Example 1

As shown in fig. 1 and 2, the static pressure chamber includes a chamber body 10, a plurality of air inlets 11 are arranged at the top of the chamber body 10, and an air outlet is arranged at the bottom of the chamber body 10, wherein the air outlet is used for supplying air to a painting room of a coating line.

An air equalizing groove 20 is formed in the air inlet 11, the air equalizing groove 20 comprises a groove body 21, and a plurality of air holes 22 are formed in the groove wall of the groove body 21; the chamber body 10 is also provided with a plane filter screen 30 which completely covers the air outlet.

The air blown out by the fan enters the interior of the chamber body 10 through the air inlet 11, the air equalizing groove 20 and the air holes 22, and finally is blown out from the plane filter screen 30 and enters the interior of a painting room of the coating line.

The air equalizing groove 20 and the plane filter screen 30 are arranged, so that a dynamic pressure chamber can be replaced; because the dynamic pressure chamber is not arranged, the total height of the spray booth can be reduced, the space of a coating line is saved, and the one-time investment cost of equipment is reduced.

The working principle is as follows: air enters from the air inlet 11, uniformly enters the chamber body 10 under the action of the air equalizing groove 20, and then passes through the air equalizing of the plane filter screen 30, the air in the static pressure chamber uniformly enters the paint spraying chamber, and the air uniformly flows from top to bottom in the paint spraying chamber with uniform sedimentation wind degree in cooperation with the exhaust of the exhaust fan of the paint spraying chamber so as to meet the requirement of paint spraying.

Example 2

In the present embodiment, as shown in fig. 3, the groove body 21 has a square groove structure, i.e. a cross section of a rectangular groove structure.

The trough body 21 can be formed by splicing porous air-equalizing plates. The air equalizing groove 20 is fixedly installed at the top of the chamber body 10, and the groove of the air equalizing groove 20 is communicated with the air inlet 11.

The groove body 21 is simple in structure and convenient to manufacture and install.

Example 3

When the main frame of the groove body 21 is a square groove-shaped structure, then the edges at the left and right sides of the groove body 21 are further provided with inclined plane parts 23, as shown in fig. 2.

The inclined surface portion 23 is provided to make the wind blown out from the wind hole 22 on the side wall of the groove body 21 blow out at a larger angle, thereby being more beneficial to the rapid diffusion of the wind in the chamber body 10. Especially at low wind speeds, the wind equalizing velocity is higher with the inclined surface portion 23.

Example 4

In the embodiment 3, the included angle between the two inclined surface parts 23 is beta, and beta is more than or equal to 75 degrees and less than or equal to 90 degrees. If beta is too small, the total height of the groove body 21 will be increased, and the total height of the chamber body 10 needs to be increased correspondingly to ensure the air-equalizing effect, which is not suitable for the purpose of space saving.

If β is too large, the degree of freedom of the wind blown out from the wind holes 22 in the side wall of the chute body 21 is limited.

Example 5

The cross section of the groove body 21 is of an arc-shaped structure. In the trough body 21 with the structure, the wind blown out from the wind holes 22 is diffused, and when the wind is in a large static pressure chamber, the total height of the chamber body 10 is larger, and the wind equalizing effect is not good as that of the embodiment 3. Moreover, the processing and installation difficulty of the arc-shaped structure is higher.

Example 6

Typically, the air holes 22 are round holes. The structure is simple, and the processing is convenient.

Example 7

As shown in fig. 4, the air holes 22 are elliptical holes, the air holes 22 are arranged along the side wall of the tank body 21 into a plurality of first hole groups 22a and a plurality of second hole groups 22b, and the first hole groups 22a and the second hole groups 22b are arranged at intervals; the long axis direction of the air holes 22 in the first hole group 22a and the long axis direction of the air holes 22 in the second hole group 22b are perpendicular to each other.

That is, the wind holes 22 are arranged in several rows along the height direction of the groove 21, and the long axis directions of the wind holes 22 in two adjacent rows are different, as shown by the dotted line in fig. 4.

Optionally, a surge tank 20, labeled as tank a; the air equalization groove 20 adjacent to the A groove is marked as a B groove, a first hole group 22a in the A groove is arranged opposite to a second hole group 22B in the B groove, namely, the adjacent A groove and B groove are formed, and the first hole group 22a in the A groove is just opposite to the second hole group 22B in the B groove; similarly, the second hole set 22B in the slot a is disposed opposite, i.e., just opposite, the first hole set 22a in the slot B; this enables the wind blowing from the wind holes 22 in the first group of holes 22a to cross and meet the wind blowing from the wind holes 22 in the second group of holes 22b, and when meeting, can cancel out a part of the air flow impulse each other, thereby improving the wind-equalizing effect on the one hand, and enabling the wind energy in the static pressure chamber to be rapidly 'static pressure' (relative to the dynamic pressure chamber) on the other hand.

If the air holes 22 are circular holes, the above effect is not obtained. The elliptical holes, which are the central portions of the ellipse where the wind is concentrated, and the long axes of the wind holes 22 are not in the same direction, are advantageous to cancel each other out the impulse of the air current jetted from the wind holes 22.

In the embodiment, the static pressure chamber is simple and practical in structure, a dynamic pressure chamber does not need to be installed, space is saved, and one-time investment is reduced. Because, if make dynamic pressure room and static pressure room, the air chamber just need be made two-layer structure, and every layer needs more than 1.5 meters, and the total height of air chamber just reaches about 3 meters, and changes into the static pressure room only need do the one deck, and the total height only needs about 1.75 meters. The air that gets into is evenly distributed in the static pressure room, and the air that can be fine equally guarantees is even in the spray booth from top to bottom flows.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
