Description

Technical Field

[0001] This utility model relates to the field of electrostatic dust removal technology, specifically to an electrostatic dust removal device. Background Technology

[0002] In critical sectors such as power systems and motor manufacturing, insulating bushings are core components ensuring the safe operation of electrical equipment, and their performance stability is paramount. Once dust and other contaminants adhere to the surface of the insulating bushing, they can easily cause serious problems such as decreased insulation performance and flashover, thereby threatening the reliable operation of the entire power system. Therefore, effective dust prevention during the adhesive application process has become a key technical bottleneck in improving the reliability of insulating bushings.

[0003] However, traditional silicone sleeve coating processes generally employ an open operation mode. The shaped preform must pass through a fixed mold and into an open container holding silicone rubber to complete the coating, before being pulled to a fixed oven for drying and rewinding. This process exposes the entire process to an open environment, making it impossible to effectively control airborne dust. During coating, dust inevitably mixes with the adhesive or adheres directly to the sleeve surface, contaminating the adhesive, reducing coating quality, and affecting subsequent drying and shaping, ultimately significantly reducing the insulation performance of the sleeve. While some existing dust removal technologies can purify the air to some extent, such as electrostatic precipitators, when used for silicone sleeve coating, dust adsorbed on the collecting electrode is easily dislodged by equipment vibration, re-contaminating the working environment or falling into the adhesive container, reducing the dust removal effect and making dust difficult to clean.

[0004] To address the aforementioned problems, this application proposes an electrostatic dust removal device. Utility Model Content

[0005] The purpose of this utility model is to provide an electrostatic dust removal device to solve the problems mentioned in the background art, such as the easy adhesion of dust to the insulating sleeve, the easy falling of dust during dust removal by traditional electrostatic dust removal technology, and the inconvenience of dust cleaning.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electrostatic dust removal device, comprising a housing, baffles fixedly installed on both sides of the housing, and notches opened on the sides of the baffles; a discharge electrode, a dust collection electrode, and a U-shaped support plate are installed on the inner side of the housing, the U-shaped support plate is located at the lower end of the discharge electrode and the dust collection electrode, and a glue groove is placed on its inner side; an air outlet pipe and a fan are installed at the upper end of the housing, and the air outlet pipe is connected to the fan.

[0007] Preferably, the dust collection electrodes are in multiple groups, vertically distributed inside the outer shell. Each group of dust collection electrodes consists of two opposing right-angled triangular structural units. The right-angled sides of each unit are fixedly connected to the inner surfaces of the front and rear ends of the outer shell, with the hypotenuses facing downwards and extending into the cavity formed by the outer shell and the two end faces of the U-shaped support plate.

[0008] Preferably, the discharge electrode consists of multiple sets of high-frequency pulse electrostatic generators, which are horizontally installed inside the housing and uniformly distributed in an array on one side of multiple adjacent dust baffles.

[0009] Preferably, the upper end of the gap between two adjacent sets of dust collecting electrodes is connected to the air outlet pipe through a corresponding pipe.

[0010] Preferably, dust baffles are provided on both sides of the dust collecting electrode. The dust baffles are positioned at the inclined side of the dust collecting electrode and kept parallel, and adopt an arc-shaped structure with the outer curved surface facing down and the inner curved surface facing up.

[0011] Preferably, a vibration motor is fixedly installed on both the front and rear outer surfaces of the housing.

[0012] Preferably, a dust collection chamber is provided at the bottom of the outer shell, which is connected to the cavity formed between the U-shaped support plate and the outer shell, and a collection box can be detachably installed at its bottom.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention generates a high-voltage electrostatic field through a discharge electrode, charging the dust particles. This charge forms an electric field region with the dust collection electrode. A fan generates suction through the air outlet pipe, causing directional airflow. The charged dust particles are adsorbed onto the dust collection electrode under the action of the electric field, thus purifying the air and preventing dust from sticking to the insulating sleeve when applying adhesive. At the same time, the arc-shaped dust baffles on both sides of the dust collection electrode have their outer curved surface facing down and their inner curved surface facing up, catching the dust that falls off after vibration and preventing it from falling into the adhesive tank and contaminating the adhesive, thus ensuring a clean environment for applying adhesive to the insulating sleeve.

[0015] This invention provides a dust collection channel by connecting the dust collection chamber at the bottom of the outer shell with the cavity between the U-shaped support plate and the outer shell. Under the action of the vibrating motor, the dust on the dust collection electrode falls off and falls into the dust collection chamber through the cavity for temporary storage. The bottom of the dust collection chamber adopts a detachable collection box. When the dust is full, it can be quickly disassembled, cleaned and reinstalled, simplifying the maintenance process, reducing the difficulty of manual cleaning and ensuring the long-term stable operation of the electrostatic dust removal device.

