The water cyclone (3) comprises an arc-shaped segment (31) and a bended segment (33) connected to the bottom of the arc-shaped segment (31), the arc-shaped segment (31) includes two symmetrical arcs, a plurality of stoppers (32) are arranged on an inner side of the arc-shaped segment (31), and the bended segment (33) is bended in the direction of a water baffle (4). The improved paint mist separating system accelerates the running speed of a paint mist mixture and makes the mixture form a spiral shape like a whirlwind by means of the horn-shaped and spiral design at the inlet (34), thus enhancing the mixing of paint mists and water.

Description

Improved paint mist separation system

Technical field

The invention relates to the technical field of paint mist treatment, in particular to an improved paint mist separation system.

Background technique

The painting process is carried out in the spray booth. During the painting process, the spray booth is filled with paint mist. In the prior art, the treatment of the paint mist is generally carried out by mixing the paint mist with water under a specific wind speed condition by a water spinner, and then feeding the mixed water into the slagging tank for the paint removal process, and finally discharging the separated water to the water. The device is recycled. In the above process of treating paint mist, due to the high wind speed requirement of the water spinner, it is affected by many factors, such as the water swirler is arranged at intervals, so it is often difficult to meet the requirements, and the mixing effect of the paint mist and water is not ideal. The separation rate of the paint mist is low, so it is necessary to pass the filter material before the exhaust air to reach the discharge standard, thereby greatly increasing the production cost.

Summary of the invention

The technical problem to be solved by the present invention is to provide an improved paint mist separation system which has a simple structure, reduces production cost, and can effectively perform paint mist separation.

In order to solve the above technical problems, the present invention relates to an improved paint mist separation system comprising a water tank, an air vent, and a water rotator disposed inside the water tank, the top of the water rotator is provided with an inlet, and the inlet is up and down Small flared shape, the inlet is provided with a convex spiral, the water swirler comprises a circular arc segment and a bending segment connected at the bottom of the circular arc segment, the circular arc segment comprises two symmetrical arcs, an arc A plurality of stoppers are disposed on the inner side of the segment, and the bent segments are bent in the direction of the water deflector.

Preferably, the bottom of the inlet is tangent to the top of the arc segment.

Preferably, the stops disposed on the two arcs in the arc segment are staggered with each other.

Preferably, the distance between the groove and the groove of each row of the water-blocking plate is referenced to the middle and gradually increases toward both ends. Generally speaking, the wind speed in the middle of the spray booth is relatively large, and the heads at both ends are small. The distance d of the labyrinth can be started from the middle and increased by 10 mm in turn.

Preferably, the water spinner is an integrally formed structure.

The invention has the beneficial effects that the improved paint mist separation system provided by the invention accelerates the running speed of the paint mist mixture through the horn shape and the spiral design at the inlet, and forms a spiral shape similar to a cyclone, which further enhances The combination of paint mist and water, the design of the water retaining plate effectively separates the paint mist from the water, and the system has a simple structure and reduces the production cost.

detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It should be noted that the words "front", "back", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, the words "inside" and "outside" "Respectively refers to the direction toward or away from the geometric center of a particular component.

Referring to Figures 1 and 2, the present invention relates to an improved paint mist separation system comprising a water tank 1, an air extraction opening 5 and a water swirler 3 disposed inside the water tank 1. The overflow of the water swirler 3 is higher than the top plate 2 of the water tank. The air outlet is provided on the left side of the water tank 1, and the water tank 4 is provided on the side of the water tank 1 opposite to the air outlet 5. The top of the water spinner is provided with an inlet 34, the inlet 34 is a large and small flared shape, and the inlet 34 is provided with a convex spiral 35, a flared inlet and a spiral design, which accelerates the running speed of the paint mist mixture. And to form a spiral shape that approximates a cyclone, further enhancing the mixing of the paint mist and water. The water rotator 3 further includes a circular arc segment 31 and a bending segment 33, which are formed by two arcs of a symmetry center located outside the water rotator, and the bending portion 33 is directed to the water deflector 4. The direction is bent. A plurality of stoppers 32 are disposed inside the circular arc segment 31 to enhance the mixing of the paint mist and the water. The water retaining plate 4 is formed into a 200 mm*25 mm groove type by using a carbon steel plate with a δ of 3.0 mm, and is evenly arranged in two rows. The spacing between the groove and the groove of each row of the water retaining plate is centered as a reference point, and gradually increases toward both ends. . Generally speaking, the wind speed in the middle of the spray booth is relatively large, and the heads at both ends are small. The distance d of the labyrinth can be started from the middle and increased by 10 mm in turn.

The flow direction of the paint mist in the system is as shown by the arrow in Fig. 1. The paint mist and water vapor are mixed into the water spinner. After being fully mixed, the water swirler enters the water tank, the paint residue is precipitated, and then the water retaining plate is passed. Enter the upper part of the sink and clean air is drawn through the air vent. Through the design of the reverse exhaust, the paint mist stays in the water for a longer period of time. The design of the arc segment, the bending section and the stop of the water swirler enhances the mixing of the paint mist and the water, and the design of the water retaining plate is effective. The separation of paint mist and water, and the system has a simple structure and reduces production costs.

The above is a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Anyone skilled in the art is within the technical scope of the present invention, Changes or substitutions that are not contemplated by the creative work are intended to be included within the scope of the invention.
