Description

Technical Field

[0001] This utility model relates to the field of airflow classification technology, and in particular to a multi-stage series airflow classification device. Background Technology

[0002] In the field of airflow classification technology, in order to meet the needs of fine and efficient classification of materials, multi-stage series airflow classification devices have gradually become one of the mainstream application equipment due to their advantages of multi-unit collaborative sorting. Its core operating logic is to connect multiple sorting units in series so that the airflow carries the material through different classification stages in sequence, thereby achieving the gradual separation of materials of different particle sizes and improving classification accuracy and efficiency.

[0003] Chinese patent document publication number CN208303240U discloses an airflow multi-stage classifier, comprising at least two classifiers connected in series, a cyclone separator, a dust collector, and an induced draft fan arranged sequentially. Each classifier includes a housing with a feed pipe. The housing has a secondary air inlet and a lower outlet at the bottom, and an upper outlet at the top. Inside the housing is a classifying wheel connected to a power unit via a main shaft. Below the classifying wheel inside the housing is a material tray, shaped like a basin with an open top, evenly distributed micropores on the bottom surface, and inclined outwards on the sides. The material tray has a power blade. One end of the feed pipe inside the housing is located above the material tray. The airflow multi-stage classifier connects multiple classifiers in series, increasing the classification accuracy of powders. The material tray within each classifier pre-disperses the material to be classified and simultaneously pulverizes large powder particles, improving the extraction rate of fine powder.

[0004] However, the aforementioned patent documents face a series of problems caused by vibration interference during use, which cannot be addressed, severely restricting the stability and service life of the equipment. This in turn disturbs the stability of the airflow field inside adjacent units, disrupting their normal classification conditions. More importantly, this vibration transmission easily triggers the vibration superposition effect of multi-stage structures. As the vibration is transmitted and accumulated between series units, the vibration amplitude of the overall device will continuously increase. This will not only exacerbate the non-working load of the core components of the equipment, leading to faster wear rates and shorter replacement cycles for vulnerable parts, but may also cause the equipment connection structure to loosen and seals to fail due to long-term high-frequency vibration, resulting in airflow leakage and directly affecting the classification accuracy. Therefore, we propose a multi-stage series airflow classification device to solve the above problems. Utility Model Content

[0005] The main objective of this invention is to provide a multi-stage series airflow grading device that can effectively solve the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A multi-stage series airflow classification device includes an installation assembly, wherein a plurality of vibration damping components are installed in the inner cavity of the installation assembly, a sorting component is installed on the upper part of each of the plurality of vibration damping components, and an airflow component is installed on the upper part of each of the plurality of sorting components.

[0008] Preferably, the mounting assembly includes a support frame, and a plurality of fixed shells are installed in the inner cavity of the support frame.

[0009] Preferably, the vibration damping component includes several mounting brackets, all of which are installed in the inner cavity of the support frame. A T-shaped slider is installed on the upper right side of each of the mounting brackets, and several fixed shells are installed on the upper left side of each of the mounting brackets. A damper is installed in the inner cavity of the several fixed shells located on the same side and in the inner cavity of the several fixed shells located on the same side.

[0010] Preferably, the sorting component includes a plurality of airflow separator bodies, each of the plurality of airflow separator bodies being mounted on the upper center of a plurality of mounting frames, and each of the plurality of airflow separator bodies having a discharge pipe mounted on the lower center of a plurality of airflow separator bodies.

[0011] Preferably, the airflow assembly includes several diverter pipes, all of which are installed at the upper center of the airflow separator body located in the same part. A manifold is installed at the lower end of the several diverter pipes. A valve is installed on the outer surface of the manifold located on the right side. Two fixed flanges are installed at the lower end of the manifold.

[0012] Preferably, the top wall of the inner cavity of the support frame is provided with a plurality of sliding grooves, and the plurality of T-shaped sliders are installed in the sliding grooves located on the same side.

[0013] Preferably, each of the several airflow separator bodies has a placement hole from top to bottom, and the lower parts of the several airflow separator bodies form a curved surface.

[0014] Preferably, both of the fixed flanges are fixed to the plane by expansion bolts.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This device achieves vibration reduction during use through its designed installation and vibration damping components. The core feature of the multi-stage series airflow classification device is that multiple units are connected in series. During operation, vibrations can easily interfere with other devices in the series, thereby disturbing the airflow in other devices. This leads to the superposition of vibrations in the multi-stage structure, increasing the vibration amplitude and reducing the lifespan of the equipment. At the same time, the damper dissipates vibration energy and can quickly attenuate the transmission of vibrations at each stage, avoiding resonance. When the device's operating frequency is close to the structure's natural frequency, the damper can widen the resonance avoidance range of the device, preventing misalignment, sealing failure, or even structural cracking in the multi-stage structure due to resonance. Furthermore, the component displacement caused by vibration can damage the fit of the seals. By stabilizing the vibration of the device body, the damper can reduce the non-working load on the core components and lower the wear rate. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example 1, as Figures 1-5 As shown, a multi-stage series airflow classification device includes an installation component 1, a plurality of vibration damping components 2 are installed in the inner cavity of the installation component 1, a sorting component 3 is installed on the upper part of each plurality of vibration damping components 2, and an airflow component 4 is installed on the upper part of each plurality of sorting components 3.