[0024] 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.

[0025] Please see Figures 1-7This utility model provides a technical solution: an electrostatic dust removal device, including a shell 1, with baffles 2 fixedly installed on both sides of the shell 1. Each baffle 2 has a notch on its side. A discharge electrode 3, a dust collecting electrode 4, and a U-shaped support plate 5 are installed inside the shell 1. The U-shaped support plate 5 is located at the lower end of the discharge electrode 3 and the dust collecting electrode 4, and a glue tank 6 is placed inside it. An air outlet pipe 7 and a fan 8 are installed at the upper end of the shell 1, and the air outlet pipe 7 is connected to the fan 8. The baffles 2 on both sides of the shell 1 serve to define boundaries and initially block dust diffusion, reducing the direct intrusion of external dust. The discharge electrode 3 generates a high-voltage electrostatic field after being energized, causing dust particles in the air entering the shell 1 to become charged. The dust collecting electrode 4 cooperates with the discharge electrode 3 to form an area of ​​electric field force. The U-shaped support plate 5 supports the glue tank 6, providing a stable platform for the gluing operation of the insulating sleeve. When the insulating sleeve enters or exits from the inlet and outlet of the baffles 2 on both sides of the shell 1, the gluing process is completed within the glue tank 6. During this period, the fan 8 starts and generates suction, which draws the dust-laden air inside the outer casing 1 upward through the air outlet pipe 7, causing the air to flow in a directional manner within the device. Under the action of the electric field force, the charged dust particles move towards the dust collecting electrode 4, thereby achieving the separation of dust from air and preventing dust from contaminating the insulating sleeve that is being glued.

[0026] Multiple sets of dust collecting electrodes 4 are vertically distributed inside the outer casing 1. Each set of dust collecting electrodes 4 consists of two opposing right-angled triangular structural units. The right-angled sides of each unit are fixedly connected to the inner surfaces of the front and rear ends of the outer casing 1, with the hypotenuses facing downwards and extending into the cavity formed by the outer casing 1 and the two end faces of the U-shaped support plate 5. The multiple sets of dust collecting electrodes 4 vertically distributed inside the outer casing 1 increase the contact area with charged dust particles and improve dust removal efficiency. Each set of dust collecting electrodes 4 consists of two opposing right-angled triangular structural units. Its unique design, with the right-angled sides fixedly connected to the inner surfaces of the front and rear ends of the outer casing 1 and the hypotenuses extending downwards into a specific cavity, allows dust to slide down along the hypotenuses into the cavity formed by the outer casing 1 and the two end faces of the U-shaped support plate 5 under the combined action of its own gravity and electric field, facilitating subsequent collection and processing and ensuring that dust does not re-enter the adhesive area of ​​the insulating sleeve.

[0027] The discharge electrode 3 consists of multiple sets of high-frequency pulse electrostatic generators, horizontally mounted inside the housing 1, and uniformly distributed in an array on one side of adjacent dust baffles 12. The discharge electrodes 3, horizontally mounted and uniformly distributed on one side of adjacent dust baffles 12, form a stable and widely distributed electrostatic field within the housing 1. When dust-laden air passes through this area, the dust particles quickly become charged and move towards the dust collecting electrode 4 under the drive of the electric field, laying the foundation for efficient dust removal. The dust baffles 12 can, to a certain extent, prevent dust diffusion, causing the charged dust particles to move more concentratedly towards the dust collecting electrode 4.

[0028] The upper ends of the gaps between two adjacent sets of dust collecting electrodes 4 are connected to the air outlet pipe 7 via corresponding pipes; this design forms a channel for airflow. Under the suction of the fan 8, air carrying charged dust particles passes through the gaps between adjacent dust collecting electrodes 4. Since the surface of the dust collecting electrode 4 carries an opposite charge to the dust particles, the charged dust particles are adsorbed onto the surface of the dust collecting electrode 4 under the action of the electric field. The purified air is then discharged from the device through the connecting pipe and the air outlet pipe 7, achieving orderly airflow and efficient purification within the device, ensuring a clean environment for the adhesive application of the insulating sleeve.

