Description

TECHNICAL FIELD

[0002] Current charging piles generally use filter cotton and a few shaped air ducts as dustproof and waterproof solutions, however, these designs have exposed many defects in practical application. The design of a few shaped air ducts often has difficulty in effectively blocking the penetration of water when the fan is running, resulting in that the inside of the charging pile is easily affected by water, which not only may affect the normal operation of the equipment, but also may bring safety hazards. In addition, the a few shaped air duct structure is complex, which increases the air resistance, so that the charging pile needs to consume more energy when running, causing unnecessary waste. Although the filter cotton plays a role in filtering dust to some extent, its service life is limited and needs to be replaced regularly, which undoubtedly increases the operating cost of the charging pile. In a high humidity environment, the filter cotton is easy to saturate, and the filtering efficiency is greatly reduced, so that the dustproof and waterproof performance of the charging pile is greatly discounted. Therefore, finding a more efficient and easy-to-maintain dustproof and waterproof solution has become a problem to be solved in the field of charging pile design. SUMMARY

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0032] As shown in Figure 1 and 2 The dust and mist removal module of the embodiment of the utility model comprises a shutter rainproof assembly 1, a scroll tube dust removal assembly 2 and a demisting assembly 3. The shutter rainproof assembly 1 comprises a plurality of louvered fan leaves 11 arranged obliquely, and air ducts are formed between the louvered fan leaves 11. The scroll tube dust removal assembly 2 is located on one side of the air duct, and is used for removing dust from mist-containing air passing through the air duct. The demisting assembly 3 is located on one side of the scroll tube dust removal assembly 2, and is used for removing mist from the dust-removed mist-containing air.

[0033] The dust and mist removal module of the utility model can efficiently remove rainwater, dust particles and mist droplets in air, filter different sizes of foreign matters in air from high to low, and improve the water and dust removal efficiency. The modular design makes each component easy to disassemble and replace, and improves the maintenance efficiency. Compared with the filter cotton dust removal mode, the scroll tube dust removal assembly 2 can separate air and dust by centrifugal force, avoids dust accumulation, and reduces the maintenance difficulty and cost. Compared with the several-shaped air duct, air can enter the charging pile through the air duct between the louvered fan leaves, the scroll tube dust removal assembly and the demisting assembly in turn, the air passes through less rigid barriers, ensures the waterproof and dustproof, ensures the air inlet area, the air duct has small resistance, and this is beneficial to reducing the rotation speed of the charging pile fan, thereby reducing the heat dissipation noise.

[0034] As shown in Figure 1 In one embodiment of the utility model, the shutter rainproof assembly 1, the scroll tube dust removal assembly 2 and the demisting assembly 3 can be arranged axially along the air inlet direction in turn, so that the whole module has small volume and compact structure, is convenient to install on the charging pile, and does not occupy too much space.

[0035] As shown in Figure 3 andFigure 4 As shown, in one embodiment of this utility model, the vortex tube dust removal assembly 2 includes: a vortex tube 21 and a cyclone separator 22. The vortex tube 21 has a cavity formed inside for rotating mist-laden air, and the outlet 21a of the vortex tube 21 faces the demisting assembly 3. The cyclone separator 22 is located at the inlet 21b of the vortex tube 21 and is used to guide the mist-laden air to rotate. The cyclone separator 22 has the characteristics of a large aspect ratio, high drag coefficient, and high separation efficiency. Based on the principle of rotational flow in fluid mechanics, when the guide vanes of the cyclone separator 22 rotate, the dust particles in the mist-laden air are subjected to centrifugal force, resulting in different trajectories depending on their mass and density. Heavier dust particles are pushed towards the inner wall of the vortex tube 21 due to the greater centrifugal force and move towards the bottom of the tube under gravity, eventually being collected. Clean air is maintained in the central region of the airflow and discharged through the outlet 21a, thus achieving gas-solid separation.

[0036] In one specific embodiment of this utility model, the cyclone separator 22 can be an axial flow guide vane type cyclone separator, which has the characteristics of large length-to-diameter ratio, high drag coefficient, and high separation efficiency, thus achieving good dust removal effect. Its efficient particle capture capability can greatly reduce the concentration of particulate matter in foggy air.

