Description

A kind of dust collect plant produced for printed circuit board (PCB)

Technical field

This utility model relates to the tool of production of a kind of printed circuit board (PCB), particularly relates to a kind of printed circuit board (PCB) raw The dust collect plant produced.

Background technology

During producing printed circuit board (PCB), needing circuit board is polished polishing, this will produce a lot Dust.In traditional mode of production mode, these dust directly get rid of outdoor, to air and environment by exhaust blower Impact is very big, can cause environmental pollution.

Utility model content

In order to solve problem present in background technology, this utility model provides a kind of dust collect plant, this dress Put the dust that can produce during collecting circuit plate polishing grinding, it is to avoid environmental pollution.

For reaching above-mentioned purpose, this utility model adopts the following technical scheme that

A kind of dust collect plant produced for printed circuit board (PCB), including dust bucket, it is characterised in that described collection The open upper end of dust barrel, lower end closed, the upper surface diameter of dust bucket is more than bottom end face diameter；Dust bucket Sidewall on be provided with into dirt hole, enter and be fixed with sweep-up pipe by retaining collar on dirt hole, arrange in sweep-up pipe Having air inlet fan, the free end of sweep-up pipe is suction port, and the suction port of sweep-up pipe is arranged on printed circuit board (PCB) Workshop；

The bottom of dust bucket is provided with water, and the top of dust bucket is provided with twice drainage screen, the respectively first mistake Filter screen and the second drainage screen, the first drainage screen is arranged on the top end face of dust sucking drum, and the second drainage screen is arranged on The bottom of the first drainage screen and be positioned at the top into dirt hole, the mesh diameter of the second drainage screen is greater than first The mesh diameter of drainage screen.

Being provided with filter screen deck on the inwall of described dust bucket, the second drainage screen is fixed on collection by filter screen deck Dust barrel inwall.

The beneficial effects of the utility model are: collect the dust that polishing circuit board produces, it is to avoid to environment Pollute；Use the drainage screen of two road difference meshes, there is more preferable dust removing effects；Dust is all collected into water In, it is simple to process.

Accompanying drawing explanation

Below in conjunction with the accompanying drawings this utility model is further illustrated

Fig. 1 is the structural representation of dust collect plant described in the utility model；

Detailed description of the invention

This utility model is further described by explanation and detailed description of the invention below in conjunction with the accompanying drawings:

Embodiment 1

As it is shown in figure 1, a kind of dust collect plant produced for printed circuit board (PCB), including dust bucket 1, dust The open upper end of bucket 1, lower end closed, the upper surface diameter of dust bucket 1 is more than bottom end face diameter.Dust It is provided with into dirt hole 4 on the sidewall of bucket 1, enters and be fixed with sweep-up pipe 2 by retaining collar 3 on dirt hole 4, inhale Being provided with air inlet fan 8 in dirt pipe 2, the free end of sweep-up pipe 2 is suction port, the suction port of sweep-up pipe 2 It is arranged on the workshop of printed circuit board (PCB).

The bottom of dust bucket 1 is provided with water, and the top of dust bucket 1 is provided with twice drainage screen, and respectively One drainage screen 8 and the second drainage screen 7, the first drainage screen 8 is arranged on the top end face of dust sucking drum 1, and second Drainage screen 7 is arranged on the bottom of the first drainage screen 8 and is positioned at the top into dirt hole 4.Second drainage screen 7 Mesh diameter be greater than the mesh diameter of the first drainage screen 8.

Being provided with filter screen deck 6 on the inwall of dust bucket 1, the second drainage screen 7 is fixed by filter screen deck 6 At dust bucket inwall.

The work process of this dust collect plant is: after polishing work starts, start air inlet fan 8, air inlet fan 8 Being drawn in the lump in dust sucking drum by the gas of band dust in workshop, the heavy granule automatic sedimentation in dust is to dust In the water of the lower end of device, it is simple to collect.Lighter dusty gas, by two metafiltration net mistakes of dust arrester upper end After filter, in the adsorbing powder dust that some are less, lighter to filter screen, clean gas is discharged.

It will be recognized by those skilled in the art, on the premise of without departing from protection scope of the present invention, permissible Above-mentioned embodiment is carried out various amendment, changes and combine, and think this amendment, change and combine Within the scope of originality thought.
