Description

Improved paint mist capture water spinner

Technical field

The invention relates to the technical field of paint mist treatment devices, in particular to an improved paint mist capture water spinner.

Background technique

The water spinner is a device used to capture paint mist in a water-jet paint booth. The water and the air containing the paint mist enter the water spinner body at a certain ratio at the same time. The water overflows from the top plate of the water tank into the water swirler body, and the air containing the paint mist enters the water spinner body under the action of the exhaust fan due to the water and the paint mist. The speed difference of the gas in the water spinner body is very large, and the water is fully stirred and tumbling under the action of the high-speed airflow, and is fully contacted and mixed with the paint mist in the gas, thereby capturing the paint mist in the gas, and the paint mist capture rate can be Up to 99%.

The water spinner of the prior art adopts a vertical plate-shaped water inlet and an impact plate assembly below the water cooler cylinder. When used, excessive paint mist mixed in the water is easily deposited and adhered at the water inlet. The water overflowing into the water swirler body is made uneven and a flow is broken. After a period of use, the paint residue in the water will deposit on the impact plate, which is difficult to clean, and if it is not cleaned in time, it will easily affect the paint mist capture efficiency of the water-rotating spray booth, and increase the daily cleaning and maintenance workload. . In addition, the manufacturing process of the impact plate is cumbersome and relatively high in manufacturing cost. We have now canceled the structure of the impact plate and used the impact plate to capture the paint mist. However, after the actual operation, it was found that although the problem that the original impact plate was difficult to clean was solved, the lost paint mist was more, and the paint mist capture rate was not ideal.

Summary of the invention

The technical problem to be solved by the present invention is to provide an improved paint mist catching water spinner, The shape of the impact plate is changed, and the number of layers of the impact plate is increased, which greatly improves the paint mist capture rate.

In order to solve the above technical problem, the present invention provides an improved paint mist catching water spinner, which is disposed inside the water tank, and the water overflow of the water spinner is higher than the top plate of the water tank, and includes a cylinder body, and the inside of the cylinder body is oppositely provided with the first impact. a plate, a second impact plate and a third impact plate, wherein the second impact plate and the third impact plate are disposed on the same side of the cylinder, the first impact plate is disposed on the opposite side of the second impact plate, and the height is located on the second and third impact plates Between the second impact plate and the third impact plate having the same shape, the upper plate body portion is a concave curved surface, the upper plate surface end is a convex curved surface, and the first impact plate upper plate body portion The inner curved surface is a convex curved surface, the upper end of the cylinder is provided with a water inlet device, and the lower end is provided with a water outlet device, the water inlet device is a ring structure, including a bending portion and a connection And a fixing portion, the bending portion is bent toward a periphery of the cylinder, the fixing ear is connected to the bending portion through a connecting portion, and the fixing ear is provided with a fixing hole; the water discharging device is a slope which is inwardly contracted structure.

Preferably, the first impact plate and the second impingement plate have the same arc portion.

Preferably, the upper plate surface of the second impact plate extends above the upper plate surface of the first impact plate portion, and the lower plate surface of the first impact plate impact plate extends above the upper plate surface of the third impact plate portion.

Preferably, the water outlet device has an angle of 20° with the vertical plane.

Preferably, the water inlet device is fixed to the top plate of the water tank by bolts, and the bolt passes through the fixing hole. The height of the water inlet device is adjusted by adjusting the extension length of the bolt 6.

The invention has the beneficial effects that the impact plate design in the improved paint mist capture water rotator structure provided by the invention can make the water atomization more effective by the clever arc design. Capture paint mist and increase work efficiency.

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, 2, and 3, the present invention relates to an improved paint mist catching water spinner disposed inside a water tank having a water spout having a higher overflow than the water tank top 3. The water rotator comprises a cylinder 1, a water inlet device 7 disposed at an upper end of the cylinder 1, and a water outlet device 2 disposed at a lower end of the cylinder 1. The water outlet device 2 is a slope-shaped structure that contracts inward, and the water outlet device 2 and the vertical surface The angle is 20°. The inside of the cylinder is oppositely disposed with a first impact plate 4, a second impact plate 5 and a third impact plate 8, wherein the second impact plate 5 and the third impact plate 8 are disposed on the same side of the cylinder 1, the first collision The hitting plate 4 is disposed on the opposite side of the second impact plate 5, and the height is located between the second and third impact plates.