[0037] In some other embodiments of this utility model, the air inlet 21b of the vortex tube 21 can be guided by other devices such as a guide tube to rotate the misty air, and this embodiment does not limit this.

[0038] In one embodiment of this utility model, the air outlet 21a is provided on the air outlet channel extending outward from the bottom of the vortex tube. The bottom of the vortex tube 21 may also be provided with a dust discharge port 21c for discharging heavier dust particles collected by the vortex tube. The opening direction of the dust discharge port 21c is perpendicular to the air outlet direction of the misty air output from the air outlet channel, so that the dust can be discharged in advance before reaching the air outlet 21a, avoiding re-mixing with the air and entering the demisting component 3.

[0039] like Figure 5 As shown, in one specific embodiment of this utility model, the vortex tube dust removal assembly 2 may include multiple vortex tubes 21, and each vortex tube 21 has a corresponding cyclone separator 22 at its air inlet 21b. The multiple vortex tubes 21 can be arranged in an array and fixed by a bracket 23. In some other embodiments of this utility model, the size and arrangement of the vortex tubes 21 and the cyclone separator 22 can be adjusted according to actual needs, and this embodiment does not impose any limitations.

[0040] like Figure 6As shown, in one embodiment of this utility model, the defogging component 3 is a baffle blade defogging component 3, which includes multiple parallel and spaced baffle blades 31. A series of tortuous flow channels can be formed between the multiple baffle blades 31, increasing the opportunity for mist droplets in the airflow to contact the blades. When the airflow containing mist droplets passes through these blades, due to the change and acceleration of the airflow, the mist droplets are subjected to inertial force, causing their trajectory to change, thereby colliding with the blade surface and achieving effective defogging.

[0041] like Figure 7 and Figure 8 As shown, in one embodiment of the present invention, the deflector blade 31 has a plurality of deflector teeth 31b on its deflector blade body 31a, and a hydrophobic groove 31c is formed between the deflector teeth 31b and the deflector blade body 31a. The design of the hydrophobic groove 31c allows the captured droplets to be quickly concentrated and discharged, reducing the residence time of the droplets on the blade surface and avoiding the re-entrainment of droplets and the pollution of the airflow.

[0042] In some other embodiments of this utility model, the defogging component 3 may be a component with defogging function, including but not limited to a corrugated blade defogging component or an electrostatic demister, in addition to using baffle blades. This embodiment does not limit it.

[0043] like Figure 1 , Figure 9 and Figure 10 As shown, in one embodiment of this utility model, the dust removal and defogging module may further include: a wire mesh filter assembly 4, which includes multiple layers of woven wire mesh 41. The woven wire mesh 41 is used to filter the fog-containing air after defogging. Each layer of woven wire mesh 41 can intercept fog droplets in the airflow, thereby improving the overall filtration efficiency.

[0044] Preferably, the mesh size of the woven wire mesh 41 can be designed to be 10 to 50 micrometers to ensure that airflow is maintained while effectively capturing droplets of the target particle size; through the continuous filtration effect of multiple layers of high-density woven wire mesh 41, it can be ensured that the airflow reaches a high degree of cleanliness after passing through the wire mesh filter assembly 4, meeting the air quality requirements of the charging pile.

[0045] In one embodiment of this utility model, the dust removal and defogging module may further include: a monitoring unit for monitoring the filtration efficiency of the dust removal and defogging module and the air quality of the air passing through the dust removal and defogging module, so that the dust removal and defogging module can automatically adjust the operating parameters such as the fan speed inside the charging pile according to the filtration efficiency and air quality to adapt to different environmental conditions and ensure continuous and efficient filtration performance.

[0046] Specifically, the monitoring unit can employ a particulate matter sensor, such as a lidar, to detect the dust and mist content of the filtered air, and further monitor the filtering efficiency of the dust and mist removal module and the air quality of the air passing through the dust and mist removal module.

[0047] In addition, the utility model provides a charging pile to realize the above-mentioned purpose.

[0048] The charging pile of the embodiment of the utility model comprises the dust and mist removal module as described above. Specifically, the dust and mist removal module can be arranged on the cabinet on one side of the fan in the charging pile, or arranged at other positions on the cabinet of the charging pile according to actual requirements, and the embodiment is not limited,

[0049] The charging pile according to the embodiment of the utility model has the beneficial effects of the dust and mist removal module.