[0025] When implementing this solution, the operator first installs the device on a flat surface. When the air pump is connected to the airflow assembly 4, and the operator needs to separate dust, the operator first pumps the gas dust into the airflow assembly 4. Then the gas will pass through the airflow assembly 4 and enter the sorting assembly 3, thereby achieving the effect of cross-flow sorting and achieving the effect of multi-stage sorting.

[0026] When the sorting component 3 is sorting, it will vibrate. The simultaneous vibration of multiple sorting components 3 will cause resonance, which will lead to an increase in the vibration amplitude. At this time, the vibration damping component 2 will absorb the vibration, so that the vibration will disappear at the beginning and avoid serious damage to the equipment parts due to excessive vibration amplitude.

[0027] Specifically, in order to perform airflow sorting, such as Figure 3 As shown, in this scheme, the sorting component 3 includes several airflow separator bodies 31, which are all installed at the upper center of several mounting frames 21, and each of the airflow separator bodies 31 has a discharge pipe 32 installed at the lower center.

[0028] For further details, please refer to [link / reference]. Figure 2 The airflow assembly 4 includes several diversion pipes 44, which are all installed at the upper center of the airflow separator body 31 located in the same part. The lower ends of the several diversion pipes 44 are connected to a common manifold 42. A valve 43 is installed on the outer surface of the manifold 42 located on the right side, and two fixed flanges 41 are installed at the lower end of the manifold 42.

[0029] For further details, please refer to [link / reference]. Figure 3 Each of the airflow separator bodies 31 has a placement hole from top to bottom, and the lower part of the airflow separator bodies 31 forms a curved surface.

[0030] For further details, please refer to [link / reference]. Figure 2 Both fixed flanges 41 are fixed to the plane by expansion bolts.

[0031] When implementing this solution, the operator first installs the device on a flat surface and connects the air pump to the manifold 42. Then, when the operator needs to separate dust, the operator first pumps the gas dust into the manifold 42. The gas then passes through the manifold 42 and the diversion pipe 44 into the airflow separator body 31, thereby achieving the effect of cross-flow separation and multi-stage separation.

[0032] Meanwhile, when it is necessary to temporarily stop the sorting process, the operator can turn valve 43 to close the manifold 42, thereby achieving the effect of temporary cessation.

[0033] Example 2, which is based on Example 1, can reduce vibration during use.

[0034] Specifically, in order to reduce vibration during use, such as Figure 4 As shown, in this scheme, the installation component 1 includes a support frame 11, and a plurality of fixed shells 12 are installed in the inner cavity of the support frame 11.

[0035] For further details, please refer to [link / reference]. Figure 4 and Figure 5 The vibration damping component 2 includes several mounting brackets 21, all of which are installed in the inner cavity of the support frame 11. T-shaped sliders 22 are installed on the upper right side of each of the mounting brackets 21, and several fixed shells 23 are installed on the upper left side of each of the mounting brackets 21. The inner cavities of the fixed shells 23 on the same side and the inner cavities of the fixed shells 12 on the same side are jointly equipped with dampers 24.

[0036] For further details, please refer to [link / reference]. Figure 2 box Figure 5 The inner wall of the support frame 11 is provided with several sliding grooves, and several T-shaped sliders 22 are installed in the sliding grooves on the same side.

[0037] When this solution is implemented, the air classifier body 31 will vibrate when it is performing sorting. The simultaneous vibration of multiple air classifier bodies 31 will cause vibration resonance, which will lead to an increase in vibration amplitude. At this time, the fixed shell 23 will slide to absorb the vibration and make the vibration disappear at the beginning, thereby avoiding excessive vibration amplitude that could cause serious damage to equipment parts.

[0038] At the same time, when absorbing vibration, the T-shaped slider 22 will drive the mounting bracket 21 to slide, allowing the fixed shell 23 to slide and absorb vibration.

[0039] After the final sorting is completed, the dust will be discharged from the discharge pipe 32;

[0040] The airflow separator body 31 in this embodiment is an airflow separator in the prior art, and the model of the airflow separator is: MSS type.

[0041] In summary, the implementation process of this utility model is as follows:

[0042] The operator first installs the device on a flat surface and connects the air pump to the manifold 42. When the operator needs to separate dust, the operator first pumps the gas dust into the manifold 42. Then the gas will pass through the manifold 42 and the diversion pipe 44 into the airflow separator body 31, thereby achieving the effect of cross-flow separation and achieving the effect of multi-stage separation.

[0043] When the airflow separator body 31 is performing sorting, the airflow separator body 31 will vibrate. The simultaneous vibration of multiple airflow separator bodies 31 will cause vibration resonance, which will lead to an increase in vibration amplitude. At this time, the fixed shell 23 will slide to absorb the vibration and make the vibration disappear at the beginning, thereby avoiding excessive vibration amplitude that could cause serious damage to the equipment parts.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
