Description

Technical Field

[0001] This utility model relates to the field of ventilation equipment technology, and more specifically, to an energy-saving and noise-reducing device for indoor ventilation equipment. Background Technology

[0002] Indoor ventilation equipment is widely used in modern buildings to ensure indoor air quality and environmental comfort. However, traditional ventilation systems often produce significant noise pollution during operation, mainly from fan vibration, airflow turbulence, and friction between air and duct walls.

[0003] Currently, common noise reduction technologies mainly focus on passive noise reduction measures, such as installing silencers, sound insulation cotton, or optimizing duct structure. However, these methods often cannot effectively solve the problem of additional noise caused by impurities in the air. Impurities form turbulent vortices in the airflow, which not only increases wind resistance and energy consumption, but also generates high-frequency noise by colliding with equipment components. Therefore, in view of this, we have studied and improved the existing structure to provide an energy-saving noise reduction device for indoor ventilation equipment, in order to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an energy-saving and noise-reducing device for indoor ventilation equipment. It can use multiple filter bags to perform initial filtration of the incoming air, so that larger particles in the air are removed. The power module is used to energize the electrostatic adsorption mechanism and accumulate charge to generate electrostatic adsorption force, so that when the air passes through the connecting pipe, the dust carried by it is adsorbed on the surface of the conductive layer, achieving the effect of removing fine dust, further reducing impurities in the air, and solving the problem of additional noise caused by impurities in the air.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] An energy-saving and noise-reducing device for indoor ventilation equipment includes a ventilation pipe one and a ventilation pipe two. An electrostatic adsorption mechanism is fixedly connected between the ventilation pipe one and the ventilation pipe two. A filter component is installed at the end of the ventilation pipe one away from the electrostatic adsorption mechanism.

[0009] The electrostatic adsorption mechanism includes a connecting pipe fixed between ventilation pipe one and ventilation pipe two. An electrode layer is fixedly connected to the inner wall of the connecting pipe, and a contact layer is fixedly connected to the inner wall of the electrode layer. A conductive layer is provided on the inner surface of the contact layer.

[0010] Furthermore, a power module is installed at the top of the connecting pipe, and the power module is electrically connected to the electrode layer via wires.

[0011] Furthermore, a ash discharge hole is provided at the bottom of the connecting pipe, and a suitable plug is inserted into the ash discharge hole.

[0012] Furthermore, electric cylinders are installed on both sides of the connecting pipe, and a connecting plate is fixedly connected between the output ends of the two electric cylinders. The top of the connecting plate is fixedly connected to the bottom of the blocking plate.

[0013] Furthermore, the filter assembly includes a mounting bracket with multiple air inlet ports on one side. A filter bag is installed at one end of each air inlet port near the ventilation duct, and one end of the filter bag extends into the ventilation duct.

[0014] Furthermore, the mounting bracket is attached to one end of the ventilation duct and fixed by clamps.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) In this solution, multiple filter bags are used to pre-filter the incoming air, so that larger particles in the air are processed. The power module is used to energize the electrostatic adsorption mechanism and accumulate charge to generate electrostatic adsorption force. When the air passes through the connecting pipe, the dust it carries is adsorbed on the surface of the conductive layer, achieving the effect of removing fine dust, further reducing impurities in the air, and solving the problem of additional noise caused by impurities in the air.

[0018] (2) In this solution, by removing the clamp, the filter bag on the mounting bracket can be removed from the ventilation pipe for cleaning. By disconnecting the electrode layer, the residual charge in the contact layer is neutralized under the action of the conductive coating, so that the accumulated dust is released quickly. The electric cylinder can be used to move the block plate down, so that the ash discharge hole is opened, and the accumulated dust can be discharged from the ash discharge hole. The whole operation is clean, convenient and quick. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0035] Example:

[0036] Please see Figures 1-4 An energy-saving and noise-reducing device for indoor ventilation equipment includes a ventilation pipe 1 and a ventilation pipe 2. An electrostatic adsorption mechanism 3 is fixedly connected between the ventilation pipe 1 and the ventilation pipe 2. A filter assembly 4 is installed at the end of the ventilation pipe 1 away from the electrostatic adsorption mechanism 3.

[0037] The electrostatic adsorption mechanism 3 includes a connecting pipe 301 fixed between ventilation duct 1 and ventilation duct 2. An electrode layer 302 is fixedly connected to the inner wall of the connecting pipe 301, and a contact layer 303 is fixedly connected to the inner wall of the electrode layer 302. A conductive layer 304 is provided on the inner surface of the contact layer 303. In use, the connecting pipe 301 can be made of insulating material, while the electrode layer 302 can include a positive electrode region, a negative electrode region, and an insulating region disposed between the positive and negative electrode regions. When an external power supply device starts to apply voltage, the insulating region between the positive and negative electrode regions becomes a capacitor region. The accumulated charge in the capacitor region generates electrostatic adsorption force, which can be used to adsorb and filter fine dust in the air. In addition, the contact layer 303 is disposed on the surface of the electrode layer 302, and its structure can prevent electrostatic breakdown and improve its overall safety.

[0038] See Figure 3 A power module 5 is installed on the top of the connecting pipe 301, and the power module 5 is electrically connected to the electrode layer 302 through wires.

[0039] See Figure 2 The bottom of the connecting pipe 301 is provided with a ash discharge hole 6, and a suitable plug plate 7 is inserted into the ash discharge hole 6.

[0040] See Figure 2 and Figure 3 Electric cylinders 8 are installed on both sides of the connecting pipe 301. A connecting plate 9 is fixedly connected between the output ends of the two electric cylinders 8. The top of the connecting plate 9 is fixedly connected to the bottom of the blocking plate 7.

[0041] See Figure 4 The filter assembly 4 includes a mounting bracket 401. Multiple air inlet ports 402 are provided on one side of the mounting bracket 401. A filter bag 403 is installed at the end of the air inlet port 402 near the ventilation duct 1. One end of the filter bag 403 extends into the ventilation duct 1.

[0042] See Figure 1 and Figure 4 The mounting bracket 401 is attached to the end of the ventilation duct 1 and fixed by clamp 10.

[0043] In operation: Air enters the ventilation system through ventilation duct 1. During entry, the air is first pre-filtered by multiple filter bags 403, which removes larger particles. The power module 5 energizes the electrode layer 302, accumulating charge and generating electrostatic attraction. When the air passes through the connecting pipe 301, the dust it carries is attracted to the surface of the conductive layer 304 due to this electrostatic attraction, achieving the effect of filtering fine dust and further reducing impurities in the air. This solves the problem of additional noise caused by impurities in the air. This greatly improves the energy-saving and noise-reduction effect of the entire ventilation equipment. When the ventilation equipment needs to be cleaned, the clamp 10 can be removed, and the filter bag 403 on its mounting bracket 401 can be removed from the ventilation pipe 1 for cleaning. Turning off the power module 5 de-energizes the electrode layer 302. Under the action of the conductive layer 304, the residual charge in the contact layer 303 is neutralized, allowing the accumulated dust to be released quickly. The electric cylinder 8 can drive the blocking plate 7 to move down, opening the ash discharge hole 6, so that the accumulated dust can be discharged from the ash discharge hole 6. The whole operation is convenient and quick to clean.