[0029] Dust baffles 12 are arranged on both sides of the dust collecting electrode 4. The dust baffles 12 are positioned at the inclined side of the dust collecting electrode 4 and kept parallel, and adopt an arc-shaped plate structure with the outer curved surface facing down and the inner curved surface facing up. The dust baffles 12 arranged on both sides of the dust collecting electrode 4 adopt an arc-shaped plate structure with the outer curved surface facing down and the inner curved surface facing up, and are installed at the inclined side of the dust collecting electrode 4 and kept parallel. When the vibration motor 9 is started to drive the outer casing 1 and the dust collecting electrode 4 to vibrate, the dust adsorbed on the dust collecting electrode 4 will fall off due to the vibration. Since the inner curved surface of the dust baffle 12 faces up, it can catch the falling dust and prevent the dust from falling directly into the glue tank 6 below, avoiding contamination of the glue. At the same time, the dust baffle 12 is inclined downward. Under the action of the vibration of the outer casing 1, the dust can slide down the inclined surface of the dust baffle 12 into the dust collection chamber 10, realizing effective collection and isolation of dust, and ensuring that the glue application process of the insulating sleeve is not affected by dust.

[0030] In this embodiment, as Figure 2 and Figure 3 As shown, vibration motors 9 are fixedly installed on the front and rear outer surfaces of the outer casing 1. These motors generate mechanical vibration upon startup and transmit the vibration to the outer casing 1 and the dust collecting electrode 4 inside. Under the vibration, the dust adsorbed on the surface of the dust collecting electrode 4 is broken down and detached. This vibration method effectively cleans the dust on the surface of the dust collecting electrode 4, preventing excessive dust accumulation that could affect the dust removal effect, ensuring the dust collecting electrode 4 maintains good adsorption performance, and guaranteeing the long-term stable operation of the electrostatic precipitator.

[0031] A dust collection chamber 10 is located at the bottom of the outer casing 1. The dust collection chamber 10 is connected to the cavity formed between the U-shaped support plate 5 and the outer casing 1, and a collection box 11 is detachably installed at its bottom. The dust collection chamber 10 at the bottom of the outer casing 1, connected to the cavity formed between the U-shaped support plate 5 and the outer casing 1, creates a dedicated dust collection channel. During the operation of the electrostatic precipitator, the dust adsorbed by the dust collecting electrode 4 is detached under the drive of the vibration motor 9, and then, under the combined action of its own gravity and the vibration of the outer casing 1, falls smoothly into the dust collection chamber 10 along the specific cavity for temporary storage, effectively preventing dust from spreading inside the device. The detachable collection box 11 at the bottom of the dust collection chamber 10 greatly improves the convenience of dust cleaning. When the dust in the collection box 11 accumulates to a certain amount, it can be quickly removed from the bottom of the dust collection chamber 10, emptied, cleaned, and reinstalled. This design optimizes the maintenance process, reduces the difficulty of manual cleaning, ensures the continuous and efficient operation of the electrostatic precipitator, and maintains a good dust removal effect.

[0032] Working principle:

[0033] First, place the electrostatic dust removal device between the conveying path of the insulating sleeve blank and the oven, ensuring that the inlet and outlet of the baffles 2 on both sides of the outer shell 1 are aligned with the conveying direction of the blank. The glue tank 6 on the U-shaped support plate 5 has been filled with an appropriate amount of adhesive, and the collection box 11 at the bottom of the dust collection chamber 10 is installed in place. Then, turn on the device. The discharge electrode 3 is energized to generate a high-voltage electrostatic field, and the fan 8 starts, generating suction through the exhaust pipe 7. The insulating sleeve blank enters from the inlet and outlet of the baffle 2 on one side of the outer shell 1, and is coated with adhesive in the glue tank 6. The traction rollers at both ends and in the middle of the glue tank 6 limit its movement. At this time, air containing dust enters from the openings on both sides of the outer shell 1. The air flows upward under the suction of the fan 8. When passing through the area of ​​the discharge electrode 3, the dust particles are ionized by the electrostatic field and become charged. The charged dust particles enter the gap between two adjacent sets of dust collection electrodes 4 with the air. Because the surface of the dust collection electrodes 4 carries opposite charges, the dust particles are adsorbed onto the surface of the dust collection electrodes 4 under the action of the electric field. The purified air is discharged from the exhaust pipe 7 through the connecting pipe. After the work is completed, the vibration motor 9 is started to drive the outer casing 1 and the dust collecting electrode 4 to vibrate, causing the dust adsorbed on the dust collecting electrode 4 to fall off. The dust baffles 12 on both sides of the dust collecting electrode 4 collect the dust, and their downward-sloping arc structure allows the dust to slide down into the dust collection chamber 10 under the action of vibration, and finally enter the collection box 11 to complete the dust collection. When the dust in the collection box 11 accumulates to a certain amount, it is removed from the bottom of the dust collection chamber 10 for cleaning. After reinstallation, the device can continue to operate stably.
