a structure similar to a one-way valve can be installed between the pipe module 41 and the dust hood 42 to avoid negative pressure leakage. Alternatively, a negative pressure boosting device can be added inside the pipe module 41 to further ensure the suction effect. Since adding related equipment or structures will also increase related costs and maintenance difficulty, specific settings and adjustments need to be made according to actual needs, which will not be elaborated here.

[0063] With the external connection component 4, a set of jade processing dust removal device 100 can serve multiple jade processing workstations, meeting the indoor processing needs of micro and small jade processing enterprises.

[0064] Example 3: This embodiment, based on Embodiments 1 and 2, proposes a dust removal device 100 for jade processing. Please refer to the following: Figures 1-7 On the basis of, participate Figures 8-9 The difference between this embodiment and embodiments 1 and 2 is that a low-frequency vibrator 14 is provided on the outer surface of the inlet component 11 or the settling box 12, and the low-frequency vibrator 14 is located near the outer side of the first guide part 113 or the second guide part 122.

[0065] During production and manufacturing, both the inlet component 11 and the settling tank 12 are made of metal to meet the overall strength and rigidity requirements. During actual settling, the gas mixture 300 drawn in under negative pressure will generate significant friction with the thin metal wall, resulting in electrostatic adsorption. Electrostatic adsorption plays a role in separating dust 301, but considering the different electrostatic adsorption conditions, excessive dust 301 should be prevented from adhering tightly to the first guide portion 113 and the second guide portion 122 due to electrostatic adsorption. By installing a low-frequency vibrator 14 on the outer surface of the inlet component 11 or the settling tank 12, the dust 301 is gradually lowered or moved downwards through intermittent vibration. This facilitates the subsequent collection and sorting of dust 301. In this embodiment, the low-frequency vibrator 14 is located on the outside of the settling tank 12.

[0066] However, in other embodiments, assembly defects are sometimes created to induce vibration in the fan 2, resulting in low-frequency vibrations. However, this method can negatively impact welds and connection structures, leading to problems such as weld cracking and connection detachment later on.

[0067] In addition, to ensure overall stability, a fixed bracket 5 can be installed at the lower end of the inlet component 11 in the vertical Z direction. The fixed bracket 5 is made of conductive metal, which is equivalent to a grounding wire to discharge static electricity. During installation, in order to reduce the impact of static electricity on sedimentation and filtration during operation, which could lead to difficulties in subsequent dust cleaning, and also to prevent accidental electric shock to personnel touching the outer casing, a grounding wire 16 is connected to the lower end of the first guide part 113 and the second guide part 122 in the vertical Z direction to achieve electrical grounding.

[0068] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
