An environmental control device and a particulate filter structure

Abstract

This utility model provides an environmental control device and a particulate filter structure, including: an environmental dust collection component, which includes a dust collection hood, a main dust collection pipe, and a distribution pipe. Compared with the prior art, this utility model has the following beneficial effects: by adding an environmental dust collection component, a cyclone separator, and a post-filter component, two sets of cyclone separators are respectively connected to two distribution pipes of the environmental dust collection component. The two sets of cyclone separators are used to complete the primary particulate filtration. The cyclone separators introduce the filtered air into the post-filter component through the air outlet duct. The particulates are first further captured by the electrostatic dust removal box, and finally the final particulate filtration is achieved by the end filter box, which can improve the environmental control effect. By adding the post-filter component, after the dust collection electrode captures and adsorbs the particulates, the dust collection shaft is rotated by the motor at intervals, which then drives the knocking seat to shake off the dust adsorbed by the dust collection electrode, which can assist in the use of environmental control.

Description

Technical Field

[0001] This utility model belongs to the field of bonding wire production technology, and specifically relates to an environmental control device and a particulate filter structure. Background Technology

[0002] Bonding wires are fine metal wires (usually gold, silver, copper, or alloys) that connect chip pads to lead frames. Their diameter is typically between 15μm and 50μm, and they are the "lifeline" of the chip. Bonding wire production lines usually include processes such as melting, continuous casting, rough drawing, intermediate annealing, fine drawing, final annealing, and winding. In the fine drawing and subsequent production processes, the environmental requirements are particularly high. Dust, particles, and fibers in the production environment are the number one enemies of bonding wire production. The suspension and adhesion of particles can lead to problems such as wire breakage during drawing, bonding failure, and surface defects in bonding wire production. Therefore, the environmental quality requirements in bonding wire production are very high. In existing technologies, in order to quickly adsorb, collect and filter airborne particles, external dust collection equipment and HEPA / ULPA filters are used. Although HEPA / ULPA filters have high filtration efficiency, their dust holding capacity is limited. During the production process, the filters will gradually become clogged, leading to increased wind resistance, decreased wind speed and air volume, and the inability to maintain cleanliness. Therefore, it is necessary to stop the machine to replace the filters, and the replacement frequency is relatively high, which will affect continuous production.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

[0005] This utility model is achieved through the following technical solution: an environmental control device and a particulate filter structure, comprising: an environmental dust collection component, which includes a dust collection hood, a main dust collection pipe and a distribution pipe. The main dust collection pipe is fixedly connected to the top of the dust collection hood, and two distribution pipes are fixedly connected to the top of the main dust collection pipe. A cyclone separator for primary dust filtration is fixedly connected to the other end of each of the two distribution pipes.

Several sets of corona electrodes are fixedly installed in the middle of the inner side of the electrostatic dust collector, and a set of dust collection electrodes is fixedly connected to both the front and rear sides of the corona electrode.

[0006] In a preferred embodiment, a three-way valve is fixedly installed between the main suction pipe and the two distribution pipes, and a set of mounting seats is fixedly connected to the outer side of the other end of each of the two distribution pipes.

[0007] In a preferred embodiment, a set of mounting seats is also fixedly connected to the end of the dust-laden air inlet pipe away from the center of the cyclone separator.

During use, the primary dust removal of the two sets of cyclone separators is switched at intervals, and the passage is switched through a three-way valve.

[0008] In a preferred embodiment, an air outlet duct for discharging dust-removed air is fixedly connected to the top of the main housing, and a connecting flange is fixedly connected to the other end of the air outlet duct.

A set of branch collection pipes are fixedly connected to both the front and rear ends of the left side of the main collection pipe. The corona electrode causes the particles to be carried and attached, and then adsorbed and collected by the dust collection electrode, thereby achieving a further particle filtration effect.

[0010] In a preferred embodiment, a set of connecting flanges is also fixedly connected to the outer side of the end of the collecting branch pipe away from the center of the collecting main pipe, and the two sets of connecting flanges are attached to each other and fixedly connected by bolts.

[0012] In a preferred embodiment, a set of dust removal shafts are rotatably connected to both the front and rear ends of the inner side of the electrostatic dust removal box. Several sets of linearly and equally distributed connecting seats are fixedly connected to the outer side of the dust removal shafts. A knocking seat is rotatably connected below the connecting seats. After the dust collection electrode captures and adsorbs the particles, the dust removal shafts are rotated by the motor at intervals, which in turn causes the knocking seats to shake off the dust adsorbed by the dust collection electrode, which can assist in environmental control.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are: 1. By adding an environmental dust collection component, a cyclone separator, and a post-filter component, two sets of cyclone separators are connected to two delivery pipes of the environmental dust collection component.

The two sets of mounting bases 105 are attached to each other and fixedly connected with bolts. The main housing 201 is fixedly connected to the end of the dust-laden air inlet pipe 202 near the center of the cyclone separator 200. The two sets of cyclone separators 200 are respectively connected to two sets of delivery pipes 104. During use, the primary dust removal of the two sets of cyclone separators 200 is switched at intervals, and the passage is switched through the three-way valve 103.

Both ends of the main collection pipe 301 are fixedly connected to a set of collection branch pipes 302.

The dust removal shaft 307 is rotated intermittently by the motor, and then the tapping seat 309 is rotated by the connecting seat 308, so that the tapping seat 309 taps and shakes off the dust adsorbed by the dust collection electrode 306, thereby assisting in environmental control.
