Description

Technical Field

[0001] This utility model relates to the field of high-voltage electrostatic devices, specifically an environmentally friendly high-voltage electrostatic device. Background Technology

[0002] The production process of nonwoven fabrics generates fumes, which contain acidic substances, small particles and other substances harmful to the air. Before the fumes are emitted, they need to be treated to ensure that they meet the standard requirements. High-voltage electrostatic devices can be used to treat the fumes. By modifying the electric field at the emission point, various forces such as Lorentz force are used to treat the fumes in an environmentally friendly way.

[0003] Existing environmentally friendly high-voltage electrostatic devices, such as the electrostatic smoke treatment device and method proposed in patent application number "CN202010415159.5", include a two-stage electrostatic treatment mechanism, which is set above a chimney and connected to a high-voltage power supply. Each stage of the electrostatic treatment mechanism includes multiple linear discharge electrodes and collecting electrodes arranged circumferentially to form inner and outer cylinders, and a baffle is set in each stage. A heat pipe runs through the two baffles, directly opposite the center of the chimney. Smoke and ambient air undergo heat and moisture exchange and chemical reactions within the electrostatic treatment device. Collisions between droplets and particles with the electrodes cause the conductive droplets captured by the electrodes to eject charged particles. The captured droplets and particles migrate to the collection container under the influence of gravity and electrode vibration. This device avoids spark discharge, is lightweight, has low flow resistance, and can synergistically capture various vapors and particles in smoke.

[0004] However, existing technologies have drawbacks. The device is installed above the chimney and exposed to the air. When the device is running, it guides, captures, and collects particulate matter in the smoke. When the device is not running, dust in the air easily falls on the electrode surface of the device. The dust on the electrode surface will affect the electrode performance and lifespan, and will also bring certain safety hazards to the device. Therefore, an environmentally friendly high-voltage electrostatic device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an environmentally friendly high-voltage electrostatic device to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An environmentally friendly high-voltage electrostatic device includes an internal component and an external component. The external component covers the internal component. The internal component includes a mounting frame installed above the smoke outlet of a chimney. Multiple sets of electrodes are snapped onto the mounting frame and arranged in a circular array. The external component includes two sets of supports symmetrically installed on the chimney. Two sets of protective covers are rotatably connected between the two sets of supports. One side of each set of protective covers abuts against the other side, and the lower ends of each set of protective covers abut against the upper ends of the two sets of supports. The internal component is located inside the two sets of protective covers.

[0008] Preferably, each of the multiple sets of electrodes is fitted with a claw at both ends, the claw being "C" shaped and engaging with the mounting bracket.

[0009] Preferably, each of the two sets of brackets has a fixed frame on one side, and each of the two sets of fixed frames has a mounting ring fixed at its end. The mounting ring is semi-circular in shape, and the two sets of mounting rings are bolted to the chimney. Each of the two sets of brackets has a grounding post fixed at its lower end, and the grounding post is supported and cooperates with the chimney mounting surface.

[0010] Preferably, a column is fixedly connected to one side of the lower end of the protective cover, and the two ends of the column are rotatably connected to two sets of brackets respectively. A gear is fixedly connected to both ends of the column, and the two sets of gears are located outside the two sets of brackets.

[0011] Preferably, two sets of ears are fixedly connected to each of the two sets of brackets, and a second gear is rotatably connected to the ear, which meshes with the first gear for transmission.

[0012] Preferably, each of the two sets of protective covers has a support column fixed to the side away from the internal components, the support column being used to support the deployed protective cover.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes a snap-fit ​​installation for the internal electrodes, facilitating the replacement of substandard or damaged electrodes. An external component is installed on the chimney, while the internal component, used to capture and collect vapor and particulate matter in the smoke, is located inside the external component. When the device is running, the two sets of protective covers are rotated and opened, exposing the internal component to the air. When the device is not running, the two sets of protective covers are closed, preventing the internal component from being exposed to the air and preventing dust from falling onto the electrode surface and affecting the electrodes when the device is not running.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] An environmentally friendly high-voltage electrostatic device, such as Figures 1-4 As shown, the device includes internal and external components. The external components cover the internal components. The internal components include a mounting frame 2, which is installed above the smoke outlet of the chimney 1. Multiple sets of electrodes 3 are snapped onto the mounting frame 2 and arranged in a circular array. The external components include two sets of supports 5, which are symmetrically installed on the chimney. Two sets of protective covers 9 are rotatably connected between the two sets of supports 5. The two sets of protective covers 9 abut against each other on one side to cover the internal components. The lower ends of the two sets of protective covers 9 abut against the upper ends of the two sets of supports 5, so that the upper ends of the supports 5 support the lower ends of the protective covers 9. The internal components are located inside the two sets of protective covers 9.

