Description

Technical Field

[0001] This utility model relates to the field of capacitor processing equipment technology, and in particular to a dust reduction device for a powder packaging machine. Background Technology

[0002] Electronic components mainly include ceramic capacitors, film capacitors, mica capacitors, monolithic capacitors, tantalum capacitors, varistors, network resistors, PTCs, NTCs, inductors, etc. They must be insulated and encapsulated. Powder encapsulation technology for electronic components has replaced traditional liquid encapsulation technology in various electronic component production fields due to its characteristics such as solvent-free, pollution-free, excellent electrical performance, high encapsulation efficiency, and ease of large-scale production. Powder encapsulation machines are the key equipment for this process.

[0003] Powder coating technology is a thermal coating technology that uses a fluidized bed coating method to apply insulating powder to preheated electronic components. Then, by heating the components, the insulating powder is melted onto the outer surface of the components, forming a uniform insulating film. At this point, the insulating coating does not yet have the required insulation and mechanical strength. The coated components are then further heated and cured for 1 to 2 hours, forming a strong insulating layer on the surface of the electronic components.

[0004] Currently, in the film capacitor industry, a large amount of powder leaks out during the powder packaging process. Existing technology only prevents powder leakage by opening and closing shielding doors and using high-power exhaust fans to isolate the powder workshop and powder packaging machines for dust extraction. The extracted dust is then directly discharged. However, because the workshop space is large, the powder cannot be completely removed; at the same time, the extracted powder is directly discharged, polluting the environment. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a dust suppression device for powder packaging machines, which solves the problem of direct powder emission and environmental pollution during the processing of powder packaging machines in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides a dust suppression device for a powder packaging machine, comprising a powder packaging machine body, a dust discharge pipe disposed in the powder packaging machine body, and a fan disposed in the powder packaging machine body for conveying dust to the dust discharge pipe. The dust discharge pipe has a dust suppression box connected to it at its end, an air inlet connected to the dust discharge pipe, and an air outlet for exhausting air. The bottom of the dust suppression box has a dust collection basin for holding liquid to absorb dust, and a guide plate assembly disposed above the dust collection basin to guide the airflow direction and increase the gas flow path.

[0007] By adopting the above technical solution, the dust generated during the operation of the powder packaging machine can be transported to the dust settling box by a fan and dust exhaust pipe before being discharged. The air containing dust is guided to the dust settling pool by the air guide plate assembly in the dust settling box. The dust is adsorbed by the liquid in the dust settling pool, thus achieving dust filtration of the air. The air guide plate assembly increases the airflow distance in the dust settling box, making the dust settling effect better. Furthermore, the use of wet dust settling can quickly adsorb the fine particles in the capacitor dust and allow the gas after dust settling to be discharged from the air outlet, achieving green emissions and reducing environmental pollution.

[0008] In one embodiment of the present invention, the air guide plate assembly includes a first air guide plate disposed on the lower side of the air outlet and inclined in the direction of the air outlet axis, a second air guide plate disposed on the lower side of the air outlet, and a third air guide plate disposed between the first air guide plate and the second air guide plate. The upper ends of the first air guide plate and the second air guide plate are both closedly connected to the upper end of the dust settling box, and the lower ends of the first air guide plate, the second air guide plate, and the third air guide plate are all gap-fitted with the dust settling pool.

[0009] By adopting the above technical solution, the inclined first air guide plate can cause the gas to be gathered towards the bottom of the dust settling box after entering the dust settling box, so that the air containing dust enters the dust settling pool for dust settling treatment. Then, the second air guide plate and the third air guide plate increase the contact time between the air and the liquid in the dust settling pool, thereby improving the dust settling effect.

[0010] In one embodiment of the present invention, the second air guide plate is arranged in a vertical direction, the third air guide plate is inclined in the opposite direction to the second air guide plate, and the upper end of the third air guide plate is fitted with a gap at the upper end of the dust collection box.

[0011] By adopting the above technical solution, it is easier to guide the airflow inside the dust collection box and improve the dust collection effect.

[0012] In one embodiment of the present invention, the air outlet is disposed on the upper surface of the dust collection box and on the other side of the dust collection box opposite to the air inlet. A filter screen is also disposed on the air outlet, and the filter screen is detachably installed on the upper side of the air outlet.

[0013] By adopting the above technical solution, additional filters can be added to further physically reduce dust in the air, ensuring that the emitted gas does not pollute the surrounding environment.

[0014] In one embodiment of this utility model, the air outlet is rectangular in shape, the filter is shaped to correspond to the air outlet shape, and two L-shaped limiting plates are arranged opposite to each other on the air outlet, with the filter being inserted into the two L-shaped limiting plates.

[0015] By adopting the above technical solution, the filter screen can be quickly disassembled and replaced, which facilitates later maintenance.

[0016] In one embodiment of the present invention, a dust settling pool is disposed on the bottom plate of a dust settling box, the dust settling pool is slidably connected to the dust settling box in a horizontal direction, and an end cap is provided at the end of the dust settling pool, the end cap being sealed to the outer wall of the dust settling pool.

[0017] By adopting the above technical solution, the dust collection tank can be detachably connected, which facilitates the cleaning and maintenance of the dust collection box.

[0018] In one embodiment of the present invention, the bottom of the dust settling tank is configured as a guide slope inclined to one side, the guide slope being inclined downward from the air outlet side.

[0019] By adopting the above technical solution, dust in the dust settling tank can be concentrated on one side of the dust settling tank, making it easier to clean and maintain later.

[0020] As described above, the dust suppression device for the powder packaging machine of this utility model has the following beneficial effects: the dust generated during the operation of the powder packaging machine can be transported to the dust suppression box by a fan and a dust discharge pipe before being discharged. The air containing dust is guided to the dust suppression pool by the air guide plate assembly in the dust suppression box. The dust is adsorbed by the liquid in the dust suppression pool, thus achieving dust filtration of the air. The air guide plate assembly increases the airflow path in the dust suppression box, making the dust suppression effect better. Furthermore, the use of wet dust suppression can quickly adsorb the tiny particles in the powder and discharge the dust-suppressed gas from the outlet, achieving green emissions and reducing environmental pollution.

[0029] The bottom of the dust settling box 2 is equipped with a dust settling pool 5 that can hold liquid for adsorbing dust and an air guide plate group 6 that is set above the dust settling pool 5 to guide the airflow direction and increase the gas flow path.

[0030] The air guide plate assembly 6 includes a first air guide plate 20 disposed on the lower side of the air outlet 4 and inclined in the direction of the axis of the air outlet 4, a second air guide plate 21 disposed on the lower side of the air outlet 4, and a third air guide plate 22 disposed between the first air guide plate 20 and the second air guide plate 21.

[0032] Gas enters the dust settling box 2 through the air inlet 3 and is guided to the dust settling pool 5 at the bottom of the dust settling box 2 by the first air guide plate 20. There is a gap between the lower end of the first air guide plate 20 and the liquid in the dust settling pool 5.

[0033] The air outlet 4 is located on the upper surface of the dust collection box 2 and is located on the other side of the dust collection box 2 opposite to the air inlet 3. A filter screen 7 is also provided on the air outlet 4. The filter screen 7 is detachably installed on the upper side of the air outlet 4.
