Detailed Description

Example 1.

Fig. 1 is a schematic structural diagram of the present invention, and the structure of the present invention is described with reference to fig. 1.

The portable waste gas treatment device for local spray painting of the gas cylinder comprises a sealing cover, a connecting pipe 8, a treatment box 9 and an exhaust fan 14. The sealing cover consists of a left cover body 1 and a right cover body 1, and the cover bodies 1 can rotate around shafts 19 at the upper parts of the cover bodies. During the use, the position that the sealed cowling lock needs the touch-up paint at gas cylinder 18, adopts standard 2 fastening in the lower part of the cover body 1, forms the operating space that sprays paint between the cover body 1 and the gas cylinder 18 surface, and the sealed cowling both ends baffle adopts

silica gel pad

3 and 18 surface sealings of gas cylinder, utilizes the fixed sealed cowling of frictional force of silica gel pad 3 and gas cylinder 18 surface simultaneously, can guarantee like this that the position of handle hole 4 aims at the position that needs the touch-up paint. The left and right cover bodies are respectively provided with an operation hole 4, and the operation holes 4 are covered with hole covers 5. Two operation holes are convenient for selecting the paint repair position, one operation hole is used for paint repair operation, and the other operation hole is sealed by a hole cover. Each cover body 1 is provided with an air exhaust hole 6, and the two air exhaust holes 6 are collected and communicated by an air exhaust pipe 7.

The connecting pipe 8 connects the suction pipe 7 and the air inlet pipe 17 of the treatment tank 9.

The treatment box 9 is a box body and box cover structure, and the rest is sealed except the openings of an air outlet pipe 16 and an air inlet pipe 17 on the box cover. The cavity in the treatment box 9 is divided into two cavities by a middle partition plate 14 below the box cover and paint treatment liquid 13 in the box, one is an air inlet cavity and the other is an air outlet cavity. The air outlet cavity is connected with an air outlet pipe 16 through an exhaust fan 15. The air inlet cavity is connected with an air inlet pipe 17, a sponge adsorption plate 11 suspended by a tension spring 10 is installed in the air inlet cavity, a plurality of dirt absorbing rods 12 are uniformly distributed below the sponge adsorption plate 11, and an inclined upward barb structure is arranged on the dirt absorbing rods 12. The sponge adsorption plate 11 can move up and down under the constraint of the middle partition plate 14 and the action of the tension spring 10. When the treatment box 9 does not work, the dirt absorbing rod 12 is positioned on the liquid level of the treatment liquid 13, and when waste gas is treated, the sponge adsorption plate 11 drives the dirt absorbing rod 12 to move up and down on the liquid level of the treatment liquid 13, so that dirt in the treatment liquid 13 can be adsorbed on the dirt absorbing rod 12 and on the lower surface of the sponge adsorption plate 11.

The lower extreme fixedly connected with screw thread post of extension spring 10, sponge adsorption plate 11's upper surface processing have with screw thread post assorted screw thread seat, and screw thread post connection conveniently dismantles sponge adsorption plate 11 and changes in the screw thread seat.

When a certain part of the gas cylinder needs to be repaired, the sealing cover is buckled with the gas cylinder 18, the position of the repaired paint corresponds to the operation hole 4, and the standard part 2 fastens the sealing cover. The exhaust fan 15 is started, and the paint repairing and spraying operation can be carried out. The waste gas of spraying paint gets into and handles case 9 through extraction opening 6, exhaust tube 7, connecting pipe 8, air-supply line 17, and whole waste gas gets into treatment fluid 13 after sponge adsorption plate 11 adsorption processes, filters through treatment fluid 13 again, is discharged from air-out pipe 16 by air exhauster 15 to realize the absorption of waste gas, filter the secondary treatment.

And after the paint repairing operation is finished, closing the exhaust fan 15, disconnecting the connecting pipe 8, loosening the standard part 2 and taking down the sealing cover. The paint repairing operation can be operated in a workshop or outside the workshop, and the device is convenient to disassemble, assemble and carry.

After the sponge adsorption plate is used for a certain time, the dirt on the sponge adsorption plate 11 is increased, the air permeability of the sponge is influenced, and the box cover can be opened to replace the sponge adsorption plate 11. When the dirt of the treatment liquid 13 increases, affecting the filtering capacity thereof, replacement is also required. In general, the sponge adsorption plate 11 is replaced twice and the treatment liquid 13 is replaced once.

Example 2.

In this example, the tension spring 10 and the adsorption rod 12 were removed, and the sponge adsorption plate 11 was fixed above the liquid surface of the treatment liquid 13 and was not in contact with the liquid surface, as compared with example 1. The waste gas can be absorbed by the sponge absorption plate 11 and filtered by the treatment liquid 13, and then is discharged after secondary treatment. Since the lower surface of the sponge adsorption plate 11 and the adsorption bar 12 are not used to clean the dirt in the treatment liquid 13, the treatment liquid 13 is replaced a little more times and the economy is little worse in this embodiment than in embodiment 1.

Example 3.

In this example, compared with example 2, the sponge adsorption plate 11 floats on the surface of the treatment liquid 13 and contacts the surface. The rest of the structure is the same. Compared with embodiment 1, the present embodiment has a simple structure without the tension spring 10 and the adsorption rod 12. Compared with embodiment 2, the lower surface of the sponge adsorption plate 11 can adsorb the dirt in the treatment liquid 13, which is beneficial to prolonging the working time of the treatment liquid.

The utility model discloses portable exhaust treatment device easy dismounting, waste gas reach environmental protection emission standard after the secondary treatment, are applicable to the local touch-up paint operation of gas cylinder very much. The operation environment is improved, the labor efficiency is improved, and raw materials and manpower are saved.
