[0043] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0044] Embodiment 1

[0045] Please refer to Figures 1-6 The present application provides a technical scheme: a smoke dust filtering device for a sensor production line for automobiles, comprising:

[0046] The filter main body 1 comprises a bottom plate 11, an upper mounting plate 12, an upper closing plate 13 and a first filter unit 14, and a plurality of first filter units 14 are arranged between the bottom plate 11 and the upper mounting plate 12;

[0047] The precision filter 2 is connected to the exhaust main pipe 19 of the filter main body 1 at the input end;

[0048] The vacuum generator 5 is connected to the first exhaust branch pipe of the precision filter 2 at the input end;

[0049] The exhaust barrel 3 is connected to the second exhaust branch pipe of the vacuum generator 5 at the input end;

[0050] The gas collecting box 4 is connected to the filter main body 1 through the air inlet main pipe 18;

[0051] Among them, the gas collecting box 4 is provided with a plurality of air suction branch pipes 41, and the air suction branch pipes 41 are provided with air suction ports at the end portions;

[0052] The first filtering unit 14 comprises a first filtering cylinder 141 and a first air pipe 142. The first filtering cylinder 141 is arranged between the bottom plate 11 and the upper mounting plate 12. The upper mounting plate 12 is provided with a first gas discharge hole corresponding to the first filtering cylinder 141. The first filtering cylinder 141 is used to contain filtering liquid. One end of the first air pipe 142 is fixedly arranged on the upper mounting plate 12. The bottom of the first air pipe 142 is closed. The sidewall of the first air pipe 142 is provided with an array of first gas discharge holes 1421. The filtering liquid is higher than the first gas discharge holes 1421.

[0053] The upper closing plate 13 is fixedly arranged on the upper mounting plate 12. The upper closing plate 13 is provided with a communication groove 131. The first filtering cylinder 141 of one first filtering unit 14 is communicated with the first air pipe 142 of another first filtering unit 14 arranged in series through the communication groove 131.

[0054] The air suction branch pipe 41 is a steel wire hose, which effectively avoids the breakage of the air suction branch pipe 41.

[0055] The gas collection box 4 is provided with a negative pressure gauge 42. The pressure in the gas collection box 4 is monitored in real time through the negative pressure gauge 42, so as to ensure the adsorption effect of the gunpowder smoke.

[0056] Working principle: for multiple workstations related to gunpowder filling on the sensor production line for automobiles, the ends of the plurality of air suction branch pipes 41 on the gas collection box 4 extend to such gunpowder filling workstations. One gunpowder filling workstation is provided with at least one air suction branch pipe 41 for adsorbing smoke gas (air containing gunpowder smoke) to sufficiently purify the air of the gunpowder filling workstation. The gas adsorbed by the plurality of air suction branch pipes 41 is collected in the gas collection box 4.

[0057] When the filtering device works, the negative pressure generated by the vacuum generator 5 causes the negative pressure in the air inlet main pipe 18. The smoke gas collected in the gas collection box 4 is filtered in turn by the filter main body 1 and the precision filter 2. Then, the filtered gas is discharged through the air discharge barrel 3.

[0058] The filter main body 1 is filtered by the plurality of first filtering units 14 arranged in series. The filtering liquid contained in the first filtering cylinder 141 of the first filtering unit 14 can be distilled water. The airflow in the air inlet main pipe 18 passes through the first air pipe 142 of the first filtering unit 14 and enters the distilled water. Then, the airflow goes upwards and enters the communication groove 131 on the upper closing plate 13 through the first gas discharge hole at the top of the first filtering cylinder 141. Then, the airflow enters the first air pipe 142 of another first filtering unit 14 arranged in series. The above process is repeated until the last first filtering unit 14. The fully filtered gas enters the precision filter 2 through the air discharge main pipe 19 and is filtered again.

[0059] Example 2

[0060] The first vent pipe 142 is provided with a filter hole plate 143 on the side wall.

[0061] The filter hole plate 143 is located on the upper side of the first gas discharge hole 1421, which can prevent impurities in the filtering liquid from blocking the first gas discharge hole 1421 on the side wall of the first vent pipe 142.

[0062] Embodiment 3

[0063] The filter body 1 is provided with a first filter unit 14, a second filter unit 15, a third filter unit 16 and a fourth filter unit 17. The first filter unit 14 is provided with a first filter cartridge 141, the second filter unit 15 is provided with a second filter cartridge 151, the third filter unit 16 is provided with a third filter cartridge 161, and the fourth filter unit 17 is provided with a fourth filter cartridge 171. The first filter cartridge 141, the second filter cartridge 151, the third filter cartridge 161 and the fourth filter cartridge 171 are arranged in the filter body 1 in sequence.

[0064] On the one hand, the flow rate of the gas flow into the exhaust barrel 3 is reduced, and on the other hand, the gas flow first flows downward and then upward, which prolongs the length of the exhaust passage, and in combination with the silencer 32, the exhaust noise can be effectively reduced.

[0065] Embodiment 4

[0066] The first filter cartridge 141 is a transparent plastic cartridge, and the filter body 1 is provided with a plurality of sensors 17, one sensor 17 corresponding to one first filter cartridge 141.

[0067] The sensor 17 is used to detect the liquid level of the liquid in the first filter cartridge 141, so as to avoid insufficient filtering liquid.

[0068] Embodiment 5

[0069] The filter body 1 is provided with a protective shell 6, and the protective shell 6 is provided with a hinged door plate 61.

[0070] The protective shell 6 effectively protects and hides the first filter unit 14, and the hinged door plate 61 can be opened.

[0071] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