[0024] The function and arrangement of the mounting frame 2 and the multiple sets of electrodes 3 are existing technologies. By changing the electric field around the smoke outlet of the chimney 1, the particles in the smoke are captured and collected. The multiple sets of electrodes 3 are installed with the mounting frame 2 by snap-fit, which makes it easy to disassemble and replace the electrodes 3 independently. It is also easy to replace the electrodes 3 with poor performance or damaged electrodes 3, thereby reducing the maintenance cost of the device.

[0025] By installing an external component on the chimney 1, an internal component for capturing and collecting vapors and particulate matter in the smoke is located inside the external component. When the device is running, the two sets of protective covers 9 are controlled to rotate and open, exposing the internal component to the air. When the device is not running, the two sets of protective covers 9 are controlled to close, so that the internal component is not exposed to the air, preventing dust in the air from falling on the surface of the electrode 3 when the device is not running and affecting the electrode 3.

[0026] like Figure 3 As shown, each of the multiple sets of electrodes 3 has a claw 4 inserted and installed at both ends. The claw 4 is shaped like a "C" and is engaged with the mounting bracket 2.

[0027] First, insert and install the claws 4 at both ends of the electrode 3, and then snap the claws 4 onto the mounting bracket 2, thereby installing the electrode 3 on the mounting bracket 2. The number and spacing of the electrodes 3 can be adjusted according to the requirements, which effectively facilitates the disassembly and installation of the electrodes 3.

[0028] like Figure 2 As shown, each of the two sets of brackets 5 has a fixed frame 7 fixedly connected to one side, and each of the two sets of fixed frames 7 has a mounting ring 8 fixedly connected to its end. The mounting ring 8 is semi-circular in shape. The two sets of mounting rings 8 are bolted to the chimney 1. Each of the two sets of brackets 5 has a grounding post 6 fixedly connected to its lower end. The grounding post 6 is supported and cooperates with the mounting surface of the chimney 1.

[0029] The mounting brackets 7 are symmetrically located on both sides of the chimney 1 and installed on the side wall of the chimney 1, making it easy to remove from the chimney 1. The external components can be made of insulating materials or non-insulating materials. When non-insulating materials are used, grounding posts 6 are required to ground the external components to prevent them from becoming energized.

[0030] like Figures 1-4 As shown, a column 10 is fixedly connected to one side of the lower end of the protective cover 9. The two ends of the column 10 are rotatably connected to two sets of brackets 5 respectively. Gears 11 are fixedly connected to both ends of the column 10. Both sets of gears 11 are located outside the two sets of brackets 5.

[0031] The column 10 protrudes from the bottom of the protective cover 9 and is rotatably connected to the two sets of brackets 5. When the gear 11 is driven to rotate by the external drive component, the column 10 rotates, thereby driving the protective cover 9 to rotate and controlling the protective cover 9 to close or open.

[0032] like Figure 3 As shown, two sets of ears 12 are fixedly connected to each of the two sets of brackets 5. A second gear 13 is rotatably connected to the ear 12, and the second gear 13 meshes with the first gear 11 for transmission.

[0033] Gear 11 is driven to rotate by gear 2 13, which indirectly drives the rotation, reducing the reverse force on the external driving component and making it easier to drive the protective cover 9 to rotate.

[0034] like Figures 1-2 As shown, each of the two sets of protective covers 9 has a support column 14 fixed to the side away from the internal components. The support column 14 is used to support the unfolded protective cover 9.

[0035] The support column 14 is made of elastic insulating material to prevent the protective cover 9 from contacting the mounting surface of the chimney 1 after it is opened, thereby reducing the rotation range of the protective cover 9 and reducing the difficulty of driving the protective cover 9 to rotate.

[0036] The working principle of the environmentally friendly high-voltage electrostatic device provided by this utility model is as follows:

[0037] By installing an external component on the chimney 1, the internal component for capturing and collecting vapor and particulate matter in the smoke is located inside the external component. When the device is running, the two sets of protective covers 9 are rotated and opened by the control of gear 2 13, gear 1 11 and column 10, so that the internal component is exposed to the air and will not affect the operation of the internal component. When the device is not running, the two sets of protective covers 9 are controlled to close, so that the internal component is not exposed to the air, and prevents dust in the air from falling on the surface of electrode 3 when the device is not running, thus affecting electrode 3.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
