Description

A rapid color-changing spray booth with a convex bottom and an air knife with double flaps

technical field

The utility model relates to a rapid color-changing spray booth with double flaps of an air knife in a convex bottom.

Background technique

The spray booth is the place where the workpiece is sprayed. The workpiece will generate a lot of dust during the spraying process. Therefore, the spray booth needs to be equipped with a device for removing and recovering dust. The device is generally installed at the bottom of the spray booth. In the existing dust removal and recovery devices, the bottom of the spray booth is generally set in a flat structure, and then air knives are set in the middle or at both ends to blow the dust on the bottom surface to the entrance of the dust collection device; the removal and recovery of such structures Because the dust device adopts a flat bottom surface, it is not conducive to the movement of dust towards the inlet of the dust collection device, and its dust removal and recovery efficiency is low, and the air knife needs to be equipped with a high-pressure air source, and dust will often accumulate on the bottom surface. Therefore, It is necessary to provide a spray booth with higher dust removal efficiency.

Utility model content

In order to solve the above problems, the utility model provides a rapid color-changing spray booth with double flaps of an air knife in a convex bottom.

The technical scheme that the utility model solves its technical problem adopts is:

A rapid color-changing spray booth with air knives and double flaps in a convex bottom, comprising a spray booth body and a powder cleaning device arranged at the bottom of the spray booth body, the powder cleaning device includes a bottom plate with an inverted V-shaped cross section, and is arranged on the bottom plate The air knife on the top and the recovery chamber for recovering dust. There are several air holes on the side wall of the air knife, and there is a gap between the two ends of the bottom plate and the side wall of the spray booth body. The entrance of the recovery chamber is connected to the gap, and the recovery The cavity is provided with an outlet that can be connected with a dust removal system.

A rotatable flap is arranged at the gap.

The turning plate is fixedly connected with a rotating shaft, the rotating shaft is rotatably installed in the spray booth body, the rotating shaft is parallel to the side wall and the bottom plate of the spray booth body, the rotating shaft is fixedly connected with one end of a connecting plate, and the connecting plate is another One end is pivotally connected to an output shaft of a cylinder or the cylinder, and the cylinder is integrally pivotally connected to the spray booth body.

The beneficial effects of the utility model are: the utility model adopts a bottom plate with an inverted V-shaped cross section. After the dust falls on the bottom plate, it will slide to the gap due to its own gravity, and at the same time, the air hole on the side wall of the air knife blows air. , to accelerate the dust to slide towards the gap. It can be seen that the dust removal efficiency of the spray booth adopting the above-mentioned structure is high, there is no need to configure a high-pressure air source, the structure is simple, and the cost is low. the

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is a structural representation of the powder cleaning device in the utility model;

FIG. 3 is a partial enlarged view A of FIG. 2 .

Detailed ways

Referring to Fig. 1, Fig. 2 and Fig. 3, the utility model is a rapid color-changing spray booth with air knives and double flaps in the convex bottom, including a spray booth body and a powder cleaning device arranged at the bottom of the spray booth body. The powder cleaning device includes The bottom plate 2 with an inverted V-shaped cross section, the air knife 3 arranged on the top of the bottom plate 2 and the recovery chamber 4 for dust recovery. There are a number of air holes 7 on the side wall of the air knife 3, and the air holes 7 are connected to the air source. The bottom plate 2 There is a gap 5 between the two ends and the side wall of the spray booth body. The inlet of the recovery chamber 4 communicates with the gap 5. The recovery chamber 4 is provided with an outlet 8 that can be connected to the dust removal system. The outlet 8 can be connected to the next-level system through the air duct 13. Connection, the air duct is made of PVC material (the prior art is made of metal pipe), and the use of PVC material can reduce the adhesion of dust on the inner wall of the air duct 13. The utility model adopts a bottom plate 2 with an inverted V-shaped cross section. After the dust falls on the bottom plate 2, it will slide to the gap 5 due to its own gravity, and at the same time, the air hole on the side wall of the air knife 3 blows air intermittently ( The blowing process is controlled by the pulse device) to accelerate the dust to slide towards the gap 5. It can be seen that the dust removal efficiency of the spray booth adopting the above-mentioned structure is high, there is no need to configure a high-pressure air source, the structure is simple, and the cost is low.

Before changing the powder color, the dust in the whole spray booth body needs to be cleaned up. In order to clean up the dust left in the recovery chamber 4 more conveniently, as shown in the figure, a rotatable flap 6 is provided at the gap 5 . During normal operation, the flap 6 rotates to be parallel to the bottom plate 2, and the dust enters the recovery chamber 4 under the action of its own gravity, exhaust fan and air knife, and then enters the next-level device through the air pipe 8 for processing; when the dust needs to be thoroughly cleaned The turnover plate 6 can be rotated to a vertical state, which is convenient for cleaning the dust in the recovery chamber 4 .

As shown in the figure, the turning plate 6 can be installed on the spray booth body 1 through the following specific implementation methods: the turning plate 6 is fixedly connected with a rotating shaft 9, and the rotating shaft 9 is rotatably installed in the spray booth body 1, and the rotating shaft 9 is connected to the spray booth body 1. The side wall of the main body 1 is parallel to the bottom plate 2, the rotating shaft 9 is fixedly connected to one end of a connecting plate 10, the other end of the connecting plate 10 is pivotally connected to the output shaft 12 of a cylinder 11, and the cylinder 11 is integrally pivotally connected to the spray booth body 1.

The above-mentioned embodiments are only preferred solutions of the utility model, and the utility model also has other implementation solutions. Those skilled in the art can also make equivalent modifications or replacements without violating the spirit of the present utility model, and these equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
